Purpose: This study was designed to explore the nutritional (proximate, mineral, vitamin) and antinutritional compositions of Synsepalumdulcificum seeds.Method: proximate, vitamin were evaluated inSynsepalum dulcificum seeds using standard procedures.Results: Proximate composition showed moisture content (44.30 ± 0.26%), ash (1.44 0.14%), crude fat (1.33 0.58%), fibre (1.30 protein (12.32 0.10%...

When purified dimers of hemagglutinin-neuraminidase molecules released by protease digestion from three strains of human parainfluenza virus 1 were used in crystallization trials, long thin needle crystals formed. Electron microscopic analysis of these needle crystals revealed that they are composed of stacks of triple-stranded helices with each strand of the helix made up of subunits of hemagg...

In this study we describe a beads-based assay for rapid, sensitive and specific isolation and detection of influenza vaccine hemagglutinin (HA). Amplification of the hemagglutinin signal resulted from binding of an electrochemical label as quantum dots (QDs). For detection of the metal and protein part of the resulting HA-CdTe complex, two differential pulse voltammetric methods were used. The ...

background and aims: influenza (flu) is a respiratory infection in mammals and birds. it is caused by an rna virus in the family orthomyxoviridae. the virus is divided into three main types. influenza virus type a is found in a wide variety of bird and mammal species and can undergo major shifts in immunological properties. hemagglutinin (ha) is an important influenza virus surface antigen that...

1. A procedure is given for the preparation of purified soybean hemagglutinin from untoasted soybean flour. The final purification step involves column chromatography on calcium phosphate. The homogeneity of the purified protein was ascertained chromatographically and electrophoretically. 2. The purified soybean hemagglutinin was found to contain mannose (4.5 %) and glucosamine (1%). 3. The car...

Newcastle disease (ND), caused by the virus (NDV), is transmitted poultry with severe infectivity and a high fatality rate. The fusion (F) protein on NDV envelope facilitates merger of viral host cell membranes help homologous hemagglutinin-neuraminidase (HN). transmembrane (TM) domains proteins are typically required for fusion, but key amino acids in F TM have not been identified. Site-direct...

Influenza poses a significant threat to public health, particularly among the elderly, young children, and people with underlying dis-eases. The manifestation of severe conditions, such as pneumonia, highlights importance preventing spread influenza. An accurate cost-effective prediction host antigenic sub-types influenza A viruses is essential addressing this issue, in resource-constrained reg...
