Antitumor effects and molecular mechanisms of natural product actions in ovarian cancer

Ovarian cancer is a general malignancy and the second causes of the second mortality among women with genital cancer. At present, postoperative platinum drugs and paclitaxel-based chemotherapy is the treatment of gold standard for ovarian cancer. However, patients who accept these chemotherapy often experience cumulative and susceptible toxic effects on chemotherapy resistance. Therefore, it is necessary to determine the more effective treatment options that will be tolerated by the patient.

Recent studies have reported the therapeutic effects of various natural products in patients with ovarian cancer. In particular, this natural ingredient does not induce bad effects on healthy cells and networks, indicating that natural products can function as a safe alternative treatment for ovarian cancer. The antitumor effect of natural products is associated with cell proliferation oppression and metastasis, autophagy stimulation, increased chemotherapy sensitivity, and apoptosis induction.

This review focuses on the effects of antitumor from several natural products, including curcumin, resveratrol, ginsenosides, (-) – epigallocatechin-3-gallate and quercetin, which is increasingly investigated as a therapeutic option in ovarian cancer, and discusses the molecular mechanism involved in cell proliferation, apoptosis, autophagy, metastasis and sensitization.

Diseasal disinfection disinfection of precursor products from UK lowland surface water: molecular weight and bromide

The study currently compares the impact of three different unit processes, coagulation, granular activated carbon (GAC), and novels suspended ion exchange technology (six), in disinfection with the potential formation of a by-product (DBPFP) of two British lowland water sources with medium For high bromide content. Special attention is given to the influence of organic molecular weight (MW) in DBPFP and the impact of bromide concentration. While some studies have investigated the impact of the MW fraction of liquid chromatography with an analysis of organic carbon detection (LC-OCD) in the elimination of dissolved organic carbon (DOC) with a different process, no one studies the effect of the MW doc fraction of this DBP analysis.

The impact of higher bromide concentrations is to reduce the total concentration of trihalomethane mass (THM) and haloacetic (HAA), in contrast to previous reported studies. The results showed that for the source of moderate bromide concentration (135 μg / L), the potential for THM formation was reduced by 22% or 64% after coagulation or six treatments. For high bromide content sources (210 μg / L), the elimination of the potential THM formation is 47% or 69% respectively after GAC or six treatments.

The trend was the same for Haas, although with a larger difference between two processes / feedwaters with reference to the overall removal. Statistical analysis shows that organic material MW> 350 g / mol has a significant impact on DBPFP. A multiple linear regression of the MW faction against DBPFP showed a strong correlation (R2 between 0.90 and 0.93), indicating that LC-OCD analysis could only be used to predict DBP formation with reasonable accuracy, and offering potential risk assessment fast source.

Putatatat SARS-COV-2 M Pro Inhibitors from the In-House Library of Natural Products and Nature-Inspired: Virtual Screening and Molecular Docking Studies

New Coronavirus (severe acute respiratory syndrome Coronavirus 2, SARS-COV-2) has been the cause of recent global pandemic. A very contagious nature of this life-threatening virus makes it very important to find therapy to ward off diffusion. The main protease (MPRO) SARS-COV-2 is a promising target of the drug because of its very necessary role in virus replication in the host. Using a combined two-step approach from virtual screening and molecular docking techniques, we have filtered small molecular in-house collections, especially consisting of natural compounds and nature inspired. Molecules are chosen with high structural diversity to close various chemical space into an enzyme bag. Virtual screening experiments are carried out using automodock vina software docking mode.

Virtual playback allows the selection of structural heterogeneous compounds that are able to interact effectively with the SARS-COV-2 MPRO enzymatic site. Compounds that show the best interaction with printed proteins by molecular docking as implemented in Autodock, while complex stability is tested by molecular dynamics. The most promising candidate reveals good ability to enter into a protein binding pocket and to reach two catalytic numbers. There is a high probability that at least one of the selected scaffes can promise for further research.

Evaluating platelet activation related to biomaterial degradation products using molecular markers

The increasing number of biodegradable medical devices can be used in the circulatory system. The effects of relegation products released from this medical device on blood may be gradual and cumulative. When they reach a critical level, they can cause thrombosis and other complications. For this reason, it is important to evaluate blood compatibility of relegation products for quality control and development of this device. In this study, we evaluated the relegation products of four biodegradable materials (collagen, polylactic acid, calcium phosphate ceramics, and magnesium) using molecular markers of thrombosis activation associated with thrombosis.

We find that relegation products activate platelets to a certain extent, and that degradation products generated during various periods of degradation time activate platelets to various degrees. These platelet activations occur through several mechanisms, most of which are associated with the physicochemical properties of degradation products, including ion concentration, pH, micro molecular, and molecular weight. Our findings not only provide a clearer understanding of the impact of the relegation product of the biodegradable device that contacts blood, but also provides material for filtering degradation behavior so that it can improve quality control for this device.
