Malaria remains a major public health problem in the Democratic Republic of Congo (DRC) with 14 million cases reported by the WHOMalaria Report in 2014. Asymptomaticmalaria cases are known to be prevalent in endemic areas and are generally untreated,resulting in a significant source of gametocytes that may serve as reservoir of disease transmission. Considering that microscopycertainly underestimates the prevalence of Plasmodium infections within symptomatic carriers and that PCR assays are currentlyrecognized as the most sensitive methods for Plasmodium identification, this study was conducted to weigh the asymptomatic carriage in DRC by a molecular method. Six provinces were randomly selected for blood collection in which 80 to 100 individuals were included in the study. Five hundred and eighty blood sampleswere collected andmolecular diagnosiswas performed. Globally, almost half of the samples collected from asymptomatic individuals (280/580; 48.2%) had Plasmodium infections and the most species identified was P. falciparum alone in combination with P. malariae. The high prevalence reported here should interpellate the bodies involved in malaria control in DR Congo to take into account asymptomatic carriers in actions taken and consider asymptomatic malaria as a major hurdle for malaria elimination.

Abstract Production of SPARC/osteonectin/BM-40 was determined in mouse B16 melanoma clones BL6 and F10 (high metastatic) and F1 (low metastatic). SPARC was produced greater amount in BL6 and F10 than in F1 cells, showing a good agreement with their metastatic potentials. Moreover, SPARC production was not influenced by culture pH, even in the acidic conditions (= pH 5.9). Although tumor tissues show often low pH due to excessive amount of acidic metabolites such as lactate, most studies have been done in neutral pH. High SPARC production in the acidic medium, therefore, is thought to be an important potential for tumor invasive behaviour. [less ▲]

Dietary composition affects body composition; the role of fat and carbohydrates is well documented. Proteins are more satiating than carbohydrates, may produce different effects on glycemia , and are more thermogenic. Indeed the efficiency of cellular conversion of energy to high-energy yielding phosphate bonds from fatty acids is 90%, from carbohydrates 75%, but only 55% for amino acids. High-protein diets produced greater weight loss in some studies of obese humans but not others. Other human studies found that although the high-protein diet did not promote weight loss in excess of control diets, it did preserve lean tissue mass and promoted the loss of fat tissue . Companion animals also suffer from obesity , and a high-protein, energy-restricted diet was successful in reducing the body weight and body fat of overweight dogs and cats , and in conserving lean body mass of dogs . However, there have been few studies of the effects of protein intake on the body composition in normal-weight individuals of any species. The current study aimed to determine the effect of a limited energy intake of a high-protein diet on the body composition and least observed metabolism (LOM)5 of adult neutered cats. [less ▲]

Microbial fermentation in the rumen produces methane (CH4) which is a loss of energy for ruminants and also contributes to global warming. While the respiration chamber is the standard reference for CH4 emissions quantification, daily CH4 production dynamics can be measured only by steps of 30 min and measurements on pasture are impossible. The alternative method using SF6 as tracer gas can be applied for grazing animals but provides average CH4 production values over at least several hours, making it impossible to measure short term dynamics of rumen CH4 production with changing animal behavior along the day. Newly developed methods using CO2 as internal tracer gas extrapolate CH4 emissions from few short measurements. However, both CO2 and CH4 emissions fluctuate during the day depending on the behavior and the post-feeding times questioning the validity of this method. Therefore, an innovative device was developed to monitor at a high rate CH4 and CO2 emission dynamics in order to investigate the link between CH4 dynamics and the animal behavior on pasture. Preliminary results showed the ability of the device to record differences in CH4:CO2 ratios and eructation frequencies according to the individual and the behavior. Results from complementary experiments in barn with animals fed contrasting diets regarding CH4 production (with and without linseed) and on pasture with different forage allowance will be presented in order to highlight how post-feeding time and grazing behavior impact CO2 and CH4 emission dynamics along the day.

Systemic Sclerosis (SSc) is a chronic multisystemic connective tissue disease characterized by progressive fibrosis affecting skin and internal organs. Despite serious efforts to unveil the pathogenic mechanisms of SSc, they are still unclear. High levels of Reactive Oxygen Species (ROS) in affected patients have been shown, and ROS are suggested to play a role in fibrosis pathogenesis. In this study we evaluate ROS levels in non-fibrotic and fibrotic skin of patients with SSc and we compare them with those obtained from healthy controls. Patients and Methods We enrolled 9 SSc patients fulfilling the EULAR/ACR classification criteria and 7 healthy controls. Patients included were 4 men and 5 women with mean age of 46 ±10 yrs. Controls were matched by sex and age. All patients were affected by diffuse cutaneous form of SSc and the ANA pattern anti-Scl70. Mean disease duration was 7.5±5 yrs. Skin involvement was evaluated by modified Rodnan Skin Score (mRSS). Skin samples (4 mm punch biopsy) were taken from fibrotic skin and non-fibrotic skin of patients and from healthy controls as well. To detect ROS, specimens were analyzed immediately after sampling by electron paramagnetic resonance spectroscopy. Blood samples have been drawn from all patients and controls to assess oxidative stress biomarkers. Results ROS levels (expressed as median and range, unit of measurement was nmol/l/min/mg of dry weight) were 24.7 (10.9– 47.0) in fibrotic skin, 18.7 (7.3–34.0) in non-fibrotic skin and 7.7 (3.5–13.6) in healthy controls skin. ROS levels in Fibrotic and Non-fibrotic skin of SSc patients were significantly higher than in Healthy Controls (p=0.002 and p=0.009, respectively). ROS levels in fibrotic skin were raised in comparison to non-fibrotic skin, when samples related to each patient were compared (p=0.01). ROS levels in fibrotic skin were correlated with forced vital capacity (r= -0.75, p=0.02) and erythrocyte sedimentation rate (r=0.70, p=0.04). All other clinical and lab parameters showed no significant correlation. When compared to controls, blood from SSc patients showed lower ascorbate (vitamin C) levels (8 [3.8-9.8] vs. 10.5 [9-19.1] mg/L, p=0.004) and higher lipid peroxides (873.5 [342-1973] vs. 422 [105-576] μmol/L, p=0.004). Conclusion Our results indicate the presence of high oxidative stress both in non-fibrotic skin and fibrotic skin of SSc patients, but with higher tendency in the latter. Raised ROS levels in non-fibrotic skin of SSc patients might be a hint of early involvement in skin fibrogenesis. However, a longitudinal prospective study is necessary for such proof. [less ▲]

We show results from a positive degree-day (PDD) model of Greenland ice sheet (GrIS) surface mass balance (SMB), 1870–2012, forced with reanalysis data. The model includes an improved daily temperature parameterization as compared with a previous version and is run at 1 km rather than 5 km resolution. The improvements lead overall to higher SMB with the same forcing data. We also compare our model with results from two regional climate models (RCMs). While there is good qualitative agreement between our PDD model and the RCMs, it usually results in lower precipitation and lower runoff but approximately equivalent SMB: mean 1979–2012 SMB (± standard deviation), in Gt a−1, is 382 ± 78 in the PDD model, compared with 379 ± 101 and 425 ± 90 for the RCMs. Comparison with in situ SMB observations suggests that the RCMs may be more accurate than PDD at local level, in some areas, although the latter generally compares well. Dividing the GrIS into seven drainage basins we show that SMB has decreased sharply in all regions since 2000. Finally we show correlation between runoff close to two calving glaciers and either calving front retreat or calving flux, this being most noticeable from the mid-1990s. [less ▲]

The vibrational spectra induced by electron beam from octadecanethiol monolayers adsorbed on gold are reported as a contribution to study in detail the structure of the layers, through an analysis of the interaction mechanisms between the electrons and these organic ultrathin films. To show the different spatial distribution of scattered electrons from dipole and impact interactions with the monolayer, angular distributions of elastic and inelastic scattered electrons were measured for various primary energies. The absolute electron scattering loss probabilities from both dipole and impact interactions were estimated for different vibrational modes. The study of these different mechanisms was first hampered by the poor order of the layers adsorbed on evaporated gold. It became therefore highly desirable to perform the experiments on a single-crystal substrate. Using Au(111) and Au(100) single crystals as substrates, it was possible to separate the spectral response from impact and dipole interacting electrons. A negative ion resonant behavior has been observed in the energy dependence of the electron scattering differential cross sections [less ▲]
