MXenes as Heterogeneous Thermal Catalysts: Regioselective Anti-Markovnikov Hydroamination of Terminal Alkynes with 10 h Turnover Frequencies.

Due to their conductive properties and optoelectronic tunability, MXenes have revolutionized the area of electrocatalysis and active materials in supercapacitors. In comparison, there are only a few reports on MXenes as thermal catalysts for general organic reactions. Herein, the unprecedented catalytic activity of TiC MXene for the hydroamination of alkynes is reported, overcoming the limitations of poor activity, lack of selectivity, and stability, which are generally encountered in the solid catalysts known so far.

Understanding the Difficulties in Diagnosing Neonatal Sepsis: Assessing the Role of Sepsis Biomarkers.

Background: Neonatal sepsis is a serious condition with high rates of morbidity and mortality, caused by the rapid growth of microorganisms that trigger a systemic reaction. Symptoms can range from mild to severe presentations. The causative microorganism is usually transmitted from mothers, especially from the urogenital tract, or can originate from the community or hospital.

The Critical Role of Pulse Oximetry Screening for Congenital Heart Disease and Patent Ductus Arteriosus in Newborns.

Introduction: Congenital heart disease (CHD) is diagnosed with high prevalence. Pulse oximetry and clinical examination are screening tools to aid in obtaining a CHD diagnosis.

Materials And Methods:  We conducted a retrospective longitudinal study over three years, screening 1188 newborns admitted to the neonatal intensive care unit (NICU) during the first 72 hours of life.

Comparative Biomechanical Analysis of Kirschner Wire Fixation in Dorsally Displaced Distal Radius Fractures.

Objective: This study aims to evaluate and compare the biomechanical performance of two Kirschner (K) wire configurations-the intra-focal and interfragmentary techniques-for the fixation of dorsally displaced distal radius fractures. The study also assesses the impact of K-wire diameter (1.6 mm vs.

The Diagnosis and Evolution of Patients with LARS Syndrome: A Five-Year Retrospective Study from a Single Surgery Unit.

Objectives: The aim of the study was to assess the diagnosis and evolution of low anterior rectal resection syndrome (LARS) in patients admitted to a tertiary surgical center in Romania.

Materials And Methods: From 120 patients initially included in the analysis, after applying the exclusion criteria, we selected 102 patients diagnosed and operated on for neoplasm of the upper, middle, and lower rectum for which resection and excision (partial or total) of mesorectum was associated. All the patients we treated in the general surgery department of the County Emergency Hospital of Craiova within a time frame of 5 years (1 October 2017-1 September 2022), and all experienced at least one symptom associated with LARS.
