Abstract
The objective of this study was to evaluate the impact of coccidiosis on bone quality and antioxidant status in the liver and bone marrow of broiler chickens. A total of 360 13-day old male broilers (Cobb 500) were randomly assigned to different groups (negative control, low, medium-low, medium-high, and highest dose groups) and orally gavaged with different concentrations of Eimeria oocysts solution. Broiler tibia and tibia bone marrow were collected at 6 days post-infection (6 dpi) for bone 3-D structural analyses and the gene expression related to osteogenesis, oxidative stress, and adipogenesis using micro-computed tomography (micro-CT) and real-time qPCR analysis, respectively. Metaphyseal bone mineral density and content were reduced in response to the increase of Eimeria challenge dose, and poor trabecular bone traits were observed in the high inoculation group. However, there were no significant structural changes in metaphyseal cortical bone. Medium-high Eimeria challenge dose significantly increased level of peroxisome proliferator-activated receptor gamma (PPARG, p < 0.05) and decreased levels of bone gamma-carboxyglutamate protein coding gene (BGLAP, p < 0.05) and fatty acid synthase coding gene (FASN, p < 0.05) in bone marrow. An increased mRNA level of superoxide dismutase type 1 (SOD1, p < 0.05) and heme oxygenase 1 (HMOX1, p < 0.05), and increased enzyme activity of superoxide dismutase (SOD, p < 0.05) were found in bone marrow of Eimeria challenged groups compared with that of non-infected control. Similarly, enzyme activity of SOD and the mRNA level of SOD1, HMOX1 and aflatoxin aldehyde reductase (AKE7A2) were increased in the liver of infected broilers (p < 0.05), whereas glutathione (GSH) content was lower in the medium-high challenge group (p < 0.05) compared with non-challenged control. Moreover, the mRNA expression of catalase (CAT) and nuclear factor kappa B1 (NFKB1) showed dose-depend response in the liver, where expression of CAT and NFKB1 was upregulated in the low challenge group but decreased with the higher Eimeria challenge dosage (p < 0.05). In conclusion, high challenge dose of Eimeria infection negatively affected the long bone development. The structural changes of tibia and decreased mineral content were mainly located at the trabecular bone of metaphyseal area. The change of redox and impaired antioxidant status following the Eimeria infection were observed in the liver and bone marrow of broilers.

Abstract
Maduramicin, an extensively used anticoccidial drug, has been introduced into environment due to poorly absorbed in the intestine of broiler chicken. To understand the potential ecological toxicity of maduramicin on aquatic organisms, acute and subacute toxicity, hemolymph biochemistry, histopathology and the expressions of drug metabolism and stress response genes of crayfish (Procambius clarkii) were investigated in this study. For the first time, the 96 h median lethal concentration (LC50) of maduramicin on crayfish was 67.03 mgL-1 with a 95% confidence interval (54.06-81.32 mgL-1). Then, the crayfish were exposed to 0.7 mgL-1 (1/100 LC50), 3.5 mgL-1 (1/20 LC50) and 7.0 mgL-1 (1/10 LC50) maduramicin for 28 days. Maduramicin significantly altered biochemical parameters including AST, ALT, CK, LDH and ALP of hemolymph in crayfish at several time points. The activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) of crayfish gills, hepatopancreas and abdominal muscle were significantly decreased or elevated by different concentrations of maduramicin treatment at varying time points. Furthermore, histopathological damage of crayfish gills, hepatopancreas and abdominal muscle were observed in a concentration-dependent manner. The expressions of metabolic and stress response genes (CYP450, GST, COX1, COX2, HSP70 and MT) in hepatopancreas of crayfish were significantly up-regulated by maduramicin (7.0 mgL-1) treatment for 8 h to 7 d, and returned to normal levels after the removal of maduramicin for 3-7 days. In conclusion, our findings demonstrated that environmental exposure of maduramicin threaten to the health of crayfish living in the areas nearby livestock farms or pharmaceutical factory. Crayfish exhibited resistance to the stress of maduramicin via activating drug metabolite and detoxification pathways.

Abstract
Maduramicin (MAD) is widely introduced into aquatic environments and results in the contamination of fish products. Worryingly, the consumption of MAD-contaminated crayfish (Procambarus clarkii) may induce symptoms of Haff disease. In this study, to monitor this potential contamination and to understand the residue and elimination characteristics of MAD in edible tissues of crayfish, a sensitive and efficient ultra-performance liquid chromatography-tandem mass spectrometry method was developed, validated, and applied. After extraction with acetonitrile and purification by solid-phase extraction column, multiple-reaction monitoring mass spectrometry with positive ionization mode was used to determine MAD's residues. The limits of detection and of quantification were 6 μg·kg-1 and 20 μg·kg-1, respectively. The fortified recoveries ranged from 74.2% to 110.4%, with relative standard deviation of 1.2% to 10.1%. Furthermore, MAD was completely eliminated after 3 and 5 days from abdominal muscle and hepatopancreas tissues of crayfish, respectively. The maximum residue limits (MRLs) of MAD respectively was 200 μg·kg-1 in muscle and 600 μg·kg-1 in the hepatopancreas, and its withdrawal time in both edible tissues was 25.8 °C·d. Collectively, the results of this study indicate the proposed method is an efficient tool to evaluate the public health risk associated with crayfish consumption.

Abstract
Maduramicin is one of the most extensively used anticoccidial drugs for the treatment of Eimeria spp. infections. However, overdosage, misuse and drug interactions have resulted in the development of ionophore toxic syndrome. Heart and skeletal muscles have been identified as the main target organs of toxicity. In the present study, primary chicken myocardial cells were isolated to investigate the toxicity and underlying mechanisms of maduramicin. Our results showed that maduramicin causes morphological changes and a decrease in the viability of chicken myocardial cells. Annexin V-FITC/PI and 4',6-diamidino-2-phenylindole (DAPI) staining showed a significant increase in the number of apoptotic cells. Furthermore, caspases-3/8/9 were activated at the gene and protein levels and this was accompanied by the upregulation of apoptosis-related genes, including bcl-2, bax, and cytochrome C. Treatment with the pan-caspase inhibitor N-benzyloxycarbonyl-Val-Ala-Asp (O-Me) fluoromethyl ketone (z-VAD-fmk) ameliorated the apoptosis and cytotoxicity. Furthermore, intracellular Ca2+ and reactive oxygen species (ROS) were elevated, whereas mitochondrial membrane potential (MMP) and intracellular glutathione (GSH) decreased with exposure to maduramicin. The antioxidant N-acetyl-cysteine (NAC) had no significant effect on maduramicin-induced cytotoxicity and apoptosis. Taken together, our findings demonstrate that maduramicin is cytotoxic to primary chicken myocardial cells via caspase dependent and independent apoptotic pathways.

Abstract
OBJECTIVE We investigated the clinicopathological characteristics and immunophenotype of female genital system diffuse large B-cell lymphoma (DLBCL) in order to improve diagnosis and therapy efficacy. PATIENTS AND METHODS The clinicopathologic features of 13 cases with primary DLBCL of the female genital system were studied retrospectively. According to the immunophenotypes, 10 cases were classified as germinal center B-cell-like DLBCL and the other 3 as non-center B-cell-like DLBCL. RESULTS The immunohistochemistry data showed that CD20, PAX-5, and CD79a tested positive, while CD3, CD43 and CD45RO tested negative in all 13 cases. In 7 cases EMA was positive, in 9 cases CD10 was positive, in 11 cases bcl-6 was positive, and in 9 cases MUM-1 was tested positive. In one case, the Ki-67 index was less than 59%, in 3 cases Ki-67 index was between 60% to 89% and it was more than 90% in the remaining 9 cases (the median was 90%). All 13 patients underwent hysterectomy, while in 10 of them hysterectomy was followed by chemotherapy. The survival time was 3 to 20 months. CONCLUSIONS Primary diffuse large B-cell lymphoma of the primary female genital system is a rare and highly invasive condition that can be easily misdiagnosed. A complete diagnosis is very important because the treatment and prognosis vary in different histological types. Moreover, the immunohistochemistry is an useful diagnostic method for this type of cancer.

Abstract
Hemostatic factors are involved in the pathogenesis of native coronary artery disease. However, their role in transplant coronary artery disease is less established. To assess the role of hemostatic factors in transplant coronary artery disease we studied 52 consecutive cardiac transplant patients. The presence of transplant coronary artery disease was determined by angiography. Plasma levels of tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), von Willebrand Factor (vWF), and fibrin D-dimer were determined by enzyme-linked immunosorbent assays. Serum lipids were measured by enzymatic methods. Patients with transplant coronary artery disease had higher circulating t-PA (8.6 +/- 0.8 vs. 5.4 +/- 0.6 ng/ml, p = 0.021) and PAI-1 antigen concentrations (38.0 +/- 3.4 vs 25.8 +/- 2.2 ng/ml, p = 0.037). t-PA and PAI-1 antigen concentrations correlated with the severity of angiographic disease (R = 0.34; p = 0.014 for t-PA, and R = 0.45; p = 0.001 for PAI-1). Serum cholesterol levels were higher in patients with transplant coronary artery disease (221 +/- 7.6 vs 191 +/- 9.2 mg/dl, p = 0.039). Serum triglycerides were also higher in patients with transplant coronary artery disease by angiography (246 +/- 38.3 vs 139 +/- 20.8 mg/dl, p = 0.050). Multivariate analysis identified t-PA antigen (p = 0.003) and triglyceride levels (p = 0.038) as independent predictors for the presence of transplant coronary artery disease. We conclude that cardiac transplant patients with evidence of transplant coronary artery disease on coronary angiography have altered hemostatic function which is reflected by elevated levels of circulating t-PA and PAI-1 antigens. The interaction of the hemostatic system and serum lipids in the development of transplant coronary artery disease warrants further study.

Abstract
High-speed flash photographs of laser-induced fragmentation of biliary and renal calculi under water were obtained using one-microsecond-long dye-laser pulses for both illumination and ablation. The photographs show the presence of a bubble with irregularities on the surface that suggest the early presence of debris or microbubbles. Fragmentation occurs before the bubble collapses, suggesting that fragmentation is due to laser-induced acoustic transients rather than to collapse of a laser-induced cavitation bubble.

Abstract
This paper is a report on the first (serological) phase of a study organized by WHO in collaboration with the WHO International Reference Centre for Respiratory Virus Diseases other than Influenza in Bethesda, Md., USA, to define the viral etiology of severe respiratory infections in children, particularly in tropical areas. Paired sera from 528 children up to 5 years old admitted to hospital with severe respiratory illness of probable viral etiology were collected in 10 countries and sent frozen to the International Reference Centre, where standard complement-fixation tests were made for the following agents: parainfluenza virus types 1, 2 and 3, influenza virus types A and B, adenoviruses, respiratory syncytial virus, Mycoplasma pneumoniae, Coxiella burneti and psittacosis-ornithosis.Some 41% of paired sera showed rising antibody titres for one or more of these agents, multiple infections being observed in 8%. In most of the countries the pattern of infection was similar. RS virus was the most important respiratory tract pathogen of early life, particularly in the first year of life and in cases of bronchiolitis and pneumonia; the parainfluenza viruses were next in importance, particularly in cases of croup, but, in contra-distinction to RS virus infections, they were commoner in older children. Influenza, adenoviruses, and M. pneumoniae were of moderate importance, and C. burneti and the psittacosis-ornithosis agents were relatively rare. This pattern is similar to that which has been observed in temperate climates.
