Abstract
OBJECTIVES Although prior research has detected a step-gap in intergenerational relationships in various aspects, there is a lack of studies examining adult children's support toward their biological parents and stepparents. We investigated (i) whether adult children provide more support to their biological parents than stepparents and (ii) whether the childhood co-residence duration is associated with the support given to stepparents. METHODS The data were drawn from the German Family Panel (pairfam). Upward support was indicated by using 3 different measures, namely, financial, practical, and emotional support provided by adult children to their biological parents and stepparents. A path analysis was conducted to detect the potential differences regarding upward support. RESULTS More support was channeled toward the biological parents than the stepparents. Moreover, the length of co-residence during childhood and adolescence was positively associated with the frequency of support provided toward the stepparents. Consequently, an increased childhood co-residence duration decreased the step-gap in upward support, although it did not fully eliminate it. DISCUSSION The findings showed that stepparents are in a more disadvantaged position than the biological parents regarding receiving support from their adult children. In the context of a high old-age dependency ratio, it is important to recognize that stepparents may not have the opportunity to receive adequate support from their families as compared to individuals with biological children.

Abstract
To address claims of human exceptionalism, we determine where humans fit within the greater mammalian distribution of reproductive inequality. We show that humans exhibit lower reproductive skew (i.e., inequality in the number of surviving offspring) among males and smaller sex differences in reproductive skew than most other mammals, while nevertheless falling within the mammalian range. Additionally, female reproductive skew is higher in polygynous human populations than in polygynous nonhumans mammals on average. This patterning of skew can be attributed in part to the prevalence of monogamy in humans compared to the predominance of polygyny in nonhuman mammals, to the limited degree of polygyny in the human societies that practice it, and to the importance of unequally held rival resources to women's fitness. The muted reproductive inequality observed in humans appears to be linked to several unusual characteristics of our species-including high levels of cooperation among males, high dependence on unequally held rival resources, complementarities between maternal and paternal investment, as well as social and legal institutions that enforce monogamous norms.

Abstract
Abstract
Although grandparents are and have been important alloparents to their grandchildren, they are not necessarily only beneficial but can also compete with grandchildren over limited resources. Competition over parental care or other resources may exist especially if grandparents live in the same household with grandchildren and it can be dependent on grandchild age. By utilizing demographic data collected from historic population registers in Finland between 1761 and 1895 (study sample n = 4041) we investigate whether grandparents living in the same household with grandchildren are detrimental or beneficial for grandchild survival. Having a living but not co-residing grandmother or grandfather were both associated with better survival whereas having a co-resident grandfather was associated with lower chance to survive for infants (age < 1 year). Separating the effect between maternal and paternal grandparents and grandmothers and grandfathers revealed no differences in the effects between lineages. Negative effect of having a co-residing grandfather was not significant when grandfathers were separated for lineage specific models. These results implicate that accounting for the co-residence status and child’s age, grandparents were mostly beneficial when not co-residing with very young children and that having a co-residing grandfather at that age could be associated with lower chances to survive. Predictions made by grandmother hypothesis and resource competition both received support. The results presented here also offered comparison points to preindustrial and contemporary three-generational families.

Abstract
Demographers argue that human migration patterns are shaped by people moving to better environments. More recently, however, evolutionary theorists have argued that people move to similar environments to which they are culturally adapted. While previous studies analysing which factors affect migration patterns have focused almost exclusively on successful migrations, here we take advantage of a natural experiment during World War II in which an entire population was forcibly displaced but were then allowed to return home to compare successful with unsuccessful migrations. We test two competing hypotheses: (1) individuals who relocate to environments that are superior to their place of origin will be more likely to remain-The Better Environment Hypothesis or (2) individuals who relocate to environments that are similar to their place of origin will be more likely to remain-The Similar Environment Hypothesis. Using detailed records recording the social, cultural, linguistic and ecological conditions of the origin and destination locations, we find that cultural similarity (e.g. linguistic similarity and marrying within one's own minority ethnic group)-rather than ecological differences-are the best predictors of successful migrations. These results suggest that social relationships, empowered by cultural similarity with the host population, play a critical role in successful migrations and provide limited support for the similar environment hypothesis. Overall, these results demonstrate the importance of comparing unsuccessful with successful migrations in efforts understand the engines of human dispersal and suggest that the primary obstacles to human migrations and successful range expansion are sociocultural rather than ecological.

Abstract
PTLD is a well-recognized complication of organ transplantation. Large series of heart, renal, and liver transplants have been examined for the incidence and behavior of PTLD. However, reports of the incidence and characteristics of PTLDs in lung transplant (LTx) patients are few. We report our experience with PTLDs in a large series of LTx recipients at a single institution and compare them to other solid organ transplant recipient PTLDs seen at our institution. Twenty-eight patients were found to have PTLD, of whom 8 were lung transplant recipients. We evaluated nine PTLD specimens from these 8 patients for their histology, immunophenotype (CD20, CD3, EBV-LMP1), EBER status by in situ hybridization, and clinical features. The incidence of PTLD was 3.3% (8/244 patients). The time to development of PTLD, after transplant, was short (median time, 7 mo). All were of B-cell lineage. Overall, EBV was demonstrated in 77.7% (7 of 9 specimens) of PTLDs. All specimens tested for clonality were found to be monoclonal. Five patients died, with a median time to death of only 4.6 months. PTLDs in LTx patients are EBV-associated B-cell, predominantly monoclonal lymphoid lesions similar to other solid organ transplant PTLDs. Compared with other solid organ transplant recipients with PTLD at our institution, PTLDs in LTx patients have a propensity to involve the transplanted organ (P =.001, Fisher's exact test), occur earlier after transplant (P =.003, Wilcoxon test), and have a shorter survival (P =.002, log rank test). Reasons for this may include the relatively higher level of immunosuppression required in these patients and limited options in decreasing it. Although the incidence is low, careful early monitoring of lung transplantation patients is warranted because of the poor prognosis of patients developing this complication.

Abstract
Increasingly, molecular biologic techniques have become important in the diagnosis of non-Hodgkin lymphomas. In the differential diagnosis of lymphoma(s) of small lymphocytes (LSL), reliable detection of t(11;14) or t(14;18) would confirm the diagnosis of mantle cell lymphoma (MCL) or follicle center lymphoma (FCL), respectively. A total of 87 LSL cases (27 MCL, 39 FCL, 17 small lymphocytic lymphoma [SLL], 3 marginal zone lymphomas, and 1 paraimmunoblastic variant of SLL) were diagnosed by a combination of light microscopy, immunohistochemistry, and flow cytometric immunophenotyping. Interphase fluorescence in situ hybridization (FISH) for t(11;14) and t( 14;18) using dual-fusion probes (Vysis, Downers Grove, IL) was performed on touch (n = 69) or gravity (n = 18) preparations from these cases. Of 27 MCL cases tested, 25 (93%) had demonstrable t(11;14), none had t(14;18), and 2 were negative for t(11;14) and t(14;18). Twenty-five of 39 (64%) FCL cases had t(14;18), none had t(11;14), and the remaining FCL cases (14 cases [35%]) had neither t(11;14) nor t(14;18). All 17 (100%) SLL cases had neither t(11;14) nor t(14;18). All 3 (100%) marginal zone lymphoma cases had neither t(11;14) nor t(14;18). The case of paraimmunoblastic variant of SLL had t(11;14) and was negative for t(14;18). No discrepant [i.e., positive for both t(11;14) and t(14;18)] or false-positive cases were noted. Interphase FISH using these commercially available probes is a useful adjunct to light microscopy, immunohistochemistry, and flow cytometric immunophenotyping in the diagnosis of LSL. FISH can be performed successfully on archival single-cell preparations (touch preparations or gravity preparations) when fresh tissue is unavailable. No discordant or false-positive cases were identified.

Abstract
We compared the features of 17 cases of atypical chronic lymphocytic leukemia (aCLL) with those of a clinical control group of 24 cases of CLL. Quantitative flow cytometric data, available for 12 cases, were compared with an immunophenotypic control group of 58 cases using a relative fluorescence indexfor CD5, CD23, CD79b, and surface immunoglobulin light chain (sIg). Compared with the clinical control group, patients with aCLL had a higher mean WBC count and a lower platelet count. Patients with aCLL had a significantly higher probability of disease progression. Compared with an immunophenotypic control group of 58 CLL cases, 12 cases of aCLL demonstrated significantly higher expression of CD23. There was no significant difference in expression of sIg, CD79b, or CD5 between the groups. CD38 expression was noted in only 1 (9%) of 11 tested cases; 2 (18%) of 11 cases had trisomy 12. aCLL can be distinguished from typical CLL morphologically, clinically, and immunophenotypically. Atypical morphologic features in CLL seem to be a marker of aggressive clinical behavior.

Abstract
Primary cutaneous B-cell lymphomas (PCBLs) may have particular clinicopathologic characteristics distinct from their lymph node-based counterparts. It has been suggested that PCBLs should have a separate classification system. The aim of this study was to determine whether the Revised European-American Lymphoid Neoplasms (REAL) classification is applicable to PCBL. Thirty-nine cases of PCBL from 36 patients, consisting of 20 men and 16 women (median age 66 yrs), were included in this study. Paraffin-section immunohistochemistry for CD3, CD5, CD10, CD20, CD43, Bcl-2, Bcl-6, and cyclin D1 was performed in all cases. Immunostaining for immunoglobulin light chains was also performed on cases histologically diagnosed as extranodal marginal zone lymphoma (MZL) and primary cutaneous B-cell lymphoma unclassifiable (PCBLu). Polymerase chain reaction (PCR) analysis of t(14;18) was performed in all cases. Immunoglobulin heavy chain gene rearrangement (VDJ) was tested by PCR on all follicle center lymphoma (FCL), MZL, and PCBLu cases. The 39 cases consisted of 15 (39%) FCLs, 13 (33%) diffuse large B-cell lymphomas (DLCL), 9 (23%) extranodal MZL, and 2 cases of PCBLu. Anatomically, 59% of PCBLs occurred in the head and neck, of which approximately 57% were FCL. Five of six cases presenting on the lower extremity were DLCL. Follow-up data was available from all 39 patients with a mean of 50.8 months. All but two patients are alive with or without disease at last contact. One patient with DLCL died of lung metastases and the other DLCL patient died of sepsis as a complication of therapy. In all 15 cases of FCL, CD10 and/or Bcl-6 expression supported the follicle center origin of the neoplastic cells. In contrast to previous reports, we found that 53% (8 of 15) of primary cutaneous FCL had either Bcl-2 protein expression or t(14;18). Our data indicate that many cases of primary cutaneous FCL have Bcl-2 alterations similar to their nodal counterpart. We found that 95% (37 of 39) of PCBLs could be classified according to the REAL classification, supporting its applicability in cutaneous lymphomas.

Abstract
We sought the validation of a three-color fluorescence-based system that simultaneously profiles Her2/neu oncogene copy by fluorescence in situ hybridization (FISH) and Her-2/neu encoded protein by the use of a versatile alkaline phosphatase chromogen fast red K in either fluorescence or bright-field mode. Nuclei were counterstained with DAPI. Nineteen infiltrating ductal carcinomas of breast were comprehensively evaluated for Her-2/neu amplification/overexpression by direct and indirect FISH using digoxigenin (DigFISH) and direct fluorescently labeled probes, autoradiographic RNA:RNA in situ hybridization, and immunohistochemistry using monoclonal antibody CB11. CODFISH results correlated well with DigFISH, direct-label FISH, mRNA expression, and oncoprotein expression as assessed with CB11, and enabled simultaneous visualization of gene copy and protein. In addition, qualitative immunohistochemistry may be followed by CODFISH gene copy enumeration to clarify ambiguous cases.

Abstract
Neutral buffered formalin (NBF) (4% neutral buffered formaldehyde) has been advocated by most investigators as the primary fixative of choice for in situ hybridization (ISH), and specific anecdotal cautions interdicting the use of precipitating fixatives, which otherwise may offer certain advantages such as superior nuclear detail, are common. Few systematic studies addressing ISH fixation conditions have been published. We reasoned that heavy metals present in some precipitating fixatives may compromise duplex formation during ISH. Cell lines containing known viral gene content (CaSki, 200 to 600 human papilloma virus 16 copies/cell, and SiHa, 1 to 2 human papilloma virus 16 copies/cell) and two negative cell lines (K562 and MOLT 4) were expanded to >10(10) and pellets fixed in NBF, zinc formalin, B5, and Bouin's and Hollande's solutions, and subjected to DNA ISH using biotinylated genomic probes. Ten tissue biopsies fixed in both Hollande's and NBF solutions were also evaluated for human papilloma virus content using DNA ISH. Additionally, 17 cases of Hodgkin's disease fixed in B5 and formalin were compared for Epstein-Barr encoded RNA detection using RNA ISH with fluorescein isothiocyanate-labeled oligonucleotides. Catalyzed reporter deposition combined with Streptavidin-Nanogold staining and silver acetate autometallography (Catalyzed reporter deposition-Ng-autometallography ISH) and a conventional indirect alkaline phosphatase method were used for detection for both DNA and RNA. Contaminating heavy metals entrapped in fixed tissues were removed by two exposures to Lugol's iodine. Results for both DNA and RNA ISH comparing B5 and NBF fixatives were virtually identical. Hollande's, Bouin's, B5, and zinc formalin fixed tissue showed results indistinguishable from NBF fixed tissue in DNA ISH. Precipitating fixatives such as B5 and Hollande's solution may be used for DNA and RNA ISH under appropriate conditions.

Abstract
The t(9;22)(q34;q1 1) between the abl and bcr genes plays a pivotal role in the diagnosis and pathogenesis of chronic myelogenous leukemia (CML). Its detection is routinely accomplished by Southern blot analysis and karyotyping. Interphase fluorescence in situ hybridization (FISH) and reverse transcriptase-polymerase chain reaction (RT-PCR) are emerging molecular techniques that offer viable alternatives. We analyzed 40 samples of peripheral blood and bone marrow (CML, 16; acute myelogenous leukemia, 6; acute lymphoblastic leukemia [ALL], 1; chronic lymphoblastic leukemia, 2; myelodysplasias, 4; myeloproliferative disorders, unclassified, 3; nonleukemic hematologic malignancies, 3; hypercellular bone marrow, 1; normal control samples, 2; and K562 cell line samples, 2) for the presence of bcr-abl fusion gene and its messenger RNA (mRNA) transcript by FISH and RT-PCR, respectively. We compared the results with results of Southern blot analysis and karyotyping when available. Cost analysis was performed. Thirty-three samples were evaluable by FISH; 14 of 14 evaluable CML samples and one ALL sample were positive for bcr-abl by FISH (100%). The other 15 evaluable samples were negative; 16 of 16 (100%) and 13 of 16 (81%) of CML cases were positive for bcr-abl mRNA by RT-PCR (chemiluminescent blot method) and RT-PCR (colorimetric method), respectively. The ALL sample was positive by both RT-PCR methods. All other samples were negative by RT-PCR (chemiluminescent blot method), and all but 1 case of myeloproliferative disorder tested negative by RT-PCR (colorimetric method). We conclude the utility of FISH and RT-PCR is associated with certain limitations, such as insufficient RNA for RT-PCR and the occasional absence of internal positive FISH control signals. However, each procedure offers (with a high concordance rate) a specific and cost-effective alternative to Southern blot analysis and karyotyping and improved turnaround time for the detection of bcr-abl fusion gene or its mRNA transcript.

Abstract
Administration of multilamellar vesicles (MLV) encapsulating a synthetic peptide (RS-83277) derived from human C-reactive protein (CRP) augments anti-tumor activity of murine alveolar macrophages and reduces established pulmonary metastases of experimental tumors. To explore mechanisms involved in these phenomena, we investigated cytokine and integrin (CDllb) expression of bronchoalveolar lavage (BAL)-derived alveolar macrophages in control (blank MLV) and RS-83277-MLV-treated C57BI mice. Alveolar macrophage production of tumor necrosis factor alpha (TNF-alpha) and monocyte chemoattractant bioactivity increased at 48 h after treatment with RS-83277-MLV but not control MLV. Chemoattractant activity was neutralized by antibody to monocyte chemoattractant protein-1 (MCP-1), but not irrelevant immunoglobulin G(IgG). Changes were reflected by augmented TNF-alpha and MCP-1 mRNA levels in pulmonary tissue and enhanced CD11b expression on mononuclear leukocytes derived from total lung tissue, but not on BAL-derived alveolar macrophages. Results suggest that RS-83277-MLV treatment is associated with activation of alveolar macrophage TNF-alpha and MCP-1 production and up-regulation of adhesion molecules on pulmonary mononuclear leukocytes but not on alveolar macrophages.

Abstract
We previously reported that interleukin-4 (IL-4) inhibited proliferation of a human astrocytic cell line derived from non-neoplastic adult cortex. To determine whether this effect was receptor-associated and/or limited to only non-neoplastic astrocytes, we examined IL-4 responsiveness and receptor expression in human astrocytic cell lines derived from three different sources: non-neoplastic cerebral cortex (lines P1N, P2N, W3N); neoplastic low grade astrocytoma (LGA) (lines FRLGA, RTLGA); and highly malignant glioblastoma multiforme (GBM) (lines STTG1, CRTG2, WITG3, RUTG4). All lines except RUTG4 GBM expressed IL-4 receptor mRNA. Proliferation and DNA synthesis were markedly suppressed by IL-4 in a dose- and time-dependent manner in all non-neoplastic astrocyte and LGA lines, but not (0/4) GBM. This negative growth-regulatory effect of IL-4 was blocked by specific antibody to human IL-4 receptor but not by irrelevant IgG. In contrast, IL-4 stimulated interleukin-6 (IL-6) secretion in non-neoplastic astrocytes and LGA as well as in GBM cells expressing IL-4 receptor; secretion was undetectable in RUTG4 GBM which did not express receptor. These results indicate that: (i) responsiveness to IL-4 occurs in both non-neoplastic and neoplastic human astroglia; (ii) responsiveness is associated with IL-4 receptor expression; and (iii) sensitivity to negative growth signalling by IL-4 occurs selectively in astrocytes from non-neoplastic cortex or low grade neoplasia but not from highly malignant GBM.

Abstract
We reported previously that a synthetic peptide (RS-83277) derived from human C-reactive protein (CRP) augmented human monocyte/macrophage tumoricidal activity and cytokine production. RS-83287, a synthetic peptide derived from a different CRP site, was ineffective. Because chemoattractant properties have been attributed to some CRP-derived peptides, we hypothesized that RS-83277, in addition to activating effects, might promote human monocyte chemotaxis. Results indicated that neither CRP peptide RS-83277 nor RS-83287 was, itself, a chemoattractant. RS-83277, but not RS-83287, however, elicited time-dependent production of monocyte chemoattractant activity in conditioned media (CM) of cultured human mononuclear leukocytes and purified, adherent monocytes (MO). CM from nonadherent MO contained no activity, indicating that adherence was required for monocyte response. Monocyte chemoattractant activity was dose-dependent and was removed by treatment with immobilized antibody to human monocyte chemoattractant protein 1 (MCP-1) but not by irrelevant IgG. These results indicate that a specific peptide segment of CRP acts upon human adherent monocytes to promote production of the autocrine chemotactic and activating factor MCP-1. Data suggest that degraded CRP represents a complex source of biologically active peptides which, among other effects, may amplify monocyte recruitment to sites of injury.

Abstract
Infiltration of the central nervous system (CNS) by monocytes is a characteristic of many non-malignant disease processes, although the signals regulating such traffic are unclear. Tumor necrosis factor (TNF) and other inflammatory cytokines have been shown to elicit production of monocyte chemoattractant activity in glioma cells, but the regulation of such activity in non-neoplastic adult astrocytes has not been examined. We previously observed that TNF constituted a proliferative signal for non-neoplastic adult human astrocytes in vitro involving the 55-kDa TNF receptor. In the present study, we demonstrate that TNF exposure enhances the expression of monocyte chemoattractant protein-1 (MCP-1) mRNA and functional monocyte chemoattractant activity in non-neoplastic astrocytes. Results indicated that MCP-1 mRNA expression was maximal within 3 h, and was further augmented by the protein synthesis inhibitor cycloheximide (CY). Antibody (htr-9) directed against the 55-kDa TNF receptor also elicited MCP-1 mRNA expression while antibody to the 75-kDa TNF receptor (utr-1) was ineffective. Secretion of monocyte chemoattractant activity was significantly greater in TNF- or htr-9-treated astrocytes than in utr-1-treated or untreated controls; activity was abolished by treatment with antibody to MCP-1. These findings suggest that non-neoplastic adult human astrocytes may contribute to CNS inflammatory responses by mediating recruitment of peripheral blood monocytes.

Abstract
We have shown previously in several mouse tumor systems that multilamellar vesicles (MLV) are an effective delivery system for generation of macrophage-mediated tumoricidal activity by C-reactive protein (CRP). Here we show that resealed erythrocyte ghosts (red cell ghosts, RCG) can function in the same manner. CRP associated with red cell ghosts (CRP-RCG) inhibited established lung metastases of T241 fibrosarcoma in C57B1/6J mice. The degree of inhibition was comparable to that observed with CRP-MLV. In other experiments, peritoneal exudate cells, obtained from mice pretreated with CRP-RCG i.p., inhibited growth and pulmonary metastases of T241 tumor in the Winn neutralization assay. Similar results were obtained with MCA-38 colon carcinoma in the Winn assay. These studies indicate that erythrocytes deserve consideration as another delivery system for biological response modifiers.
