School of Physics, Mathematics and Computing, The University of Western Australia, Perth, Australia.
Background/aim: Tumors exhibit impaired blood flow and hypoxic areas, which can reduce the effectiveness of treatments. Characterizing these tumor features can inform treatment decisions, including the use of vasculature modulation therapies. Imaging provides insight into these characteristics, with techniques varying between clinical and preclinical settings.

Department of Orthopedics, Hainan Hospital of PLA General Hospital, Hainan, China.
Background: Prolonged dependence on mechanical ventilation is a common occurrence in clinical ICU patients and presents significant challenges for patient care and resource allocation. Predicting prolonged dependence on mechanical ventilation is crucial for improving patient outcomes, preventing ventilator-associated complications, and guiding targeted clinical interventions. However, specific tools for predicting prolonged mechanical ventilation among ICU patients, particularly those with critical orthopaedic trauma, are currently lacking.

Materials And Methods: Examined 147 patients with confirmed NTML, for which they received treatment in accordance with the results of drug susceptibility of the pathogen. Before and during treatment, a study of clinical, biochemical blood tests, urinalysis, electrocardiogram, external respiration function, ultrasound of the abdominal organs and kidneys was performed.

Republican Scientific and Practical Center of Neurology and Neurosurgery, Minsk, Belarus.
Objective: To analyze the results of nocturnal breathing parameters during sleep based on nocturnal pulse oximetry and to study of characteristics of external respiration in genetically confirmed patients with dystrophic myotonia (DM).
Material And Methods: The subjects of the study were patients with genetically confirmed DM types 1 and 2 who were hospitalized in the neurological departments of the Republican Scientific and Practical Center for Neurology and Neurosurgery. The clinical picture of the disease, comorbidities, sleep questionnaires, laboratory tests, overnight pulse oximetry and spirometry were performed and analyzed.
Physiological relevance, localization and substrate specificity of the alternative (type II) mitochondrial NADH dehydrogenases of .

Department of Biotechnology, Delft University of Technology, Delft, Netherlands.
Mitochondria from harbor a branched electron-transport chain containing a proton-pumping Complex I NADH dehydrogenase and three Type II NADH dehydrogenases (NDH-2). To investigate the physiological role, localization and substrate specificity of these enzymes, the growth of various NADH dehydrogenase knockout mutants was quantitatively characterized in shake-flask and chemostat cultures, followed by oxygen-uptake experiments with isolated mitochondria. NAD(P)H:quinone oxidoreduction of the three NDH-2 were individually assessed.
