During mitosis, molecular motors hydrolyze ATP to generate sliding forces between adjacent microtubules and form the bipolar mitotic spindle. Lansky et al. now show that the diffusible microtubule crosslinker Ase1p can generate sliding forces between adjacent microtubules, and it does so without ATP hydrolysis.

The current study presents an effective and simple strategy to obtain stable porous scaffolds from gelatin via a gas foaming method. The technique exploits the intrinsic foaming ability of gelatin in the presence of CO2 to obtain a porous structure stabilised with glutaraldehyde. The produced scaffolds were characterised using physical and mechanical characterisation methods. The results showed...

core-shell 12-tungstophosphoric acid/tio2 (hpw/tio2) nanoparticles at 10 and 20% of hpw have been synthesized by simple in-situ sol- gel method. characterization of the samples was carried out by x-ray diffraction (xrd), scanning electron microscopy (sem), fourier transform infrared (ftir). the x-ray diffraction patterns of as prepared solid samples, indicated characteristic peaks of titania wi...

In this work, we synthesized a chitosan-activated carbon composite (Cs–C) using sodium tripolyphosphate (STTP) as crosslinker and it was evaluated for the adsorptive removal of RBBR dye showing excellent capacity 540.3 mg g −1 .

A novel dual-curable blocked isocyanate crosslinker was designed for the simultaneous radical and urethane crosslinking of automotive clearcoats under low-temperature conditions. Three groups on three ends hexamethylene diisocyanate-based were using two different blocking agents: a thermal initiator (TRI) dimethyl pyrazole. Clearcoats based hydroxyl-functionalized methacrylate oligomer resin hy...

Abstract In order to improve the temperature and shear resistance of fracturing fluid, a kind nano-zirconium-boron crosslinker, which is different from traditional zicral-boron prepared using 4wt% borax, 50 v/v% glycerol, 8 triethanolamine 40 v/v % acetylacetone as raw materials, its chemical structure characterized by infrared spectroscopy performance, such viscoelasticity, gel breaking proper...

The aims of this study was to determine the effect of organic and inorganic Zn and Cu supplements on performance, footpad dermatitis (FPD), carcass characteristics and blood profile in broiler chickens. A total of 336 one-day-old Ross 308 broiler chicks were distributed into 24 floor pen and reared for 42 days. A basal mineral premix (without Zn and Cu) was supplemented with organic or inorgani...

Although soluble oligomers are regarded as the most toxic aggregates of Abeta, the amyloidogenic nature of Abeta certainly is not accidental and should play a role in the still unknown physiological functions of Abeta. The testable hypothesis put forward here postulates that short Abeta oligomers can crosslink the neurotrophin receptor p75 with APP and other proteins and mediate a direct cooper...

Chitosan has high biocompatibility, supports proliferation of many cells, and can be a good carrier for various growth factors. However, low attachment ratio spheroid formation several stem cell types on plain chitosan scaffolds/films is still problem. In this study, it was aimed to obtain 3D scaffolds using medical grade (MC) with deacetylation degree (DD ≥ 92.6%) overcome the rat adipose tiss...
