EURO-NMD registry: federated FAIR infrastructure, innovative technologies and concepts of a patient-centred registry for rare neuromuscular disorders.

Background: The EURO-NMD Registry collects data from all neuromuscular patients seen at EURO-NMD's expert centres. In-kind contributions from three patient organisations have ensured that the registry is patient-centred, meaningful, and impactful. The consenting process covers other uses, such as research, cohort finding and trial readiness.

Roles of pro-angiogenic and anti-angiogenic factors as well as matrix metalloproteinases in healing of NSAID-induced small intestinal ulcers in rats.

Aims: We examined changes in the expression of a pro-angiogenic factor, vascular endothelial growth factor (VEGF), and an anti-angiogenic factor, endostatin, as well as matrix metalloproteinase (MMP)-2 and MMP-9 in the rat small intestine after administration of indomethacin and investigated the roles of these factors in the healing of indomethacin-induced small intestinal ulcers.

Main Methods: Male SD rats were given indomethacin (10mg/kg) p.o.

Aggravation by paroxetine, a selective serotonin reuptake inhibitor, of antral lesions generated by nonsteroidal anti-inflammatory drugs in rats.

Recent clinical studies have suggested a risk of adverse gastric reactions from the concomitant use of selective serotonin (5-HT) reuptake inhibitors (SSRIs) with nonsteroidal anti-inflammatory drugs (NSAIDs). We examined the adverse effects of SSRIs on antral lesions produced by indomethacin in rats. Rats fasted for 24 h were refed for 1 h, then administered indomethacin (30 mg/kg s.

Transgenerational hormonal imprinting caused by vitamin A and vitamin D treatment of newborn rats. Alterations in the biogenic amine contents of the adult brain.

Biogenic amines (norepinephrine, dopamine, homovanillic acid, serotonin and 5-hyroxyindole acetic acid) were measured by HPLC method in adult F1 generation rats' brain regions (brainstem, hypothalamus, hippocampus, striatum and frontal cortex), whose mothers (P generation) were treated with vitamin A or vitamin D neonatally (hormonal imprinting). Many significant differences were found, related to the maternally untreated controls. In the earlier studied P generation females, vitamin A consistently influenced the serotonerg system (5HIAA), while vitamin D the dopaminerg system (DA or HVA).

Effect of neonatal nociceptin or nocistatin imprinting on the brain concentration of biogenic amines and their metabolites.

Noradrenaline (NA), dopamine (DA), homovanillic acid (HA), serotonin (5HT) and 5-hydroxyindole acetic acid (5HIAA) content of five brain regions (hypothalamus, hippocampus, brainstem, striatum and frontal cortex) and the cerebrospinal fluid (CSF) was measured in adult (three months old) male and female rats treated neonatally with a single dose of 10 microg nociceptin (NC) or 10 microg nocistatin (NS) for hormonal imprinting. The biogenic amine and metabolite content of cerebrospinal fluid was also determined. In NC treated animals the serotonergic, dopaminergic as well as noradrenergic systems were influenced by the imprinting.

Measurement of K-27, an oxime-type cholinesterase reactivator by high-performance liquid chromatography with electrochemical detection from different biological samples.

K-27 is a bisquaternary asymmetric pyridinium aldoxime-type cholinesterase reactivator of use in the treatment of poisoning with organophosphorous esterase inhibitors. A sensitive, simple and reliable reverse-phase high-performance liquid chromatographic method with electrochemical detection was developed for the measurement of K-27 concentrations in rat brain, cerebrospinal fluid, serum and urine samples. Male Wistar rats were treated intramuscularly with K-27 and the samples were collected 60 min later.

Perinatal alcohol exposure enhances nocistatin levels in adulthood.

In earlier experiments perinatal hormonal imprinting by alcohol decreased the hormone content of immune cells for life. In the present study, both a single day (15% on the third postnatal day) and a long-term treatment schedule of alcohol exposure (3% for 21 days) of dams during lactation significantly (P < 0.01) enhanced endogenous levels of nocistatin in the blood plasma as well as in the cerebrospinal fluid of the offspring, measured in 3-month-old rats.

[Effect of nociceptin on histamine and serotonin release in the central nervous system].

Role in pain sensation of both nociceptin (NC), the bioactive heptadecapeptide sequence of preproorphaninFQ and of histamine has been widely evidenced in the central nervous system (CNS). In the current series of experiments effect of intracerebroventricularly (i.c.

[Endogenous nociceptin level in ischemic stroke: connection to serotonin system].

Particular role of the heptadecapeptide nociceptin (orphanin FQ), the endogenous agonist of the NOP receptor, has been widely demonstrated in the regulation of pain sensation and anxiety-related behavior. In our best knowledge this is the first study reporting plasma nociceptin levels in 26 acute stroke and 6 transiens ischemic attack (TIA) patients. We have found significantly elevated plasma nociceptin levels in all the three groups of patients studied (stroke influencing the carotis or the lacunar region and TIA).
