Monitoring and discussion on river carbon and nitrogen fluxes in the Pearl River Estuary region.

Rivers link land and sea, playing an important role in the global carbon and nitrogen cycles. By conducting surveys and research on river flow in a specific region, we can gain a better understanding of the nitrogen and carbon sinks in the area and their contributions to the environment. In this study, we conducted bi-annual sampling and monitoring of river flow in the Pearl River Delta downstream of Zhuhai, China, and collected hydrological information.

Chemical weathering rates and controlling mechanisms of glacial catchments within different climate regimes in the Tibetan Plateau.

Background: Continental weathering plays an important role in regulating atmospheric CO levels. Chemical weathering in glacial areas has become an intensely focused topic in the background of global change compared with other terrestrial weathering systems. However, research on the weathering of the glacial areas in the Yarlung Tsangpo River Basin (YTRB) is still limited.

Horizontal transmission and recombination of Wolbachia in the butterfly tribe Aeromachini Tutt, 1906 (Lepidoptera: Hesperiidae).

Wolbachia is arguably one of the most ubiquitous heritable symbionts among insects and understanding its transmission dynamics is crucial for understanding why it is so common. While previous research has studied the transmission pathways of Wolbachia in several insect lineages including Lepidoptera, this study takes advantage of data collected from the lepidopteran tribe Aeromachini in an effort to assess patterns of transmission. Twenty-one of the 46 species of Aeromachini species were infected with Wolbachia.

Association of Transforming Growth Factor β1 Gene Polymorphisms and Inflammatory Factor Levels with Susceptibility to Sepsis.

To study the association of transforming growth factor β1 (TGF-β1) gene single nucleotide polymorphisms (SNPs) and plasma TGF-β1 levels with susceptibility to sepsis. The genotypes of the gene rs1800469, rs1800468, rs1800470, and rs1800471 loci in 285 sepsis patients (119 patients with severe sepsis and 166 patients with mild sepsis) and 285 healthy individuals (control group) were analyzed through Sanger sequencing. Enzyme-linked immunosorbent assay was used to detect the levels of plasma inflammatory factors.

Diversity, Composition and Functional Inference of Gut Microbiota in Indian Cabbage white (Lepidoptera: Pieridae).

We characterized the gut microbial composition and relative abundance of gut bacteria in the larvae and adults of by 16S rRNA gene sequencing. The gut microbiota structure was similar across the life stages and sexes. The comparative functional analysis on bacterial communities with PICRUSt showed the enrichment of several pathways including those for energy metabolism, immune system, digestive system, xenobiotics biodegradation, transport, cell growth and death.

Phylogeny and Density Dynamics of Infection of the Health Pest Curtis (Coleoptera: Staphylinidae).

The maternally inherited obligate intracellular bacteria infects the reproductive tissues of a wide range of arthropods and affects host reproduction. is a credible biocontrol agent for reducing the impact of diseases associated with arthropod vectors. is a small staphylinid beetle that causes dermatitis linearis and conjunctivitis in humans when they come into contact with skin.

Early-life intestinal microbiome in analyzed using 16S rRNA sequencing.

During the early-life period, the hatchlings of red-eared slider turtles () rely on their own post-hatching internal yolk for several days before beginning to feed. The gut microbiome is critical for the adaptation of organisms to new environments, but, to date, how the microbiome taxa are assembled during early life of the turtle is unknown. In this study, the intestinal microbiome of red-eared slider hatchlings (fed on commercial particle food) was systematically analyzed at four different growth stages (0 d, 10 d, 20 d, 30 d) by a high-throughput sequencing approach.

[Value of early enteral nutrition in patients with severe heart failure undergoing mechanical ventilation].

Objective: To observe the effect of early enteral nutrition (EEN) on nutritional indicators and clinical outcomes in patients with severe heart failure undergoing mechanical ventilation.

Methods: Thirty-four patients with severe heart failure (grade III-IV of cardiac function) and pulmonary infections undergoing mechanical ventilation admitted to intensive care unit (ICU) of Second Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from May 2017 to April 2018 were enrolled. They were randomly divided into EEN group and delayed enteral nutrition (DEN) group.

Molecular Phylogeny and Historical Biogeography of the Butterfly Tribe Aeromachini Tutt (Lepidoptera: Hesperiidae) from China.

The butterfly tribe Aeromachini Tutt, 1906 is a large group of skippers. In this study, a total of 10 genera and 45 species of putative members of this tribe, which represent most of the generic diversity and nearly all the species diversity of the group in China, were sequenced for two mitochondrial genes and three nuclear genes (2093 bp). The combined dataset was analyzed with maximum likelihood inference using IQtree.
