Adrenosympathetic overactivity under conditions of work stress. (1/17)

Serial measurements of urinary adrenaline, noradrenaline, and 11-hydroxycorticosteroid excretion were performed on 32 healthy men under two conditions of work stress; piecework and work on assembly line. A statistically significant increase in adrenaline, noradrenaline, and 11-hydroxycorticosteroids was observed for piecework and assembly line workers compared with salaried and 'ordinary' workers. The results support the assumption that psychosocial factors of an everyday type have significant effects on the sympathoadrenomedullary and adrenocortical function.  (+info)

The factors controlling stem cell recirculation. II. ACTH-induced inhibition of migration of hemopoietic stem cells. (2/17)

Injections of ACTH of prolonged action (twice 1.5 units per mouse) given to lethally (800 R) irradiated mice with a hind limb shielded to the middle of the tibia brought about a twofold decrease in the number of spleen colonies. ACTH injections after sublethal whole-body irradiation (600 R) did not affect the number of endogenous spleen colonies. ACTH injection of normal mice brought about a substantial decrease in the CFU content in the circulating blood at the time of increased 11-hydroxycorticosteroid concentrations in the plasma. The results obtained are interpreted as inhibition of CFU migration from a shielded area of bone marrow induced by a high 11-hydroxycorticosteroid content in the plasma that followed ACTH injections which had no mitostatic effect on CFU proliferation.  (+info)

Adrenal function in 23 children with paracoccidioidomycosis. (3/17)

Adrenal involvement by Paracoccidioides brasiliensis was described at necropsies and in many clinical studies, but only in adults. Therefore, the aim of this study was to evaluate adrenal function in children with paracoccidioidomycosis. Twenty-three children with the systemic form of paracoccidioidomycosis were evaluated and divided in two Groups: Group A (n = 8) included children before treatment and Group B (n = 15) children after the end of treatment. Plasma cortisol (basal and after ACTH test), ACTH, renin activity, aldosterone, sodium and potassium were measured. They were within normal range in all cases, except for renin activity and aldosterone, which were elevated in some cases. Group A patients showed basal and post-ACTH cortisol levels significantly greater than Group B patients. The results showed that adrenal function was not compromised in these children with paracoccidioidomycosis.  (+info)

Cushing's syndrome due to huge adrenocortical multinodular hyperplasia. (4/17)

A case of Cushing's syndrome due to huge adrenocortial multinodular hyperplasia who was shown to be hyperresponsive to ACTH administration, unresponsive to metyrapone administration and resistant to dexamethasone high dose suppression was reported. After two years' duration of his symptoms, the multinodular adrenals weighing 161 g in total were removed by bilateral adrenalectomy which abolished his symptoms. Postoperatively, plasma ACTH rose gradually to above normal levels, suggesting the presence of primary disorder in the hypothalamus-pituitary axis.  (+info)

Precocious development of UDP-glucuronyltransferase activity in chick-embryo liver after administration of adrenocorticotropic hormone and of certain 11beta-hydroxy corticosteroids. (5/17)

1. Precocious development of UDP-glucuronyltransferase (EC 2.4.1.17) and of glucuronidation by endogenous compounds of known chemical composition is reported for the first time. 2. This development occurs precociously in chick-embryo liver after administration to the egg of mammalian adrenocorticotropic hormone, of Synacthen (a synthetic compound possessing adrenocorticotropic activity), or of certain corticosteroids possessing a hydroxy or an oxo group at C-11. 3. Corticosterone-dependent transferase development parallels the rise of infused corticosterone in plasma, but does not require the presence of embryo pituitary in ovo, and is demonstrable in embryo liver explants in vitro. 4. Competence of embryo liver transferase to respond to corticosterone (or dexamethasone) begins over days 13-14, the time of competence to respond to grafted pituitary gland. 5. The transferase appearing after treatment with corticosterone or adrenocorticotropic hormone, like that appearing after pituitary grafting or on natural development and unlike that from the untreated embryo, is markedly activated by membrane-perturbation procedures, suggesting it appears through induction, not activation. 6. Thyroxine and tri-iodothyronine accelerate transferase development after treatment with adrenocorticotropic hormone or corticosteroid to the rate seen after pituitary grafting. 7. A wide range of other hormones and steroids did not obviously influence transferase development in this system. 8. We suggest that grafted pituitary gland evokes precocious transferase development in embryo liver through production of adrenocorticotropic hormone and hence of the active corticosteroids; thyrotropin and thyroxine hasten the process. The role of this mechanism in the natural development of UDP-glucuronyltransferase is discussed.  (+info)

Comparison of corticotrophin and corticosteroid response to lysine vasopressin, insulin, and pyrogen in man. (6/17)

Plasma corticotrophin (ACTH) and corticosteroid levels in response to lysine vasopressin (LVP), insulin hypoglycaemia, and pyrogen have been compared in seven subjects with normal pituitary adrenal function. Intramuscular vasopressin was a weak stimulus to corticotrophin release, peak values lying within the range 49 to 141 pg/ml. Insulin hypoglycaemia consistently caused a more noticeable increase, with peak levels between 114 and 364 pg/ml, while pyrogen was the most powerful, corticotrophin levels rising to between 209 and 1,725 pg/ml. Peak plasma corticosteroid levels showed less pronounced differences between the three tests, and correlated poorly with peak ACTH levels. Thus, relatively small acute changes in corticotrophin levels produce near-maximal adrenal stimulation. Under these conditions, plasma corticosteroid measurements do not accurately reflect circulating corticotrophin levels. These findings help to explain the physiological basis of several observations on the corticosteroid responses to these clinical test procedures.  (+info)

Effects of metoclopramide and bromocriptine on the renin-angiotensin-aldosterone system in man. Dopaminergic control of aldosterone. (7/17)

This study was designed to investigate the possible role of dopaminergic mechanisms in the control of the renin-angiotensin-aldosterone system in normal man. Six normal male subjects in metabolic balance at 150 meq sodium, 60 meq potassium constant intake received the specific dopamine antagonist, metoclopramide, 10 mg i.v. or placebo followed by angiotensin II infusion 1 h later on 2 consecutive days. Metoclopramide increased plasma aldosterone concentration from 8.2+/-2.2 to 21.0+/-3.3 ng/100 ml (P < 0.005) and plasma prolactin concentration from 18.0+/-4.0 to 91.7+/-4.0 ng/ml (P < 0.001) within 15 min of its administration. At 1 h, plasma aldosterone and prolactin concentrations remained elevated at 16.8+/-2.1 ng/100 ml (P < 0.01) and 86.8+/-15.9 ng/ml (P < 0.005), respectively. Angiotensin II at 2, 4, and 6 pmol/kg per min further increased plasma aldosterone concentration to 27.2+/-3.4, 31.9+/-5.7, and 36.0+/-6.7 ng/100 ml (P < 0.02), respectively. Placebo did not alter plasma aldosterone or prolactin concentrations, but angiotensin II increased plasma aldosterone concentration to 13.7+/-2.4, 19.0+/-1.9, and 23.3+/-3.2 ng/100 ml (P < 0.005). The increment of plasma aldosterone concentration in response to angiotensin II was similar after metoclopramide or placebo. The six subjects also received the dopamine agonist, bromocriptine, 2.5 mg or placebo at 6 p.m., midnight, and 6 a.m. followed by angiotensin II infusion on 2 consecutive d. Bromocriptine suppressed prolactin to <3 ng/ml. After placebo, plasma aldosterone concentration increased from 5.2+/-1.4 to 12.3+/-1.7, 17.2+/-2.2, and 21.8+/-3.5 ng/100 ml (P < 0.01) and after bromocriptine from 7.2+/-1.0 to 14.7+/-3.0, 19.8+/-3.2, and 23.4+/-1.6 ng/100 ml (P < 0.001) with each respective angiotensin II dose. No difference in the response to angiotensin II after bromocriptine or placebo was observed. Plasma renin activity, free 11-hydroxycorticoid concentration, and serum potassium concentration were unchanged by metoclopramide or bromocriptine. The results suggest that aldosterone production is under maximum tonic dopaminergic inhibition which can be overridden with stimulation by angiotensin II in normal man.  (+info)

The circadian rhythms of human subjects without timepieces or indication of the alternation of day and night. (8/17)

1. Seven solitary subjects, and two groups of four, spent from 5 to 13 days in an isolation unit without knowledge of time. Three solitary subjects and one group of four adopted fairly regular activity habits with a period of 25-27 h; one subject adopted a period of 30 h, and one of 27 h initially, decreasing to 24-25 h after a few days. One group of four awoke roughly every 24 h, after a sleep which was alternately about 8 h, or about 4 h and believed by the subjects to be an afternoon siesta. Two solitary subjects alternated sleeps of about 8 or 16 h, separated by 24 h of activity.2. Deep temperature in all subjects oscillated with a period of 24-26 h, which was thus commonly distinct from their activity habits.3. Urinary potassium followed a rhythm whose period, though usually close to, was sometimes distinct from, that of temperature. A secondary period corresponding to that of activity was also sometimes present.4. Urinary sodium and chloride usually gave evidence of two periodic components, one corresponding to activity and the other to the rhythm of either temperature or of urinary potassium.5. Urinary creatinine and phosphate usually followed the subject's routine of activity.6. Plasma samples were collected on a few occasions and analysed for phosphate and 11-hydroxycorticosteroids. Changes in plasma phosphate were usually, but not always, associated with similar changes in urinary phosphate, and changes in plasma corticosteroids were often, but not always, associated with similar changes in urinary potassium shortly afterwards.7. Observations are recorded on a subject alone in a cave for 127 days. His activity habits, though wildly variable, gave evidence of a period of 25.1 h and his urinary electrolyte excretion indicated a shorter period, of 24.6 h. During the following 3 days, when he remained in the cave but was visited frequently, his plasma corticosteroids and urinary potassium oscillated with a period of 16 h.8. The possible mechanisms controlling these rhythms are discussed.  (+info)

In order to determine the role of mitochondrial DNA mutations in thyroid tumorigenesis, Abu-Amero et al. (2005) sequenced the entire mtDNA from 24 thyroid tumor specimens and four thyroid cancer cell lines. Somatic mutations were identified in 37% of primary thyroid carcinomas (PTC) and among 25% of multinodular hyperplasia cases. Most mutations were nucleotide substitutions resulting in missense mutations. Of these sequence changes, 14 were nonsynonymous and 36 were synonymous. Seven synonymous and five nonsynonymous mtDNA sequence changes were detected in the ND5 gene; four were novel. The 12403C,T mutation was found in both PTC and control samples. In a later study, Abu-Amero et al. (2006) sequenced the entire coding region of mitochondrial DNA for 26 MTC patients and 119 normal population controls. Of the MTC patients, 13 were sporadic, nine had MEN 2A, one had MEN 2B and three had FMTC. In 20 MTC samples, 41 nonsynonymous mutations were detected; nine were from sporadic MTC and 11 were from ...
the spore gives rise to a small prothallus, very similar to the thalloid liverwort, but seldom exceeding a quarter of an inch in any of its dimensions, and living but a short time before its vegetation is cut short by the early development of sexual organs, from the interaction of which there results a perennial plant, the fern, which in some tropical species reaches the proportions of a tree. This, the nonsexual generation, again bears spores, which in germinating develop prothalli.. In the second group of vascular cryptogams chosen for illustration (the rhizocarpex), there are two sorts of spores, - large ones, the macrospores, and small ones, the microspores. In germination they produce microscopic prothalli, which in some species result merely from the segmentation of the spores, with scarcely any increase in their size; so that the sexual generation is barely large enough to burst the wall of the spore, after doing which its career is soon terminated by the precocious development of ...

If you are pregnant, make sure you tell your healthcare professionals before you are immunized against anything. In general, pregnant women may be immunized with vaccines made from bacterial or viral noninfectious fragments, such as proteins, polysaccharides, or toxins. They may also receive vaccines made from inactive whole bacteria or viruses. However, some experts recommend against the use of immunizing agents during the first trimester to avoid febrile reactions. Live vaccines (such as for measles and chickenpox) are contraindicated due to the theoretical risk of transmitting the infection to the fetus. Reassuringly, as of yet, no vaccine (live, inactive or other) has been associated with congenital anomalies. - Uniprix

Soy milk is used as a cows milk replacer, and is marketed for the general population.18 Also, it is used as a substitute for cows milk in infant feeding formulas intended for babies who are allergic to cows milk. Soy milk is not the equivalent of milk from humans (or from cows, goats, or sheep). Soy milk has several undesirable features when used in infant feeding formulas.19 Soy can exert adverse effects on the hormonal development of infants.20,21,22 Soy milk formula is devoid of cholesterol, a vital substance for proper development of the brain and central nervous system in infants. A study of infants fed soy formula showed a concentration of estrogenic compounds as much as 22,000 times higher than those in human breast milk or in milk-based formula. This startling finding caused speculation in the New Zealand Medical Journal that such an overload of estrogen in infants might result in precocious development of breast and secondary sex characteristics in very young females. In addition, ...
Atherosclerosis (AS) is chronic inflammation in response to lipid accumulation. MicroRNA-155 (miR-155) is being increasingly studied to evaluate its potential as diagnostic biomarkers and therapeutic targets in many diseases. However, delineating the role of miR-155 in AS remains difficult. Here, we detected constitutive expression of several microRNAs (miRNAs) possibly associated with cardiovascular disease in foam cells and clinical specimens from patients with AS. Among them, we found that the level of miR-155 in foam cells was the most significantly elevated in a dose- and time-dependent manner. In addition, the expression of miR-155 was elevated in the plasma and plaque of patients with AS. We also reported for the first time that miR-155 targets calcium-regulated heat stable protein 1 (CARHSP1), which regulates the stability of tumor necrosis factor alpha (TNF-α) mRNA. Furthermore, we investigated the mechanism by which the miR-155 level is elevated. miR-155 upregulation is due to transcriptional
E. coli Source ß-Glucuronidases ß-Glucuronidase is a ~290 kDa tetrameric protein with an isoelectric point of 4.8.1 Unlike the enzyme preparations from mollusks that naturally contain ß-glucuronidase and sulfatase activities in almost equal amounts, the preparation of ß-glucuronidase from E. coli is essentially free of sulfatase activity. The enzyme from E. coli has a high rate of hydrolytic activity and it retains this activity during hydrolysis better than similar enzymes that are more sensitive to changes in the concentration of ß-glucuronide conjugates. The enzyme preparation from E. coli has been shown to be useful for determining the presence of androsterone, 17-hydroxycorticosteroids, and estriol in urine.2 The E. coli enzyme has also been shown to be more active against estrogen conjugates than other sources of the enzyme.3 Optimal pH: 6-7 References1.

Background The role of nitric oxide (NO) production, at the brain-stem level, in ventilatory control and pain perception is poorly understood. Furthermore, it is not clear whether NO synthase (NOS) inhibition can affect morphine-induced ventilatory depression or analgesia. The central hypothesis of this investigation was that NO, at supraspinal sites, can influence ventilation and nociception and can modulate the ventilatory depressant and antinociceptive actions of morphine. Using drug delivery via the fourth cerebral ventricle, the authors examined the ventilatory and nociceptive effects of an NOS inhibitor and an NO donor in the presence or absence of morphine sulfate (MS). Methods The studies were performed in awake dogs that were restrained in a stanchion using a fourth ventricle to cisterna magna perfusion system. The dogs were chronically prepared with fourth ventricle and cisterna magna guide cannulae, femoral arterial/venous catheters, and a tracheostomy. Agents were prepared in a ...
The fibrocartilaginous menisci dwell between the articular surfaces of the knee and play a central role in joint function. Damage through trauma or degenerative changes is a common orthopaedic injury, disrupts the meniscus mechanical function, and leads to the precocious development of osteoarthritis. The current standard of treatment is removal of the damaged tissue, a procedure that does not re-establish normal knee mechanics. Given the frequency of meniscal injury, a restorative repair strategy remains a major unmet need in orthopaedic medicine. With the goal of replacing damaged meniscus with engineered biologic tissue that can restore meniscal function, this work focuses on scaffolds composed of aligned biocompatible and biodegradable nanofibers that mimic the length-scale and organization of fibrous tissues. The highly ordered extracellular matrix of the meniscus is primarily composed of co-aligned collagen fibers, enabling the tissue to bear the high tensile loads seen with normal joint

In a study of the febrile responses of rabbits to repeated intravenous injections of pyrogenic substances from Eberthella typhosa, Serratia marcescens, and Pseudomonas aeruginosa, the following observations were made:. 1. A characteristic pattern of response to daily injections of the same dose of pyrogenic material was noted. This consisted of a progressive diminution in febrile response during the 1st week or 10 days, after which an animal responded to each injection with approximately the same degree of fever, even when the injections were continued for several weeks.. 2. Animals given injections of the same amount of pyrogenic material at semiweekly or weekly intervals showed some diminution in febrile reaction but the alteration was less pronounced than that in animals injected every day.. 3. Pyrogen tolerance appeared to be lost quickly. Animals allowed to rest for approximately 3 weeks reacted to readministration of pyrogen with fever comparable with that which occurred after the first ...

South Korean researchers announced they have discovered a peptide in bullfrog skin that offer anti-oxidant and antiaging properties.
Effect of altered acid-base balance, induced by the intravenous infusion of either hydrochloric acid or sodium bicarbonate, on adrenocortical function in anesthetized dogs was studied. The secretory activity of the adrenal cortex was determined by measuring 17-hydroxycorticosteroids in adrenal venous blood. Adrenocortical stimulation occurred in dogs with a profound decrease in arterial ph and bicarbonate concentration in the presence of a normal arterial CO2 tension (acid infusions) and in dogs with increased arterial CO2 tension and bicarbonate concentration in the presence of a normal arterial ph (bicarbonate infusions). It is concluded that concomitant alterations in both arterial ph and CO2 tension are not required to initiate an adrenocortical response, and it is suggested that a suitable change in either of these factors may act as a pituitary-adrenocortical stimulus.. ...
A new drug formulation of the adrenal cortex (AC) inhibitor o,p′-DDD (chloditan) was developed as a solution for i.v. injection. Its effects on glucocorticoid hormone production by human AC tissue culture and AC function in dogs were studied. A concentration range of 0.005 - 5.0 mg/mL was established by adding 5% o,p′-DDD solution to the culture medium. Cultivation of specimens of human adrenocortical tissue in the presence of o,p′-DDD solution caused after 24 h a dose-dependent decrease of 11-hydroxycorticosteroid (11-HCS) content by 11.0 - 69.8%. The 11-HCS content in dog blood plasma decreased by an average of 3.5 times; the response to synthetic 1 - 24-corticotropin stimulation, by three times, with daily administration for 3 d of 10 mL of the solution. The 11-HCS blood level was still reduced two weeks after withdrawal of the drug. The proposed o,p′-DDD solution showed adrenocorticolytic activity and could be recommended for clinical trials.
Forty-eight children received 158 infusions using one of the three regimens. Twenty-nine complications occurred in 24 children. A significant difference in the complication rate was present among the three regimens (P = 0.005). Nineteen children had minor complications, mainly febrile reaction or asymptomatic hypocalcaemia. Four major complications consisting of one seizure, one respiratory distress and two hypocalcaemic tetany were encountered, all with regimen B. Intraoperative complication faced was loss of position due to splintering of the cortex while rush rodding. This was seen in 20% of the long bone segments operated in those who received pamidronate as compared to 4.4% of the segments which were operated prior to the initiation of pamidronate therapy; the odds of splintering were 5.4 times higher for those patients who were bone segment rodded after pamidronate therapy ...
348 Treatment. Routine nursing and bed care were administered during the acute stage of the disease. Codeine sulfate, with acetyl salicylic acid, was given for relief of the severe headache, the intake of fluids was encouraged, dextrose and saline were given intravenously, and hydrotherapy was employed to combat the febrile reaction. Chemotherapy was used in a few cases but was observed to increase the toxicity of the disease. From clinical observation, it was deduced that the incubation period of this disease was from 3 to 10 days. The disease was self-limited in nature, and varied from a mild febrile illness of short duration, to a severe, debilitating, prolonged disease with a protracted convalescence.. MILITARY EXPERIENCE. At Brooke General Hospital, during the months of May and June 1943, 485 patients with the syndrome were observed, and probably nearly as many had been observed the previous year. Epidemiologically, it appeared that this disease was more severe and more prevalent in 1943 ...

Pancreatitis-associated protein (PAP) was discovered in the pancreatic juice of rats with acute pancreatitis. PAP is a 16 kDa secretory protein structurally related to the C-type lectins although classical lectin-related function has not been reported yet. Then, it was demonstrated that PAP expression may be activated in some tissues in a constitutive or injury- and inflammation-induced manner. More recently, it has been found that PAP acts as an anti-inflammatory factor in vitro and in vivo. PAP expression can be induced by several pro- and anti-inflammatory cytokines and by itself through a JAK/STAT3-dependent pathway. PAP is able to activate the expression of the anti-inflammatory factor SOCS3 through the JAK/STAT3-dependent pathway. The JAK/STAT3/SOCS3 pathway seems to be a common point between PAP and several cytokines. Therefore, it is reasonable to propose that PAP is a new anti-inflammatory cytokine.. Lire larticle ...
The relation between mechanical film properties of various adsorbed protein layers at the air/water interface and intrinsic stability of the corresponding proteins is discussed. Mechanical film properties were determined by surface deformation in shear and dilation. In shear, fracture stress, σf, and fracture strain, γf, were determined, as well as the relaxation behavior after macroscopic fracture. The dilatational measurements were performed in a Langmuir trough equipped with an infra-red reflection absorption spectroscopy (IRRAS) accessory. During compression and relaxation of the surface, the surface pressure, Π, and adsorbed amount, Γ (determined from the IRRAS spectra), were determined simultaneously. In addition, IRRAS spectra revealed information on conformational changes in terms of secondary structure. Possible correlations between macroscopic film properties and intrinsic stability of the proteins were determined and discussed in terms of molecular dimensions of single proteins ...
Panigrahy and colleagues, including Charles N. Serhan, PhD, DSc, director of the Center of Experimental Therapeutics and a member of the Department of Anesthesiology, Perioperative and Pain Medicine at Brigham and Womens Hospital, hypothesised that an early blockade of the inflammatory cascade and/or accelerating the resolution of inflammation could overcome the tumour-promoting unintended consequences of cancer surgery.. Using a well-established animal model, the scientists found that preoperative but not postoperative administration of a nonsteroidal anti-inflammatory drug called ketorolac eliminated the spread of cancer cells in multiple tumour-resection models, resulting in significantly prolonged survival.. The team also showed that preoperative administration of resolvins - naturally occurring anti-inflammatory factors produced by the human body first discovered by Serhan and colleagues at Brigham and Womens Hospital in 2002 - produced the same result.. Moreover, they found that ...
TY - JOUR. T1 - Endotoxin, TLR4 signaling and vascular inflammation. T2 - Potential therapeutic targets in cardiovascular disease. AU - Stoll, Lynn L.. AU - Denning, Gerene M.. AU - Weintraub, Neal L.. PY - 2006/11/1. Y1 - 2006/11/1. N2 - Cardiovascular disease ranks among the leading causes of morbidity and mortality in adult populations in the Western world. Significant progress in understanding the etiology of cardiovascular disease has come from recent recognition that chronic inflammation plays a key role in its development. The principal mediators of this inflammatory response, and the mechanisms by which they work, however, are incompletely understood. Moreover, the complex nature of the inflammatory response poses significant challenges to the development of effective and targeted treatments. Potentially promising targets to reduce inflammation in atherosclerosis include Toll-like receptor (TLR) pathways and anti-inflammatory factors that modulate TLR signaling. In this review, we ...
Results MiR-155 expression was significantly increased in the development of DAH. Disease progression was reduced in miR-155-/- mice and by in vivo silencing of miR-155 using miR-155 antagomir. MiR-155 silencing dampened pristane-induced ectopic activation of multiple inflammatory pathways, and reduced the expression of pro-inflammatory cytokines. Several negative regulators of nuclear factor (NF)-κB signalling were inhibited by pristane, and were re-activated in miR-155-/- mice. In particular, the anti-inflammatory factor peroxisome proliferator-activated receptor-α was identified as a direct target of miR-155. ...

The steady-state transport kinetics of the interaction between external sodium and the diuretic drug, amiloride, was studied in isolated anuran skin epithelia. We also investigated the effect of calcium on the amiloride-induced inhibition of short-circuit current (Isc) in these epithelial preparations. The major conclusions of this study are: (a) amiloride is a noncompetitive inhibitor of Na entry in bullfrog and grassfrog skin, but displays mixed inhibition in R. temporaria and the toad. A hypothesis which states that the interaction sites for amiloride and Na on the putative entry protein are spatially distinct in all of these species is proposed. (b) The stoichiometry of interaction between amiloride and the Na entry mechanism is not necessarily one-to-one. (c) The external Ca requirement for the inhibitory effect of amiloride is not absolute. Amiloride, at all concentrations, is equally effective in inhibiting Isc of bullfrog skin independently from the presence or absence of external Ca. ...
IGF-2 - promotes proliferation of many cell types primarily of fetal origin. IGF-2 is almost exclusively expressed in embryonic and neonatal tissues. Following birth, the level of detectable IGF-2 protein falls significantly. While IGF-2 may be primarily fetal in action it is also essential for development and function of organs such as the brain, liver and kidney. It also promotes tissue growth. IGF-2 is secreted by the brain, kidney, pancreas and kidney in mammals. It is more specific in action than IGF-1. TGF beta (transforming growth factor beta) - breast cancer research; stimulates significant collagen and elastin production, as well as giving supplemental support to healing factors enabling wounds to heal markedly faster. Anti-inflammatory factors also appear to be beneficially effected. Collective scientific opinion views TGF Beta as a major tool in helping to reverse the visible signs of aging.

Some patients may experience drug fever, a marked febrile response to penicillamine, usually in the second to third week following initiation of therapy. Drug fever may sometimes be accompanied by a macular cutaneous eruption. In the case of drug fever in patients with Wilsons disease or cystinuria, penicillamine should be temporarily discontinued until the reaction subsides. Then penicillamine should be reinstituted with a small dose that is gradually increased until the desired dosage is attained. Systemic steroid therapy may be necessary, and is usually helpful, in such patients in whom drug fever and rash develop several times.. In the case of drug fever in rheumatoid arthritis patients, because other treatments are available, penicillamine should be discontinued and another therapeutic alternative tried since experience indicates that the febrile reaction will recur in a very high percentage of patients upon readministration of penicillamine.. The skin and mucous membranes should be ...
Less] ABSTRACT: BACKGROUND: Obesity can be linked to disease risks such as diabetes and cardiovascular disorders, . . . [More] ABSTRACT: BACKGROUND: Obesity can be linked to disease risks such as diabetes and cardiovascular disorders, but recently, the adipose tissue (AT) macrophage also emerges as actively participating in inflammation and immune function, producing pro- and anti-inflammatory factors. Connections between the AT and chronic lung diseases, like emphysema and asthma and a protective role of adipocyte-derived proteins against acute lung injury were suggested. In this study we addressed the question, whether a diet challenge increases the inflammatory response in the alveolar and the blood compartment in response to carbon nanoparticles (CNP), as a surrogate for ambient/urban particulate air pollutants. METHODS: Mice were fed a high caloric carbohydrate-rich (CA) or a fat-rich (HF) diet for six weeks and were compared to mice kept on a purified low fat (LF) diet, respectively. ...
