Corrosion Induced on Aluminum by Biodiesel Components in Non-Oxygen Environments.

Biodiesel is a mixture of saturated and unsaturated Fatty Acid Methyl Esters (FAMEs) whose composition affects the corrosion behavior of metal containers during storage. This study examines the effect of the C=C bond present in selected FAMEs (Methyl Stearate, Methyl Oleate, and Methyl Linoleate) in aluminum corrosion in the absence of oxygen. First, mass loss assays were carried out at 100, 200, and 280 °C for 1000 h using pure Methyl Stearate (MS), 5% Methyl Oleate in Methyl Stearate (MS-5% MO), and 5% Methyl Linoleate in Methyl Stearate (MS-5% ML).

Phenolic Compounds of Therapeutic Interest in Neuroprotection.

The number of elderly people is projected to double in the next 50 years worldwide, resulting in an increased prevalence of neurodegenerative diseases. Aging causes changes in brain tissue homeostasis, thus contributing to the development of neurodegenerative disorders. Current treatments are not entirely effective, so alternative treatments or adjuvant agents are being actively sought.

leaf extracts decrease the proliferation and invasiveness of breast cancer cells.

Unlabelled: Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype due to its greater invasive capacity and non-response to hormone therapy. Several species of the genus have been used as an alternative to traditional medicine against malignant diseases. Previously, leaf extracts from showed antiproliferative activity in vitro against breast and cervical tumor cells without having a cytotoxic effect on non-tumor cell lines.

Cytotoxicity of Ficus Crocata Extract on Cervical Cancer Cells and Protective Effect against Hydrogen Peroxide-Induced Oxidative Stress in HaCaT Non-Tumor Cells.

Oxidative stress causes several chronic diseases including cancer. Some chemotherapeutic agents are not selective against tumor cells, causing oxidative stress in non-tumor cells. This study aimed to evaluate the cytotoxic effect of acetone extract of leaves (Ace-EFc) on cervical cancer cells, as well as its protective effect on hydrogen peroxide (HO)-induced lipoperoxidation and cytotoxicity in non-tumor HaCaT cells.

Phytochemical profile and antiproliferative effect of Ficus crocata extracts on triple-negative breast cancer cells.

Background: Some species of the Ficus genus show pharmacological activity, including antiproliferative activity, in cell lines of several cancer Types. ficus crocata is distributed in Mexico and used in traditional medicine, as it is believed to possess anti-inflammatory, analgesic, and antioxidant properties. However, as of yet, there are no scientific reports on its biological activity.

Biotransformation of benzo[a]pyrene by the thermophilic bacterium Bacillus licheniformis M2-7.

Benzo[a]pyrene (BaP) is recognized as a potentially carcinogenic and mutagenic hydrocarbon, and thus, its removal from the environment is a priority. The use of thermophilic bacteria capable of biodegrading or biotransforming this compound to less toxic forms has been explored in recent decades, since it provides advantages compared to mesophilic organisms. This study assessed the biotransformation of BaP by the thermophilic bacterium Bacillus licheniformis M2-7.

Chemical composition of Helietta parvifolia and its in vitro anticholinesterase activity.

The chemical composition of the essential oil and the n-hexane (Hex), Ethyl Acetate (EtOAc) and butanol (BuOH) extracts from the leaves of Helietta parvifolia were determined by detailed GC-MS analysis, spectroscopic and spectrometric data. Eighty-four compounds were identified, revealing a furoquinoline alkaloid-rich composition. The phytochemical analysis of the extracts allowed the isolation of eigth furoquinoline alkaloids.

Antinociceptive effect of natural and synthetic alkamides involves TRPV1 receptors.

Objective: To establish the role of TRPV1 receptor in the antinociceptive effect of natural alkamides (i.e. affinin, longipinamide A, longipenamide A and longipenamide B) isolated from Heliopsis longipes (A.

Anti-Helicobacter pylori, gastroprotective, anti-inflammatory, and cytotoxic activities of methanolic extracts of five different populations of Hippocratea celastroides collected in Mexico.

Ethnopharmacological Relevance: The root barks of Hippocratea celastroides have been used for decades in Mexican traditional medicine to treat gastritis and ulcers. To investigate the anti-Helicobacter pylori, gastroprotective, anti-inflammatory, and cytotoxic activities of methanolic extracts obtained from the leaves, stems, and root bark of Hippocratea celastroides collected in five different localities in Mexico, during the winter of 2009, in order to establish differences in biological activities in terms of plant organs, as well as places of collection.

Materials And Methods: Whole individuals were collected in five separate localities in Mexico: La Mancha, Veracruz (VL), Yautepec, Morelos (MY), Jojutla, Morelos (MJ), Temalac, Guerrero (GT), and Landa de Matamoros, Querétaro (QL).
