TNF Inhibitors

TNF inhibitors are a group of medications used worldwide to treat inflammatory conditions such as rheumatoid arthritis (RA) psoriatic arthritis juvenile arthritis inflammatory bowel disease (Crohn's and ulcerative colitis) ankylosing spondylitis and psoriasis They reduce inflammation and can stop disease progression by targeting an inflammation-causing substance called Tumor

Antithyroid Medications for Hyperthyroidism

Antithyroid medications—sometimes written as anti-thyroid medications—are a common treatment for hyperthyroidism particularly if you have an ongoing form of hyperthyroidism caused by Graves' disease or a goiter The goal of antithyroid medications is to prevent the thyroid from producing excess amounts of hormone

Assessing Physicochemical Properties of Drug Molecules via

In other words the variability in the physicochemical properties of the 7-substituted derivatives arises due to steric effects which in turn influence the solvent binding motif The strong correlations that we observe for the 5- and 6-substituted species on the other hand demonstrate that DMS ion–solvent clustering measurements are

Effects of Clay Content on the Properties of Nanocomposite

For two different types of poly(N-isopropylacrylamide) (PNIPA) hydrogels i e nanocomposite type PNIPA hydrogels (NC gel) and conventional chemically cross-linked PNIPA hydrogels (OR gel) the effects of cross-linker contents on various physical properties were investigated In NC gels composed of a unique organic (PNIPA)/inorganic (clay) network the inorganic clay acts


Physicochemical definition is - being physical and chemical Recent Examples on the Web To tackle this problem researchers at the RIKEN Center for Biosystems Dynamics Research identified a gel that closely mimics the physicochemical properties of organs that have undergone the tissue clearing process — Dennis Normile Science | AAAS Mouse brains

Effect of reducing agents on physicochemical properties

Dec 10 2004Effects of different reducing agents (cysteine ascorbic acid and sodium bisulfite) at various levels on physicochemical properties of protein transglutaminase activity and gel properties of surimi produced from frozen croaker lizardfish threadfin bream and bigeye snapper were studied Addition of cysteine resulted in the highest increase in the breaking force and

Effect of Capping Agent on Physicochemical Properties of

Nanoscale zinc substituted hydroxyapatite has been synthesized by solgel technique at 70 C using an aqueous solution of calcium nitrate tetrahydrate (CNT) zinc nitrate tetrahydrate (ZNT) and potassium dihydrogen phosphate (KDP) as starting materials with or without a capping agent triethanolamine (TEA) The synthesized nanopowders were calcined at two temperatures 800

Effects of the physicochemical properties of titanium

Until now the potential effects of titanium dioxide (TiO 2) nanoparticles on endothelial cells are not well understood despite their already wide usage Therefore the present work characterizes six TiO 2 nanoparticle samples in the size range of 19 17 to 87 13 nm which are commonly present in sun protection agents with respect to their physicochemical properties (size

Pharmacology of anaesthetic agents II: inhalation

Volatile anaesthetics exert their effects at multiple sites throughout the central nervous system It appears that volatile agents preferentially potentiate GABA A receptors and two-pore domain K + channels whereas the anaesthetic gases nitrous oxide and xenon inhibit N-methyl-d-aspartate channels Uptake and removal of inhalation agents from the body depends on the alveolar
