About the sonoluminescent spectral portrait of gasoline water pollution.

Single-bubble sonoluminescence spectra of the following samples were recorded in the modes of standing and moving bubble in liquid near the center of its levitation under the action of ultrasound: water contaminated with additives of commercial gasoline (1.5 - 38 mg·L), water with additives of individual gasoline components (hexane, benzene, toluene, p-xylene, naphthalene, anthracene, and p-terphenyl), and solutions of these gasoline components in hexane. Characteristic bands λ of gasoline component emitters are recorded in the sonoluminescence spectra of a moving bubble for water samples contaminated with additives of commercial gasoline: 290 (p-xylene), 340 (p-terphenyl), 381, 399, 424, 449 (anthracene), and 438, 474, 516, 564 nm (C, a hydrocarbon decomposition product during sonolysis).

Small protein blockers of human IL-6 receptor alpha inhibit proliferation and migration of cancer cells.

Background: Interleukin-6 (IL-6) is a multifunctional cytokine that controls the immune response, and its role has been described in the development of autoimmune diseases. Signaling via its cognate IL-6 receptor (IL-6R) complex is critical in tumor progression and, therefore, IL-6R represents an important therapeutic target.

Methods: An albumin-binding domain-derived highly complex combinatorial library was used to select IL-6R alpha (IL-6Rα)-targeted small protein binders using ribosome display.

Engineering PD-1-targeted small protein variants for in vitro diagnostics and in vivo PET imaging.

Background: Programmed cell death 1 (PD-1) belongs to immune checkpoint proteins ensuring negative regulation of the immune response. In non-small cell lung cancer (NSCLC), the sensitivity to treatment with anti-PD-1 therapeutics, and its efficacy, mostly correlated with the increase of tumor infiltrating PD-1 lymphocytes. Due to solid tumor heterogeneity of PD-1 populations, novel low molecular weight anti-PD-1 high-affinity diagnostic probes can increase the reliability of expression profiling of PD-1 tumor infiltrating lymphocytes (TILs) in tumor tissue biopsies and in vivo mapping efficiency using immune-PET imaging.

Perceived Value of a Women's Health Journal Club in Rural Hawai'i.

Objectives: Rural Hawai'i faces a shortage of physicians specializing in women's health. Improving clinician collaboration and access to the scientific literature are potential strategies for improving physician retention in this community. In 2021, a monthly women's health journal club was established for local clinicians and trainees on Hawai'i Island.

Application of Sonotriboluminescence to Determine Arene Molecules in Hydrocarbons.

The sonotriboluminescence of suspensions of terbium(III) and europium(III) sulfates in decane without and in the presence of benzene, toluene and -xylene was studied. The choice of crystals of these lanthanides is due to the fact that they have intense luminescence during mechanical action, and also do not dissolve in hydrocarbon solvents. During ultrasonic exposure to suspensions in pure alkanes, bands of Ln ions and N in the UV region are recorded in the luminescence spectrum.
