In a static frictionless transferable utilities bilateral matching market with systematic and idiosyncratic payo¤s, supermodularity of the match output function implies a strong form of positive assortative matching: The equilibrium matching distribution has all positive local log odd ratios or totally positive of order 2 (TP2). A particular form of a preference for own type implies supermodula...

The prognostic value of MRD in large series of childhood T-ALL has not yet been established. Trial AIEOP-BFM-ALL 2000 introduced standardized quantitative assessment of MRD for stratification, based on immunoglobulin and TCR gene rearrangements as polymerase chain reaction targets: Patients were considered MRD standard risk (MRD-SR) if MRD was negative at day 33 (time point 1 [TP1]) and day 78 ...

East Coast fever (ECF), caused by Theileria parva infection, is a frequently fatal disease of cattle in eastern, central and southern Africa, and an emerging disease in South Sudan. Immunization using the infection and treatment method (ITM) is increasingly being used for control in countries affected by ECF, but not yet in South Sudan. It has been reported that CD8+ T-cell lymphocytes specific...

Three semidominant, nonallelic mutations of maize, Teopod 1 (Tp1), Teopod 2 (Tp2) and Teopod 3 (Tp3), have a profound effect on both vegetative and reproductive development. Although each mutation is phenotypically distinct, they all (1) increase the number of vegetative phytomers; (2) increase the number of phytomers producing ears, tillers and prop roots; (3) increase the number of leaves bea...

AIM To evaluate the effects of tamoxifen citrate on gene expression during nuclear chromatin condensation in male rats. METHODS The effects of an oral dose of 0.4 kg/(kg.d) tamoxifen citrate on rates of in vitro chromatin decondensation, acridine orange (AO) dye uptake, concentration of thiol-groups, levels and/or expression of transition proteins 1, 2 (TP1, TP2), protamine 1 (P1), cyclic AMP...

We study the two-pion exchange potential at next-to-next-to-leading order in chiral effective field theory. We propose a new cut–off scheme for the pion loop integrals based on spectral function regularization. We show that this method allows for a consistent implementation of constraints from pion–nucleon scattering. It leads to a much improved description of the partial waves with angular mom...

BACKGROUND Immunity against the bovine protozoan parasite Theileria parva has previously been shown to be mediated through lysis of parasite-infected cells by MHC class I restricted CD8+ cytotoxic T lymphocytes. It is hypothesized that identification of CTL target schizont antigens will aid the development of a sub-unit vaccine. We exploited the availability of the complete genome sequence data...
