A rare complication of a thoracic wound: the pneumopericardium?

Pneumopericardium (PPC) is defined by the presence of gas in the pericardial cavity, often leading to cardiac tamponade and a high mortality rate. This report describes a case involving a 33-year-old man found deceased a few meters from a knife, his clothes intact, with no resuscitation attempt made. A knotted scarf was tightly fastened around his neck, without ligature mark.

Eco-Friendly Extraction of Phlorotannins from : Identification Related to Purification Methods Towards Innovative Cosmetic Applications.

This study focuses on developing innovative and eco-friendly purification methods for the isolation of bioactive compounds derived from , a brown abundant macroalga in Djibouti. Three distinct fractions, obtained via liquid-liquid extraction (LLE_FAE), solid-phase extraction (SPE_WE50), and flash chromatography (FC_EtOH20), were selected based on their high phenolic content and antioxidant activities. All fractions were also evaluated for their anti-ageing potential by assessing their ability to inhibit two vital skin-ageing enzymes, tyrosinase and elastase.

Investigating assumptions in motivational interviewing among general practitioners: a qualitative study.

Background: Unhealthy behaviours contributing to cardiovascular issues, diabetes, strokes, and cancer, pose significant health risks. General practitioners (GPs) are pivotal in guiding behaviour change, with Motivational Interviewing (MI) showing promise. MI, developed by William Miller and Stephen Rollnick, aims to enhance motivation for change.

Optimized assessment of physical rehabilitation exercises using spatiotemporal, sequential graph-convolutional networks.

Rehabilitation is the process of helping people regain or improve lost or impaired function due to injury, illness, or disease. To assist in tracking the progress of patients undergoing rehabilitation, this paper proposes a lightweight graph-based deep-learning model for the automatic assessment of physical rehabilitation exercises. The model takes as input the 3D skeleton sequence of a patient performing a movement and outputs a continuous quality score, as a means for patient supervision that could complement or even substitute the need for ordinary clinical exams.

Anti-Obesity Effects Evaluation of a Blackcurrant Leaf Standardized Hydro-Alcoholic Extract in Wistar Rat Subjected to a High-Fat Diet.

Blackcurrant (BC) extract was reported to exert anti-obesity effects. However, it is unknown whether BC extract with a composition close to the totum differentially affects obesity when compared to one of its active compounds. We evaluated the anti-obesity effects of a BC standardized hydro-alcoholic leaf extract (BC-HLE) in an HFD-induced obesity rat model and compared them with quercetin (QUE).

A templex-based study of the Atlantic Meridional Overturning Circulation dynamics in idealized chaotic models.

Significant changes in a system's dynamics can be understood through modifications in the topological structure of its flow in phase space. In the Earth's climate system, such changes are often referred to as tipping points. One of the large-scale components that may pass a tipping point is the Atlantic Meridional Overturning Circulation.

Energy-Resolved Mass Spectrometry and Mid-Infrared Spectroscopy for Purity Assessment of a Synthetic Peptide Cyclised by Intramolecular Huisgen Click Chemistry.

Cyclic peptides have higher stability and better properties as therapeutic agents than their linear peptide analogues. Consequently, intramolecular click chemistry is becoming an increasingly popular method for the synthesis of cyclic peptides from their isomeric linear peptides. However, assessing the purity of these cyclic peptides by mass spectrometry is a significant challenge, as the linear and cyclic peptides have identical masses.

Active disturbance rejection control for four-wire inverters in standalone renewable resources-based microgrid - islanded microgrids ADRC-based control.

This paper presents an active disturbance rejection control (ADRC) approach for three-phase four-legs voltage source inverters (FL-VSIs) in a standalone renewable energy resources (RES)-based islanded microgrid. The key purpose of the proposed approach is to improve the control robustness against load-side disturbances, power supply parameters uncertainties, and faulty operating conditions. Indeed, a notable benefit of ADRC is its ability to operate effectively without the need for precise knowledge of disturbance characteristics or accurate modeling and FL-VSI parameters.

Bimodal PET/MRI generative reconstruction based on VAE architectures.

In this study, we explore positron emission tomography (PET)/magnetic resonance imaging (MRI) joint reconstruction within a deep learning framework, introducing a novel synergistic method.We propose a new approach based on a variational autoencoder (VAE) constraint combined with the alternating direction method of multipliers (ADMM) optimization technique. We explore three VAE architectures, joint VAE, product of experts-VAE and multimodal JS divergence (MMJSD), to determine the optimal latent representation for the two modalities.

Potential of Marine Sponge Metabolites against Prions: Bromotyrosine Derivatives, a Family of Interest.

The screening of 166 extracts from tropical marine organisms (invertebrates, macroalgae) and 3 cyclolipopeptides from microorganisms against yeast prions highlighted the potential of Verongiida sponges to prevent the propagation of prions. We isolated the known compounds purealidin Q (), aplysamine-2 (), pseudoceratinine A (), aerophobin-2 (), aplysamine-1 (), and pseudoceratinine B () for the first time from the Wallisian sponge . We then tested compounds - and sixteen other bromotyrosine and bromophenol derivatives previously isolated from Verongiida sponges against yeast prions, demonstrating the potential of -, , , aplyzanzine C (), purealidin A (), psammaplysenes D () and F (), anomoian F (), and N,N-dimethyldibromotyramine ().

A Review on Low-Dose Emission Tomography Post-Reconstruction Denoising with Neural Network Approaches.

Low-dose emission tomography (ET) plays a crucial role in medical imaging, enabling the acquisition of functional information for various biological processes while minimizing the patient dose. However, the inherent randomness in the photon counting process is a source of noise which is amplified low-dose ET. This review article provides an overview of existing post-processing techniques, with an emphasis on deep neural network (NN) approaches.

Scintillation in Liquid Xenon for Gamma-Ray Medical Imaging: From Single Time-over-Threshold to Multi-Time-over-Threshold PMT Signal Measurements.

In this paper, a new light event acquisition chain in a three-gamma liquid xenon prototype for medical nuclear imaging is presented. The prototype implements the Multi-Time-Over-Threshold (MTOT) method. This method surpasses the Single-Time-Over-Threshold (STOT) by precisely determining both the number of vacuum ultraviolet (VUV) photons detected by each photomultiplier tube (PMT) and their arrival times for light signal measurement.

[The benefits of socio-aesthetics in psychiatry: three experiments with adolescents].

Adolescents and young adults admitted to the Espace unit at Nantes University Hospital are offered beauty treatments. Although their situations are diverse, they consistently show a decline in self-esteem. These young patients benefit from individual hand and facial treatments, make-up sessions and group workshops.

A dataset of acoustic measurements from soundscapes collected worldwide during the COVID-19 pandemic.

Political responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium of 261 contributors from 35 countries brought together by the Silent Cities project built a unique soundscape recordings collection to report on local acoustic changes in urban areas. We present this collection here, along with metadata including observational descriptions of the local areas from the contributors, open-source environmental data, open-source confinement levels and calculation of acoustic descriptors.

Economic analysis of digital motor rehabilitation technologies: a systematic review.

Rehabilitation technologies offer promising opportunities for interventions for patients with motor disabilities. However, their use in routine care remains limited due to their high cost and persistent doubts about their cost-effectiveness. Providing solid evidence of the economic efficiency of rehabilitation technologies would help dispel these doubts in order to better take advantage of these technologies.

Taming 2,2'-biimidazole ligands in trivalent chromium complexes.

Complete or partial replacement of well-known five-membered chelating 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) ligands with analogous didentate 2,2'-biimidazole (Hbiim) provides novel perspectives for exploiting the latter pH-tuneable bridging unit for connecting inert trivalent chromium with cationic partners. The most simple homoleptic complex [Cr(Hbiim)] and its stepwise deprotonated analogues are only poorly soluble in most solvents and their characterization is limited to some solid-state structures, in which the pseudo-octahedral [CrN] units are found to be intermolecularly connected peripheral N-H⋯X hydrogen bonds. Moreover, the associated high-energy stretching N-H vibrations drastically quench the targeted near infrared (NIR) Cr-based phosphorescence, which makes these homoleptic building blocks incompatible with the design of molecular-based luminescent assemblies.
