Mobility of cervical spine and postural equilibrium in patients with spinal overload syndrome.

Background: The spinal overload syndrome develops as a result of the gradual wearing away of the structural elements of the spine due to loads exceeding their endurance strength in the setting of reduced adaptability. The aim of the investigation was to study the limitation of mobility in the cervical spine and determine the effect of the spinal overload syndrome on postural equilibrium.

Material And Methods: The study enrolled 27 patients with signs of overload of the cervical spine.

Method of determination of emission properties of very weakly emitting species ensuring elimination of emission of impurities.

This paper describes a new type of spectrofluorimeter, composed of a high-performance liquid chromatography (HPLC) system directly connected to a fluorescence detector and an absorption photodiode array detector, designed for studying the emission of weakly emitting species. Procedures for measurements of emission spectra (ES), emission excitation spectra (EES), and quantum yields of emission (PhiE) for very weakly emitting systems (PhiE>or=10(-7)) have been proposed. The original methodical solution allows verification of whether the emission observed comes solely from the compound studied (and not from its impurities) or from some photochemical or thermal process taking place during measurements.

The prevalence of erectile dysfunction in men visiting outpatient clinics.

The prevalence of erectile dysfunction (ED) in men visiting outpatient clinics was analyzed using data reported by 1352 randomly chosen physicians who were requested to interview five to 20 consecutive patients aged >or=40 years about the presence of ED. A total of 25.12% of the physicians returned the questionnaires, containing data on 3552 patients, of whom 42.
