Simultaneous anammox-denitrification is effectively operated in two types, i.e., the anammox-denitritation (SAD pattern) and the anammox-denitratation (PDA pattern).

Here, the distribution patterns and assembly mechanisms of bacterioplankton communities in the estuary areas of the Taihu Lake were investigated using high-throughput sequencing and multivariate statistical analyses. Our results showed obvious seasonal variations in bacterioplankton diversity and community composition, which had significant correlations with water temperature.

For comprehensive insights into the effects of water supply suspension-restoration, this study characterized the variations of the pathogen community composition of the tap water and their infection risk under different water supply scenarios. Metagenomic sequencing revealed a significant change of the human pathogen profiles, among which the most dominant pathogen changed from Pseudomonas aeruginosa (4.

Para-chloronitrobenzene (p-CNB), a hazardous and toxic substance, is widely used as an intermediary in chemical industries. p-CNB can cause methaemoglobinaemia due to electron-withdrawing properties of the nitro and chlorine groups. We present a case of a 23-year-old man suffering from thermal burns and p-CNB poisoning.

HF enters the human body via where it contacts, such as skin and mucosa, alimentary and respiratory tracts, and ocular surfaces. In the recent years, the incidence of HF burn has tended to increase over time.

Objective: This study was designed to evaluate the efficiency and safety of arterial infusions of calcium gluconate to treat hydrofluoric (HF) acid burns of the distal human limbs.
Materials And Methods: Eligible patients with HF burn limbs, collected from January 2008 to October 2011, were given the arterial infusion of calcium gluconate into the injured limbs. The measures of pain were conducted before the infusion, immediately after the infusion, 4 h after the infusion, and 2 days after the infusion by the visual analogy score (VAS).

Objective: To compare the effects of different kind of methods in the management of hydrofluoric acid burn in early postburn stage in rabbits.
Methods: Thirty-three rabbits were inflicted with burn by 55% of hydrofluoric acid covering 5% TBSA, and were randomly divided into 3 groups, i.e.
