In an attempt to elucidate the mechanism(s) through which the functional adrenal cortex is established, we analyzed immunohistochemically the expression of various markers for the adrenocortical zones, i.e. the zona glomerulosa (zG), the zona fasciculata (zF), and the zona reticularis (zR), as well as markers for the medulla, and further examined the distribution and behavior of DNA-synthesizin...
Morphogenesis is crucial to initiate physiological development and tumor invasion. Here we show that a microRNA controls zonation morphogenesis by targeting hyaluronan receptor CD44. We have developed a novel system to study microRNA functions by generating constructs expressing pre-miRNAs and mature miRNAs. Using this system, we have demonstrated that expression of miR-328 reduced cell adhesio...
The hepatic lobule is divided into three zones along the portal-central vein axis. Hepatocytes within each zone exhibit a distinctive gene expression profile that coordinates their metabolic compartmentalization. The zone-dependent heterogeneity of hepatocytes has been hypothesized to result from the differential degree of exposure to oxygen, nutrition and gut-derived toxins. In addition, the g...
Golestan Province is one of the most vulnerable areas to catastrophic flood events in Iran. The severity this region has grown dramatically during last decades, demanding a major investigation. Accordingly, an authentic map providing detailed information on floods required reduce future disasters. Three ensemble models produced by combination Evaluation Based Distance from Average Solution (EDA...
Early diagenetic modification of magnetic properties is an important process in marine sediments, but temporal and spatial variability of diagenetic processes have rarely been reported for recent coastal sediments. The magnetic properties of sediments from the Ria de Vigo (NW Spain) define a marked three-part zonation with depth. The uppermost zone is magnetically dominated by (titano-)magnetit...
[1] Apatite He/He thermochronometry has the potential to constrain cooling histories for individual samples provided that several presently untested assumptions are valid. Here we simulate the sensitivity of He/He spectra to assumptions regarding geometric model, crystallographic anisotropy, broken grain terminations, parent nuclide zonation, and the accuracy of results obtained from analyses o...
The rapid spread and diversification of outdoor recreation can impact on wildlife in various ways, often leading to the avoidance of disturbed habitats. To mitigate human-wildlife conflicts, spatial zonation schemes can be implemented to separate human activities from key wildlife habitats, e.g., by designating undisturbed wildlife refuges or areas with some level of restriction to human recrea...
The dimensions, shapes and the patterns of natural rivers change according to their dynamic properties. These unavoidable changes cause the rivers imbalance and a new balance will be formed. The around lands will be affected by this dynamic and dangers such as instability of the bed. In this research we used chronological inference method to study Kashkan River morphology. Kashkan river is loc...
Flash floods are the most dangerous kinds of because they combine destructive power a flood with incredible speed. They occur when heavy rainfall exceeds ability ground to absorb it. The main aim this study is generate flash maps using Analytical Hierarchy Process (AHP) and Frequency Ratio (FR) models in river’s floodplain between Jhelum River Chenab rivers. A total eight flood-causative physic...
This paper examines the possible causes of collapse of a primary school in San Giuliano, Italy, in the 2002 Molise earthquake, which killed 27 students and one teacher. It also considers the general sources of seismic vulnerability of school buildings in Italy prior to the introduction of new seismic zonation and new seismic codes in 2003. In addition to incomplete seismic zonation and inadequa...
