<div class="abstract-content selected" id="enc-abstract"> <p> Avian metapneumovirus (aMPV) is a viral pathogen that causes respiratory signs and drops in egg production most notably in turkeys but also affects chickens, ducks and other species. Four subgroups (aMPV-A, -B, -C and -D) have been characterized to date, which differ genetically, antigenically and in terms of geographic distribution and host range. Despite the rising awareness towards aMPV, many aspects of its epidemiology are still poorly understood. In this pilot study, a serological survey was carried out to assess the possible circulation of subgroups A, B, …

Even if the critical action takes place in full view, people typically fail to see it due to inattentional blindness (IB). In an eye-tracking experiment, participants watched videos of a new magic…

<div class="abstract-content selected" id="enc-abstract"> <p> Myofibroblasts are critical to processes involved in normal wound healing and during pathological fibrosis. They transdifferentiate from fibroblasts, and in doing so become contractile and capable of secreting large amounts of extracellular matrix proteins. Transforming growth factor-beta (TGFβ) is a key cytokine involved in wound healing and fibrogenesis. TGFβ signaling has long been the subject of experimental therapeutic approaches to inhibit fibrosis in a variety of organ systems. Inhibition of TGFβ can reduce myofibroblast transdifferentiation, contractilit…

<div class="abstract-content selected" id="enc-abstract"> <p> Lodicules are grass-specific floral organs with scale-like shapes that play an important role in flower opening. Because of their position just outside the stamens, lodicules have been suggested as analogous to eudicot petals. Previous molecular genetic studies in maize and rice revealed that identities of lodicule and stamen are specified by members of the AP3-lineage of B-class MADS-box genes, which specify petal and stamen identities in eudicots. This supported the hypothesis that lodicules may be equivalent to eudicot petals. Recent studies in rice, maize, a…

<div class="abstract-content selected" id="enc-abstract"> <p> Petals are typified by their conical epidermal cells that play a predominant role for the attraction and interaction with pollinators. However, cell identities in the petal can be very diverse, with different cell types in subdomains of the petal, in different cell layers, and depending on their adaxial-abaxial or proximo-distal position in the petal. In this mini-review, we give an overview of the main cell types that can be found in the petal and describe some of their functions. We review what is known about the genetic basis for the establishment of these ce…

<div class="abstract-content selected" id="enc-abstract"> <p> Chrysanthemum ( <i> Chrysanthemum morifolium </i> Ramat.) is one of the most important floricultural crops in the world. Although the origin of modern chrysanthemum cultivars is uncertain, several species belonging to the family Asteraceae are considered to have been integrated during the long history of breeding. The flower color of ancestral species is limited to yellow, pink, and white, and is derived from carotenoids, anthocyanins, and the absence of both pigments, respectively. A wide range of flower colors, including purplish-red, oran…

<div class="abstract-content selected" id="enc-abstract"> <p> Fifteen years since the first recognition of clear cell papillary renal cell carcinoma, this distinct renal tumour type is now well accepted as a distinct entity in major classification schemes. It occurs both with and without end-stage renal disease and may be multifocal or bilateral in both scenarios. Recognisable morphological features include clear cells lining branching glands and variable papillary formations with nuclear alignment. Most tumours are small (pT1a) and nucleolar grade 1-2. Immunohistochemistry consistently shows positivity for carbonic anhydr…

<div class="abstract-content selected" id="enc-abstract"> <p> Metagenomics is revolutionizing the field of microbial ecology through techniques that eliminate the prerequisite of culturing. Metagenomic studies of microbial populations in different environments reveal the incredible diversity and adaptive capabilities of these organisms. With the advent of cheaper, high-throughput sequencing technologies, these studies are also producing vast amounts of sequence data. Here, we discuss the different components of a metagenomic study including sample collection, DNA extraction, sequencing, and informatics. We highlight their …

ch you with any such request, as that you shall forfeit your word. Now, what more can I say, only to repeat my advice, and desire you to consult Mr. Riddick in relation to the matter (if you think best) and leave the result with you, and you with the good God, whom I daily desire and implore to sustain, guide, keep, and protect you in the midst of all your trials and isolation. I sent a short letter to you some weeks ago, which I rather suppose must have reached you, in which I told you of the failing condition of our dear old father. He is still failing and rapidly; he cannot remain with us many days, I think (this calls me home); his a…

ch, being put into the mouth produced a kind of coolness. One of the means generally employed, was to put some sea-water into a hat, with which we washed our faces for some time, recurring to it at intervals; we also moistened our hair with it, and held our hands plunged in the water.[29] Misfortune rendered us ingenious, and every one thought of a thousand means to alleviate his sufferings; extenuated by the most cruel privations, the smallest agreeable sensation was to us a supreme happiness; thus we eagerly sought a little empty phial, which one of us possessed, and which had formerly contained essence of roses: as soon as we could get hold o…

<div class="abstract-content selected" id="enc-abstract"> <p> Sexual dimorphism of feather color is typical in mallards, in which drakes exhibit green head feathers, while females show dull head feather color. We showed that more melanosomes deposited in the males' head's feather barbules than females and further form a two-dimensional hexagonal lattice, which conferred the green feather coloration of drakes. Additionally, transcriptome analysis revealed that some essential melanin biosynthesis genes were highly expressed in feather follicles during the development of green feathers, contributing to melanin depos…

<div class="abstract-content selected" id="enc-abstract"> <p> Neuraminidase inhibitors (NAIs) are the gold standard treatment for influenza A virus (IAV). Oseltamivir is mostly used, followed by zanamivir (ZA). NAIs are not readily degraded in conventional wastewater treatment plants and can be detected in aquatic environments. Waterfowl are natural IAV hosts and replicating IAVs could thus be exposed to NAIs in the environment and develop resistance. Avian IAVs form the genetic basis for new human IAVs, and a resistant IAV with pandemic potential poses a serious public health threat, as NAIs constitute a pandemic prepared…

<div class="abstract-content selected" id="enc-abstract"> <p> Animals select resources to maximize fitness but associated costs and benefits are spatially and temporally variable. Differences in wetland management influence resource availability for ducks and mortality risk from duck hunting. The local distribution of the Mallard ( <i> Anas platyrhynchos </i> ) is affected by this resource heterogeneity and variable risk from hunting. Regional conservation strategies primarily focus on how waterfowl distributions are affected by food resources during the nonbreeding season. To test if Mallard resource …

<div class="abstract-content selected" id="enc-abstract"> <p> Mallard ducks are a natural host and reservoir of avian Influenza A viruses. While most influenza strains can replicate in mallards, the virus typically does not cause substantial disease in this host. Mallards are often resistant to disease caused by highly pathogenic avian influenza viruses, while the same strains can cause severe infection in humans, chickens, and even other species of ducks, resulting in systemic spread of the virus and even death. The differences in influenza detection and antiviral effectors responsible for limiting damage in the mallards …
