Chemically Defined Organoid Culture System for Cholangiocyte Differentiation [PDF]

open access: yes
Cholangiocyte organoids provide a powerful platform for applications ranging from in vitro modeling to tissue engineering for regenerative medicine. However, their expansion and differentiation are typically conducted in animal-derived hydrogels, which ...

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Assessing the Physical and Immune Response of Intestinal Organoids for Necrotizing Enterocolitis using NEC-in-a-Dish [PDF]

open access: yes, 2023
Necrotizing enterocolitis (NEC) is a devastating disease that impacts the intestinal tract, which most commonly occurs in preterm infants. Its pathogenesis is unknown, but previous studies have found that an alteration in the intestinal microbiome, in ...

The Aging Blood: Cellular Origins, Circulating Drivers, and Therapeutic Potential

open access: yesAging and Cancer, EarlyView.
As a conduit linking all organs, the blood system both reflects and actively drives systemic aging. This review highlights how circulating pro‐aging and antiaging factors and age‐associated hematopoietic stem cell dysfunction contribute to immunosenescence and multi‐organ decline, positioning the hematopoietic system as a target for aging intervention.

Single- versus two-visit pulpectomy treatment in primary teeth with apical periodontitis: A double-blind, parallel group, randomized controlled trial

open access: yesJournal of Indian Society of Pedodontics and Preventive Dentistry, 2016
Context: Reduction of the bacterial populations to levels compatible with periradicular tissue healing is the primary microbiological goal of the endodontic treatment of teeth with apical periodontitis.

Development of a New 3D Hybrid Model for Epithelia Morphogenesis

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Many epithelial developmental processes like cell migration and spreading, cell sorting, or T1 transitions can be described as planar deformations. As such, they can be studied using two-dimensional tools and vertex models that can properly predict ...

Engineering a microwell duct-on-chip technology to translate exocrine pancreatic organoids to a cancer model [PDF]

open access: yes, 2022
Das duktale Adenokarzinom der Bauchspeicheldrüse (PDAC) ist eine der tödlichsten Erkrankungen der exokrinen Bauchspeicheldrüse, für die uns relevante Frühdiagnosemarker fehlen.

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Rebalancing of mitochondrial homeostasis through an NAD+-SIRT1 pathway preserves intestinal barrier function in severe malnutrition. [PDF]

open access: yes, 2023
BACKGROUND: The intestine of children with severe malnutrition (SM) shows structural and functional changes that are linked to increased infection and mortality. SM dysregulates the tryptophan-kynurenine pathway, which may impact processes such as SIRT1-
