This study was conducted to evaluate and compare the levels of aflatoxin M1 in raw and pasteurized milk samples during different seasons by Enzyme- Linked Immuno Sorbent Assay in Sanandaj, Iran. In 257 (94.49%) out of 272 milk samples the presence of aflatoxin M1 was detected in concentrations ranging between 0.007 and 115.930 ng/l. AFM1 level in 12 (4.4%) of positive samples were higher than t...

soil salinity affects ions concentrationss of plant tissues and this may alter the merits quality of medicinal plants. experiments were conducted during 2003 at the the isfahan university of technology campus, isfahan, iran, to assess the effects of five soil salinity levels (3.2, 3.6, 4.5, 5.4 and 7.5 ds m-1) on na, k, and ca contents of borage and echium. each plant species was studied in a s...
—We provide substantial new information on the breeding biology of the Rusty-breasted Antpitta (Grallaricula ferrugineipectus ferrugineipectus) from 40 nests during four consecutive breeding seasons at Yacambú National Park in Venezuela. Vocalizations are quite variable in G. ferrugineipectus. Nesting activity peaked in April when laying began for half of all nests monitored. The date of nest i...
