Exercise-induced inflammation alters the perception and visual exploration of emotional interactions.

Introduction: The study aimed to investigate whether an exercise-induced pro-inflammatory response alters the perception as well as visual exploration of emotional body language in social interactions.

Methods: In a within-subject design, 19 male, healthy adults aged between 19 and 33 years performed a downhill run for 45 min at 70% of their VO on a treadmill to induce maximal myokine blood elevations, leading to a pro-inflammatory status. Two control conditions were selected: a control run with no decline and a rest condition without physical exercise.

Respiratory and Metabolic Responses of CD4 + T Cells to Acute Exercise and Their Association with Cardiorespiratory Fitness.

Introduction: The study aimed to investigate to what extent acute endurance exercise, especially eccentric exercise and cardiorespiratory fitness, affects the metabolic profile of CD4 + cells.

Methods: Fifteen male, healthy adults aged between 20 and 33 yr with a maximal oxygen uptake (V̇O 2max ) between 44 and 63 mL·kg -1 ·min -1 performed a downhill run (DR) and a level run (LR) for 45 min at 70% of their V̇O 2max on a treadmill in a crossover design. Blood samples were taken before (T0), directly after (T1), 3 h after (T3), and 24 h (T24) after each exercise for analyzing leukocyte numbers and cytokine levels.

T-cell-derived TNF-α and a cluster of immunological parameters from plasma allow a separation between SARS-CoV-2 convalescent versus vaccinated elite athletes.

Guidelines for medical clearing after SARS-CoV-2 infection in elite athletes do not include T-cell immunity aspects despite its relevance in the course of COVID-19 disease. Therefore, we aimed to analyze T-cell-related cytokines before and after activation of CD4 T-cells. We sampled professional indoor sports athletes at medical clearing after SARS-CoV-2 infection obtaining clinical, fitness data, and serological data including CD4 T-cell cytokines.

Resistance to BRAF Inhibitors: EZH2 and Its Downstream Targets as Potential Therapeutic Options in Melanoma.

Activating BRAF mutations occurs in 50-60% of malignant melanomas. Although initially treatable, the development of resistance to BRAF-targeted therapies (BRAFi) is a major challenge and limits their efficacy. We have previously shown that the BRAF signaling pathway mediates the expression of EZH2, an epigenetic regulator related to melanoma progression and worse overall survival.

Laser-Induced Action Potential-Like Measurements of Cardiomyocytes on Microelectrode Arrays for Increased Predictivity of Safety Pharmacology.

Life-threatening drug-induced cardiac arrhythmia is often preceded by prolonged cardiac action potentials (AP), commonly accompanied by small proarrhythmic membrane potential fluctuations. The shape and time course of the repolarizing fraction of the AP can be pivotal for the presence or absence of arrhythmia. Microelectrode arrays (MEA) allow easy access to cardiotoxic compound effects via extracellular field potentials (FP).

Systemic Activation of Neutrophils by Immune Complexes Is Critical to IgA Vasculitis.

In IgA vasculitis (IgAV) perivascular deposition of IgA1 immune complexes (IgA-ICs) is traditionally considered the fundamental trigger for polymorphonuclear neutrophil (PMN)-mediated damage. We propose that IgA-IC deposition, although mandatory, is not sufficient alone for IgAV. Serum IgA-IC levels and IgA-IC binding to PMNs were quantified in IgAV patients and controls.

Expression and activity of IL-17 receptor subunits in human cutaneous cells as targets for anti-IL-17 therapeutic antibodies.

The key players in different chronic inflammatory skin diseases are cytokines belonging to the IL-17 group, IL-17 receptors and a T helper cell population, Th17 cells. Successful therapeutic strategies that target either IL-17 or the major IL-17 receptor IL-17RA have confirmed the immune-pathogenic pathway. To study the IL-17-ligand - receptor axis at the molecular level, a number of cutaneous cell types from healthy human subjects has been cultured and analyzed for the expression of IL-17 receptors.

Recovery-Stress Response of Blood-Based Biomarkers.

The purpose of this study was to investigate blood-based biomarkers and their regulation with regard to different recovery-stress states. A total of 35 male elite athletes (13 badminton, 22 soccer players) were recruited, and two venous blood samples were taken: one in a 'recovered' state (REC) after a minimum of one-day rest from exercise and another one in a 'non-recovered' state (NOR) after a habitual loading microcycle. Overall, 23 blood-based biomarkers of different physiologic domains, which address inflammation, muscle damage, and tissue repair, were analyzed by Luminex assays.

BRAF/EZH2 Signaling Represses miR-129-5p Inhibition of SOX4 Thereby Modulating BRAFi Resistance in Melanoma.

Many melanomas are associated with activating BRAF mutation. Targeted therapies by inhibitors of BRAF and MEK (BRAFi, MEKi) show marked antitumor response, but become limited by drug resistance. The mechanisms for this are not fully revealed, but include miRNA.

Abdominal Obesity-Related Disturbance of Insulin Sensitivity Is Associated with CD8 EMRA Cells in the Elderly.

Aging and overweight increase the risk of developing type 2 diabetes mellitus. In this cross-sectional study, we aimed to investigate the potential mediating role of T-EMRA cells and inflammatory markers in the development of a decreased insulin sensitivity. A total of 134 healthy older volunteers were recruited (age 59.

Sympathetic Nervous System and Exercise Affects Cognition in Youth (SNEACY): study protocol for a randomized crossover trial.

Background: There is an increasing prevalence of physical inactivity during childhood, which is associated with a variety of health problems. However, the mechanisms by which acute exercise benefits cognition in childhood remains unknown. Here we describe the protocol for a randomized crossover trial called SNEACY (Sympathetic Nervous System & Exercise Affects Cognition in Youth), a study designed to better understand mechanisms linking acute exercise and cognition in 9-10-year-old healthy, cognitively normal children.

Physical Activity and Mental Health of Patients with Pulmonary Hypertension during the COVID-19 Pandemic.

The aim of the study was to analyze the effect of personal restrictions on physical activity, mental health, stress experience, resilience, and sleep quality in patients with pulmonary hypertension (PH) during the "lockdown" period of the COVID-19 pandemic. In total, 112 PH patients and 52 age-matched healthy control subjects completed a questionnaire on the topics of physical activity, mental health, resilience, and sleep quality. PH patients had significantly lower physical activity, mental health, and sleep quality compared to age-matched healthy controls.

Early Contact after Hospital Discharge Does Not Prevent Readmission in Patients Undergoing Pancreaticoduodenectomy.

Studies suggest that early contact (EC) after hospital discharge may help reduce hospital readmissions among medical patients. The objective of this study is to determine if EC after hospital discharge in patients undergoing a pancreaticoduodenectomy (PD) can reduce readmission. We performed a retrospective study of 35 patients who underwent PD over 18 months.

Method performance and clinical workflow outcomes associated with meconium and umbilical cord toxicology testing.

Objective: Neonatal abstinence syndrome (NAS) is a rising concern with unknown long-term effects. It is apparent that higher cost of care, impact on the community and reduced quality of life are associated with similar etiologies (e.g.

Human and Environmental Toxicity of Sodium Lauryl Sulfate (SLS): Evidence for Safe Use in Household Cleaning Products.

Environmental chemical exposure is a major concern for consumers of packaged goods. The complexity of chemical nomenclature and wide availability of scientific research provide detailed information but lends itself to misinterpretation by the lay person. For the surfactant sodium lauryl sulfate (SLS), this has resulted in a misunderstanding of the environmental health impact of the chemical and statements in the media that are not scientifically supported.

Effects of ketamine, s-ketamine, and MK 801 on proliferation, apoptosis, and necrosis in pancreatic cancer cells.

Background: Adenocarcinoma of the pancreas is one of the most aggressive cancer diseases affecting the human body. The oncogenic potential of this type of cancer is mainly characterized by its extreme growth rate triggered by the activation of signaling cascades. Modern oncological treatment strategies aim at efficiently modulating specific signaling and transcriptional pathways.

Effects of ropivacaine, bupivacaine and sufentanil in colon and pancreatic cancer cells in vitro.

The perioperative period is supposed to be a vulnerable period for cancer progression. Results of clinical studies indicate that the use of regional anesthesia can influence and improve oncological outcome of cancer patients. Uncontrolled cell proliferation and resistance to apoptotic cell death are important characteristics of solid tumors.

A combined therapeutic regimen of buspirone and environmental enrichment is more efficacious than either alone in enhancing spatial learning in brain-injured pediatric rats.

Buspirone, a 5-HT1A receptor agonist, and environmental enrichment (EE) enhance cognition and reduce histopathology after traumatic brain injury (TBI) in adult rats, but have not been fully evaluated after pediatric TBI, which is the leading cause of death in children. Hence, the aims of this study were to assess the efficacy of buspirone alone (Experiment 1) and in combination with EE (Experiment 2) in TBI postnatal day-17 male rats. The hypothesis was that both therapies would confer cognitive and histological benefits when provided singly, but their combination would be more efficacious.

[The Bremen periodic health exam - feasibility of a new concept].

Background: All members of the Statutory Health Insurance are entitled to receive preventive health examinations. The current concept, however, does not take individual risk factors into account systematically. To improve this, the "Bremen Health Examination" was developed.
