question:
To establish a single-tube single-run multiplex PCR technique that can detect single or mixed samples with four species of Plasmodium.', 'Folding primers were designed based on the fast nested PCR. The reaction component concentrations were optimized and the primers were selected based on the annealing temperature. The established single-tube single-run folding-primer multiplex PCR (FP-PCR) was tested for its sensitivity and specificity to detect single-species and mixed samples with P. vivax, P. falciparum, P. ovale (including P. ovale wallikeri) and/or P. malariae.', 'In all the seven experimental repeats, FP-PCR successfully detected single-species infection for all the four species, with the detection limit reaching or close to 1 parasite/µl blood. For mixed infections with 2-4 species at different densities with the highest being 100 times of the lowest, FP-PCR identified all the species in each combination in 57 out of 84 tests. Further, in 10 dried blood samples on filter paper from healthy subjects, no FP-PCR amplification was found, except weak formation of dimers.
answer:
Does [ Single-tube Single-run Multiplex PCR detect Mixed Samples with Four Species of Plasmodium ]?


question:
Cyclovirobuxinum D (CVB-D), an alkaloid isolated from the Chinese medicinal plant Buxus microphylla, has been found to be effective to treat cardiac insufficiency, arrhythmias and coronary heart disease. In the present study, we investigated the effects of CVB-D on the inflammatory responses in lipopolysaccharide (LPS)-stimulated murine macrophages in vitro and the underlying mechanisms.', 'Murine macrophage cell line RAW264.7 cells were incubated in the presence of LPS (0.1 μg/mL) for 24 h. The cell viability was measured using MTT assay. The release of NO and cytokines were detected using the Griess test and ELISA, respectively. The mRNA and protein levels were determined using RT-PCR and Western blot, respectively. Reporter gene assays were used to analyze the transcriptional activity of NF-κB.', 'Treatment of RAW264.7 cells with CVB-D (25-300 μmol/L) did not affect the cell viability. Pretreatment with CVB-D (50, 100 and 200 μmol/L) concentration-dependently decreased NO release and iNOS expression in LPS-treated RAW264.7 cells (its IC50 value in inhibition of NO production was 144 μmol/L). CVB-D also concentration-dependently inhibited the secretion and mRNA expression of IL-1β and IL-6 in LPS-treated RAW264.7 cells. Furthermore, CVB-D remarkably inhibited the phosphorylation of STAT1 and STAT3, as well as JAK2 in LPS-treated RAW264.7 cells, but did not affect the activation of NF-κB and MAPKs pathways. Pretreatment with the JAK2 specific inhibitor AG490 (30 μmol/L) produced similar effects on NO release and iNOS expression in LPS-treated RAW264.7 cells.
answer:
Does cyclovirobuxinum D suppress lipopolysaccharide-induced inflammatory responses in murine macrophages in vitro by blocking JAK-STAT signaling pathway?


question:
To determine whether a common peer assessment instrument can assess competencies across internal medicine, pediatrics, and psychiatry specialties.', "A common 36 item peer survey assessed psychiatry (n = 101), pediatrics (n = 100), and internal medicine (n = 103) specialists. Cronbach's alpha and generalizability analysis were used to assess reliability and factor analysis to address validity.", "A total of 2,306 (94.8% response rate) surveys were analyzed. The Cronbach's alpha coefficient was.98. The generalizabililty coefficient (mean of 7.6 raters) produced an Ep(2) =.83. Four factors emerged with a similar pattern of relative importance for pediatricians and internal medicine specialists whose first factor was patient management. Communication was the first factor for psychiatrists.
answer:

Do an examination of the appropriateness of using a common peer assessment instrument to assess physician skills across specialties?
