Multistrain diseases are diseases that consist of several strains, or serotypes. The serotypes may interact by antibody-dependent enhancement (ADE), in which infection with a single serotype is asymptomatic, but infection with a second serotype leads to serious illness accompanied by greater infectivity. It has been observed from serotype data of dengue hemorrhagic fever that outbreaks of the f...

This paper examines the effects of single-strain vaccine campaigns on the dynamics of an epidemic multistrain model with antibody-dependent enhancement (ADE). ADE is a disease spreading process causing individuals with their secondary infection to be more infectious than during their first infection by a different strain. We follow the two-strain ADE model described in Cummings et al. [D.A.T. C...

The incision of DNA at apurinic/apyrimidinic sites (AP-sites) by chloro-6-methoxy-2 [(adenyl-9)-11)-4,8 diazadecyl]amino-9 acridine (Ade-Z-Acr), a 9-aminoacridine linked to an adenine, at nanomolar concentrations is described. Moreover, this drug, Ade-Z-Acr, is one of the most efficient drugs which cleaves DNA at AP-sites. The high activity is the result of the composition of the drug, since th...

The RNA-binding protein Roquin is required to prevent autoimmunity. Roquin controls T-helper cell activation and differentiation by limiting the induced expression of costimulatory receptors such as tumor necrosis factor receptor superfamily 4 (Tnfrs4 or Ox40). A constitutive decay element (CDE) with a characteristic triloop hairpin was previously shown to be recognized by Roquin. Here we use S...

Sub-neutralizing concentrations of antibody to dengue virus (DENV) enhance DENV infection of Fc gamma receptor-expressing cells. This phenomenon, referred to as antibody-dependent enhancement (ADE), has been hypothesized to be responsible for the severe form of DENV infection, including dengue haemorrhagic fever and dengue shock syndrome. To analyse further the mechanisms of ADE in vitro, this ...

BACKGROUND Although numerous studies have used wastewater as substitutes to cultivate microalgae, most of them obtained weaker algal viability than standard media. Some studies demonstrated a promotion of phytohormones on algal growth in standard media. For exploiting a strategy to improve algal biomass accumulation in effluent from anaerobic digestion of kitchen waste (ADE-KW), the agricultura...

Adverse drug events (ADE) may lead to hospital admission, and in some cases admission to an ICU is mandatory. We conducted a systematic review dealing with the incidence of ADE requiring ICU admission in adult patients, the reference population being all ICU admissions. Medline, Embase and Web of Science databases were screened from January 1982 to July 2014, using appropriate key words. Only o...

By incubating explants from Actinidia arguta seedlings on a nutrient medium supplemented with 20 to 30 micromolar N(6)-(Delta(2)-isopentenyl)adenine (i(6)Ade) and then measuring zeatin (io(6)Ade) accumulation in tissues, the distribution of i(6)Ade hydroxylase activities in whole plants could be determined. Based on analyses with three entire plants, it is estimated that, as an organ system, ro...

BACKGROUND Direct patient reporting of adverse drug events (ADEs) is relevant for the evaluation of drug safety. To collect such data in clinical trials and postmarketing studies, a valid questionnaire is needed that can measure all possible ADEs experienced by patients. OBJECTIVE Our aim was to develop and test a generic questionnaire to identify ADEs and quantify their nature and causality ...
