Poly(N-isopropylacrylamide)-Based Semi-interpenetrating Polymer Networks for Tissue Engineering Applications. 1. Effects of Linear Poly(acrylic acid) Chains on Phase Behavior

Fast microwave-assisted green synthesis of xanthan gum grafted acrylic acid for enhanced methylene blue dye removal from aqueous solution.

This review summarizes the main advances published over the last 15 years outlining the different methods of grafting, including reactive extruder systems, surface modification, grafting and graft copolymerization of synthetic and natural polymers with maleic anhydride and its isostructural analogues such as maleimides and maleates, and anhydrides, esters and imides of citraconic and itaconic acids, derivatives of fumaric acid, etc. Special attention is spared to the grafting of conventional and non&conventional synth etic and natural polymers, including biodegradable polymers, mechanism of grafting and graft copolymerization, in situ grafting reactions in melt by reactive extrusion systems, in solutions and solid state (photo& and plasma& induced graftings), and H&bonding effect in the rea ctive blend processing. The structural phenomena, unique properties and application areas of these copolymers and their various modifications and composites as high performance engineering materials have been also described.

Study of polymer-polymer complexes and blends of poly(N-isopropylacrylamide) with poly(carboxylic acid): 1. Poly(acrylic acid) and poly(methacrylic acid)

Polycystic ovary syndrome (PCOS) is a disease that currently affects many women of reproductive age. In recent years, the incidence of PCOS has increased, affecting 4% of all women worldwide, with a prevalence of 6% in Mexico. PCOS is a condition characterized by different metabolic, reproductive and hormonal disorders such as hyperandrogenism, chronic anovulation, menorrhagia or infertility. Patients commonly develop clinical alterations such as hirsutism, acne and in some cases, they become overweight or obese. Different medications and therapeutic methods from different literatures were evaluated, both pharmacological such as inositol, metformin, resveratrol, simvastatin, dapagliflozin, which showed great improvement, decreasing the levels of hyperandrogenism in patients, as well as non-pharmacological, of which significant improvements were found with a change in lifestyle, such as exercise, ketogenic diet and herbal medications such as chamomile and cinnamon, which showed a positive change in patients. It is important to make a diffusion and early diagnosis of PCOS, since in this way it will be possible to have a timely treatment, which can be individualized according to the characteristics and needs of each patient.
