Recently, growing attention has been paid to the detection of hydrazine (NH2 NH2 ) because of its important roles in industrial chemical and high toxicity to human beings. Herein, we have constructed a new colorimetric and far-red fluorescent probe containing a receptor of 4-bromobutanoate to selectively detect hydrazine. The probe could detect hydrazine quantitatively in the range of 40-500 μM with the detection limit of 2.9 μM. In addition, the probe could monitor hydrazine by the ratiometric method with a large (185 nm) red-shifted absorption spectrum, and the color changes from yellow to blue make it as a 'naked-eye' indicator for hydrazine...

This study was designed to investigate the effects of dietary astaxanthin levels on growth performance, feed utilization, muscle pigmentation, and antioxidant capacity in juvenile rainbow trout. Four experimental diets were formulated to contain 0, 50, 75, and 100 mg/kg astaxanthin (designed as AX0, AX50, AX75, and AX100). Each diet was fed to triplicate groups of fish (18.5 g/fish) for 10 weeks. Growth performance and muscle composition of fish were not affected by dietary astaxanthin levels. Total carotenoid concentration in the muscle of fish fed the AX50 diet was higher than that of fish fed the AX0 diet, but no significant differences were observed between these fish and those fed the AX75 and AX100 diets...

Toll-like receptor 21 (TLR21) is a non-mammalian TLR that functions similar to mammalian TLR9 in recognizing CpG DNA. In the present study, we identified a TLR21 homologue, LycTLR21, from large yellow croaker (Larimichthys crocea). The complete coding sequence of LycTLR21 is 2946 nucleotides long, encoding a protein of 981 amino acids. The deduced LycTLR21 protein has typical TLR domain architecture, including a signal peptide, 13 leucine-rich repeats (LRRs) in the extracellular region, a transmembrane region, and a cytoplasmic Toll-Interleukin-1 receptor (TIR) domain...

Long non-coding RNAs (lncRNAs), which are >200nt longer transcripts, potentially play important roles in almost all biological processes in plants and mammals. However, the functions and profiles of lncRNAs in fruit is less understood. Therefore, it is urgent and necessary to identify and analyze the functions of lncRNAs in sea buckthorns. Using RNA-sequencing, we synthetically identified lncRNAs in mature fruit from the red and yellow sea buckthorn. We obtained 567,778,938 clean reads from six samples and identified 3428 lncRNAs in mature fruit, including 2498 intergenic lncRNAs, 593 anti-sense lncRNAs, and 337 intronic lncRNAs...

From the 1940s through 1977, at least 590,000kg of polychlorinated biphenyls (PCBs) were released into the Hudson River from General Electric manufacturing plants located in Hudson Falls and Fort Edward, New York. In 1984, the U.S. Environmental Protection Agency designated a nearly 322km reach as the Hudson River PCBs Superfund Site. Here we describe a Fish Health Assessment study, part of a Natural Resource Damage Assessment, that evaluated the prevalence of toxicopathic lesions in adult brown bullhead (Ameiurus nebulosus), smallmouth bass (Micropterus dolomieu), and yellow perch (Perca flavescens)...

Effects of the developmental stage (e.g. young, mature or senescent) of leaves on their chemical composition have been described in literature. This study focuses on the variation in chemical composition and quantity and quality of proteins extracted from leaves due to variation in plant age (i.e. harvesting time), using leaves from sugar beets grown in field (Rhino, Arrival) and in greenhouse (Isabella). Within the same variety (Rhino-field, Arrival-field, Isabella-greenhouse) the protein content was similar for leaves from young and old plants (22±1, 16±1, and 10±3% w/w db, respectively)...

We explored the photoisomerization mechanisms in novel homologs of Photoactive Yellow Protein (PYP) from Leptospira biflexa to identify conserved features and functional diversity in the primary photochemistry of this family of photoreceptors. In close agreement with the prototypical PYP from Halorhodospira halophila, we observe excited state absorbance near 375 nm and stimulated emission near 500 nm, with triphasic excited state decay. While the excited state decay for Lbif PYP is the slowest among known PYPs due to the redistribution of the amplitudes of the three decay components, the quantum yield for productive photocycle entry is very similar to that of Hhal PYP...

Carbon storage is affected by photosynthesis (Pn) and soil respiration (Rs), which have been studied extensively in natural and agricultural systems. However, the effects of Pn and Rs on carbon storages in the presence of arbuscular mycorrhizal fungi (AMF) in coalfields remain unclear. A field experiment was established in 2014 in Shendong coal mining subsidence area. The treatments comprised two inoculation levels (inoculated with or without 100 g AMF inoculums per seedlings) and four plant species [wild cherry (Prunus discadenia Koebne L...

Connective tissues such as tendon, ligament and cartilage are mostly composed of extracellular matrix (ECM). These tissues are insoluble, mainly due to the highly cross-linked ECM proteins such as collagens. Difficulties obtaining suitable samples for mass spectrometric analysis render the application of modern proteomic technologies difficult. Complete solubilization of them would not only elucidate protein composition of normal tissues but also reveal pathophysiology of pathological tissues. Here we report complete solubilization of human Achilles tendon and yellow ligament, which is achieved by chemical digestion combined with successive protease treatment including elastase...

The early stages of speciation are often characterized by the formation of partially reproductively isolated ecotypes, which evolve as a byproduct of divergent selective forces that are endemic to different habitats. Identifying the genomic regions, genes, and ultimately functional polymorphisms that are involved in the processes of ecotype formation is inherently challenging, as there are likely to be many different loci involved in the process. To localize candidate regions of the genome contributing to ecotype formation, we conducted whole genome pooled-sequencing (pool-seq) with 47 coastal perennial and 50 inland annual populations of the yellow monkeyflower, Mimulus guttatus...

Ten strains were isolated from a spoiled large yellow croaker (Pseudosciaena crocea). All of them were able to grow aerobically from 4 °C to 30 °C, and reduce trimethylamine N-oxide (TMAO) to trimethylamine (TMA) and produce H2 S except the SB01, PF05 and PF07. Biochemical characterization and phylogenetic analysis of 16S rRNA gene showed that eight H2 S producing isolates were closely related to Shewanella baltica, and two isolates PF05 and PF07 were identified as P. fluorescens and P. fragi, respectively...

Yellow discoloration of the skin may be caused by several etiologies, including jaundice, hypervitaminosis, drug reaction or chemical exposure. Herein we describe a 68-year-old woman with a history of breast and thyroid carcinoma, presenting with a yellow discoloration of her soles, after ingestion of one capsule a day of turmeric root extract (Bluebonnet Turmeric Root, 500 mg, Vcap), taken for its anti-cancer properties, for 4 months. After drug cessation, the yellow hue disappeared completely. A Naranjo assessment score of 5 was obtained, indicating a probable relationship between the patient's symptom and her use of the drug...

The Zika virus (ZIKV) is a flavivirus of the family Flaviviridae, which is similar to dengue virus, yellow fever and West Nile virus. Recent outbreaks in South America, Latin America, the Caribbean and in particular Brazil have led to concern for the spread of the disease and potential to cause Guillain-Barré syndrome and microcephaly. Although ZIKV has been known of for over 60 years there is very little in the way of knowledge of the virus with few publications and no crystal structures. No antivirals have been tested against it either in vitro or in vivo...

In this study, we investigated the barley yellow mosaic virus (BaYMV, genus Bymovirus) factor(s) responsible for breaking eIF4E-mediated recessive resistance genes (rym4/5/6) in barley. Genome mapping analysis using chimeric infectious cDNA clones between rym5-breaking (JT10) and rym5-non-breaking (JK05) isolates indicated that genome-linked viral protein (VPg) is the determinant protein for breaking the rym5 resistance. Likewise, VPg is also responsible for overcoming the resistances of rym4 and rym6 alleles...

Two radiated tortoises (Astrochelys radiata) exhibited anorexia and hypokinesia. In both cases, hematological and serum biochemical examinations revealed high alkaline phosphatase levels, moderately high aspartate aminotransferase levels and white blood cell counts approximately within the normal range. Despite being treated, the tortoises died 9 and 43 days after the first clinical examination. Gross pathological examinations revealed that the livers of both animals were extremely swollen and contained pale yellow necrotic tissue...
