background:   objective: this study was conducted to determine the effect of omega-3 supplementation on sex hormone-binding protein (shbg), testosterone, free androgen index (fai) and menstrual status in women with pcos.   materials and methods: this double-blind randomized clinical trial was conducted on 78 overweight/obese women with pcos. participants were randomized to receive omega-3 (3gr/...

In immuno-light and -electron microscopy, brain-type fatty acid binding protein (B-FABP) is localized in the sustentacular cells enclosing the chromaffin cells in the adrenal medulla. This represents another new feature commonly shared by the sustentacular cells and ganglionic satellite cells, the latter of which has already been reported to localize this molecule, and suggests a common feature...

Human serum albumin (HSA) is the most abundant protein in the blood plasma. Drug binding to HSA is crucial to study the absorption, distribution, metabolism, efficiency and bioavailability of drug molecules. In this study, isothermal titration calorimetry and molecular dynamics simulation of HSA and its complex with indometacin (IM) were performed to investigate thermodynamics parameters and th...

the effects of allopurinol, acyclovir and theophylline on the activity of adenosine deaminase (ada) were studied in 50 mm sodium phosphate buffer ph 7.5 at 27°c, using a uv– vis spectrophotometer. adenosine deaminase is inhibited by these ligands, via different types of inhibition. allopurinol, as a transition state analog of xanthine oxidase, and acyclovir competitively inhibit the catalytic a...

BACKGROUND AND OBJECTIVES: Most transgender individuals assigned female at birth use chest binding (ie, wearing a tight garment to flatten tissue for the purpose of gender expression), often beginning in adolescence, explore their identity. Although is critical mental health, negative physical side effects, ranging from chronic pain rib fractures, are common. Time first onset symptoms unknown. ...

the purpose of this study was to determine the effects of feeding iron-deficient diet during pregnancy and lactation on maternal rats. a total number of 64 rats were divided into 4 groups (pregnant), (non pregnant), (lactating) and (non lactating) with 16 animals in each group. parameters used to evaluate the effects of dietary iron deficiency on the maternal animals were: iron contents of live...

in this study at first , an azo dye, 2,7- naphthalenediol, 2-[(4-bromophenyl)azo (bpand) as a ligand has been synthesized by addition of p-bromoaniline to the modified montomorillonite k10 clay. this ligand was characterized using 1h-nmr, uv-vis and ir spectroscopies. subsequently, its interaction with calf thymus deoxyribonucleicacid ,ct-dna was investigated in 5 mm phosphate buffer solution, ...

human serum albumin (hsa) is the most abundant plasma protein in the human body. hsa plays an important role in drug transport and metabolism. this protein has a high affinity to a very wide range of materials, including metals such as cu2+ and zn2+, fatty acids, amino acids and metabolites such as bilirubin and many drug compounds. in this study, we investigated the effects of co-amoxiclav, as...

We consider the nearest-neighbour tight binding model of honeycomb lattice in magnetic fields and discover surprizing new analytical results that fully explain fractal spectra experimentally observed asymmetries density states molecular graphene. describe a Cantor spectrum for irrational flux through honeycomb, establish existence zero energy Dirac cones each rational with explicit estimates on...
