 Choline containing phospholipids are essential for the integrity of the'cell'membrane. Minor changes in the lysophosphatidylcholine (lyso-PC)/phosphatidylcholine (PC) ratio may lead to neuronal damage and cell loss. Several studies have shown protein and lipid oxidation in Alzheimer’s disease (AD) affected brain regions. Amyloid-β peptides may induce(More)
OBJECTIVE To estimate whether weight loss or low gestational weight gain in class I-III obese women is associated with adverse maternal and neonatal outcomes compared with gestational weight gain within the new Institute of Medicine recommendations. METHODS This was a population-based cohort study, which included 32,991 obesity class I, 10,068 obesity(More)
All mutations known to cause familial Alzheimer's disease (AD) act by increasing the levels of soluble beta-amyloid peptide (A beta), especially the longer form, A beta42. However, in vivo elevation of soluble A beta in sporadic AD has so far not been shown. In the present study, we used enzyme-linked immunosorbent assays specific for A beta42 and A beta40(More)
The objective of this study was to compare cerebrospinal fluid (CSF) levels of the light subtype of the neurofilament proteins (NFL), tau, and beta-amyloid42 (Abeta42) in individuals with moderate or severe white matter changes (WMC) and in those with mild or no WMC. Twenty-two patients with Alzheimer's disease (AD), nine patients with subcortical vascular(More)
OBJECTIVE To estimate whether maternal obesity was associated with an increased risk for postpartum hemorrhage more than 1,000 mL and whether there was an association between maternal obesity and causes of postpartum hemorrhage and mode of delivery. METHODS A population-based cohort study including 1,114,071 women with singleton pregnancies who gave birth(More)
BACKGROUND The objective of this study was to assess, in a large data set from Swedish Medical Health Registries, whether maternal obesity and maternal morbid obesity were associated with an increased risk for various structural birth defects. METHODS The study population consisted of 1,049,582 infants born in Sweden from January 1, 1995, through December(More)
Estrogens may be implicated in the development of Alzheimer's disease (AD). Most of their effects are mediated via receptors whose function and expression may be modified by DNA polymorphisms. Here the estrogen receptor 1 gene (ESR1) polymorphisms XbaI and PvuII were analyzed in 214 AD patients and 290 controls. In logistic regression analysis, a(More)
Alternative cleavage of the amyloid precursor protein (APP) results in generation and secretion of both soluble APP (sAPP) and beta-amyloid (Abeta). Abeta is the main component of the amyloid depositions in the brains of Alzheimer's disease (AD) patients. Using Western blotting, we compared the levels of alpha-secretase cleaved sAPP, beta-secretase cleaved(More)
Cerebrospinal fluid (CSF) tau is a promising biochemical ante-mortem marker for Alzheimer's disease (AD). Levels are increased in AD compared to other dementias, neurological diseases and healthy controls. An age-related decrease in both soluble tau and tau bound to paired helical filaments has been shown in brains from non-demented subjects. To study tau(More)
Nitric oxide (NO) may play a role in the pathophysiology of Alzheimer's disease (AD). Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of NO synthase, is involved in regulation of NO production. Recently it has been reported that dimethylarginine dimethylaminohydrolase, an enzyme that hydrolyses ADMA into citrulline and dimethylamine, is(More)
