Karyotype, sex determination, and meiotic chromosome behavior in two pholcid (Araneomorphae, Pholcidae) spiders: implications for karyotype evolution. [PDF]

PLoS ONE, 2011
There are 1,111 species of pholcid spiders, of which less than 2% have published karyotypes. Our aim in this study was to determine the karyotypes and sex determination mechanisms of two species of pholcids: Physocyclus mexicanus (Banks, 1898) and ...

Visualizing dimensionality reduction of systems biology data

, 2012
One of the challenges in analyzing high-dimensional expression data is the detection of important biological signals. A common approach is to apply a dimension reduction method, such as principal component analysis. Typically, after application of such a

Hetrombopag Added to Cyclosporine as the First‐Line Treatment for Patients With Non‐Severe Aplastic Anemia: A Phase 2 Multicenter Trial

American Journal of Hematology, EarlyView.
ABSTRACT Non‐severe aplastic anemia (NSAA) is a heterogeneous bone marrow failure syndrome with limited standardized treatment options. Cyclosporine A (CsA) monotherapy often yields suboptimal responses, highlighting an unmet clinical need for more effective therapies.

Rates of karyotype evolution in placental mammals [PDF]

Hereditas, 2009
The genera of eutherian mammals have been divided into two groups depending on whether the animals in the genera have high or low rates of karyotype evolution. The rate of karyotype evolution in a genus is estimated by the standard deviation of the chromosome numbers within the genus.

A Systematic Review and Meta‐Analysis of the Birth Prevalence of Turner Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Turner syndrome, a chromosomal disorder, causes short stature, pubertal arrest, amenorrhea, and infertility in females. Prevalence estimates vary widely; however, reliable estimates are important for public health initiatives. Therefore, a meta‐analysis was undertaken.

Cytogenetic and comparative morphology of two allopatric populations of Astyanax altiparanae Garutti & Britski, 2000 (Teleostei: Characidae) from upper rio Paraná basin

Neotropical Ichthyology
The recently described fish species, Astyanax altiparanae (tetra) is common in the upper rio Paraná basin, and has been reported in the Iguaçu basin. However, its natural origin in the rio Iguaçu is questionable.

Comparative chromosome band mapping in primates byin situ suppression hybridization of band specific DNA microlibraries [PDF]

, 1991
A DNA-library established from microdissected bands 8q23 to 8q24.1 of normal human chromosomes 8 (Lüdecke et al., 1989) was used as a probe for chromosomal in situ suppression (CISS-) hybridization to metaphase chromosomes of man and primates including ...

Chromosomal variation among populations of a fungus-farming ant: implications for karyotype evolution and potential restriction to gene flow

BMC Evolutionary Biology, 2018
Intraspecific variation in chromosome structure may cause genetic incompatibilities and thus provides the first step in the formation of species. In ants, chromosome number varies tremendously from 2n = 2 to 2n = 120, and several studies have revealed ...

Chromosomal differentiation among bisexual European species of Saga (Orthoptera: Tettigoniidae: Saginae) detected by both classical and molecular methods

European Journal of Entomology, 2009
We report the karyotype characteristics including chromosome numbers of Saga campbelli campbelli, S. c. gracilis, and S. rammei using the following classical cytogenetic methods: C-banding, silver staining, and fluorochrome staining DAPI and CMA3.
