AIM: Saliva can play an important role in human herpesvirus-8 (HHV-8) transmission in endemic regions for Kaposi's sarcoma (KS). Little is known about HHV-8 oral shedding in immunocompetent individuals from non-endemic regions for KS. METHODS: We conducted a prospective study of HHV-8 salivary excretion among 59 healthy, immunocompetent individuals from São Paulo, Brazil, followed up weekly for 4 months, resulting in 16 saliva samples from each participant. Antibodies to HHV-8 latency-associated nuclear antigen (LANA) and lytic-phase antigens were investigated with immunofluorescence assays (IFA)...

Although research into the tissue engineering of vessels has proceeded at a tremendous pace, many deficiencies still need to be resolved. A well-adopted constructed vessel requires both functional and structural properties to stimulate the native vessel and resist stress and tension in vivo. In the present study, we developed a novel three-layer composite vascular scaffold consisting of differentiated vascular smooth muscle cell-, vascular endothelial cell-like cells, and a rabbit acellular vascular matrix (ACVM)-0...

Nosema bombycis is the pathogen of pébrine which brings heavy losses to sericulture every year. As a member of serine proteases, subtilisin-like protease (SLP) is related to the pathogenicity in fungi. In this study, we characterized a novel 63.8 kDa subtilisin-like protease NbSLP2 with a predicted transmembrane domain from Microsporidia, N. bombycis. RT-PCR showed that the transcript of NbSLP2 was detected from third day post infection. Immunofluorescence assay (IFA) indicated that NbSLP2 mainly scattered around the spore wall of N...

BACKGROUND: Crimean-Congo hemorrhagic fever virus (CCHFV) was detected for the first time in Mauritania in 1983 and several CCHFV outbreaks were reported in the following years. The last human case was diagnosed in 2015. However, no recent data exist about the prevalence of CCHFV in animals, although it is already described that prevalence studies in animals serve as good risk indicators. CCHFV can cause a severe hemorrhagic fever with a high case fatality rate in humans. Therefore, a precise risk assessment on the basis of updated data is very important...

Biodiesel has been introduced as an energetic matrix in several countries around the world. However, the affinity of biodiesel with the components of petrodiesel engines is a growing concern. In order to obtain information regarding the effect of biodiesel on the rubber structure, nuclear magnetic resonance technics under a new technology named as comprehensive multiphase (CMP NMR) and the imaging through desorption electrospray ionization mass spectrometry (DESI-MS imaging) were used. The (1)H CMP-DOSY NMR showed the entrapped fuel into the rubber cavities, which the higher constraint caused by the rubber structure is related to the smaller diffusion coefficient...

BACKGROUND: Scrub typhus (ST) is a disease caused by an obligate intracellular bacterium, Orientia tsutsugamushi, an organism that requires a BSL3 laboratory for propagation. The disease is hallmarked by an eschar at the site of the chigger bite, followed by the development of fever, malaise, myalgia, anorexia, and papulomacular rash. Indirect immunofluorescent assay (IFA) is the gold standard for scrub typhus diagnosis, however, the subjectivity of the assay, the need for a specialized laboratory and instruments has limited the wide use of the test in resource limited areas...

Municipal solid waste (MSW) incineration fly ash (IFA) can be potentially reused as a substitute for some raw materials, but treatment for detoxification is indispensable owing to high contents of heavy metals in fly ash. In the present work, due to excessive leaching concentration of lead (Pb), a moderate thermal treatment with sodium hydroxide (NaOH) addition was employed to stabilize Pb in IFA. The moderate thermal treatment was performed under relatively low temperature ranging from 300 to 500°C and at retention time from 1 to 3 h with NaOH addition in a range of 1 to 9%...

The present study explores the interlinkages among the operational variables of a University of Cape Town (UCT) Integrated Fixed Film Activated Sludge (IFAS) membrane bioreactor (MBR) pilot plant. Specifically, dedicated experimental tests were carried out with the final aim to find-out a constitutive relationship among operational costs (OCs), effluent quality index (EQI), effluent fines (EF). Greenhouse gas (GHG) emissions were also included in the study. Results showed that the EQI increases at low flow rate likely due to the dissolved oxygen (DO) limitation in the biological processes...

Oocyst stage of Toxoplasma gondii is characterized by a durable wall that confers a strong protection to this protozoan parasite in face of harsh environmental conditions. Thus, it is considered the key for transmission of T. gondii. Analysis of oocyst wall composition is mandatory therefore; the aim of this study was to identify novel T. gondii oocyst wall proteins and test their use in detection of these oocysts in environmental samples. Five candidates of novel T. gondii oocyst wall proteins (TgOWPs) were identified and named TgOWP8 through TgOWP12...

BACKGROUND: Infections with tick-borne rickettsiae can cause diseases well known in humans but still not so well characterized in dogs. Susceptibility to infection depends on the virulence of Rickettsia spp. and only a few of them have been described to cause disease in dogs. The aim of this study was to investigate the exposure to Rickettsia spp. among a group of pet dogs from Luanda, Angola. RESULTS: Out of 103 dogs included in the study, 62 (60.2%) were infested with ticks...
