It is well known that ultraviolet light activates mitogen-activated protein (MAP) kinase by increasing the reactive oxygen species (ROS) in body, enhancing activating 1(AP-1) complexes (c-Jun and c-Fos), matrix metalloproteinases (MMPs) degrading collagen elastin. In this study, we confirmed polyphenolic rich Spatholobus suberectus (SS) stem extracts suppressed (UV)-induced photo-aging. The major active components of SS were identified as gallic acid, catechin, vanillic syringic acid...

Iridium(III) cyclometalates (1c and 2c) in which the two carborane units on 4- or 5-positions of 2-phenylpyridine (ppy) ligands were tethered by an alkylene linker prepared to investigate effect free rotation o-carborane phosphorescence efficiency. In comparison with unlinked complex, tethering o-carboranes ppy (2c) enhanced efficiency over 30-fold polar medium (Φ(PL) = 0.37 vs 0.011 THF), while restricting at 4-positions (1c) negatively affected The different effects restricted likely a...

Abstract Here, we studied the effect of size, shape and surface charge Au nanoparticles (AuNPs) on amyloid beta (Aβ) aggregation a total brain lipid-based supported lipid bilayer (brain SLB), fluid platform that facilitates Aβ-AuNP process. We found larger AuNPs induce large amorphous aggregates SLB, whereas smaller protofibrillar Aβ structures. Positively charged were more strongly attracted to than negatively stronger interactions between resulted in fewer β-sheets random coil also...

Liver fibrosis represents a process of healing and scarring in response to chronic liver injury. Following injury, an acute inflammation takes place resulting moderate cell necrosis extracellular matrix damage. Melittin, the major bioactive component venom honey bee Apis mellifera, is 26-residue amphipathic peptide with well-known cytolytic, antimicrobial proinflammatory properties. However, molecular mechanisms responsible for anti-inflammatory activity melittin have not been elucidated...

The pandemic outbreak of COVID-19 in the year 2020 that drastically changed everyone's life has raised urgent and intense need for development more efficacious antiviral material. This study was designed to develop copper nanoparticles (Cu NPs) as an agent validate activities developed NP. Cu NPs were synthesized using a high energy electron beam, characteristic morphologies evaluated. We found are spherical shape uniformly distributed, with diameter around 100 nm, opposed irregular...

β-site amyloid precursor protein cleaving enzyme 1 (BACE1) plays a role in generating β (Aβ), thus playing major part early the pathogenesis of Alzheimer's disease (AD). BACE1 has emerged as crucial therapeutic target for decreasing Aβ concentration AD brain. To explore natural inhibitors, present study concentrated on isoflavones, including genistein, formononetin, glycitein, daidzein, and puerarin. In this study, vitro anti-AD activities were assessed using inhibition assays, well kinetic...

p57KIP2, a member of the Cip/Kip family enzymes that inhibit several cyclin-dependent kinases, plays role in many biological events including cell proliferation, differentiation, apoptosis, tumorigenesis and developmental changes. The human p57KIP2 gene is located chromosome 11p15.5, region implicated sporadic cancers Beckwith-Wiedemann syndrome. We here report physically interacts with inhibits c-Jun NH2-terminal kinase/stress-activated protein kinase (JNK/SAPK). carboxyl-terminal QT domain...

We sought to determine the effects of activation peroxisome proliferator-activated receptor-gamma (PPAR-gamma) on multilocularization adipocytes in adult white adipose tissue (WAT). Male C57BL/6 normal, db/db, and ob/ob mice were treated with agonists PPAR-gamma, PPAR-alpha, or beta(3)-adrenoceptor for 3 weeks.
