In the highly competitive market of fuel cells, solid alkaline fuel cells using liquid fuel (such as cheap, non-toxic and non-valorized glycerol) and not requiring noble metal as catalyst seem quite promising. One of the main hurdles for emergence of such a technology is the development of a hydroxide-conducting membrane characterized by both high conductivity and low fuel permeability. Plasma ...
In order to develop the usefulness of Fanconi's anemia (FA) lymphoblast lines for biochemical and genetic studies, we have determined their sensitivity to a variety of DNA-damaging chemicals. We have adapted a growth inhibiton protocol in which the sensitivity of a cell line is characterized by the drug concentration yielding a 50% inhibiton of growth (EC50). The DNA-cross-linking agents, mitom...
Carnosine is an endogenous free-radical scavenger. The latest research has indicated that apart from the function of protecting cells from oxidation-induced stress damage, carnosine appears to be able to extend the lifespan of cultured cells, rejuvenate senescent cells, inhibit the toxic effects of amyloid peptide (A beta), malondialdehyde, and hypochlorite to cells, inhibit glycosylation of pr...
Abstract In the drilling industry, demand for environmentally friendly additives with high thermal stability is increasing due to dual factors of environmental pressure and high-temperature oil layers. However, commonly used non-toxic biodegradable additives, such as etherified modified starch, cannot withstand temperatures higher than 150 °C. Additionally, natural polymers better obtained thro...
Understanding the organization and mechanical function of the extracellular matrix (ECM) is critical for the development of therapeutic strategies that regulate wound healing following disease or injury. However, these relationships are challenging to elucidate during remodeling following myocardial infarction (MI) due to rapid changes in cellularity and an inability to characterize both ECM mi...
The way of making cross-linkable polyethylene through silane grafting has gained much attention in recentyears because of its various advantages such as easy processing, low cost and capital investment andfavorable properties in the processed materials. This work deals with silane grafting and moisture crosslinkingof linear low density polyethylene (LLDPE). The grafting reaction was performed i...
Assembly of spliceosomes involves a number of sequential steps in which small nuclear ribonucleoprotein particles (snRNPs) and some non-snRNP proteins recognize the splice site sequences and undergo various conformational rearrangements. A number of important intermolecular RNA-RNA duplexes are formed transiently during the process of splice site recognition. Various steps in the assembly pathw...
The easiest route to form compounds with P–Csp3–N linkage(s) is phosphorus-based Mannich-type reactions (phospha-Mannich reactions) between phosphines (R3P, R2PH, RPH2, PH3), carbonyl (mainly CH2O) and amines (R2NH, RNH2, NH3). Because of toxicity inflammability, applications PH3 its liquid analog (Me3Si)3P in such are rare. Stable, less toxic, non-pyrophoric adducts CH2O, i.e., tris(hydroxymet...
