Biomedical properties, characterization of seaweeds species and antimicrobial activity.

Marine organisms produce a variety of compounds with pharmacological activities. In order to better comprehend the medicinal value of five particular seaweed orders Ulvales (Ulva intestinalis), Bryopsidales (Codium decorticatum), Ectocarpales (Iyengaria stellata), Dictyotales (Spatoglossum aspermum) and Gigartinales (Hypnea musciformis), a bioactive analysis including the screening of phytochemical components, antioxidant and antimicrobial activities was the aim of the investigation. The species include U. intestinalis was collected from Sandspit, while C. decorticatum, I. stellata, S. aspermum, and H. musciformis were gathered from Buleji. These species evaluated for their ability to inhibit human infectious gram positive pathogens Staphylococcus aureus, Staphylococcus epidermidis as well as gram negative bacteria Escherichia coli. Additionally vegetable pathogen Fusarium oxysporum, and fruit pathogens (Aspergillus niger and Aspergillus flavus) were evaluated to determine the zone of inhibition. Two organic solvents, ethanol and methanol, were used to prepare seaweed extract. The disc diffusion method was utilized to quantify the zone of inhibition and the DPPH method was employed to measure the antioxidant activity. The study unveiled various phyto-constituents in the tested seaweeds, with flavonoids, tannins, and proteins found in all selected species, while saponins, terpenoids, and carbohydrates were absent in I. stellata and S. aspermum. Notably, ethanolic extracts of I. stellata and S. aspermum demonstrated superior higher antioxidant activity, with increasing percentages of inhibition from 1 to 6 mg/ml. Furthermore, the findings indicated that the ethanolic extract of U. intestinalis displayed the highest resistance against F. oxysporum and A. flavous among other seaweeds. Meanwhile, the ethanolic extract of C. decorticatum exhibited the highest resistance against A. Niger. Additionally, the ethanolic extract of I. stellata and H. musciformis displayed the highest resistance against the gram-negative bacteria E. coli and the gram-positive bacteria S. epidermidis, whereas the methanolic extract of U. intestinalis demonstrated the highest resistance against the gram-positive bacteria S. aureus. The findings of this investigation show that a range of bioactive compounds with antioxidant properties are involved in the antimicrobial activities of disease-causing pathogens.

Unveiling diagnostic prowess: a comparative study of exercise treadmill test and CT coronary in coronary artery disease detection in Pakistan (2021-2023).

Coronary Artery Disease (CAD) is a global health concern, with diagnostic modalities and risk factors that exhibit regional variations. This study, conducted at the Islamabad Diagnostic Center, Pakistan, aimed to provide a comprehensive assessment of CAD prevalence, severity, and associated risk factors, while also evaluating the diagnostic accuracy of Computed Tomography Coronary Test (CTT) and Exercise Treadmill Test (ETT) in a cohort of 2909 patients. Among the patients assessed via CT Coronary scans, CAD was universally observed, presenting with varying degrees of severity. Our findings indicated that 24.5% of patients had mild CAD, 28.6% exhibited mild to moderate CAD, 16.3% were diagnosed with moderate CAD, 18.4% demonstrated moderate to severe CAD, and 20.4% displayed severe CAD. This spectrum underscores the diverse nature of CAD within the study population. In addition to CTT, we conducted a detailed evaluation of ETT results in 49 patients. These results revealed that 55.1% of patients tested positive for ischemia during the exercise test, emphasizing the prevalence of cardiac stress and underlying CAD. Conversely, 32.7% of patients exhibited negative ETT results, indicating favorable cardiac tolerance during physical activity. A subset of patients yielded non-diagnostic or inconclusive results, necessitating further clinical assessment. Disease history analysis showed a dichotomy within the cohort, with 20.4% having a known medical history and 79.6% possessing an unknown disease history, highlighting the importance of comprehensive medical records in clinical practice. Hypertension, a critical cardiovascular risk factor, was identified in 87.8% of patients, underscoring its significance. Smoking history displayed notable variation, with 69.4% categorized as smokers, 14.3% as ex-smokers, and 10.2% as non-smokers. Lipid profile analysis indicated that 69.4% of patients had abnormal lipid levels. To assess the diagnostic accuracy of CTT and ETT, we calculated Positive Predictive Values (PPV) and Negative Predictive Values (NPV). CTT exhibited a PPV of approximately 5.99% and an NPV of approximately 4.40%, whereas ETT displayed a higher PPV of around 26.44% and a substantially higher NPV of about 49.24%. This study offers valuable insights into CAD prevalence, severity, and associated risk factors in a Pakistani cohort, emphasizing the importance of holistic risk assessment and tailored interventions in clinical practice. Our findings also highlight the diagnostic utility of ETT in CAD assessment.

SARS-CoV-2 clearance in term of Cycle Threshold (Ct) during first two waves of COVID-19 in Pakistan: a phenomenon of delayed viral clearance post-corticosteroid treatment.

SARS-CoV-2 is recently emerged virus, which caused millions of deaths, all over the world. To tackle COVID-19 pandemic, there is an utmost need for in-depth analysis of viral replication. We aimed to examine viral load in SARS-CoV-2 patients during first two waves of COVID-19 in Pakistan. 225,615 suspected subjects from 75 different regions of Pakistan were selected in the study. SARS-CoV-2 RNAs were detected via real time PCR. During first wave (period of June-July, 2020) of COVID-19 the prevalence of SARS-CoV-2 was 20.38%. However, during second wave (period of November-December, 2020) of COVID-19, the rate of prevalence was 9.41%. During first wave of COVID-19 96.31% of participants remained PCR positive for 14 to 21 days, 3.39% of subjects showed positive results for 22 to 35 days, while delayed Ct values were observed among 0.26% of participants for 36 to 49 days. However, during second wave of COVID-19 89.31% of the subjects exhibited symptoms and showed real-time PCR positive results for 14 to 21 days, 9.42% showed positive results for 22 to 35 days, while significantly delayed Ct value results were observed among 1.026% of participants for 36 to 63 days (3.95 times higher than first wave). In contrast to first wave of COVID-19, the factors that were different in second wave were neither viral (different strains) nor host (same population). But treatment factors changed significantly. As during second wave besides azithromycin, corticosteroid dexamethasone consumption was increased consequently causing delayed Ct value negativity. This suggests that corticosteroid treatment might be linked with delayed Ct value or viral clearance. This study is crucial for re-considering effective therapeutic options against COVID-19.

Analytical assessment of clinical sensitivity and specificities of pharmaceutical rapid SARS-CoV-2 detection nasopharyngeal swab testing kits in Pakistan.

Despite of the global unity against COVID-19 pandemic, the threat of SARS-CoV-2 variants on the lives of human being is still not over. SARS-CoV-2 pandemic has urged the need of rapid viral detection at earliest. To cope with gradually expanding scenario of SARS-CoV-2, accurate diagnosis is extremely crucial factor which should be noticed by international health organizations. Limited research followed by sporadic marketing of SARS-CoV-2 rapid pharmaceutical detection kits raises critical questions against quality assurance and quality control measures. Herein we aimed to interrogate effectivity and specificity analysis of SARS-CoV-2 pharmaceutical rapid detection kits (nasopharyngeal swab based) using conventional gold standard triple target real-time polymerase chain reaction (USFDA approved). A cross-sectional study was conducted over 1500 suspected SARS-CoV-2 patients. 100 real time-PCR confirmed patients were evaluated for pharmaceutical RDT kits based upon nasopharyngeal swab based kits. The SARS-CoV-2 nasopharyngeal swab based rapid diagnostic kit (NSP RDTs) analysis showed 78% reactivity. Among real time PCR confirmed negative subjects, 49.3% represented false positivity. The positive predictive analysis revealed 67.82%, while negative predictive values were 64.40%. The NSP RDTs showed limited sensitivities and specificities as compared to gold standard real time PCR. Valid and authentic detection of SARS-CoV-2 is deemed necessary for accurate COVID-19 surveillance across the globe. Current study highlights the potential consequences of inadequate detection of SARS-CoV-2 and emerging novel mutants, compromising vaccine preventable diseases. Current study emphasizes need to wake higher authorities including strategic organizations for designing adequate measures to prevent future SARS-CoV-2 epidemics.

Dietary habits of lesser bandicoot rat (Bandicota Bengalensis) in an agro-ecosystem, Pothwar Plateau, Pakistan

Abstract Dietary habits of bandicoot rats (bandicota bengalensis) were investigated in the agricultural crops of the Pothwar Plateau, Pakistan by analysing stomach contents. The research activities were conducted in major field crops including wheat-groundnut and in the fallow lands during non-crop season at the field boundaries. The specimens were captured from the fields using kill/snap traps, and dissected to collect their stomach samples for laboratory analysis. Light microscopic slides of the plant material were recovered from stomach samples and the reference materials were collected from the field. Results revealed that the bandicoot rat predominantly fed upon cultivated crops during cropping season but consumed wild vegetation during non-cropping season. There was no significance difference between summer and winter diets. Most frequently consumed crop food items were wheat (Triticum aestivum; 28.57%), groundnut (Arachis hypogea; 11.26%), sorghum (Sorghum bicolor; 10.17%), chickpea (Cicer arietinum; 9.52%), maize (Zea mays; 6.49%), millet (Pennisetum glaucum; 5.84%), barley (Hordeum vulgare; 4.98%) and mustard (Brassica campestris; 4.98%). Among wild vegetation were consumed khbal gha (Cynodon dactylon; 7.79%), baron dhab (Demostachya bipinnata; 7.36%) and Prickly flower (Achyranthes aspera; 3.03%). The study concludes that, in addition to consuming wheat and groundnut crops, the Lesser bandicoot rat also subsists on grasses, weeds, and some fodder crops, as important component of its diet in agro-ecosystem of the Pothwar Plateau.

Resumo Os hábitos alimentares de ratos bandicoot (Bandicota bengalensis) foram investigados nas plantações agrícolas do planalto de Pothwar, Paquistão, por meio da análise do conteúdo estomacal. As atividades da pesquisa foram conduzidas nas principais culturas de campo, incluindo trigo e amendoim, e em terras de pousio durante a estação não agrícola nos limites do campo. Os espécimes foram capturados dos campos usando armadilhas kill/snap e dissecados para coletar suas amostras de estômago para análise laboratorial. Lâminas de microscopia de luz do material vegetal foram recuperadas de amostras de estômago; os materiais de referência foram coletados no campo. Os resultados revelaram que o rato bandicoot alimentava-se predominantemente de culturas cultivadas durante a época de cultivo, mas consumia vegetação selvagem durante a época de não colheita. Não houve diferença significativa entre as dietas de verão e inverno. Os alimentos agrícolas mais frequentemente consumidos foram trigo (Triticum aestivum; 28,57%), amendoim (Arachis hypogea; 11,26%), sorgo (Sorghum bicolor; 10,17%), grão de bico (Cicer arietinum; 9,52%), milho (Zea mays; 6,49%), milheto (Pennisetum glaucum; 5,84%), cevada (Hordeum vulgare; 4,98%) e mostarda (Brassica campestris; 4,98%). Entre a vegetação silvestre foram consumidos khbal gha (Cynodon dactylon; 7,79%), barão dhab (Demostachya bipinnata; 7,36%) e flor espinhosa (Achyranthes aspera; 3,03%). O estudo conclui que, além de consumir culturas de trigo e amendoim, o rato bandicoot pequeno também subsiste de gramíneas, ervas daninhas e algumas culturas forrageiras, componentes importantes de sua dieta no agroecossistema do planalto de Pothwar.

Drinking water quality of various sources in Peshawar, Mardan, Kohat and Swat districts of Khyber Pakhtunkhwa province, Pakistan

Abstract The present study involves the chemical and bacteriological analysis of water from different sources i.e., bore, wells, bottle, and tap, from Peshawar, Mardan, Swat and Kohat districts of Khyber Pakhtunkhwa (KP) province, Pakistan. From each district, 50 water samples (10 samples from each source), regardless of urban and rural status, were collected from these sources and analysed for sulphates, nitrates, nitrites, chlorides, total soluble solids and coliforms (E. coli). Results indicated that majority of the water sources had unacceptable E. coli count i.e.> 34 CFU/100mL. E. coli positive samples were high in Mardan District, followed by Kohat, Swat and Peshawar district. Besides this, the some water sources were also chemically contaminated by different inorganic fertilizers (nitrates/nitrites of sodium, potassium) but under safe levels whereas agricultural and industrial wastes (chloride and sulphate compounds) were in unsafe range. Among all districts, the water quality was found comparatively more deteriorated in Kohat and Mardan districts than Peshawar and Swat districts. Such chemically and bacteriologically unfit water sources for drinking and can cause human health problems.

Resumo O presente estudo envolve a análise química e bacteriológica de água de diferentes fontes, ou seja, furo, poços, garrafa e torneira, dos distritos de Peshawar, Mardan, Swat e Kohat da província de Khyber Pakhtunkhwa (KP), Paquistão. De cada distrito, 50 amostras de água (10 amostras de cada fonte), independentemente do status urbano e rural, foram coletadas dessas fontes e analisadas para sulfatos, nitratos, nitritos, cloretos, sólidos solúveis totais e coliformes (E. coli). Os resultados indicaram que a maioria das fontes de água tinha uma contagem inaceitável de E. coli, ou seja, > 34 UFC / 100 mL. As amostras positivas para E. coli foram elevadas no distrito de Mardan, seguido por Kohat, Swat e distrito de Peshawar. Além disso, algumas fontes de água também foram contaminadas quimicamente por diferentes fertilizantes inorgânicos (nitratos/nitritos de sódio, potássio), mas em níveis seguros, enquanto os resíduos agrícolas e industriais (compostos de cloreto e sulfato) estavam em níveis inseguros. Entre todos os distritos, a qualidade da água foi considerada comparativamente mais deteriorada nos distritos de Kohat e Mardan do que nos distritos de Peshawar e Swat. Essas fontes de água química e bacteriologicamente impróprias para beber podem causar problemas à saúde humana.

Therapeutic potential of stem cell and melatonin on the reduction of CCl4-induced liver fibrosis in experimental mice model

Abstract Liver fibrosis is initial stage of any chronic liver disease and its end stage is develops into cirrhosis. Chronic liver diseases are a crucial global health issue and the cause of approximately 2 million deaths per year worldwide. Cirrhosis is currently the 11th most common cause of death globally. Mesenchymal stem cell (MSCs) treatment is the best way to treat acute and chronic liver disease. The aim of this study is to improve the therapeutic potential of MSCs combined with melatonin (MLT) to overcome CCl4-induced liver fibrosis and also investigate the individual impact of melatonin and MSCs against CCl4-induced liver impairment in animal model. Female BALB/c mice were used as CCL4-induced liver fibrotic animal model. Five groups of animal model were made; negative control, Positive control, CCl4+MSCs treated group, CCl4+MLT treated group and CCl4+MSCs+MLT treated group. Cultured MSCs from mice bone marrow were transplanted to CCl4-induced liver injured mice model, individually as well as together with melatonin. Two weeks after MSCs and MLT administration, all groups of mice were sacrificed for examination. Morphological and Histopathological results showed that combined therapy of MSCs+MLT showed substantial beneficial impact on CCl4-induced liver injured model, compared with MSCs and MLT individually. Biochemically, considerable reduction was observed in serum bilirubin and ALT levels of MLT+MSC treated mice, compared to other groups. PCR results shown down-regulation of Bax and up-regulation of Bcl-xl and Albumin, confirm a significant therapeutic effect of MSCs+MLT on CCI4-induced liver fibrosis. From the results, it is concluded that combined therapy of MSCs and MLT show strong therapeutic effect on CCL4-induced liver fibrosis, compared with MSCs and MLT individually.

Cinco grupos de modelo animal foram feitos: Controle Negativo, Controle Positivo, CCl4 + MSCs Tratados Grupo, Grupo Tratado CCl4 + MLT e Grupo Tratado CCl4 + MSCs + MLT. MSCs cultivados da medula óssea dos ratos foram transplantados para o modelo de camundongos de fígado induzido por CCl4, individualmente, bem como em conjunto com a melatonina. Duas semanas após a administração MSCs e MLT, todos os grupos de camundongos foram sacrificados para o exame. Os resultados morfológicos e histopatológicos mostraram que a terapia combinada do MSCs + MLT mostrou impacto benéfico substancial no modelo ferido no fígado induzido pelo CCl4, em comparação com o MSCs e o MLT individualmente. A redução bioquimicamente considerável foi observada em bilirrubina sérica e níveis ALT de ratinhos tratados com MLT + MSCs, em comparação com outros grupos. Os resultados de PCR mostraram regulação negativa do BAX e regulação positiva do BCL-XL e da albumina, confirmando um efeito terapêutico significativo do MSCs + MLT na fibrose hepática induzida por CCl4. Dos resultados, conclui-se que a terapia combinada de MSCs e MLT mostram um forte efeito terapêutico na fibrose hepática induzida por CCl4, em comparação com MSCs e MLT individualmente.

Genomic characterization of Puccinia triticina using molecular marker technology / Caracterização genômica de Puccinia triticina usando tecnologia de marcadores moleculares

Leaf rust, caused by Puccinia triticina, is the most common rust disease of wheat. The fungus is an obligate parasite capable of producing infectious urediniospores. To study the genetic structure of the leaf rust population 20 RAPD primers were evaluated on 15 isolates samples collected in Pakistan. A total of 105 RAPD fragments were amplified with an average of 7 fragments per primer. The number of amplified fragments varied from 1 to 12. GL Decamer L-07 and GL Decamer L-01 amplified the highest number of bands (twelve) and primer GL Decamer A-03 amplified the lowest number of bands i.e one. Results showed that almost all investigated isolates were genetically different that confirms high genetic diversity within the leaf rust population. Rust spores can follow the migration pattern in short and long distances to neighbor areas. Results indicated that the greatest variability was revealed by 74.9% of genetic differentiation within leaf rust populations. These results suggested that each population was not completely identical and high gene flow has occurred among the leaf rust population of different areas. The highest differentiation and genetic distance among the Pakistani leaf rust populations were detected between the leaf rust population in NARC isolate (NARC-4) and AARI-11and the highest similarity was observed between NARC isolates (NARC-4) and (NARC-5). The present study showed the leaf rust population in Pakistan is highly dynamic and variable.

A ferrugem da folha, causada por Puccinia triticina, é a ferrugem mais comum do trigo. O fungo é um parasita obrigatório, capaz de produzir urediniósporos infecciosos. Para estudar a estrutura genética da população de ferrugem da folha, 20 primers RAPD foram avaliados em 15 amostras de isolados coletadas no Paquistão. Um total de 105 fragmentos RAPD foram amplificados com uma média de 7 fragmentos por primer. O número de fragmentos amplificados variou de 1 a 12. GL Decamer L-07 e GL Decamer L-01 amplificaram o maior número de bandas (doze), e o primer GL Decamer A-03 amplificou o menor número de bandas, ou seja, um. Os resultados mostraram que quase todos os isolados investigados eram geneticamente diferentes, o que confirma a alta diversidade genética na população de ferrugem da folha. Os esporos de ferrugem podem seguir o padrão de migração em distâncias curtas e longas para áreas vizinhas. Os resultados indicaram que a maior variabilidade foi revelada por 74,9% da diferenciação genética nas populações de ferrugem. Esses resultados sugeriram que cada população não era completamente idêntica e um alto fluxo gênico ocorreu entre a população de ferrugem da folha de diferentes áreas. A maior diferenciação e distância genética entre as populações de ferrugem da folha do Paquistão foram detectadas entre a população de ferrugem da folha no isolado NARC (NARC-4) e AARI-11 e a maior similaridade foi observada entre os isolados NARC (NARC-4) e (NARC-5). O presente estudo mostrou que a população de ferrugem da folha no Paquistão é altamente dinâmica e variável.

Drought stress enhances the efficiency of floral dip method of Agrobacterium-mediated transformation in Arabidopsis thaliana / Estresse hídrico aumenta a eficiência do método de imersão floral de transformação mediado por Agrobacterium em Arabidopsis thaliana

The Agrobacterium-mediated floral dip protocol is the most extensively used transformation method for a model plant Arabidopsis thaliana. Several useful methods for Agrobacterium tumefaciens-mediated transformations of Arabidopsis are existing, but they are time consuming and with low transformation efficiency. Here, we developed a transgenic Arabidopsis lines TET12p::TET12-RFP in a short period of time and enhanced transformation efficiency by using a modified transformation method by applying drought stress after floral dip. In this protocol, Agrobacterium cells carrying TET12p::TET12-RFP recombinant vectors were resuspended in a solution of 5% sucrose, 0.05% (v/v) silwet L-77 to transform female gametes of developing Arabidopsis inflorescences. Treated Arabidopsis were then applied with different levels of drought stresses to stimulate plants for the utilization of maximum plant energy in seed maturation process. The applied stresses achieved the fast maturation of already treated inflorescences while stopped the growing of newly arising untreated inflorescence, thus decreased the chances of wrong collection of untransformed seeds. Consequently, the collected seeds were mostly transgenic with a transformation frequency of at least 10%, thus the screening for positive transformants selection was more advantageous on a selective medium as compared to a classical floral dip method. Within 2-3 months, two hundred of individual transgenic plants were produced from just 10 infiltrated plants. This study concludes that application of drought stresses in a specific stage of plant is a beneficial strategy for achieving the transgenic Arabidopsis in a short period of time with high transformation efficiency.

O protocolo de imersão floral mediado por Agrobacterium é o método de transformação mais amplamente utilizado para uma planta-modelo Arabidopsis thaliana. Existem vários métodos úteis para transformações de Arabidopsis mediados por Agrobacterium tumefaciens, mas são demorados e com baixa eficiência de transformação. Aqui, desenvolvemos uma linha transgênica de Arabidopsis TET12p::TET12-RFP em um curto período de tempo e eficiência de transformação aprimorada usando um método de transformação modificado por meio da aplicação de estresse hídrico após o mergulho floral. Neste protocolo, células de Agrobacterium transportando vetores recombinantes TET12p::TET12-RFP foram ressuspensas em uma solução de 5% de sacarose, 0,05% (v/v) silwet L-77 para transformar gametas femininos de inflorescências de Arabidopsis em desenvolvimento. Arabidopsis tratadas foram então aplicadas com diferentes níveis de estresse hídrico para estimular as plantas a utilizar o máximo de energia da planta no processo de maturação das sementes. Os estresses aplicados alcançaram a rápida maturação das inflorescências já tratadas enquanto paravam o crescimento de inflorescências não tratadas recém-surgidas, diminuindo, assim, as chances de coleta errada de sementes não transformadas. Consequentemente, as sementes coletadas eram principalmente transgênicas, com uma frequência de transformação de pelo menos 10%; portanto, a triagem para seleção dos transformantes positivos foi mais vantajosa em um meio seletivo em comparação com um método clássico de imersão floral. Dentro de 2-3 meses, 200 plantas transgênicas individuais foram produzidas a partir de apenas 10 plantas infiltradas. Este estudo conclui que a aplicação de estresse hídrico em um estágio específico da planta é uma estratégia benéfica para alcançar a Arabidopsis transgênica em um curto período de tempo com alta eficiência de transformação.

Antidiabetic and hepato-renal protective effects of medicinal plants in STZ induced diabetic rats / Efeitos antidiabéticos e hepatorrenais de plantas medicinais em ratos diabéticos induzidos por STZ

The antidiabetic and hepato-renal protective effects of Citrullus colocynthis and Momordica charantia ethanol extracts were investigated in streptozotocin (STZ) induced diabetic male albino rats. Diabetic rats were treated with C. colocynthis, M. charantia or C. colocynthis + M. charantia mixed extract at a dose of 250 mg /kg body weight per oral per day for 21 days. The mean body weight of all the diabetic rat groups on day 1 of treatment (day 10 of diabetes) was significantly lower than the normal control rat group (P<0.05). The blood glucose level of all the diabetic rat groups on day 1 of treatment (day 10 of diabetes) was significantly (P<0.05) higher (> 200 mg/dl) than the normal control rat group (95.5 ± 2.7). At the end of treatment (day 21), the diabetic rats treated with plant extracts showed significant increase (P<0.05) in body weight and significant (P<0.05) reduction in blood glucose level when compared to diabetic control animals. Significant increase (< 0.05) was observed in the serum bilirubin, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), urea and creatinine levels of diabetic control rat group. The serum levels of these liver and kidney-related parameters of diabetic rats treated with plant extract were significantly lower when compared to diabetic control rat group (p < 0.05). Photomicrographs of liver and kidney microsections from diabetic rats treated with these plant extracts showed amelioration in the hepato-renal histoarchitectures. It was concluded that the C. colocynthis and M. charantia methanol extracts are antidiabetic and hepato-renal protective in STZ induced diabetic male rats. Treatment of the diabetic rats with C. colocynthis + M. charantia mixed extract is more effective in the amelioration of diabetes and hepato-renal injuries in STZ induced diabetic male rats.

Os efeitos protetores antidiabéticos e hepatorrenais dos extratos etanólicos de Citrullus colocynthis e Momordica charantia foram investigados em ratos albinos machos diabéticos induzidos por estreptozotocina (STZ). Ratos diabéticos foram tratados com extrato misto de C. colocynthis, M. charantia ou C. colocynthis + M. charantia na dose de 250 mg/kg de peso corporal por via oral por dia durante 21 dias. O peso corporal médio de todos os grupos de ratos diabéticos no dia 1 de tratamento (dia 10 de diabetes) foi significativamente menor do que o grupo de ratos controle normal (P < 0,05). O nível de glicose no sangue de todos os grupos de ratos diabéticos no dia 1 de tratamento (dia 10 de diabetes) foi significativamente (P < 0,05) maior (> 200 mg/dl) do que o grupo de ratos controle normal (95,5 ± 2,7). Ao final do tratamento (dia 21), os ratos diabéticos tratados com extratos vegetais apresentaram aumento significativo (P < 0,05) no peso corporal e redução significativa (P < 0,05) na glicemia quando comparados aos animais controle diabéticos. Aumento significativo (< 0,05) foi observado nos níveis séricos de bilirrubina, alanina transaminase (ALT), aspartato transaminase (AST), fosfatase alcalina (ALP), ureia e creatinina do grupo controle diabético. Os níveis séricos desses parâmetros hepáticos e renais de ratos diabéticos tratados com extrato vegetal foram significativamente menores quando comparados ao grupo controle de ratos diabéticos (p < 0,05). Fotomicrografias de microseções de fígado e rim de ratos diabéticos tratados com esses extratos vegetais mostraram melhora nas histoarquiteturas hepatorrenais. Concluiu-se que os extratos metanólicos de C. colocynthis e M. charantia são antidiabéticos e hepatorrenais protetores em ratos machos diabéticos induzidos por STZ. O tratamento de ratos diabéticos com extrato misto de C. colocynthis + M. charantia é mais eficaz na melhora do diabetes e lesões hepatorrenais em ratos machos diabéticos induzidos por STZ.

Association of genetic polymorphism of glutathione S-transferases with colorectal cancer susceptibility in snuff (Naswar) addicts / Associação de polimorfismo genético de glutationa S-transferase com suscetibilidade ao câncer colorretal em viciados em rapé (Naswar)

The current study aimed to investigate the relationship between polymorphisms in detoxifying (GSTM1, GSTT1, and GSTP1) genes and their association with colorectal cancer (CRC) in tobacco addicts of Pashtun ethnicity. Polymorphisms in the selected genes were genotyped in a case-control study consisting of 100 histologically confirmed male CRC patients and 100 birth-year and gender-matched healthy controls using the PCR−RFLP method. The GSTM1 null, and GSTT1 null genotypes were significantly contributed to the risk of CRC in the cases (OR= 3.131, 95% CI: 1.451−6.758, P = 0.004, and OR= 3.541, 95% CI: 1.716−7.306, P = 0.001, respectively), whereas the association observed for GSTP1 Val/Val (1.139, 95% CI: 0.356−3.644, P = 0.826) did not show statistical significance. The combined GSTM1 null and GSTT1 null showed a 41-fold increased risk (95% CI: 4.945−351.950, P = 0.001), while, the combined GSTM1 null and GSTP1 Ile/Val or Val/Val variant genotypes exhibited about 3-fold (95% CI: 1.196−7.414, P = 0.019) increased risk to CRC. Similarly, the combined GSTT1 null and GSTP1 Ile/Val or Val/Val variant genotypes showed about a 3-fold (95% CI: 1.285−8.101, P = 0.013) increased risk of CRC. In the combination of three GST genotypes, the GSTM1 null, GSTT1 null, and GSTP1 Ile/Val or Val/Val variant genotypes demonstrated a more than a 22-fold (95% CI: 2.441−212.106, P = 0.006) increased risk of CRC. Our findings suggest that GSTM1 and GSTT1 polymorphism and its combination with GSTP1 may be associated with CRC susceptibility in the Naswar addicted Pashtun population of Khyber Pakhtunkhwa, Pakistan.

O presente estudo teve como objetivo investigar a relação entre polimorfismos em genes desintoxicantes (GSTM1, GSTT1 e GSTP1) e sua associação com câncer colorretal (CCR) em tabagistas da etnia pashtun. Os polimorfismos nos genes selecionados foram genotipados em um estudo de caso-controle composto por 100 pacientes do sexo masculino com CCR, confirmados histologicamente, e 100 controles saudáveis, ​​pareados por ano de nascimento e sexo usando o método PCR-RFLP. Os genótipos GSTM1 nulo e GSTT1 nulo contribuíram significativamente para o risco de CCR nos casos (OR = 3,131, IC 95%: 1,451-6,758, P = 0,004; OR = 3,541, IC 95%: 1,716-7,306, P = 0,001, respectivamente), enquanto a associação observada para GSTP1 Val/Val (1,139, IC 95%: 0,356-3,644, P = 0,826) não apresentou significância estatística. O GSTM1 nulo e o GSTT1 nulo combinados mostraram um risco 41 vezes maior (IC 95%: 4,945-351,950, P = 0,001) para CCR, enquanto os genótipos GSTM1 nulo e GSTP1 Ile/Val ou Val/Val combinados apresentaram risco cerca de 3 vezes maior (IC 95%: 1,196-7,414, P = 0,019) para CCR. Da mesma forma, os genótipos combinados GSTT1 nulo e GSTP1 Ile/Val ou Val/Val tiveram um risco para CRC cerca de 3 vezes maior (95% CI: 1,285-8,101, P = 0,013). Na combinação de três genótipos GST, os genótipos GSTM1 nulo, GSTT1 nulo e GSTP1 Ile/Val ou Val/Val apresentaram um risco 22 vezes maior (IC 95%: 2,441-212,106, P = 0,006) para CRC. Nossos achados sugerem que o polimorfismo GSTM1 e GSTT1 e sua combinação com GSTP1 podem estar associados à suscetibilidade ao CRC da população pashtun de Khyber Pakhtunkhwa, Paquistão, viciada em Naswar.

Evaluation of histo-toxicity of nimesulide in Black Kites (Milvus migrans): a pharmacodynamic study.

The present experimental work was conducted to elucidate the toxicity of nimesulide at three different doses in black kites (Milvus migrans). M. migrans is one of the most common raptors near human habitations. The goal of the current investigation was to determine whether nimesulide is similarly hazardous to raptors as was diclofenac sodium and to investigate the acute oral toxicity of nimesulide in these birds. For this study, eight adult male black kites (M. migrans) were randomly divided into four groups. M. migrans in the control group (n = 02) were not treated with nimesulide. The other three groups were given nimesulide doses. The birds in the first (n = 02) were declared the control group. The second (n = 02), third (n = 02), and fourth groups were administered nimesulide at a low, medium, and high dose of 2, 4, and 6 mg/kg live body weight of bird/day, respectively, for 10 days. Nimesulide-addled birds became listless and despondent, then anorexic. The birds were standing there with their eyes closed and showing no signs of life. There was an increase in saliva production, a slowing of breathing, and dilated pupils. No clinical signs were observed in the control group. No mortality was seen in the control or treated groups. The control group did not show lesions of gout, but black kites intoxicated with nimesulide at 2, 4, and 6 mg/kg live body weight of bird/day showed inflammation, apoptosis, hemorrhage, necrosis, and leukocytic infiltration tissues of the liver, kidney, and heart of black kites (M. migrans) treated with different concentrations of nimesulide. The treated groups also showed apoptosis of myofibrils and hyperplasia. The hypertrophy, atrophy, fibrosis, necrosis of skeletal muscles and hemorrhage were prominent in the muscles of black kites (M. migrans) intoxicated with nimesulide. All observed histological alterations got worse in a dose-related way. There was no significant difference in AST, ALT, ALP, serum uric acid, but a significant difference was observed in the values of serum urea (p = 0.001) and serum creatinine (p = 0.019).
