PSMA-targeted delivery of docetaxel in prostate cancer using small-sized PDA-based micellar nanovectors.

J Control Release

January 2025

Asymmetric Synthesis and Functional Nanosystems Group (Art&Fun), Institute of Chemical Research (IIQ), CSIC-University of Seville, C/ Américo Vespucio 49, 41092 Seville, Spain. Electronic address:

In this study, we present the first comparative analysis of active and passive drug delivery systems for docetaxel (DTX) in prostate cancer using supramolecular self-assembled micellar nanovectors. Specifically, we developed two novel micelles based on polydiacetylenic amphiphiles (PDA) for passive and active targeting. The active targeting micelles were designed with a prostate-specific membrane antigen (PSMA) ligand, ACUPA, to facilitate recognition by PSMA-positive cancer cells.

The ubiquitin proteasome system (UPS) is implicated in protein homeostasis. One of the proteins involved in this system is HERC1 E3 ubiquitin ligase, which was associated with several processes including the normal development and neurotransmission at the neuromuscular junction (NMJ), autophagy in projection neurons, myelination of the peripheral nervous system, among others. The tambaleante (tbl) mouse model carries the spontaneous mutation Gly483Glu substitution in the HERC1 E3 protein.

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.

Department of Medical Biochemistry and Molecular Biology and Immunology, Medical School, Virgen Macarena University Hospital, University of Seville, Seville, Spain; Cancer Division, Faculty of medicine, Imperial college London, United Kingdom.

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.

Eur Heart J

January 2025

Department of Primary Care and Public Health, Imperial Centre for Cardiovascular Disease Prevention, School of Public Health, Imperial College London, White City Campus, 90 Wood Lane, London W12 0BZ, UK.

Background And Aims: Overweight and obesity are modifiable risk factors for atherosclerotic cardiovascular disease (ASCVD) in the general population, but their prevalence in individuals with heterozygous familial hypercholesterolaemia (HeFH) and whether they confer additional risk of ASCVD independent of LDL cholesterol (LDL-C) remains unclear.

Methods: Cross-sectional analysis was conducted in 35 540 patients with HeFH across 50 countries, in the EAS FH Studies Collaboration registry. Prevalence of World Health Organization-defined body mass index categories was investigated in adults (n = 29 265) and children/adolescents (n = 6275); and their association with prevalent ASCVD.
