The dynamics of retinal embryogenesis have been well characterized previously in terms of cell proliferation, genesis and migration, whereas overall cell type differentiation within the retinal layers has been less thoroughly explored. In the present study, phenotypical differentiation of all 7 major retinal cell types was examined in the developing porcine retina using one cell-specific immunohis
INTRODUCTION: Increasing evidence suggests that optimal food choice is critical for sizable prevention of western diseases such as cardiovascular disease and cancer. The Mediterranean diet is an important step in this direction. Moreover, substantially lower rates of Western disease, even compared to Mediterranean countries, have been observed among hunter-gatherers and other non-western populatio
Languages vary typologically in their lexicalization of Path of motion (Talmy 1991). Furthermore, lexicalization patterns are argued to affect syntactic packaging at the level of the clause (e.g. Slobin 1996b) and tend to transfer from a first (L1) to a second language (L2) in second language acquisition (e.g. Cadierno 2004). From this crosslinguistic and developmental evidence, typological prefer
The PR interval on the electrocardiogram reflects atrial and atrioventricular nodal conduction time. The PR interval is heritable, provides important information about arrhythmia risk, and has been suggested to differ among human races. Genome-wide association (GWA) studies have identified common genetic determinants of the PR interval in individuals of European and Asian ancestry, but there is a
Laser Doppler perfusion imaging offers a new modality for in vivo monitoring of the superficial blood perfusion in biological tissue, In this study, the superficial blood perfusion of malignant nonmelanoma skin tumours and the surrounding normal skin was measured in conjunction with photodynamic therapy (PDT) using topical delta-aminolaevulinic acid (ALA)-induced protoporphyrin IX as a photosensit
Recently, hippocampal neuropeptide Y (NPY) gene therapy has been shown to effectively suppress both acute and chronic seizures in animal model of epilepsy, thus representing a promising novel antiepileptic treatment strategy, particularly for patients with intractable mesial temporal lobe epilepsy (TLE). However, our previous studies show that recombinant adeno-associated viral (rAAV)-NPY treatmen
Population-based registries may provide data complementary to that from basic science and clinical intervention studies, all of which essential for establishing recommendations for the management of patients in the real world. The same quality criteria apply for the evidence-based label, and both high representation and good data quality are crucial in registry studies. Registries with high covera
ABSTRACT: INTRODUCTION: The amplification event occurring at chromosome locus 11q13, reported in several different cancers, includes a number of potential oncogenes. We have previously reported amplification of one such oncogene, namely CCND1, to be correlated with an adverse effect of tamoxifen in premenopausal breast cancer patients. Over-expression of cyclin D1 protein, however, confers tamoxif
The phosphatidylinositol 3-kinases-AKT-mammalian target of rapamycin pathway (PI3K/AKT/mTOR) is central in colorectal tumors. Data on its role in hereditary cancers are, however, scarce and we therefore characterized mutations in PIK3CA and KRAS, and expression of PIK3CA, phosphorylated AKT, and PTEN in colorectal cancers linked to hereditary nonpolyposis colorectal cancer (HNPCC). Sequencing was
We investigated implications of nitric oxide (NO) derived from islet neuronal constitutive NO synthase (ncNOS) and inducible NOS (iNOS) on insulin secretory mechanisms in the mildly diabetic GK rat. Islets from GK rats and Wistar controls were analysed for ncNOS and iNOS by HPLC, immunoblotting and immunocytochemistry in relation to insulin secretion stimulated by glucose or l-arginine in vitro an
BACKGROUND: Trauma induces transcapillary leakage of fluid and proteins because of increased microvascular permeability. Based on studies showing that prostacyclin (PGI2) has permeability-reducing properties, in the present study, we investigated whether PGI2 reduces plasma volume (PV) loss after a nonhemorrhagic trauma. METHODS: The study was performed on anesthetized Sprague-Dawley rats exposed
Abstract Previously, glucose concentration has been presumed to be similar in seroma, lymph, and plasma. However, there are few studies actually measuring glucose concentration in seroma. The aim of this pilot study was to determine if the glucose concentration in seroma is similar to that in plasma, as it has previously been presumed. Biochemical analysis of seroma was performed on 11 patients th
ABSTRACT: Rheumatoid arthritis (RA) is a chronic inflammatory disease with a heritability of 60%. Genetic contributions to RA are made by multiple genes, but only a few gene associations have yet been confirmed. By studying animal models, reduced capacity of the NADPH-oxidase (NOX) complex, caused by a single nucleotide polymorphism (SNP) in one of its components (the NCF1 gene), has been found to
The marketplace for probiotic foods is burgeoning, measured in billions of euro per annum. It is imperative, however, that all bacterial strains are fully assessed for human safety. The ability to bind fibrinogen is considered a potential pathogenicity trait that can lead to platelet aggregation, serious medical complications, and in some instances, death. Here we examined strains from species fre
The aim of this work was to study the diffusion-related signal attenuation curves (signal-vs.-b curves) measured perpendicular and parallel to the neuronal fibers of the corticospinal tract in vivo and to determine whether effects of restricted diffusion could be observed when varying the diffusion time (T(D)). A biexponential model and a two-compartment model including exchange according to the K
The arthritis-susceptible DA rat is one of the most commonly used rat strains for genetic linkage analysis and is instrumental for the identification of many genetic loci. Even though DA rats were kept as inbred lines at different institutes and suppliers, it became obvious that the various breeding stocks differed genetically. To be able to compare the results from different linkage studies it is
The ability to subfractionate minor cellular subsets by multiparameter flow cytometry and to evaluate such cells for functional properties has been used to ascertain lineal relationships and detail developmental hierarchies in the hematopoietic system for more than 20 years. However, steady advances in technology combined with the use of novel cell surface markers continues to redefine the develop
Purpose In numerous studies vigabatrin medication has been associated with visual field constriction and alterations in the full-field electroretinogram (ff-ERG), but it is not clear whether these changes are reversible or not. The purpose of this study was to examine patients with visual field loss and reduced ff-ERG several years after discontinuing vigabatrin therapy, in order to investigate re
