The extent of resection has been reported to be associated with overall survival in gliomas. The use of 5-aminolevulinic acid (5-ALA) has been recognized to increase the extent of tumor resection. To evaluate what factors affect the intraoperative fluorescence after administration of 5-ALA in gliomas. Correlation of intraoperative fluorescence and ...

Chickpea (Cicer arietinum) belonging to the Fabaceae family is a major legume crop and is a good source of protein and carbohydrates. Industrialization has resulted in soil contamination with heavy metals such as cadmium. Adsorption of cadmium by plants can lead to reduced yields and heavy metal toxicity. In the current study, changes in the anatom...

Fluorescence image guided surgical resection (FIGR) of high grade gliomas (HGGs) takes advantage of the accumulation of the tracer protoporphyrin IX (PpIX) in glioma cells following administration of 5-aminolevulinic acid (5-ALA). Occasionally, PpIX fluorescence intensity may be insufficient, thus compromising the efficacy and precision of the surg...

The erythropoietic porphyrias are inborn errors of heme biosynthesis with prominent cutaneous manifestations. They include autosomal recessive Congenital Erythropoietic Porphyria (CEP) due to loss-of-function (LOF) mutations in the Uroporphyrinogen III Synthase (UROS) gene, Erythropoietic Protoporphyria (EPP) due to LOF mutations in the ferrochelat...

BackgroundMost species of Shewanella harbor two ferrochelatase paralogues for the biosynthesis of c-type cytochromes, which are crucial for their respiratory versatility. In our previous study of the Shewanella loihica PV-4 strain, we found that the disruption of hemH1 but not hemH2 resulted in a significant accumulation of extracellular protoporph...

Glutamyl-tRNA reductase1 (HEMA1) and ferrochelatase1 (FC1) are both expressed in response to salt stress in the biosynthetic pathway of tetrapyrroles. Peanut (Arachis hypogaea L.) HEMA1 and FC1 were isolated by RT-PCR. The amino acid sequence encoded by the two genes showed high similarity with that in other plant species. The AhFC1 fusion protein ...
Erythropoietin (EPO) signaling is critical to many processes essential to terminal erythropoiesis. Despite the centrality of iron metabolism to erythropoiesis, the mechanisms by which EPO regulates iron status are not well-understood. To this end, here we profiled gene expression in EPO-treated 32D pro-B cells and developing fetal liver erythroid c...

Horseradish peroxidase (HRP) is widely used as a marker enzyme in immunoassays and biosensors, and can possibly be used in industries such as waste water treatments or fine chemical synthesis. Cost-effective production of active HRP is thus very important in the related fields. Also, engineering of HRP for its better performance in the designated a...
