In this paper, nine species of bolete fungi belonging to genera Boletus, Leccinum, Suillus and Xerocomus are reported from Arasbaran (E. Azarbaijan Province, N.W. Iran).From identified species Boletus edulis, B. erythropus, B. fechtneri, B. fragrans and X. ferrugineus are reported from Arasbaran as new for Iran.B. pulverulentus, L. pseudoscabrum, S. collinitus and S. granulatus have already bee...

parkinson’s disease (pd) is a rather common movement disorder as a result of the degeneration of dopaminergic neurons within the substantianigra. current treatments for pd afford symptomatic relief with no prevention of disease progression. due to the neuroprotective and anti-apoptotic potential of the isoquinoline alkaloid berberine (bbr), this study was conducted to assess whether bbr pretrea...
