Article Synopsis
  • Preterm infants are highly susceptible to iron deficiency, but understanding of their iron regulation is limited.
  • The research aimed to create a suitable animal model by inducing prematurity in piglets, allowing assessment of iron status similar to that of preterm human infants.
  • Findings showed that preterm piglets had lower body weight and plasma iron but higher tissue iron and levels of iron-regulatory hormones, indicating a unique pattern of iron metabolism that suggests functional iron deficiency and accumulation.

Article Synopsis
  • * The study investigated iron transfer efficiency across the placenta as a potential reason for the observed differences in iron status between wild boar and Polish Large White (PLW) piglets.
  • * Analysis revealed no major differences in iron transporter gene expression between the two species, but wild boar placentas showed higher levels of certain enzymes that aid in iron export to the fetus.

Background: The critically low hepatic iron stores of newborn piglets are considered to be a major cause of neonatal iron deficiency in modern breeds of domestic pig (Sus domestica). The main factor believed to contribute to this phenomenon is large litter size, which has been an objective of selective breeding of pigs for decades. As consequence, iron transferred from the pregnant sow has to be distributed among a greater number of fetuses.

Bioimage analysis plays a critical role in extracting information from biological images, enabling deeper insights into cellular structures and processes. The integration of machine learning and deep learning techniques has revolutionized the field, enabling the automated, reproducible, and accurate analysis of biological images. Here, we provide an overview of the history and principles of machine learning and deep learning in the context of bioimage analysis.

Kidneys are pivotal organ in iron redistribution and can be severely damaged in the course of hemolysis. In our previous studies, we observed that induction of hypertension with angiotensin II (Ang II) combined with simvastatin administration results in a high mortality rate or the appearance of signs of kidney failure in heme oxygenase-1 knockout (HO-1 KO) mice. Here, we aimed to address the mechanisms underlying this effect, focusing on heme and iron metabolism.
