Heavy metal(loid)s in the alluvium of Qiantang River, Jiaojiang River, and Yangtze River showed low to moderate pollution levels, with Cd posing the highest ecological risk, followed by Hg.

Differential effects of warming on the complexity and stability of the microbial network in and wetlands in Yancheng, Jiangsu Province, China.

The impact of climate warming on soil microbial communities can significantly influence the global carbon cycle. Coastal wetlands, in particular, are susceptible to changes in soil microbial community structure due to climate warming and the presence of invasive plant species. However, there is limited knowledge about how native and invasive plant wetland soil microbes differ in their response to warming.

Species delimitation of tea plants (Camellia sect. Thea) based on super-barcodes.

Background: The era of high throughput sequencing offers new paths to identifying species boundaries that are complementary to traditional morphology-based delimitations. De novo species delimitation using traditional or DNA super-barcodes serve as efficient approaches to recognizing putative species (molecular operational taxonomic units, MOTUs). Tea plants (Camellia sect.

To assess the cell lines on esophagogastroduod enoscopies of children with feeding difficulty, esophageal fistula and asthma with histologic abnormality.

The purpose of this study is to evaluate the cell lines seen on esophagogastoduodenoscopy (EGD) of children who have difficulties feeding, esophageal fistula, and asthma that has some histologic abnormalities.  This is a study that looked back at the medical records of 100 children whose cells had been surgically restored after being impacted by EA or TEF. A review of the instrumental tests that were carried out at our facility has been conducted in order to identify any lingering anatomic or functional abnormalities of the airways and gastrointestinal system that would explain the pulmonary clinical images.

Is biomagnetic leaf monitoring still an effective method for monitoring the heavy metal pollution of atmospheric particulate matter in clean cities?

The development of a reasonable method for predicting heavy metals (HMs) pollution in atmospheric particulate matter (PM) remains challenging. This paper presents an elution-filtration method to collect PM from the surface of Osmanthus fragrans in a very clean area (Guiyang, China). The aim is to evaluate the effectiveness of biomagnetic leaf monitoring as a simple and rapid method for assessing HMs pollution in clean cities.

Phylotranscriptomic analyses reveal deep gene tree discordance in Camellia (Theaceae).

Gene tree discordance is a significant legacy of biological evolution. Multiple factors can result in incongruence among genes, such as introgression, incomplete lineage sorting (ILS), gene duplication or loss. Resolving the background of gene tree discordance is a critical way to uncover the process of species diversification.

Distribution and sources of fluvial pollen in the middle reaches of the Yellow River in China and their relationship with vegetation and land use.

Understanding the processes determining the composition of alluvial pollen assemblages and its relationship with watershed vegetation is a prerequisite for alluvial palynological study. Palynological analysis of a total of 45 river water samples collected from the middle reaches of the Yellow River and its major tributaries, identifies the distribution patterns, possible sources of pollen and relationship with the catchment vegetation. The results reveal that the pollen assemblages in the middle reaches of the Yellow River is dominated by herbaceous taxa, and the pollen is mainly derived from fluvial sources.

Phylotranscriptomics of Theaceae: generic-level relationships, reticulation and whole-genome duplication.

Background And Aims: Theaceae, with three tribes, nine genera and more than 200 species, are of great economic and ecological importance. Recent phylogenetic analyses based on plastomic data resolved the relationships among the three tribes and the intergeneric relationships within two of those tribes. However, generic-level relationships within the largest tribe, Theeae, were not fully resolved.

Evaluation of serum zinc level and IL-18 mRNA expression in children with pneumonia.

Pneumonia is currently one of the leading causes of death in children. Increased susceptibility to pneumonia may be due to their decreased immunity. One of the reasons for the decrease in immunity is zinc deficiency.

Plasma gp96 is a Novel Predictive Biomarker for Severe COVID-19.

Early and effective identification of severe coronavirus disease 2019 (COVID-19) may allow us to improve the outcomes of associated severe acute respiratory illness with fever and respiratory symptoms. This study analyzed plasma concentrations of heat shock protein gp96 in nonsevere (including mild and typical) and severe (including severe and critical) patients with COVID-19 to evaluate its potential as a predictive and prognostic biomarker for disease severity. Plasma gp96 levels that were positively correlated with interleukin-6 (IL-6) levels were significantly elevated in COVID-19 patients admitted to the hospital but not in non-COVID-19 patients with less severe respiratory impairment.

Effect of nanoprocessing on the physicochemical properties of bovine, porcine, chicken, and rabbit bone powders.

The chemical composition and hardness of bovine bone, porcine bone, chicken bone, and rabbit bone were compared, as well as the influence of nanoprocessing on the physicochemical characteristics of these bone powders. A series of nanofabrication processes led to an increase in bone minerals and the loss of protein and fat. The hardness of softened bovine bone was still the largest, whereas chicken and rabbit bones were relatively soft.
