Aging is the main risk factor for Parkinson's disease (PD), yet our understanding of how age-related mechanisms contribute to PD pathophysiology remains limited. We conducted a longitudinal analysis of blood samples from the Parkinson's Progression Markers Initiative cohort to investigate DNA damage in PD. Patients with PD exhibited disrupted DNA repair pathways and biased suppression of longer transcripts, indicating age-related, transcription-stalling DNA damage.

Sleep dysfunction is dominant in patients on oral dopamine replacement therapies as nighttime therapy is suboptimal and often not attempted. Non oral infusion-based Parkinson's disease (PD) therapies, transdermal therapies, as well as deep brain stimulation (DBS) of the subthalamic nucleus (STN) bridge this gap and provide nighttime cover in most cases in PD. DBS of the STN also show significant improvement in PD sleep scale scores and improvement in sleep quality.

Parkinson's disease is a syndrome with many clinical presentations. It is often dominated by visible motor symptoms; however, specific nonmotor features, such as cognitive dysfunction, sleep dysfunction, pain, apathy, dysautonomia, depression, and anxiety, enrich the clinical picture significantly. Proposed non-motor phenotypes segregate to central cholinergic, serotonergic, or noradrenergic dysfunctions, and clinical and biomarker-driven studies support these subtypes.

Comparatively high excitability of myelinated fibres suggests that they represent a major mediator of deep brain stimulation effects. Such effects can be modelled using different levels of abstraction, ranging from simple electric field estimates to complex multicompartment axon models. In this study, we explored three metrics to evaluate axonal activation: electric field magnitudes, electric field projections and pathway activation modelling.

Squamous cell lung carcinoma (SqCC) is the second most common histological subtype of lung cancer. Besides tumor-initiating and promoting DNA, RNA, and epigenetic alterations, aberrant cell metabolism is a hallmark of carcinogenesis. This study aimed to identify SqCC-specific key regulators that could eventually be used as new anticancer targets.

Aging is a major risk factor for neurodegenerative diseases associated with protein aggregation, including Huntington's disease and amyotrophic lateral sclerosis (ALS). Although these diseases involve different aggregation-prone proteins, their common late onset suggests a link to converging changes resulting from aging. In this study, we found that age-associated hyperactivation of EPS8/RAC signaling in Caenorhabditis elegans promotes the pathological aggregation of Huntington's disease-related polyglutamine repeats and ALS-associated mutant FUS and TDP-43 variants.

Path integration, the ability to track one's position using self-motion cues, is critically dependent on the grid cell network in the entorhinal cortex, a region vulnerable to early Alzheimer's disease pathology. In this study, we examined path integration performance in individuals with subjective cognitive decline (SCD), a group at increased risk for Alzheimer's disease, and healthy controls using an immersive virtual reality task. We developed a Bayesian computational model to decompose path integration errors into distinct components.

Introduction: As part of the German Medical Informatics Initiative (MII) and Network University Medicine (NUM), a central research terminology service (TS) is provided by the Service Unit Terminology Services (SU-TermServ). This HL7 FHIR-based service depends on the timely and comprehensive availability of FHIR terminology resources to provide the necessary interactions for the distributed MII/NUM infrastructure. While German legislation has recently instituted a national terminology service for medical classifications and terminologies, the scope of the MII and NUM extends beyond routine patient care, encompassing the need for supplementary or specialized services and terminologies that are not commonly utilized elsewhere.

Introduction: Mapping local medical data assets to international data standards such as medical ontology SNOMED CT fosters data harmonization and, thereby, global progress in medical research. Since its intense resource requirements often hinder manual SNOMED CT mapping, automated mapping tools such as MedCAT have been developed. We investigated how the formulation of study variable names (VNs) influences the efficacy and accuracy of the SNOMED CT concepts identified by MedCAT.

An animal's feeding state changes its behavioral priorities and thus influences even nonfeeding-related decisions. How the feeding state information is transmitted to nonfeeding-related circuits and what circuit mechanisms are involved in biasing nonfeeding-related decisions remain open questions. By combining calcium imaging, neuronal manipulations, behavioral analysis and computational modeling, we determined that the competition between different aversive responses to mechanical cues is biased by changes in the feeding state.

Introduction: Preterm infants, particularly those born before 29 weeks of gestation, are at increased risk of developing bronchopulmonary dysplasia (BPD) and other complications of prematurity. Substantial evidence suggests that respiratory tract colonisation with species significantly contributes to pulmonary inflammation, impaired lung function and subsequent lung disease especially in very immature infants. Moreover, exposure has been implicated in the pathogenesis of other inflammation-related sequelae of prematurity.
