to stimulatory actions of pituitary gonadotropins, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and placental gonadotropin, i.e., chorionic gonadotropin (CG), in primates. Until recently, it had never been thought that the reproductive tract could directly respond to pituitary or ...
Several centimeters (Orf and Schultheiss, 1981), up to 40 times the nerve diameter (Maki et al., 1997), of the nerve can be exposed and freed from surrounding tissue without significant deficit in perfusion, as long as the extrinsic vascular supply is left intact. Sign in to download full...
perfusion-weighted MR imagingThe diagnosis and treatment of small bowel obstruction continue to evolve. The imaging approach in the work-up of patients with known or suspected small bowel obstruction and the timing of surgical intervention in this disease have undergone considerable changes over the ...

Not only does CEUS allow for evaluation of real-time blood flow, but this imaging technique can also provide absolute quantification of tissue perfusion without giving any radiation to the patient. Since the microbubbles can produce robust signals, a lower IV dosage is required compared to MRI ...
In dynamical systems this refers to time-dependent states evolving towards an attractor. Balloon–Windkessel haemodynamic model A dynamical model in which neural activity (the BOLD signal) is transduced into brain perfusion changes. In this model, the BOLD signal is taken to be a static nonlinear ...

Perfusion of the inner ear: Basic science considerations For many years, formidable physiologic and anatomic barriers to management of the inner ear have existed, limiting our ability to manage symptoms such as vertigo, tinnitus, and sensorineural hearing loss. Local application of drugs to th... ...

To heal a wound or ischemic ulcer, good perfusion of the area is required, and therefore, the segment's revascularization becomes crucial for healing. The objectives of the preoperative evaluation are to recognize medical comorbidities to minimize the potential perioperative complications and mortality....
