This study was aimed to determine the antibacterial activity of root bark, leaves, and pericarp extract of Diploknema butyracea and to evaluate the prospective antioxidant activity, total flavonoid, polyphenol, and carbohydrate content. The plant parts were collected and extracted by cold maceration, using hexane, ethyl acetate, methanol, and distilled water. Phytochemical screening of different samples of D. butyracea in different solvents revealed the presence of varied extent of alkaloid, saponin, terpenoid, anthraquinones, tannin, cardiac glycoside, flavonoid, carbohydrate, polyphenol, protein and amino acid, resin, and phytosterol. Our study showed that methanolic root bark extract exhibited the potent antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, and Klebsiella pneumonia with an average zone of inhibition of 17.33 mm, 14.33 mm, and 13.0 mm, respectively. Surprisingly, all of the extracts were insensitive to Escherichia coli. The lowest minimum bactericidal concentration (MBC), 4.6 mg/ml, was observed with the aqueous pericarp extract against S. epidermidis and the highest was of 50 mg/ml shown by ethyl acetate pericarp against K. pneumonia. Our results showed that both the polar and nonpolar components present in the different parts of D. butyracea exhibit prominent antibacterial activities against different bacterial strains. The in vitro 2,2′-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity showed that the methanol extract of root barks displayed the most potent antioxidant activity (IC50 : 6.1 µg/ml). The total polyphenol content of the plant part extracts was observed between 19.48 ± 0.23 and 123.48 ± 1.84 µg gallic acid equivalent/mg of dry extract weight. Likewise, flavonoid content ranged from 40.63 ± 1.28 µg to 889.72 ± 3.40 μg quercetin equivalent/mg of dry extract weight and total carbohydrate content ranged from 11.92 ± 0.60 µg to 174.72 ± 0.60 µg glucose equivalent per/mg dry extract weight. Overall, our study showed that the root bark, pericarp, and leaves extract of D. butyracea evinced prominent antibacterial properties against various pathogenic bacterial strains.

BACKGROUND: This study was designed to evaluate the impact of the COVID-19 pandemic on the learning status of students from different educational boards and universities of Nepal. An online survey was conducted from tenth to twentieth of September 2020 to record the data. MATERIAL AND METHODS: A self-designed questionnaire link, using “Google form” was sent to the students via social networks. A total of 589 participants shared their complete information. The simple percentage distribution was employed to evaluate the learning status of the students. RESULTS: During the lockdown period, >70% of the students were engaged in online classes, most commonly by using the Zoom app. The majority of the students were using WIFI as an internet source to attend online classes. Students have been suffering from various problems related to anxiety, stress, economic crises, poor internet connectivity, deprivation of study materials, required e-learning accessories, and an unsuitable study environment. Mainly, students from remote areas and middle income families suffered enormously. Among those participants, who were able to attend the online classes, the majority of students (70%) were dissatisfied with the ongoing online classes. Only 23.3% of the participants suggested the feasibility of online classes in the near future. CONCLUSION: Our study recommended that training teachers and students about online classes might create effectiveness toward e-learning. The government needs to provide free internet services to the remote areas and the poor students since in the current scenario, huge numbers of the population are struggling with the economic burden.

Dengue virus (DENV) is spread mostly by biting by the infected female mosquitoes of the species Aedes aegypti, that are commonly found in tropical and subtropical zones of globe. Some studies have shown that nearly fifty percent of the globe are susceptible to DENV. Most infections by DENV are asymptomatic. Clinical infections vary from mild fever to serious diseases including hemorrhagic fever and shock syndrome. The main objective of this study was to estimate DENV infection by rapid diagnostic (RDTs) kit methods in a tertiary care setting. This retrospective study was done at Crimson Hospital, Butwal, Nepal from June to November 2019. Serum samples of all dengue fever suspected patients were tested for DENV antigen as Dengue nonstructural protein 1(NS1) and DENV specific antibodies as IgM and IgG by using World Health Organization Good Manufacturing Practices (GMP) certified rapid solid phase immunochromatographic method. All laboratory test results were tabulated by using MS-Excel and analyzed by statistical package for the Social Sciences software version 20. Out of 821 samples tested, 518 were positive, including 322 (62.16%) reactive for dengue NS1 Protein, 121 (23.35%) for IgM, 62 (11.96%) for IgG and 13 (2.50%) were positive for both IgG and IgM antibodies. Our study showed high prevalence of dengue infection during monsoon to post-monsoon and the infection rate was higher in males (71.72%) than in females (53.36%). According to our findings, DENV infection is prevalent in Butwal, Nepal. Early diagnosis, better case management, faster public health response and effective health policy towards the control of mosquito vectors may reduce the dengue burden and must be implemented in Nepal.

The disease COVID-19 is brought on by the acute respiratory syndrome coronavirus 2 (SARS-CoV-2) First appeared in China in December 2019 and quickly spread around the world after being declared a worldwide pandemic by the World Health Organization in March 2020. COVID-19, Medical Laboratory Professionals, SARS-COV-2, Diagnostic, Importance and difficulties for testing were the selected terms to search the databases of PubMed and Google Scholar for previously published material. Many diagnostic tests are applied in corona virus detection like Droplet Digital PCR (ddPCR), Multiplex PCR, Loop-mediated Isothermal Amplification (LAMP) and more. There is a lack of availability of molecular and serologic tests that have been clinically validated or authorized by national or international regulatory bodies. Clinical laboratory experts are tackling threats to our global defense and wellness, including infectious diseases. The opportunity to express gratitude to the unsung medical laboratory heroes and COVID0-19 pandemic allies is now greater than ever. Each year, Medical Laboratory Professionals Week should honors those who contribute key diagnostic data that help save lives. This review article explore overall summary on testing methods including Important and Difficult Tasks for Medical Laboratories which will provide good message for better public health matter.

Diabetes is a chronic condition that needs continuing medical treatment and continuing education in patient selfmanagement.To assess and compare the status of oxidative stress, psychological stress, and the economic burden of patients with diabetic and diabetic hypertension. The research was performed on 150 subjects. The present study shows that the diabetes patients in comparison to control subjects have higher mental stress pertaining to hospital anxiety and distress and signicant economic distribution towards medical expenditure
