Achievements and future petspective for gene transfer from wild relatives to the cultivated species in cool season food legumes

The following cultivated crop species, chickpea (Cicer arietinum L.), lentil (Lens culinaris Medik.), pea (Pisum sativum L.) and faba bean (Visa faba L.) in the genera Cicer L., Lens Miller, Pisum L. and Vicia L., respectively; are main diet and calorie sources for human in most part of the world. Selection processes for higher yield and quality characteristics during domestication have resulted in narrowing of the genetic variation in the cultivated crop species of the cool season food legumes. Wild Cicer, Lens, Pisum and Vicia species do not consist of useful variation for morphological characteristics and protein content, but they also possess sources of resistance to biotic and abiotic stresses. The aims of the present study were to review (i) for resistance to abiotic and biotic stresses on wild species of Cicer, Lens, Pisum and Vicia; (ii) on achievements and future perspective for gene transfer from wild species to the cultivated species in cool season food legumes

Ratlarda Deneysel Omurilik Travmasında Karvedilol’ün İkincil Hasara Etkisi

Aim: Previous studies have shown that carvedilol has a neuroprotective effect in animal models of brain ischemia and brain oxidative damage in vitro. This study was perfomed to investigate the effect of carvedilol on the secondary damage in experimental spinal cord injury (SCI). Material and methods: Twenty-four Wistar albino rats were divided into three groups. Group 1 underwent laminectomy alone. Group 2 underwent laminectomy followed by SCI and received carvedilol. Group 3 underwent laminectomy followed by SCI and received no medication. The neurological functions were assessed by Tarlov’s motor scale at the first and 24th hours. Oxidative stress status was assessed by MDA, SOD, MPO, GSH activities. A TUNEL-based apoptosis kit was used for evaluating apoptosis in the spinal cord samples and hematoxylinand eosin-stained specimens were used for light microscopic examination. Results: Carvedilol reduced apoptosis and regulated oxidant and antioxidant status by increasing SOD and GSH levels and reducing MPO and MDA levels in the spinal tissue homogenate. Neurological examination of rats revealed statistically significant improvement 24 hours after the trauma. Conclusion: Carvedilol has a statistically significant therapeutic effect, especially on functional recovery, and we found that carvedilol reduced secondary damage by inhibiting apoptosis and regulating the oxidant and antioxidant status.Amaç: Beyinde oksidatif hasar ve iskemi ile ilgili daha önce yapılan in vitro hayvan modeli çalışmalarında karvedilolün nöron koruyucu etkilerinin olduğu gösterildi. Çalışmada karvedilolün deneysel spinal travma modelinde ikincil hasar üzerine olan etkileri araştırıldı. Yöntem ve Gereçler: 24 adet Wistar albino tipi sıçan üç gruba ayrıldı. Spinal kord yaralanması ağırlık düşürme modeli ile gerçekleştirildi. Birinci gruba sadece laminektomi uygulandı. İkinci gruba laminektomi yapılarak spinal kord yaralanması oluşturuldu ve karvedilol verildi. Üçüncü gruba laminektomi yapılıp spinal kord yaralanması oluşturuldu ve herhangi bir medikasyon uygulanmadı. Tüm gruplarda deneklerin birinci ve 24. saatlerde Tarlov motor skorlaması ile nörolojik muayeneleri kaydedildi. Oksidatif stres ölçümü için MDA (malonildialdehit), SOD (süperoksit dismutaz), MPO (myeloperoksidaz) ve GSH (glutatyon) aktiviteleri kullanıldı. Apoptozis düzeyini belirlemek için TUNEL kiti ve ışık mikroskobi bulguları için hematoksilen eozin boyası kullanıldı. Bulgular: Karvedilol apoptozis düzeyini azalttı ve SOD ile GSH düzeyini artırıp MPO ve MDA düzeylerini azaltarak oksidasyon ve antioksidasyon olaylarını düzenledi. Sonuç: Karvedilol özellikle fonksiyonel iyileşme üzerine istatistiksel olarak olumlu etki oluşturdu ve apoptozisi azaltıcı ve oksidasyon-antioksidasyon olaylarını olumlu yönde düzenleyici etki gösterdi

Spatial patterns and intraspecific diversity of the glacial relict legume species Vavilovia formosa (Stev.) Fed. in Eurasia

Vavilovia formosa is one of five genera in tribe Fabeae, (Fabaceae, Leguminosae) with close phylogenetic relationships to Pisum. It grows in subalpine and alpine levels in Armenia, Azerbaijan, Georgia, Iran, Iraq, Lebanon, Russia and Turkey and is recognized as an endangered and protected plant. This study was conducted to reveal its intraspecific variability, as well as to predict the past, extant and future species distribution range. We analysed 51 accessions with common phylogenetic markers (trnF-trnL, trnS-trnG, matK, rbcL, psbA-trnH and ITS). These represent in total up to 2551 bp of chloroplast and 664 bp of nuclear sequences per sample. Two populations from Turkey and Armenia were analysed for genetic diversity by AFLP

Legume Crops Phylogeny and Genetic Diversity for Science and Breeding

Economically, legumes (Fabaceae) represent the second most important family of crop plants after the grass family, Poaceae. Grain legumes account for 27% of world crop production and provide 33% of the dietary protein consumed by humans, while pasture and forage legumes provide vital part of animal feed. Fabaceae, the third largest family of flowering plants, has traditionally been divided into the following three subfamilies: Caesalpinioideae, Mimosoideae, and Papilionoideae, all together with 800 genera and 20,000 species. The latter subfamily contains most of the major cultivated food and feed crops. Among the grain legumes are some of mankind's earliest crop plants, whose domestication parallelled that of cereals: Soybean in China; faba bean, lentil, chickpea and pea in the Fertile Crescent of the Near East; cowpeas and bambara groundnut in Africa; soybean and mungbeans in East Asia; pigeonpea and the grams in South Asia; and common bean, lima bean, scarlet runner bean, tepary bean and lupin in Central and South America. The importance of legumes is evidenced by their high representation in ex situ germplasm collections, with more than 1,000,000 accessions worldwide. A detailed knowledge of the phylogenetic relationships of the Fabaceae is essential for understanding the origin and diversification of this economically and ecologically important family of angiosperms. This review aims to combine the phylogenetic and genetic diversity approaches to better illustrate the origin, domestication history and preserved germplasm of major legume crops from 13 genera of six tribes and to indicate further potential both for science and agriculture.</p

European guidelines on structure and qualification of general thoracic surgery

OBJECTIVE To update the recommendations for the structural characteristics of general thoracic surgery (GTS) in Europe in order to provide a document that can be used as a guide for harmonizing the general thoracic surgical practice in Europe. METHODS A task force was created to set the structural, procedural and qualification characteristics of a European GTS unit. These criteria were endorsed by the Executive Committee of the European Society of Thoracic Surgeons and by the Thoracic Domain of the European Association for Cardio-Thoracic Surgery and were validated by the European Board of Thoracic Surgery at European Union of Medical Specialists. RESULTS Criteria regarding definition and scope of GTS, structure and qualification of GTS unit, training and education and recommendations for subjects of particular interest (lung transplant, oesophageal surgery, minimally invasive thoracic surgery, quality surveillance) were developed. CONCLUSIONS This document will hopefully represent the first step of a process of revision of the modern thoracic surgeons' curricula, which need to be qualitatively rethought in the setting of the qualification process. The structural criteria highlighted in the present document are meant to help and tackle the challenge of cultural and language barriers as well as of widely varying national training programme

Tumours of the thymus: a cohort study of prognostic factors from the European Society of Thoracic Surgeons database

OBJECTIVES A retrospective database was developed by the European Society of Thoracic Surgeons, collecting patients submitted to surgery for thymic tumours to analyse clinico-pathological prognostic predictors. METHODS A total of 2151 incident cases from 35 institutions were collected from 1990 to 2010. Clinical-pathological characteristics were analysed, including age, gender, associated myasthenia gravis stage (Masaoka), World Health Organization histology, type of thymic tumour [thymoma, thymic carcinoma (TC), neuroendocrine thymic tumour (NETT)], type of resection (complete/incomplete), tumour size, adjuvant therapy and recurrence. Primary outcome was overall survival (OS); secondary outcomes were the proportion of incomplete resections, disease-free survival and the cumulative incidence of recurrence (CIR). RESULTS A total of 2030 patients were analysed for OS (1798 thymomas, 191 TCs and 41 NETTs). Ten-year OS was 0.73 (95% confidence interval 0.69-0.75). Complete resection (R0) was achieved in 88% of the patients. Ten-year CIR was 0.12 (0.10-0.15). Predictors of shorter OS were increased age (P < 0-001), stage [III vs I HR 2.66, 1.80-3.92; IV vs I hazard ratio (HR) 4.41, 2.67-7.26], TC (HR 2.39, 1.68-3.40) and NETT (HR 2.59, 1.35-4.99) vs thymomas and incomplete resection (HR 1.74, 1.18-2.57). Risk of recurrence increased with tumour size (P = 0.003), stage (III vs I HR 5.67, 2.80-11.45; IV vs I HR 13.08, 5.70-30.03) and NETT (HR 7.18, 3.48-14.82). Analysis using a propensity score indicates that the administration of adjuvant therapy was beneficial in increasing OS (HR 0.69, 0.49-0.97) in R0 resections. CONCLUSIONS Masaoka stages III-IV, incomplete resection and non-thymoma histology showed a significant impact in increasing recurrence and in worsening survival. The administration of adjuvant therapy after complete resection is associated with improved surviva

Predictors of attitudinal and behavioral outcomes in mobile advertising: A field experiment

The study examines consumer responses to SMS-based mobile advertising campaigns using a field experiment with actual behavioral responses. Specifically, the effects of message characteristics (i.e., incentives and prior permission) and individual differences of message recipients (i.e., content involvement, prior experience with the mobile medium, and medium-fit perceptions) on the attitudinal and behavioral outcomes of such campaigns are investigated. Perceived intrusiveness of the message and attitude toward the campaign are conceptualized as key attitudinal reactions triggered by a mobile advertising message, which in turn influence the behavioral responses generated by the campaign. Findings suggest that, in comparison to permission and incentive, individual differences are stronger determinants of responses to mobile advertising campaigns. Additionally, intriguing insights with respect to the effectiveness of different types of incentives are provided
