Proteins are complex macromolecules that evolved over billions of years to be active in aqueous solution. Water is a key element that stabilizes their structure, and most structural studies on proteins have thus been carried out in aqueous environment. However, recent experimental approaches have opened the possibility to gain structural information on proteins from gas-phase measurements. The ...

Psoriasis is a chronic, relapsing, inflammatory and hyperproliferative skin disorder. The levels of acute phase proteins are suggested to be elevated in those patients with acute disease. The expression of selected acute phase proteins as the parameters of humoral immunity has been analyzed in 70 patients with acute psoriasis and 40 healthy controls. The aim was to evaluate the inflammatory res...

The high mobility group (HMG) of nonhistone proteins have been investigated using two high performance liquid chromatographic techniques (HPLC). Reversed-phase HPLC under conditions of 50 mM triethylamine adjusted to pH 2.2 with phosphoric acid (solvent A) and 95% acetonitrile in water (solvent B) was used to separate proteins primarily on the basis of differences in the overall hydrophobi...

An extensible semiflexible filament moving on a motility assay of motor proteins undergoes first order re-entrant phase transition from open chain to spiral as function the extension rate and turnover proteins.

objective(s)the aim of this study was to evaluate plasma levels of nitric oxide (no) and certain acute phase proteins(caeruloplasmin, transferrin, haptoglobin, c-reactive protein) in nigerian subjects after short and prolonged exercises.materials and methodsa total of 57 subjects (34 males and 23 females) between ages of 19 and 45 years participated in this study and weredivided into three grou...

keeping constant all agronomic factors except temperature is a way to follow heat shock proteins (hsps) expression. three different sunflower hybrids derived from the cross between an inbred line, cms ha 89, and three different restorer inbred lines, with resistance, susceptible, and normal reactions to drought, were produced. in order to investigate the impact of temperature on protein accumul...
