In higher plants formate dehydrogenase (FDH, EC 1.2.1.2.) is a mitochondrial, NAD-dependent enzyme. We previously reported that in potato (Solanum tuberosum L.) FDH expression is high in tubers but low in green leaves. Here we show that in isolated tuber mitochondria FDH is involved in formate-dependent O2 uptake coupled to ATP synthesis. The effects of various environmental and chemical factor...

The prevalence of familial dysalbuminemic hyperthyroxinemia (FDH), a condition sometimes mistaken for hyperthyroidism, has not been clearly established. I present a study of the prevalence of FDH in serum samples received for thyroid-function tests in a reference laboratory. A prospective study of 15,674 serum samples was carried out over 24 months, of which 13,232 cases were from women (84.42%...

BACKGROUND Enzymatic NADH or NADPH-dependent reduction is a widely applied approach for the synthesis of optically active organic compounds. The overall biocatalytic conversion usually involves in situ regeneration of the expensive NAD(P)H. Oxidation of formate to carbon dioxide, catalyzed by formate dehydrogenase (EC 1.2.1.2; FDH), presents an almost ideal process solution for coenzyme regener...

Alcoholism has been associated with folate deficiency in humans and laboratory animals. Previous study showed that ethanol feeding reduces the dehydrogenase and hydrolase activity of 10-formyltetrahydrofolate dehydrogenase (FDH) in rat liver. Hepatic ethanol metabolism generates acetaldehyde and acetate. The mechanisms by which ethanol and its metabolites produce toxicity within the liver cells...

Familial dysalbuminemic hyperthyroxinemia (FDH-T4) and hypertriiodothyroninemia (FDH-T3) are dominantly inherited syndromes characterized by a high concentration of thyroid hormone in the blood stream. The syndromes do not cause disease, because the concentration of free hormone is normal, but affected individuals are at risk of erroneous treatment. FDH-T4 is the most common cause of euthyroid ...

The provision of local public services has become one the main concerns governments. Therefore, selection most appropriate form management to maximize efficiency levels in been widely analyzed throughout academic literature. In this context, aim paper is add new knowledge literature on services. To end, we propose study four forms (interested indirect management; by concession; intermunicipal c...

The purpose of this article is to propose a reinterpretation of the traditional flypaper effect according to which central government transfers to local governments increase public spending by more than do increases in private income. Here, higher transfers from the federal government might induce less efficiency in local tax collection opposed to the income effect. Initially, we build a model ...

BACKGROUND Focal Dermal Hypoplasia (FDH) is a genetic disorder characterized by developmental defects in skin, skeleton and ectodermal appendages. FDH is caused by dominant loss-of-function mutations in X-linked PORCN. PORCN orthologues in Drosophila and mice encode endoplasmic reticulum proteins required for secretion and function of Wnt proteins. Wnt proteins play important roles in embryo de...

Fourier-domain holography (FDH) is investigated as a candidate for holographic optical coherence imaging to produce real-time images of structure inside living tissue and turbid media. The effects of spatial filtering, the background intensity distributions, and the role of background noise in determining dynamic range are evaluated for both FDH and image-domain holography (IDH). The grating wa...
