the cytotoxic chloroform fraction of euphorbia aellenii afforded two cycloartane type triterpenes — cycloart-25-en-3,24-diol (1) and 24-methylene-cycloartan-3-ol (2) — for the first time from this plant. preparation of cycloartane derivatives, 3, 24-o-diacetyl-cycloart-25-en as compound 3 and 3-o-acetyl-24-methylene-cycloartan (4) were conducted by acetylating of 1 and 2, respectively. the ...

conclusions despite the fact that abnormalities in p53 and p27kip1 may be involved in the development of oscc, their clinical significance in the studied population seems limited. further investigation on the combined p53/p27kip1 expression may be helpful in predicting the biologic behavior of this tumor. results p53 and p27kip1 expression were found in 28.57% (8 positive versus 20 negative) an...

Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...

Parkinson’s disease is the second most common age associated neuron degenerative disorder in developed societies. With the prevalence ranging from 41 per 100000 in the fourth decade of life to over 1900 per 100000 in people over 80 years of age.it characterized clinically by resting tremor, slowness of movement, rigidity and postural instability in the result of progressive loss of dopami...

Abstract Plants must cope with ever-changing temperature conditions in their environment. Suboptimal high and low temperatures stressful extreme induce adaptive mechanisms that allow optimal performance survival, respectively. These processes have been extensively studied at the physiological, transcriptional, (epi)genetic level. Cellular signalling cascades tolerance also involve post-translat...

introduction: increased oxidative stress is widely accepted to be a factor in the development and progression of alzheimer’s disease. triazine derivatives possess a wide range of pharmacological activities including anti-oxidative and anti-in.ammatory actions. in this study, we aimed to investigate the possible protective effect of 3-thioethyl-5,6-dimethoxyphenyl-1,2,4-triazine (tedmt) on h2o2-...
