This study was carried out at the animal farm of Hanoi University of Agriculture, Vietnam to evaluate the growth performance and meat quality of stress negative Piétrain pigs. The study concerns the body weight (BW) of 116 pigs at 7.5 months of age and the ultrasound measurements on 83 live animals in order to determine backfat thickness, longissimus muscle depth and lean meat percentage (LM). Meat color (C.I.E L*, a* and b*), peak shear force (SF), pH at 24h (pH24) and at 45 minutes (pH45) post mortem were measured on 31 meat samples. Meat chemical composition (dry matter, protein, lipids and ash) was determined on 23 meat samples. All the data were analyzed according to a linear fixed model including gender effect (female and intact males) and Halothane genotype (CC and CT). The interaction between gender and genotype was not observed and therefore it was ignored from the final model. The results show that BW and LM were not significantly different between genotypes (P>0.21) while females were heavier than males (101.11 vs. 93.85 kg, P=0.0011). LM of female and male were respectively 63.27 and 63.56%. Gender and genotype didn’t affect meat quality and chemical composition (P>0.05) except pH24 (P=0.0011), a* (P<0.0001) and lipids (P=0.0012) for gender effect. The pH45 (6.50 and 6.45 for females and males) and pH24 (5.34 and 5.49 for females and males) were in the range corresponding to a normal meat. The obtained results show that stress negative Piétrain pigs have high lean meat percentage and satisfactory meat quality under tropical climatic conditions in Vietnam. [less ▲]

This study was conducted to evaluate the effects of genetic background and season on growth performance and semen quality of boars. Five genetic groups were evaluated, including stress-negative Piétrain boars with CC (PiCC) or CT (PiCT) halothane genotypes, and Piétrain x Duroc hybrid boars with various compositions (25% (PiDu25), 50% (PiDu50) or 75% (PiDu75) of Piétrain origin). The results showed that genetic group has a significant effect on growth performance and semen quality. The hybrid boars PiDu25, PiDu50 and PiDu75 had better growth rate, but lower lean <br />meat in comparison with pure stress-negative Piétrain, except PiDu75 boars. PiDu25, PiDu50 and PiCC boars demonstrated high semen quality. A season effect was observed on most of semen quality traits of pure stress-negative Piétrain as well as hybrid boars with different genetic constitution. Sperm concentration was lower in Summer and Autumn, higher in Winter and Spring. The Piétrain x Duroc hybrid boars, especially PiDu75 seem to be promising as terminal boars. [less ▲]

The aim of this study carried out from September to December 2010 was to evaluate the effects of Leuceana leucocephala leaves meal inclusion in the diets on growth performances, carcass and organs characteristics and economics results of growing indigenous Senegal chickens. One hundred and four (104) indigenous Senegal chicks of 4 weeks old were randomly allocated into four groups of 26 chicks each with similar body weight. Each group subdivided in two repetitions of 13 birds, corresponded to each of the four (4) dietary treatments LL0, LL7, LL14 and LL21 containing respectively 0, 7, 14 and 21% of Leuceana leaves meal in substitution of groundnut cake meal. During the experiment (5-17th week old), zootechnical parameters of birds and economical data were recorded and analyzed per dietary treatment. At the end of the 13 weeks trial, the final Live Body Weights (LBW) were 864 g, 1166.48 g, 905 g and 887.16 g/bird, the Average Daily Weight Gain (ADWG) were 7.77 g, 10.88 g, 8.15 g and 8.10 g/day, the Daily Feed Intake (DFI) of 39.86 g, 51 g, 40.39 g and 44.75 g/bird and the Feed Conversion Ratio (FCR) of 7.04, 5.54, 6.27 and 6.80 respectively for birds fed LL0, LL7, LL14 and LL21 diets. The Leuceana leaves meal inclusion in the diets up to 21% had not caused any adverse effect on LBW, ADWG, DFI, FCR, mortality, carcass and organs characteristics in birds compared to their controls. Apart from the dark yellowing of abdominal fat of carcasses from birds fed LL21 diet, significantly better growth performances, feed costs and economic margins were recorded in birds fed LL7 and LL14 diets. Thus, these two dietary treatments were the only most economically profitable (respectively 214 and 48 FCFA/kg carcass of additional profit) compared to the control. [less ▲]

Transforming growth factor (TGF) beta1 enhanced in vitro [3H]thymidine incorporation into C6 cells and reduced that of astrocytes in the presence of a high serum concentration. It concomitantly raised the gap junction intercellular communication (GJIC) in normal astrocytes but reduced the coupling of C6 cells, and respectively increased or decreased the proportion of P2-phosphorylated connexin (Cx) 43 isoform in these cells. Finally, octanol, which inhibited GJIC in both cell types, increased the thymidine incorporation in C6 cells, but neither altered the proliferation of astrocytes nor their response to TGFbeta1. These data indicate that an inhibition of gap junction intercellular communication, due to an altered phosphorylation of connexin 43, may contribute to the proliferative response of C6 glioblastoma cells to TGFbeta1.

The effect of salt concentration (NaCl) on growth, fluorescence, photosynthetic activities and pigment content of the cyanobacterium Arthrospira platensis has been investigated over 15 days. It has been observed that high NaCl concentration induces an increase of the growth, photosynthetic efficiency (alpha), phycobilin/chlorophyll ratio and a slight decrease of dark respiration and compensation points. Moreover, high NaCl concentration enhances photosystem II (PSII) activity compared to photosystem I (PSI). Results show that the phycobilin-PSII energy transfer compared to the chlorophyll-PSII (F-695,F-600/F-695,F-440) increases. However, data obtained about the maximal efficiency of PSII photochemistry are controversial. Indeed, the Fv/Fm ratio decreases in salt adapted cultures, while at the same time the trapping flux per PSII reaction center (TR0/RC) and the probability of electron transport beyond QA (Psi(0)) remain unchanged at the level of the donor and the acceptor sites of PSII. This effect can be attributed to the interference of phycobilin fluorescence with Chl a when performing polyphasic transient measurements. [less ▲]

Despite considerable progress in recent years, the underlying mechanisms responsible for the failure of axonal regeneration after spinal cord injury (SCI) remain only partially understood. Experimental data have demonstrated that a major impediment to the outgrowth of severed axons is the scar tissue that finally dominates the lesion site and, in severe injuries, is comprised of connective tissue and fluid-filled cysts, surrounded by a dense astroglial scar. Reactive astrocytes and infiltrating cells, such as fibroblasts, produce a dense extracellular matrix (ECM) that represents a physical and molecular barrier to axon regeneration. In the human situation, correlative data on the molecular composition of the scar tissue that forms following traumatic SCI is scarce. A detailed investigation on the expression of putative growth-inhibitory and growth-promoting molecules was therefore performed in samples of post-mortem human spinal cord, taken from patients who died following severe traumatic SCI. The lesion-induced scar could be subdivided into a Schwann cell dominated domain which contained large neuromas and a surrounding dense ECM, and a well delineated astroglial scar that isolated the Schwann cell/ECM rich territories from the intact spinal parenchyma. The axon growth-modulating molecules collagen IV, laminin and fibronectin were all present in the post-traumatic scar tissue. These molecules were almost exclusively found in the Schwann cell-rich domain which had an apparent growth-promoting effect on PNS axons. In the astrocytic domain, these molecules were restricted to blood vessel walls without a co-localization with the few regenerating CNS neurites located in this region. Taken together, these results favour the notion that it is the astroglial compartment that plays a dominant role in preventing CNS axon regeneration. The failure to demonstrate any collagen IV, laminin or fibronectin upregulation associated with the astroglial scar suggests that other molecules may play a more significant role in preventing axon regeneration following human SCI.

Growth-related changes in pulmonary function values were investigated in 20 healthy French Alpine goats, aged between 20 and 550 days, weighing 7-55 kg. Pulmonary ventilation, mechanics of breathing and arterial oxygen tension were measured using standardized techniques and methods adapted for goats of different body sizes. The Ppl values and the tI/tTOT ratio showed no significant changes with age and body size. The ventilation values (Vt, Ve, mVI and mVE) increased linearly with growth. There was a significant correlation of age and body weight with dynamic lung compliance (Cdyn), total pulmonary resistance (RL), viscous work of breathing (Wvis tot) and minute viscous work (Wvis min) throughout the age range studied. Cdyn, Wvis tot and Wvis min increased and RL decreased with age and body weight. Arterial blood gases (PaO2 and PaCO2) did not show significant changes over the age range studied. Regression equations for each pulmonary function parameter are given with body weight as the independent variable. Data for the mechanics of breathing were compared with those elsewhere for cattle, horses, man and dogs. [less ▲]

a) Einleitung Noroviren sind derzeit die häufigsten Gastroenteritiserreger. Durch ihre niedriger infektiöse Dosis und Umweltstabilität verursachen sie häufig Ausbrüche in Krankenhäusern und anderen Gemeinschaftseinrichtungen. Wir berichten über den größten Norovirusausbruch in einem Münchner Krankenhaus der vergangenen Jahre mit über hundert infizierten Patienten und insgesamt 28 betroffenen Mitarbeitern aus verschiedenen Bereichen. b) Material/Methoden Wir wiesen Noroviren GII durch real time Amplifikation eines 94 bp am 3´Ende des Nichtstruktur Polyprotein nach. Sieben positive Proben, aus verschiedenen Bereichen des Klinikums einschließlich zweier Außenstellen, sowie Proben von 2 Küchenmitarbeitern wurden sequenziert. Dabei untersuchten wir 1110 bp, bestehend aus Polymerase- und Capsidsequenzen. Das Ausbruchsmanagement bestand aus einer task force, die neben dem ärztlichen Direktor aus Ärzten, Pflegekräften, Hygieniker und Virologen Apotheke, Einkauf, und Küchenbereich bestand. Zu den Maßnahmen gehörten unter anderem Abfrage aller betroffenen Stationen mit mindestens täglicher Aktualisierung der line-list, Umstellen desinfizierender Maßnahmen, sehr eng kontrolliertes Patientenmanagement (Verlegungen nur nach Rücksprache mit der Hygiene), Begehung aller betroffenen Stationen und der Küche, Abfrage der Nahrungsmittelaufnahme durch Fragebögen, Fortbildung des Personals und enge Kooperation mit den zuständigen Behörden. c) Ergebnisse Am 15.06. traten bei Patienten erstmalig Übelkeit und Erbrechen auf, am Folgetag wurde bei den ersten Patienten Noroviren in Stuhlproben nachgewiesen. Die letzte Neuinfektion wurde am 23.06. registriert, so dass der Ausbruch bereits am 04.07. in Absprache mit dem RGU München für beendet erklärt wurde. Insgesamt wurde Norovirus RNA bei 116 Patienten auf 34 Stationen sowie 28 Mitarbeitern nachgewiesen. Zweiundzwanzig Mitarbeiter waren in der direkten Patientenversorgung tätig, eine Mitarbeiterin arbeitete im Laborbereich. Fünf der Mitarbeiter waren im Küchenbereich beschäftigt und sind damit die wahrscheinlichste Infektionsquelle. Sie gaben keine bzw. nur wenig ausgeprägte Symptome an, mit denen sie weiterarbeiteten. In den bisher untersuchten Lebensmittelrückstellproben konnten keine Noroviren detektiert werden. Alle untersuchten Sequenzen entsprachen einem rekombinanten GII.g/GII.I Stamm. Die ähnlichsten publizierten Sequenzen unterscheiden sich nur durch 17 Nukleinsäure-, und 3 Aminosäureaustausche d) Schlussfolgerungen Wir beschreiben hier den größten Norovirenausbruch in Münchener Kliniken der letzten Jahre. Er breitete sich rasch aus und trat außerhalb der üblichen Norovirussaison auf. Durch schnelle Einleitung strikter Hygienemaßnahmen und einer engen Überwachung der betroffenen Stationen fanden wir nach 10 Tagen keine Neuinfektionen und konnten den Ausbruch zeitnah für beendet erkären. Erstmalig wiesen wir den rekombinanten Stamm GII.g/II.1 in unserem Universitätsklinikum nach. Fehlende oder niedrige Immunität der exponierten Personen könnte die initial rasche Ausbreitung begünstig haben. Zusammenfassend zeigen unsere Daten, dass bei Gastroenteritisfällen auch in den Sommermonaten mit Noroviren gerechnet werden muss. Diese können auch von oligo- oder asymptomatischem Personal ausgehen. Schnelle Erregerdiagnose und entsprechende Hygienemaßnahmen sind wesentlich in der Bekämpfung der Infektion. [less ▲]
