Type Ⅰ,Ⅲ and Ⅴ collagens were extracted from bovine dermis and cornea by using pepsin treatment in acetic acid solution,followed by salt precipitation and dialysis,to purify and isolate each type of collagens.The preparation process was analyzed by using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE).A reducing agent,2-mercaptoethanol,was used to remove disulfide bonds and analyze the structure of the bonds involved between α chains in some types of collagens.The use of delayed reducing methods resulted in the difference between α1(Ⅲ) and α1(Ⅰ) chains in a mixture containing type Ⅰ and Ⅲ collagens.The structure of disulfide bonds among α chains exists potentially in type Ⅴ collagen prepared from the pepsin-treatment extraction at 4℃,which differs from type Ⅲ collagen in relation to the locations of disulfide bonds.Compared with pepsin-treated collagen at 4℃,the relative molecular weights of α1(Ⅴ) and α2(Ⅴ) chains treated at room temperature decrease by 4.6% and 6.0%,respectively.It is concluded that type Ⅰ,Ⅲ and Ⅴ collagens can be prepared from bovine dermis and cornea by the use of pepsin treatment,salt precipitation and dialysis.The interchain disulfide bonds lie potentially near the edges of termini of type Ⅴ collagen molecules in extracellular matrix,and a small number of interchain crosslinks exist in type Ⅴ collagen.  相似文献

Due to the increased demands for science and technology (S&T) in criminal justice (CJ) occupational preparation and in response to the growing interest of students in forensics, this study explores the attitudes of CJ majors towards S&T. Despite the acknowledgment that S&T skills are helpful in gaining employment, CJ majors reported less favorable attitudes than S&T majors, reporting: less interest in gaining S&T knowledge, fewer social benefits of S&T, and greater concerns that S&T are dangerous to society than traditional forensic science majors. While these findings raise some fundamental questions about the suitability of increased representation of S&T courses within CJ curriculum, authors argue that CJ curricular goals must continue to evolve to foster innovative students who are academically prepared to meet the twenty-first century challenges of their future careers.  相似文献

Objective

Children of mothers with mental illness are at risk for multiple untoward outcomes, including child maltreatment and foster care placement. The purpose of this analysis was to determine the association between maternal mental illness and children's long term safety and stability.

Methods

A multi-sector administrative dataset from the Department of Social Services (DSS) and Department of Mental Health (DMH) was analyzed. The sample was 4,895 low income families (mother and child dyads) first reported to child welfare in 1993 or 1994. Families were followed until March of 2009. Dates of new report and foster care placement were obtained from DSS data. ICD-09 or ICD-10 diagnostic codes were obtained from Department of Mental Health data. Schizophrenic disorders, episodic mood disorders, anxiety disorders and personality disorders were examined.

Results

New reports were more likely for children of mothers with mental illness, regardless of diagnosis. While overall 67% of children had a new report over the course of their childhood, rates ranged from 80 to 90% for children of mothers with mental illness and occurred within a shorter time frame than for other children. In the multivariate models, mood (HR = 1.41, p < .001) and anxiety disorders (HR = 1.32, p < .05) placed children at greater risk for new reports. The proportion of children with foster placements was more than double for children of mothers with mental illness than for other children. In the multivariate model, anxiety disorders were strongly associated with the risk of placement (HR = 1.75, p < .001).

Conclusions and Practice implications

Important differences in safety and stability were found between children of mothers with and without mental illnesses, as well as some variability across diagnoses. Since these mothers had already received services our findings suggest that access is not enough. The services they are receiving or have received may be an ineffective approach to helping them parent safely.  相似文献
