Latest Research News on Immobilization : Dec 2021

Immobilization of Enzymes and Cells The technology for immobilization of cells and enzymes evolved steadily for the first 25 years of its existence (1), but in recent years it has reached a plateau, if not a slight decline. However, the expansion of biotechnology, and the expected developments that will accrue from advances in genetic technology,…

Latest Research News on Filamentous : Dec 2021

Filamentous growth of carbon through benzene decomposition Carbon fibres have been prepared by pyrolysing a mixture of benzene and hydrogen at about 1100°C. They have been studied by high resolution electron microscopy. These fibres have various external shapes and contain a hollow tube with a diameter ranging from 20 to more than 500 Å along…

Latest Research News on Collagenase : Dec 2021

Collagenase production by human skin fibroblasts Normal human skin fibroblasts, when cultured in serum free medium, produce collagenase in an inactive form. The enzyme in the crude medium can be activated by a brief preincubation with trypsin or by autoactivation. Once activated, the fibroblast collagenase is identical in its mechanism of action to human skin…

Latest Research News on Receptor Genes : Dec 2021

Identification of a Family of Muscarinic Acetylcholine Receptor Genes Complementary DNAs for three different muscarinic acetylcholine receptors were isolated from a rat cerebral cortex library, and the cloned receptors were expressed in mammalian cells. Analysis of human and rat genomic clones indicates that there are at least four functional muscarinic receptor genes and that these…

Latest Research News on lactamases : Dec 2021

The structure of β-lactamases The β-lactamases are widely distributed in both Gram-positive and Gram-negative bacteria. They all inactivate penicillins and cephalosporins by opening the β-lactam ring. Many varieties of the enzyme can be distinguished on the basis of their catalytic and molecular properties, but only amino acid sequence determination gives information upon which a molecular…

Latest Research News on Amylase Production : Dec 2021

Optimization of α-amylase production by Bacillus sp. using response surface methodology The combined effects of macronutrients of media on α-amylase production by Bacillus sp. were studied using response surface methodology. A 22 full-factorial central composite design was chosen to explain four medium constituents, viz. starch, glycerol, yeast extract (YE) and peptone, and to analysis of…

Latest Research News on Shock Proteins : Dec 2021

Heat shock proteins and the immune response Heat shock proteins (HSPs) or stress proteins are produced by prokaryotic and eukaryotic cells in response to a variety of insults. After this original definition, it has become increasingly clear that HSPs can modify the function and destiny of other proteins and thus play an important role in…

Latest Research News on pharmacogenomics : Dec 2021

Pharmacogenomics in the clinic After decades of discovery, inherited variations have been identified in approximately 20 genes that affect about 80 medications and are actionable in the clinic. And some somatically acquired genetic variants direct the choice of ‘targeted’ anticancer drugs for individual patients. Current efforts that focus on the processes required to appropriately act…

Latest Research News on lipids : Dec 2021

The Lipids This chapter reviews the structural characteristics, biosynthesis and functions of lipids in fish. The five different types of lipid classes are: triacylglycerols, wax esters, phosphoglycerides, sphingolipids, and sterols. With the exception of cholesterol, all of the aforementioned lipid classes contain fatty acids, esterified to alcohol groups in the case of the glycerides and…
