Background: Root growth is most commonly determined with the destructive soil core method, which is very labor-intensive and destroys the plants at the sampling spots. The alternative minirhizotron technique allows for root growth observation throughout the growing season at the same spot but necessitates a high-throughput image analysis for being labor- and cost-efficient. In this study, wheat root development in agronomically varied situations was monitored with minirhizotrons over the growing period in two years, paralleled by destructive samplings at two dates.

Article Synopsis
  • Glofitamab, a bispecific antibody targeting CD20 and CD3, shows promise for treating relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL) in heavily pretreated patients, with an overall response rate of 47%.
  • In a study involving 70 patients in Germany, Austria, and Switzerland, the median number of prior treatments was four, with notable safety concerns including cytokine release syndrome in 40% of cases.
  • Important findings indicate that elevated LDH levels predict poorer outcomes, and recent treatment with bendamustine may reduce the efficacy of glofitamab, suggesting careful treatment sequencing is essential.

Article Synopsis
  • Allogeneic stem cell transplantation (alloSCT) is an effective treatment to cure patients with relapsed/refractory (r/r) aggressive lymphomas, particularly focusing on peripheral T-cell lymphoma (PTCL) and diffuse large B-cell lymphoma (DLBCL).
  • The study found that patients with PTCL had significantly better outcomes compared to those with DLBCL in terms of 5-year progression-free survival (PFS) and overall survival (OS), especially after the first 100 days post-transplant.
  • Despite similar rates of non-relapse mortality, DLBCL patients faced higher rates of relapse mortality, and the presence of extensive chronic graft-versus-host disease (GvHD) negatively impacted outcomes for both

Background: Quantification of Amyloid beta (Aβ) oligomers in plasma enables early diagnosis of Alzheimer's Disease (AD) and improves our understanding of underlying pathologies. However, quantification necessitates an extremely sensitive and selective technology because of very low Aβ oligomer concentrations and possible interference from matrix components.

Methods: In this report, we developed and validated a surface-based fluorescence distribution analysis (sFIDA) assay for quantification of Aβ oligomers in plasma.

Article Synopsis
  • Plant communities consist of species with varying functional traits and evolutionary backgrounds, leading to the expectation that functional diversity increases with phylogenetic diversity.* -
  • Contrary to this expectation, a study of over 1.7 million vegetation plots showed that functional and phylogenetic diversity are weakly and negatively correlated, suggesting they operate independently.* -
  • Phylogenetic diversity is more pronounced in forests and reflects recent climate, while functional diversity is influenced by both past and recent climate, highlighting the need to assess both types of diversity for ecosystem studies and conservation strategies.*
