The anti-feedant and growth inhibitory effects of seed extracts of custard apple in hexane, ethyl acetate and methanol were tested against neonate and 7 days old larvae of the Khapra beetle, Trogoderma granarium, using a feeding bioassay. The LC50 values for hexane, ethyl acetate and methanol extracts were 1195.41, 305.36 and 1446.32 ppm for neonate larvae; 5805, 1300 and 5815 ppm for 7 days ol...

Eight different types of nanostructured perovskites based on YCoO 3 with different chemical compositions are prepared as gas sensor materials, and they are studied with two target gases NO 2 and CO. Moreover, a statistical approach is adopted to optimize their performance. The innovative contribution is carried out through a split-plot design planning and modeling, also involving random effects...

Abstract The influence of pharmaceutical residues and heavy metals on living organisms has received global attention. present study assessed the interactive effect antibiotic in soil, as contaminated food with cadmium (Cd) oxytetracycline (OTC) isopod Porcellio leavis. It was fed fresh plant leaves different concentrations cadmium, Cd+OTC1000 ppm, Cd+OTC2000 ppm Cd+OTC3000 for 4 weeks. changes ...

BACKGROUND Arsenic is a ubiquitous environmental toxicant, and abnormalities of the skin are the most common outcomes of long-term, low-dose, chronic arsenic exposure. If the balance between keratinocyte proliferation, differentiation, and death is perturbed, pathologic changes of the epidermis may result, including psoriasis, atopic dermatitis, and certain forms of ichthyosis. Therefore, resea...

conclusions results of this study suggest that the extract alone of peganum harmala and heracleum persicum may be useful to treat bacterial infections. objectives the major aim of the current study was to investigate the antimicrobial activity of an extract of the peganum harmala flower and heracleum persicum against acinetobacter baumannii. materials and methods the minimum inhibitory (mic) co...

Epidemiological and laboratory studies indicate an inverse relationship between the risk of colon cancer development and intake of nonsteroidal antiinflammatory agents, including aspirin. One of the mechanisms by which nonsteroidal antiinflammatory agents inhibit colon carcinogenesis is through the inhibition of prostaglandin production by cyclooxygenase isozymes (COX-1 and COX-2). Overexpressi...

High mass measurement accuracy of peptides in enzymatic digests is critical for confident protein identification and characterization in proteomics research. Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) can provide low or sub-ppm mass accuracy and ultrahigh resolving power. While for ESI-FT-ICR-MS, the mass accuracy is generally 1 ppm or better, with matrix-assisted l...

Background: Bacterial blight pathogen (Xanthomonas axonopodis pv. cyamopsidis) of clusterbean causes considerable damage every year during Kharif season and sometimes become very severe, which results in heavy loss grain yield. Methods: On the basis vitro studies, most effective botanical, antibiotic fungicide at highest concentration were used as individual its combinations field experiment tw...

STUDY DESIGN Research OBJECTIVE.: The goal of this study was to investigate whether P. acnes infection of the intervertebral disc can be detected noninvasively by NMR spectroscopy. SUMMARY OF BACKGROUND DATA Microbiological studies of surgical samples suggest that a significant subpopulation of back pain patients may have occult disc infection with P. acnes bacteria. This hypothesis is furthe...
