Ancestral environmental exposures to a variety of environmental toxicants and other factors have been shown to promote the epigenetic transgenerational inheritance of adult onset disease. The current study examined the potential transgenerational actions of the herbicide atrazine. Atrazine is one of the most commonly used herbicides in the agricultural industry, in particular with corn and soy ...
Environmental factors during fetal development can induce a permanent epigenetic change in the germ line (sperm) that then transmits epigenetic transgenerational inheritance of adult-onset disease in the absence of any subsequent exposure. The epigenetic transgenerational actions of various environmental compounds and relevant mixtures were investigated with the use of a pesticide mixture (perm...
The duration of blood feeding by similar-sized Aedes aegypti (L.) was determined under laboratory conditions in Trinidad, West Indies. Ae. aegypti from the F0 generation contained individuals that fed quickly (106.2 seconds) as well as slowly (330.0 seconds). Among the fast feeders (<2 min), the time taken for blood feeding during the first gonotrophic cycle was much shorter than that observed ...
BACKGROUND AND RATIONAL Telaprevir-based therapy (TBT) has been extensively evaluated in clinical trials. So we designed a study to compare the efficacy and safety of TBT between patients with moderate fibrosis and those suffering from advanced fibrosis in clinical practice. A multicenter observational and ambispective study was conducted. It included 582 patients with chronic hepatitis C genot...
Background: Epidemiological studies indicate increased risk of leukemia, lymphoma, and brain tumor among electrical workers exposed to electromagnetic fi eld (EMF). Other investigator reported that continuous exposure of four successive generations of mice to EMF in doses of 1 kV to 5 kV caused tumor formation in offspring. The objective of this study was to evaluate the effect of continuous ex...
________________________________________________________________________________________________________ F2/F3 of voiced plosives and F1/F2 of vowel in VCV Sequences in Children with a Cleft Palate-An acoustic Study The aim of this acoustic study is to examine place of articulation during the production of voiced plosives by children with a cleft palate. The data are compared with those obtaine...
Breeding programs strategies depends on genetical mechanism of selection traits. In the present research, generation mean analysis with joint scaling test was performed to determine the gene action. F1, F2 and F3 generations, derived from Roushan and Kavir cross along with their parents were sown in a partial Lattice design with two replications under stress condition at the research field of S...
An important aspect of speech perception is the ability to group or select formants using cues in the acoustic source characteristics--for example, fundamental frequency (F0) differences between formants promote their segregation. This study explored the role of more radical differences in source characteristics. Three-formant (F1+F2+F3) synthetic speech analogues were derived from natural sent...
Two experiments were conducted to test the hypothesis that higher formant normalization results from the auditory integration of F2 and F3 when they are within 3 Bark of each other. In the first experiment, Formants 3-5 were manipulated in both a "hid"-"head" continuum (in which F2 and F3 are within 3 Bark of each other) and a "hood"-"HUD" continuum (in which F2 and F3 are not within 3 Bark of ...
Objective: To measure the efficiency of using advanced generations some commercial tomato hybrids for small farmers and to identify most important yield components associated with yield. Design/Methodology/Approach: Seven saladette-type indeterminate growth were evaluated, as well their respective F2s F3s under greenhouse conditions. The evaluation three was carried out during 2013 agricultural...
