The Journal of Physiology, EarlyView.Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Culture of arterial chemoreceptor cells from adult cats in defined medium
Brain Research, 1994 Recently patch clamp techniques and optical fluorometric techniques have been applied to freshly dissociated or cultured carotid body. However, very few studies have shown the effects of the dissociation and/or culture conditions on the health and function of the cells. The purpose of this study was to develop a culture method which support healthy and

The Journal of Physiology, EarlyView.Abstract figure legend Exacerbated ATP signalling in the carotid body (CB) of spontaneously hypertensive rats (SHRs) arises from expansion of the chemosensory glomus cell compartment and reduced extracellular ATP metabolism, leading to increased purinergic drive.

Identification of the YfgF MASE1 domain as a modulator of bacterial responses to aspartate [PDF]
, 2013 Complex 3'-5'-cyclic diguanylic acid (c-di-GMP) responsive regulatory networks that are modulated by the action of multiple diguanylate cyclases (DGC; GGDEF domain proteins) and phosphodiesterases (PDE; EAL domain proteins) have evolved in many bacteria.

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities
The Journal of Physiology, EarlyView.Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

Challenges in the Management of Massive Carotid Body Tumor
Case Reports in OtolaryngologyThe carotid body paraganglioma is a rare benign neoplasm arising from the chemoreceptor cells of the carotid bulb. The carotid body has the largest collection of paraganglia in the head and neck with 60–70% of head and neck paraganglioma. Paraganglia are

Spectral Tuning of Chemoreceptor Cells of the Third Maxilliped of the Lobster, Homarus americanus.
The Biological Bulletin, 1992 This is the first investigation of the spectral tuning properties of single chemoreceptor cells of the third maxillipeds (mouthparts) of the lobster Homarus americanus. These organs are used, among other functions, for chemical recognition of food. Based

Development of whole cell biosensors mediated by bacteria chemoreceptors (614.5)
The FASEB Journal, 2014 Whole cell biosensors are part of an emerging strategy to build new tools for diagnostic and therapeutic applications. The goal is to re‐engineer bacterial cells to respond to environmental cues or chemicals. Whole cell biosensors typically express a sensor protein targeting the ligand of interest that is coupled with a genetic regulatory system to ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes
The Journal of Physiology, EarlyView.Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

GPCRs Direct Germline Development and Somatic Gonad Function in Planarians.
PLoS Biology, 2016 Planarians display remarkable plasticity in maintenance of their germline, with the ability to develop or dismantle reproductive tissues in response to systemic and environmental cues. Here, we investigated the role of G protein-coupled receptors (GPCRs)
