Acetaminophen induces the mitochondrial permeability transition (MPT) in hepatocytes. Reactive oxygen species (ROS) trigger the MPT and play an important role in AAP-induced hepatocellular injury. Because iron is a catalyst for ROS formation, our aim was to investigate the role of chelatable iron in MPT-dependent acetaminophen toxicity to mouse hepatocytes. Hepatocytes were isolated from fasted...
Footpad infection of C3HeB/FeJ mice with Leishmania amazonensis leads to chronic lesions accompanied by large parasite loads. Co-infecting these animals with L. major leads to induction of an effective Th1 immune response that can resolve these lesions. This cross-protection can be recapitulated in vitro by using immune cells from L. major-infected animals to effectively activate L. amazonensis...
In this work, we study the inconsistency problem of EKF-based SLAM from the perspective of observability. We analytically prove that when the Jacobians of the process and measurement models are evaluated at the latest state estimates during every time step, the linearized error-state system employed in the EKF has observable subspace of dimension higher than that of the actual, nonlinear, SLAM ...
Two types of antisera were tested, namely, conventional antileukemia serum (ALKS), prepared by immunization of rabbits with mouse leukemia cells, and antileukemia normal antigen-blocked serum (ALK-NABS), prepared by immuniza tion of rabbits with a mixture of mouse leukemia cells plus normal antigen-blocking serum (NABS). The latter was raised in rabbits by immunization with normal mouse lymphoi...
The global tuberculosis (TB) epidemic and the spread of multi- and extensively-drug resistant strains of Mycobacterium tuberculosis (M.tb) have been fueled by low adherence to following lengthy treatment protocols, and the rapid spread of HIV (Human Immunodeficiency Virus). Persistence of the infection in immunocompetent individuals follows from the ability of M.tb to subvert host immune respon...
The objectives of this study were to determine 1) the changes in endothelial cell adhesion molecule expression that occur in a clinically relevant model of sepsis and 2) the dependence of these changes on endotoxin [lipopolysaccharide (LPS)]. The dual radiolabeled monoclonal antibody technique was used to quantify the expression of E- and P-selectin in LPS-sensitive (C3HeB/FeJ) and LPS-insensit...
Peroxynitrite may be involved in acetaminophen-induced liver damage. However, it is unclear if peroxynitrite is generated in hepatocytes or in the vasculature. To address this question, we treated C3Heb/FeJ mice with 300 mg/kg acetaminophen and assessed nitrotyrosine protein adducts as indicator for peroxynitrite formation. Vascular nitrotyrosine staining was evident before liver injury between...
BACKGROUND Clinical studies suggest that acute inflammation in patients with elevated heart rate (HR) increases morbidity and mortality. The SJL/J (SJL) inbred mouse strain is a unique genetic model that has higher HR and systemic and vascular inflammation compared with C3HeB/FeJ (C3HeB) mice. The goal of this study was to investigate the role of stress on cardiac and vascular complications bet...
Investigations were performed to elucidate changes in normal syngeneic recipients after they received tumor-sensitized cells. Transfer of regional or nonregional lymph node cells or spleen cells from tumor-bearing inbred C3HeB/FeJ mice to normal syngeneic recipients caused the recipients to produced bone marrow, which mediated in vitro cytolysis of immunizing tumor target cells. This finding wa...
Acetaminophen (AAP) overdose causes formation of peroxynitrite in centrilobular hepatocytes. Treatment with glutathione (GSH) after AAP accelerated recovery of mitochondrial GSH levels, which scavenged peroxynitrite and protected against liver injury at 6 h. The objective of this investigation was to evaluate whether GSH treatment has a long-term protective effect against AAP-induced injury and...
