Effects of the European hornet ( Vespa crabro Linnaeus 1761) crude venom on its own species
Journal of Venomous Animals and Toxins including Tropical Diseases, 2013 Background Lethal dose 50% is a classical index of toxicity that usually employs small rodents as experimental animals. Therefore, scarce data are available on the effects of venom on invertebrates, particularly the impact of wasp venom on its own ...

Acute toxicity test in aquaculture: a review [PDF]
, 2013 Acute toxicity test involves estimation of LC50 or LD50 which is the concentration or dose which proved to be lethal causing death to 50% of the tested organisms. This article reviews the methods utilized for the determination of probit and LC50 and also

Aspergillus niger Spores Are Highly Resistant to Space Radiation [PDF]
, 2020 The filamentous fungus Aspergillus niger is one of the main contaminants of the International Space Station (ISS). It forms highly pigmented, airborne spores that have thick cell walls and low metabolic activity, enabling them to withstand harsh ...

Time Course of PR of UV-Induced Chromosomal Aberrations and Lethal Damage in S and G2 Xenopus Cells [PDF]
, 1979 Sand G2 phase cells were exposed to 150 ergs mm⁻² UV and their ability to photoreactivate the induced cell killing (loss of colony forming ability) and chromosomal aberrations was determined as a function of time following the UV exposure.

Liver-specific knockout of arginase-1 leads to a profound phenotype similar to inducible whole body arginase-1 deficiency [PDF]
, 2016 Arginase-1 (Arg1) converts arginine to urea and ornithine in the distal step of the urea cycle in liver. We previously generated a tamoxifen-inducible Arg1 deficient mouse model (Arg1-Cre) that disrupts Arg1 expression throughout the whole body and leads

Naturally occurring mutations in the PA gene are key contributors to increased virulence of pandemic H1N1/09 influenza virus in mice [PDF]
, 2014 We examined the molecular basis of virulence of pandemic H1N1/09 influenza viruses by reverse genetics based on two H1N1/09 virus isolates (A/California/04/2009 [CA04] and A/swine/Shandong/731/2009 [SD731]) with contrasting pathogenicities in mice.

Reversal of Sodium Arsenite Inhibition of Rat Liver Microsomal Ca2+ Pumping ATPase by Vitamin C [PDF]
, 1999 Sodium arsenite (NaAsO2), at 10% of its median lethal dose, was administered to rats with and without vitamin C pretreatment. Liver microsomal fraction was isolated and the activity of Ca2+-ATPase was assayed.
