The primary aim of the present study was to investigate the potential effect of high‑pressure carbon dioxide (CO2) pneumoperitoneum on kidneys with severe hydronephrosis and to investigate the possible underlying mechanism. A total of 18 rabbits underwent a surgical procedure inducing severe hydronephrosis. Rabbits were then divided at random into three groups (n=6 each) and subjected to intraabdominal pressure of 0, 8 or 18 mmHg, respectively. CO2 inflation lasted for 90 min in the pneumoperitoneum groups...

Herpesvirus Macaca arctoides (HVMA) has the propensity to transform macaque lymphocytes to lymphoblastoid cells (MAL-1). Inoculation of rabbits with cell-free virus-containing supernatant resulted in the development of malignant lymphomas and allowed isolation of immortalised HVMA-transformed rabbit lymphocytes (HTRL). In this study, the HVMA genome sequence (approx. 167 kbp), its organisation, and novel aspects of virus latency are presented. Ninety-one open reading frames were identified, of which 86 were non-repetitive...

BACKGROUND: Progesterone-induced blocking factor, which is released from maternal lymphocytes during pregnancy mediates the immune effect of progesterone. According to new reports, it is suggested that proliferating cells, such as human trophoblasts, mesenchymal stem cells, and malignant tumors, can excrete progesterone-induced blocking factor at high ratio to escape from maternal immunity. It is shown in recent studies that progesterone-induced blocking factor is overexpressed in many malignant tumors such as breast, cervical, lymphoma, and leukemia...

Thiamethoxam (TMX) is a non-mutagenic neonicotinoid insecticide that is widely used to combat different types of insects. The hepatotoxicity and carcinogenicity of TMX have been approved previously in mice but not in rats. However, the TMX-induced hepatotoxic and pro-carcinogenic effects on rabbits remain unclear. The present study elucidated the roles of oxidative stress, pro-inflammatory cytokines, and apoptosis-related genes in the hepatotoxic and carcinogenic effects of TMX on rabbits. Sixteen male rabbits were equally divided into two groups; eight rabbits orally treated with TMX at a dose of 250 mg/kg b...

BACKGROUND: Non-small cell lung cancer (NSCLC) is a major cause of cancer-related death. Approximately 2-16% of NSCLC patients with wild-type epidermal growth factor receptor (EGFR) harbour anaplastic lymphoma kinase (ALK) mutations. Both EGFR and ALK mutations occur most commonly in Asian patients with NSCLC. As targeted therapy is available for NSCLC patients with these mutations, it is important to establish reliable assays and testing strategies to identify those most likely to benefit from this therapy...

Danshen (Salvia miltiorrhiza) is a traditional Chinese medicine herb that can alleviate the symptoms of osteoarthritis (OA) (Söder et al. 2006) in animals. However, the underlying mechanisms remain poorly understood and require further investigation. In this study, rabbits with experimentally induced OA were given an intra-articular injection of danshen (0.7 mL/day) for 5 weeks. In addition to attenuating the cartilage degeneration of OA in the rabbits, danshen decreased the expression and activity of matrix metalloproteinase 9 (MMP-9) and MMP-13, and increased the expression of their natural inhibitors: tissue inhibitor of matrix metalloproteinase 1 (TIMP-1) and TIMP-2...

AIMS: Neuroblastoma shows considerable histological overlap with other small round blue cell tumours. PHOX2B, a transcription factor that is essential for autonomic nervous system development, has been reported as an immunohistochemical marker for neuroblastoma. The aim of this study was to validate the specificity and diagnostic utility of PHOX2B for peripheral neuroblastic tumours. METHODS AND RESULTS: We evaluated 240 cases (133 in whole-tissue sections; 107 in tissue microarrays), including 76 peripheral neuroblastic tumours (median age 2 years; including four adults) and 164 other tumours: 44 Wilms tumours; 20 Ewing sarcomas; 10 each of CIC-rearranged round cell sarcomas, poorly differentiated synovial sarcomas, lymphoblastic lymphomas, alveolar rhabdomyosarcomas, embryonal rhabdomyosarcomas, mesenchymal chondrosarcomas, Merkel cell carcinomas, olfactory neuroblastomas, and melanomas; and five each of NUT midline carcinomas and desmoplastic small round cell tumours...

Naloxegol is an opioid antagonist which has been developed for the treatment of patients with opioid induced constipation. In the nonclinical safety program naloxegol was shown to have a very benign toxicity profile. In the rat, but not the mouse, 2-year carcinogenicity study a change in tumour pattern with an increase in testicular Leydig cell tumours (LCT) was observed after dosing at high (supra-pharmacological) concentrations. To establish the basis of the increase in LCT and to assess its potential relevance to humans, studies to exclude and potentially identify mode-of-action (MoA) were performed...

The treatment of patients with refractory/relapsed B cell non-Hodgkin lymphoma (NHL) is evolving because of the availability of novel drugs. Allogeneic stem cell transplantation (alloSCT) can be curative, but its morbidity and mortality remain a matter of concern. We conducted a multicenter prospective phase II trial to evaluate the benefit of including only 1 dose of rituximab in the conditioning regimen before alloSCT. The primary endpoint was progression-free survival. The study enrolled 121 patients with relapsed/refractory B cell lymphomas...

Kidney transplant recipients often receive antibody induction. Previous studies of induction therapy were often limited by short follow-up and/or absence of information about complications. After linking Organ Procurement and Transplantation Network data with Medicare claims, we compared outcomes between three induction therapies for kidney recipients. Using novel matching techniques developed on the basis of 15 clinical and demographic characteristics, we generated 1:1 pairs of alemtuzumab-rabbit antithymocyte globulin (rATG) (5330 pairs) and basiliximab-rATG (9378 pairs) recipients...
