Application of earthworm can enhance biological power generation and accelerate sulfamethoxazole removal in agricultural soils.

Microbial degradation plays a crucial role in removing sulfonamides from soil, enhancing sulfamethoxazole (SMX) remediation. To further augment SMX removal efficiency and mitigate the transmission risk associated with antibiotic resistance genes (ARGs), this study proposes a novel approach that integrates micro-animals, microorganisms, and microbial fuel cell (MFC) technology. The results showed that earthworm-MFC synergy substantially reduces SMX content and ARGs abundance in soil.

Electrochemically Mediated S-Glycosylation of 1-Thiosugars with Xanthene Derivatives.

An efficient electrochemical dehydrogenative cross-coupling of benzylic C-H bonds with 1-thiosugars at room temperature is described. The direct S-glycosylation protocol avoids using any oxidant, which provides facile access to various glycosylated xanthene derivatives with up to 91% yield. This current electrooxidative reaction is characterized by high atom economy, high efficiency, mild reaction conditions, being environmentally benign, and excellent functional group tolerance.

Management of Dislocation of the Shoulder Joint with Ipsilateral Humeral Shaft Fracture: Initial Experience.

Objective: To gain a better understanding of the traumatic mechanism and to develop appropriate treatment for dislocation of the shoulder joint with an ipsilateral humeral shaft fracture.

Methods: This was an observational and descriptive study. Nine patients with traumatic shoulder dislocations associated with ipsilateral humeral shaft fractures who visited the emergency room and received treatment from January 2012 to June 2018 were retrospectively analyzed.

[Study on contribution factor to atmospheric .OH by O3, HONO, HCHO and H2O2 in spring at Mangdang Mountain, Fujian Province].

The observation was conducted in Mangdang Mountain, Nanping, Fujian Province in the spring of 2009. Ozone, HONO, HCHO and H2O2 which are regarded as the sources of .OH and other atmospheric components were measured.

[Observational study of formaldehyde in air, rain and fog water at a site on the Mangdang Mountain of Fujian, China].

Through 2,4-dinitrophenylhydrazine (DNPH) high-performance liquid chromatography (HPLC) method, the levels of formaldehyde in ambient air, rain and fog samples were measured in Mangdang Mountain, Fujian Province, from March to April 2009. The average concentrations of formaldehyde in ambient air, rain and fog are 4.0 x 10(-10), 2.

[Expression of nuclear autoantigenic sperm protein in platinum resistance ovarian cancer cell clones].

Objective: To study the expression of NASP in platinum resistance ovarian cancer cell clones (C0C1/DDP).

Methods: The proteins of C0C1 and C0C1/DDP were separated by highly sensitive two-dimensional differential gel electrophoresis (2-D DIGE) coupled with matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF-MS) to identify the proteins differentially expressed in cisplatin sensitive and cisplatin resistance cell lines.

Results: The investigators found a group of the distinct expressed proteins between C0C1 and C0C1/DDP.

[Stature estimation from length of tibias and fibulas measured in computed radiography of living body].

Objective: By measuring lengths of tibias and fibulas in computed radiography (CR) of living body, regression formulae for stature estimation were obtained from these measurements that were adapted to the population of northern adults of Han.

Methods: The length of tibias and fibulas were measured in radiography, including 422 subjects (207 men and 215 women). The body height of each subject was also recorded.

Determination of atmospheric hydroxyl radical by HPLC coupled with electrochemical detection.

The hydroxyl radical (*OH) plays a central role in the oxidation and removal of many atmospheric compounds. Measurement of atmospheric *OH is very difficult because of its high reactivity and low atmospheric abundance. In this article, a simple and highly sensitive method, high performance liquid chromatography coupled with coulometric detection (HPLC-CD), was developed to determine *OH indirectly by determining its reaction products with salicylic acid (SAL), 2,3-dihydroxybenzoic acid (2,3-DHBA), and 2,5-dihydroxybenzoic acid (2,5-DHBA).

[Preliminary study on HOx photochemical processes in urban atmosphere of Guangzhou City].

Simultaneous measurements of atmospheric hydroxyl radicals (OH) and other pollutants in Guangzhou city were carried out in July, 2000. The quantitative analysis of HOx reaction cycle during daytime in summer was made. The calculation results indicated that the total production rates of OH and HO2 were about 4.
