Chemical peels have been time-tested and are here to stay. Alpha-hydroxy peels are highly popular in the dermatologist's arsenal of procedures. Glycolic acid peel is the most common alpha-hydroxy acid peel, also known as fruit peel. It is simple, inexpensive, and has no downtime. This review talks about various studies of glycolic acid peels for various indications, such as acne, acne scars, me...

Although microalgae produce value-added products, such as lipids, pigments, and polysaccharides using light carbon dioxide, these intracellular products require costly downstream processes extraction purification. Thus, extracellular are desirable for economic production. While reported before, the secretion of glycolic acid by microalgal photorespiration has not received attention industrial a...

Abstract Catalytic valorization of raw glycerol derived from biodiesel into high-value chemicals has attracted great attention. Here, we report chemoenzymatic cascade reactions that convert to lactic acid and glycolic acid. In the enzymatic step, a coenzyme recycling system was developed 1,3-dihydroxyacetone (DHA) with yield 92.3% in potassium phosphate buffer (300 mM, pH 7.1) containing 100 mM...

attempts have been made to prepare nanoparticles based on poly(lactic-co-glycolic acid) (plga) and doxorubicin. biological evaluation and physio-chemical characterizations were performed to elucidate the effects of initial drug loading and polymer composition on nanoparticle properties and its antitumor activity. plga nanoparticles were formulated by sonication method. lactide/glycolide ratio a...

Ascorbic acid overload and vitamin B6 deficiency have been implicated in the development of hyperoxalemia in dialysis patients, but there is still disagreement about this. Hemodialysis patients who are exposed long-term hyperoxalemia may develop secondary oxalosis with an increased risk of cardiac, vascular, and bone disease, and thus may benefit from maintaining a low serum oxalic acid level. ...

Rosacea is a common skin condition that affects an estimated 13 million Americans, with almost half of these patients between the ages of 30 and 50 years old [1]. It is a relapsing, chronic dermatosis that develops in stages and is characterized by a defect in vascular responsiveness [2,3]. Most often, fair-skinned individuals are seen first with flushing and blushing episodes followed by persi...

The glycolate-oxidizing, sulfate-reducing bacterium strain PerGlyS and the syntrophically glycolate-oxidizing bacterium strain FlGlyR were studied with respect to their phylogenetic relationships on the basis of in vitro amplification and direct sequencing of 16s rRNA-encoding DNA. Strain PerGlyS clustered with representatives of the S subclass of the class Proteobacteria, close to “Desulforhop...

PURPOSE The purpose of this study was to investigate the feasibility of poly lactic/glycolic acid (PLGA) as a drug delivery carrier of Rho kinase (ROCK) inhibitor for the treatment of corneal endothelial disease. METHOD ROCK inhibitor Y-27632 and PLGA were dissolved in water with or without gelatin (W1), and a double emulsion [(W1/O)/W2] was formed with dichloromethane (O) and polyvinyl alcoh...

Structural characterization of poly-l-lactic acid (P(L)LA) and poly(glycolic acid) (PGA) oligomers containing three units was carried out with an atomistic approach. Oligomer structures were first optimized through quantum chemical calculations, using density functional theory (DFT); rotational barriers concerning dihedral angles along the chain were then investigated. Diffusion coefficients of...

The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from (14)CO(2) into glycolic acid, glycine, and serine, while...
