optimization of the fermentation medium for maximum alkaline protease production was carried out. fifteen positive isolates were examined for their extent of alkaline protease production. the most potent producer was identified as bacillus sp. the solid substrate screening showed that the combination of wheat straw and bean husk was the best one. the initial screening by using plackett–burman’s...

Undoubtedly, no specific method exists to measure the cost of displeasure among employees due to unpleasant or non-ergonomic work conditions. Despite the financial impact of these hidden costs on organizations’ performance, these types of expenses are usually ignored. The intangible costs are insubstantial and represent expenses that have no common quantity or labeled value attached to them. Es...

Allergic and other immune-mediated diseases are complex disease states determined by interplay between host genetics and environmental factors. Environmental changes such as fewer infections and reduced exposure to microbial products have been suggested to have led to insufficient regulation of Th1 and Th2 immune responses, causing an increased incidence of inflammatory diseases. The objective ...

Little is known about the pathogenic mechanisms or potential virulence factors of Arcobacter spp. The aim of the study described here was to obtain more insights in the pathogenicity mechanisms of Arcobacter spp. by testing their ability to adhere to, invade and induce interleukin-8 expression in human Caco-2 and porcine IPI-2I cell lines. Eight Arcobacter strains were tested. Four strains were...

Since the 1970s, the establishment and development of the biotech industry has improved exponentially, allowing the commercial production of biopharmaceutical proteins. Nowadays, new recombinant protein production is considered a multibillion-dollar market, in which about 25% of commercial pharmaceuticals are biopharmaceuticals. But to achieve a competitive production process is not an easy tas...

UV irradiation interferes with the induction of T cell-mediated immune responses, in part by causing cells in the skin to produce immunoregulatory cytokines. Recent evidence implicates UV-induced DNA damage as a trigger for the cascade of events leading to systemic immune suppression in vivo. However, to date, there has been no direct evidence linking DNA damage and cytokine production in UV-ir...

This paper describes and generalises experiences from two cases of production system development in the Swedish context. We have observed the successful application of ergonomics to be related to the lack of coordination of human factors across groups responsible for different stages of the production system design process. This problem is magnified by the tendency for ‘ergonomics’ to be the re...

In previous reports, we showed that tumor-derived TGF-beta induced overproduction of IL-10, and these suppressive cytokines caused macrophage suppression in EL4-bearing mice. Proliferation of T cells from EL-4, but not IL-2, whereas T cells from normal mice were responsive to IL-2. A balance between Th1- and Th2-type cytokine production in EL4-T in response to anti-CD3 Ab or phorbor myristate a...
