Scaffolds prepared from biodegradable polyurethanes (PUR) have been investigated as a supportive matrix and delivery system for skin, cardiovascular, and bone tissue engineering. While previous studies have suggested that PUR scaffolds are biocompatible and moderately osteoconductive, the effects of encapsulated osteoinductive molecules, such as recombinant human bone morphogenetic protein (rhB...

We examined more than 700 DNA sequences (full length chromosomes and plasmids) for stretches of purines (R) or pyrimidines (Y) and alternating YR stretches; such regions will likely adopt structures which are different from the canonical B-form. Since one turn of the DNA helix is roughly 10 bp, we measured the fraction of each genome which contains purine (or pyrimidine) tracts of lengths of 10...

The mouse vascular smooth muscle α-actin (SMA) gene enhancer is activated in fibroblasts by TGFβ1, a potent mediator of myofibroblast differentiation and wound healing. The SMA enhancer contains tandem sites for the Sp1 transcriptional activator protein and Purα and β repressor proteins. We have examined dynamic interplay between these divergent proteins to identify checkpoints for possible con...

We present a simple method for describing the influence of variable attenuation of spectral irradiance, Kd(λ), on water-column photosynthesis and its inhibition by ultraviolet radiation (UV). The approach is based on weighted water transparency, a calculation introduced by Vincent et al. 1998 (Ann Glaciol 27:691–696). Key results of a depthand spectrally-resolved model of photosynthesis can be ...

Postpartum urinary retention (PUR) is defined as inability to void after six hours from delivery or having abnormal post-void residual volume (PVRV). Overt PUR easily detectable condition but covert usually remains undiagnosed. We aim investigate the incidence of and identify risk factors. A retrospective analysis postpartum women was undertaken between January-July 2016. PVRV patients either d...

Semantan (Gigantochloa scortechinii) and beting levis) bamboo are the two Malaysian that suitable to be converted into laminated boards. One of main criteria for board is its good bondability, which determined by shear performance. The performance influenced several factors such as species used, adhesive types lamination configurations. Therefore, in this study, boards were produced using Betin...
