First measurement of the transverse spin asymmetries of the deuteron in semi-inclusive deep inelastic scattering.

First measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarized 6LiD target are presented. The data were taken in 2002 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. The Collins asymmetry turns out to be compatible with zero, as does the measured Sivers asymmetry within the present statistical errors.

A case of sinus pause due to the proarrhythmia of pilsicainide.

A 74-year-old man received oral administration of pilsicainide, a pure sodium channel blocker with slow recovery kinetics, to convert paroxysmal atrial fibrillation to sinus rhythm and developed loss of consciousness two days later. The ECG monitoring revealed sinus pause with markedly prolonged PQ interval and QRS width. Two days after the drug was discontinued, the duration of the QRS complex was normalized.

Exercise induced atrioventricular block with gap phenomenon in atrioventricular conduction.

A 54-year-old man with normal atrioventricular (AV) conduction at rest gave a 4-year history of presyncope during exercise. Treadmill testing showed exercise induced AV block. Electrophysiological study demonstrated rate dependent infranodal AV block and abnormal refractory period of the His-Purkinje system.

In vitro examination of the safety of rotational atherectomy of side branches jailed by stents.

In vitro experimental models of branch orifices jailed by various stents were created to estimate the safety and the efficacy of rotational atherectomy when rotational burrs were advanced through the struts of stents. The scaffolding structures of the stents were destroyed due to loss and deflection of the struts, and the size of ablated stent-particles differed: the maximal size was 1.7 mm in slotted stents, and 17.

An autopsied case of acute myocarditis with myocardial calcification.

A 47-year-old woman was admitted with fever, hypotension, an elevated serum creatinine kinase level, and electrocardiographic abnormalities, which led to the diagnosis of acute myocarditis. She was placed on percutaneous cardiopulmonary support because of hemodynamic collapse on the third hospital day. Serial echocardiography showed gradual recovery of profound hypokinesis and edematous thickening of the left ventricle, but she died of sepsis on the 17th day without overt renal insufficiency or electrolytic abnormalities.
