ABSTRACT Paracoccidioides brasiliensis , a thermodimorphic fungus, is the causative agent of prevalent systemic mycosis in Latin America, paracoccidioidomycosis. We present here survey expressed genes yeast pathogenic phase P. . obtained 13,490 sequence tags from both 5′ and 3′ ends. Clustering analysis yielded partial sequences 4,692 that were functionally classified by similarity to known genes. have identified several Candida albicans virulence pathogenicity homologues Furthermore, we...

Objective and background: The aim of this in vitro study was to compare the efficiency a photodynamic therapy (PDT) technique employing rose bengal (RB) methylene blue (MB) as photosensitizers (PSs) reduce viability Enterococcus faecalis, well-known pathogen found root canal systems. Currently, several clinical applications, including field endodontics, MB is employed association with red laser source for photoinactivation pathogenic bacteria. Methods: In study, used at 0.01% (31.2 mol/L)...

Members of the Acinetobacter genus are key pathogens that cause healthcare-associated infections, and they tend to spread develop new antibiotic resistance mechanisms. Oxacillinases primarily responsible for carbapenem antibiotics. Higher rates hydrolysis might be ascribed insertion sequences, such as ISAba1 sequence, near bla OXA genes. The present study examined occurrence genetic elements their relationship with susceptibility carbapenems in clinical isolates calcoaceticus-Acinetobacter...

Ischemic stroke (IS) is a multifactorial disease that presents high rates of morbimortality in Brazil. Several studies proved there link between the ABO blood group system and occurrence thrombotic events. Nonetheless, its association with IS not well established.For reason, purpose hereof was to investigate relation groups Brazilian cohort cerebrovascular diseases.Five hundred twenty-nine subjects were included over 12 months, from which 275 presented an episode 254 composed control group....

Sepsis is a systemic inflammatory response related to high mortality rates in the hospital environment. Delayed etiological diagnosis and inadequate antimicrobial therapy are associated with treatment failures. Molecular tests based on polymerase chain reaction regarded as faster more accurate procedures than culture techniques for microbial identification, providing higher rate of therapeutic success.To develop panel primers DNA fragments sepsis-related microorganisms.Primers amplification...

CONTEXT: The use of thiopurine drugs such as azathioprine and 6-mercaptopurine has become quite common in the treatment inflammatory bowel disease, transplantation acute leukemias. Despite their effectiveness, these are capable causing drug-induced toxicity with risk death by myelosuppression. It is now known that complications occur because genetic polymorphisms thiopurinemethyltransferase (TPMT) enzyme, responsible for its metabolism. OBJECTIVE: To assess prevalence methyltransferase...

Introduction: Single-nucleotide polymorphisms (SNPs) associated with hepatitis C virus (HCV) clearance were identified near the IL28B gene. Coinfection by human immunodeficiency (HIV) influences course of HCV contributing to liver damage. Nevertheless, little is known about relationship between these SNPs and HCV/HIV coinfection. Our aim was estimate relevance allelic genotypic variants rs12979860 (C/T) rs8099917 (T/G) on establishment infection in mono-infected coinfected patients....

Os estudos em biologia molecular desenvolvidos nas últimas décadas, possibilitaram grandes avanços para uma maior compreensão da carcinogênese colorretal. Na década de 80 pesquisadores descobriram proteína com a capacidade aumentar permeabilidade dos vasos sangüíneos. Inicialmente esta foi denominada como fator vascular. Estudos posteriores correlacionaram o crescimento novos sangüíneos (angiogênese), quando passou ser chamada endotelial vascular (VEGF). A VEGF tem sido apontada principal...
