The commercial potential of passion fruit is expanding as demand for both fresh fruit and processed juice is increasing in Burundi. Due to the current situation with an unstable market of traditional crops for export, farmers in Matongo have embraced passion fruit as a new source of household income. As the crop generates substantial revenues for farmers, wholesalers and processors, it is important to sustain this sector. The purpose of this research was to compare four variants of diffusionist arguments (age, sex, household size and level of education) and their expression into adoption. Comparative descriptive statistical analysis between adopters and non-adopters to test the essential factors, and participatory survey methods for gathering information were used. Our results showed a highly significant difference between the category of adopters and non-adopters at p < 0.01. However, no significant difference was found between adopters and non-adopters within level of education. Data on the level of education demonstrated that those with little or no education adopted more passion fruit [illiterates (48.9%) and primary level (45.9%)] than these with secondary level (5.2%). The heads of household adopters and non-adopters are mainly men at a rate of 83.7 and 88.3 %, and household size was not a discriminating factor. The factors that promote the adoption of passion fruit are high yield and continuous production, high market demand and permanent source of revenue. Defining only a few variables to analyse the adoption trend could mislead our findings. A participatory approach seems most appropriate for understanding adoption and non-adoption of innovation.

Background: Der p 3 a trypsin-like protease is a Dermatophagoides pteronyssinus allergen which is synthesized in the mite under a zymogen form. The enzymatic activity of this allergen has been shown to enhance the inflammatory process of allergy. To date, there are a few studies that described the allergenicity and the IgE reactivity of the group 3 allergens, the allergenic properties of recombinant Der p 3 was also not characterized. Methods: The autolysis of rDer p 3 and rDer p 3 S196A were analyzed by means of SDS-PAGE and enzymatic activity and their allergenicities by means of assays for IgE binding, IgE binding inhibition and basophiles mediator-release. Results: 100% of the sera from allergic patients showed IgE reactivity to natural Der p 3 and recombinant form. However, the IgE binding to the Der p 3 was less 4 times than rDer p 1. The IgE binding to rDer p 3 S196A was higher than rDer p 3. These variations can be linked with the phenomen of autolysis and instability of Der p 3 during the ELISA test. The mediators release performed with RBL sensitized with sera from allergic patients and stimulated with rDer p3, rDer p 3 S196A and natural Der p 3 were similar and lower than Der p 1 for concentration < 10 ng/ml. Conclusions: recombinant mature Der p 3 retained overall identity to its natural form in terms of structure and allergenicity. The instability and autolysis of Der p 3 drastically influence its IgE binding capacity. These results can be explain the considerable variations with the frequencies reactivity (16-100%) of natural Der p 3. The RBL assays demonstrated that the allergenicity of rDer p 3 is similar to rDer p 1 for the concentrations >10 ng /ml. [less ▲]

The variability of the geopotential height at 500 hPa simulated by General Circulation Models (GCMs) over Greenland is evaluated using an atmospheric circulation type classification. The GCM outputs for the current climate (20C3M) are first compared to reanalysis data over 1961-1990. The comparison shows that most of them simulate well the main circulation types but fail to reproduce their frequencies because of underestimations of circulation variability and biases in the mean geopotential height. GCM-based future projections do not individualise new circulation types but show a general increase of the geopotential height. Based on this approach, the correlation between surface temperature and atmospheric circulation offers a new way for estimating the Greenland ice sheet melt. [less ▲]

The present article is concerned by the main theoretical stages of the Error Correction Model (ECM) and its application. The first part starts with the analysis of the stationarity of the series followed by the cointegration test of Johansen and then the estimation of the ECM. The second part gives details of the application of this methodological approach on real data. This study has established that the current price of beans on the market is dependent on the price of white maize flour observed for two days in the first and the second quarter. [less ▲]

Genes encoding glycoprotein gH and gL homologues were localized in the genome of the gamma-herpesvirus bovine herpesvirus-4 (BHV-4). Both genes were sequenced and glutathione S-transferase fusion proteins were produced and used to immunize rabbits against the translation products of the two genes. The anti-gH serum recognized a protein with an apparent molecular mass (MM) of 110 kDa both in infected cells and in virions. This protein was sensitive to endo-beta-N-acetylglucosaminase-H (endoH) and endoglycosidase F-N-glycosidase F (endoF-PNGaseF) digestion. A protein with the same relative mobility was immunoprecipitated from infected cells radiolabelled with [3H]glucosamine which confirmed that this product (gp110), now designated BHV-4 gH, was glycosylated. Western blotting with the anti-gL serum detected in infected cells a product with an apparent MM ranging from 31-35 kDa and diffusely migrating protein species ranging from 45-65 kDa. Tunicamycin, monensin, endoH or endoF-PNGaseF treatments showed that both the 31-35 kDa and the 45-65 kDa proteins were glycosylated, gp31-35 being a precursor of the 45-65 kDa glycoprotein species. In radioimmunoprecipitation assays, the anti-gL serum immunoprecipitated from infected cells two glycosylated proteins with apparent MMs of 31-35 kDa (gp31-35) and 45-55 kDa (gp45-55). However a third glycoprotein, gp110, was also immunoprecipitated together with gp31-35 and gp45-55. gp110 and gp45-55 were subsequently confirmed to be virion glycoproteins corresponding to mature forms of BHV-4 gH and gL respectively. In addition, the present study clearly demonstrated complex formation between BHV-4 gH and gL both in virions and in infected cells. [less ▲]

The cataract corresponds to the total or partial opacification of the lens of the eye preventing the passage of the light. At present, the surgery is the only effective treatment to overcome the cataract. The surgical intervention consists in removing the cloudy lens and to replace it by an artificial intraocular lens (IOL). The in vivo implantation of these synthetic lenses involves the evaluation of several factors as their physico-chemical properties, their capacities to interact with lens epithelial cells and proteins, as well as their biocompatibility. During a previous study, we demonstrated major differences concerning the tackiness (atomic force microscopy), the cellular adhesion and the protein adsorption of various polymer disks intended for the manufacturing of intraocular lenses. The aim of this work was to correlate a histological analysis to a mass spectrometry imaging analysis performed on the same sample. To estimate the biocompatibility of the biomaterials, an animal testing was realized in rabbits. The various polymers were implanted subcutaneously. After one month, the 2 cm x 3 cm pieces of rabbit skin and underlying muscle with a 2 cm thickness were removed, fixed with formaldehyde 10% during six days, treated for the paraffin inclusion and stored at room temperature until use. Slices of 5 µm thickness were performed using a microtome. Paraffin was removed and tissue sections were washed in graded ethanol baths. The slices were then stained with the hematoxylin and eosin dyes. The analysis of stained sections showed different histo-morphological features according to the implanted polymer. For MALDI MSI purposes, on tissue protein digestion was performed using trypsin (1) and the MALDI matrix (α-cyanohydroxycinnamic acid, 5 mg/mL in ACN/0.2% TFA 70:30) was deposited using an ImagePrep automated sprayer (Bruker Daltonics, Bremen, Germany). Experiments were carried out using an UltraFlex II TOF/TOF mass spectrometer (Bruker Daltonics, Bremen, Germany). MALDI imaging can show the detection of different proteomic profiles according to the tested biomaterials, which may be considered as biocompatibility markers. The MALDI images of these markers are then correlated with the histo-morphological profiles. Consequently, mass spectrometry imaging can become a powerful tool in the evaluation of the biocompatibility of artificial implants in biomedical application. [less ▲]

The hepatitis C virus (HCV) glycoproteins E1 and E2 should be anchored in the viral membrane by their C-terminal domains. During synthesis, they are translocated to the endoplasmic reticulum (ER) lumen where they remain. The 31 C-terminal residues of the E1 protein and the 29 C-terminal residues of the E2 protein are implicated in the ER retention. Moreover, the E1 and E2 C termini are implicated in E1-E2 heterodimerization. We studied the E1 and E2 C-terminal sequences of 25 HCV strains in silico using molecular modeling techniques. We conclude that both C-terminal domains should adopt a similar and peculiar configuration: one amphipathic alpha-helix followed by a pair of transmembrane beta-strands. Several three-dimensional (3-D) models were generated. After energy minimization, their ability to interact with membranes was studied using the molecular hydrophobicity potentials calculation and the IMPALA procedure. The latter simulates interactions with a membrane by a Monte Carlo minimization of energy. These methods suggest that the beta-hairpins could anchor the glycoproteins in the ER membrane at least transiently. Anchoring could be stabilized by the adsorption of the nearby amphipathic alpha-helices at the membrane surface. The 3-D models correlate with experimental results which indicate that the E1-E2 transmembrane domains are involved in the heterodimerization and have ER retention properties. [less ▲]

Garlic has been known for its therapeutic effects for centuries and is used worldwide as a functional food. The concentration of the active molecules could be enhanced by a better knowledge of their biosynthesis. The precursor of these compounds, alliin (a sulfur amino-acid) has been obtained by chemical synthesis. However, this synthesis route also leads to a diastereoisomer as co-product. This work describes the development of an analytical method which allows the separation and quantification of the two diastereoisomers in order to determine in which proportion the natural form can be produced. The HPLC method which was optimized and validated by accuracy profile exploits an original stationary phase consisting of porous graphitic carbon (PGC). Furthermore, the developped method was used to separate the diastereoisomers of methiin, another garlic cysteine sulfoxide, and to analyse and aqueous extract of garlic. The ability to quantify the amount of natural alliin is valuable for further work on garlic molecules and their application for health protection. [less ▲]

Objective. To investigate whether shorter versions of the ADAM test, a screening questionnaire for andropause, provide better diagnostic value than the original tool. Methods. Five thousand and twenty-eight volunteer men aged 50-70 years attending a screening campaign for andropause, provided a fasting blood sample and completed the French ADAM test. Logistic regression analysis identified items that best predict andropause defined as serum free testosterone level below 70 ng/l. ROC curves assessed the diagnostic value of modified versions of the ADAM test, obtained by elimination of the less relevant predictors of andropause. Results. Only four items of the ADAM questionnaire may account for the diagnosis of andropause. These items concerned loss of height, decrease in libido and in enjoyment of life and deterioration in work performance. Item 9 was borderline significant. The area under the ROC curve for the short versions varied slightly from 0.555 to 0.560. As expected, model 6 has a greater specificity (56.02%) than the original tool while the efficiency increased slightly (54.85%). Conclusion. The modified versions of the ADAM test do not provide better diagnostic value than the original tool. Conclusion. The modified versions of the ADAM test do not provide better diagnostic value than the original tool. [less ▲]

Abstract In this paper, the results of the dynamic pull-in voltage characteristics of a micro-mirror using electrostatic actuation are analyzed. Based on torsional dynamic theory, appropriate equations are developed that allowed to give insight into the actuating voltage, switching time and other dynamic parameters. The analytical results are discussed in detail without and with considering air squeeze film damping, respectively. This is equivalent to assuming the mirror is operated in vacuum or at ambient pressure. When the effect of the damping is considered, the movement trajectory of the cantilever beam is changed, and the calculated results of the pull-in voltage and switching time are considerably different compared to those without considering damping. Therefore, the effect of the air squeeze film damping is an important factor in the design and fabrication of micro-electro-mechanical systems. Finally, the experimental results in the air environment are discussed and compared to the theoretical analysis. [less ▲]
