Examining Insula-Default Mode Network Functional Connectivity and Its Relationship with Heart Rate Variability.

Background: The Default Mode Network (DMN) is involved in self-referential and emotional processes, while the insula integrates emotional and interoceptive signals. Functional connectivity between the insula and the DMN is proposed to enhance these processes by linking internal bodily states with self-referential thoughts and emotional regulation. Heart Rate Variability (HRV), a measure of parasympathetic regulation of cardiac activity, has been associated with the capacity to regulate autonomic arousal.

100 Years of Insulin: A Historical Perspective.

Background: Diabetes mellitus, a metabolic disease characterized by high blood glucose levels, has increased dramatically in recent years, prompting the need for more affordable diagnoses and treatments.

Objective: This study aimed to conduct a brief historical and theoretical review on the development of insulin.

Methods: Scientific and technological data have been retrieved and analyzed with a focus on the development of the active pharmaceutical ingredient insulin and insulin-based medicines.

Unravelling the transcriptomic symphony of muscle ageing: key pathways and hub genes altered by ageing and caloric restriction in rat muscle revealed by RNA sequencing.

Age-related muscle wasting, sarcopenia is an extensive loss of muscle mass and strength with age and a major cause of disability and accidents in the elderly. Mechanisms purported to be involved in muscle ageing and sarcopenia are numerous but poorly understood, necessitating deeper study. Hence, we employed high-throughput RNA sequencing to survey the global changes in protein-coding gene expression occurring in skeletal muscle with age.

Cardiac Biomarkers in a Brazilian Indigenous Population Exposed to Arboviruses: A Cross-Sectional Study.

Arthropod-borne viral diseases are acute febrile illnesses, sometimes with chronic effects, that can be debilitating and even fatal worldwide, affecting particularly vulnerable populations. Indigenous communities face not only the burden of these acute febrile illnesses, but also the cardiovascular complications that are worsened by urbanization. A cross-sectional study was conducted in an Indigenous population in the Northeast Region of Brazil to explore the association between arboviral infections (dengue, chikungunya, and Zika) and cardiac biomarkers, including cardiotrophin 1, growth differentiation factor 15, lactate dehydrogenase B, fatty-acid-binding protein 3, myoglobin, N-terminal pro-B-type natriuretic peptide, cardiac troponin I, big endothelin 1, and creatine kinase-MB, along with clinical and anthropometric factors.

Effects of Speed-Based Interventions to Reduce Bradykinesia in Individuals with Parkinson's Disease: A Systematic Review Protocol.

Background/objectives: Bradykinesia is considered one of the most disabling motor symptoms in individuals with Parkinson's disease (PD). Speed-based interventions are promising for reducing bradykinesia in this population. This systematic review aims to describe speed-based interventions that have been employed for reducing bradykinesia in individuals with PD and verify their effects.
