True polycythaemia could be primary or secondary. The secondary causes result in polycythaemia either by causing hypoxia or for this reason stimulation to increase red cell production or by increasing stages of erythropoietin (the hormone stimulating red cell production) - eg: tumors (5). Primary polycythaemia is known as Polycythaemia rubra vera, or simply polycythaemia vera which is a type of abnormal bone marrow growth (1,2,3). Primary polycythaemia (Polycythaemia rubra vera) People who su...
The past few decades have seen a massive growth in biological information gathered by the related scientific communities. A deluge of such information coming in the form of genomes, protein sequences, gene expression data and so on have led to the absolute need for effective and efficient computational tools to store, analyze and interpret the multifaceted data. Bioinformatics and computational biology involve the use of techniques including applied mathematics, informatics, statistics, compu...
The capsid protein of the Flaviviridae family members is involved in nucleocapsid formation and virion assembly. However, the influence of C protein-interacting partners on the outcome of pestivirus infections is poorly defined. In this study, the hemoglobin subunit beta (HB) was identified as a C protein-binding protein using glutathione S-transferase (GST) pulldown and subsequent mass spectrometry analysis of PK-15 cells which are permissive cells of classical swine fever virus (CSFV). Coim...
This experiment was designed to investigate and compare the extent of damage to the hair shaft structure caused by henna as the selected natural hair dye and chemical hair dye. The qualitative analysis of hair using a hair hygrometer shows the variation in hair strand length in a fixed moist condition differ between the naturally and chemically dyed hair. The mean length of extension represents the degree of damage of the hair as the hair dyes interfere with the hair shaft structure, causing ...
Oxidative stress and aging (library project) The general “free radical theory of aging” has been in circulation for over 30 years. The detailed mechanisms in specific diseases are now being identified and understood. The objectives of this project will be to identify named diseases associated with aging and oxidative stress and to critically review the mechanisms proposed. References 1. BL Wilkinson, GE Landreth. The microglial NADPH oxidase complex as a source of oxidative stress in Alzheime...
It is a means of determining properties for a section of well under consideration. The physical property of interest is measured by various means and plotted against the well depth. From physical characteristics of a borehole by caliper log to oil & gas detection by complex analogies, logging applications have a tremendous potential in navigating reservoir evaluations. . The log is based on physical measurements made by instruments lowered into the hole. Well logging is done when drilling bor...
Water vapor is important to the weather and climate because of their role in the global climate system. The clear interaction between water vapor and atmospheric events can explain some physical mechanisms of how small scale of atmospheric environment could influence the climate change pattern. To enhance this interaction, this work is aimed to observe the characteristics of coreless winter event using precipitable water vapor (PWV) derived from GPS technique, surface meteorology and solar ra...
The aqueous extract was prepared according to the method described by Thoo et al., with some modifications. Dried M. citrifolia fruit powder of 100 g were soaked in 1000 mL of distilled water and was shake vigorously using shaker for 15 minutes, at room temperature. The mixture was then sonicated for one hour and left refrigerated for 3 days. The mixture was filtered and kept at -80 °C. Then it was subjected for freeze dry to obtain its powder form of the extract. Saline dilution of the e...
Amylase is an enzyme found in the germinating seeds. Imbibition process causes the release of growth plant (gibberelin) which stimulates the synthesis of amylase. Amylase activity is affected by many factors such as temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators. [1] Amylase enzyme in the green bean seeds works best at specific range of temperature. The cotyledons store food for the use of embryo in the form of starch. Amylase ...
Dyes may be defined as compounds that, when applied to a substrate provide colour by a process that alters, at least temporarily, any crystal structure of the coloured substances. Such substances with considerable colouring capacity are widely employed in the textile, pharmaceutical, food, cosmetics, plastics, photographic and paper industries. The dyes can adhere to compatible surfaces by solution, by forming covalent bond or complexes with salts or metals, by physical adsorption or by mecha...
