Analysis of energy expenditure and behavioral characteristics in different mouse strains under normal and disease conditions

Animal Models and Experimental Medicine, EarlyView.
Mouse metabolic and behavioral phenotypes are tightly linked to strain, age and disease state, with distinct dysregulation in each disease model, underscoring the need for standardized preclinical experimental conditions. Abstract Background Metabolic and behavioral traits in mice exhibit substantial variability across strains, ages, and disease states,

Diabetes and the Metabolic Syndrome as Drivers of Neurodegeneration: Convergent Mechanisms Linking Peripheral Neuropathy and Dementia

Annals of Neurology, EarlyView.
The metabolic syndrome, a state of progressive metabolic dysfunction, injures the peripheral and central nervous systems, promoting peripheral neuropathy (PN) and cognitive impairment (CI), respectively. We posit PN and CI are connected in the metabolic syndrome framework, built on the premise that neurons, whether in the peripheral or central nervous ...

EUV spectroscopy of stellar coronae

AIP Conference Proceedings, 1996
The EUV spectral region contains a wealth of plasma diagnostics for stellar coronae (Te∼5×105 to 2×107 K). Of particular importance for understanding coronal structure are the observable emission lines of highly ionized iron (Fe VIII—XXIV), which allow the determination of electron temperatures (and the detailed temperature distributions) and electron ...

Some Exosat Results on Stellar Coronae

1988
The EXOSAT Observatory has contributed substantially to our understanding of X-ray emission from stellar coronae for both single stars and close binaries. We present the highlights of EXOSAT results on stellar coronae with emphasis on the following topics: a) the temperature structure of coronae, as derived from low- and medium-resolution spectral data;

Topology of stellar coronae

Proceedings of the International Astronomical Union, 2006
AbstractWhile the existence of cycles in stellar chromospheric flux has been known for some time, the nature of the corresponding coronal response has been more elusive. We describe recent results on the relationship between cyclic variations in surface magnetic flux and coronal structure and re-assess the role of prominence observations in ...

Solar and stellar coronae

Advances in Space Research, 1990
A review of the observational facts of the X-ray corona of the sun suggests that the dissipation of waves plays at most a minor role in heating the corona. On the other hand, the random continuous shuffling and mixing of the footpoints of the bipolar magnetic fields, in which the X-ray corona resides, causes the spontaneous appearance of current sheets.

Element Abundances in Stellar Coronae

1996
About two years ago, the intrigue of the solar “FIP Effect”—that coronal abundances of elements with a low FIP (≲ 10 eV; e.g Fe, Mg, Si, Ca) are observed to be enhanced relative to those of high FIP elements (≳ 10 eV; e.g. O, Ne, S; see e.g. the review by Meyer 1993)—prompted us to study stellar coronal abundances based on new EUV spectra obtained with

Stellar Chromospheres, Coronae, and Winds

1986
The three subjects listed in the title of this chapter were originally defined for phenomena that are observed in the Sun. Observations of other stars have now been made at a wide range of wavelengths and have revealed that one or more of these phenomena are present in stars of every class.
