BACKGROUND Alzheimer's disease is a neurodegenerative disease, characterized by progressive decline in memory and cognitive functions, that results from loss of neurons in the brain. Amyloid beta (Aβ) protein and oxidative stress are major contributors to Alzheimer's disease, therefore, protecting neuronal cells against Aβ-induced toxicity and oxidative stress might form an effective approach f...

This paper presents a dynamic principal-agent model of aquatic species invasions in which a manager, concerned about the spread of invasive species across lakes by boaters, sets interseasonal management controls on a lake-by-lake basis, and ...

antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical-induced oxidative stress. a variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. this article describes a test method for screening the antioxidant activity of 60 iranian plants o...

P olyploidy is a prominent chromosomal/genetical feature in most flowering plant groups (1, 2). Change in the number of chromosome sets (and thus gene dosage) is an important factor in the genesis of new species, in part because plants with higher ploidal levels often have ecological tolerances that differ from those of their progenitors. Plant evolutionists have been very interested in the ori...

Throughout many years of studying mycopopulation of weeds, we have found fungi of the Diaporthe/ Phomopsis complex interesting to research. After years of examining plants of Achillea millefolium L., some of them exhibited symptoms of infection typical for Diaporthe/Phomopsis species. A. millefolium was usually found in uncultivated, pasture and forest flora, but also in or nearby sunflower fie...

This study was done to identify the content compounds of Achillea wilhelmsii (A. wilhelmsii) and to evaluate its hypoglycemic and anti-hypercholesterolemic activity and effect on inflammatory mediators. The extracts and fractions of A. wilhelmsii were thoroughly analyzed using high performance liquid chromatography (HPLC), and the total content of phenols and flavonoids was determined. The hypo...

This study aimed to evaluate the phytochemical features of medicinal species Asteraceae family, their mineral elements, antioxidants, vitamins, and amino acids. The studied included common yarrow (Achillea millefolium L.), chicory (Cichorium intybus German chamomile (Chamomilla recutita (L.) Rauschert) collected in Ile Alatau Mountain (Trans-Ili Alatau), Kazakhstan. plants were harvested July 2...
