Effects of dietary restraint and oral contraceptives on bone strength and bone turnover in young women

ABSTRACT Introduction The purpose of this study was to assess specific osteoporosis-related health behaviours and physiological outcomes including daily calcium intake, physical activity levels, bone strength, as assessed by quantitative ultrasound, and bone turnover among women between the ages of 18 and 25. Respective differences on relevant study variables, based on dietary restraint and oral contraceptive use were also examined. Methods One hundred women (20.6 ± 0.2 years of age) volunteered to participate in the study. Informed written consent was obtained by all subjects prior to participation. The study and all related procedures were approved by the Brock University Research Ethics Board. Body mass, height, relative body fat, as well as chest, waist and hip circumferences were measured using standard procedures. The 10-item restrained eating subscale of the Dutch Eating Behaviour Questionnaire (DEBQ) was used to assess dietary restraint (van Strien et al., 1986). Daily calcium intake was assessed by the Rapid Assessment Method (RAM) (Hertzler & Frary 1994). Weekly physical activity was documented by the 4-item Godin Leisure-Time Exercise Questionnaire (Godin & Shephard 1985). Bone strength was determined from the speed of sound (SOS) as measured by QUS (Sunlight 7000S). SOS measurements (m/s) were taken of the dominant and non-dominant sides of the distal one third of the radius and the mid-shaft of the tibia. Resting blood samples were collected from all subjects between 9am and 12pm, in order to evaluate the impact of lifestyle factors on biochemical markers of bone turnover. Blood was collected during the early follicular phase of the menstrual cycle (approximately days 1-5) for all subjects. Samples were centrifliged and the serum or plasma was aliquoted into separate tubes and stored at -80°C until analysis. The bone formation markers measured were Osteocalcin (OC), bone specific alkaline phosphatase (BAP) and 25-OH vitamin D. The bone resorption markers measured were the carboxy (CTx) and amino (NTx) terminal telopeptides of type-I collagen crosslinks. All markers were assessed by ELISA. Subjects were divided into high (HDR) and low dietary restrainers (LDR) based on the median DEBQ score, and also into users (BC) and non-users (nBC) of oral contraceptives. A series of multiple one way ANOVA's were then conducted to identify differences between each set of groups for all relevant variables. A two-way ANOVA analysis was used to explore significant interactions between dietary restraint and use of oral contraceptives while a univariate follow-up analysis was also performed when appropriate. Pearson Product Moment Correlations were used to determine relationships among study variables. Results HDR had significantly higher BMI, %BF and circumference measures but lower daily calcium intake than LDR. There were no significant differences in physical activity levels between HDR and LDR. No significant differences were found between BC and nBC in body composition, calcium intake and physical activity. HDR had significantly lower tibial SOS scores than LDR in both the dominant and non-dominant sites. The post-hoc analysis showed that within the non-birth control group, the HDR had significantly lower tibial SOS scores of bone strength when compared to the LDR but Aere were no significant differences found between the two dietary restraint groups for those currently on birth control. HDR had significantly lower levels of OC than LDR and the BC group had lower levels of BAP than the nBC group. Consistently, the follow-up analysis revealed that within those not on birth control, subjects who were classified as HDR had significantly (f*<0.05) lower levels of OC when compared with LDR but no significant differences were observed in bone turnover between the two dietary restraint groups for those currently on birth control. Physical activity was not correlated with SOS scores and bone turnover markers possibly due to the low physical activity variability in this group of women. Conclusion This is the first study to examine the effects of dietary restraint on bone strength and turnover among this population of women. The most important finding of this study was that bone strength and turnover are negatively influenced by dietary restraint independent of relative body fat. In general, the results of the present thesis suggest that dietary restraint, oral contraceptive use, as well as low daily calcium intake and low physical activity levels were widespread behaviours among this population of college-aged women. The young women who were using dietary restraint as a strategy to lose weight, and thus were in the HDR group, despite their higher relative body fat and weight, had lower scores of bone strength and lower levels of markers of bone turnover compared to the low dietary restrainers. Additionally, bone turnover seemed to be negatively affected by oral contraceptives, while bone strength, as assessed by QUS, seemed unaffected by their use in this population of young women. Physical activity (weekly energy expenditure), on the other hand, was not associated with either bone strength or bone tiimover possibly due to the low variability of this variable in this population of young Canadian women.

Lini Richarda Grol Fonds, 1946-2007

Lini Richarda Grol was originally born in Nijmegen, Netherlands in 1913 and immigrated to Canada in 1954 after working as a nurse in South America for three years from 1951 to 1954. She was granted her first Canadian passport in 1961 and worked full-time as nurse at the Welland County Hospital. While nursing she would enroll in writing courses at McMaster University and Ryerson Polytechnical Institute, now Ryerson University. Eventually she decided to dedicate herself to her writing and artwork and began to only work as a nurse part-time and then later opened the Fonthill Studio to devote herself to her writing and artwork full-time. Her status as an immigrant and career as a nurse provided inspiration for much of her writing and she frequently tackles the experience of the female immigrant in her works. Her first publication was in 1938 in a small literary and women’s magazines in Holland and Belgium and her first work of poetry was entitled Stive Gedachten. None of these publications exist in this archive. Her most well-known publication, Liberation, centers around her experiences leading up to and after the liberation of Holland during World War II. Grol was, and continues to be a prolific writer in the Niagara Region and has been published in the Welland Tribune, Pelham Herald, Thorold News, Parent Magazine, Dunville Chronicle, and various Christian publications and literary newsletters and journals. Grol also started her own poetry magazine entitled Canadian Poets Pen Club to help aspiring writers get published. Perhaps her most recognized achievement was the inclusion of one of her poems and the recognition of her novel Liberation into the Thank You Canada Day celebration in May 1970. Grol participated in many local writers’ groups such as the Welland Writer’s Club, and the Canadian Author’s Association. Grol was membership secretary for the Canadian Author’s Association in 1984. She also founded a writer’s club in 1995 in her retirement home, Holland Christian Homes where members meet to talk about their poems and short stories either in English or Dutch. Participating in and creating a writers’ community is integral to Grol’s identity as an author and can be related to the feelings of isolation she felt as an immigrant to Canada. Grol also hosted her own television shows entitled Discovery with Lini Grol which featured guests, usually local artists and writers, and Holland en Hollanders a cultural program for Dutch immigrants. Grol’s most recent activities include the publication of a one act play entitled Peppermint Problems [1996] and a short story entitled “When our War started in Rotterdam” [2004]. In 1994, she moved to Brampton, Ontario into a Christian retirement center called Holland Christian Homes. For further biographical information about Grol see two books contained within this collection Women of Action [1976] and Something About the Author [1976].

Letter to Mr. Henry H. Collier, 1837

Henry Haight Collier, was born in Howard, Steuben County, N. Y., November 28, 1818. His father, Richard Collier, was from Green County, in the same State. His grandfather, Isaac Collier, and his great-grandfather were originally from England. His mother, Mary Haight, was of Dutch origin. In 1835, Henry went to St. Catharines, where his elder brother, Richard Collier, resided. He spent two years at Grantham Academy, and then returned to Steuben County, to read law in Bath, with Edward Howell, and subsequently with Hammond and Campbell. Mr. Collier never opened a law office. He studied law for two years and in 1839 he went to Texas where he was connected with the State and Treasury Departments. In 1845 Mr. Collier returned to St. Catharines and opened a general store called St. Catharines Agricultural Works with his brother. The store remained open until May, 1877. He added the manufacturing of lumber in 1850, and manufacturing of agricultural implements in 1869. He built one of the first saw mills on the canal, on Lock No. 5, in St. Catharines. In July, 1877, he was appointed Collector of Customs. He became a Village Councilor for St. Paul’s Ward in 1859, and held that office from fifteen to twenty years. He was Deputy Reeve and member of the County Council for two terms. He was the Mayor of St. Catharines in 1872 and 1873. He was also Chairman of the Board of Water Commissioners of the city, during the time that the works were being built. He was a Justice of the Peace for twenty years or more. Mr. Collier was affiliated with the Reform Party and he was a Knight Templar in the Masonic fraternity and an Odd Fellow. He was also active in the Methodist Church. On June 1, 1858, he married Cornelia, daughter of Moses Cook, of "Westchester Place," St. Catharines, and had a daughter and son. Mary J. (married name: Mrs. Frank Camp) was a graduate of the Female Seminary at Hamilton, and Henry Herbert was a student in the University of Toronto. Henry H. Collier died on July 15, 1895 and is buried in Victoria Lawn Cemetery, St. Catharines, Ontario. Sources: www.accessgeneology.com "Historical Profiles from Victoria Lawn Cemetery" by Paul E.

Sir Isaac Brock Facial Reconstruction Project, n.d.

Christian Cardell Corbet, a descendant of Guernsey, Channel Islands, was born in 1966 at Pickering Beach on Lake Ontario. He developed his talents as a landscape artist and at the young age of 14 he began his informal education in commercial signage from his paternal grandfather. He studied at the University of Guelph and McMaster University Anatomy Laboratory. Corbet traveled to England where he began to experiment more in abstraction and non-objective work. In 1995, he presented a portrait of HM Queen Elizabeth the Queen Mother at Clarence House. This brought his career to an international level. He also creates two-dimensional works and has received acclaim for his bronze art medallions. He has gained international recognition as a Forensic Artist working as Artist in Residence for the University of Western Ontario. He does facial reconstructions for special assignments. These original drawings relate to a sculpted medallion of Brock which was authorized by Sir Geoffrey Rowland, Bailiff, Guernsey, Channel Islands and Minister of Education of the States of Guernsey. This is the first time in known recorded history that a forensic analysis and sculpture has been created to accurately depict the facial likeness of Sir Isaac Brock. This project has been established to mark the 2012 anniversary of the death of Brock.

La Petite danseuse de quatorze ans : une analyse de la fonction subversive de l’œuvre

La Petite danseuse de quatorze ans (1881) de l’artiste français Edgar Degas (1834-1917) représente et déforme plusieurs catégories sociales et artistiques de son époque. L’œuvre peut ainsi être lue comme une mise en abyme à la fois des changements sociaux et des peurs qu’ils suscitent quant aux redéfinitions du rôle et de la place de la sculpture dans l’art et de l’art, des classes sociales, de la science et de la femme dans la société qui s’opèrent dans la seconde moitié du 19e siècle. D’une mise en contexte de l’œuvre à une analyse de la figure de la ballerine, en passant par une lecture du monde de la poupée et de la criminalité, nous chercherons à montrer comment l’œuvre offre une lecture subversive des valeurs qui sous-tendent ces catégories structurelles du Paris industriel. Ce jeu des catégories fait de la Petite danseuse une œuvre instable et ambiguë à l’image, peut-être exacerbée, de la société. La sculpture de Degas joue avec et surtout entre ces divers pôles de la société parisienne, décloisonnant ceux-ci et proposant une autre façon de comprendre la société contemporaine. Prenant ancrage dans un discours critique postmoderne, féministe et postcolonialist, le présent travail se propose ainsi de réactualiser la fonction critique de l’œuvre.

Une esthétique hyperréaliste en littérature? : narrativité picturale et langage visuel dans l'œuvre romanesque de Suzanne Jacob (1991-2005)

Ce mémoire s'attarde à la notion d'hyperréalisme en littérature contemporaine et à son incarnation spécifique dans trois romans de Suzanne Jacob : L'Obéissance (1991), Rouge mère et fils (2001) et Fugueuses (2005). Le recours à la théorie et à l'histoire de la peinture est essentiel puisque l'hyperréalisme est d'abord endossé par l'art pictural. De plus, la peinture, la photographie, le cinéma, la musique, la télévision, la sculpture, l'architecture et la littérature sont autant de médiations fortement présentes dans le roman hyperréaliste. Cette présence multiple des médias est essentielle au caractère hyperréaliste d'une œuvre ; la tentative d'intégrer le réel passe par un détour représentationnel. Les manifestations stylistiques et narratives de l'hyperréalisme sont associées à l'intégration de formes empruntées à d'autres arts ou médias comme la fugue et le fait divers. Les effets de l'hyperréalisme sur la narration se manifestent également par un éclatement des focalisations, en témoignent la fragmentation narrative ainsi que l'importance accordée au détail. Enfin, l'hyperréalisme joue sur une tension constante entre continuité et rupture. Les conséquences sont à envisager dans une sorte d'appréhension du réel, tant par le personnage que par le roman, qui doivent composer avec une multiplicité de représentations.

Caractérisation clinique et génétique d’une famille canadienne-française atteinte de la neuropathie héréditaire sensitive avec rétinite pigmentaire et ataxie

La complexité de l’étude des neuropathies héréditaires provient de leur hétérogénéité clinique et génétique et de la diversité des fibres composant les nerfs périphériques. Cette complexité se reflète dans les nombreuses classifications différentes. Les neuropathies héréditaires se classifient entre autres selon leur mode de transmission et leur atteinte sensitive, autonomique et motrice. Les neuropathies héréditaires sensitives et autonomiques (NHSA) se présentent avec une perte de la sensation distale aux membres, accompagnée d’autres manifestations selon le type de NHSA. L’étude des NHSA est facilitée lorsqu’il existe des grappes de familles originaires de régions du Québec où des effets fondateurs pour des maladies récessives ont déjà été identifiés. Nous avons recruté une grande famille canadienne-française originaire de Paspébiac dans la Baie-des-Chaleurs dans laquelle nous avons identifié quatre cas atteints d’une neuropathie héréditaire sensitive avec rétinite pigmentaire et ataxie (NHSRPA). Nous avons émis l’hypothèse que nous étions en présence d’une nouvelle forme de neuropathie héréditaire sensitive récessive à effet fondateur. Afin d’identifier la position chromosomique du gène muté responsable de la NHSRPA, nous avons tout d’abord complété un criblage du génome en génotypant des marqueurs microsatellites «single tandem repeat» (STR) sur des individus clés et nous avons ensuite procédé à une analyse de liaison génétique paramétrique. Ces études nous ont permis de lier cette famille au chromosome 1 et de définir un premier intervalle candidat de 6,7 Mb. Grâce à un génotypage de marqueurs «single nucleotide polymorphism» (SNP), nous avons réduit l’intervalle candidat à 5,3 Mb au locus 1q32,2-q32,3. Cette région contient 44 gènes candidats. Une revue plus fine de la littérature a fait ressortir qu’une famille espagnole et une américaine de souche hollandaise souffrant de la même maladie avaient déjà été liées au même locus. L’origine possiblement basque de notre famille gaspésienne nous a poussé à comparer l’haplotype porteur avec celui de la famille espagnole qui, quoi que gitane, provient du pays basque espagnol. Ces travaux ont démontré le partage d’une région de 203 kb. Afin de rétrécir davantage notre intervalle candidat, nous avons comparé les haplotypes des cas entre les deux familles et nous avons identifié un dernier intervalle candidat de 60 SNP au locus 1q32,3. Cette région ne contient que quatre gènes candidats dont le plus intéressant est le gène «activating transcription factor» (ATF3). À ce jour, aucune mutation n’a été trouvée dans le gène ATF3 et les gènes FAM71A, BATF3 et NSL1. Des expériences supplémentaires sont nécessaires afin d’identifier le gène muté responsable de la NHSRPA.

Symbolique florale dans le tableau de Jean-Baptiste Belin de Fontenay Vase d’or, fleurs et buste de Louis XIV (1687)

Le tableau de Jean-Baptiste Belin de Fontenay intitulé Vase d’or, fleurs et buste de Louis XIV est le morceau de réception que le peintre a présenté à l’Académie royale de peinture et de sculpture en 1687. Malheureusement peu étudié, ce tableau n’en comporte pas moins trois problématiques très intéressantes. Tout d’abord, il rassemble trois genres de peinture dans une seule composition : la nature morte, le portrait et la peinture d’histoire, illustrés respectivement par les fleurs, le buste du roi et la pièce d’armure. L’association de ces trois genres dans un tableau de nature morte est peu commune dans la peinture française du 17e siècle. Il est donc nécessaire de vérifier s’il existe un lien entre les fleurs, l’image de Louis XIV et l’armure. Ensuite, le contraste entre la polychromie des fleurs et la monochromie de la sculpture et de l’ameublement est frappante ; il est possible de lier ce contraste au phénomène des débats entre le dessin et la couleur de l’Académie royale de peinture et de sculpture à la deuxième moitié du 17e siècle. D’ailleurs, les fleurs, qui n’étaient pas le sujet central dans le programme original de Le Brun, deviennent le sujet principal du tableau et occupent une place plus importante que le buste de Louis XIV. Cette modification n’a cependant pas choqué les juges de l’Académie puisque la toile a été acceptée sans contestation. Elle amène donc à s’interroger sur la hiérarchie des genres de peinture qui est la doctrine officielle de l’Académie royale de peinture et de sculpture de l’époque. Le noyau de la recherche consiste à vérifier si les fleurs n’occupent qu’une simple fonction décorative ou si elles peuvent être associées à des symboles. Notre recherche examine d’abord l’utilisation des symboles floraux dans la culture française du 17e siècle. Par la suite, elle étudie cette utilisation dans le domaine politique, à savoir que les fleurs pourraient être liées à la louange de Louis XIV. Enfin, elle analyse les domaines artistiques et esthétiques, c’est-à-dire la façon dont le tableau reflète, par l’utilisation des symboles floraux, l’évolution des théories de l’art, la hiérarchie des genres de peinture et les débats du dessin et de la couleur, en France, durant la deuxième moitié du 17e siècle.
