Resistance to vascular wilt parasites

Netherlands Journal of Plant Pathology, 1968
When tomato plants resistant toVerticillium albo-atrum become infected with this fungus the parasite grows very little in the stem. The stem, however, responds by producing many tyloses. In susceptible tomato plants in which the parasite is more abundant few tyloses occur, but after some weeks when the parasite begins to disappear from the lower parts ...

Depressive Symptoms Are Associated With Increased Systemic Vascular Resistance to Stress

Psychosomatic Medicine, 2005
Objective: The deleterious effects of major depressive disorder on cardiovascular (CV) functioning are well known. However, the etiologic mechanisms underlying this association are incompletely understood.

Resistance to Flow in Vascular Beds [PDF]

Nature, 1959
CARLILL'S attempt1 to dispel confusion in the use of the Ohm's law analogy in blood circulation theory requires further clarification, since it is only the incorrect application of this analogy that needs to be abandoned not the analogy itself, but it raises an important point.

Relationship between the Resistive Index and Vascular Compliance and Resistance

Radiology, 1999
To evaluate the dependence of the resistive index (RI) on not only vascular resistance but also vascular compliance.An in vitro model that made use of a pulsatile pump, blood-mimicking fluid, and variable compliance and resistance was used to investigate the relationship between the RI and both vascular compliance and resistance.In the absence of ...

Carbon monoxide overproduced by heme oxygenase-1 causes a reduction of vascular resistance in perfused rat liver.

American Journal of Physiology - Gastrointestinal and Liver Physiology, 1999
This study aimed to examine whether livers overexpressing heme oxygenase (HO)-1 could alter the vascular resistance through the vasorelaxing action of carbon monoxide (CO).

Vascular resistance of the isolated rabbit kidney

Cryobiology, 1971
Abstract Isolated rabbit kidneys were perfused at 37 °C with a solution containing electrolytes, dextrose, dextran 70, and papaverine. The effects of recirculation, filtration, and the method of oxygenation of the perfusate were studied. A time-dependent increase in vascular resistance was observed when a bubble oxygenator was used and the perfusate ...

Effects of bisoprolol on local vascular resistance

European Heart Journal, 1987
Changes in systolic and diastolic blood pressure, heart rate, arterial blood flow and vascular resistance in the arm and in the leg were investigated in 9 healthy volunteers (22-40 years) after oral dosing with bisoprolol 10 mg, propranolol 40 mg, and placebo in a randomized double-blind cross-over study.

Distributions of vascular pressure and resistance in the lung

Journal of Applied Physiology, 1988
The low-viscosity bolus method was used to determine the longitudinal distributions of vascular resistance and intravascular pressure with respect to cumulative vascular volume from the lobar artery to the lobar vein in isolated dog lung lobes near functional residual capacity under zone 3 conditions.

Role of oxygenation and vascularization in drug resistance

1998
Oxygenation status and tumor vascularization seem to be important factors in determining therapeutic effectiveness and patient prognosis. An abundance of data on tumor oxygenation and vascularization is available and it clearly shows that most human solid tumors are heterogeneously oxygenated and vascularized. They contain hypoxic regions. Such regions
