Focused ion beam (FIB) prepared microtextured microneedle array capable of delivering drugs through punctured skin.

Microtextured microneedles are tiny needle-like structures with micron-scale microtextures, and the drugs stored in the microtextures can be released after entering the skin to achieve the effect of precise drug delivery. In this study, the skin substitution model of Ogden's hyperelastic model and the microneedle array and microtexture models with different geometrical parameters were selected to simulate and analyse the flow of the microtexture microneedle arrays penetrating the skin by the finite-element method, and the length of the microneedles was determined to be 200 μm, the width 160 μm, and the value of the gaps was determined to be 420 μm. A four-pronged cone was chosen as the shape of microneedles, and a rectangle was chosen as the shape of the drug-carrying microneedle.

[Determination of 12 halogenated organic pollutants in edible fish by ultra performance liquid chromatography-high resolution mass spectrometry combined with ultrasound-assisted extraction and gel permeation chromatography purification].

Halogenated organic pollutants (HOPs) have attracted considerable attention owing to their persistence, bioaccumulation, and toxicity. The development of methods to detect HOPs in fish is challenging owing to the compositional complexity of fish matrices, which contain high levels of lipids and relatively low concentrations of HOPs. In addition, the lipophilicity of most HOPs renders their extraction difficult.

Proportional Ear Reduction: The Rule of Threes.

Background: Human ear growth continues beyond puberty, resulting in ears that are typically approximately 10 millimeters (mm) larger in older individuals compared to their younger counterparts. Not only is the overall growth of the ear an indicator of age, but also the disproportionate growth of its parts. The largest part, the concha, shows the slowest growth rate, while the smallest part, the earlobe, shows the greatest growth rate.

vCPP2319 interacts with metastatic breast cancer extracellular vesicles (EVs) and transposes a human blood-brain barrier model.

Brain metastases (BM) are frequently found in cancer patients and, though their precise incidence is difficult to estimate, there is evidence for a correlation between BM and specific primary cancers, such as lung, breast, and skin (melanoma). Among all these, breast cancer is the most frequently diagnosed among women and, in this case, BM cause a critical reduction of the overall survival (OS), especially in triple negative breast cancer (TNBC) patients. The main challenge of BM treatment is the impermeable nature of the blood-brain barrier (BBB), which shields the central nervous systems (CNS) from chemotherapeutic drugs.
