13. Induced chromosome rearrangements and morphologic variation in Candida albicans.
We have isolated a mutant of Candida albicans that switches between colony morphologies at high frequencies in a strain with several genetic markers. This strain, 1183, has an altered karyotype with two extra chromosomes. The 1183 karyotype is unstable upon passage. Using DNA transformation with the URA3 gene flanked by sequences from the C. albicans repeat

14. Mechanical Regulation of the Proangiogenic Factor CCN1/CYR61 Gene Requires the Combined Activities of MRTF-A and CREB-binding Protein Histone Acetyltransferase*
Smooth muscle-rich tissues respond to mechanical overload by an adaptive hypertrophic growth combined with activation of angiogenesis, which potentiates their mechanical overload-bearing capabilities. Neovascularization is associated with mechanical strain-dependent induction of angiogenic factors such as CCN1, an immediate-early gene-encoded matricellular m

15. Connection between Elastin Haploinsufficiency and Increased Cell Proliferation in Patients with Supravalvular Aortic Stenosis and Williams-Beuren Syndrome
To elucidate the pathomechanism leading to obstructive vascular disease in patients with elastin deficiency, we compared both elastogenesis and proliferation rate of cultured aortic smooth-muscle cells (SMCs) and skin fibroblasts from five healthy control subjects, four patients with isolated supravalvular aortic stenosis (SVAS), and five patients with Willi

16. Activated macrophages depress the contractility of rabbit carotids via an L-arginine/nitric oxide-dependent effector mechanism. Connection with amplified cytokine release.
Inflammatory mediators released by macrophages (M phi) are believed to be involved in septic vasoplegia. To investigate the effect of M phi on vascular reactivity, excised rabbit carotids were exposed intraluminally either to peritoneal rabbit M phi, activated by 18 h of incubation with 1 microgram/ml lipopolysaccharide, or to the supernatants (SPN) derived

17. Inhibitory control of local excitatory circuits in the guinea-pig hippocampus.
1. Exposure to the gamma-aminobutyric acid antagonist, picrotoxin, causes the discharge of hippocampal pyramidal cells to become synchronized. Synaptic mechanisms underlying the development of synchrony were investigated by recording from pairs of cells in the CA3 region of guinea-pig hippocampal slices. 2. Picrotoxin suppressed unitary inhibitory synaptic e
