Dispersion of objects in a fluid phase can be classified as solutions (Gibbs free energy mixing, ?Gmix < 0) or suspensions (?Gmix > depending on their thermodynamic stability. Small tend to form solutions, larger ones suspensions, e.g., molecules versus micrometer-sized colloids. Proteins and nanomaterials fall between these two size regimes. The long-standing issue whether proteins nanoparticl...

introduction: nucleolar organizer region associated proteins are a group of non histone proteins which act in r-dna transcription and r-rna processing. the amount of these proteins increase in transition from g1 to s phase in cell cycle. hence these proteins can show the proliferative index of the cells. material & methods: for this purpose 40 patients (30 gastritis, 10 carcinoma) with average ...

background the mutations of lhbs in pre-s, especially in pre-s2, are definitive in hepatocellular carcinoma (hcc) associated with hbv. however, the mechanisms of the n-glycosylation modification in lhbs are unclear. the n-glycosylation modification of lhbs affects endoplasmic reticulum stress, cell proliferation and its secretion which was further studied. objectives the objectives of our studi...

Background/Objective: Development of a new enzyme-linked immunosorbent assay (ELISA) for screening human blood serum and plasma for antibodies to human immunodeficiency virus type 1 (HIV1) and type 2 (HIV2) as HIV1/2REC ELISA diagnostic kit based on E. coli derived soluble recombinant proteins. Methods: Polypeptides corresponding to HIV1 gp41 and HIV2 gp36 immunodominant regions and HIV1 gag we...

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 hydrophobicity....

Saline Mussels Cooking Wastewater was valorised to produce PHA with Mixed Microbial Cultures (MMC). Due the high protein content (1.8–5.7 g CODPROT/L), accumulating capacity below 10%, so several strategies were tested. In acidification unit, Na(HCO3) added, increasing conversion into Volatile Fatty Acids (VFA) from 10.3% 69.2% and subsequent accumulation 6.9 14.7%. enrichment incorporation of ...

Alpha-1-proteinase inhibitor (API) is one of the acute phase proteins. Following an inflammatory stimuli the concentration of API increased up to four folds. Accompanying these quantitative changes, there is qualitative alterations in the structure of carbohydrate moiety (glycosylation). To determine the alterations in the glycosylation of API in inflammation, API was isolated from the sera of...

seed protein quality is an important topic in the production of soybean. the quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. in this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using sds-page and scanning densitometry. the results showed that seed storage protein ba...
