How does transportation facilitate regional economic development?:A heuristic mapping of the literature
Despite a growing body of literature, the relationship between transport investment and regional economic development remains elusive. Individual studies highlight certain aspects but neglect others, and yet do not add up to a holistic framework. This paper engages with this gap by developing a holistic conceptual framework based on the synthesis of the literature. A list of variables and relationships were extracted and classified into a broad framework representing common elements of a regional economic system. Then, a causal loop diagram (CLD) was produced as a conceptual model by employing a system dynamics method that captures the interaction of the elements. The conceptual model reveals that the underlying mechanisms of regional economic development represent a complex and dynamic process engaging multiple factors, causalities, and temporal dynamics. Transport investment improves the attractiveness of regions and generates economic activities, reinforcing further investments, thereby fostering regional GDP and urban growth. The conditions of interregional transport infrastructure determine where cities can emerge and grow, and urban transport infrastructure conditions guide how big (population) and wide (area) a city can become. Three additional soft policies (urban transport, urban policies, and institutions and innovation) influence the attractiveness of regions and their economic activities. The time and scales of the policy inputs may produce different outcomes, i.e., city(ies) size and regional GDP, leading to income inequality across regions. We conclude that the generated conceptual model offers a distinct contribution by originally mapping the links between different studies and provides an overarching framework for further explorations
Simulating the Storm Environment Responsible for Nepal\u27s First Observed Tornado
A high-resolution numerical forecast model was used to simulate the meteorological conditions leading up to the March 31st, 2019 severe weather event that produced Nepal\u27s first-ever observed tornado. The sparse meteorologic observations in the region capturing the storm environment limit the ability to anticipate another similar situation should the particular set of conditions present themselves again. This study presents a multifaced view of the storm environment through 1) a synoptic perspective provided by the Global Data Assimilation System (GDAS) reanalysis dataset and 2) a trio of progressively higher resolution one-way nested simulations (12 kmâ4kmâ1km) driven by GDAS boundary conditions to more closely examine the storm-scale environment. GDAS data and numerical simulations revealed moderately strong instability throughout the region with CAPE values between 1000 and 2000 J kgâ1 Kâ1 and lifted index values between â4 and â7. Vertical wind profiles featuring little directional shear and moderate velocity shear yielded shear-based convective indices that suggested slight potential for rotating supercell thunderstorms. Within this environment, the 1-km simulation produced strong, rotating convection in nearly the same location and at nearly the same time as the observed tornadic storm. Lastly, an assessment of the limited number of observed historical tornadic events in the region showed that with amply convective available potential energy, the 2019 Nepal tornado environment stood out for the limited vertical directional wind shear present
Does Nepalâs Climate Change Adaptation Policy and Practices Address Poor and Vulnerable Communities?
Climate change (CC) impact, adaptation practices and policies are an emerging area of research and development in Nepal. Many households were deeply affected by, climatic variability and natural disasters coupled with a decade-long conflict, leaving them with few options to cope with CC in Nepal. The study was done through reviewed CC related policies and programs initiated at the national to local level. Additionally, study was conducted to analyze different CC adaptation programs and practices in different eco-region from Himalaya to Inner Terai region of center and western Nepal through shared learning dialogue, field observation, key informant interview, regional and district level consultative workshop and focus group discussion. To address the issues of CC, different government and nongovernment institutions have initiated its adaptation programs in Nepal. NAPA and LAPA- Nepal highlighted the adaptation practices and adaptation framework from national to local level. These national programs initiatives have been endorsed by the GoN (Government of Nepal) through the promulgation of CC Policy Nepal 2011. The policy has focused on interdisciplinary approach with 80% funds allocated at the local level particularly for poor and vulnerable groups. Some district level offices have initiated CC adaptation activities such as construction of water harvesting pond for irrigation, water source protection, agroforestry practices and training on CC adaptation and mitigation. Similarly, in some project supported districts, community level and VDC level five year local adaptation plans have been prepared. However, it is observed that there is a big gap in institutional arrangement, capacity to implement and mechanisms for adaptation programs at local level and poor communities. It was also observed that different GOs programs and NGOs were involved to improve the livelihood of the poor and vulnerable communities through pro-poor programs at local level which resulted improve CC adaptation capacity. It is suggested that CC policy in Nepal be formulated with holistic approach, institutionalized implementing mechanism and focus on livelihood improvement of the poor and vulnerable communities that have joint environmental, social or economic benefits.

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 âCâ 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
The role of CD44 and ERM proteins in expression and functionality of P-glycoprotein in breast cancer cells
© 2016 by the authors. Multidrug resistance (MDR) is often attributed to the over-expression of P-glycoprotein (P-gp), which prevents the accumulation of anticancer drugs within cells by virtue of its active drug efflux capacity. We have previously described the intercellular transfer of P-gp via extracellular vesicles (EVs) and proposed the involvement of a unique protein complex in regulating this process. In this paper, we investigate the role of these mediators in the regulation of P-gp functionality and hence the acquisition of MDR following cell to cell transfer. By sequentially silencing the FERM domain-binding proteins, Ezrin, Radixin and Moesin (ERM), as well as CD44, which we also report a selective packaging in breast cancer derived EVs, we have established a role for these proteins, in particular Radixin and CD44, in influencing the P-gp-mediated MDR in whole cells. We also report for the first time the role of ERM proteins in the vesicular transfer of functional P-gp. Specifically, we demonstrate that intercellular membrane insertion is dependent on Ezrin and Moesin, whilst P-gp functionality is governed by the integrity of all ERM proteins in the recipient cell. This study identifies these candidate proteins as potential new therapeutic targets in circumventing MDR clinically
âAgents-in-focusâ and âAgents-in-contextâ: The strong structuration analysis of central government accounting practices and reforms in Nepal
Drawing on Stonesâ (2005) strong structuration theory, the paper unfolds why and how the key stakeholders of central government accounting in Nepal are involved in the reproduction of routinised accounting practices, resisting the externally-propagated changes. Government accountants (the agents-in-focus) through their capability to control the budget routines have enjoyed a powerful social position in their positionâpractice relations with the agents-in-context, i.e. professional accountants and international consultants, higher-level officers and administrators, auditors, and politicians. Social position along with historically-imbued dispositions and their conduct and context analysis have enabled government accountants to strategically exercise their agency. Government accountants have articulated duality and a dialectic relation with the agents-in-context, which have resulted in the reproduction of everyday accounting practice and the resistance to the World Bank-led reforms, such as accrual accounting and, more recently, the Cash-Basis IPSAS
Counselling-based psychosocial intervention to improve the mental health of abused pregnant women: A protocol for randomised controlled feasibility trial in a tertiary hospital in eastern Nepal
© 2019 Author(s). Published by BMJ. Introduction The strong correlation between domestic and family violence (DFV) and mental health has been well documented in studies. Pregnancy is a period when both DFV and mental distress tend to occur and/or accentuate. Although limited, available evidence from developed countries has shown continual support and education as psychological first aid that can reduce DFV and improve mental health. However, there is significantly less number of studies from resource-constrained countries; thus, there continues to be a substantial gap in knowledge and awareness regarding effective interventions for DFV. Methods and analysis A two-arm randomised trial with a nested qualitative study has been planned to assess feasibility and treatment effect estimates of a counselling-based psychosocial intervention among pregnant women with a history of abuse. A total of 140 pregnant women who meet the inclusion criteria will be recruited into the study. Block randomisation will be used to allocate women equally into two groups. The intervention group will receive a counselling session, an information booklet and continuous support by a researcher, while women in the control group will receive contact information of local support services. Feasibility measures, such as rates of recruitment, consent and retention, will be calculated. Qualitative interviews with participants and healthcare providers will explore the acceptability and usability of the intervention. Outcome measures, such as psychological distress, quality of life, social support and self-efficacy, will be measured at baseline, 4 weeks postintervention and 6 weeks postpartum. Ethics and dissemination This study has obtained ethical approval from the Griffith University Human Research Ethics Committee, the Nepal Health Research Council and the Institutional Review Board of a tertiary hospital in Dharan, Nepal. The findings will be disseminated via peer-reviewed publications and conference presentations and will be used to inform a future multicentre trial
Tissue localization of collagenase and leucine aminopeptidase in the bovine filarial parasite Setaria cervi
BACKGROUND: Like other helminth proteases, filarial proteases have also been shown to require for parasite survival inside the host and mediate various physiologic processes such as tissue invasion, feeding, embryogenesis and host immune evasion. Many of these proteases have shown potential for vaccines and chemotherapeutic agents against active filarial infections. Setaria cervi is a bovine filarial parasite and serves as a good parasite model for the studies in lymphatic filariasis. Recently, a 175 kDa collagenase and leucine aminopeptidase (LAP) have been purified and characterized from the bovine filarial parasite S. cervi and shown to be potential vaccine candidate and diagnostic marker, respectively for human lymphatic filariasis. However, their tissue localizations and putative roles in the parasite biology have not yet been examined and thus remain unclear. Therefore, the current study attempts to localize and explore the putative roles of these two enzymes in S. cervi. METHODS: The tissue distributions of 175 kDa collagenase and leucine aminopeptidase in S. cervi were examined by immunohistochemical and histochemical methods, respectively. Immune sera obtained from the jirds immunized with collagenase served as primary antibody, rabbit anti-mouse IgG-HRP conjugate as secondary antibody and DAB as the substrate for the immunostaining of collagenase. Leu-ÎČNA was used as the substrate for the histochemical staining of LAP. RESULTS: Both the collagenase and LAP were present in the body wall; however, they differ in their distribution pattern in different layers of body wall. Collagenase was mainly localized in epicuticle, cuticle, syncytial hypodermis and the nerve cord region whereas LAP was more concentrated in epicuticle, longitudinal muscle layers and almost absent or very faintly stained in syncytial hypodermis and nerve cord region. Both collagenase and LAP showed their common distributions in intestine, uterus and mature eggs, growing embryos and mf. Very strong immunostaining of collagenase in the outer body surface of the parasite indicates its major role in host-parasite relationship whereas the presence of LAP in muscular region suggests its role in tissue remodeling. The common presences of collagenase and LAP in the S. cervi intestine, ovary, uterus, eggs and mf suggest that they also have collaborative roles in molting, nutrition and embryogenesis. The data obtained on their immunological characterizations and their presence in important parasite organs give strong indication that they are critical for the survival of filarial parasite and thus can be good vaccine candidates and/or diagnostic markers for human lymphatic filariasis. CONCLUSION: The manuscript reports for the first time the tissue distribution of collagenase and LAP in the bovine filarial parasite S. cervi and discuss their putative roles in vivo. Our findings also open the avenue to examine the roles of these two proteases in vivo, which will require further experiments like using their natural substrates and/or specific inhibitors in each tissues
'We don't see because we don't ask': Qualitative exploration of service users' and health professionals' views regarding a psychosocial intervention targeting pregnant women experiencing domestic and family violence.
INTRODUCTION:Given the relative recency of Domestic and Family Violence (DFV) management as a field of endeavour, it is not surprising that interventions for addressing DFV is still in its infancy in developing countries. In order to maximise the success of an intervention, it is important to know which aspects of the intervention are considered important and helpful by service providers and service users. This study, therefore, examined the acceptability of an antenatal-based psychosocial intervention targeting DFV in Nepal and explored suggestions for improving the program in future. MATERIALS AND METHODS:Intervention participants and health care providers (HCPs) were interviewed using semi-structured interviews. Data were audio-recorded and thematic analysis was used to analyse the data. Final codes and themes were identified using an iterative review process among the research team. RESULTS:Themes emerging from the data were grouped into domains including perceptions towards DFV, impact of the intervention on women's lives and recommendations for improving the program. DFV was recognised as a significant problem requiring urgent attention for its prevention and control. Intervention participants expressed that they felt safe to share their feelings during the counselling session and got opportunity to learn new skills to cope with DFV. The majority of the participants recommended multiple counselling sessions and a continued provision of the service ensuring the intervention's accessibility by a large number of women. DISCUSSION:This is the first study to document the perspectives of women and HCPs regarding an antenatal-based intervention targeting psychosocial consequences of DFV in Nepal. There was a clear consensus around the need to engage, support and empower victims of DFV and the intervention was well received by the participants. Ensuring good mental health and wellbeing among victims of DFV requires work across individual, organisational and community levels
Complications of Percutaneous Nephrolithotomy and their Management
Introduction: Increasing global prevalence of nephrolithiasis has resulted in the development of new minimally invasive techniques and has also led to the resurgence of established methods such as percutaneous nephrolithotomy (PCNL). This procedure is now recommended as the first option for the treatment of single large or multiple renal stones and those in the inferior calyx. This study was done to assess the complications of PCNL and their management, in our centre.
Methods: Medical records of 144 patients who underwent PCNL at Lumbini Medical College Teaching Hospital, during the last one year were reviewed. The demographic data, size, tract number and location of the calculi, and intraoperative and postoperative complications were evaluated. The various parameters of the calculi were evaluated. Descriptive analysis with frequencies was done.
Results: Complications occurred in 13 (9.02%) patients. Post operative bleeding occurred in seven (4.8%) patients, out of which one patient developed pseudoaneurysms and the other developed arteriovenous fistula. One patient developed hypovolemic shock immediately after surgery. Frequent blockage of urine, excessive drainage of urine from the drain site, hemothorax and colonic perforation was seen in one patient each. One patient had mortality due to post operative bleeding. Complications increased with the number and size of stones and number and site of the tracts.
Conclusion: Percutaneous nephrolithotomy has low complication rate in experienced hands and complications depend upon stone size, history of open stone surgery, tract number, and tract location
