| Activity and immunodetection of lysozyme in earthworm Dendrobaena veneta (Annelida). | In the present study, lysozyme-like activity against Micrococcus luteus was detected in the coelomic fluid, the extract from coelomocytes, intestine and in the homogenates from cocoons of Dendrobaena veneta. Four hours after immunization with Escherichia coli, the lysozyme activity in the coelomic fluid increased about three times and in the extract of coelomocytes - four times, in comparison to the control. In three cases: of the coelomic fluid, the homogenates from cocoons and the extract from ... | 2012 | 22019387 |
| Peptidoglycan recognition protein 3 (PglyRP3) has an anti-inflammatory role in intestinal epithelial cells. | Intestinal epithelial cells produce cytokines in response to bacterial peptidoglycan (PGN), which is detected by several classes of pattern-recognition receptors (PRRs) as peptidoglycan recognition proteins (PGlyRPs), Toll-like receptor 2 (TLR2) and NOD receptors. All types of PGlyRPs recognize bacterial peptidoglycan and function in antibacterial innate immunity. In this study, we investigated the role of PGlyRP3 in the response of intestinal epithelial cells (Caco-2) to PGN from pathogenic (St ... | 2011 | 22099350 |
| In-vitro antimicrobial activity and synergistic/antagonistic effect of interactions between antibiotics and some spice essential oils. | Spices and herbs have been used for many years by different cultures. The aim of the present study is (1) to investigate in-vitro antimicrobial effects of different spices and herbs (5 species: Rosmarinus officinalis (Rosemary), Coriandrum sativum (coriander), Micromeria fruticosa (L.) Druce subsp. Brachycalyx P.H. Davis (White micromeria), Cumium cyminum (cumin), Mentha piperita (Peppermint) against different bacteria and fungi species, and (2) to discuss the in-vitro possible effects between t ... | 2011 | 21888227 |
| antagonistic intestinal microflora produces antimicrobial substance inhibitory to pseudomonas species and other spoilage organisms. | chicken intestine harbors a vast number of bacterial strains. in the present study, antimicrobial substance produced by lactic acid bacteria (lab) isolated from the gastrointestinal tract of healthy chicken was detected, characterized, and purified. based on 16s rrna sequencing, the bacteria were identified as lactobacillus plantarum vn. the antimicrobial substance produced by this bacterium was designated vn-1 and exhibited a broad-spectrum of activity against many important pathogenic and spoi ... | 2011 | 21913924 |
| Quantification of polyphenols during retting and characterization of bacteria from the Kadinamkulam Backwaters, Kerala. | The retting environment which provides a competitive niche for specialized microbes is speculated to harbour a variety of microbes with high biodegradation potential. In this context, an effort has been made to isolate and identify bacterial species having high tolerance to phenol In vitro. Maximum polyphenol (1.897 mg l(-1)) as observed during the initial period of retting, which decreased as retting proceeded. Based on biochemical characterization, the isolated bacterial strains were identifie ... | 2011 | 21888245 |
| identification and characterization of a serine protease inhibitor (ptserpin) in the swimming crab portunus trituberculatus. | serine protease inhibitors (serpins) play a key role in diverse immune biological processes. a serine protease inhibitor (serpin), namely ptserpin, was identified from the haemocyte cdna library of swimming crab portunus trituberculatus. the full-length ptserpin cdna was 1593 bp, including an open reading frame (orf) of 1227 bp encoding a polypeptide of 408 amino acids with estimated molecular mass of 45.048 kda and theoretical isoelectric point of 7.23. predicted tertiary structure of ptserpin ... | 2012 | 22245590 |

| jbir-78 and jbir-95: phenylacetylated peptides isolated from kibdelosporangium sp. ak-aa56. | the search for metabolites of kibdelosporangium sp. ak-aa56 resulted in the discovery of novel n-phenylacetylated peptides, jbir-78 (1) and jbir-95 (2). compounds 1 and 2 were established to be n-phenylacetylated heptapeptides by extensive nmr and hresims analyses. the absolute configuration of the standard amino acids including a cysteic acid moiety was determined using marfey's method on the acid hydrolysates of 1 and 2. the relative and absolute configurations of a nonstandard amino acid, β-h ... | 2012 | 22264203 |
| synthesis and anti-microbial screening of novel schiff bases of 3-amino-2-methyl quinazolin 4-(3h)-one. | in the present study, novel schiff bases were synthesized by condensation of 3-amino-2-methyl quinazolin-4-(3h)-ones with different aromatic aldehydes. the 3-amino-2-methyl quinazolin-4-(3h)-one was synthesized from anthranilic acid via the 2-methyl benzoxazin-4-one. the chemical structures of the synthesized compounds were confirmed by means of infrared (ir), (1)h-nmr, (13)c-nmr, mass spectral, and elemental analysis. these compounds were screened for anti-bacterial (staphylococcus aureus atcc ... | 2010 | 22247864 |
