Premastication-Review of an Infant Feeding Practice and Its Potential Impact on Allergy and Microbiome Development.

Premastication, or pre-chewing, of food as a feeding practice for infants has been practiced across cultures as an ancient evolutionary method. Whilst literature on the topic remains slim, the majority of existing research has highlighted the potential risks, such as transmission of infections. Although the concerns are valid, potential beneficial aspects have, until now, received less attention.

Leukocytes use endothelial membrane tunnels to extravasate the vasculature.

Upon inflammation, leukocytes extravasate through endothelial cells. When they extravasate, it is generally accepted that neighboring endothelial cells disconnect. Careful examination of endothelial junctions showed a partial membrane overlap beyond VE-cadherin distribution.

Molecularly matched targeted therapies plus radiotherapy in glioblastoma: the phase 1/2a NM umbrella trial.

Advances in molecular understanding and diagnostic precision of glioblastoma enable the identification of key genetic alterations in a timely manner and, in principle, allow treatments with targeted compounds based on molecular markers. Here we report the results of the phase 1/2 umbrella trial NCT Neuro Master Match (NM), which evaluated targeted treatments in 228 patients with newly diagnosed glioblastoma without O6-methylguanine DNA-methyltransferase promoter hypermethylation. Stratification for treatment was conducted by a trial-specific molecular tumor board across five subtrials, each evaluating a targeted therapy-alectinib, idasanutlin, palbociclib, vismodegib or temsirolimus-selected according to the best-matching molecular alteration.

Machine learning in NMR spectroscopy.

NMR spectroscopy is a versatile technique for studies of molecular structures, dynamic processes, and intermolecular interactions across a broad range of systems, including small molecules, macromolecules, biomolecular assemblies, and materials in both solution and solid-state environments. As the complexity of NMR studies continues to pose challenges for practitioners, the integration of machine learning is recognized as a promising research direction for improving data acquisition, processing, and analysis. Here, we summarize recent findings in this area, highlighting common applications such as signal detection, chemical shift assignment, structure determination, chemical shift prediction, non-uniform sampling reconstruction, and denoising.

Outcome of systemic therapy in patients with advanced rare skin cancers: A retrospective multicenter DeCOG study of 209 patients.

Introduction: For rare skin cancers, few data exist on the outcome of systemic therapies, particularly immune checkpoint inhibition (ICI). The present study analysed the real-world use of different systemic therapies including ICI, and its outcome in patients with advanced rare skin cancers.

Methods: This retrospective multicenter study included patients who received systemic therapy for advanced, non-resectable cutaneous angiosarcoma (AS), Kaposi sarcoma (KS), pleomorphic dermal sarcoma (PDS), or cutaneous adnexal carcinoma (CAC).

Impact of bleeding and thrombosis on outcome of 945 COVID-19 VV-ECMO cases from a German registry.

Unlabelled: Bleeding and thromboembolic events (BTE) increase the mortality of COVID-19 acute respiratory distress syndrome (ARDS) treated with extracorporeal membrane oxygenation (ECMO). The current analysis aimed to assess frequency and determinants of BTE according to their location and severity in a retrospective analysis of the German ECMO COVID-19 registry. Logistic regression was applied to identify factors influencing ICU survival as well as variables associated with risks of BTE.

Native T1 adds independent value for cardiovascular risk assessment beyond global longitudinal strain in an all-comers real-world clinical patient population.

Methods: This retrospective 1:3 single center case-control study analyzed patient data from 2004 to 2023.

Impacts of climate change on the dilution capacity of perennial and non-perennial European rivers.

Rivers provide ecosystem services, such as water purification and drinking water supply, which depend on the river's capacity to dilute effluents from wastewater treatment plants (WWTPs). There are no large-scale analyses of the dilution capacity of rivers that take into account the differences between perennial and non-perennial river reaches, even though more than half of the world's river and stream reaches are estimated to be non-perennial. We evaluated the actual and future capacity of perennial and non-perennial river reaches in Europe to dilute WWTP effluents.

Behavioral investigation of reactive and neoplastic lymphocytes in human lymph nodes in 4D.

This study deals with a 4D investigation of lymphocytes in human tissue under reactive and neoplastic conditions. The immune system's response to pathogens highly depends on cell interaction and movement, which makes it essential to analyze these dynamics. To achieve this, we observed cells and their movement in 4D.

Selectivity profiles and substrate recognition of Rab-phosphorylating kinases.

The Rab GTPase switch-2 region is a hotspot for post-translational modifications. Its phosphorylation can determine whether individuals develop Parkinson's disease or not. Other modifications of the same region are catalyzed by enzymes from bacterial pathogens when they infect human cells.

Breaking primary checkpoint inhibitor resistance with intermittent alkylating chemotherapy in patients with metastatic melanoma - Results of a multicenter phase II study.

Background: Patients with BRAF wild type (wt) metastatic melanoma who exhibit primary resistance to immune checkpoint inhibitors (ICI) face a poor prognosis. Chemotherapy has been shown to induce genetic mutations, modify the tumor microenvironment and microbiome, and influence immune system activity.

Objectives: This prospective multicenter phase II trial investigates whether two applications of an alkylating agent (dacarbazine/DTIC) can sensitize ICI non-responsive patients with metastatic melanoma to the same checkpoint inhibitor regime.

Differences between persistent and episodic depression in processing novel positive information.

Background: Research has pointed to important psychopathological differences between persistent and episodic depressive disorders. Here, we tested the hypothesis that people with persistent rather than episodic depression have difficulty revising established expectations in response to novel positive information. In terms of underlying mechanisms, we predicted that these differences between the two subtypes would be related to the engagement in cognitive immunization (i.

Frequency and patterns of CMF emergency cases during and after COVID-19.

Background: Craniomaxillofacial (CMF) trauma constitutes a significant proportion of hospital presentations, often resulting from high-energy mechanisms such as interpersonal violence and traffic accidents. The COVID-19 pandemic and associated public health restrictions markedly altered daily life and social behavior, potentially influencing trauma patterns and emergency healthcare utilization.

Methods: We conducted a retrospective analysis of nationwide anonymized inpatient data from German hospitals, reported to the National Institute for the Hospital Remuneration System (InEK), covering the period from March 18, 2019 to March 17, 2023.

Statistical learning and representational drift: A dynamic substrate for memories.

In many brain areas, neurons exhibit continuous changes in their tuning properties over days, even when supporting stable percepts and behaviors-a phenomenon termed representational drift. How do neuronal circuits maintain stable function when their constituent elements are in constant flux? Here, we review recent theoretical and experimental work on interconnected levels, ranging from perpetual changes in synapses driving drifts in tuning of individual neurons to emergent stability at the population level, preserving similarities of activity patterns associated to specific percepts or behaviors. We propose that statistical learning, beyond its well-established roles during development and adaptation to new contexts, is also essential under steady behavioral and environmental conditions to safeguard the stability of representational similarities.

Structural basis for ligand recognition in the tobramycin riboswitch.

Recently, a novel tobramycin-responsive riboswitch was developed by a combination of Capture-SELEX and in vivo screening. This riboswitch regulates translation initiation in eukaryotes with a high dynamic range and remarkable ligand affinity and selectivity. Its secondary structure differs from all previously described aminoglycoside-binding RNA motifs, suggesting a novel mode of ligand recognition.
