Decrease in N-Acetylaspartate Following Concussion May Be Coupled to Decrease in Creatine

Decrease in N-acetylaspartate following concussion may be coupled to decrease in creatine.

OBJECTIVES To assess the time course changes in N-acetylaspartate (NAA) and creatine (Cr) levels in the brain of athletes who suffered a sport-related concussion. PARTICIPANTS Eleven nonconsecutive athletes with concussive head injury and 11 sex- and age-matched control volunteers MAIN OUTCOME MEASURES : At 3, 15, 30, and 45 days postinjury, athletes were examined by proton magnetic resonan...

MODIFIED RADICAL MASTOIDECTOMY: TECHNIQUES TO DECREASE FAILURE

The aims of surgical treatment for cholesteatoma include complete removal of disease and formation of a dry, self cleaning ear in addition to hearing reconstruction. This presentation concentrates on techniques of open mastoid surgery or modified radical mastoidectomy to achieve a well-constructed cavity. This study analyzes both primary and revision mastoid surgery referred to the author. ...

Transient decrease in F-actin may be necessary for translocation of proteins into dendritic spines.

It remains poorly understood as to how newly synthesized proteins that are required to act at specific synapses are translocated into only selected subsets of potentiated dendritic spines. Here, we report that F-actin, a major component of the skeletal structure of dendritic spines, may contribute to the regulation of synaptic specificity of protein translocation. We found that the stabilizatio...

Decrease in creatine kinase in human prostatic carcinoma compared to benign prostatic hyperplasia.

Many previous studies have shown that a proportion of patients with carcinoma of the prostate have increased activity of the creatine kinase (E.C. 2.7.3.2) isoenzyme designated BB in sera from their peripheral blood. We have analyzed tissues from prostatic hyperplasia of 22 patients and from prostatic carcinoma of 23 additional patients. Prostatic carcinomas contain less (p less than 0.001) cre...
