C NMR spectroscopy as well as the short bond between the platinum and the C4 atom of the pyridine ring in 1 (1.95 Å) indicate the formation of a novel carbene species. Compound 1 is remarkably stable (m.p. 246°C), probably due to the presence of intramolecular hydrogen bonds, and is formed instead of the expected cyclometalated product. R=n-hexyl.

Plant root carbon inputs drive methane production in tropical peatlands.
Sci Rep

School of Biosciences, University of Nottingham, Sutton Bonington, LE12 5RD, UK.
Tropical peatlands are carbon-dense ecosystems that are significant sources of atmospheric methane (CH). Recent work has demonstrated the importance of trees as an emission pathway for CH from the peat to the atmosphere. However, there remain questions over the processes of CH production in these systems and how they relate to substrate supply.

Our aim was to validate a sacral-mounted inertial measurement unit (IMU) for reconstructing running kinematics and comparing movement patterns within and between runners. IMU data were processed using Kalman and complementary filters separately. RMSE and Bland-Altman analysis assessed the validity of each filtering method against a motion capture system.

The objective of regulatory authorities is to ensure a favourable risk-benefit balance for medicines in their licenced indication, without seeking to establish their place in the therapeutic armamentarium beyond that. The licenced indication covers heterogeneous subpopulations and often does not sufficiently specify the characteristics of the patients who may benefit. The regulatory information does not always show the benefit over the standard treatment(s); moreover, it only reacts to the conditions specified in the developer's application, and lacks an assessment of the clinical relevance of the benefit and its uncertainties.

Objectives: The aim of this pilot study is to assess the feasibility of using the mobile photographic method (m-health) of teledentistry for oral screening and triaging of older patients living in aged care homes.
Methods: The study took place in 2023 in four aged care facilities in Egypt. Three trained dentists performed clinical oral examinations of the participants and filled in the World Health Organization (WHO) oral health assessment form.
Accuracy and Reproducibility of a Modified Echocardiographic Method for Right Ventricular Output Calculation in Neonates.
J Cardiovasc Dev Dis

Neonatal Intensive Care Unit, Azienda Ospedaliera Universitaria Integrata Verona, 37126 Verona, Italy.
We aimed to evaluate the accuracy and reproducibility of right ventricular output (RVO) using different anatomical landmarks: the internal pulmonary valve diameter (PVD) between the valve hinge points (hinge-PVD) according to the traditional technique, and PVD between the valve leaflet tips (tip-PVD). This was a retrospective analysis of prospective collected data. All neonates with echocardiographic measurements of RVO and left ventricular output (LVO) without congenital heart disease, including patent ductus arteriosus and patent foramen ovale > 3 mm, were included.
