Morpho-physiological and biochemical response of rice (Oryza sativa L.) to drought stress: A review

Global food shortages are caused mainly by drought, the primary driver of yield loss in agriculture worldwide. Drought stress negatively impacts the physiological and morphological characteristics of rice (Oryza sativa L.), limiting the plant productivity and hence the economy of global rice production. Physiological changes due to drought stress in rice include constrained cell division and elongation, stomatal closure, loss of turgor adjustment, reduced photosynthesis, and lower yields. Morphological changes include inhibition of seed germination, reduced tillers, early maturity, and reduced biomass. In addition, drought stress leads to a metabolic alteration by increasing the buildup of reactive oxygen species, reactive stress metabolites, antioxidative enzymes, and abscisic acid. Rice tends to combat drought through three major phenomena; tolerance, avoidance, and escape. Several mitigation techniques are introduced and adapted to combat drought stress which includes choosing drought-tolerant cultivars, planting early types, maintaining adequate moisture levels, conventional breeding, molecular maintenance, and creating variants with high-yielding characteristics. This review attempts to evaluate the various morpho-physiological responses of the rice plant to drought, along with drought stress reduction techniques

Social cohesion among healthcare workers during COVID-19: qualitative research in Indonesia, Nepal, and Vietnam

Existing literature has portrayed numerous challenges that healthcare workers (HCWs) faced during the COVID-19 pandemic, such as heightened risks of transmission against the scarcity of protective equipment, burgeoning workload, and emotional distress, to name a few. However, most studies explored HCWs' experiences at the individual level rather than examining the collective responses. Exploring these experiences could reveal the social-cultural locality of the pandemic while identifying the system constraints in public health emergencies. As part of a mixed-method study on COVID-19 pandemic impacts, we analysed qualitative interview data with 129 HCWs and health-related staff to explore their experiences during the pandemic between 2020 and 2021 in Vietnam, Indonesia, and Nepal. Using Bahers' sociological framework, Community of Fate, we describe five themes reflecting the formation of a community of HCWs and the social cohesion underlying their efforts to survive hardship. The first three themes characterise the HCW community of fate, including (1) Recognition of extreme work-related danger, (2) physical and figurative closures where HCWs restrict themselves from the outside world, (3) chronic ordeals with overwhelming workload and responsibilities, encompassing recurrent mental health challenges. Against such extreme hardship, cohesive bonding and social resilience are reflected through two additional themes: (4) a mutual sense of moral and professional duty to protect communities, (5) the vertical and horizontal convergence among HCWs across levels and among government departments. We discuss these HCWs’ challenges in relation to systemic vulnerabilities while advocating for increasing investment in public health and collaboration across government sectors to prepare for emergency situation

COVID-19 Social Science and Public Engagement Action Research in Vietnam, Indonesia and Nepal (SPEAR): Protocol for a mixed methods study exploring the experiences and impacts of COVID-19 for healthcare workers and vulnerable communities

Background: When the novel coronavirus – SARS-CoV-2 – started to spread globally, there was a call for social and behavioral scientists to conduct research to explore the wider socio-cultural contexts of coronavirus disease 2019 (COVID-19), to understand vulnerabilities, as well as to increase engagement within communities to facilitate adoption of public health measures. In this manuscript, we describe the protocol for a study conducted in Indonesia, Nepal, and Vietnam. In the study, we explore how the COVID-19 pandemic is affecting individuals and their communities. We focus on the wider health and economic impacts of COVID-19, in particular emerging and increased burden on mental health, as well as new or deepened vulnerabilities in the communities. The introduction of vaccines has added another layer of complexity and highlights differences in acceptance and inequalities around access.  Methods: We use mixed methods, combining survey methods and social media surveillance to gain a picture of the general situation within each country, with in-depth qualitative methods to gain a deeper understanding of issues, coupled with a synergistic engagement component. We also include an exploration of the role of social media in revealing or driving perceptions of the pandemic more broadly. Participants include health workers and members of communities from 13 sites across the three countries. Data collection is spread across two phases. Phase 1 is concerned with exploring lived experiences, impacts on working lives and livelihoods, mental health and coping strategies. Phase 2 is concerned with acceptance of COVID-19 vaccines, factors that increase and reduce acceptance, and factors that influence access. Conclusions: We will disseminate findings in multiple ways including short reports and policy briefs, articles in peer-reviewed journals, and digital diaries will be edited into short films and uploaded onto social media sites.</ns3:p

Gender Disparity and UN Peacekeeping Missions: The Case of Nepalese Peacekeepers

The composition of today’s United Nations Peacekeeping forces is dominantly male. There are a limited number of female peacekeepers comprising 4.16% of peacekeeping forces. The safety of female civilians living in conflict areas is jeopardized by this gender unbalance. Focusing on this gender imbalance, this study explores gender disparity inside the Peacekeeping forces of Nepal. Nepalese female peacekeepers constitute 2.12% of the total Nepalese Army peacekeepers and are marginalized in the peacekeeping missions. They are discriminated against, harassed; both blatantly and subtly, and are not taken seriously. This issue of the present day peacekeeping is not considered and is often unexplored. This study unravels the different forms of perpetuating gender disparity and brings the voices of the Nepalese women peacekeepers from the field missions

Nutrient intake of adolescents in rural area of Himachal Pradesh

Background: The nutrient requirements during adolescence are higher than at any other stage of life. Inadequate nutrient intake leads to poor growth, delayed sexual maturation, slow linear growth, anaemia and osteomalacia. Aim &Objective: To assess the nutrient intake of adolescents in 13-15 years belonging to rural area of Shimla district, Himachal Pradesh. Material & Methods: A school based cross-sectional study was conducted during 2014 - 2015 in rural area of Shimla district. Thirty clusters were identified using population proportionate to size sampling method.  A total of 170 adolescents in the age group of 13-15 years studying in government schools were enrolled. Dietary assessment was done using 24h dietary recall method. Results: The percentage deficit in boys for calorie, iron, zinc and calcium intake was found 37.9%, 53.7%, 35.5% and 22.4% respectively as compared to Recommended Dietary Allowances (RDA). The girls had percentage deficit for calorie, iron, zinc and calcium intake as 47.7%, 61.5%, 53.6%, and 43.6 % respectively as compared to RDA. Conclusion: The findings of present study indicate that the nutrient intake of adolescents aged 13-15 years was inadequate

Value chain analysis of arabica coffee (Coffea arabica l.) in Arghakhanchi district of Nepal

AbstractA field survey was conducted during February–May 2022 in Chhatradev rural municipality and Sitganga municipality with the purpose of analyzing the existing value chain of arabica coffee in Arghakhanchi district of Nepal. A sample size of 110 arabica coffee growers, comprising 55 from each municipality, was selected by using three-stage sampling method for interviews that used a pretested questionnaire. To study the value addition and trading aspects, six collectors and pulper operators and two secondary processors were selected. Descriptive statistics was applied to analyze the data. Input suppliers, producers, collectors, pulper operators, secondary processors, traders, and consumers were identified as key players in the coffee value chain. NTCDB, NARC, CDC, AKC, Coffee Zone, Primary Coffee Cooperatives, Central Coffee Cooperative Union Limited, NCPA, financial institutions, and certification agencies were identified as the enabling environment providers in the value chain. The findings showed that the gross margin of one kg each of fresh cherry production, dry parchment production, green bean production, and coffee powder production was NRs. 26.06, NRs. 92.83, NRs. 107.7, and NRs. 215.06, respectively. Value addition from producers to primary processors was NRs. 109.8 per kg, and the value addition from primary to secondary processors was NRs. 445.6 per kg. Similarly, the value addition from secondary processors to consumers was NRs. 480.58 per kg. The research area’s value chain structure or network was determined to be brief and straightforward. Therefore, it is advised to adopt cutting-edge processing and packaging methods to improve the competitiveness of Nepali coffee in the market

Antioxidant and Enzyme Inhibitory Potential of Streptomyces sp. G-18 Grown in Various Media

Streptomyces are bacteria well known for producing bioactive secondary metabolites which are commonly found in diverse habitats. The biosynthesis of metabolites from Streptomyces is influenced by various factors such as the growth medium, environmental conditions, and gene regulation. This study aimed to investigate the influence of different growth media on biomass production and the antioxidant and enzyme inhibitory potential of a crude extract obtained from Streptomyces sp. G-18 isolated from high altitudinal soil of Nepal. The highest dry weight growth was observed in R2YE medium (184 mg/L), followed by R5 (144 mg/L), YEME (38 mg/L), and R5M media (30 mg/L). The crude extract showed notable antioxidant activities against free radicals. The highest alpha-amylase inhibition was observed in the R2YE medium, and worthy lipase and tyrosinase inhibition was observed in the YEME medium. However, only the R2YE medium exhibited inhibitory potential against elastase and acetylcholinesterase, while crude extracts from R5, YEME, and R5 modified did not show any such activity. Overall, our findings suggest that the production of bioactive secondary metabolites in Streptomyces sp. G-18 was significantly influenced by the growth medium. This strain may be a promising source of enzyme inhibitors with potential applications in the pharmaceutical and cosmetic industries

Sexual Intercourse during Pregnancy among Postpartum Women Admitted to the Department of Obstetrics in a Tertiary Care Centre

Introduction: Pregnancy is a time when women's bodies and minds go through a lot of changes. Sexuality is an important part of a woman's health and well-being, and it often changes during pregnancy. Most women admit that their libido changes in some way during pregnancy. However, the sexuality of a pregnant woman is very individual and influenced by a variety of different factors. This is a very important topic that is often taboo, especially in a male-dominated society, and it needs to be explored more. The aim of this study was to find out the prevalence of sexual intercourse among postpartum women admitted to the Department of Obstetrics in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among postpartum women admitted to a tertiary care centre after taking ethical approval from the Institutional Review Committee. The study was carried out from 1 January 2021 to 30 December 2021. Convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 97 pregnant women admitted to the Department of Obstetrics, the prevalence of sexual intercourse was 36 (37.11%) (27.50-46.72, 95% Confidence Interval). A total of 34 (94.44%) were sexually active in the first trimester while 13 (36.11%) and 4 (11.11%) were sexually active in the second trimester and third trimester respectively. Conclusions: The prevalence of sexual intercourse during pregnancy was lower than other studies done in similar settings
