The effect of radiation on the long term productivity of a plant based CELSS [PDF]
Mutations occur at a higher rate in space than under terrestrial conditions, primarily due to an increase in radiation levels. These mutations may effect the productivity of plants found in a controlled ecological life support system (CELSS).

A survey of chromosome anomalies in Malta [PDF]
, 1989 433 individuals referred for chromosome analysis between 1983 and 1987 were included in the survey. Among individuals with dysmorphic features or congenital anomalies 42% of babies referred in the neonatal period and 12 to 30% of individuals in older age

Karyotype, ploidy, and gene dosage [PDF]
WormBook, 2005 The normal karyotype of Caenorhabditis elegans, with its five pairs of autosomes and single pair of X chromosomes, is described. General features of chromosomes and global differences between different chromosomal regions are discussed. Abnormal karyotypes, including duplications, deficiencies, inversions, translocations and chromosome fusions are ...

Demographic history of the Malayan tapirs (Tapirus indicus) in Southeast Asia
Ecological Research, EarlyView.Malayan tapirs in Southeast Asia can be distinguished into 3 geographical groups, based on genetic structure analysis in 11 whole genomes. The effective population size (Ne) of tapirs shows a general decreasing trend, as suggested by the pairwise sequentially Markovian coalescent analysis, with population expansion or structuring during late Early ...

Plant Species Biology, EarlyView.Hybrids vulnerable to drought may increase postzygotic isolation in hybrid zones. Drought experiments can reveal the influence of climate change on hybrid zones. Crassulacean acid metabolism in parental species and hybrids was negatively affected by drought.

PLoS ONE, 2013 Reproductive interactions among cytotypes in their contact zones determine whether these cytotypes can co-exist and form stable contact zones or not. In autopolyploids, heteroploid cross-compatibilities might depend on parental ploidy, but tests of this ...

Integrative Zoology, EarlyView.To monitor populations of an endangered species such as Galemys pyrenaicus in the Extremadura area, qPCR techniques have been used to determine sex, using non‐invasive sampling techniques. ABSTRACT Desmans belong to the subfamily Desmaninae, which are members of the family Talpidae.

Interventional oncology in children: Where are we now?
Journal of Medical Imaging and Radiation Oncology, EarlyView.Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...

The Effect of Assisted Reproductive Technologies on Human Sex Ratios
Australian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.ABSTRACT Background Modern assisted reproductive technology (ART), including pre‐implantation genetic testing for aneuploidy (PGT‐A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.
