Synergistic effect of ligand-cluster structure and support in gold nanocluster catalysts for selective hydrogenation of alkynes.

In the field of nanocluster catalysis, it is crucial to understand the interplay of different parameters, such as ligands, support and pretreatment and their effect on the catalytic process. In this study, we chose the selective hydrogenation of phenylacetylene as a model reaction and employed two gold nanoclusters as catalysts, the phosphine protected Au and the thiolate protected Au, each with different binding motifs. They were supported on MgO, AlO and a hydrotalcite (HT), chosen for their different acidity.

Subjective motoric cognitive risk syndrome: Preliminary prevalence from an online survey of a German cohort aged 50.

The motoric cognitive risk syndrome (MCR) is a novel and clinically relevant pre-dementia syndrome indicating a higher dementia risk (e.g., for Alzheimer's disease).

The importance of organisational culture for health system resilience: A qualitative analysis of factors that supported health care workers in Germany during the COVID-19 pandemic.

Health system resilience is defined as the ability of a system to prepare, manage, and learn from shocks. This study investigates the resilience of the German health system by analysing the system-related factors that supported health care workers, a key building block of the system, during the COVID-19 pandemic. We thematically analysed data from 18 semi-structured interviews with key informants from management, policy and academia, 17 in-depth interviews with health care workers, and 10 focus group discussions with health care workers.

Beta-Blockers and Cutaneous Melanoma Outcomes: A Systematic Review and Random-Effects Meta-Analysis.

Beta-blockers have generated an exciting discourse for their potential as a cheap, safe, and effective adjunctive therapy for cutaneous melanoma patients, but the field remains murky. This systematic review investigates the association between beta-blocker use and survival outcomes in cutaneous melanoma patients. We reviewed 12 studies with 21,582 patients in a network meta-analysis and found a benefit between beta-blocker use and disease-free survival but no other significant association for melanoma-specific or overall survival.

Lobectomy vs. MRgLITT in Temporal Lobe Epilepsy (TLE): A Pilot Study Investigating Vestibulo-Spatial Functions.

: About 65 million people worldwide are affected by epilepsy, with temporal lobe epilepsy being the most common type resistant to drugs and often requiring surgical treatment. Although open surgical approaches, such as temporal lobectomy, have been the method of choice for decades, minimally invasive MRgLITT has demonstrated promising results. However, it remains unknown whether patients who underwent one of these two approaches would show better performance on vestibulo-spatial tasks.
