Sex Differences In Insulin Resistance And Triglyceride/Hdl-Cholesterol Ratio In Human Subjects, Jiyoon Jung, Lakshman Segar, Christine Whitehair, James Bailey, Ashley Coleman, George Scott

Rowan-Virtua Research Day

Background: Insulin resistance (IR) plays a major role in dyslipidemia and the associated cardiovascular disease risk. To date, it remains unclear as to how IR alters plasma lipid profile in males versus females. The present study is an initial step to determine sex-specific differences in IR and plasma lipid profile using 40 μL of capillary blood. Methods: 19 adults aged 30-64 were recruited from Rowan Medicine-Sewell clinics, with 13 participants (9 males, 4 females) consenting to the study. After collecting 40 μL of capillary blood via finger prick, the samples were analyzed for glucose, triglyceride (TG), and HDL-cholesterol (HDL-C) using …

Nyarko, Enoch Odame Anto, William Kwame Boakye Ansah Owiredu

Research outputs 2022 to 2026

Aim To characterize clinically relevant subgroups of patients with type-2 diabetes mellitus (T2DM) based on adiposity, insulin secretion, and resistance indices. Methods A cross-sectional study was conducted at Eastern Regional Hospital in Ghana from July to October 2021 to investigate long-term patients with T2DM. To select participants, a systematic random sampling method was employed. Demographic data was collected using a structured questionnaire and fasting blood samples were taken to measure glycemic and lipid levels. Blood pressure and adiposity indices were measured during recruitment. The risk of cardiovascular disease (CVD) was defined using Framingham scores and standard low-density lipoprotein thresholds. To …

The Effect Of Fructose Metabolism On Hepatic De Novo Lipogenesis And Adipose Tissue Insulin Resistance, Taghreed Ibrahim Fadhul

Theses and Dissertations--Nutritional Sciences

There is a worldwide epidemic of obesity and metabolic dysfunction. The root cause of obesity is driven by a positive energy balance, which is a consequence of increased caloric intake and decreased energy expenditure. Energy intake is the more dominant force, as increasing energy expenditure is a time-consuming and labor-intensive process. The caloric surplus can be mainly accounted for by increased consumption of high-fat and high-sugar diets. While the risks associated with fat consumption are well-documented, the impact of sugar intake is less understood.

Fructose is a simple sugar widely consumed in modern diets. Its intake has been associated with …

The Enzymatic Regulation Of Contraction-Induced Toll-Like Receptor 4 Shedding From C2c12 Myotubes, Rebekah C. Gridley

Health, Exercise, and Sports Sciences ETDs

Stimulated contractions are shown to increase toll-like receptor 4 (TLR4) release from C2C12 myotubes in vitro. The purpose of this study was to determine if the release of TLR4 from myotubes is controlled by proteolytic membrane cleavage. A broad-spectrum metalloprotease inhibitor was used to test this hypothesis in a C2C12 cell culture model, and TLR4 concentrations in the cell culture supernatant were measured via enzyme-linked immunosorbent assay (ELISA) following stimulated myotube contractions.

ELISA analysis revealed TLR4 concentrations below the sensitivity threshold of the ELISA kit for all experimental conditions. In confirming the effectiveness of the electrical pulse stimulation (EPS) treatment, …

The Effects Of Sglt2 Inhibitors In Patients With Metabolic Dysfunction-Associated Fatty Liver Disease; A Narrative Review, Mihaela Simona Popoviciu, Lorena Paduraru, Mominur Rahman, Fatema Akter Supti, Roxana Adriana Stoica, Delia Reurean Pintilei, Cristina Ioana Bica, Simona Cavalu

Journal of Mind and Medical Sciences

Worldwide, metabolic dysfunction-associated fatty liver disease (MAFLD) is a significant public health concern, especially since more than fifty percent of people with type 2 diabetes are affected by it. This pathological condition includes all states of fatty liver disease, from non-alcoholic fatty liver disease (NAFLD) to steatohepatitis (NASH). Prolonged evolutions can lead to cirrhosis and cancer, so treatment must be started early. Hepatic steatosis may be improved by sodium glucose co-transporter 2 inhibitors (SGLT2 inhibitors), which prevent glucose reabsorption in the proximal renal tubule and increase urinary excretion, thus lowering plasma glucose levels. Experimental studies in animal models have suggested …

The Function Of The Insulin Receptor In Liver Subcell Types And Its Dichotomous Role In Hepatic Dysfunction, Wang-Hsin Lee

Theses and Dissertations--Pharmacology and Nutritional Sciences

Insulin resistance and metabolic dysfunction-associated steatotic liver disease (MASLD) have become significant health issues worldwide. Increased prevalence of hepatic insulin resistance and MASLD worsens the threat of its progressive complications, such as liver fibrosis, which can lead to cirrhosis and death if left untreated. Treatments for MASLD-induced liver fibrosis are mainly insulin sensitizers. However, activating insulin signaling leads to a higher death rate in end-stage liver fibrosis. This dissertation discusses the emerging insights into hepatic insulin resistance and potential treatment targets in the heme degradation pathway for reversal. We also investigated the mechanisms that the insulin receptor (INSR) regulates in …

Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino

Graduate Theses/Dissertations

Recent insights into the pathological role of Nucleotide P2Y₂ receptor suggest P2Y₂R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y₂R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y₂R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y₂ in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological …

Background. Metabolic syndrome (MetS) represents a clustering of metabolic risk factors for cardiovascular disease. Many studies have shown the influence of an unhealthy lifestyle on the risk of MetS, yet some aspects remain controversial. Aim of the study: to investigate the relationship between an unhealthy lifestyle and the risk of MetS.

Materials and Methods. The study was conducted using a sample of 181 patients, 54 (29.8%) males and 127 (70.2%) females, aged 59.95±10.8 years. The baseline survey involved the completion of structured questionnaires and clinical examination.

Results. Rural environment, lower education level, past smoking, the absence of fruit/vegetables in the …

Repurposing Diabetes Drugs To Treat Insulin Resistance In Alzheimer’S Disease‌, Yael Lazarus

The Science Journal of the Lander College of Arts and Sciences

Alzheimer’s disease is a neurodegenerative condition which results in a significant decline in cognitive status. Novel treatment approaches for Alzheimer’s are sorely needed, as current medications for the disease offer only marginal clinical benefit. Research has discovered a connection between the pathology of Alzheimer’s and Type 2 Diabetes, two serious and seemingly unrelated disorders. Clinical studies have shown that Alzheimer’s disease is associated with brain insulin resistance similar to the pathology of Type 2 Diabetes. This observation has led to the notion that drugs developed for the treatment of Type 2 Diabetes may be beneficial in modifying the cognitive function …

The Effect Of Run Sprint Interval Training On Diabetic Metabolic Markers In Prediabetic Adults, Kathryn L. Hilovsky

Masters Theses, 2010-2019

Abstract

Purpose: The primary purpose of this study was to compare the effects of an 8-week run-sprint interval training (R-SIT) and continuous moderate-intensity training (MIT) on fasting blood glucose, HbA1c, insulin sensitivity, and β-cell function in sedentary, prediabetic adults. Secondary outcomes of the study included anthropometric, body composition variables, and aerobic capacity.

Methods: Sedentary, physician diagnosed prediabetic individuals were randomized into R-SIT (n=7, BMI 36.76 ± 9.79) or MIT (n=8, BMI 40.59 ± 12.49) interventions. Subjects participated in supervised exercise three times a week and attended a Diabetes Prevention Program course, once weekly. R-SIT participants performed 4-6 x 30-second …
