    “…Moreover, expression of chemokine CCL2, MCP-1 and its receptor CCR2, which play an important role in macrophage chemotaxis, were reduced in WAT of PDE3B(−/−)mice. In addition, atherosclerotic plaque formation was significantly reduced in the aorta of apoE(−/−)/PDE3B(−/−)and LDL-R(−/−)/PDE3B(−/−)mice compared to apoE(−/−)and LDL-R(−/−)mice, respectively. …”

    “…Although they are based on the nominally simple cubic perovskite structure, these compounds are in fact very complex. For example, in (CH(3)NH(3))PbI(3) the dynamics and ensuing structural fluctuations associated with the (CH(3)NH(3))(+) ions and the interplay with the electronic properties are still not fully understood, despite extensive study. …”

    “…Autophagy is a conserved eukaryotic pathway critical for cellular adaptation to changes in nutrition levels and stress. The class III phosphatidylinositol (PI)3-kinase complexes I and II (PI3KC3-C1 and -C2) are essential for autophagosome initiation and maturation, respectively, from highly curved vesicles. …”

    “…Excellent conversion efficiencies of over 20 % and facile cell production have placed hybrid perovskites at the forefront of novel solar cell materials, with CH(3)NH(3)PbI(3) being an archetypal compound. The question why CH(3)NH(3)PbI(3) has such extraordinary characteristics, particularly a very efficient power conversion from absorbed light to electrical power, is hotly debated, with ferroelectricity being a promising candidate. …”

    “…In the present work, arylethynes were studied as new C-nucleophiles in the asymmetric Mannich addition reactions with (S)-N-tert-butylsulfinyl-3,3,3-trifluoroacetaldimine. The reactions were conducted under operationally convenient conditions affording the corresponding Mannich adducts with up to 87% yield and 70:30 diastereoselectivity. …”

    “…Hydrolysis of glucobrassicin by plant or bacterial myrosinase produces multiple indoles predominantly indole-3-carbinol (I3C). I3C and its major in vivo product, 3,3'-diindolylmethane (DIM), are effective cancer chemopreventive agents in pre-clinical models and show promise in clinical trials. …”
