Juvenile polyps of the duodenum are rare and nearly always occur in the context of a more widespread gastrointestinal juvenile polyposis. Clinical features and neoplastic risk are less significant, although there is a case report of a duodenal carcinoma occurring in a patient with familial juvenile polyposis. Most of the polyps resemble the more common sporadic juvenile polyp of the colon, bein...

Juvenile perpetrated sexual aggression has been a problem of growing concern in American society over the past decade. Currently it is estimated that juveniles account for up to one-fifth of the rapes, and one-half of the cases of child molestation committed in the United States each year. The majority of cases of juvenile sexual aggression appear to involve adolescent male perpetrators; howeve...

Within a few hours after injection of juvenile hormone into Hyalophora gloveri pupae, several fast-migrating carboxylesterases (EC 3.1.1.1) that are sensitive to diisopropylfluorophosphate appear in the hemolymph. Treatment of the pupae with puromycin or actinomycin D prevents the appearance of these hemolymph enzymes, suggesting de novo synthesis of the carboxylesterases. Of the several other ...

Natural disasters such as Hurricane Katrina have resulted in the displacement of families to locations throughout the nation. Juvenile courts have been affected by this mass migration of youths. Post-disaster recovery has been slow. Consequently, a cohort of youths has aged out of the juvenile justice system before their juvenile competency hearings could be held. Some of these young adults now...

Additional somatosensory contact of preterm human infants improves a variety of developmental assessment scores, but less is known about its lasting consequences. In rodents, maternal contact may influence the programming of juvenile social play behavior. Therefore, we used a paradigm where we can control the levels of somatosensory contact associated with maternal care. We find that additional...

The various life stages of the Dungeness crab, Cancer magister, may experience broad environmental fluctuations in both salinity and temperature, parameters that can affect nearly all aspects of their physiological function. The routine rates of oxygen uptake of megalopa, first and fifth instar juvenile and adult C. magister were measured, using closed vessel respirometry over 8 h during acute ...
