An evaporite sequence from ancient brine recorded in Bennu samples.

Evaporation or freezing of water-rich fluids with dilute concentrations of dissolved salts can produce brines, as observed in closed basins on Earth and detected by remote sensing on icy bodies in the outer Solar System. The mineralogical evolution of these brines is well understood in regard to terrestrial environments, but poorly constrained for extraterrestrial systems owing to a lack of direct sampling. Here we report the occurrence of salt minerals in samples of the asteroid (101955) Bennu returned by the OSIRIS-REx mission.

The Ronne Ice Shelf survived the last interglacial.

The fate of the West Antarctic Ice Sheet (WAIS) is the largest cause of uncertainty in long-term sea-level projections. In the last interglacial (LIG) around 125,000 years ago, data suggest that sea level was several metres higher than today, and required a significant contribution from Antarctic ice loss, with WAIS usually implicated. Antarctica and the Southern Ocean were warmer than today, by amounts comparable to those expected by 2100 under moderate to high future warming scenarios.

Bat genomes illuminate adaptations to viral tolerance and disease resistance.

Zoonoses are infectious diseases transmitted from animals to humans. Bats have been suggested to harbour more zoonotic viruses than any other mammalian order. Infections in bats are largely asymptomatic, indicating limited tissue-damaging inflammation and immunopathology.

Neural signatures of risk-taking adaptions across health, bipolar disorder, and lithium treatment.

Cognitive and neural mechanisms underlying bipolar disorder (BD) and its treatment are still poorly understood. Here we examined the role of adaptations in risk-taking using a reward-guided decision-making task. We recruited volunteers with high (n = 40) scores on the Mood Disorder Questionnaire, MDQ, suspected of high risk for bipolar disorder and those with low-risk scores (n = 37).

Convergent evidence for the temperature-dependent emergence of silicification in terrestrial plants.

Research on silicon (Si) biogeochemistry and its beneficial effects for plants has received significant attention over several decades, but the reasons for the emergence of high-Si plants remain unclear. Here, we combine experimentation, field studies and analysis of existing databases to test the role of temperature on the expression and emergence of silicification in terrestrial plants. We first show that Si is beneficial for rice under high temperature (40 °C), but harmful under low temperature (0 °C), whilst a 2 °C increase results in a 37% increase in leaf Si concentrations.

Single cell profiling of circulating autoreactive CD4 T cells from patients with autoimmune liver diseases suggests tissue imprinting.

Autoimmune liver diseases (AILD) involve dysregulated CD4 T cell responses against liver self-antigens, but how these autoreactive T cells relate to liver tissue pathology remains unclear. Here we perform single-cell transcriptomic and T cell receptor analyses of circulating, self-antigen-specific CD4 T cells from patients with AILD and identify a subset of liver-autoreactive CD4 T cells with a distinct B-helper transcriptional profile characterized by PD-1, TIGIT and HLA-DR expression. These cells share clonal relationships with expanded intrahepatic T cells and exhibit transcriptional signatures overlapping with tissue-resident T cells in chronically inflamed environments.

CODE-ACCORD: A Corpus of building regulatory data for rule generation towards automatic compliance checking.

Automatic Compliance Checking (ACC) within the Architecture, Engineering, and Construction (AEC) sector necessitates automating the interpretation of building regulations to achieve its full potential. Converting textual rules into machine-readable formats is challenging due to the complexities of natural language and the scarcity of resources for advanced Machine Learning (ML). Addressing these challenges, we introduce CODE-ACCORD, a dataset of 862 sentences from the building regulations of England and Finland.

Diffusion-driven transient hydrogenation in metal superhydrides at extreme conditions.

In recent years, metal hydride research has become one of the driving forces of the high-pressure community, as it is believed to hold the key to superconductivity close to ambient temperature. While numerous novel metal hydride compounds have been reported and extensively investigated for their superconducting properties, little attention has been focused on the atomic and electronic states of hydrogen, the main ingredient in these novel compounds. Here, we present combined H- and La-NMR data on lanthanum superhydrides, LaH, (x = 10.

[Total nasal reconstruction by folded forearm radial flap: Technical note].

Total nasal reconstruction represents a complex challenge, requiring restoration of all three anatomical planes while preserving respiratory function. This procedure has significant therapeutic, aesthetic, social and professional implications for patients. We share our academic experience of reconstruction using a folded microanastomosed radial forearm flap (FRFF) combined with a paramedian forehead flap, using the technique of F.

Evolution of different forearm flap designs in phalloplasty.

Phalloplasty is one of the most complex procedures in plastic surgery. The criteria for an ideal neophallus include an aesthetic and erogenous phallus that allows for sexual intercourse, with a functional neo-urethra enabling standing urination. The free forearm flap has become the gold standard for phallic reconstruction.

A Systematic Review and Meta-analysis of the Clinical Impact of Prophylactic Quinolones with Adjuvant Bacillus Calmette-Guérin Instillation for Non-muscle-invasive Bladder Cancer.

Background And Objective: Bacillus Calmette-Guérin (BCG) reduces disease recurrence and progression in intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). BCG-associated adverse events during instillations are common, leading to treatment cessation. Prophylactic use of quinolones in conjunction with BCG instillations is one approach for reducing BCG-associated adverse events.

MemScreen: A smartphone application for detection of mild cognitive impairment: A validation study: Smartphone App for MCI Detection.

Background And Objectives: Primary care is often the first point of contact for patients with cognitive complaints, making initial cognitive screening an essential step to avoid delays in diagnosing Alzheimer's disease (AD) at an early stage. We developed MemScreen, a self-administered smartphone application that assesses overall cognition and verbal memory, and evaluated its ability to detect mild cognitive impairment (MCI) in both general and clinical populations.

Methods: We conducted two validation cohort studies: (1) UK-based Whitehall II cohort study (13th wave, 2018-2022) involving a general population (MCI defined by poor performance on a global cognitive score), and (2) five French memory clinics involving patients without dementia (amnestic MCI defined by the Free and Cued Selective Reminding Test).

Contribution of rat insular cortex to stimulus-guided action.

Anticipating rewards is fundamental for decision-making. Animals often use cues to assess reward availability and to make predictions about future outcomes. The gustatory region of the insular cortex (IC), the so-called gustatory cortex, has a well-established role in the representation of predictive cues, such that IC neurons encode both a general form of outcome expectation as well as anticipatory outcome-specific knowledge.

New Artisse intrasaccular device for intracranial aneurysm treatment: short term clinical and angiographic result from the prospective registry INSPIRE-A.

Coronary Events After Transcatheter Aortic Valve Replacement: Insights From the France TAVI Registry.

Background: The prevalence of coronary artery disease in patients undergoing transcatheter aortic valve replacement (TAVR) is high. Treatment of a coronary events (CE) after TAVR can be technically challenging.

Objectives: The authors sought to assess the incidence and prognostic impact of CE after TAVR.

Multicentre, double-blind, randomised controlled clinical trial comparing intermittent cefoxitin administration versus loading bolus followed by continuous infusion for the prevention of surgical site infection in colorectal surgery: the PROPHYLOXITIN study protocol.

Introduction: Surgical site infections (SSIs) are the second leading cause of healthcare-associated infections in Europe with the highest rates being reported in colorectal surgery (ranging from 9% to 30%). Surgical antibiotic prophylaxis (SAP) is one of the most efficient measures for SSI prevention and should be started before surgical incision. Cefoxitin is an antibiotic widely used as SAP for colorectal surgery, but its continuous administration is currently the subject of debate due to its potential pharmacokinetic advantages.

Biodegradation study in FBS media of polycaprolactone patch as a potential prenatal treatment for myelomeningocele.

Myelomeningocele (MMC) is a congenital defect of the spine characterized by meningeal and spinal cord protrusion through open vertebral archs, and its exposure to the amniotic fluid. Given that the progression of neuronal loss begins early in fetal life, an early coverage of the defect is required to improve the neurological outcomes. Several studies have proposed patches as an alternative to full surgical repair, to achieve an early protection of the spine and possibly reduce the rate of complications of current prenatal surgical procedures.

Ex vivo electrophysiological evaluation of peripheral nerve functioning following exposition of adult mice to the organophosphorus pesticide chlormephos.

The organophosphorus pesticide chlormephos was tested for its potential peripheral neurotoxicity by analyzing the diphasic compound action potential (CAP) of sciatic nerves isolated from adult mice chronically exposed to a sub-lethal dose of this pesticide, compared with control age-matched animals being only exposed to the vehicle. No significant modification was detected between chlormephos-exposed and control groups in their nerve responsiveness to stimulus. Furthermore, similar values of CAP kinetic variables were obtained from the two mouse groups.
