Of the more than 100 different human papillomavirus types (HPVs), the "high-risk" HPVs are associated with the vast majority of cervical carcinoma, and a pathologically distinct group of oropharyngeal tumors. In addition, other HPVs are associated with cutaneous tumors, in particular epidermodysplasia verruciformis and non-melanoma skin cancers. In general, HPV-associated cancers arise from a s...

Epidermodysplasia verruciformis (EV) is a rare genodermatosis with an autosomal recessive pattern, characterized by an unique susceptibility to chronic cutaneous infections involving specific human papilloma virus (HPV) types in the genus b. Acquired EV, with clinical features similar to those in congenital EV, occurs only in immunocompromised patients, including those with HIV, lymphoma, trans...

INTRODUCTION We report the first find of Lutzomyia longipalpis in the State of Paraná, Brazil. METHODS The specimens were captured in the urban area of the municipality of Foz do Iguaçu, with Falcão light traps, in domiciliary and peridomiciliary areas of 61 properties, on two consecutive nights from 18:00 to 06:00hs in March 2012. RESULTS We captured 40 specimens of Lu. longipalpis and 54 ...

THE ideal of prophecy is central to the life and works of the religious philosopher and poet Vladimir Solov'ev (I853-I900). Although its importance is generally acknowledged, little attempt has been made to analyse the way in which Solov'ev constructed his ideal and came to be regarded as a prophetic figure in his own right. And yet this subject is of profound interest, not only for our underst...

A recent large-scale retrospective study has revealed that the frequency and aggressiveness of extraocular sebaceous carcinoma is comparable with that of the periocular counterpart (1) and a signiflcant number of extraocular sebaceous carcinomas show regional and widespread métastases (2). However, sentinel lymph node (SLN) biopsy has seldom been used for identifying regional nodal metastasis i...

Surprisingly, skew derivations rather than ordinary derivations are more basic (important) object in study of the Grassmann algebras. Let Λn = K⌊x1, . . . , xn⌋ be the Grassmann algebra over a commutative ring K with 12 ∈ K, and δ be a skew K-derivation of Λn. It is proved that δ is a unique sum δ = δ ev + δ of an even and odd skew derivation. Explicit formulae are given for δ and δ via the ele...
