In February of 1996 a human adenovirus (formerly known as Ad-Cor-96-487) was isolated from the stool an AIDS patient who presented with severe chronic diarrhea. To characterize this apparently novel pathogen potential public health significance, complete genome sequenced to elucidate its origin. Bioinformatic and phylogenetic analyses demonstrate that virus, heretofore referred HAdV-D58, contains hexon gene well recombinant fiber gene. addition, serological analysis demonstrated HAdV-D58 has...
O estudo das mulheres no esporte ainda apresenta dificuldade por causa da ambiguidade dos hormônios progesterona e estrógeno durante as fases do ciclo menstrual. Porém, diversos estudos tentam identificar a relação rendimento esportivo com esse evento tão importante presente na vida mulheres. Diante exposto, o teve como objetivo analisar cada fase menstrual pode influenciar desempenho de salto atletas voleibol. Foram realizados dois tipos saltos (tipo CMJ SJ) contou 7 participantes, uma...
Water resources contaminated with wastewater are an important source for the dissemination of enteric viruses impact on health population. The aim study was to assess viral contamination freshwater from a dam in Argentina by using infectious enterovirus detection, RNA amplification, and genetic characterization five associated diarrhea hepatitis. Enterovirus infectivity (iEV) evaluated cell culture direct immunofluorescence. detection genome rotavirus (RV), human astrovirus (HAstV),...
<i>Objectives:</i> This study was carried out in order to evaluate the efficacy of recently developed picobirnavirus (PBV) sets primers and establish phylogenetic relationships Argentine strains with PBV isolated China USA. <i>Methods:</i> Thirteen fecal specimens tested as positive for by polyacrylamide gel electrophoresis were analyzed reverse transcription-polymerase chain reaction assays using target genomic segments 2 The amplicons sequenced analyzed....
In recent years, several types of human adenovirus (HAdV) have arisen from the recombination between two or more previously known HAdV types, but their epidemiology is poorly understood. this study, we investigated circulation HAdV-58, a recently described isolated an HIV-positive patient in Córdoba city, Argentina. For purpose, 30-month survey was conducted to study presence type sewage samples collected at inlet wastewater treatment plant Complementarily, virus sought stools patients....
Abstract Viral transformation models may be useful to detect and map human tumor suppressor genes. BK virus (BKV), a papovavirus, readily transforms rodent cells but is unable transform cells, suggesting that oncosuppressive functions expressed in control BKV oncogenic activity. We have transferred chromosome 6 BKV‐transformed mouse pRPcTlssI cells. The great majority of the colonies growing selective medium degenerated by senescence. Only five hybrid pRPcTIssI/H6 clones maintained...
Abstract Human herpesvirus 6 (HHV‐6) and 7 (HHV‐7) are common opportunistic agents in immunocompromised hosts, although infection with HHV‐6 HHV‐7 can also be observed immunocompetent hosts. Despite similar biology epidemiology, this study evaluated differences the IgG subclass distribution associated seropositive, healthy persons. The identified subclasses were compared detection of DNA. For these assays, sera, plasma, saliva samples obtained from 40 blood donors Argentina who seropositive...
Este estudo examina as necessidades e perspectivas da formação continuada de professores no século XXI, considerando os desafios impostos pela era digital transformações cenário educacional. A pesquisa analisa políticas atuais docente Brasil, destacando lacunas existentes oportunidades inovação. Através uma revisão bibliográfica abrangente, o investiga tendências emergentes em continuada, incluindo a incorporação tecnologias digitais, metodologias ativas abordagens colaborativas. Os...
Background: Host immunity plays an important role in the development of human papillomavirus (HPV)‐associated disease. The HPV infection oral cyclosporin‐induced gingival overgrowth renal transplant recipients has not been investigated previously. aim this study was to establish hyperplasia through morphological changes and use situ hybridization technique. Methods: We examined 13 recipient biopsies with lesions 4 healthy mucosa samples these patients. histopathological diagnoses were...
We studied the occurrence of reovirus infection in children hospitalized with acute gastroenteritis Argentina during a 20-year interval (1981 through 2001). Three 2854 (0.10%) stools were positive for but negative adenovirus, astrovirus and rotavirus. Children infected <1 year old; one had meningoencephalitis addition to gastroenteritis. This study indicates that is an uncommon cause childhood requires medical assistance.
Abstract Rotavirus G1 strains represent the most common genotype that causes diarrhea in humans and has been incorporated into both, monovalent multivalent, rotavirus licensed vaccines. The aim of this study was to determine evolution profile rotaviruses Córdoba, Argentina, over a 27‐year period (1980–2006). Intragenotype diversity, represented by lineages within circulating strains, observed. Phylogenetic analysis VP7‐gene clinical showed circulation lineage IV V 1980s, co‐circulation I II...
Oral cancer is a process thai involves diffurent etiological factors and meehanisms in the light of current view viral cocarcinogenesis Evidenee from histology DNA hybridization studies suggests that l-lPV ingaged oral carcinogenesis. The Pathology Laboratory Dentistry School, National University Córdoba, admits approximately 20% aH patients svith cancerous lesions this city.In January 1 992-December 1997 lapse, ve examined 1950 biopsies with lesions, 4.77% (93/1950 ) which sere malignant...
SUMMARY Little is known about long-lasting measles protective immunity when exposure to wild-type or vaccine virus precedes HIV infection. The results obtained suggest that wanes and the lowest geometric mean titres (GMT) were significantly associated with vaccine-induced in individuals later developed infection (86% prevalence, GMT 164 mIU/ml) compared naturally induced HIV-infected adults (100% 340 mIU/ml, P = 0·0082) non-HIV infected (100%, 724 0·0001), non-HIV-infected 347 0·017). study...
Human herpes virus-7 (HHV-7) infection is widespread throughout the world. No data are available in Argentina about loss of maternally-derived HHV-7 immunity and natural infection.The objective this study was to characterize time when children lose maternal antibodies become susceptible infection.Sera from 39 pregnant women 207 infants between 2 29 months age were tested. Determination IgG made by indirect immunofluorescence.The seropositive ratio fell 2-4 month group (15% seropositive)...
El cambio climático afecta a las interacciones entre los sistemas hídricos, ecosistemas y la atmósfera. También aumenta el riesgo de presencia microorganismos que afectan utilizan estos recursos. impacto población sobre recursos hídricos se ha hecho más evidente en últimos años, destacando estrecha relación niveles componentes inorgánicos así como contaminación microbiológica del agua salud comunidad. La caracterización variables dan cuenta es un proceso complejo. En este trabajo propone...
