Simple Summary: Livestock herding is an essential and time-honored practice in Balochistan, playing a pivotal role in the region's economy, culture, and way of life. The livestock sector is of utmost important in the province, catering to nearly 20% of the national stock. Over centuries, large predators and their prey species, including livestock, have coexisted in these mountainous landscapes. Consequently, large carnivores are more likely to interact with humans due to their extensive home ranges. This research aims to explore the impact of livestock depredation by large predators on livelihoods and conservation efforts in two districts of Balochistan, Pakistan. A human–carnivore conflict survey was conducted from July to September 2019, gathering data from 311 residents in the selected study area. Large predators in the region preyed on a total of 876 livestock over a year, comprising 560 goats, 292 sheep, 19 cows, and 5 donkeys. The gray wolf emerged as the primary predator, accounting for 66.3% of livestock depredation, which was followed by the caracal (24.3%), Asiatic jackal (8.9%), and striped hyena (0.6%). The economic loss totaled USD 78,694. Notably, 80% of respondents held negative perceptions toward wolves compared to 24.4% for caracals. Only 20.6% of respondents were aware of the importance of conserving carnivores. Livestock depredation by carnivores has fostered negative perceptions among locals toward these animals. There exists a lack of awareness regarding the significance of conserving carnivore species and their ecological roles. It is crucial to raise awareness among communities about the ecological importance of predators like the gray wolf, caracal, Asiatic jackal, striped hyena, and Balochistan black bear through community meetings and educational seminars. Furthermore, providing basic education to herders on effective livestock guarding practices is recommended to mitigate human–carnivore conflicts and promote coexistence between wildlife and local communities in Balochistan. Livestock herding is a vital practice in Balochistan, contributing to the economy and culture. The livestock sector is significant in Balochistan, providing 20% of the national stock. Large predators and their prey species, including livestock, have coexisted in these mountainous landscapes for centuries. The aim of the present research is to investigate the impacts of livestock depredation by large predators on livelihoods and predator conservation in two districts of Balochistan, Pakistan. A human–carnivore conflict survey was conducted from July to September 2019, collecting data from 311 residents in a selected study area. Large predators in the study area preyed on a total of 876 livestock during a one-year period, including 560 goats, 292 sheep, 19 cows, and 5 donkeys. The gray wolf is the leading predator, responsible for 66.3% of livestock depredation, followed by the caracal (24.3%), Asiatic jackal (8.9%), and striped hyena (0.6%). The total economic loss was USD 78,694. Overall, 80% of respondents had a negative perception of wolves compared to 24.4% for caracals. Only 20.6% of respondents knew about the importance of conserving carnivores. Livestock depredation by carnivores in the study area created a negative perception of these animals among people. There is a lack of awareness about the importance of conserving carnivore species and their role in the ecosystem. This lack of understanding has ultimately led to detrimental effects on predator populations. It is imperative to raise awareness among people about the ecological significance of carnivores through community meetings, seminars in educational institutions, and providing basic education to herders about effective livestock guarding practices.

Background: Rheumatoid arthritis (RA) is an immune-mediated, polyarthritis linked with various genetic and environmental causative agents. Among environmental triggers, Epstein-Barr Virus (EBV) is considered the most potent etiological agent. Objective: This study aimed to investigate the prevalence of EBV and its genotypes in RA patients and to investigate their association with clinical and laboratory parameters of RA. Methodology: This study included blood samples of RA and control healthy individuals (100 each). Blood samples along with clinical and laboratory parameters were collected from patients after consent in the Department of Rheumatology, at Lady Reading Hospital, in Peshawar Pakistan. Blood samples were processed for DNA extraction followed by PCR amplification for EBV detection and genotype discrimination. Results: RA patients were 85 females and 15 males with a mean age of 40.13±14.05 years. EBV Type-1 was detected in 45% of RA and 9% of control cases. The mean disease duration of RA patients was 6.61±6.23 years. Out of 100 diseased patients, 43% were seropositive rheumatoid arthritis (SPRA) and showed a significant correlation with a family history of RA in EBV-positive individuals (P = 0.017). The demographic, clinical, and laboratory parameters of RA patients showed a non-significant association with EBV. Moreover, only a family history and Serum creatinine of RA patients showed a significant association with EBV (P = 0.0001 and P = 0.022 respectively). Conclusion: It is concluded that EBV-1 is prevalent and associated with RA. Further investigation is required for detailed genetic analysis of EBV to determine its possible role in modulating the immune system in RA. [ABSTRACT FROM AUTHOR]

In Pakistan, jinn afflictions reveal the maddening effects of displacement, economic inequality, and household conflicts. In this article, I consider how healers treat conditions of the nafs (soul), specifically its impurity and corruption through material desires, as enhancing the susceptibility of clients to jinn affliction where healers prescribe engagement in pietistic activities and active remembrance of God (ẕikr) as a means of keeping the effects of spirits and the symptoms caused by them at bay. Healing also involves domesticating spirits and making them habitable with their human counterparts, as antagonistic relations between the two are seen as causes of acute symptoms (dauray). This process requires a range of negotiations with jinns, including efforts to convert them to Islam. The condition of the nafs and its continual purification are seen as necessary to ensure a peaceful relation between the jinn and the client, which is possible mainly by drawing upon the authority of Sufi lineages. Nafs and its relationship with spirits provide an opportunity to think about illness through relations between mind and the heart as well as the self and the other. [ABSTRACT FROM AUTHOR]

In Baltimore, clients in methadone maintenance treatment (MMT) experiment with prescription medicine and in doing so face new risks of noncompliance as they tread this blurry line between medical and illegal. This can potentially lead to suspension from drug treatment programs, resulting in clients finding the next most suitable treatment center to enroll into. I argue that the close interaction between drug treatment centers and illegal markets results in new pharmaceutical dependencies, forms of self-care as well as suspicions toward, but also among clients, about their intentions to recover.

The Siachen glacier, one of the longest non-polar glaciers in the world, turned into the world's highest battlefield in 1984, when both the neighbouring countries, India and Pakistan, deployed their troops for control over the glacier. The nature of warfare since then has changed from active operations to one of low-intensity warfare. In this changing nature of warfare, the article explores how meanings of death are reconfigured in personal recollections and public representations, when the terrain continues to inflict injuries, high-altitude illnesses and death in the absence of any direct enemy confrontation. The article compares personal experiences of death with media representations. While personal experiences of soldiers and officers who have served on the glacier show their grievances about having left comrades to die after they fell into deadly crevasses, media representations reinsert the Indian soldier and depict death in the company of comrades and family to justify the expensive and extremely difficult war over the glacier.

The article considers several generations of Pakistani immigrants from Karachi to various cities in the United States such as Chicago and New York and explores how chronic diseases are shaped by the reverberations of conflict in kin relations in the US and Pakistan. Instead of examining the experience of chronic illness in isolation, the article considers how webs of evolving relations, tensions, competition, and conflicts among distant and close kin are experienced by the vulnerable and those who try to care for them. These conflicts are shaped by the experience of absence and also in the lives of intimate kin, and often appear in violent form. In navigating these relations, caregivers of those with illnesses develop strategies to maintain communications with wider kinship networks while also shielding the sick from the ramifications of ongoing disputes.

Diclofenac sodium was extensively used for treating arthritis, osteoarthritis and skeletal muscular injuries, which ultimately caused troubles for aquatic organisms as well as human beings. In this study, homogeneous catalytic advanced oxidation processes, including Fe2+/persulfate, Fe2+/peroxymonosulfate and Fe2+/H2O2, were used for the degradation of diclofenac sodium in water, without using UV-C light. About 89, 82 and 54% DCF sodium was decomposed by Fe2+/persulfate, Fe2+/peroxymonosulfate and Fe2+/H2O2, respectively, in 60 min. The degradation of diclofenac sodium followed the pseudo first-order kinetics, in all cases. The degradation efficiency of diclofenac sodium was significantly affected in the presence of various anions, such as NO3−, HCO3− and SO42−. The mineralization studies revealed 62, 45 and 32% total carbon removal by Fe2+/persulfate, Fe2+/peroxymonosulfate and Fe2+/H2O2, respectively, in 60 min. In addition, the degradation byproducts of diclofenac sodium were determined by FTIR analysis. The results revealed that the Fe2+/oxidant system, particularly Fe2+/persulfate, was a promising technology for the elimination of toxic pharmaceuticals, such as diclofenac sodium, from the water environment.

The removal of water pollutants by photocatalysis is a promising technique, mainly due to its environmentally friendly and sustainable nature. In this study, the degradation of a recalcitrant organic pollutant, malachite green (MG), was investigated in water by a microstructured silver oxide photocatalyst. The silver oxide (Ag2O) microparticles (MPs) were synthesized by a low-cost, green method, mediated by green tea leaves extract. The surface, morphological and optical properties of the synthesized Ag2O MPs were determined by scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, X-ray diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy, and ultraviolet-visible (UV-visible) spectrophotometry. The synthesized Ag2O MPs showed good photoactivity, represented by 83% degradation of malachite green (MG) ([C]0 = 0.4 mM, Ag2O loading = 0.1 g L−1) at neutral pH, in 3 h. Persulfate ions (PS) showed a strong synergistic effect on the efficiency of solar/Ag2O photocatalysis, represented by complete MG removal in 15 min, in the presence of 1.6 mM PS. The results revealed that solar/Ag2O, particularly solar/Ag2O/PS photocatalysis is a promising method for the elimination of toxic organic pollutants, such as malachite green, from the water environment.

The Helicobacter pylori have ancestral relation with the family of Proteobacteria, order Campylobacterales, family Helicobacteraceae. It is the first and most important cause of gastric carcinoma along with peptic ulcer and dyspepsia carcinoma. H. pylori is also responsible for mucosa associated with lymphoid tissue (MALT) and Known Hodgkin Lymphoma. It is assessed that patients having H. pylori are a 30% to 40% possibility of evolving gastric ulcer and a 10% to 20% possibility of developing distal gastric cancer. It causes chronic inflammation and significantly increases the risk of duodenal, gastric ulcer, and cancer. It is the second leading cause of cancer-related deaths in the world. In the current study, a total of 210 gastric biopsy specimens were collected from the patient with a history of gastritis from Chughtai Lab in 10% NBF. All tissue size was measured and gross examined these samples were processed in an automated tissue processor Tissue-Tek VIP VI (Japan). After processing, the embedding of tissues was done in paraffin wax at Tissue-Tek TEC. 2- 3 µm sections were prepared using rotary microtome Leica 201 USA. A comparison was carried out between H&E and IHC. Helicobacter pylori were detected in 88 cases out of 200 while 09 samples were either poorly preserved or autolyzed that's why further processing and diagnosis were not possible. One case was diagnosed as poorly differentiated adenocarcinoma; the sample was collected from a female patient of 56 years. Out of 88 positive cases, 66 (75%) were initially screened as positive for H.pyloriby H&E staining due to the presence of mild or moderate colonization while the remaining 25% cases were negative by H&E staining but with suspicion of neutrophils and lymphoid aggregates. All 88 cases were further confirmed by IHC. Our findings confirmed that IHC is a batter reliable and more accurate method in the diagnosis of H.pylori and it should be considered the gold standard.

Photocatalysis is a promising process for decomposing harmful organic pollutants in water. In this study, solar/photocatalytic degradation of two model azo dyes, i.e., methylene blue (MB) and methyl red (MR), in water usinga nanostructured chitosan-modified nickel magnetite (CS-NM) bio-composite was investigated. The CS-NM bio-composite was synthesized through a co-precipitation method and characterized by Fourier transform infrared (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), thermogravimetry (TGA), and UV-Vis spectroscopy. FTIR analysis showed the uniform incorporation and conjugation of nickel magnetite (NM) into the chitosan (CS) polymer matrix. SEM showed that the average particle size was 0.5 μm. The TGA results revealed the good thermal stability of the prepared bio-composite at 300 °C. The point of zero charge was calculated as 7.5. The effect of water quality and process parameters, such as concentration of dyes, catalyst dose, solution pH, and temperatures, was investigated, for application purposes. The solar/CS-NM photocatalysis resulted in 99 and 96% degradation of individual MB and MR (C0 = 50 ppm), respectively, in 90 min. The degradation of MB and MR by solar/CS-NM photocatalysis followed pseudo-first-order kinetics, with observed rate constants (k) of 0.077 and 0.072 min−1, respectively. The CS-NM photocatalyst showed high recyclability, represented by only a 4–6% loss in the photocatalytic efficiency, after four cycles. The results showed that solar/CS-NM photocatalysis is an efficient technique for degrading recalcitrant organic pollutants, such as azo dyes, in water environments. [ABSTRACT FROM AUTHOR]

Indian squash (Praecitrullus fistulosus) crop faces heat and drought during its growth that is considered the most important abiotic stress in semi-arid areas. Seed priming with growth regulators enhances stress tolerance; hence, mitigates the adverse effects of unpredictable stresses due to adverse weather conditions. This two-year (2019 and 2020) study was conducted to infer the role of seed priming in improving heat tolerance of Indian squash (cultivar Sahavi) through improvement in physiological and antioxidant defense systems. Six treatments that included no priming (control), hydropriming, priming with indole acetic acid (IAA) at 100 mg L-1, salicylic acid (SA) at 50 mg L-1, ascorbic acid (AA) at 100 mg L-1 and thiourea at 500 mg L-1 each for 06 hours) were included in the study. Results revealed that priming with AA and SA significantly (P ≤ 0.05) enhanced germination (39 and 47%), germination index (57 and 58%), plant height (23 and 22%), vine length (15 and 14%), number of fruits per plant (62%), fruit weight per plant (66 and 67%), economic yield (32%), photosynthesis rate (18 and 17%), protein content (10%), proline (23%), glycine betaine (3%), malondialdehyde content (11 and 10%) and catalase activity (24%) compared to control treatment. Furthermore, seed priming with AA and SA significantly (P ≤ 0.05) shortened the mean germination time (25 and 28%) compared to the control. The results indicated that AA and SA had significant potential to mitigate adverse effects of heat stress in Indian squash. Findings from this study showed that seed priming with AA and SA promoted heat-stress tolerance and enhanced growth and productivity of Indian squash. [ABSTRACT FROM AUTHOR]

Interferon/Ribavirin therapy has been replaced by Direct Acting Antivirals (DAAs) due to emergence of Resistance Associated Variants (RAVs) and decrease Sustain Virologic Response (SVR). Current study investigated treatment response of Sofosbuvir and Ribavirin in chronic HCV patients. Total 256 HCV patients with genotype 1a, 2 and 3a received sofosbuvir/ribavirin according to international standards. HCV RNA presence in serum was used as marker for end treatment response (ETR) and sustain virologic response after 24 weeks of treatment (SVR24) in each case. Response to treatment with SOF + RBV was found statistically significant among different HCV genotypes (GT) as out of 47 HCV GT1 patients 42(89.36%) resulted into good ETR but 4(9.52%) of these relapsed and 5(10.63%) led into virologic failure. 5(100%) HCV GT2 patients resulted into SVR24 whereas, out of 204 HCV GT3 patients 194(95.69%) achieved good ETR however, 8(4.12%) of these relapsed and 10(4.90%) resulted in to virologic failure. Efficacy of therapy was found non-significant in treatment naïve and treatment experienced patients as in this study out of 145 treatment naïve patients 139(95.86%) achieved good ETR where 4(2.87%) relapsed while 6(4.13%) led into virologic break through on the other hand among 111 treatment experienced patients 102(91.89%) resulted into good ETR but 8(7.84%) relapsed whereas 9(8.10%) lead into virologic failure. Current study also propose that various liver and spleen complications/liver cirrhosis are related to response of HCV patients to SOF + RBV therapy whereas, variables like old age, gender is not compromising treatment response to DAAs therapy. Various mild side effects encountered by patients during treatment were fatigue, insomnia, headache, nausea, burning body, diarrhea, cough. Overall, this study reported 89.45% efficacy of SOF + RBV regime in chronic HCV Pakistani patients. Current study suggests hunting for possible reasons of resistance so that SOF + RBV therapy may not share the same fortune as previous therapies in near future. [ABSTRACT FROM AUTHOR]

Based on low density, Mg metal-based composites exhibit high specific mechanical properties and are actively used for weight critical structural application. In the present study, Mg-matrix based TiO2/Al2O3 composite materials were synthesized by using the powder metallurgy (Solid-phase) technique. Parameters such as the concentration of the components, temperature, and pressure were optimized before experiments. Different conditions such as temperature (30 °C) and pressure (760 mm of Hg) were also optimized. Pellets of the Mg-based composites and their pure constituent counterparts of various diameters (10–20 cm) were prepared under 50 tons of hydraulic pressure. Single-phase homogenous composites were obtained by undertaking the pellets through sintering in an electric furnace at elevated temperature (600 °C) for 1 h. The prepared materials were tested for different properties using various physicochemical techniques such as Fourier transform infrared spectroscopy (FTIR), Scanning electronic microscopy (SEM), X-ray diffraction (XRD) and Surface area analyzer. FTIR results confirmed composite formation. SEM revealed microstructures of all materials in the µm range. XRD proved the phase-distribution and crystallinity of the prepared materials. It was found that 2 and 3-component systems are homogenized when prepared by the powder metallurgy technique. The surface area of all materials was confirmed using the BET adsorption isotherm equation. The surface area of the prepared composites was found to be in the range from 40 to 70 m2/g. Such properties enable these materials for potential application in solar reflectance and as a catalyst in liquid phase hydrogenation. [ABSTRACT FROM AUTHOR]

Antibiotics are the most common pharmaceutical compounds, and they have been extensively used for the prevention and treatment of bacterial diseases for more than 50 years. However, merely a small fraction of antibiotics is metabolized in the body, while the rest is discharged into the environment through excretion, which can cause potential ecological problems and human health risks. In this study, the elimination of seventeen antibiotics from real livestock wastewater effluents was investigated by UV/TiO2 advanced oxidation process. The effect of process parameters, such as TiO2 loadings, solution pHs, and antibiotic concentrations, on the efficiency of the UV/TiO2 process was assessed. The degradation efficiency was affected by the solution pH, and higher removal efficiency was observed at pH 5.8 and 9.9, while the catalyst loading had no significant effect on the degradation efficiency at these experimental conditions. UV photolysis showed a good removal efficiency of the antibiotics. However, the highest removal efficiency was shown by the UV/photocatalyst system due to their synergistic effects. The results showed that more than 90% of antibiotics were removed by UV/TiO2 system during the 60 min illumination, while the corresponding TOC and COD removal was only 10 and 13%, respectively. The results of the current study indicated that UV/TiO2 advanced oxidation process is a promising method for the elimination of various types of antibiotics from real livestock wastewater effluents.

Objective: The aim of this study is to present six cases of cervical lymphadenopathy, diagnosed as Kikuchi's disease and raise the index of suspicion for this disease. Study Design: Case Series. Setting: Histopathology and Otolaryngology/Head & Neck Surgery Department at Rehman Medical Institute (RMI) Peshawar. Period: July 2016 to March 2021. Material & Methods: Records of patients for cases diagnosed as "histiocytic necrotising lymphadenitis" were retrieved, their corresponding patient files accessed from the archive, and case notes analyzed. Results: In this series, a total of six cases of Kikuchi's disease are presented. A female predominance is evident from the present data (2:1 female to male ratio). All patients presented with palpable lymph nodes in the neck, predominantly on the left (66.7%). Majority (66.7%) presented with neuralgic pain (on/off). Only one patient did not show weight loss and night sweating, the remaining had all the symptoms. All of the patients recovered spontaneously within 6 months (range 2 to 6 months) with symptomatic treatment for neuralgic pain. Conclusion: Kikuchi's disease should be kept in the differential diagnosis in young females with persistent neck masses, palpable lymph nodes and suspicious fine needle aspiration cytology (FNAC).

Omapatrilat, the most clinically advanced member of a new class of cardiovascular agents, vasopeptidase inhibitors, is under development at Bristol-Myers Squibb Pharmaceutical Research Institute for the treatment of hypertension and heart failure. An electrospray LC/MS/ MS method has been developed and validated for the simultaneous determination of omapatrilat and its four metabolites in human plasma. Since omapatrilat and two of the metabolites are sulfhydryl-containing compounds, methyl acrylate was used to stabilize these compounds in human blood and plasma samples. Methyl acrylate reacted instantly with the sulfhydryl group to form a derivative that was stable in blood and plasma. Extraction of the analytes from plasma samples was achieved by semiautomated liquid--liquid extraction, where a robotic liquid handler performed the liquid-transferring steps. The mass spectrometer was operated in the negative ion selected-reaction-monitoring mode. The calibration curve ranges were 0.5-250 ng/mL for omapatrilat and one metabolite and 2.0-250 ng/mL for the other three metabolites.

Background: Hepatitis B Virus (HBV) is one of the most common human infectious agents, and the mutations in its genome may cause chronic hepatitis (CH), liver cirrhosis (LC), and hepatocellular carcinoma (HCC). This study was designed to characterize the enhancer-II (Enh-II) region of X gene in HBV positive patients to assess the association of such mutations with CH, LC, and HCC. Methods: HBV positive samples (N = 200) with patients' demographic and clinical data were collected from different regions of Khyber Pakhtunkhwa (KP), Pakistan. The Enh-II region of the HBx gene was sequenced and zanalyzed for polymorphism associated with advanced liver disease. Univariate and logistic regression analyses were performed to evaluate potent mutations associated with a risk for LC and HCC. Results: HBV Enh-II region sequences analysis revealed 25 different mutations. The highest frequency of mutations S101F (62.2%), A102V/R/G/I (56.25%), M103L/A (68.75%)were found in HCC, followed in LC and CH patients as 57.1%, 42.8%, 28.52% 16%, 15.2% and 18.4% respectively. H94 deletion in the α-box of the Enh-II region, associated with a high risk of HCC was found in half of the HCC patients. This deletion was present in 28.5% of LC and 6.5% of CH patients. Importantly, the high frequency of some notable mutations such as E109A/Y, A110S/K, Y111D/E, and F112L was first time reported in the entire study population. The frequencies of these mutations were high in HCC (43.75%, 37.5%, 50% and 43.75% respectively) as compared to LC (14.28%, 14.28%, 28.2% and 42.8%) and CH patients (12.8%, 15.2%, 16.8% and 16% respectively). Conclusion: Mutations associated with LC and HCC are prevalent in the Enh-II region in Pakistani HBV isolates. The mutations found are alarming in CH patients as these may progress to LC and HCC in a large number of patients. [ABSTRACT FROM AUTHOR]

The treatment of injured Indian soldiers in Britain during WWI deployed particular ways of recording injuries and using them to make judgments about loyalty to the Imperial Army by assessing the soldier's ability to malinger. This was possible by using personal correspondences between soldiers and their families for ethnographic ends ie. to determine susceptibility to develop mental illness through a soldier's ethnic background and whether he was from the so-called 'martial races' or not. This classificatory knowledge as well as the suspicion towards exaggerated symptoms was also inherited by Indian psychiatry after partition. However, while these psychiatrists reproduced some colonial biases about susceptibility of illness, they were much more receptive to considering the social experience of patients including their kinship relations at home and in the military. By the end of WWII, symptoms came to be regarded as signs of recovery and readjustment to social relations to make a case for the lasting impacts of war on the soldier's mental and physical health.

Medicago denticulata is commonly used as a leafy vegetable, salad, and food ingredient. In this study, different doses of leaves aqueous extract of M. denticulata (MD) were fed to intoxicated rabbits with paracetamol (100, 200, and 300 mg/kg) for regular 21 days. The aqueous extract was evaluated for phenolic composition using HPLC‐DAD. Serum biochemical and hematological parameters were studied to check its activity. The liver was examined histologically and for antioxidant status. Results revealed that paracetamol led to a significant alteration in all the hematological (RBC, WBC, Hb, PLT, and HCT), and serum lipid parameters (TC, HDL, LDL, and TG) while MD at the dose rate of 300 mg/kg had a curative effect on the stabilization of the affected parameters. The high dose of MD ameliorated different antioxidant parameters such as reduced glutathione (GSH), DPPH radical scavenging activity (RSA), and thiobarbituric acid reactive substances (TBARS) of the liver on day 21st of the treatment. Histological studies revealed significant paracetamol‐induced toxicity of the liver, whereas the MD had positive effects on induced toxicity. Improvement in all these alterations confirms the curative potential of Medicago denticulata extract. Practical applications: Paracetamol is a well‐known antipyretic and analgesic medicine. However, it has been found to cause toxicity including hepatotoxicity. Synthetic drugs such as statins, antibiotics, and anti‐viral are used for curing hepatic diseases also cause severe side effects. Thus, nutraceuticals from plant foods are used to reduce the side effects of different hepatotoxic medicine are continuously researched. This study reported for the first time that aqueous extract of the plant leaves was protective against the hepatotoxicity induced by paracetamol. [ABSTRACT FROM AUTHOR]

Background: Understanding the genetic diversity of Plasmodium species through polymorphic studies can assist in designing more effective control strategies of malaria like new drug formulation and development of a vaccine. Pakistan is moderate endemic for Plasmodium falciparum , but little is known about the genetic diversity of this parasite. This study aimed to investigate the molecular diversity of P. falciparum based on msp-1 and msp-2 genes in the malaria-endemic regions of Khyber Pakhtunkhwa, Pakistan. Methods: A total of 199/723 blood samples, tested positive by microscopy for falciparum malaria, were collected from four districts (Dera Ismail Khan, Karak, Mardan, and Peshawar) of Khyber Pakhtunkhwa. Nested PCR amplification technique was employed to target block 2 of msp-1 and the central domain of msp-2 genes, including their respective allelic families K1, MAD20, RO33, FC27, and 3D7/IC, and to detect the extent of genetic diversity of P. falciparum clinical isolates. Results: Among the 199 microscopy-positive P. falciparum samples, a total of 192 were confirmed using PCR. Ninety-seven amplicons were observed for msp - 1 and 95 for msp-2. A total of 33 genotypes, 17 for msp-1 (eight K1, six MAD20, and three RO33) and 16 for msp-2 (nine FC27 and seven 3D7/IC), were identified. The specific allelic frequency of the K1 family was higher (44.3%) than that of MAD20 (33.0%) and RO33 (23.0%) for msp-1 , while the FC27 allelic family was dominant (60.0%) compared with 3D7/IC (40.0%) for msp-2. No polyclonal infection was observed in msp-1 and msp-2. The expected heterozygosity was 0.98 and 0.97 for msp-1 and msp-2 , respectively. Conclusion: It was concluded that the P. falciparum populations are highly polymorphic, and diverse allelic variants of msp-1 and msp-2 are present in Khyber Pakhtunkhwa, Pakistan.

Post-operative hypocalcaemia was the most common complication among retrosternal thyroidectomy patients (66.7%). Only one patient needed sternotomy. Conclusion: All patients with retrosternal goitre should be offered surgery. The post-operative complications are low and resolve uneventfully. [ABSTRACT FROM AUTHOR]

The analgesic, antidiarrheal, and neuro-pharmacological potentials of Medicago denticulata leaves extract were screened in animal models. Potential analgesic response was noted (*P < 0.05, **P < 0.01, ***P < 0.001) in formalin, acetic acid and heat-induced pain models in a dose-dependent manner. Maximum activity by means of writhing inhibition was documented for Medicago denticulata at 300 mg/kg that was found to be 71.79% (17.43 ± 1.31). In first phase, the Medicago denticulata at a dose of 150 and 300 mg/kg showed analgesic activity and reduced the pain by 54.18% (18.39 ± 1.67) and 62.90% (14.89 ± 1.56), respectively. In second phase, the Medicago denticulata at a dose of 150 and 300 mg/kg showed analgesic activity and reduced the pain by 69.48% (19.78 ± 1.44) and 70.89% (18.86 ± 1.58), respectively. In hot plate method, the Medicago denticulata at a dose of 150 and 300 mg/kg showed the maximum response of 61.16% (8.47 ± 1.23) and 67.39% (10.09 ± 1.04), respectively at 60 min. Scopolamine significantly reduces spontaneous alteration in Y-maze model for antiamnesic activity. Medicago denticulata significantly increased the discrimination index in a dose-dependent manner using novel object recognition test (NORT) model. Exploration time in sec for the novel object was increased significantly (P < 0.001) by donepezil decreased for familiar one with a discrimination index (DI) of 62.18%. Medicago denticulata significantly increased the discrimination index by 60.86% and 57.24% at 300 and 150 mg/kg b.w, respectively. The lowest DI of 53.80% at 75 mg/kg was observed in comparison to the amnesic group. The Medicago denticulata significant decreased the elevated levels of acetylcholinesterase (AChE) and malondialdehyde (MDA and enhancing level of acetylcholine (ACh), superoxide dismutase (SOD) and catalase (CAT) acting as an antioxidant agent. Medicago denticulata reduced the total number of diarrheal feces to lesser extent at dose-dependent manner. From the study results, it is suggested that the Medicago denticulata extract possess good analgesic and antiamnesic activity however the antidiarrheal effects of plant were negligible. In the current study, the traditional use of the plant as a source of medicine has been validated. [ABSTRACT FROM AUTHOR]

The decomposition of both [Alpha]- and [Beta]-anomers of ifetroban 1-O-acyl glucuronide in an aqueous medium was studied at ambient temperature (23 [degrees] C). An HPLC/MS technique was used to investigate the decomposition of these anomers via hydrolysis and acyl migration over a pH range of 1.0-13.0. It was found that while no acyl migration occurred at pH [less than or equal to] 4.0, hydrolysis occurred at both acidic and basic pH. The hydrolysis rate was the slowest within the pH range of 3.0-4.0. Outside this range, the rate of hydrolysis increased as the pH was increased or decreased. The acyl migration at pH 5.0 was very slow, but the rate increased as the pH was increased. First-order rate constants (in [h.sup.-1]), as a function of pH, were estimated according to a simplified scheme for both hydrolysis and acyl migration processes. Methanolysis of the [Beta]-anomer was studied in 80% or 100% methanol in water and also in 20% methanol in aqueous buffer solutions with apparent pH values of 3.0, 6.0 and 9.0. A systematic study of varying the pH and ionic strength of the HPLC mobile phase showed that both parameters significantly affected the resolution and retention times of the positional isomers and anomers. The HPLC method developed was capable of separating all the positional isomeric glucuronides and their anomers.
