Notizen: The implications of adoption for the emotional and behavioral adjustment of children have been an issue in child welfare for many years. Past research has suggested that adopted children are over-represented in mental health settings. In addition, some studies have suggested that adopted and nonadopted children differ on measures of social, emotional, behavioral, and cognitive functioning. The current study used data from a large, representative sample in the United States to examine whether adopted children are more likely to have had mental health contacts or emotional or behavioral problems than nonadopted children. Age of placement in the adoptive home was examined as a variable contributing to the adjustment of adopted children. Results suggest that adopted and foster children are more likely to have mental health contacts than nonadopted children. Results are mixed regarding whether adopted and foster children have more behavior problems than nonadopted children. However, significant differences between adopted, foster, and nonadopted children disappeared when a small group of influential cases were removed. This suggests that the differences seen between the groups reflect a small number of cases and are not representative of the groups of adoptees and foster children as a whole. The vast majority of adopted children showed patterns of behavior problems similar to those of nonadopted children. These results are discussed in relation to the past literature and areas for future research.

Notizen: [Auszug] The nonapeptide, NH2-Gln-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn-COOH, was synthesised using solid-phase methodology (Peninsula, San Carlos, California). The purified peptide showed a single spot in four thin-layer chromatography systems and on high voltage electrophoresis at pH 6.5. After acid hydrolysis, ...

Notizen: Abstract Alloantisera were prepared by reciprocal immunizations with bursal or thymic lymphoid cells between chickens of two inbred lines identical at theB major histocompatibility locus. In cytotoxic assays, antibursa sera were specific for donor-line bursa cells without absorption; antithymus sera were similarly specific for donor-line thymus cells. Both types of sera cytolyzed some peripheral lymphoid cells from spleen, bone marrow, and blood. Absorption of either type of serum with peripheral blood leukocytes removed all cytotoxic reactivity for central lymphoid cells. The inheritance of the alloantigens detected by these specific antisera was studied in F1, F2, and backcross progeny from the two lines. Phenotypes were determined by a method in which antisera preabsorbed with progeny leukocytes were reacted against51Cr-labeled bursal or thymic cells from chickens of both lines. The results established two independent autosomal loci-Bu-1 andTh-1-determining antigens expressed, respectively, on bursal cells and peripheral B lymphocytes or on thymic cells and peripheral T lymphocytes. Cytotoxic testing of bursal or thymic cells from chickens of other inbred lines and F1 populations led to the tentative conclusion that the number of alleles atBu-1 is restricted, whileTh-1 exhibits considerable multiple allelism.
