We report the discovery of two enteroviruses detected in nasopharyngeal samples obtained from subjects with respiratory disease in Peru. Phylogenetic analysis indicated that both viruses belong to a clade within the species Human enterovirus C, which includes the recently characterized human enteroviruses 109 and 104. Members of this clade have undergone(More)

We investigated hantaviruses in rodents in the southern Amazon Basin of Peru and identified an Andes virus variant from Neacomys spinosus mice. This finding extends the known range of this virus in South America and the range of recognized hantaviruses in Peru. Further studies of the epizoology of hantaviruses in this region are warranted.
BACKGROUND Maternal heart rate (MHR) recordings are morphologically similar and sometimes coincident with fetal heart rate (FHR) recordings and may be useful for maternal-fetal monitoring if appropriately interpreted. However, similarly to FHR, visual interpretation of MHR features may be poorly reproducible. METHODS A computer algorithm for on-line MHR(More)

Our understanding of the global ecology of avian influenza A viruses (AIVs) is impeded by historically low levels of viral surveillance in Latin America. Through sampling and whole-genome sequencing of 31 AIVs from wild birds in Peru, we identified 10 HA subtypes (H1-H4, H6-H7, H10-H13) and 8 NA subtypes (N1-N3, N5-N9). The majority of Peruvian AIVs were(More)
While studying respiratory infections of unknown etiology we detected Saffold virus in an oropharyngeal swab collected from a two-year-old female suffering from diarrhea and respiratory illness. The full viral genome recovered by deep sequencing showed 98% identity to a previously described Saffold strain isolated in Japan. Phylogenetic analysis confirmed(More)

Background Cryptococcus neoformans can cause infection in immu-nocompromissed individuals, especially in patients with acquired immunodeficiency syndrome, in which menin-goencephalitis is the main clinical manifestation [1]. There are few available antifungals for cryptococcosis treatment and all of them present high toxicity, besides the reports of(More)

Background It is well known that many bioactive peptides (intra-genic) are encrypted in source proteins and that they can exert their function once released by proteolytic cleavage; e.g. hypotensive, opioids and antimicrobial peptides. However, other bioactive peptides may be " stuck " on a polipeptide chain with no cleavage sites for its release. These "(More)
Lung cancer is the most common cause of cancer deaths in both men and women. Adenocarcinoma represents about 28% of the NSCLC cases in men and 42% in women. EGFR is a member of the ERBB family of tyro-sine kinases (TK). EGFR mutations are more frequently observed in female, non-smokers, East-Asian and in patients with adenocarcinomas, and predict response(More)
