Five different 2,2-disubstituted 4-acylthio-3-oxobutyl groups have been introduced as esterase-labile phosphodiester protecting groups that additionally are thermolabile. The phosphotriesters 1, 2 and 3 were prepared to determine the rate of the enzymatic and non-enzymatic removal of such groups at 37 ºC and pH 7.5 by HPLC-ESI-MS. Additionally, 1H NMR spectroscopic ...

BACKGROUND: While Western literature has mostly reported the incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) after TKA with chemoprophylaxis, the Asian literature still has mostly reported the incidence without chemoprophylaxis. This may reflect a low incidence of DVT and PE in Asian patients, although some recent studies ...

Roentgen stereophotogrammetric analysis (RSA) is commonly used to assess prosthetic stability as a predictor of the long-term clinical outcome of new total hip systems. Although the RSA technique is very accurate, it may not be trivial to interpret migration rates into clinical outcome, as critical migration rates depend heavily on ...

Introduction:  In the case of inflammation, imbalance of iron homoeostasis is caused by increased retention of iron within cells of the reticuloendothelial system. Iron-restricted erythropoiesis occurs because of decreased availability of iron for haemoglobin (Hb) synthesis in erythroid progenitor cells. Deviations in reticulocyte haemoglobin (Ret-He) content are investigated together with ...
