PURPOSE: Little is known about the relationship between concentrations in oral fluid (OF) and blood for the widely prescribed hypnotic drug zopiclone. The purpose of this study was to investigate the usefulness of OF zopiclone concentrations to predict blood zopiclone concentrations in order to introduce OF testing as an alternative to more cumbersome blood testing. METHODS: 16 healthy young male volunteers received capsules of either 5 or 10mg zopiclone on two different study days separated by at least one week...

Natural products with immunomodulatory activity are widely used in treatment of many diseases including autoimmune diseases, inflammatory disorders in addition to cancer. They gained a great interest in the last decades as therapeutic agents since they provide inexpensive and less toxic products than the synthetic chemotherapeutic agents. Immunomodulators are the agents that have the ability to boost or suppress the host defense response that can be used as a prophylaxis as well as in combination with other therapeutic modalities...

BACKGROUND: Stenosis is a troublesome complication after wide endoscopic submucosal dissection (ESD). As steroids are known to prevent post-ESD esophageal stenosis, this study aimed to clarify the gastric effects. METHODS: This was a retrospective single-institution study. Between September 2002 and June 2015, 132 patients with a post-ESD mucosal defect exceeding three-fourths of the circumference were identified. Among them, 107 patients who did not undergo additional surgery for non-curative resection were reviewed...

Mathematical modeling has a long history in the field of cancer therapeutics, and there is increasing recognition that it can help uncover the mechanisms that underlie tumor response to treatment. However, making quantitative predictions with such models often requires parameter estimation from data, raising questions of parameter identifiability and estimability. Even in the case of structural (theoretical) identifiability, imperfect data and the resulting practical unidentifiability of model parameters can make it difficult to infer the desired information, and in some cases, to yield biologically correct inferences and predictions...

Conditions of severe hyper-inflammation can lead to uncontrolled activation of macrophages, and the ensuing phagocytosis of live cells. However, relationships between inflammatory stimuli and uncontrolled phagocytosis of live cells by macrophages are poorly understood. To identify mediators of this process, we established phagocytosis assays of live cells by stimulating macrophages with CpG DNA, interferon-γ, and anti-interleukin-10 receptor antibody. In this model, various cell surface receptors were upregulated on macrophages, and phagocytosis of live cells was induced in a Rac1-dependent manner...

Combined estrogen-progestin preparations (CEPs) are associated with thromboembolic (TE) side effects. The aim of this study was to evaluate the incidence of TE using the Japanese Adverse Drug Event Report (JADER) database. Adverse events recorded from April 2004 to November 2014 in the JADER database were obtained from the Pharmaceuticals and Medical Devices Agency (PMDA) website (www.pmda.go.jp). We calculated the reporting odds ratios (RORs) of suspected CEPs, analyzed the time-to-onset profile, and assessed the hazard type using Weibull shape parameter (WSP)...

Chemical stability is a major concern in the development of protein therapeutics due to its impact on both efficacy and safety. Protein "hotspots" are amino acid residues that are subject to various chemical modifications, including deamidation, isomerization, glycosylation, oxidation etc. A more accurate prediction method for potential hotspot residues would allow their elimination or reduction as early as possible in the drug discovery process. In this work, we focus on prediction models for asparagine (Asn) deamidation...

The long non-coding RNA HOX transcript antisense RNA (HOTAIR) plays a key role in the progression of various carcinomas. However, whether or not HOTAIR influences glucose metabolism and the specific underlying mechanism in hepatocellular carcinoma (HCC) cells remain unclear. In the present study, we found markedly increased HOTAIR expression in 84 HCC tissues and demonstrated that HOTAIR overexpression promoted cell proliferation using Cell Counting Kit-8. The effect on glucose metabolism regulated by HOTAIR in HCC cells was determined by detecting lactate and glucose levels: HOTAIR promoted glycolysis by upregulating glucose transporter isoform 1 (GLUT1) and activating mammalian target of rapamycin (mTOR) signaling, whereas knockdown of HOTAIR suppressed this effect...

The blood-brain barrier (BBB) protects the brain from toxic material in the blood, provides nutrients for brain tissues, and screens harmful substances from the brain. The specific brain microvascular endothelial cells (BMVECs), tight junction between endothelial cells, and astrocytes ensure proper function of the central nervous system (CNS). Pathological factors disrupt the integrity of the BBB by destroying the normal function of endothelial cells and decreasing the production of tight junction proteins or the expression of proteins specifically localized on astrocytes...

PURPOSE: Osteosarcoma (OS) is one of the most prevalent primary malignant bone tumors in adolescent. HOTAIR is highly expressed and associated with the epigenetic modifications, especially DNA methylation, in cancer. However, the regulation mechanism between HOTAIR and DNA methylation and the biological effects of them in the pathogenesis of osteosarcoma remains elusive. METHOD: Through RNA-sequencing and computational analysis, followed by a variety of experimental validations, we report a novel interplay between HOTAIR, miR-126, and DNA methylation in OS...

Acetaminophen (APAP, paracetamol) overdose has been the most frequent cause of drug-induced liver failure. APAP-induced liver toxicity can be fatal in many cases even with treatment of the clinically used N-acetylcysteine (NAC), and the need for novel therapeutic agents is apparent. Through evaluating the hepatoprotective effects of the co-occurring substances present in oleanolic acid tablets which have been used in China for decades as an adjuvant therapy for acute and chronic hepatitis, auriculatone was found to protect HL-7702 cells from APAP-induced liver injury comparable to NAC at the concentration of 10μM...

The Achilles tendon has a unique structure-function relationship thanks to its innate hierarchical architecture in combination with the rotational anatomy of the sub-tendons from the triceps surae muscles. Previous research has provided valuable insight in global Achilles tendon mechanics, but limitations with the technique used remain. Furthermore, given the global approach evaluating muscle-tendon junction to insertion, regional differences in tendon mechanical properties might be overlooked. However, recent advancements in the field of ultrasound imaging in combination with speckle tracking have made an intratendinous evaluation possible...

Metabolic disease is a significant problem that causes a range of species-specific comorbidities. Recently, a better understanding of glucose-dependent insulinotropic polypeptide (GIP) biology has led to the suggestion that inhibiting its action may attenuate obesity in several species. In horses, antagonism of GIP may also reduce hyperinsulinemia, which leads to insulin-associated laminitis, a painful comorbidity unique to this species. However, little is known about GIP in horses. The aims of this study were to examine the tissue distribution of equine GIP receptors (eGIPR), to determine whether eGIPR can be blocked using a GIP antagonist not tested previously in horses, and to establish whether there is any association between GIP concentrations and body mass in this species...
