Swallowing‐Related Quality of Life After Carotid Body Tumor Resection: A Longitudinal Trajectory Analysis

Head &Neck, EarlyView.
ABSTRACT Objectives To identify longitudinal swallowing‐related QoL trajectories after carotid body tumor (CBT) resection and explore associated characteristics. Methods A prospective study assessed swallowing‐related QoL using the MD Anderson Dysphagia Inventory at nine timepoints from preoperation to 12 months postdischarge.

Commercial permethrin elicits chemoreceptive responses on different Anopheles gambiae sensory appendages

Pest Management Science, EarlyView.
Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.

HilD-regulated chemotaxis proteins contribute to Salmonella Typhimurium colonization in the gut

mBio
In the enteric pathogen Salmonella Typhimurium, invasion and motility are coordinated by HilD, a master regulator that activates expression of genes encoding the type III secretion system 1 and some motility genes, including the chemotaxis gene mcpC ...

Redox signaling in acute oxygen sensing

Redox Biology, 2017
Acute oxygen (O2) sensing is essential for individuals to survive under hypoxic conditions. The carotid body (CB) is the main peripheral chemoreceptor, which contains excitable and O2-sensitive glomus cells with O2-regulated ion channels.

Update on the Pathophysiology, Aetiology and Management of Central Sleep Apnoea

Respirology, EarlyView.
ABSTRACT Central sleep apnoea (CSA) of the periodic breathing type occurs during the transition between wakefulness and stage 1 and 2 non‐REM sleep. In adults at sea level, it occurs most commonly due to advanced heart failure (HF) or chronic opioid use and in ~5% of obstructive sleep apnoea patients initiating CPAP.

Fernando De Castro and the discovery of the arterial chemoreceptors

Frontiers in Neuroanatomy, 2014
When De Castro entered the carotid body (CB) field, the organ was considered to be a small autonomic ganglion, a gland, a glomus or glomerulus, or a paraganglion.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Reductive stress in mitochondria isolated from the carotid body of type 1 diabetic male Wistar rats

Physiological Reports
The carotid body (CB) senses changes in arterial O2 partial pressure (pO2) and glucose levels; therefore, it is key for the detection of hypoxia and hypoglycemia. The CB has been suggested to detect pO2 through an increase in reactive oxygen species (ROS)

Purines and Carotid Body: New Roles in Pathological Conditions

Frontiers in Pharmacology, 2017
It is known that adenosine and adenosine-5′-triphosphate (ATP) are excitatory mediators involved in carotid body (CB) hypoxic signaling. The CBs are peripheral chemoreceptors classically defined by O2, CO2, and pH sensors.

Research Progress on Upper Airway Cough Syndrome

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Upper airway cough syndrome (UACS) has been identified as a significant contributor to chronic cough in various national guidelines. However, the complexity of its pathogenesis, the lack of clarity surrounding its diagnostic criteria, and its overlap with other etiologies of chronic cough present considerable challenges in both diagnosis and ...
