UDP-glucose: Glucan Synthetase in Developing Cotton Fibers: I. Kinetic and Physiological Properties.

Plant physiology

Delmer DP, Heiniger U, Kulow C.
PMID: 16659924
Plant Physiol. 1977 Apr;59(4):713-8. doi: 10.1104/pp.59.4.713.

A uridine diphosphate(UDP)-glucose:glucan synthetase can be demonstrated in detached cotton fibers (Gossypium hirsutum L.) and in an isolated particulate fraction from such fibers. When assayed with detached fibers, the kinetics of the glucan synthetase activity with respect to variation...

Metabolism of cytidine and uridine in bean leaves.

Plant physiology

Ross C, Cole CV.
PMID: 16656905
Plant Physiol. 1968 Aug;43(8):1227-31. doi: 10.1104/pp.43.8.1227.

The metabolism of cytidine-2-(14)C and uridine-2-(14)C was studied in discs cut from leaflets of bean plants (Phaseolus vulgaris L.). Cytidine was degraded to carbon dioxide and incorporated into RNA at about the same rates as was uridine. Both nucleosides...

Signaling of the Purinergic System in the Joint.

Frontiers in pharmacology

Corciulo C, Cronstein BN.
PMID: 32038258
Front Pharmacol. 2020 Jan 24;10:1591. doi: 10.3389/fphar.2019.01591. eCollection 2019.

The joint is a complex anatomical structure consisting of different tissues, each with a particular feature, playing together to give mobility and stability at the body. All the joints have a similar composition including cartilage for reducing the friction...

Hexose-, inositol-, and nucleoside phosphate esters in germinating seeds of crested wheatgrass.

Plant physiology

Wilson AM, Harris GA.
PMID: 16656416
Plant Physiol. 1966 Nov;41(9):1416-9. doi: 10.1104/pp.41.9.1416.

Net synthesis of phosphate esters was measured in crested wheatgrass seeds [Agropyron desertorum (Fisch.) Schult.] to learn what phosphorylating reactions occur in early stages of germination. Phosphate esters were separated on ion exchange columns and identified by cochromatography and...

Pyrimidine metabolism in cotyledons of germinating alaska peas.

Plant physiology

Ross C, Coddington RL, Murray MG, Bledsoe CS.
PMID: 16657582
Plant Physiol. 1971 Jan;47(1):71-5. doi: 10.1104/pp.47.1.71.

Cotyledons from Pisum sativum L. cv. Alaska seeds were excised 12, 36, 108, 132, and 156 hours after imbibition in aerated distilled water. They were then incubated under aseptic conditions for 6 hours in solutions containing either uridine-2-(14)C or...

Calcium-dependent release of adenosine and uridine nucleotides from A549 cells.

Purinergic signalling

Tatur S, Kreda S, Lazarowski E, Grygorczyk R.
PMID: 18368524
Purinergic Signal. 2008 Jun;4(2):139-46. doi: 10.1007/s11302-007-9059-x. Epub 2007 Jul 25.

Extracellular nucleotides play an important role in lung defense, but the release mechanism and relative abundance of different nucleotide species secreted by lung epithelia are not well defined. In this study, to minimize cell surface hydrolysis, we used a...

Effects of alkaline phosphatase activity on nucleotide measurements in aquatic microbial communities.

Applied and environmental microbiology

Karl DM, Craven DB.
PMID: 16345634
Appl Environ Microbiol. 1980 Sep;40(3):549-61. doi: 10.1128/aem.40.3.549-561.1980.

Alkaline phosphatase (APase) activity was detected in aquatic microbial assemblages from the subtropics to Antarctica. The occurrence of APase in environmental nucleotide extracts was shown to significantly affect the measured concentrations of cellular nucleotides (adenosine triphosphate, adenosine diphosphate, adenosine...

Purine receptors and Ca(2+) signalling in the human blood-brain barrier endothelial cell line hCMEC/D3.

Purinergic signalling

Bintig W, Begandt D, Schlingmann B, Gerhard L, Pangalos M, Dreyer L, Hohnjec N, Couraud PO, Romero IA, Weksler BB, Ngezahayo A.
PMID: 21956217
Purinergic Signal. 2012 Mar;8(1):71-80. doi: 10.1007/s11302-011-9262-7. Epub 2011 Sep 29.

The expression and physiology of purine receptors of the human blood-brain barrier endothelial cells were characterised by application of molecular biological, gene-silencing and Ca(2+)-imaging techniques to hCMEC/D3 cells. Reverse transcription polymerase chain reaction showed the expression of the G-protein-coupled...

Inhibition of Methamphetamine-Induced Cytotoxicity in the U87-Cell Line by Atorvastatin-Conjugated Carbon Nanotubes.

Applied biochemistry and biotechnology

Nikeafshar S, Khazaei A, Tahvilian R.
PMID: 34611858
Appl Biochem Biotechnol. 2021 Oct 06; doi: 10.1007/s12010-021-03667-w. Epub 2021 Oct 06.

In biological systems, carbon nanotubes can enhance the biological effects of drugs and reduce their side effects. Methamphetamine (METH) is a stimulant drug that induces cell death in various cell types, primarily neural cells. On the other hand, specific...

Neuronal apoptosis in herpes simplex virus - 1 encephalitis (HSE).

Indian journal of medical microbiology

Athmanathan S, Vydehi BV, Sundaram C, Vemuganti GK, Murthy JM.
PMID: 17664814
Indian J Med Microbiol. 2001 Jul-Sep;19(3):127-31.

Herpes simplex virus infections are encountered often due to their ubiquitous nature. Common sites involved include skin, mucous membrane, genitalia, eye and the nervous system. HSV infection of the central nervous system can be life threatening. Little is known...

The levels of soluble nucleotides in wheat aleurone tissue.

Plant physiology

Collins GG, Jenner CF, Paleg LG.
PMID: 16657969
Plant Physiol. 1972 Mar;49(3):398-403. doi: 10.1104/pp.49.3.398.

The content of soluble nucleotides in aleurone layers isolated from mature wheat (Triticum aestivum var. Olympic) grain was investigated. The most abundant nucleotides were adenosine triphosphate, uridine triphosphate, and uridine diphosphoglucose. Smaller amounts of guanosine triphosphate, cytidine triphosphate, adenosine...
