Magnetic Resonance Imaging of Gastric Motility in Conscious Rats

Neurogastroenterology &Motility, EarlyView.
By training rats to remain awake inside an MRI scanner, we can now noninvasively scan their gastrointestinal tracts without using anesthesia. This allows us to assess gastric motility and emptying in conscious rats without the various confounding effects that anesthesia might cause.

A Review of the Mechanisms of Action of the Herbal Medicine, STW 5‐II, Underlying Its Efficacy in Disorders of Gut–Brain Interaction

Neurogastroenterology &Motility, EarlyView.
The pathophysiology of functional dyspepsia and irritable bowel syndrome includes altered motility, secretion, sensitivity to sensory signals, impaired epithelial barrier function, inflammation, and gut dysbiosis. The phytomedicine, STW 5‐II, represents a multi‐targeted approach, addressing these pathophysiologies.

Determination of Ophthalmic Parameters and Ocular Morphology in Ring‐Necked Parakeets (Psittacula krameri)

Veterinary Ophthalmology, EarlyView.
ABSTRACT Purpose To determine normal ophthalmic test values and to describe the ocular morphology of ring‐necked parakeets (Psittacula krameri). Materials and Methods 33 captive birds were examined, although not all tests were conducted on each bird.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Nitrite supplementation alleviates cerebrovascular dysfunction in chronically stressed mice, but cognitive decline remains

Experimental Physiology, EarlyView.
Abstract This study aimed to determine whether sodium nitrite supplementation prevented chronic stress‐induced cerebrovascular dysfunction and cognitive decline. We hypothesize that nitrite supplementation will prevent the oxidative environment and cerebrovascular dysfunction associated with chronic stress and maintain cognitive health.
