Relationship between blood Lead status and anemia in Ugandan children with malaria infection

open access: yesBMC Pediatrics, 2020
Background In Uganda, childhood anemia remains a health challenge and is associated with malaria infection as well as iron deficiency. Iron deficiency is intertwined with nutritional status, age and other comorbidities including helminths and Lead ...

Zinc protoporphyrin binding to telomerase complexes and inhibition of telomerase activity*

open access: yesPharmacology Research & Perspectives, 2021
Zinc protoporphyrin (ZnPP), a naturally occurring metalloprotoporphyrin (MPP), is currently under development as a chemotherapeutic agent although its mechanism is unclear.

Eggshell spottiness reflects maternally transferred antibodies in blue tits. [PDF]

open access: yesPLoS ONE, 2012
Blue-green and brown-spotted eggshells in birds have been proposed as sexual signals of female physiological condition and egg quality, reflecting maternal investment in the egg. Testing this hypothesis requires linking eggshell coloration to egg content,

Formation of meso, N-diphenylprotoporphyrin IX by an aerobic reaction of phenylhydrazine with oxyhemoglobins. [PDF]

open access: yes, 2003
Administration of phenylhydrazine to rabbits resulted in the denaturation of hemoglobins in erythrocytes, causing the formation of intracellular precipitates known as Heinz bodies, severe hemolytic anemia, and reticulocytosis.

Metalloporphyrins inactivate caspase-3 and -8 [PDF]

open access: yes, 2005
Activation of caspases represents one of the earliest biochemical indicators for apoptotic cell death. Therefore, measurement of caspase activity is a widely used and generally accepted method to determine apoptosis in a wide range of in vivo and in ...

A novel high-content immunofluorescence assay as a tool to identify at the single cell level γ-globin inducing compounds [PDF]

open access: yes, 2015
The identification of drugs capable of reactivating γ-globin to ameliorate β-thalassemia and Sickle Cell anemia is still a challenge, as available γ-globin inducers still have limited clinical indications.

Protoporphyrin Treatment Modulates Susceptibility to Experimental Autoimmune Encephalomyelitis in miR-155-Deficient Mice.

open access: yesPLoS ONE, 2015
We previously identified heme oxygenase 1 (HO-1) as a specific target of miR-155, and inhibition of HO-1 activity restored the capacity of miR-155-/- CD4+ T cells to promote antigen-driven inflammation after adoptive transfer in antigen-expressing ...

Heme oxygenase 1 is differentially involved in blood flow-dependent arterial remodeling: role of inflammation, oxidative stress, and nitric oxide [PDF]

open access: yes, 2011
Heme oxygenase 1 is induced by hemodynamic forces in vascular smooth muscle and endothelial cells. We investigated the involvement of heme oxygenase 1 in flow (shear stress)-dependent remodeling.

Prolonged Allogeneic Islet Graft Survival by Protoporphyrins

open access: yesCell Transplantation, 2005
Transplantation of islets of Langerhans in patients with type 1 diabetes allows for improved metabolic control and insulin independence. The need for chronic immunosuppression limits this procedure to selected patients with brittle diabetes.
