Objective: Aim: Testing Cordia myxa extract on colon cancer cell line and caspase-3 gene and COX-2 protein expression.
Patients And Methods: Materials and Methods: This study used Cordia myxa ethanolic extract at various dosages on SW480 cells. Cell proliferation was measured using MTT, also examined effect of Cordia myxa extract on caspase-3 gene expression using quantitative real-time polymerase chain reaction.
Objectives: To explore the relationship, if any, of gestational diabetes mellitus with maternal age, body mass index, serum tenascin-C and homeostatic model assessment for insulin resistance, and to see if these could act as predictive markers for gestational diabetes mellitus.
Methods: The case-control study was conducted from February to August 2022 at the outpatient department of gynaecology and obstetrics at the Civil Hospital, Karachi, and comprised pregnant females aged 18-40 years having gestational age 20-34 weeks. After noting down baseline characteristics and anthropometric measurements, the participants were subjected to oral glucose tolerance test on the basis of which they were divided into three groups; pregnant healthy controls in group 1, those with gestational diabetes mellitus on diet control in group 2, and those with gestational diabetes mellitus taking medicines for the condition in group 3.
Given the emergence of the SARS-CoV-2 Omicron BA.1 and BA.2 variants and the roll-out of booster COVID-19 vaccination, evidence is needed on protection conferred by primary vaccination, booster vaccination and previous SARS-CoV-2 infection by variant.

This unexplained benefit has sparked the debate on potential additional pleiotropic effects of ASGR1 variants. Since ASGR1 has also been implicated in platelet homeostasis, we evaluated platelet function in heterozygous ASGR1 del12 carriers and controls.

Objective: We hypothesized that Lp(a) induces endothelial cell inflammation by rewiring endothelial metabolism.
Methods And Results: We evaluated the impact of Lp(a) on the endothelium and describe that Lp(a), through its oxidized phospholipid content, activates arterial endothelial cells, facilitating increased transendothelial migration of monocytes.
The importance of protein glycosylation in regulating lipid metabolism is becoming increasingly apparent. We set out to further investigate this by studying the effects of defective glycosylation on plasma lipids in patients with B4GALT1-CDG, caused by a mutation in B4GALT1 with defective N-linked glycosylation. We studied plasma lipids, cholesteryl ester transfer protein (CETP) glyco-isoforms with isoelectric focusing followed by a western blot and CETP activity in three known B4GALT1-CDG patients and compared them with 11 age- and gender-matched, healthy controls.

If left untreated, the yearly mortality rates increase up to 25%. Currently, no effective pharmacological interventions have been established to treat or prevent AVS.

We set out to further investigate this by studying patients with type I congenital disorders of glycosylation (CDGs) with defective N-glycosylation.
Methods: We studied 29 patients with the 2 most prevalent types of type I CDG, ALG6 (asparagine-linked glycosylation protein 6)-deficiency CDG and PMM2 (phosphomannomutase 2)-deficiency CDG, and 23 first- and second-degree relatives with a heterozygous mutation and measured plasma cholesterol levels.
Purpose Of Review: Evidence accumulates suggesting that cellular metabolic alterations fuel and dictate the inflammatory state of cells. In this review, we provide an overview of the observed metabolic reprogramming in endothelial cells and innate immune cells upon interaction with modified lipoproteins, thereby contributing to the progression of atherosclerosis.
Recent Findings: Inflammatory endothelial cells at sites exposed to disturbed flow patterns show increased glycolytic activity.
Objective: To evaluate the frequency of fetomaternal outcome of pregnancy with Mitral stenosis admitted in Civil Hospital Karachi.
Methods: It was a two years descriptive study done in the Department of Obstetrics and Gynaecology Civil Hospital Karachi. All pregnant women with a known or newly diagnosed Mitral stenosis on echocardiography were included in the study.
Background: Hepatitis C virus (HCV) is a major cause of liver cirrhosis and hepatocellular carcinoma and infects about 3% world population. Response to interferon therapy depends upon the genotype of the virus and factors associated with the host. Despite a good response to interferon therapy, a considerable number of genotype 3a infected patients remains unalleviated.

Genetic components of disease etiology, especially human leukocyte antigen (HLA) associations, are well known. Ethnic differences account for a number of variations in disease association with the HLA locus and there seem to be differences in various studies regarding its genetic predisposition.
View Article and Find Full Text PDFBackground: A recently discovered occult HCV entity reported by various investigators seems to be highly controversial. Especially, the clinical significance of these findings remains uncertain. For optimal outcome of antiviral therapy, investigation of occult HCV needs a broad-based probe in order to investigate the results of viral therapy and its host/viral interaction.
View Article and Find Full Text PDFHepatitis C virus (HCV) infection is prevalent throughout the world and interferon (IFN)-based treatments are currently the only therapeutic option. However, depending upon variations in their human leukocyte antigen (HLA), some patients do not respond well to IFN therapy. The current study evaluated the HLA allele and haplotype distribution of 204 HCV-seropositive individuals from Islamabad, Pakistan, who were receiving standard IFN therapy.

Polymorphism at C677T shows marked heterogeneity based upon ethnicity and geographical location. Pakistani population consists of various ethnic groups confined to different regions of the country where congenital and genetic defects are a major health concern.
