Acute intermittent hypoxia in neonatal rodent central nervous system facilitates respiratory frequency through the recruitment of hypothalamic areas

Experimental Physiology, EarlyView.
Abstract Moderate and acute intermittent hypoxia (IH) facilitates respiration in adults, mostly by recruiting peripheral chemo‐/baroreceptors. As central chemoreceptors are widely expressed in immature brains, we hypothesized that IH modulates respiration at birth through a purely neurogenic mechanism involving the hypothalamus.

Endovascular repair for acute traumatic transection of the descending thoracic aorta: experience of a single centre with a 12-years follow up [PDF]

, 2015
Background: Most blunt aortic injuries occur in the proximal proximal descending aorta causing acute transection of this vessel. Generally, surgical repair of the ruptured segment of aorta is associated with high rates of morbidity and mortality and in

Inference of gene loss rates after whole genome duplications at early vertebrates through ancient genome reconstructions [PDF]

arXiv, 2018
The famous 2R hypothesis was first proposed by Susumu Ohno in 1970. It states that the two whole genome duplications had shaped the genome of early vertebrates. The most convincing evidence for 2R hypothesis comes from the 4:1 ratio chromosomal regions that have preserved both gene content and order in vertebrates compared with closely related. However,

Cardiac conduction system and the electrocardiogram of the common hippopotamus (Hippopotamus amphibius)

Experimental Physiology, EarlyView.
Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...

DENTAL CHAIR VERTEBRAL ARTERY DISSECTION

Romanian Journal of Oral Rehabilitation, 2017
Extradural vertebral artery dissection is a condition with a generally good prognosis if it is promptly recognized and treated. Diagnosis and consequently therapy delay may cause extensive ischemia with catastrophic consequences, due to embolism from the

The effect of end-range cervical rotation on vertebral and internal carotid arterial blood flow and cerebral inflow: a sub analysis of an MRI study [PDF]

, 2015
Introduction: Cervical spine manual therapy has been associated with a small risk of serious adverse neurovascular events, particularly to the vertebral arteries. Sustained end-range rotation is recommended clinically as a pre-manipulative screening tool;

Cranial Arterial Perfusion of the Tympanic Bullae Region in Llamas (Lama glama): Anatomic Features and Anomalies

Anatomia, Histologia, Embryologia, Volume 54, Issue 4, July 2025.
ABSTRACT The tympanic bulla of South American camelids is a unique multi‐compartmental structure with an internal architecture resembling that of honeycomb. This unique configuration creates surgical challenges for the treatment of refractory otitis media cases in llamas (Lama glama).

Investigation of extracranial internal carotid and vertebral artery dissection after cervical spine manipulation

Annals of Vascular Surgery - Brief Reports and Innovations, 2023
Objective: Cervical artery dissection (CAD) is considered one of these complications in the treatment of cervical spine manipulation (CSM), which can lead to severe complications such as stroke or death.

Steroid Receptors and Vertebrate Evolution [PDF]

arXiv, 2019
Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone ...
