Background: Bangladesh is identified as one of the countries with severe health worker shortages. However, thereis a lack of comprehensive data on human resources for health (HRH) in the formal and informal sectors inBangladesh. This data is essential for developing an HRH policy and plan to meet the changing health needs ofthe population. This paper attempts to fill in this knowled...

PrfA is the major transcriptional activator of most virulence genes of Listeria monocytogenes. Its activity is modulated by a variety of culture conditions. Here, we studied the PrfA activity in the L. monocytogenes wild-type strain EGD and an isogenic prfA deletion mutant (EGDDeltaprfA) carrying multiple copies of the wild-type prfA or the mutant prfA* gene (strains EGDDeltaprfApPrfA and EGDDe...

An intravenous injection of a lymphocyte pro-inflammatory factor (LpIF), obtained from rat spleen, restored diminished fluid and cellular responses in carrageenan pleurisy in leucopenic animals. A similar filtrate of bone marrow cells had no restorative properties. Previous results from elsewhere indicated a single pro-inflammatory activity on the fluid component of inflammation. We propose tha...

The Internet provides a best-effort transfer service with no service guarantees. Inthe last few years, however, there has been growing interest in providingQuality of Service(QoS) guarantees in the Internet. It has been mainly driven by multimedia and real-timeapplications, which require a certain level of service. Thus, the IETF is working on thedevelopment of new proposals...

Environmental factors such as diet, intake of vitamin D supplements and exposure to sunlight are known to influence serumvitamin D concentrations. Genetic epidemiology of vitamin D is in its infancy and a better understanding on how geneticvariation influences vitamin D concentration is needed. We aimed to analyse previously reported vitamin D-relatedpolymorphisms in relation to ser...

Graphene has attracted great attention due to its extraordinary electronic, thermal, mechanical, and optical properties [1]. In photonics, graphene have been exhibited outstanding properties such as transparency, wavelength-independent optical absorption, satuable absorption, electron-hole pair generation, third-order nonlinearity, and electro-absorption. Graphene has been used as a transparent...

Although blue-white screening based on α-complementation has been widely used in the screening of genetically modified bacteria, only a single blue-white screening is typically not enough to eliminate false positives. Sometimes, a secondary blue-white screening for the target colonies is required. In this study, two methods were used to investigate the feasibility of secondary blue-white screen...

We present the results of the analysis of the BeppoSAX LECS and MECS pointed observation of the E4 galaxy NGC 3923, for which previous X-ray measurements had given a medium X-ray to optical ratio LX/LB. The spectral analysis over (0.5–10) keV reveals that the best representation of the data is the superposition of two thermal components at temperatures of 0.4 keV and 6–8 keV. The total emission...

ABSTRACT: Nowadays, consumption of whole flours and flours with high extraction rate is recommended, because of their large amount of fiber, vitamins and minerals. Despite nutritional benefits of whole flours, concentration of some undesirable components such as phytic acid is higher than white flour. In this study, the effect of several sourdough lactic acid bacteria on toast bread was investi...
