Structural and functional characteristics of zooplankton as well as the results of biotesting were researched to indicate the ecological status of Mokraya Sura river sites. Zooplankton sampling was performed at the sites of Mokraya Sura river in autumn 2014 and in spring 2015. Species composition and abundance of zooplankton showed that zooplankton is most depressed at the upper sites of the river...
Maize is an agronomic cereal species that is sensitive to nutrient applications, especially nitrogen. Field experiments were conducted in 2011 and 2012 to evaluate the effect of nitrogen and mulching using dried weeds on maize growth and nutrient accumulation. The study was located in the Research Farm of the Agricultural Science Education Unit of the Delta State University, Abraka, Nigeria ((latitude...
It had been determined the contents of total protein, albumin, glucose, urea and activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST), α-amylase in 4-years old individuals of both sexes of prussian carp (Carassius gibelio Bloch, 1782) and roach (Rutilus rutilus Linnaeus, 1758) in different parts of the Zaporozhian Reservoir (Ukraine). The level of biochemical parameters depended...
B-Raf is a multi- drug target serine/threonine protein kinase, involved in the transduction of mitogenic signals from the cell membrane to the nucleus. Mutated B-Raf causes overactive downstream signaling via MEK and ERK, leading to excessive cell proliferation and survival, independent of growth factors causing cancers such as Pancreatic carcinoma. A novel bi-aryl urea- Sorafenib, is a potent inhibitor...
Pteridophytes and more specifically ferns represent a large but threatened group of plants which often serve as important environmental markers for pollution. Reports regarding stress responses in ferns are rare, apart from a few studies involving the ecological distribution and molecular marker studies. This work isolates a glutathione peroxidase enzyme from an aquatic fern widely distributed in...
For studying water exchange in compartments of tissue water of maize, kinetic curves of dilution of tritium labeled water (3Н) were used, with the incubation of plant tissues in it. By resolving the summary kinetic curves into components, we determined the constants of membranes’ permeability for exchange diffusion flux in two compartments of tissue water – membranerestricted water and water of higher...
Studied the population and nesting records of House Sparrow Passer domesticus during winter in Yellampet village, Telangana. The ecological density of House Sparrow was investigated using fixed width transects. The density of sparrow vary from 15 to 335 per hectare in different transects. Bonferroni confidence interval was used to know the preference of location types i.e., houses, shops and hotels...
The study of biological properties of filmforming Staphylococcus aureus strains, including its sensitivity to bacteriophages, is one of the important tasks of laboratory diagnostic service that allows, if it necessary, choose an alternative treatment strategy and to establish the sources of strains. In the study of material from the nose and throat of 26 persons-volunteers the strains of S. aureus...
The paper examines the influence of industrial emissions SO2 and NO2 on the anatomical structure of the annual shoot stems of Salix alba L. in conditions of steppe zone of Ukraine. It reveals high stability of histological characteristics of the studied type to phytotoxic pollutants, which was proved by thickening of almost all anatomical stem parameters. It was ascertained the toxic gases chronic...
Marine algae Gelidium, Grateloupia elliptica Holmes, and Codium fragile are employed for preparation of PANI/seaweed composites. Infrared absorption (IR), electron spin resonance (ESR) spectroscopy measurements are carried out to confirm the resultant structure. The direct use of natural biological materials for polymerisation reaction allows us to production of polymers with characteristic surface...
