BACKGROUND Hereditary angioedema (HAE) with normal C1 inhibitor (C1-INH) is a rare disorder. Mutations of the gene encoding coagulation factor XII have been identified in a subset of patients with this condition. Our aim was to investigate mutations in the F12 gene in patients with HAE with normal C1-INH from Brazil. METHODS We studied 5 Brazilian families with index female patients who prese...
A healthy Japanese male had reduced factor XII (FXII) activity (35%) in contrast to normal antigen levels (81%). The F12 of this proband had a 9775G to C mutation in exon 10 and an 11276G to A mutation in exon 13 that resulted in two amino acid substitutions of Ala324Pro (GCG→CCG) in the proline-rich connecting region and Gly531Glu (GGG→GAG) near the active Ser544 in the catalytic domain. His f...
BACKGROUND Recently there has been a remarkable surge of interest about natural products and their applications in the cosmetic industry. Topical delivery of antioxidants from natural sources is one of the approaches used to reverse signs of skin aging. The aim of this research was to develop a nanoemulsion cream for topical delivery of 30% ethanolic extract derived from local Phyllanthus urina...
The ,8-chain of rhinoceros hemoglobin contains glutamic acid at position ,82, an important site for the binding of organic phosphates. We have investigated the oxygen binding properties of this hemoglobin and its interaction with ATP, 2,3-diphosphoglycerate, CO 2 and chloride. The results show that the presence of GLU at position ,82 nearly abolishes the effect of organic phosphates and CO2, wh...
Hypoxia is a characteristic feature of solid tumors, leading to malignant behavior. During this process, HIF family members (HIFs) and the NF-κB pathway are activated. In addition, the hypoxia-associated factor (HAF) is reported to participate in the regulation of HIFs. However, the precise relationship among HIFs, HAF and the NF-κB pathway in bladder cancer (BC) remains unknown. In the current...
It was previously shown that serum low density lipoprotein (LDL) binds to type I collagen gels and that the binding is increased after modification by cultured endothelial cells. It is now demonstrated that when LDL is incubated with cells cultured in Dulbecco's modified minimal essential medium (DMEM), the subsequent binding of LDL to collagen is considerably less than after incubation with en...
HeLa cells grow in a nutritionally complete synthetic medium (Ham's F12) supplemented with insulin, transferrin, hydrocortisone (aldosterone), fibroblast growth factor, and epidermal growth factor. This hormone-supplemented medium supports clonal growth, long-term cultivation, and a growth rate equal to that of serum-supplemented medium. The omission of any one of the five components results in...
A dominant firm holding import quota engages in inter-temporal price discrimination when facing a competitive fringe engaged in seasonal production. This causes a welfare loss that comes in addition the loss attributable to limitation of imports below the free trade level. JEL classification: F12, F13
