Several types of measurements were made to determine the acoustic characteristics that distinguish between voiced and voiceless fricatives in various phonetic environments. The selection was based on a theoretical analysis indicated aerodynamic attributes at boundaries vowels. As expected, glottal vibration extended over longer time obstruent interval for than fricatives, there more extensive transitions first formant adjacent cognates. When two with different voicing adjacent, substantial...
This study reassessed the role of nasal murmur and formant transitions as perceptual cues for place articulation in consonants across a number vowel environments. Five types computer-edited stimuli were generated from natural utterances consisting [m n] followed by [i e o u]: (1) full murmurs; (2) plus segments; (3) last six pulses murmur; (4) starting beginning transitions; (5) surrounding release (three before three after). Results showed that provided much information perception did...
Germline pathogenic mutations in BReast CAncer (BRCA1) genes are thought to drive normal fallopian tube epithelial (FTE) cell transformation high-grade serous ovarian cancer. No human models capture the sequence of events for disease initiation and progression. Here, we generate induced pluripotent stem cells (iPSCs) from healthy individuals young cancer patients with germline BRCA1 (BRCA1mut). Following differentiation into FTE organoids, BRCA1mut lines exhibit cellular abnormalities...
The goal of this study was to determine whether acoustic properties could be derived for English labial and alveolar nasal consonants that remain stable across vowel contexts, speakers, syllable positions. In experiment I, critical band analyses were conducted five tokens each [m] [n] followed by the vowels [i e a o u] spoken three speakers. Comparison nature changes in spectral patterns from murmur release showed that, labials, there greater change energy region Bark 5–7 relative 11–14,...
Foreign accent syndrome (FAS) is a rare speech disorder characterized by change in prosody and other variables yielding altered phonetic characteristics that are perceived as foreign accent. Lesions associated with FAS typically involve left frontoparietal regions. However, 2 reported left-hemispheric stroke patients presenting also had hypoperfusion of the right cerebellum on 99mTc ECD SPECT imaging, presumably from diaschisis. In both cases, there was close parallel between normalization...
Industrial livestock operations (ILOs), particularly processing facilities, emerged as centers of coronavirus disease 2019 (COVID-19) outbreaks in spring 2020. Confirmed cases COVID-19 underestimate true prevalence. To investigate the prevalence antibodies against SARS-CoV-2, we enrolled 279 participants North Carolina from February 2021 to July 2022: 90 households with at least one ILO worker (ILO), 97 high-ILO intensity areas (ILO neighbors [ILON]), and 92 metropolitan (metro). More metro...
This study investigated the acoustic characteristics of voicing in production fricative consonants. The fricatives [f v s z] were used combination with vowels [i e a o u] to create CV syllables, which produced by four subjects both context condition (following voiced and voiceless velar stops) isolation. Analyses conducted time course glottal excitation during noise interval stimuli. Results showed that patterns influenced preceding stop Nonetheless, these carryover coarticulatory effects...
Extended-spectrum β-lactamase (ESBL)-producing and other antimicrobial resistant (AR) Escherichia coli threaten human animal health worldwide. This study examined risk factors for domestic colonization with ceftriaxone-resistant (CR) ESBL-producing E . in semirural parishes east of Quito, Ecuador, where small-scale food production is common. Survey data regarding household characteristics, care, use were collected from 304 households over three sampling cycles, 1195 environmental fecal...
Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL), a family of bacteria that includes Escherichia coli, have emerged as global health threat. This study examined risks associated with carriage third-generation cephalosporin-resistant (3GC-R) E. including ESBL-producing, multidrug-resistant, and extensively drug-resistant (XDR) strains in children living semirural parishes Quito, Ecuador. We conducted longitudinal two cycles sampling (N = 374, N 366) included an analysis...
Abstract Background The rapid spread of extended-spectrum beta-lactamase-producing E. coli (ESBL-EC) is an urgent global health threat. We examined child caretaker knowledge, attitudes, and practices (KAP) towards proper antimicrobial agent use whether certain KAP were associated with ESBL-EC colonization their children. Methods Child caretakers living in semi-rural neighborhoods peri-urban Quito, Ecuador visited surveyed about antibiotics. Fecal samples from one (less than 5 years age) per...
ABSTRACT Industrial livestock operations (ILOs), particularly processing facilities, emerged as centers of coronavirus disease 2019 (COVID-19) outbreaks in spring 2020. Confirmed cases COVID-19 underestimate true prevalence. To investigate prevalence antibodies against SARS-CoV-2, we enrolled 279 participants North Carolina from February 2021 to July 2022: 90 households with at least one ILO worker (ILO), 97 high-ILO intensity areas (ILO neighbors – ILON), and 92 metropolitan (Metro)....
