Self Help Groups (SHGs) and Women's Development: A Case Study of the Varanasi District

Development is a multi-dimensional process that affects society in multiple ways. It is well documented that women constitute about half of the world's population but their share in the economy and other development spheres remain neglected. In addition, this large section of population (including Indian women) have been suffering from various disadvantages - lack of accessibility to resources, non-recognition of their economic contribution within the family and society. In order to resolve these emerging challenges, Government of India (GOI) has implemented various programmes and policies since Independence. Among these programmes, Self Help Groups (SHGs) may be considered as a significant initiative of the government as well as the non-governmental organisations (NGOs). These are based on the principle of democratic process of development. The democratic institution provides a platform to the socially and economically deprived sections and encourages them for economic participation. Since the 1970s, SHGs have been working in many states of India and contributing to the development processes. The present paper is an attempt to analyse the contribution of SHGs in women's development in the district of Varanasi in Uttar Pradesh. The impact of these groups on women's development has been analysed by Gender Development Index (GDI), which focused on the male-female differences in terms of longevity of life, knowledge and economic betterment.

A study of the impact of generative AI-based data augmentation on software metadata classification

This paper presents the system submitted by the team from IIT(ISM) Dhanbad in FIRE IRSE 2023 shared task 1 on the automatic usefulness prediction of code-comment pairs as well as the impact of Large Language Model(LLM) generated data on original base data towards an associated source code. We have developed a framework where we train a machine learning-based model using the neural contextual representations of the comments and their corresponding codes to predict the usefulness of code-comments pair and performance analysis with LLM-generated data with base data. In the official assessment, our system achieves a 4% increase in F1-score from baseline and the quality of generated data

Comparison of BTX Profiles and Their Mutagenicity Assessment at Two Sites of Agra, India

In the present study, the concentrations of three volatile organic compounds (VOCs), namely, acronym for benzene, toluene, and xylenes (BTX) were assessed because of their role in the tropospheric chemistry. Two representative sites, a roadside and a petrol pump, were chosen for sample collection. VOCs were collected using SKC-activated charcoal tubes and SKC personal sampler and characterized by gas chromatograph using flame ionization detector. Among BTX, benzene had the highest concentration. At the roadside, mean concentration of benzene, toluene, o-,m-xylene, and p-xylene were 14.7 ± 2.4 μgm−3, 8.1 ± 1.2 μgm−3, 2.1 ± 0.8 μgm−3, and 5.1 ± 1.2 μgm−3, respectively. At the petrol pump, the mean concentrations of benzene, toluene, o-,m-xylene and p-xylene were 19.5 ± 3.7 μgm−3, 12.9 ± 1.1 μgm−3, 3.6 ± 0.5 μgm−3 and 11.1 ± 1.5 μgm−3, respectively, and were numerically higher by a fraction of 2. Monthly variation of BTX showed maximum concentration in winter. Inter-species ratios and inter-species correlation indicated traffic as the major source of BTX. Extracts of samples were positive in both Salmonella typhimurium tester strains TA98 and TA100 without metabolic activation suggesting the presence of direct mutagens in ambient air that can cause both frame-shift and base-pair mutation. The mutagenic response was greater for TA100 than TA98 suggesting greater activity for base-pair mutagenicity than frame-shift mutagenicity and was found to be statistically significant

Method development and validation for acrylamide in potato cutlet by UHPLC-MS/MS

Surge in consumption of healthy and safe foods has challenged researchers to develop sensitive, precise, robust detection and quantification of food contaminants like acrylamide even if they are present in trace. Keeping this in view, a robust and sensitive analytical method was developed and validated for acrylamide quantification in a potato-based food product (potato cutlet), using LC-MSMS with positive electrospray ionization (+ESI). The method consists of adding acrylamide-d3 (deuterium labelled acrylamide) as an internal standard, extraction by modified QuEChERS method with d-SPE clean-up. Extracts were run on a reverse phase C-18 column for analysis by liquid chromatography. The limit of detection (LOD) and limit of quantification (LOQ) were determined as 0.7 and 2.0 μg kg− 1 , respectively, demonstrating the sensitivity of the method for trace detection. The developed method showed excellent results in terms of recoveries (91.0–109.16%), repeatability (RSD 1.8–10.60%), reproducibility (RSD 2.3–11.24%) and robustness (RSD 1.74–4.54%). The repeatability, reproducibility and robustness respectively, show the consistency, accuracy and stability of the developed method. The deviations in ion ratio and retention time were 17.25% and − 0.01 min, respectively. Compared to previous findings, the current study has achieved lower LOD and LOQ levels that reveals the higher sensitivity of this method for acrylamide quantification in potato cutletMinistry of Food Processing Industries, Government of India | Ref.

Plant regeneration from axillary bud, callus and somatic embryo in carnation (Dianthus caryophyllus) and assessment of genetic fidelity using RAPD-PCR analysis

Plant regeneration was achieved from axillary bud, callus and somatic embryos of Dianthus caryophyllus cv.Yellow Dot Com from node and leaf explants cultured on Murashige and Skoog (MS) medium supplemented with plant growth regulators. The explant nodal cutting responded well for direct regeneration while leaf explant was selected for callus induction. The highest number of direct adventitious shoots were achieved with 9.08 μM TDZ and 5.37 μM NAA. The maximum callus induction was achieved with 2.06 μM 2, 4-D and 2.68 μM NAA. The calli derived from MS medium supplemented with 5.37 μM NAA and 2.27 μM TDZ were found to have maximum shoot regeneration potential. The highest number of calli producing shoots and average number of shoots per callus was recorded on MS medium supplemented with 9.12 μM zeatin and 5.07 μM IAA. The calli derived from leaf explants cultured on medium containing 2.06 μM 2, 4-D and 2.68 μM NAA were highly friable, had poor regeneration potential and were selected for cell suspension studies. The cultures were allowed to grow into micro-colonies in liquid medium and subsequently into embryogenic calli on semi-solid and solid MS medium which later differentiated into somatic embryos without growth regulators. Plantlets were obtained from in vitro derived shoots/somatic embryos with 60-80% survival after 30 day of transfer to pots. The plants regenerated from axillary buds, callus and somatic embryos were compared with mother plant to assess genetic fidelity using RAPD and 2.94%, 26.47% and 20.58% variation was observed, respectively

NOVEL APPLICATION OF MIXED HYDROTROPIC SOLUBILIZATION TECHNIQUE IN THE FORMULATION AND EVALUATION OF SOLID DISPERSION OF FLUPIRTINE MALEATE

Flupirtine is an amino pyridine derivative that functions as a centrally acting non-opioid, non-steroidal analgesic. It is a selective neuronal potassium channel opener that also has NMDA receptor antagonist properties. Its muscle relaxant properties make it popular for back pain and other orthopedics uses. In the present investigation, recently developed mixed hydrotropic solid dispersion technology precludes the use of organic solvent and also decreases the individual concentration of hydrotropic agents, simultaneously decreasing their toxic potential. Mixed-hydrotropic solubilisation technique is the experience to increase the solubility of poorly water soluble drugs in the aqueous solution containing blends of hydrotropic agents, which may give synergistic enhancement effect on solubility of poorly water-soluble drugs and to reduce concentrations of each individual hydrotropic agent to minimize their toxic effects due to high concentration of hydrotropic agents. The Flupirtine loaded solid dispersion was prepared by a solvent evaporation technique using sodium benzoate and a niacinamide hydrotropic mixture. The prepared solid dispersions were valuated regarding their solubility, mean particle size, in-vitro drug release. The prepared solid dispersions were found very stable (chemically). The superior dissolution rate due to its reduced particle size may have contributed to the increased oral bioavailability. This study demonstrated that mixed-solvency may be an alternative approach for poorly soluble drugs to improve their solubility and oral bioavailability.

Concise review: Therapeutic potential of flupirtine maleate

Flupirtine is a non-opioid analgesic without antipyretic or antiphlogistic properties. Flupirtine is a centrally acting analgesic but the analgesic action of flupirtine does not depend on any central opioid effect. The fact behind this statement is that the pain-relieving property of flupirtine is not reduced by the opioid antagonistic drug naloxone. Flupirtine has been reported for its neuro-protective properties and possess a selective neuronal potassium channel opener that also has NMDA receptor antagonist properties. Flupertine is transformed into two primary derivatives, 4-fluoro-hippuric acid and the Nacetylated analogue D13223. Both derivatives of are flupirtine pharmacologically active with 30% of the analgesic potency of the parent drug and further oxidized and then conjugated with glycine to form inactive  metabolites, Recently, Flupirtine maleate  has been introduced in Indian market in oral, intravenous and rectal dosage forms. The half life of flupirtine following intravenous administration was 1.8 hours, while the plasma elimination half life in healthy young volunteers following single dose administration of flupirtine by the intravenous, oral and rectal routes was 8.5, 9.6 and 10.7 hours respectively. There is plenty of literature available on the effect of Flupirtine maleate on chronic and acute pain management. These preliminary finding require confirmation in further comparative studies.

Development of a Fast SARS-CoV-2 IgG ELISA, Based on Receptor-Binding Domain, and Its Comparative Evaluation Using Temporally Segregated Samples From RT-PCR Positive Individuals

SARS-CoV-2 antibody detection assays are crucial for gathering seroepidemiological information and monitoring the sustainability of antibody response against the virus. The SARS-CoV-2 Spike protein's receptor-binding domain (RBD) is a very specific target for anti-SARS-CoV-2 antibodies detection. Moreover, many neutralizing antibodies are mapped to this domain, linking antibody response to RBD with neutralizing potential. Detection of IgG antibodies, rather than IgM or total antibodies, against RBD is likely to play a larger role in understanding antibody-mediated protection and vaccine response. Here we describe a rapid and stable RBD-based IgG ELISA test obtained through extensive optimization of the assay components and conditions. The test showed a specificity of 99.79% (95% CI: 98.82-99.99%) in a panel of pre-pandemic samples (n = 470) from different groups, i.e., pregnancy, fever, HCV, HBV, and autoantibodies positive. Test sensitivity was evaluated using sera from SARS-CoV-2 RT-PCR positive individuals (n = 312) and found to be 53.33% (95% CI: 37.87-68.34%), 80.47% (95% CI: 72.53-86.94%), and 88.24% (95% CI: 82.05-92.88%) in panel 1 (days 0-13), panel 2 (days 14-20) and panel 3 (days 21-27), respectively. Higher sensitivity was achieved in symptomatic individuals and reached 92.14% (95% CI: 86.38-96.01%) for panel 3. Our test, with a shorter runtime, showed higher sensitivity than parallelly tested commercial ELISAs for SARS-CoV-2-IgG, i.e., Euroimmun and Zydus, even when equivocal results in the commercial ELISAs were considered positive. None of the tests, which are using different antigens, could detect anti-SARS-CoV-2 IgGs in 10.5% RT-PCR positive individuals by the fourth week, suggesting the lack of IgG response
