Potencial terapéutico de las especies de Fabaceae: Una investigación fitoquímica y de bioactividad

Introduction: The increasing prevalence of chronic diseases and infectious ailments necessitates the exploration of novel therapeutic agents. This study aims to elucidate selected Fabaceae species’ phytochemical composition and biological activities. Methods: Antioxidant potential was assessed with the DPPH assay, while DNA protection and antidiabetic activity were tested via inhibition assays. Anti-leishmanial and anti-dengue potentials were evaluated against Leishmania major and Aedes aegypti. Results: Sophora mollis, Mucuna pruriens, and Sesbania sesbans exhibited the highest phytochemical content. The DPPH-scavenging power of M. pruriens was highest (14.09 ± 3.60 µg/ml), and the DNA protection ability of P. tuberosa methanol extracts was highest.   The methanol extract of S. sesbans effectively inhibited leishmaniasis (82.99 % inhibition) and dengue (70.10 ppm LD50). GC/MS identified 37 compounds, with 9-octadecenamide (Z) and tetradecanamide predominating. Conclusion: The methanol leaves extracts of selected Fabaceae species revealed significant biological properties compared to the methanol-DMSO and methanol-glycerol extracts. Furthermore, carrying out the synergistic effects of antileishmanial, anti-dengue, antidiabetic, and antioxidant compounds, may lead to the development of more effective and comprehensive therapeutic strategies.Introducción: La creciente prevalencia de enfermedades crónicas y dolencias infecciosas requiere la exploración de nuevos agentes terapéuticos.

Upgradation in Physio-Chemical Characteristics and Thermal Behaviour of Thar Coal Subjected to Torrefaction

This study explores the improvement in physiochemical attributes, thermal behavior, and combustion characteristics of low-rank Thar coal through torrefaction, a thermal pretreatment process. Thar coal samples were torrefied at five temperatures (200, 225, 250, 275, and 300°C) for two residence times (30 and 60 minutes). The study assessed changes in proximate and ultimate composition, calorific value, energy density and combustion traits of untreated and torrefied coal using thermogravimetric analysis (TGA). Results indicated slight improvement at low torrefaction temperatures (200-225°C), while higher temperatures (275-300°C) significantly enhanced fuel properties. Key findings include increased fixed carbon, reduced moisture and volatile matter, and higher heating value (HHV). The TGA graph demonstrated that torrefied coal has improved fuel properties compared to raw coal samples. The derivative thermogravimetric curve (DTG) shifted upward, signifying a change in peak (Tm) and decomposition temperatures along with an increased torrefaction temperature. The samples torrefied at 300°C for 60 minutes yielded best results, showing improved ignition (Ti) and burnout temperatures (Tb) and reduced emissions. This research focuses on torrefaction as a potential technique for improving the quality of low-grade coals of Pakistan hence opening up opportunities for controlled energy production

Assistive Technology Empowering Individuals with Disabilities

TAC is an inclusive enabler technology that helps people with disabilities to function through personal assistance technology and gears. Enablement with assistive technology (AT) improves the independence, interaction and community involvement of persons with disability. This study looks at AT to determine the uses, pros, and cons to embrace the technology. Thus, the method and framework cover a survey of 100 persons with disabilities from three setting hospitals in Pakistan namely, Pakistan institute of Medical Science (Pims), Poly Clinic Hospital and Holy Family Hospital person’s disabled preferred AT device through close ended questionnaires and interviews of thirty AT users and five industry experts. The present study finds that 82% of the participants found extended degree of independence and productivity with the use of AT, while the 76% said that there was enhanced communication and mobility. The use of progressive interfaces including artificial intelligent based communication equipment and virtually connected tools were closely associated with the management of complex disabilities. Still, issues like cost, awareness, and availability remain the main inhibitors to the broad use of the systems. However, there are some problems have been observed that include high cost, low awareness, and physical access which in one way or another hinder the adoption of the framework fully. The results show that IT should extend to the design of assistive technologies, costs should be kept as low as possible, and that public health campaigns should be concentrated on the potential of AT. This research is thus ended by calling for a multisectoral effort towards hoping that, assistive technology remains a viable and accessible tool for individuals with disability

Effects of Fertilizers on Copper and Nickel Accumulation and Human Health Risk Assessment of Vegetables and Food Crops

Despite the fact that fertilizers have been used for millennia for sustainable crop production, this high and considerable dependence on fertilizers heightens environmental concerns with the indirect human exposure due to accumulation of toxins in food chain via soil contamination. The purpose of this study is to evaluate the application of fertilizers to the soil and their effect on the accumulation of copper and nickel in spinach (Spinacia oleracea), garlic (Allium sativum), wheat (Triticum aestivum), maize (Zea mays), and barley (Hordeum vulgare); as well as potential health concerns associated with consuming vegetables cultivated on this contaminated land. Samples of available soil, food crops, and human blood were collected from three different Tehsils: Bhalwal, Sahiwal, and Silanwali and were regarded as site 1, site 2 and site 3 respectively. Urea, farmyard manure, and potassium chloride were delivered to Site 1; urea phosphate, manure, and ammonium sulphate were delivered to Site 2; and superphosphate, ammonium phosphate, and nitrate phosphate were delivered to Site 3. Data was subjected to statistical analysis for computing out ANOVA and correlation. Analysis revealed that minimum copper concentration was found in the soil of T. aestivum grown at Site-1 while the inhabitants of Site 3 had the highest concentration of Cu in their blood. The highest level of HIR was found in the human beings that ate the S. oleracea grown at Site 3. It is strongly advised that fertilizers be used sparingly, as their excessive use can cause human health risks
