Effective Utilization of Nanoporosity and Surface Area Guides Electrosynthesis over Soft-Landed Copper Oxide Catalyst Layers.

Porous nanomaterials find wide-ranging applications in modern medicine, optoelectronics, and catalysis, playing a key role in today's effort to build an electrified, sustainable future. Accurate in situ quantification of their structural and surface properties is required to model their performance and improve their design. In this article, we demonstrate how to assess the porosity, surface area and utilization of a model nanoporous soft-landed copper oxide catalyst layer/carbon interface, which is otherwise difficult to resolve using physisorption or capacitance-based methods.

Robotic-Assisted Pelvic Exenteration for Cervical Cancer: A Systematic Review and Novel Insights into Compartment-Based Imaging.

Patients with persistent or recurrent cervical cancer, following primary treatment with concurrent chemoradiation, represent a subgroup eligible for pelvic exenteration. In light of the substantial morbidity associated with open pelvic exenterations, minimally invasive surgical techniques have been introduced. This systematic review aims to analyze and discuss the current literature on robotic-assisted pelvic exenterations in cervical cancer.

Defect Engineering of MoTe via Thiol Treatment for Type III van der Waals Heterojunction Phototransistor.

Molybdenum ditelluride (MoTe) nanosheets have displayed intriguing physicochemical properties and opto-electric characteristics as a result of their tunable and small band gap ( ∼ 1 eV), facilitating concurrent electron and hole transport. Despite the numerous efforts devoted to the development of p-type MoTe field-effect transistors (FETs), the presence of tellurium (Te) point vacancies has caused serious reliability issues. Here, we overcome this major limitation by treating the MoTe surface with thiolated molecules to heal Te vacancies.

Direct visualization of ligands on gold nanoparticles in a liquid environment.

The interactions between gold nanoparticles, their surface ligands and the solvent critically influence the properties of these nanoparticles. Although spectroscopic and scattering techniques have been used to investigate their ensemble structure, a comprehensive understanding of these processes at the nanoscale remains challenging. Electron microscopy makes it possible to characterize the local structure and composition but is limited by insufficient contrast, electron beam sensitivity and the requirement for ultrahigh-vacuum conditions, which prevent the investigation of dynamic aspects.

Regorafenib in patients with pretreated advanced melanoma: a single-center case series.

Melanoma patients failing all approved treatment options have a poor prognosis. The antimelanoma activity of regorafenib (REGO), a multitargeted kinase inhibitor, has not been investigated in this patient population. The objective response rate and safety of REGO treatment in advanced melanoma patients was investigated retrospectively.

[Preventing decline of autonomy through the promotion of mental health: a randomized clinical trial for older adults with disabilities].

Among older adults with disabilities, maintaining active aging can often be compromised. However, the literature highlights a positive link between mental health and autonomy on one hand, and self-determined motivation on the other. Therefore, self-determined motivation may be improved by promoting mental health and, in the end, older adults autonomy.

Assessing groundwater denitrification spatially is the key to targeted agricultural nitrogen regulation.

Globally, food production for an ever-growing population is a well-known threat to the environment due to losses of excess reactive nitrogen (N) from agriculture. Since the 1980s, many countries of the Global North, such as Denmark, have successfully combatted N pollution in the aquatic environment by regulation and introduction of national agricultural one-size-fits-all mitigation measures. Despite this success, further reduction of the N load is required to meet the EU water directives demands, and implementation of additional targeted N regulation of agriculture has scientifically and politically been found to be a way forward.

Heterogeneous Pt-catalyzed transfer dehydrogenation of long-chain alkanes with ethylene.

The dehydrogenation of long-chain alkanes to olefins and alkylaromatics is a challenging endothermic reaction, typically requiring harsh conditions which can lead to low selectivity and coking. More favorable thermodynamics can be achieved by using a hydrogen acceptor, such as ethylene. In this work, the potential of heterogeneous platinum catalysts for the transfer dehydrogenation of long-chain alkanes is investigated, using ethylene as a convenient hydrogen acceptor.

"Learning a Way of Thinking"-World Café on Clinical Reasoning in Nursing and Midwifery Education and Practice across Five European Union Countries.

As a part of the Erasmus plus project, we designed a study with the aim of exploring the understanding of clinical reasoning as a concept, experiences of teaching clinical reasoning and practices related to using clinical reasoning in nursing and midwifery. A qualitative study was carried out using the World Café method, involving 44 participants from five European countries.

Primary leiomyosarcoma of the uterine cervix: an unusual case and critical appraisal.

Leiomyosarcomas of the uterine cervix are rare, mostly occurring in perimenopausal women. Diagnosis is based on pathology and immunohistochemistry. Surgery with a total abdominal hysterectomy and bilateral salpingo-oophorectomy remains the standard.

Charging of Vitreous Samples in Cryogenic Electron Microscopy Mitigated by Graphene.

Cryogenic electron microscopy can provide high-resolution reconstructions of macromolecules embedded in a thin layer of ice from which atomic models can be built . However, the interaction between the ionizing electron beam and the sample results in beam-induced motion and image distortion, which limit the attainable resolutions. Sample charging is one contributing factor of beam-induced motions and image distortions, which is normally alleviated by including part of the supporting conducting film within the beam-exposed region.

Size of cerium dioxide support nanocrystals dictates reactivity of highly dispersed palladium catalysts.

The catalytic performance of heterogeneous catalysts can be tuned by modulation of the size and structure of supported transition metals, which are typically regarded as the active sites. In single-atom metal catalysts, the support itself can strongly affect the catalytic properties. Here, we demonstrate that the size of cerium dioxide (CeO) support governs the reactivity of atomically dispersed palladium (Pd) in carbon monoxide (CO) oxidation.

Case report: a robotic-vaginal approach for total vaginectomy and hysterectomy with pelvic sentinel lymph node dissection in primary vaginal melanoma: a 10-step technique and literature review.

Introduction: Primary vaginal melanoma is extremely rare, has a poor prognosis, and occurs mostly in elderly women. The diagnosis is based on histology and immunohistochemistry of a biopsy. Given the rarity of vaginal melanoma, no standardized treatment guidelines are established; however, surgery is the primary treatment modality in the absence of metastatic disease.

Robotic surgery in early and advanced ovarian cancer: Case selection for surgical staging and interval debulking surgery.

Objective: During the last decade several case series have been published on robotic surgery in early and advanced stage ovarian cancer. Although most studies lack a significant oncological follow-up, more importantly criteria for patient selection for both robotic surgical staging (R-SS) and robotic interval debulking surgery (R-IDS) are not well defined. The objective of this study was to assess the surgical and oncological outcomes, using well-defined selection criteria, between robotic and open surgery in early and advanced stage ovarian cancer.

Evidence for a modulating effect of transcutaneous auricular vagus nerve stimulation (taVNS) on salivary alpha-amylase as indirect noradrenergic marker: A pooled mega-analysis.

Background: Non-invasive transcutaneous auricular vagus nerve stimulation (taVNS) has received tremendous attention as a potential neuromodulator of cognitive and affective functions, which likely exerts its effects via activation of the locus coeruleus-noradrenaline (LC-NA) system. Reliable effects of taVNS on markers of LC-NA system activity, however, have not been demonstrated yet.

Methods: The aim of the present study was to overcome previous limitations by pooling raw data from a large sample of ten taVNS studies (371 healthy participants) that collected salivary alpha-amylase (sAA) as a potential marker of central NA release.

The moderating role of socioeconomic status on the relationship between teacher social support and sense of belonging to school.

Background: Teacher social support (TSS) has been identified as one of the most important factors of success and well-being for students. Yet, there is a gap in the literature regarding the impact of students' socioeconomic status (SES) on their perceptions of TSS, and whether SES may impact the strength of the relationship between teacher social support and students' sense of belonging to school (SBS).

Aims: In this preregistered study, we aimed at filling this gap by testing the moderating role of SES on the TSS-SBS link, along with the direct associations between these variables.

Socioeconomic status and social anxiety: attentional control as a key missing variable?

Background And Objectives: The aim was to examine the role of attentional control as a psychological factor involved in socioeconomic status-related mental health differences, and specifically in social anxiety. Based on the literature on socioeconomic status differences in cognitive abilities and attentional control theory, we hypothesized that attentional control would account for the relation between socioeconomic status and social anxiety. We tested this hypothesis in an integrative model also including trait anxiety and subjective socioeconomic status.

Robotic Staging of Cervical Cancer With Simultaneous Detection of Primary Pelvic and Secondary Para-Aortic Sentinel Lymph Nodes: Reproducibility in a First Case Series.

Objective: Discrepancies exist among international guidelines on the surgical staging of para-aortic lymph nodes in locally advanced cervical cancer (LACC), varying from considering a para-aortic lymph node dissection, at least up to the inferior mesenteric artery, to a complete para-aortic lymph node dissection. In this study, we aim to assess the reproducibility of our recently reported robotic technique using indocyanine green for identifying besides primary pelvic sentinel lymph nodes (SLNs), secondary para-aortic SLNs in a first case-cohort of cervical cancer patients.

Methods: A retrospective case series of LACC patients with/without suspicious pelvic lymph nodes (LNs) on imaging (including two patients with an additional suspicious para-aortic LN) is reported.

Metal-Polymer Heterojunction in Colloidal-Phase Plasmonic Catalysis.

Plasmonic catalysis in the colloidal phase requires robust surface ligands that prevent particles from aggregation in adverse chemical environments and allow carrier flow from reagents to nanoparticles. This work describes the use of a water-soluble conjugated polymer comprising a thiophene moiety as a surface ligand for gold nanoparticles to create a hybrid system that, under the action of visible light, drives the conversion of the biorelevant NAD to its highly energetic reduced form NADH. A combination of advanced microscopy techniques and numerical simulations revealed that the robust metal-polymer heterojunction, rich in sulfonate functional groups, directs the interaction of electron-donor molecules with the plasmonic photocatalyst.

Learn to breathe, breathe to learn? No evidence for effects of slow deep breathing at a 0.1 Hz frequency on reversal learning.

This study sought to investigate whether slow deep breathing (SDB) facilitates reversal learning. We also explored whether SDB modulates the renewal effect. After learning a series of cue-outcome associations (early acquisition phase) in a predictive learning task, 37 participants paced their breathing according to a normal (NPB group; 0.

Prospective non-interventional BELOVA/BGOG-ov16 study on safety of frontline bevacizumab in elderly patients with FIGO stage IV ovarian cancer: a study of the Belgian and Luxembourg Gynaecological Oncology Group.
