Filter by:Human milk oligosaccharides (HMOs) are the third-most abundant component in mothers' milk and are an important prebiotic factor for the development of the gut microbiota of infants, promoting the growth of certain beneficial bacterial strains and providing protection against many bacterial and viral infections. HMOs induce immunomodulatory activity by affecting immune cell populations and functions. In a simulator of the adult human intestinal microbial ecosystem, fermentation of HMOs led to an increase of bifidobacteria in parallel with an increase in short-chain fatty acids as well as a reduction in inflammation markers, supporting the potential of HMOs to provide health benefits also in adults. Long-term stay in microgravity induces many physiological responses, including diminished immune function and impaired glucose tolerance which may lead to rather severe consequences. Similarly, hypoxia conditions as in the Concordia station, affects the immune system and may lead to impaired glucose tolerance and insulin resistance. The hypothesis is that HMOs as a prebiotic supplement will mitigate changes in immune function, glucose tolerance, lipid homeostasis, and neurotransmitter production. It is expected that HMO supplementation will - Modulate gut microbiota composition and function - Improve inflammation status - Improve immune function - Improve glucose tolerance - Improve nutritional status - Prevent changes in neurotransmitters associated with anxiety and depression. During the stay in Antarctica an HMO blend will be supplemented to the verum group of volunteers. The control group will receive a placebo. Experiment days with blood drawing, an oral glucose tolerance test, saliva sampling, and feces samples are planned once before, about every second month in Concordia, and once after return.
Cerebrovascular accident makes adults lose the ability to be independent in daily life, and a higher proportion of them will suffer from dysphagia. Previous studies pointed out that the tongue muscle strength of stroke patients is significantly lower than that of healthy adults. Furthermore, the tongue strength of stroke patients with dysphagia is significantly lower than those without dysphagia. Many studies investigated the performance of tongue function in healthy adults or groups with dysphagia caused by different diseases. However, the current research on the performance of tongue function in healthy adults and stroke patients in Taiwan is relatively lacking. Therefore, our purpose of this study is to investigate the performance and differences of tongue function between healthy adults and strokes patients in Taiwan. This study is expected to recruit 32 healthy adults and stroke patients in each group. The two groups will be matched with each other by gender and age (±2 years). In the study, Mann assessment of swallowing ability (MASA) will be used as an assessment tool to distinguish whether the subjects are accompany with dysphagia and the severity of dysphagia. And using Iowa Oral Performance Instrument (IOPI) to measure the value of tongue pressure. Then, analyze whether there are significant differences and the correlations. To provide clinicians with empirical data for early detection and intervention of swallowing.
The purpose of this research study is to find out more about the drug treprostinil via inhaler and the mechanisms of why patients with pulmonary arterial hypertension related to Interstitial Lung disease (PAH-ILD) have limitations during exercise. The investigator is studying treprostinil's effect on patients with PAH-ILD during exercise and its effect on their quality of life after using it for 3 months.
