The <i>Sleeping Beauty</i> transposon system has been extensively tested for integration of reporter and therapeutic genes <i>in vitro</i> and <i>in vivo</i> in mice. Dogs were used as a large animal model for human therapy and minimally invasive infusion of DNA solutions. DNA solutions were delivered into the entire liver or the left side of the liver using balloon catheters for temporary occlusion of venous outflow. A peak intravascular pressure between 80 and 140 mmHg supported sufficient DNA delivery in dog liver for detection of secretable reporter proteins...

BACKGROUND: Feed costs are a major expense in the production of beef cattle. Individual variation in the efficiency of feed utilization may be evident through feed efficiency-related phenotypes such as those related to major energetic sinks. Our objectives were to assess the relationships between feed efficiency with liver morphometry and metabolic blood profile in feedlot beef cattle. METHODS: Two populations (A = 112 and B = 45) of steers were tested for feed efficiency...

Multiple myeloma is a clonal disorder of plasma cells that is currently considered incurable. CD38 is a 46 kDa type II transmembrane glycoprotein that is highly expressed on myeloma cells. Daratumumab is a first in-class human IgG1 monoclonal antibody that targets CD38, and has antimyeloma effects through several mechanisms. Single-agent trials show surprising activity in heavily pretreated myeloma patients. Trials in the relapsed setting, where daratumumab is added to lenalidomide and dexamethasone or bortezomib and dexamethasone, have demonstrated significantly improved progression-free survival with acceptable toxicity...

N-substituted pantothenamides (PanAms) are pantothenate analogues with up to nanomolar potency against blood-stage Plasmodium falciparum (the most virulent species responsible for malaria). Although these compounds are known to target coenzyme A (CoA) biosynthesis and/or utilization, their exact mode of action (MoA) is still unknown. Importantly, PanAms that retain the natural β-alanine moiety are more potent than other variants, consistent with the involvement of processes that are selective for pantothenate (the precursor of CoA) or its derivatives...

BACKGROUND Drug-induced immune hemolytic anemia (DIIHA) is a rare condition that may result from the administration of an antibiotic, most notably the cephalosporin class, commonly used in both the adult and pediatric populations. A delay in recognition by a provider may lead to continuation of the offending agent and possibly result in fatal outcomes. CASE REPORT We report the case of a 65-year-old woman on ceftriaxone infusions after being diagnosed with acute mitral valve endocarditis 3 weeks prior, which presented with severe anemia and bilateral transient vision loss...

BACKGROUND: Patients undergoing liver transplantation frequently but inconsistently require massive blood transfusion. The ability to predict massive transfusion (MT) could reduce the impact on blood bank resources through customization of the blood order schedule. Current predictive models of MT for blood product utilization during liver transplantation are not generally applicable to individual institutions owing to variability in patient population, intraoperative management, and definitions of MT...

Electrical stimulation of subthalamic nuclei (STN) is a widely used therapy in Parkinson's disease (PD). While deep brain stimulation (DBS) of the STN alters the neurophysiological activity in basal ganglia, the therapeutic mechanism has not been established. A positron emission tomography (PET) study of cerebral blood flow (CBF) during speech production in PD subjects treated with STN-DBS found significant increases in global (whole-brain) CBF.(1) That study utilized a series of whole-slice regions of interest to obtain global CBF values...

The development of an immunoassay for a low-molecular-weight drug first requires the identification of specific antibodies that do not cross-react with the drug's metabolites. If two antibodies can simultaneously recognize the entire structure of the drug, we can then utilize them to establish an ultra-specific sandwich ELISA, free from interference due to the metabolic products of the drug. This paper reports an ultra-specific and sensitive sandwich ELISA for determination of the tyrosine kinase inhibitor imatinib using two anti-imatinib antibodies...

BACKGROUND: The neonatal innate immune system differs to microbial infection both quantitatively and qualitatively when compared with adults. Here, we provide the first genome-wide ex-vivo expression profile of umbilical cord blood (UCB) neutrophils from full-term infants prior to and in response to whole-blood lipopolysaccharide (LPS) stimulation. Additionally, we provide cytokine expression prior to and following LPS stimulation. The genomic expression and cytokine profile are compared with LPS-stimulated whole blood from healthy adult subjects (HC)...

Bisphenol A (BPA) is an estrogenic chemical used in the production of polycarbonate plastics and epoxy resins. Our earlier studies have demonstrated that BPA is a potent reproductive and genotoxic agent and affects the normal physiological functions. The objective of this study was to evaluate whether exposure to BPA induces oxidative stress. The male Holtzman rats were orally gavaged with BPA (0.01 mg and 5.0 mg/kg/bw) over the period of 6 days. Animals were euthanized by cervical dislocation at the end of the treatments; bone marrow cells and blood lymphocytes were aspirated; testis and epididymis were collected, immediately frozen in liquid nitrogen, and stored at -80°C...

Historically, blood substitutes were under development that would provide oxygen carrying capacity as well as fluid replacement for both trauma and surgical indications. Their development was halted by the inability of the products to deliver therapeutic amounts of oxygen targeted to hypoxic tissue as well as from the inherent toxicity of the molecules. This led to the concept of an oxygen therapeutic that would be targeted for indications caused by anemia/ischemia/hypoxia but would not exhibit the toxicity that plagued earlier products...

Prolonged normothermic ex-vivo heart perfusion (NEVHP) could transform cardiac transplantation. To help identify perfusate components that might enable long-term perfusion, we evaluated the effects of cross-circulated whole blood and cross-circulated plasma from a live paracorporeal animal on donor porcine hearts preserved via NEVHP. Standard perfusion (n=40) utilized red blood cell/plasma perfusate and Langendorf technique for a goal of 12 hours. Cross-circulation groups used a similar circuit with the addition of cross-circulated venous whole blood (XC-Blood; n=6) or cross-circulated filtered plasma (XC-Plasma; n=7) between a live paracorporeal pig under anesthesia and the perfusate reservoir...

BACKGROUND: Oxidative stress has long been linked to neuronal cell death in many neurodegenerative diseases. Antioxidant conventional supplements are poorly effective in preventing neuronal damage caused by oxidative stress due to their inability to cross the blood brain barrier. Hence the use of molecules extracted from plants and fruits such as phenolics, flavonoids, and terpenoids compounds constitute a new wave of antioxidant therapies to defend against free radicals. OBJECTIVE: In this study we examined the effects of punicalagin, a ellagitannin isolated from the pomegranate juice, on a rat adrenal pheochromocytoma cell line, treated with hydrogen peroxide, evaluating the viability, oxidation potential, mitochondrial function, and eventual apoptosis...

Attention-deficit/hyperactivity disorder (ADHD) is a complex neurobehavioral disorder affecting millions of patients worldwide. Effective treatments have been available for more than 60 years in the form of immediate-release (IR) stimulants However, stimulants have a high risk for abuse and are associated with adverse effects Including elevated blood pressure and heart rate, insomnia and decreased appetite. IR formulations also require multiple daily dosing. The search for improved safety, tolerability and convenience has led to the development of multiple extended-release (ER) stimulant and non-stimulant formulations...

Heat stress (HS) decreases milk protein synthesis beyond what would be expected based on the concomitant reduction in feed intake. The aim of the present study was to evaluate the direct effects of HS on milk protein production. Four multiparous, lactating Holstein cows (101 ± 10 d in milk, 574 ± 36 kg of body weight, 38 ± 2 kg of milk/d) were individually housed in environmental chambers and randomly allocated to 1 of 2 groups in a crossover design. The study was divided into 2 periods with 2 identical experimental phases (control phase and trial phase) within each period...
