halophilic bacteria grow over a wide range of salt concentrations. in this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. a total of 50 water, sediments and soil samples were collected from maharlu salt lake in southern region of fars-iran and subjected for isolation of the bioactive compound producing ...

Glycoprotein gp130, found on the plasma membrane of Dictyostelium discoideum amoebae, was postulated previously to play a role in phagocytosis. The gene for gp130 was cloned and when translated, yielded a 768 amino acid preproprotein of 85.3 kDa. It had nearly 40% similarity to the 138 kDa family of glycoproteins implicated in sexual cell fusion during macrocyst formation in D. discoideum. The ...

Initial contact between herpesviruses and host cells is mediated by virion envelope glycoproteins which bind to cellular receptors. In several alphaherpesviruses, the nonessential glycoprotein gC has been found to interact with cell surface proteoglycans, whereas the essential glycoprotein gD is involved in stable secondary attachment. In addition, gD is necessary for penetration, which involve...

The purpose of the present study was to explore the utility of sandwich-cultured rat hepatocytes as an in vitro tool to examine drug interactions at the hepatic transport level. Rhodamine 123 was used as a model substrate for P-glycoprotein-mediated biliary excretion. Effects of various types of P-glycoprotein modulation on the biliary excretion index (BEI; a relative measure of the extent of b...

Biomarkers facilitating both pathogen-independent diagnosis of respiratory health and breeding selection of pigs with increased resistance to respiratory tract infections would be of considerable interest to the pig industry. Following this concept we performed a comparative glycoproteome analysis of bronchoalveolar lavage fluid (BALF) from healthy pigs and pigs 4 days (acute) and 20 days (chro...

BACKGROUND Vitamin D deficiency is a common finding in obese subjects even before any bariatric operation. However, most previous studies reporting on high rates of vitamin D deficiency in obese subjects have not systematically controlled for seasonal variations. Furthermore, the existence of seasonal variation in serum 25-hydroxyvitamin D(3) levels has not been well documented in obese subject...

Background: The effect of season on vitamin D status is often overlooked in studies of optimal vitamin D concentrations and in

B virus diagnosis presents a challenge largely complicated by the asymptomatic infection of rhesus macaques, and extremely pathogenic fatal infections in humans. Humoral detection of antibodies is generally performed using whole virus antigen for which preparation requires strict biosafety measures and specialized BSL-4 facilities. As an alternative to utilizing B virus antigen, we describe the...

The objective of this study was to determine the effect of increased vitamin D fortification (250 IU/serving) of high-temperature, short-time (HTST)-processed 2% fat milk, UHT-processed 2% fat chocolate milk, and low-fat strawberry yogurt on the sensory characteristics and stability of vitamin D during processing and storage. Three replicates of HTST pasteurized 2% fat milk, UHT pasteurized 2% ...

concanavalin A-binding proteins are relatively unaffected by the changes in glucose concentration. At this threshold level of glucose the glucose-regulated proteins of Shui et al. (1977) are not apparent. The reappearance of the 100000-mol.wt. glycoprotein can be correlated with the reappearance of the 95 000-mol.wt. glucosamine-labelled glycoprotein (Fig. 2) and there seems, therefore, good re...
