Semisynthetic sensor proteins enable metabolic assays at the point of care
Monitoring metabolites at the point of care could improve the diagnosis and management of numerous diseases. Yet for most metabolites, such assays are not available. We introduce semisynthetic, light-emitting sensor proteins for use in paper-based metabolic assays. The metabolite is oxidized by nicotinamide adenine dinucleotide phosphate, and the sensor changes color in the presence of the reduced cofactor, enabling metabolite quantification with the use of a digital camera. The approach makes any metabolite that can be oxidized by the cofactor a candidate for quantitative point-of-care assays, as shown for phenylalanine, ...

The modern term’s meaning has been expanded to include the ability to use language, numbers, images, computers, and other basic means to understand, communicate, gain useful knowledge, solve mathematical problems and use the dominant symbol systems of a culture.” The earliest written communication was in 3500-3000 BCE, with the earliest alphabet being from 1200-750 BCE.

The human gut microbiome -- which includes the community of trillions of bacteria living within our intestines -- has been called one of the next big frontiers in medicine.  In recent years, a growing body of research has shown that the bacteria in our gut exert a powerful influence on our immune and endocrine systems, brain health, mood and cognitive function, and other key biological processes. We know that the balance of good and bad bacteria in the gut can keep us healthy -- or can contribute to disease.

Scientists offer new insight on rare genetic condition
(University of Missouri-Columbia) All children are screened for a host of conditions at birth, such as Phenylketonuria, a genetic disorder that is passed by mutated genes from both parents to their offspring. Currently the primary way to manage the disease is through a restricted diet. Now, researchers at the University of Missouri, are using magnetic resonance imaging to learn more about the effects of this disorder on the brain and to assist scientists in developing therapeutic drugs.

Why Does Aspartame Have a Warning Label?
Discussion Phenylketonuria (PKU) is an autosomal recessive genetic disease. The PAH gene is found on chromosome 12 and has more than 600 mutations associated with it. The incidence varies but PKU is primarily found in Caucasian populations. The PAH gene codes for phenylalanine hydroxylase (PAH) which catalyzes the amino acid phenylalanine (Phe) to tyrosine. PAH uses a cofactor called tetrahydrobiopterin (BH4) in this process. With a deficiency in PAH, Phe accumulates and can cause severe cognitive impairment and global developmental delay, microcephaly, seizures, poor growth and poor skin pigmentation. Tyrosine also decrea...

Determination of Phenylalanine and Tyrosine by High Performance Liquid Chromatography-Tandem Mass Spectrometry
Hyperphenylalaninemia/phenylketonuria (PKU) is one of the most common inborn errors of amino acid metabolism affecting about 1:15,000 infants in the United States. PKU is an autosomal recessive disorder that if untreated results in mental retardation. The most common cause of PKU is deficiency of the enzyme phenylalanine hydroxylase that converts phenylalanine to tyrosine. Tyrosine deficiency results in impaired synthesis of catecholamines and thyroxine. Less commonly, it can result from defects in the synthesis or regeneration of tetrahydrobiopterin (BH4), an essential cofactor for the enzyme phenylalanine hydroxylase. In...

My last post was on the effects of exercise on the brain; here I explore nutrition: During the winter of 1944-1945, a terrible famine swept through the Netherlands and carried on until liberation in May 1945.
