Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Ann Endocrinol (Paris)

January 2025

Internal Medicine, Diabetes and Metabolic Disorders, University Hospitals of Strasbourg, Strasbourg University, Strasbourg, France.

Treatment modalities for primary hyperparathyroidism must take account of the expected benefits and risks of each treatment envisaged, before choosing the definitive option to be proposed to the patient. In this section, a Foreword puts in perspective the difficulties involved in choosing the criteria for a particular treatment method. Treatments are then considered one after the other: surgery, local destruction and medical management.

[Management of a fetus suspected of differences of sex development (DSD).].

Gynecol Obstet Fertil Senol

January 2025

Department of Obstetrics and Gynaecology, Hôpital Saint Joseph, Marseille, France; Image2 center, Marseille, France. Electronic address:

The management of a fetus suspected of having a variation in genital development is a complex situation. In cases of complete discordance or an unusual appearance of the external genitalia (EG), management always begins with a diagnostic morphological ultrasound. This ultrasound aims to provide detailed imaging of the EG and internal genitalia (IG), focusing on identifying the presence of Müllerian derivatives and detecting any associated malformations.

Magnetotactic bacteria affiliated with diverse Pseudomonadota families biomineralize intracellular Ca-carbonate.

ISME J

January 2025

Aix-Marseille Université, CNRS, CEA, BIAM, UMR7265 Institut de Biosciences and Biotechnologies d'Aix-Marseille, Cadarache research centre, F-13115 Saint-Paul-lez-Durance, France.

Intracellular calcium carbonate formation has long been associated with a single genus of giant Gammaproteobacteria, Achromatium. However, this biomineralization has recently received increasing attention after being observed in photosynthetic Cyanobacteriota and in two families of magnetotactic bacteria affiliated with the Alphaproteobacteria. In the latter group, bacteria form not only intracellular amorphous calcium carbonates into large inclusions that are refringent under the light microscope, but also intracellular ferrimagnetic crystals into organelles called magnetosomes.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Purpose: Immune Checkpoints Inhibitors (ICI) have changed the therapeutic landscape of metastatic renal cell carcinoma first-line treatment with complete response (CR) at metastatic sites observed in 10 to 15% of cases. Delayed nephrectomy could be discussed for patients having a clinical benefit from immunotherapy-based treatment. However, it is unclear whether prior immunotherapy exposure adversely influences the complexity of surgery.

Massive material injections in the JET tokamak have been observed to substantially affect resistive bolometer measurements, resulting in a spurious radiated power signal proportional to the quantity injected and reaching up to 8 MW. These bolometers are calibrated and designed to operate in near vacuum but certain scenarios requiring large gas injections can push the neutral pressure past nominal values. This study demonstrates that the bolometry measurement can be affected at neutral pressures above 0.

In the search for new antituberculosis drugs with novel mechanisms of action, we evaluated the antimycobacterial activity of a panel of eight phenolic acids against four pathogenic mycobacterial model species, including Mycobacterium tuberculosis. We demonstrated that salicylic acid (SA), as well as the iodinated derivatives 5-iodo-salicylic acid (5ISA) and 3,5-diiodo-salicylic acid (3,5diISA), displayed promising antitubercular activities. Remarkably, using a genetically encoded mycobacterial intrabacterial pH reporter, we describe for the first time that SA, 5ISA, 3,5diISA, and the anti-inflammatory drug aspirin (ASP) act by disrupting the intrabacterial pH homeostasis of M.
