Peroxidase from Coleus Forskohlii: Purification and Biochemical Characterization
Abstract:
In this study, a peroxidase from new source was purified using ion exchange and gel filtration techniques. The recovery for peroxidase activity was 19% with 11-fold purification and specific activity of 749 unit/mg protein. Purified peroxidase demonstrated a molecular mass of 39 kDa using gel filtration and was confirmed as a single band on SDS-PAGE. The purified peroxidase revealed a broad optimum pH activity at 6.0-6.5 and 50°C temperature. The kinetic parameters for purified peroxidase toward H2O2 and guaiacol as substrates were found to be Km = 3.355, 5.395 mM, Kcat = 99.52, 79.56 s-1 and Vmax =1.531, 1.242 µmole ml-1 min-1, respectively. The catalytic efficiency (kcat/Km) of the purified peroxidase was 14.75 and 29.66 s−1 mM−1 for guaiacol and H2O2, respectively. Peroxidase activity was observed to be enhanced by Cu2+, Co2+, Ni2+ and inhibited in the presence of Sn2+, Al3+, Hg2+, NaN3, EDTA and urea. Characterization showed ...

Migration of a Population
Abstract:
On the basis of Hardy – Weinberg law the problem of migration from the genetic point of view is considered. It is proved the linear differential equation of migratory process of a panmictic population. The phase of the solution of this equation is investigated. On the basis of the carried out analysis the dependence of migration velocity of a population on average time of alternation of generations is found. It is shown that migration of primitive people from Africa to Europe needed alternation the several hundred generations. The dependence of migration velocity of a population on the average area developed by a population for year is investigated. Lacks of the carried out analysis owing to absence of the account of natural selection and inbreeding are marked.
Investigation of Edge-Selectively Nitrogen-Doped Metal Free Graphene for Oxygen Reduction Reaction
Abstract:
In order to distinguish the roles of four types of nitrogen species in oxygen reduction reaction, the ketoamine condensation reactions between the ketone group of graphene oxide and amidogen of aniline and o-phenylenediamine were employed to generate –C=N- bond at the edge of graphene nanoplatelets, and then nitrogen-doped graphene nanoplatelets with pyrrolic N, pyridinic N and pyridinic N+-O- rather than graphitic nitrogen were obtained by post thermal treatments. The resulting catalysts were characterized by X-ray diffraction analysis, X-ray photoelectron spectroscopy and electrochemical measurements. It is found that edge-selectively nitrogen-doped graphene nanopaltelets with nitrogen content of up to 4.28 atom% have been prepared. Nitrogen doping helps to improve activity of oxygen reduction reaction slightly, suggesting nitrogen doping at the edge of graphene does not contribute a lot to the enhancement of activity.

Measuring Availability and Prices of Locally Produced and Imported Medicines in Sudan
Abstract:
The objective of this study was to compare the availability and prices of locally produced and imported medicines, in particular after one year from medicines importation restriction and to answer the key questions, did local manufacturers able to coverage national needs of medicines and what is the patient prices for locally produced compared to imported medicines in different sectors and regions of Sudan. The WHO/HAI methodology survey tool was adapted to measure the availability and price of locally produced and imported medicines. Patient price and availability were collected from capital cities of 6 states as per WHO/HAI methodology. Data were collected and analyzed for 50 medicines from the 104 medicines restricted to local manufacturer. Availability was based on whether the medicine w...
A New Dietary Therapy for Chronic Renal Failure: Intestinal Dialysis Technology
Abstract:
A new dietary approach used to lower urea levels in chronic renal failure, and thus simulating dialysis has been recently described. This approach has been increasingly called intestinal or dietary dialysis. The aim of this paper is to describe the emerging evidence, principles, and concepts related to intestinal dialysis.
The Elliptical Aggregates – Idiopathic Granulomatous Mastitis
Abstract:
Idiopathic granulomatous mastitis was initially scripted in 1972 by Kessler and Wolloch and is cogitated as an infrequent, benign, chronic inflammatory disorder. It commonly implicates females of reproductive age group, especially women who have breast fed in the preceding five to six years. Idiopathic granulomatous mastitis is commonly discerned in Asia and Mediterranean region although true incidence is undetermined. Diverse ethnicities delineate a diverse disease prevalence. Elimination of adjunctive causes of granulomatous inflammation makes idiopathic granulomatous mastitis a diagnosis of exclusion. As per the natural history, idiopathic granulomatous mastitis is designated as a self limiting disorder
Emotional Intelligence of Medical Post Graduate Students from Central India: A Cross Sectional Study
Abstract:
Emotionally intelligent doctors are better able to perceive the need of the patient. In today’s world, where patient satisfaction is one of the most important criteria for a successful medical practice, emotional intelligence of doctors plays a vital role. To study emotional intelligence of post graduate medical students. It is a cross-sectional study conducted in Government Medical College and Hospital, Nagpur during January- February 2019. The study participants were one hundred first - year post graduate students. Data collection was done using quick emotional intelligence self administered questionnaire. Data was entered in Microsoft office excels and analyzed with the help of epi info.
Evolution of Anthropometry in Malnutrition
Abstract:
The present paper describes the significance of anthropometric measurements in detecting nutritional status of individuals, specially children. It highlights evolution of anthropometry, discusses importance of various measurements & their role in determining undernutrition & obesity. There is a need to have one measurement to detect obesity & undernutrition both. An ideal such measure is yet to be established.
