BH4 improves postprandial endothelial function following a high-fat meal in man and post-menopausal women.

Shah, Y, L. Bass; G.W. Davison; N. Seigler; J.S. Pollock; J. Thomas; R.A. Harris.

Objective.  The timing and duration of menopause is important when evaluating the risk for cardiovascular disease (CVD) in postmenopausal women, likely related in part to nitric oxide (NO) bioavailability.  The flow mediated dilation (FMD) test is a non-invasive assessment of NO bioavailability in humans, and tetrahydrobiopterin (BH4) is essential for NO synthesis.  A high-fat meal (HFM) has been used to increase lipemia and reduce NO-bioavailability.  Thus, this study sought to determine if menopausal transition has any impact on the postprandial endothelial function response to a HFM and evaluate the effect of BH4 on postprandial endothelial function in postmenopausal women and men. Conclusions.  Co-ingestion of BH4 with a HFM not only alters the sex-steroid hormone ratio, it improves postprandial FMD following a HFM regardless of postmenopausal status or sex.

How lateral inhibition and fast retinogeniculo-cortical oscillations create vision: A new hypothesis.

Ravinder Jerath; Shannon M. Cearley; Vernon A. Barnes, Elizabeth Nixon-Shapiro.

Objective: The role of the physiological processes involved in human vision escapes clarification in current literature. Many unanswered questions about vision include: 1) whether there is more to lateral inhibition than previously proposed, 2) the role of the discs in rods and cones, 3) how inverted images on the retina are converted to erect images for visual perception, 4) what portion of the image formed on the retina is actually processed in the brain, 5) the reason we have an after-image with antagonistic colors, and 6) how we remember space. This theoretical article attempts to clarify some of the physiological processes involved with human vision. Conclusion: Our theory suggests image inversion never takes place on the retina, but rather images fall onto the retina as compressed and coiled, then amplified through lateral inhibition through intensification and amplification on the OFF-center cones. The intensified and amplified images are decompressed and expanded in the brain, which become the images we perceive as external vision.
