The Neuro Image Quiz, Answers T.P. Thomas P. Naidich Thomas P. Naidich, MD, Division of Neuroimaging, Children’s Memorial Hospital, 2300 Children’s Plaza, Chicago, IL 60614 (USA) These images demonstrate a well-circumscribed lobu-lated erosion of the anterior parietal bone, situated just posterior to the coronal suture. In this case the zone of transition from obviously normal bone to obviously...

Abstract Regarding disadvantages of fossil fuels, renewables like geothermals can be an eco-friendly source energy. In Iran, the availability fuels and poor policies surrounding subsidies (ranked as first in giving subsidies) caused high energy consumption (1.75 times higher than global average). Energy is mainly provided by that leads to CO 2 emission. This study evaluates trend potentials mor...

Mutations in human CEP290 cause cilia-related disorders that range in severity from isolated blindness to perinatal lethality. Here, we describe a Chlamydomonas reinhardtii mutant in which most of the CEP290 gene is deleted. Immunoelectron microscopy indicated that CEP290 is located in the flagellar transition zone in close association with the prominent microtubule-membrane links there. Ultras...

Roots are very sensitive to hypoxia and adapt effectively to a reduced availability of oxygen in the soil. However, the site of the root where oxygen availability is sensed and how roots acclimate to hypoxia remain unclear. In this study, we found that the root apex transition zone plays central roles in both sensing and adapting to root hypoxia. The exposure of cells of the root apex to hypoxi...

Root elongation requires cell divisions in the meristematic zone and cell elongation in the elongation zone. The boundary between dividing and elongating cells is called the transition zone. In the meristem zone, initial cells are continuously dividing, but on the basal side of the meristem cells exit the meristem through the transition zone and enter in the elongation zone, where they stop div...

[1] The ARM Shortwave Spectrometer (SWS) measures zenith radiance at 418 wavelengths between 350 and 2170 nm. Because of its 1-sec sampling resolution, the SWS provides a unique capability to study the transition zone between cloudy and clear sky areas. A spectral invariant behavior is found between ratios of zenith radiance spectra during the transition from cloudy to cloud-free. This behavior...
