Regulation of photosynthetic sucrose synthesis: a role for calcium?.

Planta

Brauer M, Sanders D, Stitt M.
PMID: 24197102
Planta. 1990 Sep;182(2):236-43. doi: 10.1007/BF00197117.

We have investigated whether changes of the cytosolic free-calcium concentration could regulate photosynthetic sucrose synthesis. Partially purified enzymes from spinach (Spinacea oleracea L.) leaves were assayed using calcium-EGTA buffers to obtain defined free-calcium concentrations in the low micromolar and...

Phenotypic variation in exopolysaccharide production in the marine, aerobic nitrogen-fixing unicellular cyanobacterium Cyanothece sp.

World journal of microbiology & biotechnology

Reddy KJ, Soper BW, Tang J, Bradley RL.
PMID: 24415305
World J Microbiol Biotechnol. 1996 Jul;12(4):311-8. doi: 10.1007/BF00340206.

The aerobic nitrogen-fixing cyanobacterium, Cyanothece sp. BH68K produces non-mucoid variants defective in exopolysaccharide (EPS) production at a high frequency. The EPS-producing wild-type colonies (EPS(+)) have a characteristic smooth and shiny appearance which allows them to be easily distinguished from...

Putative Single Quantum and Single Fibre Excitatory Postsynaptic Currents Show Similar Amplitude Range and Variability in Rat Hippocampal Slices.

The European journal of neuroscience

Raastad M, Storm JF, Andersen P.
PMID: 12106447
Eur J Neurosci. 1992 Oct;4(1):113-117. doi: 10.1111/j.1460-9568.1992.tb00114.x.

Transmission at excitatory synapses in the mammalian brain is thought to depend on the release of transmitter quanta through exocytosis of presynaptic vesicles (Katz, 1969). The number of vesicles released by a single presynaptic action potential is important for...

Second messenger-controlled membrane conductance in locust (Locusta migratoria) olfactory neurons.

Journal of insect physiology

Breer H, Hanke W, Wegener JW.
PMID: 12770422
J Insect Physiol. 1997 Jun;43(6):595-603. doi: 10.1016/s0022-1910(97)00008-5.

The membrane conductance of olfactory neurons of Locusta migratoria was examined using the whole-cell configuration of the patch-clamp technique. Intracellular application of the second messenger inositol 1,4,5 trisphosphate (IP(3)) via a dual pipette technique elicited a clear increase in...

Adherence of Bilophila wadsworthia to cultured human embryonic intestinal cells.

Anaerobe

Gerardo SH, Garcia MM, Wexler HM, Finegold SM.
PMID: 16887620
Anaerobe. 1998 Feb;4(1):19-27. doi: 10.1006/anae.1997.0134.

Adherence of Bilophila wadsworthia to the cultured human embryonic intestinal cell line, Intestine 407 (Int 407), varied among the strains tested from strongly adherent (76-100% cells positive for one or more adherent bacteria) to non- or weakly adherent (0-25%...

Bacteroides fragilis adherence to Caco-2 cells.

Anaerobe

Ferreira EO, Falcão LS, Vallim DC, Santos FJ, Andrade JR, Andrade AF, Vommaro RC, Ferreira MC, Domingues RM.
PMID: 16887674
Anaerobe. 2002 Dec;8(6):307-14. doi: 10.1016/S1075-9964(03)00008-8.

The ability of ten Bacteroides fragilis strains isolated from intestinal and non-intestinal infections, normal flora and environment to adhere to human colon carcinoma cells, Caco-2, was examined. The adherence capacity varied among the strains tested from strongly adherent (76-100%)...

Septate junctions in the gastrodermal epithelium of Phialidium: A fine structural study utilizing ruthenium red.

Tissue & cell

Leik J, Kelly DE.
PMID: 18631524
Tissue Cell. 1970;2(3):435-41. doi: 10.1016/s0040-8166(70)80043-x.

The septate junctions of the gastrodermis of the hydromedusa, Phialidium gregarium, are composed of septa (80 A thick) which bridge the gap (130 A) between the outer leaflets of the plasma membranes of adjacent cells. The septa are parallel...

Calcium is Necessary for Motility in the Diatom Amphora coffeaeformis.

Plant physiology

Cooksey B, Cooksey KE.
PMID: 16661126
Plant Physiol. 1980 Jan;65(1):129-31. doi: 10.1104/pp.65.1.129.

The marine diatom Amphora coffeaeformis required Ca(2+) and bicarbonate for motility. Movement was inhibited by the Ca(2+)-blocking agents ruthenium red and alpha-isopropyl-alpha-[(N-methyl-N-homoveratryl)-alpha- aminopropyl]-3,4,5-trimethoxy phenyl acetonitrile and the metabolic energy uncoupler, carbonyl cyanide 3-chlorophenylhydrazone. 3-(3',4-Dichlorophenyl)-1,1-Dimethyl urea was without effect on...

Altered distribution of some surface glycosaminoglycans and glycoconjugates on human blood platelets in diabetes mellitus.

Platelets

Lupu C, Rizescu M, Calb M.
PMID: 21043720
Platelets. 1994;5(4):201-8. doi: 10.3109/09537109409006047.

The distribution of some proteoglycan anionic sites and carbohydrate moieties on the diabetic platelet surface has been investigated by cytochemical methods. Human blood platelets obtained from either diabetic patients (serum glycaemia 9.6-19.2 mmol/L) or normal donors were labeled with...

Illustration of extensive extracellular matrix at the epithelial-mesenchymal interface within the renal stem/progenitor cell niche.

BMC clinical pathology

Minuth WW, Denk L.
PMID: 23009620
BMC Clin Pathol. 2012 Sep 25;12:16. doi: 10.1186/1472-6890-12-16.

BACKGROUND: Stem/progenitor cells are promising candidates to treat diseased renal parenchyma. However, implanted stem/progenitor cells are exposed to a harmful atmosphere of degenerating parenchyma. To minimize hampering effects after an implantation investigations are in progress to administer these cells...

The effects of ruthenium red, lanthanum, fluorescein isothiocyanate and trifluoperazine on vesicle transport, vesicle fusion and tip extension in pollen tubes.

Planta

Picton JM, Steer MW.
PMID: 24249263
Planta. 1985 Jan;163(1):20-6. doi: 10.1007/BF00395892.

The effects of ruthenium red, lanthanum, fluorescein isothiocyanate and trifluoperazine, all antagonists of Ca(2+) function in cells, have been studied in growing pollen tubes of Tradescantia virginiana. All four drugs inhibit pollen-tube growth but bring about different ultrastructural changes...
