The study investigates how surgery during pregnancy, i.e., sham operation associated with embryo transfer, affects hypertensive phenotype in ISIAH rats genetically predisposed to hypertension. ISIAH rats born after maternal surgery at fourth day of pregnancy were compared with naturally conceived controls. Surgery during pregnancy in ISIAH rats caused acceleration of neurodevelopment in young offspring, as well as aggravating hypertension, suppressing exploratory activity, reducing hippocampal BDNF expression, and compensatory increasing of hippocampal neuronal density in adult ISIAH offspring. Maternal surgery during early pregnancy caused alterations in offspring phenotype in hypertensive ISIAH rat model.

Objective: The study investigates how IVC and ET affect hypertensive phenotype in ISIAH rats. Methods: ISIAH rats born as the result of ET and IVC were compared with naturally conceived controls. Results: Embryo transfer from hypertensive ISIAH rats to normotensive recipient dams caused lower SBP and DBP in the female offspring. When ET was accompanied with in vitro culture in R1ECM, not only the female offspring, but also males demonstrated alleviation of hypertension. Conclusions: IVC at the preimplantation embryo stage affected the manifestation of hypertension in the adult ISIAH offspring.

A simple original approach to earlier unknown parent 2,7-dihydrothiopyrano[2,3-b]pyrrole (5) from allyl isothiocyanate and propargyl bromide via one-pot synthesis and thermal rearrangement of 2-(prop-2-ynylsulfanyl)-1H-pyrrole (4) has been developed. The compound 5 in the present study was successfully examined as 2,7-dihydrothiopyrano[2,3-b]pyrrole scaffold in the synthesis of corresponding N- and C-pyrrolecarbodithioates.

2-(2,2-Dicyano-1-ethylsulfanylethenyl)pyrroles readily react (ethanol, reflux) with aniline at position 1 of the ethenyl moiety in the presence of triethylamine to eliminate ethanethiol affording 1-anilino-3-iminopyrrolizine-2-carbonitriles or 2-(1-anilino-2,2-dicyanoethenyl)pyrroles in good yields.

New composite material—multi-walled carbon nanotubes (MWCNTs) coated with thin iron films—have been prepared by MOCVD growth technique using iron pentacarbonyl as the iron source. Their structures and morphologies were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and thermal gravimetric analysis. The NEXAFS C1s- and Fe2p-spectra of the composite materials MWCNTs-pyrolytic Fe were studied by total electron yield mode with using synchrotron radiation Russian-Germany beamline at BESSY-II. The study has shown that top layers of the MWCNTs in composite do not have essential destruction, coating of MWCNT's-surface is Fe3O4 and this coating is continuous. The iron oxide adhesion is provided by chemical binding between the carbon atoms of the MWCNT's top layer and the oxygen atoms of the coating.

The reaction of pyrrole-2-carbodithioates with methylenoactive nitriles and 2-benzoyl-1-bromoacetylene in the KOH-DMSO system leads to functionally substituted pyrrolothiazoles in 59-85% yield.
