Amino acid substitutions within or near the active site of the viral neuraminidase (NA) may affect influenza virus fitness. In influenza A(H3N2) and B viruses circulating in Thailand between 2010 and 2015, we identified several NA substitutions that were previously reported to be associated with reduced inhibition by NA inhibitors (NAIs). To study the effect of these substitutions on the enzyma...

Although genetic transformation of clonally propagated crops has been widely studied as a tool for crop improvement and as a vital part of the development of functional genomics resources, there has been no report of any existing Agrobacterium-mediated transformation of yam (Dioscorea spp.) with evidence of stable integration of T-DNA. Yam is an important crop in the tropics and subtropics prov...

An investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (Dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (Curcuma longa) rhizomes under storage. Harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?C t...

The objective of this study was to investigate the therapeutic efficacies of crude yam (Dioscorea batatas) powder (PY), water extract of yam (EY), and allantoin (the active constituent of yam) in streptozotocin (STZ)-induced diabetic rats with respect to glucose, insulin, glucagon-like peptide-1 (GLP-1), C-peptide, glycated hemoglobin (HbAlc), lipid metabolism, and oxidative stress. For this pu...

The sources of energy used in cooking in most Nigeria homes are fossil fuel and biomass. The fuel is becoming expensive beyond the reach of common person. There is need to source for suitable alternative. Therefore, the work focused on use of solar cooker for cooking some staple food in Nigeria. Preliminary study was carried out to quantify appropriate water requirements for cooking some staple...

Abstract Ice cream is a frozen food product made from milk with added sweetener. The addition of purple yam and mangosteen peel extract powder has the potential to enhance product’s nutritional compounds. Purple have high antioxidant content. research aims find out best formulation ice on physical sensory properties, activity, anthocyanin This method used formulations different concentrations t...

The individual and effects of interaction of nature (X) and concentration (Y) of disintegrant and the relative density (Z) on the mechanical and release properties of chloroquine phosphate tablets were studied using a 2 factorial experimental design. Water yam starch (“low” level) and corn starch (“high” level) were used as disintegrants at concentrations of 5.0% and 20.0% w/w. The mechanical p...
