Article Synopsis
  • SUPPORT is a self-supervised learning method designed to effectively remove Poisson-Gaussian noise from voltage imaging data by leveraging the spatial and temporal relationships between pixel values.
  • The method utilizes a convolutional neural network that accounts for spatiotemporal dependencies, allowing it to denoise images even when adjacent frames lack useful predictive information.
  • Experimental results demonstrate that SUPPORT not only accurately denoises voltage imaging data but also preserves the essential dynamics of the imaged scene.

Neuroimage Analytics Laboratory and Biggs Institute Neuroimaging Core, Glenn Biggs Institute for Neurodegenerative Disorders, University of Texas Health Science Center at San Antonio, San Antonio, TX, USA; Biomedical Image Analytics Division, Research Imaging Institute, University of Texas Health Science Center at San Antonio, San Antonio, TX, USA. Electronic address:

Deep neural networks currently provide the most advanced and accurate machine learning models to distinguish between structural MRI scans of subjects with Alzheimer's disease and healthy controls. Unfortunately, the subtle brain alterations captured by these models are difficult to interpret because of the complexity of these multi-layer and non-linear models. Several heatmap methods have been proposed to address this issue and analyze the imaging patterns extracted from the deep neural networks, but no quantitative comparison between these methods has been carried out so far.

The molecular evolution of spermatogenesis across mammals.

Nature

January 2023

Center for Molecular Biology (ZMBH), DKFZ-ZMBH Alliance, Heidelberg University, Heidelberg, Germany.

The testis produces gametes through spermatogenesis and evolves rapidly at both the morphological and molecular level in mammals, probably owing to the evolutionary pressure on males to be reproductively successful. However, the molecular evolution of individual spermatogenic cell types across mammals remains largely uncharacterized. Here we report evolutionary analyses of single-nucleus transcriptome data for testes from 11 species that cover the three main mammalian lineages (eutherians, marsupials and monotremes) and birds (the evolutionary outgroup), and include seven primates.

The position presented in this article draws on the professional insights of the authors, reflecting on issues of global political importance in culture and migration mental health. As institutional theory perspectives continue to develop, solutions to complex social problems such as racism require embodied knowledge if the lines of authority and basic occupational routines are to be meaningfully renegotiated. Embodied knowledge is socially situated and self-reflexive and reflects cumulative and marginalized experiences that contribute to a better understanding of institutional racism and the social construction of .

Introduction: Mechanical circulatory support (MCS) devices are increasingly used as a treatment option in resuscitation or in patients with cardiogenic shock (CS). Prophylactic implantation in high-risk percutaneous coronary interventions (HRPCI) is another upcoming indication. The i-cor ECG-synchronized cardiac assist device combines the hemodynamic support of a veno-arterial extracorporeal membrane oxygenation (VA-ECMO) with the ability to generate a pulsatile flow and thus decreasing adverse effects of VA-ECMO on myocardial function.

It is largely unknown whether cancer patients seen in routine care show ventricular arrhythmias in 24 h electrocardiograms (ECGs), and whether when they are detected they carry prognostic relevance. We included 261 consecutive cancer patients that were referred to the department of cardiology for 24 h ECG examination and 35 healthy controls of similar age and sex in the analysis. To reduce selection bias, cancer patients with known left ventricular ejection fraction <45% were not included in the analysis.

Early adversity influences brain development and emerging behavioral phenotypes relevant for psychiatric disorders. Understanding the effects of adversity before and after conception on brain development has implications for contextualizing current public health crises and pervasive health inequities. The use of functional magnetic resonance imaging (fMRI) to study the brain at rest has shifted understanding of brain functioning and organization in the earliest periods of life.

Obesity and type 2 diabetes are nutrition-related conditions associated with lung function impairment and pulmonary diseases; however, the underlying pathomechanisms are incompletely understood. Pulmonary surfactant is essential for lung function, and surfactant synthesis by AT2 (alveolar epithelial type 2) cells relies on nutrient uptake. We hypothesized that dietary amounts of carbohydrates or fat affect surfactant homeostasis and composition.

Differential clusterization of soluble and extracellular vesicle-associated cytokines in myocardial infarction.

Sci Rep

December 2020

Section On Intercellular Interactions, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD, 20892, USA.

A proinflammatory dysregulation of cytokine release is associated with various diseases, in particular with those of infectious etiology, as well as with cardiovascular diseases (CVD). We showed earlier that cytokines are released in two forms, soluble and in association with extracellular vesicles (EVs). Here, we investigated the patterns of expression and clustering of soluble and EV-associated cytokines in patients with ST-elevation myocardial infarction (STEMI).

Article Synopsis
  • A study looked at cancer patients with lung, colon, or pancreatic cancer to see if heart problems, like irregular heartbeats, affect their survival.* -
  • Out of 120 cancer patients studied, many (80%) died within about 21 months, and a specific type of heart issue called non-sustained ventricular tachycardia was found to be common among them.* -
  • The research suggests that these heart problems could help predict which cancer patients might not live as long, indicating that doctors might need to pay more attention to heart health in these patients.*

The role of TPH2 variant rs4570625 in shaping infant attention to social signals.

Infant Behav Dev

August 2020

The FinnBrain Birth Cohort Study, Turku Brain and Mind Center, Institute of Clinical Medicine, University of Turku, Finland; Turku University Hospital and University of Turku, Department of Child Psychiatry, Finland.

TPH2, the rate-limiting enzyme in the synthesis of serotonin, has been connected to several psychiatric outcomes. Its allelic variant, rs4570625, has been found to relate to individual differences in cognitive and emotion regulation during infancy with T-carriers of rs4570625 showing a relatively heightened attention bias for fearful faces. A significant gene-environment interaction was also reported with the T-carriers of mothers with depressive symptoms showing the highest fear bias.

The diversity of synaptotagmin isoforms.

Curr Opin Neurobiol

August 2020

German Center for Neurodegenerative Diseases, Charité University of Medicine - Berlin, 10117 Berlin, Germany. Electronic address:

The synaptotagmin family of molecules is known for regulating calcium-dependent membrane fusion events. Mice and humans express 17 synaptotagmin isoforms, where most studies have focused on isoforms 1, 2, and 7, which are involved in synaptic vesicle exocytosis. Recent work has highlighted how brain function relies on additional isoforms, with roles in postsynaptic receptor endocytosis, vesicle trafficking, membrane repair, synaptic plasticity, and protection against neurodegeneration, for example, in addition to the traditional concept of synaptotagmin-mediated neurotransmitter release - in neurons as well as glia, and at different timepoints.

Introduction: Over the past few years, the share of foreign national prisoners in the European and American justice systems has increased at a disproportionately high rate, yet studies on mental health issues among this diverse group are rare. Recent research suggests a range of factors leading to mental health vulnerability in foreign national prisoners, including language barriers, isolation, cultural misunderstanding, and legal standing. Relevant findings of topic-related studies indicate that under-referral to mental health services due to missed or misinterpreted symptoms is a major risk for foreign national prisoners.
