Abstract
INTRODUCTION Blood and blood products are essential medical treatments for all age groups. The primary source for blood products in the U.S. is volunteer donors. Thus, donor recruitment and donor retention are vital factors for a blood bank to maintain its supply. We proposed that developing a better understanding of donors' motivations to donate would improve a blood bank's ability to secure a more robust supply of blood. METHODS Individuals ages 18-36 were approached to participate in the study during their blood donation appointment by completing a questionnaire. SAS software was used to statistically analyze the responses. Univariate analysis was done using Fisher's exact test. A multivariate model was constructed controlling for age and marital status, including the variables that were significant in univariate analysis. RESULTS No individual motivating or inhibiting factor reached statistical significance. The odds ratio for subsequent donation for donors with 10-plus donations versus those with one to three donations was 4.296 (p-value 0.004). The odds ratio regarding donors' likelihood of returning to donate for those donating within three to six months versus 1-plus year was 4.806 (p-value < 0.001). No employer was found to discourage blood donations. CONCLUSIONS Although no individual factors were found to be statistically significant, the identification of optimal time intervals and total number of donations at which donors are more likely to return may allow for more strategic scheduling of blood drives, increasing the likelihood of a donor returning while also increasing the total number of donations for that individual.

Abstract
OBJECTIVE To evaluate the safety and efficacy of ocrelizumab plus methotrexate (MTX) or leflunomide (LEF) in patients with active rheumatoid arthritis (RA) and an inadequate response to tumor necrosis factor α inhibitors. METHODS This was a multicenter randomized, double-blind, placebo-controlled, parallel-group study that continued over 48 weeks. Patients receiving stable doses of MTX or LEF were randomized to receive 2 infusions of placebo (n = 277), ocrelizumab 200 mg (n = 278), or ocrelizumab 500 mg (n = 285) on days 1 and 15 as well as at weeks 24 and 26. Coprimary end points were the proportion of patients with response according to the American College of Rheumatology 20% improvement criteria (ACR20) at weeks 24 and 48. Secondary end points included the change from baseline in the modified Sharp/van der Heijde score (SHS) and the ACR50/70 responses. RESULTS ACR20 responses were 22.0% in the placebo group, 42.2% in the ocrelizumab 200 mg group, and 47.9% in the ocrelizumab 500 mg group at 24 weeks and 19.5%, 48.7%, and 50.7%, respectively, at 48 weeks (P < 0.0001 versus placebo for each comparison at each time point). At 48 weeks, patients receiving both doses of ocrelizumab showed significantly improved ACR50 and ACR70 responses of ~3-fold versus placebo. Only those in the ocrelizumab 500 mg group showed statistically significant (P = 0.0017) inhibition of joint damage progression (mean change in the SHS) relative to placebo (61% inhibition) at 48 weeks. Overall adverse events and infections during the 48 weeks of study were comparable in all treatment groups. Serious infections were observed more frequently in patients taking ocrelizumab (5.1% and 4.3%) than in those taking placebo (2.5%). CONCLUSION Patients in both of the ocrelizumab groups met the clinical primary efficacy end points. Inhibition of change in the SHS was statistically significant at 48 weeks for those in the ocrelizumab 500 mg group. The rate of serious infections in this trial was higher for both ocrelizumab doses as compared with placebo.

Abstract
Viral vectors have the potential to provide a fast and economic alternative to transgenic methods for manipulating gene expression in studies of immune system development and function. Although protocols exist for the infection of hematopoietic precursors and peripheral T cells in vitro, critical stages of T cell differentiation are strictly dependent upon a three-dimensional thymic architecture and their analysis poses unique technical challenges. Whole fetal thymic lobes have been used as targets for retroviral and adenoviral infection, both in situ and in vitro, but this approach does not allow for discrimination between lymphoid and stromal components. Isolated thymocytes have been infected by co-culture with viral producer cells, but under these conditions they rapidly lose their developmental potential. To overcome these problems we have combined a number of efficient techniques for retroviral production, concentration, and infection that allow us to rapidly achieve significant transduction rates of purified populations of double-negative (DN) and double-positive (DP) thymocytes, single-positive (SP) T lymphocytes, as well as fetal thymic MHC II(+) epithelial cells without the need for co-culture with viral producer cells. Reaggregate thymic organ culture (RTOC) techniques were used to assess the development and function of transduced cells in defined cellular environments. As a demonstration of the utility of these methods, CD80 (B7.1) was transduced into thymic epithelial cells and shown to allow them to mediate negative selection of DP thymocytes, and to act as antigen-presenting cells (APC) to mature T cells. The ability to genetically manipulate primary cells of a specified type and differentiation stage provides a powerful complement to RTOC techniques for the study of T cell development.

Abstract
As recipients of tissue and medical specimens, pathologists and other medical specialists regard themselves as stewards of patient tissues and consider it their duty to protect the best interests of both the individual patient and the public. The stewardship of slides, blocks, and other materials includes providing, under appropriate circumstances, patient materials for research, education, and quality control. The decision to provide human tissue for such purposes should be based on the specific (ie, direct patient care) and general (ie, furthering medical knowledge) interests of the patient and of society. The same standards of responsibility should apply to all medical professionals who receive and use specimens. This document proposes specific recommendations whereby both interests can be fostered safely, ethically, and reasonably.

Abstract
Variant thymoma lines have been described which exhibit a substantially increased level of HLA class I induction by IFN-alpha, but not by IFN-gamma, and an unchanged response of other IFN-alpha-stimulated genes (Burrone et al., EMBO J. 1985. 4: 2855-2860). We report that their amplified response correlates with the nuclear translocation of Rel transcription factors upon prolonged treatment with IFN-alpha. The variant cells contain an IkappaBalpha subset with a significantly shortened half-life, and a constitutively active form of IkappaBalpha efficiently blocks HLA class I induction. Therefore, in addition to STAT-mediated induction, prolonged exposure to IFN-alpha can affect transcription involving Rel factors, which are implicated in the regulation of numerous immune response and viral genes.

Abstract
Transformed fibroblasts exhibit reduced adhesion to substrata, a characteristic attributable in part to reduced expression/increased degradation of extracellular matrix (EM) proteins such as type I collagen. To directly assess the role of EM proteins in cellular transformation, a vKRas-transformed mouse fibroblast cell line was transfected with an alpha 2(I) collagen expression construct. Stable transfectants displaying a partial restoration of type I collagen expression showed a flatter morphology with increased adherence to the substratum. These clones also exhibited a reduced ability to clone in soft agar, slower growth kinetics, and suppression of tumorigenicity in nude mice. Restoration of type I collagen is correlated with down-regulation of ras oncogene-responsive NVL3 VL30 gene expression. These results suggest that in addition to suppressing tumorigenicity by promoting cellular adhesion and cytoskeletal organization, EM proteins such as type I collagen may also act to subvert oncoprotein signaling pathways associated with the malignant phenotype.

Abstract
To investigate the biological functions of the helix-loop-helix Id3 protein, we have examined the effects of ectopic modulation of Id3 expression on in vitro induced differentiation of mouse C2C12 myoblast cells. Transient and stable C2C12 transfectants expressing either inducible or constitutive levels of exogenous Id3 were impaired in their ability to differentiate in response to removal of mitogenic serum growth factors. Stable Id3 transfectants displayed an enhanced proliferative capacity associated with a delay in exit from the cell cycle in response to differentiation induction. Antisense blockade of Id3 potentiated differentiation and exit from S phase of the cell cycle. These observations suggest that Id3 functions as a negative regulator of differentiation by integrating mitogenic growth factor signaling into the gene regulatory program maintaining cell cycle progression.

Abstract
Catatonic patients are often not able to communicate their subjective experiences behind their "fassade of immobility." Therefore was retrospectively (3 weeks later) investigated subjective experiences in 24 catatonic patients with a self-assessment-scale especially for catatonia developed by us. Our results showed that catatonic patients subjectively experience less their altered movements but rather cognitive, i.e. ambivalence, or affective, i.e. intense emotions which couldn't be controlled, alterations. According to our results we were able to distinguish an emotive (intense anxiety) from a non-emotive, i.e. cognitive (predominating ambivalence), subtype in catatonia with regard to subjective experience.

Abstract
Quality assurance indicators in anatomic pathology focus on both technical and cognitive processes that result in a written report. The written report serves as both an intermediate outcome, which, in part, determines patient care outcomes, and a source of information for quality assurance studies. General requirements of a program include procedures that meet Joint Commission on Accreditation of Healthcare Organizations requirements for data gathering, data analysis, action, and effectiveness evaluation; documentation; and personnel standards. Specific indicators in surgical pathology and cytopathology focus on timeliness of reports, diagnostic accuracy, relevance of information in reports to the care of the patient, and proficiency testing. Cytopathology requires some unique indicators because of its dual screening and diagnostic role, including detection of false-negative results and comparison of cytotechnologist and cytopathologist diagnoses. Quality assurance indicators for the autopsy include those for the autopsy pathology as a subdiscipline of pathology as well as those that integrate autopsy information into a program of clinical quality assurance.

Abstract
A prospective study was designed to evaluate the outcome of patients with localized resectable neuroblastoma without regional lymph node involvement when no therapy beyond surgical resection was administered. One hundred one patients observed for 3 to 60 months had a 2-year disease-free survival of 89% (SE = 5%). Of the nine patients experiencing relapse, only three have died. There were no apparent distinguishing characteristics of the nine failures. Due to the favorable prognosis of the subset of neuroblastoma patients, prognostic factor analysis had very limited power and lacked clinical importance. Complete gross removal of the localized tumors is adequate therapy to ensure the survival of the majority of these patients.
