2020-09-15

However, the Moon is not the only possible source for space resources. Asteroids, in particular near-Earth asteroids (NEAs), can provide an alternative source for propellant and other materials, sometimes at lower cost. There are an expected 4000 NEAs that require less propellant (delta-V) per trip

To avoid the difficulty of the nonsmooth constraints, a sequence of smooth problems by using smoothing functions have been progressively approximated this nonsmooth problem. To date, there have been many smoothing functions, such as perturbed Fischer–Burmeister (FB), Chen–Harker–Kanzow–Smale (CHKS),

Conclusion In conclusion, our findings do not suggest that HT is an important determinant of future AD risk and are in line with a recent Cochrane review stating that HT is not indicated for preventing dementia or cognitive decline in postmenopausal women [13]. Contributors Conflict of inte

More and more studies are focused on the function role of EPAC1 in cancer proliferation, apoptosis and migration. Recently, it was reported that the EPAC-ERK and AKT signaling pathways promote the B cell antigen receptor (BCR) mediated growth arrest and apoptosis in the B lymphoma cell line WEHI-231

Only a few studies have examined the effect of prostanoids on cardiac fibroblasts. Therefore, this study examines the effect of PGE2 on cardiac fibroblast proliferation and tests the hypothesis that PGE2 causes cardiac fibroblast proliferation via alterations of microcystin lr receptor regulatory m

Mammalian cells contain significant amounts of a relatively lesser known enzyme that shows marked specifity for ether lipids containing AA and other 20–22 carbon fatty acids. This enzyme is called CoA-independent transacylase (CoA-IT), and transfers polyunsaturated moieties of 20–22 carbons, typical

Omar Farha and coworkers have recently successfully employed metal-organic frameworks (MOFs) to tackle these limitations while retaining the essential characteristics of an immobilization material. MOFs consist of metal ions, or small clusters thereof, coordinated with organic ligands. MOFs are high

Several recent reviews have appeared covering different aspects of the sPLA2 family of enzymes, including sPLA2-V, and the interested reader is kindly directed to these for specific details [34,[135], [136], [137]]. It is important to remark here, however, that recent studies on sPLA2-V suggest that

Conclusion In this study, we investigated functional alterations of ECs following exposure to mechanical and/or physicochemical stimuli. Specifically, hypoxia induced phosphorylation with significant increases after 30 min and the maximum increase was after 180 min. Our data show that a combinati

Ubiquitination can occur on a single (monoubiquitination) or several (multiubiquitination) lysine residues, or the same lysine residue can be subjected to several rounds of Ub conjugation (polyubiquitination). Ub bonds within polyUb chains are formed through 1 of 7 lysine residues in Ub, and the typ

Main Text Post-translational modifications by ubiquitin (Ub) and ubiquitin-like proteins (Ubl) regulate a diverse array of cellular and physiological processes including protein degradation, localization, and activation. While ubiquitination has primary responsibility for targeting substrates for p

Given the widespread occurrence of oncogene-induced RS and the increasing clinical interest in small molecule inhibitors that further exacerbate RS in human cancers (such as ATR inhibitors), our findings point to a protective role for RAD52 in the maintenance of cancer cell viability. As such, RAD52

In the present study, we implemented the dendritic RCA-induced formation of amplifying DNAzyme catalytic labels strategy for sensitive and accurate assay of MTase activity and the detection of DNA methylation. In comparison with the traditional RCA process, the proposed strategy achieved high amplif
