Activating chalcogen bonding (ChB) in alkylseleno/ alkyltelluroacetylenes toward ChB directionality control
Activation of a deep electron‐deficient area on chalcogen atoms (Ch = Se, Te) is demonstrated here in alkynyl chalcogen derivatives, in the prolongation of the (C≡)C−Ch bond. The solid‐state structures of 1,4‐bis(methylselenoethynyl)perfluorobenzene (1Se) show the formation of recurrent chalcogen‐bonded (ChB) motifs. Association of 1Se and the tellurium analog 1Te with 4,4’‐bipyridine and with the stronger Lewis base 1,4‐di(4‐pyridyl)piperazine gives 1:1 co‐crystals with 1D extended structures linked...

Revealing the Magnesium‐Storage Mechanism in Mesoporous Bismuth via Spectroscopy and Ab‐Initio Simulations
The two‐step magnesium‐storage mechanism Bi↔MgBi↔Mg3Bi2 is proposed and comprehensively investigated via spectroscopy and ab‐initio methods. Theoretical computations confirm a significant electronic conductivity of MgBi and reveal a low reaction barrier of the two‐step path. In combination with nanoengineering design of mesoporous Bi nanosheets, a highly significant volume expansion (204 %) and Mg‐storage kinetics are regulated. Abstract We present mesoporous bismuth nanosheets as a model...

Microsurgical simulation, a ‘cheep’ solution
There is a demand for simulation-themed courses within maxillofacial surgery, yet these are often expensive. With this in mind, we used a non-living chicken thigh model to simulate microsurgical procedures on a training day for specialty registrars. The advantages and limitations of the simulation were explored through participant feedback. This model was found to be a useful, cost-effective simulation which was valued by trainees within our specialty.

Evolution of surgical modalities in the management of rhinophyma: our experience
Rhinophyma is a progressive disease of the nose, which is characterised by skin thickening and sebaceous hyperplasia. Patients with rhinophyma are often stigmatised due to worsening disfigurement of their nose. This can also result in functional impairment such as reduced nasal patency. Severe cases of rhinophyma are best managed with varied surgical interventions, as there is no clear ‘gold standard’ treatment that has been described. We present our experiences in the management of rhinophyma and...

Distinct populations of amygdala somatostatin-expressing neurons project to the nucleus of the solitary tract and parabrachial nucleus
AbstractRostral forebrain structures such as the central nucleus of the amygdala (CeA) send projections to the nucleus of solitary tract (NST) and the parabrachial nucleus (PBN) that modulate taste-elicited responses. However, the proportion of forebrain-induced excitatory and inhibitory effects often differ when taste cell recording changes from the NST to the PBN. The present study investigated whether this descending influence might originate from a shared or distinct population of neurons marked...

How ambient environment influences olfactory orientation in search and rescue dogs
AbstractUnder natural conditions, an animal orienting to an air-borne odor plume must contend with the shifting influence of meteorological variables, such as air temperature, humidity and wind speed, on the location and the detectability of the plume. Despite their importance, the natural statistics of such variables are difficult to reproduce in the laboratory and hence few studies have investigated strategies of olfactory orientation by mobile animals under different meteorological conditions....

Response dependence of reversal‐related ERP components in perception of ambiguous figures
Abstract Perceptual multi‐stability is characterized by alternating interpretations of an unchanging stimulus input. The reversal negativity (RN) and reversal positivity (RP) ERP components show differences in electrophysiological responses between trials on which participants experience a perceptual reversal of a multi‐stable stimulus versus trials without a reversal (i.e., stable). However, it is unclear to what extent these two ERP components reflect reversal‐related perceptual processing rather...

Endometrial Cancer, the Current International Federation of Gynecology and Obstetrics Staging System, and the Role of Imaging
Imaging plays a crucial role in the diagnosis, staging, and follow-up of endometrial cancer. Endometrial cancer is staged surgically using the International Federation of Gynecology and Obstetrics (FIGO) staging system. Preoperative imaging can complement surgical staging but is not yet considered a required component in the current FIGO staging system. Preoperative imaging can help identify some tumor characteristics and tumor spread, both locally and distally. More accurate assessment of endometrial...

A sleep epidemic or enlightenment? A Bayesian approach to test the sleep epidemic hypothesis shows foragers have short and fragmented sleep compared to large scale societies [NEW RESULTS]
Human sleep is linked with nearly every aspect of our health and wellbeing. The question whether and to what extent human sleep is in a state of evolutionary mismatch has gained recent attention from both clinical and biological science researchers. Here, I use a comparative Bayesian approach aimed at testing the sleep epidemic hypothesis, the idea that, due to labor demands and technological disruption, sleep-wake activity is negatively impacted in post-industrial, economically developed societies....
