Minicircle DNA vectors are plasmid derivatives free of bacterial elements. These vectors are mostly provided from common plasmids via recombination by site-specific recombinases in E. coli. Absence of bacterial backbone in minicircle vectors results in high-level and persistent expression of transgene in comparison with conventional plasmids and provides promising vehicles for gene therapy and vaccination. Here we describe the production of replicative minicircle DNA vectors using the PBAD/araC system expressing ΦC31 integrase in E...

In Special Operations Forces (SOF) closed-circuit rebreathers with 100% oxygen are commonly utilized for covert diving operations. Exposure to high partial pressures of oxygen (PO2) could cause damage to the central nervous system (CNS) and pulmonary system. Longer exposure time and higher PO2 leads to faster development of more serious pathology. Exposure to a PO2 above 1.4 ATA can cause CNS toxicity, leading to a wide range of neurologic complaints including convulsions. Pulmonary oxygen toxicity develops over time when exposed to a PO2 above 0...

Mélanie K Rich, Pierre-Emmanuel Courty, Christophe Roux, Didier Reinhardt
BACKGROUND: Development of arbuscular mycorrhiza (AM) requires a fundamental reprogramming of root cells for symbiosis. This involves the induction of hundreds of genes in the host. A recently identified GRAS-type transcription factor in Petunia hybrida, ATA/RAM1, is required for the induction of host genes during AM, and for morphogenesis of the fungal endosymbiont. To better understand the role of RAM1 in symbiosis, we set out to identify all genes that depend on activation by RAM1 in mycorrhizal roots...

INTRODUCTION: Hyperbaric oxygen (HBO₂) treatment results in elevated production of reactive oxygen species (ROS) that leads to cellular damage. Thymoquinone (TQ) is reported to have anti-inflammatory and antimicrobial activity and may suppress the generation of free radicals. The goal of this study is reduction of side effects of hyperbaric oxygen therapy with thymoquinone treatment. METHODS: 30 female Sprague-Dawley rats were randomly assigned to one of three groups (n = 10 per group)...

Hyperbaric oxygen (HBO₂) therapy is currently used for the treatment of chronic wounds, radiation-induced soft tissue necrosis, several oxygen-deficiency conditions and decompression sickness. In addition to the current indications, much empirical and experimental data suggest that HBO₂ therapy may benefit autoimmune diseases by suppressing immunity, but the underlying mechanism is not well understood. Therefore, in the present study, we investigated whether HBO₂ prevents the development of collagen-induced arthritis (CIA) in association with alteration of the immune balance between pro-inflammatory Th17 and anti-inflammatory regulatory T cells (Tregs)...

In the modern era, a pathology report of thyroid carcinoma requires the inclusion of numerous prognostically relevant histopathologic features, e.g. the presence and extent of vascular and capsular invasion, extrathyroidal extension, the surgical margin status, and the characteristics of nodal metastasis. These pathologic features are crucial components of the initial risk stratification to determine the need for completion thyroidectomy and/or post-operative radioactive iodine ablation therapy. The current review aims to summarize the diagnostic criteria, the controversies, the prognostic impacts, and the challenges of these pathologic characteristics, focusing specifically on the parameters that are incorporated into the American Joint Committee on Cancer (AJCC) staging system, College of American Pathologists (CAP) reporting template, American Thyroid Association (ATA), and National Comprehensive Cancer Network (NCCN) guidelines...

Lindell K Weaver, Kayla Deru
INTRODUCTION: The carboxyhemoglobin half-life (COHb t1/2) during hyperbaric oxygen (HBO₂) is often quoted as 23 minutes, derived from the average of two adult male volunteers breathing HBO₂ at 3 atmospheres absolute (ATA). However, the mean COHb t1/2 of 12 male volunteer smokers was 26.3 minutes at 1.58 ATA and in 12 non-intubated carbon monoxide (CO) poisoned patients treated at 3 ATA, was 43 minutes. CASE REPORT: An 81-year old male, poisoned by an improperly ventilated natural gas heater, was intubated for coma, then treated with HBO₂...

We report the case of a 54-year-old male compressed-air worker with gas bubbles detected by computed tomography (CT). He had complained of strong abdominal pain 30 minutes after decompression after working at a pressure equivalent to 17 meters of sea water for three hours. The initial CT images revealed gas bubbles in the intrahepatic portal vein, pulmonary artery and bilateral femoral vein. After the first hyperbaric oxygen treatment (HBO₂ at 2.5 atmospheres absolute/ATA for 150 minutes), no bubbles were detected on repeat CT examination...

Hyperoxic acute lung injury (HALI) is caused by prolonged exposure to high oxygen partial pressure. This study was undertaken to investigate the protective effects of oridonin on HALI in a mouse model. Mice were randomly divided into three groups: the control group, HALI group and oridonin (ORI) group. HALI was induced by exposing mice to pure oxygen at 2.5 atmospheres absolute (ATA) for six hours in the HALI and ORI groups. In the ORI group, mice were intraperitoneally injected with ORI at 10 mg/kg twice daily after hyperoxic exposure...
