National Department of Defense surveillance data for antibiotic resistance and emm gene types of clinical group A streptococcal isolates from eight basic training military sites 下载免费PDF全文
Barrozo CP Russell KL Smith TC Hawksworth AW Ryan MA Gray GC 《Journal of clinical microbiology》2003,41(10):4808-4811
Antibiotic resistance and emm gene types were examined from 692 Group A streptococci isolates from eight United States military basic training sites between 1998 and 2001. Macrolide resistance was associated with geographic sites and emm type. These data are useful for vaccine development initiatives and antimicrobial treatment considerations. 相似文献

Exercise motivation and adherence in cancer survivors after participation in a randomized controlled trial: An attribution theory perspective 总被引:1,自引:0,他引:1
Courneya KS Friedenreich CM Sela RA Quinney HA Rhodes RE Jones LW 《International journal of behavioral medicine》2004,11(1):8-17
The purpose of this study was to examine postprogram exercise motivation and adherence in cancer survivors who participated
in the Group Psychotherapy and Home-Based Physical Exercise (GROUP-HOPE; Courneya, Friedenreich, Sela, Quinney, & Rhodes,
2002) trial. At the completion of the GROUP-HOPE trial, 46 of 51 (90%) participants in the exercise group completed measures
of attribution theory constructs. A5-week follow-up self-report of exercise wasthen completed by 30 (65%) participants. Correlational
analyses indicated that program exercise, perceived success, expected success, and affective reactions were strong predictors
of postprogram exercise. In multivariate stepwise regression analyses, program exercise and perceived successwere the strongest
predictors of postprogram exercise. Additionally, perceived success was more important than objective success in understanding
the attribution process, and it interacted with personal control to influence expected success and negative affect. Finally,
postprogram quality of life and changes in physical fitness were correlates of perceived success. We concluded that attribution
theory may have utility for understanding postprogram exercise motivation and adherence in cancer survivors. 相似文献

To determine the influence of the vitamin D receptor (VDR) gene FokI and BsmI genotype on bone mineral density response to two exercise training modalities, 206 healthy men and women (50-81 years old) were studied before and after approximately 5-6 months of either aerobic exercise training (AT) or strength training (ST). A totla of 123 subjects completed AT (51 men, 72 women) and 83 subjects completed ST (40 men, 43 women). DNA was extracted from blood samples of all subjects and genotyping was performed at the VDR FokI and BsmI locus to determine its association to training response. Total body, greater trochanter and femoral neck bone mineral density (BMD) were measured before and after both training programmes using dual-energy X-ray absorptiometry. VDR BsmI genotype was not significantly related to BMD at baseline or after ST or AT. However, VDR FokI genotype was significantly related to ST- but not AT-induced changes in femoral neck BMD (P < 0.05). The heterozygotes (Ff) in the ST group approached a significantly greater increase in femoral neck BMD (P = 0.058) compared to f homozygotes. There were no significant genotype relationships in the AT group. These data indicate that VDR FokI genotype may influence femoral neck BMD response to ST, but not AT. 相似文献

Factor analysis of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in a brain-damaged sample 总被引:1,自引:0,他引:1
The Wechsler Adult Intelligence Scale-Revised (WAIS-R) was factor analyzed for a sample of 100 diagnostically heterogeneous brain-damaged patients. Subjects were from two VA Medical Centers located in the Midwest with means for age, education, and Full Scale IQ of 52.31 (SD = 14.41), 11.37 (SD = 2.57), and 86.72 (SD = 10.78), respectively. A principal factor analysis followed by Varimax rotation provided evidence for the existence of three factors underlying the WAIS-R (i.e., Performance, Verbal, and Freedom from Distractibility). The present results are consistent with earlier studies that employed the 1939 and 1955 versions of Wechsler's Adult Intelligence Scale with neurologically impaired subjects. 相似文献

Highly purified preparations of mouse gangliosides have been demonstrated to bind to purified preparations of lipopolysaccharide (LPS). In some instances, the binding has been demonstrated to be dependent upon the presence of sialic acid in the ganglioside preparation. The binding of gangliosides to LPS from the deep rough Salmonella minnesota Re mutant has suggested that the interaction involves the lipid A-2-keto-3-deoxyoctulosanate region of the LPS macromolecule. The interaction between gangliosides and LPS has been demonstrated to result in an abrogation of lipid A dependent activation of the classical pathway of serum complement by Re LPS. Surprisingly, however, the presence of sialic acid containing glycolipids has been shown to enhance significantly the capacity of LPS to initiate activation of the alternative pathway of complement. These data suggest that sialic acid can enhance as well as inhibit the formation of a stable alternative-pathway C3 convertase. 相似文献

Psychological and neuropsychological aspects of COPD 总被引:2,自引:0,他引:2
A review of the literature dealing with the effects of chronic obstructive pulmonary disease (COPD) on psychological and neuropsychological functioning indicates that significant emotional and adaptive deficits characterize this patient population. Psychiatric consultation can provide valuable assistance to the primary care physician by reducing emotional distress and correcting dysfunctional attitudes and beliefs. Neuropsychological assessment can elucidate an individual's neurobehavioral resources and deficits. 相似文献

For the WAIS-R old age standardization sample, unusual Verbal-Performance IQ combinations were generated at the .05 and .01 levels of significance. In a preliminary attempt to determine the neurological significance of these unusual test score combinations, the standardization based values were compared to those of a small sample of elderly brain-injured subjects. The frequency of unusual IQ combinations was essentially the same for the normal and brain-damaged elderly. Unusual VIQ-PIQ combinations should not be considered pathognomonic of neurological impairment. 相似文献

An RNA-binding motif (RBM) gene family has been identified on the human Y
chromosome that maps to the same deletion interval as the 'azoospermia
factor' (AZF). We have identified the homologous gene family (Rbm) on the
mouse Y with a view to investigating the proposal that this gene family
plays a role in spermatogenesis. At least 25 and probably >50 copies of
Rbm are present on the mouse Y chromosome short arm located between Sry and
the centromere. As in the human, a role in spermatogenesis is indicated by
a germ cell-specific pattern of expression in the testis, but there are
distinct differences in the pattern of expression between the two species.
Mice carrying the deletion Yd1, that maps to the proximal Y short arm, are
female due to a position effect resulting in non-expression of Sry ;
sex-reversing such mice with an Sry transgene produces males with a high
incidence of abnormal sperm, making this the third deletion interval on the
mouse Y that affects some aspect of spermatogenesis. Most of the copies of
Rbm map to this deletion interval, and the Yd1males have markedly reduced
Rbm expression, suggesting that RBM deficiency may be responsible for, or
contribute to, the abnormal sperm development. In man, deletion of the
functional copies of RBM is associated with meiotic arrest rather than
sperm anomalies; however, the different effects of deletion are consistent
with the differences in expression between the two species.
