13. Biological bases for a possible effect of cannabidiol in Parkinson’s disease
Current pharmacotherapy of Parkinson’s disease (PD) is palliative and unable to modify the progression of neurodegeneration. Treatments that can improve patients’ quality of life with fewer side effects are needed, but not yet available. Cannabidiol (CBD), the major non-psychotomimetic constituent of cannabis, has received considerable research attention

15. Structural Assessment of Chemical Constituent of Sidaguri (Sida rhombifolia Linn) and Its Ability to Inhibit Cyclooxygenase
Abstract Objective: To elicit the structure of isolated compounds from roots of sidaguri (Sida rhombifolia Linn). Material and Methods: Several organic standard protocols were involved, including extraction, fractionation, and phytochemical testing. Further spectroscopy methods, FTIR and 1HNMR, were used to determine the predicted structure of molecules, w

16. Antileishmanial in vitro activity of essential oil from Myrciaria plinioides, a native species from Southern Brazil
In South American folk medicine members of the genus Myrciaria are used for the treatment of malaria, diarrhoea, asthma, inflammation and post-partum uterine cleansing. The aim of this work was to evaluate its antileishmanial properties (in vitro) of essential oil derived from leaves of Myrciaria plinioides D. Legrand, a plant species that is native in South

17. Ameliorative Effects of Thymoquinone on Sperm Parameters and Testosterone Level of Nicotine-Treated Sprague Dawley Rats
Abstract Thymoquinone (TQ), the main constituent of the volatile oil derived from Nigella sativa has shown pharmacological benefits against various diseases while nicotine is an active component in cigarette that is known to be detrimental. This study was conducted to assess the ameliorating effects of TQ on sperm count, membrane, mitochondria and testostero

20. Bioactivity and action mechanism of green propolis against Pythium aphanidermatum
Abstract: We have established how natural compounds from green propolis collected by the species Apis mellifera act against the growth of Pythium aphanidermatum. On the basis of mass spectrometry (Q-ToF MS), we determined that Artepillin C, the major constituent of green propolis, underlies the effect and displays activity against P. aphanidermatum at a mini

21. The compound, diallyl disulfide, enriched in garlic, prevents the progression of doxorubicin-induced nephropathy
Abstract The main medicinal property of garlic is mostly attributed to its organosulfur compounds, of which the oil-soluble diallyl disulfide (DADS) is the principal component of distilled garlic oil. Nuclear factor erythroid 2-related factor 2 (Nrf2) is an important cellular regulator in response to oxidative stress. This study assessed the possible protect

22. Epigallocatechin Gallate (EGCG) Inhibited the Alv-J-Induced Apoptosis in Df-1 Cells by Inactivation of Nuclear Factor κb Pathway
ABSTRACT Avian leukosis virus subgroup J (ALV-J), a member of the retroviridae family, can infect both broilers and layers and induce a spectrum of different neoplasms, resulting in serious economic losses in poultry production. Epigallocatechin-3-gallate (EGCG), the major constituent of green tea, has demonstrated remarkable anti-inflammatory and cancer che
