Abstract

Forty surface and twenty-two deeper sediment samples were collected from the Beijiang River and analyzed to acquire information about the levels, distribution, possible sources and influencing factors of polybrominated diphenyl ethers (PBDEs) in the Beijiang River. Our results showed that the most abundant BDE congeners in surface sediments were BDE47, 99 and 209, with a median value of 0.044, 0.03, and 5.22 ng g(-1), respectively. The levels of BDE209 in our samples were much higher relative to those of the other BDE congeners and made up more than 90% of the PBDEs levels in almost all samples. Disregarding BDE209, of the remaining 9 BDE congeners the most abundant ones were BDE47 and 99, which contributed 35.7% and 24.6%, respectively, to the median of the 9 congeners. The contribution of the Beijiang River to the PBDE pollution burden of the Pearl River Delta (PRD) was small in comparison to that of the Dongjiang River and the Guangzhou section of the Zhujiang River. PBDEs in the Beijiang River mainly came from use of deca-BDE and penta-BDE with a minor contribution of octa-BDE. The poor correlation between PBDE and TOC may indicate that PBDEs concentrations in the sediments of the Beijiang River were controlled not only by ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
