To determine the efficacy of a novel and safer (for gastrointestinal tract) aspirin (aspirin-PC) in preclinical models of ovarian cancer, in vitro dose-response studies were performed to compare the growth-inhibitory effect of aspirin-PC versus aspirin on three human (A2780, SKOV3ip1, and HeyA8) and a mouse (ID8) ovarian cancer cell line over an 8-day culture period. In the in vivo studies, the...
Vascular endothelial growth factor A (VEGF-A) is considered one of the most important factors in tumor angiogenesis, and consequently, a number of therapeutics have been developed to inhibit VEGF signaling. Therapeutic strategies to target brain malignancies, both primary brain tumors, particularly in pediatric patients, and metastases, are lacking, but targeting angiogenesis may be a promising...
Coordination of two sets of movements, protraction-retraction versus opening-closing, of the feeding apparatus (the radula) in ingestive and egestive motor programs of Aplysia resembles vertebrate intralimb coordination in that the relative timing of the two sets of movements differs in the two motor programs. In both ingestion and egestion, radula protraction and retraction alternate, whereas ...
Fossil fuels such as diesel are being gradually replaced by biodiesel, a renewable energy source, cheaper and less polluting. However, little is known about the toxic effects of this new energy source on aquatic organisms. Thus, we evaluated biochemical biomarkers related to oxidative stress in Nile tilapia (Oreochromis niloticus) after two and seven exposure days to diesel and pure biodiesel (...
Recently, it has been shown that the activation of the Drosophila EGF receptor (DER) by its natural ligand Spitz is inhibited by Argos [Schweitzer, R., et al. (1995) Nature 376, 699-702]. Argos and Spitz both have an EGF-like domain which in the case of Argos differs from that of Spitz and other EGF receptor agonists in that it has an extended B-loop of 20 amino acids instead of 10 amino acids ...
The electronic structures of MnGe were studied by density functional theory. B20 crystal structure plays an important role to make properties this compound. electromagnetic characteristics compared with those MnSi due same structure. value magnetic moment between two compounds has a large difference, which comes from the states. shows half-metal characteristics. It $2.0_{\mu B}$ is 5 times that...
The electrical and structural properties of Co40Fe40B20 (CoFeB) alloy are tunable with thermal annealing. This is key in the optimization CoFeB-based spintronic devices, where advantageously low magnetic coercivity, high spin polarization, controllable magnetocrystalline anisotropy utilised. So far, there has been no report on superconducting devices based CoFeB. Here, we Nb/CoFeB/Nb Josephson ...
The spin-1 chiral semimetal is a state of quantum matter hosting unconventional fermions that extend beyond the common Dirac and Weyl fermions. B20-type CoSi prototypal material accommodates such an exotic quasiparticle. To date, spin-transport properties in semimetals have not been thoroughly explored. In this work, we fabricated B20-CoSi thin films on sapphire $c$-plane substrates by magnetro...
