    Triazole and Pyridine Hybrid Molecules as Electron‐Transport Materials for Highly Efficient Green Phosphorescent Organic Light‐Emitting Diodes
    Wiley ; 2014
    In:  Israel Journal of Chemistry Vol. 54, No. 7 ( 2014-07), p. 971-978

    In: Israel Journal of Chemistry, Wiley, Vol. 54, No. 7 ( 2014-07), p. 971-978
    Abstract: A series of triazole and pyridine hybrid molecules, with a triazole core and pyridine periphery, were designed and synthesized as an electron‐transport layer (ETL) and a hole/exciton‐block layer for green phosphorescent organic light‐emitting diodes. Compared with the widely‐used electron‐transport material (ETM) of 3‐(biphenyl‐4‐yl)‐5‐(4‐ tert ‐butylphenyl)‐4‐phenyl‐4H‐1,2,4‐triazole (TAZ) with a triazole core, lower‐lying HOMO and LUMO energy levels were obtained with the introduction of pyridine rings onto the periphery of the molecules, giving improved electron injection and carrier confinement. Significantly reduced driving voltages were achieved in a device structure of ITO/HATCN (5 nm)/TAPC (40 nm)/CBP:8 wt % Ir(PPy) 3 (10 nm)/ETL (40 nm)/LiF (1 nm)/Al (90 nm), giving a maximum power efficiency of 72.2 lm W −1 and an external quantum efficiency of 21.8 %, due to the improved electron injection and transport and thus, more balanced carrier recombination, which are much higher than those of the device based on TAZ.

    Epigenetic Manipulation Induces the Production of Coumarin‐Type Secondary Metabolite from Arthrobotrys foliicola
    Wiley ; 2019

    In: Israel Journal of Chemistry, Wiley, Vol. 59, No. 5 ( 2019-05), p. 432-438
    Abstract: Pursuing epigenetic manipulation approach in fungi led to the isolation of an unusual coumarin metabolite from fungi. An addition of the histone deacetylase inhibitor, suberohydroxamic acid (SBHA), to the culture medium of Arthrobotrys foliicola induced production of the coumarin‐type secondary metabolite represented by a single intensive peak in the HPLC profile of the ethyl acetate extract. The compound which was identified as 4‐ethyl‐7‐hydroxy‐8‐methyl‐2 H ‐chromen‐2‐one ( 1 ) was isolated from nature for the first time. Moreover, the investigation on the remaining part of the HPLC profile led to the separation of 6‐ethyl‐2,4‐dihydroxy‐3‐methylbenzaldehyde ( 2 ) and ten 2,5‐diketopiperazine compounds ( 3 – 12 ). The structures of isolates were deduced by their mass and NMR spectroscopic data. The coumarin‐type secondary metabolite ( 1 ) with peculiar smell induced by epigenetic stimulation is found for the first time in the Arthrobotrys species and the family Orbiliaceae. We evaluated 1 for the cytotoxic, anti‐inflammatory, anti‐allergic and nematocidal activities, however, it was found inactive.

    Abstract: Abstract Golden pompano (Trachinotus ovatus) is a commercially important marine fish and is widely cultured in the coastal area of South China. We explored the distribution difference of intestinal microflora with the same growth condition and the difference of gut microflora with different growth rates fed with fermented soybean meal (FSM) and fish meal (FM) primary protein source. After 8 weeks of the breeding experiment, select significant growth fish (Zcd, 156.04 ± 1.04 g) average growth fish (Zc, 120.01 ± 1.05 g) stagnant growth fish (Zcx, 98.03 ± 1.08 g) in FSM and select average growth fish (Dc, 158.03 ± 1.02 g) in FM. Sequencing results show that a total of 86303 sequences had been obtained in the intestine of Trachinotus ovatus. The number of OTUs that can be annotated to the database was 2315 (98.97%). At the phylum level, Proteobacteria, Tenericutes, Spirochaetes and Firmicutes were the predominant phyla. Alpha diversity and beta diversity analyses show that gut microbes’ richness and diversity in the Dc group were the highest. The diversity of gut microbiota in the FSM: Zc 〉 Zcd 〉 Zcx. At the genus classification level, the differences between FM and FSM were mainly in Gueglia, Grimontia, Klebsiella, Alistipes, Staphylococcus, and Parasutterella (p 〈 0.05). Alistipes and Staphylococcus were the different genera between Dc and Zcd (p 〈 0.05). We found significant differences in the relative abundance of Ruegeria between the Zc and Zcd groups. Also, significant differences were found in the distribution of Brevinema, Ruegeria, Unidentified-Lachnospiraceae, Blautia, and Bacteroides between Zc and Zcx groups. The results showed that fermented soybean meal had an essential effect on gut microflora of T. ovatus with the unsynchronized growth.

    Abstract: The design of artificial systems that mimic highly evolved and finely tuned natural photosynthetic systems is a subject of intensive research. By incorporating electron‐deficient anthraquinone within the ligand backbone, a redox‐active Ni‐based tetrahedron was developed as a redox vehicle for the construction of an artificial photosynthesis system. The tetrahedron can encapsulate fluorescein within its cavity for light‐driven H 2 evolution, with the turnover number reaching 1200 moles H 2 per mole redox catalyst. This well‐designed supramolecular system displayed a significantly superior activities compared with the reference mononuclear compound or introducing an inactive inhibitor (ATP), which confirmed this enzymatic photocatalytic behaviour.

    Abstract: Pond water with algae blooms was collected, and maintained in the dark over a 2-day period without nutritional supplements. The physico-chemical parameters and the density of algae were measured. The concentration of NH 4+-N, DIN and PO4–P in water in darkness significantly increased, and the density of algae decreased significantly. Isolated water was exposed to three bio-remediation water treatments: addition of green algae, Bacillus subtilis and photosynthetic bacteria. After remediation, the concentrations of NH4+ -N, NO3- -N, DIN and PO4- -P in the three treatment groups were significantly lower than the control group. No difference was observed in the concentration of NO2–N between the control group and the photosynthetic bacteria group. Results from all treatments showed water quality deterioration along with increase in nitrogen and phosphorus concentrations. Bio-remediation methods can be effectively adapted in shrimp culture after algae decay, and one of the most promising biological remediation strategies is the use of green algae.

    Abstract: Six practical diets were formulated to contain 2.6 (the basal diet), 48.9, 95.5, 189.83, 382.4, 779.53 mg/kg vitamin C diet. After 8 weeks of feeding, growth performance, antioxidant status, and innate immunity of juvenile pufferfish were analyzed. Results showed that specific growth rate and protein efficiency ratio in fish fed diets supplemented with vitamin C were significantly higher than in fish fed the control diet. Dietary vitamin C significantly up-regulated the expression levels of growth hormone receptors and Insulin-like growth factor. Blood cell numbers and respiratory burst activity were enhanced in fish fed vitamin C diet. Serum alkaline phosphatase, glutamic-pyruvic transaminase, and glutamic-oxaloacetic transaminase activity were significantly influenced by the dietary vitamin C levels. Fish fed diets supplemented with vitamin C showed increased hepatic superoxide dismutase, glutathione peroxidase, and catalase activity, but decreased malondialdehyde activity. In addition, we found that dietary vitamin C can significantly up-regulate the expression levels of immune-related genes (HSP70, HSP90, BAFF, TNF-α and IL-6) in liver. These results indicate that dietary vitamin C can significantly influence growth performance, antioxidant status, and innate immunity of pufferfish.

    Abstract: There are a large number of pathogens in the water where fish live, and the mucosal-associated lymphoid tissues (MALTs), such as skin, gill and intestine, are the first contact parts when pathogens infect fish. The secreted mucus of these tissues constitutes the first barrier for fish against the invasion of external pathogens. Mucosal immunity can identify and neutralize pathogens and induces immunocytes to devour pathogens and the like. As a key factor in the mucosal immune system, the polymeric immunoglobulin receptor (pIgR) is capable of mediating the transport and secretion of polymeric immunoglobulins towards mucus. The effective secretion of the pIgR is necessary for polymeric immunoglobulins (pIg) to exert mucosal defence and plays a significant role in fish immunity. With the deepening of research into fish immunoglobulins, the pIgR has become a research hotspot. The molecular structure, genetic structure and expression pattern of the pIgR and the important role it plays in mucosal immunity were summarized in this study, which contributed to a deeper understanding of fish mucosal immunity and laid a foundation for further exploration of the action mechanism and functions of the pIgR in fish.

    Abstract: Ulcer disease has caused significant economic losses in the culture of snakehead fish Ophiocephalus argus (Cantor). Information available on Citrobacter freundii as a possible causal agent for this disease is scarce. In this study, a virulent strain, temporarily named GB1, was isolated from diseased snakehead fish suffering from ulcer disease and was identified as C. freundii through molecular and phenotypic methods. A phylogenetic tree was constructed to examine isolate GB1 and compare it to other known isolates. In addition, isolate GB1 has developed resistance to aminoglycosides, tetracyclines, and sulfonamides drugs for veterinary use in aquaculture as revealed when screened against a range of common antibiotics. To the best of our knowledge, this is the first report of ulcer disease caused by C. freundii in snakehead fish. Published

    Abstract: Aeromonas hydrophila is a Gram-negative opportunistic pathogen causing motile aeromonad septicemia, which results in great economic losses in freshwater fish farming. In this study, we investigated the effect of A. hydrophila on apoptosis of pufferfish blood cells. Total blood cell count, reactive oxygen species (ROS) production, cytoplasmic free-Ca2+ (cf-Ca2+) concentration, nitric oxide (NO) production, apoptotic cell ratio and the transcription levels of caspase-3 in the pufferfish blood cells were determined after A. hydrophila infection. Results showed that A. hydrophila infection significantly depressed the total blood cell count, and significantly increased ROS production, cf-Ca2+ concentration, NO production and apoptotic cell ratio. The transcription levels of caspase-3 increased significantly after A. hydrophila infection. Taken together, our results suggest that A. hydrophila infection alters ROS, cf-Ca2+, NO levels, and active caspase-3, which lead to cell apoptosis.

    Abstract: The ontogeny of the digestive tract in Platax teira was studied by means of optical microscopy from hatching to 30 days post-hatching. Collect fertilized eggs from P. teira broodstock, fertilize the eggs to hatch in hatching net bags, and rear the larvae in higher-place ponds. Observe the morphology and structure of the digestive tract of larvae 1-30 days post-hatching using tissue slicing technique. The results showed that the oral cavity of the larvae was closed and had not yet begun to differentiate at 1day post-hatching. Its digestive tract was close to the abdominal wall, and the yolk sac was completely dyed dark red. At 4 days post-hatching, the oropharyngeal cavity, esophagus, and stomach of the larvae had been communicated, and their oral cavity opened and food intake begins, entering the mixed period of endogenous nutrition and exogenous nutrition. Thereafter, the yolk sac gradually decreased to disappear, the esophagus, stomach, and intestines continued to differentiate, and their functions gradually improved. During 25-30 days post-hatching, the structure of the digestive tract of the larvae didn’t change much. Due to the increase in the size of the larvae, most changes in the digestive system are related to the complexity of the tissues and the size of the organs. Specifically, the number of mucosal folds and cells in the esophagus and intestine increases, and the gastric glands and pits in the stomach increase. The number of mucous membrane folds, mucosal epithelial cells and gastric glands in the digestive tract increase with the growth of the larvae, indicating that the development of the digestive system of P. teira is consistent with the growth of larvae, morphological development, feeding, metabolism and other functions consistently, its developmental stage is also adapted to the stages of the early development stage of P. teira.
