In the title compound, C(18)H(17)NO(4), the hy-droxy-ethanimine group is essentially coplanar with the ring to which it is attached [C-C-N-O torsion angle = 179.94 (14)°]. The mol-ecules are linked into cyclic centrosymmetric R(2) (2)(6) dimers via O-H⋯N hydrogen bonds and the crystal packing is further stabilized by C-H⋯O inter-actions.

Catalytic distillation is a technology that combines heterogeneous catalytic reaction and the separation of reactants products via in single reactor/distillation system. This process catalysis, kinetics, mass transfer to obtain more selective products. The catalyst provides sites for reactions porous surface liquid/vapor separation. advantages are energy savings, low waste streams, longevity, h...

BACKGROUND Sex difference is an established risk factor for hematopoietic stem cell transplantation (HSCT)-related complications like graft versus host disease (GVHD). CD8pos cytotoxic T cells specific for Y chromosome-encoded minor Histocompatibility antigens (HY) play an important role therein. Prior to HSC donation, female donors may encounter HY antigens through fetomaternal or transmaterna...

We undertook a comparative study of the effects of the hormone hydrocortisone (Hy) on C6 glioma cells grown in monolayer and in suspension in cultures. We found Hy reversibly renders C6 cells anchorage- and serum-dependent for their growth. In monolayer cultures, Hy was found to inhibit cell cycle traversing exclusively at G1 phase. In agarose suspension, Hy was found to block colony developmen...

Three human IFN-alpha hybrids, HY-1 [IFN-alpha21a(1-75)/alpha2c(76-165)], HY-2 [IFN-alpha21a(1-95)/alpha2c(96-165)], and HY-3 [IFN-alpha2c(1-95)/alpha21a(96-166)], were constructed, cloned, and expressed. The hybrids had comparable specific antiviral activities on Madin-Darby bovine kidney (MDBK) cells but exhibited very different antiproliferative and binding properties on human Daudi and WISH...

Photolysis into the longest wavelength absorption band of 2-tert-butyl-2,3-diazabicyclo[2.2.2]oct-3-yl hydrazine (Hy) substituted naphthalenes causes aryl group reduction electron transfer to give (+)Hy-Ar(-). Electrooptical absorption measurements characterize the charge separation properties from these bands. Emission studies demonstrate that the separation between absorption and emission max...

An electroanalytical method has been introduced for highly sensitive determination of hydralazine hydrochloride (Hy-HCl) based on its oxidation at a glassy carbon electrode modified with multiwalled carbon nanotubes (MWCNT/GCE). Studies showed that the electrochemical oxidation of Hy-HCl was accompanied by adsorption and highly sensitive responses could be achieved by adsorptive stripping volta...

With the launches of HY-2B, HY-2C and HY-2D, National Satellite Ocean Application Service (NSOAS) successfully established first batch HY-2 constellation on 19 May 2021, dedicated to detecting marine dynamic environment. While validation calibration series satellites have been well studied, using both in situ cross-track measurements, further evaluation is required mapping capability mesoscale ...
