Abstract
Experimental studies of nuclear fission induced by fusion, transfer, spallation, fragmentation, and electromagnetic reactions in combination with state-of-the-art calculations are successful to investigate the nuclear dissipation mechanism in normal nuclear matter, containing only nucleons. The dissipation mechanism has been widely studied by the use of many different fission observables and nowadays the dissipation coefficients involved in transport theories are well constrained. However, the existence of hypernuclei and the possible presence of hyperons in neutron stars make it necessary to extend the investigation of the nuclear dissipation coefficient to the strangeness sector. In this Letter, we use fission reactions of hypernuclei to constrain for the first time the dissipation coefficient in hypernuclear matter, observing that this coefficient increases a factor of 6 in the presence of a single Λ hyperon with respect to normal nuclear matter.

Abstract
Taking benefit of the R3B/SOFIA setup to measure the mass and the nuclear charge of both fission fragments in coincidence with the total prompt-neutron multiplicity, the scission configurations are inferred along the thorium chain, from the asymmetric fission in the heavier isotopes to the symmetric fission in the neutron-deficient thorium. Against all expectations, the symmetric scission in the light thorium isotopes shows a compact configuration, which is in total contrast to what is known in the fission of the heavier thorium isotopes and heavier actinides. This new main symmetric scission mode is characterized by a significant drop in deformation energy of the fission fragments of about 19 MeV, compared to the well-known symmetric scission in the uranium-plutonium region.

Abstract
Spectroscopic factors of neutron-hole and proton-hole states in ^{131}Sn and ^{131}In, respectively, were measured using one-nucleon removal reactions from doubly magic ^{132}Sn at relativistic energies. For ^{131}In, a 2910(50)-keV γ ray was observed for the first time and tentatively assigned to a decay from a 5/2^{-} state at 3275(50) keV to the known 1/2^{-} level at 365 keV. The spectroscopic factors determined for this new excited state and three other single-hole states provide first evidence for a strong fragmentation of single-hole strength in ^{131}Sn and ^{131}In. The experimental results are compared to theoretical calculations based on the relativistic particle-vibration coupling model and to experimental information for single-hole states in the stable doubly magic nucleus ^{208}Pb.

Abstract
Excitation spectra of ^{11}C are measured in the ^{12}C(p,d) reaction near the η^{'} emission threshold. A proton beam extracted from the synchrotron SIS-18 at GSI with an incident energy of 2.5 GeV impinges on a carbon target. The momenta of deuterons emitted at 0° are precisely measured with the fragment separator (FRS) operated as a spectrometer. In contrast to theoretical predictions on the possible existence of deeply bound η^{'}-mesic states in carbon nuclei, no distinct structures are observed associated with the formation of bound states. The spectra are analyzed to set stringent constraints on the formation cross section and on the hitherto barely known η^{'}-nucleus interaction.

Abstract
Strong evidence suggests that microbial components are involved in the etiopathology of inflammatory bowel diseases (IBD). Since pathogen-associated molecular patterns are recognized by TLRs, dysregulation of TLR-mediated microbial recognition could be taking place in IBD patients. An in vitro assay with different TLR agonists was used to reproduce the immunostimulation via TLR ligands. Elevated TNFalpha production was found in response to LTA and Zymosan in 48% of active Crohn's disease and ulcerative colitis patients when compared to inactive patients or controls. The expression of CD14 did not differ in active patients, whereas TLR2 was significantly upregulated on monocytes from 71% of those patients with high production of TNFalpha. The marked increase of TNFalpha response to TLR2 ligands correlated with a higher TLR2 expression in a group of IBD patients, suggesting that an abnormal mechanism may provide an excess of inflammatory mediators during the active phase of IBDs.

Abstract
BACKGROUND Umbilical cord blood (UCB) cells have been increasingly used as a source of hematopoietic stem cells for allogeneic transplantation. Previous reports suggest that the low risk of graft-versus-host disease in patients that received cord blood cells seems related to the distinctive nature of cord blood T cells. METHODS To analyze the maturation of CD4+CD45RA+ cord blood cells, we performed an in vitro differentiation assay to compare the generation of Th effector cells strictly from UCB and adult peripheral blood (APB) CD4+CD45RA+ cells. RESULTS During the maturation into effector cells, UCB and APB cells acquired a comparable activation level determined by the expression pattern of CD69, CD40L, OX40 and CD62L as well as PD1 and CTLA-4 molecules. Moreover, the expression of CD45RO isoform was induced in most activated effector cells from both UCB and APB. OKT3-restimulated effector cells generated from naive UCB expressed higher levels of CD25 coinciding with the secretion of higher amounts of IL-2. Effector cells from both origins consisted of heterogeneous populations with similar frequencies of Th1 and Th2 cytokine producing cells, secreting equivalent levels of IL-4, IL-5 and IFNgamma. Although, higher levels of IL-10 were detected in the cytokine mRNA profile and in the supernatants of OKT3-restimulated UCB effector cells, blocking endogenous IL-10 with anti-IL-10 mAbs enhanced significantly the proliferative response of UCB as well as APB effector cells (P < 0.05). CONCLUSIONS These results indicated that Th effector cells generated from naive UCB cells were intrinsically as competent as naive APB to respond to TCR-mediated stimulation. In addition, UCB effector cells produced higher IL-10 but its inhibitory effect on proliferation may be partially compensated by the higher production of IL-2 and enhanced expression of CD25.

Abstract
We report here the sequence of an HLA B*15 allele, B*1573. Initially, a cord blood unit from the Umbilical Cord Bank of Barcelona was typed by sequence-specific oligonucleotide hybridization and revealed an unusual hybridization pattern. After the cloning, the sequence-based typing assigned two different alleles: B*07021, and a second allele identical to B*1558 in exons 2 and 3, except for a single nucleotide substitution in exon 3, which changed codon 140 from Phe to Leu (TTX-->TTA).

Abstract
We report a novel HLA-B*41 allele (HLA-B*4106) initially detected by an unusual sequence-specific oligonucleotide (SSO) hybridization pattern and identified by sequence-based HLA typing. Molecular cloning and sequencing determined that the new HLA-B allele was identical to the HLA-B*4101 in exon 2 and 3 except for a single nucleotide substitution in the exon 3 changing codon 204 from Glu to Gln (GAG-->CAG). In addition, intron 2 was identical to the published HLA-B*4104 intron 2, except for the base 509 (C-->G).

Abstract
We previously described autoantibodies against a UGA serine tRNA-protein complex (tRNP(Ser)Sec) in patients with type-1 autoimmune hepatitis [1] and now define the specificity and frequency of this autoantibody and the DNA sequence encoding the tRNA(Ser)Sec-associated antigenic protein. The presence of anti-tRNP(Ser)Sec antibodies was highly specific for type-1 autoimmune hepatitis, as 47.5% of patients were positive compared with none of the control subjects. To characterize the antigenic protein(s), we immunoscreened a human cDNA library with anti-tRNP(Ser)Sec-positive sera. Two clones (19 and 13) were isolated. Clone 19 encodes a protein with a predicted molecular mass of 48.8 kD. Clone 13 is a shorter cDNA, almost identical to clone 19, which encodes a 35.9-kD protein. Expression of both cDNAs was accomplished in Escherichia coli as His-tagged recombinant proteins. Antibodies eluted from both purified recombinant proteins were able to immunoprecipitate the tRNA(Ser)Sec from a HeLa S3 cell extract, demonstrating their cross-reactivity with the mammalian antigenic complex. Recent cloning data relating to the target antigen(s) of autoantibodies in autoimmune hepatitis patients that react with a soluble liver antigen (SLA) and a liver-pancreas antigen (LP) have revealed that these two autoantibodies are identical and that the cloned antigen shows 99% amino acid sequence homology with tRNP(Ser)Sec.

Abstract
Mice injected at birth with semiallogeneic spleen cells develop a host-versus-graft disease (HVGD) characterized by the polyclonal activation of donor B cells by alloreactive host CD4+ T cells, the production of autoantibodies (autoAb) and the development of an inmmunocomplex-mediated glomerulonephritis. It has been demonstrated that the recognition of MHC class II, but not class I or non MHC, alloantigens triggers the development of the autoimmune syndrome (AIS). The finding of different expression patterns of Ia molecules in different mouse strains, and a closed restriction of some immune responses to particular H-2 haplotypes, prompted us to analyze whether variations in the expressed MHC class II molecules modify the HVGD. First, newborn BALB/c mice received spleen cells from F1 hybrid mice obtained by mating BALB/c mice with several mouse strains differing in the H-2 haplotype. Second, spleen cells from different F1 mice were neonatally injected in mice of both parental strains. All groups of BALB/c mice injected with different combinations of F1 mice showed an HVGD with a very similar serological course. However, in some instances, duration was different when comparing both parental strains injected with spleen cells from the mutual F1 hybrids. These results suggest that host MHC, but not donor MHC haplotype may modulate the AIS associated with the induction of neonatal tolerance.

Abstract
We report a patient with reticular dysgenesis (RD) who received an HLA-identical marrow graft and remained free of infection in spite of incomplete haematological recovery. Mixed chimerism was achieved and resulted from the presence of autologous B cells and monocytes and grafting of donor T cells. Granulocyte recovery was impaired. The B cells were CD5+ (B1 cells) and appeared to be functional, since serum immunoglobulin levels became normal after the graft. The findings described here suggest that in some cases the defect selectively affects different cell types, including the more abundant leucocyte populations, granulocytes and T lymphocytes. However, B cells and monocytes appear to be relatively spared in this case of RD. Furthermore, the present case may provide insight into the mechanism involved in the expansion of distinct B cell subpopulations (B1 and B2 cells).

Abstract
We describe the immunologic findings in a patient with the antisynthetase syndrome characterized by prominent arthritis, lung fibrosis, and subclinical myositis. At disease onset and during the followup, this patient's serum showed 2 different subsets of antisynthetase autoantibodies: anti-Jo-1, which reacted with histidyl-transfer RNA (tRNA) synthetase by immunoblot and inhibited its enzymatic function; and anti-0J, which immunoprecipitated the multi-enzyme complex of synthetases, and reacted with lysyl-tRNA synthetase by immunoblot. This is the first report of anti-Jo-1 and another antisynthetase antibody being found together in the same patient.

Abstract
To investigate the role of donor T lymphocyte subsets in the development of chronic graft-vs-host disease (GVHD) induced in (BALB/c x A/J)F1 (CAF1) mice by injecting BALB/c lymphoid cells, we analyzed the effect that CD8+ cell removal from donor inoculum has on the manifestation of the disease. Compared with age- and sex-matched CAF1 mice injected with whole lymphocyte inoculum, CAF1 mice injected with CD8(+)-depleted inoculum exhibited: 1) a higher incidence and exacerbation of nephritis by immunocomplexes; 2) higher (five- to sevenfold) spontaneous IL-4 production; 3) higher frequency titer and precocity of anti-dsDNA, anti-histone, and IgM and IgG rheumatoid factors; 4) a dramatic change in the frequency and titer of anti-U1 small nuclear ribonucleoprotein Abs; and 5) a markedly decreased engraftment (10- to 15-fold) on BALB/c donor lymphocytes. In contrast, rheumatoid arthritis-like disease, a later clinical manifestation of the GVHD in CAF1 + BALB/c model, is not present in the CD8(+)-depleted model (CAF1 + CD8-BALB/c). Considered together, these data suggest that CD8+ donor T lymphocytes play an important role in the degree of chimerism, modulation of the response to autoantigens, and clinical aspects developed in the GVHD model presented here.

Abstract
During the study of autoimmune models we found that (SWR x SJL)F1 mice (both parental strains with the V beta a phenotype) spontaneously produced immunoglobulin G (IgG) antibodies directed against Sm/U1 small nuclear ribonucleoproteins (snRNPs). In some of these females, the presence of these autoantibodies was found as early as 10 wk of age. Their frequency increased with age i.e., 70% at 40 wk. At that time, only 10% of males developed anti-Sm/U1snRNP antibodies. Anti-Sm/U1snRNP antibodies from positive mice generally recognized the peptides BB', D, 70 kD, and A from RNPs. These polypeptides are known to bear the autoantigenic epitopes that are recognized by human sera containing anti-Sm and anti-U1snRNP antibodies. Reactivity of IgG antibodies with the octapeptide sequence PPPGMRPP was also found in 30% of anti-Sm/U1snRNP positive (SWR x SJL)F1 mice that precipitated BB' peptides. This octapeptide has been described as the most immunoreactive linear epitope in systemic lupus erythematosus (SLE) patients with anti-Sm and anti-U1snRNP antibodies. Approximately 30% of anti-Sn/U1snRNP positive females, later produced anti-dsDNA antibodies. This fact was accompanied by the development of proteinuria due to glomerulonephritis mediated by immunocomplexes. In addition to the specific autoimmune response, (SWR x SJL)F1 females also showed other immunologic abnormalities such as hypergammaglobulinemia, and an approximately twofold increase in spleen cell number compared with control mice. These results indicate that (SWR x SJL)F1 females develop clinical and serological abnormalities similar to those observed in human SLE and constitute a novel model for the study of the genetic mechanisms that result in autoimmunity.
