The molecular mechanism of pH sensing by chemoreceptors is not clear, although it had been proposed to be mediated by a drop in intracellular pH of carotid body glomus cells, which inhibits a K+ current. Recently, pH-sensitive ion channels have been described in glomus cells that respond directly to extracellular acidosis. In this study, we investigated the possible molecular mechanisms of carotid body pH-sensing by recording the responses of glomus cells isolated from rat carotid body to rapid changes in extracellular pH using whole-cell patch-clamping technique. Extracellular acidosis evoked transient inward currents in glomus cells that were evident at pH 7.0 and half-activated (pH 50) at 6.3. The current had the characteristics of ASICs. It averaged 40.7±15.7 pA (n=5) at pH 5.0 and was blocked by the ASIC channel blocker amiloride (200 μm) to 2.5±1.6 pA. Na+ free bathing solution eliminated the current and a Ca2+ free buffer enhanced (P,0.05) the current at pH 6.0 from 18.5±2.2 to ...
Afferent chemoreceptor activity was recorded from the peripheral cut end of the carotid sinus nerve in pentobarbitone anaesthetized cats. The effects of purines, peptides and ouabain on chemosensory activity were studied. Purines. It was found that intracarotid injections of adenosine: AMP; ADP; ATP; CoA;Me-adenosine analogues: N6-methyladenosine, 2-chloroadenosine, 3-deoxyudenosine but not 2-deoxyadenosine; cyclic AMP; dibutyryl cyclic AMP increased spontaneous chemoreceptor discharge. The ATP analogues, a-5- methylene ATP decreased spontaneous chemoreceptor discharge, whereas the f-y-methylene ATP caused a slight increase in discharge. Adenine and the purine nucleosides inosine and guanosine had little or no effect on the discharge. The pyrimidine nucleosides cytidine and uridine were also studied and had little or no effect on spontaneous chemoreceptor discharge. Intracarotid injection of theophylline transiently depressed spontaneous chemosensory activity and potentiated the action of ...

In the present study, we investigated the effects of neuronal NO synthase (nNOS) gene transfer on CB chemoreceptor activity in CHF rabbits. The nNOS protein expression and NO production were suppressed in CBs (P,0.05) of CHF rabbits, but were increased 3 days after application of an adenovirus expressing nNOS (Ad.nNOS) to the CB. As a control, nNOS and NO levels in CHF CBs were not affected by Ad.EGFP. Baseline single-fiber discharge during normoxia and the response to hypoxia were ...
The inappropriate sustained SNA increase in OSA patients likely contributes to hypertension, organ damage, and mortality; however, it is unclear how excessive SNA develops in these patients. Several factors, including obesity and increased carotid body chemoreceptor sensitivity due to intermittent hypoxia, have been considered. Obesity could mechanically obstruct the airway and increase SNA through leptin, insulin, angiotensin, and cytokine actions; however, many OSA patients are not obese (23). Carotid body hypersensitivity as a result of intermittent hypoxia has been confirmed in animal models of OSA. In fact, plasticity of the carotid body glomus cells with long-term sensory facilitation and sensitization have been reported (18, 24) and associated with ROS and NOX2-dependent accumulation of HIF1 and the transcriptional coactivator CREB-binding protein (25). Central neuroplasticity. A provocative possibility for OSA-associated SNA dysfunction is that excessive activation of CNS nuclei induces ...
Abstract: Carbon dioxide retention is common in divers during water immersion. This puts divers at risk for carbon dioxide toxicity. The carotid body chemoreceptors contribute to the control of ventilation and when blood oxygen content is high, ventilation decreases. This results in the increased risk of carbon dioxide retention. Therefore, we are investigating the role of the carotid body chemoreceptors in ventilatory control during hyperbaric exposures when blood oxygen content is elevated ...
Increased sympathetic activity is a well-known pathophysiological mechanism in insulin resistance (IR) and hypertension (HT). The carotid bodies (CB) are peripheral chemoreceptors that classically respond to hypoxia by increasing chemosensory activity in the carotid sinus nerve (CSN), causing hyperventilation and activation of the sympathoadrenal system. Besides its role in the control of ventilation, the CB has been proposed as a glucose sensor implicated in the control of energy homeostasis. However, to date no studies have anticipated its role in the development of IR. Herein, we propose that CB overstimulation is involved in the etiology of IR and HT, core metabolic and hemodynamic disturbances of highly prevalent diseases like the metabolic syndrome, type 2 diabetes, and obstructive sleep apnoea. We demonstrate that CB activity is increased in IR animal models and that CSN resection prevents CB overactivation and diet-induced IR and HT. Moreover, we show that insulin triggers CB, ...

jdempsey{at}wisc.edu. Question: Does the carotid body response to chronic intermittent hypoxia (CIH) differ between neonates and adults?. Background: The carotid body is a sensory organ located near the bifurcation of the carotid artery and is responsible for detecting changes in the partial pressure of oxygen in arterial blood. In adult rodents, during CIH, the carotid body is theorized to evoke the reflexes that mediate cardiorespiratory changes and results in a long-lasting increase in baseline sensory activity known as sensory long-term facilitation (LTF). In contrast to adults, the carotid bodies of neonatal rodents are immature and respond poorly to hypoxia. To better understand the physiology of neonatal carotid bodies, Pawar et al. explored whether CIH evokes sensory LTF and whether the effects of CIH are reversible in neonatal carotid bodies.. Observations: CIH augmented the hypoxic sensory response in both adults and neonates; however, the neonates displayed more susceptibility to the ...
The study was approved by the Local Animal Care and Use Committee of the Karolinska Institute, Stockholm, Sweden. Seven adult New Zealand White rabbits weighing 3860 +/− 270 g (mean +/− SD) were included. After an initial dose of intravenous thiopental, 75-100 mg, given via a marginal ear vein, a tracheostomy was performed after an anterior midline skin incision. Mechanical ventilation (ETCO(2), 4.0-5.0%) was initiated at a rate of 33 breaths/min using a mixture of oxygen and air (FIO(2) 0.30), whereas the inspired tidal volume was adjusted to maintain isocapnia throughout the experiment. Anesthesia was maintained with a continuous thiopental infusion of 10.5 +/− 0.9 mg [middle dot] kg-1[middle dot] h-1(range, 9.4-12.0) given via a right femoral vein catheter. The right femoral artery was cannulated for continuous arterial blood pressure monitoring and arterial blood gas analysis (ABL 300 Laboratory [registered sign], Radiometer, Copenhagen, Denmark). On-line analysis of inspired and ...

Background K+ channels of the TASK family are believed to participate in sensory transduction by chemoreceptor (glomus) cells of the carotid body (CB). However, studies on the systemic CB-mediated ventilatory response to hypoxia and hypercapnia in TASK1- and/or TASK3-deficient mice have yielded conflicting results. We have characterized the glomus cell phenotype of TASK-null mice and studied the responses of individual cells to hypoxia and other chemical stimuli. CB morphology and glomus cell size were normal in wild-type as well as in TASK1/ or double TASK1/3/ mice. Patch-clamped TASK1/3-null glomus cells had significantly higher membrane resistance and less hyperpolarized resting potential than their wild-type counterpart. These electrical parameters were practically normal in TASK1/ cells. Sensitivity of background currents to changes of extracellular pH was drastically diminished in TASK1/3-null cells. In contrast with these observations, responsiveness to hypoxia or ...
The carotid body (CB) is the main arterial chemoreceptor in charge of adjusting ventilatory and cardiovascular function during changes in arterial blood gases. Regardless this essential function, the CB has been implicated in the sensing of other physiological signals such as changes in blood flow and glucose levels. More important, malfunction of the CB chemoreceptors has been associated with the progression and deterioration of several disease states such as hypertension, heart failure, renal failure, insulin resistance, diabetes and sleep apnea. Although the mechanisms involved in the alterations of the CB function in pathophysiology are currently under intense research, the development of therapeutic approaches to restore normal CB chemoreflex function remains unsolved. Recently, elegant studies showing the effect of CB neurotomy in pathophysiology have unveiled a key role of these arterial chemoreceptors in the development of autonomic imbalance and respiratory disturbances, and suggest that
The mechanism of oxygen sensing in arterial chemoreceptors is unknown but has often been linked to mitochondrial function. A common criticism of this hypothesis is that mitochondrial function is insensitive to physiological levels of hypoxia. Here we investigate the effects of hypoxia (down to 0.5% O2) on mitochondrial function in neonatal rat type-1 cells. The oxygen sensitivity of mitochondrial [NADH] was assessed by monitoring autofluorescence and increased in hypoxia with a P50 of 15 mm Hg (1 mm Hg = 133.3 Pa) in normal Tyrode or 46 mm Hg in Ca(2+)-free Tyrode. Hypoxia also depolarised mitochondrial membrane potential (m, measured using rhodamine 123) with a P50 of 3.1, 3.3 and 2.8 mm Hg in normal Tyrode, Ca(2+)-free Tyrode and Tyrode containing the Ca(2+) channel antagonist Ni(2+), respectively. In the presence of oligomycin and low carbonyl cyanide 4-(trifluoromethoxy) phenylhydrazone (FCCP; 75 nm) m is maintained by electron transport working against an artificial proton leak. Under these

This surgery does not involve any study drug or investigational device.. The carotid body will be removed by the so called lateral approach or a combined lateral and medial approach. In all cases the target area was defined as the tissue in between the ECA and ICA, up to 5-6mm above the bifurcation point of the common carotid artery into the ECA and ICA. In a lateral approach the carotid bifurcation is not turned. A combined approach includes usually dissection of the superior thyroid vessel and turning of the carotid bifurcation. ...
Position and source of blood supply to the human carotid body displays population variations. These data are important during surgical procedures and diagnostic imaging in the neck but are only scarcely reported and altogether missing for the Kenyan population. The aim of this study was to describe the position and blood supply of the carotid body in a Kenyan populati on. A descriptive cross-sectional study at the Department of Human Anatomy, University of Nairobi, was designed. 136 common carotid arteries and their bifurcations were exposed by gross dissection. The carotid body was identified as a small oval structure embedded in the blood vessel adventitia. Position and source of blood supply were photographed. Data are presented by tables and macrographs. 138 carotid bodies were identified. Commonest position was carotid bifurcation (75.4%) followed by external carotid artery (10.2%), internal carotid artery (7.2%) and ascending pharyngeal artery (7.2%).

Body types can determine what physical activities match your needs and what you would eat to supply your routines. Weight loss plan based on your body type.
The recent insights we have about food have shown that a calorie is quite a rough parameter to quantify food with. Even in the same person, a calorie had a different consequence on the body depending on the source of the calorie and the digestion of the person at that moment. There can be a huge difference between people in the way food is processed. Some can eat eight slices of pizza without gaining an ounce, while others will bloat just by looking at it. If we wish to feed ourselves correctly, we need to understand how food acts and how we process food personally, according to our body type. Food is not only a bunch of calories created to still our hunger and fool our senses; it contains information like software code written by nature to feed and upgrade our inner intelligence. Food should thus be considered medicine and the cook a doctor. This leads us to knowledge of our body type and the necessity for a proper diagnosis before choosing what to eat, as food will restore our balance ...

The carotid body is a small structure weighing 12 mg located in the adventitia of carotid artery bifurcation acting as a chemoreceptor. Carotid body tumour (CBT); formerly known as chemodectoma is a rare, highly vascular, mostly benign tumour arising from the paraganglia of carotid body; hence, the name (carotid paraganglioma). The high vascularity and proximity to cranial nerves and major vessels make this tumour a surgical challenge. Abundant literature has been written about CBT in the last century with a continuous debate regarding its etiology, natural history, biological behavior, proper technique of excision, and the morbidity and mortality associated with its resection. The purpose of this review article is to simplify understanding the basic and clinical aspects of this challenging neoplasm.
Hypoxic chemotransduction in the carotid body requires release of excitatory transmitters from type I cells that activate afferent sensory neurones. Transmitter release is dependent on voltage-gated Ca2+ entry which is evoked by membrane depolarization. This excitatory response to hypoxia is initiated by inhibition of specific O2 sensitive K+ channels, of which several types have been reported. Here, we discuss mechanisms which have been put forward to account for hypoxic inhibition of type I cell K+ channels. Whilst evidence indicates that one O2 sensitive K+ channel, BKCa, may be regulated by gasotransmitters (CO and H2S) in an O2-dependent manner, other studies now indicate that activation of AMP-activated protein kinase (AMPK) accounts for inhibition of both BKCa and leak O2 sensitive K+ channels, and perhaps also other O2sensitive K+ channels reported in different species. We propose that type I cell AMPK activation occurs as a result of inhibition of mitochondrial oxidative phosphorylation, and

Injections of 20-300 μl bicarbonate solution evoked changes in respiratory frequency and in peak phrenic nerve discharge. The membrane potential of inspiratory alpha neurons, whether bulbospinal or not and independent of their anatomic location, was decreased during inspiration. A sequence of compound excitatory and inhibitory effects were observed when the stimulus was given ...
Hypoxic inhibition of K+ channels in type I cells is believed to be of central importance in carotid body chemotransduction. We have recently suggested that hypoxic channel inhibition is mediated by AMP-activated protein kinase (AMPK). Here, we have further explored the modulation by AMPK of recombinant K+ channels (expressed in HEK293 cells) whose native counterparts are considered O2-sensitive in the rat carotid body. Inhibition of maxiK channels by AMPK activation with AICAR was found to be independent of [Ca2+]i and occurred regardless of whether the α subunit was co-expressed with an auxiliary β subunit. All effects of AICAR were fully reversed by the AMPK inhibitor compound C. MaxiK channels were also inhibited by the novel AMPK activator A-769662 and by intracellular dialysis with the constitutively active, truncated AMPK mutant, T172D. The molecular identity of the O2-sensitive leak K+ conductance in rat type I cells remains unclear, but shares similarities with TASK-1 and TASK-3. Recombinant
Endomorphic body type shown here. Constitutional psychology is a theory, developed in the 1940s by American psychologist William Herbert Sheldon, associating body types with human temperament types. Sheldons somatotypes and their supposed associated physical traits can be summarized as follows: Ectomorphic: characterized by long and thin muscles/limbs and low fat storage; receding chin, usually referred to as slim. Mesomorphic: characterized by medium bones, solid torso, low fat levels, wide shoulders with a narrow waist; usually referred to as muscular. Endomorphic: characterized by increased fat storage, a wide waist and a large bone structure, usually referred to as fat. - Stock Image C027/6278
Exposure to acute hypoxia elicits a ventilatory response that is subject to various time-dependent phenomena, some of which occur during hypoxia (eg. hypoxic ventilatory decline) while others appear upon return to normoxia (eg. post-hypoxic frequency decline). In addition, memory components to the response exist, associated with repeated, acute hypoxic exposures (eg. progressive augmentation). Although central mechanisms, either downstream of afferent peripheral chemoreceptor input or through the direct effects of hypoxia on the brainstem, are sufficient to elicit these phenomena, little is known about the possible contribution of mechanisms arising from the carotid body. To investigate this further, we used an arterially perfused, en bloc rat carotid body preparation. Male rats (150-250g) were deeply anaesthetized in halothane (2 ml kg-1 within a 4 l chamber) until respiration ceased and animals failed to respond to a noxious paw pinch. Animals were then transected below the diaphragm, and the ...
