Atovaquone is a component of Malarone, a widely prescribed antimalarial combination, that targets malaria respiration. Here we show that parasites with high-level resistance to an inhibitor of dihydroorotate dehydrogenase demonstrate unexpected atovaquone tolerance. Fortunately, the tolerance is diminished with proguanil, the second partner in Malarone. It is important to understand such "genet...
Current immunotherapy of posterior uveitis is non-specific and limited by drug toxicity and unpredictable relapses on therapy. Alternative modes of therapy being investigated using the rat model of experimental autoimmune uveoretinitis (EAU) have included the induction of tolerance with oral administration of milligram quantities of retinal antigens. In this preliminary report we demonstrate th...
Use of hematopoietic cell transplants to achieve tolerance in patients with solid organ transplants.
The goals of tolerance in patients with solid organ transplants are to eliminate the lifelong need for immunosuppressive (IS) drugs and to prevent graft loss due to rejection or drug toxicity. Tolerance with complete withdrawal of IS drugs has been achieved in recipients of HLA-matched and mismatched living donor kidney transplants in 3 medical centers using hematopoietic cell transplants to es...
The current study used 64 rats to examine the effect of context shift on tolerance to alcohol, assessed by performance on a peak-interval task. Past research has extensively studied chronic alcohol intake and the mechanisms that underlie development of tolerance to alcohol in both humans and animals (McCusker & Brown, 1990; White, Roberts, & Best, 2002). Specifically, prior research has examine...
Common cellular and molecular mechanisms are not only involved in the development of neuropathic pain caused by neurological damage but also in the occurrence of the tolerance/hyperalgesia phenomenon caused by chronic use of opioids. It seems that the activation of the neuroimmune system in the brain and spinal cord is one of the most important mechanisms involved in the initiation and mainte...
Aim: The study aim was to investigate the fitness of Iranian adolescents' risk-taking model in addiction with emphasis on family functioning and maladaptive schemas, distress tolerance and emotion regulation among Qom students. Method: The research method was descriptive-correlational of structural equations. The study population consisted of all adolescents who were studying in the second...
Abstract AIMS • To determine the expression patterns of specific ATP-binding cassette (ABC) transporters in medulloblastoma assess whether ABC play a role acquired drug resistance SHH using drug-tolerant cell line models extracellular vesicles transfer drug-tolerance and mechanism by which they do this METHOD Drug-tolerant lines were generated continuous culture drug-containing medium. trans- p...
Highly optimized tolerance (HOT) is a mechanism that relates evolving structure to power laws in interconnected systems. HOT systems arise where design and evolution create complex systems sharing common features, including (1) high efficiency, performance, and robustness to designed-for uncertainties, (2) hypersensitivity to design flaws and unanticipated perturbations, (3) nongeneric, special...
Drug addiction is likely to affect all of our lives, with any luck not through our own actions but probably because of one or more of our family and friends. Now firmly entrenched as a brain disease (Leshner, 1999; Wise, 2000), drug addiction is among the most costly such diseases in modern society. Drug addiction is most often defined as a chronically relapsing disorder in which the addict exp...
Drug allergy is one type of adverse reaction to drugs and encompasses a spectrum of hypersensitivity reactions with heterogeneous mechanisms and clinical presentations. A thorough history is essential to the management of drug allergy. Laboratory testing has a very limited role in the management of drug allergy. Graded dose challenges and procedures to induce drug tolerance might be required in...
