Developmental venous anomaly (DVA) is a common benign brain vascular malformation, typically asymptomatic, with intervention required when complications arise. We present the case of a 63-year-old man with mild cognitive decline whose brain FDG PET showed decreased uptake not only at the site of DVA, but in the extended surrounding parenchyma where MRI showed no parenchymal abnormalities. DVAs arise from developmental irregularities in the embryonic venous system, but likely affecting a greater extent of the surrounding parenchymal functions.

The emerging combination of chemotherapy and radionuclide therapy has been actively investigated to overcome the limitations of monotherapy and augment therapeutic efficacy. However, it remains a challenge to design a single delivery vehicle that can incorporate chemotherapeutics and radionuclides into a compact structure. Here, a chelator DOTA- or NOTA-modified Evans blue conjugated camptothecin molecule (EB-CPT) nanoprodrug was synthesized, which could self-assemble into nanoparticles due to its inherent amphiphilicity.

Purpose: It was noticed that anterior choroidal artery (AChoA) aneurysms appear to rupture at relatively smaller sizes compared with aneurysms in other intracranial locations, based on anecdotal clinical experience. We therefore aimed to compare ruptured AChoA aneurysms with other ruptured aneurysms in other intracranial locations, pertaining to aneurysm dimensions. This may help in finding out if the rupture risk stratification, based on the amalgamation of aneurysms of multiple locations in one group, precisely estimates aneurysm rupture risk.

Flat bands have empowered novel phenomena such as robust canalization with strong localization, high-collimation and low-loss propagation. However, the spatial symmetry protection in photonic or acoustic lattices naturally forces flat bands to manifest in pairs aligned at an inherently specific angle, resulting in a fixed bidirectional canalization. Here, we report an acoustic flat-band metasurface, allowing not only unidirectional canalization at all in-plane angles but also robust tunability in band alignment.

Background: Singapore's large aging population poses significant challenges for the health care system in managing cognitive decline, underscoring the importance of identifying and implementing effective interventions. Cognitive training delivered remotely as a digital therapeutic (DTx) may serve as a scalable and accessible approach to overcoming these challenges. While previous studies indicate the potential of cognitive training as a promising solution for managing cognitive decline, understanding the attitudes and experiences of older adults toward using such DTx platforms remains relatively unexplored.

Mitochondrial quality control is paramount for cellular development, with mitochondrial electron flow (Mito-EF) playing a central role in maintaining mitochondrial homeostasis. However, unlike visible protein entities, which can be monitored through chemical biotechnology, regulating mitochondrial quality control by invisible entities such as Mito-EF has remained elusive. Here, a Mito-EF tracker (Mito-EFT) with a four-pronged probe design is presented to elucidate the dynamic mechanisms of Mito-EF's involvement in mitochondrial quality control.

Due to the global demands on carbon neutralization, CO separation membranes, particularly those based on two-dimensional (2D) materials, have attracted increasing attention. However, recent works have focused on the chemical decoration of membranes to realize the selective transport, leading to the compromised stability in the presence of moisture. Herein, we develop a series of 2D capillaries based on layered double hydroxide (LDH), graphene oxide, and vermiculite to enhance the oversaturation of CO in the confined water for promoting the membrane permselectivity.

If that is correct, then perhaps psychedelics should be treated differently from other medical substances: for example, by being subjected to different ethical or evidentiary standards. Alternatively, it may be that psychedelics have more in common with various existing medical interventions than first meets the eye.

For the past 50 years, significant progress has been made in understanding Seasonal Hyperacute Panuveitis (SHAPU), a mysterious blinding disease first reported in Nepal in 1975. Predominantly affecting Nepalese children, SHAPU occurs cyclically every odd year from September to December. While initially misclassified as endophthalmitis, SHAPU is set apart by its lack of trauma or surgery, failure to grow organisms in most intraocular fluid cultures, and its hallmark presentation of a "white pupil in red eye" with an association with moth exposure.

Tumor-promoting inflammation significantly impacts cancer progression, and targeting inflammatory cytokines has emerged as a promising therapeutic approach in clinical trials. Interleukin (IL)-1α, a member of the IL-1 cytokine family, plays a crucial role in both inflammation and carcinogenesis. How IL-1α is secreted in the tumor microenvironment has been poorly understood, and we previously showed that calpain 1 cleaves pro-IL-1α for mature IL-1α secretion, which exacerbates hepatocellular carcinoma by recruiting myeloid-derived suppressor cells.
