The acute toxic effect of different crude oils (heavy crude oil and bonny light crude oil) on embryos of marine medaka Oryzias melastigma was measured and evaluated by exposure to the water-accommodated fraction (WAF) in the present study. The cardiac function of medaka embryos was used as target organ of ecotoxicological effect induced by oil exposure. Results showed that the developing marine...

BACKGROUND Hydrolysis of the fruit phenolic glucosides occurring during oil extraction process is main biochemical reaction affecting biosynthesis and accumulation secoiridoid compounds in virgin olive oil. An integrated approach at molecular, biochemical, metabolic level was used to study ?-glucosidase gene family seven cultivars selected by their different profiles. RESULTS Eight genes have b...

Advanced glycation end products (AGEs) have been implicated in the accelerated vascular injury occurring in diabetes. We recently reported that LDL prepared from type 2 diabetic patients (dm-LDL), but not normal LDL (n-LDL) triggered signal transducers and activators of transcription STAT5 activation and p21(waf) expression in endothelial cells (ECs). The aims of the present study were to inves...

Cell cycle checkpoints ensure orderly progression of events during cell division. A microtubule damage (MTD)-induced checkpoint has been described in G(1) phase of the cell cycle (G(1)MTC) for which little is known. The present study shows that the G(1)MTC is intact in activated T lymphocytes from mice with the p21(waf-1) gene deleted. However, p21(waf-1) gene deletion does affect the ratio of ...

Diamond-like carbon (DLC) and silicon carbide (SiC) coatings are attractive because of low friction coefficient, high hardness, chemical inertness and smooth finish, which they provide to biomedical devices. Silicon wafers (Si(waf)) and silicone rubber (Si(rub)) plates were coated using plasma-enhanced chemical vapour deposition (PE-CVD) techniques. This article describes: 1- the characterizati...

Recently, Dunne et al. [9,10] introduced the concept of WAF (Weighted Argumentation Framework). Such frameworks extend standard Dung’s ones for abstract argumentation by associating weights with attacks. In the WAF setting, weights are used for relaxing extensions, which proves useful when there are too few extensions. In this paper, we exploit weights in a different perspective. We show how to...

Because of its surface characteristics, once in the aquatic environment, graphene could act as a carrier pollutants, such polycyclic aromatic hydrocarbons (PAHs), to organisms. In this study we aimed (1) assess capacity oxide (GO) sorb PAHs and (2) evaluate toxicity GO alone combination with on zebrafish embryos adults. showed high sorption for benzo(a)pyrene (B(a)P) (98% B(a)P sorbed from nomi...

Web applications represent one of the principal vehicles by which attackers gain access to an organization’s network or resources. Thus, different approaches protect web have been proposed date. Of them, two major areWeb Application Firewalls (WAF) and Runtime Self Protection (RASP). It is, thus, essential understand differences relative effectiveness both these for effective decisionmaking reg...
