Standardized Response Assessment in Patients with Advanced Cholangiocarcinoma Treated with Personalized Therapy.

: Current guidelines recommend Cisplatin/Gemcitabine/Durvalumab as first-line treatment for inoperable or recurrent cholangiocarcinoma (CCA). Molecular tumor boards (MTB) have the expertise to support organ-specific tumor boards with evidence-based treatment recommendations for subsequent lines of treatment, based on genomic tumor data and scientific evidence. This study evaluates the adoption of an MTB at a comprehensive cancer center in Germany and whether actionable genetic alterations are associated with specific imaging phenotypes.

Tin prefiltration in computed tomography does not significantly alter radiation-induced gene expression and DNA double-strand break formation.

Background: The tin (Sn) prefilter technique is a recently introduced dose-saving technique in computed tomography (CT). This study investigates whether there is an altered molecular biological response in blood cells using the tin prefiltering technique.

Methods: Blood from 6 donors was X-irradiated ex-vivo with 20 mGy full dose (FD) protocols (Sn 150 kV, 150 kV, and 120 kV) and a tin prefiltered 16.

Folic Acid-Intercalated Mg/Al Layered Double Hydroxides-A Multifunctional Nanohybrid Delivery System for Topical Applications.

The delivery of active functional molecules across the skin is laborious due to its structural intricacy and exceptional barrier characteristics. Developments in nanotechnology yielded innovative transport vehicles derived from nanomaterials to reinforce the skin's ability to interact with active ingredient molecules and increase its bioavailability. The current study employed crystalline inorganic two-dimensional double hydroxides (LDHs) as an efficient carrier and delivery vehicle for folic acid (FA) in a topical skincare formulation.

An In Vitro-In Vivo Comparative Study Using Highly Sensitive Radioisotopic Assays to Assess the Predictive Power of Emerging Blood-Brain Barrier Models.

Microfluidic BBB-on-a-chip models (μBBB) aim to recapitulate the organotypic features of the human BBB with great potential to model CNS diseases and advance CNS therapeutics. Nevertheless, their predictive capacity for drug uptake into the brain remains uncertain due to limited evaluation with only a small number of model drugs. Here, the in vivo brain uptake of a panel of nine radiolabeled compounds is evaluated in Swiss-outbred mice following a single intravenously administered dose and compared against results from the microfluidic μBBB platform and the conventional Transwell BBB model.

Replication Restriction of Influenza A(H5N1) Clade 2.3.4.4b Viruses by Human Immune Factor, 2023-2024.

We show that human myxovirus resistance protein 1 (MxA) suppresses replication of highly pathogenic avian influenza A(H5N1) viruses isolated from mammals in vitro and in MxA-transgenic mice. However, H5N1 can evade MxA restriction through replacement of individual viral polymerase complex components from a human-adapted MxA-resistant strain in vitro.
