Genetic causes have a considerable involvement in infertility. Well-known examples are some chromosomal translocations or sex-chromosomal abnormalities and Y-chromosome deletions. The most common chromosomal aberrations associated especially with severe oligo- and azoospermia are sex chromosome aneuploidies and chromosomal translocations. Consequently, occurrence of aneuploid embryos will lower...

Abstract The success of translocation as a management tool is based on reversing the factors that led to population becoming threatened or locally extinct. We assessed whether translocating jaguar Panthera onca into surroundings protected area in Brazilian Atlantic Forest with resident was effective. captured male an urban where there were no substantiated previous records jaguars. In capture o...

hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (vi) or chromium nitrate chromium (iii). although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (iii) than those in chromium (vi), majority being in...

Wheat streak mosaic virus (WSMV) is a mite-vectored with substantial economic impact on wheat production. One of the effective sources resistance to WSMV, Wsm1, carried translocation from Thinopyrum intermedium. The original whole arm form this (T4DL·4JsS) was highly against WSMV but yield penalty in absence virus. Shorter recombinants Th. intermedium are now available. This study characterized...

We have previously developed technology for multiplexing probes for the detection of transcription of many genes simultaneously within single cells. This has allowed us to determine the spatial localization of multiple genes with respect to each other in the nucleus, and ultimately the expression profile of the cell with respect to surrounding cells in a tissue. Six parameters of transcriptiona...

ETEROZYGOUS autosomal translocations have been shown to affect recomHbination in the X chromosome in various ways (HINTON 1965); translocations with long interstitial distances increased recombination in X, those with short interstitial distances decreased recombination in X, and those with intermediate interstitial distances had little or no effect. Other incidental tests of translocation hete...

The aim of this study was to identify genetic covariants for fundamental measures of brain function (event-related potentials (ERPs): P300 latency and slow wave amplitude recorded in a working-memory task) and more complex cognitive measures (behavioral non-ERP measures: working-memory performance, information processing speed, IQ). Data were collected from 252 monozygotic and 297 dizygotic twi...

Recent field experiments demonstrated the possibility of using the sterile male method for the control of Anopheles albimanus Wiedemann, the most important vector of human malaria in Central America. Until now there was no practical method for excluding females from the releases of sterile males. A genetic method was developed for the preferential elimination of females during any of the four l...
