  Introduction Addiction to opioids such as morphine is a chronic disorder that affects the mesocorticolimbic dopaminergic pathway in the brain. Activation of the pathway ultimately leads to dopamine release in the nucleus accumbens (NAc) (Di Chiara et al., 1998) and stimulation of dopamine recepto

The OBD of DNA ligases adopts at least two distinct orientations during the catalytic cycle. In the adenylation step,

  Although elevated production of cysLTs is characteristic of rhinosinusitis of diverse etiology, patients with aspirin-sensitive rhinosinusitis show even higher levels of cysLTs in the nasal mucosa, which are further enhanced by aspirin challenge., Elevated production of cysLTs in these patients may

  Stressful life events are modulators of mood and can trigger a variety of destructive behavior, including drug abuse and relapse in addicts (Association, 2013; Chen et al., 2012; Sinha, 2009). Likewise, drug-associated stimuli evoke a negative affective state in abstinent drug users. Compelling evid

  Many authors have described the existence of correlation between viability and moisture content and therefore, water availability. Sabuquillo et al.

  Asteroids can provide an abundant supply of other resources, such as carbon, nitrogen, or calcium compounds, but will only be useful once the space economy is sufficiently developed to provide economically interesting uses for them. Others, such as titanium or aluminium, also exist in asteroids, but

  The previously described endogenous patterns of IGF-1-induced kinase signaling, and resulting interaction between MAPK and PI3K, differ across neuronal sub-types. In R28 retinal neuron-like cells, IGF-1 treatment elicits prolonged activation (at least 80 min) of both PI3K and MAPK (Kong et al., 2016

  Our results demonstrated that ET-1, a Wnt ligand, stimulated the Wnt/β-catenin signaling pathway. First, ET-1/ETRA binds to Frizzled family cell-surface receptors, resulting in the activation of Dvl1, a Dishevelled (DSH) family protein. Next, activated DSH inhibits the Axin, GSK-3β, and APC protein

  Most remarkably, an essentially identical collagen-binding mode to DDR2 is employed by SPARC, an α-helical matricellular protein unrelated to DDR2 that also recognizes the GVMGFO motif in collagen (Giudici et al., 2008, Hohenester et al., 2008). The convergence of binding mechanisms suggests that th

  Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In
