Boron neutron capture therapy (BNCT) targets invasive, radioresistant cancers but requires a selective and high B-10 loading boron drug. This manuscript investigates boron-rich poly(ethylene glycol)-block-(poly(4-vinylphenyl boronate ester)) polymer micelles synthesized via atom transfer radical polymerization for their potential application in BNCT. Transmission electron microscopy (TEM) revealed spherical micelles with a uniform size of 43 ± 10 nm, ideal for drug delivery. Additionally, probe sonication proved effective in maintaining the micelles’ size and morphology postlyophilization and reconstitution. In vitro studies with B16-F10 melanoma cells demonstrated a 38-fold increase in boron accumulation compared to the borophenylalanine drug for BNCT. In vivo studies in a B16-F10 tumor-bearing mouse model confirmed enhanced tumor selectivity and accumulation, with a tumor-to-blood (T/B) ratio of 2.5, surpassing BPA’s T/B ratio of 1.8. As a result, mice treated with these micelles experienced a significant delay in tumor growth, highlighting their potential for BNCT and warranting further research. © 2024 The Authors.

Neutrosophic Non-Newtonian and Geometric Measures: A Consistent Analytical Framework

引用

Neutrosophic Sets and Systems 2025年 80卷 350-376页

The neutrosophic measure is a generalization of the classical measure in situations when the space contains some indeterminacy. In this paper, we introduce the concept of the Neutrosophic Geometric Measure, we also provide some results, and examples related to the Neutrosophic Geometric Measure. A classical measure of the object’s determinate component, a classical measure of its indeterminate part, and a further classical measure of the object’s opposite determinate part are the three classical measures that make up the neutrosophic measure. To define the Neutrosophic Geometric Measure, we introduce a new measure on R+ and call it the geometric Lebesgue measure. The geometric Lebesgue measure is defined, and some of its properties are examined and detailed. Moreover, we establish a relation between the Lebesgue measure and geometric Lebesgue measure to see if the properties of Lebesgue measure are still true in this new measure. Other basic topics discussed in this paper are geometric measurable function and the geometric simple approximation Theorem. © 2025, University of New Mexico. All rights reserved.

3D printing (3DP) ranks as one of the more advanced methods in the manufacturing sector. All of the industrial sectors, including automobiles, medical services, aviation, athletics, fabrics, apparel, and fashion industries, have noticed an increase in the use of this approach for prototyping. In the past decade, 3DP technology has been applied in several industries by academics, textile technologists, designers of apparel, manufacturers, and suppliers. Textiles perform numerous purposes in addition to meeting the basic human need to protect the body. The textile industry has expanded its horizons with the incorporation of 3DP technology. This paper's goal is to present an integrated overview of the recent state of research to identify the most advanced 3DP techniques, materials, and applications currently used in the clothing and textile sectors. Fundamentals of basic textile substrates, numerous textile-related 3DP technologies, printing methods, materials for print inks, direct printing of 3D elements on different textile surfaces, and the impacts, benefits and limitations of 3D printed textile structure fabrication techniques are all addressed. It also emphasizes the ways 3DP technology will be used in the textile sector moving forward. Overall, the purpose of this issue of Textile Progress is to identify the potential of 3DP, which, despite certain limits, may improve the products of the fashion and textile sectors and encourage future scientists and designers to continue additional research. © 2025, idd3.
