Italian researchers found a 40% relative reduction in endometriosis risk among women consuming higher amounts of green vegetables and fresh fruit. Conversely, high consumption of beef, other red meat, and ham was associated with an increased risk, potentially leading to a 3-4% decrease in prevalence if confirmed by future studies.
Researchers have found that male breast cancer incidence has increased by 26% over the past 25 years, with men being diagnosed at a later stage than women. The study also revealed differences in tumor biology, including higher rates of estrogen receptor-positive tumors in men.
Scientists at Johns Hopkins University have developed a new biomaterial that can promote cell growth and differentiation, potentially aiding in the repair of human tissue. The self-assembling protein gel is made from genetically engineered modular proteins that can be mixed to create different types of hydrogels for specific applications.
A research team at MGH has successfully grown long-lasting blood vessels using a technique that combines endothelial and perivascular cells. The new vessels formed beautiful networks, survived, and functioned like normal vasculature tissue.
Researchers develop a novel treatment to stimulate natural cartilage tissue growth in knee joint defects, providing a potential solution for osteoarthritis treatment. The hyaluronan-based polymer creates a protective cap and enables new cartilage tissue to grow, filling the defect and promoting healing.
Researchers develop a method to capture enzyme activity in real-time, revealing detailed information about molecular interactions. This breakthrough enables the design of targeted synthetic drugs for cancer treatment.
Tissue engineers can now monitor the growth and differentiation of cells in three-dimensional scaffolds with unprecedented depth. This breakthrough provides a crucial capability for the emerging field of tissue engineering, which aims to regenerate form and function in damaged or diseased tissues and organs.
Researchers developed VEGF-TRAP, an injection that prevents new blood vessel growth in the eyes of mice. The treatment halted existing vessel leakage and showed long-lasting effects without complications. It may offer a potential treatment for diabetic retinopathy and macular degeneration.
Researchers found that men with male breast cancer are more likely to be older when diagnosed, have later stage disease, and ductal papillary cancers. The study suggests important biological differences between male and female breast cancer.
Researchers have found a possible association between IVF and an increased risk of Beckwith-Wiedemann syndrome (BWS), a genetic disorder that can predispose children to cancer. BWS is characterized by excessive growth and occurs in about 1 in 15,000 births, with the incidence being significantly higher among IVF-conceived babies.
Researchers used Diffusion-Weighted Magnetic Resonance Imaging (DWMRI) to visualize and measure water characteristics in mouse tumors before and after chemotherapy. They found a significant correlation between water diffusion properties prior to treatment and subsequent tumor growth rate.
