Anticancer mechanisms on pyroptosis induced by Oridonin: New potential targeted therapeutic strategies.

Pyroptosis is a type of inflammatory cell death that is triggered by the formation of pores on the cell membrane by gasdermin (GSDM) family proteins. This process activates inflammasomes and leads to the maturation and release of proinflammatory cytokines such as interleukin-1β (IL-1β) and interleukin-18 (IL-18). Pyroptosis, a form of programmed cell death, has been found to be associated with various biomolecules such as caspases, granzymes, non-coding RNA (lncRNA), reactive oxygen species (ROS), and NOD-like receptor protein 3 (NLRP3).

[Efficient Photolysis of Acid Orange 7 Using Low-frequency Electrodeless Lamp].

Using the low-frequency electrodeless lamp (LFEL) of 40 watts, the photodegradation of Acid orange 7 (A07) in water solution was studied. By applying a special reactor in which the light source was placed under the water, photodegradation efficiency of A07 using LFEL was compared with that using common UV mercury lamp. A few small degradation products were detected by GC-MS.

[Photodegradation of atenolol in aqueous nitrate solution].

The aqueous photolysis of beta-blocker atenolol (ATL) using Xe lamp as simulated solar irradiation source was investigated in the presence of nitrate ions. The effects of nitrate ion concentration, solution pH value, and concentration of bicarbonate and humic substance on the photodegradation of ATL were studied. The results showed that photodegradation of ATL in nitrate solution followed pseudo-first-order kinetics.

[Aerobic microbial degradation of polybrominated diphenyl ethers].

The biodegradation of 4, 4'-dibromodipheny ether (BDE15) and decabromodiphenyl ether (BDE209) by white rot fungi under aerobic conditions was studied. Effects of non-ionic surfactant Tween 80 and beta-cyclodextrin as solubilizers on the apparent solubilities and biodegradation rates of BDE15 and BDE209 were also evaluated. The results showed that both BDE15 and BDE209 were efficiently degraded by white rot fungi.

[Physiological effects of metsulfuron-methy on Elodea nuttallii].

Physiological effects of metsulfuron-methy on Elodea nuttallii was studied. The growth status, the photosynthetic pigments content and activities of anti-oxidation enzymes of Elodea nuttallii were examined with different contents of metsulfuron-methyl in cultural solution. The results showed that metsulfuron-methy could stimulate the sprout bourgeoning but restrained the growth of frond remarkably.

Beta-cyclodextrin and its derivatives-enhanced solubility and biodegradation of 2-nitrobiphenyl.

This paper investigated the effects of beta-cyclodextrins (beta-CD) and its two derivatives, hydroxypropyl-beta-cyclodextrin (HPCD) and carboxymethyl-beta-cyclodextrin (CMCD), on the solubility and biodegradation of 2-nitrophenyl by an Acinetbacter sp. Results showed that beta-CD, HPCD and CMCD could not be utilized by Acinetbacter sp. as sole carbon source and none of the CDs had toxic effects on the growth of the bacteria in the experiments; all the CDs could enhance the apparent solubility and accelerate the biodegradation of 2-nitrobipheny.

[Analysis on the removal efficiency of phosphorus in some substrates used in constructed wetland systems].

Constructed wetlands are widely used to purify wastewater in some developing countries. As filter substrates in such wetland, these substrates play important role on removal of pollutants from wastewater. Selecting suitable substrates is one of the effective ways to improve the performance of constructed wetland on treating wastewater.
