Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1435-1447, May 2026.ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)
International Journal of Climatology, Volume 46, Issue 6, May 2026.This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends
International Journal of Climatology, Volume 46, Issue 6, May 2026.Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Intratumoral Microorganisms in Tumors: Current Understanding and Emerging Therapeutic Strategies
MedComm, Volume 7, Issue 5, May 2026.Tumors are no longer viewed as sterile but dynamic ecosystems harboring low‐biomass intratumoral microbiota. These microbes, derived from gut, oral cavity, or circulation, shape tumorigenesis and therapy response via core mechanisms: immunomodulation (regulating T cells, macrophages), metabolic reprogramming (SCFAs, indoles, bile acids), chronic ...
