We have carried out a deep (t=30000s) x-ray search of the eastern portion of the L1495 cloud centered on the well known weak line T Tauri star (WTTS) V410 Tau using the ROSAT PSPC. This deep exposure enabled a search for candidate pre-main sequence (PMS) objects in this cloud to a limit ∼ 20 times more sensitive than that typical of the fields examined with the Einstein searches. Despite assert...

Puberty represents a particular period of life characterized by hormonal changes and physical and psychological modifications leading children from childhood to adolescence. During this period, menarche represents the most important event in females. Age of menarche is different among populations and has been recognized as an useful marker of socio-economic status, as well as dietary and enviro...

This paper deepens the connections between critically finite rational maps and finite subdivision rules. The main theorem is that if f is a critically finite rational map with no periodic critical points, then for any sufficiently large integer n the iterate f is the subdivision map of a finite subdivision rule. We are interested here in connections between finite subdivision rules and rational...

The kinetics of potassium tail currents have been studied in the omohyoid muscle of the rat using the three-microelectrode voltage-clamp technique. The currents were elicited by a two-pulse protocol in which a conditioning pulse to open channels was followed by a test step to varying levels. The tail currents reversed at a single well-defined potential (VK). At hyperpolarized test potentials (-...

Fibrocystic disease of the pancreas was first described by Landsteiner in 1905, and it is of interest, that intestinal obstruction was one of the features of his case. Since then, and particularly in the past two decades, many well authenticated cases have been described. Andersen (1938), described three clinicalsyndromes as being associated with essentially the same pathological lesion in the ...

ALTHOUGH congenital atresia of the cesophagus is comparatively rarely diagnosed, it is, as will be shown, a not uncommon congenital anomaly, and since early treatment now offers a chance of complete cure we have felt it worth while to make the following short summary of the literature on the subject, with notes on the clinical appearances of typical cases. The condition has been reported in the...

THE DEVELOPMENT of a successful surgical treatment for Hirschsprung's disease 11 and the establishment of a sound pathologic and etiologic basis 3 for the disease have been among the most gratifying events in Pediatric Surgery of the last decade. The result has been to render accurate diagnosis possible with precision. At the same time the knowledge that an effective surgical treatment is avail...

Human heart Na 1 channels were expressed transiently in both mammalian cells and Xenopus oocytes, and Na 1 currents measured using 150 mM intracellular Na 1 . Decreasing extracellular permeant ion concentration decreases outward Na 1 current at positive voltages while increasing the driving force for the current. This anomalous effect of permeant ion concentration, especially obvious in a mutan...
