Philippe M Fortune et al.

American journal of botany, 95(4), 454-464 (2008-04-01)

The origin of polyploid Bromus species of section Genea was investigated using molecular data. This group of annual species native from the Old-World is composed of three diploids, two tetraploids, one hexaploid, and one octoploid. Molecular cloning, sequencing, and phylogenetic

Disabling VEGF-Response of Purkinje Cells by Downregulation of KDR via miRNA-204-5p.

Julian Gehmeyr et al.

International journal of molecular sciences, 22(4) (2021-03-07)

The vascular endothelial growth factor (VEGF) is well known for its wide-ranging functions, not only in the vascular system, but also in the central (CNS) and peripheral nervous system (PNS). To study the role of VEGF in neuronal protection, growth

Sialylation of group B streptococcal capsular polysaccharide is mediated by cpsK and is required for optimal capsule polymerization and expression.

D O Chaffin et al.

Journal of bacteriology, 187(13), 4615-4626 (2005-06-22)

Several bacterial pathogens have evolved the means to escape immune detection by mimicking host cell surface carbohydrates that are crucial for self/non-self recognition. Sialic acid, a terminal residue on these carbohydrates, inhibits activation of the alternate pathway of complement by

Optimization of production of recombinant gamma-tubulin in bacteria.

Jingkai Zhou et al.

MethodsX, 8, 101517-101517 (2021-11-11)

Production of a protein of interest in bacteria and its purification from bacterial lysates are valuable tools for the purification of larger amounts of recombinant proteins. The low cost of culturing, and the rapid cell growth of bacteria make this

Quaternary ammonium N,N,N-trimethyl chitosan derivative and povidone‑iodine complex as a potent antiseptic with enhanced wound healing property.

Celine Abueva et al.

International journal of biological macromolecules, 182, 1713-1723 (2021-05-30)

The importance of developing more potent antimicrobials and robust infection prevention practices has been highlighted recently with the increase in reports of emerging bacterial resistance mechanisms and the development of antibiotic-resistant microbes. In this study, a quaternary ammonium chitosan derivative

Weighing of biomolecules, single cells and single nanoparticles in fluid.

Thomas P Burg et al.

Nature, 446(7139), 1066-1069 (2007-04-27)

Nanomechanical resonators enable the measurement of mass with extraordinary sensitivity. Previously, samples as light as 7 zeptograms (1 zg = 10(-21) g) have been weighed in vacuum, and proton-level resolution seems to be within reach. Resolving small mass changes requires

Grainyhead-Like 3 Influences Migration and Invasion of Urothelial Carcinoma Cells.

Felix Wezel et al.

International journal of molecular sciences, 22(6) (2021-04-04)

Invasive urothelial carcinomas of the bladder (UCB) characteristically show a loss of differentiation markers. The transcription factor Grainyhead-like 3 (GRHL3) plays an important role in the development and differentiation of normal urothelium. The contribution to UCB progression is still elusive.

Acaricidal activities of whole cell suspension, cell-free supernatant, and crude cell extract of Xenorhabdus stokiae against mushroom mite (Luciaphorus sp.).

Prapassorn Bussaman et al.

Journal of Zhejiang University. Science. B, 13(4), 261-266 (2012-04-03)

Xenorhabdus bacterium has been used as a biological control agent against Luciaphorus sp., a mushroom mite endemic in Thailand. To develop an effective formulation of Xenorhabdus stokiae, treatments using different parts of X. stokiae isolate PB09 culture, including whole cell

Use of the Yeast Pichia pastoris as an Expression Host for Secretion of Enterocin L50, a Leaderless Two-Peptide (L50A and L50B) Bacteriocin from Enterococcus faecium L50

Antonio Basanta, Beatriz Gomez-Sala, et al.

Surviving bacterial sibling rivalry: inducible and reversible phenotypic switching in Paenibacillus dendritiformis.

Avraham Be'er et al.

mBio, 2(3), e00069-e00011 (2011-06-02)

Natural habitats vary in available nutrients and room for bacteria to grow, but successful colonization can lead to overcrowding and stress. Here we show that competing sibling colonies of Paenibacillus dendritiformis bacteria survive overcrowding by switching between two distinct vegetative

A modified consumer inkjet for spatiotemporal control of gene expression.

Daniel J Cohen et al.

PloS one, 4(9), e7086-e7086 (2009-09-19)

This paper presents a low-cost inkjet dosing system capable of continuous, two-dimensional spatiotemporal regulation of gene expression via delivery of diffusible regulators to a custom-mounted gel culture of E. coli. A consumer-grade, inkjet printer was adapted for chemical printing; E.

Label-Free Monitoring of Microorganisms and Their Responses to Antibiotics Based on Self-Powered Microbead Sensors.

Jhih-Cheng Wang et al.

ACS sensors, 3(10), 2182-2190 (2018-09-18)

Rapid detection of bacteria and their susceptibility to specific antibiotics plays a vital role in microbial infection treatments. Antimicrobial susceptibility testing (AST) is a common measure to select effective drugs. However, the conventional practices, such as broth dilution, E-test, and

Increased malonyl coenzyme A biosynthesis by tuning the Escherichia coli metabolic network and its application to flavanone production.

Zachary L Fowler et al.

Applied and environmental microbiology, 75(18), 5831-5839 (2009-07-28)

Identification of genetic targets able to bring about changes to the metabolite profiles of microorganisms continues to be a challenging task. We have independently developed a cipher of evolutionary design (CiED) to identify genetic perturbations, such as gene deletions and

Nona-D-arginine therapy for Pseudomonas aeruginosa keratitis.

Priyanka Karicherla et al.

Investigative ophthalmology & visual science, 50(1), 256-262 (2008-09-09)

Nona-D-arginine amide (D9R) was evaluated as treatment for Pseudomonas aeruginosa keratitis when administered alone and with ciprofloxacin. Mouse corneas were infected with P. aeruginosa. Immediately after infection and hourly for 5 hours, eyes received 5 microL of either Dulbecco phosphate-buffered

The CprS sensor kinase of the zoonotic pathogen Campylobacter jejuni influences biofilm formation and is required for optimal chick colonization.

Sarah L Svensson et al.

Molecular microbiology, 71(1), 253-272 (2008-11-20)

Campylobacter jejuni, a prevalent cause of bacterial gastroenteritis, must adapt to different environments to be a successful pathogen. We previously identified a C. jejuni two-component regulatory system (Cj1226/7c) as upregulated during cell infections. Analyses described herein led us to designate
