Photobiomodulation (PBM) therapy, a non-thermal light therapy using nonionizing light sources, has shown therapeutic potential across diverse biological processes, including aging and age-associated diseases. In 2023, scientists from the National Institute on Aging (NIA) Intramural and Extramural programs convened a workshop on the topic of PBM to discuss various proposed mechanisms of PBM action, including the stimulation of mitochondrial cytochrome C oxidase, modulation of cell membrane transporters and receptors, and the activation of transforming growth factor-β1. They also reviewed potential therapeutic applications of PBM across a range of conditions, including cardiovascular disease, retinal disease, Parkinson's disease, and cognitive impairment.

The goal of the current study was to learn about the role of cerebral mitochondrial function on cognition. Based on established cognitive neuroscience, clinical neuropsychology, and cognitive aging literature, we hypothesized mitochondrial function within a focal brain region would map onto cognitive behaviors linked to that brain region. To test this hypothesis, we used phosphorous (P) magnetic resonance spectroscopy (MRS) to derive indirect markers of mitochondrial function and energy metabolism across two regions of the brain (bifrontal, left temporal).

Directly involved in the "suck-and-spit" physiology, female mosquito salivary glands (SGs) primarily imbibe blood for egg development and release anticoagulants to keep blood flowing. Indirectly involved, mosquitoes can uptake arboviruses during blood feeding from a viremic host. This research examined the presence of the filamentous cytoplasmic contractile protein (F-actin) and heparan sulfate proteoglycan (HSPG), in the female mosquito SGs.

Background: Social determinants of health (SDOH) cause significant burden on individuals living with acute and chronic disease. There are meaningful data to support screening for social needs, yet implementation limitations exist in the clinical setting. Incorporating SDOH education into nurse practitioner (NP) curriculum provides a framework for bringing these concepts into clinical practice.

Objective: Apathy, a motivational disorder, is common in Parkinson's disease (PD) and often misdiagnosed as depression. Use of selective serotonin reuptake inhibitors (SSRIs) has been associated with increased apathy in adolescents and adults with depression. Based on observations that serotonin may downregulate dopaminergic systems, we examined the relationship between apathy and SSRI use in individuals with PD.

Cardiovascular complications related to cancer therapies are broad and variable in onset. These complications are the leading cause of non-cancer related morbidity and mortality in childhood cancer survivors and can also impact ongoing cancer treatment. Despite this understanding, dedicated cardio-oncology programs are lacking in pediatric cardiology.

To report the results of 'responsive' deep brain stimulation (DBS) for Tourette syndrome (TS) in a National Institutes of Health funded experimental cohort. The use of 'brain derived physiology' as a method to trigger DBS devices to deliver trains of electrical stimulation is a proposed approach to address the paroxysmal motor and vocal tic symptoms which appear as part of TS. Ten subjects underwent bilateral staged DBS surgery and each was implanted with bilateral centromedian thalamic (CM) region DBS leads and bilateral M1 region cortical strips.

Article Synopsis
  • - The study examines a modified clinical classification for pediatric patients with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD), focusing on conditions like atrial septal defects (ASD) and transposition of the great arteries (TGA) using data from the TOPP-1 registry.
  • - 223 out of 531 patients in the registry had PAH-CHD, categorized into groups based on their conditions; 193 were classified, revealing a distribution across predefined categories without any significant survival differences between the groups compared to idiopathic PAH patients.
  • - The conclusions suggest that the modified classification better suits pediatric PAH-CHD cases, though it indicates that some patients without shunts are still un
