Salem MH, Mekkawy MY, Ahmed NA, Abdel-Aziz IY, Mohamed AA, El-Oksh HA, Pursel VG.
PMID: 16727104
Theriogenology. 1992 May;37(5):1061-74. doi: 10.1016/0093-691x(92)90104-y.

Ejaculated washed ram spermatozoa showed consistent increases in the intracellular concentration of cyclic 3', 5'-adenosine monophosphate (cAMP) after incubation for 15 minutes with the phosphodiesterase (PDE)-inhibitors, theophylline and caffeine. In vitro addition of cAMP or PDE-inhibitors to ram semen...

1. The effects of azaserine and nicotinamide, agents which inhibit and stimulate hepatic NAD synthesis respectively, on the content of NAD(+) and NADH in isolated rat islets of Langerhans incubated in vitro were studied. The effects of these compounds...

CTAD as a universal anticoagulant.

Journal of automated methods & management in chemistry

Yokota M, Tatsumi N, Tsuda I, Nishioka T, Takubo T.
PMID: 18924886
J Autom Methods Manag Chem. 2003;25(1):17-20. doi: 10.1155/S1463924603000038.

The feasibility of CTAD (a mixture of citrate, theophylline, adenosine and dipyridamole) as a new anticoagulant for medical laboratory use was studied prospectively. Whole blood anticoagulated with CTAD exhibited results very similar to those of blood anticoagulated with EDTA...

Prediction of selectivity coefficients of a theophylline-selective electrode using MLR and ANN.

Talanta

Riahi S, Mousavi MF, Shamsipur M.
PMID: 18970631
Talanta. 2006 May 15;69(3):736-40. doi: 10.1016/j.talanta.2005.11.010. Epub 2005 Dec 13.

The selectivity coefficient of 24 interfering compounds (drugs, amino acids and organic compounds) of a theophylline-selective electrode was predicted using an artificial neural network (ANN). The multiple linear regression (MLR) technique was used to select the descriptors as inputs...

Determination of theophylline in plasma by oxidation at the stationary carbon-paste electrode.

Talanta

Munson JW, Abdine H.
PMID: 18962243
Talanta. 1978 Apr;25(4):221-2. doi: 10.1016/0039-9140(78)80008-3.

A method for the determination of the concentration of theophylline in plasma at therapeutic levels is described. The method is based on the oxidation of theophylline at the stationary carbon-paste electrode and involves a simple extraction procedure and differential...

BioDrugs : clinical immunotherapeutics, biopharmaceuticals and gene therapy

Steenhuis TJ, Landstra AM, Verberne AA, van Aalderen WM.
PMID: 18031192
BioDrugs. 1999 Dec;12(6):431-8. doi: 10.2165/00063030-199912060-00003.

Nocturnal symptoms of asthma such as coughing, wheezing, dyspnoea and dyspnoea on awakening are common in children with asthma. This is an important issue since nocturnal symptoms may have a negative influence on the child's life, affecting, for example,...
