Fuel property effects on knock propensity and thermal efficiency in a direct-injection spark-ignition engine

open access: yes, 2021
Engine knock remains one of the major barriers to further improvement in thermal efficiency of Direct-Injection Spark-Ignition (DISI) engines. While Research Octane Number and Motor Octane Number are often used as standard rating methods for knock ...

Microglia-specific ApoE knock-out does not alter Alzheimer’s Disease plaque pathogenesis or gene expression

open access: yesGlia, 2021
Previous studies suggest that microglial‐expressed Apolipoprotein E (ApoE) is necessary to shift microglia into a neurodegenerative transcriptional state in Alzheimer's disease (AD) mouse models. On the other hand, elimination of microglia shifts amyloid

Biological plasticity rescues target activity in CRISPR knock outs

open access: yesNature Methods, 2019
Gene knock outs (KOs) are efficiently engineered through CRISPR–Cas9-induced frameshift mutations. While the efficiency of DNA editing is readily verified by DNA sequencing, a systematic understanding of the efficiency of protein elimination has been ...

Pnpla3 silencing with antisense oligonucleotides ameliorates nonalcoholic steatohepatitis and fibrosis in Pnpla3 I148M knock-in mice

open access: yesMolecular Metabolism, 2019
Objective Nonalcoholic fatty liver disease (NAFLD) is becoming a leading cause of advanced chronic liver disease. The progression of NAFLD, including nonalcoholic steatohepatitis (NASH), has a strong genetic component, and the most robust contributor is ...

Sexual Dimorphism in Balance and Coordination in p75NTRexonIII Knock-Out Mice

open access: yesFrontiers in Behavioral Neuroscience, 2022
The p75 neurotrophin receptor (p75NTR) is implicated in various biological functions during development and adulthood. Several animal models have been developed to identify the roles of p75NTR in vivo and in vitro. P75NTRExonIII knock-out mice are widely

A huntingtin knock-in pig model recapitulates features of selective neurodegeneration in Huntington’s disease

open access: yesCell, 2018
SUMMARY Huntington’s disease (HD) is characterized by the preferential loss of the medium spiny neurons in the striatum. Using CRISPR-Cas9 and somatic nuclear transfer technology, we established a knock-in (KI) pig model of HD that endogenously expresses

Effect of fuel-air mixture dilution on knock intensity (2nd report: Auto-ignition conditions in end gas preventing intense pressure oscillation)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
This paper studies the condition of reducing knock intensity which is the pressure oscillation initiated by auto-ignition of the end gas. The knock intensity is thought to be decreased by suppressing the reaction rate of auto-ignition. In this study, the

Efficient scar-free knock-ins of several kilobases in plants by engineered CRISPR/Cas endonucleases.

open access: yesMolecular Plant
In plants and mammals, non-homologous end-joining is the dominant pathway to repair DNA double strand breaks, making it challenging to generate knock-in events.
