Membrane invagination induced by Shiga toxin B-subunit: from molecular structure to tube formation.

open access: yesSoft Matter, 2016
The bacterial Shiga toxin is composed of an enzymatically active A-subunit, and a receptor-binding homopentameric B-subunit (STxB) that mediates intracellular toxin trafficking.

The C. elegans LIM homeobox gene lin-11 specifies multiple cell fates during vulval development [PDF]

open access: yes, 2003
LIM homeobox family members regulate a variety of cell fate choices during animal development. In C. elegans, mutations in the LIM homeobox gene lin-11 have previously been shown to alter the cell division pattern of a subset of the 2° lineage vulval ...

From Invaginating Site to Deep Lesion: Spatial Transcriptomics Unravels Ectopic Endometrial Penetration Features in Adenomyosis

open access: yesAdvanced Science
Adenomyosis, characterized by clinical intractability, significantly impacts female fertility and life quality due to the absence of definitive diagnostic markers and effective treatment options.

Evaporation Caused Invaginations of Acoustically Levitated Colloidal Droplets

open access: yesNanomaterials, 2022
Controlled buckling of colloidal droplets via acoustic levitation plays an important role in pharmaceutical, coating, and material self-assembly. In this study, the evaporation process of PTFE colloidal droplets with two particle concentrations (60 wt ...

The Amphioxus SoxB Family: Implications for the Evolution of Vertebrate Placodes [PDF]

open access: yes, 2007
Cranial placodes are regions of thickened ectoderm that give rise to sense organs and ganglia in the vertebrate head. Homologous structures are proposed to exist in urochordates, but have not been found in cephalochordates, suggesting the first chordates

Epithelial stratification and placode invagination are separable functions in early morphogenesis of the molar tooth

open access: yesDevelopment, 2016
Ectodermal organs, which include teeth, hair follicles, mammary ducts, and glands such as sweat, mucous and sebaceous glands, are initiated in development as placodes, which are epithelial thickenings that invaginate and bud into the underlying ...

APPENDICULAR INVAGINATION DUE TO ENDOMETRIOSIS

open access: yesZdravniški Vestnik, 2003
Background. Invagination of the vermiform appendix is a very rare occurrence. We summarize epidemiologic and etiologic factors, types of classification, symtomatology, diagnostic features and treatment.Patients and treatment. The authors present 49-years

A Massive Colorectal Lipoma Prolapsed with Invagination Through Anal Canal: Case Report

open access: yesTurkish Journal of Colorectal Disease, 2017
Colorectal lipoma is a rare and generally asymptomatic lesion of the colon. Symptoms emerge as the lipoma grows in size. We here describe our diagnosis and management of a case presenting with abdominal pain, rectal bleeding, and protruding rectal mass ...

Invagination of Ectodermal Placodes Is Driven by Cell Intercalation-Mediated Contraction of the Suprabasal Tissue Canopy

open access: yesPLoS Biology, 2016
Ectodermal organs such as teeth, hair follicles, and mammary glands begin their development as placodes. These are local epithelial thickenings that invaginate into mesenchymal space.

A stochastic model of Min oscillations in Escherichia coli and Min protein segregation during cell division

open access: yes, 2005
The Min system in Escherichia coli directs division to the centre of the cell through pole-to-pole oscillations of the MinCDE proteins. We present a one dimensional stochastic model of these oscillations which incorporates membrane polymerisation of MinD
