  • The role of the ATP-binding cassette ABCB1 in mediating the resistance to chemotherapy in many forms of cancer has been well established. The pro-tein is also endogenously expressed in numerous barrier and excretory tissues, thereby regulating or impacting on drug pharmacokinetic profiles.

  • We live in a world heavily populated by microorganisms of astonishing diversity. Most of these exist in our external environment but certain classes are normally harboured within our bodies, especially colonising mucosal surfaces. Depending on the circumstances, infectious disease can arise from organisms living exogenously or endogenously, and a knowledge of common pathogens at specific sites often provides a good basis for rational initial therapy.

  • Infection is a major category of human disease and skilled management of antimicrobial drugs is of the first importance.The term chemotherapy is used for the drug treatment of parasitic infections in which the parasites (viruses, bacteria, protozoa, fungi, worms) are destroyed or removed without injuring the hostThe use of the term to cover all drug or synthetic drug therapy needlessly removes a distinction which is convenient to the clinician and has the sanction of long usage.

  • Among the subspecialties of internal medicine, medical oncology may have had the greatest impact in changing the practice of medicine in the past four decades, as curative treatments have been identified for a number of previously fatal malignancies such as testicular cancer, lymphomas, and leukemia. New drugs have entered clinical use for disease presentations previously either untreatable or amenable to only local means of therapy, such as surgery and irradiation.

  • Malaria, caused by four species of Plasmodium, of which Plasmodium falciparum is the most dangerous, remains the world's most devastating human parasitic infection. This chapter deals with the properties and uses of important drugs used to treat and prevent this infection. Highly effective agents that act against asexual erythrocytic stages of malarial parasites responsible for clinical attacks include chloroquine, quinine, quinidine, mefloquine, atovaquone, and the artemisinin compounds.

  • Velocity encoded phase-contrast magnetic resonance imaging (VE-PC MRI) is another imaging technique used to noninvasively measure Achilles tendon strain and changes in its force-displacement relationship concomitant with chronic unloading and subsequent recuperation. This technique will be reviewed in terms of its ability to quantify the Achilles tendon Young’s modulus (MPa) from a stress-strain curve.

  • Hospitals, by their very nature, are dangerous places. Sick and infected patients are clustered together in one institution, often in close proximity to those who are immunosuppressed due to recent surgery, chemotherapy or transplantation. Contact between these various patient groups is easily achieved via the hands of healthcare workers (HCWs), use of shared equipment or the hospital’s air handling system.

  • Contact between mothers inside prison and their children outside prison may be severely and/or inappropriately restricted. In some countries, mothers are temporarily separated (such as by stopping visits) from the children to punish the mother (Robertson, 2008). Children are a life-sustaining force for many prisoners, and breaking up the bond between the mother and child is often punishment of the worst kind for the mother (United Nations Office on Drugs and Crime, 2008) and strongly affects her physical and mental health. It also punishes the child, who has done nothing wrong. ...

  • For the last 60 or so years the chemotherapy of bacterial infections has been dominated by natural products and their semi-synthetic variants. Although the term antibiotic was initially used exclusively to describe those anti-bacterials of natural or semi-synthetic origin, it has become broadened in common usage to include antibacterial agents of purely synthetic origin as well. The emphasis of this chapter will be on the discovery of novel prototype structures that represent the different classes of antibiotic e.g.

  • Recent reductions in cancer mortality are due in part to risk reduction behaviors like smoking cessation and more strongly to early detection of cancer coupled with appropriate therapy. Yet, there are no validated molecular biomarker tests for the early detection of any cancer (see Table I). Among the list of Food and Drug Administration (FDA)-approved biomarkers, none have been approved for cancer early detection and screening.

  • There is a pervasive perception among providers that treating patients with TB on an outpatient basis will lead to increased TB transmission. With the advent of modern antituberculosis chemotherapy, admission to the hospital has been shown not to be necessary for effective treatment of TB. Studies have shown that, not only does outpatient treatment of TB achieve cure rates comparable to inpatient care, outpatient therapy is not associated with an increase in TB transmission in the community.

  • A number of drugs used in cancer chemotherapy induce oxidative stress by generation of oxygen free radicals (ROS) which might be an alternative mechanism for their cytotoxic effect via indu-cing apoptosis. In order to clarify the roles of antioxidants in chemotherapy, we investigated Quercetin (3,3’,4’,5,7-pentahyd-roxyflavone) and N-acetylcysteine (NAC) in different cell types treated with anticancer drugs. We studied cytotoxic activity of Topotecan alone and/or in combination with Quercetin in two human breast cancer cell lines, MCF-7 and MDA-MB-231. ...

  • Ovarian cancer is the leading cause of death among women with gynecologic malignancies in the United States. Advanced ovarian cancers are difficult to cure with the current available chemotherapy, which has many associated systemic side effects. Doxorubicin is one such chemotherapeutic agent that can cause cardiotoxicity. Novel methods of delivering chemotherapy without significant side effects are therefore of critical need.

  • The field of antiviral therapy—both the number of antiviral drugs and our understanding of their optimal use—continues to lag behind the field of antibacterial drug treatment, in which 70 years of experience have now been accumulated, but significant progress has been made in recent years on new drugs for several viral infections. The development of antiviral drugs poses several challenges. Viruses replicate intracellularly and often employ host cell enzymes, macromolecules, and organelles for synthesis of viral particles.
