BLOOD LEVEL OR PHARMACOLOGICAL RESPONSE?

Brain imaging findings predict blood pressure response to pharmacological treatment.

Hypertension appears to alter brain morphology, as well as the cerebrovascular support for information processing. Because these effects might reflect progressive effects of essential hypertension on the brain, we asked whether structural and functional brain indices would predict the success of pharmacological treatment of hypertension among 45 previously unmedicated individuals. After initial...

Lower oesophageal sphincter response to gastrin--pharmacological or physiological?

The response of the lower oesophageal sphincter (LOS) to intragastric instillation of protein was assessed in 10 healthy volunteers. Sphincter pressures were measured by a rapid pull-through technique and serum gastrin concentrations during each test were determined by radioimmunoassay. Despite stimulation of gastrin release by protein instillation, no significant change in LOS pressure was obs...

Blood lead level in opium abuse. Which is more dangerous? Opium smoking or opium ingestion?

Self-Regulation of Blood Oxygenation Level Dependent Response: Primary Effect or Epiphenomenon?

In the last decade, several studies indicated that neuronal activity can be volitionally modulated using real-time fMRI (rtfMRI) based neurofeedback. Human participants through rtfMRI paradigms can learn to regulate the blood oxygenation level dependent (BOLD) response in several localized cortical and subcortical regions (for extended reviews see Caria et al., 2012; Weiskopf, 2012; Sulzer et a...

Investigation on artificial blood or substitute blood replace the natural blood

Blood is a liquid tissue in which dissolved with abundant chemical factors and millions of different cells The reduction of unwanted side effects, especially diseases that emerge through blood such as HIV and hepatitis, has a significant role for modern medicine of transfusion and transplantation. The issues and costs of human blood collection and storage, direct this procedure towards t...
