Nonclinical safety assessment of an mRNA Covid ‐19 vaccine candidate following repeated administrations and biodistribution
AbstractMessenger RNA (mRNA) vaccines have demonstrated efficacy against Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) in humans. mRNA technology holds tremendous potential for rapid control and prevention of emergencies due to its flexibility with respect to production, application, and design for an efficacious and safe use in humans. We assessed the toxicity and biodistribution of MRT5500, an mRNA vaccine encoding for the full-length of the SARS-CoV-2 spike protein and delivered by lipid nanoparticles (LNPs) containing a novel ionizable lipid, Lipid-1 in preclinical animal models. In the repeated dose tox...

Developmental and reproductive toxicity hazard characterization of 2 ‐amino‐2‐methyl‐1‐propanol (AMP)
Abstract2-Amino-2-methyl-1-propanol (AMP ™) is a widely used pH stabilizer in personal care products (PCPs); thus, the safety implications of dermal AMP exposure remain of interest. We have previously reported that exposure to AMP in PCPs when used as intended is not anticipated to result in an increased risk of hepatotoxicity (primarily steatosis and altered phospholipid homeostasis). The current study focuses on AMP in PCP's potential for developmental and reproductive toxicity (DART) in humans, based on data from animal studies. Animal studies suggest that exposure to AMP can result in post-implantation loss. However,...

Suitability of different reconstructed human skin models in the skin and liver Chip2 microphysiological model to investigate the kinetics and first ‐pass skin metabolism of the hair dye, 4‐amino‐2‐hydroxytoluene
In conclusion, epidermal and FT skin models u sed in the Chip2 can mimic the first-pass skin metabolism of AHT. This highlights the flexibility of the Chip2 to incorporate different skin models according to the purpose. (Source: Journal of Applied Toxicology)

Snake venom toxins: Potential anticancer therapeutics
AbstractSnake venom contains a cocktail of compounds dominated by proteins and peptides, which make up the toxin. The toxin components of snake venom attack several targets in the human body including the neuromuscular system, kidney and blood coagulation system and cause pathologies. As such, the venom toxins can be managed and used for the treatment of these diseases. In this regard, Captopril used in the treatment of cardiovascular diseases was the first animal venom toxin-based drug approved by the US Food and Drug Administration and the European Medicines Agency. Cancers cause morbidity and mortality worldwide. Due to...
