Eat yourself young: Anti-aging dietary compounds

We frequently hear reports in the press about “super foods” – foods especially purported to boost our immunity, prevent cancer, cure degenerative illnesses and generally keep us feeling young and healthy. In a recent paper, Pan et al. examine the science that exists to support these claims.1 They review signalling pathways that are associated with aging and degenerative diseases and explore how compounds contained in common foods may inhibit these pathways. A number of promising candidates found in fruits, vegetables, nuts, tea, spices and fish are presented. Lovers of chocolate and wine will also be heartened by the list of youth-promoting foods compiled. Read more here! ⇒

Study Confirms Anatomic Existence of the Elusive G-Spot

For centuries, women have been reporting engorgement of the upper, anterior part of the vagina during the stage of sexual excitement, despite the fact the structure of this phenomenon had not been anatomically determined.

A new study published in The Journal of Sexual Medicine documents that this elusive structure does exist anatomically.

Adam Ostrzenski, M.D., Ph.D., of the Institute of Gynecology in St. Petersburg, FL, conducted a stratum-by-stratum anterior vaginal wall dissection on an 83-year-old cadaver. The dissection established the presence of the G-spot, a well-delineated sac structure located on the dorsal (back) perineal membrane, 16.5 mm from the upper part of the urethral meatus, creating a 35 degree angle with the lateral (side) border of the urethra.

Having 3 distinct regions, the G-spot emerged with dimensions of length (L) of 8.1 mm x width (W) 3.6 mm to 1.5 mm x height (H) 0.4 mm. Upon removal of the entire structure with the adjacent margin tissues, the G-spot stretched from 8.1 to 33 mm.

“This study confirmed the anatomic existence of the G-spot, which may lead to a better understanding and improvement of female sexual function,” Ostrzenski concludes.

Irwin Goldstein, editor-in-chief of The Journal of Sexual Medicine believes that research in women’s sexual health issues is important. “This case study in a single cadaver adds to the growing body of literature regarding women’s sexual anatomy and physiology.”

Industrial Symbiosis – A Collection from JIE

Turning waste generated by one company into raw materials for another has long been one of the most intriguing notions in industrial ecology. This strategy, known as industrial symbiosis—by analogy to the manner in which some species in nature cooperate to mutual advantage— has become an important component of national environmental policies in countries ranging from China and Korea to the UK.

Yale’s Journal of Industrial Ecology is pleased to announce a special issue on industrial symbiosis that highlights research that moves beyond case studies to couple empirical research with theory-building. To complement the special issue, a selection of previously published articles on industrial symbiosis has been compiled by the journal.
