Effects of propofol combined with lidocaine on hemodynamics, serum adrenocorticotropic hormone, interleukin-6, and cortisol in children.

Background: Children are a unique patient population. Anesthesia for pediatric abdominal surgery has long been achieved mainly with intravenous amiodarone and propofol alone or combined with other anesthetics. The incidence of complications and postoperative adverse reactions is relatively high owing to the imperfect development of various protocols for children.

Synthesis, characterization and preliminary biological evaluation of chrysin amino acid derivatives that induce apoptosis and EGFR downregulation.

Chrysin amino acid derivatives were synthesized to evaluate for their antiproliferative activities. Among them, -(7-((5-hydroxy-4-oxo-2-phenyl-4H-chromen-7-yl)oxy)valeryl)-L-leucine () displayed the most remarkable inhibitory activities against MCF-7 cells with IC values of 16.6 μM.

Effects of PTEN inhibition on regulation of tau phosphorylation in an okadaic acid-induced neurodegeneration model.

One of pathological hallmarks of Alzheimer's disease (AD) is neurofibrillary tangles (NFTs) consisting of abnormally hyperphosphorylated tau. The molecular mechanisms underlying the regulation of tau hyperphosphorylation remain largely unclear. The phosphoinositide 3-kinase (PI3K)/Akt pathway has been implicated in the pathogenesis of AD, however, potential functions and role of tumor suppressor phosphatase and tensin homologue deleted on chromosome 10 (PTEN) in AD pathogenesis have not been fully explored.

Electrophoretic deposition of silicon substituted hydroxyapatite coatings from n-butanol-chloroform mixture.

Silicon Substituted Hydroxyapatite (Si-HA) coatings were prepared on titanium substrates by electrophoretic deposition (EPD). The stability of Si-HA suspension in n-butanol and chloroform mixture has been studied by electricity conductivity and sedimentation test. The microstructure, shear strength and bioactivity in vitro has been tested.
