The area of travel demand analysis has in recent years been greatly enriched by the development of new model forms that can accommodate complex patterns of substitution and taste variation. However, this added flexibility comes at a cost of greater complexity in estimation, to the degree that these models need to be estimated through simulation. While basic Monte-Carlo integration can lead to a...

Polymorphonuclear cells of the peripheral blood in the chicken significantly increased their phagocytosis when cultured with sugar cane extract (SCE; 250-1,000 microg/ml) for 24 hr. Chickens orally administered SCE (500 mg/kg/day) for 3 or 6 consecutive days at 1 week of age showed significantly higher body weight and gain in body weight/day and a lower food conversion ratio within the growing ...

The dynamic weapon target assignment (DWTA) problem is of great significance in modern air combat. However, DWTA a highly complex constrained multi-objective combinatorial optimization problem. An improved elitist non-dominated sorting genetic algorithm-II (NSGA-II) called the shuffled frog leaping algorithm (NSFLA) proposed to maximize damage enemy targets and minimize self-threat combat const...

Previously, we observed that the demethylating agent 5-azacytidine (azaC) induces a constant and limited low frequency of sister chromatid exchange (SCE), seemingly due to a limited number of SCE-prone sites whose expression is related to DNA demethylation. An alternative explanation for the low frequency of SCE induction may be its inefficient incorporation into DNA, as it has a higher incorpo...

The induction of sister chromatid exchanges (SCE) by the hepatocarcinogen methapyrilene hydrochloride was investigated using appropriate in vitro and in vivo mammalian cell systems. Methapyrilene, even at the maximum tolerated dose, did not induce SCE in Chinese hamster ovary cells (CHO) or when CHO cells or hamster lung fibroblasts, V-79, were cocultivated with early cultures of rat liver epit...

Stellera chamaejasme L. (Thymelaeaceae) is a perennial herb that is widely used in traditional Chinese medicine to treat tumours, tuberculosis and psoriasis. S. chamaejasme extract (SCE) possesses anti-inflammatory, analgesic and wound healing activities; however, the effect of S. chamaejasme and its active compounds on cutaneous wound healing has not been investigated. We assessed full-thickne...

The potential hair growth-promoting activity of rice bran supercritical CO2 extract (RB-SCE) and major components of RB-SCE, linoleic acid, policosanol, γ-oryzanol, and γ-tocotrienol, were evaluated with the histological morphology and mRNA expression levels of cell growth factors using real-time reverse transcriptase-polymerase chain reaction (PCR) in C57BL/6 mice. RB-SCE showed hair growth-pr...

PURPOSE Non-steroidal anti-inflammatory drugs (NSAID) are frequently used in oral surgical procedures in dentistry. The evaluation of the frequency of sister chromatid exchange (SCE) is accepted as a reliable cytogenetic method to assess the genotoxic effects of environmental factors. MATERIALS AND METHODS In this study, the genotoxic effects of various NSAIDs were assessed in 30 patients to ...
