Desiccation in Conifer Leaves: Anatomical Changes and Determination of the Lethal Level

Botanical Gazette, 1952
1. The gradual drying of excised leaves of Austrian and white pine (Pinus nigra Arn., var. austriaca Asch. et Gr. and P. strobus L., respectively) is accompanied by marked shrinkage of cells of the chlorenchyma, transfusion tissue, and endodermis. Rehydration of such leaves may result in irreversible pseudoplasmolysis if dehydration is carried too far,

Assessing lethal and sub-lethal effects of trichlorfon on different trophic levels

Aquatic Toxicology, 2011
Trichlorfon (TCF) is one of the most used veterinary pharmaceuticals not only to fight infestations but also as a preventive measure worldwide. The high concentrations used generate concerns about environmental and human health. In this work we assessed the acute toxicity of this compound to non-target organisms belonging to different trophic levels ...

Immune response of Galleria mellonella after injection with non-lethal and lethal dosages of Candida albicans.

Journal of Invertebrate Pathology, 2020
The immune response of Galleria mellonella to injection with non-lethal and lethal dosages of Candida albicans was compared. Larvae infected with the non-lethal dosage (2×104 cells/larva) did not show significant morphological changes, while those ...

Immunoglobulin levels in Bull terriers suffering from lethal acrodermatitis

Veterinary Immunology and Immunopathology, 2003
An enzyme-linked immunosorbent assay, developed by one the authors (Huang, 1993) was used to measure immunoglobulin levels in previously stored plasma samples from eight dogs suffering from lethal acrodermatitis (LAD) and 10 normal Bull terriers. The aim of the study was to document plasma immunoglobulin levels and to determine if dogs suffering from ...

Lethal and sub-lethal effects of environmentally relevant levels of imidacloprid pesticide to Eastern School Prawn, Metapenaeus macleayi

Science of The Total Environment, 2020
Pesticides are frequently employed to enhance agricultural production. Neonicotinoid pesticides (including imidacloprid) are often used to control sucking insects but have been shown to impact aquatic crustaceans. Imidacloprid is highly water soluble and has been detected in estuaries where it has been applied in adjacent catchments.

Aroclor 1254� residues in birds: Lethal levels and loss rates

Archives of Environmental Contamination and Toxicology, 1984
Lethal residues of polychlorinated biphenyls (PCBs) were determined experimentally in four species of wild birds given dietary dosage of 1,500 ppm of Aroclor 1254® until one-half had died, sacrificing the survivors, chemically analyzing the tissues, and comparing results in dead birds and survivors. For all species, residues of 310 ppm or higher in the
