Cognitive impairments after maximal repeated breath-holding in elite breath-hold divers.

Background: Breath-hold (BH) training over several years may result in mild but persistent neurocognitive impairment. Paradoxically, the acute effects of repeated BH generating intermittent hypoxia on neurocognitive functions are still poorly understood. Therefore, we decided to examine the impact of five-repeated maximal BH on attention, processing speed, and reasoning abilities.

Spatio-temporal distribution and genetic background of elastic proteins inside the chitin/chitosan matrix of insects including their functional significance for locomotion.

In insects, cuticle proteins interact with chitin and chitosan of the exoskeleton forming crystalline, amorphic or composite material structures. The biochemical and mechanical composition of the structure defines the cuticle's physical properties and thus how the insect cuticle behaves under mechanical stress. The tissue-specific ratio between chitin and chitosan and its pattern of deacetylation are recognized and interpreted by cuticle proteins depending on their local position in the body.

Is the lactate value predictive of the return of spontaneous circulation during CPR in nontraumatic OHCA?

Aim Of The Study: Cardiac arrest is a major public health issue, in which emergency medical services (EMS) initiating or continuing resuscitation in about 50% to 60% of cases. The aim of this study was to determine whether blood lactate levels and their course during cardiopulmonary resuscitation are prognostic indicators of the return of spontaneous cardiac activity (ROSC) in non-traumatic out-of-hospital cardiac arrest (OHCA).

Methods: This was a prospective, interventional, multi-center study between 2017 and 2020.

Endoscopic Administration of Combined Autologous Mesenchymal Stem Cells and Platelet-Rich Plasma for the Treatment of Gastric Staple Line Leaks After Sleeve Gastrectomy.

Background: Gastric staple line leak treatment after laparoscopic sleeve gastrectomy (LSG) remains challenging. Regenerative medicine is gaining place in the accelerated treatment of damaged tissues. This study presents the first series of gastric leak treatment after LSG using endoscopic intragastric administration of combined autologous mesenchymal stem cells (MSC) and platelet-rich plasma (PRP).

Cooperative cell-cell actin network remodeling to perform Gap junction endocytosis.

Background: The endocytosis of Gap junction plaques (GJP) requires cytoskeletal forces to internalize such large membranous structures. Actin, which partners the connexin proteins constituting Gap junctions and is located close to Annular Gap Junctions (AGJ), could be actively involved in this physiological process.

Results: Electron Microscopy and Light Microscopy images, associated with time-lapse analysis and 3D reconstruction, used at high resolution and enhanced using ImageJ based software analysis, revealed that: i) actin cables, originating from Donor cells, insert on the edge of GJP and contribute to their invagination, giving rise to AGJ, whereas actin cables on the Acceptor cell side of the plaque are not modified; ii) actin cables from the Donor cell are continuous with the actin network present over the entire GJP surface.

The Radius of Curvature of the Inferior Distal Clavicle Is Similar to That of the Glenoid in Both the Axial and Coronal Planes and Similar to the Inferior Coracoid.

Purpose: The purposes of this study were to use computed tomography (CT) scans to compare the radius of curvature (ROC) of the inferior concave surface of the distal clavicle to the glenoid, determine graft dimensions, and compare the ROC of the congruent-arc distal clavicle autograft (DCA) to the congruent-arc Latarjet graft.

Methods: Patients who underwent bony glenoid reconstruction via a Laterjet procedure between January 2018 and January 2023 at a single institution were retrospectively identified. CT scans were used to measure the ROC of the glenoid on the axial and coronal sequences, measure the ROC of the distal clavicle on the sagittal oblique sequences, and determine the dimensions of the distal clavicle and coracoid graft.

Background: While the benefits of robotic assistance were established at the beginning of surgical training, there is limited data on the robot's influence on experienced bariatric laparoscopic surgeons.

Methods: We conducted a retrospective study using the BRO clinical database (2008-2022) collecting data of patients operated on in expert centers.

The discrimination of expressions in facial movements by infants: A study with point-light displays.

Perceiving facial expressions is an essential ability for infants. Although previous studies indicated that infants could perceive emotion from expressive facial movements, the developmental change of this ability remains largely unknown. To exclusively examine infants' processing of facial movements, we used point-light displays (PLDs) to present emotionally expressive facial movements.

Laparoscopic Roux-en-Y fistulojejunostomy as a salvage procedure in patients with chronic gastric leak after sleeve gastrectomy.

Background: The most common postoperative complication of laparoscopic sleeve gastrectomy (LSG) is staple-line leak. Even if its rate following LSG has been recently reduced, management of chronic leaks remains challenging.

Objective: To present a series of patients treated with laparoscopic Roux-en-Y fistulojejunostomy (LRYFJ) for chronic gastric leak (>12 wk) post-LSG.

Relevance of Teledentistry: Brief Report and Future Perspectives.

Teledentistry is a type of telemedicine and telehealth that aims to make all major specialties of the discipline easier through a remote approach to prevention and treatment of oral and dental issues. This new method enables distant access to individuals instead of direct, face-to-face, doctor-patient contact and has been made possible thanks to developments in information technology. Teledentistry was described in 1997 as "… the practice of using video-conferencing technologies to diagnose and provide advice about treatment over a distance", and today it represents a modern way to practice dentistry by integrating digital imaging, electronics, health records, and telecommunications technology via an internet connection.

Quality assessment in light microscopy for routine use through simple tools and robust metrics.

Although there is a need to demonstrate reproducibility in light microscopy acquisitions, the lack of standardized guidelines monitoring microscope health status over time has so far impaired the widespread use of quality control (QC) measurements. As scientists from 10 imaging core facilities who encounter various types of projects, we provide affordable hardware and open source software tools, rigorous protocols, and define reference values to assess QC metrics for the most common fluorescence light microscopy modalities. Seven protocols specify metrics on the microscope resolution, field illumination flatness, chromatic aberrations, illumination power stability, stage drift, positioning repeatability, and spatial-temporal noise of camera sensors.

Identification of Human Breast Adipose Tissue Progenitors Displaying Distinct Differentiation Potentials and Interactions with Cancer Cells.

Breast adipose tissue (AT) participates in the physiological evolution and remodeling of the mammary gland due to its high plasticity. It is also a favorable microenvironment for breast cancer progression. However, information on the properties of human breast adipose progenitor cells (APCs) involved in breast physiology or pathology is scant.

Impact of a phone call with a medical student/general practitioner team on morbidity of chronic patients during the first French COVID-19 lockdown (COVIQuest): a cluster randomised trial.

Objectives: The first COVID-19 lockdown led to a significantly reduced access to healthcare, which may have increased decompensations in frail patients with chronic diseases, especially older patients living with a chronic cardiovascular disease (CVD) or a mental health disorder (MHD). The objective of COVIQuest was to evaluate whether a general practitioner (GP)-initiated phone call to patients with CVD and MHD during the COVID-19 lockdown could reduce the number of hospitalisation(s) over a 1-month period.

Design: This is a cluster randomised controlled trial.
