Necrotic and chlorotic symptoms induced during Pyrenophora teres infection in barley leaves indicate a compatible interaction that allows the hemi-biotrophic fungus Pyrenophora teres to colonise the host. However, it is unexplored how this fungus affects the physiological responses of resistant and susceptible cultivars during infection. To assess the degree of resistance in four different cultivars, we quantified visible symptoms and fungal DNA and performed expression analyses of genes involved in plant defence and ROS scavenging.

Field phenotyping of crops has recently gained considerable attention leading to the development of new protocols for recording plant traits of interest. Phenotyping in field conditions can be performed by various cameras, sensors, and imaging platforms. In this chapter, practical aspects as well as advantages and disadvantages of aboveground phenotyping platforms are highlighted with a focus on drone-based imaging and relevant image analysis for field conditions.

The foliar microbiome can extend the host plant phenotype by expanding its genomic and metabolic capabilities. Despite increasing recognition of the importance of the foliar microbiome for plant fitness, stress physiology, and yield, the diversity, function, and contribution of foliar microbiomes to plant phenotypic traits remain largely elusive. The recent adoption of high-throughput technologies is helping to unravel the diversityand spatiotemporal dynamics of foliar microbiomes, but we have yet to resolve their functional importance for plant growth, development, and ecology.

Increasing agricultural losses due to biotic and abiotic stresses caused by climate change challenge food security worldwide. A promising strategy to sustain crop productivity under conditions of limited water availability is the use of plant growth promoting rhizobacteria (PGPR). Here, the effects of spore forming (FMCH001) on growth and physiology of maize ( L.

Veterinary Services (VS) as defined by the World Organisation for Animal Health (OIE) are institutions that can have varied structures, from the centralised to the completely decentralised, with ranges in between these two extremes. The VS include a broad range of public and civil society organisations and actors whose shared purpose is to deliver animal health services, and the interactions of these actors are governed by a range of formal and informal rules. The range of essential services to be carried out by the VS is laid out in the OIE Terrestrial Animal Health Code, which also provides certain key definitions.

Objective: To study the association between microalbuminuria and development of preeclampsia and preterm delivery in pregnant women with type 1 diabetes.

Research Design And Methods: This was a population-based prospective study in 846 normoalbuminuric or microalbuminuric women with type 1 diabetes without antihypertensive treatment in early pregnancy. Data were collected prospectively by one to three caregivers in each center and reported to a central registry.

Simulation exercises are considered a very valuable tool for testing contingency plans established for the control and eradication of rapid spreading animal diseases such as foot and mouth disease, classical swine fever and avian influenza. An inter-Nordic simulation exercise was conducted in 2005 with the objective of testing the national foot and mouth disease contingency plans adopted respectively by Denmark, Finland, Iceland, Norway and Sweden. The Central Veterinary Administrations of the five countries jointly prepared a scenario which involved about 40 livestock holdings, 4 reindeer flocks, 6 slaughterhouses and approximately 500 people.

Objective: To study the association between peri-conceptional A1C and serious adverse pregnancy outcome (congenital malformations and perinatal mortality).

Research Design And Methods: Prospective data were collected in 933 singleton pregnancies complicated by type 1 diabetes.

Results: The risk of serious adverse outcome at different A1C levels was compared with the background population.

Outbreaks of infectious animal diseases such as foot-and-mouth disease, classical swine fever, Newcastle disease and avian influenza may have a devastating impact, not only on the livestock sector and the rural community in the directly affected areas, but also beyond agriculture and nation wide. The risk of introducing disease pathogens into a country and the spread of the agent within a country depends on a number of factors including import controls, movement of animals and animal products and the biosecurity applied by livestock producers. An adequate contingency plan is an important instrument in the preparation for and the handling of an epidemic.

Large-scale outbreaks of animal disease cause mass death of animals, a devastating economic impact on livestock industries and communities and furthermore often great distress for owners and keepers of animals. Such large-scale outbreaks have, during the last decade, been experienced by certain EU Member States in pigs caused by classical swine fever outbreaks, in ruminants and pigs due to foot and mouth disease and in poultry as a result of infections by avian influenza virus. With the aim of preventing introduction of the OIE former list A diseases and enhance disease preparedness most European countries have in recent years adopted contingency plans and conducted simulation exercises.

Background: Few prenatal risk factors of prolonged pregnancy, a pregnancy of 42 weeks or more, are known. The objective was to examine whether sociodemographic, reproductive, toxicologic, or medical health conditions were associated with the risk of prolonged pregnancy.

Methods: Data from the Danish Birth Cohort in Denmark were used.

Background: In this prospective epidemiologic cohort study the aim was to identify possible risk factors for developing four different syndromes of pelvic girdle pain during pregnancy.

Methods: Over a one-year period a total of 2,269 consecutive pregnant women -- at week 33 of gestation -- responded to a structured questionnaire and underwent a thorough physical examination. Women who at baseline reported daily pain from pelvic joints and had corresponding objective findings were allocated, according to symptoms, into one of four classification groups, and followed up with questionnaires and physical examinations up to two years after delivery.

Objective: To analyze the association between bacterial vaginosis (BV) in early pregnancy and preterm birth, low birth weight (LBW) and small for gestational age (SGA) in a Danish population.

Methods: A geographically defined population-based prospective study of Danish-speaking pregnant women over18 years of age enrolled before week 24 and followed until delivery. BV was diagnosed by Amsel's clinical criteria at enrolment.

Background: Periodontitis shares several clinical and pathogenic characteristics with chronic arthritis, and there is some degree of coexistence. The aims of this study were to elucidate whether patients with localized aggressive periodontitis (LAgP), generalized aggressive periodontitis (GAgP), juvenile idiopathic arthritis (JIA), and rheumatoid arthritis (RA) share periodontal and hematological characteristics distinguishing them from individuals free of diseases.

The JP2 clone of Actinobacillus actinomycetemcomitans, a high-leukotoxin-producing strain, characterized by a 530-basepair (bp) deletion in the promoter region of the leukotoxin gene operon and mainly found among individuals with African origin, is associated with localized aggressive periodontitis. The objective of the study was to examine the occurrence of periodontal disease in a Moroccan immigrant family living in Denmark in which the oldest son (14 year) was referred and treated for localized aggressive periodontitis. Further, the potential occurrence of the JP2 clone of A.
