The results presented here show that STC-1 cells, a model of intestinal endocrine cells, respond to a broad range of amino acids, including l-proline, l-serine, l-alanine, l-methionine, l-glycine, l-histidine, and alpha-methyl-amino-isobutyric acid (MeAIB) with a rapid increase in the intracellular Ca(2+) concentration ([Ca(2+)](i)). We sought to identify the mechanism by which amino acids indu...

The draft genome sequence of "Candidatus Liberibacter asiaticus" strain A4, isolated from a mandarin citrus in Guangdong, People's Republic of China, is reported. The A4 strain has a genome size of 1,208,625 bp, G+C content of 36.4%, 1,107 predicted open reading frames, and 53 RNA genes.

In addition to a previously published study about Central Asian Colletes bees we here further report on nine rarely collected and little known species. Now 85 species of Colletes are known from this region with three of them recorded for the first time: C. asiaticus Kuhlmann 1999, C. iranicus Noskiewicz 1962 and C. succinctus (Linnaeus 1758). Colletes pseudomirabilis sp. nov. is described from ...

Here, we report the draft genome sequence of "Candidatus Liberibacter asiaticus" strain FL17, isolated from a huanglongbing (HLB)-affected citrus tree in central Florida. The FL17 genome comprised 1,227,253 bp, with a G+C content of 36.5%, 1,175 predicted open reading frames, and 53 RNA genes.

The draft genome sequence of "Candidatus Liberibacter asiaticus" strain SGCA5 from an orange citrus tree in San Gabriel, California, is reported here. SGCA5 has a genome size of 1,201,445 bp, a G+C content of 36.4%, 1,152 predicted open reading frames (ORFs), and 42 RNA genes.

Bondarenko, Vladimir E., Glenna C. L. Bett, and Randall L. Rasmusson. A model of graded calcium release and L-type Ca channel inactivation in cardiac muscle. Am J Physiol Heart Circ Physiol 286: H1154–H1169, 2004;10.1152/ajpheart.00168.2003.—We have developed a model of Ca handling in ferret ventricular myocytes. This model includes a novel L-type Ca channel, detailed intracellular Ca movements...

The role of L-type calcium current ( I Ca,L) in impulse generation was studied in single sinoatrial nodal myocytes of the rabbit, with the use of the amphotericin-perforated patch-clamp technique. Nifedipine, at a concentration of 5 μM, was used to block I Ca,L. At this concentration, nifedipine selectively blocked I Ca,L for 81% without affecting the T-type calcium current ( I Ca,T), the fast ...

A perforated patch recording method was used to determine the effects of genistein (Gen), a protein tyrosine kinase (PTK) inhibitor, on basal L-type Ca2+ current ( I Ca,L) in feline atrial myocytes. Gen (50 μM) elicited biphasic changes in I Ca,L: an initial inhibition (-55 ± 4%; phase 1) followed by a secondary stimulation (34 ± 9%; phase 2) of I Ca,L. Withdrawal of Gen elicited a further pote...

Lysophosphatidylcholine (LPC), a metabolite of membrane phospholipids by phospholipase A(2), has been considered responsible for the development of abnormal vascular reactivity during atherosclerosis. Ca(2+) influx was shown to be augmented in atherosclerotic artery which might be responsible for abnormal vascular reactivity. However, the mechanism underlying Ca(2+) influx change in atheroscler...

The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is one of the most important pests of citrus (Citrus spp.) because of its status as a vector of Candidatus Liberibacter asiaticus (Las), the bacterium associated with citrus greening disease. The use of insecticides for vector control is the primary method of managing the spread of this pathogen. Imidacloprid is an inse...
