    Abstract Different pesticide chemicals are used to enhance crop yield by protecting from pests. Organophosphate (OPs) and Pyrethroid (PYR) are used in fields of Sanghar, Sindh Pakistan. PON1 an antioxidant enzyme implicated in OPs detoxification may predispose by OPs chronic exposure. This study was conducted to evaluate the toxic potential of active pesticide chemicals at cellular and genetic levels. To examine toxic potential, locally consumed pesticide n = 2 and reference pesticide compounds organophosphate (OPs): Chloropyrifos, Malathion and Pyrethroid (PYR): Cyprmethrin, Cyhalothrin n = 4 were tested against NIH 3T3 cells using MTS assay. Local consumer pesticides demonstrated relevance for half-maximum inhibitory concentration (IC50) 0.00035 mg/mL with selected compound. Malathion IC50 exhibited the highest cytotoxicity among four compounds at 0.0005 mg/mL. On genotoxicity analysis in exposed subjects n = 100 genotypes and alleles n = 200 exhibited significant differences in genotypic and allelic frequencies of pesticide exposed subjects and controls n = 150 (X

    Abstract Introduction: The antibiotic resistance has become a major threat to global health. The combinatorial use of two or more compounds to develop a new formulation may overcome the emerging cases of drug resistance. Moringa oleifera has been utilized as a strong nutritional, immunomodulator and therapeutic agent for decades. In this study, different parts of Moringa oleifera were screened for bioactive compounds that can act as a resistance modifying agent for multi-drug resistant organisms (MDROs).
    Methodology: Initially, the combined effect of stem bark extracts and ampicillin was calculated by checkerboard assay. Active compounds of effective extract were assessed by High Performance Liquid Chromatography (HPLC). Minimal Inhibitory Concentration (MIC) and Fractional Inhibitory Concentration Index (FICI) were calculated to evaluate the synergistic behavior of stem bark extract with ampicillin. To study the blocking of resistance pathways of Methicillin-Resistant Staphylococcus aureus (MRSA) western blot was performed.
    Results: The results revealed that stem bark has significant anti-MRSA activity. The methanolic extract of stem bark in combination with ampicillin showed the highest synergistic effect (FICI value ≤ 0.237) against MRSA. Killing kinetics and membrane potential of ampicillin alone and in combination revealed an increase in the inhibitory potential of ampicillin against MRSA. Decolourization in iodometric assay confirmed the inhibition of β-lactamase, western blot results confirmed the blocking of penicillin-binding protein (PBP2a) expression with the restoration of MRSA sensitivity against β-lactams.
    Conclusion: It can be concluded that methanolic extract of Moringa oleifera stem bark has bioactive compounds and can be used as an adjuvant with antibiotics to modify the resistance of MDROs.

    Abstract In the proposed work, a highly sensitive reduced graphene oxide (rGO) coated etched fiber Bragg grating (eFBG) pH sensor is developed and characterized. To create the sensing probe, a nanocomposite layer of rGO is coated over the unclad area of the eFBG. The analysis of rGO material has been done using different characterization tools such as UV-VIS-NIR spectroscopy, x-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM). Experiments are performed using pH samples ranging from pH 2 to pH 12 to validate the operational sensing range of the proposed sensor. The effectiveness of the proposed sensor is evaluated with various pH values by monitoring the shift in the resonance peak of the sensor's reflection spectrum in a real-time interrogation system. The sensor performs well in both low and high pH ranges, with a maximum sensitivity of 0.232 nm/pH at pH 12. Due to a shift in the rGO's optical band-gap at both low and high pH values in the samples, the sensor can detect minimal changes in concentration. In the reflected spectrum, the Bragg wavelength (

    Abstract Objective: This study aimed to evaluate the potential of ChatGPT to help students for their assess ments via MCQ at different level of cognition by using different subjects of Internal medicine. Methods: This cross-sectional study was conducted in the Department of Internal Medicine in col laboration with post graduate medical education department from June 2023 to August 2023. An MCQ bank was established from three books of MCQ’s on subject of Internal Medicine. Total 1428 MCQ’s were followed for scrutiny and 307 MCQ’s were selected for the assigned task. The selected MCQ’s were manually entered one by one in a fresh Chat GPT session. The response was noted against the replies given in respective MCQ’s book and marked as correct, not correct or partially correct. MCQ’s were categorized as per chapters in Internal medicine and as per cognition level of MCQ’s i.e. C1, C2 and C3. Data was analyzed on SPSS version 21.00. Results: Chat GPT replied with 199 correct replies while 98 were wrong and 10 were partially correct. Chat GPT scored 64% overall in all categories. At level of cognition, it solved C2 MCQ’s by 80 % but scored 69% and 54% in C1 and C3 categories respectively. Chat GPT replied with 80% accuracy for C2 level MCQ’s while results were low for C3 category at around 54%. C1 also had low percentage of correct answers standing close to 69.8%. Almost all subjects showed healthy responses around the mean except for endocrinology and hematology where responses are below 60% and 40% respectively. Conclusion: This study findings suggest that ChatGPT is a useful tool for students and medical educationist with its current framework but a subtle approach should be inclined towards its role in future.

    Abstract Abstract Different pesticide chemicals are used to enhance crop yield by protecting from pests. Organophosphate (OPs) and Pyrethroid (PYR) are used in fields of Sanghar, Sindh Pakistan. PON1 an antioxidant enzyme implicated in OPs detoxification may predispose by OPs chronic exposure. This study was conducted to evaluate the toxic potential of active pesticide chemicals at cellular and genetic levels. To examine toxic potential, locally consumed pesticide n = 2 and reference pesticide compounds organophosphate (OPs): Chloropyrifos, Malathion and Pyrethroid (PYR): Cyprmethrin, Cyhalothrin n = 4 were tested against NIH 3T3 cells using MTS assay. Local consumer pesticides demonstrated relevance for half-maximum inhibitory concentration (IC50) 0.00035 mg/mL with selected compound. Malathion IC50 exhibited the highest cytotoxicity among four compounds at 0.0005 mg/mL. On genotoxicity analysis in exposed subjects n = 100 genotypes and alleles n = 200 exhibited significant differences in genotypic and allelic frequencies of pesticide exposed subjects and controls n = 150 (X2 = 22.9, p = 0.001). Screening of genotypes were performed by PCR- RFLP. Statistical assessment carried out using online software and tools. Results suggested that higher heterozygous genotype A/G (74%) may confer low PON1 metabolic activity towards pesticides in exposed subjects. Findings could be helpful to establish health plans by avoiding toxic chemicals that harming exposed population.
