For decades, the sphere eversion has been a favorite subject for mathematical visualization. The 1998 video The Optiverse shows minimax eversions, computed automatically by minimizing elastic bending energy using Brakke’s Evolver. We contrast these geometrically optimal eversions with earlier ones, including those by Morin, Phillips,

Inflammatory bowel disease (IBD) has become common in the Western world, but its causes remain unclear. With the dramatic increase of cases in Asia in recent years—echoing the disease's drastic rise in the West decades earlier—investigators have another shot at studying environmental contributors to IBD as it emerges in new populations.

colorectal cancer remains one of the major cancer- related deaths despite progress in the treatment during past decades. detection of disease at earlier stages reduces its mortality. the aim of current study was to investigate expression of cytokeratin 19 (ck19), cytokeratin 20 (ck20) and guanylyl cyclase c (gcc) mrna in peripheral blood of non- metastatic colorectal cancer patients which may r...
