The purpose of this work comprise the assessment of the antioxidant activity of total anthocyanins from Perilla pankinensis samples (TAPP) by different analytical methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, total antioxidant activity, total reducing activity, superoxide anion radical scavenging, hydrogen peroxide scavenging and metal chelating activities. Total antioxidant activity was measured according to ferric thiocyanate method. alpha-Tocopherol and trolox, which water-soluble analogue of tocopherol were used as references antioxidant compounds. At the concentrations of 30 and 45 microg/mL, TAPP showed 91.9 and 96.4% inhibition on lipid peroxidation of linoleic acid emulsion, respectively. In comparison, 45 microg/mL of standard antioxidant such as alpha-tocopherol and trolox exhibited 88.8 and 86.2% inhibition on peroxidation of linoleic acid emulsion, respectively. In addition, TAPP have found effective on DPPH scavenging, superoxide anion radical and hydrogen peroxide scavenging, total reducing power and metal chelating on ferrous ions activities. Also, these various antioxidant effects were compared to alpha-tocopherol and trolox.

This study aimed to investigate the effect of tumor lysis syndrome (TLS) on the prognosis of children and adolescents with intermediate- or high-risk high-grade mature B-cell nonHodgkin lymphoma (HG B-NHL) . This study collected the clinical data and prognosis of 283 patients aged <18 years with newly diagnosed intermediate- or high-risk HG B-NHL treated at the Sun Yat-sen University Cancer Center from January 2010 to December 2022. The clinical characteristics, laboratory indicators during TLS, and prognosis of the patients were analyzed.

Proteins and polyphenols exhibit distinct biological activities and functional properties. A comprehensive investigation into the formation mechanisms, structures, and functional properties of protein-polyphenol complexes will deepen our understanding of their interactions and establish a theoretical foundation and technical support for development of novel functional foods and pharmaceutical products. The almond protein-phloretin (AP-PHL) covalent complex was synthesized through the covalent binding of hydroxyl radicals to phloretin (PHL), utilizing almond protein (AP) as the raw material.

Background: Telomere maintenance is an important feature of tumor cells. Telomeric-repeat binding factor 1 interaction nuclear protein 2 (TIN2), a key member of the shelterin proteins, functions in regulating telomere structure, length and function. Our work sought to investigate the role of TIN2 in controlling gastric cancer (GC) malignant biological behaviors.

The expanded lethal (2) essential for life [l(2)efl] gene family is responsive to proteostatic stresses. Their protein products are core components of the stress response mechanism and are emerging as promising biomarkers for cellular stress in Apis mellifera. However, l(2)efl (LOC410857) uniquely remains unresponsive to heat stress within this gene family, and research examining its role in adaptation to other types of stress across diverse bee species is scarce.
