Significant investment in nanocarrier drug delivery systems (Nano-DDSs) has yielded only a limited number of successfully marketed nanomedicines, highlighting a low rate of clinical translation. A primary contributing factor is the lack of foundational understanding of processes. Comprehensive knowledge of the pharmacokinetics of Nano-DDSs is essential for developing more efficacious nanomedicines and accurately evaluating their safety and associated risks.

In recent years, solar-driven photothermal water evaporation technology for seawater desalination and wastewater treatment has developed rapidly, which is of great significance for addressing the issue of freshwater scarcity. However, due to the high costs associated with the manufacturing, maintenance, and operation of such devices, their application remains challenging in remote and resource-scarce regions. Due to its excellent light absorption capability in the near-infrared region, high hydrophilicity, and stable chemical properties, coupled with the low cost of recycling waste carbonized polyphenylene sulfide, this material is an excellent choice as a photothermal material for solar-driven water evaporation devices.

Developing smart materials with tunable high-temperature afterglow (HTA) luminescence remains a formidable challenge. This study presents a metal-free doping system using boric acid as matrix and polycyclic aromatic hydrocarbons as dopants. This composition achieves dynamically tunable afterglow combining a bright blue HTA lasting for over ten seconds even at 150 °C and an ultra-long yellow room-temperature phosphorescence below 110 °C.

Article Synopsis
  • Deoxynivalenol (DON) is a harmful mycotoxin produced by Fusarium species, commonly found in wheat and grains, and has been a focus for enzymatic degradation studies.
  • The study identifies a dehydrogenase enzyme (Pe DDH) from Pelagibacterium sp. SCN 63-126 that effectively breaks down DON, demonstrating optimal activity at 35°C and pH 8.5.
  • Pe DDH's activity is significantly enhanced by the presence of calcium, magnesium, copper, and certain chemical cofactors, allowing it to degrade DON quickly, highlighting its potential for reducing DON contamination in grains.*

Article Synopsis
  • - Deoxynivalenol (DON) is a harmful mycotoxin produced by Fusarium fungi, commonly contaminating grains like wheat, which poses risks to health and agriculture; enzymatic treatments have emerged as effective methods to control its levels.
  • - A new enzyme called DON dehydrogenase (DeDDH) from Devosia yakushimensis was found to be most active at 35°C and pH 7.5, with good stability at higher temperatures and the ability to degrade 75% of DON within 4 hours, further enhanced by specific cofactors.
  • - Key residues in the enzyme's structure were identified as crucial for its activity, but more research is necessary to understand its structure and

Recently, water resources have become scarce due to the growing global population and human impact on the environment, coupled with the effects of climate change. For solving the problem of global freshwater shortage and increasing the value of discarded polyphenylene sulfide (PPS) filter bags, in this study, balsa wood was used as the base of a photothermal solar evaporator, chitosan solution was used as the binder, and the main photothermal conversion materials used were polyphenylene sulfide (CP) carbide and copper sulfide. In order to create synergistic photothermal conversion materials, freeze-drying and precipitation were used to deposit the photothermal conversion materials on top of the balsa wood.

Harsh environments in poorly perfused tumor regions may select for traits driving cancer aggressiveness. Here, we investigated whether tumor acidosis interacts with driver mutations to exacerbate cancer hallmarks. We adapted mouse organoids from normal pancreatic duct (mN10) and early pancreatic cancer (mP4, KRAS-G12D mutation, ± p53 knockout) from extracellular pH 7.

Background: Ice and snow sports, which are inherently high risk due to their physically demanding nature, pose significant challenges in terms of participant safety. These activities increase the likelihood of injuries, largely due to reduced bodily agility and responsiveness in cold, often unpredictable winter environments. The critical need for effective injury prevention in these sports is emphasized by the considerable impact injuries have on the health of participants, alongside the economic and social costs associated with medical and rehabilitative care.

Parkinson's disease (PD) represents the second most widespread neurodegenerative disease, and early monitoring and diagnosis are urgent at present. Tyrosine hydroxylase (TH) is a key enzyme for producing dopamine, the levels of which can serve as an indicator for assessing the severity and progression of PD. This renders the specific detection and visualization of TH a strategically vital way to meet the above demands.

The magnetic skyrmions exhibit intriguing topological behaviors, holding promise for future applications in the realm of spintronic devices. Despite recent advancements, achieving spontaneous magnetic skyrmions and topological transitions in magnets featuring uniaxial magnetic anisotropy, particularly at elevated temperatures (>100 K), remains a challenging endeavor. Here, single-crystal FeSi nanorods with the central symmetry and uniaxial magnetic anisotropy were successfully synthesized on a mica substrate through chemical vapor deposition, which exhibit a high Curie temperature () of about 372 K.

Although many studies have investigated attentional biases toward weight-related information among individuals with weight dissatisfaction, the mechanisms underlying the processing of task-irrelevant and spatial-irrelevant weight-related information as distractors remain unclear. Participants were assigned to groups according to their levels of weight dissatisfaction to address this question. Participants with high weight dissatisfaction (HWD) were assigned to the experimental group; those with low weight dissatisfaction (LWD) were assigned to a control group.

Although there is substantial evidence of visual attentional biases in processing weight-related information among individuals with weight dissatisfaction, few studies have examined auditory attentional biases in these individuals. The identification of attentional biases may provide an impetus for interventions to reduce distress, negative body image, and pathological eating patterns among weight-dissatisfied individuals. Therefore, the present study aimed to investigate the attentional biases, as well as the neural consequences, toward auditory weight-related information among weight-dissatisfied young females.

The mechanisms linking tumor microenvironment acidosis to disease progression are not understood. Here, we used mammary, pancreatic, and colon cancer cells to show that adaptation to growth at an extracellular pH (pH ) mimicking acidic tumor niches is associated with upregulated net acid extrusion capacity and elevated intracellular pH at physiological pH , but not at acidic pH . Using metabolic profiling, shotgun lipidomics, imaging and biochemical analyses, we show that the acid adaptation-induced phenotype is characterized by a shift toward oxidative metabolism, increased lipid droplet-, triacylglycerol-, peroxisome content and mitochondrial hyperfusion.
