Purpose: To evaluate the association of lipid profile and statin therapy with stroke severity and early functional outcome in anticoagulated patients with atrial fibrillation (AF) hospitalized with acute ischemic stroke ...

Background: Melanoma represents a highly aggressive and metastatic form of malignant skin cancer. that remains challenging to treat clinically. Tumor cells often reprogram nicotinamide adenine dinucleotide (NAD⁺) metab...

Abstract Objective Photon-counting CT (PCCT) combines improved dose efficiency with spectral imaging, enabling dynamic functional imaging at chest CT dose levels. Dual energy CT typically uses perfused blood volume (PBV)...

Van der Waals (vdW) magnetic materials offer a flexible platform for exploring low-dimensional spin-dependent transport. FePd _2 Te _2 (FPT) is a layered ferromagnet with a Curie temperature of ∼185 K, whose magnetic a...

ObjectiveThe method of high performance liquid chromatography （HPLC） was developed to study the detection of synthetic colorants in natural pigments and condiment.MethodsThe analytes were extracted by direct ultrason...

Zirconia (ZrO2) is of great importance as a support for systems where high ionic conductivity and mechanical stability are required. Doping/defects have a significant effect on the physical properties of this oxide by st...

The extremely high peak intensity associated with ultrashort pulse width of femtosecond laser allows us to induce nonlinear interaction such as multiphoton absorption and tunneling ionization with materials that are tran...

Abstract Background Fatigue is the main complaint of 5–10% of patients in primary care and is often associated with significant suffering and functional disability. Cognitive behavioral therapy (CBT) has demonstrated e...

With their ultrathin characteristics as well as the powerful and flexible capabilities of wavefront modulation, optical metasurfaces have brought a new understanding of the interaction between light and matter and provid...

Spelt husk material is a novel packaging solution intended for equal applications as packaging made of expanded polystyrene (EPS). In the future, husk packaging could therefore at least partially substitute plastics in t...

This study investigates how four nano-additives, namely graphene, amine-functionalized graphene, hexagonal boron nitride (hBN), and multi-walled carbon nanotubes, affect the properties of polylactic acid (PLA) used in ma...

This paper presents a study of adsorption and vibrational features of folic acid, using surface-enhanced Raman scattering (SERS). A gold-capped silicon nanopillar (Au NP) with a height of 600 nm and a width of 120 nm was...

Understanding solute segregation at twin boundaries (TBs) is essential for tailoring the microstructure and properties of magnesium alloys. Using in situ scanning transmission electron microscopy, we directly observe the...

Abstract Angle-resolved photoemission spectroscopy is a powerful experimental technique for studying anisotropic many-body interactions through the electron spectral function. Existing attempts to decompose the spectral ...

In this article, a model-based genetic algorithm is used to determine the optical properties of nanostructured zinc oxide single-sided nano thin films that does not depend on the interference fringes of optical transmiss...

Abstract The interplay between strong electronic correlations, unconventional superconductivity, and symmetry-protected topology provides a fertile ground for discovering exotic quantum states. In this work, we investiga...

In this investigation, differently shaped and surface functionalized TiO2 anatase nanoparticles and human serum albumin (HSA) were selected to study protein- nanoparticles interaction both in a solution and on flat surfa...

In this study, nano-carbonated hydroxyapatite (n-CHAp) was successfully synthesized with abalone shells ( Halioitis asinina ) as the calcium source using precipitation methods with aging time variations, namely, 0 (witho...

Amyloids constitute a class of protein and protein fragments believed to be involved in the pathologies associated with Alzheimer’s, Parkinson’s and Creutzfeldt‐ Jakob diseases. These proteins can self‐assemble i...

Upconversion nanoparticles (UCNs) find application in nanomedicine as biolabels to identify cancer cells. In this work, Y2O3: Er3+/ Yb3+ and Gd2O3: Er3+/ Yb3+ systems were fabricated by combustion synthesis (CS) and sol-...

Gold nanoparticles have many applications in the biomedical field, mainly for drug delivery, cancer therapy, and detection of pathogenic microorganisms. In this study, gold nanoparticles synthesized using Platycodon gran...

We present a unified scheme that, by combining molecular dynamics and density-functional theory, profoundly extends the range of both concepts. Our approach extends molecular dynamics beyond the usual pair-potential appr...
