Abstract
The present study reports for the first time the presence of giant crystals in mitochondria of equine chondrocytes. These structures show dark contrast in TEM images as well as a granular substructure of regularly aligned 1-2 nm small units. Different zone axes of the crystalline structure were analysed by means of Fourier transformation of lattice-resolution TEM images proving the crystalline nature of the structure. Elemental analysis reveals a high content of nitrogen referring to protein. The outer shape of the crystals is geometrical with an up to hexagonal profile in cross sections. It is elongated, spanning a length of several micrometres through the whole cell. In some chondrocytes, several crystals were found, sometimes combined in a single mitochondrion. Crystals were preferentially aligned along the long axis of the cells, thus appearing in the same orientation as the chondrocytes in the tissue. Although no similar structures have been found in the cartilage of any other species investigated, they have been found in cartilage repair tissue formed within a mechanically stimulated equine chondrocyte construct. Crystals were mainly located in superficial regions of cartilage, especially in joint regions of well-developed superficial layers, more often in yearlings than in adult horses. These results indicate that intramitochondrial crystals are related to the high mechanical stress in the horse joint and potentially also to the increased metabolic activity of immature individuals.

Abstract
BACKGROUND Oxidative stress (OS) represents an important pathogenetic factor of acute liver failure and chronic liver diseases. To elucidate whether the liver itself is a major source of OS, the present study was performed to assess OS and antioxidant status in an anhepatic porcine model. METHODS Six pigs underwent a total hepatectomy, five pigs were sham operated. OS and antioxidant status were evaluated by measuring plasma concentrations of malondialdehyde (MDA), xanthine oxidase (XO), superoxide dismutase (SOD) and the ferric reducing ability of plasma (FRAP). They were sampled at the start of the experiment, immediately after surgery, and then at 8 and 16 hours post hepatectomy. RESULTS Increased concentrations of MDA were observed in anhepatic pigs postoperatively (p < 0.02) and 8 hours after hepatectomy (p < 0.003) compared to controls. XO activity increased soon after hepatectomy (22.6 ± 5.4 mU/L versus 3.3 ± 2.1 mU/L in sham animals, p < 0.03) but returned to normal values in the further course. SOD levels did not change during the observational period in both groups. FRAP values rose significantly in the anhepatic animals compared to control (p < 0.015). A significant positive correlation was observed between MDA levels and FRAP levels (Spearman's ρ = 0.62; p < 0.0001). CONCLUSIONS These findings show that hepatectomy does not completely prevent the occurrence of OS because the production and regulation of OS are also located outside the liver.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is more prevalent in women. Our goal is to determine the effects of 17β-estradiol (E2) on the development of fibrosis and to compare circulating levels of estrogens in SSc patients and healthy controls. METHODS Using primary human dermal fibroblasts, we evaluated the effect of E2 on fibronectin (FN) expression with and without the estrogen receptor (ER) antagonist ICI 182,780, inhibitors of signaling, propyl-pyrazole-triol, an ERα specific ligand, and genistein, an ERβ selective ligand, to identify the signaling pathways mediating E2's effect. We confirmed the fibrotic effect of E2 in human skin using an ex vivo organ culture model. Lastly, we measured levels of E2 and estrone in serum samples from SSc patients with diffuse cutaneous involvement and healthy controls using mass spectrometry. RESULTS E2 increased expression of FN in dermal fibroblasts. ICI 182,780, inositol-1,4,5-triphosphate inhibitor, and p38 mitogen-activated protein kinase inhibitor blocked the effects of E2 on FN. Propyl-pyrazole-triol, but not genistein, significantly increased FN expression. Ex vivo, E2 induced fibrosis of human skin. The effects of E2 were abrogated by ICI 182,780. Circulating levels of E2 and estrone were significantly increased in sera of patients with diffuse cutaneous SSc. CONCLUSION Our findings implicate estrogens in the fibrotic process and may explain the preponderance of SSc in women. ICI 182,780 or other ER signaling antagonists may be effective agents for the treatment of fibrosis.

Abstract
We present a facile method for the preparation of bimetallic AuAg nanoparticles (NPs) with controlled size and composition rendering them ideally suitable for optical and catalytic applications. In analogy to methods for the generation of monometallic Au and Ag NPs, AuAg NPs were prepared inside polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) block-copolymer micelles formed in toluene, by loading the P4VP cores of the micelles first with AgNO(3) and then with HAuCl(4). In contrast to the reverse sequence of loading, homogenously bimetallic AuAg particle arrays were achieved after reduction carried out in solution with hydrazine monohydrate as the reducing agent. TEM reveals that stable and spherical NPs can be prepared well separated from one another and with a narrow size distribution with diameters of ∼3 nm. The bimetallic NP composition was confirmed by energy-dispersive X-ray spectroscopy (EDX) of single NPs. The atomic ratio of Ag and Au contained in single particles is in good agreement with the relative concentrations of both metals used in the synthesis which was confirmed by atomic absorption spectroscopy. The atomic ratio Au : Ag was systematically varied between 3 : 1 and 1 : 3. For all ratios UV-vis spectra showed a single plasmon band. Its wavelength varied from 430 for Au : Ag = 1 : 3 to 515 nm for Au : Ag = 3 : 1, showing a linear dependence on the relative amount of gold within the range of plasmon wavelengths from monometallic gold (538 nm) to silver (415 nm).

Abstract
BACKGROUND AND AIMS Severe intoxication following acetaminophen overdose is the most common cause of acute liver failure (ALF) in many Western European and North American countries. A reproducible large animal model of acetaminophen intoxication has not been successfully evaluated previously. METHODS Eight male pigs underwent acetaminophen intoxication receiving an initial enteric bolus of 250 mg/kg body weight acetaminophen followed by an acetaminophen plasma level (300-450 mg/l) adapted enteric maintenance dose of 1,000-3,000 mg/h to the onset of ALF (prothrombin time value <30%). Vital and ventilation parameters were continuously recorded until death. Saline, hydroxyethyl starch, fresh frozen plasma and erythrocyte units were used for volume substitution, and norepinephrine to prevent severe hypotension. RESULTS All animals developed ALF after 25 ± 3 h, which was confirmed by laboratory values, the clinical course and histological examinations. All animals died due to ALF after a further 21 ± 5 h, precipitated by cerebral edema. CONCLUSIONS Using an initial enteric acetaminophen bolus, followed by body weight-adapted acetaminophen plasma level intoxication, it was possible to establish a reproducible, clinically relevant porcine model which may be used for the investigation of novel therapeutic approaches in this life-threatening condition.

Abstract
Measuring antibodies to Bordetella pertussis antigens is mostly done by enzyme-linked immunosorbent assays (ELISAs). We compared the performance of ELISA kits that were commercially available in Germany. Eleven measured IgG antibodies, and nine measured IgA antibodies. An in-house ELISA with purified antigens served as a reference method. Samples included two WHO reference preparations, the former Food and Drug Administration (FDA)/Center for Biologics Evaluation and Research (CBER) reference preparations, serum samples from patients with clinically suspected pertussis, and serum samples from patients having received a combined tetanus, diphtheria, and pertussis (Tdap) vaccination. Kits using pertussis toxin (PT) as an antigen showed linearity compared to the WHO Reference preparation (r2 between 0.82 and 0.99), and these kits could quantify antibodies according to the reference preparation. ELISA kits using mixed antigens showed no linear correlation to the reference preparations. Patient results were compared to results of in-house ELISAs using a dual cutoff of either ≥100 IU/ml anti-PT IgG or ≥40 IU/ml anti-PT IgG together with ≥12 IU/ml anti-PT IgA. The sensitivities of kits measuring IgG antibodies ranged between 0.84 and 1.00. The specificities of kits using PT as an antigen were between 0.81 and 0.93. The specificities of kits using mixed antigens were between 0.51 and 0.59 and were thus not acceptable. The sensitivities of kits measuring IgA antibodies ranged between 0.53 and 0.73, and the specificities were between 0.67 and 0.94, indicating that IgA antibodies may be of limited diagnostic value. Our data suggest that ELISAs should use purified PT as an antigen and be standardized to the 1st International Reference preparation.

Abstract
Infection by an attenuated replication-competent murine retrovirus (Friend leukemia virus-FLV4), but not other non-transforming retroviruses, stimulated rejection of transplantable thymomas (RL-cell line) and subsequent tumor immunity in syngeneic mouse recipients. FLV-infected RL-cells (RL-FLV) were unaltered in their in vitro growth, and grew progressively to kill sublethally irradiated animals and nude mice. Primary RL-FLV rejection was due to induction of increased natural killer (NK)-cell activity limited to peritoneal sites of tumor inoculation with a minor cytolytic macrophage population. Syngeneic mutant beige (NK-deficient) mice similarly rejected RL-FLV cells with increased peritoneal NK-cell activity and acquired immunity to the parental RL-tumor. While RL-FLV stimulated far greater peritoneal NK activity than did other tested retrovirus-infected RL-cells, the inherent susceptibility of these cells to lysis by normal NK cells was not altered by virus. RL-FLV induced NK effectors showed an indiscriminate lysis pattern that was independent of target cell type and retrovirus expression.

Abstract
Murine oncovirus antigens represent excellent targets for immune recognition, and virus-associated tumors are generally susceptible to various immunotherapy protocols. Virus-negative tumors, however, are nonimmunogenic and refractory to immunologic control. Therefore, the feasibility of the introduction of antigens onto non-virus-expressing tumors in situ in inbred C57BL/6J mice by systemic administration of nononcogenic murine retroviruses was investigated. Two classes of murine fibrosarcomas were studied: a 3-methylcholanthrene-induced fibrosarcoma syngeneic to C57BL/6 mice (MCA-FS) and a Harvey murine sarcoma virus-transformed, nonproducer fibrosarcoma syngeneic to C57BL/6 mice (H-NP). Both were found to be devoid of infectious ecotropic murine leukemia virus (MuLV) or MuLV antigens. A single dose of Friend murine leukemia virus (F-MuLV) was used to superinfect MCA-FS- and H-NP-induced tumors in vivo and converted these tumors to a highly productive, virus-positive state. In vivo superinfected tumors were indistinguishable from their preinfected counterparts by competition radioimmunoassays for the virion's major envelope glycoprotein, gp71, and its group-specific antigen, p30, and by assays for infectious virus. Analysis of virus from tumor extracts proved that the antigenic specificity of the superinfected tumor was provided by F-MuLV administered systemically to the animals. Finally, an immunoperoxidase technique, applied to tumor cross sections, demonstrated the uniform appearance of viral antigens in the superinfected tumors.

Abstract
Tissue distribution of radiation leukemia virus (RadLV) was examined after its inoculation into normal C57BL/6J (B6) mice, B6 mice bearing a transplantable, non-virus-producing thymic lymphoma (RL12-NP), and B6 mice bearing a transplanted non-virus producing, Harvey murine sarcoma virus-transformed fibrosarcoma. Virus expression was determined by competition radioimmunoassay for murine leukemia virus (MuLV) p30 (predominant group-reactive antigen of MuLV) and for RadLV p12 (a highly type-specific MuLV polypeptide) and by membrane immunofluorescence for cell surface gp71 (predominant envelope glycoprotein of MuLV). Normal adult B6 mice were given three sequential iv injections of RadLV and were examined several times up to 200 days later for the appearance of neoplastic disease or expression of virion antigens. No clinical abnormalities were noted, and animals remained healthy for greater than 200 days. Significant levels of MuLV p30 and RadLV p12 were detected only in the thymuses. Organs and tumors from RL12-NP-inoculated animals contained low or nondetectable levels of virion antigens. Inoculation of mice with RL12-Rad, a cell line derived by in vitro infection of RL12-NP cells with RadLV, produced widespread, discrete metastatic tumors and infiltrated the lymphoid organs of B6 mice in a pattern identical to that observed after administration of RL12-NP cells. Lymphoid organs of RL12-Rad-inoculated animals expressed variable levels of virion antigens reflecting differences in the extent of tumor cell infiltration as opposed to virus spread from tumor to host cells. Administration of infectious RadLV systemically into RL12-NP tumor-bearing animals converted these tumors to viron antigen expressors with levels in superinfected tumors equivalent to those found in RL12-Rad-induced tumors. Infection was highly selective, and host tissues were minimally contaminated by the inoculated virus. Part of this selectivity was explained by the thymotropic property of RadLV. A rapidly dividing murine fibrosarcoma was not infected by RadLV, but this same non-virus-expressing tumor could be infected by common fibrotropic MuLV isolates.

Abstract
Murine leukemia viruses were previously demonstrated to be able to infect efficiently non-virus-expressing tumors in vivo. In the present study the infectivity and tissue distribution of Friend murine leukemia virus (F-MuLV) in normal and tumor-bearing C57BL/6J (B6) mice were examined. Two syngeneic fibrosarcoma-inducing cell lines were used: Cells from a 3-methylcholanthrene-induced fibrosarcoma syngeneic to B6 mice (MCA-FS) and cells from a Harvey murine sarcoma virus-transformed, nonproducer sarcoma syngeneic to B6 mice (H-NP) were described in the preceding study. Both cell lines lacked ecotropic viral expression. F-MuLV produced in vitro was rarely able to infect normal adult B6 tissue in vivo and lacked pathogenic potential. Adult animals receiving F-MuLV remained clinically normal during 20 months of follow-up and had no detectable viremia, although some had persistently infected thymuses and long bones. In animals receiving a single dose of F-MuLV given to superinfect either the MCA-FS or the H-NP induced tumors, virion antigens were found only in tumor tissue and not in the normal host organs studied. Infectious virus was abundant in tumors; occasionally, it was found in thymuses and long bones of animals bearing superinfected H-NP tumors but rarely in other organs. Localization of F-MuLV in MCA-FS tumors appeared to be more selective with rare contamination of host organs. The presence of a rescuable sarcoma genome in H-NP may explain the discrepancy between MCA-FS and H-NP tumors. The possibility of increasing the efficiency and selectivity of infection as well as the therapeutic application of this technique are discussed.

Abstract
The rehabilitation of patients who underwent an intervertebral disc operation is, inter alia, decisively determined by after-care. In this context, attention must be drawn to the post-surgical goal-oriented physical therapy which is important for the healing process, re-adaptation and duration of treatment. The Brunkow special isometric exercises bring about a quick and permanent re-adaptation and provide a good basis for the patient's exercise at home.
