The causal consciousness: beta-neurexin promotes neuromediator release via vibrational multidimensional tunneling

Abstract: Epiphenomenalism is shown to be absurd because the development of consciousness must be explainable through natural selection. A detailed neuromolecular basis of the neuromediator release is given and it is stressed on the possible key point where the quantum mind could act, namely presynaptic scaffold protein dynamics and detachment of the calcium sensor v-SNARE synaptotagmin-1. The beta-neurexin molecules are tuned via fast propagating solitons by the quantum coherent microtubule network so that the beta-neurexin molecule thermal vibrations could promote or suppress conformational changes via vibrational multidimensional tunneling, which drives synaptotagmin-1 detachment from the SNARE complex under calcium ion binding. Following the synaptotagmin-1 detachment membrane fusion takes place in SNARE dependent fashion and the presynaptic vesicle spills neuromediator in the synaptic cleft. Thus the quantum transfer of information causally affects the neuromediator release.

Ethnobotanical use of lichens: lichens for food review

Abstract: Traditional uses of lichens for food, food preparation, and chemical constituents of lichens with regards to their nutritional value are briefly reviewed. Reports that indicate significant use of lichens, primarily as food material, are gathered together and presented. The cohesion of data from available studies gives reason to accept that lichens present a great potential source of functional foods. It remains a challenge to explore the effect of lichens in food with respect to the nutrigenomics advent and explore them as a source for nutraceuticals, new foods and food additives.

Virtual clinical trials in 3D and 2D breast imaging with digital phantoms derived from clinical breast CT scans

Abstract: We are developing a platform for virtual (in silico) clinical trials in x-ray breast imaging and dosimetry fully based on Monte Carlo simulations and which adopts patient-like digital phantoms. We report the initial steps and first results of this project. Our collaboration was established for producing a “user-friendly” computational platform which reproduces both 2D (full-fields digital mammography) and 3D (digital breast tomosynthesis, CT dedicated to the breast) breast imaging examinations for technique optimization and for developing protocols and computed aided diagnostic applications. Dose optimization strategies and technique performance comparisons will be explored. A dataset of anatomically realistic, 2D and 3D digital breast phantoms have been produced by means of voxel classification and digital compression of clinical breast CT scans acquired at UC Davis. Monte Carlo simulations, based on the Geant4 toolkit, have been developed for insilico FFDM, DBT and BCT examinations.
