We deyeloped a simple screening method for antioxidant-producing strains using 1,1-diphenyl-2picrylhydrazyl (DPPH) and screened bacteria from 16 kinds of marine animals that lived in different enyironments in the sea to find 112 bacterial iso]ates producing antioxidants. Guided by decoloration of DPPH sprayed on silica gel TLC, uric acid, indole, 3,4-dimethoxyphenol, and 3-hydroxyindolin-2-one ...

Drought stress is a serious adverse factor limiting growth and productivity of sunflower. Evaluation of defense systems is important for producing resistant cultivars. In this study, some agro-morphological and molecular characteristics of six sunflower lines were evaluated under normal and irrigation at 40 and 60% of field capacity in randomized complete block design (RCBD). The results showed...

Antisera raised against purified cytidylyltransferase (CT) immunoprecipitated CT activity from liver cytosol and detected the M(r) 45,000 subunit of CT on Western blots. Antisera detected a M(r) 112,000 protein on Western blots of liver cytosol. This protein was not detected in purified CT and was not detected by preimmune serum. The 112-kDa antibodies, isolated by affinity chromatography, did ...

  Random amplified polymorphic DNA (RAPD) markers were used to estimate genetic relationships between two seasonal immigrant forms (namely fall-run and spring-run) of Caspian trout Salmo trutta caspius. In this regard, 62 fin tissue samples were collected from southern parts of the Caspian Sea basin and examined with 16 oligodecamer primers to asses their genetic diversity as well as probable s...

Review of the medical and audiologic literature indicates that MIHL occurs among musicians, with varying incidences ranging up to 58% in classical musicians and up to 30% in rock/pop musicians. In addition, studies show that musicians routinely face sound pressure levels (SPLs) in potentially hazardous ranges, extending up to 120-130 dBA only 3 feet from the speaker in amplified rock/pop bands,...

H. parasuis isolates (n=112) from pigs were tested for antimicrobial susceptibility against 23 antimicrobial agents by the disk diffusion method. All isolates were sensitive to Florfenico and most strains were sensitive to Cefotaxime (103/112; 92%), Ceftazidime (99/112; 88.4%), Chloramphenicol (90/112; 80.4%) and Gentamicin (85/112; 75.9%). High resistance levels to Nalidixic acid (84.8%), TMP ...

Microsatellites or simple sequence repeats (SSRs) are very effective molecular markers in population genetics, genome mapping, taxonomic study and other large-scale studies. Variation in number of tandem repeats within microsatellite refers to simple sequence length polymorphism (SSLP); but there are a few studies that are showed SSRs replication slippage may be occurred during in vitro amplifi...

Assessment of genotoxins-induced DNA damage and mutations at molecular level is important in ecogenotoxicology. Treatment with Peganum harmala crude extract can result in cytotoxic, carcinogenic and mutagenic effects. Mutagenesis is indicative of genetic instability and can be assayed using microsatellites or simple sequence repeats (SSRs). The application of SSR marker analysis using capillary...

Serum protein electrophoresis (SPE) is the hub of laboratory testing for monoclonal gammopathies and is a component of almost all diagnostic panels (1–3 ). The sensitivity of SPE as a screening test, however, is dependent on how SPE abnormalities are defined (4 ). Discrete, quantifiable electrophoretic bands (M-spikes) are almost always monoclonal proteins. Subtle abnormalities such as fuzzy ba...
