To determine whether enteral deferiprone given after a loading dose of liquid iron interferes with iron absorption from the digestive tract, prospective randomized animal study was initiated using Sprague-Dawley rats. The rats were given 20 mg elemental iron/kg as a ferrous sulfate solution + 1 mEq sodium bicarbonate/kg, and then dosed orally with 150 mg deferiprone/kg immediately or after 15 min. Serum iron levels were measured at 1, 3, 5 and 24 h; feces were collected for 24 h. The 20 mg elemental iron/kg caused a significant and rapid increase in serum iron levels to > 350 micrograms/dL within 20 min of oral dosing. Deferiprone, if given immediately after the iron, produced a significant decrease in serum iron levels and a 2-fold increase in iron excretion in feces. Effectiveness was delayed when the deferiprone was given 15 min after the iron dosing. Enteral deferiprone might be useful in preventing cases of acute iron intoxication.

Objective: Post-resuscitation brain injury is a common sequela after cardiac arrest (CA). Increasing sirtuin1 (SIRT1) has been involved in neuroprotection in oxygen-glucose deprivation (OGD) neurons, and we investigated its mechanism in post-cardiopulmonary resuscitation (CPR) rat brain injury by mediating p65 deacetylation modification to mediate hippocampal neuronal ferroptosis.
Methods: Sprague-Dawley rat CA/CPR model was established and treated with Ad-SIRT1 and Ad-GFP adenovirus vectors, or Erastin.

Background: Our studies suggest that iron-overloaded rats developed neurotoxicity and cognitive impairment (1,2). An increase in brain mitochondrial fission and brain mitophagy have been considered as one of underlying mechanisms in brain with iron-overloaded condition (3,4). Hence, a pharmacological intervention focused on preventing brain mitochondrial pathologies is required.

Background: Thalassemia is a hereditary disease with impaired red blood cell production, resulting in cumulative systemic iron burden. The life-long therapeutic blood transfusion with or without iron chelators in those patients leads to the development of early-onset neurocognitive decline. However, the effects of regularity of blood transfusion on the severity of iron burden, cognitive decline, and gut dysbiosis in thalassemia patients are still unclear.

Background: Cerebrovascular accidents are known as a great cause of morbidity and mortality worldwide. Although there are known risk factors for ischemic stroke, the cases that cannot be justified with these risk factors are increasing. Toxic metals as a potential risk factor for other diseases in humans are assessed in this study in the CVA group and compared to controls.

The rapidly aging population is fueling a surge in diabetes, especially Type 2, which heightens colorectal cancer (CRC) risk. Colorectal adenoma, a precursor, compounds this trend. Although alpha-glucosidase inhibitors are effective hypoglycemic drugs working in the GI tract, the link between them and colorectal adenoma formation remains unexplored.
