Thromboelastography (TEG) has been used for decades to guide transfusion therapy during cardiac and hepatic surgeries. Renewed interest and improved technology have led to wider applications of TEG in other areas of hemostasis. To correctly interpret the data generated and to validate outcomes, it is important to improve the understanding of the differences in the currently available assay procedures, the issues related to sample activation, and the importance of the use of appropriate controls. Current TEG assays use a variety of samples and can vary slightly in the procedures...

Anti-phospholipid syndrome is a complex and severe clinical situation, associated with symptoms such as recurrent thrombosis, arterial or venous, at any site, pregnancy loss, and other related syndromes. These clinical burdens, are highly variable from patient to patient, and are associated with biological abnormalities, such as the presence of the Lupus Anticoagulant or phospholipid dependent antibodies, confirmed on two occasions at least 12 weeks apart. From the diagnosis standpoint, both, functional (clotting) or immunological assays, are difficult to standardize and to optimize, due to the absence of reference material, or a characteristic clinical group, and international reference preparations...

The gynecological cancer mortality rate, including cervical, ovarian, vaginal and vulvar cancers, is more than 20,000 annually in the US alone. In many countries, including the US, external-beam radiotherapy followed by high dose rate brachytherapy is the standard-of-care. The superior ability of MR to visualize soft tissue has led to an increase in its usage in planning and delivering brachytherapy treatment. A technical challenge associated with the use of MRI imaging for brachytherapy, in contrast to that of CT imaging, is the visualization of catheters that are used to place radiation sources into cancerous tissue...

BACKGROUND: Current clinical research and practice requires interoperability among systems in a complex and highly dynamic domain. There has been a significant effort in recent years to develop integrative common data models and domain terminologies. Such efforts have not completely solved the challenges associated with clinical data that are distributed among different and heterogeneous institutions with different systems to encode the information. Currently, when providing homogeneous interfaces to exploit clinical data, certain transformations still involve manual and time-consuming processes that could be automated...

Reliable measurement of total testosterone and estradiol is critical for their use as biomarkers of hormone-related disorders in patient care and translational research. We developed and validated a mass spectrometry method to simultaneously quantify these analytes in human serum without chemical derivatization. Serum is equilibrated with isotopic internal standards and treated with acidic buffer to release hormones from their binding proteins. Lipids are isolated and polar impurities are removed by two serial liquid-liquid extraction steps...

The term "vitamin D" refers to two chemical compounds - ergosterol, or vitamin D2, and cholecalciferol, or vitamin D3. Active vitamin D3 is correctly regarded as a neurohormone due to its pleiotropic biological activities. Although the relation between vitamin D and calcium-phosphorus metabolism has never been discussed, the knowledge on many other roles vitamin D plays is growing fast. Briefly, vitamin D immunomodulation includes attenuation and stimulation of Th1 and Th2 cell proliferation, respectively. Similarly, vitamin D can induce or inhibit the synthesis, secretion, and release of anti- inflammatory (IL-4 and IL-10) and pro-inflammatory (IL-1, TNF-α, IFN-γ) cytokines, respectively...
