The title compound, C(14)H(20)O(3), is a synthetic analogue with a long aliphatic side chain of the important food additive and flavoring agent, vanillin. There are two independent mol-ecules in the asymmetric unit, each having an essentially planar conformation (r.m.s. deviations of 0.023 and 0.051Å for all non-H atoms of the two mol-ecules in the asymmetric unit).

Pain is a significant clinical problem, and there is a need for more effective treatments with reduced adverse effects that currently limit the use of μ opioid receptor agonists. Synthetic κ opioid receptor agonists have no abuse liability and well-documented antinociceptive effects; however, adverse effects (diuresis, dysphoria) preclude their use in the clinic. Combining κ opioids with nonopi...

BACKGROUND Recently, the presence of an unauthorized genetically modified (GM) Bacillus subtilis bacterium overproducing vitamin B2 in a feed additive was notified by the Rapid Alert System for Food and Feed (RASFF). This has demonstrated that a contamination by a GM micro-organism (GMM) may occur in feed additives and has confronted for the first time,the enforcement laboratories with this typ...

objective: carthamus tinctorius l. (safflower) is a member of the asteraceae family which is used as a food additive but also has medicinal applications. this study investigated its effects on placental histomorphology and survival of mice neonates. materials and methods: eighty balb/c pregnant mice were randomly distributed into one control and three experimental groups (n=20). the control gro...

This article introduces an efficient, low cost, and clean (zero pollution) zone melting phosphorus purification technique. We have successfully removed arsenic from solid phosphorus by melting a narrow region and making the resulting liquid zone travel slowly through a relatively long ingot of phosphorus. This technique can reduce arsenic concentration in solid phosphorus from 100 ppm to 10 ppm...

The food industry is a business of mass production and consumption. Plants and animals that are grown in bulk in farmlands nationwide are processed later at large factories. It is no surprise that some of the most popular snack foods have a lengthy list of ingredients. The various chemicals found in food serve to enhance the color, texture, flavor, and shelf life. There are hundreds of food add...

Research reflects that true food allergy affects 6-8% of infants, 3-5% of young children and 2-4% of adults. This incidence has rapidly increased over the last 25 years. Nut allergies which were first documented in the early 1980s are now very common, while the incidence of cow’s milk allergy seems to have reached a plateau. As our eating habits change and we become exposed to more exotic foods...

Nepeta cataria L. is traditionally consumed as a food additive. The effects of three different harvest stages of N. cataria essential oils (EOs) against most common causes of food-borne infections were evaluated by broth microdilution method as recommended by the Clinical and Laboratory Standards Institute (CLSI). The chemical composition of the EOs from N. cataria has been analyzed by gas chro...

Seronegative spondilo-arthropathies are characterized by particular clinical features such as sacroileitis, spondylitis and asymmetric peripheral arthritis mainly involving the lower limbs and negative rheumatoid factor. In most cases, they are associated with the HLA class I antigen B 27 (1). We have recently reported that in few selected cases of seronegative arthritis, articular symptoms may...
