Recurrent Hypothermia and Autonomic Dysfunction Secondary to Shapiro Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 44‐year‐old man presented with recurrent hypothermia, diaphoresis and hypertension. Extensive investigation for infectious, inflammatory, metabolic and endocrine aetiologies was negative. MR scan of the brain demonstrated no lesions but revealed callosal dysgenesis, consistent with Shapiro syndrome.

Impacts of Human Recreation on Brown Bears (Ursus arctos): A Review and New Management Tool. [PDF]

PLoS ONE, 2016
Increased popularity of recreational activities in natural areas has led to the need to better understand their impacts on wildlife. The majority of research conducted to date has focused on behavioral effects from individual recreations, thus there is a

Are grizzly bear and brown bear the same?

, 2023
Similarities and differences between Grizzly and Brown bears Grizzly bear and brown bear are two of the most iconic bear species that are often confused as being the same. While they do share many similarities, they are actually two different subspecies of the same species, Ursus arctos.

Paternal phylogeographic structure of the brown bear (Ursus arctos) in northeastern Asia and the effect of male-mediated gene flow to insular populations

Zoological Letters, 2017
Background Sex-biased dispersal is widespread among mammals, including the brown bear (Ursus arctos). Previous phylogeographic studies of the brown bear based on maternally inherited mitochondrial DNA have shown intraspecific genetic structuring around ...

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Variable spatiotemporal ungulate behavioral response to predation risk

Ecosphere
Prey must balance resource acquisition with predator avoidance for survival and reproduction. To reduce risk of predation, prey may avoid areas with high predator use, but if they are unable to due to resource acquisition requirements, they may instead ...

Defect Evolution and Mechanical Performance of Fused Filament Fabrication‐Manufactured 17‐4PH Stainless Steel Revealed by X‐Ray Computed Tomography

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...

THE RESULTS OF THE STUDY OF THE BROWN BEAR POPULATION IN THE RUSSIAN PART OF THE PASVIK-INARI TRILATERAL PARK ACCORDING TO DNA ANALYSIS AND DATA FROM CAMERA TRAPS

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017
In framework of an international project of brown bear population monitoring, the bear population size and structure were analyzed on the Russian side of the Pasvik-Inari Trilateral Park (Russia, Norway, Finland) in 2015. The paper presents data gathered
