Research advance in the distribution and ecotoxicological effects of microcystins in aquatic ecosystem.

Cyanotoxins produced by the toxic cyanobacteria is a great threat to global freshwater ecosystems, with hepatotoxic microcystins (MCs) as the most widely distributed and harmful ones. MCs have negative impacts on the structure, function and stability of aquatic ecosystems, posing threats to human health. In this study, we reviewed the distribution of MCs in waterbody, sediments, and different groups of aquatic animals.

Modified fixation for periprosthetic supracondylar femur fractures: Two case reports and review of the literature.

Background: Periprosthetic supracondylar femoral fractures (PSFs) present a challenge in terms of optimizing fixation in patients with poor bone quality. Surgical treatment and peri-operative management of PSFs in the elderly remain a burden for orthopedic surgeons. Among different treatment options, locking plate (LP) and retrograde intramedullary nail (RIMN) have shown favorable results.

[Seasonal variation of phytoplankton community structure in the Tianhe Reservoir of the Daluoshan Mountain in southern Zhejiang Province, China and its indication to water quality].

To explore the association between phytoplankton community structure and water quality of the Tianhe Reservoir in Wenzhou, Zhejiang, we examined the phytoplankton and physico-chemical factors in the Tianhe Reservoir from February 2019 to January 2020. A total of 89 phytoplankton species belonging to 60 genera and 7 phyla were identified. The annual average abundance and biomass of phytoplankton were 2.

Fabrication and electromagnetic performance of talc/NiTiO composite.

In this study, the electromagnetic (EM) performance of talc/NiTiO composite was evaluated. The morphology of talc displayed a lamella structure; there were many nanoparticles of NiTiO coated on the talc lamella Thermal destruction occurred, which increased the surface area from 2.51 m g to 79.

Relationship Between the Serum Total Bilirubin and Inflammation in Patients With Psoriasis Vulgaris.

Background: Psoriasis is a chronic and recurrent inflammatory skin disease. Previous studies have shown that bilirubin has anti-inflammation and antioxidant effects. However, the various roles of bilirubin in psoriasis patients are still unclear.

De novo assembly and characterization of the global transcriptome for Rhyacionia leptotubula using Illumina paired-end sequencing.

Background: The pine tip moth, Rhyacionia leptotubula (Lepidoptera: Tortricidae) is one of the most destructive forestry pests in Yunnan Province, China. Despite its importance, less is known regarding all aspects of this pest. Understanding the genetic information of it is essential for exploring the specific traits at the molecular level.

[Chemical constituents of Pileostegia viburnoides var. glabrescens].

Objective: To study the chemical constituents of Pileostegia viburnoides var. glabrescens.

Methods: The compounds were isolated and purified by various techniques.

[Study on chemical constituents of volatile oil from rhizomes and leaves of Pileostegia viburnoides var. glabrescens by GC-MS].

Objective: To analyze the chemical constituents of volatile oil from the rhizomes and leaves of Pileostegia viburnoides var. glabrescens by GC-MS.

Methods: The volatile oil was extracted from the rhizomes and leaves of Pileostegia viburnoides var.

Mitochondrial genome of the pine tip moth Rhyacionia leptotubula (Lepidoptera: Tortricidae).

The complete nucleotide sequence of the mitochondrial genome of the pine tip moth Rhyacionia leptotubula (Lepidoptera, Tortricidae) was determined. The entire genome is 15,877 bp in length, encoding the standard set of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and an A+T-rich control region. The gene order is typical of Lepidoptera and differs from the insect ancestral type in the location of trnM.
