Optic nerve formation in mouse involves interactions between netrin-1 at the optic disk and the netrin-1 receptor DCC (deleted in colorectal cancer) expressed on retinal ganglion cell (RGC) axons. Deficiency in either protein causes RGC pathfinding defects at the disk leading to optic nerve hypoplasia (). Here we show that further along the visual pathway, RGC axons in netrin-1- or DCC-deficien...

Mirror movements are involuntary movements on one side of the body that occur simultaneously with intentional movements on the contralateral side. Humans with heterozygous mutations in the axon guidance receptor DCC display such mirror movements, where unilateral stimulation results in inappropriate bilateral motor output. Currently, it is unclear whether mirror movements are caused by incomple...

Fluctuations in the ratio of neutral to charged pions arising due to formation of disoriented chiral condensates (DCC) are discussed using the Φ-measure. The properties of the measure for various cases of DCC and non-DCC are discussed. The effect of detector efficiencies and other experimental factors are presented. Application of the Φ-measure to simulated data, within the context of a simple ...

Dermatology residents perform consults on hospitalized patients, but are often limited in their ability to follow-up with these patients after discharge, leading to inadequate follow-up and understanding of post-discharge transitions of care. In 2013, a discharge continuity clinic (DCC) staffed by the inpatient consult dermatology resident and attending dermatologist was established at one of t...

Controlling the axon growth rate is fundamental when establishing brain connections. Using the thalamocortical system as a model, we previously showed that spontaneous calcium activity influences the growth rate of thalamocortical axons by regulating the transcription of Robo1 through an NF-κB-binding site in its promoter. Robo1 acts as a brake on the growth of thalamocortical axons in vivo. He...

Over recent years the secreted guidance cue, netrin-1, and its receptor, DCC, have been shown to be an essential guidance system driving axon pathfinding within the developing vertebrate central nervous system (CNS). Mice lacking DCC exhibit severe defects in commissural axon extension towards the floor plate demonstrating that the DCC-netrin guidance system is largely responsible for directing...

During development, midline crossing by axons brings into play highly conserved families of receptors and ligands. The interaction between the secreted ligand Netrin-1 and its receptor Deleted in Colorectal Carcinoma (DCC) is thought to control midline attraction of crossing axons. Here, we studied the evolution of this ligand/receptor couple in birds taking advantage of a wealth of newly seque...

BACKGROUND AND OBJECTIVE Several studies have shown the benefits of delayed cord clamping (DCC) in preterm and in healthy newborns at short and long term. Our objective was to evaluate the potentials benefits and risks of DCC in red cell alloimmunization. METHODS This was a comparative before/after study of all living born neonates followed after fetal anemia requiring in utero transfusion. D...

OBJECTIVE To compare the safety and efficacy of transoesophageal atrial pacing (TAP) with an easily swallowed pill electrode and direct current cardioversion (DCC) in patients with atrial flutter that was refractory to appropriate medical treatment. DESIGN Prospective, randomised clinical trial. SETTING Community based United States naval hospital. SUBJECTS Twenty one consecutive patients...

Netrins, a family of laminin-related secreted proteins, have critical roles in axon guidance and cell migration during development. The deleted in colorectal cancer (DCC) protein has been implicated as a netrin-1 receptor component. The expression and function of netrins in adult tissues remain unknown, and direct interaction of netrin-1 with DCC has not been demonstrated. We cloned the human n...
