Article Abstract
Water accumulating in the bottom of ships (bilge water), contains a mixture of oil, detergents and other compounds from on board activities. To evaluate ecological effects of released bilge water the chemical composition and toxicity of treated bilge water from seven passenger ships was analysed. The oil content was below 15mgL, the threshold for legal discharge, in all but one ship. Still, significant reductions in feeding and reproduction of Acartia tonsa were found after 48h exposure in dilutions with 2.5-5% of bilge water. Mortality was significant at dilutions of 5-10% in 4 of the 5 bilge water samples. Surfactants were the most significant contributor to the toxicity on copepod vital rates and survival. Toxicity was also tested with Microtox where an EC was found at dilutions between 4.3% and 52%. The results show that ecological effects might occur also in diluted suspensions of bilge water.

Background: Transglutaminase-2 (TG2) plays a key role in age-related vascular stiffness. This study aims to evaluate the effects of calorie restriction (CR) on TG2 mRNA and protein levels and identify differentially expressed microRNAs (miRNA) predicted to target TG2.
Methods And Results: Female mice were assigned to ad libitum (AL), chronic CR (CCR), and intermittent CR (ICR) groups for 80 weeks.
Reinforcing polyvinyl alcohol with corn stover-derived nanofibrillated cellulose for improved mechanical and barrier properties.

The growing demand for sustainable materials has accelerated the development of biodegradable composites, with cellulose-based materials gaining attention for their abundance, renewability, and biodegradability. The study explores the fabrication and characterization of polyvinyl alcohol (PVOH)-based composite films reinforced with nano fibrillated cellulose (NFC) derived from corn stover (CS NFC). Composite films were prepared with varying PVOH: CS NFC ratios (99:1, 97:3, 95:5) and analyzed for their thermal, mechanical, barrier, and structural properties using thermogravimetric analysis (TGA), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and ASTM-standard methods for physical and barrier property measurements.

Marine pollution management requires identifying all sources of contaminants, yet shipping's role in marine contamination remains unexplored. To address this gap, we investigated shipping contribution to water and air pollutant loads in the Northern Adriatic Sea in 2018 and under two future scenarios. The approach integrated (i) modelled data of shipping-related emissions, (ii) load from tributaries, and (iii) land-based emissions to the atmosphere.
