    The cerebral blood flow response to neuroactivation is reduced in cognitively normal men with β-amyloid accumulation by Mark Bitsch Vestergaard, Aftab Bakhtiari, Merete Osler, Erik Lykke Mortensen, Ulrich Lindberg, Ian Law, Martin Lauritzen, Krisztina Benedek, Henrik Bo Wiberg Larsson

    Published 2025-01-01
    “…Conclusion We found a correlation between high PiB SUVr and reduced CBF response to neuronal activation, indicating a link between Aβ accumulation and impaired cerebrovascular function. The impairment was not associated with cortical thinning or hypometabolism, suggesting that Aβ accumulation affecting brain vessel function could be a very early pathology leading to neurodegenerative disease.…”

    The role of B12 deficiency and methionine synthase in methionine-dependent cancer cells by Mohamed M. A. El Husseiny, Roland Nilsson

    Published 2025-07-01
    “…Abstract Background Human cells can synthesize methionine from homocysteine and folate-coupled methyl groups via the B12-dependent enzyme methionine synthase (MTR). Yet, it has been known for decades that cancer cells fail to grow when methionine is replaced by homocysteine, a phenomenon known as methionine dependence. …”

    Photocatalytic degradation of natural organic matter: Kinetic considerations and light intensity dependence by Ceyda Senem Uyguner, Miray Bekbolet

    Published 2004-01-01
    “…The pseudo first order kinetic model and Langmuir-Hinshelwood (L-H) rate equation in modified forms were used to compare the photocatalytic activities of TiO2 materials as a function of light intensity. Under constant irradiation conditions, the pseudo first order reaction rates as well as L-H rates were found to be decreasing in the following trend; Degussa P-25, Millennium PC-500 and Millennium PC-100. …”

    Dopamine increases protein synthesis in hippocampal neurons enabling dopamine-dependent LTP by Tanja Fuchsberger, Imogen Stockwell, Matty Woods, Zuzanna Brzosko, Ingo H Greger, Ole Paulsen

    Published 2025-03-01
    “…The reward and novelty-related neuromodulator dopamine plays an important role in hippocampal long-term memory, which is thought to involve protein-synthesis-dependent synaptic plasticity. However, the direct effects of dopamine on protein synthesis, and the functional implications of newly synthesised proteins for synaptic plasticity, have not yet been investigated. …”
