Specific biological characteristics of Xylella fastidiosa (Xf) Temecula were investigated in microfluidic flow chambers in vitro by examining the effect of xylem sap from Pierce’s disease (PD) susceptible V. vinifera and resistant V. smalliana grapevines on Xf cell growth, aggregation, biofilm formation, and motility. Growth of Xf was observed in both V. smalliana and V. vinifera xylem saps in ...

AIMS We wanted to study the effects of a 600 micrograms inhaled salbutamol dose on the cardiovascular and respiratory autonomic nervous regulation in eight children suffering from bronchial asthma. METHODS In this randomized, double-blind, placebo-controlled, crossover study we continuously measured electrocardiogram, finger systolic arterial pressure (SAP) and flow-volume spirometry at basel...

Experiments were designed to determine 1) the mechanisms mediating metaboreflex-induced increases in systemic arterial pressure (SAP) in response to total vascular occlusion of hindlimb blood flow [e.g., increases in cardiac output (CO) vs. peripheral vasoconstriction] and 2) whether the individual mechanisms display differential latencies for the onset of the responses. Responses were observed...

Recent studies have shown that stomata respond to changes in hydraulic conductance of the flow path from soil to leaf. In open-grown tall trees, branches of different heights may have different hydraulic conductances because of differences in path length and growth. We determined if leaf gas exchange, branch sap flux, leaf specific hydraulic conductance, foliar carbon isotope composition (delta...

OBJECTIVE To evaluate the agreement of blood pressure measurements and hypertension scores obtained by use of 3 indirect arterial blood pressure measurement devices in hospitalized dogs. Design-Diagnostic test evaluation. ANIMALS 29 client-owned dogs. PROCEDURES 5 to 7 consecutive blood pressure readings were obtained from each dog on each of 3 occasions with a Doppler ultrasonic flow detec...

Under extreme drought and climate change, golden pear trees have experienced problems such as yield reduction, dryness death. This suggests that we know very little about the mechanisms regulating tree growth, assuming meteorological factors positively influence plant sap flow. Based on this, used heat ratio method to monitor flow of from June December 2020, recorded changes in various environm...

Inflammation is a part of the initial process leading to atherosclerosis and cholesterol crystals (CC), found in atherosclerotic plaques, which are known to induce complement activation. The pentraxins C-reactive protein (CRP), long pentraxin 3 (PTX3), and serum amyloid P component (SAP) are serum proteins associated with increased risk of cardiovascular events and these proteins have been show...

Salinity damage in rice and other salt-sensitive species is due to excessive transport of NaCl through the root system to the leaves and consequently low salt transport to the shoot can be a major trait determining salt resistance. Since the rapid uptake of sodium ions is such a crucial part of the response of rice to salinity, physiological experiments were carried out to compare bypass flow i...

We tested for reductions in water transport with increasing tree size, a key component in determining whether gas exchange and growth are hydraulically limited in tall trees. During the summers of 1998 and 1999, we measured water transport with Granier-type, constant-heat sap flow probes, vapor pressure deficit, and leaf and soil water potentials in overstory Pseudotsuga menziesii (Mirb.) Franc...
