Farmers\u27 Perception on the Performance of Different Rice Varieties in Kapilvastu District, Nepal
Rice is the major staple food crop in Nepal. To date, several rice varieties have been developed and released in Nepal. However, rice production is far below in comparison with its production potential. A household survey was conducted in Bangaganga municipality of Kapilvastu district in 2018 to assess farmers\u27 perception on performance of four different rice varieties (Radha-4, Ramdhan, Gorakhnath, and Sawa). The data were collected from a total of 120 rice farmers (randomly selected) using the interview schedule and analyzed using descriptive statistics, Likert scale, and indexing technique. Statistical analysis showed that the Ramdhan variety had the highest yield (4.95 t/ha), whereas Radha-4 had the lowest yield (3.15 t/ha). The most disease and drought-tolerant variety, as perceived by the farmers, was Radha-4. Smut and Khaira were perceived as the primary diseases whereas Brown planthopper and Rice Gundhi bug were the most important insects of all studied rice varieties. The study recommended that the plant breeders should focus on developing site-specific rice varieties to meet the multiple concerns of the farmers, such as higher yield and stress-tolerant. The farmers should be made aware of varietal selection and crop pest management techniques via training programs, which further helps to reduce the yield gap between farmers\u27 field and research field
Quantitative nucleotide level analysis of regulation of translation in response to depolarization of cultured neural cells
Studies on regulation of gene expression have contributed substantially to understanding mechanisms for the long-term activity-dependent alterations in neural connectivity that are thought to mediate learning and memory. Most of these studies, however, have focused on the regulation of mRNA transcription. Here, we utilized high-throughput sequencing coupled with ribosome footprinting to globally characterize the regulation of translation in primary mixed neuronal-glial cultures in response to sustained depolarization. We identified substantial and complex regulation of translation, with many transcripts demonstrating changes in ribosomal occupancy independent of transcriptional changes. We also examined sequence-based mechanisms that might regulate changes in translation in response to depolarization. We found that these are partially mediated by features in the mRNA sequence—notably upstream open reading frames and secondary structure in the 5′ untranslated region—both of which predict downregulation in response to depolarization. Translationally regulated transcripts are also more likely to be targets of FMRP and include genes implicated in autism in humans. Our findings support the idea that control of mRNA translation plays an important role in response to neural activity across the genome
Medical abortion in Nepal: a qualitative study on women's experiences at safe abortion services and pharmacies.
BACKGROUND: Although Nepal legalised abortion in 2002, a significant number of women continue to access unsafe abortions. An estimated 60% of all abortions performed in 2014 were unsafe, with unsafe abortion continuing to be a leading contributor to maternal mortality. Despite medical abortion access being solely permitted through government accredited safe abortion services, medical abortion pills are readily available for illegal purchase at pharmacies throughout the country. METHODS: Utilising an Assets Focused Rapid Participatory Appraisal (AFRPA) research methodology, underpinned by a health information pyramid conceptual framework, this qualitative exploratory study collected data from in-depth, open-ended interviews. The study explored the medical abortion and sexual and reproductive health experiences of ten women who accessed medical abortion through an accredited safe abortion service, and ten women who accessed unsafe medical abortion through pharmacies. RESULTS: Thematic content analysis revealed emerging themes relating to decision-making processes in accessing safe or unsafe medical abortion; knowledge of safe abortion services; and SRH information access and post-abortion contraceptive counselling. Findings emphasised the interconnectivity of sexual and reproductive health and rights; reproductive coercion; education; poverty; spousal separation; and women's personal, social and economic empowerment. CONCLUSIONS: While barriers to safe abortion services persist, so will the continued demand for medical abortion provision through pharmacies. Innovated and effective harm reduction implementations combined with access and information expansion strategies offer the potential to increase access to safe medical abortion while decreasing adverse health outcomes for women

Selective Breeding to Improve Productive and Reproductive Performances and Survivability of Indigenous Sakini Chicken
Indigenous chickens are quite popular in Family Poultry Production System (FPPS) in Nepal, but are constrained with their low productive performance. The present study evaluated the productive and reproductive performance of Sakini chicken in different filial generations and sexes. In addition, research also aimed at understanding the effect of generations on above performances. Initially, base populations (G-0) of Sakini were maintained by collecting eight weeks old birds from different agro-ecologial zones of Nepal. Performance of the birds of G-0 was evaluated based on weekly body weight (12-24 weeks), laying performance, fertility, hatchability, hatch weight and survivability. Selected birds of base population (G-0) were used to produce first (G-1), second (G-2) and third (G-3) generations through selective breeding in each generation. Similarly, body weights at hatching, 12 weeks, 16 weeks, 20 week and 24 weeks were significantly (p<0.001) improved from G0 to G3 and were also significantly (p<0.001) differ for sex (males were always heavier than females). Likewise, there was significant (p<0.05) improvement in egg production (per hen per year), age at first lay (days), body weight at sexual maturity, egg number and egg weight at 90 days of laying in progressive generations. Fertility, hatchability and survivability significantly (p<0.05) improved in selected generations in comparison to base population, whereas, no significant difference was obtained within the different selected population. Thus, indigenous Sakini chicken under this experiment performed better with respect to survivability, fertility and hatchability in later generations that provides ample scope of advancing selective breeding activities within the indigenous population in order to bring significant improvement in the overall productive performance of Sakini chicken in Nepal
Protein associated with SMAD1 (PAWS1/FAM83G) is a substrate for type I bone morphogenetic protein receptors and modulates bone morphogenetic protein signalling
Bone morphogenetic proteins (BMPs) control multiple cellular processes in embryos and adult tissues. BMPs signal through the activation of type I BMP receptor kinases, which then phosphorylate SMADs 1/5/8. In the canonical pathway, this triggers the association of these SMADs with SMAD4 and their translocation to the nucleus, where they regulate gene expression. BMPs can also signal independently of SMAD4, but this pathway is poorly understood. Here, we report the discovery and characterization of PAWS1/FAM83G as a novel SMAD1 interactor. PAWS1 forms a complex with SMAD1 in a SMAD4-independent manner, and BMP signalling induces the phosphorylation of PAWS1 through BMPR1A. The phosphorylation of PAWS1 in response to BMP is essential for activation of the SMAD4-independent BMP target genes NEDD9 and ASNS. Our findings identify PAWS1 as the first non-SMAD substrate for type I BMP receptor kinases and as a novel player in the BMP pathway. We also demonstrate that PAWS1 regulates the expression of several non-BMP target genes, suggesting roles for PAWS1 beyond the BMP pathway
Abortion in Nepal: perspectives of a cross-section of sexual and reproductive health and rights professionals.
BACKGROUND: Globally, women face many barriers in the attainment of sexual and reproductive health and rights (SRHR). Since 2002, the legalisation of abortion in Nepal has seen significant progress in the expansion of safe abortion and family planning services. METHODS: This qualitative, exploratory study was conducted in 2014 and uses nine in-depth, open-ended interviews with a cross-section of SRHR professionals, to explore their perspectives on abortion in Nepal. The study was underpinned by the Assets Focused Rapid Participatory Appraisal (AFRPA) research methodology and used the health information pyramid conceptual framework. RESULTS: Thematic content analysis revealed emerging themes relating to barriers to access and uptake of skilled safe abortion services and post-abortion family planning. Findings also emphasised current practical and legal components relating to the provision of medical abortion through pharmacies and highlighted issues of sex-selective abortion within the predominantly patriarchal society. CONCLUSION: Effective and ongoing sector-wide monitoring and evaluation of safe abortion services and their staff is essential for women in Nepal to have adequate access to effective and efficient safe abortion services, access to contraception and sexual and reproductive health (SRH) information post-abortion and to ensure adherence to current Safe Abortion Policy. It is critical that the unsafe (less and least safe) provision of medical abortion through pharmacies and sex-selective abortion continues to be investigated and that innovative strategies are formulated to ensure the cultural, reproductive and sexual health and rights of Nepali women are realised
PCR Based Genotyping of Lulu Cattle of Nepal for A1, A2 Type Beta-caseins
Lulu is an indigenous breed of cattle (Bos taurus) found in high altitude regions of western Nepal. Population of Lulu cattle has been declining due to introgression with other exotic breeds to increase milk productivity. Here we aimed at finding potential approach for conserving Lulu cattle and its assets by studying the milk contents and investigating which variant of beta-casein protein is present in this breed. Beta caseins are an abundant protein in cow milk with A1 and A2 being the most common genetic variants of this protein. Consumption of A1 type of milk has numerous health-related complications whereas A2 type of milk has numerous human health promoting factors. We used restriction fragment length polymorphism (RFLP) for determining the A1 and A2 variant of beta casein in Lulu cattle. For performing DNA extraction, we collected (n = 18) blood samples of Lulu from Mustang and (n=17) Nepal Agriculture research council farm. The amplified fragments in 3% agarose at 251bp and 213bp respectively confirmed the presence of both A1 and A2 gene in Lulu; however, A2 was of greater abundance. Our study indicated that Lulu has A2 variant of beta-casein predominantly. The gene frequency of A1A1 is 0, A1A2 is 0.06 and A2A2 is 0.94. We further found that the allele frequency of A1 and A2 is 0.03 and 0.97 respectively. We designed special primer for sequencing CSN2 genes since A2 type beta casein gene was predominantly seen on Lulu. The sequencing result further supports our RFLP result as most of our samples have “C” nucleotide SNP in amplified CSN2 gene sequence. The Chi-square value of the current study is 0.04 which supports Hardy-Weinberg equilibrium inferring that Lulu cattle are still in the pure state, where there is no genetic introgression with the exotic breed for the sake of improvement of productivity
