Management of sizeable carotid body tumor: Case report and review of literature

open access: yesAvicenna Journal of Medicine, 2013
Carotid body tumor is a paraganglioma derived from the neural crest. It arises from the carotid body which acts as a vascular chemoreceptors and is usually located at the carotid bifurcation.

Aging is associated with an earlier arrival of reflected waves without a distal shift in reflection sites [PDF]

open access: yes, 2016
Background-Despite pronounced increases in central pulse wave velocity (PWV) with aging, reflected wave transit time (RWTT), traditionally defined as the timing of the inflection point (T-INF) in the central pressure waveform, does not appreciably ...

Current Approaches and Challenges in Advanced Oxidation Processes for Nanoplastic Degradation

open access: yesAdvanced Science, EarlyView.
This review explores recent progress in advanced oxidation processes (AOPs) for the degradation of nanoplastics (NPs) in water. It presents a comparative assessment of key AOP technologies and identifies current limitations in analytical methods and treatment efficiency.

Tasting Arterial Blood: What do the Carotid Chemoreceptors Sense?

open access: yesFrontiers in Physiology, 2015
The carotid bodies are sensory organs that detect the chemical composition of the arterial blood. The carotid body sensory activity increases in response to arterial hypoxemia and the ensuing chemoreflex regulates vital homeostatic functions.

MECHANISMS OF DISEASE Acute Oxygen-Sensing Mechanisms [PDF]

open access: yes, 2005
JOSEPH PRIESTLEY, ONE OF THE THREE SCIENTISTS CREDITED WITH THE discovery of oxygen, described the death of mice that were deprived of oxygen. However, he was also well aware of the toxicity of too much oxygen, stating, “For as a candle burns much faster

Design of A Flexible Liquid Metal Tactile Sensor Based on Finite Element Analysis for Pressure and Motion Detection

open access: yesAdvanced Electronic Materials, EarlyView.
In this study, a PVA sacrificial template method is proposed to fabricate microfluidic LM pressure sensors, and LM conductive pathway patterns are designed using FEA. Their study revealed that symmetric patterns and thinner microchannels significantly enhanced the pressure sensitivity of the sensor.

Factors associated with cardiovascular events after simultaneous liver–kidney transplant from the US Multicenter Simultaneous Liver–Kidney Transplant Consortium

open access: yesHepatology Communications, EarlyView., 2022
Abstract Cardiovascular disease is a leading complication after both liver and kidney transplantation. Factors associated with and rates of cardiovascular events (CVEs) after simultaneous liver–kidney transplant (SLKT) are unknown. This was a retrospective cohort study of adult SLKT recipients between 2002 and 2017 at six centers in six United Network ...

Peritoneal dialysis in older adults: evaluation of clinical, nutritional, metabolic outcomes, and quality of life [PDF]

open access: yes, 2018
The number of older adults requiring dialysis is increasing worldwide, whereas the use of peritoneal dialysis (PD) in this population is lower respect to younger patients, despite the theoretical advantages of PD respect to hemodialysis.

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.

Relationship between Dietary Intake and Body Composition with Carotid Intima-Media Thickness in Patients with Transient Ischemic Attack

open access: yesمجله دانشکده پزشکی اصفهان, 2017
Background: Population-based studies in many countries have shown that carotid intima-media thickness (IMT) has a positive relationship with stroke. Some studies have suggested that many of the foods or body composition have effect on the risk of stroke.
