REVIEW
Seung Hwan Lee, Jong Hwan Sung
In the drug development process, the accurate prediction of drug efficacy and toxicity is important in order to reduce the cost, labor, and effort involved. For this purpose, conventional 2D cell culture models are used in the early phase of drug development. However, the differences between the in vitro and the in vivo systems have caused the failure of drugs in the later phase of the drug-development process. Therefore, there is a need for a novel in vitro model system that can provide accurate information for evaluating the drug efficacy and toxicity through a closer recapitulation of the in vivo system...

Mary E Lohman, Peter A Lio
The development of effective systemic treatments has revolutionized the treatment of inflammatory skin diseases. The availability of safe new treatments and the understanding of psoriasis as a systemic disease with comorbidities and effects on quality of life have driven the current aggressive treatment paradigm of psoriasis. Historically the morbidity of atopic dermatitis (AD) has been dismissed, given the perception of AD as "just" a rash. Differences in the guidelines for psoriasis and AD management may suggest variations in the current conceptualization of disease severity and effects on quality of life...

REVIEW
Ricardo Henrique Belmiro, Alline Artigiani Lima Tribst, Marcelo Cristianini
High pressure homogenization (HPH) is an emerging process in which a fluid product is pumped by pressure intensifiers forcing it to flows through a narrow gap, usually measured in the order of micrometers. Gums are polysaccharides from vegetal, animal or microbial origin, widely employed in food and chemical industries as thickeners, stabilizers, gelling agents and emulsifiers. Choosing a specific gum will depend on its application and purpose, as each form of gum has particular values for viscosity, intrinsic viscosity, stability, emulsifying and gelling properties, being these parameters determined by its structure...

Developing a thorough understanding of experimental methods of hepatic differentiation in hepatic progenitor cells (HPCs) should expand the knowledge of hepatocyte induction in vitro and may help to develop cell transplantation therapies for the clinical usage of HPCs in liver diseases. A previous induction method effectively induced differentiation and metabolic abilities in HPCs. Periodic acid‑Schiff (PAS) staining is used to identify glycogen synthesis and hepatocyte function; however, this method failed to detect induced hepatocytes...

Jun-Feng Li, Su-Jun Zheng, Li-Li Wang, Shuang Liu, Feng Ren, Yu Chen, Li Bai, Mei Liu, Zhong-Ping Duan
Our previous study found that glucosylceramide, a type of sphingolipids, was associated with liver inflammation and fibrosis. Glucosylceramide is generated by glucosylceramide synthase (GCS), which is encoded by the UDP‑glucose ceramide glucosyltransferase (UGCG) gene. GCS is a key enzyme to regulate the physiological activity of cells. However, the role of GCS in hepatic cells remains unclear. The aim of the present study was to explore the mechanism of GCS in the proliferation and apoptosis of liver cells...

Ling Gao, Yingjie Hu, Jing Li
The authors previously reported that pigment epithelium‑derived factor (PEDF) protects the diabetic kidney from fibrosis via its anti‑oxidative effects. However, the underlying molecular mechanism has never been revealed. The present study aimed to investigate how PEDF protects mesangial cells from diabetes induced damage. Human mesangial cells were exposed to a diabetic environment [30 mmol/l glucose and 200 mg advanced glycation end products (AGEs)] in the absence or presence of PEDF (200 mg/l). The superoxide and peroxynitrite productions were measured by fluorescent assay...

Gastric cancer is one of the most common cancers and the second leading cause of cancer‑associated mortality worldwide. Recurrence, metastasis and resistance to drug treatment are the main barrier to survival of patients with advanced stage gastric cancer. Further study of the molecular mechanisms involved will improve the therapeutic options for gastric cancer. In a previous study, c‑Maf was discovered as an oncogene transduced in the avian AS42 retrovirus, and was found to be overexpressed in multiple myeloma and angioimmunoblastic T‑cell lymphoma...

The methodology of direct C(sp(2))-H functionalization has for the first time been applied as an efficient and advanced approach to carry out C-H/C-H coupling of 2H-imidazole 1-oxides and pyrroles. The atom-economical method used does not require either any auxiliary group in the starting substrates, or catalysis by transition metals. As a result, a number of novel 1H-pyrrol-2-yl-2H-imidazoles, that are particularly of interest in the design of bioactive molecules, have been prepared under mild conditions and in good to excellent yields...

We propose the use of folate-receptor-targeted, near-infrared-sensitive polydopamine nanoparticles (NPs) for chemo-photothermal cancer therapy as an enhanced type of drug-delivery system which can be synthesized by in situ polymerization and conjugation with folic acid. The NPs consist of a Fe3O4/Au core, coated polydopamine, conjugated folic acid, and loaded anti-cancer drug (doxorubicin). The proposed multifunctional NPs show many advantages for therapeutic applications such as good biocompatibility and easy bioconjugation...

Bing Han, Louis M Weiss
Microsporidia are obligate intracellular pathogens related to Fungi. These organisms have a unique invasion organelle, the polar tube, which upon appropriate environmental stimulation rapidly discharges out of the spore, pierces a host cell's membrane, and serves as a conduit for sporoplasm passage into the host cell. Phylogenetic analysis suggests that microsporidia are related to the Fungi, being either a basal branch or sister group. Despite the description of microsporidia over 150 years ago, we still lack an understanding of the mechanism of invasion, including the role of various polar tube proteins, spore wall proteins, and host cell proteins in the formation and function of the invasion synapse...

With unique physicochemical properties, gold nanoparticles (Au NPs) have demonstrated their potential as drug carriers or therapeutic agents. Effective guidance of Au NPs into specific intracellular destinations becomes increasingly important as we strive to further improve the efficiency of drug delivery and modulate controllable cellular responses. In this review, we summarized recent advances in designing Au NPs with the capabilities of cellular penetration and internalization, endosomal escape, intracellular trafficking and subcellular localization via various approaches including physical injection, tuning the physiochemical parameters of Au NPs, and surface modification with targeting ligands...

BACKGROUND: The rise in pharmaceutical expenditures in recent years has increased health care payer interest in ensuring good value for the money. Indication-based pricing (IBP) sets separate, indication-specific prices paid to the manufacturer according to the expected efficacy of a drug in each of its indications. IBP allows payers to consistently pay for value across indications. While promising, a limitation of IBP as originally conceived is that efficacy estimates are typically based on clinical trial data, which may differ from real-world effectiveness...

Will Guest, Dipanka Sarma, Thomas Marotta
Thromboembolic stroke from migration of thrombus formed in non-giant intracranial aneurysms is a recognized but rare event. We describe a case of partial thrombosis of a 7 mm anterior communicating artery aneurysm, which embolized to the right callosomarginal artery in the brief time interval between two sequential diagnostic angiograms performed as part of elective endovascular coiling, and before any instrumentation had been advanced into the intracranial circulation. To our knowledge, this is the first reported case of aneurysmal thrombus embolization observed angiographically in near real time...

Nanostructured electrodes are at the forefront of advanced materials research, and have been studied extensively in the context of their potential applications in energy storage and conversion. Here, we report on the properties of core-shell (gold-polypyrrole) hybrid nanowires and their suitability as electrodes in electrochemical capacitors and as electrocatalysts. In general, the specific capacitance of electrochemical capacitors can be increased by faradaic reactions, but their charge transfer resistance impedes charge transport, decreasing the capacitance with increasing charge/discharge rate...

Active learning strategies have proved effective in changing behaviours and encouraging continuing professional development (CPD) in nursing. Narrative pedagogy in particular has demonstrated its usefulness in this regard. This article describes narrative pedagogy through the lens of learning activities conducted in the classroom and in the course of practicum and CPD experiences. It also examines the challenges associated with implementing such activities and how to meet them. This includes not determining the content of activities completely in advance, specifying that the content to be discussed is not entirely known, that additional research could be required and that different options are to be explored, allowing students to express themselves freely, and tolerating moments of silence...
