Core Components of Cardiac Rehabilitation Programs: 2024 Update: A Scientific Statement From the American Heart Association and the American Association of Cardiovascular and Pulmonary Rehabilitation: Endorsed by the American College of Cardiology.

The science of cardiac rehabilitation and the secondary prevention of cardiovascular disease has progressed substantially since the most recent American Heart Association and American Association of Cardiovascular and Pulmonary Rehabilitation update on the core components of cardiac rehabilitation and secondary prevention programs was published in 2007. In addition, the advent of new care models, including virtual and remote delivery of cardiac rehabilitation services, has expanded the ways that cardiac rehabilitation programs can reach patients. In this scientific statement, we update the scientific basis of the core components of patient assessment, nutritional counseling, weight management and body composition, cardiovascular disease and risk factor management, psychosocial management, aerobic exercise training, strength training, and physical activity counseling.

Study of endophytic fungi of Ipomoea pes-caprae reveals the superiority of in situ plant conservation over ex situ conservation from a mycological view.

In nature conservation, ex situ and in situ conservation strategies are discussed for protecting endangered species of plants and animals. However, the impacts of these strategies on the microbes associated with these species are rarely considered. In our study, we chose the endophytic fungi of the pantropical creeping plant Ipomoea pes-caprae as representative coastal plant in two natural coastal populations and two botanical gardens in Taiwan as collection sites in order to investigate the potential effect of ex situ plantation on the biodiversity of microbes intimately associated with this plant.

Discovery of a potential open ocean nursery for the endangered shortfin mako shark in a global fishing hotspot.

Populations of large pelagic sharks are declining worldwide due to overfishing. Determining the overlap between shark populations and fishing activities is important to inform conservation measures. However, for many threatened sharks the whereabouts of particularly vulnerable life-history stages - such as pregnant females and juveniles - are poorly known.

Development of a broad-spectrum epitope-based vaccine against Streptococcus pneumoniae.

Streptococcus pneumoniae (SPN) is a significant pathogen causing pneumonia and meningitis, particularly in vulnerable populations like children and the elderly. Available pneumonia vaccines have limitations since they only cover particular serotypes and have high production costs. The emergence of antibiotic-resistant SPN strains further underscores the need for a new, cost-effective, broad-spectrum vaccine.

Trials and tribulations: a qualitative exploration of researcher perspectives on navigating the challenges of health system implementation research.

Objective: While researchers are crucial to the successful delivery of implementation trials, their perspectives are rarely captured in the evaluation of these trials. This qualitative study aimed to capture the experiences of a small research team coordinating a large, multisite implementation trial (the Hide and Seek Project) in the Australian healthcare setting.

Design: A qualitative approach was used, whereby members of the Hide and Seek Project research team were invited to take part in semistructured focus groups led by an external facilitator.

Effects of described demonstrator ability on brain and behavior when learning from others.

Observational learning enables us to make decisions by watching others' behaviors. The quality of such learning depends on the abilities of those we observe, but also on our beliefs about those abilities. We have previously demonstrated that observers learned better from demonstrators described as high vs.

Encoding of cerebellar dentate neuron activity during visual attention in rhesus macaques.

The role of cerebellum in controlling eye movements is well established, but its contribution to more complex forms of visual behavior has remained elusive. To study cerebellar activity during visual attention we recorded extracellular activity of dentate nucleus (DN) neurons in two non-human primates (NHPs). NHPs were trained to read the direction indicated by a peripheral visual stimulus while maintaining fixation at the center, and report the direction of the cue by performing a saccadic eye movement into the same direction following a delay.

Combined effects of global DNA methylation, blood lead and total urinary arsenic levels on developmental delay in preschool children.

DNA methylation is a critical step in brain development, 5-Methyl-2'-deoxycytidine (5mdC) is one of the global DNA methylation markers. Arsenic and lead exposures have been associated with neurotoxicity, which may be linked to epigenetic changes. Our research sought to investigate the correlation between 5mdC and developmental delay (DD) among preschoolers.

Random noise promotes slow heterogeneous synaptic dynamics important for robust working memory computation.

Recurrent neural networks (RNNs) based on model neurons that communicate via continuous signals have been widely used to study how cortical neural circuits perform cognitive tasks. Training such networks to perform tasks that require information maintenance over a brief period (i.e.

Estrogen Deficiency alters Vascularization and Mineralization dynamics: insight from a novel 3D Humanized and Vascularized Bone Organoid Model.

Osteoporosis is not merely a disease of bone loss but also involves changes in the mineral composition of the bone that remains. studies have investigated these changes and revealed that estrogen deficiency alters osteoblast mineral deposition, osteocyte mechanosensitivity and osteocyte regulation of osteoclastogenesis. During healthy bone development, vascular cells stimulate bone mineralization via endochondral ossification, but estrogen deficiency impairs vascularization.

Proteomic Profiling Reveals Alterations in Metabolic and Cellular Pathways in Severe Obesity and Following Metabolic Bariatric Surgery.

In this study, we investigated the impact of bariatric surgery on the adipose proteome to better understand the metabolic and cellular mechanisms underlying weight loss following the procedure. A total of 46 patients with severe obesity were included, with samples collected both before and after bariatric surgery. Additionally, 15 healthy, non-obese individuals who did not undergo surgery served as controls and were studied once.

A power dependence model of the impact of leader impostorism on supervisor support and undermining: The moderating role of power distance.

Leaders, often perceived as possessing exceptional confidence and competence, are not immune to feelings of self-doubt. Leader impostorism describes the experience that one's attributes, experiences, skills, and abilities fall short of the standards expected in the leadership role, resulting in a sense of deception in fulfilling leadership responsibilities. While existing research has examined the antecedents and individual outcomes of leader impostorism, its implications for leaders' treatment of subordinates remain largely unexplored.

Hunting glioblastoma recurrence: glioma stem cells as retrospective targets.

Glioblastoma (GBM) remains one of the most aggressive and treatment-resistant brain malignancies in adults. Standard approaches, including surgical resection followed by adjuvant radio- and chemotherapy with temozolomide, provide only transient control, as GBM frequently recurs due to its infiltrative nature and the presence of therapy-resistant subpopulations such as glioma stem cells (GSCs). GSCs, with their quiescent state and robust resistance mechanisms, evade conventional therapies, contributing significantly to relapse.

Can microbiota gut-brain axis reverse neurodegenerative disorders in human?

The trillions of microbial populations residing in the gut have recently shown that they can be used as a remedy for various diseases. The gut microbiota-brain-axis interface is one unique pathway that the microbiota demonstrates its medicinal value. This medicinal value is further seen when there is a decline in gut microbial diversity (dysbiosis).

Dissection of type 2 diabetes: a genetic perspective.

Diabetes is a leading cause of global mortality and disability, and its economic burden is substantial. This Review focuses on type 2 diabetes, which makes up 90-95% of all diabetes cases. Type 2 diabetes involves a progressive loss of insulin secretion often alongside insulin resistance and metabolic syndrome.

Electron-Donating Zr Induces Suppressed Ru Over-Oxidation and Accelerated Deprotonation Process Toward Efficient and Durable Water Electrolysis.

The scarcity of cost-effective and durable iridium-free anode electrocatalysts for the oxygen evolution reaction (OER) poses a significant challenge to the widespread application of the proton exchange membrane water electrolyzer (PEMWE). To address the electrochemical oxidation and dissolution issues of Ru-based electrocatalysts, an electron-donating modification strategy is developed to stabilize WRuO under harsh oxidative conditions. The optimized catalyst with a low Zirconium doping (Zr, 1 wt.

The inhibition of human microsomal prostaglandin E (PGE) synthase-1 (mPGES-1) is a promising therapeutic modality for developing next-generation anti-inflammatory medications. In this study, we present novel 2-phenylbenzothiazole derivatives featuring heteroaryl sulfonamide end-capping substructures as inhibitors of human mPGES-1, with IC values in the range of 0.72-3.

Testing hypotheses of skull function with comparative finite element analysis: three methods reveal contrasting results.

Comparative finite element analysis involves standardising aspects of models to test equivalent loading scenarios across species. However, regarding feeding biomechanics of the vertebrate skull, what is considered "equivalent" can depend on the hypothesis. Using 13 diversely-shaped skulls of marsupial bettongs and potoroos (Potoroidae), we demonstrate that scaling muscle forces to standardise specific aspects of biting mechanics can produce clearly opposing comparisons of stress or strain that are differentially suited to address specific kinds of hypotheses.
