Pathogenicity in Verticillium on strawberry plants

In the most common strawberry cv. ’Elsanta’, Verticillium infection can lead to rapid wilt and even death of plants. It is known, that a dead plant can be located directly beside vital ones. In a survey of 8 fields in Brandenburg, Mecklenburg- Vorpommern, Sachsen-Anhalt and Sachsen, 432 genotypes of Verticillium dahliae Kleb. were isolated from wilted and even vital plants from 8 fields and classified by PCR-fingerprints. For strawberries, the genotypes can be classified as apathogenic, weakly and highly pathogenic according to the results of climate chamber experiments on strawberry transplants. At landscape scale, similarity analysis of the PCR fingerprints of 432 genotypes resulted in 13 genetic subtypes. Several of these subtypes occurred at all fields, whereas 1 subtype was found in one location only. At field scale, 2 to 11 different subtypes per field were observed. Vital plants were colonised by up to 9 subtypes, wilted plants by up to 11 subtypes. Population structure of Verticillium subtypes is different between vital and wilted plants, the same subtypes can occur in either plant group. In our plot experiments, wilt symptoms could be reduced by changing the Verticillium population structure in the plant. Inoculation of plants with a mixture of three Verticillium genotypes sustained plant vitality over a period of 15 months (WO 2007/051654)

Geese and Gauls – the Capitol in the Social Memory of the ‘Gallic Disaster’

This paper examines some aspects of the ‘Gallic Disaster’ in Roman memory culture, especially the role of the capitol. The capitol as a symbol of Roman resistance against foreign enemies and her dominance over the Mediterranean is the result of a longer development of cultural traditions and included a stylization after Greek accounts of the Persian capture of Athens. It can be shown that the sight of the Capitol stimulated the invention of different versions of the course of events during the siege, the use of historical exempla in speeches, and the development of ritual processions. As a result, the capitol was integrated in the memorial landscape of the city, and the ‘Gallic disaster’ was remembered as an important part of the history of the religious and political center of Rom

Systemic Amyloidosis due to Low-Grade Lymphoma

Lymphoma-related amyloidosis is a rare entity. Systemic AL amyloidosis is generally caused by an underlying plasma cell clone in the bone marrow with an intact monoclonal immunoglobulin G (IgG) or IgA protein. The rarity of the lymphoma-related amyloidosis makes the generation of data in randomized trials and the determination of the optimal treatment almost impossible. Therefore, treatment recommendations discussed here are based on either retrospective or small prospective trials of single centers

Metastatic Breast Cancer or Multiple Myeloma? Camouflage by Lytic Lesions

We report a case of a female with stage I infiltrating ductal carcinoma who received adjuvant therapy including trastuzumab. One year later she developed lytic lesions and was retreated with trastuzumab that was held after she developed symptomatic heart failure. Lytic lesions were attributed to relapse of breast cancer, and cardiac failure attributed to prior trastuzumab therapy. After complications necessitated multiple hospitalizations, a further workup revealed that the lytic lesions were not metastatic breast cancer but multiple myeloma. Her advanced multiple myeloma was associated with systemic amyloidosis involving gut and heart, which ultimately led to her demise. This report addresses the pitfalls of overlapping symptoms and the question of which patients with suspected metastatic disease should undergo a biopsy

Impact of chars and readily available carbon on soil microbial respiration and microbial community composition in a dynamic incubation experiment

The carbonisation of biomass and organic residues is discussed as an opportunity to store stabilised carbon compounds in soil and to reduce mineralisation and the emission of CO2. In this study, pyrolysis char (600 °C, 30 min) and hydrothermal carbonisation char (HTC char; 210 °C, 23 bar, 8 h), both derived from maize silage, were investigated in a short-term incubation experiment of soil mixtures with or without readily available carbon (glucose) in order to reveal impacts on soil microbial respiration and community composition. In contrast to pyrolysis char, the addition of HTC char increased respiration and enhanced the growth of fungi. The addition of glucose to soil-char mixtures containing either pyrolysis or HTC char induced an additional increase of respiration, but was 35% and 39% lower compared to soil-glucose mixtures, respectively, providing evidence for a negative priming effect. No significant difference was observed comparing the soil mixtures containing pyrolysis char + glucose and HTC char + glucose. The addition of glucose stimulated the growth of most microbial taxa under study, especially of Actinobacteria at the expense of fungi. Adding pyrolysis or HTC char to soil induced a decline of all microbial taxa but did not modify the microbial community structure significantly. Addition of pyrolysis or HTC char in combination with glucose however, increased the abundance of Actinobacteria and reduced the relative abundance of Acidobacteria and Betaproteobacteria while fungi were further increased in case of HTC char. We conclude that both chars hold the potential to bring about specific impacts on soil microbial activities and microbial community structure, and that they may compensate the variations induced by the addition of readily available carbon

Contraception in Adolescents

The age of adolescence is the time when most adolescents in the world begin to be sexually active with resultant millions of pregnancies and sexually transmitted diseases (STDs). This chapter considers methods of contraception for these adolescents, including oral contraceptives, transdermal contraception, minipills, intra-vaginal ring, injectable contraception, intrauterine devices (IUDs), barrier contraceptives, implants, and others. It is important for clinicians caring for sexually active youth to provide information regarding contraception and appropriate contraceptive prescriptions

Pre- and Post-Harvest Infection of Pasteurized Pickles with Fungi and Their Pectinolytic Potential to Soften the Product

Fungi and their enzymes have long been thought to cause the softening of pasteurized gherkins; however, the exact fungal species and timing of contamination are unknown. Ready-to-sell pickle jars and blossoms of growing gherkins were inoculated with DNA-sequenced fungi isolated from rotting gherkins to cause softening at various stages of production. Ready-to-sell gherkins inoculated with Fusarium oxysporum, Fusarium equiseti, Galactomyces geotrichum, Mucor circinelloides, Mucor hiemalis, Mucor fragilis, Plectosphaerella cucumerina, Alternaria sp., and Cladosporium sp. indicated a measurable texture reduction after pasteurization and 6 months of storage at room temperature. No texture changes were observed in gherkins infected during the growth phase. The fungi M. hiemalis, M. fragilis, and G. geotrichum tolerated the acidic-saline (approx. pH 4) environment in the jar for several days, thus the pectinolytic enzymes of these candidates were tested for heat and pH resistance. Although the measured endo-Polygalacturonase (PG) of M. fragilis had its optimum activity at pH < 4, all fungal enzymes were inactivated within 3 min at 80 °C corresponding to the pasteurization heat. Our study shows that conventionally occurring fungi and their enzymes have the potential to induce softening in pickles. Softening by these fungi is unlikely due to post- or pre-harvest contamination without any other influences.European agricultural fund for rural development (EAFRD)Peer Reviewe
