Background: Arterial stiffness is associated with higher burden of atrial arrhythmias and worsening left atrial function (conduit and reservoir), even before dilation of this cavity. PACs: premature atrial contractions; cfPWV: carotid-femoral pulse wave velocity.
Background: Increased arterial stiffness is currently an independent risk factor for atrial fibrillation, but the pathophysiological mechanisms of this arrhythmia remain an area of knowledge gap to be explored.
Heavy Metal Contamination in Birds from Protected Regions in the Amazon.
Environ Toxicol Chem
December 2024
Article Synopsis
- The rise in crude oil and gold extraction has led to increased heavy metal contamination in the environment, but research on its impact on wildlife is still limited, especially in biodiverse regions.
- A study of wedge-billed woodcreepers in the Amazon revealed elevated heavy metal levels in their feathers near extraction sites, as well as unexpected contamination levels in more remote areas.
- These findings emphasize the need to investigate the ecological and biological effects of heavy metal exposure on wildlife, even in areas thought to be unaffected by human activity, using data from native bird populations as indicators.
Article Synopsis
- The white-bellied pangolin, the most trafficked mammal, is nearing extinction and understanding its trafficking origins is crucial for combating this issue.
- A genomic analysis of 111 samples from Africa and 643 confiscated scales from Asia revealed a shift in poaching from West to Central Africa, particularly around Cameroon's southern border.
- The research identified Nigeria as a key trafficking hub for pangolin scales, providing new insights to inform anti-trafficking strategies and disrupt illegal wildlife trade.
Article Synopsis
- Renewable energy development is crucial for meeting global energy needs and addressing climate change, but its effects on wildlife need further investigation.
- Traditional methods for identifying bird species from collected samples can miss many due to difficulties in recognizing partial remains, or "feather spots."
- A DNA barcoding technique utilizing mitochondrial genetic data was successfully applied to identify bird samples from solar facilities, improving the accuracy of wildlife impact assessments and enabling better comparisons across different energy projects.
Article Synopsis
- - In primary myelofibrosis, extra-domain A fibronectin (EDA-FN) promotes megakaryocyte growth and causes inflammation in bone marrow environments.
- - A study of 122 patients showed that those with a homozygous JAK2V617F genotype had the highest levels of EDA-FN in their plasma, which correlated with other health issues like anemia and thrombosis.
- - Elevated EDA-FN levels at diagnosis may predict the severity of splenomegaly and could serve as an important marker for disease progression and potential treatment targets in primary myelofibrosis.
