AIM To evaluate the relation between 12 polymorphisms and the development of gastric cancer(GC) and colorectal cancer(CRC).METHODS In this study,we included 125 individuals with GC diagnosis,66 individuals with CRC diagnosis and 475 cancer-free individuals. All participants resided in the North region of brazil and authorized the use of their samples. The 12 polymorphisms(in CASP8,CYP2 E1,CYP19 A1,IL1 A,IL4,MDM2,NFKb1,PAR1,TP53,TYMS,UGT1 A1 and XRCC1 genes) were genotyped in a single PCR for each individual,followed by fragment analysis. To avoid misinterpretation due to population substructure,we applied a previously developed set of 61 ancestryinformative markers that can also be genotyped by multiplex PCR. The statistical analyses were performed in Structure v.2.3.4,R environment and SPSS *** After statistical analyses with the control of confounding factors,such as genetic ancestry,three markers(rs79071878 in IL4,rs3730485 in MDM2 and rs28362491 in NFKb1) were positively associated with the development of GC. One of these markers(rs28362491) and the marker in the UGT1 A1 gene(rs8175347) were positively associated with the development of CRC. Therefore,we investigated whether the joint presence of the deleterious alleles of each marker could affect the development of cancer and we obtained positive results in all analyses. Carriers of the combination of alleles RP1 + DEL(rs79071878 and rs28361491,respectively) are at 10-times greater risk of developing GC than carriers of other combinations. Similarly,carriers of the combination of DEL + RARE(rs283628 and rs8175347) are at about 12-times greater risk of developing CRC than carriers of other *** These findings are important for the comprehension of gastric and CRC development,particularly in highly admixed populations,such as the brazilian population.

N-11-azaartemisinins potentially active against Plasmodium falciparum are designed by combining molecular electrostatic potential (MEP), ligand-receptor interaction, and models built with supervised machine learning methods (PCA, HCA, KNN, SIMCA, and SDA). The optimization of molecular structures was performed using the b3LYP/6-31G* approach. MEP maps and ligand-receptor interactions were used to investigate key structural features required for biological activities and likely interactions between N-11-azaartemisinins and heme, respectively. The supervised machine learning methods allowed the separation of the investigated compounds into two classes: cha and cla, with the properties εb>LUMO+1b> (one level above lowest unoccupied molecular orbital energy), d(Cb>6b>-Cb>5b>) (distance between Cb>6b> and Cb>5b> atoms in ligands), and TSA (total surface area) responsible for the classification. The insights extracted from the investigation developed and the chemical intuition enabled the design of sixteen new N-11-azaartemisinins (prediction set), moreover, models built with supervised machine learning methods were applied to this prediction set. The result of this application showed twelve new promising N-11-azaartemisinins for synthesis and biological evaluation.

The aim of this study was to characterize tinctures and microcapsules loaded with an ethanol extract of red propolis through chemical, physicochemical and microbiological assays in order to establish quality control tools for nutraceutical preparations of red propolis. The markers(isoflavonoids, chalcones, pterocarpans,flavones, phenolic acids, terpenes and guttiferones) present in the tinctures A and b were identified and confirmed using LC/ESI/FTMS/Orbitrap. Four compositions(A, b, C and D) were prepared to contain b tincture of the red propolis with some pharmaceutical excipients and submitted to two drying processes, i. ***-drying and freeze-drying to obtain microcapsules loaded with the red propolis extract. The tinctures and microcapsules of the red propolis were submitted to the total flavonoid content and antioxidant activity *** antibacterial activity and minimum inhibitory concentration(MIC) were tested using Staphylococcus aureus ATCC 25293 and Pseudomonas aeruginosa ATCC 27853 strains. The tinctures and microcapsules presented high flavonoid quantities from 20.50 to 40.79 mg/100 mg of the microcapsules. The antioxidant activity and IC50 were determined for the tinctures A and b(IC50: 6.95 μg/m L and 7.48 μg/m L), the spray-dried microcapsules(IC50: 8.89–15.63 μg/m L) and the freeze-dried microcapsules(IC50: 11.83–23.36 μg/m L). The tinctures and microcapsules were proved to be bioactive against gram-positive and gram-negative bacteria with inhibition halos superior to 10 mm at concentration of 200 μg/m L and MIC values of 135.87–271.74 μg/m L using gram-positive strain and 271.74–543.48 μg/m L using gram-negative strain. The tinctures and microcapsules of the red propolis have a potential application for nutraceutical products.
