Open AccessEffectiveness and process evaluation in obesity and type 2 diabetes prevention programs in children: a systematic review and meta-analysis
Obesity in children is one of the most severe public health challenges of the current century and Type 2 Diabetes Mellitus (T2DM) frequency is also escalating. More so, the importance of process evaluation (PE...

Open AccessMolecular and morphological characterization of new interspecific hybrids of alstroemeria originated from A. caryophylleae scented lines
Alstroemeria is a genus native to South America from which many varieties of ornamental plants have been developed and introduced into the market. Interspecific hybridization followed by embryo rescue has been on...

Fifty Years of Progress in Carotid Body Physiology – Invited Article
Research on arterial chemoreceptors, particularly on the carotid body, has been fruitful in the last fifty years, to which this review is addressed. The functional anatomy of the organ appears to be well estab...

Domperidone as a Tool to Assess the Role of Dopamine within Carotid Body Chemoreception
The carotid bodies are composite receptors, i.e. hypoxia apparently acts upon glomus cells which are synaptically apposed to the sensory endings of primary afferent neurons, responsible for conveying the informat...

Coherence of Chemosensory Discharges in Cats’ Carotid Nerves
The study of neural coding involves the analysis of four formal aspects: the referent (relevant features of the input), the transformation (encoding process), the transmission (anatomical and physiological substr...

Dopamine Efflux from the Carotid Body During Hypoxic Stimulation
The carotid bodies of cats are known to contain high levels of dopamine (DA), persisting even after complete denervation of these organs (Zapata et al, 1969; Mir et al, 1982; Fitzgerald et al, 1983). Thus DA a...

Effects of Expiratory Duration on Chemoreceptor Oscillations
We have studied the effect of suddenly altering the duration of expiration (TE) on the variations in the frequency of chemosensory discharges (fx) with respiration.

The Carotid Bodies as Thermosensors: Experiments in Vitro and in Situ, and Importance for Ventilatory Regulation
The carotid bodies are not only sensitive to changes in the chemical composition of the blood, but also to changes in flow, osmolality and temperature (Eyzaguirre & Zapata, 1984). We have been searching for th...

Thermal Effects Upon the Chemosensory Drive of Ventilation
It has been shown that the frequency of chemosensory discharges recorded from carotid bodies superfused in vitro is highly dependent on temperature (Gallego et al., 1979), presenting both dynamic and static co...

Flow Detection by the Carotid Body
The carotid bodies (CBs) of the cat are excited by occlusions of the common carotids (1), resulting in reflex hyperventilation (2). The CBs are also responsive to systemic hypotension, although less than the a...

Plasticity of Ventilatory Chemoreflexes
The chemosensory neurons of the carotid (sinus) and aortic (depressor) nerves provide the input for the ventilatory chemoreflexes initiated by hypoxic stimulation. The central processes of these neurons conver...

Restoration of Chemoreflexes after Unilateral Carotid Deafferentation
The main arterial chemoreceptor organs in mammals are the carotid and aortic bodies. Each carotid body receives its sensory innervation from the carotid (sinus) branch of the ipsilateral glossopharyngeal nerve...

Carotid Body Chemoreceptor Response to Transient Arterial Occlusion
The occlusion of the common carotid artery is a classical manoeuvre to evoke a reflex increase in the systemic arterial pressure (Pa). This pressor response is usually ascribed to the withdrawal of carotid bar...

Interference by Domperidone on Chemosensory and Ventilatory Responses to Dopamine
The peripheral arterial chemoreceptors exert a tonic drive upon resting ventilation in normoxic eucapnic mammals as shown by the fall in tidal volume (VT) observed in response to breathing 100% O2 for a few secon...

Blockade of Carotid Body Chemosensory Inhibition
There is a high content of dopamine in the carotid body (21), located in glomus type I cells by fluorescence microscopy (9). Intrastream injections of dopamine produced a transient depression of the frequency ...

Recovery of Chemosensory Function of Regenerating Carotid Nerve Fibers
The site at which physiological stimuli elicit carotid nerve activation is still disputed. To evoke an increase in discharge in slowly adapting receptors (such as carotid body chemoreceptors), stimuli must dep...

Origin of Nerve Terminals on Glomus Cells in Cat Carotid Body: A Study of Axoplasmic Movement of Labeled Material Along Sensory Neurons of the Petrosal Ganglion
The site of termination of chemosensory fibers in the carotid body, once considered to be well established by the pioneering studies of de Castro (3), has been the object of renewed interest and speculation. D...

Effects of denervation and decentralization upon taste buds
Denervation of vallate papillae results in failure of tactile and gustatory reception at a time when impulse conduction in the distal stump of the glossopharyngeal nerve is still unimpaired; delay of receptor ...
