Scientometric methods for the evaluation of hemophilia research

This article attempts to highlight quantitatively the growth and development of world literature on hemophilia in terms of publications output as per SCOPUS database (2003-2017). During 2003-2017 a total of 13503 papers were published by the scientists in the field of hemophilia. The average number of publications published per year was 900. The highest number of publications 1095 was published in 2012. Out of 13503 contributions, only 18.48% (2495 papers) of single authored and rest of 11008 papers (81.52%) were multi authored. The study identifies active institutions and country-wise distributions of hemophilia research output. The yearly analysis of data shows that there is a rapid growth of literature from 2011 onwards. There were 126 countries involved in the research in this field. USA is the top producing country with 3986 authorships (29.52%) followed by United Kingdom with 1438 authorships (10.65%). Still, in an international sense, relative productivity of India is low and requires more focused research and development

INTERACTION OF COPPER OXIDE NANOPARTICLES WITH BOVINE SERUM ALBUMIN BY SPECTROSCOPIC STUDIES

Objective: Since structural changes of adsorbed protein are necessary for cellular uptake of nanoparticles (NPs) it is of prime importance to know about structural changes of bovine serum albumin (BSA) when it interacts with CuO NPs–a potential new antitumor drug.Methods: CuO NPs prepared by sol-gel technique were characterized by x-ray diffraction (XRD) and tunneling electron microscope (TEM) techniques. The conformational changes induced by CuO NPs on BSA were studied by various spectroscopic techniques such as steady state and time-resolved fluorescence measurements. The changes in fluorescence emission parameters such as fluorescence intensity, fluorescence emission maximum and lifetimes of fluorescent residues in BSA were studied.Results: XRD analysis showed the average particle size as 32 nm. The TEM micrograph showed particles of different size varying from 10 to 45 nm. Fluorescence quenching was confirmed due to a decrease in fluorescence intensity of CuO NPs–BSA complex. The analysis of lifetime measurements indicated BSA contained two tryptophan (trp) residues that fluoresced in different environments. Static quenching mechanism was confirmed by time-resolved measurements when BSA interacted with CuO NPs.Conclusion: Minor structural changes of BSA protein were observed during the interaction studies

Academic performances by the faculty members of Mother Teresa Women’s University and its affiliated colleges: an evaluative study

An overview of gossypol and methods of its detoxification in cottonseed meal for non-ruminant feed applications

348-358Cottonseed is a by-product of the cotton crop rich in protein and oil. The products obtained from cottonseed are meal, oil, linters and hulls. The defatted cottonseed meal (CSM) is an important ruminant feed. However, its use in small animals is limited due to the presence of gossypol. Gosssypol is a toxic polyphenolic compound present in the entire cotton plant including its seed. The amount of total gossypol in CSM varies with the species and it ranges between 1.0 to 1.5%. Gossypol causes reproductive diseases and its toxicity level varies with the animals. Also, this substance is a compound of interest for pharmaceutical and medical applications. According to US-Food and Drug Administration, the food and feed products should contain less than 0.045% of free gossypol (FG). Researchers developed various methods, pre-processing (glandless cotton) and post-processing (physical, chemical and biological) for detoxification of gossypol in CSM to obtain FG level within this limit. The detoxified CSM finds application in the feed of dairy, poultry, piggery, aquaculture etc. In this review; chemistry, toxicity, bioactivity, and methods of estimation of gossypol and various strategies undertaken so far to detoxify gossypol in CSM for non-ruminant feed applications have been discussed

Rapid synthesis of biocompatible silver nanoparticles using aqueous extract of Rosa damascena petals and evaluation of their anticancer activity

AbstractObjectiveTo optimize the process parameters involved in the green synthesis of silver nanoparticles (G-SNPs) by aqueous extract of Rosa damascena petals and to evaluate the biocompatibility and anti cancer activity of the synthesized silver nanoparticles against human lung adenocarcinoma (A549).MethodsThe process variables that include concentration of extract, mixing ratio of reactants, silver salt concentration and interaction time were analyzed. The compatibility of the G-SNPs was verified by incubating with erythrocytes and the anticancer property of the G-SNPs against A549 cells was performed by MTT assay.ResultsFormation of G-SNPs was confirmed by the visual change in the colour of the reaction mixture from pale yellow to brown yellow. Surface plasmon resonance of synthesized G-SNPs was observed at 420 nm; the size of G-SNPs were analyzed by DLS and found to be in the range of (84.00±10.08) nm. Field emission scanning electron microscope and high resolution transmission electron microscopy analysis confirmed that the G-SNPs were fairly spherical. Fourier transform infrared spectroscopy spectroscopy and X-ray diffraction revealed the characteristic peaks of G-SNPs. Energy dispersive X-ray analysis showed a signal of silver around 3 keV. The synthesized G-SNPs exhibited anticancer activity as evidenced by the MTT assay. IC50 value of G-SNPs was found to be 80 μg/mL.ConclusionThe results of the present study suggest that G-SNPs can be synthesized rapidly within first minute of the reaction; they are biocompatible and possess anticancer activity against human lung adenocarcinoma
