Phasing Gene Copies into Polyploid Subgenomes Using a Bayesian Phylogenetic Approach.
Freyman WA, Rothfels CJ. Freyman WA, et al. Methods Mol Biol. 2023;2545:123-138. doi: 10.1007/978-1-0716-2561-3_6. Methods Mol Biol. 2023. PMID: 36720810
This chapter describes the usage of homologizer to phase gene copies into polyploid subgenomes. Allopolyploids contain multiple copies of each genetic locus, where each copy potentially belongs to a different subgenome with its own distinct evolutionary history. If …

Efference copies: Side-eyeing across species.
Leary P, Schoppik D. Leary P, et al. Curr Biol. 2022 Jan 24;32(2):R91-R93. doi: 10.1016/j.cub.2021.12.002. Curr Biol. 2022. PMID: 35077698 Free article.
Efference copies of movement-inducing neural signals have been proposed to serve a role in gaze stabilization. Prior work has demonstrated a spino-extraocular motor circuit in the tadpole that relays copies of spinal commands to extraocular motor neurons. A recent s …

A method to calculate the number of dynamic HDFS copies based on file access popularity.
Cao XY, Wang C, Wang B, He ZX. Cao XY, et al. Math Biosci Eng. 2022 Aug 22;19(12):12212-12231. doi: 10.3934/mbe.2022568. Math Biosci Eng. 2022. PMID: 36653993 Free article.
HDFS heterogeneous clusters usually have multiple storage media at the same time. How to efficiently read and write file copies and reasonably use various storage media is a problem to be solved. Dynamically adjusting the number of copies is important in HDFS, which …

A population genetics theory for piRNA-regulated transposable elements.
Tomar SS, Hua-Van A, Le Rouzic A. Tomar SS, et al. Theor Popul Biol. 2023 Apr;150:1-13. doi: 10.1016/j.tpb.2023.02.001. Epub 2023 Mar 1. Theor Popul Biol. 2023. PMID: 36863578
Population genetics models have shown that TE copy numbers generally reach a limit, either because the transposition rate decreases with the number of copies (transposition regulation) or because TE copies are deleterious, and thus purged by natural selection. ...We …

Newborn Screening for SMA - Can a Wait-and-See Strategy be Responsibly Justified in Patients With Four SMN2 Copies?
Blaschek A, Kölbel H, Schwartz O, Köhler C, Gläser D, Eggermann K, Hannibal I, Schara-Schmidt U, Müller-Felber W, Vill K. Blaschek A, et al. J Neuromuscul Dis. 2022;9(5):597-605. doi: 10.3233/JND-221510. J Neuromuscul Dis. 2022. PMID: 35848034
However, there is no consensus in the SMA treatment community about early treatment initiation in patients with four copies of SMN2. OBJECTIVE: Approach to a responsible treatment strategy for SMA patients with four SMN2 copies detected in newborn screening. METHODS …

BACKGROUND: We aimed to investigate whether very low-level HIV-1 viraemia (VLLV) <20 copies/mL in HIV-1-infected patients on antiretroviral therapy (ART) whose VL was <20 copies/mL, was associated with a subsequent VL > 20 copies/mL. ...Each addition …
