Interview and observation were used in collecting the needed data at selected craft centres in the Kwabre East District, Ejisu-Juaben municipality, Kumasi sub-metro and metropolitan in the Ashanti region of Ghana. The study employed both descriptive and experimental research methods based on the qualitative research approach. It was revealed that Kente and Adinkra enjoy wide reputation and therefore are considered as prestigious clothes. However, Nwomu cloth does not have this fame, only indigenes understand its usage and the philosophy behind its production. In view of this, it is recommended that the elders who are endowed with this unique craft must open their doors to the youth to learn the craft.展开更多

Methods Neonatal rat cardiomyocytes were cultured from the ventricles of l-day-old Wistar rats. Cells were exposed to different concentrations of salubrinal (10, 20, and 40 gmol/L) for 30 min followed by TM treatment or hypoxia for 36 h. Apoptosis was measured by a multiparameter HCS (high content screening) apoptosis assay, TUNEL assay and flow cytometry. The phosphorylation of eukaryotic translation initiation factor 2 subunit alpha (eIF2c0 and the expression of cleaved caspase-12 were determined by Western blotting. C/EBP homologous protein (CHOP) was detected by immunocytochemistry. Results HCS, TUNEL assays and flow cytometry showed that salubrinal protected cardiomyocytes against apoptosis induced by TM or hypoxia. Western blotting showed that salubrinal protected cardiomyocytes against apoptosis by inducing eIF2ct phosphorylation and down-regulating the expression of the endoplasmic reticulum stress-mediated apoptotic proteins, CHOP and cleaved caspase-12. Conclusions Our study suggests that salubrinal protects rat cardiomyocytes against TM- or hypoxia-associated apoptosis via a mechanism involving the inhibition of ER stress-mediated apoptosis.展开更多

The mature virion comprises 11 dsRNA genomes enclosed by two concentric icosahedral proteins shells that is comprised of five core proteins and two outer capsid proteins. The genome sequence and 3D structure demonstrate there is a higher level of sequence homology in structural proteins between GCRV and mammalian orthoreoviruses (MRV) compared to other members of the family. To understand the pathogenesis of GCRV infection, the outer capsid protein VP5, a homology of the μ1 protein of MRV, was expressed in E.coli. It was found that the recombinant VP5 was highly expressed, and the expressed His-tag fusion protein was involved in the formation of the inclusion body. Additionally, specific anti-VP5 serum was prepared from purified protein and western blot demonstrated that the expressed protein was able to bind immunologically to rabbit anti GCRV particle serum and the immunogenicity was determined by ELISA assay. Additional experiments in investigating the functional properties of VP5 will further elucidate the role of the GCRV outer capsid protein VP5 during entry into host cells, and its interaction among viral proteins and host cells during the infection process.展开更多

The author thinks that the best choice is to recycle by seller. At present, it should be encouraged that seller, who are at dominant position in the supply chain, to carry out recycling old clothing so as to lead the other members in the supply chain to participate in recycling. Meanwhile, establish the corresponding legal provisions for the recycling of discarded clothing.展开更多

VOCs removal from raw water is an important task for waterworks to guarantee drinking water security. The removal of VOCs such as chlorobenzene (CB) and ethylbenzene (EB) from raw water by air stripping was investigated under various conditions, inciuding the variation of temperature (5-30~C), pH (3.5-10.5), and air/water ratio (10-60). The air stripping removal efficiency of VOCs decreased with VOCs concentration declining in water. And Henry's law constant was demonstrated as an indicator of the estimation of VOCs removal efficiency for air stripping. The effects of temperature and the ratio of air and water were found to play a great role in VOCs removal, but the effect of pH seemed to be negligible. This study demonstrates that air stripping provides a promising opportunity in removing VOCs in drinking water treatment, especially for the relatively high concentration of VOCs.展开更多
