The Swedish and Finnish states are significant owners of enterprises. In both countries, the results for the state-owned enterprises (SOE) are compiled into an annual report presented to the Parliament. It is a way to report on financial performance as well as a way to build trust and legitimize state ownership. The document is thus a meeting point and place of negotiation foreconomic and politica
In this article, I consider the use of seemingly old nominative forms (ONF) in object position. The phenomenon is noted for the dialects of Västerbotten (in Northern Sweden) by several authors. Earlier works imply that the phenomenon is rather recent (early 1900s) and that the phenomenon is in more common usage in the inland rural areas than by the more urban coast. I discuss the structural analysIn this article, I consider the use of seemingly old nominative forms (ONF) in object position.

Subcellular membrane systems are highly enriched in dolichol, whose role in organelle homeostasis and endosomal-lysosomal pathway remains largely unclear besides being involved in protein glycosylation. DHDDS encodes for the catalytic subunit (DHDDS) of the enzyme cis-prenyltransferase (cis-PTase), involved in dolichol biosynthesis and dolichol-dependent protein glycosylation in the endoplasmic re
We describe a new Type II congenital disorder of glycosylation (CDG-II) caused by mutations in the conserved oligomeric Golgi (COG) complex gene, COG8. The patient has severe psychomotor retardation, seizures, failure to thrive and intolerance to wheat and dairy products. Analysis of serum transferrin and total serum N-glycans showed normal addition of one sialic acid, but severe deficiency in sub
Intracranial hemorrhage in a term neonate is a rare event in the absence of an identifiable precipitating factor such as severe thrombocytopenia, mechanical trauma, asphyxia, infections, or congenital vascular malformations. Congenital disorders of glycosylation are a genetically and clinically heterogeneous group of multisystem disorders characterized by the abnormal glycosylation of a number of
BACKGROUND: Kwashiorkor, a form of severe malnutrition with high mortality, is characterized by edema and systemic abnormalities. Although extremely common, its pathophysiology remains poorly understood, and its characteristic physical signs are unexplained.OBJECTIVE: Because kwashiorkor can develop in protein-losing enteropathy, which is caused by a loss of enterocyte heparan sulfate proteoglycan
We present two sibs with congenital disorder of glycosylation (CDG) type Id. Each shows severe global delay, failure to thrive, seizures, microcephaly, axial hypotonia, and disaccharidase deficiency. One sib has more severe digestive issues, while the other is more neurologically impaired. Each is compound heterozygous for a novel point mutation and an already known mutation in the ALG3 gene that
We describe a case of congenital disorder of glycosylation with chronic diarrhea, progressive liver cirrhosis, and recurrent infections. Transferrin analysis showed only hyposialylation, but analysis of total serum N-glycans indicated loss of additional sugars, arguing that the latter generates a more informative picture to search for the primary defect.
We present the clinical, molecular, and biochemical diagnosis of a patient with congenital disorder of glycosylation (CDG)-Ih. We report significant brain dysfunction in this multisystem disease, further expanding its complex clinical spectrum.
MPI encodes phosphomannose isomerase, which interconverts fructose 6-phosphate and mannose 6-phosphate (Man-6-P), used for glycoconjugate biosynthesis. MPI mutations in humans impair protein glycosylation causing congenital disorder of glycosylation Ib (CDG-Ib), but oral mannose supplements normalize glycosylation. To establish a mannose-responsive mouse model for CDG-Ib, we ablated Mpi and provid
We describe a new cause of congenital disorder of glycosylation-Ic (CDG-Ic) in a young girl with a rather mild CDG phenotype. Her cells accumulated lipid-linked oligosaccharides lacking three glucose residues, and sequencing of the ALG6 gene showed what initially appeared to be a homozygous novel point mutation (338G>A). However, haplotype analysis showed that the patient does not carry any patern
Patients with Type I congenital disorders of glycosylation (CDG-I) make incomplete lipid-linked oligosaccharides (LLO). These glycans are poorly transferred to proteins resulting in unoccupied glycosylation sequons. Mutations in phosphomannomutase (PMM2) cause CDG-Ia by reducing the activity of PMM, which converts mannose (Man)-6-P to Man-1-P before formation of GDP-Man. These patients have reduce
Congenital disorder of glycosylation (CDG) type Ic, the second largest subtype of CDG, is caused by mutations in human ALG6 (hALG6). This gene encodes the alpha1,3-glucosyltransferase that catalyzes transfer of the first glucose residue to the lipid-linked oligosaccharide precursor for N-linked glycosylation. In this report, we describe the first adult patient diagnosed with CDG-Ic, carrying two p
CONTEXT: Inborn errors in protein glycosylation, such as the congenital disorders of glycosylation (CDGs), generate multifaceted syndromes that impair many organ systems. We here report the diagnosis of the third known patient with CDG-Id.RESULTS: The patient's phenotype was extremely severe, and she succumbed at 19 d of age. Leading features included hyperinsulinemic hypoglycemia, and autopsy rev
In this report we describe the first two US patients with congenital disorder of glycosylation type Ig (CDG-Ig). Both patients presented with symptoms indicating CDG, including developmental delay, hypotonia and failure to thrive, and tested positive for deficient glycosylation of transferrin. Labeling of the patients' lipid-linked oligosaccharides suggested mutations in the hALG12 gene, encoding
