Clearance of p16‐positive cardiac cells improves age‐related cardiac remodeling in mice

Experimental Physiology, EarlyView.
Abstract Senescent cells are characterized by expression of markers like p16 and secretion of profibrotic and proinflammatory factors. The role of cellular senescence in age‐related cardiac remodeling and dysfunction is incompletely understood. This study aimed to: (i) evaluate the effect of p16‐ positive cell clearance on cardiac function and ...

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

Experimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

Experimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Investigation of placental circulations by color Doppler ultrasonography

American Journal of Obstetrics and Gynecology, 1991
The placental circulations of 25 normal and five complicated pregnancies were studied by color Doppler ultrasonography. Flow velocity waveforms were obtained in all 30 pregnancies and could discriminate between fetal and maternal intraplacental blood flow.

Hysterosalpingography with color Doppler ultrasonography

American Journal of Obstetrics and Gynecology, 1991
To assess the accuracy of the diagnosis of tubal occlusion with the use of color Doppler flow ultrasonography and hysterosalpingography, 129 infertile women were studied. All 129 women had the procedure performed with an ATL Ultramark 9 (Advanced Technology Laboratories, Bothel, Wash.) color Doppler ultrasonography machine. Eighty-five of the 129 women

Doppler and color Doppler ultrasonography in renal transplants: Chronic rejection

Journal of Clinical Ultrasound, 1992
AbstractAlthough Doppler and color Doppler ultrasonography has been used extensively to examine acute changes in renal allograft function, there have been few reports on the role of Doppler ultrasonography in the assessment of chronic rejection. In those studies that have addressed chronic rejection, there is agreement that changes in renal function ...

Ultrasonography and color Doppler-based triage for adnexal masses to provide the most appropriate surgical approach

American Journal of Obstetrics and Gynecology, 2005
Objective: This study was undertaken to identify whether ultrasonography with color Doppler can identify and triage the patients with adnexal masses to the most appropriate surgical approach.
