Hydroxyurea is an anticancerous product, used recently in the treatment of HIV-1 infection thanks to its inhibitory action in viral replication, potentialization of the nucleosides activity (particularly ddI or didanosine) and its cytostatic properties on CD4 and CD8 lymphocytes. Many studies showed its efficiency, as further drug, in initial regimen of a tritherapy (containing ddI) and salvage therapy. The dosage of 500 mg bid seems tolerated well by adults, and 20 mg/kg by children. Long-term tolerance remains unknown. With ddI, it could be proposed in developing countries. [less ▲]

Several bacterial indicators are used to evaluate the hygiene of the meat slaughtering process. The objectives of this study were to assess the Belgian baseline of hygienic indicators and the relationship between the indicators and zoonotic agents, in order to establish hygiene indicator criteria for carcasses and meat of beef, pork and poultry. The study used the results from the official Belgian surveillance plan from 2000 to 2003, which included the monitoring of counts for E. coli (ECC), Enterobacteriaceae (EC), aerobic colonies (ACC) and Pseudomonas. The sampling method was the wet and dry swabbing technique for beef and pork carcasses, and neck skin excision for chicken and layer carcasses. The 75th and 95th percentiles of ECC were –0.20 and 0.95 log cfu/cm2 for beef carcasses, 1.20 and 2.32 log cfu/cm2 for pork carcasses, and 4.05 and 5.24 log cfu/g for chicken carcasses. The aerobic colony counts were between 2.1 and 4.5 log cfu/cm2 or /g higher than those of ECC for cattle, pork and poultry. For beef and pork carcasses, a significant correlation between ECC, EC and ACC was shown between each parameter. ECC (for pork and beef samples), and EC (in pork carcasses) were detected at significantly higher levels in samples contaminated with Salmonella. In poultry samples, ECC were in general higher for samples containing Salmonella or Campylobacter. This study showed that E. coli may be considered as a good indicator for enteric zoonotic agents such as Salmonella for beef, pork and poultry, and Campylobacter in poultry meat samples. [less ▲]

Coatings are designed to protect concrete against environmental aggression. Water is one of the aggressive parameters able to deteriorate the concrete structure. The objectives of this paper are to present the effects of water (i) during application of coating on the concrete substrate and (ii) pull-off test. Semi-permanent moisty state produced by absorption from the uncoated face, total immersion or diffusion of water from the back face of the substrate are analysed. Water vapour diffusion and influence of hydrophobic treatment are also investigated. A classification based on increasing influence of the tests and application conditions on adhesion is proposed and clearly points out the negative effect of capillary action from the uncoated face.

This paper studies the specific hygrothermal behavior of Lime-Hemp concretes through analysis of non-linear coupled heat and moisture transfer using a research model. Three compositions were studied, varying the type of binder. First Moisture Buffer Value determination tests are lead experimentally using the NORDTEST protocol. These dynamic experiments, which reveal the moisture storage and exchange capacity together with latent heat effects, are then modeled using a set of partial differential equations. The reduction of humidity buffering capacity induced by hydraulic binder incorporation is properly evaluated and the hygrothermal parameters can be assessed by inverse modeling. [less ▲]

Hygroscopic building materials can affect the indoor air by exchanging moisture with it and buffering the ambient humidity variations. The Nordtest protocol and the concomitant Moisture Buffer Value (MBV) parameter definition has been one of the first attempt to characterize this moisture regulation performance. This paper present an attempt to confront this well-established experimental protocol with a mathematical model implemented in the Comsol multiphysics solver. The power of the simulation will be showed with a good correlation between the modelling and the experimental phase for the MBV determination of a lime-hemp concrete bloc. [less ▲]

Most reports published in the field of forensic entomology studies are focused on Diptera pattern colonization and are neglecting Hymenoptera succession. Hymenoptera are part of the entomofaunal colonization of a dead body as parasitoids of fly pupae. However, one should consider Hymenoptera parasitoids in a forensic entomology context to evaluate the time of death. Blowflies parasitoids may indeed be of particular importance as their time of attack is often restricted to a small, well-defined window of developmental time of the insect host. Because these parasitoids also interfere with developmental times of colonizing Diptera, a better understanding of their ecology is needed. [less ▲]

Reverse genetics can be used in the bovine leukemia virus (BLV) system to characterize mechanisms of viral persistence and pathogenesis. The question addressed here pertains to the role of glycans bound to the BLV envelope glycoprotein (SU). A commonly accepted hypothesis is that addition of carbohydrates to the SU protein potentially creates a structure called « glycan shield » that confers resistance to the virus against the host immune response. On the other hand, glycosylation can also modulate attachment of the virus to the cell membrane. To unravel the role of SU glycosylation, three complementary strategies were developed: pharmacological inhibition of different glycosylation pathways, interference with glycan attachment and site-directed mutagenesis of N-glycosylation sites in an infectious BLV provirus. The different approaches show that glycosylation is required for cell fusion, as expected. Simultaneous mutation of all 8 potential N-glycosylation sites destroys infectivity. Surprisingly, mutation of the asparagine residue at position 230 creates a virus having an increased capacity to form syncytia in vitro. Compared to wild-type BLV, mutant N230 also replicates at accelerated rates in vivo. Collectively, this data thus illustrates an example of a N-glycosylation site that restricts viral replication, contrasting with the hypothesis supported by glycan shield model. [less ▲]

We performed high-dispersion near-infrared spectroscopic observations of comet C/2010 G2 (Hill) at 2.5 AU from the Sun using NIRSPEC (R ~ 2.5x10^4) at the Keck II telescope on UT 2012 Jan 9 and 10. The comet had been in outburst. Over the two nights of our observations, prominent emission lines of CH4 and C2H6 along with weaker emission lines of H2O, HCN, CH3OH and CO were detected. The gas production rate of CO was comparable to that of H2O. The mixing ratios of CO, HCN, CH4, C2H6, and CH3OH with respect to H2O are higher than those for normal comets by a factor of five or more. Hyper-volatile species such as CO and CH4 were enriched in the coma of comet Hill suggesting that the sublimation of these hyper-volatiles could sustain the outburst of the comet. Based on a comparison with optical observations, some fraction of water in the inner coma existed as icy grains. Those icy ice grains were likely ejected from nucleus by the sublimation of hyper-volatiles. [less ▲]

Scintimammography performed with Tc-99m sestamibi in a 63-year-old woman with a history of mitral valve replacement and pulmonary hypertension demonstrated that the frequently observed sternal hyperactivity on anterior views could arise from the myocardium. Caution therefore should be taken before the diagnosing of any hyperactivity in the lower sternal region as a neoplastic involvement. [less ▲]
