Heirloom and Hybrid Corn in the American Corn Belt: an Ethnography of Seed Saving Practices

This ethnographic study examines the practices and context of contemporary heirloom corn seed saving practices and projects in the American Corn Belt. It examines heirloom corn conservation and hand pollination practices at Seed Savers Exchange in Decorah, Iowa in 2015. From there the study extends to interviews with heirloom farmers, breeders and gardeners in Wisconsin and Illinois. The findings indicate that the lines between the mainstream and the margins of corn production are highly blurred, and that there is a considerable amount of cross-pollination of ideas and practices between alternative corn farming and dominant industrial hybrid production in the American Corn Belt as they exist in proximity and utilize similar public spaces and resources. The results of these cross-pollinations of ideas are differing visions of sustainability that farmers, breeders and seed savers use to frame their heirloom corn growing projects and maintain the marginal spaces required for them to grow in the Corn Belt. The author explores the histories of hybrids and heirlooms in the Corn Belt and the contemporary evolution of USDA Organic Corn Production to illustrate this point

Intuitive scrolling for feed-based applications

This disclosure describes techniques to perform adaptive scrolling based on input gestures provided by a user. Input provided by the user is categorized as scroll, small fling, or big fling. The categorization is based on device-independent velocity thresholds. When the input is classified as scroll, e.g., a slow swipe gesture, a feed interface that scrolls over items is provided. When the input is classified as a small fling, the item list snaps to the item that is adjacent to a current item in the view, determined based on the direction of the swipe. When the input is classified as a big fling, the item list scrolls and skips items based on the gesture and snaps to the item that is nearest to the location where the scroll concludes, as determined based on the input. Such adaptive behavior that combines natural scrolling with snapping behavior improves recall and allows users to focus on each content item and provides a flexible browsing mechanism

Can Vitex Agnus Castus be Used for the Treatment of Mastalgia? What is the Current Evidence?

There have been many treatments suggested for the management of mastalgia; one of these is the fruit extract of Vitex Agnus castus L. commonly known as Agnus castus, an extract of a deciduous shrub native to Mediterranean Europe and Central Asia. It is postulated that A. castus suppresses the stress-induced latent hyperprolactinemia which is a release of supra-physiological levels of prolactin in some patients in response to stressful stimuli. It is postulated that A. castus could be effective in the treatment of cyclical mastalgia by inhibiting the release of excess prolactin by blocking Dopamine-2 receptor type on pituitary. The adverse events following A. castus treatment are mild and reversible. The aim of this review is assess the efficacy of A. castus in the treatment of mastalgia. Data from randomized and non-randomized studies regarding the efficacy and safety of A. castus is reviewed in a systematic fashion. It is concluded that A. castus can be considered as an efficient alternative phytotherapeutic agent in the treatment of mastalgia

Persistent contaminants and herpesvirus OtHV1 are positively associated with cancer in wild California Sea Lions (Zalophus californianus)

This work was funded by the Geoffrey Hughes Fellowship, the National Institutes of Health (Fogarty International Center) and National Science Foundation joint program for the Ecology of Infectious Disease, the National Marine Fisheries Service Marine Mammal Heath and Stranding Program, and the Natural Environment Research Council grant number NE/R015007/.The prevalence of cancer in wild California sea lions (Zalophus californianus) is one of the highest amongst mammals, with 18–23% of adult animals examined post-mortem over the past 40 years having urogenital carcinoma. To date, organochlorines, genotype and infection with Otarine herpesvirus-1 (OtHV-1) have been identified in separate studies using distinct animals as associated with this carcinoma. Multi-year studies using large sample sizes to investigate the relative importance of multiple factors on marine mammal health are rare due to logistical and ethical challenges. The objective of this study was to use a case control approach with samples from 394 animals collected over 20 years in a multifactorial analysis to explore the relative importance of distinct factors identified to date as associated with sea lion cancer in the likelihood of sea lion carcinoma. Stepwise regression indicated that the best model to explain carcinoma occurrence included herpesvirus status, contaminant exposure, and blubber depth, but not genotype at a single microsatellite locus, PV11. The odds of carcinoma was 43.57 times higher in sea lions infected with OtHV-1 (95% CI 14.61, 129.96, p <0.001), and 1.48 times higher for every unit increase in the loge[contaminant concentrations], ng g–1 (an approximate tripling of concentration), in their blubber (95% CI 1.11, 1.97, p <0.007), after controlling for the effect of blubber depth. These findings demonstrate the importance of contaminant exposure combined with OtHV1 infection, in the potential for cancer occurrence in wild sea lions.Publisher PDFPeer reviewe

Management and outcome of colorectal cancer during pregnancy: report of 41 cases

BACKGROUND: Colorectal cancer in pregnancy is rare, with an incidence of 0.8 per 100,000 pregnancies. Advanced disease (stage III or IV) is diagnosed more frequently in pregnant patients. We aimed to review all cases of colorectal cancer in pregnancy from the International Network on Cancer, Infertility and Pregnancy database in order to learn more about this rare disease and improve its management. METHODS: Data on the demographic features, symptoms, histopathology, diagnostic and therapeutic interventions and outcomes (obstetric, neonatal and maternal) were analysed. RESULTS: Twenty-seven colon and 14 rectal cancer cases were identified. Advanced disease was present in 30 patients (73.2%). During pregnancy, 21 patients (51.2%) received surgery and 12 patients (29.3%) received chemotherapy. Thirty-three patients (80.5%) delivered live babies: 21 by caesarean section and 12 vaginally. Prematurity rate was high (78.8%). Eight babies were small for gestational age (27.6%). Three patients (10.7%) developed recurrence of disease. Overall 2-year survival was 64.4%. CONCLUSION: Despite a more frequent presentation with advanced disease, colorectal cancer has a similar prognosis in pregnancy when compared with the general population. Diagnostic interventions and treatment should not be delayed due to the pregnancy but a balance between maternal and foetal wellbeing must always be kept in mind. ispartof: ACTA CHIRURGICA BELGICA vol:119 issue:3 pages:166-175 ispartof: location:England status: publishe

Gynecologic cancers in pregnancy: guidelines based on a third international consensus meeting

We aimed to provide comprehensive protocols and promote effective management of pregnant women with gynecological cancers. New insights and more experience have been gained since the previous guidelines were published in 2014. Members of the International Network on Cancer, Infertility and Pregnancy (INCIP), in collaboration with other international experts, reviewed existing literature on their respective areas of expertise. Summaries were subsequently merged into a manuscript that served as a basis for discussion during the consensus meeting. Treatment of gynecological cancers during pregnancy is attainable if management is achieved by collaboration of a multidisciplinary team of health care providers. This allows further optimization of maternal treatment, while considering fetal development and providing psychological support and long-term follow-up of the infants. Nonionizing imaging procedures are preferred diagnostic procedures, but limited ionizing imaging methods can be allowed if indispensable for treatment plans. In contrast to other cancers, standard surgery for gynecological cancers often needs to be adapted according to cancer type and gestational age. Most standard regimens of chemotherapy can be administered after 14 weeks gestational age but are not recommended beyond 35 weeks. C-section is recommended for most cervical and vulvar cancers, whereas vaginal delivery is allowed in most ovarian cancers. Breast-feeding should be avoided with ongoing chemotherapeutic, endocrine or targeted treatment. More studies that focus on the long-term toxic effects of gynecologic cancer treatments are needed to provide a full understanding of their fetal impact. In particular, data on targeted therapies that are becoming standard of care in certain gynecological malignancies is still limited. Furthermore, more studies aimed at the definition of the exact prognosis of patients after antenatal cancer treatment are warranted. Participation in existing registries (www.cancerinpregnancy.org) and the creation of national tumor boards with multidisciplinary teams of care providers (supplementary Box S1, available at Annals of Oncology online) is encouraged

European Society of Gynecological Oncology Statement on Fibroid and Uterine Morcellation

Recently, there has been an intense discussion about the issue of fibroid and uterine morcellation in relation to the risk of unrecognized uterine sarcoma spread. Morcellation can negatively influence the prognosis of patients, and transecting the specimen into pieces prevents the pathologist from performing proper disease staging. Many societies have published their statements regarding this issue. The European Society for Gynecological Oncology has established a working group of clinicians involved in diagnostics and treatment of oncogynecological patients to provide a statement from the oncological point of view. Leiomyosarcomas and undifferentiated endometrial sarcomas have generally dismal prognosis, whereas low-grade endometrial stromal sarcomas and adenosarcomas have variable prognosis based on their stage. A focus on the detection of patients at risk of having a sarcoma should be mandatory before every surgery where morcellation is planned by evaluation of risk factors (African American descent, previous pelvic irradiation, use of tamoxifen, rapid lesion growth particularly in postmenopausal patients) and exclusion of patients with any suspicious ultrasonographic signs. Preoperative endometrial biopsy should be mandatory, although the sensitivity to detect sarcomas is low. An indication for myomectomy should be used only in patients with pregnancy plans; otherwise en bloc hysterectomy is preferred in both symptomatic and postmenopausal patients. Eliminating the technique of morcellation could lead to an increased morbidity in low-risk patients; therefore, after thorough preoperative evaluation and discussion with patients, morcellation still has its place in the armamentarium of gynecologic surgery
