Abstract
UNLABELLED Hepatitis B virus (HBV) is a major etiological factor of hepatocellular carcinoma (HCC). However, the postoperative prognostic value of the virological factors assayed directly from liver tissue has never been investigated. To address this issue, 185 liver samples obtained from the noncancerous part of surgically removed HBV-associated HCC tissues were subjected to virological analysis. Assayed factors included the amount of HBV-DNA in the liver tissues; genotype; and the presence of the HBV precore stop codon G1896A mutation, basal core promoter A1762T/G1764A mutation, and pre-S deletions/stop codon mutation. All virological factors and clinicopathological factors were subjected to Cox proportional hazard model analysis to estimate postoperative survival. It was found that an HBV-DNA level >3.0 × 10(7) copies/g of liver tissue and the presence of the basal core promoter mutation independently predicted disease-free (adjusted hazard ratio 1.641 [95% confidence interval (CI) 1.010-2.667] and 2.075 [95% CI 1.203-3.579], respectively) and overall (adjusted hazard ratio 2.807 [95% CI 1.000-7.880] and 5.697 [95% CI 1.678-19.342], respectively) survival. Kaplan-Meier survival analysis indicated that in-frame, short stretch (<100 bp) pre-S deletions, but not large fragment (>100 bp) pre-S deletions, were significantly associated with poorer disease-free (P = 0.005) and overall (P = 0.020) survival. A hot deletion region located between codons 107 and 141 of the pre-S sequence was identified for the short stretch pre-S deletion mutants. CONCLUSION The amount of HBV-DNA in liver tissue and the presence of the basal core promoter mutation were two independent predictors for postoperative survival in HCC. A short stretch pre-S deletion located between codons 107 and 141 was strongly associated with a poorer postoperative prognosis.

Abstract
High-resolution DNA sequencing was used to identify the human leukocyte antigen (HLA) -A, -B, -C, and -DRB1 alleles found in 552 individuals from the United States indicating Southern European (Italian or Spanish) heritage. A total of 46 HLA-A, 80 HLA-B, 32 HLA-C, and 50 DRB1 alleles were identified. Frequent alleles included A*02:01:01G (allele frequency = 0.26 in Italian Americans and 0.22 in Spanish Americans); B*07:02:01G (Italian Americans allele frequency = 0.11); B*44:03 (Spanish Americans allele frequency = 0.07); C*04:01:01G and C*07:01:01G (allele frequency = 0.13 and 0.16, respectively, in Italian Americans; 0.15 and 0.12, respectively, in Spanish Americans); and DRB1*07:01:01 (allele frequency = 0.12 in each population). The action of balancing selection was inferred at the HLA-B and -C loci in both populations. The A*01:01:01G-C*07:01:01G-B*08:01:01G-DRB1*03:01:01 haplotype was the most frequent A-C-B-DRB1 haplotype in Italian Americans (haplotype frequency = 0.049), and was the second most frequent haplotype in Spanish Americans (haplotype frequency = 0.021). A*29:02:01-C*16:01:01-B*44:03-DRB1*07:01:01 was the most frequent A-C-B-DRB1 in Spanish Americans (haplotype frequency = 0.023), and was observed at a frequency of 0.015 in Italian Americans. Pairwise F'(st) values measuring the degree of differentiation between these Southern European American populations as well as European and European American populations suggest that Spanish Americans constitute a distinct subset of the European American population, most similar to Mexican Americans, whereas Italian Americans cannot be distinguished from the larger European American population.

Abstract
We report the observation of 16 cosmic ray events with a mean energy of 1.5 × 10¹⁹ eV via radio pulses originating from the interaction of the cosmic ray air shower with the Antarctic geomagnetic field, a process known as geosynchrotron emission. We present measurements in the 300-900 MHz range, which are the first self-triggered, first ultrawide band, first far-field, and the highest energy sample of cosmic ray events collected with the radio technique. Their properties are inconsistent with current ground-based geosynchrotron models. The emission is 100% polarized in the plane perpendicular to the projected geomagnetic field. Fourteen events are seen to have a phase inversion due to reflection of the radio beam off the ice surface, and two additional events are seen directly from above the horizon. Based on a likelihood analysis, we estimate angular pointing precision of order 2° for the event arrival directions.

Abstract
Crab zoeae (Rhithropanopeus harrisii) were exposed to water-soluble fractions of jet fuel (JP5) for the first 5 days or for the duration of zoeal development (11 to 14 days). Short-term exposure or continuous exposure to low concentrations of petroleum hydrocarbons caused no increase in mortality or changes in development rate, and increased megalopal weight was characteristic of such groups. This phenomenon, termed "hormesis," is probably a generalized aspect of environmental stress etiology but has seldom been reported as such.

Abstract
KIR2DL5 alleles were physically linked to alleles at adjacent KIR loci to define this region of KIR haplotypes in 55 gene-positive random African Americans. The majority carried KIR2DL5B. Three KIR2DL5A and six KIR2DL5B alleles that have been previously described and 11 novel KIR2DL5 alleles were identified by DNA sequencing. Novel alleles included variation that may impact promoter activity; two alleles carried nonsynonymous coding region variation. Based on linkage with KIR2DS1, KIR2DS3, KIR2DS5, KIR2DL2, KIR2DL3, and KIR3DS1 alleles, seven haplotypes of KIR2DL5A and 23 haplotypes of KIR2DL5B were observed. The phylogenetic relationships among the KIR2DL5 alleles predicted their association with either KIR2DS3 (six alleles) or KIR2DS5 (seven alleles). All of the KIR2DL5A alleles were linked either to KIR3DS1*01301 or KIR3DS1*049N. The majority of the KIR2DL5B alleles were linked to seven KIR2DL2 alleles; two were linked to a novel allele of KIR2DL3. These findings underscore the diversity of KIR haplotypes present in this population.

Abstract
KIR3DL1 and KIR3DS1 allele frequencies were determined by DNA sequencing of the complete coding regions from 100 random unrelated African Americans. Alleles 3DL1*01501 (29 individuals) and 3DL1*01502 (23 individuals) were most frequently observed in addition to 21 other known alleles and 7 new alleles: KIR3DL1*01503, *03102, *064, *065, *066, *067, and *068. Two of the new alleles (KIR3DL1*064, *065) created additional variants of the chimeric KIR3DL1/KIR3DL2 gene. KIR3DS1*01301 (94% of the gene positive individuals) and KIR3DS1*049N (11%) were identified in the 18 individuals carrying this gene. Three individuals appeared to carry a killer cell immunoglobulin-like receptor haplotype with KIR3DL1/S1 duplication. The profile of alleles resembles that found in African populations but also shows signs of admixture.

Abstract
Sotrastaurin, a novel protein-kinase-C inhibitor, blocks early T-cell activation. In this 12-month, Phase II study, de novo renal-transplant patients were randomized to sotrastaurin (200 mg b.i.d.) + standard-exposure tacrolimus (SET) or reduced-exposure tacrolimus (RET) (SET: n = 76; RET: n = 66), or control (SET + mycophenolic acid [MPA, 720 mg b.i.d.]; n = 74). In both sotrastaurin groups, patients were converted from tacrolimus to MPA after Month 3, achieving calcineurin inhibitor-free immunosuppression. The primary endpoint was composite efficacy failure (treated biopsy-proven acute rejection, graft loss, death or loss to follow-up). The key secondary endpoint was glomerular filtration rate (GFR). Composite efficacy failure rates were: 4.1%, 5.4% and 1.5% at Month 3 (preconversion) and 7.8%, 44.8% and 34.1% at study end in the control, sotrastaurin + SET and sotrastaurin + RET groups, respectively; these results led to premature study discontinuation. Median GFR at Month 6 was: 57.0, 53.0 and 60.0 mL/min/1.73 m(2), respectively. Study-drug discontinuations due to adverse events occurred in 16.2%, 18.4% and 12.1%, respectively. Leukopenia and neutropenia occurred more frequently preconversion in control versus sotrastaurin groups: 13.7%, 5.6%, and 4.6%; and 11.1%, 4.3% and 3.1%, respectively. The initial sotrastaurin + tacrolimus regimen was efficacious and well tolerated but the postconversion sotrastaurin + MPA regimen showed inadequate efficacy. Longer-term evaluation of sotrastaurin + tacrolimus is warranted.

Abstract
OBJECTIVE The investigators tested the hypothesis that maternal-fetal immune interactions could be important in initiating spontaneous labor onset by examining if labor was delayed when fetuses share maternal HLA antigen types. STUDY DESIGN HLA antigen types A, B, and DR in 200 Danish mother-infant pairs delivering in 42-44 weeks (postterm) were compared with 195 mother-infant pairs delivering in 37-40 weeks (term). RESULTS Sharing of HLA A and B antigens was more common than expected in postterm deliveries. Odds ratios were 1.54 (95% confidence interval [CI], 1.01-2.35) and 1.75 (95% CI, 0.87-3.52), respectively (risk per shared antigen: 1.40 [95% CI, 1.04-1.90] per unit increase). Adding stringent birth-length criteria for postmaturity (92 cases; 168 controls) strengthened risks associated with antigen sharing to 1.57 (95% CI, 0.90-2.74) and 2.60 (95% CI, 1.15-5.88), respectively (risk per shared antigen: 1.60 (95% CI, 1.10-2.32). CONCLUSION Postterm-delivered infants had more HLA A and B antigens in common with their mothers, suggesting that recognition of HLA antigen differences by adaptive immunity may have a role in triggering labor onset.

Abstract
Synaptic plasticity in the striatum is a key mechanism that underlies processes such as reward related incentive learning and behavioral habit formation resulting from drugs of abuse. Key aspects of these functions are dependent on dopamine transmission as well as activation of calcium/calmodulin-dependent protein kinase IIalpha (CaMKIIalpha). In this study, we examined the ability of a recently identified heteromeric complex composed of D1 and D2 dopamine receptors coupled to Gq/11 to activate striatal CaMKIIalpha. Using the dopaminergic agonist SKF83959, which selectively activates the D1-D2 complex, we demonstrated phosphorylation of CaMKIIalpha at threonine 286, both in heterologous cells and in the murine striatum in vivo. Phosphorylation of CaMKIIalpha by activation of the receptor complex required concurrent agonism of both D1 and D2 receptors and was independent of receptor pathways that modulated adenylyl cyclase. The identification of this novel mechanism by which dopamine may modulate synaptic plasticity has implications for our understanding of striatal-mediated reward and motor function, as well as neuronal disorders in which striatal dopaminergic neurotransmission is involved.

Abstract
We report three novel small RNA viruses uncovered from cDNA libraries from parasitoid wasps in the genus Nasonia. The genome of this kind of virus is a positive-sense single-stranded RNA with a 3' poly(A), which facilitates cloning from cDNAs. Two of the viruses, NvitV-1 and NvitV-2, possess a RNA-dependent RNA polymerase that associates them with the family Iflaviridae of the order Picornavirales. A third virus, NvitV-3, is most similar to the Nora virus from Drosophila. A reverse transcription-PCR method developed for NvitV-1 indicates that it is a persistent commensal infection of Nasonia.

Abstract
Immune maladaption between mother and infant has been suggested to induce preeclampsia/eclampsia. When fetuses share more human leukocyte antigen (HLA) types with their mother, immune differences would be limited and thereby could affect this risk. Data from Danish women (1996-2002) with single live-birth pregnancies complicated by severe preeclampsia/eclampsia were compared to women with term pregnancies uncomplicated by hypertension. HLA A, B, and DR types were resolved at the intermediate-level typing (antigen). A total of 201 cases and 195 control mother-infant pairs had complete HLA types. The odds ratios of preeclampsia/eclampsia in mothers sharing both HLA antigens with their infants were 1.19 (95% confidence interval: 0.81-1.76) for HLA A, 0.91 (0.59-1.42) for HLA B, and 1.05 (0.5-1.59) for HLA DR antigens. No specific HLA antigens in either mother or infant appeared important after Bonferroni correction, except possibly DR01 in mothers (protective). Thus, maladaption mediated by adaptive immunity between mother and infant is not the basis for the mother developing preeclampsia/eclampsia.
