The pulmonary circuit receives the whole of the cardiac output, and the flow through it is governed by events in the systemic circulation. Its function is gaseous exchange, and the low resistance and high capacitance of the circuit is subservient to this function. Local flow is affected by intra-alveolar oxygen tensions and regional flow by passive hydrostatic effects due to gravity. The distri...

Since the National Organ Transplant Act of 1984, the number of people receiving organs each year has increased [1]. Unfortunately, the number of donations has not kept up with the number of patients needing them, resulting in a severe shortage of organs [1]. This requires that we allocate organs as efficiently as possible. Currently in the U.S., organs are allocated at a local, regional, and na...

The aim of this study was to investigate intra-regional activation and inter-regional connectivity during passive movement. During fMRI, a mechanic device was used to move the subject's index and middle fingers. We assessed four movement conditions (unimanual left/right, bimanual symmetric/asymmetric), plus Rest. A conventional intra-regional analysis identified the passive stimulation network,...

BACKGROUND AND PURPOSE The main aim of our study was to assess the cerebrovascular thrombolytic efficacy of different tissue plasminogen activator treatment protocols with Doppler ultrasound. METHODS We occluded one internal carotid artery in 48 New Zealand White rabbits with whole blood emboli. Five minutes later the rabbits were assigned to receive one of the following tissue plasminogen ac...

OBJECTIVE We conducted a prospective study among Japanese Americans of diabetes incidence in relation to visceral and regional adiposity, fasting insulin and C-peptide, and a measure of insulin secretion, because little prospective data exist on these associations. RESEARCH DESIGN AND METHODS Baseline variables included plasma glucose, C-peptide, and insulin measured after an overnight fast a...

Over the next several years, grid-based photochemical models such as the community multiscale air quality (CMAQ) model, the regional modeling system for aerosols and deposition (REMSAD), the comprehensive air quality model with extensions (CAMx), and other regional models will be used by regulatory agencies in the United States for designing emission control strategies to meet and maintain the ...

UNLABELLED To assess quantitatively regional nutritive muscular blood flow in patients with peripheral vascular disease (PVD), we evaluated the utility of PET with 15O-water. METHODS Eight healthy volunteers and 16 patients with angiographically proven PVD were studied. Regional blood flow of the calf was measured with 15O-water PET during rest, after intra-arterial infusion of prostaglandin ...

Functional organization of the brain can be fundamentally altered by auditory deprivation. Previous studies found that the superior temporal cortex in deaf people is reorganized to process non-auditory stimuli, as revealed by the extrinsic task-induced brain activities. However, it is unknown how the intrinsic activities of this region are impacted by deafness. This study explored this issue us...

Server localization refers to introduction of local servers that are connected to a main centralized server. The banking system currently prevailing in the country maintains two databases: one for transaction management while the other is maintained for backup. The transactional data from various branches across the country is maintained by a centralized server. In this scenario, given one cent...

-According to the "epinephrine hypothesis," circulating epinephrine taken up by sympathetic nerves is coreleased with norepinephrine during sympathetic stimulation and binding of coreleased epinephrine to presynaptic beta-adrenoceptors augments exocytotic release of norepinephrine, contributing to high blood pressure. This study examined whether infusion of a physiologically active amount of ep...
