Notch signalling pathways mediate synovial angiogenesis in response to vascular endothelial growth factor and angiopoietin 2.
Notch signalling pathways are critical for angiogenesis and endothelial cell (EC) fate; however the mechanisms regulating these processes in the inflamed joint remain to be elucidated. Here, we examine whether Notch signalling mediates vascular endothelial growth factor (VEGF) and angiopoietin 2 (Ang2)-induced vascular...

Rate dependent effects of acute nicotine on risk taking in young adults are not related to ADHD diagnosis.
Beneficial effects of nicotine on cognition and behavioral control are hypothesized to relate to the high rates of cigarette smoking in Attention-Deficit/Hyperactivity Disorder (ADHD). Given that ADHD is associated with both impulsivity and elevated risk taking, we hypothesized that nicotine modulates risk taking, as i...

Body fat distribution in relation to smoking and exogenous hormones in British women.
&#x2002;Both cigarette smoking and use of exogenous hormones are associated with changes in regional distribution of body fat, but their combined effects are less investigated. We examined the interrelation between smoking, exogenous hormones and fat distribution in premenopausal and postmenopausal women.</AbstractText...

Histone deacetylase activity selectively regulates notch-mediated smooth muscle differentiation in human vascular cells.
Histone deacetylases (HDACs) modify smooth muscle cell (SMC) proliferation and affect neointimal lesion formation by regulating cell cycle progression. HDACs might also regulate SMC differentiation, although this is not as well characterized.</AbstractText>Notch signaling activates SMC contractile markers and the diffe...

Mathematical modeling of upflow anaerobic sludge blanket (UASB) reactor treating domestic wastewater.
Although the upflow anaerobic sludge blanket (UASB) reactor has been widely applied for domestic wastewater treatment in many developing countries, there is no sufficient mathematical model for proper design and operation of the reactor. An empirical model based on non-linear regression was developed to represent the p...

Bioconversion characteristics of Rhodopseudomonas palustris CQK 01 entrapped in a photobioreactor for hydrogen production.
The performance of the entrapped-cell photobioreactor during H2 production was assessed by using glucose as substrate in a continuous operation mode. The maximal hydrogen production rate and light conversion efficiency, 2.61 mmol/L/h and 82.3%, were obtained at a HRT of 11.4 h, an substrate loading rate of 4.2 mmol/h a...

The anticancer agent YC-1 suppresses progestin-stimulated VEGF in breast cancer cells and arrests breast tumor development.
Recent epidemiological studies show that postmenopausal women taking estrogen-progestin hormone replacement therapy (HRT) have a higher risk of breast cancer than women on an HRT regimen lacking progestins. This may be related to the observation that progestin-treated breast cancer cells express and secrete high levels...
