Neural crest cells (NCCs) can adopt different neuronal fates. In NCCs, neurogenin-2 promotes sensory specification but does not specify different subclasses of sensory neurons. Understanding the gene cascades that direct Trk gene activation may reveal mechanisms generating sensory diversity, because different Trks are expressed in different sensory neuron subpopulations. Here we show in chick a...

Since low birth weight is a leading cause of infant mortality,7 varying rates of this outcome among Hispanic subgroups may translate to similarly varying patterns in infant mortality. On the other hand, if access to neonatal intensive care services differs by maternal birthplace or ethnicity, then infant mortality rates might not reflect differences in low-birth-weight rates among Hispanic subg...

Volume 29, Number 4, July/August 1997 language would, in practice, have serious unintended consequences, such as nullifying laws allowing minors to obtain confidential reproductive health care and other sensitive health services, disrupting school sex education and AIDS prevention activities, and impeding the removal of children from abusive homes. However, the outcome also appears to reflect a...

this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...

Objective. To determine the diagnostic accuracy of placental alpha microglobulin-1 assay and standard diagnostic methods for detecting rupture of membrane. Study Design. Prospective diagnostic study, between June 2011 to November 2011 at a tertiary centre. Initial evaluation included both the standard diagnostic methods for rupture of membranes and placental alpha microglobulin-1 immunoassay. T...

We study a new s-process path through an isomer of Re to improve a Re-Os nucleo-cosmochronometer. The nucleus Re is produced by this new path of Re(n,γ)Re(n,γ)Re. We measure a ratio of neutron capture cross-sections for the Re(n,γ)Re and Re(n,γ)Re reactions at thermal neutron energy because the ratio with the experimental uncertainty has not been reported. Using an activation method with reacto...

This study was conducted to investigate the low prevalence of Dirofilaria immitis in dogs in Johor Bahru as reported by veterinary practitioners, using wet blood mount, Knott’s Concentration Test and two heartworm antigen test kits (IDEXX Canine SNAP® 4Dx and RapiGEN®). This study also compared the two test kits used and determined the microfilaria species. Blood were collected from 100 owned d...
