Robust symmetric multiplication for programmable analog VLSI array processing [PDF]
, 2006 This paper presents an electrically programmable analog multiplier. The circuit performs the multiplication between an input variable and an electrically selectable scaling factor. The multiplier is divided in several blocks: a linearized transconductor,

Biochemistry and Molecular Biology Education, 2009 AbstractDiverse biological data may be used to create illustrations of molecules in their cellular context. I describe the scientific results that support a recent textbook illustration of the neuromuscular synapse. The image magnifies a portion of the synapse at one million times, showing the location and the form of individual macromolecules. Results

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT C‐truncating variants in the charged multivesicular body protein 2B (CHMP2B) gene are a rare cause of frontotemporal lobar degeneration (FTLD), previously identified only in Denmark, Belgium, and China. We report a novel CHMP2B splice‐site variant (c.35‐1G>A) associated with familial FTLD in Spain. The cases were two monozygotic male twins who

In vitro Assessment of Immunological Synapse Formation by Flow Cytometry
Bio-Protocol, 2016 In adaptive immune system, formation of immunological synapse between T cells and antigen presenting cells (dendritic cells, B cells, and macrophages) or target cells (tumor cells and viral-infected cells) is critical for the execution of T cell immune ...

Energy efficiency of information transmission by electrically coupled neurons
, 2012 The generation of spikes by neurons is energetically a costly process. This paper studies the consumption of energy and the information entropy in the signalling activity of a model neuron both when it is supposed isolated and when it is coupled to ...

Microglia contact induces synapse formation in developing somatosensory cortex
Nature Communications, 2016 Microglia are the immune cells of the central nervous system that play important roles in brain pathologies. Microglia also help shape neuronal circuits during development, via phagocytosing weak synapses and regulating neurogenesis.

NMDAR‐Antibody Encephalitis Diagnosed With Primary Central Nervous System Lymphoma: A Case Series
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT N‐methyl‐D‐aspartate receptor‐antibody encephalitis (NMDAR encephalitis) is one of the most common forms of autoimmune encephalitis, with a paraneoplastic relationship described in approximately 38%. Primary central nervous system lymphoma (PCNSL) is a rare hematologic malignancy that is not often considered as the underlying neoplasm in this ...
