Heavy metal impacts on antioxidants in cow blood from wastewater-irrigated areas.

The aim of the present research was to investigate the presence of heavy metals such as lead (Pb), copper (Cu), chromium (Cr), and cadmium (Cd) in blood samples from cows raised with irrigated wastewater, as well as in the wastewater itself, in the North-western region of Pakistan. A total of 60 blood samples were collected from five different locations in Kohat, namely Tappi Road (TR), Pindi Road (PR), Gul Malik Road (GMR), Markaz Road (MR), and a control group. The samples of both i.e. cow blood and wastewater were analyzed for the concentrations of heavy metals. The highest concentration of Cd was detected in the MR site with a mean value of 0.03 mg/L, and the highest concentration of Cu (0.04 mg/L) was recorded in the TR site, while the lowest level was found in the control group with a mean of 0.002 mg/L in blood samples. The highest Cr and Pb concentrations were found at the PR site, with mean values of 0.03 and 0.07 mg/L, respectively, whereas the control group had the lowest concentrations, with mean values of 0.002 and 0.01 mg/L. Similarly, heavy metal concentrations were analyzed in wastewater used for irrigation in the study area. Results indicated elevated concentrations of Cu and Cr in wastewater, although they remained below the World Health Organization (WHO) recommended values except for Cr (0.13 mg/L) in the GMR site, which exceeded permissible limits. Cd and Pb concentrations in wastewater were relatively low, but Cd concentration surpassed WHO limits, particularly with a mean concentration of 0.08 mg/L in the TR site. Comparison between heavy metal concentrations in blood and wastewater revealed higher values of Cd and Pb in blood samples than in wastewater, while Cu and Cr concentrations were higher in water compared to blood. Additionally, elevated levels of Super Oxide Dismutase (SOD), antioxidant enzyme Catalase (CAT), and oxidative stress marker malondialdehyde (MDA) were detected in blood samples. Cluster and principal component analyses were employed to assess heavy metal toxicity among the groups, indicating potential long-term adverse health effects on animals, transfer to humans, and toxicity in living organisms.

The HR revolution: Redefining performance paradigms in Pakistan's pharma landscape through moderating role of innovative climate.

The main objective of this research is to examine whether the implementation of new human resource management practices (NHRM) can enhance innovative performance (IP) by fostering innovation capability (NC). Additionally, it examines the moderating influence of an innovative climate (IC) and its associated attributes on the association with new human resource management and innovation capability, a factor that has been relatively overlooked in prior research. The study's data was obtained from 398 employees in the pharmaceutical sector of Pakistan, and hierarchical regression analysis was utilized to analyze the data. The results from the mediating and moderating analyses underscore the significance of NHRM practices, innovation capability, and an innovative climate, along with its specific attributes, in promoting innovative performance through factors such as operational efficiency, suitable practices, and employees' willingness to participate in organizational endeavors. Furthermore, the moderated mediation analysis findings reveal that the influence of innovation capability as a mediator is strengthened when the workplace climate is more conducive to innovation. These findings have implications for both theoretical understanding and practical application, particularly in similar developing countries. The study offers insights that can be generalized to developing nations with comparable economic and social structures.

A Systematic Critical Review of Clinical Pharmacokinetics of Torasemide.

PURPOSE: Torasemide is a potassium-sparing loop diuretic used to treat fluid retention associated with congestive heart failure and kidney and hepatic diseases. This systematic review was conducted to combine all accessible data on the pharmacokinetics (PK) of torasemide in healthy and diseased populations, which may help clinicians avert adverse drug reactions and determine the correct dosage regimen. METHODS: Four databases were systematically searched to screen for studies associated with the PK of torasemide, and 21 studies met the eligibility criteria. The review protocol was registered in the PROSPERO database (CRD42023390178). RESULTS: A decrease in maximum plasma concentration (C max ) was observed for torasemide after administration of the prolonged-release formulation in comparison to that after administration of the immediate-release formulation, that is, 1.12 ± 0.17 versus 1.6 ± 0.2 mcg/mL. After administering an oral dose of torasemide, a 2-fold increase in the area under the concentration-time curve (AUC) was reported in patients with congestive heart failure compared with the healthy population. Moreover, the patients with renal failure (clearance < 30 mL/min) showed an increase in value of AUC 0-∞ that is, 42.9 versus 8.091 mcg.h -1 .mL -1 compared with healthy subjects. In addition, some studies have reported interactions with different drugs, in which irbesartan showed a slight increase in the AUC 0-∞ of torasemide, whereas losartan and empagliflozin did not. CONCLUSIONS: The current review summarizes all available PK parameters of torasemide that may be beneficial for avoiding drug-drug interactions in subjects with renal and hepatic dysfunction and for predicting doses in patients with different diseases.

Prevalence Of Second Mesiobuccal Canal In Maxillary Second Molars On The Basis Of Clinical And Radiographic Parameters.

BACKGROUND: The objective of this study was to determine the prevalence of the second mesiobuccal canal in permanent maxillary second molar in patients presenting to Peshawar Dental College and Hospital. METHODS: One hundred and twenty patients advised for root canal treatment in the maxillary second molars participated in the study. Two detection procedures, clinical and radio graphical examination were used. Two pre-operative radiographs with different angulations and one post-operative radiograph were taken to examine roots and root canals. Access cavities were prepared and the second mesiobuccal canal was explored using magnifying dental loupes (3.5 x), endodontic explorer (DG16) and size 10 K-file. Descriptive statistics were recorded as percentages, frequencies and mean. The chi-square test was used for gender, age-wise comparison and right and left side of the maxillary jaw. RESULTS: One hundred and twenty patients were recruited in the study. There were 65 (54.2%) males and 55 (45.8%) females. The second mesiobuccal canal was more common in males compared to females (p-value=0.434). The second mesiobuccal canal was most commonly found in 3rd decade with mean age, of 40.5±12.31, (p-value =0.51). The frequencies and percentages of the second mesiobuccal canal in maxillary second molars on the right and left side of the jaw were 70 (58.3%) and 50 (41.7%) respectively (p-value =0.310). CONCLUSIONS: The second mesiobuccal canal was found in less than half of the second molars. The most successful method of detection in this study was both clinical and radiographic.

Assessment of immunization status and barriers to vaccination among the university students of Pakistan

A cross-sectional study was conducted to determine the vaccination status and barriers to vaccination among the university students by utilizing a simple random sampling technique in the largest public sector university of Southern Punjab, Pakistan. The participants comprised 380 university students. Data was collected by a self-designed questionnaire. Statistical Package for Social Sciences (SPSS) was used for data analysis. Chi-square Test and Fischer Exact test were applied to assess the impact of demographics on vaccination status, and barriers to vaccination. Out of 380 participants, 328 (86.31 pewrcent) were males and 52 (13.68) females. The immunization status of university students against various diseases was variable: 97.10 percent (n=369) were vaccinated against poliomyelitis, 58.68 percent (n=223) against BCG, 44.21 percent (n=168) against hepatitis B, 49.21 percent (n=187) against diphtheria, pertussis and tetanus and 55.26 percent (n=210) against measles vaccine. The barriers to vaccination were unwillingness 15.0 percent (n=57), inaccessibility 17.10 percent (n=65), financial issues 4.47 percent (n=17) and unawareness 63.42 percent (n=241). Moreover, 31 percent (n=118) of the participants considered that the use of vaccines is unsafe. The vaccination status of the university students in Southern Punjab, Pakistan is alarming as most of the students were unvaccinated. The unawareness and perception of the unsafety of vaccines were the biggest barriers to vaccination(AU)
