Sporisorium elegantis, a smut fungus on Thelepogon elegans, is reported for the first time from Benin (West Africa). Based on this collection, an emended description and illustration of this rare species are provided. The geographical distribution of Sporisorium elegantis is documented for Benin, Nigeria and India. The disjunctive occurrence of this species between (western) Africa and India is interesting, though not exceptional in smut fungi. The mechanisms responsible for such a distribution pattern are not known.

A population of the rare species Strongylidium pseudocrassum Wang and Nie, 1935, was discovered from a lagoon in the northern region of Rio de Janeiro, Brazil, and its morphology was investigated through protargol-impregnation, scanning electron microscopy and in vivo observations. Morphogenetic events of cell division and physiological reorganization were described for the first time to this species. It was found that S. pseudocrassum has the ventral cirral rows organized in the same manner as Pseudouroleptus caudatus Hemberger, 1985. However two independent primordia VI, one for the proter and other for the opisthe, are generated intrakinetally from the rightmost ventral cirral row. In addition, dorsal kineties replicate entirely “de novo” and do not fragment. Based on the data obtained, the genus Strongylidium was redefined and the species currently assigned to it were classified into five groups according to current knowledge on their ciliature and the combination S. lentum (Biernacka, 1963) nov. comb. is proposed.

Herein we report for the first time the occurrence of Phaenomys ferrugineus in the state of Minas Gerais and present additional data on the geographical distribution of Abrawayaomys ruschii and Rhagomys rufescens in this state. These latter two species were reported from some localities in the Atlantic Forest of Brazil, but their presence in Minas Gerais state is restricted to few localities. These data reinforce the necessity of surveys over long periods of time and the use of pitfall traps in order to establish the real geographical distribution of small mammal species and to indicate priority areas for the conservation of this group of mammals.

First Time

: Melanoma is the most life-threatening and aggressive class of skin malignancies. The incidence of melanoma has steadily increased. Metastatic melanoma is greatly resistant to standard anti-melanomatreatments such as chemotherapy, and 5-year survival rate of cases with melanoma who have metastatic form of disease is less than 10%. The contributing role of apoptosis, angiogenesis and autophagy in the pathophysiology of melanoma has been previously demonstrated. Thus, it is extremely urgent to search for complementary therapeutic approachesthat couldenhance the quality of life of subjects and reduce treatment resistance and adverse effects. Resveratrol, known as a polyphenol component present in grapes and some plants, has anti-cancer properties due to its function as an apoptosis inducer in tumor cells, and anti-angiogenic agent to prevent metastasis. However, more clinical trials should be conducted to prove resveratrol efficacy. : Herein, for first time, we summarize current knowledge of anti-cancerous activities of resveratrol in melanoma.
