Two patients with a costoclavicular joint were discovered by chance during a survey of cervical spines. These seem to be the first to be described in the radiological literature. No other case was found in a further review of 500 consecutive spine radiographs. The costoclavicular joint is a variant of the ligamentous connection between the medial part of the clavicle and the first rib.

A model for the web consolidation process in the paper dryer is developed and compared with experimental data for the kraft pulps. The model contains one parameter called the shrinkage factor which is used as the fitting parameter to the experimental data. The shrinkage factor can have a value between zero implying no shrinkage and a value of one which implies that all the liquid volume removed le

We propose an inherently origin invariant formulation of specific optical rotation obtained from the conventional velocity gauge expression by subtracting the static limit from the electric dipole-magnetic dipole polarizability: <<(p) over right arrow, (L) over right arrow >>(omega) --> <<(p) over right arrow, (L) over right arrow >>(omega) - <<(p) over right arrow, (L) over right arrow >>(0).

We have implemented a non-null type checker for Java and a new non-null inferencing algorithm for analyzing legacy code. The tools are modular extensions to the JastAdd extensible Java compiler, illustrating how pluggable type systems can be achieved. The resulting implementation is compact, less than 230 lines of code for the non-null checker and 460 for the inferencer. Non-null checking is a loc

Electrochemical CV and SWV studies were performed with double stranded DNA from salmon testes (dsDNA) and single stranded DNAs, containing 25 nucleotides (ssDNA) directly adsorbed at polycrystalline An electrodes. A distinct oxidation peak at + 730 mV (SWV, scan rate 0.248 V s(-1)) or at + 730 - + 780 mV (CV, scan rate from 0.3 to 1 V s(-1)) was obtained with DNA-modified Au electrodes after a tim

The advantages of using a detailed mathematical model for fixed bed chromatography is demonstrated by the personal computer program SIMCHROM. The chromatography model includes axial dispersion in the bulk liquid, external and internal mass transfer resistances and an instationary non-linear adsorption model. Frontal and pulse chromatography can be studied for single and multicomponent systems. The

The reactive vascular-injuring amino acid homocysteine was previously shown to be increased in plasma in diabetic patients with clinical signs of nephropathy. In this study, plasma homocysteine was measured in type 1 diabetic patients with normoalbuminuria (n = 22), microalbuminuria (n = 40) and proteinuria (n = 14) in order to investigate whether plasma homocysteine levels are increased already a

Background: Soluble E-selectin (sE-selectin) is a marker of activation of vascular endothelium. Objective: To examine serum levels of sE-selectin in a cohort of 85 patients with early rheumatoid arthritis (RA) followed up for five years. Methods: sE-selectin levels were assessed annually using an enzyme linked immunosorbent assay (ELISA) and related to simultaneously obtained clinical and laborato

2-Bromoethyl glycosides can easily and in high yields be transformed into sulfones by treatment with a suitable thiol followed by oxidation with mCPBA. The observation that the so formed sulfones were cleaved by treatment with NaOMe/MeOH was used to design a new safety catch linker for synthesis of glycoconjugates on solid support.

This study established the reliability of a novel upper-limb trajectory-tracking task for assessment of perceptual motor control in hemiparetic adults. Eleven persons with chronic poststroke hemiparesis (mean 58.6 months) and eleven nondisabled control subjects performed an elbow flexion-extension task against a low-resistance isotonic load at three speeds: 25degrees/s, 45degrees/s, and 65degrees/
