The plasma membrane glycoprotein receptor CD163 is a member of the scavenger receptor cystein-rich (SRCR) superfamily class B that is highly expressed on resident tissue macrophages in vivo. Previously, the molecule has been shown to act as a receptor for hemoglobin-haptoglobin complexes and to mediate cell-cell interactions between macrophages and developing erythroblasts in erythroblastic isl...

The use of protective agents (e.g., sulfhydryl compounds, certain vitamins, amino acids, cations, and antibiotics) offers a novel and promising means of dealing with the ever increasing burden of environmental hazards facing man. Through the daily uptake of minimal doses as a prophylactic measure by the most endangered groups of the population or by direct mixing of the appropriate protective a...

Protease inhibitors represent a major class of drugs, even though a large number of proteases remain unexplored. Consequently, a great interest lies in the identification of highly sensitive substrates useful for both the characterization and the validation of these enzyme targets and for the design of inhibitors as potential therapeutic agents through high-throughput screening (HTS). With this...

Cadmium (Cd) is a nonessential microelement and low concentration Cd2+ has strong toxicity to plant growth. Plant metallothioneins, a class of low molecular, cystein(Cys)-rich and heavy-metal binding proteins, play an important role in both metal chaperoning and scavenging of reactive oxygen species (ROS) with their large number of cysteine residues and therefore, protect plants from oxidative ...

The use of cephalosporin antibiotics in veterinary practice is likely to play an important role in the development of β-lactam-resistant bacteria. To detect off-label cephalosporin antibiotic usage, an analytical method is needed that, besides the native compound, also detects their active metabolites. In this paper, the applicability of three approaches for the quantitative analysis of ceftiof...

Granulins are a group of highly conserved growth factors that have been described from variety of some organisms spanning the metazoan. It has been shown to have roles in multiple processes involved in cell growth, development inflammation, wound healing and tissue remodeling. In the present study, we isolated the full-length cDNA encoding Nile tilapia granulin gene by in silico cloning and 5iR...

Embryonic diapause is the reversible arrest of embryo development prior to implantation under a regime of uterine control that is not well understood. Our objective was to explore uterine modifications associated with the emergence of embryonic diapause in the mink, a species in which embryonic diapause characterizes every gestation. We investigated the uterine transcriptome at reactivation usi...

Withaferin A (WFA) is known as a constituent of Ayurvedic medicinal plant, Withania somnifera, and has been used for thousands of years. Although WFA has been used for the treatment of osteoarthritis (OA) and has a wide range of biochemical and pharmacologic activities, there are no findings suggesting its properties on chondrocytes or cartilage. The aim of the present study is to investigate t...

Sulfate-rich mine water must be treated before it is released into natural water bodies. We tested ethanol as substrate in bioreactors designed for biological sulfate removal from mine water containing up to 9 g L-1 sulfate, using granular sludge from an industrial waste water treatment plant as inoculum. The pH, redox potential, and sulfate and sulfide concentrations were measured twice a week...

Bio-fuel produced from ethanol is economically and environmentally advantageous in context of changing global climate. A large number of microorganisms are capable of cellulase production but most of them cannot be utilized commercially due to their low activity. In the present study, an effiecient cellulose degrading strain of Bacillus pumilus was obtained after thorough screening for the prod...
