Glycyrrhizin, a component of Chinese medicine licorice root, has the ability to inhibit the functions of high-mobility group box 1 (HMGB1). While glycyrrhizin is known to have anti-inflammatory activities, the underlying mechanisms by which glycyrrhizin inhibits inflammation during the development of trinitrobenzenesulfonic acid (TNBS)-induced experimental colitis are not well understood. This study systemically examined the regulatory effects of glycyrrhizin on inflammatory response in TNBS-induced murine colitis and explored the potential mechanisms involved in this process...

With the increase of new Internet platform, student access to knowledge is more and more diversified, ensuing in the challenge to the traditional classroom model. In order to be able to better attract the attention of students, and to guide the students' interest in learning, the author reform in the history of medicine electives, we push the micro letter public articles into the traditional classroom teaching. In order to enable students to actively participate in public reading and writing, a series of measures is adopted with better effect, full mobilization of the enthusiasm and interest of students, training of the abilities of the students, popularization and promotion of history of medical knowledge and mutual promotion of both teaching and learning...

BACKGROUND: Migration of healthcare workers is receiving increased attention worldwide. In Europe, the creation of a border-free labor market and its expansion with the EU enlargements of 2004, 2007, and 2013 endowed health professionals with the right to provide services and to relocate to another EU Member State. For the Romanian doctors, the EU-wide recognition of the medical degree obtained in Romania has created new opportunities, while inadequate working conditions and relatively low salaries pushed many of them to search for employment abroad...

BACKGROUND: Ombitasvir/paritaprevir/ritonavir/dasabuvir (Viekira Pak(®)) are the newest medicines approved for use in the treatment of hepatitis C virus (HCV) and are available in tablet form as an oral combination. Specifically, these agents are indicated in the treatment of HCV in patients with genotype 1 infection. Due to the therapeutic importance and increased use of Viekira Pak, proper methods for its determination in bulk and pharmaceutical formulations must be developed. RESULTS: The present study describes the development and validation of a simple, rapid, selective and economical reverse phase high performance liquid chromatography-diode array detection (HPLC-DAD) method for the simultaneous determination of paritaprevir (PAR), ombitasvir (OMB), dasabuvir(DAS) and ritonavir (RIT) in bulk and pharmaceutical preparations...

Nalini M Nadkarni
On July 3, 2015, Nalini Nadkarni, a world-renowned ecologist who had been studying the biologic processes of ecosystem disturbance and recovery, sustained a catastrophic 50-foot free-fall from the top of the rainforest canopy to the forest floor at her remote field research site. She lost consciousness in shock and sustained life-threatening injuries. Her accompanying students hiked out, radio-called 911, and the Harborview Medical Center (Seattle) Medivac team arrived 4 hours later to rescue her. Her prognosis was extremely grim; her family gathered in anticipation of her death as she underwent four operations during her 10 days in the ICU...

Over the past 20 years, critical care has matured in a myriad of ways resulting in dramatically higher survival rates for our sickest patients. For millions of new survivors comes de novo suffering and disability called "the postintensive care syndrome." Patients with postintensive care syndrome are robbed of their normal cognitive, emotional, and physical capacity and cannot resume their previous life. The ICU Liberation Collaborative is a real-world quality improvement initiative being implemented across 76 ICUs designed to engage strategically the ABCDEF bundle through team- and evidence-based care...

Molecular diagnostics is typically outsourced to well-equipped centralized laboratories, often far from the patient. We developed molecular assays and portable optical imaging designs that permit on-site diagnostics with a cost-effective mobile-phone-based multimodal microscope. We demonstrate that targeted next-generation DNA sequencing reactions and in situ point mutation detection assays in preserved tumour samples can be imaged and analysed using mobile phone microscopy, achieving a new milestone for tele-medicine technologies...

The rhizome of Anemone raddeana Regel, a Traditional Chinese Medicine (TCM) which has a robust history treating rheumatism and neuralgia. The total secondary saponin (TSS) from it has demonstrated antitumor activity. In this study, a rapid and validated LC-MS/MS method was developed to simultaneously determine the active compounds (Hederacolchiside A1 and Eleutheroside K). Analytes were separated on a reverse-phase C18 column with acetonitrile-water (5mmol/L ammonium acetate) as the mobile phase. This assay showed acceptable linearity (r>0...

BACKGROUND: Deuterium oxide is a molecule that has been used for decades in several studies related to human health. Currently, studies on D2O have mobilized a "Race for Patenting" worldwide. Several patents have been registered from biomedical and technological studies of D2O showing the potential of this stable isotope in industry and health care ecosystems. METHODS: Most of the patents relating to applications of the deuterium oxide in human health have been summarized in this review...

In low-resource settings, where qualified health workers (HWs) are scarce and childhood mortality high, rational antimicrobial prescription for childhood illnesses is a challenge. To assess whether smartphones running guidelines, as compared with paper support, improve consultation process and rational use of medicines for children, a pilot cluster-randomized controlled study was conducted in Tanzania. Nine primary health-care facilities (HFs) were randomized into three arms: 1) paper algorithm, 2) electronic algorithm on a smartphone, and 3) control...

Hypaconitine is an active component of Aconitum carmichaelii Debx, a Chinese medicinal herb for the treatment of cardiovascular diseases, but the mechanism underlying its effect remains elusive. In this study, we found that hypaconitine, rather than aconitum alkaloids in A. carmichaelii (e.g. aconitine, mesaconitine and benzoylaconitine), prevented endothelial cells from damage due to oxidized low-density lipoprotein (oxLDL) challenge. Cleaved caspase 3 expression in endothelial cells was up-regulated by oxLDL and markedly attenuated by hypaconitine, suggesting that hypaconitine inhibited the oxLDL-induced cell apoptosis...

BACKGROUND: Certain disadvantages of the standard hematopoietic stem and progenitor cell (HSPC) mobilizing agent G-CSF fuel the quest for alternatives. We herein report results of a Phase I dose escalation trial comparing mobilization with a peptidic CXCR4 antagonist POL6326 (balixafortide) vs. G-CSF. METHODS: Healthy male volunteer donors with a documented average mobilization response to G-CSF received, following ≥6 weeks wash-out, a 1-2 h infusion of 500-2500 µg/kg of balixafortide...

REVIEW
Helena Baptista, Inês Lopes Cardoso
Steinert syndrome, also called myotonic dystrophy type 1, is a genetic disorder with autosomal dominant transmission characterized by myotonia and a multisystemic clinical picture that affects several tissues of the human body. The most common systemic phenotypes are: muscular, cardiac, respiratory, CNS, ocular, gynecological, digestive, orthopedical, as well as cognitive and psychological symptoms (cognitive decline). Muscles involved in voluntary movement are highly affected by myotonia especially distal muscles of upper limbs...

REVIEW
Anthony Faiola, Richard J Holden
People are at risk from noncommunicable diseases (NCD) and poor health habits, with interventions like medications and surgery carrying further risk of adverse effects. This paper addresses ways people are increasingly moving to healthy living medicine (HLM) to mitigate such health threats. HLM-seekers increasingly leverage mobile technologies that enable control of personal health information, collaboration with clinicians/other agents to establish healthy living practices. For example, outcomes from consumer health informatics research includes empowering users to take charge of their health through active participation in decision-making about healthcare delivery...
