We present the first successful case of living donor liver transp

We present the first successful case of living donor liver transplantation using a donor with asymptomatic protein S deficiency. Interestingly, whereas the donor continued to have protein S levels approximately 50% of normal, the recipient maintained normal levels of protein S post-transplant, potentially due to compensation by extra-hepatic protein S production. We discuss the prior literature of protein S deficiency acquired via liver transplantation, and we evaluate potential criteria by which the safety of transplants utilizing this pool of donors may be enhanced.”
“A study CFTRinh-172 mw on the effect of secondary electron emission, which strongly affects

the detection of extreme-UV radiation, was performed on diamond detectors. Two different structures were compared: interdigitated contacts and a transverse Schottky diode configuration. Both devices were electrically characterized by I-V measurements and their responsivity was measured Selleck IPI-145 in the extreme UV spectral region (20-120 nm) by using He-Ne gas discharge radiation sources and a toroidal grating vacuum monochromator. Through an ad-hoc

measurement configuration, the contributions of the internal photocurrent and of the photoemission current have been analyzed and separately evaluated. The results showed that secondary electron emission, which clearly depends on the experimental conditions (e. g., external electric field, pressure, etc.), is one of the most relevant processes affecting the spectral responsivity LB-100 nmr in the extreme UV band. In particular, for interdigitated devices, extreme care must be taken in order to obtain an absolute value of their responsivity, while detectors in the transverse configuration can be shielded in such a way to avoid secondary electron current contribution and therefore provide a more correct and reliable response.

“Pellet manufacturing

by extrusion/spheronization is quite common in the pharmaceutical field because the obtained product is characterized by a high sphericity as well as a narrow particle size distribution. The established mechanisms only consider deformation of the initially fractured particles but do not account for mass transfer between the particles as a factor in achieving spherical particles. This study dealt with the visualization of mass transfer during spheronization. Therefore, two common pelletization aids, microcrystalline cellulose and kappa-carrageenan, were used alone as well as in combination with lactose as a filler. This study proves that mass transfer between particles must be considered in addition to plastic deformation in order to capture the spheronization mechanism.
