BDNF Val66Met polymorphism alters sympathovagal balance in healthy subjects

Yang AC, Chen TJ, Tsai SJ, Hong CJ, Kuo CH, Yang CH, Kao KP

American journal of medical genetics. Part B, Neuropsychiatric genetics : the official publication of the International Society of Psychiatric Genetics, 153B(5): 1024-30

These results suggest that an altered sympathovagal balance with relatively decreased parasympathetic activity is associated with the Met/Met genotype, suggesting a potential role for the studied BDNF polymorphism in modulating cardiac autonomic functions.

Heart rate variability in psychiatric disorders

Yang AC, et al.

Taiwanese Journal of Psychiatry, 24(2): 99-109

A review introducing the principles and techniques of heart rate variability (HRV) analysis and illustrating how autonomic nervous system dysregulation, measured by HRV, is associated with psychopathology and cardiovascular comorbidity in psychiatric disorders.

Profiling objective sleep quality in a healthy Taiwanese sample using a novel electrocardiogram-based cardiopulmonary coupling analysis

Yang AC, et al.

Taiwanese Journal of Psychiatry, 24(3): 201-211

Using a validated electrocardiogram-based cardiopulmonary coupling (CPC) analysis in 155 healthy Taiwanese subjects, this study profiles how age and gender affect sleep-related cardiovascular and respiratory dynamics, establishing normative objective sleep-quality references.

Genomic classification using an information-based similarity index: application to the SARS coronavirus

Yang AC, Goldberger AL, Peng CK

Journal of computational biology : a journal of computational molecular cell biology, 12(8): 1103-16

The information based similarity index provides a new tool to measure the similarity between datasets based on their information content and may have a wide range of applications in the large-scale analysis of genomic databases.
