Quality control of plant food supplements
It is essential to guarantee the safety of unprocessed plants and food supplements if consumers' health is to be protected. Although botanicals and their preparations are regulated at EU level, at least in part, there is still considerable discretion at national level, and Member States may choose to classify a product either as a food supplement or as a drug. Accurate data concerning the finished products and the plant used as the starting point are of major importance if risks and safety are to be properly assessed, but in addition standardized criteria for herbal preparation must be laid down and respected by researchers and manufacturers. Physiologically active as well as potentially toxic constituents need to be identified, and suitable analytical methods for their measurement specified, particularly in view of the increasing incidence of economically motivated adulteration of herbal raw materials and extracts. It remains the duty of food operators to keep up with the scientific literature and to provide sufficient information to enable the adaptation of specifications, sampling schemes and analytical methods to a fast-changing environment
Free amino acid content in standard infant formulas: comparison with human milk
To compare the concentration of non-protein nitrogen (NPN) and free amino acids (FAA) in powdered and liquid commercial formulas with that in human milk
The role of testosterone on the sleep related penile erections
In order to identify a possible threshold for a serum testosterone level below which sleep-related erections are impaired and to compare this threshold with the normal laboratory range of testosterone serum levels, we studied hypogonadal and eugonadal subjects by means of Rigiscan, a tool useful to monitor penile tumescence and rigidity during sleep
Free glutamine and glutamic acid increase in human milk through a three-month lactation period
Previous short observational studies on the free amino acid (FAA) content of human milk have shown that glutamine and glutamic acid increase in the first 4 to 6 weeks of life
