Utilização da ultrassonografia transcuneal como auxílio no diagnóstico da síndrome do navicular em eqüinos

The equine locomotors system alterations are very frequent and corresponds a large portion of cases in equine medicine. The most equine veterinarian’s challenge is to do a precise diagnosis of lameness cause to perform a specific and proper treatment as early as possible. The navicular syndrome is considered responsible for one third of lameness causes and, although much studied, its etiology is still not fully understood. The most varied methods of diagnosis, such as x-ray, magnetic resonance, bursography, scintigraphy, computed tomography and ultrasound, have been used to assess podotrochlear apparatus situation in order to diagnose this syndrome. Among them transcuneal ultrasound can be used to observe some important structures such as the flexor surface of distal sesamoid bone, distal deep digital flexor tendon, distal sesamoid ligament entheses odd and the distal phalanx. The aim of this present paper is provide a brief review on the use and the technique of ultrasonography on third phalanx transcuneal region evaluation and its interpretation on navicular syndrome diagnosis in horses

The nucleus of the solitary tract and the coordination of respiratory and sympathetic activities

It is well known that breathing introduces rhythmical oscillations in the heart rate and arterial pressure levels. Sympathetic oscillations coupled to the respiratory activity have been suggested as an important homeostatic mechanism optimizing tissue perfusion and blood gas uptake/delivery. This respiratory-sympathetic coupling is strengthened in conditions of blood gas challenges (hypoxia and hypercapnia) as a result of the synchronized activation of brainstem respiratory and sympathetic neurons, culminating with the emergence of entrained cardiovascular and respiratory reflex responses. Studies have proposed that the ventrolateral region of the medulla oblongata is a major site of synaptic interaction between respiratory and sympathetic neurons. However, other brainstem regions also play a relevant role in the patterning of respiratory and sympathetic motor outputs. Recent findings suggest that the neurons of the nucleus of the solitary tract (NTS), in the dorsal medulla, are essential for the processing and coordination of respiratory and sympathetic responses to hypoxia. The NTS is the first synaptic station of the cardiorespiratory afferent inputs, including peripheral chemoreceptors, baroreceptors and pulmonary stretch receptors. The synaptic profile of the NTS neurons receiving the excitatory drive from afferent inputs is complex and involves distinct neurotransmitters, including glutamate, ATP and acetylcholine. In the present review we discuss the role of the NTS circuitry in coordinating sympathetic and respiratory reflex responses. We also analyze the neuroplasticity of NTS neurons and their contribution for the development of cardiorespiratory dysfunctions, as observed in neurogenic hypertension, obstructive sleep apnea and metabolic disorders.

Moxonidine into the lateral parabrachial nucleus modifies postingestive signals involved in sodium intake control

The activation of a2-adrenoceptors with bilateral injections of moxonidine (a2-adrenoceptor and imidazoline receptor agonist) into the lateral parabrachial nucleus (LPBN) increases 1.8% NaCl intake induced by treatment with furosemide (FURO) + captopril (CAP) subcutaneously. In the present study, we analyzed licking microstructure during water and 1.8% NaCl intake to investigate the changes in orosensory and postingestive signals produced by moxonidine injected into the LPBN. Male Sprague–Dawley rats were treated with FURO + CAP combined with bilateral injections of vehicle or moxonidine (0.5 nmol/0.2 ll) into the LPBN. Bilateral injections of moxonidine into the LPBN increased FURO + CAP-induced 1.8% NaCl intake, without changing water intake. Microstructural analysis of licking behavior found that this increase in NaCl intake was a function of increased number of licking bursts from 15 to 75 min of the test (maximum of 49 ± 9 bursts/bin, vs. vehicle: 2 ± 2 bursts/bin). Analysis of the first 15 min of the test, when most of the licking behavior occurred, found no effect of moxonidine on the number of licks/burst for sodium intake (24 ± 5 licks/burst, vs. vehicle: 27 ± 8 licks/burst). This finding suggests that activation of a2-adrenoceptors in the LPBN affects postingestive signals that are important to inhibit and limit sodium intake by FURO + CAP-treated rats.

Study the production of Gustav Klimt is browsing through the history of a country, Austria, and travel the world of the Austro-Hungarian in their bellies. This work attempts to reflect the rebelliousness of the women who do not want to be sentenced to confinement despotic promoted by a man’s world. Klimt, by passion, hugs, with odd aesthetic, this flag.
