A Multiyear Longitudinal Harmonization Study of Quality Controls in Mass Spectrometry Proteomics Core Facilities.

Quality control procedures play a pivotal role in ensuring the reliability and consistency of data generated in mass spectrometry-based proteomics laboratories. However, the lack of standardized quality control practices across laboratories poses challenges for data comparability and reproducibility. In response, we conducted a harmonization study within proteomics laboratories of the Core for Life alliance with the aim of establishing a common quality control framework, which facilitates comprehensive quality assessment and identification of potential sources of performance drift.

Near-field enhancement of light by higher-order multipole excitations in a metal nanodisc trimer.

Near-field enhancement of light by dipole excitations in plasmonic nanoparticles plays an important role in many applications of optical nanotechnology, including solar cells, plasmonic sensors, and nonlinear optical devices. Recently, we have shown that a seemingly weak octupole resonance in a pair of metal nanospheres can provide a higher near-field enhancement than the dipole resonance. Being motivated by this discovery, we now design a plasmonic nanodisc trimer that supports hybridized higher-order excitations and simultaneously suppresses the dipole excitation.

Stability of inorganic ionic structures: the uniformity approach.

The crystal structure uniformity is numerically estimated as the standard deviation of the crystal space quantizer 〈G〉. This criterion has been applied to explore the uniformity of ionic sublattices in 21465 crystal structures of inorganic ionic compounds. In most cases, at least one kind of sublattice (whole ionic lattice, cationic or anionic sublattice) was found to be highly uniform with a small 〈G〉 value.

Hepatocyte differentiation requires anisotropic expansion of bile canaliculi.

During liver development, bipotential progenitor cells called hepatoblasts differentiate into hepatocytes or cholangiocytes. Hepatocyte differentiation is uniquely associated with multi-axial polarity, enabling the anisotropic expansion of apical lumina between adjacent cells and formation of a three-dimensional network of bile canaliculi. Cholangiocytes, the cells forming the bile ducts, exhibit the vectorial polarity characteristic of epithelial cells.

Therapeutic Potential of a Biodynamic Supplement on Skin Pressure Ulcers: A Randomized Clinical Study.

Pressure ulcers (PUs) are a debilitating and often painful condition. They are localized lesions on the skin and/or underlying tissues and are common in the elderly, people with mobility difficulties, diabetics, and vascular disease or malnutrition, as well as in those requiring intensive or palliative care. The prevention and treatment of PUs involve strategies to optimize hydration, circulation, and nutrition.
