Hilbert’s Error? [PDF]

open access: yesThe Mathematical Intelligencer, 2018
It is well known that a center of a given circle cannot be constructed using only a straightedge and that this was proven by David Hilbert. Still it is not so clear what kind of object is proven to be non-existing. We analyze different attempts to define a geometric construction appearing in the literature and observe that none of them is really ...

Blood phenylalanine fluctuation in phenylketonuric children treated by BH4 or low-phenylalanine diet from birth

open access: yesScientific Reports, 2023
The prognosis of phenylketonuria (PKU) is related to the quality of metabolic control all life-long. PKU treatment is based on a low-Phe diet, 6R-tetrahydrobiopterin (BH4) treatment for the BH4-responsive PKU patients or enzyme replacement therapy ...

Micro-Checker: Software for identifying and correcting genotyping errors in microsatellite data

open access: yes, 2004
DNA degradation, low DNA concentrations and primer-site mutations may result in the incorrect assignment of microsatellite genotypes, potentially biasing population genetic analyses.

Determining factors of the cognitive outcome in early treated PKU: A study of 39 pediatric patients

open access: yesMolecular Genetics and Metabolism Reports, 2019
Phenylketonuria (PKU) is a disorder of phenylalanine metabolism, characterized by a neurotoxic phenylalanine (Phe) accumulation, and treatable with a life-long Phe-restricted diet. Though early and continuously treated PKU (ETPKU) patients exhibit normal

Improvement in the production of the human recombinant enzyme N-acetylgalactosamine-6-sulfatase (rhGALNS) in Escherichia coli using synthetic biology approaches

open access: yesScientific Reports, 2017
Previously, we demonstrated production of an active recombinant human N-acetylgalactosamine-6-sulfatase (rhGALNS) enzyme in Escherichia coli as a potential therapeutic alternative for mucopolysaccharidosis IVA.

Characterization of recombinant human lysosomal beta-hexosaminidases produced in the methylotrophic yeast Pichia pastoris

open access: yesUniversitas Scientiarum, 2016
β-hexosaminidases (Hex) are dimeric enzymes involved in the lysosomal degradation of glycolipids and glycans. They are formed by α- and/or β-subunits encoded byHEXA and HEXB genes, respectively.

Detecting crosstalk errors in quantum information processors [PDF]

open access: yesQuantum, 2019
Crosstalk occurs in most quantum computing systems with more than one qubit. It can cause a variety of correlated and nonlocal crosstalk errors that can be especially harmful to fault-tolerant quantum error correction, which generally relies on errors ...

Hyperphenylalaninemias genotyping: Results of over 60 years of history in Lombardy, Italy

open access: yesEndocrinology, Diabetes & Metabolism, 2023
Background Hyperphenylalaninemias (HPA) are due to several gene mutations, of which the PAH gene is the most frequently involved. Prevalence and incidence of disease vary between populations, with genotype/phenotype correlations not always capable to ...

“Double Hit” Homozygous Mutations for Two Different Rare Inborn Errors of Metabolism: A Burden for Countries with High Prevalences of Consangineous Marriages

open access: yesJournal of Pediatric Research, 2018
Inborn errors of metabolism comprise a broad range of genetic diseases of which most are inherited in an autosomal recessive manner. Although being rare, there is a significant increase in their rate especially in countries where consanguineous marriages

Dietary Treatment from Birth to Pregnancy in a Woman with Methylmalonic Aciduria

open access: yesMedicina, 2021
Methylmalonic aciduria is treated with a natural protein-restricted diet with adequate energy intake to sustain metabolic balance. Natural protein is a source of methylmalonic acid precursors, and intake is individually modified according to the severity
