With over 14 million people living above 3,500 m, the study of acclimatization and adaptation to high altitude in human populations is of increasing importance, where exposure to high altitude (HA) imposes a blood oxygenation and acid-base challenge. A sustained and augmented hypoxic ventilatory response protects oxygenation through ventilatory acclimatization, but elicits hypocapnia and respiratory alkalosis. A subsequent renally mediated compensatory metabolic acidosis corrects pH toward baseline values, with a high degree of interindividual variability.

Patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) have poor outcomes. Gemcitabine + oxaliplatin (GemOx) with rituximab, a standard salvage therapy, yields complete response (CR) rates of approximately 30% and median overall survival (OS) of 10-13 months. Patients with refractory disease fare worse, with a CR rate of 7% for subsequent therapies and median OS of 6 months.

Triple negative breast cancers often contain higher numbers of tumour-infiltrating lymphocytes compared with other breast cancer subtypes, with their number correlating with prolonged survival. Since little is known about tumour-infiltrating lymphocyte trafficking in triple negative breast cancers, we investigated the relationship between tumour-infiltrating lymphocytes and the vascular compartment to better understand the immune tumour microenvironment in this aggressive cancer type. We aimed to identify mechanisms and signaling pathways responsible for immune cell trafficking in triple negative breast cancers, specifically of basal type, that could potentially be manipulated to change such tumours from immune "cold" to "hot" thereby increasing the likelihood of successful immunotherapy in this challenging patient population.

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) results from maternal antibodies targeting fetal platelets during pregnancy, often causing hemorrhagic manifestations detectable antenatally or shortly after birth. We report an atypical form of FNAIT with delayed onset in a healthy, breastfed male infant who developed diffuse petechiae 2 weeks after birth due to severe thrombocytopenia. The mother was shown to be negative for the human platelet antigen-1a (HPA-1a) allele but had anti-HPA-1a IgG antibodies, while the father and newborn were HPA-1a positive, confirming the diagnosis.

Pupil responses are commonly used to provide insight into visual perception, autonomic control, cognition, and various brain disorders. However, making inferences from pupil data can be complicated by nonlinearities in pupil dynamics and variability within and across individuals, which challenge the assumptions of linearity or group-level homogeneity required for common analysis methods. In this study, we evaluated luminance evoked pupil dynamics in young healthy adults (n = 10, M:F = 5:5, ages 19-25 years) by identifying nonlinearities, variability, and conserved relationships across individuals to improve the ability to make inferences from pupil data.

Human recombination-activating gene (RAG) deficiency can manifest with distinct clinical and immunological phenotypes. By applying a multiomics approach to a large group of -mutated patients, we aimed at characterizing the immunopathology associated with each phenotype. Although defective T and B cell development is common to all phenotypes, patients with hypomorphic variants can generate T and B cells with signatures of immune dysregulation and produce autoantibodies to a broad range of self-antigens, including type I interferons.

Unipept, a pioneering software tool in metaproteomics, has significantly advanced the analysis of complex ecosystems by facilitating both taxonomic and functional insights from environmental samples. From the onset, Unipept's capabilities focused on tryptic peptides, utilizing the predictability and consistency of trypsin digestion to efficiently construct a protein reference database. However, the evolving landscape of proteomics and emerging fields like immunopeptidomics necessitate a more versatile approach that extends beyond the analysis of tryptic peptides.

Variations and Opportunities in Postnatal Management of Hemolytic Disease of the Fetus and Newborn.

JAMA Netw Open

January 2025

Division of Neonatology, Department of Pediatrics, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, the Netherlands.

Importance: Preventive efforts in pregnancy-related alloimmunization have considerably decreased the prevalence of hemolytic disease of the fetus and newborn (HDFN). International studies are therefore essential to obtain a deeper understanding of the postnatal management and outcomes of HDFN. Taken together with numerous treatment options, large practice variations among centers may exist.

In motor adaptation, learning is thought to rely on a combination of several processes. Two of these are implicit learning (incidental updating of the movement due to sensory prediction error) and explicit learning (intentional adjustment to reduce target error). The explicit component is thought to be fast adapting, while the implicit one is slow.

Anion Transport by Bambusuril-Bile Acid Conjugates: Drastic Effect of the Cholesterol Content.

Angew Chem Int Ed Engl

January 2025

Universite Libre de Bruxelles, Engineering of Molecular NanoSystems, Avenue F. Roosevelt 50, 1050, Brussels, BELGIUM.

Artificial anion transporters offer a potential way to treat deficiencies in cellular anion transport of genetic origins. In contrast to the large variety of mobile anion carriers and self-assembled anion channels reported, unimolecular anion channels are less investigated. Herein, we present a unique example of a unimolecular anion channel based on a bambusuril (BU) macrocycle, a well-established anion receptor.

Alpha-ketoglutarate-dependent dioxygenase, also known as fat mass and obesity-associated protein (FTO), is an RNA demethylase that mediates the demethylation of N,2-O-dimethyladenosine (m6Am) and N-methyladenosine (m6A). Both m6Am and m6A are prevalent modifications in mRNA and affect different aspects of transcript biology, including splicing, nuclear export, translation efficiency, and degradation. The role of FTO during (herpes) virus infection remains largely unexplored.

There should be no assumption that an athlete is immune to coronary artery disease (CAD), even when traditional cardiovascular (CV) risk factors appear well-managed. Excelling in certain aspects of health does not equate to total CV protection. Recent data from cardiac imaging studies have raised the possibility that long-term, high-volume, high-intensity endurance exercise is associated with coronary atherosclerosis.
