PLANET (the Probing Lensing Anomalies NETwork) is a worldwide collaboration of astronomers whose primary goal is to monitor microlensing events densely and precisely in order to detect and study anomalies that contain information about Galactic lenses and sources that would otherwise be unobtainable. The results of PLANET’s highly successful first year of operation are presented here. Details o...
AIM To explore mutations in serine/threonine kinase 11 (STK11) gene in Peutz-Jeghers syndrome (PJS) with gastrointestinal (GI) hamartomatous polyps. METHODS Six Japanese PJS patients in 3 families were enrolled in this study. Each of the cases had hamartomatous polyposis in the gastrointestinal tract, including the small intestine, along with mucocutaneous hyperpigmentation. Narrow-band imagi...
Signal transduction properties of exendin-4 (Ex-4) underlying its ability to stimulate rat insulin I gene promoter (RIP1) activity were assessed in the pancreatic beta-cell line INS-1. Ex-4 acted via glucagon-like peptide-1 receptors to stimulate RIP1 in a glucose-dependent manner, as measured in cells transfected with a -410-bp RIP1-luciferase construct (RIP1-Luc). The action of Ex-4 was indep...
We analyze five years of PLANET photometry of microlensing events toward the Galactic bulge to search for the short-duration deviations from single lens light curves that are indicative of the presence of planetary companions to the primary microlenses. Using strict event selection criteria, we construct a well defined sample of 43 intensively monitored events. We search for planetary perturbat...
Gel electrophoresis o f the white flocculent pheromone disseminating secretions produced by males o f the three dung beetle species, Kheper lamarcki, K. nigroaeneus and K. subaeneus, re vealed that three different proteins with molecular masses o f ca. 15 kDa are the major constitu ents o f these secretions. The molecular mass o f these components in the secretions o f K. lamarcki and K. nigr...
