OSF (Oral submucous fibrosis) is a chronic disease characterized by inflammation and progressive fibrosis of the submucosal tissues with the potential to progress into OSCC (Oral squamous cell carcinoma). Matrix metalloproteinases (MMP) are endopeptidases that play a role in extracellular matrix remodeling and pathophysiology of various diseases. The study aims to evaluate the gene polymorphism and protein expression of MMP-8 and their association with the severity of OSF.

View Article and Find Full Text PDFBackground: Pulmonary arterial hypertension (PAH) is characterized by several maladaptive mechanisms: endothelial dysfunction, oxidative stress, inflammation, pathological remodeling of the pulmonary arterioles, and cellular hypoxia. These mechanisms all favor progressive pulmonary vasculopathy and progressive right ventricle (RV) dysfunction.
Aim: This study aims to characterize the experimental model of monocrotaline-induced PAH in rats.
Background/aim: Oral cancer (OC) is the leading cause of fatalities in Pakistan among males due to inadequate oral hygiene and chewing habits. However, genetic susceptibility patterns also play a critical role in disease progression. Since the frequency of Resistin (RETN) SNP (Single nucleotide polymorphism) rs3219175 is unknown; there is a requirement for early diagnosis of the OC.

This study aimed to determine the frequency of BRAFV600E mutations in colorectal carcinoma tissue in the Pakistani population and to associate BRAFV600E expression with CD133, a marker of colorectal stem cells, and CDX2 marker of differentiation.
Methods: Sanger Sequencing of exon 15 (426 bp) including the hotspot V600E was performed on formalin-fixed-paraffin-embedded (FFPE) CRC tissue samples of 115 patients.
Purpose: This study aimed to analyze two decades of consecutive mortality data to investigate cardiovascular deaths in Systemic Lupus Erythematosus (SLE) across the United States (US), identifying patterns and disparities in mortality rates.
Methods: A retrospective analysis was conducted using mortality data from the CDC WONDER database spanning 1999-2020. ICD-10 codes for diseases of circulatory system (I00-I99) and for SLE (M32) were used to identify cardiovascular-related deaths in SLE among adults aged 25 years and older at the time of death.
This study aimed to find the association between clinical characteristics, cytogenetics, and post-induction outcomes of childhood acute lymphoblastic leukemia. The study was conducted at the Indus Hospital in Karachi. Initial total leukocyte count (TLC), cytogenetics, CNS status, and post-induction remission status were recorded.

Forming part of the management of such conditions, capsaicin as a molecule has proven effective. This review has investigated the central nervous system modifications exhibited in such conditions and the pharmacological mechanisms of capsaicin relevant to this.

Methods: An exploratory study was carried out from December 2022 to February 2023 at a public sector medical college of Rawalpindi. A purposive sampling technique was employed to collect data from all content experts of the study institute who participated in item vetting activity during pre-exam moderation in the university.
Abnormal uterine bleeding (AUB) is the most common and frequent presenting complaint in Gynaecology in all age group especially in perimenopausal and postmenopausal women. The spectrum of AUB in women of our country includes a wide varieties of organic pathology. The objective of this study was to assess the role of endometrial thickness as a predictor of endometrial malignancy among the women presenting with AUB.

Methods: hAECs were isolated by using the enzymatic digestion method and characterized for the presence of specific stem cell markers. In-vitro, hepatic differentiation of hAECs was carried out by using a combination of small molecules.
High-grade gliomas are extremely fatal tumors, marked by severe hypoxia and therapeutic resistance. Autophagy is a cellular degradative process that can be activated by hypoxia, ultimately resulting in tumor advancement and chemo-resistance. Our study aimed to examine the link between autophagy markers' expression in low-grade gliomas (LGGs) and high-grade gliomas (HGGs).

Objective: To investigate the association of alanine transaminase (ALT) with transient elastography grades to define various nonalcoholic fatty liver disease (NAFLD) groups for disease status.
Study Design: Cross-sectional, descriptive study. Place and Duration of the Study: Gastroenterology Outpatient Clinic, Ziauddin Hospital, from January to December 2022.
Objective: To investigate the role of Human Papilloma Virus (HPV) (16/18) in relation to the molecular genetic mechanisms of Cyclin D1, p53, p16, and Epidermal growth factor receptor (EGFR) in Laryngeal Squamous Cell Carcinoma (LSSC).
Methods: A cross-sectional study of 88 (Formalin-fixed Paraffin Embedded) FFPE laryngeal biopsies were done at Basic Medical Sciences Institute, Jinnah Postgraduate Centre, Karachi from 2010 to 2019 with the application of Polymerase chain reaction (PCR) for HPV 16/18and Immuno-histochemical staining for molecular genetic expression of proteins, Cyclin D1, p53, p16, and EGFR.
Results: Out of 88 cases of Laryngeal Squamous Cell Carcinoma (LSSC) there was female preponderance.
When a baby dies in utero, the options are either to wait for spontaneous labour or to induce it. An obstetrician, encounters with a perplexity of choosing a management plan when this worst situation of IUFD coalesced by history of previous caesarean delivery. The ideal drug for the termination should not only be efficacious and cost-effective, but also be convenient enough to avoid operative interference arising from a wasted pregnancy.
