Inferring spatial and signaling relationships between cells from single cell transcriptomic data. [PDF]

open access: yes, 2020
Single-cell RNA sequencing (scRNA-seq) provides details for individual cells; however, crucial spatial information is often lost. We present SpaOTsc, a method relying on structured optimal transport to recover spatial properties of scRNA-seq data by ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Germ cells [PDF]

open access: yesCurrent Opinion in Genetics & Development, 1999
Recently, cell signaling has been shown to be required for the formation of germ cells in the mouse embryo, direct observation of germ cell migration in living mouse embryos has been achieved, novel genes that control germ-cell migration have been identified in Drosophila, and the roles of many components of germ plasm in several species have become ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Past, present, and future of microcarrier-based tissue engineering

open access: yesJournal of Orthopaedic Translation, 2015
The top issue in tissue engineering is how to obtain more seed cells quickly and to preserve their characteristic morphology during in vitro expansion culture of cells. Microcarriers can help to amplify cell numbers and maintain the appropriate phenotype

Design and Simulation of Cyclic Battery Tester

open access: yesPower Electronics and Drives, 2020
The paper presents an approach to the modelling of a cyclic battery tester and contains observations about lithium-ion (Li-ion) batteries, charging/discharging procedures, conditions and protections which must be observed during the testing process.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Low Cost, Adhesion Strength Based Cell Sorter [PDF]

open access: yes, 2017
In many in vitro experiments, primary cells are harvested from an animal species to undergo experimental manipulation and subsequent analysis. Cell sorters are a luxury to have after cell harvesting to ensure pure populations of cells.
