Layer-by-layer assembly of nanotheranostic particles for simultaneous delivery of docetaxel and doxorubicin to target osteosarcoma.

Osteosarcoma (OS) is a rare form of primary bone cancer, impacting approximately 3.4 × 10 individuals worldwide each year, primarily afflicting children. Given the limitations of existing cancer therapies, the emergence of nanotheranostic platforms has generated considerable research interest in recent decades.

Characterization of the Shells in Layer-By-Layer Nanofunctionalized Particles: A Computational Study.

Drug delivery carriers are considered an encouraging approach for the localized treatment of disease with minimum effect on the surrounding tissue. Particularly, layer-by-layer releasing particles have gained increasing interest for their ability to develop multifunctional systems able to control the release of one or more therapeutical drugs and biomolecules. Although experimental methods can offer the opportunity to establish cause and effect relationships, the data collection can be excessively expensive or/and time-consuming.

Energy approach to brittle fracture in strain-gradient modelling.

In this paper, we exploit some results in the theory of irreversible phenomena to address the study of quasi-static brittle fracture propagation in a two-dimensional isotropic continuum. The elastic strain energy density of the body has been assumed to be geometrically nonlinear and to depend on the strain gradient. Such generalized continua often arise in the description of microstructured media.

An alternative expeditious analysis of phospholipid composition in human blood plasma by 31P NMR spectroscopy.

31P nuclear magnetic resonance spectroscopy has been applied to quantitate phospholipids in human blood plasma and in separate lipoprotein fractions. The addition of suitable detergents to samples produces an excellent chemical shift dispersion and allows the identification and integration of the peaks of the most important phospholipids. Results are in agreement with those obtained with enzymatic colorimetric and TLC methods: our method is characterized by good accuracy and reproducibility.

High-resolution 1H NMR spectroscopy in the diagnosis of breast cancer.

Surgical specimens from 22 patients with infiltrating ductal carcinoma of the breast were analyzed by high-resolution 1H NMR spectroscopy at 80 and 300 MHz. Results were compared with those obtained from 9 benign (proliferative dysplasia without atypia) breast samples. NMR spectra at 80 MHz showed well-resolved water and lipid peaks so it was possible to calculate specific T1 and T2 relaxation times.
