We report three cases of atlanto-axial rotatory fixation in adults. Early diagnosis was made by clinical tests showing restricted head rotation in maximal neck flexion and asymmetry of the transverse processes of the atlas, confirmed by cineradiography. Early treatment by traction may obviate long-term problems of torticollis and instability.

Formation of T-Hg(2+)-T complexes changes the configuration of a single-stranded DNA, leading to enhanced fluorescence of an anchored cyanine-based probe that displays restricted intramolecular rotation (RIR)-induced emission. This label-free system can be used as a sensor for mercury ions with a detection limit of 4 nM.

Two new GdEGTA (EGTA = ethylene glycol-bis(2-aminoethylether)-N,N,N',N'-tetraacetic acid) derivatives incorporating aromatic moieties into the oxoethylenic bridge have been prepared and characterised, their conjugates to HSA investigated and an unprecedented high relaxivity, close to that predicted by theory, interpreted in terms of the combined effect of restricted local rotation and fast rate...

Yet each in itself – this was the uncanny, the antiorganic, the life-denying character of them all – each of them was absolutely symmetrical, icily regular in form. They were too regular, as substance adapted to life never was to this degree – the living principle shuddered at this perfect precision, found it deathly, the very marrow of death – Hans Castorp felt he understood now the reason why...

Gender differences in a psychometrical and in a chronometrical mental rotation test and in a standardized math test were investigated with a sample size of 109 boys and girls aged 7 or 8 years. The results revealed gender differences in all accuracy-based measures, i.e., in the paper-pencil mental rotation test, in the math test, and in the error rate of the chronometrical test. In line with th...

The Tamari lattice of order n can be defined on the set Tn of binary trees endowed with the partial order relation induced by the well-known rotation transformation. In this paper, we restrict our attention to the subset Mn of Motzkin trees. This set appears as a filter of the Tamari lattice. We prove that its diameter is 2n − 5 and that its radius is n − 2. Enumeration results are given for jo...

We used five randomly selected cadaver specimens to evaluate the Anderson Knee Stabler and the Lenox Hill Knee Brace, individually and in combination with an anterior cruciate ligament protective tape method. Reduction of total laxity, as well as a defined pathologic anterior-posterior translation and internal-external rotation, was tested after the anterior cruciate and medial collateral ligam...

This research introduces compressed sensing (CS) principle into inverse synthetic aperture radar (ISAR) imaging of nonuniform rotation targets, and high azimuth resolution can be achieved with limited number of pulses. Firstly, the sparsity of the echoed signal of radar targets with non-uniform rotation in certain matching Fourier domain is analyzed. Then the restricted isometry property (RIP) ...

OBJECTIVE After reverse shoulder arthroplasty (RSA) external and internal rotation will often remain restricted. A postoperative alteration of the biomechanics in the remaining cuff is discussed as a contributing factor to these functional deficits. METHODS In this study, muscle moment arms as well as origin-to-insertion distance (OID) were calculated using three-dimensional models of the sho...
