Micropropagated plants experience significant stress from rapid water loss when they are transferred from an in vitro culture to either greenhouse or field conditions. This is caused both by inefficient stomatal control of transpiration and the change to a higher light intensity and lower humidity. Understanding the physiological, vascular and biomechanical processes that allow micropropagated plants to modify their phenotype in response to environmental conditions can help to improve both field performance and plant survival...

Brian Machovina, Kenneth J Feeley
Reducing meat consumption by humans and shifting to more efficient plant and animal protein sources could potentially free up large areas of pasture and feedcrop agricultural land for restoration or conversion to low-input high-diversity (LIHD) grasslands. LIHD grasslands improve biodiversity, carbon sequestration, erosion control, water storage, while also providing opportunities to produce biofuels. We examined the potential of converting pastures globally, and animal feedstock agricultural lands in the USA and Brazil, to LIHD biomass sources and the capacity of these systems to meet national energy demands via (1) cellulosic ethanol and (2) integrated gasification and combined cycle technology with Fischer-Tropsch hydrocarbon synthesis (IGCC-FT) processing...

Peng Zheng, Nianqiang Wu
Graphene oxide and graphene quantum dots are attractive fluorophores, which are inexpensive, non-toxic, photo-stable, water-soluble, biocompatible and environmentally friendly. They find extensive applications in fluorescent biosensors and chemi-sensors, in which they either serve as fluorophores or quenchers. As fluorophores, they display the tunable photoluminescence emission and the "Giant Red-Edge Effect". As quenchers, they exhibit a remarkable quenching efficiency via either electron transfer or Förster resonance energy transfer (FRET) process...

Obesity is one of the most serious global public health challenges of the 21st century. The adjustment of gut microbiota is often recommended as an efficient strategy to treat obesity. This modulation of gut microbiota can be performed by many methods, including dietary intervention, antibiotic application, the use of prebiotics and probiotics, bariatric surgery and faecal microbiota transplantation. In most cases, positive effects have been observed in response to treatment, but invalid and even contrary effects have also been observed in some cases due to factors that are unrelated to intervention methods, such as genetic factors, patient age or gender, environmental microbiota, climate, geography and lifestyle...

Sandra Varga, Minna-Maarit Kytöviita
In gynodioecious plants, females are expected to produce more or better seeds than hermaphrodites in order to be maintained within the same population. Even though rarely measured, higher seed production can be achieved through differences in physiology. In this work, we measured sexual dimorphism in several physiological traits in the gynodioecious plant Geranium sylvaticum. Photosynthetic rate, stomatal conductivity, transpiration rate, water use efficiency and isotopic signatures were measured in plants growing in two habitats differing in light availability...

Factor H-binding protein (fHbp) is an important meningococcal vaccine antigen. Native outer membrane vesicles with over-expressed fHbp (NOMV OE fHbp) have been shown to induce antibodies with broader functional activity than recombinant fHbp (rfHbp). Improved understanding of this broad coverage would facilitate rational vaccine design. We performed a pair-wise analysis of 48 surface-exposed amino acids involved in interacting with factor H, among 383 fHbp variant group 1 sequences. We generated isogenic NOMV-producing meningococcal strains from an African serogroup W isolate, each over-expressing one of four fHbp variant group 1 sequences (ID 1, 5, 9, or 74), including those most common among invasive African meningococcal isolates...

BACKGROUND: After traumatic brain injury (TBI), the ability of cerebral vessels to appropriately react to changes in arterial blood pressure (pressure reactivity) is impaired, leaving patients vulnerable to cerebral hypo- or hyperperfusion. Although, the traditional pressure reactivity index (PRx) has demonstrated that impaired pressure reactivity is associated with poor patient outcome, PRx is sometimes erratic and may not be reliable in various clinical circumstances. Here, we introduce a more robust transform-based wavelet pressure reactivity index (wPRx) and compare its performance with the widely used traditional PRx across 3 areas: its stability and reliability in time, its ability to give an optimal cerebral perfusion pressure (CPPopt) recommendation, and its relationship with patient outcome...

Several federal agencies have recently noted that the United States is in the midst of an unprecedented "opioid epidemic," with an increasing number of opioid-related overdoses and deaths. Providers currently face 3 population-level, public health challenges in providing optimal perioperative pain care: (1) the continued lack of overall improvement in the excessive incidence of inadequately treated postoperative pain, (2) minimizing or preventing postoperative opioid-related side effects, and (3) addressing current opioid prescribing patterns, and the accompanying problematic surge in prescription opioid diversion, misuse, abuse, addiction, and overdose...

BACKGROUND: Observation units (OUs) may be an efficient and effective setting to diagnose and risk stratify patients with coronary ischemia and myocardial infarction (MI). Given improved cardiac troponin I (cTnI) assays and expanded utilization of OUs, it is not uncommon for patients with mildly elevated cTnI to be evaluated in OUs. We investigated the serial cTnI results in OU patients to determine whether absolute or relative cTnI changes were useful for the diagnosis of MI. METHODS: This was a retrospective study of 260 patients placed in the OU from a single center in 2007, with an initial cTnI in the indeterminate range of 0...

Charles J Dorman, Marina M Bogue
Site-specific recombination is employed widely in bacteria and bacteriophage as a basis for genetic switching events that control phenotypic variation. It plays a vital role in the life cycles of phages and in the replication cycles of chromosomes and plasmids in bacteria. Site-specific recombinases drive these processes using very short segments of identical (or nearly identical) DNA sequences. In some cases, the efficiencies of the recombination reactions are modulated by the topological state of the participating DNA sequences and by the availability of accessory proteins that shape the DNA...

OBJECTIVES: This study examined how different quantifications of pain (average vs. day-to-day inconsistency) are related to sleep in older adults beyond known predictors. METHODS: Baseline measures from the Active Adult Mentoring Project were used for secondary analyses. Participants included 82 adults in mid- to late-life. Depression was assessed with the BDI-II. Pain intensity was assessed over seven days on a 11-point Likert-scale, while sleep efficiency (SE), total sleep time (TST), and total wake time (TWT) were assessed using a self-report diary...

Crystallization water plays an important role for the self-organization of oligomer chains in conducting polyaniline - emeraldine. In order to quantify the interaction between the emeraldine salt and such a water, models containing a tetramer in bipolaronic or polaronic form, chloride counterions and an explicit water molecule are used. Different initial positions of water with respect to the oligomer chain - tangential and vertical, are considered. Various media are simulated by introducing implicit solvent continuum of decreasing polarity...

Enzymes normally lose their activities under extreme conditions due to the dissociation of their active tertiary structure. If an enzyme could maintain its catalytic activity under non physiological or denaturing conditions, it might be used in more applications in the pharmaceutical and chemical industries. Recently, we reported a coiled-coil six-helical bundle (6HB) structure as a scaffold for designing artificial hydrolytic enzymes. Here, intermolecular isopeptide bonds were incorporated to enhance the stability and activity of such biomolecules under denaturing conditions...

This study examined recent stress exposure and effortful coping effects on salivary cortisol (sC) response patterns in preadolescent boys and girls (N = 121, Mage  = 10.60 years). Children were exposed to the Trier Social Stress Test (TSST) and one of two randomly assigned, post-TSST coping conditions: distraction and avoidance. Piecewise growth multilevel modeling did not link children's recent stressful life events or hair cortisol (hC) levels to sC reactivity, though each interacted with coping condition to predict sC recovery patterns...

BACKGROUND: Aedes aegypti is a major mosquito vector of arboviruses, including dengue, chikungunya and Zika. In 2005, Ae. aegypti was identified for the first time in Madeira Island. Despite an initial insecticide-based vector control program, the species expanded throughout the Southern coast of the island, suggesting the presence of insecticide resistance. Here, we characterized the insecticide resistance status and the underlying mechanisms of two populations of Ae. aegypti from Madeira Island, Funchal and Paúl do Mar...

Broad Learning System (BLS) that aims to offer an alternative way of learning in deep structure is proposed in this paper. Deep structure and learning suffer from a time-consuming training process because of a large number of connecting parameters in filters and layers. Moreover, it encounters a complete retraining process if the structure is not sufficient to model the system. The BLS is established in the form of a flat network, where the original inputs are transferred and placed as "mapped features" in feature nodes and the structure is expanded in wide sense in the "enhancement nodes...
