Implementation of triticale in nutrition of non-ruminant animals
Cognition of chemical composition and nutritive values of triticale grain as well as the effect of its application in non-ruminant animal nutrition were pointed out in this paper. There is a high level of proteins in the grain of triticale (2 to 3% more than wheat and 4% more than rye), with very beneficial amino acid composition, and is the reason for its usage in domestic animals nutrition....

In vitro mutagenesis in Rosa hybrida using oryzalin as a mutagen and screening of mutants by randomly amplified polymorphic DNA (RAPD) marker
Apical and axillary meristems of Rosa hybrida Cv. First red were pretreated with various concentrations (0, 5.0, 10.0, 15.0, 20.0, 25.0 and 30.0 µM) of oryzalin (C12H18N4O6) to induce variation in vitro. The present results indicate that fifty percent survivability (LD50) was obtained in 20 µm oryzalin. Both the treated and untreated meristems were cultured in Murashige...

Effects of salicylic acid on wheat salt sensitivity
Salicylic acid (SA), a plant phenolic compound, is now considered as a hormone-like endogenous regulator, and there is a great interest to clarify its role in the defence mechanisms against biotic and abiotic stressors. In this study, investigations on the effects of foliar-applied SA on salt sensitivity, hydrogen peroxide (H2O2) generation and activities of antioxidant enzymes like peroxidase (POX) and catalase...

Antifungal activity of root, bark, leaf and soil extracts of Androstachys johnsonii Prain
Extracts of leaf, root, soil and bark of Androstachys johnsonii Prain (commonly called Lembobo ironwood) screened for antifungal activity had a significant inhibitory effect on the most of fungi tested in this investigation. Of the four fungi tested in the present study Fusarium solani was significantly inhibited by all extracts (that is, 0.01% of leaf, root, bark; 0.1% leaf, root, soil and bark; 1%...

Study of Beauveria bassiana growth, blastospore yield, desiccation-tolerance, viability and toxic activity using different liquid media
Beauveria bassiana was grown on three liquid media containing casaminoacids, corn steep liquor or peptone. After incubation, the blastospore counts reached 6.38 × 109 blastospores/ml, in the medium containing sucrose and corn steep liquor, which was significantly higher than the obtained with media containing casaminoacids or peptone. The medium containing corn steep liquor produced predominately...

Carbohydrate metabolism in tomato (Lycopersicon esculentum Mill.) seedlings and yield and fruit quality as affected by low night temperature and subsequent recovery
In order to clarify carbohydrate content and enzymes activities involved in sugar metabolism in tomato seedling leaves and yield and fruit quality under low night temperature and subsequent recovery, tomatoes (Lycopersicon esculentum Mill. cv. Liaoyuanduoli) were grown in different climatic controlled-environment chambers with day/night temperature regimes of 25/15, 25/9 and 25/6°C for 9...

Improvement of nutritional quality and antioxidant activities of yeast fermented soybean curd residue
This study evaluated the potential use and improves the health beneficial properties of the waste of soybean manufacturing products by solid-state fermentation of six GRAS different yeast strains, including extractable antioxidant activities and bioavailable nutritional compositions. In comparison with non-fermented okara (control), some levels of value addition occurred as a result of the fermentation. The protein...

Leukemia: Derived heat shock protein gp96-peptide complex contribution to T cell and dendritic cell activation
The molecular chaperone, heat shock protein gp96 (HSP-gp96), has been shown to have roles in the synthesis, processing and transport of tumor antigens. Therefore, the capacity for HSP-gp96 to induce dendritic cells (DCs), thymus-dependent lymphocytes (T lymphocytes), natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) was investigated. Recombinant adenovirus (AD) containing HSP-gp96 (AD-gp96), as well as...

The role of stethoscopes in the transmission of hospital infections
Stethoscopes are one of the most commonly used medical devices and have been reported to be potential sources of hospital acquired infections. In this study, we aimed to find out the bacterial contamination of stethoscopes used by health-care staff. Swab samples were taken from the surface of the diaphragm of the stethoscopes used by health personnel in four hospitals including three second-line and one third-line...

Genetic analysis of farmed and wild stocks of large yellow croaker Larimichthys crocea by using microsatellite markers
The large yellow croaker (Pseudosciaena crocea) is one of the most economically important mariculture fish species in China. In this study, the genetic diversity and relationship among a wild stock, four farmed stocks and a selectively bred strain of large yellow croaker were assessed by 14 microsatellite markers. A total of 108 different alleles were detected over all loci. The average number of allele per...

Biological control of Sclerotinia sclerotiorum (oilseed rape isolate) by an effective antagonist Streptomyces
Sclerotinia sclerotiorum (Lib) De Bary, the causal agent of stem rot of oilseed rape, is one of the most important phytopathogens. In order to find appropriate biocontrol agents, antagonistic and especially chitinolytical activities of 110 soil actinomycetes were examined. Among assayed isolates, Streptomyces sp. isolate 422 significantly reduced (P ≤ 0.01) the incidence of disease....

Antibiotic resistance of Escherichia coli, Listeria and Salmonella isolates from retail meat tables in Ibadan municipal abattoir, Nigeria
Antibiotics sensitivity test was assayed on thirty (30) isolates (10 each forEscherichia coli, Listeria and Salmonella) from retail meat (beef) tables in Ibadan municipal abattoir, Nigeria. The isolates were tested for sensitivity for eight (Listeria) and ten (Escherichia coli and Salmonella) commonly used antibiotics using Bauer-Kirby disc diffusion assay. Antibiotics sensitivity...
