Abstract
BACKGROUND Implant removal due to infection is one of the major causes failure following open reduction and internal fixation (ORIF). The aim of this study was to determine trends and predictors of infection-related implant removal following ORIF of extremities using a nationally representative database. METHODS Nationwide Inpatient Sample data from 2006 to 2017 was used to identify cases of ORIF following upper and lower extremity fractures, as well as cases that underwent infection-related implant removal following ORIF. Multivariate analysis was performed to identify independent predictors of infection-related implant removal, controlling for patient demographics and comorbidities, hospital characteristics, site of fracture, and year. RESULTS For all ORIF procedures, the highest rate of implant removal due to infection was the phalanges/hand (5.61%), phalanges/foot (5.08%), and the radius/ulna (4.85%). Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Tarsal/metatarsal fractures (odds ratio (OR)=1.45, 95% confidence interval (CI): 1.02-2.05), and tibial fractures (OR=1.82, 95% CI: 1.45-2.28) were identified as independent predictors of infection-related implant removal. Male gender (OR=1.67, 95% CI: 1.49-1.87), Obesity (OR=1.85, 95% CI: 1.34-2.54), diabetes mellitus with chronic complications (OR=1.69, 95% CI: 1.13-2.54, P<0.05), deficiency anemia (OR=1.59, 95% CI: 1.14-2.22) were patient factors that were associated with increased infection-related removals. Removal of implant due to infection had a higher total charge associated with the episode of care (mean: $166,041) than non-infection related implant removal (mean: $133,110). CONCLUSION Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Diabetes, liver disease, and rheumatoid arthritis were important predictors of infection-related implant removal. The study identified some risk factors for implant related infection following ORIF, such as diabetes, obesity, and anemia, that should be studied further to implement strategies to reduce rate of infection following ORIF.

Abstract
CASES Long-bone fractures in patients with Klippel-Trénaunay syndrome (KTS), a rare disorder of the venous, lymphatic, and capillary system, are difficult to treat with many complications. Two patients diagnosed with KTS presented with closed femoral shaft fractures after low-energy falls. Conservative treatment, open reduction internal fixation, and intramedullary nailing resulted in painful nonunions. Ultimately, both patients achieved pain relief and the ability to ambulate after en bloc resection and reconstruction. CONCLUSIONS These cases demonstrate the challenges in achieving bony union when treating long-bone fractures in KTS. The feasibility of undergoing extensive resection and reconstruction to regain function is best approached with a multidisciplinary team.

Abstract
Arthroscopic reduction of tibial plateau fractures have been gaining in popularity. Advantages include accurate diagnosis and treatment of joint pathology, minimally invasive soft tissue dissection, quicker recovery of joint motion, and anatomic reduction of joint surface. Success depends on accurate fracture selection. With arthroscopic-assisted reduction of tibial plateau fractures, patient set-up is similar to standard knee arthroscopy, but the C-arm is used to aid with fracture reduction and fixation. Outcomes are comparable or even improved when compared with standard procedures, and morbidity with arthroscopic reduction can often be lower with decreased rates of infection, wound complications, and thromboembolism.

Abstract
One of the main objectives of the ANTARES telescope is the search for point-like neutrino sources. Both the pointing accuracy and the angular resolution of the detector are important in this context and a reliable way to evaluate this performance is needed. In order to measure the pointing accuracy of the detector, one possibility is to study the shadow of the Moon, i.e. the deficit of the atmospheric muon flux from the direction of the Moon induced by the absorption of cosmic rays. Analysing the data taken between 2007 and 2016, the Moon shadow is observed with 3.5 σ statistical significance. The detector angular resolution for downward-going muons is 0 . 73 ∘ ± 0 . 14 ∘ . The resulting pointing performance is consistent with the expectations. An independent check of the telescope pointing accuracy is realised with the data collected by a shower array detector onboard of a ship temporarily moving around the ANTARES location.

Abstract
A novel algorithm to reconstruct neutrino-induced particle showers within the ANTARES neutrino telescope is presented. The method achieves a median angular resolution of [Formula: see text] for shower energies below 100 TeV. Applying this algorithm to 6 years of data taken with the ANTARES detector, 8 events with reconstructed shower energies above 10 TeV are observed. This is consistent with the expectation of about 5 events from atmospheric backgrounds, but also compatible with diffuse astrophysical flux measurements by the IceCube collaboration, from which 2-4 additional events are expected. A [Formula: see text] C.L. upper limit on the diffuse astrophysical neutrino flux with a value per neutrino flavour of [Formula: see text] is set, applicable to the energy range from 23 TeV to 7.8 PeV, assuming an unbroken [Formula: see text] spectrum and neutrino flavour equipartition at Earth.

Abstract
Despite dedicated research has been carried out to adequately map the distribution of the sperm whale in the Mediterranean Sea, unlike other regions of the world, the species population status is still presently uncertain. The analysis of two years of continuous acoustic data provided by the ANTARES neutrino telescope revealed the year-round presence of sperm whales in the Ligurian Sea, probably associated with the availability of cephalopods in the region. The presence of the Ligurian Sea sperm whales was demonstrated through the real-time analysis of audio data streamed from a cabled-to-shore deep-sea observatory that allowed the hourly tracking of their long-range echolocation behaviour on the Internet. Interestingly, the same acoustic analysis indicated that the occurrence of surface shipping noise would apparently not condition the foraging behaviour of the sperm whale in the area, since shipping noise was almost always present when sperm whales were acoustically detected. The continuous presence of the sperm whale in the region confirms the ecological value of the Ligurian sea and the importance of ANTARES to help monitoring its ecosystems.

Abstract
OBJECTIVE To evaluate the need for postnatal neurosurgical intervention after fetoscopic patch coverage of spina bifida aperta (SBA). METHODS This was a retrospective analysis of a cohort of 71 fetuses which underwent minimally invasive fetoscopic patch coverage of SBA between 21 + 0 and 29 + 1 weeks of gestation. Postnatal neurosurgical procedures were classified into two types: re-coverage of the SBA within the first 3 months following birth, and shunt placement as treatment of associated hydrocephalus within the first year. RESULTS Location of the SBA was lumbosacral in 59 cases, lumbar in seven, thoracic in three and sacral in two. In total, 20/71 (28%) patients underwent early postnatal neurosurgical intervention by means of re-coverage of the SBA. This was performed because of cerebrospinal fluid leakage in seven (35%), adhesions with functional deterioration in three (15%), incomplete coverage in five (25%) and skin defect in five (25%) cases. Ventriculoperitoneal shunt placement within 1 year was required in 32 (45%) cases and was preceded by ventriculostomy in two. Three (4%) infants needed Chiari decompression surgery in the first 12 months following birth, because of syringomyelia or gait disturbance. CONCLUSIONS Fetoscopic patch coverage of SBA may require postnatal re-coverage in some cases. In most cases, conservative wound treatment shows good results, without requiring neurosurgical intervention. The low 1-year-shunt rate is comparable to data of the Management of Myelomeningocele Study and lower compared with published data of patients with postnatal only coverage of SBA.

Abstract
BACKGROUND Research applying psychological behaviour change theories to hand hygiene compliance is scarce, especially for physicians. AIM To identify psychosocial determinants of self-reported hand hygiene behaviour (HHB) of physicians and nurses in intensive care units (ICUs). METHODS A cross-sectional survey using a self-administered questionnaire that applied concepts from the Health Action Process Approach on hygienic hand disinfection was conducted in 10 ICUs and two haematopoietic stem cell transplantation units at Hannover Medical School, Germany. Self-reported compliance was operationalized as always disinfecting one's hands when given tasks associated with risk of infection. Using seven-point Likert scales, behavioural planning, maintenance self-efficacy and action control were assessed as psychological factors, and personnel and material resources, organizational problems and cooperation on the ward were assessed as perceived environmental factors. Multiple logistic regression analysis was employed. FINDINGS In total, 307 physicians and 348 nurses participated in this study (response rates 70.9% and 63.4%, respectively). Self-reported compliance did not differ between the groups (72.4% vs 69.4%, P = 0.405). While nurses reported stronger planning, self-efficacy and action control, physicians indicated better personnel resources and cooperation on the ward (P < 0.02). Self-efficacy [odds ratio (OR) 1.4, P = 0.041], action control (OR 1.8, P < 0.001) and cooperation on the ward (OR 1.5, P = 0.036) were positively associated with HHB among physicians, but only action control was positively associated with HHB among nurses (OR 1.6, P < 0.001). CONCLUSION The associations between action control (self-regulatory strategies where behaviour is evaluated continuously and automatically against guidelines) and compliance indicate that HHB is a habit in need of self-monitoring. The fact that perceived cooperation on the ward was the only environmental correlate of HHB among physicians stresses the importance of team-directed interventions.

Abstract
AIM The extracellular matrix protein ED-B fibronectin (ED-B) is upregulated in inflammatory atherosclerotic lesions. However, functional in vivo imaging of ED-B-containing plaques has not been explored. This study evaluated whether [(99m)Tc]-conjugated AP39 ([(99m)Tc]-AP39), a single-chain antibody specific to ED-B, can be used for in vivo detection of atherosclerotic plaques in Western diet (WD)-fed, apolipoprotein E-deficient (apoE-/-) mice as compared to wildtype (WT) control mice. METHODS Using SPECT, 12-month-old WD-fed apoE-/- and WT mice were studied 4 hours after injecting [(99m)Tc]-AP39 (148 MBq). Subsequently, mice were sacrificed, thoracic aortas measured in a g-counter, and plaques analyzed using histology, immuno-histochemistry, autoradiography, and morphometry. RESULTS In vivo [(99m)Tc]-AP39-SPECT imaging of apoE-/- mice demonstrated a significant signal activity in the plaque-ridden thoracic aorta (52.236 ± 40.646 cpm/cm³) that co-localized with the aortic arch and the supra-aortic arteries in MRI scans. Low signal activity (9.468 ± 4.976 cpm/cm³) was observed in WT mice. In apoE-/- mice, the strongest signals were detected in the aortic root, aortic arch and along the abdominal aorta. Autoradiography analysis of aortas from apoE-/- mice confirmed the in vivo observation by demonstrating signal localization in atherosclerotic plaques. The size of autoradiography-positive plaque areas correlated significantly with the size of ED-B-positive (r=0.645, P=0.044) or macrophage-infiltrated (r=0.84, P<0.002) plaques. A significant correlation was found between the sizes of ED-B-positive and macrophage-infiltrated plaque areas (r=0.93, P<0.01). CONCLUSION [(99m)Tc]-AP39-SPECT in vivo imaging detects inflammatory plaque lesions in WD-fed apoE-/- mice.

Abstract
BACKGROUND AND AIM Hand hygiene practice is one of the most effective measures to prevent healthcare-associated infections. This study examines the trends of hand hygiene compliance among physicians and nurses on the intensive care units (ICU) and hematopoetic stem cell transplantation units (HSCTU) at Hannover Medical School. An observational study via repeated cross-sectional assessments was conducted during the first 6 years of the "AKTION Saubere Hände" (ASH), i.e. the German adaptation of WHO's "Clean Care is Safer Care" campaign. METHODS Compliance rates were directly observed in accordance with WHO definitions on the 10 ICU and two HSCTU. Overall, 13,175 hand hygiene opportunities were observed between 2008 and 2013. RESULTS In 2008, compliance rates of physicians and nurses did not differ significantly in statistical terms (53% vs. 57%, p=0.085). Physicians' compliance improved to 64% in 2011, but declined again to 48.4% in 2013 (p < 0.001). In contrast, hand hygiene compliance among nurses had increased to 71.3% as soon as 2009 /10 (p < 0.001). Their compliance dropped to 55.8% in 2013 and thus to baseline level (p=0.444), while remaining higher than that of physicians (p=0.003). Similar trends pertained to the surgical ICU. CONCLUSIONS These results indicate that during the ASH-campaign hand hygiene compliance increased initially both among physicians and nurses, albeit so far not in a sustainable fashion. This implies an increased demand for interventions which not only promote motivation, but also its translation into stable and sustained behavior in accordance with guidelines.

Abstract
With increasing recognition of the complications related to coagulopathies, it is of paramount importance for all orthopedic surgeons to possess a basic knowledge of common bleeding disorders. The evaluation of the coagulopathic patient requires a careful history, physical examination, and laboratory evaluation. Bleeding disorders commonly include quantitative and qualitative platelet and coagulation factor disorders and coagulation inhibitors. The management of these coagulopathies that can be encountered in elective and nonelective practice is often ignored. With appropriate knowledge and a multidisciplinary approach with hematologists and cardiologists, surgeons can perform minor and major orthopedic procedures safely and effectively.

Abstract
AIMS To evaluate the potential contribution of maternal glucose and lipids to fetal metabolic variables and growth in pregnancies with normal glucose tolerance in comparison with pregnancies with well-controlled gestational diabetes previously reported by us. METHODS In 190 pregnancies with normal oral glucose tolerance tests (controls), insulin, glucose and lipid components were determined in maternal and arterial cord blood serum. Birthweight and neonatal fat mass were obtained after delivery. Values were adjusted for maternal pre-pregnancy BMI, Caesarean section and gestational age. Measurements were compared with those of gestational diabetes previously reported. RESULTS Maternal serum glucose, triacylglycerol, free fatty acid and cholesterol levels did not differ between control pregnancies and those with gestational diabetes, whereas insulin, homeostasis model assessment and glycerol values were significantly lower in the former (2.6 vs. 5.6 μmol/l and 176 vs. 193 μmol/l, respectively). In contrast, cord blood glucose and free fatty acids were significantly lower in control pregnancies than in those with gestational diabetes (3.9 vs. 4.4 mmol/l and 80.7 vs. 137 μmol/l, respectively); the same was valid for insulin (0.03 vs. 0.05 nmol/l) and homeostasis model assessment (1.0 vs. 1.87). In control pregnancies, maternal serum glucose, free fatty acids and glycerol correlated with those in cord blood, but not with neonatal weight and fat mass, as seen for free fatty acids in those with gestational diabetes. The negative correlation between cord blood triacylglycerols and neonatal weight or fat mass previously reported in gestational diabetes could not be confirmed in control pregnancies, where all fetal lipids showed a positive correlation to neonatal anthropometrics. CONCLUSION In normal pregnancies, in contrast to those with gestational diabetes, maternal lipids do not influence neonatal weight. Similar levels of maternal lipids in pregnancies with gestational diabetes and control pregnancies, but higher free fatty acids in the cord blood of those with gestational diabetes, indicate their enhanced placental transport and/or enhanced lipolysis as a result of decreased fetal insulin responsiveness.

Abstract
Modern military medicine is an ever advancing field, capable of remarkable feats. We present the case of a 16-year-old Iraqi female with a single gunshot wound to the pelvis with extensive rectal injury who survived despite the odds. Using "damage control" techniques, this patient survived despite a reported 30% mortality associated with such wounds. During the course of her stay, she was cared for by a multidisciplinary team whose integrated efforts led to survival and complete closure of 2 of 3 wounds prior to discharge. The case demonstrates the success of modern military medical measures applied to a malnourished pediatric civilian in an austere environment. In addition to being noteworthy as an extraordinary case of survival, this case raises questions about the implications of practicing short-term modern medicine on a population that will have to be reintegrated into a primitive medical establishment, possibly before definitive care is complete.

Abstract
BACKGROUND Hand disinfection is a well-known and appropriate practise for infection prevention. Hence, it is logical to encourage its compliance and to provide its sustainability in the daily routine of a hospital. Several campaigns address an improvement of this important prevention measure. METHODS In the Hannover Medical School the health staffs on the intensive care units and bone marrow transplantation wards were examined for this topic by a standardised questionnaire. The aim was to detect deficiencies and the level of knowledge. RESULTS The forms were handed out to 838 health-care workers on 12 wards. 346 (41.2 %) were analysed. Inadequate hand disinfection due to a lack of time was the most common answer (43.1 %), followed by "there is no reason" (37.3 %). The alcoholic hand rub should be better available (50.3 %) and a continuing education programme should be provided (42.8 %) for improving hand hygiene practise. CONCLUSION The survey revealed the known risk factors for non-compliance. At this point, the national hand campaign "Aktion Saubere Hände" supports training courses by providing instruction materials for all participants. These materials are used for training health-care workers individually.

Abstract
Critical illness polyneuropathy (CIP) occurs in association with sepsis and multiple organ failure; however, little is known about the pathomechanisms of CIP and its therapy. In order to determine the parameters which interfere with development of CIP, electrophysiological investigations of peripheral nerves and biochemical measures were correlated to each other. The present study includes 20 consecutive patients in an intensive care unit developing severe sepsis or septic shock. Nerve conduction studies and electromyography were performed with occurring sepsis (day 1, 7, 14) and neurophysiological parameters were correlated with biochemical measures, especially indicators of infection and inflammation. It was found that all patients developed neurophysiological signs of axonal motor polyneuropathy. There was a significant correlation between serum concentrations of endotoxin and interleukin-2 receptors (IL2-R) and reduction of the amplitude of the compound motor action potentials. Other clinical and biochemical parameters showed no significant correlations with neurophysiological data. This finding apparently indicates that endotoxin damages nerve axons directly or indirectly, e.g. by activation of inflammatory cascades (IL2-R). Endotoxin appears to be an essential factor in the pathogenesis of CIP in sepsis, and therapeutic options neutralizing endotoxin may prevent development of CIP.

Abstract
We study how a local air plasma treatment affects the mechanical properties of polystyrene by performing indentation measurements on the polymer in the elastic and plastic regime. The local exposure to plasma was obtained by placing a shadow-mask with quadratic holes of 45 x 45 microm(2) on top of the polymer substrate, providing uncovered (exposed to the plasma) and covered (protected from the plasma) areas. We have analyzed quantitatively the topography and the elastic-plastic properties of such a sample with atomic force microscopy (AFM) measurements, both before and after plasma treatment. To enhance the differences between covered and uncovered areas, the sample has been exposed to solvent vapor. This generates regions which are differently swollen. The quantitative investigation of the mechanical properties of the swollen sample for different solvent exposure times gives further insight into the changes of polystyrene mechanical properties caused by the plasma.

Abstract
This in vitro study evaluated the effect of metal alloys on three-body wear resistance of enamel and dentin, and vice versa. Three-body wear of human enamel, dentin, a soft gold alloy (BiOcclus Inlay), a CoCr alloy (Remanium 2000), a resin cement (Variolink II) and a zinc oxide phosphate cement (Harvard) was investigated using the ACTA-machine. Sample chambers of eight sample wheels were prepared with pure materials or combinations of human tooth substance, alloys and cement, simulating an inlay-like situation. After 100,000 and 200,000 cycles in a millet suspension with a spring force of 20 N, the amount of abraded material was profilometrically measured and evaluated by 3D surface data analysis. After 200,000 cycles, the materials demonstrated a mean loss of 0.41 microm for CoCr, 51 microm for gold, 57 microm for enamel, 164 microm for dentin, 79 microm for Variolink and 369 microm for Harvard. Using ANOVA and the Games-Howell-test, resin cement, enamel and gold were a subset not shown to differ, as was zinc phosphate cement and dentin. CoCr demonstrated the least wear and differed significantly from all materials. Enamel wear was significantly reduced in mixed chambers with CoCr, and gold after 200,000 cycles compared to enamel in pure chambers. In summary, a soft gold alloy can be recommended for inlays when considering three-body abrasion since the wear rate of the "soft" gold alloy corresponded to that of human enamel.

Abstract
Tumor necrosis factor alpha (TNFalpha) interferes with insulin signaling in adipose tissue and may promote insulin resistance. Insulin resistance is associated with vascular injury, but little is known about the interaction of TNFalpha and insulin in the vasculature. By activating the Insulin receptor (IR) --> IRS-1 --> phosphatidylinositol-3-kinase (PI3K) --> Akt-pathway, insulin protects vascular smooth muscle cells (VSMC) from undergoing apoptosis. We therefore investigated the effect of TNFalpha on insulin's antiapoptotic signaling in rat aortic VSMC. Insulin induced rapid tyrosine-phosphorylation of the IR and IRS-1 and caused a 2.8-fold increase of IRS-1-bound PI3K. TNFalpha had no effect on insulin-induced tyrosine-phosphorylation of IR or IRS-1, but inhibited insulin-stimulated IRS-1/PI3K-association by 84%. Insulin-induced phosphorylation of Akt downstream of PI3K was inhibited by TNFalpha in a similar pattern. We next examined the effect of TNFalpha on insulin's protective actions on H(2)O(2)-induced apoptosis. Insulin alone prevented 72.8% of H(2)O(2)-induced apoptosis, which was significantly inhibited by TNFalpha. TNFalpha alone did not induce apoptosis. In contrast, TNFalpha had no effect on PDGF-induced antiapoptotic signal transduction via Akt. Thus, TNFalpha selectively interferes with insulin's antiapoptotic signaling in VSMC by inhibiting the association of IRS-1/PI3K and the downstream activation of Akt.

Abstract
Monocyte chemotactic protein 1 (MCP-1)-directed transendothelial migration of monocytes plays a key role in the early development of atherosclerosis. Migration of monocytes requires degradation of extracellular matrices, a process that involves matrix metalloproteinases (MMP) and tissue inhibitors of MMPs (TIMP). Recent studies suggest that the alpha1-adrenergic receptor antagonist doxazosin (Dox) might have antiatherosclerotic effects, although the underlying mechanisms are poorly understood. The purpose of the present study was to determine the effects of Dox on MCP-1-directed monocyte migration, MMP-9 activity, and TIMP-1 expression. MCP-1 (50 ng/ml) stimulated migration of human peripheral blood monocytes (HPBM) 2.7+/-0.42-fold and THP-1 human monocytes 5.9+/-0.83-fold compared with unstimulated control. Dox inhibited MCP-1-induced migration in a dose-dependent manner, with a maximal reduction at 10 microM of 69.5+/-5.9% in HPBM and 72.2+/-3.2% in THP-1 cells. Dox blocked migration even after pretreatment with phenoxybenzamine, an irreversible alpha1-adrenergic receptor antagonist (HPBM: phenoxybenzamine 1 microM + Dox 10 microM, 71.9+/-2.2% inhibition; THP-1 cells: phenoxybenzamine 1 microM + Dox 10 microM: 78+/-7.7% inhibition), suggesting that the antimigratory activity of Dox is mediated through a novel mechanism unrelated to its blocking of the alpha1-adrenergic receptor. Dox (10 microM) inhibited MMP-9 activity by 67.6+/-10.5%, whereas MMP-9 protein levels were not affected. Also, Dox increased PMA-induced-tissue inhibitor of MMPs-1 (TIMP-1) expression by 134.4+/-6.6%. Dox 10 microM. The present study demonstrates a potential novel antiatherosclerotic action of Dox by blocking MCP-1-directed monocyte migration, which might be partly mediated by inhibition of MMP-9 activity.

Abstract
The aim of this study was to investigate whether transformation of quiescent vascular smooth muscle cells (VSMCs) into proliferating secretory cells is accompanied by an expression of processing enzymes that activate de novo-synthesized growth factors. Three enzymes belonging to the family of the kexin/subtilisin-like mammalian proprotein convertases (PCs), furin, PC5, and PC7, were found to be upregulated after balloon denudation in vivo. To determine their importance in these cell processes, we investigated their gene regulation using a short-term organ culture system. After incubation of rat aorta for 4 and 24 hr in serum-free medium, we demonstrated a significant induction of VSMC proliferation. The affected subset of VSMCs, positive for alpha-smooth muscle actin, also expressed proliferating cell nuclear antigen (PCNA). Our results revealed a parallel upregulation of furin, PC5, and PC7 in PCNA-immunolabeled cells. As a substrate model for comparison with PCs we used nerve growth factor (NGF). NGF is known to be activated by PCs. As shown by Northern blotting analysis, NGF mRNA concentration was significantly increased in cultured explants. NGF was released into the culture medium. In conclusion, both PCs and NGF are coordinately modulated on induction of VSMC proliferation.

Abstract
Neointima formation involves tissue expression of matrix proteins and growth factors. The role of alphavbeta3, but not alphavbeta5 integrin in vascular cells has been sufficiently investigated. The aim of the present study was to determine and compare the function of alphavbeta3 and alphavbeta5 integrins in rat aortic (RASMC) and human coronary vascular smooth muscle cells (HCSMC) and to characterize their expression accompanying neointima formation in vivo. RASMC and HCSMC express alphavbeta3 and alphavbeta5 integrin subunits. The alphavbeta5 integrin predominantly mediated adhesion of RASMCs to vitronectin and spreading on vitronectin via RGD-binding sequences. In contrast, the alphavbeta3 integrin did not contribute to the adhesion and spreading on fibronectin, vitronectin, gelatin or collagen I coated layers. PDGF-directed migration through gelatin coated membranes involved both alphavbeta3 and alphavbeta5 integrins. Selective blocking antibodies for alphavbeta3 and alphavbeta5 inhibited migration of RASMC and HCSMC by more than 60 % (p < 0.01). Integrin expression was studied in vivo in thoracic aorta of Sprague Dawley rats before and after balloon injury. In situ hybridization demonstrated low signals for alphav, beta3 and beta5 mRNA in uninjured aorta, which increased significantly at 14 days, localized predominantly in the neointima. Northern analysis of aorta after 14 days of injury also demonstrated an upregulation of alphav, beta3 and beta5 mRNA compared to uninjured aorta. Consistent with the increase in message levels, increased integrin protein expression was seen in the neointima after 7 and 14 days. This study provides evidence that alphavbeta3 and alphavbeta5 are elevated during neointima formation in the rat and indicates a novel role for alphavbeta5 participating in mechanisms regulating smooth muscle cell migration.

Abstract
CD40-CD154-mediated signaling has recently been described as playing a role in cellular functions involved in atherosclerotic processes. CD40 is expressed in macrophages, lymphocytes, endothelial cells, and vascular smooth muscle cells. However, cross-sectional studies investigating the expression of CD40 in atherosclerotic lesions are lacking. In the present study the expression of CD40 was studied in atherosclerotic lesions from 43 patients classified according to the World Health Organization criteria. Serial immunohistologic stainings of human iliac arteries from 43 patients were performed using monoclonal antibodies. Lesions were classified according to World Health Organization criteria, and CD40 expression was analyzed with regard to cell morphology and cellular markers by 2 independent observers. Human atherosclerotic lesions revealed a significant increase in intimal thickness, number of inflammatory infiltrates, and CD40-positive macrophages and vascular smooth muscle cells with progression of the lesions. This increase was most prominent from stage 0 to stage I. A significant correlation between intimal thickness and CD40-positive macrophages (r = 0.75, p <0.0005) and CD40-positive vascular smooth muscle cells (r = 0.81, p <0.0005) was observed. Ligation of the cellular CD40 receptor contributes to inflammatory cellular events in human vascular smooth muscle cells. These data suggest a direct association of CD40 expression in atherosclerotic lesions with early plaque development.

Abstract
Monocyte chemotactic protein-1 (MCP-1)-directed transendothelial migration of monocytes plays a key role in the development of inflammatory diseases. Infiltration of tissues by monocytes requires degradation of extracellular matrices, a process that involves matrix metalloproteinases. We studied the effects of peroxisome proliferator-activated receptor (PPAR) gamma, alpha, and retinoid X receptor alpha (RXRalpha) ligands on MCP-1-directed migration and matrix metalloproteinase expression of a human acute monocytic leukemia cell line (THP-1). PPARgamma ligands attenuated MCP-1-induced migration, with 50% inhibition (IC(50)) at 2.8 microM for troglitazone and 4.8 microM for rosiglitazone. PPARalpha ligands WY-14643 (IC(50): 0.9 microM) and 5,8,11,14-eicosatetranoic acid (IC(50): 9.9 microM), and the potent RXRalpha ligand AGN 4204 (IC(50): 3.6 nM) also blocked monocyte migration. Troglitazone, rosiglitazone, or AGN 4204 inhibited phorbol 12-myristate 13-acetate (PMA)-induced matrix metalloproteinase-9 expression. PPARalpha activators WY-14643 and 5,8,11,14-eicosatetraynoic acid, however, had no inhibitory effect. AGN 4204 increased PMA-induced tissue inhibitor of matrix metalloproteinases-1 (TIMP-1) expression, whereas all PPAR ligands showed no effect. All PPAR and RXRalpha ligands blocked chemotaxis of THP-1 monocytes in the absence of a matrix barrier. This study demonstrates that activated PPARs and RXRalpha, block MCP-1-directed monocyte migration, mediated, at least in part, through their effects on matrix metalloproteinase-9 or TIMP-1 production, or chemotaxis.

Abstract
OBJECTIVES Angiotensin II (Ang II) induces fibroblast proliferation and collagen synthesis in the myocardium, but its precise mechanisms of action in human hearts are still unknown. Therefore, we investigated whether Ang II directly affects the collagen mRNA content in the human myocardium and in isolated human cardiac fibroblasts or whether the growth factors TGFbeta-1 and osteopontin are involved in this process. METHODS AND RESULTS I In a first set of experiments, the direct effect of Ang II on collagen I, TGFbeta-1 and osteopontin mRNA content in fresh samples of human atrial myocardium was determined by the use of a short stimulation period. After 4 h, Ang II-stimulated atrial samples gave a significantly higher expression of both TGFbeta-1 (183+/-21% of control, p<0.05) and osteopontin mRNA (275+/-58%, p<0.02) than the controls. In contrast, the expression of collagen I mRNA was unchanged (95+/-8%). Stimulation with TGFbeta-1 led to an increase in collagen I and III mRNA (127+/-10%, p<0.05; 140+/-15%, p<0.02). METHODS AND RESULTS II In a second protocol, to assess the effects of longer stimulation periods, we determined the effects of Ang II and its potential mediator TGFbeta-1 on collagen I, III and fibronectin mRNA expression and on proliferation of cultured human cardiac fibroblasts. Ang II caused a dose-dependent stimulation of proliferation but did not affect collagen I, II or fibronectin mRNA content after 24 h. In contrast, TGFbeta-1 stimulation significantly increased collagen I and III mRNA expression (124+/-5% and 128+/-5%, p<0.002). CONCLUSIONS In the human heart, Ang II does not directly increase collagen or fibronectin mRNA, but it does increase TGFbeta-1 and osteopontin mRNA expression. Since TGFbeta-1 induces collagen I and III mRNA in atrial samples and in isolated cardiac fibroblasts, it may represent a necessary mediator of the Ang II effects in the human heart.

Abstract
Troglitazone (TRO) is an oral insulin-sensitizer that has direct effects on the vasculature to inhibit cell growth and migration. In vascular smooth muscle cells (VSMCs), insulin transduces a mitogenic signal that is dependent on the ERK1/2 MAP kinases. We examined the effects of TRO on this pathway and found that it inhibits mitogenic signaling. In quiescent VSMCs, insulin (1 microM) induced a 3.2-fold increase in DNA synthesis. TRO (1-20 microM) inhibited insulin-stimulated DNA synthesis by 72.8% at the maximal concentration. TRO at I and 10 microM had no significant effect on insulin-stimulated ERK1/2 activity. At 20 microM, however, TRO modestly enhanced insulin-stimulated ERK1/2 activity by 1.5-fold. ERKs transduce a mitogenic signal by phosphorylating transcription factors such as Elk-1. which regulate critical growth-response genes. We used GAL-Elk-1 expression plasmids to detect ERK-dependent activation of Elk-1. TRO at 1-20 microM potently inhibited insulin-stimulated, ERK1/2-dependent Elk-1 transcription factor activity. Neither early steps in insulin signaling nor the phosphatidylinositol 3-kinase (PI3K) branch of this pathway were affected by TRO, because it had no effect on IRS-1 phosphorylation, PI3K/IRS-1 association, or Akt phosphorylation. Because TRO is a known ligand for the nuclear transcription factor peroxisome proliferator-activated receptor gamma (PPARgamma), we tested two other ligands for this receptor, rosiglitazone (RSG) and 15-deoxy-delta12,14 prostaglandin J2 (15d-PGJ2). Both also inhibited insulin-induced DNA synthesis. In summary, these data show that TRO inhibits mitogenic signaling by insulin at a point distal of ERK1/2 activation, potentially by a PPARgamma-mediated inhibition of ERK-dependent phosphorylation and activation of nuclear transcription factors that regulate cell growth.

Abstract
We recently demonstrated that alpha(v)beta(3) integrins are involved in the mechanisms of angiotensin II (Ang II)-induced DNA synthesis and collagen gel contractions in rat cardiac fibroblasts (CFBs), cellular mechanisms that are relevant for cardiac remodeling. The aim of the present study was to elucidate the effect of Ang II and other growth factors on the regulation of the alpha(v)beta(3) integrins in fibroblasts from neonatal rat hearts. The alpha(v)beta(3) integrin receptor expression was significantly increased (P<0.05) at the mRNA level after treatment with Ang II, transforming growth factor-beta(1) (TGF-beta(1)), and platelet-derived growth factor (PDGF) for 8 and 16 hours. The surface expression of the alpha(v) and beta(3) integrin subunits was elevated after 32 and 48 hours (P<0.05) as determined with flow cytometry. To investigate fibroblast motility, we performed chemotaxis experiments with transwell chambers. Ang II was chemotactic for CFBs, as tested with checkerboard experiments. The chemotactic effect was concentration dependent and was completely blocked by Ang II type 1 receptor blockers but not by Ang II type 2 receptor blocker PD 123319. Ang II- and PDGF-BB-mediated chemotaxis could be significantly inhibited by RGD peptides and the blocking antibodies against alpha(v)beta(3) integrin (both P<0.01). Adhesion of CFBs to vitronectin was partially inhibited by an antibody to alpha(v)beta(3) integrin but was mainly mediated by an alpha(v)beta(5) integrin. Relevant in vivo expression of alpha(v)beta(3) integrin by CFBs was confirmed with in situ hybridization with probes for alpha(v) and beta(3) mRNA in rat hearts. The present study demonstrates that the expression of alpha(v)beta(3) integrin is augmented by Ang II, PDGF, and TGF-beta(1) in neonatal CFBs. Furthermore, this integrin is involved in the chemotaxis, motility, and adhesion of CFBs. The present findings support the current concept that integrins participate in the control of fibroblast behavior during cardiac remodeling mechanisms.

Abstract
human umbilical venous endothelial cells. 7E3 binding correlated with alphavbeta3-expression in all cell types. Integrin-mediated cell functions were analysed with adhesion and spreading assays on vitronectin. In human umbilical venous endothelial cells, these functions were mediated by alphavbeta3 and in human iliac arterial smooth muscle cells by alphavbeta5. In human umbilical venous smooth muscle cells, both vitronectin receptors were involved. Abciximab potently inhibited alphavbeta3-mediated cell adhesion and spreading. With tirofiban, no significant inhibition of vascular cell functions was observed. The present data demonstrate that vitronectin-cell interactions in vascular cells are mediated via two distinct integrin-receptors, alphavbeta3 and alphavbeta5. Abciximab, which solely inhibits alphavbeta3-mediated cell functions, may be particularly effective in human endothelium and in beta3-integrin expressing vascular smooth muscle cells.

Abstract
beta(1)-Integrins play an important role for adhesion and spreading of human smooth muscle cells. In the present study we examined the influence of angiotensin II and platelet-derived growth factor (PDGF)-BB on beta(1)-integrin-dependent functions of human smooth muscle cells obtained from iliac arteries. Treatment of these cells with PDGF-BB (20 ng/mL) and Angiotensin II (1 micromol/L) did not change beta(1)-integrin expression up to 48 hours as analyzed by flow cytometry and reverse transcription polymerase chain reaction. beta(1)-integrins predominantly mediated adhesion of human smooth muscle cells to collagen I (79.7+/-4.4%, P<0.01) and fibronectin (66. 6+/-2.4%, P<0.01). Treatment of smooth muscle cells with Angiotensin II (1 micromol/L) and PDGF-BB (20 ng/mL) significantly increased the adhesion to collagen I by 56.5% and 44.3%, respectively, and to fibronectin by 49.6% and 36.4%, respectively (all P<0.05). Angiotensin II-induced effects were mediated by the AT(1) receptor. The PDGF-BB mediated increase of adhesion was inhibited in the presence of genestein, a tyrosine-kinase inhibitor and by protein kinase C downregulation with phorbol 12-myristate 13-acetate. Spreading of smooth muscle cells also was beta(1)-integrin dependent on collagen I and alpha(5)beta(1)-integrin dependent on fibronectin. Angiotensin II and PDGF-BB increased cell spreading on fibronectin up to 276% and 318%, respectively, and on collagen I up to 133% and 138% (all P<0.05). These increases were significantly inhibited by blocking antibodies against beta(1)-integrin, alpha(5)-integrin on fibronectin, the AT(1) receptor blocker irbesartan, and genestein. The present data demonstrate that angiotensin II and as well PDGF-BB enhance beta(1)-integrin-dependent adhesion and spreading of human vascular smooth muscle cells. Furthermore, the experiments with PDGF suggest an involvement of protein kinase C activation leading to these enhanced effects.

Abstract
Angiotensin II (Ang II) plays an important role in cardiac remodeling through stimulation of proliferation and extracellular matrix (ECM) production in cardiac fibroblasts. Integrins are a family of transmembrane receptors that mediate the attachment of cells to ECM. We hypothesized that Ang II regulation of integrins further contributes to its role in cardiac remodeling. We cultured adult rat cardiac fibroblasts with and without Ang II (100 nmol/L) to determine the effects on mRNA and protein levels of integrins, as well as alpha-actinin and other cytoskeletal proteins that link to integrins at the site of focal adhesions. Ang II was also added in the presence of irbesartan (10 micromol/L), a specific Ang II type 1 (AT(1)) receptor antagonist, or PD 123319 (10 micromol/L), a specific Ang II type 2 receptor antagonist. To investigate the function of these integrins, we determined the effects of blocking antibodies on Ang II-induced adhesion to ECM. We also treated spontaneously hypertensive rats (SHR) with an AT(1) receptor blocker, losartan, or with hydralazine to investigate integrin and alpha-actinin expression in treated and untreated SHR. Ang II enhanced alpha(v), beta(1), beta(3), and beta(5) integrins; osteopontin; and alpha-actinin mRNA and protein levels in cardiac fibroblasts. All of these effects were inhibited by irbesartan but not by PD 123319. Pretreatment of cardiac fibroblasts with Ang II enhanced cell attachment to ECM proteins and induced focal adhesion kinase phosphorylation. Blocking antibodies to beta(3) and alpha(v)beta(5) attenuated Ang II-induced adhesion. In SHR, ventricular alpha(v) and beta(5) integrin expression and alpha-actinin were increased compared with those in Wistar-Kyoto rats. Although both losartan and hydralazine lowered mean arterial pressure and decreased peripheral vascular resistance, only losartan attenuated the increased integrin, alpha-actinin, fibronectin laminin, and osteopontin expression and the increased left ventricular mass (as determined with echocardiography). Hydralzine had none of these effects. Although both agents attenuated beta-myosin heavy chain expression, a marker of hypertrophy, losartan had a greater effect. These results suggest that integrins and alpha-actinin are upregulated by Ang II and in left ventricular hypertrophy and that the block of expression of these proteins through inhibition of the AT(1) receptor is associated with attenuation of the hypertrophic response. Ang II induces integrin and alpha-actinin expression in cardiac fibroblasts that is associated with adhesion and left ventricular hypertrophy and blocked through inhibition of the AT(1) receptor.

Abstract
A reduction of renal kallikrein has been found in non-insulin-treated diabetic individuals, suggesting that an impaired renal kallikrein-kinin system (KKS) contributes to the development of diabetic nephropathy. We analyzed relevant components of the renal KKS in non-insulin-treated streptozotocin (STZ)-induced diabetic rats. Twelve weeks after a single injection of STZ, rats were normotensive and displayed hyperglycemia, polyuria, proteinuria, and reduced glomerular filtration rate. Blood bradykinin (BK) levels and prekallikrein activity were significantly increased compared with controls. Renal kallikrein activity was reduced by 70%, whereas urinary BK levels were increased up to threefold. Renal kininases were decreased as indicated by a 3-fold reduction in renal angiotensin-converting enzyme activity and a 1.8-fold reduction in renal expression of neutral endopeptidase 24.11. Renal cortical expression of kininogen and B2 receptors was enhanced to 1.4 and 1. 8-fold, respectively. Our data suggest that increased urinary BK levels found in severely hyperglycemic STZ-diabetic rats are related to increased filtration of components of the plasma KKS and/or renal kininogen synthesis in combination with decreased renal kinin-degrading activity. Thus, despite reduced renal kallikrein synthesis, renal KKS is activated in the advanced stage of diabetic nephropathy.

Abstract
While the cellular mechanisms of atherosclerosis have been intensively studied, the mechanisms leading to preferential localization of atherosclerotic lesions are less well understood. To further define these mechanisms, endothelial cells from coronary arteries, i.e., vessels with frequent atherosclerotic lesions, were isolated and grown in vitro. In order to compare the reactions of both cell types, endothelial cells derived from microvessels of human hearts were isolated and cultured under identical conditions. Incubation of endothelial cells with oxidized LDL (75 microg/ml protein) induced a significant increase in PAI-1 activity (182%, p < 0.05) in coronary macrovascular endothelial cells. This stimulatory effect of ox-LDL was less significant in microvascular endothelial cells (144%, p < 0.05). n-LDL did not influence secreted PAI-1 activity. Stimulation with angiotensin II induced expression of E-selectin more effectively in coronary macrovascular than in microvascular endothelial cells. In addition, angiotensin II-induced E-selectin expression led to increased E-selectin-dependent adhesion of HL60 cells to coronary macrovascular endothelial cells under flow conditions, while only little effect was observed with cardiac microvascular endothelial cells. In contrast, L-selectin-dependent adhesion, which has been shown to play an important role in inflammatory reactions, was preferentially observed in cardiac microvascular endothelial cells and could only be stimulated with TNFalpha, not by angiotensin II. Therefore, these cellular differences may in part explain specific properties of cardiac endothelial cells: Such that atherosclerotic lesions are localized in macrovascular vessel segments, whereas inflammatory responses are predominantly found in the microvasculature.
