Background: In response to iron deficiency and other environmental stressors, cyanobacteria producing siderophores can help in ameliorating plant stress and enhancing growth physiological and biochemical processes. The objective of this work was to screen the potential of Arthrospira platensis, Pseudanabaena limnetica, Nostoc carneum, and Synechococcus mundulus for siderophore production to select the most promising isolate, then to examine the potentiality of the isolated siderophore in promoting Zea mays seedling growth in an iron-limited environment.
Results: Data of the screening experiment illustrated that Synechococcus mundulus significantly recorded the maximum highest siderophore production (78 ± 2%) while the minimum production was recorded by Nostoc carneum (24.

Toxoplasmosis induced by Toxoplasma gondii is a well-known health threat, that prompts fatal encephalitis increased with immunocompromised patients, in addition, it can cause chorioretinitis, microcephaly, stillbirth in the fetus and even led to death. Standard therapy uses sulfadiazine and pyrimethamine drugs revealed beneficial results during the acute stage, however, it has severe side effects. UPLC-ESI-MS/MS used to explore C.

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.

Iron overload has been associated with cerebrovascular disease and cognitive impairment in β-thalassaemia patients, typically appearing earlier than in the general population. However, the mechanisms of iron overload on cerebrovascular pathology remain unclear. This study investigated the effects of heavy iron overload on the blood-brain barrier and neurohistology, particularly in the CA3 region of hippocampus and its contribution to cognitive impairment in β-thalassaemia mice.
