Objective: This study investigated the effects of sleep deprivation (SD) on balance after normal sleep, 24 h of SD, and subsequent rest under eyes-open (EO) and eyes-closed (EC) conditions. Our aim was to ascertain whether the reduced efficiency of balance control following SD is generalized or selective.

Method: Nineteen participants (12 females, 7 males) completed the Pittsburgh Sleep Quality Index (PSQI).

Background: Sarcopenia is a progressive age-related skeletal muscle disease associated with adverse outcomes in those with cardiovascular disease. In this study, the prevalence of sarcopenia and its effect on clinical outcomes in heart failure with mildly reduced ejection fraction (HFmrEF) patients were examined.

Methods: A total of 722 patients from three centres who applied to the outpatient clinic with the diagnosis of HFmrEF between 01 January 2020 and 01 June 2021 were included in the study retrospectively.

Article Synopsis
  • Testing the biocompatibility of dental materials is crucial and this study focused on four specific materials: Mineral Trioxide Aggregate, Biodentine, Harvard BioCal-CAP, and Oxford ActiveCal PC.
  • The evaluation used zebrafish embryos and larvae to assess survivability, hatching rates, and apoptosis through various toxicity tests.
  • Results indicated that higher concentrations of these materials negatively affected survival and hatching, with Biodentine and Oxford ActiveCal PC showing better biocompatibility than Mineral Trioxide Aggregate.

Background: This study is a randomized controlled, biopsychosocial study investigating the effectiveness of pain neuroscience education (PNE) and motor imagery-based exercise protocol (MIEP) on fibromyalgia pain.

Methods: Our study has four groups (MIEP n = 12, PNE n = 12, MIEP + PNE n = 14, Control n = 12) and all participants (n = 50) consist of patients diagnosed with fibromyalgia with chronic back pain. The primary outcome measure was pain intensity, and secondary outcome measures were beliefs, kinesiophobia, anxiety-depression, cognitive-mood, self-esteem, and body awareness.

Introduction: Parkinson disease is the world's second most prevalent neurological disease. In this disease, intracytoplasmic neuronal inclusions are observed in enteric neurons in the gastrointestinal tract, and the composition of the intestinal microbiome is altered. These changes correlate with the motor phenotype.
