Clean Screen XCEL I Used to Confirm Fentanyl Overdose in Italian Case Study

Fentanyl, a well-known synthetic opioid approximately 100 times more potent than morphine, continues to be a public health issue. In cases of a fentanyl overdose, it is difficult to determine the cause of death based on toxicological information alone due...

Physicochemical Properties Predict Retention of Antibiotics in Water-in-Oil Droplets

The ability to study antibiotic resistant pathogens by using methods such as antimicrobial susceptibility testing (AST) is important, especially with the rapid emergence of more and more antibiotic resistant pathogens. AST is a method with uses droplets of solutions as...

The use of Liquid Chromatography-Mass Spectroscopy to Determine Specific Second-Generation Rodenticide Diastereomer Ratios Within Wildlife Liver Samples: The Pursuit Towards a Safer Bait Formula

A recently published master’s thesis from UC Davis discusses rodenticide diastereomers in wildlife liver samples. Liver samples from both targeted and non-target wildlife were analyzed for this project. Non-target species included coyotes, gray foxes, and cougars. The student used chicken...

Testing of drugs using human feto-maternal interface organ-on-chips provide insights into pharmacokinetics and efficacy

There are a very limited number of medical interventions to prevent placental-mediated adverse pregnancy outcomes, such as preterm birth (PTB) and no interventions available for pre-eclampsia (PE). This is because pharmaceuticals are unable to cross feto-maternal interface (FMi) barriers and...

Researchers study the targeted and non-targeted analysis of pesticides in wheat and investigate pesticides’ influence on wheat cultivated under field conditions.

High-Resolution Optical Tweezers Combined with Multicolor Single-Molecule Microscopy

Optical tweezers (OT) are a device that can manipulate individual molecules with cells by using light from low-wattage lasers and are used to study and manipulate DNA and RNA. There is a serious limitation to these optical tweezers. They can...
