Allostatic Load and Oxidative Stress Markers in Women With Early- and Late-Onset Preeclampsia.
Cureus
December 2024
Coordination of Gynecological and Perinatal Endocrinology, National Institute of Perinatology Isidro Espinosa de los Reyes, Mexico City, MEX.
Background: Allostatic load and oxidative stress (OS) markers differ in women with and without preeclampsia. However, there is no difference in allostatic load and OS markers between late-onset preeclampsia (L-OP) and early-onset preeclampsia (E-OP). This study aimed to compare the concentrations of allostatic load and OS markers in pregnant women with L-OP and E-OP.

Background: Wilson's disease (WD) is a rare metabolic disorder of copper accumulation in organs such as liver, brain, and cornea. Diagnoses and treatments are challenging in settings, where advanced diagnostic tests are unavailable, copper chelating agents are frequently scarce, healthcare professionals lack disease awareness, and medical follow-ups are limited. Prompt diagnoses and treatments help prevent complications, improve patients' quality of life, and ensure a normal life expectancy.

Polymers (Basel)
January 2025
Unidad de Materiales, Centro de Investigación Científica de Yucatán, Calle 43 No. 130 Col. Chuburná de Hidalgo, Merida 97205, Mexico.
This research addresses the study of the combined effect of two abiotic treatments, a thermo-oxidative treatment followed by a photo-oxidative treatment with ultraviolet light, on the physicochemical properties of commercially available low-density polyethylene films with an oxo-degradant additive (OXOLDPE) and without (LDPE). The change in the oxidized film properties was characterized using FTIR, XRD, TGA, GPC, and SEM analytical techniques. The results indicated that the increment in carbonyl index (CI) and crystallinity percentage (X) was higher for those films that received the combined oxidative treatments compared with those that received only one of them, thermo- or photo-oxidative treatment.

Polymers (Basel)
January 2025
Instituto de Investigaciones en Físico-Química de Córdoba (INFIQC), Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Córdoba 5000, Argentina.
Lithium-sulfur (Li-S) batteries are promising candidates for next-generation energy storage due to their high energy density, cost-effectiveness, and environmental friendliness. However, their commercialization is hindered by challenges, such as the polysulfide shuttle effect, lithium dendrite growth, and low electrical conductivity of sulfur cathodes. Cellulose, a natural, renewable, and versatile biopolymer, has emerged as a multifunctional material to address these issues.

Link & Otto, an endemic plant of Mexico, is widely distributed in the central area of the country, mainly in the states of Tlaxcala, Puebla, and the State of Mexico. Ethnobotanical studies in different communities of these states have demonstrated that it is primarily used to treat diabetes and mental illnesses, such as "los nervios" (nerves) and "el ansia" (anxiety); these terms are used in traditional medicine, but it is accepted that they refer to anxiety disorders. This study aimed to validate the traditional use of aerial parts of Link & Otto in treating these illnesses.
