Pulsatile sequential drug release system for cascade tumor deep penetration and differentiation therapy to enhance chemoimmunotherapy

Fengxiang Liu, Shipeng Ning, Xia Wang et al. · 2025 · Science Advances

Cancer stem cells (CSCs) and myeloid-derived suppressor cells (MDSCs) contribute to chemoresistance and immunosuppression, constraining chemoimmunotherapy outcomes. Differentiation therapy, aiming to mature CSCs and MDSCs, shows great promise. However, its efficacy is hindered by limited accessibility in hypoxic deep tumor regions. Inspired by the apoptotic body (ApoBD)-mediated deep tumor penetration, we design a pulsatile sequential drug release system with a core-shell structure. The reversible acid-responsive shell protonates and swells in lysosomes to release doxorubicin, inducing lysosom

NANO-LM: An updated scorecard for the clinical assessment of patients with leptomeningeal metastases

Émilie Le Rhun, Lakshmi Nayak, Mary Jane Lim-Fat et al. · 2024 · Neuro-Oncology

BACKGROUND: There are no validated tools for the clinical neurological assessment of patients with leptomeningeal metastases (LM). However, clinical examination during the course of the disease guides medical management and is part of response assessment in clinical trials. Because neuroimaging may not always be obtained owing to rapid clinical deterioration, clinical neurological assessment of LM is essential, and standardization is important to minimize rater disagreement. METHODS: The Response Assessment in Neuro-oncology-LM group launched a 2-step process, aiming at improving and standardi

The Functional Role of Polyphenols Across the Human Lifespan

Bekir Enes Koca, Sümeyye Sarıtaş, Mikhaël Bechelany et al. · 2025 · International Journal of Molecular Sciences

Polyphenols are bioactive molecules that occur naturally in plants and exhibit a diverse array of properties, including antioxidant, anti-inflammatory, and anti-obesity effects, all of which have been supported by numerous studies. They are categorized into four main groups: flavonoids, phenolic acids, stilbenes, and lignans. Polyphenols demonstrate a wide range of health-promoting effects throughout human life, from the womb to old age. They can exert these effects by modulating signaling pathways, regulating gut microbiota, influencing gene expression, and regulating epigenetic pathways. Thi

Oxygen level alters energy metabolism in bovine preimplantation embryos

Nina Boskovic, Marilin Ivask, Gamze Yazgeldi Gunaydin et al. · 2025 · Scientific Reports

Abstract Mammalian preimplantation embryo development is a complex sequence of events. This period of development is sensitive to oxygen (O 2 ) levels that can affect various cellular processes. We compared the influence of O 2 tension by culturing embryos either in normoxic (20% O 2 ) or physiological hypoxic (6% O 2 ) conditions, or sequential low O 2 concentration starting with 6% O 2 until 16-cell stage and then switching to ultrahypoxic conditions (2% O 2 ). Due to ethical concerns, we used bovine as an animal model with a good similarity of embryogenesis to human. We found that the cleav

An App Call a Day Keeps the Patient Away? Substitution of Online and In-Person Doctor Consultations Among Young Adults

Lina Maria Ellegård, Gustav Kjellsson, Linn Mattisson · 2026 · The Economic Journal

Abstract The emergence of markets for on-demand online physician consultations —direct-to-consumer telemedicine (DCT) — is currently transforming many healthcare settings. DCT may be a cost-effective substitute for in-person consultations, but the convenience of seeking DCT may increase the demand for the service and consequently also the costs for health insurers. To causally assess the degree to which DCT consultations substitute for in-person primary care consultations, we exploit exogenous changes in patient fees in a fuzzy difference-in-discontinuities analysis of young adults in Sweden.

The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the X-Rays and Radio

A. J. Nayana, R. Margutti, Eli Wiston et al. · 2025 · The Astrophysical Journal Letters

Abstract We present X-ray (0.3–79 keV) and radio (0.25–203 GHz) observations of the most luminous fast blue optical transient (LFBOT) AT 2024wpp at z = 0.0868, spanning 2–280 days after first light. AT 2024wpp shows luminous ( L X ≈ 1.5 × 10 43 erg s −1 ), variable X-ray emission with a Compton hump peaking at δt ≈ 50 days. The X-ray spectrum evolves from a soft ( F ν ∝ ν −0.6 ) to an extremely hard state ( F ν ∝ ν 1.26 ) accompanied by a rebrightening at δt ≈ 50 days. The X-ray emission properties favor an embedded high-energy source shining through asymmetric expanding ejecta. We detect radi
