The excessive production of reactive oxygen species in nervous tissues is considered one of the major risk factors of neurodegenerative diseases. During the last two decades, much attention has been paid to the antioxidant and anti-inflammatory activity of natural products and compounds isolated from natural products which are often characterized by high efficacy and low adverse effects. Berberine is an isoquinoline alkaloid, widely present in different medicinal herbs, especially in the genus Berberis. It is mainly used as antidiarrhoeal, antibacterial, antifungal, and antiprotozoal agent. However, current research has focused on its beneficial role in neurodegenerative diseases, mainly due to its powerful antioxidant effect. The therapeutic potential of Berberine in different neurodegenerative diseases such as Alzheimer, Parkinson and Huntington disease has been brought to evidence by numerous studies. However, a limited number of reviews focus on the beneficial role of Berberine against neurodegeneration. The main objective of this review is to discuss the role of oxidative stress in neurodegeneration and the potential role of antioxidant compounds, in particular Berberine which is analyzed in its chemical structure, source, bioavailability, therapeutic potential, with special attention to its mechanism of action at a molecular level.

“…However, it seems clear that lipid accumulation in T. arborum was probably more sensitive to nitrogen starvation stress rather than strong light irradiance. Even though the lipid content in T. arborum is lower than that reported for the filamentous microalgae Tribonema minus (Wang et al, 2014), it is still comparable to filamentous algal Spirogyra singularis (Nabavi et al, 2013), and even much higher than Spirulina platensis and Limnothrix sp. (Economou et al, 2015).…”

h i g h l i g h t sT. arborum could simultaneously synthesize high amounts of carotenoids and lipid. Carotenoids (mainly b-carotene) accounted for ca. 5% in the microalgal lipid. First report of lipid and fatty acid accumulation characteristics in T. arborum. a r t i c l e i n f o t r a c tDuring the study of Trentepohlia arborum it became clear that its cells are rich in lipids and carotenoids. Thus, lipid content, composition and fatty acids profiles in individual lipid classes, as well as pigment profiles, responding to different culture conditions, were further investigated. The results showed that the predominant carotenoids and lipid fraction in total lipid in this study was b-carotene and TAG, respectively. The lipid content increased significantly under high light while nitrogen-replete conditions induced the highest carotenoids content. However, only with a double stress of high light and nitrogen-deficiency it was possible to maximize the productivities of both carotenoids and lipids. Carotenoids (mainly b-carotene) accounted for ca. 5% of the microalgal lipid under the double stress. Data herein show the potential of T. arborum for the production of both lipids and carotenoids, and hence provide an appropriate way to produce different products from T. arborum.

“…Plants and plant products are rich sources of natural polyphenolic antioxidants such as flavonoids, which can scavenge free radicals while demonstrating potent antiinflammatory properties and low adverse effects (Nabavi et al, 2012b;Nabavi et al, 2013b;Nabavi et al, 2014;Nabavi et al, 2015c). At present, there are numerous scientific evidences regarding the beneficial effects of natural products in human diseases (Nabavi et al, 2012a;Nabavi et al, 2013a;Nabavi et al, 2015a;Nabavi et al, 2015b;Nabavi et al, 2015d). Rhodiola rosea L. is an important plant species from the genus Rhodiola.…”

Rhodiola rosea L. (roseroot) is a common member of the family Crassulaceae, known as one of the most important popular medicinal plants in the northern region of Europe. The roots of R. rosea possess a wide range of pharmacological activities such as antioxidant, antiinflammatory, anticancer, cardioprotective, and neuroprotective effects that are because of the presence of different phytochemicals such as phenols and flavonoids. In addition, the presence of salidroside, rosavins, and p-tyrosol are responsible for its beneficial effects for the treatment of on depression, fatigue, and cognitive dysfunction. A plethora of studies report that R. rosea has potent neuroprotective effects through the suppression of oxidative stress, neuroinflammation, and excitotoxicity in brain tissues and antagonism of oncogenic p21-activated kinase. However, to our knowledge, no review articles have been published addressing the neuroprotective effects of R. rosea. Therefore, the present article aims at critically reviewing the available literature on the beneficial effects of R. rosea on as a therapeutic strategy for the treatment of Alzheimer's disease and other neurodegenerative diseases where oxidative stress plays a major role in disease development and progression. We also discuss the cultivation, phytochemistry, clinical impacts, and adverse effects of R. rosea to provide a broader insight on the therapeutic potential for this plant.
