Prenatal exposure to marijuana has been associated with a variety of brain deficits, as Δ9-tetrahydrocannabinol (THC), its main active ingredient crosses the placenta and affects foetal brain development. Despite this effect, marijuana remains a commonly abused substance among pregnant women. In the current study, we examined the histological and biochemical changes in the superior colliculus (...

Several measures of life cycle cow efficiency were calculated using weights and individual feed consumptions recorded on 160 dams of beef, dairy and beef X dairy breeding and their progeny. Ratios of output to input were used to estimate efficiency, where outputs included weaning weights of progeny plus salvage value of the dam and inputs included creep feed consumed by progeny plus feed consum...

Attack rates, progeny production, sex ratios, and host use efÞciency of Muscidufurax raptor Girualt and Sanders, Spalangia cameroni Perkins, S. endius (Walker), S. nigroaenea Curtis, S. gemina Boucek (Hymenoptera: Pteromalidae), and Dirhinus himalayanus (Hymenoptera: Chalcididae)were evaluated in laboratory bioassayswith Þve dipteran hosts: house ßy (Musca domesticaL.), stable ßy (Stomoxys calc...

Common bean is a worldwide important crop. The development of varieties with durable resistance to diseases major challenge in common breeding. present study aimed at evaluating the phenotypic and molecular selection anthracnose population obtained by assisted backcrossing from IAC Formoso (resistant, donor parent) × BRS Pérola (susceptible, recurrent parent). Nine microsatellites (SSRs) one Se...

Background: The variation of the radon progeny concentration in outdoor environment and meteorological parameters at fine resolution were studied for one year at a continental location, National Atmospheric Research Laboratory, Gadanki, India.  Materials and Methods: The concentrations were measured using Alpha Progeny Meter by collecting air samples at a height of 1 m above the Earth&rsqu...

Tree fruit breeding is an inherently long-term process. The average generation time can range from 2 to 20 years depending on the species. While the production of large numbers of progeny favors the appearance of rare but desired recombinants, large tree size limits the number of progeny that can be planted and maintained. Significant genotype x environment interactions require multiple test si...

We tested whether the pairing of selected isolates could be used to increase the efficiency of a decay fungus Chondrostereum purpureum (Pers. Ex Fr.) Pouzar to control hardwood sprouting in Finland. We paired C. purpureum strains efficient in sprout control or highly active in laccase production, and tested the efficacy of their progeny in spout control experiments. This procedure resulted in a...
