The radial velocity method is amongst the most robust and established means of detecting exoplanets. Yet, it has so far failed to detect circumbinary planets despite their relatively high occurrence rates. Here, we report velocimetric measurements Kepler-16A, obtained with SOPHIE spectrograph, at Observatoire de Haute-Provence's 193cm telescope, collected during BEBOP survey for planets. Our ma...

Trithiolato-bridged dinuclear ruthenium(II)-arene complexes are active against various parasites including Toxoplasma gondii. Lipids, isoprenoids and lipoate metabolites scavenged by T. gondii from the host cell but also synthesized parasite, these molecules can be appended to diruthenium moiety in a conjugate approach aiming at compounds with improved antiparasitic activity selectivity. The sy...

2-Phosphanyl-substituted imidazolium salts 2-PR2(4,5-Cl-Im)[OTf] (9a,b[OTf]) (4,5-Cl-Im = 4,5-dichloro-1,3-bis(2,6-di-isopropylphenyl)-imidazolium) (a: R = Cy, b: R = Ph) are prepared from the reaction of R2PCl (R = Cy, Ph) with NHC 8 (4,5-dichloro-1,3-bis(2,6-di-isopropylphenyl)-imidazolin-2-ylidene) in the presence of Me3SiOTf. 5-Phospanyl-substituted imidazolium salts 5-PR2(2,4-Cl-Im)[OTf] (...

Microsomal epoxide hydrolase, a major antigenic marker of putative preneoplastic hepatocytes was studied in hyperplastic liver nodules and in normal liver tissue. Hyperplastic nodules induced by two different protocols contained 2to 3-fold higher specific activities of microsomal epoxide hydrolase than did normal surrounding tissue. However, no increase in cytosolic epoxide hydrolase determined...

The key step in the synthesis of the 7,9-diazabicyclo[4.2.2]decane system was a modified Dieckmann condensation of piperazinebutyrate 11, which makes use of trapping the first cyclized intermediate with TMS-Cl. Reduction of the bicyclic ketone 14 with LiBH(4) at -90 °C provided diastereoselectively (>99 : 1) the syn-configured alcohol 15a, which was converted into the final alcohol and ethers 1...

BACKGROUND 1-chloro-4-[2,2,2-trichloro-1-(4-chlorophenyl)ethyl]benzene (p,p'-DDT) is a persistent environmental endocrine disruptor (ED). Several studies have shown an association between p,p'-DDT exposure and reproductive abnormalities. OBJECTIVES To investigate the putative effects of p,p'-DDT on the human follitropin receptor (FSHR) function. METHODS AND RESULTS We used Chinese hamster o...
