Carrot-Induced Systemic Reaction: A Unique Presentation of Pollen-Food Allergy Syndrome in a Young Boy.

Pollen-food allergy syndrome (PFAS) is a common IgE-mediated allergic condition resulting from cross-reactions between pollen and plant food allergens, primarily those in the PR-10 subfamily. Mostly symptoms are limited to the mouth and throat causing oral allergy syndrome (OAS). Systemic reactions are extremely rare.

Comparative Analysis of Symptomatology in Hospitalized Children with RSV, COVID-19, and Influenza Infections.

BACKGROUND The clinical course of respiratory syncytial virus (RSV), SARS-CoV-2, and influenza infections comprises many non-specific symptoms, which makes diagnosis difficult. The aim of this study was to retrospectively analyze the symptomatology of these infections in children and to search for correlations between them. MATERIAL AND METHODS A total of 121 children with a positive RSV (n=61), influenza (n=31), or SARS-CoV-2 (n=29) antigen test were enrolled in this retrospective analysis.

Biodegradation of the high explosive hexanitrohexaazaiso-wurtzitane (CL-20).

The aerobic biodegradability of the high explosive CL-20 by activated sludge and the white rot fungus Phanerochaete chrysosporium has been investigated. Although activated sludge is not effective in degrading CL-20 directly, it can mineralize the alkaline hydrolysis products. Phanerochaete chrysosporium degrades CL-20 in the presence of supplementary carbon and nitrogen sources.

Biodegradation kinetics of the nitramine explosive CL-20 in soil and microbial cultures.

The cyclic nitramine explosive CL-20 (C(6)H(6)N(12)O(12), 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12 -hexaazaisowurtzitane) is a relatively new energetic compound which could be a persistent organic pollutant. To follow its biodegradation dynamics, CL-20 was added to soil alone or together with organic co-substrates and N-source and incubated under oxic and anoxic conditions. Without co-substrates, the CL-20 degradation was detectable only under anoxic conditions.

The assessment of the energetic compound 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-Hexaazaisowurtzitane (CL-20) degradability in soil.

CL-20 is a relatively new energetic compound with applications in explosive and propellant formulations. Currently, information about the fate of CL-20 in ecological systems is scarce. The aim of this study is to evaluate the biodegradability of CL-20 in soil environments.
