The phylogeny of Nolana (Solanaceae), a genus primarily distributed in the coastal Atacama and Peruvian deserts with a few species in the Andes and one species endemic to the Galápagos Islands, was reconstructed using sequences of four plastid regions (ndhF, psbA-trnH, rps16-trnK and trnC-psbM) and the nuclear LEAFY second intron. The monophyly of Nolana was strongly supported by all molecular ...

Sebertia acuminata (Sapotaceae) from New Caledonia has been shown to be a hyperaccumulator of nickel. The nickel content of the latex (25.74 percent on a dry weight basis) is easily the highest nickel concentration ever found in living material. The nickel is in the form of a low-molecular-weight, water-soluble organic complex.

Condylomata acuminata caused by human papillomavirus (HPV), a sexually transmitted virus, are rarely seen beyond the external genitalia and anal region. Here, a patient with innumerable condyloma acuminatum of the bladder is presented. Attempted surgical resection was performed and intraoperative photographs are presented.

Four new species of the huntsman spider genus Pseudopoda Jäger, 2000 are described from Southern China: Pseudopoda acuminata sp. n. from Suiyang County, Guizhou Province, P. emei sp. n. from Emei Mountain, Sichuan Province, P. lacrimosa sp. n. from Fugong County and Tengchong County, Yunnan Province, and P. robusta sp. n. fromJinyun Mountain, Chongqing Municipality.

Four asclepiadaceous types not listed in a previous type catalogue of the collections of the Instituto de Ecología y Sistemática, Habana, Cuba (HAC) are provided, along with a discussion of typification problems associated with the associated Charles Wright collections. Lectotypifications are provided for Gonolobus stephanotrichus Griseb., Orthosia acuminata Griseb., Orthosia oblongata Griseb.,...

Ancient literature alluded to the use of a number of plants/preparations as sex enhancer. One of such botanicals is Massularia acuminata in which the stem has been acclaimed to be used as an aphrodisiac. Documented experiments or clinical data are, however, lacking. Therefore, this study was undertaken to evaluate the acclaimed aphrodisiac activity of M. acuminata stem. Sixty male rats were com...

Little is known about the demographic consequences of fragmentation for plant populations. By assessing the population structure of a common herb ( Heliconia acuminata ) in an experimentally fragmented landscape in the central Amazon, we tested the predictions that fragmentation could reduce population density, alter population structure, and reduce reproductive effort. Population density in co...

Condyloma acuminata, the anogenital expression of human papillomavirus commonly called genital warts, is the focus here. Of particular emphasis is HPV's association with genital cancer. The use of androscopy for the examination and treatment with cryotherapy, podophyllin, trichloroacetic acid, and 5-fluorouracil also are assessed.

Eight cases of bowenoid papulosis are reported. The clinical diagnoses were confirmed by histology. In one case an immunoperoxidase method showed the presence of papillomavirus antigen in the nucleus of the most superficial epidermal cells. We consider bowenoid papulosis to be a condition with specific features that distinguish it clinically and histologically from carcinoma in situ and condylo...
