Curcumin, exerts anti-neoplastic and anti-apoptotic activities in cancer cell lines and piperine is effective for enhancing the bioavailability of curcumin. Docetaxel is an antimicrotubule agent used for cancer treatment. The cytotoxicity and gene expression effects of curcumin-piperine carrying nanoparticles compared to docetaxel were investigated. A reliable strategy for enhancing poor solubility is encapsulation through methods like electrospray as in this study. The cytotoxic effects of nanoparticles and docetaxel on cells were determined with IC 50 values by xCELLigence real-time cell analyzer. The gene expression analysis was performed to evaluate the molecular genetic changes for cancer related genes. The genes related to cancer formation, invasion and progression such as AKT1, MYC, NOTCH1, IL6, JUN, EGFR, MAPK1, RARB, BCL2, CCND1, MAPK8, BIRC5, ESR1 revealed decreased expression in the nanoparticles group compared to docetaxel. The gene expression results of curcumin and piperine loaded nanoparticles revealed higher significant effects on MDA-MB-231 breast cancer cells in terms of cancer progression compared to docetaxel.
This study aimed to provide novel insights into the white matter (WM) microstructural properties ... more This study aimed to provide novel insights into the white matter (WM) microstructural properties of Attention Deficit/Hyperactivity Disorder (ADHD) subtypes by recruiting a relatively large sample of stimulant-naïve children and adolescents who had no comorbidity other than Oppositional Defiant Disorder and were homogenous according to the DAT1 gene polymorphism. A sample of 72 ADHD subjects and 24 controls aged 8-15 years were enrolled in the study. We applied tract-based spatial statistics to the DTI measures for obtaining fractional anisotropy (FA) and axial, radial diffusivity (AD, RD) measures to explore ADHD type-related differences in WM for the whole brain. Comparing ADHD-Combined group (ADHD-C) with the ADHD predominantly inattentive group (ADHD-I) we detected increased RD in several bilateral brain area and increased AD mostly in left side of the brain, including the body and splenium of the corpus callosum; the anterior and posteriors limbs of the internal capsule; the superior, anterior and posterior corona radiata; the posterior thalamic radiation; and the superior longitudinal fasciculus. Likewise, mostly in the overlapping brain areas, the ADHD-C group presented increased AD values than ADHD-RI. Significant differences among ADHD types could be a preliminary evidence that they have distinct microstructural properties. There were no significant differences in diffusivity between controls and both the ADHD group as whole or any ADHD subgroups.

However, this phenotype was not included in the DSM-5 because of the lack of robust neurobiological data. We aimed to assess the specific neurobiological underpinnings of individuals presenting ADHD-RI. We compared a sample of 301 subjects (101 ADHD-Combined; 50 ADHD-RI; 50 ADHD predominantly inattentive type and 100 typically developing subjects) aged 8-15 years, using a complete neuropsychological battery, molecular genetic data (DRD4 and DAT1 most studied polymorphisms) and functional MRI during a Go-No/Go task. Subjects with ADHD-RI had a significantly different neuropsychological profile compared with the other groups, including lower psychomotor speeds, longer reaction times and the worst overall performance in the global neurocognitive index....
