The World Cancer Research Fund and the American Institute for Cancer Research recommend a plant-based diet to cancer survivors, which may reduce chronic inflammation and excess adiposity associated with worse survival. We investigated associations of plant-based dietary patterns with inflammation biomarkers and body composition in the Pathways Study, in which 3659 women with breast cancer provided validated food frequency questionnaires approximately 2 months after diagnosis. We derived three plant-based diet indices: overall plant-based diet index (PDI), healthful plant-based diet index (hPDI) and unhealthful plant-based diet index (uPDI). We assayed circulating inflammation biomarkers related to systemic inflammation (high-sensitivity C-reactive protein [hsCRP]), pro-inflammatory cytokines (IL-1β, IL-6, IL-8, TNF-α) and anti-inflammatory cytokines (IL-4, IL-10, IL-13). We estimated areas (cm2) of muscle and visceral and subcutaneous adipose tissue (VAT and SAT) from computed tomography scans. Using multivariable linear regression, we calculated the differences in inflammation biomarkers and body composition for each index. Per 10-point increase for each index: hsCRP was significantly lower by 6·9 % (95 % CI 1·6%, 11·8%) for PDI and 9·0 % (95 % CI 4·9%, 12·8%) for hPDI but significantly higher by 5·4 % (95 % CI 0·5%, 10·5%) for uPDI, and VAT was significantly lower by 7·8 cm2 (95 % CI 2·0 cm2, 13·6 cm2) for PDI and 8·6 cm2 (95 % CI 4·1 cm2, 13·2 cm2) for hPDI but significantly higher by 6·2 cm2 (95 % CI 1·3 cm2, 11·1 cm2) for uPDI. No significant associations were observed for other inflammation biomarkers, muscle, or SAT. A plant-based diet, especially a healthful plant-based diet, may be associated with reduced inflammation and visceral adiposity among breast cancer survivors.
This chapter synthesizes current knowledge about the neuroscience of relationships. Although there are challenges to forming successful relationship, this chapter begins with the premise that humans, like other species, are wired to form, and benefit from, social connections. The chapter defines social neuroscience and discusses the research methods neuroscientists use. In recent decades social neuroscientists have begun contributing to a better understanding of the neurobiological substrates of close relationships (e.g., by unraveling their specific networks in the human brain). Early research focused on love including not only specifying what brain areas are recruited during a behavioral task, but also, specifying when and in what specific combinations they are activated. Social neuroscientists have also examined types of love and types of social rejection (e.g., loneliness as well as social and romantic rejection). The chapter concludes with current challenges facing social neuroscientists and directions their work could profitably pursue.
This collection of essays pays tribute to Nancy Freeman Regalado, a ground-breaking scholar in the field of medieval French literature whose research has always pushed beyond disciplinary boundaries. The articles in the volume reflect the depth and diversity of her scholarship, as well as her collaborations with literary critics, philologists, historians, art historians, musicologists, and vocalists - in France, England, and the United States. Inspired by her most recent work, these twenty-four essays are tied together by a single question, rich in ramifications: how does performance shape our understanding of medieval and pre-modern literature and culture, whether the nature of that performance is visual, linguistic, theatrical, musical, religious, didactic, socio-political, or editorial? The studies presented here invite us to look afresh at the interrelationship of audience, author, text, and artifact, to imagine new ways of conceptualizing the creation, transmission, and reception of medieval literature, music, and art.

Storage of intact Texas gourd [Cucurbita texana (A.) Gray] pepos for 21 days after harvest increased germination of seeds from pepos collected 15 to 47 days after flowering. Germination increased as day length decreased and as osmotic potential of germination media increased. Temperatures of 20, 25, and 30C resulted in 72, 93, and 99% germination, respectively. No seeds germinated at 10 or 40C. Seedling emergence decreased as planting depth increased, with no emergence from 12.5 cm. Control of Texas gourd in soybeans [Glycine max (L.) Merr.] was achieved with preemergence applications of metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)-one], metribuzin plus alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl)-acetanilide], and oxadiazon [2-tert-butyl-4 (2,4-dichloro-5-isopropoxyphenyl)-δ2-1,3,4-oxadiazolin-5-one], with successful control partially dependent on soil and climatological conditions. Postemergence treatments that resulted in adequate control included applications of acifluorfen {5-[2-chloro-4-(trifluoromethyl)-phenoxy]-2-nitrobenzoic acid}, oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl) benzene], and metribuzin plus 2,4-DB [4-(2,4-dichlorophenoxy)butyric acid] applied at an early soybean growth stage and repeated.
Acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} and bentazon [3-(1-methylethyl-(1H)-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide] plus acifluorfen were applied through hydraulic flat-fan nozzles or controlled-droplet applicators (CDA) in water plus surfactant, soybean [Glycine max (L.) Merr.] oil and water emulsions, and soybean oil alone. Except for inadequate weed control with CDA applications at 7 L/ha, method of application did not affect weed control of common cocklebur (Xanthium strumarium L. #3 XANST) or smooth pigweed (Amaranthus hybridus L. # AMACH) at high rates of bentazon plus acifluorfen (560 plus 280 g ai/ha or above). With low rates (280 plus 140 g/ha or less), hydraulic flat-fan nozzles were more effective than CDA applications. Early CDA applications of acifluorfen in an oil carrier at a volume of 9 L/ha were as effective as hydraulic nozzle applications at a carrier volume of 47 L/ha. Later applications resulted in inadequate weed control. Increasing soybean oil concentration from 2.5 to 40% (v/v) in acifluorfen spray mixtures did not significantly increase the phytotoxicity of acifluorfen.
Field experiments were conducted using a stale seedbed production system to determine the effect of herbicide application time on preplant, preplant incorporated (PPI), and at-planting treatments on weed control and soybean yield. Herbicides were applied on the surface preplant (PPL) or PPI at 6 to 7, 4 to 5, and 2 to 3 wk before planting and just prior to planting. The differences in weed control and soybean yield among years were due to rainfall patterns 2 wk after herbicide application and during the growing season. Preplant treatments applied 2 to 5 wk before planting generally controlled common cocklebur and pitted morningglory better than preplant treatments applied 6 to 7 wk before planting due to persistence of herbicide activity or treatments at planting due to a greater chance of obtaining adequate rainfall for herbicide activation, more uniform seedbed at planting, and larger weeds at application. Metribuzin plus chlorimuron was less suited than imazaquin as a preplant treatment when applied more than 2 weeks before planting.

Representations of storytellers and their performance within medieval narratives provide rich material for study. Particularly revealing in this regard is a subset of medieval narratives in which characters temporarily assume the identity of a professional storyteller. In such key moments, readers or listeners witness the process by which an actual, extradiegetic storyteller constructs the fictional figure of an intradiegetic storyteller. The tale of ‘Renart jongleur’ – branch Ib of the Roman de Renart – is one such narrative. This story, wherein Renart disguises himself as an inept Breton minstrel, shows us how the author constructs Renart's identity as a storyteller.
In ‘Renart jongleur’ (also sometimes referred to as ‘Renart teinturier’), Renart the fox paradoxically conceals his verbal prowess behind the mask of an incompetent minstrel whose unmasking reveals and affirms Renart's essential identity as a master narrator. The author structures the branch using a complex verbal game in which the power and authority of verbal expression continually passes from one character to another (from Noble to Isengrin, from Isengrin to Tibert, from Tibert to Poncet and so on) until the dénouement when Renart assumes the place of primary storyteller and asserts his verbal domination through exclusive possession of the power and pleasure that language confers. In telling his story, the medieval author of ‘Renart jongleur’ self-reflectively uses his own narrative to assert the ultimate power of storytelling and storytellers.
In the pages that follow, we first establish the essentially linguistic nature of the fox's disguise. We analyze how Renart conceals his powerful mastery of speech under the mask of an innocuous and inept minstrel. We then study the ironic inversion that propels the narrative, a reversal by which Renart, disguised as a professional storyteller, cedes verbal expression to others to become the auditor of stories of his own adventures. Renart yields the pleasure of storytelling and the power to direct the plot to other characters until he captures them in his verbal trap and reduces them to silence. The branch reaches its culmination when Renart is reborn as the narrator of his own story and regains mastery of both the narrative and the laughter that the narrative elicits.
The introduction of the ‘western diet’ marked a decline in omega–3 fatty acids rich foods and a concurrent increase in saturated and omega–6 fatty acids that persists today. Historically, circumpolar people have had a low incidence of obesity, diabetes and cardiovascular disease and this has been largely attributed to polyphenolic compounds and omega–3 fatty acids offered from subsistence foods. In this report, we studied sled dogs as an Arctic sentinel species for monitoring the effect of a changing diet on lipid profiles along the Yukon River. Subsistence fed village sled dogs along the Yukon River, maintained largely on salmon were compared with a control kennel maintained on commercial food. Profiles showed higher levels for long chain omega–3 fatty acids in village subsistence fed dogs compared to control dogs and an opposite trend for omega–6 fatty acids, establishing baseline levels for follow up studies. A comparison with data for previously published mercury levels from the same cohort of dogs revealed a positive correlation with alpha–linolenic fatty acid and a negative correlation with linoleic fatty acid. Food and nutritional security is a concern in the Arctic as the impacts of climate change and transport of contaminants become obvious. This study supports not only the nutritional value of a subsistence diet but also the utility of sled dogs as a sentinel for human dietary change.
The rising costs of healthcare and other social welfare programmes and the efforts of the federal, state and local governments to reduce services that are provided by governmental agencies have increased the importance of distinguishing personal and familial responsibilities from public (that is, governmental) obligations to dependent individuals. Societal debates about collective, familial and individual responsibility for dependent individuals are not new, but demographic and social changes have made the issue of who will assist dependent family members an increasingly important topic.
Increased longevity and reduced fertility in the past few decades have profoundly affected the structure of families in the US. Just as in other industrialised nations, life expectancies in the US have been increasing (Vaupel and Kistowski, 2005), which has resulted in more multiple-generation extended families than ever before (Uhlenberg and Kirby, 1998). These multiple-generation families are different than in the distant past, however, because lowered fertility means that there are fewer younger family members to care for greater numbers of older people than was true just a couple of generations ago. Younger adults are therefore likely to have more older kin who potentially need aid, which has fuelled societal concerns about the well-being of older adults.
Unlike many other industrialised nations, the US lacks a comprehensive system of government-sponsored social programmes for its citizens. Although there are a few federal support programmes for older adults (that is, Medicare, which provides funds for health-related needs), and even fewer state programmes that are primarily for low-income older people, for the most part responsibilities for the care and support of older adults have been seen in the US as belonging primarily to families.
The belief that families are obligated to care and support older kin is so widespread that 30 of the 50 states have filial responsibility laws that define which family members are obligated to provide care and what care they are obligated to provide (Bulcroft et al, 1989). Critics have argued that these laws and other US social policies about intergenerational care and assistance are based on the outdated and questionable assumptions that kin networks are unwaveringly emotionally close and loving, families have readily available members to assist older kin and family membership is stable (Hooyman and Gonyea, 1995). These assumptions do not reflect the experiences of many, if not most, families in the 21st century.
In the midnight quiet of June 8, 2004, in her French Department office at New York University, Nancy Freeman Regalado and I celebrated her sixty-ninth birthday by sealing a Federal Express box containing the manuscript for Performing Medieval Narrative, the volume we had edited with Evelyn (Timmie) Birge Vitz. Fortified by Nancy's favorite fig cookies, we wrapped up years of work on our book dedicated to the performance of medieval stories. Work on this volume made me more keenly aware than ever before of the centrality of performance and the performer in medieval French culture.
In this essay I examine how authors construct and define the most pivotal figure in that performance culture: the minstrel. I focus particularly on the latetwelfth-century anonymous Folie Tristan of Oxford and the “Tristan ménestrel” episode in Gerbert de Montreuil's Continuation de Perceval from 1226–30. In both of these verse narratives an exiled Tristan disguises himself as a minstrel in order to enter Marc's court and visit his beloved, Yseut. In the Folie, Tristan adopts the mask of a minstrel-fool and travels alone to Tintagel. There he amuses Marc's court with a mixture of true and fictive stories in which he claims to be not Tristan, but Tantris, the minstrel-harpist as whom Tristan masquerades in other medieval narratives. In the Continuation, Tristan recruits Gauvain and twelve other knights of Arthur's Round Table to join him in minstrel disguise. Together they travel to Lancïen and present themselves as minstrel-watchmen to Marc's court where, still masked as minstrels, they fight on the king's behalf in his tournament against the Roi des Cent Chevaliers. Both Gerbert and the author of the Folie use the terms menestrel and jogleor or jugleres to refer to Tristan (and his companions) in disguise, yet their concepts of the minstrel differ remarkably.
The disguise passages in the two narratives reveal how different authors create the same character, Tristan, and how they define the minstrel disguises he assumes. In addition, the Folie demonstrates how one author constructs two different minstrel disguises – those of the minstrel-fool and the minstrel-harpist – in a single narrative. Analysis of the signs authors use to create Tristan's minstrel masks shows the complexity and flexibility of authorial notions of the medieval minstrel, and more generally of character.
