The inhibition effect of rapid variations pH in wastewater on activated sludge was investigated laboratory-scale sequencing batch reactors (SBR). toxic influence 6.5 and 8.5 examined. experiment with preferable to formation high FA concentration showed a low risk second step nitrification (conversion nitrites nitrates). However, the reactor at first-step ammonia nitrites) caused by FNA formatio...

We tested the hypothesis that angiotensin II (Ang II)-induced stimulations of endothelin (ET) and isoprostanes are implicated in the slow pressor responses to Ang II. We infused either vehicle (group 1) or Ang II (groups 2 to 4) intravenously at 5 ng/kg per minute via osmotic pumps for 15 days into Sprague-Dawley rats. Groups 3 and 4 received 30 mg/kg per day of either losartan (Ang II type 1 r...

It has been reported that growth hormone (GH)-releasing peptide-2 (GHRP-2), a ghrelin receptor agonist, has an anti-inflammatory effect. We investigated whether this GH secretagogue attenuates liver injury in LPS-treated rats. Wistar rats were simultaneously injected (ip) with LPS (1 mg/kg) and/or GHRP-2 (100 microg/kg). Serum levels of aspartate and alanine transaminases were measured as an in...

The results of French intake estimates for 13 food additives prioritized by the methods proposed in the 2001 Report from the European Commission on Dietary Food Additive Intake in the European Union are reported. These 13 additives were selected using the first and second tiers of the three-tier approach. The first tier was based on theoretical food consumption data and the maximum permitted le...

Inevitably, reading is one of the requirements to be undergone. To improve the performance and quality, someone needs to have something new every day. It will suggest you to have more inspirations, then. However, the needs of inspirations will make you searching for some sources. Even from the other people experience, internet, and many books. Books and internet are the recommended media to hel...

BACKGROUND Studies have suggested that nitrates, nitrites, and nitrosamines have an etiologic role in adverse pregnancy outcomes and chronic diseases such as cancer. Although an extensive body of literature exists on estimates of these compounds in foods, the extant data varies in quality, quantified estimates, and relevance. METHODS We developed estimates of nitrates, nitrites, and nitrosami...

BACKGROUND Tobacco smoking and alcohol abuse causes oxidative stress in humans and underlay numerous chronic degenerative diseases. Liver is the main organ exposed to alcohol toxic metabolites, whereas tobacco smoke is chiefly harmful to the lungs. METHODS The aim of the current study was the assessment and comparison of selected oxidative stress markers, reduced glutatione (GSH), glutathione...
