Characterizations of the active ingredients of methanol extract of weaver ant and its analgesic activity in mice

Pain according to WHO has been one of the greatest issues to plague man, in the bid to handle this issue of pain, man has sought to look for other means to reduce pain to its bare minimum. This study is aimed at investigating the analgesic activity of the methanolic extract of the African weaver ant using acetic acid-induced writhing, hot plate method, and formalin-induced pain models in Swiss mice. In the acetic acid test, the methanolic extract of Oecophylla longinoda (OL) was administered orally at 200 and 400 mg/kg body weight while aspirin was administered at 100 mg/kg and tween 80 served as standards. In the hot plate and formalin models, the extract was administered orally at two doses of 200 and 400 mg/kg while pentazocine at 10 mg/kg and tween 80 at 10 mg/kg served as standards. The methanolic extract of OL exhibited significant analgesic activity in all the models, with none less than the standard significant difference (p < 0.05) by increasing the reaction time of the mice after treatment in comparison to the control. The 400 mg/kg extract in the acetic acid-induced writhing response has a percentage inhibition of 52.7%, which shows how well the extract inhibits pain in mice. The methanolic extract significantly reduced pain response in mice, with a p-value of 0.03, 0.02, and 0.001 in all the test models, respectively. OL increased the pain threshold over time and significantly reduced the writhing response that mice experience from acetic acid. Furthermore, pretreatment with OL significantly and dose-dependently decreased the early and late phases of formalin-induced pain in mice. Thus, these findings suggest that the methanolic extract of OL acts on central and peripheral pain pathways.

An analysis of south africa’s readiness for analogue to digital terrestrial television migration

ABSTRACT The 2006 International Telecommunication Union (ITU) Radio World Conference treaty concluded that all countries should migrate from analogue to digital terrestrial television by June 2015, starting with region one countries, comprising Africa, Europe, the Middle East and the Republic of Iran (Agona & Otim, 2012). The purpose of this research was to explore the technology adoption model (TAM) to address challenges associated with digital terrestrial television migration, and analyse the readiness of South Africa to migrate. A quantitative research was conducted in order to determine the relationship between dependent and independent variables. Digital television offers many benefits for broadcasters, network operators, spectrum regulators, and consumers. In most countries, the transition was slower than expected, even though most European countries managed to migrate. The digital migration is not an easy transition and analogue switch-off can also be much more difficult. Studies have shown that analogue switch off (ASO) needs to be carefully planned and well budgeted for, and it also needs a good publicity campaign which must involve all relevant stakeholders, such as broadcasters, viewers, manufacturers, network operators, manufacturers and retailers. Even though studies conducted previously identified obstacles of digital migration to include; a) lack of awareness b) lack of information, c) influence of politics and d) influence of corruption.

Surface modification of anhydrous borax with stearic acid by wet coating method

The wet coating of anhydrous borax powders with stearic acid (SA) to reverse their inherent hydrophilic surface properties was investigated. The coating procedure was based on the results from a previous study that revealed that the stearic acid solution (2 wt. % SA) mixed for 60 minute at 750 rpm on the magnetic stirrer was sufficient for the surface modification of anhydrous borax. For the experiments, stearic acid powders were first dissolved in water at 80 °C. The mixture obtained by adding anhydrous borax powders to this solution was vigorously mixed on a magnetic stirrer to initiation and completion the surface modification. Each of these solutions was then filtered using a filter paper to separate the undissolved particles, and the residue on paper was dried at 50 °C for 48 h until constant weighing was obtained. Wettability has been accepted as a key parameter for success in wet coating treatment. This parameter gained via the experimental characterization technique was used for an evaluation of the powder properties. The degree of wettability of anhydrous borax powders was measured and compared both after their surfaces were coated with stearic acid and after they were treated with water for a certain period of time in an aqueous environment. The stearic acid coating made the powder hydrophobic and this property was highly preserved after washing.

The impact of school-based physical activity programs on academic performance among adolescents in india

Background: Evidence has suggested that school-based physical activity programs (SBPAPs) including structured physical education, extracurricular sports, and activity-based learningenhance memory and other cognitive functions. However, evidence on whether Indian adolescents can achieve improved cognition or increased academic performance also remains scarce. This study aimed to examine the relationship between SBPAPs and academic performance among Indian adolescents. Methods: A cross-sectional, mixed study was carried out from October 2024 to March 2025 in public and private secondary schools in Haryana and Punjab, north India. A total of 300 students aged 13 to 17 years were divided into an intervention group (n = 150) who participated in structured physical activity (PA) of at least 150 minutes per week and a comparison group (n = 150) who were involved in less than 30 minutes of PA per week. Academic performance was assessed in terms of composite scores of core subjects, while the level of PA was measured using the Physical Activity Questionnaire for Adolescents. Independent samples t-tests, one-way analysis of variance (ANOVA), and Pearson’s correlation analysis were all used for quantitative data handling. Qualitative data gathered from focus group discussions and key informant interviews with a subsample (n = 30) were thematically analyzed. Results: There were no significant differences in baseline demographics between the groups (p > 0.05). Compared with the comparison group, the intervention group showed significantly higher academic scores (mean = 76.4%, SD = 7.8; mean = 70.6%, SD = 8.4) with a moderate-to-large effect size (t = 6.30, p < 0.001, d = 0.72). A one-way ANOVA found that academic performance differed significantly among PA intensity levels (F(2,297) = 19.44, p < 0.001). There was a moderate positive correlation between PA levels and academic achievement (r = 0.44, p < 0.01). Qualitative findings corroborated quantitative data, showing that physically active students displayed improved concentration, emotional regulation, and academic motivation. Conclusions: Partaking in structured SBPAPs significantly increases Indian adolescents’ academic performance. These findings imply the necessity of including physical education in the academic curriculum as a low-cost, scalable method for supporting both cognitive growth and educational achievement.

Impact of environment due to sars-cov-2 in india

Before the start of the SARS-CoV-2 (COVID-19) pandemic, the whole environment around us had been deemed very toxic to breathe in due to the amount of greenhouse gases that had been emitted over the centuries. The Earth faced rising temperatures, which in turn led to the melting of glaciers and rising of sea levels. Environmental degradation was happening fast due to the depletion of resources such as air, water and soil. But after the coronavirus lockdown (Talabandi) commenced, there have been changes in the environment. The lockdown still has a huge impact on people in India too. The halt of industrial production and traffic resulted in cleaner air and rivers. In India the first phase of the nationwide lockdown that began on March 24 followed by enforcement of a series of regulations had some evidences that the COVID-19 curve is flattening in the country's COVID-19 affected regions. There was a good chance Prime Minister Narendra Modi extended the lockdown (Talabandi) four times that ended on (Phase 1 (24 March-14 April)., Phase 2 (15 April-3 May)., Phase 3 (4 May-17 May) & Phase 4 (18 May-31 May). The paper focuses on different aspects of environmental impact due to SARS-CoV-2 in India.

Preparation and characterization and biodistribution studies of lomustine loaded plga nanoparticles by interfacial deposition method

The incorporation of lomustine, a hydrophobic anticancer drug into PLGA nanoparticles by interfacial deposition method was optimized. Based on the optimal parameters, it was found that lomustine-PLGA nanoparticles with acceptable properties could be obtained. Optimization of formulation variables to control the size and drug entrapment efficiency of the prepared nanoparticles seems to be based on the same scientific principles as drug-loaded nanoparticles prepared by nanoprecipitation, solvent evaporation method. The process was the most important factor to control the particle size, while both the drug-polymer interaction and the partition of drug in organic and aqueous phases were the crucial factors to govern the drug entrapment efficiency. PLGA concentration at lower level (100 mg), 1:5 organic phase: aqueous ratio, 1%w/v PVA concentration, 3%w/v pluronic F68 achieved smaller particle size. Additionally, L:G ratio of PLGA 75:25, lower volume of organic solvent (1:10 organic phase: aqueous phase), higher initial drug content (10 mg) enhanced the drug entrapment efficiency and maintained lomustine concentration in blood for an extended time period, elevated lomustine concentration in lungs and slowed the elimination of lomustine. The biodistribution profiles of prepared nanoparticles in albino mice showed higher plasma drug concentration for longer period of time, elevated drug concentration in lungs and slow elimination from kidney. No toxic effects of prepared nanoparticles were observed in histopathological examination of lungs and kidney. The systematic investigation reported here promises the development of PLGA nanoparticles loaded with lomustine when tested in Lung Cancer cell line L132 and toxicological/ histopathological studies in albino mice.

Ru-dye grafted cus and reduced graphene oxide (cus/rgo)composite:an efficient and photo tunable electrode for dye sensitized solar cells

The CuS@reduced graphene oxide (CuS/RGO) hybrid nanocomposite was synthesized by facile hydrothermal method and used as a photoelectrode material in photovoltaic applications. In the hydrothermal route, RGO is formed by the reduction of GO with simultaneous formation of CuS/RGO nanocomposites. The CuS/RGO nanocomposites was investigated using powder XRD, TEM, HR-TEM, Raman, XPS, DRS UV–Vis spectroscopy, Photoluminescence (PL) measurements. XRD and TEM results suggest that CuS crystalline with individual spherical like homogeneous nanoparticles sizes in the range of 45–35 nm, which is distributed throughout the RGO sheets. We further construct the flexible photoelectrodes by using CuS and RGO and studied the photovoltaic performance. Photovoltaic parameters, such as short-circuit photocurrent density, open circuit voltage, fill factor and conversion efficiency were found to be 16 mA/cm2 , 0.71 V, 70.1% and 7.81% respectively, for CuS/RGO photoelectrode. The improved photo conversion efficiency of CuS/RGO is due to enhancing the electronic injection ability and reducing the photogenerated charge recombination. These photovoltaic results indicate a simple methodology for the low cost and effortless synthesis of an alternative CuS/RGO photoelectrode in high performance photovoltaic devices.
