Quantitative assessment of the antiviral potencies of 21 shRNA vectors targeting conserved, including structured, hepatitis B virus sites

Background & Aims: RNA interference (RNAi) may offer new treatment options for chronic hepatitis B. Replicating via an RNA intermediate, hepatitis B virus (HBV) is known to be principally vulnerable to RNAi. However, beyond delivery, the relevant issues of potential off-target effects, target site conservation in circulating HBV strains, and efficacy of RNAi itself have not systematically been

A democratic critique of precarity

The term ‘precarity’ has become increasingly popular as a way to capture the material and psychological vulnerability resulting from neoliberal economic reforms. This article demonstrates that such precarity is incompatible with democracy. More specifically, it makes two arguments. First, and inspired by Montesquieu’s analysis of ‘the principles’, or public commitments behind different forms of go

The first record of conopid flies (Diptera: Conopidae) and eulophid wasps (Hymenoptera: Eulophidae) as parasitoids and hyperparasitoids associated with carpenter bees (Apidae: Xylocopinae) in Argentina

This is the first record for the parasitoid association between eulophids and conopids in the carpenter bee Xylocopa augusti Lepeletier. Biological features of Physocephala Schiner are mentioned. A diagnosis for Pediobius williamsoni (Girault) is given and morphological characters are illustrated.

Methods for the preparation of chlorophyllide a: an intermediate of the chlorophyll biosynthetic pathway

Chlorophyllide a is a metabolite late in the biosynthesis of chlorophylls and bacteriochlorophylls. Isolation procedures for chlorophyllide a from Rhodobacter capsulatus CB1200 and barley (Hordeum vulgare L.) are described and compared. R. capsulatus CB1200 is a double mutant in the bacteriochlorophyllide a biosynthetic pathway, and chlorophyllide a is excreted by the cells when grown in Tween 80-

Dissolution driven crack branching in polycarbonate

Stress corrosion, in the form of chemically assisted crack growth, in polycarbonate is examined with focus on crack branching characteristics. Cracks with finite width are observed; this is to be expected for dissolution driven cracking. The cracks branched repeatedly and crack widths before and after branching are measured. Both symmetric and asymmetric branching is found. The dissolution rate is

A serious bleeding complication with injury of the corona mortis with the TVT-Secur procedure

We report a serious complication following a TVT-Secur procedure due to injury of the corona mortis requiring a surgical intervention for removal of 1 l of clotted blood from the space of Retzius. The corona mortis is an anomaly of the vessel combining the obturator and epigastric arteries passing over the superior pubic ramus, well known to hernia and orthopedic surgeons but probably less well kn

Momentary Contentment: A Modern Version of an Old Survival Culture

This is a classic grounded theory based in longitudinal data from everyday life in an environment in Northern Norway characterized by long distances, a harsh climate and people living close to nature and each other. The place has a history of poverty and isolation. Yet, old survival strategies prevail despite modernisation. The theory reveals a culture of momentary contentment with three dimension

Making marketswith active labor market policies: the influence of political parties, welfare state regimes, and economic change on spending on different types of policies

Active labor market policies consist of a diverse set of policy tools with which to address joblessness and the degree to which governments invest in various policies as a response to rising unemployment varies widely. Fleshing out the determinants by policy type holds the promise of illuminating more clearly contestation over activation. To this end, this study analyzes the role of partisanship a

Sales Maximization or Profit Maximization? How State Shareholders Discipline their CEOs in China*

This study examines the determinants of Chief Executive Officer (CEO) turnover in Chinese state-owned firms. Based on a sample of 1 555 turnover cases among listed firms in China during the period 19992003, we obtain three main results. First, CEO turnover is negatively related to the sales performance but not the profitability of the core business. Second, the negative relationship between CEO tu

Evidence for SMAD3 as a modifier of breast cancer risk in BRCA2 mutation carriers

Introduction: Current attempts to identify genetic modifiers of BRCA1 and BRCA2 associated risk have focused on a candidate gene approach, based on knowledge of gene functions, or the development of large genome-wide association studies. In this study, we evaluated 24 SNPs tagged to 14 candidate genes derived through a novel approach that analysed gene expression differences to prioritise candidat

Understanding and influencing teaching and learning cultures at university - A network approach

Academic cultures might be perceived as conservative, at least in terms of development of teaching and learning. Through a lens of network theory this conceptual article analyses the pattern of pathways in which culture is constructed through negotiation of meaning. The perspective contributes to an understanding of culture construction and maintenance with a potential to aid academic developers a

Expression of cyclin d1 and its association with disease characteristics in bladder cancer.

Aim: Invasive urothelial carcinoma of the bladder (UCB) is characterized by alterations in cell-cycle regulatory pathways. Defects in the expression of cyclin D1, a key cell-cycle regulator, have been implicated in progression of various types of cancer. In the present study, we investigated whether cyclin D1 expression is associated with clinicopathological parameters and whether it has any poten

The implementation of elder-care in France and Sweden: a macro and micro perspective

This paper presents results from a comparative project on the implementation of elder-care in France and Sweden. The transition to requiring care is understood as a process, and elder-care is seen as a part of a more general organisation of social care that reflects different welfare traditions. An overview of elder-care on the institutional level in the two countries is supplemented by case studi

Work-related airway symptoms, nasal reactivity and health-related quality of life in female hairdressers: a follow-up study during exposure.

OBJECTIVES: Hairdressers often complain of work-related rhinitis (WR). They are infrequently sensitized to persulphates. The cause and mechanism of the symptoms and the effects on their health-related quality of life (HRQoL) remains unclear. The objectives were to follow female hairdressers with WR mainly from bleaching powder regarding nasal reactivity to persulphate and to evaluate symptoms, HRQ

Tarski’s one and only concept of truth

In a recent article, David (Tarski’s convention T and the concept of truth, pp. 133–156, 2008) distinguishes between two interpretations of Tarski’s work on truth. The standard interpretation has it that Tarski gave us a definition of truth in-L within the meta-language; the non-standard interpretation, that Tarski did not give us a definition of true sentence in L, but rather a definition of trut

From millet to tomatoes: incremental intensification with high-value crops in contemporary Meru, Tanzania

In Meru, Tanzania, changing land/labour ratios have, for over a century, been the main driving force in a farm intensification process. The construction and expansion of irrigation systems, increased use of farm inputs and transfer from low- to high-value agricultural crops have enabled smallholders to improve their land productivity. Technological change has been accompanied by institutional chan

Common genetic variation near the connexin-43 gene is associated with resting heart rate in African Americans: A genome-wide association study of 13,372 participants

BACKGROUND Genome-wide association studies have identified several genetic loci associated with variation in resting heart rate in European and Asian populations. No study has evaluated genetic variants associated with heart rate in African Americans. OBJECTIVE To identify novel genetic variants associated with resting heart rate in African Americans. METHODS Ten cohort studies participating in th
