Obstructive sleep apnoea (OSA) is a sleep-related breathing condition that involves the presence of episodic disruptions to the sleeping pattern due to partial or complete airway obstruction. There are a range of treatment options that exist to alleviate the symptoms of this condition including CPAP, mandibular advancement, and maxillary expansion techniques. This systematic review and meta-analysis of published articles aims to determine if rapid maxillary expansion ("RME") is an effective treatment option in the management of OSA, using quantitative parameters of AHI and SpO.

The brain has evolved mechanisms to dynamically modify blood flow, enabling the timely delivery of energy substrates in response to local metabolic demands. Several such neurovascular coupling (NVC) mechanisms have been identified, but the vascular signal transduction and transmission mechanisms that enable dilation of penetrating arterioles (PAs) remote from sites of increased neuronal activity are unclear. Given the exponential relationship between vessel diameter and blood flow, tight control of arteriole membrane potential and diameter is a crucial aspect of NVC.

Defining the substrates of Resistance-Nodulation-Division (RND) systems is often complicated by the presence of multiple systems in a single bacterial species. Using a major efflux knockout strain, we developed a system that enables controlled expression of MexXY-OprM in the absence of background efflux complexes with overlapping substrate profiles. This system identified three groups of potential substrates: substrates, partial substrates, and nonsubstrates, and defined trimethoprim as a new substrate for MexXY-OprM.
