{Tc(NO)(Cp)(PPh3)}+ – a novel technetium(I) core
Reactions between [TcI(NO)X2(PPh3)2(CH3CN)] complexes (X = Cl, Br) and KCp
form the pseudotetrahedral organotechnetium compounds [TcI(NO)(Cp)(PPh3)X].
The halide ligands can readily be replaced by other halides or organometallic
ligands giving access to a novel family of technetium(I) compounds with the
robust {Tc(NO)(Cp)(PPh3)}+ core
Echocardiographic diagnosis of a cardiac fibrosarcoma in the right atrium of a sheep
This is a case report of a six-year-old female White Alpine sheep with a cardiac fibrosarcoma in the right atrium. Clinically, the sheep had right-sided cardiac insufficiency with tachycardia, engorgement of the jugular veins, brisket edema, and ascites. Chronic congestion of the liver resulted in increased hepatic enzyme activity. Based on clinical findings, a tentative diagnosis of endocarditis or pericarditis was made. Radiography of the thorax revealed hydrothorax. An echogenic mass was observed in the right atrium via echocardiography; it was interpreted as a tumor or thrombus. Ultrasonography of the abdomen revealed severe ascites and chronic congestion of the liver attributable to right-sided cardiac insufficiency. The clinical and sonographic findings were verified at post mortem. The mass in the right atrium was a pedunculated fibrosarcoma
