MedicalResearch.com: What is the mission of Singh Biotechnology?
- Our mission is to develop medicine and therapeutics that dramatically improve and save the lives of people worldwide suffering from diseases, including cancer.
- The average human antibody is 150 Kd in size and works on the outside of the cell. The advantage of the single domain nanobody is that it is significantly smaller, in fact, it is one-tenth the size (approximately 15 Kd) of the human antibody. A smaller nanobody is more useful therapeutically because, unlike many cancer drugs currently on the market, it can penetrate the blood-brain barrier, the blood-retina barrier, and the cell membrane. Moreover, our SBT-100 drug has been shown to be non-toxic in animal models.

MedicalResearch.com: What is the background for this study?
Response: People infected with COVID-19 can release SARS-CoV-2 virus in aerosol and droplets when they exhale. This can be from coughing or sneezing but also when they speaker or just breathe. While the larger droplets can settle to the ground quickly (seconds to minutes), smaller aerosol can remain in the air in longer periods (minutes to hours). SARS-CoV-2 can be transmitted by inhaling aerosol or droplets containing infectious virus. The Fresh Air Clip enables detection of droplet and aerosol containing virus.

MedicalResearch.com: What is the background for this study? Where is triclosan commonly found?
Response: Triclosan is a commonly found antibacterial compound present in hand soaps, toothpastes, athletic clothes, and children’s toys. A previous study by the Zhang group (corresponding author on this publication) found that antimicrobial compounds including triclosan increased inflammation (similar to that of inflammatory bowel disease (IBD)) and tumor formation in the colon. These effects were observed only in mice with an intact gut microbiome, not in germ-free mice which lack a gut microbiome, suggesting that the gut microbiome is somehow responsible for the toxicity of triclosan to the gut. Our study investigates how gut bacteria promote triclosan toxicity in the gut
