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 (...

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...

This study investigated the effects of voluntary wheel running on the myosin heavy chain (MHC) composition of the soleus (Sol) and plantaris muscles (Pla) in rats developing under hypobaric choronic hypoxia (CH) conditions during 4 wk in comparison with those of control rats maintained under local barometric pressure conditions (C) or rats pair-fed an equivalent quantity of food to that consume...

We hypothesized that a shift in muscle fiber type induced by clenbuterol would change monocarboxylate transporter 1 (MCT1) content and activity of lactate dehydrogenase (LDH) and isoform pattern and shift myosin heavy chain (MHC) pattern in soleus (Sol) and extensor digitorum longus (EDL) of male rats. In the clenbuterol-administered rats (2.0 mg x kg(-1) x day(-1) subcutaneously for 4 wk), the...

BACKGROUND Women with thermal discomfort from cold extremities (hands and feet; TDCE) often suffer from prolonged sleep onset latency (SOL). Suppressed anger could contribute to the genesis of both TDCE and prolonged SOL. The aim of the study was to test the hypothesis whether stereotypic feminine gender socialization (SFGS) is related to anger suppression (experienced anger inwards, Anger-In),...

Controlled nuclear fusion is the most promising candidate for being an inexhaustible, clean and intrinsically safe energy source. Research in the last 60 years has focused on the fusion reactor concept called tokamak, in which a high temperature plasma is confined using magnetic fields, producing fusion reactions. Because of turbulence, the confined plasma diffuses to the outermost region of th...
