Effects of prior light exposure on early evening performance, subjective sleepiness, and hormonal secretion

Jean-Louis Scartezzini, Mirjam Münch, Friedrich Linhart, Apiparn Borisuit

In sighted humans, light intensity, timing, exposure duration, and spectral composition of light are important to entrain the endogenous circadian pacemaker to the 24-h day-night cycle. We tested the impact of two realistic office lighting conditions durin ...

Restoration of direct pathway glycogen synthesis flux in the STZ-diabetes rat model by insulin administration

Ana Francisca Leal Silva Soares

Type 1 diabetes subjects are characterized by impaired direct pathway synthesis of hepatic glycogen that is unresponsive to insulin therapy. Since it is not known whether this is an irreversible defect of insulin-dependent diabetes, direct and indirect pat ...

The Lipopolysaccharide from Capnocytophaga canimorsus Reveals an Unexpected Role of the Core-Oligosaccharide in MD-2 Binding

Matteo Dal Peraro, Marco Stenta

Capnocytophaga canimorsus is a usual member of dog's mouths flora that causes rare but dramatic human infections after dog bites. We determined the structure of C. canimorsus lipid A. The main features are that it is penta-acylated and composed of a "hybri ...

Local glucocorticoid production in the mouse lung is induced by immune cell stimulation

Kristina Schoonjans

Background: Glucocorticoids (GC) are potent anti-inflammatory and immunosuppressive steroid hormones, mainly produced by the adrenal glands. However, increasing evidence supports the idea of additional extra-adrenal sources of bioactive GC. The lung epithe ...

Neurobiological Mechanisms Involved in the Establishment and Maintenance of Dominance Hierarchies and its Modulation by Stress in Rats

Maria del Carmen Sandi Perez, Marjan Timmer

Stress can have a strong and long lasting effect on the establishment and maintenance of dominance hierarchies in rats. When two rats of a pair have not been stressed (non-stressed pair) before a first social encounter, they establish a dominance hierarchy ...

High hopes for RANKL: will the mouse model live up to its promise?

Cathrin Brisken, Tamara Tanos

The steroid hormones, estrogens and progesterone are key drivers of postnatal breast development and are linked to breast carcinogenesis. Experiments in the mouse mammary gland have revealed that they rely on paracrine factors to relegate their signal loca ...

A role for glucocorticoids in the long-term establishment of a social hierarchy

Maria del Carmen Sandi Perez, Marjan Timmer

Stress can affect the establishment and maintenance of social hierarchies. In the present study, we investigated the role of increasing corticosterone levels before or just after a first social encounter between two rats of a dyad in the establishment and ...

Quantification of brain glycogen concentration and turnover through localized C-13 NMR of both the C1 and C6 resonances

Rolf Gruetter, Lijing Xin, Ruud van Heeswijk

We have recently shown that at isotopic steady state C-13 NMR can provide a direct measurement of glycogen concentration changes, but that the turnover of glycogen was not accessible with this protocol. The aim of the present study was to design, implement ...

Distribution of type I collagen morphologies in bone: Relation to estrogen depletion

Blake William Erickson

Bone is an amazing material evolved by nature to elegantly balance structural and metabolic needs in the body. Bone health is an integral part of overall health, but our lack of understanding of the ultrastructure of healthy bone precludes us from knowing ...

Novel chemico-mechanical approach towards long-term implantable glucose sensing

Peter Ryser, Jean-Michel Sallese, Eric Meurville, Christophe Boss

The proof of concept of a continuously sensing affinity device based on the glucose-dependent viscosity of a sensitive solution containing dextran and Concanavalin A has been successfully demonstrated. The biosensor incorporates a piezoelectric diaphragm a ...
