Immunohistochemical detection of estrogen receptor α in articular chondrocytes from cows, pigs and humans: in situ and in vitro results

Abstract: Clinical observations suggest that estrogens are involved in the pathogenesis of postmenopausal osteoarthritis, but only little is known about the influence of these hormones on articular cartilage cells. The effect of estradiol is mediated by estrogen receptors alpha and beta. The goal of the present study was to search for estrogen receptor alpha in articular tissue from cows, pigs and humans by immunohistochemistry to form a basis for in vitro studies. In addition, we also tried to detect estrogen receptor alpha in cultivated articular chondrocytes from cows and bulls under certain culture conditions. Estrogen receptor alpha is detected by the use of antibody 13H2 in articular chondrocytes from cows, bulls, pigs and humans. Chondrocytes are physiologically exposed to reduced oxygen tension. In isolated articular chondrocytes from cows and bulls incubated either with 21% O2 or with 5% O2 positive cells were also found. These positive results therefore encourage testing the influence of estradiol on cultivated articular cartilage cells in these species under different culture conditions.

Device and method for removing heat energy from a compartment

Abstract: Removal of heat energy from a compartment containing a heat engine is effected by drawing air in from the compartment through at least one opening made in a duct which passes through the compartment and in which air, entering from one face of the compartment and opening to the outside to a reduced-pressure zone, flows.

Additive-assisted supramolecular manipulation of polymer:fullerene blend phase morphologies and its influence on photophysical processes

Abstract: It is well known that even small variations in the solid-state microstructure of polymer:fullerene bulk heterojunctions can drastically change their organic solar cell device performance. We employ pBTTT:PC61BM as a model system and manipulate co-crystal formation of 1 : 1 (by weight) blends with the assistance of fatty acid methyl esters as additives. This allows us to evaluate the role of the intermixed phase in such binary blends through manipulation of their phase morphology—from fully intercalated to partially and predominantly non-intercalated systems—and its effect on the exciton- and carrier- dynamics and the efficiency of charge collection, with relevance for future device design and manufacturing.

G+++ Invariant formulation of gravity and M-theories: exact intersecting brane solutions

Abstract: The set of exact solutions of the non-linear realisations of the +++ Kac-Moody algebras is further analysed. Intersection rules for extremal branes translate into orthogonality conditions on the positive real roots characterising each brane. It is proven that all the intersecting extremal brane solutions of the maximally oxidised theories have their algebraic counterparts as exact solutions in the +++-invariant theories. The proof is extended to include the intersecting extremal brane solutions of the exotic phases of the maximally oxidised theories.
