The effect of HbA and HbF on both the aggregation and deaggregation of deoxy HbS and deoxy HbCHarlem in concentrated phosphate buffers was studied by a turbidimetric method. Although pure deoxy HbA is fully soluble in 2.4 M potassium phosphate buffer, the same concentration of deoxy HbAS was insoluble in the same buffer. Since there was little dissolved hemoglobin in the solute of a mixture of ...

INTRODUCTION Although the prevalence of hepatitis virus infections in Pakistan is still unknown, limited data indicate that the exposure rate to HBV is 35-38% with 4% being carriers and 32% having anti-HBV surface antibodies through natural conversion [1, 2, 3]. Studies in Pakistan have shown that the prevalence rate of HCV is 4.8-14% for, and that it is continuously increasing. Hence there is ...

Recently, hybrid band communications have received much attention to fulfil the exponentially growing user demands in next-generation communication networks. Still, determining best communicate over is a challenging issue, especially dynamic channel conditions multi-band wireless systems. In this paper, we manipulate practical online-learning-based solution for band/channel selection radio freq...

To study the inhibitory effects of plasmid-derived small interfering RNA (siRNA) and synthetic siRNA on the expression of the hepatitis B virus surface (HBs) gene, three plasmid-derived siRNAs and one synthetic siRNA that complement the coding region of the HBs gene were prepared. The HBs expression plasmid pHBs-EGFP was also constructed. HeLa cells were co-transfected with pHBs-EGFP and the ab...
