چکیده

Objective: To review the research literature published within the past 10 years regarding the impact of media on children and adolescents. Method: Media categories researched with computer technology included television and movies, rock music and music videos, advertising, video games, and computers and the Internet. Results: Research prior to 1990 documented that children learn behaviors and have their value systems shaped by media. Media research since has focused on content and viewing patterns. Conclusions: The primary effects of media exposure are increased violent and aggressive behavior, increased high-risk behaviors, including alcohol and tobacco use, and accelerated onset of sexual activity. The newer forms of media have not been adequately studied, but concern is warranted through the logical extension of earlier research on other media forms and the amount of time the average child spends with increasingly sophisticated media.

Effect of the Multimeric Structure of the Factor Vill/von Willebrand Factor Protein on Binding to Platelets

The characteristics of the intact factor VIll/von Willebrand factor protein binding to human platelets was compared to 2-mercaptoethanol-treated factor VIll/von Willebrand factor protein and to fractions of plasma factor VIll/von Willebrand factor protein that elute after the void volume. These studies indicate that the factor VIlI/von Willebrand factor protein larger size oligomers bind prefer...

Factor Vill/von Willebrand Factor Binding to von Willebrand’s Disease Platelets

A form of von Willebrand’s disease has been described with enhanced ristocetin-induced platelet aggregation and anodal migration of the factor VIll/von Willebrand factor protein (type lIb). We studied two families with this form of von Willebrand s disease and macrothrombocytopenia. We have found that these platelets bind more of the normal and intermediate-sized multimers of the factor VIll/vo...

Reliability and Safety of Contra-Lateral Oblique View for Interlaminar Epidural Needle Placement: Standardization of the Appropriate Angle.

In this large retrospective review of a clinical case, Derby et al (1) again show that the contralateral oblique (CLO) view is safe and accurate. Loss of resistance cannot be expected before the ventral interlaminar line (VILL) and the needle may be passed with impunity to just before this line. As the interlaminar line is accessed, the loss of resistance should occur immediately or shortly the...
