The purpose of the present study was to compare the therapeutic effects of risedronate (RIS) and alfacalcidol (ALF) on cancellous and cortical bone in ovariectomized osteopenic rats. Forty-two female Sprague-Dawley rats, 7 months of age, were randomized by the stratified weight method into six groups: the sham-operated control (Sham) group, and five ovariectomized groups: treated with vehicle, ...

OBJECTIVES To compared the effects of risedronate (Ris) and calcitriol (Cal) on cancellous bone in rats with glucocorticoid (GC)-induced osteopenia. MATERIALS AND METHODS Thirty female Sprague-Dawley rats, 4 mo of age, were randomly divided by the stratified weight method into three groups of 10 rats each according to the following treatment schedule: 8-wk GC administration with 4-wk vehicle ...

Diagonalization of uncertainty matrix and minimization of Robertson inequality for n observables are considered. It is proved that for even n this relation is minimized in states which are eigenstates of n/2 independent complex linear combinations of the observables. In case of canonical observables this eigenvalue condition is also necessary. Such minimizing states are called Robertson intelli...

OBJECTIVE RIS-1/psoriasin/S100A7 is an epithelial antimicrobial peptide, whose expression is upregulated in inflammatory skin diseases and is induced by retinoids. Its molecular expression was investigated in skin cell cultures and in skin specimens to better understand its role in inflammatory procedures of the pilosebaceous unit. METHODS rtPCR and northern blotting of RIS-1/psoriasin and th...

OBJECTIVES To describe a new technique, the reinforced interdental crossover composite splint (RIC), for transverse mandibular fracture repair in dogs. This technique was compared biomechanically with the established reinforced interdental Stout loop composite splint (RIS) technique. METHODS Six pairs of mandibles from young adult small breed dogs were used for the study. Osteotomies were cre...

This paper provides evidence on the significant impact of illiquidity or non-marketability on security valuation. A typical listed company in China has several types of share outstanding: (i) common shares that are only tradable on stock exchanges, (ii) restricted institutional shares (RIS) that are not tradable and can only be transferred privately or through irregularly scheduled auctions, an...

BACKGROUND Patients having chronic schizophrenia with frequent relapses and hospitalizations represent a great challenge, both clinically and financially. Risperidone long-acting injection (RIS-LAI) has been the main LAI atypical antipsychotic treatment in Greece. Paliperidone palmitate (PP-LAI) has recently been approved. It is dosed monthly, as opposed to biweekly for RIS-LAI, but such advant...

Nanocrystalline hydroxyapatite containing selenite ions (SeHA; 9.6 wt.% of selenium) was synthesized using wet method and subject to careful physicochemical analysis by powder X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, solid-state nuclear magnetic resonance, wavelength dispersive X-ray fluorescence, and inductively coupled plasma optical emissi...

A study of the process timing and organization has been done in a Radiology Department where Radiology Information System (RIS) and Picture Archiving and Communication System (PACS) are working. The workflow times have been directly read from RIS database. In particular, Execution and Reporting steps were considered. Afterwards, data have been analyzed through a statistical elaboration and resu...

Resonance Ionization Spectroscopy (RIS) technique is an ultrasensitive method of detection of atoms and molecules. Application of RIS to material analysis requires an atomization step which is based in our set-up on ion beam sputtering. We present a review of the analytical studies we have performed demonstrating the very attractive potentialities of this method. RIS can be also used to study t...
