This research explores the flow penetration in porous media by virtue of capillary action and geometric control of the liquid imbibition rate in microfluidic paper-based analytical devices (μPADs) having applications in food quality management, medical diagnostics, and environmental monitoring. We examine changes in flow resistance and membrane geometry, aiming to understand factors influencing capillary penetration rates for various practical applications. We conducted experiments and simulations using lateral porous membranes and altered the flow resistance by changing the liquids or the paper channel geometry by adding cavities.

Objective: Cervical cancer is one of the most destructive diseases among females worldwide, especially in developing countries. Interleukin-10 (IL10) is a multifunctional cytokine, and polymorphisms in the IL10 gene have been identified in multiple malignancies. However, no prior studies were conducted to determine the association of IL10 polymorphisms (rs1800872 and rs1800896) with cervical cancer patients in Bangladesh.

Methods: This cross-sectional study of correlational survey was conducted at Services Institute of Medical Sciences in September 2019, involving students of final professional year who filled a proforma to rate their bedside teaching experience during clinical rotations using rating scale. Mean scores of items were determined with score < 3 reflecting dis-satisfaction.
Objective: To determine efficacy of diclofenac suppository in reducing post-ERCP pancreatitis (PEP) and identify risk factors for PEP.
Methods: This is a placebo-based prospective study at Department of Medicine & Gastroenterology, Services Institute of Medical Sciences / Services Hospital, Lahore performed from January 2018 to June 2019. Patients were randomized to receive diclofenac suppository or glycerine suppository before ERCP.
Objective: To compare efficacy of high vs low dose rifaximin for primary prophylaxis of portosystemic encephalopathy (PSE) in decompensated liver cirrhosis.
Methods: In a quasi-experimental double blind randomized study at Services Institute of Medical Sciences (SIMS), Lahore from August 2017 to August 2018, patients of decompensated cirrhosis with no previous PSE were randomized to receive twice daily rifaximin 200mg in Group-A and 550mg in Group-B. Patients were followed for 6 months for development of PSE.

Objective: To determine real-world effect of adding daclatasvir (DCV) to chronic hepatitis C treatment by comparing sustained viral response of sofosbuvir (SOF)/DCV±ribavirin (RBV) and SOF+RBV combination in patients with genotype 3 hepatitis C.
Patients And Methods: Patients with chronic hepatitis C, genotype 3, presenting at the DHMC Hepatology Clinic from October 2014 till March 2018 were treated initially with 6 months of SOF/RBV, and once DCV was available, with SOF/DCV±RBV for 3 or 6 months. Negative hepatitis C virus RNA by PCR, sustained viral response 12 weeks after treatment (SVR12), was the primary end point for per-protocol analysis.
Objective: To determine health related quality of life (HRQOL) of medical students and its correlation with their academic performance.
Methods: Cross sectional study at Services Institute of Medical Sciences, included students of 4 and final year MBBS, who filled SF-36 proforma of HRQOL. Scores of 8-domains and of physical component and mental component summary were determined.
Objective: To determine 3 generation cephalosporin resistance in patients with community-acquired spontaneous bacterial peritonitis (SBP) using early response assessment.
Methods: This prospective quasi-experimental study was carried out at Doctors Hospital & Medical Center from January 2016 to September 2018. Patients with cirrhosis and SBP were included.
Objective: To compare sustained viral response to sofosbuvir/ribavirin ±interferon therapy in patients of hepatitis C with and without liver cirrhosis.
Methods: This observational study of chronic hepatitis C patients was carried out at Doctors Hospital and Medical Center (DH&MC). After diagnostic workup, Sofosbuvir/ribavirin for 24 weeks or sofosbuvir/ribavirin/pegylated interferon for 12 weeks were prescribed.
Objective: To compare environmental perception as measured by the Dundee Ready Educational Environment Measure of students with high and low academic performance.
Methods: This cross-sectional analytical study was carried out at the Gujranwala Medical College, Gujranwala, Pakistan, and comprised medical students.
