When chrysotile fibers treated with Portland cement, Mg was partially substituted by Ca, therefore monolayer of Ca(OH)2 was formed as a cover, and that changed acidity force, number of active centers and biological activity (absent mutageneity, generation of active oxygen forms by macrophages was characterized by lower maximum and longer time to background level vs. native chrysotile).

Background: Liver malignancies present substantial challenges to surgeons due to the extensive hepatic resections required, frequently resulting in posthepatectomy liver failure. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was designed to increase the resectable liver volume, yet it is associated with significant mortality and morbidity rates. Recently, minimally invasive techniques have been incorporated into ALPPS, with the potential to improve the procedure's safety profile whilst maintaining efficacy.

Background: Risk factors and mechanisms of cognitive impairment (CI) after aneurysmal subarachnoid hemorrhage (aSAH) are unclear. This study used a neuropsychological battery, MRI, ERP and CSF and plasma biomarkers to predict long-term cognitive impairment after aSAH.
Materials And Methods: 214 patients hospitalized with aSAH (n = 125) or unruptured intracranial aneurysms (UIA) (n = 89) were included in this prospective cohort study.

The Ni-N(His) coordination bond, formed between the nickel ion and histidine residues, is essential for recombinant protein purification, especially in Ni-NTA-based systems for selectively binding polyhistidine-tagged (Histag) proteins. While previous studies have explored its bond strength in a synthetic Ni-NTA-Histag system, the influence of the surrounding protein structure remains less understood. In this study, we used atomic force microscopy-based single-molecule force spectroscopy (AFM-SMFS) to quantify the Ni-N(His) bond strength in calprotectin, a biologically relevant protein system.

Nerve growth factor (NGF) is critical in regulating the homeostasis of microglial cells. It activates various signaling pathways that mediate the phosphorylation of cAMP response element-binding protein (CREB) at key regulatory sites. The decrease in phosphorylated CREB (p-CREB) expression is linked to neuroinflammatory responses.

Background: Microsurgery demands an intensive period of skill acquisition due to its inherent complexity. The development and implementation of innovative training methods are essential for enhancing microsurgical outcomes. This study aimed to evaluate the impact of a simulation training program on the clinical results of fingertip replantation surgeries.
