The effect of genotype, sex and hatch on carcass traits and physical characteristics of eggs was investigated in the Japanese quail. Two strains of Japanese quails including the White (P1) and Wild (P2) genotypes were chosen as the parental generation and crossed reciprocally (10 singlepair mating) to create the F1 progeny. The F1 birds (27 males and 81 females) were mated randomly to produce t...

Nerve growth factor (NGF) controls the growth of sympathetic nerves and is increased in young spontaneously hypertensive rats (SHR). The NGF gene has been linked genetically with hypertension in the SHR strain and may explain high NGF mRNA levels. To test for genetic linkage between the NGF gene and its expression in vivo, we examined renal NGF mRNA levels in male SHR, control Donryu rats (DRY)...

The geodynamic evolution of the Mesoproterozoic Karagwe-Ankole Belt, situated in Central Africa, is largely unconstrained and topic discussion. To overcome this knowledge gap, tectonic history Western Domain has been studied, focusing on bedding, foliations lineations, quartz vein generations from Kibuye-Gitarama-Gatumba area (West Rwanda). results our study reveal two fold generations, that ar...

INTRODUCTION SWITCHING SEQUENCE A single resistor on-load tap changer comprising fixed contacts F1 and F2, transitional arcing contact T, main arcing contact M and bridging resistor R is shown in Fig. 1. A command initiates the switching operation from normal running position 1 to position 2, such that contact T starts to move left towards contact F2 (Fig. 1a). As T approaches F2 a recovery v...

BACKGROUND Ancestral environmental exposures to a variety of environmental factors and toxicants have been shown to promote the epigenetic transgenerational inheritance of adult onset disease. The present work examined the potential transgenerational actions of the insecticide dichlorodiphenyltrichloroethane (DDT) on obesity and associated disease. METHODS Outbred gestating female rats were t...

Similar to the multi-hit theory of schizophrenia, social behavior pathologies are mediated by multiple factors across generations, likely acting additively, synergistically, or antagonistically. Exposure to social adversity, especially during early life, has been proposed to induce depression symptoms through immune mediated mechanisms. Basal immune factors are altered in a variety of neurobeha...

Ramulosis is one of the most aggressive diseases in cotton, and understanding the genetic control of its resistance is imperative for selecting superior cotton genotypes in breeding programs. This study analyzed the inheritance pattern of this resistance using chi-square goodness-of-fit tests to determine the phenotypic proportions of the F2 generation, and a mixed inheritance approach to joint...

Analgesics which affect prostaglandin (PG) pathways are used by most pregnant women. As germ cells (GC) undergo developmental and epigenetic changes in fetal life and are PG targets, we investigated if exposure of pregnant rats to analgesics (indomethacin or acetaminophen) affected GC development and reproductive function in resulting offspring (F1) or in the F2 generation. Exposure to either a...

Experiments were carried out to test the susceptibility of Biomphalaria tenagophila to the infection with strain SJ of Schistosoma mansoni in the F1, F2 and non-selected parental generation. The potential adaptation of B. tenagophila to desiccation, in healthy mollusks and those exposed to the larvae of S. mansoni of the F1, F2 and non-selected parental generations was also studied. The presenc...

Maternal protein restriction causes metabolic alterations associated with hypothalamic dysfunction. Because the consequences of metabolic programming can be passed transgenerationally, the present study aimed to assess whether maternal protein restriction alters the expression of hypothalamic neuropeptides in offspring and to evaluate hormonal and metabolic changes in male offspring from the F1...
