[Effects of Different Colored Polycarbonate Plastics on Growth and Community Structure of Periphytic Algae].

Periphytic algae are important primary producers in water bodies, which play an important role in maintaining ecological function and water purification. Previous studies have shown that plastic is a good substrate for periphytic algae, and different plastic materials have different effects on the colonization of periphytic algae; however, there are few reports on the effects of plastic color on the growth of periphytic algae. In this study, polycarbonate plastic (PC) of various colors were used as the substrate to study the effects of different colors on the growth and community structure of periphytic algae by measuring the biomass, photosynthetic activity, and community composition.

[Role of Contrast-enhanced Ultrasound in Distinguishing between Benign and Malignant Thyroid Nodules with Calcification].

Objective To explore the roles of conventional ultrasound and contrast-enhanced ultrasound in distinguishing between benign and malignant thyroid nodules with calcification. Methods A total of 102 solid thyroid nodules with calcification in 76 patients were evaluated by conventional ultrasound alone and conventional ultrasound combined with contrast-enhanced ultrasound.The features obtained through conventional ultrasound alone and that combined with contrast-enhanced ultrasound were scored,and the diagnostic performance of the two methods was analyzed based on the final pathological results.

The novel MICB*004:02 allele differs from the closest allele MICB*004:01by a synonymous mutation in exon 2.

[Toxicological Effects of Enrofloxacin and Its Removal by Freshwater Micro-Green Algae sp].

Enrofloxacin (ENR), a fluoroquinolones antibiotic, is widely used in the medical and aquaculture fields. Its residues in surface waters in China are high. However, few studies have evaluated both its toxicity to phytoplankton and the degradation or removal by microalgae.

[Utilization and growth response of Chrysosporum ovalisporum to different phosphorus compounds].

To explore the ability of bloom-forming cyanobacterium Chrysosporum ovalisporum to utilize different kinds of phosphorus compounds in the water column, we examined the growth response of C. ovalisporum in the laboratory by taking dipotassium hydrogen phosphate as the control and set different treatments of phosphorus substrates. The results showed that C.

Identification of a novel allele, MICA*088N, in a Chinese Kazakh individual.

The novel MICA*088N allele has a single nucleotide mismatch in exon 4 compared to MICA*027.

[Characteristics of Phytoplankton Community and Its Relationship with Environmental Factors in Different Regions of Yilong Lake, Yunnan Province, China].

Yilong Lake, a shallow, plateau lake, is the ninth largest water body in the Yunnan Province, China. In order to figure out the characteristics of phytoplankton communities in different regions of this lake, the phytoplankton and environmental factors in the west region, east region, and in a submerged macrophytes restoration demonstration region were monthly investigated and analyzed from August 2013 to July 2014. The results showed that the habitats in different regions were spatially heterogeneous.

Characterization of a novel MICB variant in an individual from the Chinese Uyghur population, MICB*005:09, by cloning and sequencing.

A new allelic variant in MICB*005 lineage, MICB*005:09, has been identified in a male Uyghur individual recruited from Xinjiang Uyghur Autonomous Region, China by PCR-sequence-based typing (Sanger sequencing) and confirmed by cloning and sequencing. Aligned with MICB*005:03, this new allelic variant shows a synonymous T substitution at nucleotide position 8 in exon 2, corresponding to codon 3 (CAC→CAT) of the mature MICB mRNA transcript.

Furostanol and Spirostanol Saponins from Tribulus terrestris.

Twelve new steroidal saponins, including eleven furostanol saponins, terrestrinin J-T (1-11), and one spirostanol saponin, terrestrinin U (12), together with seven known steroidal saponins 13-19 were isolated from T. terrestris. The structures of the new compounds were established on the basis of spectroscopic data, including 1D and 2D NMR and HRESIMS, and comparisons with published data.

[Qualitative analysis of chemical constituents in Si-Wu Decoction based on TCM component database].

In order to clarify the chemical constituents of Si-Wu Decoction rapidly and holistically, we analyzed the ethanol extract of Si-Wu Decoction by UPLC/Q-TOF-MSE and UNIFI which based on traditional Chinese medicine database, the probable structures of 113 compounds were identified. The results show that this method can rapidly and effectively characterize the chemical compounds of Si-Wu Decoction and provide a new solution for identification of components from complex TCM extract.

[Analysis and identification of chemical constituents in Siwu decoction by UPLC-Q-TOF-MS(E)].

This research analyzed the chemical constituents of Siwu decoction by UPLC-Q-TOF-MS(E). Base on the data of mass and related-literatures, 43 peaks were profiled and 25 compounds, which contain 8 monoterpene glycosides from Paeonia lactiflora and 13 phthalides from Rhizoma chuanxiong and Radix angelica sinensis mainly, were identified in both positive and negative mode respectively. Meanwhile, chemical constituents of water extract and 60% ethanol extract of Siwu decoction were compared by the principal constituent analysis with MarkerLynx software, which provides the basis for the active ingredients of Siwu decoction.

New oleanane-type triterpenoid saponins isolated from the seeds of Celosia argentea.

Three new oleanane-type triterpenoid saponins named celosins H, I, and J were isolated from the seeds of Celosia argentea L. Their structures were characterized as 3-O-β-D-xylopyranosyl-(1 → 3)-β-D-glucuronopyranosyl-polygalagenin 28-O-β-D-glucopyranosyl ester, 3-O-β-D-glucuronopyranosyl-medicagenic acid 28-O-β-D-xylcopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-fucopyranosyl ester, and 3-O-β-D-glucuronopyranosyl-medicagenic acid 28-O-α-L-arabinopyranosyl-(1 → 3)-[β-D-xylcopyranosyl-(1 → 4)]-α-L-rhamnopyranosyl-(1 → 2)-β-D-fucopyranosyl ester by NMR, MS, and chemical evidences, respectively.

High-sensitivity detection of fruit tree viruses using bacterial magnetic particles.

Prunus necrotic ring spot virus (PNRSV) and grapevine fanleaf virus (GFLV) were detected by fluoroimmunoassay using bacterial magnetic particles (BMPs), and a double antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA). For the fluoroimmunoassay, fluorescein isothiocyanate labeled anti-PNRSV antibody or anti-GFLV antibody was conjugated onto BMPs of Magnetospirillum gryphiswaldense MSR-1. With this method, a very low minimum antigen concentration (1 x 10(6) dilution of the original sample concentration) could be detected.
