Spatial memory processing requires functional interaction between the hippocampus and the medial entorhinal cortex (MEC). The grid cells of the MEC are most abundant in layer II and rely on a complex network of local inhibitory interneurons to generate spatial firing properties. Stress can cause spatial memory deficits in males, but the specific underlying mechanisms affecting the known memory ...

Eddy current testing can be used to interrogate steels but it is hampered by the lift-off distance of sensor. Previously, point intersection (LOI) feature has been found for pulsed eddy (PEC) testing. In this paper, a invariant inductance (LII) proposed multi-frequency (MEC) testing, which merely targets ferromagnetic steels. That is, at certain working frequency, measured signal nearly immune ...

Light Detection and Ranging (LiDAR) has been used to extract surface information as it can acquire highly accurate object shape characteristics using geo-registered 3D-points. Therefore, LiDAR can be used to effectively measure tree parameters in forested areas. In this research, we estimated the LAI (Leaf Area Index) for Pinus koraiensis, Larix leptolepis and Quercus spp. using LiDAR data. For...

BACKGROUND Numerous strategies have been proposed to decrease the treatment time a patient requires in orthodontic treatment. Recently, a number of device-accelerated therapies have emerged in orthodontics. Photobiomodulation is an emerging area of science that has clinical applications in a number of human biological processes. The aim of this study was to determine if photobiomodulation reduc...

In this study, the association between genotypic and selected phenotypic characteristics was examined in a collection of Canadian Escherichia coli O157:H7 strains isolated from humans and cattle in the provinces of Alberta, Ontario, Saskatchewan, and Quebec. In a subset of 69 strains selected on the basis of specific phage types (PTs), a strong correlation between the lineage-specific polymorph...

BACKGROUND Nasal fractures have a tendency of resulting in structural or functional complications, and the results can vary according to the type of nasal bone fracture. The aim of this study was to evaluate the objective postoperative results according to the type of nasal bone fractures. METHODS We reviewed 313 patients who had a closed reduction of nasal bone fracture. The classification o...

We have previously shown that Xenopus oocytes, eggs, and early embryos contain lamins LII and LIII, and that portions of each are associated with distinct egg vesicle populations. We now report that a lamin similar or identical to the B-type lamin LI is also present in oocyte nuclei and in egg extracts. We have quantitated the three B-type lamins per oocyte nucleus, and have calculated relative...

The cooling rate of soot particles after laser induced incandescence (LII) is thought to provide an estimate of the size of nanoparticles (NPs) in the engine exhaust. It is shown that cooling rate is not applicable to NPs, and instead is only a measure of the size of micron-sized particles. The problem is that the conservation of absorbed laser photon energy in NPs is subject to quantum electro...

Lii-Nao countertransport was measured in red blood cells of 58 normotensive subjects (27 females and 31 males), 60 patients with essential hypertension (26 females and 34 males), and in 28 with secondary hypertension (19 females and 9 males). The mean values (+/- SEM) expressed as mmol Li (1 red cells X hr)-1 were 0.18 +/- 0.02 (females) and 0.20 +/- 0.01 (males) in the control group, 0.34 +/- ...
