TiO₂-ZnO-MgO mixed oxide nanomaterials (MONs) were synthetized via the sol-gel method and characterized by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS), transmission (TEM), nitrogen physisorption analysis, X-ray diffraction (XRD), UV-Vis diffuse reflectance (UV-Vis DRS), Fourier transform infrared (FTIR), color (Luminosity (L), a, b, Chrome, hue) parameters. Furthermore, antimicrobial activity of MONs was tested against Escherichia coli (EC),...
In this study, conditions for the ultrasound-assisted extraction (UAE) of soluble polyphenols from Psidium cattleianum (PC) leaves were optimized using response surface methodology (RSM) by assessing effect time (XET = 2, 4, and 6 min), sonication amplitude (XSA 60, 80, 100%), pulse cycle (XPC 0.4, 0.7, 1 s). Furthermore, UAE compared with a conventional aqueous-organic (AOE) method extracting total phenolics; moreover, phenolic profile HPLC antioxidant activity (DPPH, ABTS, FRAP) also...
Ornithine lipids (OLs) are widespread among Gram-negative bacteria. Their basic structure consists of a 3-hydroxy fatty acyl group attached in amide linkage to the α-amino ornithine and second ester-linked position first acid. OLs can be hydroxylated within secondary moiety this modification has been related increased stress tolerance. Rhizobium tropici, nodule-forming α-proteobacterium known for its tolerance, forms four different OLs. Studies function these have hampered due lack knowledge...
Mixed oxide nanoparticles (MONs, TiO2–ZnO–MgO) obtained by the sol-gel method were characterized transmission electron microscopy, (TEM, HRTEM, and SAED) thermogravimetric analysis (TGA/DTGA–DTA). Furthermore, effect of MONs on microbial growth (growth profiling curve, lethal sublethal effect) Escherichia coli, Salmonella paratyphi, Staphylococcus aureus Listeria monocytogenes, as well toxicity against Artemia salina concentration test (LC50) evaluated. exhibited a near-spherical in shape,...
Burkholderia cenocepacia is an important opportunistic pathogen, and one of the most striking features genus collection polar lipids present in its membrane, including phosphatidylethanolamine (PE) ornithine-containing (OLs), as well 2-hydroxylated derivatives PE OLs (2-OH-PE 2-OH-OLs, respectively), which differ from standard versions by virtue presence a hydroxyl group at C2 (2-OH) esterified fatty acyl residue. Similarly, lipid A-esterified myristoyl Salmonella typhimurium can have...
Mangiferin is an important xanthone compound presenting various biological activities. The objective of this study was to develop, characterize physicochemical properties, and evaluate the anti-topoisomerase activity poly(lactic-co-glycolic acid) (PLGA) nanoparticles containing mangiferin. were developed by emulsion solvent evaporation method optimal formulation obtained with a response surface methodology (RSM); showed mean size 176.7 ± 1.021 nm 0.153 polydispersibility index (PDI) value,...
The soursop fruit or Annona muricata (A. muricata) is recognized by its bioactive compounds and acetogenins (ACG) are among the most important. effect of ACGs, with greater importance in health, that they present anti-tumor activity; however, methods extraction ACGs very slow a high expenditure solvents. To our knowledge, there no report an optimal method for from Annonaceae family ultrasound-assisted (UAE); therefore, aim was to find best UEA conditions A. (peel, pulp, seed, columella)...
The synthesis and characterisation of Ti–Zr mixed oxides containing 1 to 10 wt.% Zr is herein reported. In addition, the samples were tested as photocatalysts in generation hydrogen from aqueous methanol solutions. solids prepared by sol-gel then characterised X-ray diffraction, high resolution electron microscopy, photoelectron spectroscopy, physisorption nitrogen, scanning UV-vis Raman spectroscopies. results show presence anatase a predominant structure present larger specific surface...
Obesity is the result of a complex combination psychological, biological, and environmental factors. In this work, we evaluate whether obesity related to eating habits, depressive symptomatology, as well interleukin-8 cortisol. A descriptive cross-sectional study was carried out in 232 university students. All youths were surveyed determine their habits symptomatology. Anthropometric measures blood sample taken its biochemical profile concentration The results show that increase overfat...
The purpose of this study was to analyze the association between components diet, metabolic risks, and serum concentrations adiponectin interleukin-6 (IL-6). With prior informed consent, an analytical cross-sectional carried out with 72 students in their first year university. subjects had a mean age 19.2 ± 1.0 years body mass index 23.38 4.2, they were mainly women (80.6%). Sociodemographic, anthropometric, dietary data risk factors evaluated, biochemical parameters adipocytokines also...
Abstract Background Adiponectin is a biomarker useful for the early diagnosis of obesity-related comorbidities. The Mexican population has one highest obesity rates worldwide. purpose this study was to determine whether an association exists between adiponectin and certain sociodemographic nutrition-related factors in young adults. This perhaps only few studies focused Los Altos, Jalisco area, center religious cultural traditions Mexico. Methods A cross-sectional analysis conducted from...
ABSTRACT Sulfoquinovosyl diacylglycerol (SQDG) is a membrane-forming lipid present in photosynthetic organisms as well distinct bacteria growing phosphate-limited environments. Four genes for SQDG biosynthesis were previously identified Rhodobacter sphaeroides , the operon sqdBDC and sqdA . In this work, we found that SMc02490 of Sinorhizobium meliloti an SqdA orthologue. Expression S. Escherichia coli results formation sulfoquinovosyl glycerol (SQGro), while co-expression together with...
