In Chile, interspecific hybrids between Eucalyptus nitens × globulus (GloNi) were developed by Arauco Forestry to capture specific traits from each parental species: growth rate and cold resistance E. (NIT) wood properties (GLO). Field tests of distributed in two geographic zones: (12 tests) Valdivia (15 tests), where measurements recorded at different ages. The hybrid population is composed cl...

Background: Radon and thoron are invisible, odorless, heavy and radioactive gases which are ubiquitously present in dwellings and in the environment. In the present work, seasonal variation of indoor radon, thoron and their progeny concentrations has been studied in the dwellings of industrially polluted cities in District Faridabad, Haryana and District Mathura in Uttar Pradesh. Materials and ...

This pilot study reports the vertical transmission and reverse thermosensitivity of MS-H vaccine strain Mycoplasma synoviae (MS) by RAPD in commercial breeders their progeny. At two weeks age, were vaccinated with ts+ strain. 9 an outbreak infectious synovitis (IS) was detected Tracheal swab samples collected from at 24, 39, 48, 70 age. weeks, pullets elbow joints collected. performed on isolat...

The relationships between reproduction and aging are important for understanding the mechanisms of aging and evaluating evolutionary theories of aging. To investigate the effects of progeny production on reproductive and somatic aging, we conducted longitudinal studies of Caenorhabditis elegans hermaphrodites. For mated wild-type animals that were not sperm limited and survived past the end of ...

Although interest in beef-on-dairy breeding strategies is intensifying, little actually known of the performance differences between beef-sired male and female progeny dairy cows. The objective was therefore to use a large cross-sectional database up 1,389,670 animals investigate if existed generated from matings; focus on characteristics both producer (i.e., gestation length, calving performan...

Abstract The use of probiotics in swine production may be an alternative to antibiotics for both disease prevention and growth promotion. Limited data exist on their potential modulate offspring immune function when fed solely the dam. A study was designed assess immunomodulatory effect maternal supplementation Saccharomyces cerevisiae var. boulardii (scb) from gestational day 84 until end lact...

Background: Decay products of radon and thoron present in indoor environment are the most important sources of radiation from natural sources which affect human beings, since general public spend at lest 80% of their time in indoor. Materials and Methods: Air samples were collected for measuring the concentration of radon and thoron daughter products from various indoor environments d...

A two-screen sampler (an effective dosimeter), with a collection efficiency matched to the particle size response of the radon progeny dose conversion factors (DCF), obtained from the ICRP respiratory tract model as implemented in the computer code RADEP, has been developed to assess the inhalation dose from exposure to radon progeny. In order to evaluate the performance of this sampler, the se...

OBJECTIVES Methylmercury (MeHg) and polychlorinated biphenyls (PCBs) are ubiquitous environmental pollutants. Both are neurotoxic, especially for the developing brain. The main source of human exposure to MeHg and PCBs is seafood. The aim of the present work was to find out whether and how separate or combined perinatal exposure to these neurotoxicants affects neurobehavioural functions in matu...
