The vitamin E analogue, α-tocopherol succinate (α-TOS), has a broad anti-tumor effect. α-TOS can induce cancer cells apoptosis and suppress tumor growth by targeting mitochondria. Low bioavailability of α-TOS is the major problem encountered with formulation development. In our study, α-TOS nanoemulsion (α-TOS-NE) was demonstrated as a new drug delivery system of α-TOS to increase the bioavailability. MTT-based cytotoxicity assay and mitochondrial membrane potential (ΔY) were performed on human breast cancer cell lines MCF-7 and human oral epithelial cancer cell lines KB to evaluate in vitro anticancer efficacy of α-TOS-NE...

Diabetes is a common metabolic disorder characterized by elevated blood glucose level. Trace element homeostasis causes disturbances in diabetes due to hyperglycemia. Superoxide dismutase (SOD), an antioxidant enzyme, contains zinc and copper ions as its cofactors. Defects in SOD level and activity have been observed in diabetes. Resveratrol (RSV) has displayed hypoglycemic effects and is proven to improve oxidative stress. The aim of the present study was to examine the possible effects of RSV on blood glucose level, serum copper and zinc levels, SOD, and a number of other oxidative markers in type 2 diabetic rats...

Neurogenic thoracic outlet syndrome (TOS) is one of the most controversial pain syndromes of the upper limbs. The controversies revolve around both the diagnosis and treatment of the non-specific or subjective subtypes. Their diagnosis rests on a combination of history, suggestive symptoms and clinical examination. Proximal pain is primarily muscular in origin, while distal symptoms may be the result of intermittent nerve compression and/or myofascial pain syndrome. Stringent clinical criteria are required to confirm the diagnosis of subjective TOS...

Well-structured amphiphilic copolymers are necessary to obtain self-assembled nanoparticles (NPs) based on synthetic polymers. Highly homogeneous and monodispersed macromolecules obtained by controlled polymerization have successfully been used for this purpose. However, disaggregation of the organized macromolecules is desired when a bioactive element, such as α-tocopheryl succinate, is introduced in self-assembled NPs and this element must be exposed or released to exert its action. The aim of this work is to demonstrate that the bioactivity of synthetic NPs based on defined reversible addition-fragmentation chain transfer polymerization copolymers can be enhanced by the introduction of hydrophilic comonomers in the hydrophobic segment...

The retinal fractal dimension (FD) is a measure of vasculature branching pattern complexity. FD has been considered as a potential biomarker for the detection of several diseases like diabetes and hypertension. However, conflicting findings were found in the reported literature regarding the association between this biomarker and diseases. In this paper, we examine the stability of the FD measurement with respect to (1) different vessel annotations obtained from human observers, (2) automatic segmentation methods, (3) various regions of interest, (4) accuracy of vessel segmentation methods, and (5) different imaging modalities...
