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 ...

Adaptation kinetics in bacterial chemotaxis [PDF]

, 1983
Cells of Escherichia coli, tethered to glass by a single flagellum, were subjected to constant flow of a medium containing the attractant alpha-methyl-DL-aspartate. The concentration of this chemical was varied with a programmable mixing apparatus over a

The genome and stage‐specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions

Insect Molecular Biology, EarlyView.
Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

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.

Location and architecture of the Caulobacter crescentus chemoreceptor array [PDF]

, 2008
A new method for recording both fluorescence and cryo-EM images of small bacterial cells was developed and used to identify chemoreceptor arrays in cryotomograms of intact Caulobacter crescentus cells.

Sex differences in loop gain measured via superimposed end‐expiratory breath holds and inspired steady‐state hypoxia

Experimental Physiology, EarlyView.
Abstract Acute low oxygen exposure (hypoxia) elicits a hypoxic ventilatory response (HVR), which increases ventilation and mitigates hypoxaemia. During sustained exposure to hypoxia, ventilatory acclimatization increases peripheral chemoreflex (HVR) sensitivity or chemoreflex loop gain (LG).

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.

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

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.

Widespread depolarization during expiration: A source of respiratory drive? [PDF]

, 2014
Respiration influences various pacemakers and rhythms of the body during inspiration and expiration but the underlying mechanisms are relatively unknown.
