Purpose: Trophoblastic cancers (Choriocarcinoma, testicular and ovarian germ cell malignancies) secrete hyperglycosylated hCG and non-trophoblastic cancers secrete hyperglycosylated hCG free βsubunit.Both are structural variants of hCG independent to the hormone hCG. They are autocrines acting on a transforming growth factor β-II (TGF-β-II), receptor not acting on the hormone receptor. Here the...

the present study explores the chemical constitution and antioxidant activity of the essential oils of the aerial parts of artemisia dracunculus l. and the flower heads of matricaria chamomilla l. gc-ms analysis revealed the presence of (z)-anethole (51.72%), (z)-β-ocimene (8.32%), methyleugenol (8.06%), limonene (4.94%) and linalool (4.41%) in artemisia dracunculus and (e)-β-farnesene (24.19%)...

Salvia reuterana Bioss. is an aromatic perennial plant traditionally used for its anxiolytic and sedative properties. In the present study, various fractions and essential oil of S. reuterana aerial parts were investigated to find its free radical scavenging principles. Hydroalcoholic fraction with IC50 value of 112.6 ±3.2 μg ml-1 in DPPH assay demonstrated the highest free radical scavenging a...

Cationic β-C–H and β-C–C scissions were employed for selective cationic dimerization of α-methylstyrene (αMS) derivatives to synthesize exo-olefin compounds subsequent sulfur-free RAFT polymerization αMS isobutylene (IB) produce polymers with controlled structures, respectively, as reported by Masami Kamigaito et al. in their Research Article (e202307791).

background & aim: essential oils are isolated from different sections of plants such as flowers, seeds, leaves, stems and roots. essential oils are applied extensively in producing of perfumes, cosmetics, foods, beverages and confectioneries and as ingredients of disinfectants and insecticides. experimental: essential oil are obtained by several isolation methods, such as hydrodistillation ...

BACKGROUND The effect of alcohol consumption on prostate health and reproductive hormone profiles has long been investigated and currently, no consensus has been reached. Additionally, large studies focusing on this topic are relatively rare in China. PURPOSE To investigate the association of alcohol consumption with prostate measurements and reproductive hormone profiles in Chinese populatio...

Oxalic acid dihydrate as a green, mild and efficient catalyst for the one-pot three-component Biginelli synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives from the reaction between β-keto esters (methyl or ethyl acetoacetate), aromatic aldehyde (benzaldehye derivatives) and urea or thiourea under thermal and solvent-free conditions with excellent yields and short reaction time is st...
