No full textSynthesis of Silver Nanoparticles from Sargassum Tenerrimum and Screening Phytochemicals for Its Antibacterial Activity
No full textSynthesis of nanomaterials by biological approach is innovative, cheaper and environmental friendly and requires less-labor. In this regard, the present study focused on the synthesis of silver nanoparticles from the extract of Sargassum tenerrimum. Synthesized silver nanoparticles were well-characterized by UV-Visible Spectroscopy (UV-Vis), Fourier-Transform Infra-red Spectroscopy (FT-IR), Transmission Electron Microscopy analysis (TEM) and Dynamic Light Scattering (DLS). It was found that spherical shaped nanoparticles of size 20 nm were found in TEM analysis and showed effective anti-bacterial activity against standard reference strains. Altogether, extracts from seaweed were screened for phytochemicals followed by FT-IR prediction to reveal chemical functional groups present. The results showed that the anti-bacterial activity of silver nanoparticles was comparably higher than the phytochemicals present. Therefore, the present study elucidates silver nanoparticles can play a vital role in nano-based therapy in future
Mental health and sleep quality among health-care students during the second wave of COVID-19 pandemics in Erode District: A cross-sectional study
No full textBackground: The mental health of medical and paramedical college students is likely to be severely affected by the second wave of COVID-19 pandemics, affecting their learning process. Aim and Objectives: The aim of the study was to assess the prevalence and level of stress, anxiety, and depression of health-care students living in Erode district, and their sleep quality during the second wave of COVID-19 pandemic. Methodology: This is a cross-sectional study and it was conducted via Google Form survey completed by students studying health-care-oriented courses such as MBBS and nursing students in Erode district. Results: A total of 318 students had completed data on demography details, sleep quality by Pittsburgh Sleep Quality Index, and mental health by Depression Anxiety Stress Scales questionnaires. The prevalence of borderline abnormal depression, anxiety, and stress was 25.5%, 25.2%, and 16%, respectively. The prevalence of poor sleep was 45% and overweight and obese students (P = 0.03) had more poor sleep scores than others. Nursing students had significant depression (P = 0. 03), anxiety (P = 0.04), and stress (P = 0.03) score than others. Conclusion: During the second wave of the COVID-19 epidemic, there was a significant rise in the incidence of unpleasant feelings and attitudes among health-care students stationed in COVID treatment hospitals, as well as poor overall sleep quality. We hope that this research will lead to an additional investigation into the mental condition of health-care students during public health emergencies. Furthermore, special emphasis must be devoted to improving the sleep quality of health-care students who are constantly exposed to the current viral pandemic due to their profession
