Abstract

Background Nonalcoholic fatty liver disease (NAFLD) is one of the most widespread chronic liver diseases, caused by the development of insulin resistance. One of the mechanisms involved is a disturbance in insulin signaling by certain toxic substances that interact with one of the proteins responsible for the insulin signaling pathway. Increased homocysteine level, upon disruption of the methionine pathway, is associated with insulin resistance. The aim of this study was to evaluate the effect of hyperhomocysteinemia and insulin resistance (HOMA-IR level) induced by dietary vitamin B12 restriction on liver steatosis. Methods A study of laboratory experimental design was conducted involving 18 male Sprague Dawley rats (age 36-40 weeks, BW 300-350 g), that were randomly divided into 3 groups: control, 8-week treatment, and 16-week treatment. Standard AIN-93 diet was administered to the control group, whereas rats in the treatment groups were fed vitamin B12 deficiency-AIN-93M. At the end of treatment, liver homocysteine levels were determined by ELISA, HOMA-IR values were calculated, and steatosis degree of the liver was determined histologically. Statistical analysis was performed using independent t-test. Results A significant increase in liver homocysteine levels was found between the control and both the 8- and 16-week treatment groups (p<0.001). HOMA-IR levels were significantly higher in both treatment groups compared to controls (p<0.001). The area of liver steatosis in both treatment groups was significantly larger than that of the control group (p<0.001). Conclusion Increased homocysteine levels due to dietary vitamin B12 deficiency induces liver steatosis due to insulin resistance in rats.

Abstract

BackgroundCognitive impairment and dementia are some of the major health concerns in the aging population. Many studies showed positive effects of physical exercise in delaying or preventing these conditions. Brain Gym ® exercises is a structured aerobic exercise involving head, eyes and crossing movements of the extremities in order to stimulate both brain hemispheres. This study was conducted to evaluate the effect of Brain Gym ® exercises sessions on cognitive function and plasma brain-derived neurotrophic factor (BDNF) in the elderly.MethodsA non-blinded randomized controlled study involving 64 healthy women aged >60 years who were randomized into Brain Gym ® exercises treatment group (n=32) and control group (n=32). Treatment group joined 60 minutes of brain gym exercises sessions twice a week for 12 weeks. The measured outcomes were cognitive function (assessed by mini-mental state examination [MMSE] questionnaire) and plasma BDNF levels. The outcomes were measured at base-line and after the intervention. An independent t-test was used to analyze the data.ResultsThe BDNF levels were increased in both groups after 12 weeks, and there was a significant difference between treatment group (41.26 ± 6,82 ng/mL) and control group (37.10 ± 8.11 ng/mL)(p=0.040). However, the MMSE score was not significantly different between the two groups (p=0.200).ConclusionBrain Gym ® exercises sessions significantly increase plasma BDNF level in the elderly population. In practical terms, we may suggest evaluation of the effects of Brain Gym ® exercises as a strategy in the treatment of disorders associated with central degenerative changes.

Abstract

BackgroundPulmonary function decreases with age. Similarly, physical exercise capacity measured by maximal oxygen uptake, which is one indicator to measure the level of cardiac and pulmonary vascular resistance, decreases by >1% per year. This results in many respiratory diseases that occur in older persons, especially in obese older persons. Pulmonary function is a basic component of cardiopulmonary endurance, besides other factors such as age, hemodynamics, metabolism, and lifestyle. The objective of this study was to determine whether body mass index (BMI) and pulmonary function have a significant association with cardiopulmonary endurance in older women. MethodsThe study used a cross-sectional design involving 66 subjects aged 60 years and older in South Jakarta. Data was collected by measuring body mass index (BMI), pulmonary function (FEV1, FVC, FEV1/FVC) and maximal oxygen uptake (VO2 max) for cardiopulmonary endurance. Data analysis used simple and multiple linear regression tests in SPSS v.25, with p<0.05. ResultsOf the 66 older persons, 57.6% was obese. Pulmonary function of subjects showed restriction (33.3%), obstruction (6.1%) and a combination of restriction and obstruction (1.5%). Furthermore, mean VO2 max was 12.2 mL/kg/min. Multiple linear regression analysis showed a significant association of BMI and FEV1/FVC with VO2 max (â =-0.56; 95% CI=-0.81 - (-) 0.31; p=0.000; â =0.09; 95% CI=0.01-0.18; p=0.028). BMI was the most influential risk factor of VO2 max (Beta = -0.46). ConclusionsThere was a significant association of BMI and FEV1/FVC with VO2 max, BMI being the most influential risk factor of cardiopulmonary endurance in older women.
