Context.—: The diagnosis of pulmonary alveolar proteinosis (PAP) relies on a limited set of stains, namely hematoxylin-eosin and periodic acid-Schiff-diastase (PAS-D), demonstrating abundant alveolar material representing mostly surfactant. As cells harboring surfactant also express Napsin-A (pneumocytes and macrophages), we hypothesized that it would also be expressed within alveoli in PAP.

It is notable that monogenic forms of diabetes are exceedingly uncommon, with only 28 genes thus far identified. Such conditions frequently result in the dysfunction of pancreatic cells responsible for insulin production. Mutation in the TRMT10A gene leads to a rare genetic disease that is associated with endocrine and metabolic disorders, including diabetes and short stature.

This study aimed to provide a more complete characterization of microbial communities from preferential flow paths and matrix sediments of a clayey till to a depth of 400 cm by using 16S rRNA gene and fungal ITS2 amplicon sequencing of environmental DNA. Moreover, shotgun metagenomics was applied to samples from fractures located 150 cm below ground surface (bgs) to investigate the bacterial genomic adaptations resulting from fluctuating exposure to nutrients, oxygen and water.

GLP-1 (glucagon-like peptide-1) receptor agonists are a class of anti-diabetic agents that act by inducing insulin secretion and inhibiting glucagon release in a glucose-dependent manner. They are particularly promising because of their long duration of action, reduced risk of hypoglycaemia and the added benefit of weight loss. Trulicity ® dulaglutide is a GLP-1 receptor agonist approved for type II diabetes and chronic weight management in obese adults.

Penile prosthesis (PP) implantations are performed when other treatments are unsuccessful. However, there is no data regarding PP implantations in France beyond the year 2016.

This multicenter TRANSPLANT'AFUF study including 2,854 patients, transplanted between 1 January 2011, and 31 December 2022, investigated nighttime kidney transplantation's impact (8:00 p.m.

However, these sizes of MPs are mostly overlooked due to different analytical challenges; besides, their pathways through atmospheric depositions, such as snow depositions, are mostly unknown. The spatial variability in bulk snow samples was investigated for the first time in distinct sites (e.

Indeed, the outdoor atmosphere continuously receives large quantities of particles of biological origins, emitted from both anthropogenic or natural sources at the near Earth's surface. Nonetheless, our understanding of the composition of the atmospheric resistome, especially at mid-altitude (i.

Polycyclic Aromatic Hydrocarbons (PAHs) are environmental tracers of emission, transport and deposition processes. A first campaign has been conducted at Ny-Ålesund, Svalbard, from October 2018 to May 2019, monitoring weekly concentrations of PAHs in Arctic surface snow.

Duck and seabird migrations, for instance, play a key role in the spatial transmission dynamics and gene flow of avian influenza viruses (AIV), worldwide. On tropical islands, brown and lesser noddies ( and ) may be important AIV hosts, but the lack of knowledge on their migratory behaviour limits our understanding of virus circulation in island networks.

Materials And Methods: From the French national hospital database (PMSI-MCO), every hospitalization in French hospitals for renal tumor PN in 2016-2017 were extracted. Complications were documented from the initial hospitalization and any rehospitalization over two years.
Purpose: In France, transurethral resection of the prostate (TURP) is still the most commonly used surgical treatment for medium sized benign prostatic hyperplasia (BPH), but the Holmium Laser Enucleation of the Prostate (HoLEP) and laser vaporization procedures are becoming more common. For these three surgical procedures, we evaluate the initial complications, the short term (3 months) and the 4-12-month postoperative complications necessitating re-hospitalization.
Methods: From the French national hospital data base (PMSI-MCO), all hospitalizations for BPH treatment in 2018 were extracted.
Penile fracture is a urological emergency, and surgery is usually recommended to prevent complications. However, proximal locations are scarce and not well investigated. We present two rare penile fractures involving the proximal corpora cavernosa with an original conservative strategy to manage this clinical presentation.

Polar regions are increasingly exposed to ultraviolet light due to ozone depletion. Snowpacks contain photochemically active particles that, when irradiated, can lead to the production and accumulation of reactive species that can induce oxidative stress on snow microorganisms. This could generate a selective pressure on snowpack bacteria.

The main scientific and technological problems to address this are related to the storage and disposal of the nuclear waste and monitoring the dispersion of radioactive species into the environment. In this work, we determined an anomalously high C activity, well above the modern natural background, on surface and seasonal snow sampled in early May 2019 on glaciers in the Hornsund fjord area (Svalbard).

However, in winter, Arctic soils are isolated from outside sources other than snow, which is the sole source of microorganisms. Successful colonisation of soil by snow microorganisms depends on the ability to survive and compete of both, the invading and resident community.

Supraglacial microbes endure various environmental extremes including resource scarcity, frequent temperature fluctuations above and below the freezing point of water, and high UV irradiance during summer followed by months of total darkness during winter. One strategy that enables microbial life to persist through environmental extremes is dormancy, which despite being prevalent among microbial communities in natural settings, has not been directly measured and quantified in glacier surface ecosystems.

This could stimulate the development of antibiotic resistance in snow and its dissemination through the atmosphere and through snow melting. Despite these potential impacts, the effect of winter tourism on the snow antibiotic resistome remains to be elucidated.

In particular, samples that are low biomass, or that have to be collected and preserved in logistically challenging environments (such as remote sites or during long sampling campaigns) can pose exceptional difficulties. With this work, we compare and assess the effectiveness of three preservation methods for DNA and RNA extracted from microbial communities of glacial snow and ice samples.

Antibiotic resistance is a growing public health threat that complicates the treatment of infections. β-Lactamase enzymes, which hydrolyze the β-lactam ring present in many common antibiotics, are a major cause of this resistance and are produced by a broad range of bacterial pathogens. Here, we developed hydrogels that degrade specifically in the presence of β-lactamases and β-lactamase-producing bacteria as a platform for bacteria-triggered drug delivery.
