Plants in space face unique challenges, including chronic ionizing radiation and reduced gravity, which affect their growth and functionality. Understanding these impacts is essential to determine the cultivation conditions and protective shielding needs in future space greenhouses. While certain doses of ionizing radiation may enhance crop yield and quality, providing "functional food" rich in bioactive compounds, to support astronaut health, the combined effects of radiation and reduced gravity are still unclear, with potential additive, synergistic, or antagonistic interactions.

Antimicrobial Activity and Mode of Action of N-Heterocyclic Carbene Silver(I) Complexes.

Molecules

December 2024

Department of Pharmacy and Interuniversity Research Centre on Bioactive Peptides (CIRPeB), University of Naples "Federico II", Via Montesano 49, 80131 Naples, Italy.

Silver drugs have played a vital role in human healthcare for the treatment of infections for many centuries. Currently, due to antibiotic resistance, a potential scenario or the application of silver complexes may arise as substitutes for conventional antibiotics. In this perspective, N-heterocyclic carbene (NHC) ligands have been selected as carrier molecules for silver ions.

Non-dioxin-like polychlorinated biphenyls (NDL-PCBs), as well as dioxin-like PCBs, are endocrine disruptors that persist in human and animal tissues worldwide. Due to their lipophilicity and resistance to enzymatic degradation, PCBs accumulate in fat deposits contributing to the onset of endocrine and metabolic diseases. Aquaporins (AQPs) are transmembrane channel proteins that allow the transport of water and small solutes.

Breast cancer, a leading cause of cancer-related mortality in women, is characterized by genomic instability and aberrant gene expression, often influenced by noncanonical nucleic acid structures such as G-quadruplexes (G4s). These structures, commonly found in the promoter regions and 5'-untranslated RNA sequences of several oncogenes, play crucial roles in regulating transcription and translation. Stabilizing these G4 structures offers a promising therapeutic strategy for targeting key oncogenic pathways.

Background: Newborn screening (NBS) is a simple, non-invasive test that allows for the early identification of genetic diseases within the first days of a newborn's life. The aim of NBS is to detect potentially fatal or disabling conditions in newborns as early as possible, before the onset of disease symptoms. Early diagnosis enables timely treatments and improves the quality of life for affected patients.

Cys44 of SARS-CoV-2 3CL affects its catalytic activity.

Int J Biol Macromol

January 2025

Department of Chemical Sciences, University of Naples "Federico II", Via Cintia, 21, 80126 Napoli, Italy; CEINGE Advanced Biotechnologies s.c.a r.l. "Franco Salvatore", Via Gaetano Salvatore 486, 80131 Napoli, Italy. Electronic address:

SARS-CoV-2 encodes a 3C-like protease (3CL) that is essential for viral replication. This cysteine protease cleaves viral polyproteins to release functional nonstructural proteins, making it a prime target for antiviral drug development. We investigated the inhibitory effects of halicin, a known c-Jun N-terminal kinase inhibitor, on 3CL.

Cystic and alveolar echinococcosis are severe zoonotic diseases characterized by long asymptomatic periods lasting months or years. Viable Echinococcus spp. eggs released into the environment through the feces of canids can infect humans through accidental ingestion via hand-to-mouth contact or consumption of contaminated food or water.

Acidogenic fermentation of Ulva in a fed-batch reactor system: tubular versus foliose biomass.

Enzyme Microb Technol

December 2024

University of Galway, University Road, Galway H91 TK33, Ireland; Science Foundation Ireland MaREI Centre for Energy, Climate and Marine, Environmental Research Institute, University College Cork, Cork, Ireland.

The present study proposes a biorefinery of the macroalgae Ulva, focusing on evaluating two different morphologies of the species (foliose and tubular) during acidogenic fermentation in fed-batch reactors. Stage 1 of the study evaluates lyophilised foliose and tubular Ulva, whilst Stage 2 analyses the impact of ulvan extraction on volatile fatty acids yield and changes in carbohydrate availability. Acetic, propionic, and butyric acids were produced from each substrate, with peak concentrations of total VFAs recorded at 2179.

"INSERT-COIN": A PROSPECTIVE STUDY OF COIN INGESTION IN CHILDREN OF SOUTHERN ITALY.

Am J Gastroenterol

December 2024

Pediatric Clinic, Department of Surgical and Biomedical Sciences, University of Perugia, 06123 Perugia, Italy.

Background And Aims: Coins are the most commonly ingested foreign bodies. When they get stuck in the distal esophagus there is no general agreement about the timing of their removal, since some of them may spontaneously migrate into the stomach, no longer requiring removal. We aimed at evaluating the gastric spontaneous passage of esophageal-retained coins, as well as complications.

Anaemia is a frequent consequence of many gastrointestinal (GI) diseases in children and it can even be the initial presenting symptom of underlying chronic GI disease. The definition of anaemia is age and gender-dependent and it can be classified based on pathophysiology, red cell morphology, and clinical presentation. Although nutritional deficiencies, including GI malabsorption of nutrients and GI bleeding, play a major role, other pathophysiologic mechanisms seen in chronic GI diseases, whether inflammatory (e.

Objective: It remains unclear whether baseline FENO levels can predict response to anti-IL5/5R biologic treatment in patients with severe asthma.

Methods: We recruited 104 patients with severe eosinophilic asthma treated with anti-IL5/anti-IL5R for at least one year who had measured FeNO values before the beginning of anti-eosinophilic treatment. Population was divided into subjects with FeNO < 25 and ≥25 ppb.

Extracellular vesicle (EV) monitoring can complement clinical assessment of cancer response. In this study, patients with advanced non-small cell lung cancer (NSCLC) undergoing osimertinib, alectinib, pembrolizumab or platinum-based chemotherapy ± pembrolizumab were enrolled. EVs were characterized using Bradford assay to quantify the circulating cell-free EV protein content (cfEV), and dynamic light scattering to assess Rayleigh ratio excess at 90°, z-averaged hydrodynamic diameter and polydispersity index.

Laboratory of Food Chemistry and Toxicology, Department of Preventive Medicine and Public Health, Food Science, Toxicology and Forensic Medicine, Faculty of Pharmacy, University of Valencia, Avda. Vicent Andrés Estellés, s/n, 46100 Burjassot, Spain.

Mycotoxins pose significant health risks due to their prevalence in food products and severe health implications, including carcinogenicity. This study investigates the bioavailability of mycotoxins aflatoxin B1 (AFB1), ochratoxin A (OTA), and zearalenone (ZEN) individually and combined, in the presence of identified polyphenols from tiger nut beverage (TNB) and tiger nut by-product (TNBP) using the in vitro model Caco-2 cells, which simulates the human intestinal barrier. The objective is to understand how bioactive compounds from TNBP can mitigate the effects of AFB1, OTA and ZEN (and their combination) by bioavailability interference, contributing to safer food products and innovative food safety strategies.

Aims: Secondary mitral regurgitation (SMR) and tricuspid regurgitation (TR) are the most common valvular heart diseases in patients with heart failure (HF). Transcatheter edge-to-edge repair (TEER) devices designed for treating MR and TR have been successfully tested in randomized controlled trials, but methodological issues have often challenged their interpretation. This manuscript aimed to provide an overview of TEER registries on SMR and TR in HF, highlighting their key features, describing clinical characteristics and outcomes of patients receiving these devices, and exploring the available data limitations.
