Simpler test that can be done in doctor’s office offers results in 30 minutes. An improved urine-testing system for people suffering from kidney stones inspired by nature and proposed by researchers from Penn State and Stanford University may enable patients to receive results within 30 minutes instead of the current turnaround time of a week or more.

Kidney stones occur due to buildup of certain salts and minerals that form crystals, which in turn stick together and enlarge to form a hard mass in the kidneys...

Scientists from the Antibody and Vaccine group at the University of Southampton have discovered a way to transform antibody drugs previously developed to treat autoimmunity into antibodies with powerful anti-cancer activity through a simple molecular “switch.”

This work, published in the journal Cancer Cell, focuses on a molecule called CD40 which is present on the surface of immune cells and controls both autoimmunity and cancer. In autoimmunity, CD40 is thought to be over-stimulated, increasing the chance of the immune system attacking healthy tissues; whereas in cancer, CD40 is believed to be under-stimulated, enabling tumour cells to evade the immune system. Targeting of CD40 with antibody drugs is ongoing in therapeutic interventions for both diseases.

Accordingly, antibody...

In a randomized, controlled feeding study, the researchers found that when participants ate a meal high in fat and carbohydrates with six grams of a spice blend added, the participants had lower inflammation markers compared to when they ate a meal with less or no spices.

“If spices are palatable to you, they might be a way to make a high-fat or high-carb meal more healthful,” said Connie Rogers, associate professor of nutritional sciences. “We can’t say from this study if it was one spice in particular, but this specific blend seemed to be beneficial.”

The researchers used a blend of basil, bay leaf, bl...

Dr. Akhilesh K. Gaharwar, associate professor, has developed a highly printable bioink as a platform to generate anatomical-scale functional tissues. This study was recently published in the American Chemical Society’s Applied Materials and Interfaces.

Bioprinting is an emerging additive manufacturing approach that takes biomaterials such as hydrogels and combines them with cells and growth factors, which are then printed to create tissue-like structures that imitate natural tissues.

One application of this technology could be designing patient-specific bone grafts, an area that is gaining interest from researchers and clinicians. Managing bone defects and injuries through traditional treatments tends to be slow and expensive...
