2-Arachidonyl glycerol (2-AG) is an endogenous arachidonic acid derivative that binds cannabinoid receptors CB1 and CB2 and is hence termed an endocannabinoid. 2-AG also modulates a variety of immunological responses, including expression of the autocrine/paracrine T cell growth factor interleukin (IL)-2. The objective of the present studies was to determine the mechanism responsible for IL-2 s...

The prevalent hardening phase forming in an Al-Cu-Mg-Ag alloy after peak-aging at 150 and 190 °C has been investigated using transmission electron microscopy methods. precipitate atomic structure was determined. It is a hybrid (HP) with plate morphology on {111}Al planes, consisting of orthorhombic hexagonal structural fragments. Density functional theory calculations suggest that the hybridiza...

Abstract Al-Cu-Ag-Fe-Mg-Zr-Er alloy with different content of Er addition was prepared by using metallurgy processing. The Al-4.5%Cu-0.5%Ag-0.35%Fe-0.38%Mg-0.1%Zr-xEr phase and its refinement mechanism were studied SEM. Tensile fatigue tests performed for the in state deformation treatment condition. microstructural observations reveal that 0.2% rare earth can effectively refine grain structure...

Distribution and behavior of many trace elements in the aquatic environment has been well characterized, but little is known about silver (Ag) concentrations in coastal waters, even though this element ranks among the most toxic to marine invertebrates (Calabrese et al., 1977 ; Fisher and Hook, 1997 ; Webb and Wood, 1998). Studies conducted by Flegal et al. (1995), River-Duarte et al. (1999), a...

Moreover, to further boost the device effi ciency, a resonant optical cavity can be created between the transparent thin Ag fi lm and an opaque back contact metal electrode, thus trapping light inside the active layer and enhancing its light absorption. [ 22 ] However, Ag follows 3D growth mode: during deposition, Ag atoms fi rst agglomerate into isolated islands, and as the deposition continue...

introduction one of the best methods in the diagnosis and control of breast cancer is mammography. the importance of mammography is directly related to its value in the detection of breast cancer in the early stages, which leads to a more effective treatment. the purpose of this article was to calculate the x-ray spectrum in a mammography system with monte carlo codes, including mcnpx and mcnp5...

Berg et al. (Clin Genet 1986;30:515-520) have reported that an Xba I DNA polymorphic site in exon 26 of the apolipoprotein (apo) B gene is associated both with the Ag(x/y) immunochemical polymorphism and with elevated serum lipoprotein levels. Ma et al. (Arteriosclerosis 1987;7:301-305) have reported that the same Xba I polymorphism is associated with a different immunochemical polymorphism, Ag...

A postsynthetic modification method was used to prepare thiol-functionalized metal-organic frameworks (MOFs) by the amidation of mercaptoacetic acid with the amine group, which is present in the frameworks of NH2-MIL-53(Al). By doing this, the thiol group has been successfully grafted on the MOF, which perfectly combined the highly developed pore structures of the MOF with the strong coordinati...

In order to assist in planing the search of supernova (SN) in the late time afterglow of the gamma ray burst (GRB) 011121 we use the Cannonball Model of GRBs and the early time observations of its afterglow (AG) in the R band to predict its late time decline and intrinsic spectrum.tected and localized by BeppoSAX (Piro 2001a,b) and IPN (Hurley et al. 2001). Its optical afterglow was first detec...
