Slow shift of dead zone after an abrupt shift of the light-dark cycle.

The suprachiasmatic nucleus (SCN) is the center of the mammalian circadian system. Environmental photic signals shifts the phase of the circadian rhythm in the SCN except during the dead zone, when the photic signal is gated somewhere on the way from the retina to the neurons in the SCN. Here we examined the phase of the dead zone after an abrupt delay of the LD cycles for several days by observing the mc-Fos induction in the SCN by light pulses. After an abrupt shift of the LD cycles, the dead zone showed ...

Paradigm shift from "Compartment" to "Zone" in the understanding of organelles.

Organelles are intracellular compartments that are delineated by lipid bilayers and play specific roles in regulating various cellular events. Organelle dysfunction contributes to the pathological mechanisms of various diseases. The development and prevalence of super-resolved fluorescence microscopy have enabled the characterization of various functional regions and organellar dynamics by a number of cell biologists. These local functional organelle regions are named "zones", and three review articles in t...

Intraoperative neurophysiological monitoring of the bulbocavernosus reflex during surgery for conus spinal lipoma: what are the warning criteria?

OBJECTIVEDespite the surge in the intraoperative use of the bulbocavernosus reflex (BCR) during lumbosacral surgeries, there are as yet no widely accepted BCR warning criteria for use with intraoperative neurophysiological monitoring (IONM). The author's aim was to find clinically acceptable warning criteria for use in IONM of the BCR.METHODSRecords of IONM of the BCR in 164 operations in 163 patients (median age 5 months) with a conus spinal lipoma who underwent surgery between August 2002 and May 2016 wer...

Prox1 mRNA expression in the medial cortex of the turtle (Pseudemys scripta elegans).

The medial cortex of the cerebrum in reptiles is thought to be homologous to the mammalian dentate gyrus, based on cytoarchitectures, fiber connections, and neurochemical profiles. To support this hypothesis, we examined the mRNA expression of vesicular glutamate transporter 1 (vGluT1), a glutamatergic gene marker, and Prox1, a selective gene marker for granule cells of the dentate gyrus, in the turtle medial cortex (zone 2). Reverse transcription-polymerase chain reaction revealed the presence of both mRNA...

Characteristics of organic nitrogen fractions in sediments of the water level fluctuation zone in the tributary of the Yangtze River.

The contents of different organic nitrogen (N) fractions, their contributions to total N (TN) and the relationship between their mineralizable N (MN) and different organic N fractions in sediments of the water level fluctuation (WLF) zone were investigated. The contents of TN, acid hydrolyzable N (AHN), and nonhydrolyzable N (NHN) decreased in sediments from the lower altitudes of the WLF zone. The AHN and NHN accounted for 70.56 to 82.89% and 17.11 to 29.44% of TN, respectively. The AHN was the main organi...

Transient analytical solution for one-dimensional transport of organic contaminants through GM/GCL/SL composite liner.

Analytical solution for transport of organic contaminants through composite liner consisting of a geomembrane (GM), a geosynthetic clay liner (GCL), and a soil liner (SL) with finite thickness is presented. The transient diffusion-advection processes in the whole composite liner and adsorption in GCL and SL can be described by the present method. The method is successfully verified against analytical solution to a coupling transient diffusion-advection problem in double-layer porous media. The rationality o...

Interictal stereotactic-EEG functional connectivity in refractory focal epilepsies.

Drug-refractory focal epilepsies are network diseases associated with functional connectivity alterations both during ictal and interictal periods. A large majority of studies on the interictal/resting state have focused on functional MRI-based functional connectivity. Few studies have used electrophysiology, despite its high temporal capacities. In particular, stereotactic-EEG is highly suitable to study functional connectivity because it permits direct intracranial electrophysiological recordings with rel...

A mechanism of T cell dependent selection of antigen engaged Germinal Center B cells.

A model of B cell affinity selection is proposed, and an explanation of peripheral tolerance mechanisms through antibody repertoire editing is presented. We show that affinity discrimination between B cells is driven by a competition between obtaining T cell help and removal of B cells from the light zone, either through apoptosis or by a return to the dark zone of germinal centers. We demonstrate that this mechanism also allows for the negative selection of self reactive B cells and maintenance of B cell t...

Testing an hypothesis of hybrid zone movement for toads in France.

Hybrid zone movement may result in substantial unidirectional introgression of selectively neutral material from the local to the advancing species, leaving a genetic footprint. This genetic footprint is represented by a trail of asymmetric tails and displaced cline centres in the wake of the moving hybrid zone. A peak of admixture linkage disequilibrium is predicted to exist ahead of the centre of the moving hybrid zone. We test these predictions of the movement hypothesis in a hybrid zone between common (...

Key features of the nephrogenic zone in the fetal human kidney-hardly known but relevant for the detection of first traces impairing nephrogenesis.

In healthy newborn babies, nephrogenesis proceeds unnoticed until birth. With start of the perinatal period, morphogenetic activity in the renal outer cortex consisting of an inner maturation zone and an outer nephrogenic zone is downregulated by unknown signals. One of the results is that the entire nephrogenic zone as well as the contained progenitor cells and niches disintegrate. In contrast, a too early inactivation of the nephrogenic zone takes place in the kidneys of preterm and low birth weight babie...
