Tall fescue and meadow fescue are naturally infected with fungal endophytes, Neotyphodiumcoenophialum and Neotyphodium uncinatum, respectively. Seed traits are an important measureof the effects of the endophytic fungi which has been less addressed. In this study we usedendophyte-infected (EI) and endophyte-free (EF) clones of tall and meadow fescue genotypes inthe field to investigate the effe...

Tall fescue toxicosis continues to be a major syndrome in temperate climates of the world in terms of economic loss to animal producers. Studies with forage-fed animals over the past three decades have provided insight concerning the pathophysiological effects of the alkaloids present in tall fescue [Lolium arundinaceum (Schreb.) DarbyshJ infected with the fungal endophyte Neotyphodium coenophi...

Natural forest succession on human-disturbed lands is often slow because the resources necessary for succession are depleted. In such landscapes, forest succession may be dependent on arrival of seeds from off-site, many of which are dispersed by fruiteating animals. We studied bat and bird seed dispersal in a deforested agricultural area adjacent to Kibale National Park, Uganda. Seed rain was ...

OBJECTIVE To determine the contribution of 7,8-methylenedioxylycoctonine (MDL)-type alkaloids to the toxic effects of tall larkspur (Delphinium spp) consumption in cattle. ANIMALS Sixteen 2-year-old Angus steers. PROCEDURES Plant material from 3 populations of tall larkspur that contained different concentration ratios of MDL-type-to-N-(methylsuccinimido) anthranoyllycoctonine (MSAL)-type a...

The human MHC nonrestricted cytotoxic T-cell line TALL-104 displays potent tumoricidal activity both in vitro and in animals bearing either spontaneous or induced tumors. In the present study, we used B6D2F1 mice engrafted with the syngeneic pre-B leukemia cell line 7OZ as a model system to investigate the mechanisms by which TALL-104 cells display antitumor activity in an immunocompetent host....

The human TALL-104 cell line is endowed with a uniquely potent M1H nonrestricted tumoricidal activity across several species. In view of the potential applicability of TALL-104 cells as an anticancer agent, this study was conducted to evaluate the possible toxicity and efficacy of this new cell therapy in a superior animal model with spontaneous tumors. Nineteen canine cases with advanced, refr...

lengthened gestation terms (Waller and Fribourg, 2002; Hemken et al., 1979). The U.S. economic loss in beef Cattle (Bos taurus) consuming tall fescue pastures infected with the associated with this endophyte was estimated at over endophyte Neotyphodium coenophialum often suffer physiological disorders that reduce animal performance. One solution is to replace $600 million annually (Hoveland, 19...

Background: Traditional serrated adenoma (TSA) features a unique serrated configuration because it involves two cell types: tall and short columnar cells. The serrated neoplasia pathway is related to the carcinogenesis of colorectal cancer. CpG island methylator phenotype-high (CIMP-high) is a unique genetic alteration in this pathway. Materials and Methods: This study investigated the prevalen...

Imprecise and vague information is part of our lives. Concepts like “tall”, “clever”, “fat” and others are imprecise since they can be used with slightly different meaning. Hence, we might use the concept tall to say that Paul is tall and Frank is tall. In this case someone could consider that Paul and Frank have the same height, fact that is not necessarily true. Similar problems occur in many...
