A virtual aortic annular plane that is built using the three hinge-points, known as hinge-point based annular plane (HPAP), is routinely used during transcatheter aortic valve replacement (TAVR). Abnormal aortic cusps (AAC) with unequal length and size significantly influence the relationship of HPAP to the aortic root axis and pose challenges to valve deployment leading to paravalvular leak and valve embolization. Obtaining a centerline based aortic annular plane, in addition, may help in better understanding of valve deployment behavior in AAC.AIMS To investigate the association of pre-stenting intravascular ultrasound (IVUS) evaluation on procedural and clinical outcomes for diffuse lesions treated with drug-eluting stent (DES). METHODS AND RESULTS In four randomised trials comparing IVUS- and angiography-guided DES placement, a total of 1396 patients who underwent DES implantation with IVUS guidance were identified. Pre-stenting IVUS assessment were performed in 905 patients along with post-stenting IVUS (65%; pre-stenting IVUS(+) group). Post-stenting IVUS evaluation alone was conducted on 491 patients (35%; pre-stenting IVUS(-) group). The pre-stenting IVUS(+) group had a larger angiographic minimal lumen diameter and IVUS-derived minimal stent area (MSA) than did the pre-stenting IVUS(-) group. After adjusting, these findings were consistent. The one-year composite of cardiac death, myocardial infarction, and target-vessel revascularisation did not differ between groups. On the subgroup analyses, pre-IVUS(+) group was significantly favoured over pre-IVUS(-) group in the subset of acute myocardial infarction and the lesions with small vessels as for the larger MSA, and in the subset of chronic total occlusions as for the better clinical outcomes. CONCLUSIONS Pre-stenting IVUS assessment prior to DES placement was associated with better acute procedural outcomes, though it was not translated to 1-year clinical outcomes in the context of post-stenting IVUS assessment.What mechanisms underlie facial expression recognition? A popular hypothesis holds that efficient facial expression recognition cannot be achieved by visual analysis alone but additionally requires a mechanism of motor simulation - an unconscious, covert imitation of the observed facial postures and movements. Here, we first discuss why this hypothesis does not necessarily follow from extant empirical evidence. Next, we report experimental evidence against the central premise of this view we demonstrate that individuals can achieve normotypical efficient facial expression recognition despite a congenital absence of relevant facial motor representations and, therefore, unaided by motor simulation. This underscores the need to reconsider the role of motor simulation in facial expression recognition. © 2020, Vannuscorps et al.Most glucose is processed in muscle, for energy or glycogen stores. Malignant Hyperthermia Susceptibility (MHS) exemplifies muscle conditions that increase [Ca2+]cytosol. 42% of MHS patients have hyperglycemia. We show that phosphorylated glycogen phosphorylase (GPa), glycogen synthase (GSa) - respectively activated and inactivated by phosphorylation - and their Ca2+-dependent kinase (PhK), are elevated in microsomal extracts from MHS patients' muscle. Glycogen and glucose transporter GLUT4 are decreased. [Ca2+]cytosol, increased to MHS levels, promoted GP phosphorylation. Imaging at ~100 nm resolution located GPa at sarcoplasmic reticulum (SR) junctional cisternae, and apo-GP at Z disk. MHS muscle therefore has a wide-ranging alteration in glucose metabolism high [Ca2+]cytosol activates PhK, which inhibits GS, activates GP and moves it toward the SR, favoring glycogenolysis. The alterations probably cause these patients' hyperglycemia. For basic studies, MHS emerges as a variable stressor, which forces glucose pathways from the normal to the diseased range, thereby exposing novel metabolic links. © 2020, Tammineni et al.Caveolae are bulb-shaped invaginations of the plasma membrane (PM) that undergo scission and fusion at the cell surface and are enriched in specific lipids. However, the influence of lipid composition on caveolae surface stability is not well described or understood. Accordingly, we inserted specific lipids into the cell PM via membrane fusion and studied their acute effects on caveolae dynamics. We demonstrate that sphingomyelin stabilizes caveolae to the cell surface, while cholesterol and glycosphingolipids drive caveolae scission from the PM. Whilst all three lipids accumulated specifically in caveolae, cholesterol and sphingomyelin were actively sequestered, whereas glycosphingolipids diffused freely. The ATPase EHD2 restricts lipid diffusion and counteracts lipid-induced scission. We propose that specific lipid accumulation in caveolae generates an intrinsically unstable domain prone to scission if not restrained by EHD2 at the caveolae neck. This work provides a mechanistic link between caveolae and their ability to sense the PM lipid composition. © 2020, Hubert et al.System neuroscience of motor cognition regarding the space beyond immediate reach mandates free, yet experimentally controlled movements. We present an experimental environment (Reach Cage) and a versatile visuo-haptic interaction system (MaCaQuE) for investigating goal-directed whole-body movements of unrestrained monkeys. Two rhesus monkeys conducted instructed walk-and-reach movements towards targets flexibly positioned in the cage. We tracked 3D multi-joint arm and head movements using markerless motion capture. click here Movements show small trial-to-trial variability despite being unrestrained. We wirelessly recorded 192 broad-band neural signals from three cortical sensorimotor areas simultaneously. Single unit activity is selective for different reach and walk-and-reach movements. Walk-and-reach targets could be decoded from premotor and parietal but not motor cortical activity during movement planning. The Reach Cage allows systems-level sensorimotor neuroscience studies with full-body movements in a configurable 3D spatial setting with unrestrained monkeys. We conclude that the primate frontoparietal network encodes reach goals beyond immediate reach during movement planning. © 2020, Berger et al.
