Human gliomas are a heterogeneous group of primary malignant brain tumors, which most commonly occur in the central nervous system of children and adults. Previous studies have suggested a prognostic role of matrix metalloproteinase 9 (MMP9) in glioma, however, the frequency and significance of the protein expression of MMP9 in glioma remain to be fully elucidated. In the present study, the expression of MMP9 was detected by reverse transcription-quantitative polymerase chain reaction (qPCR), western blotting and immunohistochemical staining...

OBJECTIVES: A robust literature documents generational trends in drug use. We examined the implications of changing national drug use patterns on drug injection histories of diverse people who inject drugs (PWID). METHODS: Drug use histories were collected from 776 active PWID in 2011-13. Using descriptive statistics, we examine drug use initiation by year and birth cohort (BC) differences in drug first injected. A multivariate linear regression model of time to injection initiation ([TTII] (year of first injection minus year of first illicit drug use) was developed to explore BC differences...

Next-generation sequencing (NGS) facilitates the rapid and high-throughput generation of human mitochondrial genome (mitogenome) data to build population and reference databases for forensic comparisons. To this end, long-range amplification provides an effective method of target enrichment that is amenable to library preparation assays employing DNA fragmentation. This study compared the Nextera XT DNA Library Preparation Kit (Illumina, San Diego, CA) and the KAPA HyperPlus Library Preparation Kit (Kapa Biosystems, Wilmington, MA) for enzymatic fragmentation and indexing of ∼8500bp mitogenome amplicons for Illumina sequencing...

BACKGROUND: Use of high-risk medications in the elderly (HRME) and drug-disease (Rx-DIS) interactions in the elderly, as defined by the Healthcare Effectiveness Data and Information Set (HEDIS) Measures, are significantly associated with mortality, hospital admission, and need for emergency care. No published studies to date evaluate interventions to reduce the use of HEDIS-defined HRME, although many studies have postulated a beneficial effect of such interventions. OBJECTIVE: To evaluate the effect of pharmacist interventions on use of HRME and Rx-DIS interactions in the outpatient elderly population...

BACKGROUND: In 2012, hydrocodone combination products (HCPs) were the most prescribed medications in the United States. Under the Controlled Substance Act of 1970, hydrocodone alone was classified as a Schedule II drug, while HCPs were classified as Schedule III, indicating a lower risk for abuse and misuse. However, according to a Drug Enforcement Agency analysis, the addition of nonopioids has not been shown to diminish abuse potential of hydrocodone. In response to concerns for drug abuse and overdose, the Drug Enforcement Agency rescheduled HCPs to Schedule II in October 2014, with the intent of limiting overprescribing and increasing awareness of their abuse potential...

Adenovirus (AdV) morphogenesis is a complex process, many aspects of which remain unclear. In particular, it is not settled where in the nucleus assembly and packaging occur, and whether these processes occur in a sequential or a concerted manner. Here we use immunofluorescence and immunoelectron microscopy (immunoEM) to trace packaging factors and structural proteins at late times post infection by either wildtype virus or a delayed packaging mutant. We show that representatives of all assembly factors are present in the previously recognized peripheral replicative zone, which therefore is the AdV assembly factory...

This study explores experiences of intensive community treatment, illness, and change among patients with severe anorexia nervosa (sAN), particularly seeking to understand the processes involved in change and inability to change. A qualitative design with purposive semi-stratified sampling, using semi-structured interviews and interpretive phenomenological analysis, investigated in detail the experiences of five participants. Participants all had sAN at the start of treatment and represented a spectrum of outcomes from deterioration to full recovery...

Adrenocortical carcinoma (ACC) is a rare and malignant tumor. The main treatment is primary surgical resection with or without mitotane therapy. The role of radiation therapy is still controversial. We aim to investigate the survival efficacy of radiotherapy in a large population-based cohort.We queried the Surveillance, Epidemiology, and End Results (SEER) database (1973-2013) to identify cases with ACC. Traditional multivariate Cox regression and propensity score analysis were used to evaluate the effect of radiotherapy on cancer survival...

BACKGROUND: Lipocalin-2 (Lcn2) is a multifunctional innate immune protein that exhibits antimicrobial activity by the sequestration of bacterial siderophores, regulates iron homeostasis, and augments cellular tolerance to oxidative stress. Studies in the murine model of colitis have demonstrated that Lcn2 deficiency exacerbates colitogenesis; however, the therapeutic potential of Lcn2 supplementation has yet to be elucidated. In light of its potential mucoprotective functions, we, herein, investigated whether expression of Lcn2 in the probiotic bacterium can be exploited to alleviate experimental colitis...

We investigate the influence of pH on the rheological and structural properties of hydrogels formed by hydrophobic association of the sticky ends of the triblock terpolymer poly(methyl methacrylate)-b-poly(2-(diethylamino)ethyl methacrylate-co-methacrylic acid)-b-poly(methyl methacrylate) (PMMA-b-P(DEA-co-MAA)-b-PMMA). The middle block is a weak polyampholyte having a pH dependent charge density and sign, which enables tuning of the rheological and structural properties by pH variation. Small-angle neutron scattering (SANS) studies of solutions in D2O at 0...

An accurate grasp of the mechanical properties, especially Young's moduli, of one dimensional nanomaterials plays a crucial role in the design and safe service of flexible electronic devices and implanted biomedical sensors. Nanobridge tests are widely used in the characterization of the mechanical properties of nanowires. In these tests, an atomic force microscope (AFM), functioning as a test machine, exerts a force to bend a nanowire suspended across a trench or a hole with the two ends fixed on a template or substrate...

We developed a dynamic multimedia fate and transport model (nanoFate) to predict the time-dependent accumulation of metallic engineered nanomaterials (ENMs) across environmental media. nanoFate considers a wider range of processes and environmental sub-compartments than most previous models and considers ENM releases to compartments (e.g. urban, agriculture) in a manner that reflects their different patterns of use and disposal. As an example, we simulated ten years of release of nano CeO2, CuO, TiO2, and ZnO in the San Francisco Bay area...
