Abstract
To identify potential scaffolds to treat gastritis and oxidative stress, 2-aryl-1H-naphtho[2,3-d]imidazole derivatives (1-15) were synthesized. The synthesis was conveniently carried out by condensing 2,3-diaminonaphthalene with variously substituted aldehydes to yield 15 new 2-aryl-1H-naphtho[2,3-d]imidazole derivatives. Structures of all synthesized compounds were elucidated using MS and NMR spectroscopic techniques. Compounds containing an imidazole moiety have continued to spark interest in the field of medicinal chemistry due to their unique properties. In continuation of this statement, to further explore the biological potential of these types of compounds, newly synthesized imidazole derivatives were evaluated for their inhibitory potential against urease and antioxidant activities. Compounds 4 and 11 were identified as the most potent urease inhibitors in the series, with IC50 values of 34.2 ± 0.72 and 42.43 ± 0.65 μM, respectively. Compounds 1, 3, 6, 11, and 15, with EC50 values in the range of 37-75 μg ml-1, showed significant antioxidant activity. Molecular docking studies of the selected synthesized compounds 3, 4, 9, and 11 were also performed to determine their binding interaction with the jack bean urease. Through docking studies, it was revealed that all the compounds that showed good inhibitory potential against urease fit well within the protein's binding pocket. Furthermore, ADME analysis was carried out to explore the drug-likeness properties of the compounds. The findings of the present work revealed that compounds 4 and 11 could be better options to treat gastritis and associated oxidative stress.

Abstract
Hepatobiliary fascioliasis is one of the rare but important parasitic infection in endemic areas such as Pakistan. Clinical manifestations overlap with common clinical conditions such as hepatitis and biliary stones causing common bile duct obstruction. Fascioliasis is a zoonotic infection caused by a leaf-shaped organism known as Fasciola Hepatica. Humans are accidentally infected by consuming contaminated water or food, especially undercooked cattle and sheep liver or raw green vegetables. We report three cases with similar clinical manifestations presenting in two different cities in Pakistan. After detailed clinical evaluation and laboratory investigations, the diagnosis was established by abdominal ultrasound and diagnostic and therapeutic cholangiography. Patients were followed till complete resolution of their symptoms and normalisation of liver function tests.

Abstract
Introduction Hepatocellular carcinoma (HCC) is frequently associated with portal vein thrombosis (PVT) with prevalence ranging from 25% to 50%. PVT is associated with poor prognosis, limiting the available therapeutic options for these patients. Our objective was to determine the prevalence and risk factors for PVT in patients with HCC. Method A retrospective analysis was performed on the prospectively collected data from January 2018 to March 2020. All patients with HCC discussed in our weekly multidisciplinary liver clinic were reviewed. Multivariate analysis was done to identify the independent risk factors for PVT in HCC patients. A p-value of <0.05 was considered significant. Result Of 316 patients, the prevalence of PVT was 31% (n = 98). Larger tumour size (p < 0.001), raised Alpha Fetoprotein (AFP) level (p = 0.036) and higher Child-Pugh class (p = 0.008) were significantly associated with PVT. In 216 patients with preserved liver function (Child-Pugh class A), PVT was seen in 53 (24.5%) patients. Large tumour size (p < 0.001) and higher AFP levels (p = 0.021) were independent risk factors. Conclusion Overall prevalence of PVT in HCC was 31% whereas 24.5% in patients with early cirrhosis (Child-Pugh class A). We identified various risk factors associated with PVT in our local population, highlighting the importance of early and regular screening of cirrhotic patients including Child-Pugh class A.

Abstract
Inhibition of α-amylase enzyme is of key significance for the therapy of diabetes mellitus (DM). Numerous indole-based compounds have earlier been described for broad range of bioactivities. From our previous study, we knew that indole and thiadiazole are potent inhibitors of diabetics II. We design the hybrid molecules of them and synthesized 18 derivatives of indole-based-thiadiazole (1-18). All synthesized compounds were characterized using different spectroscopic methods and evaluated for their α-amylase inhibitory activities. All synthetic compounds, except 4, 13, 15 and 16, were found to be strongly active (IC50 values in the range of 0.80 ± 0.05 - 9.30 ± 0.20 µM) than the standard drug, acarbose (IC50 = 11.70 ± 0.10 µM). Nevertheless, compound 18 was found to be inactive. The modes of binding interactions of five most active compounds 2, 3, 5, 10 and 17 were also studies through molecular docking study. In brief, current study identifies a novel class of α-amylase inhibitors which can be further studied for the treatment of hyperglycemia and obesity.Communicated by Ramaswamy H. Sarma.

Abstract
The larvae of some amphibian species grow and develop more slowly at lower temperature and attain larger body size at the end of metamorphosis, but this is not true for all amphibians. We have for the first time provided empirical data by using a combination of field and lab-based studies with a robust sample size (360 adults, 1000 tadpoles) for Hazara Torrent Frog (Allopaa hazarensis) and Murree Hills Frog (Nanorana vicina). In this study, we examined how tadpoles responded to different temperatures through metamorphosis, body size, developmental complications or deformities, fitness and survival. We found that the tadpoles of A. hazarensis and N. vicina showed the same response to elevated temperatures under laboratory conditions including faster metamorphosis, reduction in the body size, more frequent developmental complications or deformities such as edema and tail kinks, lower fitness and higher mortality at elevated temperatures (>26 °C). The comparison of thermal sensitivity between the two species showed that N. vicina was more sensitive to higher temperatures. Pakistan has been experiencing changes in climatic patterns, and the ecosystems in northern Pakistan are losing biodiversity due to increasing temperature, frequency of drought and intensity of floods. It is feared that these frogs may experience local extinction in future. Our findings contribute to filling the information gap regarding impacts of temperature increase on biodiversity of high altitude forested montane ecosystems and is an important contribution to future studies associating biodiversity and climate change.

Abstract
Sinus histiocytosis with massive lymphadenopathy also known as Rosai-Dorfman disease is a rare benign disease that typically manifests as lymphadenopathy with or without systemic manifestations whose etiology remains poorly understood. Most common clinical presentation is painless bilateral cervical lymphadenopathy. However, it also can present in various extranodal sites and can easily be missed because of its rarity if not considered in the differential diagnosis. It commonly occurs in children and young adults with a slightly male predominance. Clinically patients may be mistaken for lymphoma and other infectious disorders like tuberculosis especially in developing countries like in Pakistan where tuberculosis is more prevalent. Here we report a case of a 38-years-old gentleman with bilateral cervical lymphadenopathy and worsening ascites. His symptoms initially mimicking tuberculosis and lymphoma, was finally diagnosed as having Rosai-Dorfman's Disease on intra abdominal lymph node biopsy.
