Mild hypothermia pretreatment improves hepatic ischemia-reperfusion injury: A systematic review and meta-analysis of animal experiments.

Background And Aim: Mild hypothermia in hepatic ischemia-reperfusion injury is increasingly being studied. This study aimed to conduct a systematic evaluation of the effectiveness of mild hypothermia in improving hepatic ischemia-reperfusion injury.

Methods: We systematically searched CNKI, WanFang Data, PubMed, Embase, and Web of Science for original studies that used animal experiments to determine how mild hypothermia(32-34°C) pretreatment improves hepatic ischemia-reperfusion injury(in situ 70% liver IR model).

Oral health self-management barriers among rural older adults in Guangxi, China: A qualitative study.

Background: Objective: To understand the barriers associated with self-management of oral health among rural older adults in Guangxi, and to explore the high incidence of oral problems. This information will assist in the formulation of relevant strategies to solve the oral health problems in this population.

Methods: Taking a phenomenological approach, the current status of, and barriers to, oral health self-management in rural older adults from different regions of Guangxi were explored.

[Health Effects of PM Based on Bacterial Toxicity Test and Transcriptional Analysis in Lungs of Mice].

Although epidemiology and toxicology studies have demonstrated that exposure to ambient air particles could result in a variety of lung diseases, but the pulmonary toxicological mechanism remains obscure. In this study, the toxicity of PM particles in different concentrations was investigated by toxicological methods, including the luminescent bacteria acute toxicity test and genotoxicity performed by SOS chromogenic reaction. The results indicated that, the acute toxicity and genotoxicity were low and negative, respectively.

Rapid dye degradation with reactive oxidants generated by chloride-induced peroxymonosulfate activation.

Transition-metal is known to catalyze peroxymonosulfate (PMS) decomposition to produce sulfate radicals. Here we report reactions between PMS and chloride, without a need of transition metals, also can be used to degrade organic dye pollutant (Rhodamine B, (RhB)). Some important operating parameters, such as dosages of PMS and Cl(-), pH of solution, temperature, ionic strength, and several common cations, were systematically investigated.

Sorption of BTEX mixtures to organobenonites.

Organobentonites synthesized by replacing the metal ions in bentonite with cetyltrimethylammonium (CTMA) or tetramethylammonium cation (TMA) were investigated for their behaviors to sorb benzene, toluene, p-xylene from water. The results served to distinguish the sorption mechanisms (adsorption or partition) of the two types of organobentonites. Bentonites modified with short-chain alkyl functional groups (e.
