Predictors of fear of recurrence in patients one year after cancer rehabilitation: a prospective study.

Background: Fear of cancer recurrence (FCR) or cancer progression is one of the most frequent distressing psychological symptoms in cancer patients. In contrast to anxiety disorders according to the ICD-10 or DSM-IV, FCR describes an emotional response to the real threat of a life-threatening illness. Elevated levels of FCR can become dysfunctional, causing considerable disruption in social functioning, and affect well-being and quality of life (QoL).

Genetic characterization of Toxoplasma gondii in wildlife from Alabama, USA.

The genetic diversity of Toxoplasma gondii circulating in wildlife is of interest to understand the transmission of this parasite in the environment. In the present study, we genetically characterized five T. gondii isolates from different wild animals including two isolates from a bobcat (Lynx rufus), one from a red-shouldered hawk (Buteo lineatus), one from a white-tailed deer (Odocoileus virginianus), and one from a bald eagle (Haliaeetus leucocephalus).

Inactivation of Giardia lamblia cysts by cobalt-60 irradiation.

Cysts of Giardia lamblia can be a contaminant of water and food that can infect humans and cause the zoonotic disease giardiasis. Irradiation by a cobalt-60 source was investigated for its ability to inactivate cysts such that they would not be infective to gerbils. Cysts that received doses of radiation ranging from 0.

Phosphorus-bearing axially chiral biaryls by catalytic asymmetric cross-cyclotrimerization and a first application in asymmetric hydrosilylation.

A novel and efficient, two-step route to axially chiral biaryls is demonstrated. In a direct asymmetric cross-cyclotrimerization in the presence of a chiral cobalt(I) catalyst, axially chiral biaryls bearing phosphoryl moieties have been prepared, and through indirect evidence the authors have been able to clarify the origin of the stereochemical induction and the nature of the central intermediate in the catalytic cycle. By subsequent reduction of the phosphoryl moiety to the corresponding phosphine, a very efficient and atom-economical approach to chiral systems has been developed.
