FEBS 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 ...

The Visual Computer, 2006 This paper considers the problem of placing mosaic\ud tiles on a surface to produce a surface mosaic. We assume\ud that the user specifies a mesh model, the size of the\ud tiles and the amount of grout, and optionally, a few control\ud vectors at key locations on the surface indicating the\ud preferred tile orientation at these points.

Cytogenetic abnormalities in a sample of females with premature ovarian failure
Middle 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.

Life, 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 ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

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

Multi‐tissue cytogenetic analysis for the diagnosis of mosaic Down syndrome: A case report
Clinical Case Reports, 2022 Less than one percent of individuals with Down syndrome exhibit mosaicism, a biological phenomenon that describes an individual who has two or more genetically distinct cell lines.

The photoreceptor mosaic [PDF]
Eye, 1998 The organisation of the human photoreceptor mosaic reflects evolutionary strategies for optimising visual information under a wide range of stimulus conditions: (1) The rod population dominates (max. 170,000/mm2 at c. 30 degrees sup.) except for the central 2 degrees and along the ora serrata.
