Inorganic Nanomaterials can Promote or Inhibit Tumor Metastasis Depending on Tumor Microenvironment Composition

Advanced Science, EarlyView.
As engineered nanomaterials gain prominence in cancer imaging and therapy, understanding their impact on tumor progression becomes increasingly critical. We demonstrate that gold and silica‐coated gold nanomaterials can either suppress or enhance breast cancer metastasis through distinct tumor microenvironment interactions, while identifying ...

WITHDRAWING TREATMENT AND KILLING: THE WAYS TO DISTINGUISH

Вісник Харківського національного університету імені В.Н. Каразіна. Серія Філософія, філософські перипетії, 2020
One of the key problems facing bioethics concerns those cases where, due to the limited human and technical resources of medicine, patients are in fact doomed to die.

Hyper‐Intense Tumor Peripheral Accumulation of Antibody‐Conjugated Iron Oxide Nanoparticles can Enable Breast Cancer Detection by Magnetic Particle Imaging

Advanced Science, EarlyView.
Tumor‐associated inflammation retains antibody‐targeted or non‐specific antibody conjugated nanoparticles within the tumor microenvironment. Magnetic Particle Imaging (MPI) enables non‐invasive detection and differentiation of tumors from other organs, owing to higher nanoparticle retention by inflammatory cells in the tumor periphery.

On the Assumed Moral Superiority of Passive over Active Euthanasia [PDF]

Since the inception of the euthanasia debate, the differentiation be-tween active and passive euthanasia – distinguishing between “let-ting die” and “actively killing” – has emerged as a central point of contention. In this paper, we will contend that: a)

Radiation‐Triggered Chemokine‐Secreting Probiotics for Boron Neutron Capture Therapy Based Radioimmunotherapy

Advanced Science, EarlyView.
Engineered Escherichia coli Nissle 1917 with a tannic acid‐mediated BPA coating enables tumor‐targeted boron delivery for BNCT. The low‐level incidental radiation generated during BNCT activate a RecA‐driven circuit to induce CXCL10, while radiation‐enhanced bacterial colonization triggers in situ vaccination and systemic antitumor immunity.

Intelligent Programmable Membrane Nanosponge for Early Virus Blocking

Advanced Science, EarlyView.
A smart programmable nanosponge (ACNPs) displays high‐density viral receptors on its membrane and encapsulates fusion inhibitors to capture virions at the infection source through competitive binding and blocks their entry through protease inhibition for ultra‐early cascade interception. This modular, mucus‐penetrating platform shifts antiviral defence
