The development of the vertebrate brain requires an exquisite balance between proliferation and differentiation of neural progenitors. Notch signaling plays a pivotal role in regulating this balance, yet the interaction between signaling and receiving cells remains poorly understood. We have found that numerous nascent neurons and/or intermediate neurogenic progenitors expressing the ligand of ...

Colonies of Stylophora pistillata maintained for four years in indoor aquaria in the near absence of ultraviolet radiation (UVR) contained only small amounts (,5 nmol mg21 protein) of 10 identified mycosporine-like amino acids (MAAs, which act as UV sunscreens), the largest number reported in any organism. The concentrations of most MAAs increased linearly or exponentially when colonies were ex...
متن کاملA rare cause of massive lower gastrointestinal bleeding; jejunal Dieulafoy's lesion.
For the first time was defined by Dieulafoy in 1898, more than three cases of massive gastric hemorrhage,which is caused in a dilated submucosal artery (1). Dieulafoy's lesion, a rare cause of gastrointestinal bleeding is the submucosal arterial malformation (2). These lesions usually localized to the proximal of gastric lesser curvature, 6 cm away from the gastroesophageal junction in the stom...
