Abstract
Background Angiotensin II (Ang II)–induced cardiac remodeling with the underlying mechanisms involving inflammation and fibrosis has been well documented. Cytosolic adaptor caspase recruitment domain 9 (CARD9) has been implicated in the innate immune response. We aimed to examine the role of CARD9 in inflammation and cardiac fibrosis induced by Ang II. Methods Two-month-old CARD9-deficient (CARD9−/−) and wild-type (WT) male mice were infused with Ang II (1,500 ng/kg/min) or saline for 7 days. Heart sections were stained with hematoxylin and eosin and Masson trichrome and examined by immunohistochemistry; and activity and protein levels were measured in macrophages obtained from mice. Results WT mice with Ang II infusion showed a marked increase in CARD9+ macrophages in the heart, but CARD9−/− mice showed significantly suppressed macrophage infiltration and expression of proinflammatory cytokines, including interleukin-1β (IL-1β) and connective tissue growth factor (CTGF). Importantly, Ang II–induced cardiac fibrosis (extracellular matrix and collagen I deposition) was diminished in CARD9−/− hearts, as was the expression of transforming growth factor-β (TGF-β) and level of myofibroblasts positive for α-smooth muscle actin (α-SMA). Furthermore, Ang II activation of nuclear factor-κB (NF-κB), JNK and p38 mitogen-activated protein kinases (MAPKs) in WT macrophages was reduced in CARD9−/− macrophages. Conclusion CARD9 plays an important role in regulating cardiac inflammation and fibrosis in response to elevated Ang II.

Abstract
A natural explanation for the carrier concentration-dependent electronic behavior in the layered cobaltates emerges within correlated-electron Hamiltonians with finite on-site and significant nearest neighbor hole-hole Coulomb repulsions. The nearest neighbor repulsion decreases hole double occupancy below hole density 1/3, but increases the same at higher hole densities. Our conclusion is valid for both single-band and three-band extended Hubbard Hamiltonians, and sheds light on concentration dependent e'(g) hole occupancy within the latter.

Abstract
Amyloid β-protein (Aβ) is central to the pathology of Alzheimer's disease. Of the two predominant Aβ alloforms, Aβ(1-40) and Aβ(1-42), the latter forms more toxic oligomers. C-terminal fragments (CTFs) of Aβ were recently shown to inhibit Aβ(1-42) toxicity in vitro. Here, we studied Aβ(1-42) assembly in the presence of three effective CTF inhibitors and an ineffective fragment, Aβ(21-30). Using a discrete molecular dynamics approach that recently was shown to capture key differences between Aβ(1-40) and Aβ(1-42) oligomerization, we compared Aβ(1-42) oligomer formation in the absence and presence of CTFs or Aβ(21-30) and identified structural elements of Aβ(1-42) that correlated with Aβ(1-42) toxicity. CTFs co-assembled with Aβ(1-42) into large heterooligomers containing multiple Aβ(1-42) and inhibitor fragments. In contrast, Aβ(21-30) co-assembled with Aβ(1-42) into heterooligomers containing mostly a single Aβ(1-42) and multiple Aβ(21-30) fragments. The CTFs, but not Aβ(21-30), decreased the β-strand propensity of Aβ(1-42) in a concentration-dependent manner. CTFs and Aβ(21-30) had a high binding propensity to the hydrophobic regions of Aβ(1-42), but only CTFs were found to bind the Aβ(1-42) region A2-F4. Consequently, only CTFs but not Aβ(21-30) reduced the solvent accessibility of Aβ(1-42) in region D1-R5. The reduced solvent accessibility of Aβ(1-42) in the presence of CTFs was comparable to the solvent accessibility of Aβ(1-40) oligomers formed in the absence of Aβ fragments. These findings suggest that region D1-R5, which was more exposed to the solvent in Aβ(1-42) than in Aβ(1-40) oligomers, is involved in mediating Aβ(1-42) oligomer neurotoxicity.

Abstract
WHAT IS KNOWN AND OBJECTIVE Clinical investigations into postoperative intravenous patient-controlled analgesia (PCA) have indicated interindividual differences in fentanyl consumption. Cytochrome P450 3A4 (CYP3A4) is the main metabolism enzyme of fentanyl, and single nucleotide polymorphisms within the CYP3A4 gene may contribute to the variability of fentanyl analgesic efficacy. The aim of this study was to investigate whether the most common genetic variation in Chinese, CYP3A4*1G, has an impact on the fentanyl consumption for intravenous PCA in Chinese Han women undergone abdominal total hysterectomy. METHODS A total of 79 female patients (American Society of Anesthesiologist physical status I or II) scheduled to undergo elective abdominal total hysterectomy were enrolled. All patients received combined spinal-epidural anaesthesia with bupivacaine. Intravenous fentanyl PCA was provided postoperatively for satisfactory analgesia. The doses of fentanyl consumption were recorded 2, 4, 24 and 48 h after the initiation of PCA postoperatively. Pain at rest and adverse effects were measured with rating scales. CYP3A4*1G was screened by means of direct sequencing and further confirmed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS AND DISCUSSION Forty-six patients were GG homozygotes, 27 patients were GA heterozygotes, and six patients were AA homozygotes, respectively. The distribution of the CYP3A4*1G allele was consistent with Hardy-Weinberg equilibrium (P>0·05). At 2 and 4 h, the doses of fentanyl required for patients with GA/AA genotypes were 80·0 (45·0, 112·5) μg and 120·0 (80, 173·8)μg, respectively, and significantly lower than those for GG homozygotes [91·3 (80·0, 125·0) μg and 169·0 (112·5, 226·3) μg, respectively, P<0·05]. There was trend of decreasing fentanyl consumption at 24 and 48h in patients with GA/AA genotypes, relative to GG homozygotes, but the difference was not statistical significant (P>0·05). WHAT IS NEW AND CONCLUSIONS CYP3A4*1G has an impact on the analgesic effect of fentanyl in Chinese Han subjects. Further validation of our results in a well-powered study would be helpful.

Abstract
Previously, a quantitative trait locus (QTL) that affects body weight (BW) at 4-12 weeks of age and carcass weight at 12 weeks of age had been mapped on chicken chromosome 1. After including more markers and individuals, the confidence interval was narrowed down to approximately 5.5 Mbps and located this QTL near a microsatellite marker (ADL328). This QTL is the same as the QTL for 12 bone traits, including metatarsus length and metatarsus circumference at 4, 6, 8, 10 and 12 weeks of age and keel length and metatarsus claw weight at 12 weeks of age, that was identified using the same population. In the current study, 1010 individuals from the Northeast Agricultural University F(2) resource population were used and 14 single-nucleotide polymorphism (SNPs) around ADL328 were developed to construct haplotypes, and an association analysis was performed to fine-map the QTL. The haplotypes were constructed on the basis of a sliding 'window', with three SNP markers included in each 'window'. The association analysis results indicated that the haplotypes in 'windows' 6-12 were significantly associated with BW and bone traits and suggested that the QTL for BW and bone traits was located between SNP8 and SNP14 or was in linkage disequilibrium with this region. The interval from SNP8 to SNP14 was approximately 400 kbps. This region contained five RefSeq genes (RB1, P2RY5, FNDC3A, MLNR and CAB39L) on the University of California Santa Cruz website. The RB1 gene was selected as a candidate gene and five SNPs were identified in the gene. The association results indicated that the RB1 gene was a major gene for BW and bone traits. The SNPs g.39692 G>A and g.77260 A>G in RB1 gene might be two quantitative trait nucleotides for BW and bone traits.

Abstract
BACKGROUND AND AIM Recent research suggests that low vitamin D may be associated with cardiovascular disease (CVD). METHODS AND RESULTS We prospectively evaluated the association of dietary plus supplemental vitamin D intake and serum 25(OH) vitamin D with CVD incidence in the Osteoporotic Fractures in Men (MrOS) Study. Vitamin D intake was measured using a food frequency questionnaire and self-reported supplemental intake in 3094 men (mean age 76.4 years). From a subset of this population, we measured 25(OH) vitamin D in 813 men. Median 25(OH) vitamin D was 25.3 ng/mL. During a median follow-up of 4.4 years, there were 472 CVD cases, including 371 from coronary heart disease (CHD) and 101 from cerebrovascular attack (CVA). In the 25(OH) vitamin D sub-cohort, there were 140 cases of CVD including 115 from CHD and 25 from CVA. We used a Cox proportional hazards regression to calculate hazard ratios (HR) for CVD by vitamin D quartile. After adjusting for age, season, and standard CVD risk factors, the lowest quartile of 25(OH) vitamin D (HR, 1.18; 95% CI, 0.69-2.03) and vitamin D intake (HR, 0.76; 95% CI, 0.56-1.04) were not significantly associated with CVD incidence, compared to the highest vitamin D quartiles. When 25(OH) vitamin D was further analyzed by sufficiency (≥30 ng/mL), insufficiency (≥15-29.9 ng/mL), and deficiency (<15 ng/mL), vitamin D deficiency was not significantly associated with CVD incidence compared to sufficiency (HR 1.34; 95% CI 0.65-2.77). CONCLUSION Vitamin D intake and serum 25(OH) vitamin D were not associated with CVD risk.
