Summary: In this study, TEM and NanoSIMS imaging were used to quantify subvesicular compartments and measure the partial release fraction of C-13-dopamine in cellular nanovesicles. Three modes of exocytosis were examined and it was found that there was no correlation between vesicle size and the fraction of partial release. The presence of isotopic dopamine indicated vesicle content, while an I-127-labelled drug was used to identify vesicles that underwent partial release.

Summary: This study reports an in vivo strategy to construct cell-based nanomedicine carriers using bacteria-mimetic gold nanoparticles, which are selectively phagocytosed by immune cells and self-assemble into intracellular aggregates. The optimized carriers improve drug delivery and enhance antitumor immunotherapy through photothermal treatment and immune checkpoint blockade.

Summary: Melanoma, a highly lethal form of skin cancer, can be treated with targeted nanoparticle drug delivery systems. Nanoparticles functionalized with different ligands are used to deliver drugs specifically to melanoma cells, reducing systemic toxicity. Coating nanoparticles with melanoma or immune cell membranes further enhances drug accumulation at the tumor site and improves therapeutic effects. This review highlights recent advances in targeted nanoparticle drug delivery systems for melanoma therapy.

Summary: High-spatial-resolution secondary ion mass spectrometry is a powerful tool for mapping lithium at nanoscale lateral resolution. Two state-of-the-art methods demonstrate the visualization of nanoscale Li-rich phases in an aluminium-lithium alloy, providing insight into the distribution and size of T-1 (Al2CuLi) precipitates. Correlation with high resolution electron microscopy confirms the identification of T-1 precipitates and their sizes observed during SIMS mapping.

Summary: Reduced eye contact early in life may be a factor in the development of autism spectrum disorder, but there are conflicting theories about the neural mechanisms involved. The amygdala theory suggests that reduced eye contact is due to a hypoactive amygdala that fails to recognize eyes as important. In contrast, the eye avoidance hypothesis proposes that amygdala hyperactivity leads to eye avoidance. A review of studies found that most supported the eye avoidance hypothesis, indicating that individuals on the autism spectrum use eye avoidance to reduce amygdala-related hyperarousal.

Summary: Based on a national survey and series of roundtables, researchers found that community-based prevention and support of traumatic brain injury (TBI) are challenging and underresearched. They identified three key themes: accessible, nationally consistent plain-language guidelines; building research literacy; and knowing your role in TBI identification and management.

Summary: Traumatic intracranial hypertension (tIH) is a common complication of moderate to severe traumatic brain injury (m-sTBI) that can be lethal. The development of technology to predict tIH and administer interventions prior to the rise in intracranial pressure (ICP) has been a focus of research. In 2022, the first operationalizable tIH prediction system was developed, allowing for proactive management and protection of patients from potential harm. This review discusses the approaches to ICP forecasting and tIH prediction algorithms that form the foundation for this operational system, offering valuable insights for clinicians and researchers interested in this technology.

Summary: Bioerosion on inshore reefs is expected to increase with global climate change reducing reef stability and accretionary potential. Most studies investigating bioerosion have focused on external grazers, such as parrotfish and urchins, whose biomass is more easily measured. Yet, cryptic endolithic bioeroders such as macroboring (worms, sponges and bivalves) and microboring taxa (fungus and algae) have the potential to be the dominant source of reef erosion, especially among inshore reef systems exposed to increased nutrient supply.

Summary: This scoping review identified cardiovascular changes in some individuals following mild traumatic brain injury (mTBI), which may be related to disturbances of the autonomic nervous system and cerebral blood flow. The review found evidence of cerebral blood flow impairments and microstructural brain injury that may be responsible for the cardiovascular autonomic changes associated with mTBI. However, due to variability in study methodology and terminology, definitive conclusions cannot be drawn from the available data.

Summary: Optic nerve injury leads to secondary degeneration, which is caused by mechanisms such as oxidative stress, apoptosis, and blood-brain barrier dysfunction. This study investigates the occurrence of oxidative damage in oligodendrocyte precursor cells (OPCs) at different time points post-injury and its relationship with therapeutic intervention for limiting degeneration. The results highlight the early occurrence of oxidative damage and apoptosis in OPCs and emphasize the importance of considering this in therapeutic efforts following optic nerve injury.

Summary: The authors investigated the crystallization pathways involved in the formation of nacre and how they affect the incorporation of trace elements. They found that nacre grows through a two-step process and crystallizes through localised dissolution and reprecipitation. These findings provide insights into the incorporation of trace elements in natural biominerals and their hierarchical ultrastructure.

Summary: Understanding the chemical events following trauma to the central nervous system could help identify causative mechanisms and potential interventions for protecting neural tissue. In a rat model of partial optic nerve transection injury, researchers used synchrotron X-ray fluorescence microscopy to map the distribution of metals and related elements in white matter tracts. The study found significant changes in copper levels and widespread metal imbalance in response to central nervous system trauma, suggesting that metal homeostasis may be a potential target for intervention in limiting damage following neural injuries.

Summary: Artisanal and small-scale gold mining (ASGM) is the leading global source of anthropogenic mercury (Hg) release to the environment. To support future inquiry, we identify key knowledge gaps including the role of Hg-CN complexes in mercury oxidation, transport, and fate, and possible links to mercury methylation. The global extent and increase of mercury and cyanide processing in ASGM underscores the importance of further research.

Summary: DNA G-quadruplexes (G4s) have been identified as important targets for regulating gene expression and treating human diseases. Two ligands, GTC365 and GQC-05, were found to stabilize G4s with different specificities, leading to altered chromatin accessibility and modified DNA damage response pathways. This work highlights the potential of G4-stabilizing ligands for specific or global chromatin modulation.
