Molecular and classical cytogenetic analyses demonstrate an apomorphic reciprocal chromosomal translocation in Gorilla gorilla [PDF]

open access: yes, 1992
The existence of an apomorphic reciprocal chromosomal translocation in the gorilla lineage has been asserted or denied by various cytogeneticists. We employed a new molecular cytogenetic strategy (chromosomal in situ suppression hybridization) combined ...

Comprehensive molecular cytogenetic analysis of the human blastocyst stage.

open access: yesHuman Reproduction, 2008
BACKGROUND The high frequency of chromosomal abnormalities observed in human gametes and embryos is unlike that seen in other mammalian species and is of great clinical significance, leading to high rates of pregnancy loss, and live-born children with ...

Mutation activity of Lonicera caerulea population in an active fault zone (the Altai Mountains) [PDF]

open access: yesarXiv, 2015
Geophysical and geochemical anomalies may have a mutagenic effect on plants growing in active fault zones being the factors of evolutionary transformation of plant populations. To test this assumption we evaluated the mutation activity of a Lonicera caerulea natural population in one of the active fault zones in the Altai Mountains.

Characterization of NAT, GST, and CYP2E1 Genetic Variation in Sub‐Saharan African Populations: Implications for Treatment of Tuberculosis and Other Diseases

open access: yesClinical Pharmacology &Therapeutics, Volume 117, Issue 5, Page 1338-1357, May 2025.
Tuberculosis (TB) is a major health burden in Africa. Although TB is treatable, anti‐TB drugs are associated with adverse drug reactions (ADRs), which are partly attributed to pharmacogenetic variation. The distribution of star alleles (haplotypes) influencing anti‐TB drug metabolism is unknown in many African populations.

Exploring the Multifractal Behavior of the Human Genome T2T-CHM13v2.0: Graphical Representations and Cytogenetics [PDF]

open access: yesarXiv
In this work, we applied the Chaos Game Representation (CGR) to the complete human genomic sequence T2T-CHM13v2.0, analyzing the entire chromosome assembly and each chromosome separately, including mitochondrial DNA. Multifractal spectra were determined using two types of box-counting coverage, revealing slight variations across most chromosomes. While

On High Dimensional Covariate Adjustment for Estimating Causal Effects in Randomized Trials with Survival Outcomes [PDF]

open access: yesarXiv, 2018
The purpose of this work is to improve the efficiency in estimating the average causal effect (ACE) on the survival scale where right-censoring exists and high-dimensional covariate information is available. We propose new estimators using regularized survival regression and survival random forests (SRF) to make the adjustment for the high dimensional ...
