Implantation-produced structural damage in InxGa1−xN

Expression profile of developmentally important genes in pre- and peri-implantation goat embryos produced in vitro

Background Little is understood about the regulation of gene expression during early goat embryo development. This study investigated the expression profile of 19 genes, known to be critical for early embryo development in mouse and human, at five different stages of goat in vitro embryo development (oocyte, 8-16 cell, morula, day-7 blastocyst, and day 14 blastocyst). MaterialsAndMethods Stage-...

Implantation Damage Formation in GaN and ZnO

Molecular and structural damage to Escherichia coli produced by antibody, complement, and lysozyme systems.

The antibacterial action of antibody (normal and hyperimmune), complement, and lysozyme has been studied by correlating the ultrastructural and biochemical changes that they cause in smooth Escherichia coli. Both normal and hyperimmune antibody, in the absence of lysozyme, produced complement-dependent release, into the suspending medium, of 63 to 72% of the (32)P-labeled phospholipid and 74 to...

Specific chemical and structural damage to proteins produced by synchrotron radiation.

Radiation damage is an inherent problem in x-ray crystallography. It usually is presumed to be nonspecific and manifested as a gradual decay in the overall quality of data obtained for a given crystal as data collection proceeds. Based on third-generation synchrotron x-ray data, collected at cryogenic temperatures, we show for the enzymes Torpedo californica acetylcholinesterase and hen egg whi...

Structural Transcatheter Aortic Valve Implantation

Transcatheter aortic valve replacement (TAVR) has emerged as the treatment of choice among inoperable patients with symptomatic severe aortic stenosis and as a treatment alternative to surgical aortic valve replacement (SAVR) for high-risk surgical patients. Subsequently, the number of patients undergoing TAVR worldwide is steadily increasing and the complications related to valve implantation ...
