Unveiling of Hydrogen Spillover Mechanisms on Tungsten Oxide Surfaces.

Hydrogen spillover is an important process in catalytic hydrogenation reactions, facilitating H activation and modulating surface chemistry of reducible oxide catalysts. This study focuses on the unveiling of platinum-induced hydrogen spillover on monoclinic tungsten trioxide (γ-WO), employing ambient pressure X-ray photoelectron spectroscopy, density functional theory calculations and microkinetic modeling to investigate the dynamic evolution of surface states at varied temperatures. At room temperature, hydrogen spillover results in the formation of W and hydrogen intermediates (hydroxyl species and adsorbed water), facilitated by Pt metal clusters.

Intraoperative iatrogenic type B aortic dissection. Temporary perfusion pause, immediate restoration and final solution.

We present the case of a 74-year-old female patient with a 50 mm ascending aortic aneurysm who underwent ascending aorta replacement. During routine open heart surgery, suboptimal flow in the cardiopulmonary bypass circuit, led to the discovery of a type B aortic dissection with substantial flow in the false lumen. Conservative management was chosen, focusing on blood pressure control in the ICU.

5-HT agonism as a neurotherapeutic for sarcopenia: preclinical proof of concept.

Sarcopenia, the pathological age-related loss of muscle mass and strength, contributes to physical decline, frailty, and diminished healthspan. The impact of sarcopenia is expected to rise as the aging population grows, and treatments remain limited. Therefore, novel approaches for enhancing physical function and strength in older adults are desperately needed.

Inflammatory biomarkers profiles and cognition among older adults.

Inflammation plays a major role in cognitive aging. Most studies on peripheral inflammation and cognitive aging focused on selected major inflammatory biomarkers. However, inflammatory markers are regulated and influenced by each other, and it is therefore important to consider a more comprehensive panel of markers to better capture diverse immune pathways and characterize the overall inflammatory profile of individuals.

Analyzing the relationship between gene expression and phenotype in space-flown mice using a causal inference machine learning ensemble.

Spaceflight has several detrimental effects on human and rodent health. For example, liver dysfunction is a common phenotype observed in space-flown rodents, and this dysfunction is partially reflected in transcriptomic changes. Studies linking transcriptomics with liver dysfunction rely on tools which exploit correlation, but these tools make no attempt to disambiguate true correlations from spurious ones.

Influence of edentulous areas on the accuracy of the maximum intercuspal position recorded by using different intraoral scanners or an artificial intelligence-based program.

Statement Of Problem: Intraoral scans can be articulated in maximum intercuspal position (MIP) by using an artificial intelligence (AI) based program; however, the impact of edentulous areas on the accuracy of the MIP located using this AI-based program is unknown.

Purpose: The purpose of this in vitro study was to assess the impact of edentulous areas (0, 1, 2, 3, and 4 posterior mandibular teeth) on the accuracy of the MIP located using 3 intraoral scanners (IOSs) and an AI-based program.

Material And Methods: Stone casts articulated in MIP in an articulator were digitized (T710).

LSD600: the first corpus of biomedical abstracts annotated with lifestyle-disease relations.

Lifestyle factors (LSFs) are increasingly recognized as instrumental in both the development and control of diseases. Despite their importance, there is a lack of methods to extract relations between LSFs and diseases from the literature, a step necessary to consolidate the currently available knowledge into a structured form. As simple co-occurrence-based relation extraction (RE) approaches are unable to distinguish between the different types of LSF-disease relations, context-aware models such as transformers are required to extract and classify these relations into specific relation types.

Understanding the Etiology of Externalizing Problems in Young Children: The Roles of Callous-Unemotional Traits and Irritability.

Objective: Callous-unemotional traits (CU), characterized as a lack of guilt and empathy; and irritability, a tendency to show anger and frustration; are 2 risk factors for externalizing behavioral problems. Externalizing problems, CU and irritability are all heritable. However, there is a dearth of studies examining the genetic and environmental associations between the 3 domains.

Outcomes of acute pericarditis with an inflammatory phenotype.

Background: Patients with pericarditis may show elevation of C-reactive protein (CRP) and pericardial effusion at presentation. There are limited data on the prognostic implications of this inflammatory phenotype.

Objectives: Aim of the present study is to evaluate the outcome of the inflammatory phenotype in a cohort of patients with acute pericarditis.

Digital Frequency Customized Relieving Sound for Chronic Subjective Tinnitus Management: Prospective Controlled Study.

Background: Tinnitus is a major health issue, but currently no tinnitus elimination treatments exist for chronic subjective tinnitus. Acoustic therapy, especially personalized acoustic therapy, plays an increasingly important role in tinnitus treatment. With the application of smartphones, personalized acoustic stimulation combined with smartphone apps will be more conducive to the individualized treatment and management of patients with tinnitus.

High-resolution isotope dietary analysis of Mesolithic and Neolithic humans from Franchthi Cave, Greece.

Franchthi Cave, in the Greek Peloponnese, is a well-known Paleolithic, Mesolithic and Neolithic site, with several human burials. In many parts of Europe there is clear evidence from archaeological and isotopic studies for a diet change between the Mesolithic and Neolithic periods. This is especially the case in coastal contexts where there is often a shift from predominantly marine food diets in the Mesolithic to terrestrial (presumably domesticated) foods in the Neolithic.

Lack of context modulation in human single neuron responses in the medial temporal lobe.

In subjects implanted with intracranial electrodes, we use two different stories involving the same person (or place) to evaluate whether and to what extent context modulates human single-neuron responses. Nearly all neurons (97% during encoding and 100% during recall) initially responding to a person/place do not modulate their response with context. Likewise, nearly none (<1%) of the initially non-responsive neurons show conjunctive coding, responding to particular persons/places in a particular context during the tasks.

Carcinosarcoma of the breast: Facing the challenge of a rare nosologic entity.

Carcinosarcoma (CS), also known as metaplastic breast carcinoma with mesenchymal differentiation, is one of the five distinct subtypes of metaplastic breast cancer. It is considered as a mixed, biphasic neoplasm consisting of a carcinomatous component combined with a malignant nonepithelial element of mesenchymal origin without an intermediate transition zone. Although cellular origin of this neoplasm remains controversial, most researchers declare that neoplastic cells derive from a cellular structure with potential biphasic differentiation.

Extracellular vesicles: from intracellular trafficking molecules to fully fortified delivery vehicles for cancer therapeutics.

Extracellular vesicles (EVs) are emerging as viable tools in cancer treatment due to their ability to carry a wide range of theranostic activities. This review summarizes different forms of EVs such as exosomes, microvesicles, apoptotic bodies, and oncosomes. It also sheds the light onto isolation methodologies, characterization techniques and therapeutic applications of all discussed EVs.

"Nip and Tuck": Training the Next Generation of Aesthetic Plastic Surgeons.

The demand for aesthetic surgery continues to increase, and it is therefore essential to ensure that the next generation of plastic surgeons are adequately trained. We propose a safe method in aesthetic training in abdominoplasty and facelift, utilizing free deep inferior epigastric perforator (DIEP) flap and parotidectomy for training aesthetic procedures. The trainees' focus differed between the 2 procedures.

Anatomic and Functional Reconstruction of the Abdominal Wall in Prune Belly Syndrome: A Case Report.

Prune belly syndrome (PBS), or Eagle-Barrett syndrome, is a rare congenital disorder marked by abdominal wall muscle deficiency, urinary tract anomalies, and cryptorchidism, causing significant abdominal wall laxity and functional impairment. This case report discusses an innovative approach to abdominal wall reconstruction in a 19-year-old male patient with PBS and associated conditions, including chronic renal failure and spina bifida. Previously, he underwent distal ureterectomy and vesicoureteral reimplantation at the age of two years to correct urinary tract dilation and bilateral orchiopexy.

Does stereoscopic immersive virtual reality have a significant impact on anatomy education? A literature review.

Purpose: Stereoscopic immersive virtual reality (SIVR) is a technology that fully immerses the user in a digital environment and permits the perception of two different three-dimensional images of a digital object with each of the two eyes. We conducted a literature review to explore to what extent SIVR can significantly contribute to anatomy education.

Methods: We searched PubMed, Scopus, ERIC, and the Cochrane Library for papers investigating the outcomes (effectiveness, perceptions about effectiveness, and side effects) of implementing SIVR in anatomy education.

Skin cancer treatment environment and survivorship resources among sexual and gender minority patients: results of the OUT National Cancer Survey.

Sexual and gender minority (SGM) cancer survivors face unmet care needs in accessing cancer health information and social support despite high satisfaction with treatment. SGM patients often delay care due to concerns of discrimination in healthcare settings, though the care experiences of SGM skin cancer survivors are less known. SGM individuals, particularly sexual minority men, report higher skin cancer prevalence and related risk behaviors than heterosexual men.

Running trends in Switzerland from 1999 to 2019: An exploratory observational study.

Background: Several single race events (5 km, 10 km, half-marathon, marathon, ultra-marathon) in different countries and different years have been analyzed in multiple studies, representing the rising interest in endurance-based activity and thus physical health. With focus on participation numbers, performance or sex difference, many single study results were obtained. The running trends in a whole country covering a longer period of time and several race distances are missing so far.
