BACKGROUND Alzheimer's disease (AD) and several neurodegenerative disorders known as tauopathies are characterized by misfolding and aggregation of tau protein. Although several studies have suggested the potential of traditional Chinese medicine (TCM) as treatment for neurodegenerative diseases, the role of TCM in treating AD and tauopathies have not been well explored. MATERIALS AND METHODS...

An ionic liquids (IL)-based microwave-assisted approach for extraction and determination of flavonoids from Bauhinia championii (Benth.) Benth. was proposed for the first time. Several ILs with different cations and anions and the microwave-assisted extraction (MAE) conditions, including sample particle size, extraction time and liquid-solid ratio, were investigated. Two M 1-butyl-3-methylimid...

The occurrence of diterpenoids from roots and aerial parts of the species of the genus Stachys (Lamiaceae, Labiatae) is reviewed. The presence of these diterpenoids in other taxa and their biological properties have been also reviewed.

The essential oil obtained from the aerial parts of the Turkish endemism Stachys aleurites (Lamiaceae) has been studied. The main constituents were sesquiterpene hydrocarbons: bcaryophyllene (33.7%), bicyclogermacrene (14.5%) and germacrene D (9.6%). The main monoterpene was a-pinene (8.4%). Some chemotaxonomical considerations have been provided. 2004 Elsevier Ltd. All rights reserved.

This paper investigates hedge fund performance and risk. The empirical evidence indicates that hedge funds differ substantially from traditional investment vehicles such as mutual funds. The funds with watermarks significantly outperform the funds without watermarks. The average hedge fund returns are related positively to incentive fees, the size of the fund, and the lockup period. Hedge funds...

CONTEXT Croton cajucara Benth is a plant found in Amazonia, Brazil and the bark and leaf infusions of this plant have been popularly used to treat diabetes and hepatic disorders. OBJECTIVES This study investigated effects hepatics alterations and genotoxic and antidiabetic effect of Croton cajucara Benth bark extracts treatment in streptozotocin-induced diabetic rats. METHODS Male Wistar ra...

Stachys officinalis L., palustris sylvatica L. (Lamiaceae) are widely used as herbal remedies. In this study, comparative assessment of the phenolic acids, flavonoids, anthocyanin, and tannins content, together with antioxidant activity extracts obtained from flowers, leaves stems was performed. Phenolic acids determined by HPLC method reached highest values in flower extract S. palustris, stem...

BACKGROUND AND AIMS A test was made of the hypothesis that papilionate legume flowers filter pollinators according to their ability to exert strength to open flowers to access rewards. In addition, interactions with pollen vectors were expected to explain the structural complexity of the architecture of these flowers since operative flower strength may be determined by a combination of morpholo...

As invasive plant species are a major driver of change on oceanic islands, their control is an important challenge for restoration ecology. The post-control recovery of native vegetation is crucial for the treatments to be considered successful, but few studies have evaluated the effects of control measures on both target and non-target species. To investigate the efficiency of manual control o...
