Renal Vascular Resistance in Sepsis
Nephron Physiology, 2006Aims: To assess changes in renal vascular resistance (RVR) in human and experimental sepsis and to identify determinants of RVR. Methods: We performed a systematic interrogation of two electronic reference libraries using specific search terms.

Pulmonary vascular resistance [PDF]
Intensive Care Medicine, 2003 Almost 20 years ago, Adriaan Versprille published an editorial in this journal to explain why, in his opinion, the calculation of pulmonary vascular resistance (PVR) is meaningless [1]. The uncertainties of PVR were underscored a year later by McGregor and Sniderman in the American Journal of Cardiology [2]. Obviously, both papers failed to convince. A

Pulmonary vascular resistance and vascular transmural gradient
Journal of Applied Physiology, 1960Perfusion studies were made on vascular beds of isolated dog lungs. Submerged, gas-free, fluid-distended lobes served for studies of resistance versus transmural pressure in a technique that abolished gravitational effects. Air-distended lobes with varying degrees of pulmonary edema were used to display the transmural gradient differences produced by ...

Estrogen and vascular resistance
Current Opinion in Endocrinology & Diabetes, 1999Male sex and menopause are independent risk factors for cardiovascular disease. Estrogens bind to vascular receptors, including the novel estrogen receptor-β and membrane-bound receptors, and they contribute to vascular resistance through several mechanisms.

Mechanotransduction and Vascular Resistance [PDF]
, 2014 Mechanotransduction is the process by which any cell transduces (converts) a mechanical signal into chemical cues. The vessel wall is permanently sheared by the moving blood particles as well as stretched and compressed by the pressure applied by the blood.

Resistance to Flow in Vascular Beds [PDF]
Nature, 1958 DR. S. D. CARLILL1 has attacked the standard concept of resistance to flow (R) as the ratio of the driving force (the pressure drop P across the bed) to the flow F, and advocates that the ‘dynamic resistance’, that is, the differential dP/dF be substituted. His argument seems to assume what he is trying to prove.

Vascular resistance in splenic perfusion
Journal of Surgical Research, 1968Abstract Eighteen pig spleens have been perfused ex vivo, 9 each with heterologous and homologous blood. Angiographic evidence of spasm in the main splenic arteries probably caused the temporary early resistance to perfusion, with both homologous and heterologous blood.
