This work demonstrates the development of a gold screen-printed electrode (Au-SPE)-based biosensor modified with a molecularly imprinted polymer and amplified using antibody-conjugated nano-liposomes. The developed biosensor was utilized for dual determination of epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) as cancer biomarkers. To prepare this biosensor, Au-SPE was modified with 3,3'-dithiodipropionic acid di(N-hydroxysuccinimide ester) via self-assembly method and then the target proteins (EGFR and VEGF) were covalently attached to the modified SPE...

Biochar effect on the potential mobility of dibutyl phthalate (DBP), cadmium (Cd), and lead (Pb) in co-contaminated soils is not well investigated. A laboratory leaching study was conducted to evaluate the effect of biochars derived from bamboo (BB) and pig (PB) on the leachability of DBP, Cd, and Pb through soil columns packed with two soils with low or high organic carbon content (LOC; 0.35% C: HOC; 2.24% C) and spiked with DBP, Cd, and Pb. Application of PB to the LOC soil significantly (P < 0.05) reduced the leaching loss by up to 88% for DBP, 38% for Cd, and 71% for Pb, whereas its impact was insignificant in the HOC soil...

Manganese (Mn) is an essential micro-nutrient for plants, but flooded rice fields can accumulate high levels of Mn2+ leading to Mn toxicity. Here, we present a genome-wide association study (GWAS) to identify candidate loci conferring Mn toxicity tolerance in rice (Oryza sativa L.). A diversity panel of 288 genotypes was grown in hydroponic solutions in a greenhouse under optimal and toxic Mn concentrations. We applied a Mn toxicity treatment (5 ppm Mn2+, 3 weeks) at twelve days after transplanting. Mn toxicity caused moderate damage in rice in terms of biomass loss and symptom formation despite extremely high shoot Mn concentrations ranging from 2...

BACKGROUND AND OBJECTIVES: Ample research in obsessive-compulsive disorder (OCD) reveals a moderate degree of underperformance on various neuropsychological tasks. Less is known about neuropsychological function in subclinical obsessive-compulsive (OC) samples. Most analogue OCD studies did not use a comprehensive neuropsychological battery and none utilized a fully computerized battery. To fill this gap in the literature, the present study aimed at assessing cognitive functions in a subclinical OC sample using a validated computerized neuropsychological battery...

Mindfulness-based intervention has become increasingly popular to address disinhibited eating in obesity and type 2 diabetes (T2D). Theoretically, present-moment attention promotes the ability to recognize and respond to internal hunger cues and to differentiate physiological hunger from other stimuli. Yet, there is limited research describing the relationship of mindfulness with disinhibited eating patterns in adolescents. In this study, we evaluated the relationship of dispositional mindfulness to laboratory eating in 107 adolescent (12-17 years) girls at risk for T2D...

Emotion regulation difficulties influence the etiology and maintenance of binge eating and eating disorders, but differential associations between emotion dysregulation and objective binge eating (OBE) components have not been examined. We compared emotion dysregulation dimensions in women with OBEs (n = 27), overeating only (n = 25), loss of control (LOC) only (n = 32), or no pathological eating (n = 137). Women with OBEs had significantly more difficulty with overall emotion dysregulation, access to strategies, and impulse control when upset than other groups...

OBJECTIVES: To quantify tear elimination rate (ER) underneath silicone hydrogel (Si-Hy) and scleral gas permeable (GP) contact lenses (CLs). METHODS: Subjects successfully using either well-fitting soft Si-Hy CLs or scleral GP CLs were recruited. Most scleral GP CL wearers had irregular corneas (e.g., keratoconus). An objective fluorometer measured decay of fluorescein isothiocyanate dextran dye signal (70 kD MW) from which the tear ER in %/min was calculated. For GP scleral lenses, the ER was determined for both the initial settling period and the 30- to 60-min period, and without lenses...

BACKGROUND: Rice is a major source of food, particularly for the growing Asian population; hence, the utilization of genes for enhancing its yield potential is important for ensuring food security. Earlier, we have mapped a major quantitative trait loci (QTL) for the grain number per panicle, qGN4.1, using biparental recombinant inbred line (RIL) populations involving a new plant type Indica rice genotype Pusa 1266. Later, three independent studies have confirmed the presence of a major QTL for spikelet number by three different names (SPIKE, GPS and LSCHL4) in the same chromosomal region, and have implicated the overexpression of Nal1 gene as the causal factor for high spikelet number...

Anther cuticle and pollen exine are two elaborated lipid-soluble barriers protecting pollen grains from environmental and biological stresses. However, less is known about the mechanisms underlying the synthesis of these lipidic polymers. Here, we identified a no-pollen male-sterility mutant cyp703a3-3 from indica restorer line Zhonghui 8015 (Zh8015) mutant library treated with 60Coγ-ray radiation. Histological analysis indicated that cyp703a3-3 underwent abnormal tapetal cells development, produced few orbicules and secreted less sporopollenin precursors to anther locule, as well as cutin monomers on anther...

We have investigated concentrated suspensions of polydisperse hard spheres and have determined the dynamics and sizes of individual particles using confocal microscopy. With increasing concentration, the dynamics of the small and large particles start to differ. The large particles exhibit slower dynamics and stronger localization. Moreover, as the particle size increases, the local volume fraction ϕ_{loc} also increases. In the glass state, the localization length significantly decreases beyond ϕ_{loc}≈0...
