We screened serum samples referred to the national reference laboratory in Guatemala that were positive for chikungunya or dengue viruses in June 2015. Co-infection with both viruses was detected by reverse transcription PCR in 46 (32%) of 144 samples. Specimens should be tested for both arboviruses to detect co-infections.

This is the first report on circulating canine rotavirus in Mexico. Fifty samples from dogs with gastroenteritis were analyzed used polymerase chain reaction and reverse transcription polymerase chain reaction in order to identify parvovirus and rotavirus, respectively; 7% of dogs were infected with rotavirus exclusively, while 14% were co-infected with both rotavirus and parvovirus; clinical s...

Local structure in the colossal thermal expansion material Ag3[Co(CN)6] is studied here using a combination of neutron total scattering and reverse Monte Carlo (RMC) analysis. We show that the large thermal variations in cell dimensions occur with minimal distortion of the [Co(CN)6] coordination polyhedra, but involve significant flexing of the Co–CN–Ag–NC– Co linkages. We find real-space evide...

The Cover Feature illustrates a mesmerizing flip-cum-reverse sequence of anion/cation storage chemistry in reverse dual ion battery (RDIB). This ground-breaking RDIB employs selective redox potential materials, such as ferrocene and Prussian blue analogue, ZnCl2-water-in-salt electrolyte (ZnCl2-WiSE). By leveraging high concentration, the (de)insertion potentials anions cations are expertly man...

in this paper, we present some inequalities for the co-pi index involving the some topological indices, the number of vertices and edges, and the maximum degree. after that, we give a result for trees. in addition, we give some inequalities for the largest eigenvalue of the co-pi matrix of g.

in this paper, we introduce the notion of primal strong co-ideals and give some results involving them. it is shown thatsubtractive strong co-ideals are intersection of all primal strong co-ideals that contain them. also we prove that the representation of strong co-ideals as reduced intersections of primal strong co-ideals is unique.

OBJECTIVES To compare plasma antiretroviral concentrations in HIV-HCV co-infected and in matched HIV mono-infected patients. METHODS This was a cross-sectional, observational study. Antiretroviral trough concentrations (C(min)) in plasma were measured in HIV-HCV co-infected patients with liver disease documented by liver biopsy, matched with HIV mono-infected patients according to gender and ...

in this work needle like hydroxy apatite were synthesized in a reverse microemulsion droplets of water in cyclohexane, separated by a cationic surfactant and co-surfactant, in the presence of na-polyacrylate (paa) as an anionic polyelectrolyte. characterization of the as formed hap nanoparticles at the room temperature were carried out by x-ray diffraction (xrd) and fourier transform infrared s...

Strong electroluminescence (EL) of reverse-biased Er-doped β-Ga2O3 Schottky barrier diodes is demonstrated. The devices are prepared by pulsed laser deposition featuring co-doping n-type dopant Si and isovalent Er, while contacts formed Pt-sputtering. display a rectification ratio more than nine orders magnitude at ±3 V in the virgin state, but under reverse bias that yields leakage current den...
