When hydroquinone-O,Ooffiacetic acid is used as a linker arm in solid phase oligonucleotide synthesis, the time for NH4OH cleavage of oligodeoxy- or oligoribonucleotides is reduced to only 2 min. This allows increased productivity on automated DNA synthesizers without requiring any other modifications to existing reagents or synthesis and deprotection methods. The Q-linker may also be rapidly c...

the present study deals with the oral supplementation with (50, 100 and 150 ?g/ml) synergetic effect of potassium and magnesium chloride on the fat body glycogen, protein, total lipids and haemolymph trehalose, protein of fifth instar larvae of bombyx mori l (lepidoptera: bombycidae). the observed parameters significantly increased in all the treated groups when compared with those of the corre...

introduction: aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. aluminum ions in the brain cause serious problems such as alzheimer, parkinson and other degenerative diseases. on the other hand, zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates with ...

hormone-independent prostate cancer cell lines are resistant to antineoplastic drugs, this study sought to determine the usefulness of lithium chloride as an inhibitor of glycogen synthase kinase-3β to increase the cytotoxic effect of doxorubicin, etoposide or vinblastine antineoplastic drugs on du145 cells. combination effect was assessed by using low and ic50 doses of drugs + lithium chloride...

Solution combustion was employed to create a series of ZrO2:Dy3+ (1-11 mol percent) nanoparticles (NPs) using oxalyl dihydrazide (ODH) as the fuel. NPs were subjected calcination at about 700°C. comprised 1 11 mol% Dy3+ characterized by employing X-ray diffraction (XRD), transmission electron microscopic (TEM), UV-visible, and photoelectron spectroscopic (XPS) techniques. The crystallite diamet...

Introduction In Tunisia the genus Lathyrus is represented by 15 native species , distributed essentially in marginal environments in the north of the country. Many of them are of considerable agronomic interest as forage (L. ochrus and L. articulatus) and as human food (L. cicera and L. sativus). These species are under utilised and in the past little effort has been made to expand the selectio...
