Highlights 2  Single phase LaTi2Al9O19 (LTA) has been successfully synthesized by sol-gel method at relatively low temperature (1350 o C), something not previously investigated.  The sol-gel synthesized LTA shows good thermochemical stability up to 1500 o C.  Sol-gel synthesized LTA shows higher coefficients of thermal expansion than the solid state reaction synthesized LTA.  LTA is a face ...

BACKGROUND Emergency department thoracotomy (EDT) has become standard therapy for patients who acutely arrest after injury. Patient selection is vitally important to achieve optimal outcomes without wasting valuable resources. The aim of this study was to determine the main factors that most influence survival after EDT. STUDY DESIGN Twenty-four studies that included 4,620 cases from institut...

The molecular composition and drug responses of calcium-activated K(+) (BK) channels of skeletal muscle are unknown. Patch-clamp experiments combined with transcript scanning of the Kcnma1 gene encoding the alpha subunit of the BK channel were performed in rat slow-twitch soleus (Sol) and fast-twitch flexor digitorum brevis (FDB) skeletal muscles. Five splicing products of the Kcnma1 gene were ...

the silica supported platinum nanoparticles was synthesized by using the sol-gel method. the possibility of using diamminedinitro platinum (ii) as pt precursor and effect of metal precursor concentration on the final pt nanoparticle size was investigated. a stable silica sol was prepared via hydrolysis of tetraethyl orthosilicate (teos) as a metal alcoxide and condensation reaction. subsequentl...

Immunocytochemical characteristics of myosin have been demonstrated directly in normal and cross-reinnervated skeletal muscle fibers whose physiological properties have been defined. Fibers belonging to individual motor units were identified by the glycogen-depletion method, which permits correlation of cytochemical and physiological data on the same fibers. The normal flexor digitorum longus (...

La1-xSrxAlO3-δ (x = 0, 0.1, 0.15) fine particles were prepared by the Pechini process using citric acid and ethylene glycol at low temperature 900 °C. The powders were studied by several physical characterization techniques. The FTIR spectrum of the resin treated at 200 °C revealed the formation of a metalorganic complex and a polymerized form of ethylene glycol. XRD spectra of the samples, cal...

Magnetic and electric properties are investigated for the nanosized YMnO3 samples with different grain sizes (25 nm to 200 nm) synthesized by a modified Pechini method. It shows that magnetic and electric properties are strongly dependent on the grain size. The magnetic characterization indicates that with increasing grain size, the antiferromagnetic (AFM) transition temperature increases from ...

I. Force transducers designed for chronic implantation were placed on the individual tendons of the medial gastrocnemius (MG) and soleus (SOL) muscles in the same hindlimb of adult cats. Electromyographic (EMG) and kinesiological data were also recorded. Force, EMG, and movement data obtained from intact, freely moving cats illustrate the division of labor between the mixed MG and its slow-twit...
