As part of an educational exercise designed to introduce school students the technique single-crystal X-ray diffraction and enhance their understanding primary secondary bonding, a group nine was given opportunity prepare new compounds solve refine data collected on crystalline materials they had prepared. Their investigation alkali metal salts 4-hydroxybenzoic acid (H 2 hba) yielded structures...

BACKGROUND Cases of Frontotemporal Lobar Degeneration (FTLD) and Motor Neurone Disease (MND) associated with expansions in C9ORF72 gene are characterised pathologically by the presence of TDP-43 negative, but p62 positive, inclusions in granule cells of the cerebellum and in cells of dentate gyrus and area CA4 of the hippocampus. RESULTS We screened 84 cases of pathologically confirmed FTLD a...

Dietry flavonoids(Poly phenols) are important phytonutrient component widely distributed in plant foods , flavonoids have beneficial biological activities,such as antioxidant activity can chelate with metal ions the interaction of lead(׀׀) ion a poly hydroxylated flavonoids, quercetin molecule,were investigated electrochemically acidic media .The Differential Puls Polarographic Techanique was u...

Theodorakis, Nicholas G., and Antonio De Maio. Cx32 mRNA in rat liver: effects of inflammation on poly(A) tail distribution and mRNA degradation. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1249–R1257, 1999.—Previous studies showed that the expression of connexin 32 (Cx32), the polypeptide subunit component of the major hepatic gap junction, is reduced in liver by changes i...

APLF is a novel protein of unknown function that accumulates at sites of chromosomal DNA strand breakage via forkhead-associated (FHA) domain-mediated interactions with XRCC1 and XRCC4. APLF can also accumulate at sites of chromosomal DNA strand breaks independently of the FHA domain via an unidentified mechanism that requires a highly conserved C-terminal tandem zinc finger domain. Here, we sh...

Two structurally and immunologically distinct species of nuclear polyadenylate [poly(A)] polymerases have been characterized. One of these enzymes is relatively absent in normal tissues but is predominant in primary and transplanted tumors and transformed cell lines. The presence of the tumor type enzyme in fetal liver, but not in regenerating liver, suggests that it is an oncofetal protein. An...

We report on multilayer layer-by-layer (LbL) films of the conjugated polymer sodium poly[2-(3-thienyl)ethyloxy-4-butylsulfonate] (PTH) assembled with polycations: poly(diallyldimethylammonium chloride) (PDDA), 20% quaternized poly(N-ethyl-4-vinylpyridinium bromide) (Q20), poly(ethylene imine) (PEI), and poly(allylamine hydrochloride) (PAH). These films were prepared through spin-assisted LbL as...

in this study, microspheres containing estradiol valerate were prepared by solvent evaporation method using poly (glycolide-co-lactide) (plga 50:50) and poly (lactide). the effect of different process variables such as polymer type, drugpolymer ratio, stirring rate, volume of internal phase and temperature of external phase on the morphology, particle size distribution, encapsulation efficiency...

peripheral nerve injuries caused by traffic accidents, resections of tumors or iatrogenic side effects of the surgeries are few of the most common form of trauma occurring with up to 500,000 cases each year in iran. conventional strategies including nerve coaptation, and the application of autografts, allografts and xenografts are restricted due to the limited availability of donors, immune-rej...
