Empirical relationships on the properties of the Extended Red Emission (ERE) are presented. They are based on published observational data and on new results obtained on reflection nebulae illuminated by cold stars. The plot of the width versus the central wavelength of the ERE band is in agreement with laboratory properties of the materials commonly proposed as the ERE carriers. But this is no...

O objetivo deste estudo foi relatar as experiências vivenciadas na pós-graduação, no estágio docente do ensino superior, Ensino Remoto emergencial (ERE), e suas contribuições para a formação docente. Tratou-se de um qualitativo, com o apoio da observação participante Análise Textual Discursiva (ATD). Elencamos três categorias análise: Adoção das Tecnologias Informação Comunicação (TICs); Prátic...

Coix lacryma-jobi, commonly known as job's tear, is a tall grain-bearing tropical plant of the family Poaceae. The ethanolic root extract (ERE) of the plant was investigated for the first time for anti-venom activity against Indian cobra Naja naja venom. In-vitro studies were conducted to determine neutralization of phospholipase A2 (PLA2) activity of the Naja naja venom by the ERE. ERE showed ...

The aim of this study is to characterize rings having the following properties for a non-trivial idempotent element e R, U (eRe) = + eJ(R)e J (and N (eRe)),where (-), (-) and denote group units, set all nilpotent elements Jacobson radical respectively. In present paper, some characterizations are also obtained in terms every form u, where e2 ∈ R u U(eRe).

We have examined the ability of the high-mobility group protein 1 (HMG1) to alter binding of the estrogen receptor DNA-binding domain (DBD) to the estrogen response element (ERE). HMG1 dramatically enhanced binding of purified, bacterially expressed DBD to the consensus vitellogenin A2 ERE in a dose-dependent manner. The ability of HMG1 to stabilize the DBD-ERE complex resulted in part from a d...

Anacardic acid (AnAc; 2-hydroxy-6-alkylbenzoic acid) is a dietary and medicinal phytochemical with established anticancer activity in cell and animal models. The mechanisms by which AnAc inhibits cancer cell proliferation remain undefined. AnAc 24:1(omega5) was purified from geranium (Pelargonium x hortorum) and shown to inhibit the proliferation of estrogen receptor alpha (ERalpha)-positive MC...

BACKGROUND Endocrine-disrupting chemicals (EDCs) influence the activity of estrogen receptors (ERs) and alter the function of the endocrine system. However, the diversity of EDC effects and mechanisms of action are poorly understood. OBJECTIVES We examined the agonistic activity of EDCs through ERα and ERβ. We also investigated the effects of EDCs on ER-mediated target genes. METHODS HepG2 ...
