Article Synopsis
  • The study investigated how vascular function differs in healthy men with a family history of hypertension compared to those without, focusing on the impact of sugar intake.
  • Researchers measured blood flow and resistance after giving participants varying doses of sugar (sucrose) to observe acute effects on vascular health.
  • Results showed that men with hypertensive parents had significantly poorer vascular function and their blood flow decreased further after consuming sugar, suggesting they should limit sugar intake.

Background: During the COVID-19 pandemic, pre-clerkship medical education, including all physiology classes, was obliged to change to online teaching due to limitations of on-site (face-to-face) classes. However, the effectiveness of online teaching in non-lecture physiology topics during the COVID-19 pandemic has not been thoroughly investigated.

Method: We conducted a prospective study to evaluate the students' academic achievement and opinions on online teaching during the COVID-19 academic year.

Background: Pre-clerkship medical curriculums consist of a series of organ system-based courses and lectures but often lack an integration between organ systems. Such integration could be beneficial for clerkship years and students' future career. Hence, we aimed to share our process of organising an integrative teaching approach in a large class of pre-clerkship medical students and to reflect the students' perspective toward the teaching process in this observational study.

Article Synopsis
  • The study investigates the impact of an intradialytic exercise (IDX) program on physical activity and health outcomes in dialysis patients undergoing high-volume online hemodiafiltration (OL-HDF).
  • Results showed that patients in the IDX group significantly increased their daily physical activity by over 1,000 steps per day compared to a decrease in the control group, although physical fitness and quality of life remained unchanged.
  • The IDX group also exhibited improved metabolic parameters, including higher serum albumin and better hemoglobin levels, while preserving lean body mass and achieving greater phosphate reduction compared to the control group.

Article Synopsis
  • The study investigates the effects of the Ala54Thr mutation in the FABP2 gene on glucose regulation and lipid metabolism in sedentary, nondiabetic individuals on a low-fat diet.
  • It finds that carriers of the Thr54 variant exhibit lower glucose tolerance, higher fasting glucose levels, and reduced insulin sensitivity compared to individuals with the Ala54 variant.
  • Additionally, Thr54 carriers showed increased lipid oxidation rates, suggesting a potential link between this mutation and glucoregulatory dysfunction.

Article Synopsis
  • - Endurance exercise training enhances fibrinolysis, but the benefits may vary between men and women, particularly in relation to body composition and lipid levels.
  • - In a study of overweight to obese individuals aged 50-75, exercise training lowered tissue plasminogen activator (t-PA) antigen and plasminogen activator inhibitor-1 (PAI-1) activity notably more in men than in women.
  • - The improvements in fibrinolytic markers were similar for both genders regarding t-PA activity, but in men, reductions in abdominal fat correlated strongly with fibrinolytic changes, indicating a stronger link between abdominal obesity and training effects in men.

The present study sought to investigate, in sedentary men and women, (a) whether a common functional gene variant (peroxisome proliferator-activated receptor-gamma2 [PPARgamma2] Pro12Ala) predicts insulin action and (b) whether improvements in insulin action in response to endurance exercise training are associated with PPARgamma2 Pro12Ala. Sedentary, 50- to 75-year-old men and women (N = 73) were genotyped and underwent oral glucose tolerance tests (OGTTs) before and after 6 months of endurance training. At baseline, men heterozygous for the Pro12Ala variant had a greater OGTT insulin area under the curve (AUC) as compared with Pro12 homozygous men (P = .

  • A polymorphism in the IL-6 gene linked to diabetes and insulin resistance was studied in sedentary older adults undergoing aerobic exercise training.
  • The study involved 87 participants, with differences noted in fasting glucose levels based on the IL-6 genotype, particularly between the CC and GG groups.
  • Results showed that only the GG genotype group experienced significant improvements in glucose tolerance, indicating that the IL-6 gene polymorphism may influence how individuals respond to exercise training in terms of glucose metabolism.*

Purpose: Impaired endogenous fibrinolysis is an important predictor for increased risk of stroke and myocardial infarction. Acute exercise can enhance fibrinolysis, primarily by stimulating short-term increases in plasma tissue plasminogen activator (tPA), which is postulated to protect against atherothrombotic events. No prior studies have examined the fibrinolytic response to exercise in stroke survivors despite their high risk for recurrent stroke and myocardial infarction.
