Average White Band poster, ca. 2000

The Average White Band's debut album, Show your hand, was released in 1973. The "classic funk and R & B" band included members Alan Gorrie, Owen "Onnie" McIntyre, Malcolm "Mollie" Duncan, Roger Ball, Robbie McIntosh, and Mike Rosen. Rosen was quickly replaced by Hamish Stuart. The band, comprised of Scotsmen, released a second album in 1974 that featured the US number 1/UK Top 10 single "Pick up the Pieces". That same year, Robbie McIntosh died of a heroin overdose and was replaced by Steve Ferrone. The song "Cut the Cake" from their third album made the US top 10, and subsequent releases in the late 1970s and early 1980s proved successful. The members largely pursued individual projects in the years that followed, but re-formed in 1989 (with original members Gorrie, Ball and McIntyre, and new members Alex Ligertwood and Eliot Lewis) and released the album Aftershock. Over the years, the band's members have changed, and the band is currently comprised of Onnie McIntyre, Rocky Bryant, Alan Gorrie, Fred "Freddy V" Vigdor and Klyde Jones. Their most recent album, Times Squared, was released in 2009.

Diversity Discourse and the Ontario Educator: The Understandings of Race and Whiteness Among New White Ontario Teachers

As a recent teacher education graduate, I have been left with more questions than answers about how to create and maintain an equitable and antioppressive classroom. These complicated questions of equity laid the groundwork for this study, which explored how new teachers understood diversity, specifically whiteness, and how they connected these perceptions to their course-related experiences in their teacher education program. Using a qualitative approach, this study problematized the lack of critical discussions around diversity taking place in Ontario teacher education courses. Through purposive, homogenous sampling, 7 new Ontario educators participated in a semistructured interview that focused on their experiences as teacher candidates and new teachers and their understandings and ideas regarding diversity, race, and more specifically, whiteness. The findings suggest that the greater Canadian discourse surrounding multiculturalism impacts the everyday diversity talk of the participants, and that problematic ideas of acceptance and tolerance are common. The findings also show a strong discomfort and unfamiliarity among the participants with the terms whiteness and white privilege. Finally, the results also revealed that new teachers have limited experience in their teacher education to discuss and learn about diversity, particularly critical discussions about race and privilege. Through this investigation, I aimed to bring attention to the necessity of having these critical, albeit difficult, discussions around diversity and whiteness in order to support new, predominately white, teachers.

Sélection de gènes de référence pour la normalisation des expériences de PCR quantitative dans un modèle de dysfonction diastolique de lapin

La dysfonction diastolique du ventricule gauche (DDVG) réfère à une rigidité ainsi qu’à des troubles de relaxation au niveau de ce ventricule pendant la phase de la diastole. Nos connaissances sur les mécanismes moléculaires sous-jacents de cette pathologie demeurent limités. Les analyses géniques sont indispensables afin de bien identifier les voies par lesquelles cette maladie progresse. Plusieurs techniques de quantification de l’expression génique sont disponibles, par contre la RT-qPCR demeure la méthode la plus populaire vu sa haute sensibilité et de ses coûts modérés. Puisque la normalisation occupe un aspect très important dans les expériences de RT-qPCR, nous avons décidé de sélectionner des gènes montrant une haute stabilité d’expression dans un modèle de DDVG de lapin. Nous avons alors exposé 18 lapins blancs soit à une diète normale (n=7) ou bien à une diète hypercholestérolémiante additionnée de vitamine D2 (n=11). La DDVG a été évaluée par des mesures échocardiographiques. L’expression de l’ARNm de dix gènes communément utilisés dans la littérature comme normalisateur (Gapdh, Hprt1, Ppia, Sdha, Rpl5, Actb, Eef1e1, Ywhaz, Pgk1, et G6pd) a été mesurée par RT-qPCR. L’évaluation de leur stabilité a été vérifiée par les algorithmes de geNorm et Normfinder. Sdha et Gapdh ont obtenu les meilleurs scores de stabilité (M<0.2) et ont été suggérés par le geNorm, comme meilleure combinaison. Par contre, l’utilisation de Normfinder mène à la sélection d’Hprt1 et Rpl5 comme meilleure combinaison de gènes de normalisation (0.042). En normalisant par ces deux combinaisons de gènes, l’expression de l’ARNm des peptides natriurétiques de type A et B (Anp et Bnp), de la protéine chimiotactique des monocytes-1 (Mcp-1) et de la sous unité Nox-2 de la NADPH oxydase ont montré des augmentations similaires chez le groupe hypercholestérolémique comparé au groupe contrôle (p<0.05). Cette augmentation d’expressions a été corrélée avec plusieurs paramètres échocardiographiques de DDVG. À notre connaissance, c’est la première étude par laquelle une sélection de gènes de référence a été réalisée dans un modèle de lapin développant une DDVG.

L’injection percutanée de cartilage sur le dorsum nasal chez le lapin

Abstract: Objective: To compare the long-term viability of percutaneously injected crushed auricular cartilage to surgically implanted cartilage in the rabbit. Methods: Auricular cartilage was harvested bilaterally in 10 New Zealand white rabbits. A 1 cm2 cartilage graft was harvested and implanted surgically on the upper nasal dorsum. The remaining cartilage was crushed and percutaneously injected on the lower nasal dorsum. Volume and mass of each graft were compared between pre-implantation and after 3 months of observation. A histological study was conducted to evaluate chondrocyte viability and degree of fibrosis on the grafts. Results: Mass and volume remained similar for surgically implanted cartilage grafts. Mass and volume diminished by an average of 47% and 40% respectively after 3 months for the injected crushed cartilage grafts. Chondrocyte viability was an average of 25% lower in the injected grafts. Conclusion: Cartilage injection is a promising technique that must be refined to increase long term chondrocyte viability. Developing an appropriate injection apparatus would improve this technique.

White Spot Syndrone Virus in Penaeids: Histopathology, Development of Polyclonal Antisera and a Cocktail Vaccine

The present study is the first comprehensive approach towards histopathology of White Spot Syndrome Virus (WSSV) in Penaeus indicus. WSSV could be demonstrated in the nuclei of all tissues, except those of midgut, subjected of electron microscopic observation. They were the nuclei of gill, foregut, heart, hepatopancreatic connective tissue, hindgut, nerve and dorsal aorta. A comparison was made between the electron microscopic and histopathological observations and a greater degree of correlation between the two in depicting the severity of the infection of the infection was unraveled. The study also illustrated variations in response and susceptibility of various tissues to WSSV infection. Accordingly, out of the tissues investigated, gill, foregut, hindgut and dorsal aorta exhibited advanced viral multiplication than the other tissues such as heart, midgut, nerve and hepatopancreas. Even though hepatocytes were not infected the connective tissue nuclei were packed with virions.

Antiviral property of marine actinomycetes against White Spot Syndrome Virus in penaeid shrimps

Aquaculture farms, particularly in Southeast Asia are facing severe crisis due to increasing incidences of White Spot Syndrome Virus (WSSV). Actinomycetes have provided many important bioactive compounds of high prophylactic and therapeutic value and are continually being screened for new compounds. In this communication, the results of a study made to determine the effectiveness of marine actinomycetes against the white spot disease in penaeid shrimps are presented. Twenty-five isolates of actinomycetes were tested for their ability to reduce infection due to WSSV among cultured shrimps. When these actinomycetes were made available as feed additives to the post-larvae of the black tiger shrimp Penaeus monodon for two weeks and challenged with WSSV, the post challenge survival showed variations from 11 to 83%. However, six isolates have shown to be the most potential candidates for further study.

A study of the white electroluminescence in ZnS:Cu,Pr,Cl phosphors

The method of preparation of ZnS phosphors doped with praseodymium and copper is given. The electroluminescence (EL) spectrum of ZnS:Pr,Cl has two broad bands at 470 and 570 nm. ZnS:Cu,Pr,Cl gives white emission with spectral peaks at 470, 520, 570 and 640 nm. The EL spectra of both types of phosphor exhibit a conspicuous colour shift as the frequency of the excitation voltage is varied. Detailed investigations show that the relative intensities of spectral peaks are strongly dependent on the frequency of the excitation voltage. The colour shift is explained on the basis of the Schon-Klasens model.
