Abstract
BACKGROUND HBV infection causes chronic liver disease and leads to the development of HCC. To identify host factors that support the HBV life cycle, we previously established the HC1 cell line that maintains HBV infection and identified host genes required for HBV persistence. METHODS The present study focused on endothelial lipase (LIPG), which binds to heparan sulfate proteoglycans (HSPGs) in the cell membrane. RESULTS We found HBV infection was impaired in humanized liver chimeric mouse-derived hepatocytes that were transduced with lentivirus expressing short hairpin RNA against LIPG. Long-term suppression of LIPG combined with entecavir further suppressed HBV replication. LIPG was shown to be involved in HBV attachment to the cell surface by using 2 sodium taurocholate cotransporting peptide (NTCP)-expressing cell lines, and the direct interaction of LIPG and HBV large surface protein was revealed. Heparin and heparinase almost completely suppressed the LIPG-induced increase of HBV attachment, indicating that LIPG accelerated HBV attachment to HSPGs followed by HBV entry through NTCP. Surprisingly, the attachment of a fluorescently labeled NTCP-binding preS1 probe to NTCP-expressing cells was not impaired by heparin, suggesting the HSPG-independent attachment of the preS1 probe to NTCP. Interestingly, attachment of the preS1 probe was severely impaired in LIPG knockdown or knockout cells. Inhibitors of the lipase activity of LIPG similarly impaired the attachment of the preS1 probe to NTCP-expressing cells. CONCLUSIONS LIPG participates in HBV infection by upregulating HBV attachment to the cell membrane by means of 2 possible mechanisms: increasing HBV attachment to HSPGs or facilitating HSPG-dependent or HSPG-independent HBV attachment to NTCP by its lipase activity.

Abstract
Infection with hepatitis B virus (HBV) cannot be cured completely because of the persistence of covalently closed circular DNA (cccDNA). We previously found that the host gene dedicator of cytokinesis 11 (DOCK11) was required for HBV persistence. In this study, we further investigated the mechanism that links DOCK11 to other host genes in the regulation of cccDNA transcription. cccDNA levels were determined by quantitative real-time polymerase chain reaction (qPCR) and fluorescence in situ hybridization (FISH) in stable HBV-producing cell lines and HBV-infected PXB-cells®. Interactions between DOCK11 and other host genes were identified by super-resolution microscopy, immunoblotting, and chromatin immunoprecipitation. FISH facilitated the subcellular localization of key HBV nucleic acids. Interestingly, although DOCK11 partially colocalized with histone proteins, such as H3K4me3 and H3K27me3, and nonhistone proteins, such as RNA Pol II, it played limited roles in histone modification and RNA transcription. DOCK11 was functionally involved in regulating the subnuclear distribution of host factors and/or cccDNA, resulting in an increase in cccDNA closely located to H3K4me3 and RNA Pol II for activating cccDNA transcription. Thus, it was suggested that the association of cccDNA-bound Pol II and H3K4me3 required the assistance of DOCK11. DOCK11 facilitated the association of cccDNA with H3K4me3 and RNA Pol II.

Abstract
BACKGROUND & AIMS Hepatitis B virus (HBV) infection is difficult to cure owing to the persistence of covalently closed circular viral DNA (cccDNA). We performed single-cell transcriptome analysis of newly established HBV-positive and HBV-negative hepatocellular carcinoma cell lines and found that dedicator of cytokinesis 11 (DOCK11) was crucially involved in HBV persistence. However, the roles of DOCK11 in the HBV lifecycle have not been clarified. METHODS The cccDNA levels were measured by Southern blotting and real-time detection polymerase chain reaction in various hepatocytes including PXB cells by using an HBV-infected model. The retrograde trafficking route of HBV capsid was investigated by super-resolution microscopy, proximity ligation assay, and time-lapse analysis. The downstream molecules of DOCK11 and underlying mechanism were examined by liquid chromatography-tandem mass spectrometry, immunoblotting, and enzyme-linked immunosorbent assay. RESULTS The cccDNA levels were strongly increased by DOCK11 overexpression and repressed by DOCK11 suppression. Interestingly, DOCK11 functionally associated with retrograde trafficking proteins in the trans-Golgi network (TGN), Arf-GAP with GTPase domain, ankyrin repeat, and pleckstrin homology domain-containing protein 2 (AGAP2), and ADP-ribosylation factor 1 (ARF1), together with HBV capsid, to open an alternative retrograde trafficking route for HBV from early endosomes (EEs) to the TGN and then to the endoplasmic reticulum (ER), thereby avoiding lysosomal degradation. Clinically, DOCK11 levels in liver biopsies from patients with chronic hepatitis B were significantly reduced by entecavir treatment, and this reduction correlated with HBV surface antigen levels. CONCLUSIONS HBV uses a retrograde trafficking route via EEs-TGN-ER for infection that is facilitated by DOCK11 and serves to maintain cccDNA. Therefore, DOCK11 is a potential therapeutic target to prevent persistent HBV infection.

Abstract
HIV-2 infection will progress to AIDS in most patients without treatment, albeit at approximately half the rate of HIV-1 infection. HIV-2 capsid (p26) amino acid polymorphisms are associated with lower viral loads and enhanced processing of T cell epitopes, which may lead to protective Gag-specific T cell responses common in slower progressors. Lower virus evolutionary rates, and positive selection on conserved residues in HIV-2 env have been associated with slower progression to AIDS. In this study we analysed 369 heterochronous HIV-2 p26 sequences from 12 participants with a median age of 30 years at enrolment. CD4% change over time was used to stratify participants into relative faster and slower progressor groups. We analysed p26 sequence diversity evolution, measured site-specific selection pressures and evolutionary rates, and determined if these evolutionary parameters were associated with progression status. Faster progressors had lower CD4% and faster CD4% decline rates. Median pairwise sequence diversity was higher in faster progressors (5.7x10-3 versus 1.4x10-3 base substitutions per site, P<0.001). p26 evolved under negative selection in both groups (dN/dS=0.12). Median virus evolutionary rates were higher in faster than slower progressors - synonymous rates: 4.6x10-3 vs. 2.3x10-3; and nonsynonymous rates: 6.9x10-4 vs. 2.7x10-4 substitutions/site/year, respectively. Virus evolutionary rates correlated negatively with CD4% change rates (ρ = -0.8, P=0.02), but not CD4% level. The signature amino acid at p26 positions 6, 12 and 119 differed between faster (6A, 12I, 119A) and slower (6G, 12V, 119P) progressors. These amino acid positions clustered near to the TRIM5α/p26 hexamer interface surface. p26 evolutionary rates were associated with progression to AIDS and were mostly driven by synonymous substitutions. Nonsynonymous evolutionary rates were an order of magnitude lower than synonymous rates, with limited amino acid sequence evolution over time within hosts. These results indicate HIV-2 p26 may be an attractive therapeutic target.

Abstract
For the development of antiviral agents to eliminate hepatitis B virus (HBV), it is essential to establish an HBV cell culture system that can easily monitor HBV infection. Here, we created a novel HBV infection monitoring system using a luminescent 11-amino acid reporter, the high-affinity subunit of nano-luciferase binary technology (HiBiT). The HiBiT-coding sequence was inserted at the N-terminus of preS1 in a 1.2-fold plasmid encoding a genotype C HBV genome. After transfection of HepG2 cells with this HiBiT-containing plasmid, the supernatant was used to prepare a recombinant cell culture-derived virus (HiBiT-HBVcc). Primary human hepatocytes (PXB) were inoculated with HiBiT-HBVcc. Following inoculation, intracellular and extracellular HiBiT activity and the levels of various HBV markers were determined. Reinfection of naive PXB cells with HiBiT-HBVcc prepared from HiBiT-HBVcc-infected PXB cells was analyzed. When PXB cells were infected with HiBiT-HBVcc at several titers, extracellular HiBiT activity was detected in a viral titer-dependent manner and was correlated with intracellular HiBiT activity. Inhibitors of HBV entry or replication suppressed extracellular HiBiT activity. Viral DNA, RNA, and proteins were detectable, including covalently closed circular DNA, by Southern blot analysis. The synthesis of relaxed-circular DNA from single-stranded DNA in HiBiT-HBV decreased to one third of that of wild-type HBV, and the infectivity of HiBiT-HBVcc decreased to one tenth of that of wild-type HBVcc. HiBiT-HBVcc prepared from PXB cells harboring HiBiT-HBV was able to infect naive PXB cells. Conclusions: Recombinant HiBiT-HBV can undergo the entire viral life cycle, thus facilitating high-throughput screening for HBV infection in vitro using supernatants. This system will be a powerful tool for developing antiviral agents.

Abstract
Human hepatitis B virus (HBV) infection remains a serious health problem worldwide. However, the mechanism for the maintenance of HBV in a latent state within host cells remains unclear. Here, using single-cell RNA sequencing analysis, we identified four genes linked to the maintenance of HBV in a liver cell line expressing HBV RNA at a low frequency. These genes included DOCK11 and DENND2A, which encode small GTPase regulators. In primary human hepatocytes infected with HBV, knockdown of these two genes decreased the amount of both HBV DNA and covalently closed circular DNA to below the limit of detection. Our findings reveal a role for DOCK11 and DENND2A in the maintenance of HBV.

Abstract
The Lifshitz transition, a change in Fermi surface topology, is likely to greatly influence exotic correlated phenomena in solids, such as high-temperature superconductivity and complex magnetism. However, since the observation of Fermi surfaces is generally difficult in the strongly correlated systems, a direct link between the Lifshitz transition and quantum phenomena has been elusive so far. Here, we report a marked impact of the pressure-induced Lifshitz transition on thermoelectric performance for SnSe, a promising thermoelectric material without a strong electron correlation. By applying pressure up to 1.6 GPa, we have observed a large enhancement of the thermoelectric power factor by more than 100% over a wide temperature range (10-300 K). Furthermore, the high carrier mobility enables the detection of quantum oscillations of resistivity, revealing the emergence of new Fermi pockets at ∼0.86 GPa. The observed thermoelectric properties linked to the multivalley band structure are quantitatively reproduced by first-principles calculations, providing novel insight into designing the SnSe-related materials for potential valleytronic as well as thermoelectric applications.

Abstract
Endoscopic submucosal dissection (ESD) is a widely accepted procedure for superficial esophageal squamous cell carcinoma (SESCC) limited to the epithelium or lamina propria mucosae (EP/LPM). We aimed to compare the efficacy of endoscopic ultrasonography (EUS) and magnifying endoscopy with narrow band imaging (ME-NBI) for predicting the tumor invasion depth in patients with SESCC. Specifically, we evaluated the ability of these examinations to distinguish EP/LPM from SESCC invading the muscularis mucosae or superficial submucosa (MM/SM1) and more deeply invasive lesions before ESD.We retrospectively analyzed a database of all patients with SESCC who had undergone both EUS and ME-NBI for pretreatment staging and ESD resection at Hiroshima University Hospital between September 2007 and June 2015. The clinicopathologic characteristics of SESCCs were classified according to the Japanese Classification of Esophageal Cancer.A total of 174 lesions in 174 patients were included: 124 (71%) EP/LPMs, 35 (20%) MM/SM1s, and 15 (9%) SESCCs invading the mid submucosae (SM2). The sensitivity of EUS and of ME-NBI in distinguishing EP/LPM from MM/SM1 and more invasive lesions was 72% and 83%, respectively. The accuracy of EUS and ME-NBI in distinguishing EP/LPM from MM/SM1 and more invasive lesions was 70% and 82%, respectively. Sensitivity and accuracy of ME-NBI in distinguishing EP/LPM from MM/SM1 and more deeply invasive SESCCs is significantly higher than those of EUS (P = 0.048 and P = 0.017, respectively).ME-NBI may be more useful than EUS for the determination of SESCC invasion depth before ESD.

Abstract
BACKGROUND According to the Japanese Esophageal Society (JES) guidelines, risk factors for lymph node (LN) metastasis in the muscularis mucosa (MM)/submucosa to a depth of up to 200 μm (SM1) in cases of esophageal squamous cell carcinomas (ESCCs) include the presence of lymphatic invasion (ly), venous invasion (v), infiltration pattern (INF)c, and SM1. The long-term prognoses of these patients are unclear, and there are very few reports on the validation of the curative criteria for MM/SM1 ESCCs. AIMS To examine the long-term prognoses of these patients and the risk factors for LN metastasis of MM/SM1 ESCCs after endoscopic resection (ER). METHODS This study included patients with MM/SM1 ESCCs who underwent ER at Hiroshima University Hospital from December 1990 to November 2016. We evaluated the clinicopathological characteristics of 98 patients and overall survival, disease-specific survival, recurrence-free survival, and recurrence rates in the e-curative and non-e-curative groups. RESULTS The mean observation period was 75 months. There was no significant difference in disease-specific survival rate between the e-curative and non-e-curative groups (100 vs. 98%). There was no significant difference in disease-specific survival rates between the groups (100 vs. 98%). In contrast, the LN recurrence-free survival rate in patients with INFa, ly(-), and v(-) was significantly higher than that in patients with INFb/c, ly(+), or v(+) (100 and 87%, P < 0.05). CONCLUSION Contrary to the JES guidelines, our findings suggest that new criteria (MM/SM1, INFa, negative vertical margin (VM0), ly[-], and v[-]) may be associated with curative ER without additional treatment.

Abstract
SummaryThe objective of this study was to evaluate the effects of [D-Ala2, Nme-Phe4, Gly5-ol] enkephalin (DAMGO), a μ-opioid receptor agonist, and β-funaltrexamine (β-FNA), a μ-opioid receptor antagonist, on the biosynthetic capabilities of canine chondrocytes cultured in the presence of interleukin-1 β (IL-1 β). Articular chondrocytes were harvested from the humeral heads of three adult dogs and cultured in a three-dimensional (3-D) gel medium made from low-melting agarose and cell culture medium. Chondrocytes in 3-D culture were exposed to IL-1 β (0 or 20 ng/ml), DAMGO (0,0.1,1.0, or 10 μM), and β-FNA (0 or 10 μM) by addition to the liquid media in all possible combinations. On days five and 15 of 3-D culture, liquid medium samples were harvested for subsequent analysis of glycosaminogly- can (GAG), prostaglandin E2 (PGE2) and matrix metalloprotease-3 (MMP-3) content. On the same days, gel plugs were also harvested and evaluated for GAG content.Incubation with IL-1 β decreased the amount of GAG in the gel plugs and caused an increase in PGE2 production on days five and 15 of 3-D culture. Treatment with DAMGO or β-FNA did not significantly modulate PGE2 production, MMP-3 production, GAG loss to the medium or GAG content of the gel plugs on either day five or 15 of 3-D culture in the presence or absence of IL-1 β. We concluded that DAMGO and β-FNA had neither protective nor detrimental effects on the biosynthetic capabilities of chondrocytes in the presence or absence of IL-1 β.

Abstract
Sodium taurocholate cotransporting polypeptide (NTCP) was recently discovered as a hepatitis B virus (HBV) receptor, however, the detailed mechanism of HBV entry is not yet fully understood. We investigated the cellular entry pathway of HBV using recombinant HBV surface antigen L protein particles (bio-nanocapsules, BNCs). After the modification of L protein in BNCs with myristoyl group, myristoylated BNCs (Myr-BNCs) were found to bind to NTCP in vitro, and inhibit in vitro HBV infection competitively, suggesting that Myr-BNCs share NTCP-dependent infection machinery with HBV. Nevertheless, the cellular entry rates of Myr-BNCs and plasma-derived HBV surface antigen (HBsAg) particles were the same as those of BNCs in NTCP-overexpressing HepG2 cells. Moreover, the cellular entry of these particles was mainly driven by heparan sulfate proteoglycan-mediated endocytosis regardless of NTCP expression. Taken together, cell-surface NTCP may not be involved in the cellular uptake of HBV, while presumably intracellular NTCP plays a critical role.

Abstract
Cardiopulmonary bypass (CPB) contributes to a morbidity-inducing systemic Inflammatory response after cardiac surgery. We compared this response in patients receiving coronary artery bypass grafting (CABG) with (CPB group; n = 7) or without (off-pump group; n = 8) the Minimal Extracorporeal Circulation (MECC®) system. Serum concentrations of tumour necrosis factor (TNF)-α, soluble TNF receptors, pro- and anti-inflammatory interleukins (ILs) and other myocardial injury markers were measured after anaesthetic induction, at 1 h, 4 h and 24 h after completing all anastomoses or serially. Soluble TNF receptor type I (sTNFRI) and IL-8 peaked early after CABG in both groups and did not decline. Serum sTNFRI was significantly higher in the CPB compared with the off-pump group at 1 h, whereas IL-8 was significantly lower in the CPB group throughout. The MECC® system, therefore, produces an equivalent acute cytokine response and degree of myocardial injury to off-pump CABG, and may be useful when CABG cannot be performed without CPB.

Abstract
Iron-based compounds (IBS) display a surprising variety of superconducting properties that seems to arise from the strong sensitivity of these systems to tiny details of the lattice structure. In this respect, systems that become superconducting under pressure, like CaFe2As2, are of particular interest. Here we report on the first directional point-contact Andreev-reflection spectroscopy (PCARS) measurements on CaFe2As2 crystals under quasi-hydrostatic pressure, and on the interpretation of the results using a 3D model for Andreev reflection combined with ab-initio calculations of the Fermi surface (within the density functional theory) and of the order parameter symmetry (within a random-phase-approximation approach in a ten-orbital model). The almost perfect agreement between PCARS results at different pressures and theoretical predictions highlights the intimate connection between the changes in the lattice structure, a topological transition in the holelike Fermi surface sheet, and the emergence on the same sheet of an order parameter with a horizontal node line.

Abstract
BACKGROUND A variety of presumed hereditary, neurologic diseases have been reported in young Rottweilers. Overlapping ages of onset and clinical signs have made antemortem diagnosis difficult. One of these diseases, neuronal vacuolation and spinocerebellar degeneration (NVSD) shares clinical and histological features with polyneuropathy with ocular abnormalities and neuronal vacuolation (POANV), a recently described hereditary disease in Black Russian Terriers (BRTs). Dogs with POANV harbor mutations in RAB3GAP1 which codes for a protein involved in membrane trafficking. HYPOTHESIS Rottweilers with NVSD will be homozygous for the RAB3GAP1:c.743delC allele associated with POANV in BRTs. ANIMALS Eight Rottweilers with NVSD confirmed at necropsy, 128 Rottweilers without early onset neurologic signs, and 468 randomly selected dogs from 169 other breeds. METHODS Retrospective case-control study. Dogs were genotyped for the RAB3GAP1:c.743delC allele with an allelic discrimination assay. RESULTS All 8 NVSD-affected dogs were homozygous for the RAB3GAP1:c.743delC allele while the 128 NVSD-free Rottweilers were either homozygous for the reference allele (n = 105) or heterozygous (n = 23) and the 468 genotyped dogs from other breeds were all homozygous for the reference allele. CONCLUSIONS AND CLINICAL IMPORTANCE The RAB3GAP1:c.743delC mutation is associated with a similar phenotype in Rottweilers and BRTs. Identification of the mutation permits a DNA test that can aid in the diagnosis of NVSD and identify carriers of the trait so that breeders can avoid producing affected dogs. Disruption of membrane trafficking could explain the neuronal vacuolation seen in NVSD and other spongiform encephalopathies.

Abstract
The aim of this study was to develop a novel in vivo corneal model of fibrosis in dogs utilizing alkali burn and determine the ability of suberanilohydroxamic acid (SAHA) to inhibit corneal fibrosis using this large animal model. To accomplish this, we used seven research Beagle dogs. An axial corneal alkali burn in dogs was created using 1 N NaOH topically. Six dogs were randomly and equally assigned into 2 groups: A) vehicle (DMSO, 2 μL/mL); B) anti-fibrotic treatment (50 μM SAHA). The degree of corneal opacity, ocular health, and anti-fibrotic effects of SAHA were determined utilizing the Fantes grading scale, modified McDonald-Shadduck (mMS) scoring system, optical coherence tomography (OCT), corneal histopathology, immunohistochemistry (IHC), and transmission electron microscopy (TEM). The used alkali burn dose to produce corneal fibrosis was well tolerated as no significant difference in mMS scores between control and treatment groups (p = 0.89) were detected. The corneas of alkali burned dogs showed significantly greater levels of α-smooth muscle actin, the fibrotic marker, than the controls (p = 0.018). Total corneal thickness of all dogs post-burn was significantly greater than baseline OCT images irrespective of treatment (p = 0.004); TEM showed that alkali burned corneas had significantly greater minimum and maximum interfibrillar distances than the controls (p = 0.026, p = 0.018). The tested topical corneal alkali burn dose generated significant opacity and fibrosis in dog corneas without damaging the limbus as evidenced by histopathology, IHC, TEM, and OCT findings, and represents a viable large animal corneal fibrosis in vivo model. Additional in vivo SAHA dosing studies with larger sample size are warranted.

Abstract
Multiple organ dysfunction syndrome (MODS), defined as the presence of altered organ function in an acutely ill patient such that homeostasis cannot be maintained without intervention, is a cause of high morbidity and mortality in humans and animals. Many advances have been made in understanding the pathophysiology and treatment of this syndrome in human medicine, but much still is unknown. This comparative review will provide information regarding the history and pathophysiology of MODS in humans and discuss how MODS affects each major organ system in animals.

Abstract
We investigated the incidence of anomalies in the vertebral arteries and Circle of Willis with three-dimensional CT angiography in 55 consecutive patients who had undergone an instrumented posterior fusion of the cervical spine. We recorded any peri-operative and post-operative complications. The frequency of congenital anomalies was 30.9%, abnormal vertebral artery blood flow was 58.2% and vertebral artery dominance 40%. The posterior communicating artery was occluded on one side in 41.8% of patients and bilaterally in 38.2%. Variations in the vertebral arteries and Circle of Willis were not significantly related to the presence or absence of posterior communicating arteries. Importantly, 18.2% of patients showed characteristic variations in the Circle of Willis with unilateral vertebral artery stenosis or a dominant vertebral artery, indicating that injury may cause lethal complications. One patient had post-operative cerebellar symptoms due to intra-operative injury of the vertebral artery, and one underwent a different surgical procedure because of insufficient collateral circulation. Pre-operative assessment of the vertebral arteries and Circle of Willis is essential if a posterior spinal fusion with instrumentation is to be carried out safely.

Abstract
Cartilage repair in terms of replacement, or
regeneration of damaged or diseased articular cartilage with functional tissue,
is the ‘holy grail’ of joint surgery. A wide spectrum of strategies
for cartilage repair currently exists and several of these techniques
have been reported to be associated with successful clinical outcomes
for appropriately selected indications. However, based on respective
advantages, disadvantages, and limitations, no single strategy, or
even combination of strategies, provides surgeons with viable options
for attaining successful long-term outcomes in the majority of patients.
As such, development of novel techniques and optimisation of current techniques
need to be, and are, the focus of a great deal of research from
the basic science level to clinical trials. Translational research
that bridges scientific discoveries to clinical application involves
the use of animal models in order to assess safety and efficacy
for regulatory approval for human use. This review article provides
an overview of animal models for cartilage repair. Cite this article: Bone Joint Res 2014;4:89–94.

Abstract
OBJECTIVES The objective of this study was to determine the optimal scan delay quantitatively and qualitatively in cerebral CT angiography (CTA) with a test injection method at the circle of Willis (cW). METHODS 66 consecutive patients suspected of having unruptured intracranial aneurysms underwent CTA using 40 ml of 370 mg iodine ml(-1) contrast material (CM). After the time until CM arrival at the cW (T(cW)) was calculated, scan delay was divided into three groups according to T(cW) and scan duration (SD) between the second cervical vertebra and cW as follows: [(T(cW)+6)-SD] in 21 patients (Group A); [(T(cW)+8)-SD] in 23 patients (Group B); and [(T(cW)+10)-SD] in 22 patients (Group C). Arterial and venous attenuation in the intracranial vessels was measured. Mean attenuation values were compared quantitatively. The arterial enhancement and venous overlap at the cW and above the cW were qualitatively compared among the three groups. RESULTS Mean arterial attenuation in Groups B and C was significantly higher than that in Group A. Mean venous attenuation in Group C was significantly higher than those in Groups A and B. Arterial enhancement above the cW showed a significant difference between Groups A and C, and at the cW between Groups A and B, and Groups A and C. There was a significant difference in venous overlap among the three groups, except for that at the cW between Groups B and C. CONCLUSIONS Setting scan delay as [(T(cW)+8)-SD] s can produce the best performance both quantitatively and qualitatively.

Abstract
Physical activity has been shown to enhance endothelial function of central and peripheral vascular beds. The primary purpose of the present study was to test the hypothesis that a short-term exercise training program would result in enhanced endothelium-dependent vasorelaxation of a major artery supplying blood flow to the knee joint, the middle genicular artery. Female Yucatan miniature swine were randomly assigned into exercise trained (n=7) or sedentary (n=7) groups. Exercise trained pigs underwent a daily exercise training program on treadmills for 7 days. In vitro assessment of vasorelaxation was determined in a dose response manner by administrating increasing doses of 3 different dilators; adenosine diphosphate, bradykinin, and sodium nitroprusside. The role of nitric oxide synthase and cyclooxygenase pathways in vasomotor responses was evaluated with specific inhibitors using nitro-L-arginine methyl ester and indomethacin incubation, respectively. The results of this investigation indicate that adenosine and bradykinin-induced endothelium-dependent vasorelaxation were significantly enhanced in middle genicular artery from exercise trained pigs (p<0.05). Endothelium-independent vasorelaxation was not altered with exercise training as determined by the response to sodium nitroprusside. The findings of the present investigation indicate that short-term exercise training enhances endothelial function of middle genicular artery through adaptations in the nitric oxide synthase and by non-nitric oxide synthase, non-cyclooxygenase pathways.

Abstract
OBJECTIVE To test the hypothesis that changes in subchondral bone are significantly different among three canine models of osteoarthritis (OA). DESIGN In 21 purpose-bred mongrel dogs, OA was induced in one knee joint via either anterior cruciate ligament transection (ACLt; n = 5), medial femoral condylar groove creation (GR; n = 6), or medial meniscal release (MR; n = 5). Five dogs that had sham surgery (SH; n = 5) in one knee joint served as controls. Lameness scoring was performed every 4 weeks. Twelve weeks after surgery, the knee joints were examined by histology and histomorphometry. RESULTS Articular cartilage pathology as determined by Mankin scores was significantly severe in all three OA models compared to SH controls in the medial tibia (P < 0.001 to P = 0.026). ACLt had significantly thinner subchondral plate thickness (Sp.Th) in both the medial and lateral tibias while MR had significantly thicker Sp.Th in the medial tibia compared to SH controls (P < 0.001 to P = 0.011). Trabecular bone volume (BV/TV) and trabecular bone thickness (Tb.Th) for ACLt were significantly less than SH controls in the tibias (P < 0.001 to P = 0.011). Tibial Sp.Th, BV/TV, and Tb.Th were all moderately to strongly correlated with lameness scores obtained throughout the study period (r = -0.436 to r = -0.738, P < 0.001 to P = 0.047) while Mankin scores showed moderate to strong correlations with Sp.Th in each OA model (r = 0.465 to r = 0.816, P < 0.001 to P = 0.033). CONCLUSIONS Changes in Sp.Th are associated with articular cartilage damage while tibial Sp.Th and BV/TV and Tb.Th appear to be all influenced by joint loading alterations.

Abstract
A neutron scattering study of heavily hole-overdoped superconducting KFe2As2 revealed a well-defined low-energy incommensurate spin fluctuation at [π(1 ± 2 δ),0] with δ = 0.16. The incommensurate structure differs from the previously observed commensurate peaks in electron-doped AFe2As2 (A = Ba, Ca, or Sr) at low energies. The direction of the peak splitting is perpendicular to that observed in Fe(Te,Se) or in Ba(Fe,Co)2As2 at high energies. A band structure calculation suggests interband scattering between bands around the Γ and X points as an origin of this incommensurate peak. The perpendicular direction of the peak splitting can be understood within the framework of multiorbital band structure. The results suggest that spin fluctuation is more robust in hole-doped than in electron-doped samples, which can be responsible for the appearance of superconductivity in the heavily hole-doped samples.

Abstract
The dog is a common model for study of osteoarthritis (OA). Subjective histologic scoring systems have often served as the reference standard for presence and severity of OA. However, these scoring systems have perceived shortcomings. The system developed for this report attempts to address these shortcomings by providing a standardized methodology for global assessment of the joint, versatility and the potential for relative weighting of pathology, allowing for comparison among time points, studies, and centers, and critical analysis of the system's reliability. The proposed system for assessment of canine tissues appears to provide an effective method for global assessment of articular pathology in OA. The system is versatile, comprehensive, and reliable and appears to have advantages over conventional scoring systems.

Abstract
An 8-year-old castrated male mixed-breed dog had an ill-defined hemorrhagic and painful lesion in the base of the claw of the second digit of the right forelimb. Radiographically, the expansile and lytic lesion affected the distal phalanx. The digit was amputated and submitted for histologic examination. Histologically, the distal phalanx was largely replaced by a mass composed of variably sized cavernous vascular spaces lined by a single layer of flattened endothelial cells. A similar mass was in the subcutis adjacent to the distal phalanx. The benign vascular proliferation involving the medulla of bone and a second tissue type in this dog is consistent with skeletal-extraskeletal angiomatosis as described in humans. To the authors' knowledge, this is the first report of skeletal-extraskeletal angiomatosis in the veterinary literature.

Abstract
We report an unusual clinical presentation of ruptured proximal aorta as a left hemothorax after operation for type A dissection. A 74-year-old man who had undergone ascending aortic replacement for acute type A dissection 4 months previously developed a loss of consciousness followed by shock state. Both chest X-ray and computed tomography (CT) scan revealed opacified left hemothorax. The patient died during a diagnostic procedure. Post mortem examination showed rupture of proximal aortic dissection extended to the left pleural cavity path through the right atrial wall and the right ventricular wall.

Abstract
AIMS Despite the growing literature on workplace tobacco control policies, very few studies have evaluated the role of smoking cessation programme as one of these policies in a university setting. We aimed to investigate the efficacy of intensive cessation programme delivered in a group format using nicotine patch therapy and internet mailing supports for our university employees. METHODS From January 2003, we conducted the group therapy programme for smoking cession seven times in Okayama University, Japan. This programme consisted of nicotine patch therapy and on-line supporting system. Smoking status was regularly assessed by direct interviews. RESULTS A total of 102 employees were enrolled in this programme, of whom 101 initiated their smoking cessation. One hundred participants (99%) received nicotine patch therapy, and its toxicities were generally mild. Of the 94 employees who could be follow-up for a year after the cessation, 50 (53%) sustained abstinence for a year. Multivariate analysis revealed that writing and sending e-mail messages within the first 1 week were significant factors affecting long-term cessation. The type of position also affected the cessation rate. CONCLUSION This study suggests that our programme in a university setting seems to be effective mainly because of peer-supports among the participants through regular face-to-face meetings and their own mailing supports.

Abstract
By means of a combination of the local density approximation and dynamical mean field theory (LDA + DMFT), we study the possibility of making a d(1) analogue of d(9) cuprates on the basis of Sr(2)VO(4). We calculate the electronic structure of Sr(2)VO(4) under pressure, and show that while the material is a 1/6-filled three-band system at ambient pressure with a small level splitting between the d(xy)- and d(yz/zx)-bands, an orbital polarization occurs under sufficiently high uniaxial pressure in the c-direction. While all energy scales are relatively small, the electronic structure of Sr(2)VO(4) under pressure is similar to that of La(2)CuO(4); it is a two-dimensional half-filled single-band system which has, relative to the nearest neighbour hopping, a similar Coulomb repulsion and next-nearest neighbour hopping. We also study the effect of substituting Sr by Ba, i.e., chemical pressure, and show that the pressure needed for the orbital polarization is considerably reduced.

Abstract
This Letter theoretically discusses quasiparticle states and nuclear spin relaxation rates T1-1 in the quasi-one-dimensional superconductor (TMTSF)2PF6 under a magnetic field applied parallel to the conduction chains. We study the effects of Josephson-type vortices on T1(-1) by solving the Bogoliubov-de Gennes equation for p-, d- or f-wave pairing interactions. In the presence of line nodes in pairing functions, T1(-1) is proportional to T in sufficiently low temperatures because quasiparticles induced by vortices at the Fermi energy relax spins. We also try to identify the pairing symmetry of (TMTSF)2PF6.

Abstract
Two alpha-type CK2-activated PKAs (CK2-aPKAIalpha and CK2-aPKAIIalpha) were biochemically characterized in vitro using GST-HBV core fusion protein (GST-Hcore) and GST-Hcore157B as phosphate acceptors. It was found that (i), in the absence of cAMP, these two CK2-aPKAs phosphorylated both Ser-170 and Ser-178 on GST-Hcore and Hcore157B; (ii) this phosphorylation was approx. 4-fold higher than their phosphorylation by cAMP-activated PKAs; and (iii) suramin effectively inhibited the phosphorylation of Hcore157B by CK2-aPKAIIalpha through its direct binding to Hcore157B in vitro. These results suggest that high phosphorylation of HBV-CP by two CK2-aPKAs, in the absence of cAMP, may be involved in the pregenomic RNA (pgRNA) encapsidation and DNA-replication in HBV-infected cells.

Abstract
The inhibitory effect of suramin on the phosphorylation of GST-HBV core fusion protein (GST-Hcore) and two GST-Hcore fusion polypeptides (Hcore157B and Hcore164B) by two alpha-type cAMP-dependent protein kinases (PKAIalpha and PKAIIalpha) was biochemically investigated in vitro. It was found that (i) this phosphorylation was inhibited by suramin at a low concentration (IC(50)=approx. 10 nM); (ii) a relative high dose of suramin was required to inhibit an autophosphorylation of PKAIIalpha (IC(50)=approx. 0.7 muM) and the PKAIIalpha-mediated phosphorylation of histone H2B (IC(50)=approx. 0.4 muM); (iii) the PKAIIalpha-mediated phosphorylation of Hcore157B was more sensitive to suramin than the phosphorylation of Hcore157B by Ca(2+)-dependent protein kinase (PKC); and (iv) suramin had a high binding affinity for Hcore157B, but not for histone H2B in vitro. These results suggest that suramin selectively inhibits the PKA-mediated phosphorylation of HBV-CP through the direct binding in vitro of suramin to the Arg-rich C-terminal region (containing three potential phosphorylation sites for PKA) on HBV-CP.
