A method and an apparatus for estimating a geometric thickness of a breast in mammography/tomosynthesis or in other x-ray procedures, by imaging markers that are in the path of x-rays passing through the imaged object. The markings can be selected to be visible or to be invisible when the composite markings/breast image is viewed in clinical settings. If desired, the contribution of the markers to the image can be removed through further processing. The resulting information can be used determining the geometric thickness of the body being x-rayed and thus setting imaging parameters that are thickness-related, and for other purposes. The method and apparatus also have application in other types of x-ray imaging.

The present invention is directed to the identification of predictive markers that can be used to determine whether patients with cancer are clinically responsive or non-responsive to a therapeutic regimen prior to treatment. In particular, the present invention is directed to the use of certain individual and/or combinations of predictive markers, wherein the expression of the predictive markers correlates with responsiveness or non-responsiveness to a therapeutic regimen. Thus, by examining the expression levels of individual predictive markers and/or predictive markers comprising a marker set, it is possible to determine whether a therapeutic agent, or combination of agents, will be most likely to reduce the growth rate of tumors in a clinical setting.

Apparatus and method for using a cooled fluid to be introduced into the lungs as a heat exchange which as a result of the circulatory system of the body, lowers the temperature of the brain as well as the temper of the body in general. In instances where cardiopulmonary arrest occurs and CPR is delayed due to the clinical setting in which the arrest takes place, the rapid induction of brain hypothermia by liquid pulmonary lavage secures valuable time for the subsequent application of CPR techniques. The method can be used on any elective hypothermic surgery.

An optimization model calculates specific scanner settings needed to attain target image quality at the minimum radiation dose possible. An automated system processes the image and dose data according to the mathematical models and stores and displays the information, enabling verification and ongoing monitoring of consistent dose optimization.

Life-threatening hepatotoxicity in the setting of acetaminophen overdose is due to depletion of glutathione (GSH), a vital cysteine-containing tripeptide that protects cells and organs against oxidant injury. Rapid administration of N-acetylcysteine (NAC), which provides the cysteine necessary to replenish the depleted GSH, is the standard of care for preventing injury in acetaminophen overdose. Beneficial effects of NAC treatment have also been demonstrated in respiratory, cardiovascular, endocrine and infectious and other diseases. In fact, over fifty randomized placebo-controlled trials conducted in diverse clinical settings document positive responses to NAC treatment. The present invention relates to cysteine/glutathione (GSH) deficiency as a previously unrecognized clinical entity that can complicate the course of commonly encountered diseases and methods of treatment of this generalized deficiency involving administering N-acetylcysteine (NAC) or a pharmaceutically acceptable salt or derivative to a subject in need thereof and monitoring the subjects appropriate glutathione blood levels as needed.
