The lack of naturalness hampers the widespread application of speech synthesis. Increasing the size of the unit database in a concatenative speech synthesizer has been proposed as a method to increase the variety of units—thereby improving naturalness. However, expanding the unit database increases the computational cost of selecting the most appropriate unit and compounds the risk that a perce...

We have investigated the capacity of vaginal and uterine epithelia (VE and UE) to reexpress normal morphology and hormone responsiveness following cell culture. VE and UE from adult ovariectomized mice were grown in a collagen gel matrix with serum-free medium for 7-10 days. Proliferation of these cells occurs in the absence of 17 beta-estradiol and is not stimulated by 17 beta-estradiol; the V...

INTRODUCTION Differentiating between cross-reactivity and double sensitization is still a challenging issue in allergology. AIM To differentiate cross-reactions accompanying latex allergy with the use of the ISAC test. MATERIAL AND METHODS Thirty-nine patients reporting immediate allergic reactions to latex were enrolled into the study (group A). The control group was comprised of 41 patien...

MAGIC populations represent one of a new generation of crop genetic mapping resources combining high genetic recombination and diversity. We describe the creation and validation of an eight-parent MAGIC population consisting of 1091 F7 lines of winter-sown wheat (Triticum aestivum L.). Analyses based on genotypes from a 90,000-single nucleotide polymorphism (SNP) array find the population to be...

Fetal breathing movements play an important role in normal fetal lung growth. We have previously shown that an intermittent mechanical strain regimen (60 cycles/min, 15 min/h), simulating normal fetal breathing movements, stimulated growth of mixed fetal rat lung cells in organotypic culture. In the present study, we examined the individual responses of the two major fetal lung cell types, fibr...

Conditional gene targeting uses the insertion of expression cassettes for the selection of targeted embryonic stem cells. The presence of these cassettes in the final targeted chromosomal locus may affect the normal expression of the targeted gene and produce interesting knock down phenotypes. We show here that the selection cassette may then be selectively removed in vivo, using three appropri...

Myc is an essential regulator of cell growth and proliferation. Myc overexpression promotes the homeostatic expansion of cardiomyocyte populations by cell competition, however whether this applies to other cardiac lineages remains unknown. The epicardium contributes signals and cells to the developing and adult injured heart and exploring strategies for modulating its activity is of great inter...

Transgene expression from short promoters in transgenic animals can lead to unwanted transgene expression patterns, often as a byproduct of random integration of the expression cassette into the host genome. Here I demonstrate that the often used PB-Cre4 line (also referred to as "Probasin-Cre"), although expressing exclusively in the male prostate epithelium when transmitted through male mice,...

In this study, we examined the role of the hippocampus in relational memory by comparing item recognition performance in amnesic patients with medial temporal lobe (MTL) damage and their matched controls. Specifically, we investigated the contribution of associative memory to item recognition using a cued recognition paradigm. Control subjects studied cue-target pairs once, whereas amnesic pati...

The ret finger protein (rfp) is a member of the B box zinc finger gene family which possesses a tripartite motif consisting of a RING finger, B box finger, and a coiled-coil domain. Rfp is expressed at specific stages of spermatogenesis and in various adult mouse and human tissues. It becomes oncogenic when the tripartite domain is recombined with the tyrosine kinase domain of the ret protoonco...
