Previous epidemiological studies have indicated an increased risk of breast cancer associated with digitalis medication, though results are inconsistent. We performed this systematic review of available epidemiological studies to clarify the association between digitalis use and the risk of breast

It was the aim of the present study (1) to characterize the influence of Na+/K(+)-ATPase inhibition by the digitalis glycoside ouabain on both spontaneous and nicotine-evoked norepinephrine release from the human heart; and (2) to further investigate the role of glycoside-induced changes in [Na+]i

Amyloplastid DNA was extracted from the Scrophulariaceae holoparasite Lathraea clandestina L. and then purified. An rbcL gene amplification was performed using polymerase chain reaction. Two regions of well conserved sequences in Tobacco, Spinach and Maize rbcL gene have been used as primers. PCR

Zamia furfuracea (Zamiaceae) is native of coastal Mexico. It is a popular houseplant and easy to grow outdoors in warm climates. In November 2005, a plant of Z. furfuracea, originally from Texas, was received at the Division of Plant Industry in Gainesville, FL. The plant had numerous chlorotic

Atrial premature beats seldom require an antiarrhythmic treatment; reassurance and suppression of coffee, alcohol, and tobacco generally suffice. Acute atrial fibrillation is best treated by electrical cardioversion if it induces acute cardiovascular decompensation. If it is not poorly tolerated,

The results obtained show that adrenalin, transfusion with salt solution, and the inhalation of tobacco smoke caused an increased circulation in the coronary vessels. Amyl nitrite and nitroglycerin produce the opposite effect. Digitalis, strophanthus, caffeine, and theobromine give no change in the

Inhalation of a few puffs on a cigarette increases the velocity of conduction and shortens the effective refractory period of the A-V node. These effects are attributed to adrenergic stimulation produced by minute amounts of nicotine absorbed. Wenckebach block is abolished whether induced by atrial

Most of the information which has been collected on salivary composition in different disease states (with the notable exception of that in digitalis intoxication) has proved of little practical diagnostic value. Diagnostic use of saliva has become more extensive in recent years, particularly in

Various cardiovascular drugs have been shown to have neuropsychiatric effects that can be harmful or therapeutically beneficial to patients. As an example, both sedation and mental depression have been described in patients receiving centrally acting antihypertensive drugs and beta-adrenergic

Plant cell protoplasts, derived from sexually incompatible plant species, have proved to be a good system for somatic hybridization by electrofusion. Under microgravity, an increase in fusion yield can be expected, especially if the parental cells differ markedly in size or specific density. On the

Commonly used cardiovascular medications have neuropsychiatric effects, which can be either harmful or of therapeutic benefit to patients. For example, sedation and mental depression have been described with centrally acting antihypertensive drugs and beta-adrenergic drugs, and are related to their

Chronic consumption of ethanol has deleterious effects on the cardiovascular system, as manifested by an attenuation in myocardial contractility, a reduction in cardiac output, and the induction of arrhythmia. The arrhythmogenic effect of ethanol is associated with the high incidence of sudden death

Transgenic tobacco (Nicotiana tabacum L.), licorice (Glycyrrhiza uralensis Fisher) and foxglove (Digitalis purpurea L.) were obtained with binary vector systems based on a disarmed Agrobacterium tumefaciens and on a virulent A. rhizogenes. The chimeric neomycin phosphotransferase II (NPT-II) gene
