Psoroptes ovis, the causative agent of sheep scab, is an important ectoparasitic mite infecting sheep, goats and cattle. Infection is characterized by an extensive dermatitis, scab formation and intense itching. Initial focal lesions spread outwards, coalesce and may extend over the whole body. The host response to infestation has all the characteristics of(More)
The Rho-type GTPase Cdc42p is required for cell polarization and bud emergence in Saccharomyces cerevisiae. To identify genes whose functions are linked to CDC42, we screened for (i) multicopy suppressors of a Ts- cdc42 mutant, (ii) mutants that require multiple copies of CDC42 for survival, and (iii) mutations that display synthetic lethality with a(More)
The oxygenase domain of the mouse cytokine-inducible nitric-oxide synthase (iNOSox, amino acids 1-498) binds heme, tetrahydrobiopterin, and the substrate Arg and is the domain responsible for catalyzing nitric oxide synthesis and maintaining the enzyme's active dimeric structure. To further understand iNOSox structure-function, we carried out alanine point(More)
The human ovarian cancer cell line OV-MZ-19, established from a patient with cystadenocarcinoma of the ovary, expressing thrombomodulin (TM), a cell surface receptor for the serine protease thrombin, interacts with monoclonal and polyclonal antibodies having different specificity for TM. These antibodies detect TM antigen by means of flow cytofluorometry,(More)
