Algicidal bacteria offer a promising option for killing cyanobacteria. Therefore, a new Alcaligenes aquatilis strain F8 was isolated to control Microcystis aeruginosa in this study. The algicidal activity of strain F8 was dependent on the cell density of M. aeruginosa, and the maximal algicidal rate of the free bacterium reached 88.45% within 72 h. With a view to its application to the control ...

Tissue factor pathway inhibitor (TFPI) blocks thrombin generation via the extrinsic blood coagulation pathway. Because the severe bleeding in patients with hemophilia occurs from deficiency of intrinsic blood coagulation pathway factor VIII or IX, pharmacological agents that inactivate TFPI and, therefore, restore thrombin generation via the extrinsic pathway, are being developed for treatment ...

BACKGROUND Single base-pair substitution mutations in the gene for coagulation factor VIII, procoagulant component (hemophilia A) (F8) account for approximately 50% of severe cases of hemophilia A (HA), and almost all moderate or mild cases. Because F8 is a large gene, mutation screening using denaturing HPLC or DNA sequencing is time-consuming and expensive. METHODS We evaluated high-resolut...

High FVIII:C levels have previously been shown to be an independent risk factor for thrombosis with 4.8 times higher potential risk of thrombosis in individuals with FVIII:C levels greater than 1.5 u/ml. Recently, we found that raised FVIII:C levels are largely attributable to elevated FVIII:Ag levels. The determinants of FVIII:Ag levels are unclear and might be partly genetic. The promoter of ...

Rheinheimera sp. strain F8 is a biofilm-forming gammaproteobacterium that has been found to produce large amounts of filamentous extracellular DNA. Here, we announce the de novo assembly of its genome. It is estimated to be 4,464,511 bp in length, with 3,970 protein-coding sequences and 92 RNA-coding sequences.

Ectopically expressed, human B-domainless (hB) factor 8 (F8) in platelets improves hemostasis in hemophilia A mice in several injury models. However, in both a cuticular bleeding model and a cremaster laser arteriole/venule injury model, there were limitations to platelet-derived (p) hBF8 efficacy, including increased clot embolization. We now address whether variants of F8 with enhanced activi...

Hemophilia A is an X-linked recessive bleeding disorder caused by defects in factor VIII gene (F8). Our study examines variations of single nucleotide polymorphism (SNP) in F8 in the Indian population and establishes the utility of a combination of SNP and microsatellite markers for the successful identification of carriers in the affected families.

Hemophilia A (HA) and B (HB) are estimated to affect 1 in 5,000 male births in the United States each year.[1] Inheritance of mutations in the Factor VIII (F8) gene or Factor IX (F9) gene causes these bleeding disorders. Identification of mutations causing a patient’s hemophilia can lead to better understanding of risk of complications [2], as well as aid in carrier detection in family members ...

Within the security architecture of the 3GPP system there is a standardised encryption mode f8 based on the block cipher KASUMI. In this work we examine the pseudorandomness of the block cipher KASUMI and the provable security of f8. First we show that the three round KASUMI is not a pseudorandom permutation ensemble but the four round KASUMI is a pseudorandom permutation ensemble under the ada...

Disease-causing alterations within the F8 gene were identified in 177 hemophilia A families of Portuguese origin. The spectrum of non-inversion F8 mutations in 101 families included 67 different alterations, namely: 36 missense, 8 nonsense and 4 splice site mutations, as well as 19 insertions/deletions. Thirty-four of these mutations are novel. Molecular modeling allowed prediction of the confo...
