All in the family: atypical Hsp70 chaperones are conserved modulators of Hsp70 activity.

Divergent relatives of the Hsp70 protein chaperone such as the Hsp110 and Grp170 families have been recognized for some time, yet their biochemical roles remained elusive. Recent work has revealed that these "atypical" Hsp70s exist in stable complexes with classic Hsp70s where they exert a powerful nucleotide-exchange activity that synergizes with Hsp40/DnaJ-type cochaperones to dramatically accelerate Hsp70 nucleotide cycling. This represents a novel evolutionary transition from an independent protein-folding chaperone to what appears to be a dedicated cochaperone. Contributions of the atypical Hsp70s to established cellular roles for Hsp70 now must be deciphered.

Parenting Pioneers and Parenting Teams: Strengthening Extended Family Ties in Family Support

Starting with the premise that extended family members often have great influence on family functioning, this article describes social work practice techniques for helping families utilize resources available in the extended family network. Two key concepts are presented: "parenting pioneers," who, while attempting newly learned parenting skills, may struggle with resistance from extended family members; and "parenting teams," in which the focal family is giving to or receiving from extended family members substantial family support. The article presents these practice techniques in the context of family support services, which are characterized as voluntary, preventive, developmental, and based in the concept of empowerment and the ecological perspective.

The Family Preservation Philosophy and Therapy With Lesbian Clients

Family preservation is generally viewed in terms of a rather narrow practice definition. However, it's underlying philosophy offers a strong framework for building a positive, nonbiased helping alliance with lesbian clients in a therapeutic setting. The family preservation philosophy offers a unique heuristic for helping professionals to work with lesbians. Family preservation values teach that the therapist must start with the client's reality, recognize the particular needs of that client, and use the client's strengths in treatment. Also inherent in this perspective is respect and sensitivity to the lesbian client's "cultural context, experience, and history" (Family Preservation Institute, 1995). In other words, in the family preservation philosophy there is no assumption of heterosexuality in the therapeutic relationship; rather there is an assumption of unconditional positive regard. Further, clients are engaged in a dialogue and encouraged to name the challenges they encounter in their own words, from their own perspective. All of these principles will help empower lesbian clients. Lesbians may avoid traditional mental health services in times of need, preferring to depend on alternative services or friendship support networks. The choice not to seek help through mainstream agencies may be based on previous negative experience or on an assumption of the homophobic attitudes which are often inherent in such services. Traditional services are usually based on the medical model. Services based on the family preservation philosophy, however, have the capability of creating therapeutic relationships in which there is no assumption of heterosexuality, where the lesbian client is respected and viewed as a whole, healthy individual.

Toward the Development of Ethical Guidelines for Family Preservation

Family preservation workers need a standard set of ethical guidelines to assist them in providing their service in a proper manner. This paper describes how ethical codes have been developed for the "traditional" mental health care disciplines and why such codes are not sufficient for the type of work done in family preservation. The paper further provides examples of the types of ethical dilemmas family preservation workers encounter as well as suggestions for workers, supervisors, and agencies in dealing with such dilemmas.

Evaluating Family Preservation in Nevada: A University-State Agency Collaboration

In this paper, concepts from the emerging family-centered paradigm in child welfare and mental health are applied to evaluative research in family preservation: the ecological perspective, enhancement of competence, a consumer orientation, and collaborative relationships. The experience of family preservation research collaborators from the School of Social Work at the University of Nevada, Reno and the Nevada Division of Child and Family Services illustrate these concepts. The researchers apply the theory of isomorphism to the research endeavor to produce eight principles of effective research partnerships derived from family-centered concepts and their own experiences.

Editorial: The Demands of Protection, Preservation,and Permanency: Where Has Family Preservation Gone?

This Journal issue provides three important articles that will aid us in explaining what we do in service to families. We are very pleased to have the opportunity to print a major address delivered by William Meezan on "Translating Rhetoric to Reality: The Future of Family and Children's Services." The challenges of serving families under an evolution of models in Kansas is presented in "Family Preservation Services Under Managed Care: Current Practices and Future Directions" by Melanie Pheatt, Becky Douglas, Lori Wilson, Jody Brook, and Marianne Berry. What people doing the work think is addressed by the piece titled, "Perceptions of Family Preservation Practitioners: A Preliminary Study" by Judith Hilbert, Alvin L. Sallee, and James K. Ott. Finally, this issue presents a number of very interesting reviews of new resources.

Translating Rhetoric to Reality: The Future of Family and Children's Services

These remarks were first prepared by the author for the inauguration of the Marion Elizabeth Blue Endowed Professorship in Children and Families at the University of Michigan School of Social Work. They were delivered on October 5, 1999, and originally appeared as a monograph published by the University of Michigan School of Social Work in December 1999. They are reprinted here by permission.

What is Family Preservation and Why Does it Matter?

This paper describes competing ideas about family preservation, defined both as a defined program of social services and a philosophical approach to helping troubled families. A straightforward definition has become almost impossible because the phrase has taken on so many different meanings, provoking controversy about its "real" meaning and value. Indeed, "family preservation" has become the proverbial elephant whose splendors and horrors are described with great certainty by those impressed by only one of its aspects. While skirmishes between "child savers" and "family preservers" have been part of the child welfare field since its beginning at the turn of the last century, recent debates over family preservation have been especially heated, generating more confusion and animosity than might be expected from the ranks of the small and usually mild-mannered social work profession. The debate is so heated that the director of one of the nation's largest child welfare agencies said recently that he is afraid to "even use the two words on the same page." <1> While the debate about the value of family preservation is unresolved, experimentation with different approaches to service delivery over the last two decades has helped to lay the groundwork for a resurgence of interest in family and community-centered reforms. Better understanding of the family preservation "debates" may be helpful if these reforms are to be successful over the long term. The paper discusses the competing ideas, values, and perceptions that have led observers to their different understandings of family preservation. It briefly chronicles the history of child welfare and examines key theories that have helped lay the groundwork for the resurgence of interest in family-centered services. It concludes with observations about how the competing values at stake in family preservation may affect the next generation of reforms.

Individual, Family, and Neighborhood Characteristics and Children's Food Insecurity

A growing body of work documents the influence of neighborhood environments on child health and well-being. Food insecurity is likely linked to neighborhood characteristics via mechanisms of social disadvantage, including access to and availability of healthy foods and the social cohesion of neighbors. In this paper, we utilize restricted, geo-coded data from the Early Childhood Longitudinal Study, which allows us to link individual children with their neighborhood's census characteristics, to assess how the neighborhoods of food secure and food insecure children differ at both the kindergarten level and in third grade. The average food insecure child lives in a neighborhood with a higher proportion of black and Hispanic residents, a higher proportion of residents living in poverty, and a higher proportion of foreign-born and linguistically isolated residents. After accounting for individual and household-level characteristics, children living in neighborhoods with a high proportion of Hispanic and foreign-born residents have a significantly increased risk of food insecurity compared to children living in neighborhoods which are predominantly white and have high socioeconomic status. We argue that interventions which take neighborhood context into account may be most efficacious for curbing child food insecurity.

Citric acid cycle flux and pressure-volume work in the isolated working rat heart

It has been demonstrated previously that the mammalian heart cannot sustain physiologic levels of pressure-volume work if ketone bodies are the only substrates for respiration. In order to determine the metabolic derangement responsible for contractile failure in hearts utilizing ketone bodies, rat hearts were prefused at a near-physiologic workload in a working heart apparatus with acetoacetate and competing or alternate substrates including glucose, lactate, pyruvate, propionate, leucine, isoleucine, valine and acetate. While the pressure-volume work for hearts utilizing glucose was stable for 60 minutes of perfusion, performance fell by 30 minutes for hearts oxidizing acetoacetate as the sole substrate. The tissue content of 2-oxoglutarate and its transamination product, glutamate, were elevated in hearts utilizing acetoacetate while succinyl-CoA was decreased suggesting impaired flux through the citric acid cycle at the level of 2-oxoglutarate dehydrogenase. Further studies indicated that the inhibition of 2-oxoglutarate dehydrogenase developed prior to the onset of contractile failure and that the inhibition of the enzyme may be related to sequestration of the required cofactor, coenzyme A, as the thioesters acetoacetyl-CoA and acetyl-CoA. The contractile failure was not observed when glucose, lactate, pyruvate, propionate, valine or isoleucine were present together with acetoacetate, but the addition of acetate or leucine to acetoacetate did not improve performance indicating that improved performance is not mediated through the provision of additional acetyl-CoA. Furthermore, addition of competing substrates that improved function did not relieve the inhibition of 2-oxoglutarate dehydrogenase and actually resulted in the further accumulation of citric acid cycle intermediates "upstream" of 2-oxoglutarate dehydrogenase (2-oxoglutarate, glutamate, citrate and malate). Studies with (1-$\sp{14}$C) pyruvate indicate that the utilization of ketone bodies is associated with activation of NADP$\sp+$dependent malic enzyme and enrichment of the C4 pool of the citric acid cycle. The results suggest that contractile failure induced by ketone bodies in rat heart results from inhibition of 2-oxoglutarate dehydrogenase and that reversal of contractile failure is dissociated from relief of the inhibition, but rather is due to the entry of carbon units into the citric acid cycle as compounds other than acetyl-CoA. This mechanism of enrichment (anaplerosis) provides oxaloacetate for condensation with acetyl-CoA derived from ketone bodies allowing continued energy production by sustaining flux through a span of the citric acid cycle up to the point of inhibition at 2-oxoglutarate dehydrogenase for energy production thereby producing the reducing equivalents necessary to sustain oxidative phosphorylation. ^

Sibling relationships in the family of a child with a burn injury

Purpose. Understanding siblings' experiences after a major childhood burn injury was the purpose of this mixed method, qualitative dominant study. The following research questions guided this project: How do siblings describe the impact of a major childhood burn injury experience? How do sibling relationship factors of warmth/closeness, relative status/power, conflict, and rivalry further clarify their relationship and their experience after a major burn injury? ^ Methods. A mixed method, qualitative dominant, design was implemented to understand the sibling experiences in a family with a child suffering from a major burn injury. Informants were selected from patients with childhood burn injuries attending the reconstructive clinic at a Gulf coast children's specialty hospital. The qualitative portion used the life story method, a narrative process, to portray the long-term impact on sibling relationships. A "case" represents a family unit and could be composed of one or multiple family members. Participants from 22 cases (N = 40 participants) were interviewed. Interviews were conducted in person and via telephone. The quantitative portion, or the embedded part of this mixed method design, used the Sibling Relationship Questionnaire Revised (SRQ-R) to conduct an additional structured interview and acquire scoring data. It was postulated that the SRQ-R would provide another perspective on the sibling experience and expand the qualitative data analysis. Thematic analysis was implemented on the qualitative interview data including the qualitative data from the interviews structured on the SRQ-R. Additionally, scores on the SRQ-R were tabulated to further describe the cases. ^ Results. The overall thematic pattern for the sibling relationship in families having a child with a major burn injury was that of normalization. Areas of normalization as well as the process of adjustment were the major themes. Areas of normalization were found in play and other activities, in school and work, and in family relations with their siblings and their parents. The process of adjustment in the sibling relationship was described as varied, involved school and work re-entry, and might even change their life perspective. Further analysis included an examination of the cases in which more than one person were interviewed and completed the SRQ-R. Participants from five ( n = 11) of six cases (n = 14), scored above 3.0 on the five-point scale on the Warmth/Closeness construct, indicating they perceived the sibling relationship as close. Five participants scored high on the Conflict construct and four participants scored high on the Rivalry construct. Finally, Relative Status/Power was low or negative in the six cases (n = 13). ^ Conclusions/implications. These findings suggest the importance of returning to normalcy for many of the families and the significance of sibling relationships on the process. Some of these families were able to use this major life event in a positive way to promote normalization. ^

The role of SRC family kinase activation in prostate cancer growth and lymph node metastasis

Aberrant expression and/or activation of Src Family of non-receptor protein tyrosine kinases (SFKs) occur frequently during progressive stages of multiple types of human malignancies, including prostate cancer. Two SFKs, Src and Lyn, are expressed and implicated in prostate cancer progression. Work in this dissertation investigated the specific roles of Src and Lyn in the prostate tumor progression, and the effects of SFK inhibition on prostate tumor growth and lymph node metastasis in pre-clinical mouse models. ^ Firstly, using a pharmacological inhibitor of SFKs in clinical trials, dasatinib, I demonstrated that SFK inhibition affects both cellular migration and proliferation in vitro. Systemic administration of dasatinib reduced primary tumor growth, as well as development of lymph node metastases, in both androgen-sensitive and -resistant orthotopic prostate cancer mouse models. Immunohistochemical analysis of the primary tumors revealed that dasatinib treatment decreased SFK phosphorylation but not expression, resulting in decreased cellular proliferation and increased apoptosis. For this analysis of immunohistochemical stained tissues, I developed a novel method of quantifying immunohistochemical stain intensity that greatly reduced the inherent bias in analyzing staining intensity. ^ To determine if Src and Lyn played overlapping or distinct roles in prostate cancer tumor growth and progression, Src expression alone was inhibited by small-interfering RNA. The resulting stable cell lines were decreased in migration, but not substantially affected in proliferation rates. In contrast, an analogous strategy targeting Lyn led to stable cell lines in which proliferation rates were significantly reduced. ^ Lastly, I tested the efficacy of a novel SFK inhibitor (KX2-391) targeting peptide substrate-binding domain, on prostate cancer growth and lymph node metastasis in vivo. I demonstrated that KX2-391 has similar effects as dasatinib, an ATP-competitive small molecular inhibitor, on both the primary tumor growth and development of lymph node metastasis in vivo, work that contributed to the first-in-man Phase I clinical trial of KX2-391. ^ In summary, studies in this dissertation provide the first demonstration that Src and Lyn activities affect different cellular functions required for prostate tumor growth and metastasis, and SFK inhibitors effectively reduce primary tumor growth and lymph node metastasis. Therefore, I conclude that SFKs are promising therapeutic targets for treatment of human prostate cancer. ^

Editoriall: A Holistic View of Family Preservation Services

One of the hallmarks of family preservation services is that they are holistic and attend to multiple dimensions of family life. In that spirit, this issue of the Family Preservation Journal provides a holistic view of these services, by offering research from the perspective of children, parents, caseworkers, and students of social work. These articles focus on the effectiveness of services, parents' perceptions of services, and the knowledge, attitudes and behavior of child welfare caseworkers. There should be something here for everyone who serves children and their families.

Highlighting the Importance of Researching Family Homelessness

This invited commentary responds to and builds upon Tobin and Murphy's article, “Addressing the Challenges of Child and Family Homelessness.” In affirming the ideas emerging from this article, Hallett and Tierney provide three points of extension: (1) more research needs to be conducted with doubled-up families; (2) the role of shame needs further exploration; and, (3) additional work needs to be done to increase access to postsecondary institutions.
