The Global Plastics Treaty presents an opportunity to “end plastic pollution”. Legacy plastics will continue to fragment to secondary microplastics for decades, without additional mitigation measures. We identify this flux as a “fragmentation gap”, currently overlooked in global policy targets.

Within coating formulations, microcapsules serve as vehicles for delivering compounds like catalysts and self-healing agents. Designing microcapsules with precise mechanical characteristics is crucial to ensure their contents' timely release and minimize residual shell fragments, thereby avoiding adverse impacts on the coating quality. With these constraints in mind, we explored the use of 1 cSt PDMS oil as a diluent (porogen) in trimethylolpropane trimethacrylate (TMPTMA)-based to fabricate microcapsules with customized mechanical properties and submicrometer debris size after shell breakup that can encapsulate a wide range of compounds.

When using navigation devices the "cognitive map" created in the user's mind is much more fragmented, incomplete and inaccurate, compared to the mental model of space created when reading a conventional printed map. As users become more dependent on digital devices that reduce orientation skills, there is an urgent need to develop more efficient navigation systems that promote orientation skills. This paper proposes to consider brain processes for creating more efficient maps that use a network of optimally located cardinal lines and landmarks organized to support and stabilize the neurocognitive structures in the brain that promote spatial orientation.

Objective: We investigated diagnostic utility of phosphorylated tau 217 and 181 (ptau217, ptau181), glial fibrillary acidic protein (GFAP), amyloid beta 42 and 40 (Aβ42, Aβ40), and neurofilament light (NfL) to distinguish biomarker-defined Alzheimer disease (AD) from non-AD conditions, in a heterogenous clinical cohort of younger people.
Methods: Plasma biomarkers were analysed using ultrasensitive technology, and compared in patients with CSF Alzheimer disease profiles (A+T+) to other CSF profiles (Other).
Results: Seventy-nine patients were included, median age 60.

BACKGROUND Shiga toxin-producing Escherichia coli (STEC) causes serious bacterial illnesses from consuming undercooked meat and foods contaminated with feces. This study aimed to describe the characteristics of an STEC outbreak associated with hemolytic uremic syndrome (HUS) that emerged in Turkey and affected 21 adults. MATERIAL AND METHODS The medical records of 21 adult patients who were admitted to Ankara Bilkent City Hospital Internal Medicine Intensive Care Department with the diagnosis of HUS between July and September 2022 were retrospectively evaluated through the system.
