Pulmonary delivery of nucleic acids opens the possibility for direct treatment of lung diseases, like fibrosis, cancer, and infections. Lung retention and biodistribution of nucleic acids remain important issues for the development of suitable therapeutic approaches. Moreover, monitoring the dynamic biodistribution processes of siRNA after aerosol delivery can help in identifying bottlenecks and optimising therapeutic concepts. We investigated dynamic biodistribution events after intratracheal application of chemically stabilised siRNA labeled with near infrared emitting dye AlexaFluor750 (AF750)...

Consumer and regulatory agencies have a high concern to antibiotic residues in food producing animals, so appropriate screening assays of fast, sensitive, low cost, and easy sample preparation for the identification of these residues are essential for the food-safety insurance. Great efforts in the development of a high-throughput antibiotic screening assay have been made in recent years. Concerning the screening of antibiotic residue, this review elaborate an overview on the availability, advancement and applicability of antibiotic receptor based screening assays for the safety assessment of antibiotics usage (i...

Previously, we showed that the blockade of α1-adrenoreceptors in the median raphe nucleus (MnR) increased food intake in free-feeding rats, indicating that adrenergic mechanisms in the MnR participate in the regulation of food intake. However, the impact of such a pharmacological manipulation on other neural circuits related to food intake remains unknown. In the current study, we sought to identify forebrain regions which are responsive to α1-adrenergic receptor blockade and presumably involved in the modulation of the feeding response...

Dietary protein digestion and absorption kinetics determine the post-prandial increase in muscle protein synthesis. We recently demonstrated that body position during feeding can modulate the post-prandial rise in plasma amino acid availability. Here we investigated whether protein ingestion in an upright sitting body position accelerates gastric emptying and improves dietary protein digestion and subsequent amino acid absorption compared with feeding in a supine lying body position. In a crossover design, eight young males (26±1 y, 24...

Introduction: The U.S. Food and Drug Administration (FDA) has estimated the economic impact of Graphic Warning Labels (GWLs). By omitting the impact on tobacco consumption by pregnant women, the FDA analysis underestimates the economic benefits that would occur from the proposed regulations. There is a strong link between the occurrence of low birth weight babies and smoking while pregnant. Low birth weight babies in turn generate much higher hospital costs than normal birth weight babies. This study aims to fill the gap by quantifying the national hospital cost savings from the reductions in prenatal smoking that will arise if GWLs are implemented in the U...

The use of high-resolution MS (HRMS) is becoming popular in laboratories for the determination of pesticide residues in food commodities. The recent improvements in the instrumentation have helped to increase the number of active compounds and transformation products that can be monitored within a simple chromatographic run. However, prior to instrumental determination, it is necessary to perform a nonspecific, or generic, sample treatment that allows the efficient extraction of several compounds with very relevant differences in their physical and chemical properties...

In the USA at the beginning of this century, the average overall survival in patients with multiple myeloma was about 3 years. Around that time, three drugs (bortezomib, lenalidomide and thalidomide) were introduced for the treatment of multiple myeloma and, in 2012, carfilzomib received accelerated approval by the US Food and Drug Administration (FDA). Driven by access to better drugs, median overall survival in younger patients (aged <50 years) was >10 years by 2014. The FDA approved 14 new drugs for the treatment of cancer in 2015; four of these were approved for the treatment of myeloma (panobinostat, daratumumab, elotuzumab and ixazomib)...

INTRODUCTION: Uveitis, a leading cause of preventable blindness around the world, is a critically underserved disease in regard to the medications approved for use. Multiple immunomodulatory therapy (IMT) drugs are appropriate for uveitis therapy but are still off-label. These IMT agents, including antimetabolites, calcineurin inhibitors, alkylating agents, and biologic agents, have been designated as "orphan drugs" and are widely used for systemic autoimmune diseases or organ transplantation...

Methods for simple and fast detection and differentiation of bacterial species are required for instance in medicine, water quality monitoring, and the food industry. Here, we have developed a novel label array method for the counting and differentiation of bacterial species. This method is based on the nonspecific interactions of multiple unstable lanthanide chelates and selected chemicals within the sample leading to a luminescence signal profile that is unique to the bacterial species. It is simple, cost-effective, and/or user-friendly compared to many existing methods, such as plate counts on selective media, automatic (hemocytometer-based) cell counters, flow cytometry, and polymerase chain reaction (PCR) -based methods for identification...

The concept of food addiction is increasingly used in the academic literature and popular media to explain some forms of overweight and obesity. However, there is limited evidence on how this term is understood by and impacts overweight and obese individuals. This qualitative study investigated the views of overweight and obese individuals on food addiction, and its likely impact upon stigma, treatment-seeking, and support for public policies to reduce overeating. Semi-structured interviews were conducted with 23 overweight and obese individuals (Mage = 38, MBMI = 33, 74% female) and analysed thematically...
