Abstract:
BACKGROUND Capparis decidua and Selenium have several antibacterial properties along with other highly desirable properties, but for long they have not been explored. Nanoparticles are efficient in transporting drugs as they are easily absorbed by the body due to their small size. We wanted to evaluate the antibacterial activity of Capparis decidua mediated selenium nanoparticles against Streptococcus mutans, Lactobacillus, and Enterococcus faecalis. METHODS 4 wells were dug in three Petri dishes of Agar which were coated with a layer of bacteria, Streptococcus mutans, Lactobacillus and Entero

ABSTRACT Resistance to bile is a prerequisite property of the gastrointestinal bacterial flora. Bile acids are powerful detergents, and resistance to sodium dodecyl sulfate (SDS) has therefore often been considered relevant to studies of bile resistance. We have studied the effects of bovine bile (BB) and SDS on Enterococcus faecalis V583 by traditional growth studies and microarrays. Transcriptional responses were studied by time course experiments. In the presence of BB (V583-BB) or SDS (V583-SDS), 308 and 209 genes were identified as differentially expressed at one or more time points, resp

Antimicrobial peptides (AMPs) are considered as a promising agent to overcome the drug-resistance of bacteria. Large numbers of AMPs have been identified from the skin secretion of Rana pipiens, including brevinins, ranatuerins, temporins and esculentins. In this study, the cDNA precursor of a broad-spectrum antimicrobial peptide, ranatuerin-2Pb, was cloned and identified. Additionally, two truncated analogues, RPa and RPb, were synthesised to investigate the structure-activity relationship of ranatuerin-2Pb.

Abstract:
In this study, β-glucan was orally administered and irradiated with whole body 2 Gy. It was then confirmed that the mortality of mice and tumor growth of mice with tumors were significantly reduced. Since the number of leukocytes and lymphocytes increased with a single dose of β-glucan, the crystal was encountered where the radioprotective effect of β-glucan was probably increased by the hematopoietic action of irradiated mice. In previous studies, β-(1–3)-D-glucan extract has a radioprotective effect and an antitumor effect, and regarding the mechanism of action, the immune activity and antioxidant were elucidated. In this study, we investigated the antitumor effects of β-glucan on radiation, protection of immune disorders, and antioxidant effects. After intraperitoneal inoculation of about 2 x 106 sarcoma 180, ICR mice were administered 200 mg/kg β-glucan every other day every two weeks. We irradiated 2 Gy radiation 3 times and counted the number of white blood cells and lymphocytes. In addition, body weight and tumor size were measured 2 weeks after cancer cells were seeded. Antioxidant activity was measured using the AAPH (2,2-azobis (2-amidinopropane) dihydrochloride) method. There was a clear decrease in tumor size in the radiation and glucan groups compared to the group receiving only cancer cells that increased tumor size over time. Almost all mice inoculated with only cancer cells died two weeks after radiation, but two-thirds of radiation and the glucan group were alive. Regardless of radiation exposure, the number of leukocytes and lymphocytes increased when β-glucan was administered. Antioxidant activity has been demonstrated in both groups of glucans. These results may indicate that administration of β-glucan increases immune activity, prevents side effects during cancer radiotherapy, and provides a supplemental tool for the treatment of cancer.
