Penn researchers receive nearly $5 million to reduce opioid cravings

Opioid overdoses take the lives of tens of thousands of Americans annually. Two researchers from Penn State College of Medicine have received nearly $5 million from the National Institutes of Health to study whether an already-approved drug can be used to reduce cravings and prevent relapse in those struggling with opioid addiction.

Research asserts ability of DRS technique to characterize healthy and non-healthy tissue

In an article published in the peer-reviewed SPIE publication Journal of Biomedical Optics (JBO), "Influence of neoadjuvant chemotherapy on diffuse reflectance spectra of tissue in breast surgery specimens," research observed across 92 ex vivo breast specimens suggests that there is little to no impact on the optical signatures of breast tissue after neoadjuvant chemotherapy.

Improved optical imaging technique can help identify patients at risk of future heart attacks

Doctors need better ways to detect and monitor heart disease, the leading cause of death in industrialized countries. A team led by Massachusetts General Hospital researchers with support from the National Institute of Biomedical Imaging and Bioengineering has developed an improved optical imaging technique that found differences between potentially life-threatening coronary plaques and those posing less imminent danger for patients with coronary artery disease.

Label-free multimodal imaging platform enables non-invasive study of cell cultures

Most analytical methods in biology require invasive procedures to analyze samples, which leads to irreversible changes or even their destruction.

Uncovering the secret weapon of rabies viruses

In a new study published in the journal Cell Reports, scientists have discovered the exact site at which the immune system is disabled by the rabies virus, opening the way for a new and highly effective means of rabies prevention. This is a long-awaited discovery and could transform the field of rabies immunization.

TSU researchers develop new approach to diagnose adenocarcinoma

Scientists have developed a new approach to the diagnosis of adenocarcinoma - a malignant tumor of the prostate gland. Artificial intelligence is used to determine oncopathology and determine the stage of the disease with this approach.

Fluorescent carbon dots can effectively detect calcium levels in cells

In hospitals, doctors often advise patients to take calcium supplements. But does the calcium get into the cells that need it? Until recently, it's been hard to tell.

Properties of spider silk proteins could be selectively modified to synthesize novel biomaterials

Spider silk consists of fiber-forming proteins, stored by the spider in a specialized gland. When the spider needs silk, for instance to build a web, it extrudes the silk proteins through a long duct in which they are exposed to specific mechanical and chemical influences and assembled to form silk.

Increasing anti-tumor activity of compound extracted from an Amazon plant

Researchers in Brazil have prepared modified forms of the alkaloids produced by Uncaria guianensis, a woody vine native to the Amazon Rainforest.

Drug delivery still has great development potential

Nanocapsules and other containers can transport drugs through a patient's body directly to the origin of the disease and release them there in a controlled manner. Such sophisticated systems are occasionally used in cancer therapy. Because they work very specifically, they have fewer side effects than drugs that are distributed throughout the entire organism.
