People Are Less Susceptible to Illusion When They Use Their Hands to Communicate Rather Than Estimate.

When we use our hands to estimate the length of a stick in the Müller-Lyer illusion, we are highly susceptible to the illusion. But when we prepare to act on sticks under the same conditions, we are significantly less susceptible. Here, we asked whether people are susceptible to illusion when they use their hands not to act on objects but to describe them in spontaneous co-speech gestures or conventional sign languages of the deaf.

Ovarian cancer metastatic to the breast presenting as inflammatory breast cancer: a case report and literature review.

Background. Primary ovarian carcinoma with metastasis to the breast is rare, with only 39 cases reported in the current literature. Ovarian metastasis to the breast presenting as inflammatory breast carcinoma is even more infrequent, with only 6 cases reported.

Influence of prenatal nicotine exposure on development of the ventilatory response to hypoxia and hypercapnia in neonatal rats.

In a recent study (Huang YH et al. Respir Physiol Neurobiol 143: 1-8, 2004), we showed that prenatal nicotine exposure (PNE) increased the frequency of spontaneous apneic events on the first 2 days of life in unanesthetized neonatal rats. Here we test the hypothesis that PNE blunts chemoreceptor reflexes.

Influence of prenatal nicotine exposure on postnatal development of breathing pattern.

To determine if prenatal nicotine exposure alters the postnatal development of the ventilatory pattern and the frequency and duration of apneas, we recorded respiratory airflow with head-out body plethysmography in awake neonates on postnatal days 1, 2, 6, 10, 14, and 18. Data from 12 nicotine-exposed animals were compared with data from 12 saline-exposed animals. Nicotine (6 mg/kg of nicotine tartrate per day) or saline exposure was induced by osmotic minipumps that were implanted subdermally on the fifth day of gestation in Sprague-Dawley Dams.
