High-intensity interval training to improve cardiorespiratory fitness in a patient with frailty and multimorbidity: A case report.

Background: Low cardiorespiratory fitness predicts worse postoperative outcomes, exacerbated by age and frailty. Preoperative High-Intensity Interval Training (HIIT) improves cardiorespiratory fitness and postoperative outcomes but is challenging to implement in frailty due to perceived risks.

Purpose: The aim of this case report was to demonstrate feasibility of HIIT in a patient with frailty and multimorbidity.

Prediction of tumor response to neoadjuvant chemotherapy in high-grade osteosarcoma using clustering-based analysis of magnetic resonance imaging: an exploratory study.

Purpose: To evaluate the ability of magnetic resonance imaging (MRI)-based clustering analysis to predict the pathological response to neoadjuvant chemotherapy (NACT) in patients with primary high-grade osteosarcoma.

Materials And Methods: Twenty-two patients were included in this retrospective study. All patients underwent MRIs before and after NACT.

Coding Dynamics of the Striatal Networks During Learning.

The rat dorsomedial (DMS) and dorsolateral striatum (DLS), equivalent to caudate nucleus and putamen in primates, are required for goal-directed and habit behaviour, respectively. However, it is still unclear whether and how this functional dichotomy emerges in the course of learning. In this study, we investigated this issue by recording DMS and DLS single neuron activity in rats performing a continuous spatial alternation task, from the acquisition to optimized performance.

Social neuroscience: Primate research goes wireless.

A new study leads the way to a more ethical and ethologically meaningful way of investigating brain functions of complex behaviors in social animals.

The carbon monoxide prodrug oCOm-21 increases Ca sensitivity of the cardiac myofilament.

Patients undergoing cardiopulmonary bypass procedures require inotropic support to improve hemodynamic function and cardiac output. Current inotropes such as dobutamine, can promote arrhythmias, prompting a demand for improved inotropes with little effect on intracellular Ca flux. Low-dose carbon monoxide (CO) induces inotropic effects in perfused hearts.
