    Amaranth improvement in India hither to was concerned with development of high-yielding varieties, and hardly any research efforts have been made for its nutritional improvement. Keeping this in view, at Indian Institute of Horticultural Research two high-yielding amaranth varieties, Arka Samraksha and Arka Varna with high antioxidant activity, low amounts of nitrates and oxalates were developed using modified bulk method of selection from segregating population of the crosses IIHR-4 x IIHR-70 and IIHR-7 x IIHR-30 . Arka Samraksha is a high-yielding (10.9 t/ha in 30-35 days), pulling-type variety with green leaves and stem, antioxidant activity of 499mg (AEAC units) and minimum nitrate content of 27.3 mg and 1.34 g oxalates per 100 g fresh leaf weight. Arka Varna also a pulling type, high-yielding variety (10.6 t/ha in 30-35 days) with green leaves and a pink stem, high antioxidant activity of 417 mg (AEAC units), low nitrate content of 37.6 mg and 1.42 g oxalates per 100 g fresh leaf weight

    Purpose: To evaluate, using ethnomedical data approach, five Indian plants used in traditional medicine for cancer and other diseases for their safety and cytotoxic activity on human lymphocytes.Methods: The antiproliferative effect of the 50, 100 and 200 Ƭg/ml aqueous extracts of five plants (leaves of Phyllanthus niruri, Coleus aromaticus, Azadirachta indica and Camellia sinensis, and driedfruit rind of Garcinia indica) were evaluated in vitro using trypan blue dye exclusion and clonogenic assay methods on two cell lines - Balb/c 3T3 mouse fibroblasts and human peripheral lymphocytes.Results: Among the five plants used traditionally to treat cancer and other infections, two of them (A. indica and C. aromaticus) exhibited cytotoxic effects on lymphocytes. Two other plants (G. indica and P.niruri) exhibited pronounced cytotoxic effects. Another plant (Camellia sinensis) exhibitedcytostimulatory effect (> 50 % cell proliferation). For the plants that are traditionally used in anticancer therapy, there was a correlation between the reported use of these plants and their cytotoxic activity onlymphocytes.Conclusion: The plant extracts of the leaves of P. niruri, C, aromaticus and A. indica, and the dried fruit rind of G. indica are cytotoxic to lymphocytes and this lends some credence to their traditional use for cancer treatment. However, green tea (C. sinensis) is cytostimulatory and safe for consumption

    Objectives: The present study aimed at assessing high school teachersā€™ mental health literacy (MHL) and predictors related to study outcomes.Design: Cross-sectional studyMethods: We employed 460 high school teachers who engaged with adolescents for at least six hours per week with a minimum of five years of teaching experience in southern India. Semi-structured questionnaires were used to assess their MHL. Descriptive analysis and backward logistic regression analysis were performed. A p-value < 0.05 was set as significant.Results: Teachersā€™ MHL on depression was less than desirable; however, they identified 288 (62.6%) adolescents with mental health problems during their career, and 172(59.72%) were referred to mental health professionals. On logistic regression analysis, teachersā€™ educational status, their marital status, teaching a class with an average strength of 31-60 students per class, previous mental health training and having self-efficacy concerning seeking informationon mental health, perceived ability to spread awareness and to provide referrals were found to predict MHL among teachers.Conclusion: Sociodemographic factors including teachersā€™ educational status, average class strength and having had previous mental health training were predictors for MHL among high school teachers. Establishing training programs and referral networks may be key in early intervention among adolescents

    Background: Obstetric haemorrhage accounts for 20-25% of maternal mortality and morbidity. Anti-fibrinolytics are being widely used in field of surgery. It is also used to reduce heavy menstrual blood loss. The aim of this study was to analyse the effectiveness of TXA in reducing blood loss during normal vaginal delivery.Methods: The randomized double-blind control study was done in the Labour ward. It was conducted on 100 women undergoing Normal vaginal delivery. They were allocated to either Study or Control group by randomization. TXA was given during the Third stage of delivery in study group in addition to the routine care whereas the control group had routine care alone. Blood loss was measured in both groups by bag method.Results: The significant of reduction in blood loss calculated from placental delivery to 2hrs. 141.9 ml in study group versus 270.4 ml in control group. Among primi patients, the control group average blood loss was 325ml, the study group avg blood loss was 169ml. Among G2 patients, the control group average blood loss was 248.5ml. The study group average blood loss was 128.25ml. Among G3 patients, the control group average blood loss was 203ml, the study group average blood loss was 115ml.Conclusions: TXA significantly reduced the amount of blood loss during normal vaginal delivery. Thus, TXA can be used safely and effectively in subjects undergoing normal vaginal delivery

    Investigations were carried out to identify the source of resistance in 67 bottle gourd genotypes for gummy stem blight, powdery mildew and cucumber green mottle mosaic virus (CGMMV) diseases, under natural field epiphytotic conditions. The genotypes BG-95 (105.13), BG-114-1 (131.04), BG-114-3 (208.81) and BG-77-6-1 (221.80) were resistant for gummy stem blight with low AUDPC values, while, BG-125-5 (232.22), BG-6-3 found (250.00), BG-125-4 (307.78), BG-8-1 (308.89), BG-125-2 (311.11) and BG-124-2 (423.33) resistant with low AUDPC values for powdery mildew. Further, the two genotypes such as IIHR-19 and BG- 131 showed field level resistance against CGMMV. The selected genotypes based on field evaluation were subjected for artificial screening under glass house conditions. The genotypes, recorded consistent resistant reactions were BG-114-3, BG-77-6-1 and BG-95 for gummy stem blight disease and BG-6-3, BG-8-1, BG-125-4 and BG-125-2 for powdery mildew. The stable and durable source of resistance identified for gummy stem blight and powdery mildew in bottle gourd genotypes will hasten the process of developing resistance varieties in bottle gourd

    High ALDH Activity Identifies Chemotherapy-Resistant Ewing's Sarcoma Stem Cells That Retain Sensitivity to EWS-FLI1 Inhibition

    Cancer stem cells are a chemotherapy-resistant population capable of self-renewal and of regenerating the bulk tumor, thereby causing relapse and patient death. Ewing's sarcoma, the second most common form of bone tumor in adolescents and young adults, follows a clinical pattern consistent with the Cancer Stem Cell model - remission is easily achieved, even for patients with metastatic disease, but relapse remains frequent and is usually fatal.We have isolated a subpopulation of Ewing's sarcoma cells, from both human cell lines and human xenografts grown in immune deficient mice, which express high aldehyde dehydrogenase (ALDH(high)) activity and are enriched for clonogenicity, sphere-formation, and tumor initiation. The ALDH(high) cells are resistant to chemotherapy in vitro, but this can be overcome by the ATP binding cassette transport protein inhibitor, verapamil. Importantly, these cells are not resistant to YK-4-279, a small molecule inhibitor of EWS-FLI1 that is selectively toxic to Ewing's sarcoma cells both in vitro and in vivo.Ewing's sarcoma contains an ALDH(high) stem-like population of chemotherapy-resistant cells that retain sensitivity to EWS-FLI1 inhibition. Inhibiting the EWS-FLI1 oncoprotein may prove to be an effective means of improving patient outcomes by targeting Ewing's sarcoma stem cells that survive standard chemotherapy

    Fog computing security: a review of current applications and security solutions

    Get PDF
    Fog computing is a new paradigm that extends the Cloud platform model by providing computing resources on the edges of a network. It can be described as a cloud-like platform having similar data, computation, storage and application services, but is fundamentally different in that it is decentralized. In addition, Fog systems are capable of processing large amounts of data locally, operate on-premise, are fully portable, and can be installed on heterogeneous hardware. These features make the Fog platform highly suitable for time and location-sensitive applications. For example, Internet of Things (IoT) devices are required to quickly process a large amount of data. This wide range of functionality driven applications intensifies many security issues regarding data, virtualization, segregation, network, malware and monitoring. This paper surveys existing literature on Fog computing applications to identify common security gaps. Similar technologies like Edge computing, Cloudlets and Micro-data centres have also been included to provide a holistic review process. The majority of Fog applications are motivated by the desire for functionality and end-user requirements, while the security aspects are often ignored or considered as an afterthought. This paper also determines the impact of those security issues and possible solutions, providing future security-relevant directions to those responsible for designing, developing, and maintaining Fog systems

    The plant-based immunomodulator curcumin as a potential candidate for the development of an adjunctive therapy for cerebral malaria

    Get PDF
    The clinical manifestations of cerebral malaria (CM) are well correlated with underlying major pathophysiological events occurring during an acute malaria infection, the most important of which, is the adherence of parasitized erythrocytes to endothelial cells ultimately leading to sequestration and obstruction of brain capillaries. The consequent reduction in blood flow, leads to cerebral hypoxia, localized inflammation and release of neurotoxic molecules and inflammatory cytokines by the endothelium. The pharmacological regulation of these immunopathological processes by immunomodulatory molecules may potentially benefit the management of this severe complication. Adjunctive therapy of CM patients with an appropriate immunomodulatory compound possessing even moderate anti-malarial activity with the capacity to down regulate excess production of proinflammatory cytokines and expression of adhesion molecules, could potentially reverse cytoadherence, improve survival and prevent neurological sequelae. Current major drug discovery programmes are mainly focused on novel parasite targets and mechanisms of action. However, the discovery of compounds targeting the host remains a largely unexplored but attractive area of drug discovery research for the treatment of CM. This review discusses the properties of the plant immune-modifier curcumin and its potential as an adjunctive therapy for the management of this complication
