A novel technique, based on cytotoxicity-neutralization, was developed for the in vitro titration of anti-sheep lymphocyte and anti-sheep macrophage sera. The titres obtained for a number of antisera were compared with those found in an agglutination assay. Anti-lymphocyte sera with a high cytotoxicity-neutralization titre very effectively suppressed the number of circulating lymphocytes in the...

IMPORTANCE Evaluation of pediatric obstructive sleep apnea in resource-limited health care systems necessitates testing modalities that are accurate and more cost-effective than polysomnography. OBJECTIVE To trace the clinical pathway of children referred to our sleep laboratory for possible obstructive sleep apnea who were evaluated using nocturnal pulse oximetry and the McGill Oximetry Scor...

Pulse oximetry is a technique for estimating arterial oxygen saturation continuously and non-invasively. Reflectance pulse oximetry might become useful for monitoring the fetus during labour but it is much more susceptible to all kinds of physiological variations than the well-established transmission pulse oximetry for neonatal or adult monitoring. This review focuses on the accuracy of reflec...

introduction robinow syndrome (rs) is an infrequent genetic condition that is characterized by a dysmorphic face, dental anomaly, short stature, mesomelic limb shortening, hand and foot anomalies, and hypoplastic genitalia. the robinow syndrome has been reported from the arab countries and other asian countries, but has not been reported in iranian population so far. case presentation a new bor...

Over the years many techniques have been devised for the measurement of tissue oxygenation (oximetry). Oximetry using polarographic needle electrodes has long been considered a gold standard. Nuclear Magnetic Resonance (NMR) based oximetry uses exogenously administered reporter molecules such as perfluorocarbons to quantitatively interrogate oxygen tension (pO2). This technique has been success...

Neurons born in new places eurogenesis in the adult brain is generally considered to be restricted to the hippocampus and olfactory bulb—ancient parts of the brain that are found even in nonmammalian species. A few publications suggested that the neocortex—a well-developed region in primates that is implicated in higher thought—also supports neurogenesis. These reports have been met with skepti...
