Aims: Reverse Cholesterol Transport (RCTr) is the mechanism by which excess cholesterol from peripheral tissues is transported to the liver for hepatobiliary excretion, thereby inhibiting foam cell formation and the development of atherosclerosis. Exercise affects RCTr, by influencing high-density lipoprotein cholesterol (HDL) through remodeling and by promoting hepatobiliary sterol excretion. The objectives of this systematized review of animal studies is to summarize the literature and provide an overview of the effects of chronic exercise (at least two weeks) on apolipoproteins (Apo A-I, Apo-E), Paraoxonase-1 (PON1), ATP-binding cassette transporters (ABCA1, ABCG1, ABCG4, ABCG5, ABCG8), scavenger receptor class B type I (SR-BI), cholesteryl ester transfer protein (CETP), low-density lipoprotein receptor (LDLr) and cholesterol 7 alpha-hydroxylase (CYP7A1) and Niemann-Pick C1-like 1 (NPC1L1).
Materials And Methods: Three electronic databases (PubMed, Science Direct and Google Scholar) were searched for eligible studies conducted from the earliest available date to August 2018.
Key Findings: Most of studies investigate the effects of low to moderate intensity aerobic training on RCTr elements. The majority were on exercised rats undertaking moderate intensity aerobic training.
Significance: This review highlights that moderate intensity and longer-term training has a greater effect on RCTr elements than low intensity training. There a few studies examining high intensity training which warrants further investigation.

The effectiveness of psychologically-informed physiotherapy for people with neck pain and the mediating role of illness perceptions: a replicated single-case experimental design study.
Disabil Rehabil
January 2025
Amsterdam Movement Sciences, Faculty of Behavioural and Movement Sciences, Vrije Universiteit Amsterdam, Amsterdam, The Netherlands.
Purpose: (1) To evaluate the effectiveness of personalised psychologically-informed physiotherapy in people with neck pain; (2) To explore the mediating role of changes in illness perceptions.
Method: In this replicated single-case study, 14 patients with non-specific neck pain at risk for chronicity received a personalised intervention addressing unhelpful illness perceptions and dysfunctional movement behaviour, according to principles of cognitive functional therapy. Outcomes included the mediating role of illness perceptions on overall effect, function, pain intensity and self-efficacy.
Move Better, Live Better: A novel supervised combined training for peripheral arterial disease: A quasi-experimental approach.

Objective: This study aimed to analyze the effect of a novel supervised exercise therapy (SET) program based on intermittent treadmill walking and circuit-based moderate-intensity functional training (MIFT) on walking performance and HRQoL in PAD patients.
Design: All participants underwent a 12-week SET that involved 15 to 30 minutes of treadmill walking followed by a 15-minute moderate-intensity functional training (MIFT) continued by 12-week of follow-up. Maximum walking distance (MWD), pain-free walking distance (PFWD), gait speed and estimated peak oxygen uptake (peak VO2) were calculated through the 6-minute walk test (6-MWT) and HRQoL through the Short Form-36 (SF-36) and the Vascular Quality of Life Questionnaire-6 (VascuQol-6).
Immunohistochemical investigation of transient receptor potential melastatin-2 and spexin immunoreactivity in atopic dermatitis and mycosis fungoides.
Arch Dermatol Res
January 2025
Department of Dermatology, Firat University Hospital, Elazig, TR23119, Turkey.
Background: Atopic dermatitis (AD) is a chronic, pruritic, and inflammatory dermatosis seen in individuals with an atopic predisposition. This study aimed to examine the immunoreactivity of spexin and TRPM2 in skin samples from patients with AD and MF lesions using immunohistochemical methods.
Materials And Methods: The study utilized a total of 60 skin samples, comprising 20 from AD patients, 20 from MF patients, and 20 from control subjects.
Effect of Strength Training on Body Composition, Volumetrics and Strength in Female Breast Cancer Survivors.
Healthcare (Basel)
December 2024
Department of Health Sciences, University of Burgos, 09001 Burgos, Spain.
Background/aims: This cross-sectional study investigates body composition and strength in female breast cancer survivors, focusing on the effects of radical mastectomy and the presence of upper extremity lymphoedema. The main objective was to understand body composition, volumetry, and strength, as well as response to strength training in female breast cancer survivors.
Methods: Twenty-three women (aged 42-74 years old) with radical mastectomy in the last five years were assessed by measuring body composition (weight, water percentage, fat, muscle, and lean mass), maximal strength, perimeters, and brachial volumes.
Verbal Memory is Higher After Aerobic Exercise When Compared to Muscle Stretching.

Department of Psychology, Central Michigan University, Mt. Pleasant, MI, USA (GTR, JAP, HO).
Acute exercise is linked to memory improvement. Several mediators may influence the effect of exercise such as the type of exercise (aerobic exercise, muscle stretching). The primary aim was to analyze memory outcomes after a 20-min bout of aerobic exercise or muscle stretching.
