The U.S. Food and Drug Administration today announced a final rule establishing regulations to require current good manufacturing practices (cGMP) for dietary supplements. The rule ensures that dietary supplements are produced in a quality manner, do not contain contaminants or impurities, and are accurately labeled.

"This rule helps to ensure the quality of dietary supplements so that consumers can be confident that the products they purchase contain what is on the label," said Commissioner of Food and Drugs Andrew C. von Eschenbach, M.D. "In addition, as a result of recent amendments to the Federal Food, Drug, and Cosmetic Act, by the end of the year, industry will be required to report all serious dietary supplement related adverse events to FDA."

Nitrospira-dominated biofilm within a thermal artesian spring: a case for nitrification-driven primary production in a geothermal setting.

Geobiology. 2012 Jun 21;

Authors: Marks CR, Stevenson BS, Rudd S, Lawson PA

Abstract
Water chemistry, energetic modeling, and molecular analyses were combined to investigate the microbial ecology of a biofilm growing in a thermal artesian spring within Hot Springs National Park, AR. This unique fresh water spring has a low dissolved chemical load and is isolated from both light and direct terrestrial carbon input – resulting in an oligotrophic ecosystem limited for fixed carbon and electron donors. Evaluation of energy yields of lithotrophic reactions putatively linked to autotrophy identified the aerobic oxidation of methane, hydrogen, sulfide, ammonia, and nitrite as the most exergonic. Small subunit (SSU) rRNA gene libraries from biofilm revealed a low-diversity microbial assemblage populated by bacteria and archaea at a gene copy ratio of 45:1. Members of the bacterial family ‘Nitrospiraceae’, known for their autotrophic nitrite oxidation, dominated the bacterial SSU rRNA gene library (approximately 45%). Members of the Thaumarchaeota ThAOA/HWCGIII (>96%) and Thaumarchaeota Group I.1b (2.5%), which both contain confirmed autotrophic ammonia oxidizers, dominated the archaeal SSU rRNA library. Archaea appear to dominate among the ammonia oxidizers, as only ammonia monooxygenase subunit A (amoA) genes belonging to members of the Thaumarchaeota were detected. The geochemical, phylogenetic, and genetic data support a model that describes a novel thermophilic biofilm built largely by an autotrophic nitrifying microbial assemblage. This is also the first observation of ‘Nitrospiraceae’ as the dominant organisms within a geothermal environment.

Previous animal studies have indicated that an extract from leaves of the Ginkgo biloba tree may protect against stroke-related brain injury. However, the mechanism involved has not been fully understood. In a recent NCCAM-funded study, researchers at Johns Hopkins University investigated whether and how the ginkgo extract Egb761 alters outcomes in mice with brain injury from stroke.

Soy protein supplements containing isoflavones do not significantly reduce the progression of atherosclerosis (build-up of plaque in the arteries) in postmenopausal women, according to a recent study published in the journal Stroke. However, a subgroup analysis of this study showed that soy supplements may benefit women who had experienced menopause within the last 5 years. Isoflavones are compounds similar to the female hormone estrogen and act like estrogen in some tissues. Previous epidemiological and laboratory research has suggested that isoflavones extracted from soybeans may have cardioprotective effects and may be a safe therapeutic alternative to hormone therapy for postmenopausal women.

According to the National Institute of Mental Health at NIH, Attention Deficit Hyperactivity Disorder (ADHD) affects 3 to 5 percent of children in the United States and it is one of the most common mental disorders that develop in children. NIMH states that children with ADHD have impaired functioning in multiple settings, including home, school, and in relationships with peers. Children with chronic conditions like ADHD are reported to have higher rates of complementary and alternative medicine use and may turn to dietary and herbal supplements such as St. John’s wort. However, according to authors of a new NCCAM-funded study, St. John’s wort does not appear to have an impact on the symptoms of ADHD in children and adolescents.
