Corneal healing through apoptosis

By | May 16, 2001

The Arthus type allergic reaction in the cornea is characterised by inflammatory cell infiltration and marked neovascularisation. This gradually disappears during the healing stages through mechanisms that are not yet elucidated but which are essential to preserve vision. In the May British Journal of Ophtalomology, Noriko Ozaki and colleagues from the Nippon Medical School, Tokyo show that regression of the Arthus reaction in the cornea occurs via apoptosis.Ozaki et al injected bovine serum alb

A human urate transporter data sheet

By | May 15, 2001

High serum levels of uric acid are associated with an increased risk of developing gout, hypertension, cardiovascular disease and renal failure. Urate is produced as a result of purine degradation and as yet little is known about the pathway for urate efflux from cells. In the May Journal of Clinical Investigation Michael Lipkowitz and colleagues from the Mount Sinai School of Medicine, New York provide data on the human urate transporter galectin 9.Lipkowitz et al show that a recombinant protei

The 'Out-of-Africa' hypothesis posits that modern humans derive from an African originator population, that spread outward replacing local populations approximately 100,000 years ago. In the May 11 Science, Ke et al. report the use of Y chromosome polymorphism analysis to test the origins of modern Asian man (Science 2001, 292:1151-1153). They looked at 12,127 men from 163 different populations across Southeast and Central Asia and typed three Y chromosome biallelic markers (YAP, M89 and M130).
