Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Pigmentary Mosaicism: An Overview

open access: yesJEADV Clinical Practice
Mosaicism refers to an individual who developed from a single fertilised egg but has two or more populations of cells with a different genotype as a result of a postzygotic mutation.

Cytogenetic abnormalities in a sample of females with premature ovarian failure

open access: yesMiddle East Fertility Society Journal, 2022
Background Premature ovarian failure (POF) is a complex heterogeneous disorder characterized by the triad of amenorrhea, hypergonadotropinism, and hypoestrogenism in women before the expected age of menopause.

Cross-Validation of Next-Generation Sequencing Technologies for Diagnosis of Chromosomal Mosaicism and Segmental Aneuploidies in Preimplantation Embryos Model

open access: yesLife, 2021
Detection of mosaic embryos is crucial to offer more possibilities of success to women undergoing in vitro fertilization (IVF) treatment. Next Generation Sequencing (NGS)-based preimplantation genetic testing are increasingly used for this purpose since ...

Genetic Normalization of Differentiating Aneuploid Human Embryos [PDF]

open access: yes, 2011
Early embryogenesis involves a series of dynamic processes, many of which are currently not well described or understood. Aneuploidy and aneuploid mosaicism, a mixture of aneuploid and euploid cells within one embryo, in early embryonic development are ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Genetic Mosaicism in Calmodulinopathy [PDF]

open access: yes, 2019
Background: CaM (calmodulin) mutations are associated with congenital arrhythmia susceptibility (calmodulinopathy) and are most often de novo. In this report, we sought to broaden the genotype-phenotype spectrum of calmodulinopathies with 2 novel ...

Maternal XX/X chromosome mosaicism in donor oocyte in vitro fertilization (IVF)

open access: yesMiddle East Fertility Society Journal, 2012
Objective: To evaluate if the degree of maternal X chromosome mosaicism is correlated to the pregnancy loss rate in donor oocyte IVF in women with a Turner syndrome mosaic (TS-Mosaic) diagnosis. Design: Prospective trial. Patients and methods: Women with

ON MOSAIC CRYSTALS

open access: yesProceedings of the National Academy of Sciences, 1929
Very little progress has been made during the last decade toward a theoretical understanding of the physical properties of matter in the solid state. The reasons for this stagnation are very clearly presented in a recent paper by A. Smekal.(1) According to Smekal, the properties of solids can be arranged in two large groups as follows.

Somatic mosaicism reveals clonal distributions of neocortical development

open access: yes, 2022
The structure of the human neocortex underlies species-specific traits and reflects intricate developmental programs. Here we sought to reconstruct processes that occur during early development by sampling adult human tissues.
