Abstract Background Gastric cancer (GC) remains a major global health challenge with persistently poor survival rates, largely attributable to late-stage diagnosis and the inherent limitations of conventional imaging mod...

Raman scattering can provide information on molecular fingerprints, which have been widely applied in various fields of material science and nanobiotechnology. Notably, low interference with water molecules in obtaining ...

Abstract Edible insects are gaining popularity as a potential future food source because of their high protein content and efficient use of space. Black soldier fly larvae (BSFL) are noteworthy because they can be used a...

The increasing complexity of composite materials structured on the nanometer scale requires highly sensitive analytical tools for nanoscale chemical identification, ideally in three dimensions. While infrared near-field ...

Understanding the nutritional physiology of mosquito larvae is crucial for optimizing massrearing practices and improving control strategies. Here we combined complementary opticaland spectroscopic techniques, including ...

Background and purpose: Volumetric Interpolated Breath-hold Examination (VIBE) magnetic resonance imaging (MRI) can depict flap applicators of High-Dose-Rate (HDR) surface brachytherapy. Evaluating criteria for catheter ...

INFN-CHNet is the cultural heritage network of the Italian National Institute of Nuclear Physics (INFN) and is constituted by units from Italy and from outside Europe, one of them at Universidad Nacional de San Martín (...

Abstract Background We previously reported the first-in-human evaluation of 3-[18F]-fluoro-2,2-dimethylpropionic acid ([18F]FPIA) for imaging aberrant lipid metabolism and cancer detection. The first-generation semi-auto...

Reporter-based assays underlie many high-throughput screening (HTS) platforms, but most are limited to in vitro applications. Here, we report a simple whole-organism HTS method for quantifying changes in reporter intensi...

Biogenic amine neurotransmitters play a central role in metazoan biology, and both their chemical structures and cognate receptors are evolutionarily conserved. Their primary roles are in cell-to-cell signaling, as bioge...

Chirality prevails in nature and is of great value for molecular biology, medicine, and bioscience. Due to the enhancement of chiroptical responses, chiral metasurfaces has attracted enormous attentions. In this paper, s...

Upconverting luminescent nanoparticles are photostable, nonblinking, and low chemically toxic fluorophores that are emerging as promising fluorescent probes at the single molecule level. High luminescence intensity upcon...

الملخص: أهداف البحث: هدفت هذه الدراسة إلى مقارنة تأثير دمج الألياف الزجاجية المعالجة مسبقًا بالسيلان، سواء التجارية (Stick...

As an aircraft component is subjected to tensile/torsional/bending forces and heat cycles during operation, non-destructive inspection programs have been mandated by aviation regulatory authorities and component manufact...

The race for continuous scaling has been fuelling the electronics industry for the last half a century, allowing unprecedented innovations and achievements. Undoubt‐ edly, silicon and, to some extent, III-V semiconduct...

Illumination of noble metal nanostructures by electromagnetic radiation induces coherent oscillations of conductive electrons on their surfaces. These coherent oscillations of electrons, also known as localized surface p...

Abstract The recent cataloging of global microseisms benefits imaging of the Earth's interior with improved data coverage. Relying on the catalog, converted waves were extracted and employed to reveal variations of the m...

Abstract Background Neutrophils (polymorphonuclear leukocytes, PMNs) have long been underestimated in the context of autoimmunity. To elucidate their role from a sex-specific perspective, an immunoendocrinological framew...

Needle-like electromagnetic field has various advantages for the applications in high-resolution imaging, Raman spectroscopy, as well as long-distance optical transportation. The realization of such field often requires ...

Abstract Medicine is evolving beyond therapy largely predicated on anatomical information and towards incorporating patient-specific molecular biomarkers of disease for more accurate diagnosis and effective treatment. Th...
