Myocardial infarction (MI) is a serious cardiovascular disease as the leading cause of death globally. Hence, reconstruction of the cardiac tissue comes at the forefront of strategies adopted to restore heart functions following MI. In this investigation, we studied the capacity of rat adipose-derived mesenchymal stem cells (r-AdMSCs) and decellularized porcine pericardium (DPP) to restore heart functions in MI animals. MI was induced in four different groups, three of which were treated either using DPP (MI-DPP group), stem cells (MI-SC group), or both (MI-SC/DPP group). Cardiac functions of these groups and the Sham group were evaluated using echocardiography, the intraventricular pressure gradient (IVPG) on weeks 2 and 4, and intraventricular hemodynamics on week 4. On day 31, the animals were euthanized for histological analysis. Echocardiographic, IVPG and hemodynamic findings indicated that the three treatment strategies shared effectively in the regeneration process. However, the MI-SC/DPP group had a unique synergistic ability to restore heart functions superior to the other treatment protocols. Histology showed that the MI-SC/DPP group presented the lowest ( < 0.05) degeneration score and fibrosis % compared to the other groups. Conclusively, stem cell-seeded DPP is a promising platform for the delivery of stem cells and restoration of heart functions post-MI.

Background: Pulmonary hypertension (PH) is a systemic illness with increasingly subtle disease manifestations including sleep disruption. Patients with PH are at increased risk for disturbances in circadian biology, although to date there is no data on "morningness" or "eveningness" in pulmonary vascular disease.
Research Questions: Our group studied circadian rhythms in PH patients based upon chronotype analysis, to explore whether there is a link between circadian parameters and physiologic risk-stratifying factors to inform novel treatment strategies in patients with PH?
Study Design And Methods: We serially recruited participants from July 2022 to March 2024, administering in clinic the Munich Chronotype Questionnaire (MCTQ).

Chronic cough can coexist with or without pulmonary and extrapulmonary conditions and can be refractory to therapies that improve these associated conditions. It is underlined by cough hypersensitivity, which is characterized by increased cough responses to stimuli that affect the airways and vagally innervated tissues as well as by excessive cough responses to innocuous stimuli, and it is caused by neuroinflammatory and neuropathic mechanisms at both peripheral and central levels. The management of chronic cough starts with exclusion of associated conditions, followed by use of neuromodulators and speech and language therapy.

Clonal hematopoiesis, originally identified as a precursor to hematologic malignancies, has emerged as a significant factor in various nonmalignant diseases. Recent research highlights how somatic mutations in hematopoietic stem cells lead to the expansion of circulating mutated immune cells that exert profound effects on organ function and disease progression. These mutated clones display altered inflammatory profiles and tissue-specific functional consequences, contributing to various diseases including atherosclerotic cardiovascular disease, osteoporosis, heart failure, and neurodegenerative conditions.

Purpose: The monotonous lighting environment in extra-long tunnels often induces mind-wandering in drivers. To address this issue, this study explores effective strategies to optimize tunnel lighting environments by configuring various background colors and special lighting zones to enhance the alertness of young drivers and ensure driving safety.
Methods: A virtual driving simulator was utilized to carry out the experiment.
