Yarsagumba Collection and Marketing: a Key Income Source of People in Api Nampa Conservation Area, Darchula, Nepal

Yarsagumba the Himalayan gold rush is the major part of the economy of the himalayan people in the Darchula distict. Our study was conducted in Khandeshwori region of the the Darchula district to quantify the contribution of Yarsagumba on the total household income of the harvester and to reveal the problems releated to its harvesting and selling. Income from Yarshagumba accounted upto 68% in this region. Geo-physical problems were observed most during collection along with significant conflicts and lower productivity. Price variation is the major market problem of those Yarshagumba harvesting peoples. Social factors like family size, adult members and educational factors have significant impact in total collection and income. The highest price obtained was Rs.18408.33, average price was Rs.15308.33 and the lowest price was Rs. 10205. Benefit to cost or expenses (BC) ratio found in research area was 5.13. Having sharp eye vision school children were taken for the collection and have to leave school for time. Although the data is emerging on medicinal use and market of Yarshagumba little systematic research has explored village level harvesting practice and socioeconomic impacts, especially in this region of Nepal

An Experimental and Computational Study of 2-(3-Oxo-3H-benzof chromen-1-ylmethoxy)-Benzoic Acid Methyl Ester

The various methods for studying polarities are based on the use of probe molecules, whose molecular spectral profile is significantly affected by the polarity of the medium. The absorption and emission spectra and dipole moments (µg and µe) of 2-(3-oxo-3H-benzofchromen-1-ylmethoxy)-benzoic acid methyl ester (2BME) are studied in solvents of different polarities at room temperature. The determination of dipole moments by solvatochromic shift using various relations and the change in dipole moment (�µ) were determined using Stokes shift with the variation of the solvent polarity parameter (ET N). The value of µe greater than µg indicating that the probe is more polar in the higher state. DFT and TDDFT theoretical analysis of dipole moment in the vacuum and with solvent, solvent accessible surface (SAS) and molecular electrostatic potential (MEP) are also performed. © 2017, Springer Science+Business Media, LLC

Methylation analysis and diagnostics of Beckwith-Wiedemann syndrome in 1,000 subjects.

BACKGROUND: Beckwith-Wiedemann syndrome (BWS), a congenital overgrowth disorder with variable expressivity and a predisposition to tumorigenesis, results from disordered expression and/or function of imprinted genes at chromosome 11p15.5. There are no generally agreed clinical diagnostic criteria, with molecular studies commonly performed to confirm diagnosis. In particular, methylation status analysis at two 11p15.5 imprinting control centres (IC1 and IC2) detects up to 80% of BWS cases (though low-level mosaicism may not be detected). In order to evaluate the relationship between the clinical presentation of suspected BWS and IC1/2 methylation abnormalities we reviewed the results of >1,000 referrals for molecular diagnostic testing. RESULTS: Out of 1,091 referrals, 507 (46.5%) had a positive diagnostic test for BWS. The frequency of tumours was 3.4% in those with a molecular diagnosis of BWS. Previously reported genotype-phenotype associations with paternal uniparental disomy, IC1, and IC2 epimutation groups were confirmed and potential novel associations detected. Predictive values of previously described clinical diagnostic criteria were compared and, although there were differences in their sensitivity and specificity, receiver operating characteristic (ROC) analysis demonstrated that these were not optimal in predicting 11p15.5 methylation abnormalities. Using logistic regression, we identified clinical features with the best predictive value for a positive methylation abnormality. Furthermore, we developed a weighted scoring system (sensitivity 75.9%, and specificity 81.8%) to prioritise patients presenting with the most common features of BWS, and ROC analysis demonstrated superior performance (area under the curve 0.85, 95% CI 0.83 to 0.87) compared to previous criteria. CONCLUSIONS: We suggest that this novel tool will facilitate selection of patients with suspected BWS for routine diagnostic testing and so improve the diagnosis of the disorder.We thank Action Medical Research and the Cambridge NIHR Biomedical Research Centre for financial support.This is the final published version.

Whole shoot mineral partitioning and accumulation in pea (Pisum sativum)

Several grain legumes are staple food crops that are important sources of minerals for humans; unfortunately, our knowledge is incomplete with respect to the mechanisms of translocation of these minerals to the vegetative tissues and loading into seeds. Understanding the mechanism and partitioning of minerals in pea could help in developing cultivars with high mineral density. A mineral partitioning study was conducted in pea to assess whole-plant growth and mineral content and the potential source-sink remobilization of different minerals, especially during seed development. Shoot and root mineral content increased for all the minerals, although tissue-specific partitioning differed between the minerals. Net remobilization was observed for P, S, Cu, and Fe from both the vegetative tissues and pod wall, but the amounts remobilized were much below the total accumulation in the seeds. Within the mature pod, more minerals were partitioned to the seed fraction (\u3e75%) at maturity than to the pod wall for all the minerals except Ca, where only 21% was partitioned to the seed fraction. Although there was evidence for net remobilization of some minerals from different tissues into seeds, continued uptake and translocation of minerals to source tissues during seed fill is as important, if not more important, than remobilization of previously stored minerals

Boosting Inverter Without electrolytic capacitor In a Single Stage Conversion

This paper introduces a high-gain single-stage boosting inverter for alternative energy generation. As compared to the traditional two-stage approach, the SSBI has a simpler topology and a lower component count. One cycle control was employed to generate ac voltage output. This paper presents theoretical analysis, simulation and experimental results obtained from a 200 W prototype. The experimental results reveal that the proposed SSBI can achieve high dc input voltage boosting, good dc–ac power decoupling, good quality of ac output waveform, and good conversion efficiency. Keywords - OCC-One cycle control, TI-tapped inductor, SSBI- single-stage boosting inverte

A double blind, randomized, placebo controlled, phase IV, proof-of-concept, comparative study to evaluate the efficacy and safety of Swasawin asthaloc tablets when given as add-on therapy in patients suffering from mild to moderate persistent bronchial asthma

Background: Asthma, known as “Tamaka Shwasa” in Ayurveda, as a chronic inflammatory disorder of the airways associated with increased airway hyper-responsiveness, recurrent episodes of wheezing, breathlessness, chest tightness and coughing, particularly at night/early morning. The key component to improving control and preventing attacks is the avoidance of triggers. Swasawin Asthaloc tablet, a polyherbal proprietary medication, is claimed to be effective in asthma. The Objective of the study was to evaluate the safety and efficacy of Swasawin Asthaloc tablets when given as add-on therapy to patients suffering from mild to moderate persistent bronchial asthma.Methods: The study was initiated after receiving Institutional Ethics Committee approval. Patients suffering from mild-to-moderate persistent bronchial asthma were randomized to 2 study groups after written informed consent process for 6 months. Group I received the study medication Swasawin Asthaloc tablet (1 tablet twice daily) in addition to regular anti-asthmatic medications (inhaler ± oral medications). Group II received Placebo tablets in a similar dose as add-on therapy. The study efficacy parameters included spirometry, breath holding time (BHT), Asthma symptom score and Ayurvedic Asthma symptom score.Results: 60 patients were enrolled in the study, of which 50 patients completed the study. In case of spirometry, both FEV1 and PEFR values showed statistically significant improvement at the end of 6 months therapy. Significant improvement in the Breath Holding Time (BHT), Ayurvedic Asthma symptom score and Asthma symptom score was observed in the active group as compared to the baseline (p <0.001).Conclusions: Add-on therapy with Swasawin Asthaloc tablets helped in reducing bronchial inflammation and improving asthmatic symptoms by virtue of its anti-inflammatory, bronchodilatory and antihistaminic properties. Hence it can be used as add-on therapy in patients with mild-to-moderate persistent bronchial asthma and may decrease the need for rescue medications especially steroids

Fat feeding potentiates the diabetogenic effect of dexamethasone in Wistar rats

<p>Abstract</p> <p>Background</p> <p>The role of cortisol and its increased action/availability is implicated in the pathogenesis of insulin resistance associated with obesity and metabolic syndrome but the mechanism of increased action/availability is not known. Availability of several other lipophilic hormones, drugs and pollutants are also reported to be increased in obesity. Increased lipids in the circulation are reported to alter the fluidity and permeability of membranes. Hyperlipidemia is also reported to alter the pharmacokinetics and pharmacodynamics of lipophilic molecules and also membrane fluidity and permeability. In this context we assumed that the hyperlipidemia associated with human obesity might play a role in the altered action/availability of cortisol and this in turn might have initiated the metabolic complications. To evaluate our assumption we have administered dexamethasone [low [50 μg/kg/day] or high [250 μg/kg/day] dose] to high-fat [coconut oil & vanaspati] fed rats and the results were compared with rats administered with either dexamethasone or high-fat.</p> <p>Results and Discussion</p> <p>Within two weeks, the rats co-administered with high-fat and dexamethasone developed severe hyperglycemia, hyperlipidemia and insulin resistance compared to rats treated either of them alone. High-fat fed rats treated with higher dose of dexamethasone were presented with severe hyperglycemia, insulin resistance and also severe glycosuria. The hyperlipidemia caused by high-fat feeding might have altered the transport and distribution of dexamethasone, probably by altering the physical state of membranes and transport proteins.</p> <p>Conclusion</p> <p>From the results obtained, it can be speculated that the altered lipid and cortisol metabolism could affect one another, forming a vicious cycle.</p
