This review examines how visual information enhances speech perception in individuals with hearing loss, focusing on the impact of age, linguistic stimuli, and specific hearing loss factors on the effectiveness of audiovisual (AV) integration. While existing studies offer varied and sometimes conflicting findings regarding the use of visual cues, our analysis shows that these key factors can distinctly shape AV speech perception outcomes. For instance, younger individuals and those who receive early intervention tend to benefit more from visual cues, particularly when linguistic complexity is lower.

Obesity is swiftly becoming a global epidemic, leading to numerous metabolic disorders and substantial socio-economic burdens. Investigating natural bioactive compounds is crucial to support the use of traditional anti-obesity medications while mitigating the adverse effects. This study posited that a combination of and (Meratrim) could prevent fat accumulation in obese mice.

This study investigated the effects of black bean (BB) supplementation on the growth performance, lipid metabolism, and antioxidant capacity of high-fat diet-induced obese mice. The results demonstrated that although the inclusion of BBs led to increased body weight, total energy intake, and feed efficiency ratio, it did not significantly alter the overall body composition, including adiposity. Notably, BB consumption reduced total cholesterol levels, suggesting its potential to manage dyslipidemia and reduce the risk of atherosclerotic cardiovascular diseases.

Unlabelled: Excessive hepatic lipid accumulation is closely linked to inflammation, insulin resistance, and metabolic syndromes. We hypothesized that a combined extract containing (SCE) could alleviate hepatic lipid accumulation. Male Sprague-Dawley rats fed a high-sucrose diet (HSD) were randomly assigned to three groups (n = 6): normal diet (ND), HSD (60% kcal from sucrose), and HSD + SCE (HSD with 2.

As the world becomes a super-aged society, cognitive decline is public health problems that are increasing rapidly. A healthy diet has great potential for maintaining cognitive health. A diet that could delay the onset of neurodegenerative diseases has been developed: the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, a hybrid form of the Mediterranean diet and the Dietary Approaches to Stop Hypertension (DASH) diet.

Sarcopenic obesity, low muscle mass, and high body fat are growing health concerns in the aging population. This review highlights the need for standardized criteria and explores nutraceuticals as potential therapeutic agents. Sarcopenic obesity is associated with insulin resistance, inflammation, hormonal changes, and reduced physical activity.

Extracellular vesicles (EVs), which are heterogeneous membrane-based vesicles with bilayer cell membrane structures, could be versatile biomarkers for the identification of diverse diseases including cancers. With this potential, this study has attempted the Raman spectroscopic identification of gall bladder (GB) cancer by directly measuring the EV solution extracted from human bile without further sample drying. For this purpose, bile samples were obtained from four normal individuals and 21 GB polyp, eight hepatocellular carcinoma (HCC), and five GB cancer patients, and EVs were extracted from each of the bile samples.

Article Synopsis
  • The study investigates the link between how soon a smoker has their first cigarette after waking and the risk of developing obstructive respiratory issues, such as chronic obstructive pulmonary disease (COPD).
  • Researchers analyzed data from 392 current smokers, distinguishing those who smoked within 30 minutes of waking (early group) from those who waited longer (late group).
  • Findings showed that smokers who had their first cigarette within 30 minutes had over twice the risk of obstructive pulmonary impairment compared to those who waited longer, suggesting this timing could be a key factor in assessing risk for respiratory diseases.

Vaccines play a key role in the prevention of illness in the elderly, are cost effective, and generally safe. Hepatitis C, cirrhosis, autoimmune hepatitis, and inflammatory bowel disease are more prevalent than ever among older adults. Along with an age-related decline in immune system function (immunosenescence), these diseases make elderly individuals more susceptible to infections and more likely to experience a poor outcome relative to their younger counterparts.
