An excessive use of toxic plant protection chemicals has irreversibly damaged the soil biology agroecosystems, resulting in a substantial decline productivity. Biocontrol agents, especially microbial biopesticides, are seen as one key solutions to overcome toxicity and pest resistance issues. Biopesticides defined mass-produced agents manufactured from living microorganisms or natural products ...

Lupus nephritis develops from a combination of genetic and environmental factors such as microbial infection. A role for microbial nucleic acids (e.g., via nucleic acid-specific Toll-like receptors [TLR]) was hypothesized, in this context, because microbial nucleic acids can trigger multiple aspects of autoimmunity in vitro and in vivo. Eight-week-old MRL(lpr/lpr) and MRL wild-type mice receive...

Intestinal microbiota is involved in the maintenance of gut homeostasis as well as the regulation of colitisassociated colorectal tumorigenesis. The aberrant host immune signaling and the presence of opportunistic commensals with potential pathogenic characteristics (pathobionts) have been suggested to be incorporated into the genetic paradigm of colon carcinogenesis. The reciprocal relationshi...

In natural settings, microbes tend to grow in dense populations [1-4] where they need to push against their surroundings to accommodate space for new cells. The associated contact forces play a critical role in a variety of population-level processes, including biofilm formation [5-7], the colonization of porous media [8, 9], and the invasion of biological tissues [10-12]. Although mechanical f...

conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...

in this presentation, we review briefly on biogenesis of peroxisomes with regard to the recent findings on biogenesis. peroxisomes perform a range of various functions as oxidation of very long chain fatty acids, generation and removal of hydrogen peroxide, while peroxisomes have also been implicated in β-oxidation of aromatic and cyclic compounds, synthesis of plasmalogens, isoprenoids, lysine...

conclusions dlec1 suppresses tumor cell growth the presence of ap-2α2 and stimulates cell proliferation in the down-regulation of ap-2α2 in dlec1 over-expression stable clones of htc116. results the dlec1 over-expression was found to reduce the number of colonies in colony formation and to induce g1 arrest in seven clones, and apoptosis in one clone in the cell cycle analysis. furthermore, rega...

objective(s):mir-125b has been identified as a tumor suppressor in many tumors, but its role in giant cell tumor (gct) of bone remains poorly understood. the current study aimed to investigate the potential role and mechanism of mir-125b in gct. materials and methods:expression levels of mir-125b in gct tissues were determined using rt-pcr. the cell proliferation was surveyed by direct cell coun...

background: tuberculosis (tb) remains an important health problem throughout the world. despite its significance in public health, mechanisms of protective immunity against mycobacyerium tuberculosis in humans have not yet been understood. objective: to evaluate cell mediated immune response against purified ag 85, ppd and phytohemagglutinin (pha) in patients with tuberculosis and healthy tuber...
