TL;DR: The role of catalase in antioxidant defense is dependent on the type of tissue and the model of oxidant-mediated tissue injury, and studies showed that cortical injury from physical impact caused a significant decrease in NAD-linked electron transfer activities and energy coupling capacities in brain mitochondria of Cat knockout mice but not wild-type mice.

TL;DR: This polyacrylamide gel electrophoresis-based method can provide a reliable assessment of the type of gelatinase, relative amount, and activation status (latent, compared with active enzyme forms) in cultured cells, tissues, and biological fluids.
Abstract: Gelatin zymography is a simple yet powerful method to detect proteolytic enzymes capable of degrading gelatin from various biological sources. It is particularly useful for the assessment of two key members of the matrix metalloproteinase family, MMP-2 (gelatinase A) and MMP-9 (gelatinase B), due to their potent gelatin-degrading activity. This polyacrylamide gel electrophoresis-based method can provide a reliable assessment of the type of gelatinase, relative amount, and activation status (latent, compared with active enzyme forms) in cultured cells, tissues, and biological fluids. The method can be used to investigate factors that regulate gelatinase expression and modulate zymogen activation in experimental systems. The system provides information on the pattern of gelatinase expression and activation in human cancer tissues and how this relates to cancer progression. Interpretation of the data obtained in gelatin zymography requires a thorough understanding of the principles and pitfalls of the technique; this is particularly important when evaluating enzyme levels and the presence of active gelatinase species. If properly used, gelatin zymography is an excellent tool for the study of gelatinases in biological systems.

TL;DR: In this article, the authors investigated whether or not teacher stress, negative affect, and self-efficacy predict the quality of student-teacher relationships and found that negative teacher-student relationships were predicted by teacher stress.
Abstract: Students' misbehavior has been consistently linked to teachers' reports of stress. The purpose of this study was to investigate whether or not teacher stress, negative affect, and self-efficacy predict the quality of student–teacher relationships. Participants included 113 elementary (K-5th) teachers in a metropolitan area in the United States. A survey method was used to measure teacher perceptions in working with difficult students and their relationships with students. Negative teacher–student relationships were predicted by teacher stress. Significant correlations were found among negative affect, teacher stress and negative relationships. Implications for teacher support and continuing education issues are discussed.

TL;DR: The Type I and II error properties of the t test were evaluated by means of a Monte Carlo study that sampled 8 real distribution shapes identified by Micceri (1986, 1989) as being representative of types encountered in psychology and education research.

TL;DR: It is suggested that once-daily administration of aminoglycosides has a predictably lower probability of causing nephrotoxicity than twice- daily administration.
Abstract: The nephrotoxicity and ototoxicity associated with once-daily versus twice-daily administration of aminoglycosides was assessed in patients with suspected or proven gram-negative bacterial infections in a randomized, double-blind clinical trial. Patients who received therapy for ≥72 h were evaluated for toxicity. Patients also received concomitant antibiotics as deemed necessary for treatment of their infection. Plasma aminoglycoside concentrations, prospective aminoglycoside dosage adjustment, and serial audiologic and renal status evaluations were performed. The probability of occurrence of a nephrotoxic event and its relationship to doses and daily aminoglycoside exposure served as the main outcome measurement. One hundred twenty-three patients were enrolled in the study, with 83 patients receiving therapy for at least 72 h. For 74 patients plasma aminoglycoside concentrations were available for analysis, and the patients formed the group evaluable for toxicity. The primary infectious diagnosis for the patients who were enrolled in the study were bacteremia or sepsis, respiratory infections, skin and soft tissue infections, or urosepsis or pyelonephritis. Of the 74 patients evaluable for toxicity, 39 received doses twice daily and 35 received doses once daily and a placebo 12 h later. Nephrotoxicity occurred in 6 of 39 (15.4%) patients who received aminoglycosides twice daily and 0 of 35 patients who received aminoglycosides once daily. The schedule of aminoglycoside administration, concomitant use of vancomycin, and daily area under the plasma concentration-time curve (AUC) for the aminoglycosides were found to be significant predictors of nephrotoxicity by multivariate logistic regression analysis (P ≤ 0.001). The time to a nephrotoxic event was significantly influenced by vancomycin use and the schedule of administration, as assessed by Cox proportional hazards modeling (P ≤ 0.002). The results of the multivariate logistic regression analysis and the Cox proportional hazards modeling demonstrate that both the probability of occurrence and the time to occurrence of aminoglycoside nephrotoxicity are influenced by the schedule on which the aminoglycoside is administered as well as by the concomitant use of vancomycin. Furthermore, this risk of occurrence is modulated by the daily AUC for aminoglycoside exposure. These data suggest that once-daily administration of aminoglycosides has a predictably lower probability of causing nephrotoxicity than twice-daily administration.
