The neurodegenerative progression of Parkinson's disease affects brain structure and function and, concomitantly, alters the topological properties of brain networks. The network alteration accompanied by motor impairment and the duration of the disease has not yet been clearly demonstrated in the disease progression. In this study, we aim to resolve this problem with a modeling approach using the reduced Jansen-Rit model applied to large-scale brain networks derived from cross-sectional MRI data.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.
Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.

Background: Recurrent attacks in neuromyelitis optica spectrum disorders (NMOSDs) or myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can lead to severe disability. We aimed to analyse the real-world use of immunotherapies in patients with NMOSD and MOGAD, focusing on changes in treatment strategies, effects on attack rates (ARR) and risk factors for attacks.
Methods: This longitudinal registry-based cohort study included 493 patients (320 with aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive NMOSD (65%), 44 with AQP4-IgG seronegative NMOSD (9%) and 129 MOGAD (26%)) with 1247 treatments from 19 German and one Austrian centre from the registry of the neuromyelitis optica study group (NEMOS).

Introduction: Interim analysis of the long-term safety and effectiveness of canakinumab, at a patient level, in the mevalonate kinase deficiency/hyperimmunoglobulin-D syndrome (MKD/HIDS) cohort of the RELIANCE registry.
Methods: From June 2018, the RELIANCE registry enrolled paediatric (aged ≥ 2 years) and adult patients (aged ≥ 18 years) with MKD/HIDS who were receiving canakinumab as part of their routine medical care. Safety, physician- and patient-reported measures of disease activity and dosing patterns were evaluated at baseline and every 6 months until end-of-study visit.

Photocaged compounds are chemical conjugates that are designed to release an active molecule upon exposure to light of a specific wavelength. In recent years, photocaged inducer molecules such as caged isopropyl β-D-1-thiogalactopyranoside (cIPTG) have been increasingly used as a powerful tool for light-driven gene expression in bacteria, allowing researchers to precisely and noninvasively tune the expression of specific target genes. In this chapter, we present a guideline for the synthesis of 6-nitropiperonyl photocaged IPTG (NP-cIPTG) as well as its in vivo application as an optochemical on-switch of gene transcription in Escherichia coli and other bacteria.

Malaria continues to pose a significant burden on populations in endemic areas and requires innovative treatment options. Here, we report the synthesis and preclinical evaluation of the novel 3-hydroxypropanamidine (HPA) , which shows excellent antiplasmodial activity against drug-sensitive and -resistant strains. Moreover, in various human cell lines, the compound shows no cytotoxicity and excellent parasite selectivity.

Background: The timing of coronary angiography in patients with successfully resuscitated out-of-hospital cardiac arrest and missing ST-segment elevations on the electrocardiogram has been investigated in 2 large randomized controlled trials, TOMAHAWK (Angiography After Out-of-Hospital Cardiac Arrest Without ST-Segment Elevation) and COACT (Coronary Angiography After Cardiac Arrest Trial). Both trials found neutral results for immediate vs delayed/selective coronary angiography on short-term all-cause mortality. The TOMAHAWK trial showed a tendency towards harm with immediate coronary angiography, though not statistically significant with traditional frequentist methods.

Background: Preterm infants face challenges in their suck-swallow-breathe coordination leading to an increased risk of aspiration. Key components of the swallowing process are present around 34 to 35 weeks postmenstrual age (PMA), but preterm infants fatigue early affecting timing, quality and efficiency in swallowing and prolonging breathing pauses. Feeding strategies need to address these specific challenges in suck-swallow-breathe coordination.

The MICOS complex, essential for cristae organization, comprises MIC10 and MIC60 subcomplexes, with MIC13 as a crucial subunit. mutations cause severe mitochondrial hepato-encephalopathy, cristae defects, and MIC10-subcomplex loss. We demonstrate that depletion of the mitochondrial protease YME1L in KO stabilizes MIC10-subcomplex, restoring MIC60-MIC10 interaction and crista junction (CJ) defects, indicating MIC13 is crucial for MIC10-subcomplex stabilization rather than MIC60-MIC10 bridging.

Background: Physical inactivity and tobacco smoking remain the leading causes of morbidity and mortality worldwide. In Germany, smoking prevalence is high at around 30%, and only 45% achieve the WHO recommendation for physical activity (PA). Understanding how smoking and physical inactivity co-occur can inform interventions targeting these behaviours.

Pericytes respond dynamically to vascular challenges; however, how they manifest under the continuous strain of hypertension has not been elucidated.
Methods And Results: In this study, we characterized pericyte behavior alongside hypertensive states in the spontaneously hypertensive stroke-prone rat model, focusing on their phenotypic and metabolic transformation.

Chronic back pain (CBP) is a global health concern with significant societal and economic burden. While various predictors of back pain chronicity have been proposed, including demographic and psychosocial factors, neuroimaging studies have pointed to brain characteristics as predictors of CBP. However, large-scale, multisite validation of these predictors is currently lacking.

Alga-dominated geothermal spring communities in Yellowstone National Park (YNP), USA, have been the focus of many studies, however, relatively little is known about the composition and community interactions which underpin these ecosystems. Our goal was to determine, in three neighboring yet distinct environments in Lemonade Creek, YNP, how cells cope with abiotic stressors over the diurnal cycle. All three environments are colonized by two photosynthetic lineages, and , both of which are extremophilic Cyanidiophyceae red algae.

The sustainability of maize cultivation would benefit tremendously from early sowing, but is hampered by low temperatures during early development in temperate climates. We show that allelic variation within the gene encoding subunit M of the NADH-dehydrogenase-like (NDH) complex (ndhm1) in a European maize landrace affects several quantitative traits that are relevant during early development in cold climates through NDH-mediated cyclic electron transport around photosystem I, a process crucial for photosynthesis and photoprotection. Beginning with a genome-wide association study for maximum potential quantum yield of photosystem II in dark-adapted leaves (Fv/Fm), we capitalized on the large phenotypic effects of a hAT transposon insertion in ndhm1 on multiple quantitative traits (early plant height [EPH], Fv/Fm, chlorophyll content, and cold tolerance) caused by the reduced protein levels of NDHM and associated NDH components.
