Random walks with invariant loop probabilities comprise a wide family of Markov processes with site-dependent, one-step transition probabilities. The whole family, which includes the simple random walk, emerges from geometric considerations related to the stereographic projection of an underlying geometry into a line. After a general introduction, we focus our attention on the elliptic case: random walks on a circle with built-in reflexing boundaries.

Background: Nocturnal blood pressure dipping is crucial for cardiovascular health, but the effect of exercise on this phenomenon is not well understood. This study aims to investigate how a single session of aerobic exercise impacts nocturnal blood pressure dipping in individuals with hypertension who are on medication.
Methods: Twenty hypertensive adults (67 ± 16 years) participated in a randomised, parallel-group clinical trial.

Background: Cardiac rehabilitation programs are planned to reduce the physiological and psychological stress of Cardiovascular Disease, decrease the risk of mortality secondary to CVD, improve cardiovascular function, and help patients to achieve their highest quality of life. However, data on the safety and efficacy of exercise training (ET) in patients with implantable cardioverter defibrillators (ICDs) is sparse. Exercise interventions in those with an ICD have not been extensively studied.

Background: The symptoms, comorbidities and treatment burden associated with chronic kidney disease (CKD) can be debilitating and limit life participation in patients with CKD not requiring kidney replacement therapy (KRT). The aim of this study was to identify the characteristics, content and psychometric properties of patient-reported outcome measures (PROMs) used to assess life participation in patients with CKD.
Methods: We searched MEDLINE, Embase, PsycINFO and CINAHL from database inception to February 2023 for all studies that reported life participation in patients with CKD (stages 1-5 not requiring kidney replacement therapy).

Random walks and related spatial stochastic models have been used in a range of application areas, including animal and plant ecology, infectious disease epidemiology, developmental biology, wound healing and oncology. Classical random walk models assume that all individuals in a population behave independently, ignoring local physical and biological interactions. This assumption simplifies the mathematical description of the population considerably, enabling continuum-limit descriptions to be derived and used in model analysis and fitting.

Scaffolds play a crucial role in tendon healing by providing structural support, promoting cell infiltration, and guiding tissue regeneration. Polycaprolactone (PCL) has been used as a polymer in biological scaffolds for several tissue engineering studies. This study aimed to investigate the effects of curcumin-loaded PCL scaffold on Achilles tendon using a tenotomy model in rats.
