Abstract
Little work has examined longitudinal associations between parental reflective functioning (PRF) and mind-mindedness (MM), limiting the understanding of separate or bidirectional trajectories of these related but distinct forms of mentalization. We examined cross-lagged associations between PRF, assessed via interview, and MM, coded from play interactions, over 12 months among 90 parents (86% female; 57% White, 43% Black) of infants (Mage = 10.56 months, SD = 8.20) who were participating in The Michigan Model of Infant Mental Health Home Visiting. Data were collected at study enrollment Time 1 (T1) and at 6-month Time 2 (T2) and 12-month Time 3 (T3) postenrollment. Mind-minded comments were coded as appropriate, reflecting accurate interpretation of mental states or nonattuned, characterizing inaccurate interpretations. PRF and appropriate MM each remained stable over time. PRF at the T1 positively predicted appropriate MM at T2. No other cross-lagged associations between PRF and appropriate MM were significant. Concurrent correlations between appropriate MM and PRF were significant only at T3. Nonattuned MM showed stability from T1 to T2 but nonattuned MM at the T2 did not predict nonattuned MM at T3. Greater PRF at T1 predicted less nonattuned MM at T2. No other cross-lagged associations between PRF and nonattuned MM were significant. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
BACKGROUND Research examining the effectiveness of home visiting programs that reduce child maltreatment or associated risks yield mixed findings; some find positive significant impacts on maltreatment, whereas others find small to no effects. The Michigan Model of Infant Mental Health Home Visiting (IMH-HV) is a manualized, needs-driven, relationship-focused, home-based intervention service that significantly impacts maternal and child outcomes; the effect of this intervention on child maltreatment has not been sufficiently evaluated. OBJECTIVE The current study examined associations between treatment and dosage of IMH-HV and child abuse potential in a longitudinal, randomized controlled trial (RCT). PARTICIPANTS AND SETTING Participants included 66 mother-infant dyads (Mother M age = 31.93 years at baseline; child M age = 11.22 months at baseline) who received up to 1 year of IMH-HV treatment (Mdn = 32 visits) or no IMH-HV treatment during the study period. METHODS Mothers completed a battery of assessments including the Brief Child Abuse Potential Inventory (BCAP) at baseline and at the 12-month follow-up assessment. RESULTS Regression analyses indicated that after controlling for baseline BCAP scores, those who received any IMH-HV treatment had lower 12-month BCAP scores compared to those who received no treatment. Additionally, participation in more visits was associated with lower child abuse potential at 12 months, and a reduced likelihood of scoring in the risk range. CONCLUSION Findings suggest that greater participation in IMH-HV is associated with decreased risk for child maltreatment 1 year after initiating treatment. IMH-HV promotes parent-clinician therapeutic alliance and provides infant-parent psychotherapy which differentiate it from traditional home visiting programs.

Abstract
Early infant-parent interaction sets a critical foundation for young children's well-being, and evidence regarding the protective role of secure early relationships has led to increased interest in effective screening and promotion of early relational health in pediatric primary care and home visiting settings. We report findings from two pilot studies conducted in the United States that describe the reliability and validity of a relational health screening tool, the Early Relational Health Screen (ERHS), implemented in two different contexts: an innovative model of relational health promotion in pediatric primary care (Study 1) and an Infant Mental Health Home Visiting (IMH-HV) model (Study 2). Across both studies, a trained clinician rated the ERHS following real-time observation of interaction (i.e., "in-the-moment" ratings). Reliability was assessed by comparing "in-the-moment" ERHS ratings to subsequent coding of the same interaction from video by an independent evaluator. In addition, Study 2 data permitted evaluation of the validity of "in-the-moment" ERHS ratings. Results from both studies indicated reliability of "in-the-moment" ERHS ratings. In addition, Study 2 clinician "in-the-moment" ratings were associated with maternal depression and ratings of child-parent interaction derived from a separate observational task coded by independent evaluators using a different well-validated research-based measure. Discussion highlights the potential of the ERHS as a screening, promotion, and prevention tool that may be feasibly administered by providers across pediatric primary care and home visiting settings.

Abstract
BackgroundThe present study examined the efficacy of the Michigan Model of Infant Mental Health-Home Visiting (IMH-HV) infant mental health treatment to promote the socioemotional wellbeing of infants and young children. Science illuminates the role of parental “co-regulation” of infant emotion as a pathway to young children’s capacity for self-regulation. The synchrony of parent–infant interaction begins to shape the infant’s own nascent regulatory capacities. Parents with a history of childhood adversity, such as maltreatment or witnessing family violence, and who struggle with symptoms of post-traumatic stress may have greater challenges in co-regulating their infant, thus increasing the risk of their children exhibiting social and emotional problems such as anxiety, aggression, and depression. Early intervention that targets the infant–parent relationship may help buffer the effect of parental risk on child outcomes.MethodsParticipants were 58 mother–infant/toddler dyads enrolled in a longitudinal randomized control trial testing the efficacy of the relationship-based IMH-HV treatment model. Families were eligible based on child age (<24 months at enrollment) and endorsement of at least two of four socio-demographic factors commonly endorsed in community mental health settings: elevated depression symptoms, three or more Adverse Childhood Experiences (ACEs) parenting stress, and/or child behavior or development concerns. This study included dyads whose children were born at the time of study enrollment and completed 12-month post-baseline follow-up visits. Parents reported on their own history of ACEs and current posttraumatic stress disorder (PTSD) symptoms, as well as their toddler’s socioemotional development (e.g., empathy, prosocial skills, aggression, anxiety, prolonged tantrums).ResultsMaternal ACEs predicted more toddler emotional problems through their effect on maternal PTSD symptoms. Parents who received IMH-HV treatment reported more positive toddler socioemotional wellbeing at follow-up relative to the control condition. The most positive socioemotional outcomes were for toddlers of mothers with low to moderate PTSD symptoms who received IMH-HV treatment.ConclusionResults indicate the efficacy of IMH-HV services in promoting more optimal child socioemotional wellbeing even when mothers reported mild to moderate PTSD symptoms. Results also highlight the need to assess parental trauma when infants and young children present with socioemotional difficulties.

Abstract
Background Diet is a modifier of metabolic syndrome which in turn is associated with World Trade Center obstructive airways disease (WTC-OAD). We have designed this study to (1) assess the dietary phenotype (food types, physical activity, and dietary habits) of the Fire Department of New York (FDNY) WTC-Health Program (WTC-HP) cohort and (2) quantify the association of dietary quality and its advanced glycation end product (AGE) content with the development of WTC-OAD. Methods WTC-OAD, defined as developing WTC-Lung Injury (WTC-LI; FEV1 < LLN) and/or airway hyperreactivity (AHR; positive methacholine and/or positive bronchodilator response). Rapid Eating and Activity Assessment for Participants-Short Version (REAP-S) deployed on 3/1/2018 in the WTC-HP annual monitoring assessment. Clinical and REAP-S data of consented subjects was extracted (7/17/2019). Diet quality [low-(15–19), moderate-(20–29), and high-(30–39)] and AGE content per REAP-S questionnaire were assessed for association with WTC-OAD. Regression models adjusted for smoking, hyperglycemia, hypertension, age on 9/11, WTC-exposure, BMI, and job description. Results N = 9508 completed the annual questionnaire, while N = 4015 completed REAP-S and had spirometry. WTC-OAD developed in N = 921, while N = 3094 never developed WTC-OAD. Low- and moderate-dietary quality, eating more (processed meats, fried foods, sugary drinks), fewer (vegetables, whole-grains),and having a diet abundant in AGEs were significantly associated with WTC-OAD. Smoking was not a significant risk factor of WTC-OAD. Conclusions REAP-S was successfully implemented in the FDNY WTC-HP monitoring questionnaire and produced valuable dietary phenotyping. Our observational study has identified low dietary quality and AGE abundant dietary habits as risk factors for pulmonary disease in the context of WTC-exposure. Dietary phenotyping, not only focuses our metabolomic/biomarker profiling but also further informs future dietary interventions that may positively impact particulate matter associated lung disease.

Abstract
This study examined changes in parental reflective functioning (PRF) among mothers enrolled in Infant Mental Health-Home Visiting (IMH-HV) and explored whether parental risk, treatment dosage or therapist experience predicted change in PRF. Participants included 75 mothers and their children who were enrolled in IMH-HV delivered by Community Mental Health therapists. Results indicated significant improvements in PRF from baseline to 12-months. Maternal demographic and psychosocial risk, therapist experience and treatment dosage were not directly associated with changes in PRF. However, Mothers who received more treatment sessions from therapists with six or more years of experience demonstrated the greatest improvements in PRF, while mothers who received more treatment sessions from therapists who had been practicing IMH for less than 15 months showed a decline in PRF. Therapists working with very high-risk families may need specific training and ongoing reflective supervision over a period of years to promote improvement in PRF.

Abstract
Fire Department of New York (FDNY) rescue and recovery workers exposed to World Trade Center (WTC) particulates suffered loss of forced expiratory volume in 1 s (FEV1). Metabolic Syndrome increased the risk of developing WTC-lung injury (WTC-LI). We aim to attenuate the deleterious effects of WTC exposure through a dietary intervention targeting these clinically relevant disease modifiers. We hypothesize that a calorie-restricted Mediterranean dietary intervention will improve metabolic risk, subclinical indicators of cardiopulmonary disease, quality of life, and lung function in firefighters with WTC-LI. To assess our hypothesis, we developed the Food Intake REstriction for Health OUtcome Support and Education (FIREHOUSE), a randomized controlled clinical trial (RCT). Male firefighters with WTC-LI and a BMI > 27 kg/m2 will be included. We will randomize subjects (1:1) to either: (1) Low Calorie Mediterranean (LoCalMed)-an integrative multifactorial, technology-supported approach focused on behavioral modification, nutritional education that will include a self-monitored diet with feedback, physical activity recommendations, and social cognitive theory-based group counseling sessions; or (2) Usual Care. Outcomes include reduction in body mass index (BMI) (primary), improvement in FEV1, fractional exhaled nitric oxide, pulse wave velocity, lipid profiles, targeted metabolic/clinical biomarkers, and quality of life measures (secondary). By implementing a technology-supported LoCalMed diet our FIREHOUSE RCT may help further the treatment of WTC associated pulmonary disease.

Abstract
Psychological intimate partner violence (P-IPV) refers to verbal abuse from one partner to another and abuse of power or control from one partner to another. To date, no studies have examined the longitudinal course of P-IPV exposure among mothers or the effect that witnessing P-IPV can have on their children. Using latent class growth analysis, the current study identified five trajectory groups with the following intercept and growth characteristics: low stable, low-increasing, moderate-decreasing, high-decreasing, and consistently elevated. Membership in the four groups characterized by higher P-IPV exposure was predicted by maternal race and exposure to physical abuse. The children of mothers in the low-increasing and consistently elevated groups had elevated scores on the Internalizing and Externalizing scales of the Childhood Behavior Checklist. These findings remained after controlling for child sex, race, cumulative trauma exposure, and maternal depression.

Abstract
Background: Perinatal illness is alarmingly common and has negative effects on maternal and infant well-being. Depression and posttraumatic stress disorder (PTSD), specifically, are characterised by negative views of the self and others, which may impact a mother's perceptions of herself and her child. Objective: This study examined the relationship between depression and PTSD symptoms, maternal perceptions of infant emotions, and parenting behaviours. Methods: 120 pregnant, mostly low-income women and their infants (after birth) participated in a longitudinal study. Maternal depression and PTSD symptoms were assessed during pregnancy and 1 year postpartum; maternal perceptions of infant emotions and parenting quality were assessed at 1 year. Results: Correlation analyses revealed significant, negative associations between prenatal (but not postnatal) psychiatric symptoms and positive perceptions of infant emotions, as well as between positive perceptions of infant emotions and negative parenting. Results also revealed significant indirect effects of prenatal depressive and PTSD symptoms on negative parenting via perceptions of infant emotion (95% CIs:.0013 -.0200 and.0008 -.0083, respectively). Conclusion: Findings highlight that mothers should be routinely screened for psychiatric symptoms during the perinatal period, and perceptions of infant emotions may be an important target for parent-infant mental health interventions.

Abstract
Background Our group has identified the receptor for advanced glycation end-products (RAGE) as a predictor of World Trade Center particulate matter associated lung injury. The aim of this systematic review is to assess the relationship between RAGE and obstructive airways disease secondary to environmental exposure. Methods A comprehensive search using PubMed and Embase was performed on January 5, 2018 utilising keywords focusing on environmental exposure, obstructive airways disease and RAGE and was registered with PROSPERO (CRD42018093834). We included original human research studies in English, focusing on pulmonary end-points associated with RAGE and environmental exposure. Results A total of 213 studies were identified by the initial search. After removing the duplicates and applying inclusion and exclusion criteria, we screened the titles and abstracts of 61 studies. Finally, 19 full-text articles were included. The exposures discussed in these articles include particulate matter (n=2) and cigarette smoke (n=17). Conclusion RAGE is a mediator of inflammation associated end-organ dysfunction such as obstructive airways disease. Soluble RAGE, a decoy receptor, may have a protective effect in some pulmonary processes. Overall, RAGE is biologically relevant in environmental exposure associated lung disease. Future investigations should focus on further understanding the role and therapeutic potential of RAGE in particulate matter exposure associated lung disease.

Abstract
Despite an aging population and an increase in the prevalence of chronic severe illness, many patients will not have end-of-life care discussions with their outpatient physicians. This very likely contributes to considerable hospital utilization toward the end of life, without any clear benefit. At our medical center, we noticed a very high rate of floor-to-intensive care unit (ICU) transfers for patients with life-limiting illness and poor prognosis. We initiated a quality assessment and improvement project aimed at increasing goals-of-care conversations for high-risk patients early in their hospital stays. Patients were identified using a risk assessment score combined with presence of life-limiting illness and alerting the inpatient attending physician to the patient's severity of illness. Inpatient attending physicians were encouraged to expeditiously initiate and document goals-of-care discussions with their patients and families or to consult palliative care. Patient data were extracted retrospectively from high-risk patients prior to and during the intervention period. Analysis showed a significant increase in overall goals-of-care discussions and a significant reduction in floor-to-ICU transfers during initial admission. There was no change in mortality at 1 year, but there was a trend toward more in-home deaths for those patients who died within the year. Early inpatient goals-of-care conversations may reduce ICU utilization at index hospitalization and may reduce overall health-care utilization near the end of life.

Abstract
Graded support stockings are widely used in the prophylaxis of postoperative deep vein thrombosis (DVT). For many years (following the results of early trials) one brand has dominated the market. We now describe an assessment of an alternative brand. Fifty patients undergoing major abdominal surgery were provided with graduated support stockings postoperatively for the prophylaxis of DVT. Two different makes of stockings were used, one on each leg; the leg randomly determined by an odd or even year of birth. Data was collected from each patient in order to determine patient compliance. Patients experienced no significant difference in comfort between the two makes, although, on balance, product ‘A’ was found to be more comfortable. No pressure sores were caused by either stocking type and there was no clinical evidence of DVT in any of the 50 patients. However, there were two cases of pulmonary embolus. Samples of both stockings were tested in a materials testing laboratory, to determine the pressure gradients which they could be expected to apply in normal use, and the results of these tests suggest that there are major differences in the performance of the products concerned.

Abstract
The T cell composition of the peritoneal cavity (PerC) in naïve BALB/c, C57BL/6, DBA/2J, and B-1 B cell-defective BALB.xid mice was investigated. The BALB.xid PerC T cell pool had a high CD4:CD8 T cell ratio relative to the other strains whose ratios were similar to those found in their lymph node and spleen. All mice had significant representation of T cells with an activated (CD25(+), GITR(hi), CD44(hi), CD45RB(lo), CD62L(lo)) phenotype and low numbers of Foxp3(+) T(reg) cells in their PerC. Despite a phenotype indicative of activation, peritoneal T cell responses to CD3 ligation were very low for C57BL/6 and BALB.xid, but not BALB/c, mice. Enzyme inhibition and cytokine neutralization studies revealed active suppression of the T cell response mediated by the macrophages that represent a significant portion of PerC leucocytes. Driven by IFNγ to express iNOS, macrophages suppressed T cell activation in vitro by arginine catabolism. Although BALB/c T cells were also in a macrophage-dense environment their limited IFNγ production failed to trigger suppression. This difference between BALB/c and BALB.xid PerC T cells suggests a role for xid in shaping macrophage-mediated immune regulation.

Abstract
T-lymphocyte activation triggered by anti-CD3, endogenous or exogenous superantigen, and mitogens was suppressed in a cell-dose-dependent fashion by peritoneal cavity (PerC) leucocytes. Study of lymphocyte-deficient mice and the use of multiparameter fluorescence-activated cell sorter analyses revealed that macrophages were responsible for this form of immune regulation. Interferon-gamma was essential to trigger suppression, which, by enzyme inhibition studies, was shown to be the result of tryptophan and arginine catabolism. These results illustrate that macrophages, which are classically defined by their innate effector function as antigen-presenting cells, have the potential to temper adaptive immunity.

Abstract
The B lymphocyte subsets of X-chromosome-linked immune-deficient (XID) mice were examined by flow cytometric analyses of spleen and peritoneal cells. As shown in prior studies, young adult XID mice had reduced representation of the CD5+ (B-1a) subset in their peritoneal cavity. However, the CD11b+ (B-1b) B-cell subset was present and exhibited the IgM(hi) CD45(lo) CD23- phenotype characteristic of most B-1 cells. Although present at a lower frequency than that found in their normal counterparts, B-1b cells were evident in CBA/N and (XD2J)F1 male mice. With increasing age, B-1b cell number increased and in the oldest XID mice were present as B-cell chronic lymphocytic leukaemia. These results show that XID mice do have B-1 cells, particularly the B-1b subset.

Abstract
Superantigens (SAgs) activate TH cells and induce their differentiation into cytokine-producing effector cells. Supranormal cytokine production is characteristic of SAg-induced polyclonal TH activation. Study of this interaction has focused upon TH cell function to the relative exclusion of other lymphocyte populations. SAgs also impact cells dependent upon TH cells for their differentiation and disrupt the normal homeostasis of the immune system. In this report, several changes in lymphocyte biology that result from SAg activation of TH cells are described. SCID mice, reconstituted with the SAg-expressing cells of DBA/2J mice, were employed as secondary recipients of SAg-reactive TH cells. Significant increases in serum IgM and IgG2a production were noted after the transfer of SAg-reactive It cells. Both B and CD8 T lymphocyte numbers increased with those of CD8 T cells surpassing levels found in normal mice. These results illustrate the ability of the TH-SAg interaction to disrupt B and CD8+ T lymphocyte homeostasis.

Abstract
HYPOTHESIS Closed postoperative peritoneal lavage (CPPL) with chlorhexidine gluconate reduces the number of intraperitoneal bacteria and improves the outcome of intra-abdominal infection. DESIGN Laboratory animal trial. INTERVENTIONS Intra-abdominal infection was produced in mice by the cecal ligation and puncture technique. After 16 to 18 hours, the animals underwent relaparotomy and placement of an intra-abdominal catheter for CPPL. In the first experiment animals were randomly divided into 4 groups: no lavage (served as a control), CPPL with chlorhexidine. CPPL with cefoxitin, and CPPL with lactated Ringer solution (LR). Lavage was continued intermittently every 8 hours for 24 hours. All animals received systemic cefoxitin every 8 hours for 7 days. Mortality was recorded every 8 hours for 10 days. In the second experiment, animals were divided into 3 groups: no lavage (served as a control), CPPL with chlorhexidine, and CPPL with LR. Lavage was continued intermittently every 8 hours for 24 hours. The animals were killed 48 hours after reoperation. Bacterial counts from peritoneal fluid and biopsy specimens, as well as peritoneal white blood cell counts, were measured before and after lavage. RESULTS Closed postoperative peritoncal lavage with chlorhexidine reduced mortality from 71% in a control group to 37% (P = .003). There was no survival benefit in either the CPPL with cefoxitin (91% mortality) (P = .14) or CPPL with LR groups (90% mortality) (P = .17). The statistically significant findings of analysis of variance evaluation demonstrated a decrease in bacterial counts after cecal excision in all 3 groups. There was a greater reduction in bacterial counts in the chlorhexidine group compared with the control group (P<.05). Bacterial counts decreased in peritoneal fluid, as well as in tissue biopsy specimens, after cecal excision. White blood cell counts significantly decreased after cecal excision in all 3 groups. There was no difference in white blood cell counts between the groups. Correlation analyses demonstrated weak interaction between bacterial and white blood cell counts before or after treatment in all the groups. Pearson r ranged from -0.37 to +0.35, none of which were statistically significant. CONCLUSIONS In our experiments chlorhexidine lavage resulted in a 50% reduction in mortality and a significant reduction in bacterial counts compared with the control group. There was no survival benefit from lavage with either cefoxitin or LR. There was no reduction in bacterial counts in the LR group relative to the control group. Thus, the survival benefit and the reduction in bacterial numbers are attributed to the antibacterial properties of chlorhexidine rather than to the mechanical washing of the abdominal cavity. Closed postoperative peritoneal lavage with 0.05% chlorhexidine gluconate might be useful in the multimodal treatment of intra-abdominal infection.

Abstract
Studies of superantigens (SAg) have focused primarily on their impact on CD4+ T cells, largely bypassing the impact of the sequelae of this interaction upon the antigen-presenting cell (APC). Sequelae of SAg-induced CD4+ T-cell activation include the 'bathing' of the SAg-presenting cell with cytokines that promote the differentiation of the APC. In this report, the SAg-induced differentiation of Mls+ DBA/2J B cells was studied in vivo by their transplantation into B-cell-defective BALB.xid recipients. Rapid, high-level serum immunoglobulin M (IgM) production was noted shortly after transfer, disappearing by 3 weeks. Donor B cells, as evidenced after their chemical and genetic impairment and by the use of an IgM allotype-disparate donor-recipient combination, contributed to this transient IgM production. These results clarify a discrepancy in the literature regarding donor B-cell contribution to IgM production and illustrate a model system to utilize SAg to study B-lymphocyte diversity.

Abstract
B-cell heterogeneity studies have historically focused upon BALB/c mice and their derivatives. In contrast, the B cells of DBA/2J mice, a prototype strain for the study of the endogenous minor lymphocyte stimulatory (Mls) viral superantigen Mls-1a, have not been extensively investigated. DBA/2J B cells, by functioning as Mls-1a antigen-presenting cells, influence their own differentiation and diversity by inducing the proliferation and differentiation of specific CD4 T-cell subsets. In this report, the B cells of DBA/2J and BALB/c mice were compared for their ability to restore B-cell function in severe combined immunodeficient (SCID) recipients. Although spleen and bone marrow cells from these strains exhibited similar restoration of serum IgM production, the transfer of DBA/2J B cells into SCID mice led to greater IgG1 production. The peritoneal cells of DBA/2J mice consisted of a lower percentage of B-1 B cells and were less capable of restoring B-cell function after transfer into SCID recipients. These differences are discussed with respect to the possible role of viral superantigens in influencing B-lymphocyte diversity.

Abstract
Historically, University teaching hospitals have been the primary providers of health care to the indigent population. With the advent of managed health-care plans, the university hospitals have seen a rapid decline in their obstetrical patient populations. This decrease is reflected in the numbers of deliveries and gynecological surgeries. From 1990 to 1995, these changes resulted in a significant decline in deliveries at our hospital, the Lyndon B. Johnson General Hospital. To reverse this ominous trend, we instituted a variety of changes resulting in a more patient-centered system and found an improvement in the numbers of obstetrical patients. In the following report, we describe these changes and the subsequent outcome.

Abstract
In vivo studies of lymphocyte biology have used intravenous (i.v.) injection as the primary mode of cell transfer, a protocol consistent with the anatomic distribution of most lymphocytes. However, for study of peritoneal cavity B cells, i.v. injection does not correlate with anatomical localization. This report describes the restoration of B-cell function in B lymphocyte-defective X-chromosome-linked immune-defective (XID) mice after intraperitoneal transfer of immunoglobulin heavy chain (Igh)-disparate peritoneal cavity (PerC) cells. In contrast to i.v. transfer, intraperitoneal (i.p.) transfer restored B-cell function in young, but not adult (> 8 weeks), XID mice. When host and donor Igh allotype matched, PerC B-cell engraftment was noted in older recipients; this reconstitution however, was also age-dependent. Migration from the peritoneum to systemic circulation was necessary for serum IgM production as shown by the presence of donor antibody-secreting cells in the host spleen. Host lymphocytes also influenced the success of i.p. transplantation as severe combined immune-deficient mice, regardless of age, exhibited donor serum IgM production. Recipient age, Igh allotype, and immune-deficiency were found to have an impact on the ability of i.p.-transferred PerC B cells to restore B-cell function in XID mice.

Abstract
The impact of intrinsic B lymphocyte heterogeneity and of microenvironmental influences on serum immunoglobulin production by B cells was examined by intravenous (i.v.) and intraperitoneal (i.p.) transfer of BALB/c and BALB.xid (X-chromosome-linked immunedefective; XID) lymph node (LN), splenic (SP) and peritoneal cavity (PerC) cells into severe-combined immune-defective (SCID) mice. The results indicate that each B-cell source restores all immunoglobulin classes within 5 weeks of transfer, the rates for each isotype, however, differ between the B-cell sources. Serum IgM levels were restored most rapidly by PerC cell transfer, followed by SP and LN cell transfer. In addition, normal immunoglobulin levels were reached in the absence of complete lymphoid reconstitution. Serum immunoglobulin phenotypes characteristic of the donor strain, e.g. reduced IgM and IgG3 production by XID B cells, were maintained after transfer into the SCID recipient. Microenvironmental influences were indicated by reduced immunoglobulin production after i.p. transfer and after i.v. transfer into irradiated SCID recipients. The data show that both B-cell type and microenvironment play significant roles in generating the heterogeneous pool of B cells required for humoral immunity.

Abstract
The primary method employed to correct immune deficiency is bone marrow transfer. Depending upon the exact nature of the immune deficiency, however, alternative cell sources may be used to provide a more rapid reconstitution of immune function. In this report, peritoneal cavity (PerC) B cells are shown to be effective in the rapid emendation of the B-cell defect exhibited by XID mice. Restoration of normal numbers of splenic IgM antibody-secreting cells (ASC) and serum IgM levels were observed 4 and 7 days, respectively, after the i.v. transfer of 3 x 10(6) PerC. This regimen also restored responsiveness to thymus-independent type 2 (TI-2) antigens in XID recipients. Transfer of 30 x 10(6) spleen (SP) cells restored these functions in XID recipients but at a considerably slower rate. The data indicate that introducing a small number of PerC B cells into systemic circulation results in the rapid restoration of serum IgM levels in unirradiated XID mice.

Abstract
College students and community-dwelling older adults were compared on Injustice and Personal Power scales and measures of religiosity. "Personal Power" scores varied significantly as a function of age and gender. These differences were attributable to a significantly lower belief in "Personal Power" for the group of older women. As predicted, "Injustice" scores were significantly higher for women than for men, reflecting a greater belief that conditions can be unjust. No significant difference between older and younger adults on "Injustice" scores was obtained. Significant positive correlations between measures of religiosity and "Injustice" scores were obtained, while religiosity was not significantly correlated with "Personal Power." This pattern of results suggests that there is value in utilizing separate measures of "Injustice" and "Personal Power" scores. Suggestions are made for examining further the complex relationship among demographic variables, belief in a just world, and measures of religiosity.

Abstract
The San Francisco Men's Health Study is a prospective study of the epidemiology and natural history of the acquired immunodeficiency syndrome in a cohort of 1034 single men, 25 to 54 years of age, recruited by multistage probability sampling. At entry, June 1984 through January 1985, the seropositivity rate for human immunodeficiency virus (HIV) infection among homosexual/bisexual study participants was 48.5%. No heterosexual participants were HIV seropositive. Among homosexual/bisexual men reporting no male sexual partners in the two years before entry into the study, seropositivity was 17.6%. For those reporting more than 50 partners, seropositivity was 70.8%. Only receptive anal/genital contact had a significantly elevated risk of HIV infection. Douching was the only ancillary sexual practice that contributed significantly to risk of infection.

Abstract
Human mammary cells were examined for the presence of the high-molecular-weight surface glycoprotein fibronectin. Early passage mammary epithelial cell and fibroblast cultures from both carcinomas and normal tissues were tested for the presence of cell-associated fibronectin by immunofluorescence microscopy and for the synthesis and secretion of fibronectin by specific immunoprecipitation of metabolically labeled protein. In vivo frozen sections of primary carcinomas and normal tissues were tested for the localization of fibronectin by immunofluorescence microscopy. In contrast to the extensive fibrillar networks of fibronectin found in the fibroblast cultures, the epithelial cell cultures from both tissue sources displayed a pattern of cell-associated fibronectin characterized by powdery, punctate staining. However, the cultured epithelial cells, as well as the fibroblasts, secreted large quantities of fibronectin into the medium. Putative myoepithelial cells also displayed extensive fibrillar networks of fibronectin. The difference in cell-associated fibronectin distribution between the epithelial cells and the fibroblasts and putative myoepithelial cells provided a simple means of quantitating stromal and myoepithelial cell contamination of the mammary epithelial cells in culture. In vivo, normal tissues showed fibronectin primarily localized in the basement membrane surrounding the epithelial cells and in the stroma. Most primary carcinomas displayed powdery, punctate staining on the epithelial cells in addition to the fibronectin present in the surrounding stroma.

Abstract
We have described a cell line, UC1-B, derived spontaneously from BALB/3T3 mouse embryo cells, which, unlike the standard BALB/3T3, are morphologically transformed and produce bizarre viral forms in response to murine leukemia virus. Although UC1-B and BALB/3T3 are morphologically similar, and both form contact-inhibited monolayers at confluence, the UC1-B cells are partially transformed because: they grow to a slightly higher saturation density than 3T3 cells, they grow in medium lacking serum growth factors, and they produce tumors in mice. Another clone, 12A-3, derived from BALB/3T3, also transforms and produces bizarre viral forms after infection with murine leukemia virus. Unlike UC1-B cells, the 12A3-8 cells are identical in growth properties to BALB/3T3; therefore, a partially altered morphology is not required for the induction of transformation by murine leukemia virus.
