Hybrid lethality is a deleterious phenotype that is vital to species evolution. We previously reported hybrid lethality in cabbage (Brassica oleracea) and performed preliminary mapping of related genes. In the present study, the fine mapping of hybrid lethal genes revealed that BoHL1 was located on chromosome C1 between BoHLTO124 and BoHLTO130, with an interval of 101 kb. BoHL2 was confirmed to...
OBJECTIVE This study was aimed at identifying the most common risk factors associated with suicide attempts to determine differences between risk factors present in patients regarding their low-lethality and high-fatality suicide attempts. METHOD 106 patients from both sexes who had been hospitalised in a psychiatric unit following their attempts at suicide were interviewed; they were divided...
High throughput imaging is used to assess hatching, lethality and malformations in zebrafish embryos suitable for hazard ranking of different nanomaterials.
Background and objectives: Ferula gummosa Boiss. (Umbelliferae) is a popular medicinal plant, which is known mostly for therapeutic uses of its oleo-gum-resin (Barijeh in Persian). In the present study, the essential oil of F. gummosa roots was investigated for its phytochemical constituents, antioxidant activity and toxicity potential. Method...
Introduction: Photothermal therapy is a method of cancer treatment that plasmonic nanoparticles are used to convert infrared light into local heat. Due to the plasmonic properties of gold nanoparticles, this compound was used as a contrast agent. The aim of this study was to synthesize gold nanoparticles with different conjugations for photothermal therapy. Methods: This research was an experi...
Intensification of agricultural practices is one the most important drivers dramatic decline arthropod species. We do not know, however, relative contribution to different anthropogenic stressors that are part this process. used high-resolution dynamic landscape models and advanced spatially-explicit population modelling estimate importance insecticide use structure for dynamics a widespread ca...
Planning for and managing radiological terrorism incidents that involve the release of radionuclides from a dirty bomb requires considering the potential lifesaving impact of protective radionuclide decorporation countermeasures (e.g., lung lavage). Lung lavage therapy could prevent deaths via the pulmonary mode (which involves radiation pneumonitis and fibrosis) by reducing the radiation dose ...
AIM To test the hypothesis that lethal toxins of bacteria associated with sudden infant death syndrome (SIDS) can act synergistically. METHODS Bacteria occurring together in the nasopharynx of cases of cot death were studied. The lethal toxicity of crude toxin preparations was determined over a range of dilutions by injections into the chorioallantoic vein of the chick embryo. Toxin preparati...
