urban horticulture is of growing importance in developing and developed countries around the world; however, contamination of urban horticultural products can exceed the precautionary values, posing significant human health risks due to dietary exposure to high levels of the pollutants. in this study, samples of rhizosphere soil and corresponding vegetables have been collected from an urban gar...

Most of the drugs that are available in the marketplace are administered via the oral route, which is a convenient and cost effective route of administration (Lipinski 1995; Lipinski 2000; Lipinski et al. 2001; Lipinski 2004; Abrahamsson and Lennernas 2005). Thus, oral bioavailability is one of the key considerations for discovery and development of a new chemical entity (NCE). It is well recog...

The influence of fatty diet and standard diet on the bioavailability and plasma half life of conventional theophylline was studied in the rabbit. It was found that standard diet had significantly reduced the extent of oral bioavailability (AUC0-alpha) of theophylline compared to the fasting state. The fatty diet resulted in a significantly increased extent of oral bioavailability (AUC0-alpha an...

A low Omega-3 Index (eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in erythrocytes) is associated with cardiac, cerebral, and other health issues. Intake of EPA and DHA, but not of alpha-linolenic acid (ALA), increases the Omega-3 Index. We investigated bioavailability, safety, palatability and tolerability of EPA and DHA in a novel source: a variety of sausages. We screened 96 hea...

The intestinal absorption of folate occurs at the monoglutamyl level, and an important measure of food folate bioavailability is how much folate from the food reaches the intestinal sites in forms that can readily be absorbed. In the absence of protecting agents, e.g., vitamin C and reduced thiols, many labile folates may be lost during cooking and during residence in the acid-peptic milieu of ...

Plasma concentration-time data after oral and intravenous administration of dexamethasone have been subjected to pharmacokinetic analysis in six neurological or neurosurgical patients taking the steroid with phenytoin, and in nine patients (one studied twice) taking dexamethasone without phenytoin. An additional patient was studied before and during phenytoin intake. Apparent volume of distribu...

Iron bioavailabilities and antioxidant activities of 3 generic raisin types—Golden Thompson, Dipped Thompson, and Sun-dried Thompson—were quantified and compared. Iron bioavailability was assessed with an in vitro digestion/Caco-2 cell culture model using cell ferritin formation as an index of iron bioavailability. Antioxidant activity was determined using the total oxyradical-scavenging capaci...

Rosuvastatin is a lipid lowering agent, which has low solubility and low bioavailability of 20% with oral administration. Therefore the present study was undertaken to improve solubility and bioavailability of Rosuvastatin by formulating it into Nano structured lipid carriers (NLCs) by using stearic acid and Compritol ATO 888 as solid-lipid, Oleic acid as liquid-lipid and Poloxamer 188 as a sur...
