Cholecystokinin (CCK) is a regulatory peptide released into the circulation after the ingestion of food. Our knowledge concerning the factors affecting its pattern of secretion in the mammalian neonate is scanty. Therefore, in this work we studied plasma concentrations of CCK in 3-day-old lambs after a sucking bout that followed either a short (2 h) or a long fasting period (9 h). Plasma concen...

new observations in recent years have accented differences between the two common hookworms, ancylostoma duodenale and necator americanus, with respect to modes of transmision and pathogenicity, and have established ancylostoma ceylanicum as a species distinct from a. braziliense. transmammary and paratenic transmission are now considered to be natural modes of infection in ancylostoma caninum ...

OBJECTIVE To determine whether correction of anemia of prematurity by packed red blood cell transfusion improves sucking. DESIGN Nonexperimental intervention study. SETTING Neonatal intensive care unit of Shaare Zedek Medical Center, Jerusalem, Israel, between July 23, 2006, and December 16, 2007. PATIENTS Thirty-six neonates at a gestational age of 34 weeks or younger, feeding orally, wh...

Jurassic fossils of a bizarre fly larva that lived in water as a blood-sucking parasite highlight how much can be learnt from the study of the fossils of immature insects.

Intraventricular pressures were measured during brief periods of mitral orifice occlusion to determine whether or not the ventricle am exert a sucking force during diastole. This procedure was based on the premise that with a wide open mitral orifice negative diastolic transmural pressures cannot be detected in the ventricle because the adjoining atrium has collapsible walls. During mitral orif...
