Bees play a crucial role as pollinators, significantly contributing to ecosystem health. However, they face growing threats from human activities. This study uses biomarkers to evaluate the health status of Melipona mandacaia, a stingless bee native to the Caatinga biome, as indicators of anthropogenic stress.

- * Conducted on 65 CD patients, the findings showed that 32 exhibited the bright luminal sign, which demonstrated high sensitivity (90%) and specificity (85%) in identifying fibrotic strictures when compared with other imaging techniques.
- * The results suggest that DWI hyperintensity could serve as a non-invasive indicator for detecting severe intestinal fibrosis, aiding in early diagnosis and potentially preventing complications. However, further research with larger
Brazil is an important global agricultural producer and to increase production the country has extensively used glyphosate-based herbicides (GBH), surpassing consumption and sales records. Consequently, concerns have arisen regarding the potential impact of GBH on ecosystems and non-target organisms. Thus, the effects of GBH exposure were evaluated throughout the cricket Gryllus (Gryllus) assimilis ontogeny, with five developmental stages.

- Anderson-Fabry disease (AFD) is a rare genetic disorder that leads to organ damage due to a lack of α-galactosidase A, causing harmful substances to accumulate in tissues, particularly affecting the heart and kidneys.
- * Researchers conducted a study using cardiovascular magnetic resonance (CMR) and T1 mapping to evaluate kidney involvement in 19 AFD patients compared to a control group without kidney disease.
- * The findings indicated a positive correlation between heart and kidney T1 values in AFD patients, and a negative correlation in kidney T1 values between AFD and control patients, suggesting kidney damage from microvascular issues in AFD.
In recent years, the use of cardiac magnetic resonance (CMR) has grown exponentially in clinical practice. The keys for this success are represented by the possibility of tissue characterization, cardiac volumes and myocardial perfusion assessment, biventricular function evaluation, with no use of ionizing radiations and with an extremely interesting profile of reproducibility. The use of late gadolinium enhancement (LGE) nearly compares a non-invasive biopsy for cardiac fibrosis quantification.
