BACKGROUND Higher-level gait disorder (HLGD) in older adults is characterized by postural instability, stepping dysrhythmicity, recurrent falls and progressive immobility. Cognitive impairments are frequently associated with HLGD. OBJECTIVES The aim of this study was to compare gait and cognitive performance before and after the use of rivastigmine in patients with HLGD, free from cognitive i...

In the title salt, C23H26F3N2OS(+)·C4H5O6 (-) [systematic name: 1-(2-hy-droxy-eth-yl)-4-[3-(2-(tri-fluoro-meth-yl)thioxanthen-9-yl-idene)prop-yl]piperazin-1-ium 3-carb-oxy-2,3-di-hydroxy-pro-pion-ate], the monoprotonated piperazine ring in the cation adopts a chair conformation, while the thio-pyran ring of the thioxanthene group has a boat conformation. The dihedral angle between the mean plan...

-Competitive adsorption between phosphate, tartrate and oxalate was studied on two hydroxy aluminum montmorillonite complexes (A1Mtl.6 and AIMt6), which were prepared by adding a base to pH 5.5 to samples containing 1.6 and 6.0 mol AI per kg clay. The quantities of phosphate, tartrate and oxalate adsorbed were more closely related to the amount of OH-AI species coatings on the montmorillonite t...

BACKGROUND Bone changes are common in sickle cell disease, but the pathogenesis is not fully understood. Tartrate-resistant acid phosphatase (TRACP) type 5b is produced by bone-resorbing osteoclasts. In other forms of hemolytic anemia, increased iron stores are associated with osteoporosis. We hypothesized that transfusional iron overload would be associated with increased osteoclast activity i...

In this work, acoustic, thermal, and optical properties were tested on the different concentrations of Disodium Tartrate solutions. First, viscosity studies analyzed for tartrate in concentration range from 2% to 20% with temperatures 303K, 308K, 313K, 318K. It was noted that relative activation energy prepared compound increase increases decreases temperature increases. The like density ultras...

In this study, the preservation of As(III) in model solutions and natural groundwater samples from four locations Croatia was conducted. Model laboratory were spiked with As(V), different complexing agents. Solutions analysed intervals 24, 48 h during ten days after preparation. containing citric acid, sodium citrate, oxalate potassium tartrate combination acetic As(III)and showed good species ...

IN THE TITLE COMPOUND (SYSTEMATIC NAME (R)-dimeth-yl{2-[1-phenyl-1-(pyridin-2-yl)eth-oxy]eth-yl}aza-nium (R,R)-3-carb-oxy-2,3-dihy-droxy-propano-ate), C(17)H(23)N(2)O(+)·C(4)H(5)O(6) (-), the doxylaminium cation is protonated at the N atom. The tartrate monoanions are linked by short, almost linear O-H⋯O hydrogen bonds into chains extended along [100]. These chains are inter-linked by anion-pyr...

Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer’s disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug. The content of the drug was determined by High Performance Liquid Chromatography (HPLC) method. The morphology and size range of the microparticles ...
