The long fingers' paddlefish carpometacarpal (CMC) dislocation is exceptional. Most dislocations occur after high energy trauma. Untreated, these lesions can result in chronic instability of the CMC joints and early osteoarthritis. We report the case of a 20-year-old patient presenting with an ulnar paddlefish CMC fracture-dislocation of the three lesser fingers resulting from a hand trauma in ...

The effect of brushing with two abrasive levels on the fluoride release of high-viscosity glass ionomers (GIs) was investigated. Forty-eight GI discs were fabricated and randomly assigned to one of the four groups. Treatments, performed for 30 days, included exposure to a carboxymethylcellulose (CMC) solution without fluoride (CMC-F), CMC with 275 ppm fluoride (CMC+F), CMC with fluoride plus br...

The purpose of this study was to determine whether 4-chloro-m-cresol (4-CmC) could generate caffeine-like responses in ferret cardiac muscle. The concentration dependence of 4-CmC-mediated release of Ca(2+) from the sarcoplasmic reticulum was studied in intact cardiac trabeculae and saponin-skinned fibers in which the sarcoplasmic reticulum was loaded with Ca(2+). In intact and saponin-skinned ...

In this study, bisphasic calcium phosphate (BCP) and two types of polysaccharide, carboxymethyl cellulose (CMC) and hyaluronic acid (HyA), were used to fabricate composite block bone grafts, and their physical and biological features and performances were compared and evaluated in vitro and in vivo. Specimens of the following were prepared as 6 mm diameter, 2 mm thick discs; BPC mixed with CMC ...

The aim of the present study was to determine the effects of 4-chloro-m-cresol (4-CmC), a preservative often added to drugs intravenously administered, on the skeletal muscle sarcoplasmic reticulum (SR) Ca2+ release channel/ryanodine receptor. In heavy SR vesicles obtained from rabbit back muscles, 4-CmC stimulated (Ca2+)-activated [3H]ryanodine binding with an EC50 of about 100 microM. In the ...

Computer-mediated communication (CMC), such as email, instant messaging, and online texting, is an important channel for influencing message receivers’ behavior. While most communication media are structurally biased to support either interpersonal or broadcast modes of communication, CMC can support both. Because of this we argue that receivers are likely to comply with a CMC message based on ...

Computer-mediated communication (CMC) technologies, such as Instant Messaging (IM), the cell phone, and email have exploded, thus, creating fertile ground for innovative methods of communication. In this global environment, it is evident that innovative techniques must be employed to foster and sustain the mentor/protégé relationship. Using PLS as the analysis technique, we investigate the impa...

Graphene oxide nanosheets (GONs)/carboxymethyl chitosan (CMC)/Fe₃O₄ magnetic composite microspheres (MCMs) were prepared by enclosing Fe₃O₄ particles with CMC and GONs in turn. The microstructures of GONs and GONs/CMC/Fe₃O₄ MCMs were characterized by FTIR, XRD, TEM, and SEM. The effects of GON content, pH value, and adsorption time on the adsorption capacity of the MCMs were investigated. The r...

This study examines how computer-mediated communication (CMC) systems, e-mail, bulletin board, real time discussion and listserv, enhance and inhibit on-line interaction from four theoretical constructs and four different types of interaction. A comprehensive search of the ERIC database was conducted and the relevant studies were referenced for the discussion. Analysis reveals that CMC systems ...
