Relationship between supersaturation and calcium oxalate crystallization in normals and idiopathic calcium oxalate stone formers. (1/363)

BACKGROUND: In an earlier study on recurrent CaOx stone formers with no detectable abnormalities, we found that the urine of these subjects had a lower tolerance to oxalate load than controls and that the removal of urinary macromolecules with a molecular weight greater than 10,000 D improved their tolerance to oxalate. METHODS: The effects on CaOx crystallization of reduced urinary supersaturation of calcium oxalate (CaOx), induced by night water load, were studied in 12 normal males and in 15 male OxCa stone formers who were free from urinary metabolic abnormalities. The effect of the macromolecules, purified and retrieved from the natural and diluted urine, were analyzed in a metastable solution of CaOx. RESULTS: The water load caused an increase in urine volume (from 307 +/- 111 to 572 +/- 322 ml/8 hr, P = 0.014 in normal subjects, and from 266 +/- 92 to 518 +/- 208 ml/8 hr, P = 0.001 in the stone formers) and a concomitant reduction of the relative CaOx supersaturation (from 8.7 +/- 2.5 to 5.1 +/- 2.5 ml/8 hr, P = 0.001 in normal subjects, and from 10.4 +/- 3.5 to 5.0 +/- 2.7 ml/8 hr, P = 0.001 in the stone formers). The decrease in CaOx supersaturation was accompanied by an increase of the permissible increment in oxalate, both in normal subjects (from 43.8 +/- 10.1 to 67.2 +/- 30. 3 mg/liter, P = 0.018) and in the stone formers (from 25.7 +/- 9.4 to 43.7 +/- 17.1 mg/liter, P = 0.0001), without any significant variations of the upper limit of metastability for CaOx (from 21.6 +/- 5.3 to 20.5 +/- 4.2 mg/liter in normal subjects, and from 18.7 +/- 4.5 to 17.1 +/- 3.7 mg/liter in the stone formers). The inhibitory effect of urinary macromolecules with molecular weight greater than 10,000 Daltons did not undergo any change when the latter were recovered from concentrated or diluted urine, either in normal subjects or in the stone formers. CONCLUSIONS: Reduced CaOx supersaturation by means of water load has a protective effect with regards to CaOx crystallization in subjects who do not present any of the common urinary stone risk factors.  (+info)

Cell type-specific acquired protection from crystal adherence by renal tubule cells in culture. (2/363)

BACKGROUND: Adherence of crystals to the surface of renal tubule epithelial cells is considered an important step in the development of nephrolithiasis. Previously, we demonstrated that functional monolayers formed by the renal tubule cell line, Madin-Darby canine kidney (MDCK), acquire protection against the adherence of calcium oxalate monohydrate crystals. We now examined whether this property is cell type specific. The susceptibility of the cells to crystal binding was further studied under different culture conditions. METHODS: Cell-type specificity and the influence of the growth substrate was tested by comparing calcium oxalate monohydrate crystal binding to LLC-PK1 cells and to two MDCK strains cultured on either permeable or impermeable supports. These cell lines are representative for the renal proximal tubule (LLC-PK1) and distal tubule/collecting duct (MDCK) segments of the nephron, in which crystals are expected to be absent and present, respectively. RESULTS: Whereas relatively large amounts of crystals adhered to subconfluent MDCK cultures, the level of crystal binding to confluent monolayers was reduced for both MDCK strains. On permeable supports, MDCK cells not only obtained a higher level of morphological differentiation, but also acquired a higher degree of protection than on impermeable surfaces. Crystals avidly adhered to LLC-PK1 cells, irrespective of their developmental stage or growth substrate used. CONCLUSIONS: These results show that the prevention of crystal binding is cell type specific and expressed only by differentiated MDCK cells. The anti-adherence properties acquired by MDCK cells may mirror a specific functional characteristic of its in situ equivalent, the renal distal tubule/collecting ducts.  (+info)

Nucleation of calcium oxalate crystals by albumin: involvement in the prevention of stone formation. (3/363)

BACKGROUND: Urine is supersaturated in calcium oxalate, which means that it will contain calcium oxalate crystals that form spontaneously. Their size must be controlled to prevent retention in ducts and the eventual development of a lithiasis. This is achieved, in part, by specific inhibitors of crystal growth. We investigated whether promoters of crystal nucleation could also participate in that control, because for the same amount of salt that will precipitate from a supersaturated solution, increasing the number of crystals will decrease their average size and facilitate their elimination. METHODS: Albumin was purified from commercial sources and from the urine of healthy subjects or idiopathic calcium stone formers. Its aggregation properties were characterized by biophysical and biochemical techniques. Albumin was then either attached to several supports or left free in solution and incubated in a metastable solution of calcium oxalate. Kinetics of calcium oxalate crystallization were determined by turbidimetry. The nature and efficiency of nucleation were measured by examining the type and number of neoformed crystals. RESULTS: Albumin, one of the most abundant proteins in urine, was a powerful nucleator of calcium oxalate crystals in vitro, with the polymers being more active than monomers. In addition, nucleation by albumin apparently led exclusively to the formation of calcium oxalate dihydrate crystals, whereas calcium oxalate monohydrate crystals were formed in the absence of albumin. An analysis of calcium oxalate crystals in urine showed that the dihydrate form was present in healthy subjects and stone formers, whereas the monohydrate, which is thermodynamically more stable and constitutes the core of most calcium oxalate stones, was present in stone formers only. Finally, urinary albumin purified from healthy subjects contained significantly more polymers and was a stronger promoter of calcium oxalate nucleation than albumin from idiopathic calcium stone formers. CONCLUSIONS: Promotion by albumin of calcium oxalate crystallization with specific formation of the dihydrate form might be protective, because with rapid nucleation of small crystals, the saturation levels fall; thus, larger crystal formation and aggregation with subsequent stone formation may be prevented. We believe that albumin may be an important factor of urine stability.  (+info)

Temporal changes in mRNA expression for bikunin in the kidneys of rats during calcium oxalate nephrolithiasis. (4/363)

Inter-alpha-inhibitor and other bikunin-containing proteins are synthesized in relatively large quantities by the liver. These proteins function as Kunitz-type serine protease inhibitors and appear capable of inhibiting calcium oxalate (CaOx) crystallization in vitro. Preliminary studies have shown that renal tubular epithelial cells synthesize bikunin in response to CaOx challenge. To examine this response in vivo, a sensitive reverse transcription-quantitative competitive template-PCR was developed to detect and quantify poly(A)+ -tailed bikunin mRNA expression in kidney tissue from normal rats and rats developing CaOx nephrolithiasis after challenge with ethylene glycol. Bikunin mRNA expression in rat liver tissue was assessed as a positive control. The expression of bikunin mRNA in liver did not differ significantly between normal control rats and experimental rats with induced hyperoxaluria and renal CaOx crystallization. In contrast, there were significant temporal increases in the levels of bikunin mRNA expression in rat kidneys during CaOx nephrolithiasis after challenge with ethylene glycol. Urinary excretion of bikunin-containing proteins seemed to increase concomitantly. These findings indicate an association between the induction of hyperoxaluria/CaOx nephrolithiasis and the expression of the bikunin gene in rat kidneys.  (+info)

Essential arterial hypertension and stone disease. (5/363)

BACKGROUND: Cross-sectional studies have shown that nephrolithiasis is more frequently found in hypertensive patients than in normotensive subjects, but the pathogenic link between hypertension and stone disease is still not clear. METHODS: Between 1984 and 1991, we studied the baseline stone risk profile, including supersaturation of lithogenic salts, in 132 patients with stable essential hypertension (diastolic blood pressure of more than 95 mm Hg) without stone disease and 135 normotensive subjects (diastolic blood pressure less than 85 mm Hg) without stone disease who were matched for age and sex (controls). Subsequently, both controls and hypertensives were followed up for at least five years to check on the eventual formation of kidney stones. RESULTS: Baseline urine levels in hypertensive males were different from that of normotensive males with regards to calcium (263 vs. 199 mg/day), magnesium (100 vs. 85 mg/day), uric acid (707 vs. 586 mg/day), and oxalate (34.8 vs. 26.5 mg/day). Moreover, the urine of hypertensive males was more supersaturated for calcium oxalate (8.9 vs. 6.1) and calcium phosphate (1.39 vs. 0.74). Baseline urine levels in hypertensive females were different from that of normotensive females with regards to calcium (212 vs. 154 mg/day), phosphorus (696 vs. 614 mg/day), and oxalate (26.2 vs. 21.7 mg/day), and the urine of hypertensive females was more supersaturated for calcium oxalate (7.1 vs. 4.8). These urinary alterations were only partially dependent on the greater body mass index in hypertensive patients. During the follow-up, 19 out of 132 hypertensive patients and 4 out of 135 normotensive patients had stone episodes (14.3 vs. 2.9%, chi-square 11.07, P = 0.001; odds ratio 5.5, 95% CI, 1.82 to 16.66). Of the 19 stone-former hypertensive patients, 12 formed calcium calculi, 5 formed uric acid calculi, and 2 formed nondetermined calculi. Of the urinary factors for lithogenous risk, those with the greatest predictive value were supersaturation of calcium oxalate for calcium calculi and uric acid supersaturation for uric acid calculi. CONCLUSIONS: A significant percentage of hypertensive subjects has a greater risk of renal stone formation, especially when hypertension is associated with excessive body weight. Higher oxaluria and calciuria as well as supersaturation of calcium oxalate and uric acid appear to be the most important factors. Excessive weight and consumption of salt and animal proteins may also play an important role.  (+info)

Plasma calcium oxalate supersaturation in children with primary hyperoxaluria and end-stage renal failure. (7/363)

BACKGROUND: Children with primary hyperoxaluria type 1 (PH 1) are at great risk to develop systemic oxalosis in end-stage renal disease (ESRD), as endogenous oxalate production exceeds oxalate removal by dialytic therapy. As oxalate accumulates, calcium oxalate (CaOx) tissue deposition occurs. Children with other causes of ESRD, however, are not prone to CaOx deposition despite elevated plasma oxalate (POx) levels. METHODS: Our study objective was to examine the potential mechanisms for these observations. We measured POx, sulfate, citrate, and calculated CaOx saturation (betaCaOx) in 7 children with ESRD caused by PH 1 and in 33 children with non-PH-related ESRD. Maintenance hemodialysis (HD) was performed in 6 PH 1 and 22 non-PH patients: Pre- and post-HD levels were analyzed at this point and were repeated twice within 12 months in 5 PH 1 and 14 non-PH patients. Samples were obtained only once in 12 patients (one PH 1) on peritoneal dialysis (PD). After liver-kidney or kidney transplantation, plasma levels were measured repetitively. RESULTS: The mean POx was higher in PH 1 (125.7 +/- 17.9 micromol/liter) than in non-PH patients (44.2 +/- 3.3 micromol/liter, P < 10(-4)). All other determined anions did not differ between the two groups. betaCaOx was higher in PH 1 (4.71 +/- 0.69 relative units) compared with non-PH children (1.56 +/- 0.12 units, P < 10(-4)). POx and betaCaOx were correlated in both the PH 1 (r = 0.98, P < 2 x 10(-4)) and the non-PH group (r = 0.98, P < 10(-4)). POx and betaCaOx remained stable over time in the non-PH children, whereas an insignificant decline was observed in PH 1 patients after six months of more aggressive dialysis. betaCaOx was supersaturated (more than 1) in all PH 1 and in 25 out of 33 non-PH patients. Post-HD betaCaOx remained more than 1 in all PH 1, but in only 2 out of 22 non-PH patients. In non-PH children, POx and betaCaOx decreased to normal within three weeks after successful kidney transplantation, whereas the levels still remained elevated seven months after combined liver-kidney transplantation in two PH 1 patients. CONCLUSION: Systemic oxalosis in PH 1 children with ESRD is due to higher POx and betaCaOx levels. As betaCaOx remained supersaturated in PH 1 even after aggressive HD, oxalate accumulation increases, and CaOx tissue deposition occurs. Therefore, sufficient reduction of POx and betaCaOx is crucial in PH 1 and might only be achieved by early, preemptive, combined liver-kidney transplantation or liver transplantation alone.  (+info)

Inhibition of calcium oxalate crystal growth and aggregation by prothrombin and its fragments in vitro: relationship between protein structure and inhibitory activity. (8/363)

During blood coagulation, prothrombin (PT) is ultimately degraded to three fragments, thrombin, fragment 1 (F1) and fragment 2 (F2), which, collectively, contain all of the structural features of PT. One of these fragments, F1, is excreted in human urine and is the principal protein occluded into calcium oxalate (CaOx) crystals precipitated from it. This urinary form of F1, which we have named urinary prothrombin fragment 1 is present in calcium stones and is a potent inhibitor of CaOx crystallization in urine in vitro. The aim of this study was to determine whether PT itself and its other activation products, namely, thrombin, F1 and F2 also inhibit CaOx crystallization, by comparing their effects in a seeded, inorganic crystallization system. A secondary objective was to assess the relationship between the structures of the proteins and their inhibitory activities. PT was isolated from a human blood concentrate rich in vitamin K-dependent proteins. Following initial cleavage by thrombin, the resulting fragments, F1 and F2, were purified by a combination of reversed phase HPLC and low pressure column chromatography. The purity of the proteins was confirmed by SDS/PAGE and their individual effects on CaOx crystallization were determined at the same concentration (16.13 nM) in a seeded, metastable solution of CaOx using a Coulter Counter. [14C]Oxalate was used to assess deposition of CaOx and crystals were visualized using scanning electron microscopy. The Coulter Counter data revealed that the proteins reduced the size of precipitated crystals in the order F1 > PT > F2 > thrombin. These findings were confirmed by scanning electron microscopy which showed that the reduction in particle size resulted from a decrease in the degree of crystal aggregation. [14C]Oxalate analysis demonstrated that all proteins inhibited mineral deposition, in the order F1 (44%) > PT (27.4%) > thrombin (10.2%) > F2 (6.5%). It was concluded that the gamma-carboxyglutamic acid domain of PT and F1, which is absent from thrombin and F2, is the region of the molecules which determines their potent inhibitory effects. The superior potency of F1, in comparison with PT, probably results from the molecule's greater charge to mass ratio.  (+info)

These data are from all stones of 1201 patients who harbored no systemic disease as a cause of stones and whose stones contained CaOx and no uric acid, cystine, struvite or uncommon elements like drugs. For each patient we calculated the fraction of crystals that were calcium phosphate (CaP); the rest, given our exclusions, had to be CaOx.. But these were not ICSF, but idiopathic calcium stone formers because we included those with brushite in stones in order to compare HA and BR distributions.. For clarity we fitted the distribution of % CaP in stones from each patient as a continuous curve; the underlying data, remember, is the CaP% for a single patient.. At the left, the distribution peaks just above 2 % CaP meaning 98% or more CaOx.. The inset in the left panel uses a log transformation to expand the low range. A sizable peak of patients have less than 2% CaP (98% CaOx), and a huge fraction of patients have less than 10%.. This is clearly seen in the right hand panel. A large peak of ...

AU - Ward, Michael. AU - Wesson, Jeffrey A.. PY - 2002/5/28. Y1 - 2002/5/28. N2 - The growth and dissolution of calcium oxalate monohydrate (COM) were investigated by real-time in situ atomic force microscopy (AFM). The (100) surfaces of COM crystals were sufficiently rough that direct AFM imaging of terrace growth and step motion was not feasible. In undersaturated aqueous solutions, however, COM crystals dissolved, developing elongated hexagonal pits oriented along the [001] direction and having perimeters defined by {010} and {021} planes, which mimics the habit of the macroscopic crystals. Increasing the concentration of calcium oxalate to supersaturated levels reversed etching, resulting in gradual filling of the pits, which is tantamount to crystal growth. The confinement of growth within the pits permitted ...
TY - JOUR. T1 - Models for protein binding to calcium oxalate surfaces. AU - Gul, Asiya. AU - Rez, Peter. PY - 2007/4. Y1 - 2007/4. N2 - It is widely believed that proteins rich in Asp, Glu or Gla (γ carboxyglutamic acid) interact strongly with calcium oxalate surfaces and inhibit calcium oxalate crystal growth. An alternative hypothesis would be that the interaction of Asp, Glu and Gla residues with surfaces could facilitate nucleation and crystal aggregation. Prothrombin fragment 1 and bikunin have been studied extensively as inhibitors, β-microglobulin, transferrin and antitrypsin have been found in stone matrix and tubulin has been observed in the attachment of crystals to cell surfaces. The aim of this study is to examine how well carboxylate groups in proteins found either in stone matrix, or proposed as inhibitors, could fit with the calcium ion sub-lattice of both calcium oxalate monohydrate and dihydrate surfaces. The carboxylate groups in the acidic Asp, Glu and Gla residues were ...
Randalls plaque (RP) deposits seem to be consistent among the most common type of kidney stone formers, idiopathic calcium oxalate stone formers. This group forms calcium oxalate renal stones without any systemic symptoms, which contributes to the difficulty of understanding and treating this painful and recurring disease. Thus, the development of an in vitro model system to study idiopathic nephrolithiasis, beginning with RP pathogenesis, can help in identifying how plaques and subsequently stones form. One main theory of RP formation is that calcium phosphate deposits initially form in the basement membrane of the thin loops of Henle, which then fuse and spread into the interstitial tissue, and ultimately make their way across the urothelium, where upon exposure to the urine, the mineralized tissue serves as a nidus for overgrowth with calcium oxalate into a stone ...
Endogenous oxalate is primarily derived from the metabolism of glycine and ascorbic acid [1]. Calcium oxalate crystal related renal injury in the past was mostly due to JIB, which was a surgical weight-loss procedure performed for the relief of morbid obesity during the 1950s through the 1970s. However, there remained too many complications, including mineral and electrolyte imbalance, protein calorie malnutrition, enteric complications, and renal disease (hyperoxaluria, with oxalate stones or interstitial oxalate deposits). The multiple complications which were associated with JIB, led to a search for alternative procedures. In 1979 [2], one type of modern bariatric surgery was gastric bypass. Full procedure gastric bypass included RYGB surgery, biliopancreatic diversion with duodenal switch, vertical banded gastroplasty, and laparoscopic adjustable gastric banding. A study by Asplin et al. revealed a mean oxalate excretion of 83 mg/day in patients who underwent RYGB [3]. This was significantly ...
A physical chemical approach was used to study calcium oxalate monohydrate (COM) nucleation and growth on various organic interfaces. Self-assembling monolayers (SAMs), containing derivatized organic functional groups, were designed to mimic various amino acid residues present in both urine and stone matrix macromolecules. Derivatized surfaces include SAMs with terminal methyl, bromo, imidazole, and thiazolidine-carboxylic acid functional groups. Pronounced differences in COM deposition were observed for the various interfaces with the imidazole and thiazolidine surfaces having the greatest effect and the methyl and bromo groups having little or no nucleating potential.

Kidney stones can be classified according to their chemical composition. Some 64 percent of kidney stones are calcium oxalate stones. 80 percent of kidney stones are based on some calcium compound or other, and 80 percent of calcium-based kidney stones are calcium oxalate stones. Calcium oxalate is a calcium compound that is found in nature, in certain plants, and in deposits left on containers as a result of brewing beer, where its known as beer stones. Beer stones have to be removed by cleaning or they can ruin the flavor of subsequent batches of beer by harboring undesirable microorganisms. Rhubarb leaves have large amounts of calcium oxalate (and should be avoided by people suffering from kidney stones, as should other plants containing significant quantities of this mineral). Aside from brewing and dietary considerations, the main reason calcium oxalate stones are of concern to human beings is that they are the most common type of kidney stone, which is an often painful and sometimes ...

Its worth noting that healthy dogs typically have a urine pH of around 6.5. (H2O)x, where x varies from 0 to 3. As a common byproduct of human digestion and elimination, it is usually harmless. The
Approximately one third of patients with recurrent calcium stones have hyperuricosuria as one of their urinary risk factors (2). Increasing the urate concentration of experimental solutions effectively halves the amount of oxalate required to provoke calcium oxalate crystallization and increases the size of particles deposited (3). The pathophysiology of this relationship has been attributed to the ability of uric acid to salt out calcium oxalate. Salting out is simply the ability of an electrolyte, in this case uric acid, to reduce the solubility of a nonelectrolyte, in this case calcium oxalate (4). For the purposes of this definition, nonelectrolytes and electrolytes are salts that have low and high solubilities, respectively.. This phenomenon is distinct from epitaxy, whereby one crystal forms on another. (Although sodium urate can lead to crystallization of calcium oxalate in vitro, such an effect has not been demonstrated to occur in human urine and is now considered unimportant in ...
The present study aims to assess the potential changes in LncRNAs of proximal renal cells in response to the adhesion of calcium oxalate monohydrate (COM) crystals. lncRNA microarray were applied to evaluate the expression of HK-2 cells exposed to COM crystal for 0 and 24 hours.

Retention of crystals in the kidney is an essential early step in renal stone formation. Studies with renal tubular cells in culture indicate that hyaluronan (HA) and osteopontin (OPN) and their mutual cell surface receptor CD44 play an important role in calcium oxalate (CaOx) crystal binding during wound healing. This concept was investigated in vivo by treating rats for 1, 4, and 8 d with ethylene glycol (0.5 and 0.75%) in their drinking water to induce renal tubular cell damage and CaOx crystalluria. Tubular injury was morphologically scored on periodic acid-Schiff-stained renal tissue sections and tissue repair assessed by immunohistochemical staining for proliferating cell nuclear antigen. CaOx crystals were visualized in periodic acid-Schiff-stained sections by polarized light microscopy, and renal calcium deposits were quantified with von Kossa staining. HA was visualized with HA-binding protein and OPN and CD44 immunohistochemically with specific antibodies and quantified with an image ...

Basically, Arthritis is inflammation of the joints. There are currently over 100 forms of Arthritis and remarkably, that number continues to rise. The most common forms of Arthritis include: Osteoarthritis, Rheumatoid Arthritis, and Gout (see our next article, Symptoms of Arthritis for more information). Osteoarthritis is the result of degenerative joint disease, or simply wear and tear on the joints. Rheumatoid Arthritis is the result of an over active Immune System that results in inflammation. Gout is the oldest form of Arthritis and is the result of too much Uric Acid. The Uric Acid deposits crystals in the joints, leading to Gouty Arthritis. The joint pain, inherent to all Arthritis sufferers, is referred to as Arthralgia. Not only are the joints susceptible to attack, but the surrounding muscles, tissues, and organs are vulnerable to the effects of Arthritis as well. In fact, Arthritis has been known to attack the heart, kidneys, lungs, and liver ...
Low amounts of calcium in your diet will increase your chances of forming calcium oxalate kidney stones. Many people are afraid to eat calcium because of the name calcium oxalate stones. However, calcium binds oxalate in the intestines. A diet rich in calcium helps reduce the amount of oxalate being absorbed by your body, so stones are less likely to form. Eat calcium rich foods and beverages every day (2 to 3 servings) from dairy foods or other calcium-rich foods.. Also, eating high calcium foods at the same time as high oxalate food is helpful; for example have low fat cheese with a spinach salad or yogurt with berries. If you take a calcium supplement, calcium citrate is the preferred form.. ...
Kidney stone, scanning electron micrograph (SEM). Kidney stones are primarily formed by crystallization of the mineral salt calcium oxalate from the urine. They are irregular shaped stones called calculi (calculus) and are composed of random oriented columnar monoclinic crystals of calcium oxalate monohydrate (seen here) with peripheral deposits of fine octahedral crystals of calcium oxalate dehydrate. Patches of microcrystalline hydroxyl apatite fill internodal regions. Protein matrices can also be associated with the microcrystalline arrays. The hard stones can cause severe pain as they pass down the ureter (urinary tract). Kidney stones may need to be removed surgically using ultrasound.

Calcium oxalates are calcium salts of oxalic acid and they are the most common constituents of kidney stones. Kidney stones are the result of a crystal growth in the urinary tract and almost 10% of population experience such problems during their lifetime. Medical term of this process is known as the urolithiasis or nefrolithiasis. There have been many studies conducted with the aim to understand and explain the mechanism, precipitation conditions and possible prevention of the stone formation. Calcium oxalate crystallizes in three hydrate forms: thermodynamically stable monohydrate (whewellite, COM), the metastable modification, dihydrate (weddellite, COD) and trihydrate (caoxite, COT) which is rarely found in the kidney stones. The experimental results showed that a temperature changes and a concentration of citrate can influence morphology and size of precipitated crystals. Calcium oxalate crystals were studied by the means of thermal analysis (TGA) and infrared (FT-IR) spectroscopy. The ...
The aim of this application note is to present data from a model system to illustrate the use of the PIKE DiffusIR diffuse reflectance accessory in conjunction with the environmental temperature chamber. Specifically, the dehydration of calcium oxalate monohydrate was monitored in-situ. Calcium oxalate monohydrate has become a thermal analysis standard, and is also a primary chemical component found in kidney stones.

Use this medication exactly as prescribed by your doctor. Allopurinol is usually taken one or more times per day, depending on the dose. Take it just after a meal. It is recommended to start at a low dosage for treating gout - 100 mg once daily. After that, your doctor may increase your dose by 100 mg per day each week, until the maximum dose 800 mg daily is reached. Doses of 300 mg or less can be taken as a single daily dose, but higher doses should be split up into a few smaller doses per day. The recommended dose for preventing calcium oxalate kidney stones is 200 mg or 300 mg per day, taken as a single dose. Never take more than the prescribed dose ...
Serum creatinine and BUN were determined photometrically on the 3rd and 10th postoperative days. Results General No animal died immediately after operation or within the period of observation. Three animals developed a unilateral wedge-shaped, ischemic renal infarction. Parenchymatous destruction to a maximum depth of 3-20 tubular lumina could be found in all other kidneys. In two cases a stone was found in the renal pelvis. Diffractometric X-ray analysis showed the stone composition to be calcium oxalate monohydrate.

There are a variety of stones and crystals that can affect our dogs. Each type of crystal or stone, struvite or Oxalate, is addressed differently.
Since kidney stones cause most cases of acute unilateral obstructive uropathy, preventing these from forming can lower your risk of having a blockage. You can reduce your chances of having kidney stones by drinking six to eight glasses of water each day. Your doctor might recommend more if you have a history of kidney stones.. Keep an eye on how much salty food you eat, since too much sodium can increase your risk of having kidney stones. You may also look out for how many oxalates you eat. Oxalates are organic acids found in beets, rhubarb, spinach, blackberries, and soy products. This might help if youre prone to developing a specific type of kidney stone called a calcium oxalate stone. ...
The use of herbal supplements is growing. In a national U.S. survey of approximately 26,000 people, more than one-third of respondents reported using herbal supplements.3 Older age and higher education were associated with higher use of herbal supplements.. Even vitamins or minerals, when over-supplemented, can cause problems. The recommended daily vitamin C intake is 90 mg for men and 75 mg for women; these needs are easily met by a balanced diet. Many people take vitamin C (usually 1000 mg daily) to boost the immune system. Vitamin C supplementation in men is associated with increased kidney stones,4 likely due to increased urine levels of oxalate (a metabolite of vitamin C) and formation of calcium oxalate stones. Vitamin D calcium combination supplements, commonly taken for prevention of bone fractures, are also associated with increased risk of kidney stones5 as high body calcium levels leads to high urine calcium. It is interesting to note that the prevalence of kidney stones in the U.S. ...
Can someone clarify the NAC dosage for me? I read in the supplementsi chart that the dosage was 600 mg 2X per day, but I also see elsewhere that one should ramp up to 2400 (i.e. 1200 2 X per day). I am just starting on the protocol, is it correct to ramp up to the full 2400 mg of NAC daily before starting the doxycycline (my first antibiotic).. Also, I see the vitamin/supplement chart recommends 1 g Vitamin C 2 X per day. My local pharmacist recommends using regular ascorbic acid, not buffered, as I said I want to be cautious to prevent kidney stones with all of these supplementsi and calcium oxalate crystals in urine. Has anyone had any problems with taking 2 gm Vitamin C per day, unbuffered, such as gasto sensitivity, or other problems?. ...

The fly ash in two-step bioleaching dissolved earlier than that in one-step bioleaching while the calcium oxalate hydrate in two-step bioleaching formed earlier than that in one-step bioleaching. As there were minimal amount of metal ions in the medium, the formation of oxalate salts was insignificant in the pure culture and hence could not be detected in SEM, EDX and XRD analyses. The speculated growth mechanism in one-step bioleaching is the aggregation of swollen spores with fly ash particles after inoculation,. resulting in relatively large pellet nuclei. Adhesion of un-germinated spores and fly ash particle to the large pellet nuclei which contained newly-germinated spores and hyphae also occurred and resulted in a tendency to reduce the overall number of pellets in the medium [16] and [10]. This observation is consistent with the early findings of free spore aggregation Roscovitine of A.niger in batch flask culture and bubble-column fermenters [10]. Calcium oxalate precipitation affects ...

urine or solution can be undersaturated - the concentration of a stone forming salt like calcium oxalate is below its solubility (Region 1). Crystals will dissolve.. The solid curving line is the solubility. Stir sugar into water; no matter how long you stir, how much sugar is at the bottom of the glass, only so much will dissolve.. As in the experiment with sugar and water, when you heat the water, more of the crystals you stirred in will dissolve. Thus the solubility curve shifts to the left - more dissolved salts - as the temperature (vertical axis) rises (the way the graph is made increasing concentrations of salts are to the left!).. When the water cools to room temperature, the extra sugar, which means sugar dissolved at a concentration above its solubility at room temperature, produces supersaturation. You can follow the vertical line from x down to E which shows how cooling moves the concentration from undersaturation to extreme supersaturation.. But, crystals need not form if you ...

Calcium oxalate is the most common type of stone; 60% to 65% of kidney stones are comprised of calcium and oxalic acid, which form calcium oxalate crystals inside the kidneys. Some people are genetically predisposed to excreting high levels of oxalate in the urine (thus increasing the incidence of kidney stones), but this is not commonly the case. Instead, the lack of a beneficial bacteria found in the colon, called Oxalobacter formigenes, and/or uncombined intestinal oxalic acid are the culprits for calcium oxalate kidney stones. During normal digestion, calcium crystaizes with oxalate, never gets absorbed, and is eliminated in the stool. Oxalobacter formigenes uses oxalate as a source of energy, reducing the amount of oxalate in urine. A loss of Oxalobacter formigenes may result in elevated concentrations of urinary oxalate, increasing the risk of forming a calcium oxalate kidney stone. ...
Calcium oxalate (CaOx) is the major constituent of about 75% of all urinary stone and the secondary hyperoxaluria is a primary risk factor. Current treatment options for the patients with hyperoxaluria and CaOx stone diseases are limited. Oxalate degrading bacteria might have beneficial effects on urinary oxalate excretion resulting from decreased intestinal oxalate concentration and absorption. Thus, the aim of the present study is to examine the in vivo oxalate degrading ability of genetically engineered Lactobacillus plantarum (L. plantarum) that constitutively expressing and secreting heterologous oxalate decarboxylase (OxdC) for prevention of CaOx stone formation in rats. The recombinants strain of L. plantarum that constitutively secreting (WCFS1OxdC) and non-secreting (NC8OxdC) OxdC has been developed by using expression vector pSIP401. The in vivo oxalate degradation ability for this recombinants strain was carried out in a male wistar albino rats. The group I control; groups II, III, IV and V
Increased urinary oxalate excretion (hyperoxaluria) promotes the formation of calcium oxalate crystals. Monogenic diseases due to hepatic enzyme deficiency result in chronic hyperoxaluria, promoting end-stage renal disease in children and young adults. Ethylene glycol poisoning also results in hyperoxaluria, promoting acute renal failure and frequently death. Stiripentol is an antiepileptic drug used to treat children affected by Dravet syndrome. It has been shown to inhibit neuronal lactate dehydrogenase 5 enzyme. As this isoenzyme is also the last step of hepatic oxalate production, we hypothesized that stiripentol would potentially reduce hepatic oxalate production and urine oxalate excretion. In vitro, stiripentol decreased the synthesis of oxalate by hepatocytes in a dose-dependent manner. In vivo, oral administration of stiripentol significantly reduced urine oxalate excretion in rats. Stiripentol protected the kidneys against calcium oxalate crystal deposits in acute ethylene glycol ...

Calcium oxalate nephrolithiasis is a relatively common disease. The prevalence in the general population may range from 10 to 12 percent, and 0.4 to 1 percent of new cases are reported every year according to different series. Without specific pharmacological therapy, the recurrence rate in patient with established diagnosis of nephrolithiasis is extremely high and may range from 15 to 20 percent per year, with a cumulative incidence at five years ranging from 27 to 50 percent.Although genetic factors play an important role in the development of nephrolithiasis, environmental factors such as diet also appear to affect stone formation. Potassium citrate is also effective in preventing stone recurrence in patients with calcium oxalate nephrolithiasis. Low tolerability, however, may remarkably limit the use of these medication. Citrus fruits are a natural rich source of citrate and diet supplementation with juice of citrus fruits may represent a valuable alternative option to supply citrate without ...

Almost all quads at sometime in their life will have to deal with the unpleasant fact of having a kidney stone. Stones form for many reasons. If you dont drink enough water, for instance, you wont have enough urine to dilute chemicals. Then the chemicals may form crystals, which can develop into stones. A stone can be as small as a grain of sand or as large as a golf ball. Many small stones pass naturally. Medium-sized stones are often crushed with special high-tech equipment. Very large stones may require surgery. The composition of the stone can help reveal its cause and often suggest the form of treatment. There are basically three types of stones. Most stones are calcium oxalate, then there are cystine stones and finally infection stones. Calcium oxalate stones are composed of a hard salt compound. These are normally very small, smooth, round stones which often pass easily. Calcium oxalate stones can often be controlled by watching your diet and drinking lots of fluids. The uncommon and ...
Tea catechins, a subclass of compounds in the flavonoid family, have been found to have several biologically beneficial properties including antioxidative effects [29, 30]. Flavonoids leading to cytoprotective effects against oxidative stress. Our findings, taken together with other observations [27, 30-32], indicate that catechin demonstrates renoprotective abilities in several models of renal disease, especially nephrolithic nephropathy. The experiments indicate that catechins can attenuate functional and immunohistochemical changes in the renal proximal tubular cell line NRK-52E treated with COM and kidneys of EG induced nephrolithic rats.. In our in vitro study, catechin attenuated the changes of mitochondrial membrane potential, and normalized expression of SOD, 4-HNE, cytochrome c, and cleaved caspase 3 in the renal proximal tubular cell line NRK-52E treated with COM.. The disappearance of TMRE in NRK-52E cells indicated mitochondrial collapse through depolarization of the mitochondrial ...

By Dr. Marc Smith, DVM. So your dog is urinating blood, whining and trying to pee on every bush in your front yard. Oh well, its probably a UTI or he is just having a bad day and you hope it all just goes away. Well, lots of times, if it is just a UTI, it will go away. However, many times these problems dont go away because dogs with these symptoms commonly have bladder stones. This article discusses how to prevent the recurrence of calcium oxalate bladder stones in dogs.. Bladder stones in dogs are complicated as there are many different types that develop for many different reasons. For more questions and the latest research on the different types of stones and treatment, check out the Minnesota Urolith Center. This is the lab where I send stones for analysis.. So fast forward and say we have a diagnosis of stones and the stones have been surgically removed. Now, not all stones have to be removed surgically, but for the sake of this article, lets pretend they are. After removal, these stones ...
Bladder stones have long been relatively common in cats. In the past, the great majority of these stones were made out of struvite, but times have changed. Now, a cat is just about equally likely to develop struvite or calcium oxalate bladder stones. Read more.
Calcium ions are known to play an important part in signal transduction in stomatal guard cells. In Cummelina communis L., stomatal opening in isolated epidermis is strongly inhibited if the calcium concentration in the incubation medium is 0.1 mol mol m−3 or greater, It can be assumed that in the intact leaf, the apoplastic concentration of free calcium in the vicinity of the guard cells must be kept below this level if interference with stomatal functioning is to be avoided.. When C. communis was grown with 15 mol m−3 calcium in the rhizosphere, the concentration of free calcium in the xylem sap in the shoot was found to be 3.76 mol m−3. A mechanism is clearly needed for reducing this concentration as the sap traverses the apoplast between the xylem and the stomatal guard cells. Evidence is presented here that the deposition of calcium oxalate in cells of the leaf achieves the necessary regulation. The protective role of the six specialized subsidiary cells in this species appears to be ...

This case-controlled study was performed through the Minnesota Urolith Center. The objective was to determine the frequency of and interval until recurrence after initial ammonium urate, calcium oxalate and struvite uroliths in cats and whether breed, age, or gender was associated with increased risk for recurrence. In 1998, 4,435 cats were evaluated for an initial urolith episode and between 1998 and 2003 for recurrence episodes. Ammonium urate uroliths were found in 221 cats and 13.1% had an initial recurrence with a mean interval to recurrence of 22 months. Calcium oxalate uroliths were found in 2,393 cats and 7.1% had an initial recurrence with a mean interval of 25 months. Of 1,821 cats with struvite uroliths, 2.7% had a recurrence with a mean interval of 29 months. In all three types of uroliths, the largest percentage was located in the lower urinary tract.

N2 - Purpose: Iodinated contrast excreted into the renal collecting systems and ureters is of similar CT attenuation as kidney stones, making stones difficult or impossible to detect in contrast‐enhanced CT scans. This necessitates precontrast imaging for kidney stone work‐up. Our purpose was to determine the ability of CT dual‐energy subtraction imaging to selectively remove iodine signal while preserving the signal from kidney stones. Method and Materials: A phantom containing twenty kidney stones with different composition (calcium oxalate monohydrate, calcium hydroxyapatite, uric acid) and size (2 - 6 mm) was ...
Or, your doctor may give you a medication known as an alpha blocker which relaxes your ureter so as to pass the stone more easily. Also, ask the hospital for a strainer and urine holder as you will also need these. I was p calcium oxalate kidney stones fearful reading those first few posts but the procedure turned out to be quite painless. Many assume the most painful part of the kidney stone is the time it is exiting the body while passing through the urethra.
You can basically burn out some parts of the car that youre going to have to get.. puts you at risk of kidney stones or organ failure. There are no known, proven long-term benefits to.. Medical Intervention To Pass or Remove the Kidney Stone Sometimes a stone is simply too big to pass on its own. The kidneys may be blocked and/or there are other complications like infection or fever. Perhaps it has taken too long (up to 6 weeks with no successful passing is an average cut off).. Daily diet can affect the formation of kidney stones.. gradually forming stones. Kidney stones have many types, the most common (80-90%) are calcium stones, including calcium oxalate, calcium.. 6 Ml Kidney Stone 4mm Oct 30, 2014 · The Doctor Is In: Kidney Stones - Duration: 6:16.

Size of the stone is a major factor in whether it can pass naturally. ...
Oxalate (Ox) is a metabolic end product that is produced by the kidneys and is associated with several pathological conditions. The accumulation of oxalate in the body is one of the factors that lead to calcium oxalate kidney stones. To simulate the high-concentration Ox environment in vivo, we established an in vitro model of high Ox using renal tubular epithelial (HK-2) cells. Cell viability and proliferation were assessed to evaluate the effects of various concentrations (0, 0.25, 0.5, 1, 2, 4, 5, 8 and 10Mm) of Ox on HK-2 cells to select the optimum concentration and time to extract the exosomes ...
Phyllanthus niruri is an herb used in Brazil to treat kidney stones (urolithiasis.) The herb is known as quebra pedra or stone breaker. It has been previously shown to cause smooth muscle relaxation for easier passing of kidney stones. It has a pain relieving effect. It has been shown to prevent the growth of calcium oxalate crystals and prevent the growth of bladder stones. The herb has been demonstrated to be safe for human use.. The authors tested a series of patients who were given either P. niruri or a placebo treatment, for comparison. The extract used included alkaloids, flavonoids, terpenes, lignans, tannins and coumarins. P. niruri contains rutin, amylin, -sitosterol and caffeic acid (which are anti-inflammatory and/or analgesic,) geranin, quercetin (which inhibits phosphodiesterase,) niruside (which inhibits HIV reverse transcriptase,) and repandusinic acid A (which may protect the liver.). The testing included blood and urine calcium, magnesium, uric acid, oxalates, sodium and ...
Passing a kidney stone can feel as intense as labor pains minus the adorable bundle of joy. If youve gone through it, youre probably eager to prevent it from happening again. The good news is that your diet can make a big difference.. Medications, genetic disorders and medical conditions can all play a role in stone formation, says urologist Smita De, MD, PhD. But diet is a critical component for most patients.. The best diet to avoid kidney stones varies depending on the type of stone a patient makes since each has different risk factors. There are four main kinds of kidney stones, but the most common are calcium oxalate stones.. Health issues, such as diabetes or osteoporosis, can also affect stone development and dietary recommendations. So its essential to consider these factors when developing the best kidney stone diet plan for you.. But these seven general guidelines are good for most people whove had stones, says Dr. De. ...
Magnesium oxalate is an inorganic compound comprising a magnesium cation with a 2+ charge bonded to an oxalate anion. It has the chemical formula MgC2O4. Magnesium oxalate is a white solid that comes in two forms: an anhydrous form and a dihydrate form where two water molecules are complexed with the structure. Both forms are practically insoluble in water and are insoluble in organic solutions. Some oxalates can be found in nature and the most known naturally occurring oxalates are whewellite and weddellite, which are calcium oxalates. Magnesium oxalate has been found naturally near Mill of Johnston which is located close to Insch in northeast Scotland. The naturally occurring magnesium oxalate is called glushinskite. The magnesium oxalate was found at the lichen and rock interface on serpentinite. It was found in a creamy white layer which was mixed in with the lichen fungus. A scanning electron micrograph of samples taken showed that the crystals had a pyramidal structure with both curved and ...
Research from a team of investigators, including University of Houston scientists, could lead to a new treatment to prevent calcium oxalate kidney stones.
Previous research on proteins that inhibit kidney stone formation has identified a relatively small number of well-characterized inhibitors. Identification of additional stone inhibitors would increase understanding of the pathogenesis and pathophysiology of nephrolithiasis. We have combined conventional biochemical methods with recent advances in mass spectrometry (MS) to identify a novel calcium oxalate (CaOx) crystal growth inhibitor in normal human urine. Anionic proteins were isolated by DEAE adsorption and separated by HiLoad 16/60 Superdex 75 gel filtration. A fraction with potent inhibitory activity against CaOx crystal growth was isolated and purified by anion exchange chromatography. The protein in 2 subfractions that retained inhibitory activity was identified by matrix-assisted laser desorption/ionization-time-of-flight MS and electrospray ionization-quadrupole-time-of-flight tandem MS as human trefoil factor 1 (TFF1). Western blot analysis confirmed the mass spectrometric protein ...
Various types of crystalloids (oxalate, uric acid calcium, and cystine) are present in urine, which are kept in solution by the presence of colloids (mucin and sulphuric acid) in urine by the process of absorption. There is imbalance in the crystalloid colloid ratio. i.e. increase in crystalloid and fall in colloid level leading to formation of renal stones (Hadimioglu, Saadawy, Saglam, Ertug, & Dinckan, 2008). Urinary stone are formed when colloid lose the solvent action or adhesive property. In ethylene glycol induced urolithic rats observed that an elevated level of urinary phosphorus are responsible for stone formation. Increased excretion of uric acid has been observed for stone formation. The predominance of uric acid crystals in calcium oxalate proteins are capable of binding to calcium oxalate and modulate its crystallization also play an important role in stone formation. Super saturation of urinary colloids results in precipitation as crystal initiation particle(Aksu, Demirci, & Ince, ...

The low oxalate diet consists of consuming a diet low in oxalates. It is a newer diet for autism that came about from the work of Susan Owens and the observation from parents that foods high in oxalates were problematic for their children.. While this is a newer diet, there is a lot of science that helps explain what might be going on for some children with autism. Oxalates are sharp crystals and are the same ones responsible for certain forms of kidney stones. Oxalate crystals can be inflammatory and damaging to a childs delicate biochemistry and the low oxalate diet reduces these compounds. In cells, oxalates can lead to oxidative damage, depletion of glutathione, pain associated with urination, and inflammation related to the immune system. Glutathione is important for immune function, inflammatory regulation, detoxification, and antioxidant status. Levels of glutathione are often low in children with autism; therefore oxalates could exacerbate challenges for some of these ...
A 55-year-old man in China underwent close to three hours of surgery after a CT scan revealed his system was completely packed with kidney stones. The patient, identified only as Mr. He, had an astounding 420-plus kidney stones removed. Now, his doctor believes his tofu-rich diet is to blame.. The shocking discovery of hundred of kidney stones was made after Mr. He complained of terrible stomach pains. He was booked for an emergency operation because his condition left him unable to urinate, and doctors feared they would have to remove the kidney entirely if the stones werent removed immediately.. Kidney stones are caused by a buildup of calcium, which hardens in the kidney and prevents normal functions. In this case, Mr. Hes doctors believed that his daily intake of tofu caused the massive blockages.. According to Dr. Lindsey Mcilvena, a member of SuperFoods Medical Advisory Board, Mr. Hes kidney stones were likely composed of calcium oxalate or calcium phosphate, as 80% of stones contain ...

Interestingly, around the same period of time I was rotating in nephrology consult service and had an elderly patient with history of paraplegia and neurogenic bladder (on intermittent self-catheterization), who was brought to the ER with altered mental status for which he was intubated for airway protection. On presentation, he was found to have acute kidney injury (Cr 6.0). His renal function continued to deteriorate with no specific etiology for his renal failure, so he had a renal biopsy which showed evidence of an active tubulointerstitial nephritis with marked tubular injury and calcium oxalate crystals present within the tubular lumina. Remarkable findings in his history included the recent use of cannabinoids. He never had history of renal stones. His home medication includes: methadone, oxycodone, nortriptyline and pregabalin. Admission labs showed normal osmolar gap and negative toxicology analysis. Urine microscopy showed muddy brown casts with no identifiable crystals. Abdominal ...
The consequences of ethylene glycol intoxication are described in a 42 year old man who presented with a profound metabolic acidosis, cardiogenic shock and renal failure. The clinical and electrocardiographic findings suggested a myocarditis and this was confirmed by endomyocardial biopsy. The striking absence of neurological features in this patient delayed diagnosis, which was not suspected until calcium oxalate crystals were demonstrated at renal biopsy. Retrospective analysis of serum retained at his admission to hospital confirmed toxic levels of ethylene glycol. Following a period of intensive cardio-respiratory support and peritoneal dialysis he made a good recovery with cardiac and renal function returning to normal.. ...

Authors: Giannossi, Maria Luigia , Mongelli, Giovanni , Tateo, Fabio , Summa, Vito Article Type: Research Article Abstract: Kidney stones are a very frequent finding in southern Italy, but stone analysis is not routinely performed. However, it is an important requirement not only for a successful treatment of this disease, but also for the prophylaxis to prevent any recurrence. We therefore set out to analyze 80 kidney stones collected from Basilicata Region (Southern, Italy). X-ray powder diffraction as well as optical and scanning electron microscopy and petrographic thin section analysis have been …applied in order to determine the mineralogical and morphological compositions. The internal structure and the relation between major and minor components have facilitated the classification of the kidney stones according to a detailed scheme. As it is known from other country, calcium oxalate stones were the most frequent (59%) [39% mainly composed of whewellite, CaC_2 O_4 *H_2 O and 29% is ...
Oxalate, a non-essential end product of metabolism, causes hyperoxaluria and eventually calcium oxalate (CaOx) stone disease. Kidney cells exposed to oxalate stress results in generation of reactive oxygen species (ROS) and progression of stone formation. Perturbations in endoplasmic reticulum (ER) result in accumulation of misfolded proteins and Ca2+ ions homeostasis imbalance and serve as a common pathway for various diseases, including kidney disorders. ER stress induces up-regulation of pro-survival protein glucose-regulated protein 78 (GRP78) and pro-apoptotic signaling protein C/EBP homologous protein (CHOP). Since the association of oxalate toxicity and ER stress on renal cell damage is uncertain, the present study is an attempt to elucidate the interaction of GRP78 with oxalate by computational analysis and study the role of ER stress in oxalate-mediated apoptosis in vitro and in vivo. Molecular docking results showed that GRP78-oxalate/CaOx interaction takes place. Oxalate stress ...
On this diet, we elminate foods that are high in oxalates, mostly certain fruits and vegetables, a lot of grains, nuts, and seeds. Beef, chicken, pork, eggs, and fish contain no oxalates and can be eaten freely. The goal is stay low oxalate, but even doing low and medium oxalate will help symptoms, and that is what we are doing right now until we can get a handle on the diet and learn how many oxalates Lynsey can handle a day. What is an oxalate?. (Since we are very new to this diet, and I am still learning, I will paste the answers to these questions from another web site and include the link if you want to explore that web site more.). Here is a link to Great Plains Laboratory and their explanation of oxalates, and particularly how it relates to autism. It is very informative. http://www.greatplainslaboratory.com/home/eng/oxalates.asp. From http://lowoxalate.info/ : Oxalate is a molecule that links up with calcium and then crystalizes under some conditions, including when it encounters ...
Before we get into down side of elevated oxalates it is important to repeat something I said my previous post titled Oxalates and MTHFR: Understanding the Gut-Kidney Axis - that oxalates in mild amounts are not a problem for the body. As long as the body can safely detoxify each molecule of oxalate, they will not bother us. Even though they are nasty in high amounts, the body has the ability to get rid of oxalates. We have already seen how proper digestion and gallbladder function protects us from absorbing oxalates. What we havent talked about yet is how our body gets rid of oxalates once they enter and build up to toxic levels. Unfortunately life is all about tradeoffs and that principal holds true when it comes to how the body detoxifies oxalates.. Any discussion of oxalates is incomplete without mentioning sulfate. Sulfate is one of the most amazing molecules in our bodies. Sulfate is an essential byproduct of our methylation cycle and without it we cannot survive. Sulfate helps us seal our ...

Anyone who has ever had a kidney stone knows that it is an extremely painful condition, especially if the stone is stuck in the urethra, the channel leading from the kidney to the bladder.. Even when it is in the urinary bladder, the stone must first pass through the urethra. Because men have longer urinary channels, they have a bigger problem with this condition, hence called delivery boy.. This is a natural recipe that helps in dissolving the stones and reducing the unpleasant pain.. What are kidney stones?. Kidney stones are typically the mineral deposit - a form of calcium like calcium oxalate - deposited in the kidneys, which forms small stones as sand inside the kidneys.. The stone may remain in the kidney for weeks, months or even years without causing symptoms. However, if it moves, an extreme pain in the back, hips and bloody, muddy urine may appear.. At that moment, a large amount of fluids is recommended to flush the stone through urination, and analgesics for pain relief. However, ...

The hormone prolactin stimulates lactation (production of breast milk). Dopamine, released by the hypothalamus stops the release of prolactin from the pituitary gland. Domperidone, by acting as an anti-dopaminergic agent, results in increased prolactin secretion, and thus promotes lactation (that is, it is a galactogogue). In some nations, including Australia, domperidone is used off-label, based on uncertain and anecdotal evidence of its usefulness, as a therapy for mothers who are having difficulty breastfeeding.[24][25] In the United States, domperidone is not approved for this or any other use.[26][27] A study called the EMPOWER trial was designed to assess the effectiveness and safety of domperidone in assisting mothers of preterm babies to supply breast milk for their infants.[28] The study randomized 90 mothers of preterm babies to receive either domperidone 10 mg orally three times daily for 28 days (Group A) or placebo 10 mg orally three times daily for 14 days followed by domperidone ...

An increased plasma transferrin level is often seen in patients suffering from iron deficiency anemia, during pregnancy, and with the use of oral contraceptives, reflecting an increase in transferrin protein expression. When plasma transferrin levels rise, there is a reciprocal decrease in percent transferrin iron saturation, and a corresponding increase in total iron binding capacity in iron deficient states[14] A decreased plasma transferrin can occur in iron overload diseases and protein malnutrition. An absence of transferrin results from a rare genetic disorder known as atransferrinemia, a condition characterized by anemia and hemosiderosis in the heart and liver that leads to heart failure and many other complications. Transferrin and its receptor have been shown to diminish tumour cells when the receptor is used to attract antibodies.[9] ...
