Objective: To assess the impact and effectiveness of a pan-genotypic Directly Acting Antiviral (DAA) based regimen for patients with chronic Hepatitis-C (HCV) infection in our setup. Study Design: Cross-sectional study. Place and Duration of Study: Departments of Pathology and Medicine, Combined Military Hospital, Malir, Karachi, from Dec 2019 to Jan 2021. Methodology: Sofosbuvir and Daclatasvir were administered orally at 400mg and 60mg daily, respectively, with or without Ribavirin to treatment-naïve and treatment-experienced adult patients with chronic HCV infection. End-of-treatment response and Sustained virological response were determined among these patients by monitoring viral load using quantitative HCV RNA PCR and various genotypes. Results: Of the 59 patients, 39(66%) patients received sofosbuvir (SOF)+Daclatasvir (DCV), 12(20.3%) patients were placed on SOF+Ribavirin (Rib) and 8(13.5%) were given triple regime of SOF+DCV+Rib for 12 and 24 weeks respectively. Most of our patients were females, 32(54.23%), with a mean age of 31±17 years. Forty-eight patients (81.35%) were infected with genotype 3, followed by genotype 1 and 2, respectively. The rapid viral response was noted after four weeks of therapy among 27(45.76%) patients. The sustained viral response was noted in 38(64.40%) and 21(35.59%) patients after 12 and 24 weeks, respectively. The end-of-treatment response was observed in 40(67.8%) patients. Conclusion: Direct-acting antiviral-based regimens have shown favourable results with fewer adverse effects in our patients.

Objectives: To determine the frequency of parasites detected in stool samples of children with symptoms of parasitic infections. Study Design: Cross-sectional study. Place and Duration of Study: Department of Microbiology, Armed Forces Institute of Pathology, in collaboration with Paediatrics Department of Pak Emirates Military Hospital, Rawalpindi Pakistan, from Jan to Jul 2020. Methodology: A Total of 138 stool samples were collected from children who were admitted or presented in the outdoor department and had symptoms of intestinal parasitic infections. Youngsters who had been dewormed within the previous six months or whose samples arrived at the lab more than three hours after the collection were not included. Stool samples were examined visually and by using a saline preparation followed by a method that involved the concentration of formal ether. This was done to determine the different kinds of trophozoites, adult worms, and eggs or cysts that parasites produce. Results: The study found that intestinal parasites were moderately prevalent (26.81%) among the pediatric population, with Giardia lamblia (54.05%) being the most frequent, followed by Entamoeba histolytica (35.14%) and Ascaris lumbricoides (5.41%). Conclusion: It is recommended to guarantee the accessibility of purified drinking water to decrease the incidence of parasitic infections within our populace.

Objective: To determine the association between elevated serum prolactin and the development of gestational diabetes mellitus in the first trimester. Study Design: Prospective longitudinal study. Place and Duration of Study: Pathology Department, Combined Military Hospital, Quetta Pakistan, from Apr 2021 to Mar 2022. Methodology: One hundred and twenty-one patients had a measurement of serum prolactin in the first trimester, along with an oral glucose tolerance test in the second and third trimester, at the Pathology Department Combined Military Hospital Quetta Pakistan. Results: In the study group, serum prolactin levels were raised in 51(42.1%) patients in the first trimester. A total of 44(36.3%) patients with raised serum prolactin had impaired oral glucose tolerance tests. A significant association was found between raised serum prolactin and subsequent development of gestational diabetes mellitus in pregnant females. Conclusion: Serum prolactin can be an important biomarker for early diagnosis and monitoring of gestational diabetes mellitus.

Objective: To study the patterns and distribution of various abnormal semen parameters in infertile males. Study Design: Cross sectional study. Place and Duration of Study: Department of Pathology, Combined Military Hospital, Karachi, from Nov 2019 to Oct 2020. Methodology: The study included 364 patients who presented with primary and secondary infertility. Consecutive convenient sampling was done. Semen analysis was performed using World Health Organization latest guidelines. Samples were categorized as normospermia, azoospermia, oligospermia, asthenozoospermia and necrospermia. Results: The study comprised of 364 samples of infertile males. Normal sperm count was observed in 317 (87%) males, azoospermia in 28 (7.6%) and oligospermia in 19 (5.2%) males. Low ejaculated volume and higher non-motile sperms were noted in oligospermia samples in comparison with normospermia samples. Asthenozoospermia was observed in 102 (28%) and oligoasthenospermia was noted in 15 (4.1%) samples. Conclusion: Good quality semen analysis is a corner stone to diagnose the cause of male infertility. Sperm concentration and motility are the important markers of normal male reproductive system and are related to each other.

Three Cenchrus species (C. biflorus, C. ciliaris, and C. orientalis) were collected from different ecological regions in the Punjab and Khyber Pakhtoonkhwa during July to September 2020 to evaluate tolerance to multiple abiotic stresses (aridity, salinity, and cold). Growth and biomass production was the maximum in C. biflorus, C. ciliaris, and C. orientalis under aridity stress. Aerenchyma formation and vascular tissue increased significantly in roots under aridity. In C. ciliaris, aerenchyma formation was recorded under cold stress. Root vascular tissue was higher under normal conditions (26.7%) and aridity (30.4%) stress in C. ciliaris. Stem parenchyma (29.1%) and vascular tissues (35.5%) showed an increase in C. biflorus under aridity, while mechanical tissue (33.6%) increased significantly under salinity stress. In C. biflorus and C. ciliaris, extensive sclerification was recorded in the stelar region under aridity stress. The stem radius of C. orientalis was greatest under salinity (27.0%) and cold (29.1%) stress, while parenchyma tissue was smaller (12.1%) under cold stress. Leaf thickness generally increased under abiotic stresses, and the maximum (43.0%) thickness was recorded in C. biflorus under aridity stress. Cenchrus biflorus, C. ciliaris, and C. orientalis showed strong association among morphological and leaf anatomical traits under aridity stress. Cenchrus orientalis showed high sclerification outside the vascular bundles of the leaf sheath. In saline conditions, vascular bundles were sclerified and enlarged. In and outside the vascular bundles of leaf blades, extensive sclerification was observed under cold stress conditions. Modifications in structural and functional traits were critical for the ecological success of Cenchrus species for survival in multiple environmental stresses. [ABSTRACT FROM AUTHOR]

Salt excretory halophytes are the major sources of phytoremediation of salt-affected soils. Cressa cretica is a widely distributed halophyte in hypersaline lands in the Cholistan Desert. Therefore, identification of key physio-anatomical traits related to phytoremediation in differently adapted C. cretica populations was focused on. Four naturally adapted ecotypes of non-succulent halophyte Cressa cretica L. form hyper-arid and saline desert Cholistan. The selected ecotypes were: Derawar Fort (DWF, ECe 20.8 dS m−1) from least saline site, Traway Wala Toba (TWT, ECe 33.2 dS m−1) and Bailah Wala Dahar (BWD, ECe 45.4 dS m−1) ecotypes were from moderately saline sites, and Pati Sir (PAS, ECe 52.4 dS m−1) was collected from the highly saline site. The natural population of this species was collected and carefully brought to the laboratory for different structural and functional traits. As a result of high salinity, Na+, Cl–, K+, and Ca2+ content significantly increased at root and shoot level. At root level, some distinctive modifications such as increased sclerification in vascular bundles, enlarged vascular bundles, metaxylem vessels, phloem region, and storage parenchyma (cortex) are pivotal for water storage under extreme arid and osmotic condition. At the stem level, enhanced sclerification in outer cortex and vascular bundles, stem cellular area, cortical proportion, metaxylem and phloem area, and at the leaf level, very prominent structural adaptations were thicker and smaller leaves with increased density of salt glands and trichomes at surface, few and large stomata, reduced cortical and mesophyll parenchyma, and narrow xylem vessels and phloem area represent their non-succulent nature. The ecotype collected from hypersaline environments was better adapted regarding growth traits, ion uptake and excretion, succulence, and phytoremediation traits. More importantly, structural and functional traits such as root length and biomass, accumulation of toxic ions along with K+ in root and shoot, accumulation of Ca2+ in shoot and Mg2+ in root, excretion of toxic ions were the highest in this ecotype. In conclusion, all these alterations strongly favor water conservation, which certainly contributes to ecotypes survival under salt-induced physiological drought. Naturally adapted salt tolerant plants provide exceptional material for exploring adaptive mechanisms they use to confront high salt concentrations. Cressa cretica is a hypersaline hyperarid desert colonizer, which was previously underexplored. In the present study, we focused on the new insight on relationship among anatomical modifications, salt accumulation and excretion and phytoremediation potential of this rare species.

During inflammation and situations of cellular stress protein disulfide isomerase (PDI) is released in the blood plasma from the platelet and endothelial cells to influence thrombosis. The addition of exogenous PDI makes the environment pro-thrombotic by inducing disulfide bond formation in specific plasma protein targets like vitronectin, factor V, and factor XI. However, the mechanistic details of PDI interaction with its target remain largely unknown. A decrease in the coagulation time was detected in activated partial thromboplastin time (APTT), prothrombin time (PT), and thrombin time (TT) on addition of the purified recombinant PDI (175 nM). The coagulation time can be controlled using an activator (quercetin penta sulfate, QPS) or an inhibitor (quercetin 3-rutinoside, Q3R) of PDI activity. Likewise, the PDI variants that increase the PDI activity (H399R) decrease, and the variant with low activity (C53A) increases the blood coagulation time. An SDS-PAGE and Western blot analysis showed that the PDI does not form a stable complex with either thrombin or antithrombin (ATIII) but it uses the ATIII-thrombin complex as a template to bind and maintain its activity. A complete inhibition of thrombin activity on the formation of ATIII-thrombin-PDI complex, and the complex-bound PDI-catalyzed disulfide bond formation of the target proteins may control the pro- and anti-thrombotic role of PDI.

Purpose: The research study was designed with the sole aim to explore the food security status in the purview of women’s rights in the District Tor Ghar, KP, Pakistan Approach: A sample size of 291 out of 760 household heads was selected randomly from 3 villages of Khander Tehsil namely Bilyani, Bimbal, and Dharo. The conceptual framework comprised of an independent variable (availability of food) and one dependent variable (food insecurity). Data on study variables were collected using the Likert scale. The Chi-square test was applied to test the strength of association among study variables. Findings: The study found that the limited availability of vegetables, fruits, bread, and meat required for a daily meal for women alongside sufficient milk/ dairy products and dry fruit to feed women at home, were found significant (p

To implement sustainable water resource management, the industries that produce a huge amount of wastewater are aiming to recycle wastewater. Reverse osmosis (RO) is an advanced membrane process that can produce potable water from wastewater. However, the presence of diverse pollutants in the wastewater necessitates effective pretreatment to ensure successful RO implementation. This study evaluated the efficiency of microfiltration (MF) and ultrafiltration (UF) as two pretreatment methods prior to RO, i.e., MF-RO and UF-RO, for recycling poultry slaughterhouse wastewater (PSWW). The direct treatment of PSWW with RO (direct RO) was also considered for comparison. In this study, membrane technology serves as a post treatment for PSWW, which was conventionally treated at Sanderson Farm. The results demonstrated that all of the processes, including MF-RO, UF-RO, and direct RO treatment of PSWW, rejected 100% of total phosphorus (TP), over 91.2% of chemical oxygen demand (COD), and 87% of total solids (TSs). Total nitrogen (TN) levels were reduced to 5 mg/L for MF-RO, 4 mg/L for UF-RO, and 9 mg/L for direct RO. In addition, the pretreatment of PSWW with MF and UF increased RO flux from 46.8 L/m2 h to 51 L/m2 h, an increase of approximately 9%. The product water obtained after MF-RO, UF-RO, and direct RO meets the required potable water quality standards for recycling PSWW in the poultry industry. A cost analysis demonstrated that MF-RO was the most economical option among membrane processes, primarily due to MF operating at a lower pressure and having a high water recovery ratio. In contrast, the cost of using RO without MF and UF pretreatments was approximately 2.6 times higher because of cleaning and maintenance expenses related to fouling. This study concluded that MF-RO is a preferable option for recycling PSWW. This pretreatment method would significantly contribute to environmental sustainability by reusing well-treated PSWW for industrial poultry purposes while maintaining cost efficiency.

Alkylation of N‐substituted imidazoles ImR' (R'=2,4,6‐trimethylphenyl, 2,6‐diisopropylphenyl, 1‐adamantyl) with Mn(I) methylenephosphonium complexes [Cp(CO)2Mn(η2‐P,C‐R2P=C(H)Ph)](BF4) (PR2=PPh2, PCy2, trans‐PC(H)PhCH2CH2C (H)Ph) followed by photochemical demetallation afforded a series of bidentate NHC‐phosphine ligand precursors [R2PC(H)PhImR'](BF4) in moderate to good yield. The same strategy was successfully applied to N‐functionalized imidazoles ImL (L=2‐pyridyl, CH2SMe, CH2ImMe) to afford selectively NHC core pincer pre‐ligands featuring phosphine/thioether, phosphine/NHC and phosphine/pyridine side arms. For PCy2 derivatives, free NHCs in both bidentate and pincer series generated by deprotonation of the corresponding cationic precursors were shown to be persistent at room temperature.

This study examines the nexus between oil prices (Oil) and economic output (IIP) asymmetrically in the Indian context using quarterly data from 1996–1997:Q1 to 2019–2020:Q4. To this end, we have used a nonlinear autoregressive distributed lag (NARDL) model. The main findings of the study are as follows—firstly, the Wald test confirms the nonlinearities among the negative and positive shocks in Oil, EX and IR in the long run. Secondly, the NARDL model reveals that negative shock in oil price stimulate the IIP, whereas positive shock in Oil fails to influence IIP. The positive shock in EX strengthens the Indian economy by having a positive and significant impact on IIP, while the negative shock in EX is insignificant. The positive and negative shocks in IR negatively impact IIP in the long run. The study demonstrates that Oil, EX and IR exert asymmetric pressure on IIP in the long run. Concisely, India's economic output is more responsive to oil prices decrease than oil prices increase. Therefore, the asymmetric oil prices‐economic output nexus has substantial policy implications, particularly for prudent energy policy in India. [ABSTRACT FROM AUTHOR]
