The Impact of Storage Conditions on Stool Smellprints as Assessed by an Electronic Nose.

Necrotizing enterocolitis (NEC) is a devastating disease of the neonatal gastrointestinal tract. Volatile organic compounds (VOCs), odoriferous compounds released as a byproduct of bacterial metabolism, can be used as a proxy for gut health. We hypothesized that patients with NEC would have different microbial profiles and elicit different VOC signatures as assessed by gas chromatography/mass spectrometry (GC/MS) or an electronic nose compared to controls.

Real time-PCR a diagnostic tool for reporting copy number variation and relative gene-expression changes in pediatric B-cell acute lymphoblastic leukemia-a pilot study.

Real time-polymerase chain reaction (RT-PCR) is used routinely in clinical practice as a cost-effective method for molecular diagnostics. Research in pediatric B-cell Acute Lymphoblastic Leukemia (ped B-ALL) suggests that apart from cytogenetics and clinical features, there is a need to include Copy number variation (CNV) in select genes at diagnosis, for upfront stratification of patients. Using ped B-ALL as a model, we have developed a RT-PCR-based iterative probability scoring method for reporting CNVs, and relative gene-expression changes.

Determining chlorophyll-a thresholds for characterizing algal bloom conditions: An ocean colour remote sensing approach.

The Indian coast has been experiencing an increase in algal bloom events over the decades. Owing to the regional and seasonal dynamics of algal biomass (proxy: chlorophyll-a, hereafter chl-a), a multitude of thresholds of chl-a has been defined for different parts of the global seas to determine algal bloom conditions. However, no such clear definition is given for the Indian coastal waters.

Ethanol release patterns and captures of Xylosandrus spp. (Coleoptera: Curculionidae) in ornamental nursery.

Xylosandrus crassiusculus Motschulsky and Xylosandrus germanus Blandford are serious ambrosia beetle pests in ornamental nurseries. Three ethanol baits, AgBio low release (LR), AgBio high release (HR), and Trécé are commercially available for use in bottle traps to determine flight activity of adult Xylosandrus spp. However, release patterns of ethanol from these baits under varying temperatures and captures of Xylosandrus spp.
