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...

The shape of pleomorphic virions determines resistance to cell-entry pressure

The study of viruses is a never-ending battle. Even for well-studied viruses such as the influenza A virus, scientists are continuing to discover new data. A research group in Brandeis University has begun to study the particle structure of viruses...

Researchers Investigate Six Common Pesticides in Wines and the Associated Risk Assessments

Romanian scientists¹ have developed a quick and easy analytical method to determine if wines contain pesticide residues less than the European Union’s maximum residue limits. They focused on the detection of six pesticide residues in red, rosé, and white wines....

Strong cation Exchanger (BCX) cited in a study on a radiopharmaceutical for Neuroendocrine tumor

With a growing interest in clinical applications in recent years, the demand for Gallium-68 (68Ga) has also increased. 68Ga-DOTATATE is used as a radiotracer in Positron Emission Tomography (PET) to detect and evaluate cancer-causing Neuroendocrine tumor (NET) cells. A particle accelerator, Cyclotron,...

An Electrochemiluminescence Biosensor for Detection of CdkN2A/p16 Anti-oncogene Based on Functional Electrospun Nanofibers and Core-shell Luminescent Composite Nanoparticles

In the pursuit of cancer research and clinical applications, one of the most important factors is the recognition and quantitation of the CdkN2A/p16 anti-oncogene, AKA the multiple tumor suppressor 1 gene (MTS1). This gene is associated with metastatic spread of...

A New Single-Laboratory Validated Method for the Detection of Pyrethroid Metabolites in Milk by GC/MS

With concerns over the household use of pyrethroid pesticides for mosquito control, researchers in Thailand have developed a validated method for analyzing cis/trans-permethrinic acid in powdered milk. Pyrethroids are naturally occurring pesticides that are synthesized to manufacture mosquito coils and...

Importance of umbilical cord analysis in determining prenatal drug exposure

Fentanyl serves as a powerful analgesic agent to manage pain during labor and delivery. However, prolonged prenatal exposure can make babies drug dependent and sudden discontinuation may result in conditions like Neonatal Abstinence Syndrome (NAS) or Neonatal Opioid Withdrawal Syndrome...

Myelination and Node of Ranvier Formation in a Human Motoneuron−Schwann Cell Serum-Free Coculture

Motor neurons allow the body to move, speak, and breathe due to the propagation of action potentials between neuron nodes. The space between neurons, known as a node of Ranvier, are protected by a myelin sheath. When these nodes or...

Fungicides Affect Leafy Vegetable Biochemistry

Researchers at the Institute of Plant Protection-National Research Institute and the Academy of Agrobusiness in Poland determined individual fungicides, Fluazinam, Dithianon, and Dodine, and mixtures of the three fungicides cause diverse effects in leafy vegetables. When researchers mixed the herbicides,...
