The current state of NIH funding of research in diagnostic radiology at U.S. medical schools.

The research grant awards data for 2003 published by the National Institutes of Health (NIH) were analyzed to obtain a snapshot of the current state of diagnostic radiology research in US medical schools. By considering awards to diagnostic radiology departments only, the authors show that NIH departmental rankings that combine diagnostic and therapeutic radiology departments together are deceptive for researchers interested primarily in diagnostic radiology. For each diagnostic radiology grant analyzed, the authors examined the source of funding, the primary modality involved in the research, the activity classification of the grant, and the degree of the associated principal investigator.

Delayed blood reoxygenation following maximum voluntary contraction.

Purposes: To characterize the total hemoglobin concentration ([THb]) and oxyhemoglobin saturation (%HbO2) time courses after brief dorsiflexion maximal voluntary contractions (MVC) and to determine whether these responses varied by gender.

Methods: Eighteen healthy, moderately physically active subjects (nine male) lay supine and performed two or more 3-s dorsiflexion MVC. [THb] and %HbO2 were measured continuously in the tibialis anterior muscle using near-infrared spectroscopy (NIRS).
