There are many examples of branching networks in biology. Examples include the structure of plants and trees as well as cardiovascular and bronchial systems. In many cases these networks are self-similar and exhibit fractal scaling. In this paper we introduce the Tokunaga taxonomy for the side branching of networks and his parameterization of self-similar side-branching. We introduce several ex...

Hydrogen sulfide (H(2)S) is now recognized as an important signaling molecule and has been shown to have vasodilator and cardio-protectant effects. More recently it has been suggested that H(2)S may also act within the brain to reduce blood pressure (BP). In the present study we have demonstrated the presence of the H(2)S-producing enzyme, cystathionine-β-synthase (CBS) in the rostral ventrolat...

Background: Reduced productivity due to cardiovascular disease in horses known as the third. Today, a number of drugs with different properties for the treatment of cardiovascular disease in horses which used when considering the need for newer drugs and their side effects are felt. Numerous studies on the effects of cardiovascular drugs and their effects have been carried out to examine the ef...

onsteroidal anti-inflammatory drugs (NSAIDs) are widely prescribed but can have serious gastro inal (GI) and cardiovascular side effects, which have led to the withdrawal of some of these d ontinuing uncertainty about the best approach to patients requiring NSAID therapy, particularly i ith GI or cardiovascular risk factors. To define the risks to the GI and cardiovascular systems a ith NSAID t...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely prescribed but can have serious gastrointestinal (GI) and cardiovascular side effects, which have led to the withdrawal of some of these drugs and continuing uncertainty about the best approach to patients requiring NSAID therapy, particularly in those with GI or cardiovascular risk factors. To define the risks to the GI and cardiovascula...

One of the most feared repercussions of type 2 diabetes mellitus is the risk of adverse cardiovascular outcomes. The current antidiabetic agents on the market have had difficulty in showing cardiovascular outcome improvement. The EMPA-REG OUTCOME trial studied the sodium-glucose cotransporter 2 inhibitor empagliflozin in type 2 diabetic patients at high risk of cardiovascular events. The trial ...

Background: Induction of anesthesia in patients that undergo cardiac surgery has more risk than others, because of specific cardiovascular effects of the anesthetic drugs and the preoperative state of these patients, so the hemodynamic stability is very important in these patients. It seems that midazolam have less cardiovascular side effects than thiopentone. In this study, the effects of mid...

The use of atypical antipsychotic agents has rapidly increased in the United States and worldwide in the last decade. Nonetheless, many health care practitioners do not appreciate the significance of the cardiovascular side effects that may be associated with their use and the means to minimize them. Thus, atypical antipsychotic medications can cause cardiovascular side effects such as arrhythm...

INTRODUCTION Through effects of catecholamines upon the heart, blood vessels and platelets, sympathoadrenal hyperactivity contributes to the development of cardiovascular diseases in elderly depressed patients. To assess the cardiovascular effect of Citalopram in elderly depressed patients, data from an open multicenter study in Belgium and Luxembourg, in which a total of 811 patients were eval...
