BACKGROUND: Non-communicable diseases (NCDs) account for over 60% of annual global deaths, disproportionately affecting low- and middle-income countries. This trend undermines progress toward Sustainable Development Goal (SDG) 3.4, which seeks to reduce premature mortality from NCDs by one-third by 2030. Despite the availability of effective and relatively affordable interventions, addressing NCDs requires sustained, coordinated efforts and robust monitoring systems. Facility-based monitoring...

In microbial communities, viruses compete for host cells and have evolved diverse mechanisms to inhibit competitors. One strategy is superinfection exclusion, whereby an established viral infection prevents a secondary infection of the same cell¹. This phenomenon has been shown to have an important role in the spread of eukaryotic viruses. Here we determine that superinfection exclusion proteins in bacterial viruses (bacteriophages, hereafter phages) perform a similar role, promoting viral...

CONCLUSIONS: The MAP-OUTCOMES model demonstrated the feasibility of using ML to predict survival-based outcomes from waterfall plots, thus providing a potential tool for early trial evaluation. Improving the model's performance with more training data and creating independent datasets are necessary steps to assess its generalizability for prospective clinical applications.

Omega n-3 polyunsaturated fatty acid (n-3 PUFA) intake is associated with reduced inflammation, protection against cardiovascular disease, and improved cognitive function. There is also evidence that n-3 PUFA intake impacts skeletal muscle, potentially with greater effects in females than males. Sex-specific responses to n-3 PUFA intake may be linked to the incorporation of eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) into skeletal muscle phospholipid membranes....

Municipal and industrial wastewater, along with organic waste, can be transformed into valuable bioproducts using purple phototrophic bacteria. This study compares the performance of three machine learning models (Random Forest, XGBoost, and CatBoost) in predicting and optimizing the formation of key bioproducts: polyhydroxybutyrate, polyhydroxyvalerate, 5-aminolevulinic acid, coenzyme Q10, carotenoids, bacteriochlorophylls, and biomass. The models were trained on a dataset compiled from...

The potential for bioremediation of dichloroanilines (2,3- and 3,4-DCA) and dichloronitrobenzenes (3,4-, 2,5-, and 2,3-DCNB) was investigated using inocula from an industrial site in the northeast of Brazil. Anaerobic biotransformation of these chlorinated compounds was observed in microcosms simulating site conditions, particularly when an electron donor was added. To disentangle specific transformation reactions, subcultures from active anaerobic microcosms were enriched with individual DCA or...

2,3-dichloroaniline (2,3-DCA) has widespread use in chemical manufacturing and remains a persistent groundwater contaminant. To better understand the pathway and kinetics of its reductive dechlorination, we conducted a laboratory kinetic experiment using an anaerobic enrichment culture dominated by Dehalobacter. At an initial field-relevant concentration of 40 mg/L, complete and stoichiometric dechlorination of 2,3-DCA to aniline via 2-chloroaniline (2-CA) was achieved. The intermediates, 2-CA...

BACKGROUND: IDH-mutant diffuse gliomas are considered low grade, albeit with a propensity for malignant behavior over time, distinguishing them from pediatric-type low-grade gliomas. IDH-mutant tumors have astrocytic or oligodendrocytic phenotypes associated with TP53 and ATRX mutations or 1p/19q deletions, respectively. TP53 mutations are associated with a tumor that acquires malignant properties characteristic of glioblastoma with subsequent very poor survival.

ADP-heptose (ADP-Hep), a metabolite produced by gram-negative bacteria, is detected in the host cytosol by the kinase ALPK1, which engages TIFA-dependent innate immune responses. However, the function of ALPK1-TIFA signaling in primary cells and in physiological settings remains poorly understood. Here, we showed that, in the intestinal epithelium, ALPK1 and TIFA were mainly expressed by the intestinal stem cell (ISC) pool, where they controlled the replacement of homeostatic ISCs by new revival...

Background/Objectives: An accurate evaluation of variant actionability is essential in cancer management. In Von Hippel-Lindau Syndrome (VHL), the interpretation of the germline variants is confounded by the presence of non-syndromic component tumors, such as clear cell renal cell carcinoma (ccRCC), hemangioblastoma, pheochromocytoma, and neuroendocrine tumors. These tumors frequently occur sporadically, without any association with VHL syndrome. The presence of these tumors in a patient with a...

The controlled migration of ions in biological systems has inspired the development of ion-based electronics. Ionic diodes, leveraging ions as charge carriers, offer selective control over ion flux, mimicking ion-selective behavior observed in biological systems. Conventional ionic diodes containing fluids encounter challenges in adapting to biological systems due to their limited stretchability and stability. Recent advancements in solid-state ionic diodes based on stretchable gels enable...

In this 5th version of the European LeukemiaNet guidance for adult patients, there are important changes in several areas of management based on evidence available since 2020, including the World Health Organisation's reclassification of CML as a biphasic disease. Previous advice to switch the tyrosine kinase inhibitor (TKI) on failure of molecular milestones, is modified to better account for individual patient circumstances. Our recommendations are summarized in tables designed to be read in...

Proximity-dependent biotinylation (BioID) is a powerful means of exploring the cellular environments in which proteins reside. Expressing a protein of interest (bait) fused to a biotin ligase and adding biotin induces the covalent biotinylation of proximal partners (preys), which are recovered on streptavidin beads and identified by MS. However, a major technical limitation of BioID is peptide carryover into subsequent MS runs. This is typically mitigated via lengthy intersample wash cycles,...

Many phages encode recombination-mediating enzymes, but characterization of their roles in phage lifecycles is limited, and their impact on phage replication is controversial. To address these issues, we have searched for phages whose growth is impacted by the major recombination-promoting helicase-nuclease of Escherichia coli, the RecBCD enzyme. Although no phages inhibited by RecBCD are identified, growth of a newly isolated phage, named LLS, is enhanced by RecBCD. LLS's genome sequence...

Genetic variants often produce complex phenotypic effects that confound current assays and predictive models. We developed Variant in situ sequencing (VIS-seq), a pooled, image-based method that measures variant effects on molecular and cellular phenotypes in diverse cell types. Applying VIS-seq to ~3,000 LMNA and PTEN variants yielded high-dimensional morphological profiles that captured variant-driven changes in protein abundance, localization, activity and cell architecture. We identified...

The subgenual anterior cingulate cortex (sgACC) plays a central role in the pathophysiology of major depressive disorder (MDD). Its functional interactive profile with the left dorsal lateral prefrontal cortex (DLPFC) is associated with transcranial magnetic stimulation (TMS) treatment outcomes. Previous research on sgACC functional connectivity (FC) in MDD has yielded inconsistent results, partly due to small sample sizes and limited statistical power. Furthermore, calculating sgACC-FC to...

CONCLUSION: Preoperative zonulin levels were lowest in the TCA group. The change in zonulin levels on the first day after surgery can serve as a useful indicator for predicting the risk of postoperative HAEC occurrence.
