Zero energy bound states in tunneling conductance spectra at the interface of an s-wave superconductor and a topological insulator in NbN-$Bi_2Se_3$-Au thin film junctions

, 2012
Measurements of conductance spectra in a superconductor - topological insulator - normal metal thin film junctions of NbN-$\rm Bi_2Se_3$-Au are reported. Junctions with ex-situ and in-situ prepared $\rm NbN-Bi_2Se_3$ interfaces were studied.

Death of Neurons following Injury Requires Conductive Neuronal Gap Junction Channels but Not a Specific Connexin.

PLoS ONE, 2015
Pharmacological blockade or genetic knockout of neuronal connexin 36 (Cx36)-containing gap junctions reduces neuronal death caused by ischemia, traumatic brain injury and NMDA receptor (NMDAR)-mediated excitotoxicity.

Temperature and junction-type dependency of Andreev reflection in MgB2

, 2001
We studied the voltage and temperature dependency of the dynamic conductance of normal metal-MgB2 junctions obtained either with the point-contact technique (with Au and Pt tips) or by making Ag-paint spots on the surface of high-quality single-crystal ...

MgB2 tunnel junctions and 19 K low-noise dc superconducting quantum interference devices [PDF]

, 2001
Point contact junctions made from two pieces of MgB2 can be adjusted to exhibit either superconductor-insulator-superconductor (SIS) or superconductor-normal metal-superconductor (SNS) current-voltage characteristics.

Gap Junctions in Development [PDF]

American Zoologist, 1986
The concept of a multicellular organism as an assemblage of cells that work together harmoniously for the good of the whole organism is well established. Over the past 15 years, however, it has become increasingly clear that the individual cells of multicellular animals are not as self-sufficient and independent of each other as once had been believed.

Interactions between innexins UNC-7 and UNC-9 mediate electrical synapse specificity in the Caenorhabditis elegans locomotory nervous system

Neural Development, 2009
Background Approximately 10% of Caenorhabditis elegans nervous system synapses are electrical, that is, gap junctions composed of innexins. The locomotory nervous system consists of several pairs of interneurons and three major classes of motor neurons ...

Vitamin D3 regulates the formation and degradation of gap junctions in androgen-responsive human prostate cancer cells.

PLoS ONE, 2014
1α-25(OH)2 vitamin D3 (1-25D), an active hormonal form of Vitamin D3, is a well-known chemopreventive and pro-differentiating agent. It has been shown to inhibit the growth of several prostate cancer cell lines.

Neural progenitor cells isolated from the subventricular zone present hemichannel activity and form functional gap junctions with glial cells

Frontiers in Cellular Neuroscience, 2015
The postnatal subventricular zone lining the walls of the lateral ventricles contains neural progenitor cells (NPCs) that generate new olfactory bulb interneurons.

Cancer Connectors: Connexins, Gap Junctions, and Communication

Frontiers in Oncology, 2018
Despite concerted clinical and research efforts, cancer is a leading cause of death worldwide. Surgery, radiation, and chemotherapy have remained the most common standard-of-care strategies against cancer for decades.

The components of an electrical synapse as revealed by expansion microscopy of a single synaptic contact

eLife
Most nervous systems combine both transmitter-mediated and direct cell–cell communication, known as ‘chemical’ and ‘electrical’ synapses, respectively. Chemical synapses can be identified by their multiple structural components.
