Background: Despite the use of Next-Generation Sequencing (NGS) as the gold standard for the diagnosis of rare diseases, its clinical implementation has been challenging, limiting the cost-effectiveness of NGS and the understanding, control and safety essential for decision-making in clinical applications. Here, we describe a personalized NGS-based strategy integrating precision medicine into a public healthcare system and its implementation in the routine diagnosis process during a five-year pilot program.

Methods: Our approach involved customized probe designs, the generation of virtual panels and the development of a personalized medicine module (PMM) for variant prioritization.

Histones are essential nuclear proteins that package eukaryotic DNA into chromosomes, play a vital role in gene regulation, DNA replication, DNA repair and chromosome condensation. Understanding histone modifications is crucial for grasping biological and disease-related processes. Specific alterations in histone modifications serve as sensitive and selective biomarkers for conditions like cancer, impacting both tumor and immune cells and affecting their interactions.

Nutrient acquisition is crucial for sustaining life. Plants develop beneficial intracellular partnerships with arbuscular mycorrhiza (AM) and nitrogen-fixing bacteria to surmount the scarcity of soil nutrients and tap into atmospheric dinitrogen, respectively. Initiation of these root endosymbioses requires symbiont-induced oscillations in nuclear calcium (Ca) concentrations in root cells.

iScience

January 2025

Section of Cell Biology and Functional Genomics, Department of Medicine, Endocrinology and Metabolism, Imperial College London, London, UK.

Long non-coding RNAs (lncRNAs) are emerging as crucial regulators of beta cell function. Here, we show that an lncRNA-transcribed antisense to Pax6, annotated as Pax6os1/PAX6-AS1, was upregulated by high glucose concentrations in human as well as murine beta cell lines and islets. Elevated expression was also observed in islets from mice on a high-fat diet and patients with type 2 diabetes.

Exploring the synergistic effect of NaOH/NaClO absorbent in a novel wet FGD scrubber to control SOx/NOx emissions.

Environ Monit Assess

January 2025

International Joint Research Center For Green Energy and Chemical Industry, School of Chemical Engineering, East China University of Science and Technology, Shanghai, 200237, People's Republic of China.

Escalating SOx and NOx emissions from industrial plants necessitates customized scrubbing solutions to improve removal efficiency and tackle cost limitations in existing wet FGD units. This work investigates the real-time intensified removal pathways via an innovative two-stage countercurrent spray tower configuration strategically integrating NaOH (M) and NaOH/NaClO (M/M) to remove SOx and NOx emissions simultaneously from the industrial stack through a comprehensive parametric study of absorbents concentration, reaction temperature, gas flow rate, liquid to gas ratio (F/F), and absorbent showering head. Flue gas stream comprising SO bearing 4500 ppm, SO bearing 300 ppm, 70 ppm NO, and 50 ppm NO brought into contact with two scrubbing solutions as M, and a complex absorbent of M/M at varying respective ratios.

Persistent elite controllers as the key model to identify permanent HIV remission.

Curr Opin HIV AIDS

December 2024

Institute of Biomedicine of Seville (IBiS), Virgen del Rocio University Hospital, Spanish National Research Council (CSIC), University of Seville, Clinical Unit of Infectious Diseases, Microbiology and Parasitology, Seville, Spain.

Purpose Of Review: To summarize the heterogeneity in the elite controllers population with the aim to identify a compatible profile with a persistent HIV remission, making distinction between persistent elite controllers, people with HIV (PWHIV) who permanently maintain virological control in the absence of antiretroviral treatment (ART), and transient elite controllers, PWHIV who eventually lose virological control. For this purpose, it is important to consider the mechanisms and biomarkers that have previously been associated with the maintenance and loss of the natural virological control.

Recent Findings: Transient elite controllers, before losing virological control, exhibit a distinct metabolomic, proteomic, microRNAs (miRNA), immunological and virological profile compared to persistent elite controllers.
