The possibility that the Peromyscus maniculatus complex of deer mice arose via the process described as "centrifugal speciation" (Brown, 1957) has been discussed by Bowers et a l . , 1973, Lawlor, 1974, Baker et al., 1975, and Greenbaum et a l . , 1978. This study was designed to yield additional da ta on the cytogenetics of three species of this complex in order to evaluate the "centrifugal sp...

Aim. Fertility disorders are one of the most common problems reproductive medicine. Chromosomal abnormalities play a crucial role in failure. The main purpose our study was to determine types and frequency chromosomal aberrations couples with history infertility. Methods. Karyotyping performed 652 failure between 2004 2022, including 203 primary infertility (PI), 240 recurrent pregnancy loss (R...

In this study the nature of chromosomal proteins, his tones and nonhistone in resident alveolar macrophages was investigated in comparison to peritoneal neutrophils and calf thymus proteins. Cells were obtained by lavaging the lung and after purity determination they were subjected to fractional extraction procedures. Proteins were then analysed on SDS polyacrylamide gels and densitometric...

Not to be confused with... CENP-E, chromokinesin, Polo kinase... A number of proteins are localised a bit like chromosomal passengers. However these proteins occupy slightly different locations on the chromosomes: the kinetochore for CENP-E and Polo; all along the chromosome arms for chromokinesin. Some of these proteins may interact functionally or physically with the passenger proteins. Stran...

the frequency of chromosomal aberrations was studied in the peripheral blood lymphocytes of 65 radiology technologists crt) working at hospitals chronically exposed to x-rays. although film dosimetry did not show the maximal annual permitted dose in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal aberrations in r t compared to unexposed controls. th...

abstract: colorectal cancer (crc) is the third most common cancer in men and the second most common cancer in women worldwide. both genetic and epigenetic alterations are common in crc and are the driving force of tumorigenesis. chromosomal instability, microsatellite instability and cpg island methylator phenotype pathways are responsible for genetic instability in colorectal cancer. chromosom...

Growth and development in humans begin at conception, which shows progress interdependence. Normal children show the characteristic of growth development. In with disorder, chromosomal abnormality may be found. This study aimed to determine patients disorder. The samples were taken from karyotype results Medical Genetics Laboratory, Faculty Medicine, Universitas Wijaya Kusuma Surabaya, 2010-202...

Trematomus species (suborder Notothenioidei; family Nototheniidae) are widely distributed in the southern oceans near Antarctica. There 11 recognized genus Trematomus, and notothenioids known to have high chromosomal diversity (2n = 24–58) because of relatively recent rapid adaptive radiation. Herein, we report chromosomal-level genome assembly T. loennbergii, first characterized representative...

background: embryo morphology has been proposed as an alternative marker of chromosomal status. the objective of this retrospective cohort study was to investigate the association between the chromosomal status on day 3 of embryo development and blastocyst morphology.embryo morphology has been proposed as an alternative marker of chromosomal status. the objective of this retrospective cohort st...
