Metrics to quantify child growth vary across studies of the developmental origins of health and disease. We conducted a scoping review of child growth studies in which length/height, weight or body mass index (BMI) was measured at ≥ 2 time points. From a 10% random sample of eligible studies published between Jan 2010-Jun 2016, and all eligible studies from Oct 2015-June 2016, we classified growth metrics based on author-assigned labels (e.g., 'weight gain') and a 'content signature', a numeric code that summarized the metric's conceptual and statistical properties...

EGFR-based targeted therapies have shown limited success in smokers. Identification of alternate signaling mechanism(s) leading to TKI resistance in smokers is critically important. We observed increased resistance to erlotinib in H358 NSCLC (non-small cell lung carcinoma) cells chronically exposed to cigarette smoke (H358-S) compared to parental cells. SILAC-based mass-spectrometry approach was used to study altered signaling in H358-S cell line. Importantly, among the top phosphosites in H358-S cells we observed hyperphosphorylation of EGFR (Y1197) and non-receptor tyrosine kinase FAK (Y576/577)...

Kinematic redundancy of the human body provides abundant movement patterns to accomplish the same motor goals (motor equivalence). Compensatory movement patterns such as excessive trunk displacement in stroke subjects during reaching can be viewed as a consequence of the motor equivalent process to accomplish a task despite limited available ranges in some joints. However, despite compensations, the ability to adapt reaching performance when perturbations occur may still be limited when condition-specific changes of joint angles are required...

T cells reacting to self-components can promote tissue damage when escaping tolerogenic control mechanisms which may result in autoimmune disease. The current treatments for these disorders are not antigen (Ag) specific and can compromise host immunity through chronic suppression. We have previously demonstrated that co-administration of encapsulated or free Ag with tolerogenic nanoparticles (tNPs) comprised of biodegradable polymers that encapsulate rapamycin are capable of inhibiting Ag-specific transgenic T cell proliferation and inducing Ag-specific regulatory T cells (Tregs)...

The crucial role of chemosensor for the immediate recognition of environment pollutant motivates the researchers to develop variety of sensing protocols. Of various chemosensory protocols, the colour change observed by the naked eye is considered to be a conceivable and on-site way to indicate the presence of an analyte. We herein report a colourimetric and commercially available absorption probe, sinapic acid (SA) that is completely ready to use for "on-site" visual determination of copper ions. The molecule, SA is well-known phenolic acid, often utilized for its antibacterial activity...

Heart is a dynamic organ that undergoes remodeling in response to both physiological and pathological stimuli. One of the fundamental cellular processes that facilitates changes in the size and shape of this muscular organ is the protein synthesis. Traditionally changes in cardiac protein synthesis levels were measured by radiolabeled tracers. However, these methods are often cumbersome and suffer from radioactive risk. Recently a nonradioactive method for detecting protein synthesis under in vitro conditions called the Surface Sensing of Translation (SUnSET) was described in cell lines of mouse dendrites and T cells...

Residual solid and liquid streams from the one-pot CRUDE (Conversion of Raw and Untreated Disposal into Ethanol) process were treated with two separate biochemical routes for renewable energy transformation. The solid residual stream was subjected to thermophilic anaerobic digestion (TAD), which produced 95 ± 7 L methane kg-1 volatile solid with an overall energy efficiency of 12.9 ± 1.7%. A methanotroph, Methyloferula sp., was deployed for oxidation of mixed TAD biogas into methanol. The residual liquid stream from CRUDE process was used in a Microbial Fuel Cell (MFC) to produce electricity...

INTRODUCTION: Translocation of phosphatidylserine from the inner leaflet to the outer leaflet of the endothelial membrane via phospholipid scramblase-1 (PLSCR1) is an apoptotic signal responsible for the loss of endothelial barrier integrity after ischemia-reperfusion injury. We hypothesized that inhibiting phosphatidylserine expression on endothelial cells would attenuate ischemia-reperfusion (IRI) induced increases in hydraulic permeability (Lp). METHODS: Mesenteric hydraulic permeability (Lp) was measured in rat post-capillary mesenteric venules subjected to IRI via superior mesenteric artery (SMA) occlusion (45 minutes) and release (300 minutes) in conjunction with several inhibitors of phosphatidylserine exposure as follows: 1) inhibition of PLSCR1 translocation (DTE - dithioerythritol, n=3), 2) inhibition of PLSCR1 membrane trafficking (2-BP - 2-bromopalmitate, n=3), and 3) inhibition of ion exchange necessary for PLSCR1 function (DIDS - 4,4'-Diisothiocyano-2,2'-stilbenedisulfonic acid, n=3)...

When a soft hydrogel sphere is placed on a rigid hydrophilic substrate, it undergoes arrested spreading by forming an axisymmetric foot near the contact line, while conserving its global spherical shape. In contrast, liquid water (that constitutes greater than 90% of the hydrogel's volume) spreads into a thin film on the same surface. We study systematically this elastowetting of gel spheres on substrates of different surface energies, and find that their contact angle increases as the work of adhesion between the gel and the substrate decreases, as one would observe for drops of pure water - albeit being larger than in the latter case...

The impact of polyploidy on functional diversification of cis-regulatory elements is poorly understood. This is primarily on account of lack of well-defined structure of cis-elements and a universal regulatory code. To the best of our knowledge, this is the first report on characterization of sequence and functional diversification of paralogous and homeologous promoter elements associated with MIR164 from Brassica. The availability of whole genome sequence allowed us to identify and isolate a total of 42 homologous copies of MIR164 from diploid species-Brassica rapa (A-genome), Brassica nigra (B-genome), Brassica oleracea (C-genome), and allopolyploids-Brassica juncea (AB-genome), Brassica carinata (BC-genome) and Brassica napus (AC-genome)...

Neurons are particularly dependent on robust quality control pathways to maintain cellular homeostasis and functionality throughout their extended lifetime. Failure to regulate protein and organelle integrity is linked to devastating neurodegenerative diseases. Autophagy is a lysosomal degradation pathway that maintains homeostasis by recycling damaged or aged cellular components. Autophagy has important functions in development of the nervous system, as well as in neuronal function and survival. In fact, defects in autophagy underlie neurodegeneration in mice and humans...

Glioblastomas (GBMs) are highly aggressive brain tumors with a very grim prognosis even after multi-modal therapeutic regimens. Conventional chemotherapeutic agents frequently lead to drug resistance and result in severe toxicities to non-cancerous tissues. Resveratrol (RES), a natural polyphenol with pleiotropic health benefits, has proven chemopreventive effects in all the stages of cancer including initiation, promotion and progression. However the poor physico-chemical properties of RES severely limit its use as a free drug...

Neonatal cardiomyocytes cultured on flat surfaces are commonly used as a model to study cardiac failure of diverse origin. A major drawback of such a system is that the cardiomyocytes do not exhibit alignment, organization and calcium transients, similar to the native heart. Therefore, there is a need to develop in vitro platforms that recapitulate the cellular microenvironment of the murine heart as organotypic models to study cardiovascular diseases. In this study, we report an engineered platform that mimics cardiac cell organization and function of the heart...
