Methylmercury intoxication and histochemical demonstration of NADPH-diaphorase activity in the striate cortex of adult cats

Brazilian Journal of Medical and Biological Research, 1998
The effects of methylmercury (MeHg) on histochemical demonstration of the NADPH-diaphorase (NADPH-d) activity in the striate cortex were studied in 4 adult cats. Two animals were used as control.

Interfacial Energy and Composition Controlled Self‐Stratification in Polyurethane Coatings

Macromolecular Materials and Engineering, EarlyView.
This study elucidates self‐stratification in polyurethane coatings driven by interfacial energies and composition‐dependent phase separation. Using XPS, SIMS, and Raman analyses, we reveal rapid formation of hydrophobic and hydrophilic layers and substrate‐dependent interfacial structures.

Dismantling the genus Tarenna (Rubiaceae: Pavetteae) in Africa and Madagascar, with the description of three new genera

TAXON, EarlyView.
Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

Gonadulin and Insulin‐Like Growth Factor Involved in Rhipicephalus microplus Reproduction

Entomologia Experimentalis et Applicata, EarlyView.
Insulin‐like growth factor (IGF2) in ovaries of Rhipicephalus microplus partially engorged females. Ovaries from females at different feeding stages were used to detect IGF2. ABSTRACT Gonadulin and insulin‐like growth factor (IGF) are neuropeptides synthesized by the central nervous system (CNS) of arthropods.

A Branched SNF1‐Related Protein Kinase 2 Signalling Cascade Controls ABA‐Induced Ethylene Production and Regulates Both Fruit Ripening and Reproductive Growth

Plant Biotechnology Journal, EarlyView.
ABSTRACT Control of fruit ripening, quality and yield is of major scientific, nutritional and commercial importance. The burst of ethylene (ET) production at the initiation of ripening is the most critical event controlling climacteric (CL) fruit ripening, yet little is known about how it is initiated.
