Abstract: The aim of this study was to the investigate the effect of brucellosis infection on paraoxonase-1 (PON1) activity and oxidative status in patients with brucellosis. Sixty patients with brucellosis (47 acute, 13 subacute) and the 67 healthy controls were used in the study. Serum PON1 and arylesterase activities, total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), total free sulfhydryl (-SH), and lipid hydroperoxide (LOOH) groups were determined. In addition, HDL-cholesterol (H…

Abstract: The use of microbes in pest control is an important aspect of integrated pest management (IPM). A Zimbabwean isolate of the fungal entomopathogen Zoophthora radicans was tested for efficacy in the control of Brassica infesting lepidopteran larvae. Z. radicans caused 98.68% mortality on small (1st - 2nd instar) diamondback moth (Plutella xylostella L.) larvae and 21.34% mortality on large (3rd - 4th instar) diamondback moth (DBM) larvae 6 days after treatment. Z. radicans was not effective against larvae of Helicove…

Abstract: The aim of this study is to investigate the viral agents and the viral profile in children under 5 years of age who are referred to our hospital due to acute wheezing. The nasal smears of 55 children who were referred to Kagithane State Hospital from now on (KSH) with acute wheezing between November 2009 and March 2010 were analyzed with multiplex PCR and the distribution of respiratory virus detected in these smears was evaluated retrospectively. Out of fifty five children whose nasal smear results were evaluated…

Abstract: A study was conducted to isolate lactobacilli from the gastrointestinal (GI) tract of broiler chickens and to evaluate their application as a probiotic supplement. The GI contents of 12 broiler chickens from three different ages were collected and cultured on Man Rogosa and Sharp (MRS) agar. In order to determine bacterial species, different grown colonies were separated and subjected to the sequencing of the 16s ribosomal DNA fragment. An auto-aggregation test was performed for 39 isolated lactobacilli bacteria. E…

Abstract: According to the recommendations for the standardization and interpretation of the electrocardiogram (ECC) of AHA/ACCF/HRS declared in 2009, there are more than 30 criteria for diagnosing left ventricular hypertrophy (LVH). The sensitivity of the various criteria is generally quite low. However, the specificity of ECG in LVH could be 85 to 90%, acting as a strong predictor for cardiovascular events. To investigate the proper criteria in epidemiological screening with different purpose, 5209 qualified ECG out of 683…

Abstract: The primary objective of this study was to make a deep investigation on the concentration of chlorophyll a and ash-free dry mass (AFDM) estimates for algae growing on stones in Urumqi River located in an arid region of northwest China. The study was conducted on three sites. A highly improved method for measuring primary productivity in situ was used to estimate the primary production of algae growing on rocks (or algae epilithic) deposited in surface water. The results showed a low biomass with mean chlorophyll a…

Abstract: We determined the in vitro effect of vancomycin on multidrug resistant Staphylococcus aureus isolates and presumptive roles of plasmid DNA using standard microbiological procedures. A total of 32 paper naira notes from seven different hospital sections (mostly from the patients) were analyzed. Thirteen notes (40.6%) gave isolates of S. aureus and subsequent resistant range of between 62.5 and 100% to frequently prescribed antibiotics. The same set of isolates showed three (23.1%) to be susceptible and ten (76.9%) t…

Abstract: In this study, rock phosphate (RP- compost) enriched composts were prepared by mixing rock phosphate with water lettuce (Pistia stratiotes) with and without effective microbes. The treatment comprised of four types and includes control plant material (water lettuce), water lettuce and rock phosphate (WL+RP), water lettuce, rock phosphate, effective microorganisms (WL+RP+EM) and water lettuce, rock phosphate, effective microorganisms and urea (WL+RP+EM+Urea). The present investigation indicates that the nutrients av…

Abstract: The maedi-visna virus (MVV) classified as a lentivirus of the retroviridae family, causes a very common economically important disease in sheep, in many parts of the worlds. Presences of the infection in Turkey have been shown by researches in previous studies. In this study all blood samples were examined by ELISA and PCR to detect MVV antibody and antigen responses, respectively. Hematological findings were monitored and comparing antibody and antigen positive naturally infected (n= 5), antibody positive and anti…

Abstract: Jujube is an important plant in traditional Chinese medicine and is recommended for the treatment of some diseases such as tumors and cardiovascular disease related to the production of radical species resulting from oxidative stress. The objective of this study was to investigate effect of jujube extract on oxidative injury in heart muscles of exhausted training rats. Four groups of animals were studied: (a) sedentary control (n = 8); (b) vehicle-treated control (n = 8); (c) low dose of jujube extract-treated rats…

Abstract: In this work, sudden wilt syndrome in sesame was investigated during varying irrigation treatments. For the four irrigation intervals numbers of infected plants and infected rows were determined in experiments conducted during growing periods. The resulting data were transformed to percent values and regressed against the irrigation intervals. The correlations between the rates of infected plants and irrigation intervals and between the rates of infected rows and irrigation intervals were assessed separately in rep…

Abstract: Global change will definitely introduce changes in agricultural ecosystems that will affect plant productivity. However, the effects on plants will be different for each region depending on the pre-existing climatic conditions and the adaptation potential of local cultivated species. The solar energy from the sun is essential to support the life on our plant, via the process of photosynthesis. However a small proportion of solar spectrum contains short-wavelength ultraviolet-B light (280 to 320 nm), which is delete…

Abstract: A polyphasic approach was used to discriminate among the significantly hemolytic and closely related Bacillus licheniformis strains, NE-1, NE-2 and NE-3. Utilization of the API 20E kit revealed that B. licheniformis NE-1 is unique in its ability to utilize sorbitol as a sole carbon source, whereas B. licheniformis NE-2 is an exceptional in L-arabinose utilization. The phylogenetic analysis using the 16S rDNA 5´end revealed a strong relatedness to B. licheniformis strains found in the GenBank with a similarity perce…

Abstract: Thermophilic microbial diversity in production water from a high temperature, water-flooded petroleum reservoir of an offshore oilfield in China was characterized by enrichment and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis. Six different function enrichment cultures were cultivated one year, at 75°C DGGE and sequence analyses of 16S rRNA gene fragments were used to assess the thermophilic microbial diversity. A total of 27 bacterial and 9 archaeal DGGE bands were excised…

Abstract: Diesel biodegradation and the effect of application frequency were investigated in artificially contaminated soils (loam soil and sea sand) amended with commercial fertilizers and the effect of application frequency. Two sets of four equal portions (2 kg each) of diesel-contaminated soils were amended with 10% (w/w) of 2 different commercial fertilizers at 4 different but regular intervals for up to four times during a 7- week study period. The microcosms were then incubated at 30°C and sampled weekly. One steriliz…
