Clinical Phenotype of Behavioral-Variant Frontotemporal Dementia Reversed by ECT: A Case Report.

Introduction: Diagnosis of frontotemporal dementia (FTD) remains difficult even in the presence of core clinical and imaging features. Furthermore, disease-modifying treatments are lacking.

Case Presentation: Here, we report a case of a patient with clinical and imaging features of FTD.

Environmental filtering, not dispersal history, explains global patterns of phylogenetic turnover in seed plants at deep evolutionary timescales.

Environmental filtering and dispersal history limit plant distributions and affect biogeographical patterns, but how their relative importance varies across evolutionary timescales is unresolved. Phylogenetic beta diversity quantifies dissimilarity in evolutionary relatedness among assemblages and might help resolve the ecological and biogeographical mechanisms structuring biodiversity. Here, we examined the effects of environmental dissimilarity and geographical distance on phylogenetic and taxonomic turnover for ~270,000 seed plant species globally and across evolutionary timescales.

Observation of E-cadherin adherens junction dynamics with metal-induced energy transfer imaging and spectroscopy.

Epithelial cadherin (E-cad) mediated cell-cell junctions play a crucial role in the establishment and maintenance of tissues and organs. In this study, we employed metal-induced energy transfer imaging and spectroscopy to investigate variations in intermembrane distance during adhesion between two model membranes adorned with E-cad. By correlating the measured intermembrane distances with the distinct E-cad junction states, we probed the dynamic behavior and diversity of E-cad junctions across different binding pathways.

Periodontal health in teeth treated with deep-margin-elevation and CAD/CAM partial lithium disilicate restorations-a prospective controlled trial.

Objectives: This prospective controlled clinical trial aimed to compare periodontal parameters of proximal deep-margin-elevation (DME) restoration margins with supragingival/equigingival restoration margins (control) on the opposite proximal surface of the same tooth.

Materials And Methods: Subgingival one-sided proximal defects (mesial or distal) on (pre-)molars were restored with composite DME and CAD/CAM-manufactured lithium disilicate ceramic partial-coverage restorations. Periodontal parameters (bleeding on probing (BOP), periodontal probing depths (PPD), plaque index (PI)) were recorded after insertion of the ceramic restoration (baseline) and at 1-year recall visit and compared between DME and control on the same tooth (Fisher's exact test and Wilcoxon signed rank test, p < 0.

Towards Treating Multiple Sclerosis Progression.

Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system (CNS). In most patients, the disease starts with an acute onset followed by a remission phase, subsequent relapses and a later transition to steady chronic progression. In a minority of patients, this progressive phase develops from the beginning.

Molecules That Have Rarely Been Studied in Lymphatic Endothelial Cells.

A number of standard molecules are used for the molecular and histological characterization of lymphatic endothelial cells (LECs), including lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1), Podoplanin (D2-40), VEGFR3, Prospero homeobox protein 1 (PROX1), and CD31. The number of molecules whose mutations cause lymphatic malformations or primary congenital lymphedema is considerable, but the majority of these diseases have not yet been characterized at the molecular level. Therefore, there is still considerable scope for molecular and functional studies of the lymphatic vasculature.

Effective Survey Methods for the Elusive Data Deficient Black Flying Squirrel () in Sabah, Malaysia Facilitate First Vocalisation Record.

Flying squirrels are nocturnal, gliding relatives of tree and ground squirrels (order Sciuridae). Despite 49 species existing, literature on Asiatic flying squirrels is scarce, thus they are overlooked in conservation action plans. Recently, three species of giant flying squirrel (, and ) were observed during a nocturnal mammal survey at the Rainforest Discovery Centre (RDC), an Eco centre at the edge of the Kabili-Sepilok forest reserve in Sepilok, Sabah (Malaysia, Borneo).

Photoregulatory functions drive variation in eye coloration across macaque species.

Primates, the most colorful mammalian radiation, have previously served as an interesting model to test the functions and evolutionary drivers of variation in eye color. We assess the contribution of photo-regulatory and communicative functions to the external eye appearance of nine macaque species representing all the branches of their radiation. Macaques' well described social structure and wide geographical distribution make them interesting to explore.

Outcomes of Adjunct Emergent Stenting Versus Mechanical Thrombectomy Alone: The RESCUE-ICAS Registry.

Background: Underlying intracranial stenosis is the most common cause of failed mechanical thrombectomy in patients with acute ischemic stroke with large vessel occlusion. Adjunct emergent stenting is sometimes performed to improve or maintain reperfusion, despite limited data regarding its safety or efficacy.

Methods: We conducted a prospective multicenter observational international cohort study.

Modality-specific and modality-general representations of subjective value in frontal cortex.

Neuroeconomics theories propose that the value associated with diverse rewards or reward-predicting stimuli is encoded along a common reference scale, irrespective of their sensory properties. However, in a dynamic environment with changing stimulus-reward pairings, the brain must also represent the sensory features of rewarding stimuli. The mechanism by which the brain balances these needs-deriving a common reference scale for valuation while maintaining sensitivity to sensory contexts-remains unclear.

A Latent Cardiomyocyte Regeneration Potential in Human Heart Disease.

Background: Cardiomyocytes in the adult human heart show a regenerative capacity, with an annual renewal rate of ≈0.5%. Whether this regenerative capacity of human cardiomyocytes is employed in heart failure has been controversial.

Nonlinear receptive fields evoke redundant retinal coding of natural scenes.

The role of the vertebrate retina in early vision is generally described by the efficient coding hypothesis, which predicts that the retina reduces the redundancy inherent in natural scenes by discarding spatiotemporal correlations while preserving stimulus information. It is unclear, however, whether the predicted decorrelation and redundancy reduction in the activity of ganglion cells, the retina's output neurons, hold under gaze shifts, which dominate the dynamics of the natural visual input. We show here that species-specific gaze patterns in natural stimuli can drive correlated spiking responses both in and across distinct types of ganglion cells in marmoset as well as mouse retina.

A methodological review identified several options for utilizing registries for randomized controlled trials.

Objectives: Registry-based randomized controlled trials (RRCTs) can provide internally valid results in a real-world context at relatively low effort and cost. However, the main characteristics, the extent to which the registry is utilized (eg, proportion of data from registry) and registry-related limitations are not well characterized. This methodological review of RRCTs aims to analyze the trial design features, investigate potential usage options, and identify possible limitations of using registry data for randomized controlled trials (RCTs).

Counseling and disclosure practices in predictive Alzheimer's disease diagnostics: A scoping review.

New possibilities of biomarker-based predictive technologies for Alzheimer's disease (AD) have become more reliable as well as more accessible. Standardized clinical recommendations and guidance for counseling and disclosure in this context are not yet well developed. Our scoping review identified publications from database searches in PubMed, PsycINFO, LIVIVO, and Web of Science.

Collagen crosslinking-induced corneal morphological changes: a three-dimensional light sheet Microscopy-based evaluation.

Stiffness-related eye diseases such as keratoconus require comprehensive visualization of the complex morphological matrix changes. The aim of this study was to use three-dimensional (3D) light sheet fluorescence microscopy (LSFM) to analyze unlabeled corneal tissue samples, qualitatively visualizing changes in corneal stiffness. Isolated porcine corneal tissue samples were treated with either NaCl or 0.

Effect of mechanical stirring on sonoluminescence and sonochemiluminescence.

Light emissions from cavitating liquids serve as a diagnostic tool for chemical activity, bubble collapse conditions, or excited species. Here we demonstrate the influence of mechanical stirring on sonoluminescence (SL) and sonochemiluminescence (SCL) emissions emerging in the presence of dissolved sodium salts and luminol in different sonicated liquids. In the systems investigated, driven in the 20-40 kHz range, stirring can change the spatial distribution of blue/white broadband SL emissions and of the orange sodium D-line emission, as well as their relative intensities.

Transcriptional profiling of the M. complexus in naked neck chickens suggest a direct pleiotropic effect of GDF7 on feathering and reduced hatchability.

Background: The locus for naked neck (Na) in chickens reduces feather coverage and leads to increased heat dissipation from the body surface resulting in better adaptability to hot conditions. However, the Na gene is linked to significantly lower hatchability due to an increased late embryonic mortality. It has been argued that the causative gene GDF7 may have a direct pleiotropic effect on hatchability via its effect on muscle development.

Machine learning adjusted sequential CUSUM-analyses are superior to cross-sectional analysis of excess mortality after surgery.

Background: The assessment of clinical outcome quality, particularly in surgery, is crucial for healthcare improvement. Traditional cross-sectional analyses often fall short in timely and systematic identification of clinical quality issues. This study explores the efficacy of machine learning adjusted sequential CUSUM (Cumulative Sum) analyses in monitoring post-surgical mortality.

Dynamics of switching processes: general results and applications in intermittent active motion.

Systems switching between different dynamical phases is a ubiquitous phenomenon. The general understanding of such a process is limited. To this end, we present a general expression that captures fluctuations of a system exhibiting a switching mechanism.

Enhancing patient activation: a controlled implementation study of an interprofessional evidence-based counseling program for complementary and integrative healthcare in cancer patients ('CCC-Integrativ').

Complementary and integrative healthcare (CIH) is increasingly recognized as a valuable approach to empowering and activating cancer patients. Studies have shown that higher patient activation is positively associated with improved health outcomes and reduced healthcare costs. The CCC-Integrativ study aimed to assess the implementation of an evidence-based counseling service on CIH at four Comprehensive Cancer Centers (CCC) in Germany.

Neural correlates of sensorimotor adaptation: Thalamic contributions to learning from sensory prediction error.

Understanding the neural mechanism of sensorimotor adaptation is essential to reveal how the brain learns from errors, a process driven by sensory prediction errors. While the previous literature has focused on cortical and cerebellar changes, the involvement of the thalamus has received less attention. This functional magnetic resonance imaging study aims to explore the neural substrates of learning from sensory prediction errors with an additional focus on the thalamus.

Lithological Controls on Soil Aggregates and Minerals Regulate Microbial Carbon Use Efficiency and Necromass Stability.

Microbial carbon (C) use efficiency (CUE) drives soil C formation, while physical-chemical protection stabilizes subsequent microbial necromass, both shaped by soil aggregates and minerals. Soils inherit many properties from the parent material, yet the influence of lithology and associated soil geochemistry on microbial CUE and necromass stabilization remains unknow. Here, we quantified microbial CUE in well-aggregated bulk soils and crushed aggregates, as well as microbial necromass in bulk soils and the mineral-associated organic matter fraction, originating from carbonate-containing (karst) and carbonate-free (clastic rock, nonkarst) parent materials along a broad climatic gradient.

Cognitive reserve against Alzheimer's pathology is linked to brain activity during memory formation.

The cognitive reserve (CR) hypothesis posits that individuals can differ in how their brain function is disrupted by pathology associated with aging and neurodegeneration. Here, we test this hypothesis in the continuum from cognitively normal to at-risk stages for Alzheimer's Disease (AD) to AD dementia using longitudinal data from 490 participants of the DELCODE multicentric observational study. Brain function is measured using task fMRI of visual memory encoding.
