Perinatal asphyxia (PA) is associated with long-term neuronal damage and cognitive deficits in adulthood, such as learning and memory disabilities. After PA, specific brain regions are compromised, including neocortex, hippocampus, basal ganglia, and ascending neuromodulatory pathways, such as dopamine system, explaining some of the cognitive disabilities. We hypothesize that other neuromodulat...

During protracted myocardial ischemia, ATP depletion promotes Na+ accumulation in sympathetic terminals and prevents vesicular storage of norepinephrine (NE). This forces the reversal of the neuronal uptake1 transporter, and NE is massively released (carrier-mediated release). We had shown that histamine H3 receptors (H3Rs) modulate ischemic NE release in animals. We have now used a human model...

Liver-expressed chemokine (LEC)/CCL16 is a human CC chemokine that is constitutively expressed by the liver parenchymal cells and present in the normal plasma at high concentrations. Previous studies have shown that CCL16 is a low-affinity ligand for CCR1, CCR2, CCR5, and CCR8 and attracts monocytes and T cells. Recently, a novel histamine receptor termed type 4 (H4) has been identified and sho...

Histamine H3 receptors modulate histamine synthesis, although little is known about the transduction mechanisms involved. To investigate this issue, we have used a preparation of rat brain cortical miniprisms in which histamine synthesis can be modulated by depolarization and by H3 receptor ligands. When the miniprisms were incubated in presence of forskolin, dibutyryl-cAMP, or 3-isobutyl-1-met...

Recent studies have shown that cimetidine, burimamide and improgan (also known as SKF92374, a cimetidine congener lacking H2 antagonist activity) induce antinociception after intracerebroventricular administration in rodents. Because these substances closely resemble the structure of histamine (a known mediator of some endogenous analgesic responses), yet no role for known histamine receptors h...

We investigated the role of histamine H1 receptors in mediating the anorectic effect of intraperitoneally injected amylin (5 and 20 microg/kg), the amylin agonist salmon calcitonin (sCT; 10 microg/kg), leptin (1.3 mg/kg), and cholecystokinin (CCK; 20 microg/kg). The experiments were performed with mice lacking functional H1 receptors (H1Rko) and wild-type (WT) controls. The mice were also injec...

The South African Traditional Health Practitioners Act 22 of 2007 is now fait accompli. The Act has been promulgated and the Department of Health (DoH) is proceeding with its implementation. An Interim Traditional Health Practitioners Council and a dedicated DoH deputy director have been appointed, the appointment of a registrar is being finalised, and the DoH has conducted a roadshow to introd...

The title compound, [RhCl(C(21)H(21)P)(2)(CO)]·C(3)H(6)O, was precipitated in trace yield from a reaction of RhCl(cod)(THP) with P(p-tol)(3) in a 1:1 acetone-d(6)/CD(3)OD solution under a hydrogen atmosphere [p-tol = p-tolyl, THP = tris-(hydroxy-meth-yl)phosphine, P(CH(2)OH)(3), and cod = 1,5-cyclo-octa-diene]. The complex displays a square-planar geometry around the Rh(I) atom. The complex mol...

We thank the Ministry of Social Welfare and Health, the National Research and Development Centre for Welfare and Health, Statistics Finland, and the Data Protection Authority for giving permission to link the registers. Contributors: MK designed and coordinated the study and wrote the paper, THP analysed the data and wrote the paper. JM did the data linkage and produced the data. JS interpreted...
