A lateral flow strip biosensor for fast, sensitive, low-cost and on-site detection of kanamycin was developed by using kanamycin-specific aptamer-modified gold nanoparticles (AuNPs-apt) as a probe and oligonucleotide DNA1-modified silver nanoparticles (AgNPs-DNA1) as a signal amplification element. Through the complementary sequences of DNA1 and the aptamer, the AgNP-DNA1-apt-AuNPs complex can be formed and further captured on the test zone of the strip, where a capture probe DNA2 complementary to the 3'-terminal of DNA1 was immobilized...

Enological tannins are widely used in the winemaking process either to improve different wine characteristics (color stability, among others) or to compensate for low tannin levels. In this work, the influence of the addition of two different enological tannins, mainly composed of hydrolysable (ellagitannins) and condensed tannins, on the evolution of color and pigment composition of two different types of model systems containing the five main grape anthocyanins was studied. In addition, the effect of the addition of an enological tannin on the color and pigment composition of red wines made from Vitis vinifera L...

The automatic detection of diabetic retinopathy is of vital importance, as it is the main cause of irreversible vision loss in the working-age population in the developed world. The early detection of diabetic retinopathy occurrence can be very helpful for clinical treatment; although several different feature extraction approaches have been proposed, the classification task for retinal images is still tedious even for those trained clinicians. Recently, deep convolutional neural networks have manifested superior performance in image classification compared to previous handcrafted feature-based image classification methods...

Adult-onset Still's disease (AOSD) is an inflammatory disorder characterized by recurrent fevers, arthralgia, leukocytosis, and a salmon-colored rash. Diagnosis is made based on the Yamaguchi criteria. Various cardiac and pulmonary manifestations have been described in association with AOSD, including acute respiratory distress syndrome (ARDS) and pulmonary arterial hypertension (PAH). We describe the first case of both PAH and ARDS in a patient with AOSD who, despite aggressive therapy, declined rapidly and ultimately died...

BACKGROUND: Due to the liberalization of the European sugar market the pressure to improve factory utilization is growing. Currently beet and cane as sucrose sources are produced in isolation, according to geography. Co-production of sugar from beet and cane origin in one stream is a promising option. However, knowledge base for production sugar is practically non-existing. This manuscript is part of our contribution to this field and specifically addresses effects of raw material quality...

Liver lesions are often incidentally detected on ultrasound examination and may be incompletely characterized, requiring further imaging. Contrast-enhanced ultrasound (CEUS) was recently approved by the Food and Drug Administration in the United States for liver lesion characterization. CEUS has the ability to characterize focal liver lesions and has been shown to be superior to color Doppler and power Doppler ultrasound in the detection of tumor vascularity. Differentiating benign from malignant liver lesions is essential to characterizing liver lesions...

Naturally occurring nanoparticles may be present in food. In this paper we report the discovery of fluorescent nanoparticles (FNs) in Chinese mature vinegar. The physicochemical properties of these FNs were investigated. The FNs were shown to emit bright blue fluorescence under the irradiation of ultraviolet light, with a fluorescence quantum yield of 5.71%. They are highly soluble in aqueous solution, and exhibit excitation-dependent emission behavior. TEM characterization showed that the average size of FNs is about 1...

Preserving the highly appreciated natural freshness of Aloreña de Málaga table olives and preventing their progressive darkening during processing is a major challenge. In this work, heat-shocked (60°C, 5 min) fruits were processed according to the three denominations referred to in the Protected Designation of Origen (cured, fresh green, and traditional) and their characteristics compared with those that followed the habitual industrial process (controls). The results revealed that the effects of the heat treatment on the evolution of pH, titratable acidity, salt, sugar, organic acid, ethanol content, texture, and color of fruits as well as on microbial populations (yeasts and lactic acid bacteria) were slight in the case of the fresh green and cured presentations...

Montastraea cavernosa is a common coral in the Caribbean basin found in several color morphs. To investigate the causes for brown and orange morphs we undertook a genomics approach on corals collected at the same time and depth in the Bahamas. The coral holobiont includes the host, symbiotic dinoflagellates (Symbiodinium spp.), and a diverse microbiome. While the coral host showed significant genetic differentiation between color morphs both the composition of the Symbiodinium spp. communities and the prokaryotic communities did not...

BACKGROUND: Lily is an economically important plant, with leaves and bulbs consisting of overlapping scales, large ornamental flowers and a very large genome. Although it is recognized that flowers and bulb scales are modified leaves, very little is known about the genetic control and biochemical differentiation underlying lily organogenesis and development. Here we examined the differentially expressed genes in flower, leaf and scale of lily, using RNA-sequencing, and identified organ-specific genes, including transcription factors, genes involved in photosynthesis in leaves, carbohydrate metabolism in bulb scales and scent and color production in flowers...

Giant Cell Arteritis (GCA) and Takayasu's arteritis (TA) are large vessel vasculitis (LVV) primarily affecting the aorta and its major branches, mainly differentiated by the onset age (>50 years GCA and <40 years TA). In addition, temporal artery involvement and polymyalgia rheumatic are typical features of GCA, but not TA. Imaging techniques are required to secure the diagnosis of large-vessel vasculitides, and to monitor the disease course. Both morphological and metabolic imaging are involved. Morphological imaging is represented mainly by Computerized Tomography (CT), CT angiography, Magnetic Resonance (MR), MR angiography, Color-Doppler Sonography (CDS) and high-resolution CDS...

Weevils (Curculionoidea) comprise one of the most diverse groups of organisms on earth. There is hardly a vascular plant or plant part without its own species of weevil feeding on it and weevil species diversity is greater than the number of fishes, birds, reptiles, amphibians and mammals combined. Here, we employ ultraconserved elements (UCEs) designed for beetles and a novel partitioning strategy of loci to help resolve phylogenetic relationships within the radiation of Australasian smurf-weevils (Eupholini)...

The aim of this study was to evaluate the effect of Syzygium cumini leaves (SCL) in laying hens diets on productive performance, egg quality and lipid oxidation of yolk. A total of 108 Hysex White laying hens were distributed in a completely randomized design with three treatments and six replicates of six birds each. The treatments consisted of SCL inclusion at dietary levels of 0, 5 and 10 g/kg. There was no significant effect of SCL inclusion on feed intake, laying percentage, weight and egg mass, feed conversion ratio, Haugh units, specific gravity, percentage of yolk, albumen and egg shells and shell thickness...

Nevus lipomatosus cutaneous superficialis is a rare benign hamartomatous skin tumor characterized by dermal deposition of mature adipose tissue. Two clinical forms have been described (classical and solitary types). We describe a case of nevus lipomatosus cutaneous superficialis with a 13-year history of growth in a young woman who had a solitary skin-colored tumoral mass on the right buttock. Histopathological findings were typical and confirmed the diagnosis. In this case, the lesion was a skin-colored isolated mass, as described in the solitary type, but its localization and age of appearance were compatible with the classical type...

Our visual brain makes use of recent experience to interact with the visual world, and efficiently select relevant information. This is exemplified by speeded search when target- and distractor features repeat across trials versus when they switch, a phenomenon referred to as intertrial priming. Here, we present fAIM, a computational model that demonstrates how priming can be explained by a simple feature-weighting mechanism integrated into an established model of bottom-up vision. In fAIM, such modulations in feature gains are widespread and not just restricted to one or a few features...

As gaming culture continues to marginalize women and people of color, other gamers are also highlighting the inequalities they face within digital gaming communities. While heterosexism and homophobia are commonplace within gaming culture, little is known about the actual experiences of "gaymers" and even less about "gaymers" of color. As such, this article seeks to explore lesbians of color and their experiences "gayming" out and online. Exploring identity development, community building, and connectivity via social networking, the women within this study articulate what it means to be lesbian online and how this impacts their physical and digital experiences...
