Abstract
Adolescence, a critical period of developmental period, is marked by neurobiological changes influenced by environmental factors. Here, we show how exposure to sucrose, which is ubiquitously available in modern diets, results in changes in behavioural response to cocaine as an adult. Rats were given daily access to either 10% sucrose or water during the adolescent period (PND28-42). Following this period, rats are left undisturbed until they reach adulthood. In adulthood, rats were tested for (i) acquisition of a low dose of cocaine, (ii) progressive ratio (PR) test, and (iii) resistance to punished cocaine taking. Sucrose exposure resulted in significant alterations in all behavioural measures. To determine the neurobiological mechanisms leading to such behavioural adaptations, we find that adolescent sucrose exposure results in an upregulation of the transcription factor Smad3 in the nucleus accumbens (NAc) when compared with water-exposed controls. Transiently blocking the active form of this transcription factor (HSV-dnSmad3) during adolescence mitigated the enhanced cocaine vulnerability-like behaviours observed in adulthood. These findings suggest that prior exposure to sucrose during adolescence can heighten the reinforcing effects of cocaine. Furthermore, they identify the TGF-beta pathway and Smad3 as playing a key role in mediating enduring and long-lasting adaptations that contribute to sucrose-induced susceptibility to cocaine. Taken together, these results have important implications for development and suggest that adolescent sucrose exposure may persistently enhance the susceptibility to substance abuse.

Abstract
Red cells (RBCs) of individuals with the In(Lu) gene are characterized by suppression of the Lutheran, P1, i, and other blood group antigens, acanthocytosis, and abnormal electrolyte metabolism. To determine the clinical significance of these abnormalities, the survival of autologous RBCs was determined by 51Cr in two siblings with the dominant Lu(a-b-) [In(Lu)] phenotype. Both subjects studied had normal hemoglobin, hematocrit, reticulocyte count, haptoglobin, and ferritin values. RBC indices were mildly hypochromic. Examination of the peripheral smear showed mild acanthocytosis in one individual. Analysis of RBC distribution on discontinuous density gradients showed a shift to lighter fractions than normal control RBCs. Storage of these Lu (a-b-) RBCs at 4 degrees C showed significant hemolysis within a few days; this was confirmed by increased autohemolysis, which was reduced by glucose and ATP. RBC cation content (sodium and potassium) was higher than that in control cells, which indicated increased cell hydration, which explains the lighter density and mild hypochromia of the Lu(a-b-) RBCs. 51Cr survival of autologous Lu(a-b-) RBCs was normal in both subjects studied. The data indicate that the morphologic and cation abnormalities of RBCs of persons with the In(Lu) gene are clinically insignificant, as these cells have normal in vivo survival. Such RBCs, however, are susceptible to increased hemolysis in vitro under standard blood banking storage conditions. Individuals of the Lu(a-b-) phenotype, associated with In(Lu), may not be suitable candidates for routine blood donation.

Abstract
Eighteen commercial bovine serum albumin (BSA) preparations were evaluated for their efficacy in hemagglutination enhancement by the capillary tube method. Their physicochemical variables (pH, conductivity, free fatty acids, total protein, and polymer content) were quantified. The results showed that a BSA preparation which consistently performed well in hemagglutination enhancement contained some albumin polymer and had a low free fatty acid content. We also found that the addition of Ficoll (final concentration of 1.24%) could convert BSA preparations producing mediocre hemagglutination enhancement into good enhancers, provided that these preparations did not have high free fatty acid content. Hence, the addition of Ficoll can obviate the requirement for selecting a polymer-enhanced albumin for use in capillary tube tests.

Abstract
Anti-Au, the first example of the antithetical antibody to anti-Au, was identified in the serum of a blood donor who had been transfused 16 years previously. Au has a gene frequency of 0.4326 in an American black population and 0.2994 in a southern English donor population. The expression of Au is suppressed by In(Lu). XS2 also suppresses Auberger antigen expression.

Abstract
A substantial number of individuals typed as HLA-B17 do not have Bgb. To determine whether or not this discrepancy reflects genetic or ethnic group differences or the influence of B17 antigen subtypes, a large number of unrelated and related B17 individuals from the Caucasian, Hispanic, Black and Chinese ethnic groups were tested in parallel for Bgb and Bw57- or Bw58- B17 subtype. Higher Bgb expression was found in association with Bw57, but differences in expression of Bgb were also seen in different ethnic groups and in different related individuals carrying the same Bw57 or Bw58 haplotype. Genetic factors other than HLA thus influence the expression of HLa Antigens on red cells. Standard and antiglobulin lymphocytotoxicity tests indicate that all Bgb typing sera contain anti-Bw57 antilymphocyte antibodies and most also contain anti-Bw58 and cross-reacting anti-B12, B15 and/or Bw49 antibodies.

Abstract
The manual capillary tube technique, in a series of 114 blood samples collected into CPD, demonstrated Bga on the red blood cells of 93 per cent of the HLA-B7 donors, and Bgb on the red blood of 80 per cent of the HLA-B17 donors. These results compare favorably with reported autoanalyzer studies. Successful results require normal red blood cell-plasma ratios in the samples and avoidance of heparin for collection.

Abstract
Antiglobulin reagents have been reported to increase the sensitivity of lymphocytotoxicity procedures for the detection of HLA antibodies that may affect the survival of transplanted kidneys or cause nonhemolytic transfusion reactions. This paper describes how such a procedure may also be used to demonstrate the presence of specific HLA antibodies in sera containing anti-Bg antibodies but lacking HLA antibodies that can be detected by conventional procedures. With the use of more sensitive procedures for the detection of both anti-Bg and HLA antibodies, studies of the relationship between specific HLA and Bg antigens can be extended, and the genetics of the expression of the Bg antigens can more easily be studied.
