We compared Boehringer Mannheim's enzymatic kit for the continuous-flow (AutoAnalyzer II) determination of serum cholesterol with Technicon's N-24a extraction method. Results for patients' samples analyzed by the enzymatic method were higher than those by the comparison method. To evaluate accuracy in the cholesterol determinations, we enrolled the enzymatic method into the Center for Disease Control's (CDC) Lipid Standardization program. We calibrated the method by use of a pooled sera for which cholesterol content was assigned by CDC after analysis by their reference Abell-Kendall procedure. We discuss the difficulties with available calibration material and limitations in the application of some commercial control materials to the enzymatic cholesterol method. The continuous-flow variables, Michaelis-Menton constants, percent ester-hydrolase activity, and other factors affecting the performance of the enzyme-linked cholesterol method are evaluated. We believe pooled sera with an assigned value for cholesterol content is the best calibrator material.

Prevalence of Transaminitis and Metabolic Dysfunction-Associated Steatotic Liver Disease Among Young Indian Adults-A Population-Based Study.
J Clin Exp Hepatol

Health Services Department, Govt of Kerala, Thiruvananthapuram, India.
Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) with onset in youth may be more consequential for adverse outcomes than that detected later in adulthood. Transaminitis in the general population is a marker of the prevalence of MASLD. There are no previous community-based studies in Indian youth assessing the prevalence of transaminitis.

Introduction: HIV-1 exploits dendritic cells (DCs) to spread throughout the body via specific recognition of gangliosides present on the viral envelope by the CD169/Siglec-1 membrane receptor. This interaction triggers the internalization of HIV-1 within a structure known as the sac-like compartment. While the mechanism underlying sac-like compartment formation remains elusive, prior research indicates that the process is clathrin-independent and cell membrane cholesterol-dependent and involves transient disruption of cortical actin.

Objectives: Dyslipidemias are major risk factors for cardiovascular disease, and other comorbidities. The focus on food and nutrition to prevent and treat cardiovascular risk factors including dyslipidemia is a paradigm shift. This is the first meta-analysis to assess the association of dates fruit and dyslipidemia in Type-2 diabetes.

Objective: To explore the effect of seeds powder { 500 mg} capsule in diabetes Type-2 (T2DM) patients in Karachi.
Methods: A randomized selection of 40 T2DM patients from Sindh Government Hospital New Karachi with their consents was done for a non-blinded controlled trial from October to December 2019 and divided into P (Positive Control, metformin 500 mg) & T (Test, + was also included, using the same dosage of CapCASP on twenty healthy volunteers. The data were analyzed using an online graph pad student's t-test and a one-way ANOVA (SPSS version 24) metformin 500mg each).
Background: Prior research linking myosteatosis with cognition in older adults has been conducted in relatively homogenous populations with narrow age ranges. We evaluated if abdominal myosteatosis was associated with processing speed in a multiethnic cohort of middle aged and older adults.
Methods: The analytical sample included 1,268 adults (46-86 years old, mean 63±9 years, 53% female of 41% White, 20% Black, 14% Chinese, and 25% Hispanic), a subset from the Multi-Ethnic Study of Atherosclerosis (MESA).
