The analysis of physical properties connected to the electron spin in terms of spin densities requieres some caution : i) Spin densities cannot be always calculated or discussed in the frame of standard independentparticle model (as the restricted Hartree-Fock theory), neither in the frame of amended spin-unrestricted independent particle models. The former/ neglecting spin-polarization effects...

The synthesis of sterically hindered persistent sila- and germacyclopentadienyl radicals adds magnetic properties to these heterocyclic ring systems sparks the idea their possible application as building blocks for molecular magnets (pictured red-blueish northern light). Support comes from analysis EPR spectroscopic parameters computed spin density - shown here silicon species that indicate loc...

OBJECTIVES To determine whether data obtained from patients returning postal questionnaires accurately reflect how patients receiving imaging-guided lumbar facet injections respond. METHODS Seventy-eight patients receiving lumbar facet joint injections who returned an outcomes questionnaire (responders) were age and gender matched with 78 patients who did not return the postal questionnaire (...

BACKGROUND In direct techniques of flow cytometry, the optimal antibody dilution or titer point is established from the plateau area of the antibody titration curve. However, the plateau area is defined without any statistical criteria, which may lead to an incorrect selection of antibody dilution. Herein, we report statistical criteria to establish the optimal antibody dilution for CD14, CD8, ...

Two Cobas-Bio analyzers were found to have significantly increased imprecision, owing to absorbance errors, when we used rotors pieced together from segments of four to 10 cuvets. The difference in CV between whole/unbroken and four-cuvet or 10-cuvet segment rotors was significant by Student's unpaired t-test (P = 0.038 and less than 0.0001, respectively) and by the Mann-Whitney U test (P less ...

BACKGROUND It has been recently reported that local injection of autologous blood in tennis elbow offers a significant benefit by virtue of various growth factors contained therein. The objective of our study was assessment of efficacy of autologous blood injection versus local corticosteroid injection in the treatment of tennis elbow. METHODS AND TRIAL DESIGN A single blinded, prospective pa...

PURPOSE The aim of the present study was to compare macular thickness in patients with keratoconus (KC) with macular thickness in healthy subjects. SUBJECTS AND METHODS Twenty-six patients with KC and 52 control subjects were included. The macular structure was evaluated using a Zeiss Cirrus HD-OCT. The scan pattern used was 512 × 128, which covers an area of approximately 6 × 6 mm of the ret...

Aspirin, which inhibits mucin secretion in the gastrointestinal tract prevents gall stone formation in animals and may reduce gall stone recurrence in man. This study examines the effect of aspirin on mucin synthesis in human gall bladder explants. Two hundred explants were cultured with 3H-glucosamine (74 kBq/ml) for 24 hours at 37 degrees C. Mucin and other glycoproteins were isolated by papa...

PURPOSE To quantitatively assess and compare the anterior chamber volume (ACV) by different anterior segment imaging techniques. METHODS Forty healthy eyes of 40 patients were recruited and three consecutive measurements of ACV were determined prospectively utilizing SL-OCT and Pentacam. Statistical significance of interdevice differences between measurements was evaluated by unpaired t test ...
