We examined skeletal and cardiac muscle responses of mature (8 mo) and old (23 mo) male Fischer 344 rats to 14 days of hindlimb suspension. Hexokinase (HK) and citrate synthase (CS) activities and GLUT-4 glucose transporter protein level, which are coregulated in many instances of altered neuromuscular activity, were analyzed in soleus (Sol), plantaris (PI), tibialis anterior (TA), extensor dig...

The focus is on the oxidation resistance and tribological performance of ta-C Al2O3/ta-C coatings. wear tests were carried out ball disc tribometer at room (25 °C) high (400, 450 500 temperatures in ambient air with Si3N4 balls as counterbodies. Scanning electron microscopy Raman spectroscopy used to analyze surface morphology chemical bonding, respectively. coating exhibited better elevated th...

BACKGROUND The Website Developmental Model for the Healthcare Consumer (WDMHC) is an extensive and successfully evaluated framework that incorporates user-centered design principles. However, due to its extensiveness its application is limited. In the current study we apply a subset of the WDMHC framework in a case study concerning the development and evaluation of a website aimed at childhood ...

Objectives: The chondrotoxic effects of methylprednisolone acetate (MP) and triamcinolone acetonide (TA) have been well described. Prior studies demonstrated a dose-dependent effect intra articular (IA) steroids starting at 7 mg for MP 18 TA. However, the these on mechanical properties cartilage are largely unknown. purpose this study was to investigate in vitro single one-hour or TA exposure v...

Caching is an appropriate and well-known approach for reducing data transmissions in distributed information systems by creating and maintaining redundant data. As cache memory is limited and cached data might get outdated, it is impossible to store everything forever. If a cache is full, a replacement strategy decides on the cache entry that needs to be replaced by new data. There exist variou...

Teaching Assistants (TAs) play an important role in supporting research-based instructional environments, yet the connection between TAs' pedagogical beliefs and instructional practices is not well understood. We build upon a broad foundation of research on the nature of pedagogical content knowledge to develop an analytic framework for characterizing how physics TAs both describe and enact the...

Metal-semiconductor Janus-like nanoparticles with the composition tantalum silicide-silicon (TaSi₂/Si) were synthesized for the first time by means of an evaporation method utilizing a high-power electron beam. The composition of the synthesized particles were characterized using high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), selective area electron diffracti...

Pectin methylesterase (PME) rapidly hydrolyzes pectin methylesters in cold break tomato juice to form methanol and to increase titratable acidity (TA). Within 30 min, the juice methanol concentration increased from 35 to over 400 lg g 1 while the pH dropped from 4.45 to 4.20. On average, cold break juice pH values were 0.21 U lower and TAs 12.4 leq g 1 higher than those for hot break juices pre...

Cellular DNA content was determined by flow cytometry on routinely processed paraffin sections of 61 primary and untreated transitional cell carcinomas of the urinary bladder, and correlated with tumour grade and stage and clinical follow up. All 16 (25%) grade 1 carcinomas were diploid and all 11 (20%) grade 3 tumours were aneuploid. The 34 (55%) grade 2 carcinomas comprised 13 (40%) diploid a...
