The implantation of a penile prosthesis frequently results in a reduction of the erectile length compared with natural erections. Some patients complain about this fact and their satisfaction at prosthesis assisted sexuality is significantly diminished. Obviously, the degree of complaint is not proportional to the objective degree of penile reduction. For an objective reality to lead to complaints, subjective criteria of appreciation have to intervene. A survey questionnaire completed by 39 implanted patients and 30 partners shows that complaints about the size of the implanted penis are mostly related to a social representation of sexuality which associates the male erotic value to criteria of erectile length, spontaneity and “naturalness”. This representation also tends to be projected in the partner’s mind, independently of her actual attitudes and feelings. Therefore, the injurious impact of penile reduction on satisfaction at the prosthetic device seems to be inseparable from a global representation of prosthetic sexuality which is experienced as a “parodic”, “reduced” virility. The reduced size of the penis focuses feelings of vexation which cannot be reduced to simple functional considerations, it embodies the painful and complex image of a lost virility. From this point of view, psychosexological counselling would be indicated in order to help some couples to improve their adaptation to penile prosthesis. Moreover, an Attitude scale towards Penile Implant (API) derived from the survey questionnaire might enable the identification of risk-patients. [less ▲]

Suite à une conscientisation de plus en plus forte de la problématique environnementale, la production de biocarburants s’est développée un peu partout dans le monde. C’est en Wallonie que la plus grande usine de production de bioéthanol de Belgique, BioWanze, a été inaugurée, en décembre 2008. Le ProtiWanze® est différent des autres co-produits issus de la fabrication de bioéthanol. En effet, il est élaboré à partir d’un substrat unique, le froment alors que le plus souvent les usines de production de biocarburants utilisent comme matières premières le maïs, le seigle, l’orge, la canne à sucre, seuls ou en mélanges en proportions variables suivant les prix du marché. Par conséquent, ces co-produits destinés à l’alimentation animale ont des caractéristiques variant au gré des mélanges sélectionnés alors que le ProtiWanze® est relativement stable. Les principaux atouts du ProtiWanze® sont sa teneur en énergie (1130 VEM) et sa teneur en protéines (280 g Matière azotée totale/kg de matière sèche en moyenne). Il est pauvre en matière sèche (teneur moyenne de 27%) et se présente sous forme liquide, ce qui réduit sa valeur d’encombrement au niveau du rumen. L’incorporation du ProtiWanze® dans l’alimentation des bovins en Wallonie a fait l’objet d’un suivi par l’Université de Liège et a été testé chez les vaches laitières, les vaches allaitantes et les taureaux à l’engrais et ce 2 années consécutives. Les résultats tant zootechniques qu’économiques liées à l’utilisation de cet aliment font l’objet de cette présentation. [less ▲]

La flambée du prix des aliments pour bétail pénalise de plus en plus le revenu par exploitation, vu la part importante des coûts alimentaires dans l’économie de l’exploitation. Pour diminuer ce coût, diverses pistes peuvent être suivies : favoriser l’autonomie, en diminuant l’achat d’aliments en-dehors de l’exploitation et valoriser au mieux les fourrages - ou incorporer des co-produits issus de l’industrie qui sont moins coûteux. Dans cette optique, en partenariat avec la Région Wallonne et BioWanze, le département Clinique des Animaux de Production de l’Université de Liège a étudié les possibilités de valorisation du ProtiWanze®, co-produit de la fabrication de bio-éthanol, dans l’alimentation de bovins viandeux pendant 2 années consécutives. Afin d’étudier l’impact de son utilisation en spéculation viandeuse, 3 exploitations de vaches allaitantes (2 BB et 1 Blonde d’Aquitaine en 2011, 3 exploitations BB en 2012) et 2 exploitations de taureaux à l’engrais (1 BB et 1 Blonde d’Aquitaine en 2011, 2 BB en 2012) ont été suivies 1 fois par mois pendant la période hivernale, 2 années consécutives. La production des animaux a été évaluée par différents indicateurs. Ainsi, les scores de santé, à savoir le score d’état corporel (SC), le remplissage du rumen (RR), le score de consistance fécale (CF), la fraction fécale non digérée (FF) et le score de locomotion (SL), ont été relevés lors de chaque visite, durant 4 mois. A cette occasion, du jus de rumen a été prélevé et analysé afin de vérifier l’impact de l’utilisation du ProtiWanze® sur la santé du rumen. L’influence sur la reproduction a été évaluée par la récolte des données suivantes: intervalle vêlage - vêlage, nombre de veau/vache/an, nombre d’inséminations nécessaires pour obtenir une gestation, âge au premier vêlage. Chez les taureaux, l’indice de consommation, le gain quotidien moyen et le rendement à l’abattage ont été calculés. L’effet de l’incorporation du ProtiWanze® dans l’alimentation des vaches allaitantes et des taureaux à l’engrais n’a eu aucun effet négatif. Au contraire, le ProtiWanze® a permis de bien valoriser la ration à base de fourrages sans induire d’inrumination ou d’encombrement du rumen. L’avantage moyen lié au ProtiWanze® par rapport à un apport de protéines par un mélange 1/3 tourteau de soya+2/3 tourteau de colza est de 8 à 10 cents en 2011 respectivement pour les vaches allaitantes et les taureaux et de 3 à 4 cents en 2012. Cette faible différence calculée en 2012 entre les rations (ProtiWanze® vs TS+TC) est liée à la diminution de la teneur en protéines du ProtiWanze® (262 g MAT/kg MS en 2012 vs 282 g MAT/kg MS en 2011) alors que son prix a augmenté (de 170 €/kg de MS en 2011 à 200 €/kg de MS en 2012). Néanmoins il ne faut pas oublier que la comparaison de prix ne tient compte que de l’apport en protéines du ProtiWanze® sans prendre en compte sa richesse en énergie. Il reste néanmoins que le ProtiWanze® semble améliorer la digestion de la ration et promouvoir la production laitière chez les vaches allaitantes. [less ▲]

To verify whether introducing Protiwanze® (PW) in dairy cattle diet was economically valuable, 4 herds (N cows: 87± 13) have been followed up for 2 years (2011 and 2012). They received successively two diets differing in PW content for 4 weeks, including a 7-day transition: 10% and 15% for Herd 1,2, and 3 while Herd 1 received 0 and 10% on a dry matter basis. Both concentrations were distributed alternatively and repeated twice, each cow being its own control. Rations were formulated to meet energy and nitrogen requirements. During each testing period, animals were scored (Body Condition, Rumen Fill, Fecal Consistency, Undigested Fraction) according to Zaaier (2001) and their milk production and composition determined by the Dairy Herd Improvement. Ruminal juices were sampled on 5 cows and checked for subacute ruminal acidosis. Reproduction performance was analyzed. Introducing PW in dairy cows diet did not change milk production, reproduction performance nor induce subacute ruminal acidosis. Economically, it decreased feeding costs but this advantage was lower in 2012 as protein content of Protiwanze was reduced while its price increased. [less ▲]

The protochlorophyllide transformation process was investigated by using comparative analysis of 77 K fluorescence spectral changes occurring in isolated bundle sheath (BS) cells of etiolated Zea mays leaves after being exposed to a 200 ms saturating flash. Deconvolution analysis of the fluorescence spectra showed essential differences in the ratio of protochlorophyll(ides) and chlorophyll(ides) spectral forms indicating for BS cells to have a characteristic pathway of protochlorophyllide transformation. Bundle sheath cells showed a high ratio between non-photoactive protochlorophyll(ide)-F632 and photoactive protochlorophyllide-F655. In those cells, the 200 ins flash triggered a preferential formation of chlorophyll(ide)-F675 which remained stable in the dark for at least 90 min. Isolated BS cells showed an accumulation of chlorophyll(ide)-F675 resulting in the formation of inactive photosystem II. However for mesophyll cells of intact leaves, it was found to have a high ratio between photoactive and non-photoactive protochlorophyll(ide), showing the succession of chlorophyll(ide) forms usually known in C-3 plants. Protochlorophyllide phototransformation pathway in BS cells related to early stages of plastid differentiation triggered by light may indicate specific conditions for PSII assembly process leading to inactive PSII forms.

Protochlorophyllide (Pchlide) reductases are key enzymes in the process of chlorophyll biosynthesis. In this review, current knowledge on the molecular organization, substrate specificity and assembly of the light-dependent reduced nicotinamide adenine dinucleotide phosphate:Pchlide oxidoreductases are discussed. Characteristics of light-independent enzymes are also described briefly, and the possible reasons for the selection of light-dependent enzymes during the course of evolution are discussed. [less ▲]

The fast (1 min) regeneration process of the photoactive Pchlide forms after a light flash was studied in etiolated wheat leaves, and this process was simulated in vitro by incubating etioplast inner membranes of wheat with excess NADPH or NADP(+). The 77 K fluorescence spectra were recorded after flash illumination, dark incubation and a subsequent flash illumination of the samples. A non-photoactive Pchlide form with an emission maximum at 650 nm was transiently detected in leaves during regeneration of a photoactive Pchlide form with an emission maximum at 654 nm. Gaussian deconvolution of fluorescence spectra of isolated membranes showed that this 650 nm form appeared in conditions of excess NADP(+), as suggested in previous studies. Additionally a Pchlide form emitting at 638.5 nm was detected in the same conditions. The analysis of the spectra of leaves at different times after a flash indicated that these two non-photoactive forms are involved as intermediates in the regeneration of photoactive Pchlide. This regeneration is in correlation with the production of the Chlide form emitting at 676 nm. The results demonstrate that, in vivo, part of the NADPH:protochlorophyllide oxidoreductase is reloading with nonphotoactive Pchlide on a fast time-scale and that the 676 nm Chlide form is the released product of the phototransformation in this process.

This protocol describes a nonisotopic method for high-resolution investigation of the kinetics of RNA within the cell. This involves the incorporation of bromouridine-5'-triphosphate into RNA of living cells by lipofection followed by immunocytological detection of BrRNAs. The use of the same antibody identified either with fluorescence or with gold particles revealed the three-dimensional organization of sites containing labeled RNAs or their precise localization by using confocal and ultrastructural microscopy, respectively. Comparison of three-dimensional reconstruction obtained from the series of optical sections and ultrathin sections was extremely fruitful to describe topological and spatial dynamics of RNAs from their synthesis site inside the nucleus to the cytoplasm. Combined with immunolocalization of proteins involved in different nuclear activities and with highly resolved three-dimensional visualizations of the labelings, this method should also provide a significant contribution to our understanding of the functional, volumic organization of the cell nucleus. The entire protocol can be completed in approximately 10 d. [less ▲]
