Computed tomographic manifestations of celiac ganglia between hypertensive and non‐hypertensive population

open access: yesThe Journal of Clinical Hypertension, 2023
The celiac ganglion (CG) is associated with the sympathetic nervous system (SNS) and plays an important role in the pathogenesis of hypertension. The characteristics of the CG in patients with hypertension remain unknown.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

RADIOFREQUENCY DENERVATION OF PULMONARY ARTERY IN SURGERY OF DYSPLASTIC MITRAL VALVE DEFECTS WITH SEVERE PULMONARY HYPERTENSION

open access: yesРоссийский кардиологический журнал, 2016
Pulmonary hypertension is an increase of pulmonary artery mean pressure for more than 25 mmHg at rest, measured by direct tensometry, and it includes a broad spectrum of diseases.

Atlantic Ocean Heat Transport Enabled by Indo-Pacific Heat Uptake and Mixing [PDF]

open access: yes, 2019
The ocean transports vast amounts of heat around the planet, helping to regulate regional climate. One important component of this heat transport is the movement of warm water from equatorial regions toward the poles, with colder water flowing in return.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

ATRIAL FIBRILLATION AFTER CARDIAC SURGERY: PATHOPHYSIOLOGY AND PREVENTION TECHNIQUES

open access: yesВестник анестезиологии и реаниматологии, 2017
Atrial fibrillation is one of the most frequent complications occurring after cardiac surgery. Post-operative atrial fibrillation confidently increases the risk of mortality and associated complications.

CircGSAP alleviates pulmonary microvascular endothelial cells dysfunction in pulmonary hypertension via regulating miR-27a-3p/BMPR2 axis

open access: yesRespiratory Research, 2022
Background Our previous study showed that circular RNA-gamma-secretase-activating protein (circGSAP) was down-regulated in pulmonary microvascular endothelial cells (PMECs) in response to hypoxia, and regulated the cell cycle of PMECs via miR-942-5p ...

On the structural changes in the Brewer-Dobson circulation after 2000 [PDF]

open access: yes, 2010
In this paper we present evidence that the observed increase in tropical upwelling after the year 2000 may be attributed to a change in the Brewer-Dobson circulation pattern.
