Chemical process of hydrogen and formic acid on a Pd-deposited Cu(111) surface studied by high-resolution X-ray photoelectron spectroscopy and density functional theory calculations.

Formic acid (HCOOH) is one of the essential molecules for CO utilization including methanol synthesis and hydrogen carriers. In this study, we have investigated the chemical processes of hydrogen and HCOOH on a dilute-alloy Pd-Cu(111) surface using high-resolution X-ray photoelectron spectroscopy (HR-XPS) and density functional theory (DFT) calculations. The present Pd-Cu(111) surface was prepared at 500 K, and the observed core-level shifts of Pd 3d indicate that Pd atoms were located at the surface and subsurface sites: 335.

Comparison of sedation with pentazocine or pethidine hydrochloride for endoscopic ultrasonography in outpatients: A single-center retrospective study.

Objectives: Endoscopic ultrasonography (EUS) plays an important role in the diagnosis of pancreatobiliary diseases. However, an appropriate sedation method for EUS has not been established. Therefore, this study aimed to examine the safety and complications of sedation with pentazocine or pethidine hydrochloride for outpatient diagnostic EUS.

Comparison of long- and short-rest periods during high-intensity interval exercise on transcriptomic responses in equine skeletal muscle.

The purpose of this study was to elucidate the skeletal muscle transcriptomic response unique to rest duration during high-intensity interval exercise. Thoroughbred horses performed three 1-min bouts of exercise at their maximal oxygen uptake (10.7-12.

A Case of Resectable Single-Nodule Intrahepatic Bile Duct Adenoma.

A 70-year-old man was incidentally diagnosed with a single hepatic mass lesion in his right hepatic lobe during a computed tomography scan. The lesion exhibited consistent enhancement with contrast agents on computed tomography (CT), magnetic resonance imaging (MRI), and hepatic arterial angiography. While a definitive diagnosis could not be made preoperatively, the lesion was surgically resected due to its slight enlargement over two months, suggesting a potential malignancy.

In situ X-ray diffraction studies on nominal composition of CLi under high pressure and temperature.

Superdense phase between graphite and Li metal, Li, has been significant in the research on both lithium-ion batteries (LIBs) and graphite intercalated compounds (GICs). However, a detailed method for synthesizing Li remains unknown owing to the limited information regarding Li and difficulties in distinguishing Li from Li. Thus, we performed in situ X-ray diffraction measurements on samples with the nominal composition of Li under high pressures and temperatures of up to 10 GPa and 400 , respectively.

Clinical validation of the suppressive impact of letrozole on liver fibrosis in patients with breast cancer undergoing continuous letrozole administration: A retrospective study.

Treatment strategies for preventing liver fibrosis have not yet been established. Letrozole, widely used for breast cancer, has recently been reported to suppress liver fibrosis in murine models. Therefore, we aimed to validate the suppressive effects of letrozole on liver fibrosis in the clinical setting.

Mutual associations among responsiveness to differential diagnostic tests for Cushing's disease, tumor size, and somatostatin receptor 5 expression in corticotroph tumors.

There are differences in the responsiveness to differential diagnostic tests for Cushing's disease (CD), corticotroph tumor size, and the somatostatin receptor (SSTR) 5 expression in corticotroph tumors between CD patients. The differences in SSTR5 expression are particularly significant for identifying therapeutic targets for CD. However, prospective predictors of SSTR5 expression remain unclear.

Increased accuracy and signal-to-noise ratio through recent improvements in infra-red video bolometer fabrication and calibration.

The infra-red video bolometer (IRVB) is a diagnostic equipped with an infra-red camera that measures the total radiated power in thousands of lines of sight within a large field of view. Recently validated in MAST-U [Fderici et al., Rev.

Atypical Imaging Findings in a Cortisol-producing Adrenal Adenoma Predominantly Composed of Lipid-poor Compact Cells.

Cortisol-producing adrenal adenomas consist of a mixture of lipid-rich clear and lipid-poor compact cells in varying proportions. Most adenomas are mainly composed of lipid-rich clear cells and typically exhibit low computed tomography (CT) attenuation values, high uptake on I-adosterol scintigraphy, and mild accumulation on F-fluorodeoxyglucose positron emission tomography/CT. However, adenomas predominantly composed of lipid-poor compact cells are rare, with limited evidence regarding their imaging characteristics.

Increased freedom of head movement mitigates stress and bacterial load in the airways of horses during transport.

Introduction: Protection of horse welfare during transport is crucial. The aim of this study was to determine the effect of head and neck restraint on behavior and airway bacteria.

Methods: In a randomized crossover study, six healthy Thoroughbreds were transported by road for 22 h in an individual bay with tight head restraint (50 cm short-rope) or loose head restraint (95 cm long-rope).

Mcl-1 expression is a predictive marker of response to gemcitabine plus nab-paclitaxel for metastatic pancreatic cancer.

Antiapoptotic protein, including Mcl-1, expression is frequently observed in pancreatic cancer. Gemcitabine plus nabpaclitaxel (GnP) is the standard chemotherapy for metastatic pancreatic cancer (MPC); however, predictive markers for its efficacy remain unestablished. This study evaluated the association between GnP's therapeutic effects and Mcl-1 expression in tissue samples obtained using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic tumor or percutaneous ultrasound-guided biopsy for metastatic liver tumor.

IGF-I concentration determines cell fate by converting signaling dynamics as a bifurcation parameter in L6 myoblasts.

Insulin-like growth factor (IGF)-I mediates long-term activities that determine cell fate, including cell proliferation and differentiation. This study aimed to characterize the mechanisms by which IGF-I determines cell fate from the aspect of IGF-I signaling dynamics. In L6 myoblasts, myogenic differentiation proceeded under low IGF-I levels, whereas proliferation was enhanced under high levels.

Developing a robust sensor for infrared imaging bolometers.

A new type of large area sensor for infrared imaging bolometers has been developed. It replaces the thin and fragile free-standing metal foils, which typically have been used, with a multi-layer coated sapphire (or diamond) substrate. Sapphire is transparent to mid-infrared wavelengths, is robust against transients, and can be thick enough to even be the vacuum window.

Optimal nocturnal care for pressure injury prevention in the care environment: A scoping review.

Aim: Nursing care activities conducted at night tend to disturb their sleep, but to our knowledge, no nocturnal care protocols for pressure injury prevention have been established. This scoping review aimed to map the nocturnal care for pressure injury prevention and propose nocturnal care recommendations that have a reduced impact on the patient's care environment.

Methods: Literature databases were searched and two independent researchers screened the articles according to the inclusion criteria and extracted the data.
