Pediatric atresia magnets

A medical system for approximating the esophageal sacs in an infant afflicted with esophageal atresia. The medical device includes an esophageal catheter and a gastric catheter. The distal end of the esophageal catheter, which includes a magnetic tip, is passed through the esophagus to the upper esophageal sac. The distal end of the gastric catheter, which also includes a magnetic tip, is passed through a gastrostomy and into the lower esophageal sac. The magnetic forces created by both magnets results in approximation of the esophageal sacs. Pressure-induced necrosis establishes a passageway between the esophageal sacs. A stent or stent-graft can be deployed within the established passageway to prevent re-stenosis of the esophagus.

Mammalian pro-apoptotic Bok genes and their uses

Nucleic acid compositions encoding a pro-apoptotic protein, Bok (Bcl-2-related ovarian killer) are identified. Bok has conserved Bcl-2 homology domains 1, 2 and 3 and a C-terminal transmembrane region present in other Bcl-2 related proteins, but lacks the BH4 domain found only in anti-apoptotic Bcl-2 proteins. Over-expression of Bok induces apoptosis. Cell killing induced by Bok is suppressed by co-expression with selective anti-apoptotic Bcl-2 proteins. Bok is highly expressed in the ovary, testis and uterus, particularly in granulosa cells, the cell type that undergoes apoptosis during follicle atresia. Identification of Bok as a new pro-apoptotic protein with wide tissue distribution and hetero-dimerization properties facilitates elucidation of apoptosis mechanisms in reproductive and other tissues, and provides a means for manipulating apoptosis.
