Knowledge, attitude and practices about adverse drug reaction among medical students in a medical college: an observational study

Background: Adverse Drug Reactions (ADRs) are usually associated with drugs which may or may not go unnoticed. ADRs are of great concern for any health care set up as they directly or indirectly add to the cost of treatment, prolongation of treatment, hospital stay or sometimes may even cause death. Spontaneous ADR reporting forms an important part of pharmacovigilance.Methods: An observational study was carried out in a medical college to know the knowledge, attitude and practice being followed by them in a Medical College.Results: In present study all the students had knowledge about ADRs. Only 86.7% of the students knew how and where to report an ADR. 73.3% of the students knew who can report an ADR and they had visited ADRM centre but only 60% of the students knew which ADR is to be reported. 88% of the students had an attitude that it is important to report an ADR and 86.7% told that it is useful to report an ADR. 99.3% of the students had never reported an ADR. Only 1.4% of the students had really visited ADRM centre of their institution but none of the students had ever visited wards or OPDs to look for ADRs. 26.7% of the students said that they will report an ADR if they see it ever.Conclusions: There is good knowledge about ADRs and ADRM centre among students, but it needs to bring ADR reporting into practice by actively doing hands on workshops or by adding this exercise into practical curriculum

Health And Social Status Of Senior Citizens In Rural Areas

Research Problem: What is the quality of life of the elderly people, as also the available support system, in rural areas? Objectives:i) To determine the demographic profile of eld­erly ii) To assess the socio-economic, nutritional, health, morbidity and dependency status, and health care utilization. Study Design: Population based cross sectional study. Setting: Community Development   Block - Lakhanmajra Participants: Persons above the age of 65 years. Sample Size: 809 elderly above the age of 65 years. Study Variables: Demographic profile, Literacy, Oc­cupation, Health, Nutrition, Mobility, Dependency, Substance abuse, Support system. Statistical Analysis: By simple proportions. Result: In this study, majority ofthe elderly were self reliant and mobile, being an asset to the family and led socially useful and productive lives.

Alterations in Antioxidative Potential of Ocimum Cultivars as a Method to Characterize UV-B Tolerance

The comparative alterations of UV-B tolerance and recovery on lipid peroxidation and modulation in the contents of free radicals, enzymatic and non-enzymatic antioxidants in leaves of Ocimum sanctum, Ocimum basilicum and Ocimum gratissimum were studied. Lipid peroxidation measured in terms of MDA level increased with UV-B doses and the ratio was higher in Ocimum basilicum compared to Ocimum gratissimum. Recovered leaves showed lower MDA content and hydroxide radicals. Ascorbate, flavonoid and proline contents increased highly in stressed and recovered leaves of Ocimum gratissimum compared to Ocimum basilicum with an increase in UV-B doses. Higher free radical scavenging capacity and more efficient antioxidant potential of Ocimum gratissimum cultivars were proved in vivo, using the thiobarbituric acid assay in liver and muscle assay systems of ovarian models. The present findings suggested that UV-B doses have modulated the antioxidative machinery of Ocimum cultivars, though the results proved that significant cultivars differ in responses to UV-B. Differences in responses are closely related to differences in the activities of antioxidants and overall growth responses. A significant conclusion can be drawn from the findings that improved tolerance to UV-B stress may be accomplished by increased capacity of antioxidant system of plants

Ecological Studies of the River Krishna near Gadwal, Telangana with Reference to Water Quality

Ecological studies in the river Krishna have been studies for a period of two years (May 2015 to April 2017). Physico-chemical and phycological aspects have been investigated to assess the quality of water. The water was well oxygenated with an alkaline pH, organic matter, chlorides and nutrients were recorded at low concentrations. Diatoms constituted the dominant group of algae. Multiple regression analysis was employed to discover the relative importance of various physico-chemical variables on the abundance and distribution of algae. Mathematical equations were derived involving the physico-chemical variables for better prediction of algal number

Particle Engulfment and Pushing by Solidifying Interfaces

The scientific objectives of the work on Particle Engulfment and Pushing by Solidifying Interfaces (PEP) include: (1) to enhance the fundamental understanding of the physics of interaction between inert particles and the solidification interface, and (2) to investigate aspects of melt processing of particulate metal matrix composites in the unique microgravity environment that will yield some vital information for terrestrial applications. The proposal itself calls for a long-term effort on the Space Station. This paper reports on ground experiments performed to date, as well as on the results obtained from two flight opportunities, the LMS mission (1996) and the USMP-4 mission (1997)

Phytotoxic effect of the extracts of Parthenium hysterophorus L. on the germination, seedling growth and biomass of some agricultural crops

This study was conducted to assess the phytotoxic effect of invasive species: Parthenium hysterophorus L. on the germination, seedling length and biomass of Zea mays, Macrotyloma uniflorum and Triticum aestivum, in order to explore its potential as noxious species. In this study, the allelopathic substances were extracted with distilled water and methanol from the aerial and underground part of P. hysterophorus L. in different concentration (1, 100, 150, 400 mg mL–1). The results of the study revealed that the methanol fraction of roots at 400 mg mL-1 concentration had the highest phytotoxic activity as compared to the double distilled water extract. Germination (%) was observed to be maximum (90%) for Z. mays with double distilled water above ground part extract at 1 mg mL-1 and lowest (10%) for M. uniflorum L. in 400 mg mL-1 both aerial and underground plant extracts at the last day of measurement. Mean shoot and root length were observed highest (17.6cm and 6.1cm respectively) in Z. mays with aerial double distilled water extract at 1 mg mL-1 concentration and it was found lowest (3.2cm and 2.8cm) in M. uniflorum with underground part double distilled water extract at 400 mg mL-1. Biomass was recorded highest (1.97 g/100cm2) in Z. mays in aerial part extract and lowest (0.83 g/100 cm2) in horse gram in underground part extract at concentration of 400mg mL–1 with double distilled water extract. In methanol, both aerial and underground part extracts, the germination observed only at 1mg mL-1 concentration

Microstructural evolution under low shear rates during Rheo processing of LM25 alloy

© ASM InternationalMicrostructural features of LM25 alloy processed by two different routes: (1) conventional casting, and(2)shear casting based on inclined heated surface are studied. The microstructures of the primary phase for the shear-cast samples show rosette or ellipsoidal morphologies. Heat transfer of contacting melt with the inclined tube surface and shear stress exerted on the layers of the melt as result of gravitational force are crucial parameters for the microstructural evolution. Compared to those produced by conventional casting, shear-cast samples have a much improved tensile strength and ductility due to globular microstructure

Decrease in alpha-1 antiproteinase antitrypsin is observed in primary Sjogren's syndrome condition

Primary Sjogren’s syndrome (pSS) is a systemic autoimmune disease that is characterized by the infiltration of immune cells. Although the loss of salivary gland function is a major manifestation observed in pSS, the factors that could promote these changes in salivary gland tissue in pSS is not yet determined. Herein, we provide evidence that loss of alpha-1 antiproteinase antitrypsin could contribute to the induction of pSS. Alpha-1 antiproteinase antitrypsin belongs to the family of serpin proteins that function as protease inhibitors and protect secretory cells against proteases, especially to elastases that is secreted from lymphocytes. Importantly, expression of alpha-1 antiproteinase antitrypsin was decreased (more than 3-fold), along with an increase in elastase expression, in pSS samples when compared with age-matched non-SS-SICCA patients. Consistent with the human data, loss of alpha-1 antiproteinase antitrypsin, as well as an increase in immune infiltration, was observed in IL14α transgenic mice that exhibit SS like symptoms. Moreover, an age-dependent increase in elastase expression was observed in IL14α transgenic mice along with a decrease in total saliva secretion. Importantly, a 4-fold increase in microRNA132 expression, but not in other microRNAs, and increased DNA methylation in the promoter/noncoding region of serpina gene was observed in pSS, which could be responsible for the inhibition of alpha-1 antiproteinase antitrypsin expression in salivary gland cells of pSS patients. Together, these findings demonstrate that epigenetic regulations that include DNA methylation and microRNAs that could modulate the expression of alpha-1 antiproteinase antitrypsin in salivary glands and could be involved in the onset of pSS

Operando visualisation of battery chemistry in a sodium-ion battery by 23Na magnetic resonance imaging

© 2020, The Author(s). Sodium-ion batteries are a promising battery technology for their cost and sustainability. This has led to increasing interest in the development of new sodium-ion batteries and new analytical methods to non-invasively, directly visualise battery chemistry. Here we report operando 1H and 23Na nuclear magnetic resonance spectroscopy and imaging experiments to observe the speciation and distribution of sodium in the electrode and electrolyte during sodiation and desodiation of hard carbon in a sodium metal cell and a sodium-ion full-cell configuration. The evolution of the hard carbon sodiation and subsequent formation and evolution of sodium dendrites, upon over-sodiation of the hard carbon, are observed and mapped by 23Na nuclear magnetic resonance spectroscopy and imaging, and their three-dimensional microstructure visualised by 1H magnetic resonance imaging. We also observe, for the first time, the formation of metallic sodium species on hard carbon upon first charge (formation) in a full-cell configuration

For in vivo use, the near-infrared (NIR) window has been the focus of the majority of studies, because of greater light penetration due to lower absorption and scatter of biological components. Therefore, having both fluorescent and photothermal agents with optical properties in the NIR provides the best chance of improved theranostic capabilities utilizing nanotechnology.Methods: We developed nonplasmonic multi-dye theranostic silica nanoparticles (MDT-NPs), combining NIR fluorescence visualization and photothermal therapy within a single nanoconstruct comprised of molecular components. A modified NIR fluorescent heptamethine cyanine dye was covalently incorporated into a mesoporous silica matrix and a hydrophobic metallo-naphthalocyanine dye with large molar absorptivity was loaded into the pores of these fluorescent particles. The imaging and therapeutic capabilities of these nanoparticles were demonstrated in vivo using a direct tumor injection model.Results: The fluorescent nanoparticles are bright probes (300-fold enhancement in quantum yield versus free dye) that have a large Stokes shift (>110 nm). Incorporation of the naphthalocyanine dye and exposure to NIR laser excitation results in a temperature increase of the surrounding environment of the MDT-NPs. Tumors injected with these NPs are easily visible with NIR imaging and produce significantly elevated levels of tumor necrosis (95%) upon photothermal ablation compared with controls, as evaluated by bioluminescence and histological analysis.Conclusion: MDT-NPs are novel, multifunctional nanomaterials that have optical properties dependent upon the unique incorporation of NIR fluorescent and NIR photothermal dyes within a mesoporous silica platform.Keywords: bioluminescence, in vivo imaging, mesoporous silica nanoparticles, NIR fluorescence, photothermal ablation, theranosti
