background: photodynamic therapy (pdt) is a promising therapeutic modality for the treatment of cancer and other diseases. in this study, the epidermoid carcinoma cell line a431 and the normal fibroblasts were used to investigate whether gold nanoparticles (gnps) can induce an increase in cell death during pdt using 5-aminolevulinic acid (5-ala) as a photosensitizer. methods: human fibroblast a...

During the last two decades, numerous observed data obtained by various physical techniques, also supported molecular modeling approaches, have highlighted structuring features of tripeptides, as well their aggregation properties. Herein, we focus on structural dynamics four trimers, i.e., Gly-Gly-Gly, Gly-Ala-Gly, Ala-Ala-Ala and Ala-Phe-Ala, in an aqueous environment. Density functional theor...

background: cryopreservation of pre-antral follicles is a hopeful technique to preserve female fertility. the aim of the present study was to evaluate reactive oxygen species (ros) and total antioxidant capacity (tac) levels of mouse vitrified pre-antral follicles in the presence of alpha lipoic acid (ala). methods: isolated pre-antral follicles (140–150 µm in diameter) were divided into vitrif...

As with traditional feed grains, the form in which flax seed is fed impacts egg production and hen performance (Choi et al. 1986, Vilarino et al. 1996). Flax seed form also affects the amount of omega-3 polyunsaturated fatty acid (PUFA) incorporated into the egg. Differences in the omega-3 content of eggs from laying hens fed whole versus milled flax seed have been reported, with many researche...

Introduction: This study evaluated the effects of pretreatments with melatonin (MT), and Alpha Lipoic acid (ALA) on lopinavir/ritonavir (LPV/r) -induced serum levels of creatinine (Cr), urea (U), uric acid (Ua) and kidney levels of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH) and catalase (CAT) in male albino rats. Effects of treatments with MT and ALA were also evaluate...

We present a class of decomposable inequality indices for ordinal data (e.g. self-reported health survey). It is characterized by well-known inequality axioms (e.g. scale invariance) and a decomposability axiom which states that an index can be represented as a function of inequality values in subgroups and subgroup sizes. The only decomposable indices are strictly monotonic transformations of ...
