Exploring hydrogen adsorption and release in 2D MC-MXenes: structural and functional insights.

Two-dimensional MC-MXenes, characterized by their lightweight nature, tunable surface structures, and strong affinity for hydrogen, hold significant promise for addressing various challenges in hydrogen energy utilization. This study focuses on investigating the hydrogen adsorption and desorption properties, as well as the stability of hydrogenated compounds in 19 pure MC-MXenes nanosheets. The results indicate that hydrogen adsorption on MC primarily occurs through weak physisorption, with MnC and FeC from the fourth period, and AgC and CdC from the fifth period exhibiting the lowest adsorption energies.

Three different surgical methods for large-sized anterior mediastinal tumors in real-world practice.

Background: Video-assisted thoracoscopic surgery (VATS) for a relatively large mediastinal tumor (5.0-10.0 cm) remains controversial.

Measuring general sense of agency: a Japanese adaptation and validation of the sense of agency scale (J-SoAS).

The Sense of Agency (SoA) refers to the individual's perception of control over actions and their subsequent impact on the external environment. SoA encompasses multiple dimensions, such as implicit/local and explicit/general, which can be quantitatively assessed through cognitive tasks and psychometric questionnaires, respectively. The explicit and general aspect of SoA is commonly evaluated using the Sense of Agency Scale (SoAS).

The Antioxidant and Anti-Inflammatory Effects of the Main Carotenoids from Tomatoes via Nrf2 and NF-κB Signaling Pathways.

Oxidative stress and inflammation are crucial factors in the development of cardiovascular diseases. In previous research, the oxidative stress and inflammation models have frequently been explored independently. In the current study, we investigated the antioxidant and anti-inflammatory effects of tomato extract and its two main carotenoids (lutein and lycopene) with various concentrations using a rat cardiomyocyte model of co-existing oxidative stress and persistent chronic inflammation.

The Application Value of Esketamine and Dexmedetomidine in Preventing Postoperative Delirium and Hyperalgesia in Elderly Patients with Thoracic Anesthesia.

Objective: Our aim was to evauate the application value of esesketamine and dexmedetomidine in preventing postoperative hyperalgesia in elderly patients who received thoracic anesthesia.

Methods: A total of 94 elderly patients who underwent thoracic anesthesia in Sanmen People's Hospital from January 2021 to October 2022 were selected and divided into a dexmedetomidine group (n = 47) and an esketamine group (n = 47) by the random number table method. All patients were continuously received intravenous (IV) remifentanil.

Unexpected electro-catalytic activity of the CO reduction reaction on Cr-embedded poly-phthalocyanine realized by strain engineering: a computational study.

The electrochemical conversion of carbon monoxide (CO) into value-added products is highly promising for carbon utilization and CO removal. Based on previous theoretical studies, we computationally explored the effect of strain engineering on electrocatalysis of the CO reduction reaction (CORR) by two-dimensional (2D) transition metal embedded polyphthalocyanines (MPPcs). By calculating the adsorption energy of CO and the free energies of key intermediates on the MPPcs under uniaxial and biaxial strains, it was revealed that only CrPPc under biaxial strain has the potential to exhibit significant enhancement of the catalytic performance.

The Antioxidant and Anti-Inflammatory Effects of Flavonoids from Propolis via Nrf2 and NF-κB Pathways.

Accumulating evidence shows that oxidative stress and inflammation contribute to the development of cardiovascular disease. It has been suggested that propolis possesses antioxidant and anti-inflammatory activities. In this study, the antioxidant and anti-inflammatory effects of the main flavonoids of propolis (chrysin, pinocembrin, galangin, and pinobanksin) and propolis extract were researched.

Dosimetric Deviations of Bragg-Peak Position Shifts in Uniform Magnetic Fields for Magnetic Resonance Imaging-Guiding Proton Radiotherapy: A Monte Carlo Study.

To investigate dosimetric deviations in scanning protons for Bragg-peak position shifts, which were caused by proton spiral tracks in an ideal uniform field of magnetic resonance (MRI) imaging-guided proton radiotherapy (MRI-IGPRT). The FLUKA Monte-Carlo (MC) code was used to simulate the spiral tracks of protons penetrating water with initial energies of 70-270 MeV under the influence of field strength of 0.0-3.

Bilateral multiple intrapulmonary nodules: a puzzled and rare disease.

Primary intrapulmonary spindle cell thymomas (PISCT) are rare lesions that may be mistaken for a variety of benign and malignant epithelial or mesenchymal tumors. It is thought as one subtype of primary intrapulmonary thymomas (PIT). To the best of our knowledge, no bilateral multiple primary intrapulmonary spindle thymomas and treatment had been reported in literature.
