[Traditional Chinese medicine used as anti-aging agent by targeting nuclear factor erythroid 2-related factor 2 signaling pathway].

The imbalance of redox homeostasis is a major characteristic of aging and contributes to the pathogenesis of various aging-related diseases. As a regulatory hub of redox homeostasis, nuclear factor erythroid 2-related factor 2 (NRF2) can attenuate oxidative stress by activating the transcription of many antioxidant enzymes. China is the birthplace of traditional Chinese medicine (TCM) which has been wildly used as medicine for thousands of years.

Drug-coated balloons for treating lesions in large coronary vessels: A case report.

Background: Percutaneous transluminal coronary angioplasty, while an effective intervention, can frequently lead to acute occlusion with severe consequences. Although clinical trials have demonstrated the efficacy of drug-coated balloons (DCB) in treating acute coronary artery occlusion and in preventing restenosis, there has been limited exploration on the use of DCB in treating lesions in large vessels. Currently, DCB are only recommended for patients with small vessel lesions and in-stent restenosis lesions, those at high risk of bleeding, and other special groups of patients.

[Generation and release of Microcystin-lR by Microcystis aeruginosa under hydroquinone inhibition].

The generation and release of algal toxin Microcystin-LR (MCLR), as well as the intracellular organic chemicals were studied during the inhibition processes of Microcystis aeruginosa using hydroquinone as the inhibitor. According to the dose-effect relationship, the corresponding dosages of EC20, EC50, EC70, EC90, EC99 were added to the algae suspension. The TOC was determined by the total organic carbon analyzer, and the three-dimensional fluorescence spectrum was obtained by the fluorescence spectrophotometer.

[Preparation and characterization of zirconium hydroxide powder for fluoride adsorption].

The method co-precipitation was applied to preparation the zirconium hydroxide as a type drinking-water defluoridation adsorbent. The effect of the preparation conditions on the adsorptive capacity was studied. The optimization of preparation condition for zirconium hydroxide concludes that co-precipitation time is 10 h, pH value is 7.

[Study on the variation of algal activity during the electrochemical oxidation as inactivation method].

The paper studied the variation of algal activity during the electrochemical inactivation and the influence factors by the use of TTC-dehydrogenase activity and neutral red staining assays. The treatment reactor was consisted of Ti/RuO2 rod as anode and stainless steel pipe as cathode. The results showed that algal inactivation rate was 45% in cell density after 30 min treatment at 8 mA/cm2.

[Algal inactivation and removal by pulsed magnetic field with varying frequency].

The paper studied the algal inactivation and removal by pulsed magnetic field with varying frequency. The results indicated that algae could be inactivated and killed by the magnetic treatment for the circulating water sample. When the accumulated resident time reached 6 minutes, the algae became to die with the mortality of 94%.
