Marco Alessandrini, Sharon S Kappala, Michael S Pepper
Acute myeloid leukemia is characterized by the proliferation and accumulation of immature hematopoietic cells of the myeloid lineage in the bone marrow. The disease is typified by diverse genetic abnormalities and marked heterogeneity both with regard to response to treatment and survival. The AMLprofiler is a qualitative in vitro diagnostic microarray developed by SkylineDx for use with Affymetrix technology. The AMLprofiler makes use of RNA chemistry and incorporates seven separate assays based on three different technologies-cytogenetics, mutation, and expression analysis-to predict post-therapy survival rates in patients with acute myeloid leukemia...

Both diet and host phylogeny shape the gut microbial community, and separating out the effects of these variables can be challenging. In this study, high-throughput sequencing was used to evaluate the impact of diet and phylogeny on the gut microbiota of nine colobine monkey species (N = 64 individuals). Colobines are leaf-eating monkeys that fare poorly in captivity-often exhibiting gastrointestinal (GI) problems. This study included eight Asian colobines (Rhinopithecus brelichi, Rhinopithecus roxellana, Rhinopithecus bieti, Pygathrix nemaeus, Nasalis larvatus, Trachypithecus francoisi, Trachypithecus auratus, and Trachypithecus vetulus) and one African colobine (Colobus guereza)...

Kathrin Schmidt, Dieter Spiteller
Streptomyces violaceoruber grown in co-culture with Streptomyces aburaviensis produces an about 17-fold higher volume of droplets on its aerial mycelium than in single-culture. Physical separation of the Streptomyces strains by either a plastic barrier or by a dialysis membrane, which allowed communication only by the exchange of volatile compounds or diffusible compounds in the medium, respectively, still resulted in enhanced droplet formation. The application of molecular sieves to bioassays resulted in the attenuation of the droplet-inducing effect of S...

Gounipalli Veeranagamallaiah, Chinta Sudhakar
Polyamines are polycationic nitrogenous compounds that accumulate in plants exposed to abiotic stresses. In higher animals, they influence gene expression, brain development, and nerve growth and regeneration. Because of their known roles in plant stress responses, quantitative determination of polyamines is very important. Polyamines in their native form cannot be detected by optical and/or electrochemical methods as they do not show any structural features, and hence derivatization of polyamines is essential to make them to produce either chromophores or fluorescence...

In response to oxidative stress the biosynthesis of the ROS scavenger, glutathione is induced. This requires the induction of the sulfate reduction pathway for an adequate supply of cysteine, the precursor for glutathione. Cysteine also acts as the sulfur donor for the sulfuration of the molybdenum cofactor, crucial for the last step of ABA biosynthesis. Sulfate and sulfite are, respectively, the precursor and intermediate for cysteine biosynthesis and there is evidence for stress-induced sulfate uptake and further downstream, enhanced sulfite generation by 5'-phosphosulfate (APS) reductase (APR, EC 1...

Global proteome profiling is a direct representation of the protein set in an organism, organ, tissues, or an organelle. One of the main objectives of proteomic analysis is the comparison and relative quantitation of proteins under a defined set of conditions. Two-dimensional gel electrophoresis (2-DE) has gained prominence over the last 4 decades for successfully aiding differential proteomics, providing visual confirmation of changes in protein abundance, which otherwise cannot be predicted from genome analysis...

Our goal was to identify the specific contribution of fear of falling (FoF) and falls with quantitative gait impairments and cognition capabilities in multiple sclerosis (MS) patients. Patients were separated into four individual subgroups as to the presence of FoF and falls (i.e., fearless/non-fallers, fearless/fallers, FoF/non-fallers and FoF/fallers). The Falls Efficacy Scale International questionnaire was used to assess the level of concern of falling. Participants were defined as "fallers" and "non-fallers" based on their fall history...

Community structure of bacteria present in arsenic contaminated agricultural soil was studied with qPCR (quantitative PCR) and DGGE (Denaturing Gradient Gel Electrophoresis) as an indicator of extreme stresses. Copy number of six common bacterial taxa (Acidobacteria, Actinobacteria, α-, β- and γ-Proteobacteria, Firmicutes) was calculated using group specific primers of 16S rDNA. It revealed that soil contaminated with low concentration of arsenic was dominated by both Actinobacteria and Proteobacteria but a shift towards Proteobacteria was observed with increasing arsenic concentration, and number of Actinobacteria eventually decreases...

Designing effective public health strategies to prevent adverse health effect of hot weather is crucial in the context of global warming. In Switzerland, the 2003 heat have caused an estimated 7% increase in all-cause mortality. As a consequence, the Swiss Federal Office of Public Health developed an information campaign to raise public awareness on heat threats. For a better understanding on how hot weather affects daily mortality in Switzerland, we assessed the effect of heat on daily mortality in eight Swiss cities and population subgroups from 1995 to 2013 using different temperature metrics (daily mean (Tmean), maximum (Tmax), minimum (Tmin) and maximum apparent temperature (Tappmax)), and aimed to evaluate variations of the heat effect after 2003 (1995-2002 versus 2004-2013)...

Compared to other forensic comparative sciences, studies of the efficacy of the likelihood ratio (LR) framework in forensic authorship analysis are lagging. An experiment is described concerning the estimation of strength of linguistic text evidence within that framework. The LRs were estimated by trialling three different procedures: one is based on the multivariate kernel density (MVKD) formula, with each group of messages being modelled as a vector of authorship attribution features; the other two involve N-grams based on word tokens and characters, respectively...

A series of porous polymers was synthesized by a suspension polymerization of divinylbenzene (DVB) and ethylene glycol dimethyl acrylate (EGDMA), which was further functionalized with polyethyleneimine (PEI) for CO2 capture. The results showed that the synthesized DVB and EGDMA (DE) copolymers were an effective support for loading PEI because of its larger pore size and specific surfaces area. It was found that DE (30, 10) loaded with 30wt% PEI exhibited a higher CO2 adsorption amount of 3.28mmol/g at 25°C under dry condition...

A series of novel visible-light-driven Ag/Ag3PO4/WO3 (AAPW) Z-scheme heterostructures were fabricated using a facile deposition-precipitation method followed by photo-reduction without adding any surfactant. To explore more deeply about the photocatalytic activity of AAPW nanocomposites under neutral and strongly acidic/alkaline conditions, we investigated their photocatalytic rhodamine B (RhB) efficiency at different pH value that was controlled by adding HNO3 or NaOH aqueous solution. It was found that as-prepared AAPW photocatalysts showed enhanced photocatalytic RhB efficiency under neutral and even strongly acidic/alkaline environment...

Fluidized-bed Fenton coupled with ceramic membrane separation to treat the flax secondary effluent was investigated. The operating variables, including initial pH, dosage of H2O2 and Fe(0), air flow rate, TMP and pore size, were optimized. The distributions of DOMs in the treatment process were analyzed. Under the optimum condition (600mgL(-1)H2O2, 1.4gL(-1) Fe(0), pH=3, 300Lh(-1) air flow rate and 15psi TMP), the highest TOC and color removal efficiencies were 84% and 94% in the coupled reactor with 100nm ceramic membrane, reducing 39% of total iron with similar removal efficiency compared with Fluidized-bed Fenton...

REVIEW
Hye Sup Yun, Chian Kwon
To defend against extracellular pathogens, plants primarily depend on cell-autonomous innate immunity due to the lack of the circulatory immune system including mobile immune cells. To extracellularly restrict or kill the pathogens, plant cells dump out antimicrobials. However, since antimicrobials are also toxic to plant cells themselves, they have to be safely delivered to the target sites in a separate vesicular compartment. In addition, because immune responses often requires energy otherwise used for the other metabolic processes, it is very important to properly control the duration and strength of immune responses depending on pathogen types...

A neural signature of asymptomatic preclinical Alzheimer's disease (AD) is disrupted connectivity between brain regions; however, its underlying mechanisms remain unknown. Here, we tested whether a preclinical pathologic feature, tau aggregation in the entorhinal cortex (EC) is sufficient to disrupt the coordination of local field potentials (LFPs) between its efferent regions. P301L-mutant human tau or green fluorescent protein (GFP) was virally overexpressed in the EC of adult rats. LFPs were recorded from the dorsal hippocampus and prelimbic medial prefrontal cortex while the rats underwent trace eyeblink conditioning where they learned to associate 2 stimuli separated by a short time interval...
