Accurate and robust anatomical landmark localization is a mandatory and crucial step in deformation diagnosis and treatment planning for patients with craniomaxillofacial (CMF) malformations. In this paper, we propose a trainable end-to-end cephalometric landmark localization framework on Cone-beam computed tomography (CBCT) scans, referred to as CMF-Net, which combines the appearance with transformers, geometric constraint, and adaptive wing (AWing) loss. More precisely: (1) we decompose the localization task into two branches: the appearance branch integrates transformers for identifying the exact positions of candidates, while the geometric constraint branch at low resolution allows the implicit spatial relationships to be effectively learned on the reduced training data.

The rod-shaped adult cardiomyocyte (CM) harbors a unique architecture of its lateral surface with periodic crests, relying on the presence of subsarcolemmal mitochondria (SSM) with unknown role. Here, we investigated the development and functional role of CM crests during the postnatal period. We found in rodents that CM crest maturation occurs late between postnatal day 20 (P20) and P60 through both SSM biogenesis, swelling and crest-crest lateral interactions between adjacent CM, promoting tissue compaction.

Drivers of Perceived Nuisance Growth by Aquatic Plants.

Environ Manage

May 2023

Faculty of Environmental Sciences and Natural Resource Management, Norwegian University of Life Sciences, P.O. Box 5003, 1430, Ås, Norway.

Mass developments of macrophytes occur frequently worldwide and are often considered a nuisance when interfering with human activities. It is crucial to understand the drivers of this perception if we are to develop effective management strategies for ecosystems with macrophyte mass developments. Using a comprehensive survey spanning five sites with different macrophyte species in four countries (Norway, France, Germany and South Africa), we quantified the perception of macrophyte growth as a nuisance among residents and visitors, and for different recreational activities (swimming, boating, angling, appreciation of biodiversity, appreciation of landscape and birdwatching).

Sexual selection in females and the evolution of polyandry.

PLoS Biol

January 2023

CEFE, Univ Montpellier, CNRS, EPHE, IRD, Montpellier, France.

Article Synopsis
  • The perception of sexual selection has shifted from viewing males as eager and females as coy to recognizing that both genders can benefit from multiple mating opportunities.
  • Research shows that female reproductive success is positively correlated with mating success, indicating that females also gain fitness from mating with multiple partners.
  • This evidence supports the idea that sexual selection is significant in females and is important for understanding the evolution of various animal mating systems.

Metal Organic Framework Glasses: A New Platform for Electrocatalysis?

Chem Rec

June 2023

School of Materials Science and Engineering, Wuhan University of Technology, Wuhan, 430070, Hubei, China.

Metal organic framework (MOF) glasses are a coordination network of metal nodes and organic ligands as an undercooled frozen-in liquid, and have therefore broadened the potential of MOF materials in the fundamental research and application scenarios. On the road to deploying MOF glasses as electrocatalysts, it remains several basic scientific hurdles although MOF glasses not only inherit the structural merits of MOFs but also endow with active catalytic features including concentrated defects, metal centers and disorder structure etc. The research on the ionic conductivity, catalytic stability and reactivity of MOF glasses has yielded scientific insights towards its electrocatalytic applications.

Reference Probe for TcpO at Rest: A Systematic Review.

Diagnostics (Basel)

December 2022

Service de Médecine Interne et Vasculaire, Hôpital Edouard Herriot, Hospices Civils de Lyon, 69003 Lyon, France.

(1) Background: Transcutaneous oxygen pressure (TcpO) is used to determine the severity of lower extremity arterial disease (LEAD). Many authors used a ratio of limb to chest TcpO, also called the regional perfusion index (RPI), which should be independent of variations in oxygen delivery and reflective of local limb oxygen supply. The relevance of a reference probe-positioned TcpO electrode is debated.

Université de Rennes 1, UMR CNRS 6553, Ecosystèmes-Biodiversité-Evolution, OSUR, Campus de Beaulieu, Bâtiment 14A, 35042, Rennes Cedex, France.

Article Synopsis
  • - Environmental contamination by substances called xenobiotics poses significant risks to ecosystems and human health, making it crucial for organisms to develop detoxification mechanisms to handle these stressors.
  • - In this study, researchers investigated how allopolyploidy affects the ability of Spartina plants to tolerate xenobiotics, focusing on the role of microRNAs (miRNAs) that regulate gene expression during stress responses.
  • - The findings revealed 17 specific miRNAs that respond to stress from phenanthrene exposure, highlighting differences in miRNA expression between hybrid and parent species, and indicating that allopolyploidy influences these regulatory networks in Spartina compared to other plants like Arabidopsis.

Metal-organic frameworks are a class of porous solids that exhibit intriguing flexibility under stimuli, leading often to reversible giant structural changes upon guest adsorption. DUT-49(Cu) and MIL-53(Cr) are fascinating flexible MOFs owing to their guest-induced breathing and negative gas adsorption behaviors respectively. Molecular simulation is one of the most relevant tools to examine these phenomena at the atomistic scale and gain a unique understanding of the physics behind them.

CD95L (also known as FasL or CD178) is a member of the tumor necrosis family (TNF) superfamily. Although this transmembrane ligand has been mainly considered as a potent apoptotic inducer in CD95 (Fas)-expressing cells, more recent studies pointed out its role in the implementation of non-apoptotic signals. Accordingly, this ligand has been associated with the aggravation of inflammation in different auto-immune disorders and in the metastatic occurrence in different cancers.

The use of stable-isotope probing (SIP) allows tracing specific labeled substrates into fungi leading to a better understanding of their role in biogeochemical cycles and their relationship with their environment. Stable isotope probing combined with ribosomal RNA molecule, conserved in the three kingdoms of life, and messenger RNA analysis permits the linkage of diversity and function. Here, we describe two methods designed to investigate the interactions between plants and their associated mycorrhizal compartment by tracing carbon flux from the host plant to its symbionts.

High Verdet Constant Glass for Magnetic Field Sensors.

ACS Appl Mater Interfaces

December 2022

State Key Laboratory of Silicate Materials for Architectures, Wuhan University of Technology, Wuhan 430070, China.

Due to the high transparency, high Verdet constant, as well as easy processing properties, rare-earth ion-doped glasses have demonstrated great potential in magneto-optical (MO) applications. However, the variation in the valence state of rare-earth ions (Tb to Tb) resulted in the decreased effective concentration of the paramagnetic ions and thus degraded MO performance. Here, a strategy was proposed to inhibit the oxidation of Tb into Tb as well as improve the thermal stability by tuning the optical basicity of glass networks.

Univ Rennes, CHU Rennes, Inserm, EHESP, Irset (Institut de recherche en santé, environnement et travail) - UMR_S 1085, Rennes, F-35000, France.

These clinical practice guidelines from the French National College of Midwives (CNSF) are intended to define the messages and the preventive interventions to be provided to women and co-parents by the different professionals providing care to women or their children during the perinatal period. These guidelines are divided into 10 sections, corresponding to 4 themes: 1/ the adaptation of maternal behaviors (physical activity, psychoactive agents); 2/ dietary behaviors; 3/ household exposure to toxic substances (household uses, cosmetics); 4/ promotion of child health (breastfeeding, attachment and bonding, screen use, sudden unexplained infant death, and shaken baby syndrome). We suggest a ranking to prioritize the different preventive messages for each period, to take into account professionals' time constraints.
