Aneuploidy in spermatozoa in infertile men [PDF]
Background. An important problem is to investigate the frequency of aneuploidy in sperms of infertile men according to their changes in karyotype, that would allow to understand the contribution of paternal factor in the formation of chromosomal ...

22q11.2 DELETION SYNDROME: ALGORITHM FOR THE EARLY DIAGNOSIS AND TREATMENT
Chromosomal diseases, in particular microdeletions, determine the child's condition as well as the prognosis for a disease even at birth. With timely identified chromosomal abnormalities, we can diagnose not only obvious but also hidden disorders in the ...

Large scale chromosome folding is stable against local changes in chromatin structure [PDF]
Characterizing the link between small-scale chromatin structure and large-scale chromosome folding during interphase is a prerequisite for understanding transcription. Yet, this link remains poorly investigated. Here, we introduce a simple biophysical model where interphase chromosomes are described in terms of the folding of chromatin sequences ...

Catastrophic chromosomal restructuring during genome elimination in plants. [PDF]
Genome instability is associated with mitotic errors and cancer. This phenomenon can lead to deleterious rearrangements, but also genetic novelty, and many questions regarding its genesis, fate and evolutionary role remain unanswered.

Time Course of PR of UV-Induced Chromosomal Aberrations and Lethal Damage in G1 Xenopus Cells [PDF]
Synchronous cultures of early G1 cells were exposed to UV and their ability to photoreactivate lethal and aberrational damage was determined as a function of time following UV exposure.

The pattern of genomic gains in salivary gland MALT lymphomas
Background and Objectives Salivary gland mucosa-associated lymphoid tissue (MALT) lymphomas typically lack chromosomal translocations and the molecular genetics underlying their development is unknown. The aim of this study was to investigate chromosomal
