Self-monitoring for speech errors: Two-stage detection and repair with and without auditory feedback

Publication date: August 2017 Source:Journal of Memory and Language, Volume 95 Author(s): Sieb G. Nooteboom, Hugo Quené Two experiments are reported, eliciting segmental speech errors and self-repairs. Error frequencies, detection frequencies, error-to-cutoff times and cutoff-to-repair times were assessed with and without auditory feedback, for errors against four types of segmental oppositions. Main hypotheses are (a) prearticulatory and postarticulatory detection of errors is reflected in a bimodal distribution of error-to-cutoff times; (b) after postarticulatory error detection repairs need to be planned in a time-consuming way, but not after prearticulatory detection; (c) postarticulatory error detection depends on auditory feedback. Results confirm hypotheses (a) and (b) but not (c). Internal and external detection are temporally separated by some 500ms on average, fast and slow repairs by some 700ms. Error detection does not depend on audition. This seems self-evident for prearticulatory but not for postarticulatory error detection. Theoretical implications of these findings are discussed.

The increasing number of senescent cells present in older tissues is one of the root causes of degenerative aging. It is also the closest to being effectively reversed. An open access paper describing the evidence for HSP90 inibitors to selectively destroy senescent cells was published earlier this month. I had half missed it in passing and half skipped over it in favor of a more general review of the current state of senolytic drug development, pharmaceuticals capable of clearing senescent cells, but on reflection I think it is worth pointing out. The number of senolytic drug candidates has not yet reached a count of twen...

Publication date: 1 November 2017 Source:Neuroscience Letters, Volume 660 Author(s): Sujeong Jang, Hyong-Ho Cho, Jong-Seong Park, Han-Seong Jeong Bone marrow-derived mesenchymal stem cells (BM-MSCs), which are characterized by multipotency and self-renewal, are responsible for tissue regeneration and repair. We have previously reported in adipose tissue-derived MSCs that only Wnt5a is enhanced at neurogenic differentiation, and the mechanism of differentiation is dependent on the Wnt5a/JNK pathway; however, the role of Wnt/MAPK pathway is yet to be investigated in neurogenic differentiation in BM-MSCs. We compared the tra...

AbstractRecently, there has been tremendous development in mitral valve repair, especially in imaging modalities, minimally invasive approaches and surgical techniques. Among various surgical techniques, leaflet techniques have also advanced for treatment of different types of mitral valve diseases. The optimal leaflet technique depends on the involvement of anterior or posterior leaflet, aetiology of the disease and the usage of surgical approach. In degenerative disease for posterior leaflet prolapse, the current trends are from classical quadrangular resection to limited triangular resection. Development of techniques l...

ev VN Abstract The sulfur-containing amino acid methionine (Met) plays critical roles in protein synthesis, methylation, and sulfur metabolism. Both in its free form and in the form of an amino acid residue, it can be oxidized to the R and S diastereomers of methionine sulfoxide (MetO). Organisms evolved methionine sulfoxide reductases (MSRs) to reduce MetO to Met, with the MSRs type A (MSRA) and type B (MSRB) being specific for the S and R forms of MetO, respectively. In mammals, the selenoprotein MSRB1 plays an important protein repair function, and its expression is tightly regulated by dietary selenium. In thi...

AbstractInterpretation of next-generation sequencing (NGS) of tumor tissue in patients with advanced Urinary Tract Cancer (UTC) is performed to guide treatment selection but may reveal pathogenic variants with germline implications. We identified three patients with UTC with unexpected germline DNA repair gene mutations. Specific testing for these was prompted by the detection of these mutations by tumor NGS. All three patients were nonsmokers with a strong family history of cancer. Two patients had upper tract UTC with age at diagnosis in the 40  s. One had a family history suggestive of hereditary breast/ovarian pre...

Abstract Hernia repair is usually accompanied with the implantation of a synthetic mesh, which frequently results in a foreign body response and serious complications. In the present study, a novel biodegradable chitin‐based hernia patch was prepared and characterized. Biomechanical properties and biodegradability of the chitin patch were quantified in vitro and in vivo. In repair of the rat abdominal wall full‐thickness defect model, the chitin patch induced more abundant new blood vessels with milder tissue inflammation and fibrosis compared with polypropylene mesh. Chitin patch effectively inhibited excessive secret...
