Heterophase Polymorph of TiO (Anatase, Rutile, Brookite, TiO (B)) for Efficient Photocatalyst: Fabrication and Activity.

TiO exists naturally in three crystalline forms: Anatase, rutile, brookite, and TiO (B). These polymorphs exhibit different properties and consequently different photocatalytic performances. This paper aims to clarify the differences between titanium dioxide polymorphs, and the differences in homophase, biphase, and triphase properties in various photocatalytic applications.

The impact of hepatitis C virus viremia on renal graft and patient survival: a 9-year prospective study.

Background: The impact of hepatitis C virus (HCV) infection on long-term patient and renal graft survival is controversial.

Methods: We prospectively followed up for approximately 9 years 133 hepatitis B surface antigen (HBsAg)-negative successive renal transplant recipients for whom HCV RNA polymerase chain reaction (PCR) results were available before transplantation. We compared graft and patient survival rates and causes of death and graft failure in PCR-positive and PCR-negative transplant recipients.

Effect of anti-schistosomal treatment on schistosomal hepatic pathology: an experimental study in Syrian golden hamsters.

Thirty Syrian golden hamsters were infected with Schistosoma mansoni and 10 were used as negative controls. Hamsters were infected by 100 cercariae; 15 were treated by praziquantel in doses of 100 mg/kg at 12, 13, 14 and 15 weeks postinfection, and 15 hamsters were left as positive control. Five from each subgroup were sacrificed at 24, 28 and 32 weeks after infection.
