The antiprotozoal effect of saponins is transitory, as when saponins are deglycosylated to sapogenins by rumen microorganisms they become inactive. We hypothesised that the combination of saponins with glycosidase-inhibiting iminosugars might potentially increase the effectiveness of saponins over time by preventing their deglycosylation in the rumen. Alternatively, modifying the structure of t...

OBJECTIVE Health behaviors (HBs) are major determinants of health, illness, and mortality. Theoretical efforts aimed at understanding their nature and the processes involved in their initiation and maintenance have largely ignored differences among them. Therefore, the objective of this research was to establish a reliable and valid common-sense taxonomy of HBs. METHODS The first study create...

BACKGROUND Recombinant DNA technologies have played a pivotal role in the elucidation of structure-function relationships in hemoglobin (Hb) and other globin proteins. Here we describe the development of a plasmid expression system to synthesize recombinant Hbs in Escherichia coli, and we describe a protocol for expressing Hbs with low intrinsic solubilities. Since the α- and β-chain Hbs of dif...

The aims of the present study were to determine (i) the long-term immunogenicity and the decay rate of hepatitis B virus (HBV) surface antibody (anti-HBs) from universal hepatitis B vaccination at infancy for a healthy population in an area of hyperendemicity and (ii) whether the anti-HBs levels measured by enzyme immunoassay (EIA) were closely correlated with those assayed by radioimmunoassay ...

BACKGROUND Follow-up studies of recipients of hepatitis B vaccine from endemic areas have reported loss of antibody to hepatitis B surface antigen (anti-HBs) in a high proportion of persons vaccinated at birth. In contrast, the long-term durability of antibody in persons vaccinated as adults in nonendemic areas is not well defined. We aimed to assess the durability of anti-HBs among healthcare ...

The safe and economic operation of nuclear power plants (NPPs) requires that the behaviour and performance of the fuel can be calculated reliably over its expected lifetime. This requires highly developed codes that treat the nuclear fuel in a general manner and which take into account the large number of in uences on fuel behaviour, e.g. thermal, mechanical, chemical, etc. Although many mature...

Nature gas hydrates (NGHs) are regarded as a potential alternative energy source due to their huge reserves and wide distribution. According the geophysical surveys, pore-filling occupy large proportion of global hydrate reserves, especially for marine regions. Therefore, with novel pore-scale 3D morphological modeling algorithm, this study systematically studied effect particle size on physica...

Hepatitis B merupakan penyakit inflamasi dan nekrosis sel hati yang disebabkan oleh infeksi virus hepatitis (VHB). Kehadiran anti-HBs faktor penting dalam diagnosis prognosis VHB. Rapid test adalah salah satu metode pemeriksaan selain ELISA untuk mendeteksi adanya anti-HBs, lebih praktis penggunaan ekonomis. Tujuan penelitian ini mengetahui nilai sensitivitas spesifisitas rapid Intec® terhadap ...

conclusions results demonstrated the relatively high prevalence of hcv infection in the patients. applying sensitive methods to screen blood units is recommended to minimize the risk of transfusion associated hepatitis. objectives the current study aimed to evaluate characteristics of hepatitis in patients with β-tm visiting imam khomeini hospital of zabol, in sistan and baluchistan province of...
