The nano copper has been widely used in modern clinical medicine practice. However, it has been noticed that nano copper particles induce cell injury and toxicity. The present study was designed to determine the effect of nano copper particles on cell injury of intestinal epithelial cells (IECs) in piglets. The IECs were treated with different doses of nano copper (5, 10, 20 and 40μg/ml) for 24-48h to observe cell injury and toxicity. Cell injury was measured based on morphological and other changes including oxidative stress and genes expression...

Since about 2005 VbHC has become a prominent movement on the border between population medicine and health economics. The "value" it is aiming at is defined as health care "outcomes per dollar spent". The text focuses on the work of two prominent proponents: M.E. Porter and J.A.M. Gray. It considers background and central elements of VbHC and discusses similarities and differences between the two authors. Especially the differences raise questions that will hopefully play a role in the German discussion that is still in its infancy...

INTRODUCTION: Atrial fibrillation (AF) is the most common arrhythmia affecting patients in open heart ICU after coronary artery bypass grafting (CABG). Most cardiac surgery textbooks recommend beta blockers as the drug of choice for treating such a condition while many experienced physicians and a number of anesthesiology references offer amiodarone as the drug of choice. Therefore, because of insufficient evidence and the aforementioned controversy, we decided to conduct a study evaluating these two antiarrhythmic medicines...

Background: Vetiver is a key ingredient for the perfume industry nowadays. However, with the constant and rapid changes of personal tastes, this appeal could vanish and this sector could decline quite quickly. New dissemination paths need to be found to tap this valuable resource. Methods: In this way, its potential use in cosmetics either as an active ingredient per se (with cosmeceutical significance or presenting antimicrobial activity) has hence been explored in vitro. Results: In this contribution, we demonstrated that vetiver essential oil displays no particularly significant and innovative cosmetic potential value in formulations apart from its scent already largely exploited...

The prevalence of metabolic syndrome (MetS) in people with serious mental illness (SMI) has been well documented in the mental health literature. Despite the adoption of various guidelines for monitoring risk factors for diabetes and cardiovascular risk in this population, limited translation has occurred in actual practice (Hermes, Sernyak, & Rosenheck, 2013). The Institute of Medicine (IoM) (2009) has noted a lag time in the application of knowledge within clinical settings. Evidence-based practice was deemed as a means of improving healthcare outcomes through the use of science supported standards of care...

Human induced pluripotent stem cells (hiPSC) hold great promise in diagnostic and therapeutic applications. However, translation of hiPSC technology depends upon a means of assessing hiPSC quality that is quantitative, high-throughput, and can decipher malignant teratocarcinoma clones from normal cell lines. These attributes are lacking in current approaches such as detection of cell surface makers, RNA profiling, and/or teratoma formation assays. The latter remains the gold standard for assessing clone quality in hiPSCs, but is expensive, time-consuming, and incompatible with high-throughput platforms...

Topoisomerase I (Topo I) catalyzes topological interconversion of duplex DNA during DNA replication and transcription, and has been deemed as important antineoplastic targets. In this study, the fraction R.d-60 from ethyl acetate extracts of Rhamnus davurica showed higher inhibitory rates against SGC-7901 and HT-29 compared with the R.d-30 fraction in vitro. However, the specific active components of R.d-60 fraction remain elusive. To this end, a method based on bio-affinity ultrafiltration and high performance liquid chromatography/electrospray mass spectrometry (HPLC- ESI-MS/MS) was developed to rapidly screen and identify the Topo I inhibitors in this fraction...

Cumin is a plant of the Apiaceae family (umbelliferae) which has been used since ancient times as a medicinal plant and as a spice. The difference in the percentage of aromatic compounds in cumin obtained from different locations has led to differentiation of some species of cumin from other species. The quality and price of cumin vary according to the specie and may be an incentive for the adulteration of high value samples with low quality cultivars. An electronic nose simulates the human olfactory sense by using an array of sensors to distinguish complex smells...

Melilotus, an annual or biennial herb, belongs to the tribe Trifolieae (Leguminosae) and consists of 19 species. As an important green manure crop, diverse Melilotus species have different values as feed and medicine. To identify different Melilotus species, we examined the efficiency of five candidate regions as barcodes, including the internal transcribed spacer (ITS) and two chloroplast loci, rbcL and matK, and two non-coding loci, trnH-psbA and trnL-F. In total, 198 individuals from 98 accessions representing 18 Melilotus species were sequenced for these five potential barcodes...
