Determination of Cerebral Cortical Capillary Blood Volume from Mean Transit Time Analysis
Advances in Experimental Medicine and Biology, 1987A full understanding of the delivery of oxygen to a tissue cannot be attained by study of the blood flow to that tissue alone. An important component of the delivery system is the particular spatial arrangement of the capillaries supplying the tissue.

Changes in cerebral blood volume due to augmented or diminished numbers of blood-perfused capillaries can be studied in small animals by optical methods. Capillary mean transit time was determined by detection of the passage of a hemodilution bolus through a region of the parietal cerebral cortical surface, using a reflectance spectrophotometer through

The study aims to determine the possible improvement in cortical transit time (CTT) after surgery in infants with antenatally diagnosed ureteropelvic junction obstruction (UPJO), and investigate the correlation of CTT with preoperative renal function and parenchymal thickness.Medical charts of 32 antenatally diagnosed children with UPJO operated on ...

Summary Functional connectivity (FC) can provide insight into cortical circuit dysfunction in neuropsychiatric disorders. However, dynamic changes in FC related to locomotion with sensory feedback remain unexplored. To investigate FC dynamics in locomoting mice, we developed mesoscopic Ca 2+

1. The influence of intrarenal blood-flow distribution and plasma transit-time through the renal cortex on the reduction in p-aminohippurate (PAH) extraction (EPAH) induced by renal vasodilator agents was evaluated in anaesthetized dogs by an indicator-dilution technique. 2.

In children with antenatally detected hydronephrosis caused by ureteropelvic junction (UPJ) stenosis, the main challenge is preserving renal function by identifying children who require early surgical intervention from those for whom watchful waiting may be appropriate because of the potential for spontaneous resolution without a significant loss of ...

Ureteropelvic junction obstruction (UPJO) is a frequent cause of congenital hydronephrosis (CHN). There is no gold standard diagnostic test for UPJO. Serial diuretic renogram is often used as a surrogate for diagnosing UPJO. Cortical transit time (CTT) is a renogram parameter reported helpful for management.
