Experiments comparing diploids with polyploids and in single grassland sites show that nitrogen and/or phosphorus availability influences plant growth and community composition dependent on genome size; specifically, plants with larger genomes grow faster under nutrient enrichments relative to those with smaller genomes. However, it is unknown if these effects are specific to particular site localities with speciifc plant assemblages, climates, and historical contingencies. To determine the generality of genome size-dependent growth responses to nitrogen and phosphorus fertilization, we combined genome size and species abundance data from 27 coordinated grassland nutrient addition experiments in the Nutrient Network that occur in the Northern Hemisphere across a range of climates and grassland communities.

- Intimate partner violence (IPV) is a common issue in the U.S., with orthopedic surgeons able to identify injuries related to IPV, since musculoskeletal injuries are frequently seen in victims.* -
- A systematic review analyzed 316 articles and included 16 studies, confirming that upper extremity fractures, particularly minimally displaced phalangeal fractures, are the most common injuries linked to IPV.* -
- The study provides valuable insights for physicians to recognize IPV through injury patterns, highlighting a need for more research on the topic due to the ongoing prevalence of IPV.*
Mucin-1 (MUC1) is a highly relevant antigen for cancer vaccination due to its overexpression and hypo-glycosylation in a high percentage of carcinomas. To enhance the immune response to MUC1, our group has developed C3-liposomes that encapsulate the MUC1 antigen along with immunostimulatory compounds for direct delivery to antigen-presenting cells (APCs). C3-liposomes bind complement C3, which interacts with C3-receptors on APCs, resulting in liposomal uptake and the delivery of tumor antigens to APCs in a manner that mimics pathogenic uptake.

Yet, this knowledge is of crucial importance in times of climate change and biodiversity loss. Here, we show that plant diversity is positively correlated with soil carbon content and soil carbon-to-nitrogen ratio across 84 grasslands on six continents that span wide climate gradients.

- Gastric cancer (GC) is a fast-growing and deadly cancer, ranking as the third leading cause of cancer-related deaths worldwide, with most patients diagnosed with advanced stages that are hard to treat.
- Traditionally, treatment options for advanced GC have been limited, relying mainly on chemotherapy and radiation, but recent advances have provided new insights into the immune and molecular factors driving the disease.
- New immunotherapies, such as immune checkpoint inhibitors and chimeric antigen receptor T-cell therapies, are emerging as promising treatments for certain patients with GC, pushing the boundaries of current medical approaches and highlighting the need for further research.
