objective(s): th2 response is related to the aetiology of asthma, but the underlying mechanism is unclear. to address this point, the effect of nebulized inhalation of inactivated mycobacterium phlei on modulation of asthmatic  airway  inflammation was investigated. materials and methods: 24 male balb/c mice were randomly divided into three groups: control group (group a), asthma model group (g...

this experiment was conducted for evaluating the humoral immune responses induced by poly lactide-co-glycolide acid (plga) microspheres coupled inactivated newcastle disease virus (ndv) vaccine in comparison to an ‘in-house’ prepared inactivated and a live commercial vaccine. plg microparticles containing inactivated ndv were prepared by a double emulsion technique based on solvent evaporation ...

It is demonstrated that crotonyl-CoA reductase (CCR) plays a significant role in providing methylmalonyl-CoA for monensin biosynthesis in oil-based 10-day fermentations of Streptomyces cinnamonensis. Under these conditions S. cinnamonensis L1, a derivative of a high-titre producing industrial strain C730.1 in which ccr has been insertionally inactivated, produces only 15 % of the monensin yield...

Studying inactivated blood plasma of pregnant women and newborns, the authors note a number phenomena proceeding differently in one or another origin.

BACKGROUND Although the 2009 (H1N1) influenza pandemic officially ended in August 2010, the virus will probably circulate in future years. Several types of H1N1 vaccines have been tested including various dosages and adjuvants, and meta-analysis is needed to identify the best formulation. METHODS We searched MEDLINE, EMBASE, and nine clinical trial registries to April 2011, in any language fo...

Porcine reproductive and respiratory syndrome (PRRS) causes significant economic losses to the swine industry worldwide. Although inactivated and live vaccines are commercially available for the control of PRRS, both types of vaccine have not always proven successful in terms of generating a protective immune response, particularly in the case of inactivated vaccines. In this study, we tested w...

conclusions in this study, we isolated b. licheniformis producing an organic solvent-stable protease from oil-contaminated soil. the protease was stable and active in various organic solvents. by purification, the protease could be used as a biocatalyst for organic solvent-based enzymatic synthesis. results according to 16srdna sequencing, strain isa9 was identified as a new strain of bacillus ...

The present study aimed to evaluate the effects of Enterococcus faecalis, inactivated by the common intracanal irrigants sodium hypochlorite (NaOCl) and chlorhexidine (CHX), on osteoblasts. E. faecalis was inactivated with 2% CHX or 5.25% NaOCl. Subsequently, the Cell Counting kit‑8 assay was used to examine the effects of CHX‑ and NaOCl-inactivated E. faecalis on MC3T3‑E1 osteoblast cell proli...

Sodium 7beta-[(R)-2-(N(b)()-o-nitrobenzyloxycarbonyl)hydrazino-3-pheny lpropa namido]cephalosporanate (1) is described as a new type of beta-lactam antibiotic, which undergoes light-induced destruction of its beta-lactam moiety and hence becomes biologically inactive. This type of antibiotic holds the promise of self-destruction over a number of hours of exposure to light, so that it would not ...
