The aim of this study was to examine whether flavin-containing monooxygenase (FMO) protein was expressed in cultured rat brain microvascular endothelial cells (BMECs), which constitute the blood-brain barrier (BBB), and whether N-oxide from the tertiary amine, d-chlorpheniramine, was formed by FMO in rat BMECs. BMECs were isolated and cultured from the brains of three-week-old male Wistar rats. The expression of FMO1, FMO2 and FMO5 proteins was confirmed in rat BMECs by western blotting analysis using polyclonal anti-FMO antibodies, but FMO3 and FMO4 proteins were not found in the rat BBB. Moreover, N-oxide of d-chlorpheniramine was formed in rat BMECs. The intrinsic clearance value for N-oxidation at pH 8.4 was higher than that at pH 7.4. Inhibition of N-oxide formation by methimazole was found to be the best model of competitive inhibition yielding an apparent Ki value of 0.53 μmol/L, suggesting that N-oxidation was catalyzed by FMOs in rat BMECs. Although FMO activity in rat BMECs was lower than that in SD rat normal hepatocytes (rtNHeps), we suggest that rat BMECs enzymes can convert substrates of exogenous origin for detoxification, indicating that BMECs are an important barrier for metabolic products besides hepatic cells.

Cyclic variability control is the essential way for torque generation balance,which is an important index when engine works in the steady *** paper proposes an idea for indirectly balancing cyclic variability by keeping cylinder pressure of fixed crank shift degree at its nominal *** time is chosen as the actuator after sensitive analysis is executed,and the dynamics from spark advance to cylinder pressure at the given crank shift degree is modeled,parameters are identified by using least variance algorithm,an simulation for this model is established and the PI control validated by this simulation is tested by experiments too.

We aimed to examine paracellular barrier function in cultured mouse lung microvascular endothelial cells (LMECs). The transcellular resistance of LMEC monolayers yielded an electrical resistance of approximately 19 Ω × cm2 at days 6 - 7 in culture when the cells reached confluence, and paracellular permeable clearance of sodium fluorescein was the lowest on day 6 in culture, suggesting the formation of tight junctions (TJs) in cultured LMECs. Moreover, the expression of TJ-associated proteins, occludin, claudin-1 and -4 and zonula occludents 1 (ZO-1) was detected in LMECs at day 6 in culture. However, mRNAs of occludin, claudin-1 and -4 and ZO-1 were already expressed on day 1 after culture, and large variations were absent in the mRNA levels of occludin, claudin-4 and ZO-1 between days 1 and 7 in culture, when the level of each mRNA on day 1 in culture was used as a basal level. However, the claudin-1 mRNA level gradually increased up to approximately 7-fold on day 7 in culture over the basal level. These results indicate that the drastic increase in the mRNA expression level of claudin-1 leads to the strong formation of TJs.

Hemangiolymphangioma (HL) is a congenital anomaly and histologically benign tumor, which was composed of both the lymphatic and the blood vessels. We report an adult case of HL complicated by chronic thromboembolic pulmonary hypertension (CTEPH) in a 20-year-old female. Gastrointestinal bleeding scintigraphy and operative findings elucidate a close relationship between CTEPH and residual HL. This case indicates that HL survivors with remaining left-to-right shunt might lead to CTEPH during the long-term follow-up.

Aim: To clarify the factors associated with reported dietary fat intake by Japanese male children. Methods: This study is based on the data of a nationally representative cross-sectional study in Japan. Three hundred and seventy-seven male children (age, 6 - 11 years) whose households were sampled in the 1995 Comprehensive Survey of Living Conditions of the People on Health and Welfare, and the 1995 National Nutrition Survey and whose parents were identified through record linkage between the 2 survey data sets were enrolled. Results: The final dataset in this study consisted of 377 boys with 329 of their parents. Fifty-two boys were found to be overweight (13.8%). The reported dietary fat intake was higher among the overweight boys than among the non-overweight boys. Maternal obesity was significantly associated with obesity in male children. Boys who frequently consumed foods from the “fats and lipids” group and the “meat” groups, and children from nuclear families rather than 3- generation families reported high dietary fat intake. In addition, parental fat intake was also significantly associated with fat intake of male children. Conclusions: Child and parental dietary habits along with the household status should be considered when implementing nutritional education programmes to control dietary fat intake and reduce the obesity risks of male children.
