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 ...
TY - JOUR. T1 - Direct visualization of calcium oxalate monohydrate crystallization and dissolution with atomic force microscopy and the role of polymeric additives. AU - Guo, Shouwu. 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 ...

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 ...

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 ...

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 ...
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 ...

I am a 67 year old female in generally good health. I have been active most of my life,(competative gymnast and retired physical education teacher). Currently being treated for high blood pressure following arthroscopic surgery to correct a torn meniscus (from a fitness class). They had difficulty stabilizing my blood pressure after surgery. Prior to then I was told I had "White Coat Syndrome". Have a history of calcium oxalate kidney stones ( at least 4-5 episodes starting when I was 21), recently diagnosed with osteoporosis (told probably hereditary…parents died when I was 9 so no known history to confirm), calcium deposits on my lower left rib cage that I have been aware of for at least the last 15 years but now find the area below the deposit very tender and uncomfortable at times. I am using weight bearing exercise and dietary and supplemental support to address the osteoporosis. Is there anything I can do to reduce the calcium deposits on the ribs?. ...
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. ...
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?. ...

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 ...
