Mifepristone remains the gold standard since it has been in clinical use as single doses for pregnancy termination for almost a quarter of a century and considerable experience has been accumulated. Nevertheless very few long-term, randomized placebo-controlled studies have been reported. PAs and SPRMs which are undergoing clinical trials are shown in Table 7.1.

Metabolites in human blood are closely associated with the state of an individual s health. Determination of metabolites is critical in clinical diagnosis, since they can serve as a criterion for judging the severity of the sickness. Of these metabolites, glucose, lactate and urea are most frequently determined. Special attention to determination of glucose in blood is due to the fact that diabetes is well known as a dangerous and widespread disease that results in a high glucose concentration in the blood. Some other effects of metabolites, such as urea and lactate, on shock, respiratory insufficiency, and heart and kidney diseases are understood to some extent. 

Pedicle screw fixation for correction of spinal deformities has become the standard of care for stabilization of the thoracic and lumbar spine, where precise screw placement is essential to avoid injury to adjacent neural structures. However, the techniques currently available for planning such interventions are not optimal. Until recently, such procedures were 

Anatomically, target locations of LP and El are very close to each other, so the surgical access or passage way for these two procedures is quite similar. The target site for LP is the subarachnoid space, sitting just below 

The facet joints are located between two vertebrae at the lateroposterior aspect of the spinal column. They are paired synovial joints formed by the articulation of the inferior articular processes of one vertebra with the superior articular processes of the vertebra below. Each joint is bordered medially and anteriorly by the ligamentum flavum and posteriorly by the multifidus muscle. The orientation of the facet joint varies across the column, thus imderstanding the exact anatomical orientation would facilitate the insertion of the needle. 

The standard of care for both the LP and El is the blind technique, relying solely on the tactile sensation and the experience of the medical practitioner. Once the correct intervertebral level is determined, and the appropriate interspace is located by palpation, the spinal needle is advanced incrementally through the tissue until there is a give tactile sensation indicating that the needle tip has passed the ligamentum flavum. The needle is further advanced until there is a pop sensation, which indicates the dura mater has been punctured and the needle tip is now located in the subarachnoid space. The success of LP is indicated by the appearance of cerebrospinal fluid, which slowly drains through the hoUow needle due to the intracranial pressure. 

For epidurals, the needle advancement is performed with the loss of resistance technique. Typically, a Tuohy needle with syringe (fiUed with air or saline) is used to avoid accidental puncture of the dura mater. Once the needle tip has entered the ligamentum flavum, the needle is advanced while the syringe is continuously being compressed. When the loss of resistance occurs, the air/saline is injected without resistance being felt when the tip of the epidural needle reaches the epidural space.

Clinical Applications UV/Vis molecular absorption is one of the most commonly employed techniques for the analysis of clinical samples, several examples of which are listed in Table 10.7. 

Clinical Applications Perhaps the area in which ion-selective electrodes receive the widest use is in clinical analysis, where their selectivity for the analyte in a complex matrix provides a significant advantage over many other analytical methods. The most common analytes are electrolytes, such as Na+, K+, Ca +, H+, and Ch, and dissolved gases, such as CO2. For extracellular fluids, such as blood and urine, the analysis can be made in vitro with conventional electrodes, provided that sufficient sample is available. Some clinical analyzers place a series of ion-selective electrodes in a flow...

Since the pioneer work by Merigan in 1967 [1], many kinds of synthetic or natural polyanionic polymers have been examined for their biological activities [2-8], such as cytotoxicity, antiviral activity, antitumor activity, and immunomodulating activity. Although the biological results were interesting, the extent of activity for clinical application was still low. 

There were some early clinical studies of carzinophilin, both alone [131,132] and in combination with mitomycin C, in humans [133]. Despite showing promising reduction in the number of cancer cells, there were significant toxic side effects and clinical application has not been pursued any further. 

A foil discussion of each of the above categories of biological medicines and related agents covered by each of the categories is beyond the scope of this brief essay. However, ImmunoFacts is the most current and comprehensive collection of immunologic and vaccine information and is continuously updated for clinical application, including side effects [5]. 

The successful clinical application of RTK-based therapeutics in the last 8 years instigates further research to generate the next generation drugs. Thus, antisense RNAs or dominant-negative receptor mutants are being tested for their ability to reduce receptor expression.

No ligands of IP3R have yet found clinical application. Most agonists of IP3R are either modifications of DP3 or derived from adenophostin A. The only known antagonists of IP3R (e.g., heparin, 2-AJPB) are vety poorly selective. 

For patients with leukemia, the transfer of siRNA-based strategies into clinical applicability will certainly be both frustrating and time-consuming and many hurdles still have to be overcome in order to realize the therapeutic potential of siRNAs. Efficient delivery of siRNA into the leukemic stem cell and their unknown influence of the patient s immune system are the most challenging issues that need to be addressed.

This chapter will focus on the principles of hypothermic preservation of tissues of interest clinically, and discuss some of the applications of cryobiological principles to medicine. Various chapters and reviews that cover specific areas in considerable detail that are related to clinical applications of cryobiology are cited at the end of this chapter.
