Location is everything: The hemodynamic effects of REBOA in Zone 1 versus Zone 3 of the aorta.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging technology to augment proximal blood pressure during the resuscitation of patients with noncompressible torso hemorrhage. Currently, placement choice, supraceliac (Zone 1) versus infrarenal (Zone 3) aorta, depends on injury patterns, but remains a highly debated topic. We sought to compare the proximal hemodynamic support provided by Zone 1 versus Zone 3 REBOA placement and the degree of hemodynamic instability upon reperfusion...

More are better, but the details matter: combinations of multiple Fresnel zone plates for improved resolution and efficiency in X-ray microscopy.

Fresnel zone plates used for X-ray nanofocusing face high-aspect-ratio nanofabrication challenges in combining narrow transverse features (for high spatial resolution) along with extended optical modulation along the X-ray beam direction (to improve efficiency). The stacking of multiple Fresnel zone plates along the beam direction has already been shown to offer improved characteristics of resolution and efficiency when compared with thin single zone plates. Using multislice wave propagation simulation meth...

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...

Assessment of Water Resources Sustainability in Mainland China in Terms of Water Intensity and Efficiency.

Investigation into water resources sustainability (WRS) is vital for a regional sustainable development strategy. This paper aimed to quantitatively evaluate the WRS in mainland China using a three-layer indicator system. Three important factors significantly affecting WRS are: water resources quantity (WRQ), water intensity (WI) and water efficiency (WE). Assessment of the three indicators was carried out in 356 cities where each indicator was graded from "very low" to "very high" according to the value ma...

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...

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...

The utility of high-sensitivity C-reactive protein levels in patients with moderate coronary lesions and gray-zone fractional flow reserve.

It remains controversial whether patients with fractional flow reserve (FFR) values of 0.75-0.80 (gray-zone) should be treated with percutaneous coronary intervention (PCI). This study aimed to evaluate the prediction of high-sensitivity C-reactive protein (hs-CRP) levels to guide treatment selection in gray-zone patients.
