Water strider Aquarius paludum （Fabricius） is a cosmopolitan species colonizes mainly freshwater but occasionally brackish habitats throughout the Palearctic and Oriental regions. Water strider Gerris latiabdominis （Miyamoto） is a common species in Japan lives in temporary habitats as freshwater paddy fields. These two species often occur syntopically. We investigated differences in the developmental response to brackish water during embryonic and larval stages between the two species. Eggs were exposed to 0-1.8% NaC1 solutions within 24 h of oviposition. Larvae of G. latiabdominis were exposed to salinities of 0, 0.5%, and 0.9% from the first instar until adult emergence. Limits of NaC1 concentration for hatching were 1.3% and 1.0% for A. paludum and G. latiabdominis, respectively. The hatching rate of G. latiabdominis was lower than that ofA. paludum at salinities 〉0.9%. The period of embryonic development of G. latiabdominis was more prolonged than that ofA. paludum at a given salinity. Although the salinity tolerance of G. latiabdominis was lower than that ofA. paludum, our results suggest G. latiabdominis has the physiological capacity to expand into brackish waters. High and low salinity tolerances of A. paludum and G. latiabdominis, respectively, reflect the relatively wide range of habitat salinities utilized by A. paludum and the relatively restricted habitats preferred by G. latiabdominis. The high salinity tolerance ofA. paludum could be an important factor contributing to their cosmopolitan distribution because high tolerance to salinity means the possibility of them to be dispersed via ocean or sea to other continents and islands.

The influences of DC and AC electric fields,at frequencies up to 1.48 MHz and the maximum strength of about 6 kV/cm,on soot formation and flame structure were investigated using a counterflow type acetylene diffusion *** distributions of flame luminosity,soot volume fraction,flame temperature and OH concentration in flame were measured by non-invasive detection methods. Under the influence of electric fields,the changes in distribution of the soot volume fraction were confirmed. Electric fields of high frequency and high intensity reduced the soot volume fraction,whereas other electric fields increased *** maximum values of flame temperature and OH concentration decreased. In the relationship between the maximum value of the soot volume fraction and the maximum temperature,the maximum soot volume fraction showed both increase and decrease with maximum temperatures depending on the frequencies and intensities of the electric fields,and both of them occurred at temperatures lower than 1900 *** production of the incipient particles seemed to be the dominant process controlling the soot volume fraction due to the electric *** luminosity of a sooting diffusion flame was found to depend on the volume fraction and temperature of the soot particles in the *** for the behavior of the flame in the electric fields,the ionic wind effect was not found to be dominant in the present work,and the result of the previous simulation based on the ionic wind theory was not consistent with the present experimental results.

Anchovy （Engraulis aponicus）, a small pelagic fish and food of other economic fishes, is a key species in the Yellow Sea ecosystem. Understanding the mechanisms of its recruitment and biomass variation is important for the prediction and management of fishery resources. Coupled with a hydrodynamic model （POM） and a lower trophic level ecosystem model （NEMURO）, an individual-based model of anchovy is developed to study the influence of physical environment on anchovy＇s biomass variation, Seasonal variations of circulation, water temperature and mix-layer depth from POM are used as external forcing for NEMURO and the anchovy model. Biomasses of large zooplankton and predatory zooplankton which anchovy feeds on are output from NEMURO and are controlled by the consumption of anchovy on them. Survival fitness theory related to temperature and food is used to determine the swimming action of anchovy in the model. The simulation results agree well with observations and elucidate the influence of temperature in over-wintering migration and food in feeding migration.

AIM: To investigate whether the pro- and anti-inflammatory cytokine gene polymorphisms, IL1B-511C/T, IL1B-31C/T, IL6-634C/G, TNF-1031T/C, TNF-857C/T, and IL10-1082A/G, interact with smoking and drinking habits to influence infection with H ***: The subjects were 410 Japanese transit company employees. C-reactive protein and conventional cardiovascular risk factors were evaluated. Serum anti-H pylori antibodies were measured. The genotypes of IL1B-511C/T, IL1B-31C/T, IL6-634C/G, TNF-1031T/C, TNF-857C/T, and IL10-1082A/G polymorphisms were determined by allelic discrimination using fluorogenic probes and a 5′nuclease ***: In gender- and age-adjusted logistic analyses, the subjects with TNF-857T/T had a significantly lower odds ratio (OR) for H pylori seropositivity (reference -857C/C; OR = 0.15, 95% CI: 0.03-0.59, P = 0.007). After stratification according to smoking and drinking status, among never-smokers, the subjects with IL1B-511C/T had a significantly lower OR (reference -511C/C; OR = 0.30, 95% CI: 0.10-0.90, P = 0.032). Among drinkers in the 1-5 times/wk category, the subjects with IL1B-511T/T had a significantly lower OR (reference C/C; OR = 0.38, 95% CI: 0.16-0.95, P = 0.039), and the subjects with IL1B-31C/T and T/T had a significantly higher OR (reference C/C; C/T: OR = 2.59, 95% CI, P = 0.042: 1.04-6.47; C/C: OR = 3.17, 95% CI: 1.23-8.14, P = 0.017). Among current smokers, the subjects withIL6-634C/G had a significantly higher OR (reference C/C; OR = 2.28, 95% CI: 1.13-4.58, P = 0.021). However, the interactions terms between the aforementioned genotypes and lifestyles were not statistically ***: Contrary to previous findings, the results herein suggest that the TNF-857T/T genotype may be protective against chronic infection with H pylori. Drinking and smoking habits may influence the effect of cytokine gene polymorphisms. Further studies are required to clarify the effects of the pro- and anti-inflammatory cytokine

Background Osteoarthritis （OA） is a chronic and incurable disease, lacking effective treatment. Gene therapy offers a radical different approach to the treatment of arthritis. Even though the etiology of OA remains unclear, there is now considerable evidence to suggest that interleukin-1 （IL-1） and tumor necrosis factor- α （TNF- α ） are the main mediators in the pathogenesis of OA. The goal of this study was to determine the efficacy of local expression of interleukin-1 receptor antagonist （IL-1Ra） and soluble tumor necrosis factor- α receptor type Ⅰ （sTNF-RI） by direct adenoviral-mediated intra-articular gene delivery in the rabbit model of osteoarthritis. Methods Adenoviral vectors containing IL-1Ra or sTNF-RI genes were constructed. OA was induced in both hind knees of 12 New Zealand white rabbits by the excision of the medial collateral ligament plus medial meniscectomy. Five days after surgery, approximately 1 × 10^8 plaque-forming units （pfu） of adenovirus were injected into the joint space of the knee through the patellar tendon. A total of 12 operated rabbits were divided into four groups. Three experimental rabbit groups received 1 × 10^8 pfu of adenovirus encoding either IL-1Ra （3 rabbits）, sTNF-RI （3 rabbits） or IL-1Ra and sTNF-RI in combination （3 rabbits）, into both knee joints respectively. An inflamed control group of 3 rabbits received approximately 1 × 10^8 pfu of Ad-GFP into both joints. Three days after injection of the adenovirus, both knees of each rabbit were lavaged with 1 ml of saline solution through the patellar tendon. At day 7, the rabbits were sacrificed, and the knees were lavaged, dissected and analyzed for effects of transgene expression. Levels of IL-1Ra and sTNF-RI expression in recovered lavage fluids were measured using a cytokine ELISA kit. Cartilage from the lesion areas of medial femoral condyle and synovium were fixed, embedded, sectioned and stained with hematoxylin and eosin （cartilage and synovium） and toluidine blue （car
