Facial recognition is central to the diagnosis of many syndromes, and craniofacial patterns may reflect common etiologies. In the pleiotropic Bardet-Biedl syndrome (BBS), a primary ciliopathy with intraflagellar transport dysfunction, patients have a characteristic facial "gestalt" that dysmorphologists have found difficult to characterize. Here, we use(More)
This work aimed to evaluate the potential role of the 5-HT(7) receptor in nociception secondary to a sensitizing stimulus in mice. For this purpose, the effects of relevant ligands (5-HT(7) receptor agonists: AS-19, MSD-5a, E-55888; 5-HT(7) receptor antagonists: SB-258719, SB-269970; 5-HT(1A) receptor agonist: F-13640; 5-HT(1A) receptor antagonist:(More)
We validated the pig eye as a model of glaucoma, based on chronic elevation of intraocular pressure (IOP). IOP was elevated by cauterising three episcleral veins in each of the left eyes of five adult pigs. Right eyes were used as controls. Measurement of IOP was performed during the experiment with an applanation tonometer (Tono-Pen). Five months after(More)
PURPOSE To characterize and compare the expression of neurotrophins (NTs) and their receptors within adult porcine retinal ganglion cells (RGCs) in vivo and in vitro. METHODS The distribution of nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3) and -4 (NT-4), and their high-affinity receptors TrkA, TrkB, TrkC and(More)
Recurrent microdeletions of 8p23.1 that include GATA4 and SOX7 confer a high risk of both congenital diaphragmatic hernia (CDH) and cardiac defects. Although GATA4-deficient mice have both CDH and cardiac defects, no humans with cardiac defects attributed to GATA4 mutations have been reported to have CDH. We were also unable to identify deleterious GATA4(More)
The release of [3H]GABA from slices of rat substantia nigra pars reticulata induced by increasing extracellular K+ from 6 to 15 mM in the presence of 10 microM sulpiride was inhibited by 73 +/- 3% by 1 microM SCH 23390, consistent with a large component of release dependent upon D1 receptor activation. The histamine H3 receptor-selective agonist immepip (1(More)
The aim of this study was to identify by immunocytochemistry the distribution of nitric oxide synthase (NOS) in human and murine gastric epithelium. Using two different antisera specific for neuronal NOS (nNOS), we detected nNOS immunoreactivity in endocrine cells of the epithelium of the body and pyloric regions as well as in ganglion cells of the(More)
Programmed cell death occurs naturally, as a physiological process, during the embryonic development of multicellular organisms. In the retina, which belongs to the central nervous system, at least two phases of cell death have been reported to occur during development. An early phase takes place concomitant with the processes of neurogenesis, cell(More)
1. A study was made of the regulation of [(3)H]-gamma-aminobutyric acid ([(3)H]-GABA) release from slices of rat striatum by endogenous dopamine and exogenous histamine and a histamine H(3)-agonist. Depolarization-induced release of [(3)H]-GABA was Ca(2+)-dependent and was increased in the presence of the dopamine D(2) receptor family antagonist, sulpiride(More)
PURPOSE Neurofilaments (NF) are neuronal cytoskeletal components and immunostaining against them has been used to visualize retinal ganglion cells (RGC) and their axons. Since the RGC cytoskeleton exhibits differential damage in diseases such as glaucoma, we examined the distribution of light, medium, and heavy NF subunits (NF-L, NF-M, and NF-H(More)
