Abstract
The transcription factor Sox2 is necessary for foregut morphogenesis. Sox2 is also required for the normal development of the trachea and lung. Recently, Sox2 amplifications were investigated using large-scale single nucleotide polymorphism arrays in esophageal and lung cancer. We hypothesized that Sox2 overexpression might be correlated with clinicopathological features of lung cancers. The increased copy number of the Sox2 gene was analyzed by real-time polymerase chain reaction amplifications in 127 surgically treated non-small cell lung cancer cases from Nagoya City University Hospital, Japan. A total of 87 squamous cell carcinoma (SCC) cases were involved. An increased Sox2 gene copy number was found in 42 (33.1%) lung cancer patients. Increased Sox2 copy number status was significantly correlated with gender (females, 9.5% vs. males, 34.1%; p=0.0026), smoking status (never smoker, 4.8% vs. smoker, 32.9%; p=0.0003) and pathological subtypes (squamous cell carcinoma, 44.8% vs. non-squamous cell carcinoma, 7.5%; p<0.0001). However, among the SCCs, the Sox2 copy number status was not significantly correlated with gender, smoking status, pathological stage or differentiation status. An increased Sox2 copy number is common within SCC.

Abstract
Root nodule (RN) symbiosis has a unique feature in which symbiotic bacteria fix atmospheric nitrogen. The symbiosis is established with a limited species of land plants, including legumes. How RN symbiosis evolved is still a mystery, but recent findings on legumes genes that are necessary for RN symbiosis may give us a clue.

Abstract
The transfer of part of the ulnar nerve to the musculocutaneous nerve, first described by Oberlin, can restore flexion of the elbow following brachial plexus injury. In this study we evaluated the additional benefits and effectiveness of quantitative electrodiagnosis to select a donor fascicle. Eight patients who had undergone transfer of a simple fascicle of the ulnar nerve to the motor branch of the musculocutaneous nerve were evaluated. In two early patients electrodiagnosis had not been used. In the remaining six patients, however, all fascicles of the ulnar nerve were separated and electrodiagnosis was performed after stimulation with a commercially available electromyographic system. In these procedures, recording electrodes were placed in flexor carpi ulnaris and the first dorsal interosseous. A single fascicle in the flexor carpi ulnaris in which a high amplitude had been recorded was selected as a donor and transferred to the musculocutaneous nerve. In the two patients who had not undergone electrodiagnosis, the recovery of biceps proved insufficient for normal use. Conversely, in the six patients in whom quantitative electrodiagnosis was used, elbow flexion recovered to an M4 level. Quantitative intra-operative electrodiagnosis is an effective method of selecting a favourable donor fascicle during the Oberlin procedure. Moreover, fascicles showing a high-amplitude in reading flexor carpi ulnaris are donor nerves that can restore normal elbow flexion without intrinsic loss.

Abstract
Algal blooms in eutrophic water bodies are controlled by inputs of phosphorus (P) as the growth-limiting nutrient. Runoff particulate P associated with soil from fields often predominates among P fractions. Here, an algal bioassay to investigate the potential bioavailability of particulate P in soil collected from a citrus orchard was conducted. Microcystis aeruginosa was cultured in medium containing soil as the sole source of P. The P in the soil was not notably solubilized after autoclaving. Analyses of chlorophyll-a, suspended solids, particulate organic carbon, and particulate organic nitrogen showed that M. aeruginosa could utilize some of the P present in the soil, perhaps that in particulate form, but this form of P was not sufficient to maintain optimum growth.

Abstract
Maggot debridement therapy (MDT) is a method for the treatment of intractable, infected and necrotic wounds. In MDT, sterile larvae of Lucilia sericata Meigen (Diptera: Calliphoridae) are applied to infected wounds, where they exert antibacterial effects. Once the larvae are placed in the wound, they are no longer germ-free. This study analysed the influence of infected environments on larval antibacterial activities. Sterile larvae were mixed in a test tube containing a bacterial suspension of Staphylococcus aureus or Pseudomonas aeruginosa, transferred to liver puree agar, and incubated at 25 °C for set periods. To collect the larval extracts, the incubated larvae were transferred to a test tube containing phosphate buffered saline (PBS), cut into multiple pieces with scissors, and centrifuged. The supernatant was used to test antibacterial activities. The results showed that infected larvae had better antibacterial capacities than sterile larvae. Antibacterial activities were induced by pretreatment with a single bacterial species, S. aureus or P. aeruginosa, within 24 h and 12 h, respectively, and disappeared after 36 h. The activities were effective against S. aureus, but not against P. aeruginosa. This natural infection model is very similar to the clinical wound context in MDT and will be a powerful tool with which to study the antibacterial activities of L. sericata larvae in MDT.

Abstract
Great advances have been made in our understanding of the host plant's common symbiosis functions, which in legumes mediate intracellular accommodation of both nitrogen-fixing bacteria and arbuscular mycorrhiza (AM) fungi. However, it has become apparent that additional plant genes are required specifically for bacterial entry inside the host root. In this opinion article, we consider Lotus japonicus nap1 and pir1 symbiotic mutants within the context of other deleterious mutations that impair an intracellular accommodation of bacteria but have no impact on the colonization of roots by AM fungi. We highlight a clear delineation of early signaling events during bacterial versus AM symbioses while suggesting a more intricate origin of the plant's ability for intracellular accommodation of bacteria.

Abstract
Helicobacter pylori (H. pylori) is a predominant pathogen that causes not only gastroduodenal diseases but also extra-alimentary tract diseases. In this study, we demonstrated that H. pylori infection promoted atherogenesis in heterozygous apoe(+/ --) ldlr(+/--) mice. The male mice were fed with high fat diet from the age of 6 weeks. At the age of 16 weeks, development of atherosclerotic lesions was observed in the H. pylori-infected mice, and it seemed to be associated with an elevation of Th1-immune response against H. pylori origin-heat shock protein 60 (Hp-HSP60) and an increment of transendothelial migration of T cells. Subcutaneous immunisation with Hp-HSP60 or H. pylori eradication with antibiotics significantly reduced the progression of atherosclerosis, accompanied by a decline of Th1 differentiation and reduction of their chemotaxis beyond the endothelium. Thus, oral infection with H. pylori accelerates atherosclerosis in mice and the active immunisation with Hp-HSP60 or the eradication of H. pylori with antibiotics can moderate/prevent cellular immunity, resulting in a reduction of atherosclerosis.

Abstract
Infection thread-dependent invasion of legume roots by rhizobia leads to internalization of bacteria into the plant cells, which is one of the salient features of root nodule symbiosis. We found that two genes, Nap1 (for Nck-associated protein 1) and Pir1 (for 121F-specific p53 inducible RNA), involved in actin rearrangements were essential for infection thread formation and colonization of Lotus japonicus roots by its natural microsymbiont, Mesorhizobium loti. nap1 and pir1 mutants developed an excess of uncolonized nodule primordia, indicating that these two genes were not essential for the initiation of nodule organogenesis per se. However, both the formation and subsequent progression of infection threads into the root cortex were significantly impaired in these mutants. We demonstrate that these infection defects were due to disturbed actin cytoskeleton organization. Short root hairs of the mutants had mostly transverse or web-like actin filaments, while bundles of actin filaments in wild-type root hairs were predominantly longitudinal. Corroborating these observations, temporal and spatial differences in actin filament organization between wild-type and mutant root hairs were also observed after Nod factor treatment, while calcium influx and spiking appeared unperturbed. Together with various effects on plant growth and seed formation, the nap1 and pir1 alleles also conferred a characteristic distorted trichome phenotype, suggesting a more general role for Nap1 and Pir1 in processes establishing cell polarity or polar growth in L. japonicus.

Abstract
In this study, we investigated the function of a putative high-molecular-weight outer membrane protein, azorhizobial outer membrane autotransporter A (AoaA), of Azorhizobium caulinodans ORS571. Sequence analysis revealed that AoaA was an autotransporter protein belonging to the type V protein secretion system. Azorhizobium caulinodans forms N(2)-fixing nodules on the stems and roots of Sesbania rostrata. The sizes of stem nodules formed by an aoaA mutant having transposon insertion within this ORF were as large as those in the wild-type strain, but the N(2)-fixing activity of the nodules by the aoaA mutant was lower than that of wild-type nodules. cDNA-amplified fragment length polymorphism and reverse transcriptase-PCR analysis revealed that the expressions of several pathogen-related genes of host plants were induced in the aoaA mutant nodules. Furthermore, exopolysaccharide production was defective in the aoaA mutant under free-living conditions. These results indicate that AoaA may have an important role in sustaining the symbiosis by suppressing plant defense responses. The exopolysaccharide production controlled by AoaA might mediate this suppression mechanism.

Abstract
We investigated the association of smoking, atopy and helper T (Th) cytokines with sensitization to methyltetrahydrophthalic anhydride (MTHPA) in occupationally exposed subjects. A population of 147 workers from two condenser plants using epoxy resin with MTHPA underwent a questionnaire survey and serologic investigation. Total and MTHPA-specific IgE levels were measured by the Pharmacia CAP system, and serum levels of interleukin (IL)-4, IL-13, and interferon-gamma (IFN-g) by enzyme immunoassay. The Pharmacia CAP-Phadiatop test, which detects serum IgE specific to most common aeroallergens, was also used. Ninety-six (65%) of the currently exposed workers had positive MTHPA-specific IgE. A significant difference was found in the frequency of positive specific IgE between atopic and non-atopic subjects (P<0.01), but not between smokers and non-smokers. As for smoking, the frequency of positive specific IgE was significantly (P<0.005) higher in smokers than that in non-smokers in non-atopic subjects. Multiple logistic regression analysis also confirmed significant contribution of atopy and smoking to the development of specific IgE (odds ration=3.2 and 10.5, respectively), suggesting that atopic subjects who became sensitized to P<0.01 may become sensitized to common aeroallergens. On the other hand, none of the Th cytokines contributed to the elevation of specific IgE levels. These results suggest that atopic subjects and non-atopic smokers are at increased rist of sensitization by P<0.01. However, to evaluate conclusively the effect of atopy on sensitization, further prospective studies are necessary.

Abstract
Eleven strains of Clostridium butyricum collected from different sources were analysed by both sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and pulsed-field gel electrophoresis (PFGE). The strains could be classified into four groups based on their banding profiles of the proteins extracted from the cells on SDS-PAGE. Group I consisted of seven strains, and these strains were further divided into five subgroups by PFGE. The strains belonging to groups II, III, and IV on SDS-PAGE were also classified into the same II to IV groups by PFGE. These data indicate that grouping of the strains of C. butyricum can be performed by employing both SDS-PAGE and PFGE.

Abstract
We report a patient with epidermodysplasia verruciformis (EV) who had severe generalized verrucous skin lesions for 50 years without any immunological abnormality. Microscopic examination showed two histopathological features, including seborrhoeic keratosis and common warts. The detected human papilloma virus (HPV) types were found to be HPV 3, 50, 5, and 76, using a degenerate PCR method. EV and generalized verrucosis are distinguished by slight differences in clinical symptoms or HPV types, so there should be no apparent differential points common to both diseases. Therefore, we propose that an abnormal susceptibility specific to HPV, which is the most characteristic feature in EV, should be regarded as a differential point in these two diseases.

Abstract
We report five consecutive cases of neuraxial anesthesia for cesarean section in women with moyamoya disease. Either epidural or combined spinal-epidural anesthesia was provided, with adequate sedation using intravenous diazepam and/or opioid(s). Hemodynamic stability and normocapnia were well maintained, except in one patient who exhibited transient hypertension and hypocapnia due to anxiety. None of the parturients suffered from neurological deficit in the intra- or postoperative period, although one patient complained of numbness in her fingers at the end of surgery, but she was not hypotensive or hypocapneic. The neonates were all in good health. The literature is reviewed on the anesthetic management for cesarean section in patients with moyamoya disease.
