Inflammatory stimuli impact on cellular uptake and biodistribution of perfluorocarbon nanoemulsions.

Intravenously administered perfluorocarbon nanoemulsion (PFC) are taken up by phagocytic immune cells which enables the non-invasive visualization of inflammatory hot spots by combined 1H/19F magnetic resonance imaging (MRI). However, little is known about the influence of inflammatory stimuli on cellular uptake and biodistribution of PFCs. Here, we systematically investigated the impact of inflammation induced by subcutaneous implantation of Matrigel/lipopolysaccharide (Matrigel/LPS) or myocardial infarction (MI; 50 minutes ischemia reperfusion) on PFC-uptake and biodistribution in C57BL/6J mice.

Trained innate immunity: Concept, nomenclature, and future perspectives.

During the past decade, compelling evidence has accumulated demonstrating that innate immune cells can mount adaptive characteristics, leading to long-term changes in their function. This de facto innate immune memory has been termed trained immunity. Trained immunity, which is mediated through extensive metabolic rewiring and epigenetic modifications, has important effects in human diseases.

Combined application of biochar and peatmoss for mitigation of drought stress in tobacco.

Drought poses a significant ecological threat that limits the production of crops worldwide. The objective of this study to examine the impact of soil applied biochar (BC) and peatmoss (PM) on the morpho-biochemical and quality traits of tobacco plants under drought conditions. In the present experiment work, a pot trial was conducted with two levels of drought severity (~ well-watered 75 ± 5% field capacity) and severe drought stress (~ 35 ± 5% field capacity), two levels of peatmoss (PM) @ 5% [PM+ (with peatmoss) and PM- (without peatmoss)] and three levels of rice straw biochar (BC = no biochar; BC = 150 mg kg; and BC = 300 mg kg of soil) in tobacco plants.

Long-read transcriptome sequencing of CLL and MDS patients uncovers molecular effects of mutations.

Mutations in splicing factor 3B subunit 1 () frequently occur in patients with chronic lymphocytic leukemia (CLL) and myelodysplastic syndromes (MDSs). These mutations have different effects on the disease prognosis with beneficial effect in MDS and worse prognosis in CLL patients. A full-length transcriptome approach can expand our knowledge on mutation effects on RNA splicing and its contribution to patient survival and treatment options.

Serotonergic modulation of swallowing in a complete fly vagus nerve connectome.

How the body interacts with the brain to perform vital life functions, such as feeding, is a fundamental issue in physiology and neuroscience. Here, we use a whole-animal scanning transmission electron microscopy volume of Drosophila to map the neuronal circuits that connect the entire enteric nervous system to the brain via the insect vagus nerve at synaptic resolution. We identify a gut-brain feedback loop in which Piezo-expressing mechanosensory neurons in the esophagus convey food passage information to a cluster of six serotonergic neurons in the brain.

Chromosome-level genome assembly of the morabine grasshopper Vandiemenella viatica19.

Morabine grasshoppers in the Vandiemenella viatica species group, which show karyotype diversity, have been studied for their ecological distribution and speciation in relation to their genetic and chromosomal diversity. They are good models for studying sex chromosome evolution as "old" and newly emerged sex chromosomes co-exist within the group. Here we present a reference genome for the viatica19 chromosomal race, that possesses the ancestral karyotype within the group.

Phyto-assisted synthesis of zinc oxide nanoparticles using Bauhinia variegata buds extract and evaluation of their multi-faceted biological potentials.

Zinc oxide nanoparticles have wide range biological, biomedical and environmental applications. However, traditional nanofabrication of ZnONPs uses various toxic chemicals and organic solvents which limit their bio-applications. To overcome this hurdle, Bauhinia variegata derived buds extract was utilized to fabricate ZnONPs.

Influence of implant strategy on the transition from temporary left ventricular assist device to durable mechanical circulatory support.

Objectives: Bridging from a temporary microaxial left ventricular assist device (tLVAD) to a durable left ventricular assist device (dLVAD) is playing an increasing role in the treatment of terminally ill patients with heart failure. Scant data exist about the best implant strategy. The goal of this study was to analyse differences in the dLVAD implant technique and effects on patient outcomes.

The severity of respiratory syncytial virus infection in children during the SARS-CoV-2/COVID-19 pandemic: A nationwide study of 11,915 cases in Germany.

Purpose: Respiratory syncytial virus (RSV) infection is a major cause of childhood hospitalization. The COVID-19 pandemic has disrupted the usual seasonal pattern of RSV, resulting in high activity during the off-season. This study aims to evaluate the effects of the pandemic on the severity of RSV infections.

Prognostic value of Alzheimer's disease plasma biomarkers in the oldest-old: a prospective primary care-based study.

Background: Blood-based biomarkers offer a promising, less invasive, and more cost-effective alternative for Alzheimer's disease screening compared to cerebrospinal fluid or imaging biomarkers. However, they have been extensively studied only in memory clinic-based cohorts. We aimed to validate them in a more heterogeneous, older patient population from primary care.

Effectiveness of structured, multidisciplinary long-term care for pediatric cancer survivors: protocol of the multicenter, randomized-controlled AELKI study.

Background: In Germany, around 2.250 children and adolescents are diagnosed with cancer each year. Despite generally positive long-term survival rates, many patients must cope with late effects of the disease and its treatment.

Percutaneous Edge-to-Edge Repair for Tricuspid Regurgitation: 3-Year Outcomes From the TRILUMINATE Study.

Background: Tricuspid regurgitation (TR) is a common valve disease that has a significant impact on patients' quality of life.

Objectives: This study sought to report the final 3-year outcomes of tricuspid transcatheter edge-to-edge repair (T-TEER) with the TriClip (Abbott) implant from the TRILUMINATE (TRILUMINATE Study With Abbott Transcatheter Clip Repair System in Patients With Moderate or Greater TR) study for the treatment of severe symptomatic TR.

Methods: The TRILUMINATE study (N = 98 subjects) is an international, prospective, single-arm, multicenter study to investigate the safety and performance of T-TEER with the TriClip implant in patients with symptomatic moderate or greater TR.

Intravenous iron supplementation in pulmonary hypertension groups 1 to 4.

Iron deficiency (ID) is common in patients with pulmonary arterial hypertension and has been associated with increased morbidity and mortality. We aimed to evaluate the therapeutic effects of iron supplementation in iron deficient patients with group 1 to 4 pulmonary hypertension (PH). A total of 85 PH patients (mean age 69.

Regional desynchronization of microglial activity is associated with cognitive decline in Alzheimer's disease.

Background: Microglial activation is one hallmark of Alzheimer disease (AD) neuropathology but the impact of the regional interplay of microglia cells in the brain is poorly understood. We hypothesized that microglial activation is regionally synchronized in the healthy brain but experiences regional desynchronization with ongoing neurodegenerative disease. We addressed the existence of a microglia connectome and investigated microglial desynchronization as an AD biomarker.

Sex differences in physiological correlates of affectively driven decision-making behavior in adult ADHD.

Background: Sex differences in the symptomatology of adults with attention-deficit/hyperactivity disorder (ADHD) have often been overlooked when studying behavioral abnormalities. However, it is known that women exhibit considerably more stronger symptoms related to emotional competence than men. Since affective functions significantly influence the processing of risky decision-making and risk-engagement, we assume that risky behavior in ADHD is affected by sex differences.
