Opis:
Lung cancer is one of the most common types of cancer diagnosed, and the development of methods to image diseased lung tissue by MRI is of utmost importance. Contrast-Enhanced Magnetic Resonance Imaging (CE-MRI) was used to noninvasively evaluate spin-spin relaxation time, T1, of lung cell cultures infused with various clinical gadolinium-based contrast media for imaging. In this study we used a clinical 1.5 Tesla scanner and the contrast agents: Omniscan, MultiHance, Gadovist and ProHance. A significant five-fold reduction of T1 relaxation time was obtained.

Opis:
Introduction. Cytisine, Cytisinum (C11H14N2O), is an organic chemical compound. Cytisine is heterotricyclic compound that is the toxic principle in Laburnum seeds and is found in many members of the Fabaceae (legume, pea or bean) family. Aim. The aim of the study is to measure the influence of water on the form of drug in the magnetic field 1.5 Tesla. Material and methods. For this purpose, magnetic resonance imaging tests were performed to check the solubility of pure cytisine, Desmoxan tablets and Tabex capsules. Results. From a pharmacological point of view, both Desmoxan tablets and Tabex capsules should exert the same effect on the human body, this is due to the identical content of the active substance, in this case cytisine (1.5 mg). Conclusion. The differences in the results obtained may be related to additional excipients that contain medications, but it is believed that they should not have a negative impact on the action of the active substances.

Opis:
Tobacco use is a leading cause of preventable mortality worldwide. New cost-effective smoking cessation treatments are needed especially in some low-to-middle income countries where smoking rates are rising, and current pharmacotherapy treatments remain cost-prohibitive. Since the 1960’s, cytisine has been used as an effective nicotine substitution agent to aid in smoking cessation albeit limited to a selected few Eastern/Central Europe and Central Asian countries. Cytisine is a biologically active alkaloid of plant origin and is known to be a ligand of nicotinic acetylcholinergic receptors (nAChRs). For several decades, the properties of cytisine have been investigated and reported in the biomedical and pharmaceutical literature. Due to the beneficial impact of cytisine on smoking cessation and its costly multistep synthesis, there is a growing interest in extraction from natural sources as well as in analytical identification and quantification for clinical medicine and forensic toxicology. In this paper, we present several current analytical approaches to cytisine extraction and identification from biological samples of plant and human origin. The development of extraction techniques will allow for the widespread use of the drug in experimental and clinical pharmacology, toxicology and forensic medicine.

Introduction. The use of Quantitative Magnetic Resonance Imaging to drug monitoring in vitro or in vivo can provides a powerful means to map the effects of drugs on tissue activity. Aim. The purpose of this study was to measure relaxation time of antibody phantom. For this purpose, infliximab sample was used. Material and methods. The selected methods to detect relaxation time of antibody was Magnetic Resonance Imaging technique. We detected spin-lattice (T1 ) relaxation time and discuss differences where compare to water. Results. The measurements ofspin-lattice (T1 ) relaxation time showed significant differences. The results obtained in phantom indicate that we can use this result for measurements of relaxation time in vitro. Conclusion. Infliximab is approved for severe cases of rheumatoid arthritis, together with methotrexate, for pronounced psoriasis and psoriasis-arthritis, ankylosing spondylitis as well as for chronic inflammatory bowel disease. We conclude, that Quantitative Magnetic Resonance Imaging can be used to monitor drug effects

Opis:
Over the past few decades, magnetic resonance imaging (MRI) has proven to be extremely successful in medical applications. More recently, the biomedical applications of MRI have been gaining more use in the field of clinical pharmacy. In 1977, perfluorocarbon compounds (PFC), which form emulsions that can carry drugs, were analyzed by 19F MRI and emulsified PFC compounds have been investigated as potential blood substitutes since the early 1960s and now a wide variety of PFC compounds are currently available as 19F MRI biomarkers. Molecules with 19F substituents are particularly attractive for use in drug tracking by 19F MRI due to 100% 19F abundance, high 19F MRI sensitivity (0.83 relative to 1H MRI) and an impressively large chemical shift range (400 ppm). Another benefit in the use of 19F MRI is a zero background signal in biological samples due to lack of endogenous fluorine. Therefore, drugs containing fluorine atom have potential for 19F MRI imaging drug delivery to tissue. This article will review recent developments in the use of 19F MRI in imaging drug delivery to tissue and individual cells.

Opis:
Despite continuous scientific and technological advances in MR imaging, MR perfusion methods have not yet been widely deployed for routine clinical diagnostics. This is especially true for ASL (arterial spin labelling) methods used to evaluate cerebral perfusion. This method does not require a contrast agent, as new discoveries about gadolinium accumulation in the cerebellum and brain nucleus appear to be a valuable asset and provide the opportunity to be more widely deployed in clinical practice. The aim of this paper is to present the historical determinants of the development of MR perfusion techniques, the disadvantages and advantages and possible clinical applications and prospects of ASL development. Both historical articles published on MR in the 1990s and current research between 2006-2016 have been reviewed. The authors present in the work the MR perfusion method focusing on issues related to arterial spin labeling (ASL). Historically CASL (continuous ASL) and PCSL (pulsed ASL) techniques have been described and the pseudocontinuous ASL (pseudocontinuous ASL) 3D technique presents its technical and methodological considerations, advantages and disadvantages over previous methods. The methods of test protocol optimization and accompanying artifacts, as well as possible clinical applications and development perspectives, have been described.
