Senescence in vitro and ionising radiations—the human diploid fibroblast model [PDF]

, 1981
The influence of ionising radiations on ageing is still controversial. Since Hayflick established the concept that diploid cells have finite lifespan in vitro, human diploid fibroblast (HDF) cultures have been recognised as a potent experimental model ...

Cloning of the pig renal organic anion transporter 1 (pOAT1)

Biochimie, 2002
A pig kidney cDNA library was screened for the porcine ortholog of the multispecific organic anion transporter 1 (pOAT1). Several positive clones were isolated resulting in two alternatively spliced cDNA clones of pOAT1 (pOAT1 and pOAT1A). pOAT1-cDNAs consist of 2126 or 1895 base pairs (EMBL Acc. No.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

Advanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Carbonic anhydrase 5 regulates acid-base homeostasis in zebrafish.

PLoS ONE, 2012
The regulation of the acid-base balance in cells is essential for proper cellular homeostasis. Disturbed acid-base balance directly affects cellular physiology, which often results in various pathological conditions. In every living organism, the protein

Persistence of Dominant T Cell Clones in Accepted Solid Organ Transplants [PDF]

The Journal of Immunology, 2001
Abstract Donor/recipient MHC class II matching is beneficial to the survival of allogeneic kidneys in humans and swine. In the latter, tolerance to class I-disparate grafts can be induced by a short course of immunosuppression, a peripheral mechanism that implicates regulatory T cells.

Quantum Emitters in Hexagonal Boron Nitride: Principles, Engineering and Applications

Advanced Functional Materials, EarlyView.
Quantum emitters in hexagonal boron nitride have emerged as a promising candidate for quantum information science. This review examines the fundamentals of these quantum emitters, including their level structures, defect engineering, and their possible chemical structures.

Triple-barrel Organization of ENaC, a Cloned Epithelial Na+ Channel [PDF]

Journal of Biological Chemistry, 1996
A cloned rat epithelial Na+ channel (rENaC) was studied in planar lipid bilayers. Two forms of the channel were examined: channels produced by the alpha subunit alone and those formed by alpha, beta, and gamma subunits. The protein was derived from two sources: either from in vitro translation reaction followed by Sephadex column purification or from ...

High‐Throughput Microfluidic‐Mediated Assembly of Layer‐By‐Layer Nanoparticles

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.

Mapping the Trypanosoma cruzi Genome: Analyses of Representative Cosmid Libraries

BioTechniques, 1996
In order to generate contiguous cosmid coverage of the genome of the protozoan parasite Trypanosoma cruzi for large-scale sequence analysis, a cosmid library of 36864 individual, primary clones was generated.

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation

Advanced Functional Materials, EarlyView.
This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence
