Glyphosate Residues in Soil and Air: An Integrated Review

Glyphosate [N-(phosphonomethyl) glycine] (GPS) is currently the most commonly applied herbicide worldwide. Given the widespread use of glyphosate, the investigation of the relationship between glyphosate and soil ecosystem is critical and has great significance for its valid application and environmental safety evaluation. However, although the occurrence of glyphosate residues in surface and groundwater is rather well documented, only few information are available for soils and even fewer for air. Due to this, the importance of developing methods that are effective and fast to determine and quantify glyphosate and its major degradation product, aminomethylphosphonic acid (AMPA), is emphasized. Based on its structure, the determination of this pesticide using a simple analytical method remains a challenge, a fact known as the “glyphosate paradox.” In this chapter a critical review of the existing literature and data comparison studies regarding the occurrence and the development of analytical methods for the determination of pesticide glyphosate in soil and air is performed

Flow Cytometry as a Diagnostic Tool in the Early Diagnosis of Aggressive Lymphomas Mimicking Life-Threatening Infection

Aggressive lymphomas can present with symptoms mimicking life-threatening infection. Flow cytometry (FC) is usually recommended for the classification and staging of lymphomas in patients with organomegaly and atypical cells in effusions and blood, after the exclusion of other possible diagnoses. FC may also have a place in the initial diagnostic investigation of aggressive lymphoma. Three cases are presented here of highly aggressive lymphomas in young adults, which presented with the clinical picture of fever of unknown origin (FUO) in patients severely ill. All followed a life-threatening clinical course, and two developed the hemophagocytic syndrome (HPS), but microbiological, immunological, and morphological evaluation and immunohistochemistry (IHC) failed to substantiate an early diagnosis. FC was the technique that provided conclusive diagnostic evidence of lymphoma, subsequently verified by IHC. Our experience with these three cases highlights the potential role of FC as an adjunct methodology in the initial assessment of possible highly aggressive lymphoma presenting with the signs and symptoms of life-threatening infection, although the definitive diagnosis should be established by biopsy. In such cases, FC can contribute to the diagnosis of lymphoma, independently of the presence of HPS

Patterns of Exile in Greek Tragedy

314 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1997.The argument that underlies the present study is that exile, defined as the exclusion from the social, religious and political life in the polis, constitutes in the tragic plays an exploration of civic identity by means of its opposite, reinforcing its importance through its very antithesis. This ideological view of tragic exile is supported by the plays examined which are organized around the following patterns: (1) Tragedies which draw on the topos of Athens as protector of exiles and refugees (A. Eu.; S. OC; E. Heracl.). These plays focus on the significance of belonging to the Athenian polis by presenting Athens as the only city which protects and receives the foreigner-exile by virtue of its democratic institutions. (2) Tragedies of nostos, set in Thebes or Argos, dramatize the return of a character to his native polis. In these plays, the homecoming is regularly followed by an act of vengeance which leads to kin-killing and results either in the returning character's death (e.g. A. A., Se.; E. Phoen.) or in a second exile (e.g. A. Ch.; E. Ba., El., HF). The plot pattern of nostos ending in exclusion points concretely to the investigation of identity which is analyzed in its primary determinants, namely, oikos and polis. The failure of nostos is emblematic of the dissolution of oikos and polis identity which can only be remedied in certain cases through integration in another polis (e.g. A. Eu.; E. HF). My project, in general, has even further implications; the condition of male and female exiles is different. But, even in the case of women the circumstances of their exile lead directly to the concept of women's civic identity which is circumscribed through marriage. Tragic tales of women wanderers and exiles can lead to a fruitful investigation of their civic identity through the representation of the antithetical connections between exile (absence from home, an undesirable state of affairs for women) and marriage, the means of return and reintegration for women exiles (e.g. A. Su.; E. Hel., IT, Me.).U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
