Acute effects of tai chi exercise on cardiac autonomic function in healthy adults with tai chi experience.

About 1 in 3 American adults have cardiovascular disease associated with risk factors such as physical inactivity, obesity, and stress. Heart rate variability (HRV) analysis is considered a non-invasive procedure for analyzing cardiovascular autonomic influence. Depressed HRV has been linked to abnormal cardiovascular autonomic modulation.

Balance improvements after a week-long tai chi workshop as determined by dynamic posturography - biomed 2010.

The purpose of this study was threefold: 1) to explore static and dynamic posturography as an objective measure of balance performance after intensive practice of Tai Chi; 2) to determine whether multi-day Tai Chi workshops are viable venues to gather data from long-term Tai Chi practitioners and 3) to determine whether a 6-day, intensive Tai Chi intervention would improve the balance of participants. For posturography measurements we used the CAPS Professional System (Vestibular Technologies, Cheyenne, WY), a portable computerized device which monitors body sway for 20 seconds, with eyes open or closed, when standing on a hard (static) or unstable (dynamic) surface. We employed the system to test 54 participants in a 6-day.

Annexin 7-immunoreactive microglia in the hippocampus of control and adrenalectomized rats.

Annexin 7 (ANX7), also termed synexin, is a member of the annexin family of calcium-binding proteins. In the present study, we examined the distribution and cellular localization of ANX7-immunoreactivity in the rat hippocampus and its response to adrenalectomy (ADX). ANX7 was co-localized with OX42 in microglia distributed throughout the hippocampus of both control and ADX animals.

Annexin 6 immunoreactivity in select cell populations in the rat brain.

We examined the distribution of annexin 6 (ANX6) in rat brain with immunohistochemistry (IHC). Several neuronal cell populations were intensely labeled with the ANX6 monoclonal antibody (MAb), including layer 5 of neocortex, the lateral septum, the lateral hypothalamic area, the red nucleus, and the Purkinje cell layer in cerebellum. Neuronal immunolabeling was localized to the nucleus and the cytosol.
