Summary: The study aimed to characterize the acoustic profile and evaluate the intelligibility of vowel productions in prelingually deafened, Mandarin-speaking children with cochlear implants. It found that these children exhibited measurable acoustic deviations and lower vowel intelligibility compared to normal hearing children, with longer duration, more scattered vowel categories, smaller vowel space area, and lower recognition accuracy.

Summary: This study evaluated the intelligibility of obstruent consonants in prelingually deafened Mandarin-speaking children with cochlear implants (CIs). Results showed that the CI children had lower intelligibility compared to normal hearing (NH) children, particularly in sibilant sounds. Chronological age and age at implantation were found to significantly impact the development of obstruent consonants in CI children.

Summary: This study used fNIRS to investigate cortical activation patterns to speech in quiet and speech in noise in prelingual cochlear implant users. The findings revealed differences in activation patterns between individuals with normal hearing and cochlear implant users, supporting the role of the middle temporal gyrus as a neural marker for speech understanding in cochlear implant patients.

Summary: This study found that youth with cochlear implants have poorer functional hearing quality compared to peers with normal hearing, and this is associated with speech-language and executive functioning outcomes in CI users. The Quality of Hearing Scale (QHS) is a valid measure of functional hearing quality that is distinct from traditional audiometric measures.

Summary: This study explores the effects of white matter lesions (WMLs) on hearing and speech rehabilitation in prelingually deaf children after cochlear implantation. The results show significant differences in auditory and speech abilities between the WMLs group and the control group post-operation. WMLs should not be considered a contraindication for cochlear implantation, but comprehensive evaluation is needed for patients with severe WMLs.

Summary: The purpose of this study was to compare cochlear implant users and normal-hearing peers in word retrieval during phonological and semantic verbal fluency tasks. The results showed that cochlear implant users generated fewer words compared to normal-hearing peers throughout the entire 60-second task. Cochlear implant users had longer start latency times and produced fewer clusters and switches in the phonological fluency task. Speech perception and verbal working memory were more strongly associated with verbal fluency scores in cochlear implant users.

Summary: The study compared QoL, self-perceived hearing benefit, and audiometric results after CI between prelingually and postlingually deafened patients. It found better auditory performance in the postlingually deafened group, but no significant differences in perceived QoL or CI benefit between the groups. Additionally, sound-deprived, prelingually deafened patients may benefit from CI.

Summary: Currently, there is a lack of evidence-based guidelines for fitting cochlear implants, resulting in variability in fitting practices and outcomes. This study investigates the relationship between fitting parameters and speech perception outcomes, finding a correlation between dynamic range and speech audiometry results.

Summary: The study aimed to evaluate a novel technique of electrode deactivation based on postoperative cone beam computed tomography (CBCT) images in post-lingually deafened adult cochlear implant recipients. Results showed statistically significant improvements in speech recognition tests in both silence and noise environments with the new technique compared to the standard map. All participants selected the new technique as their preferred map after 4 weeks of use.

Summary: This study proposes a method for speech denoising in cochlear implants using a deep neural network, which achieves good results. By taking raw audio as input and providing a denoised electrodogram, the method can automatically remove interfering noises and improve speech understanding.

Summary: This study aimed to assess the effect of pitch contour and timbre on the perception of prelingually deafened young cochlear implant (CI) users. The results showed that mixed timbre condition led to poorer melodic contour identification, while fixed and mixed pitch conditions resulted in poorer speech perception. Auditory short-term memory positively correlated with melodic contour identification, and CI users demonstrated similar trends to normal-hearing peers in certain aspects.

Summary: Studies suggest that the IPG Effect can be used to estimate the density of spiral ganglion neurons and correlates with speech recognition performance. Selecting electrode sites for stimulation based on the IPG Effect can improve CI users' performance on speech recognition tasks.

Summary: Reproductive efficiency is crucial for the profitability of dairy operations, and manipulating reproductive physiology through optimized TAI programs, genetics, and management practices can enhance fertility. Factors such as transition management, body condition score changes, and cow comfort also play a significant role in improving reproductive efficiency. High 21-day pregnancy rates are sought after to reduce calving intervals and days in milk, with adjustments in TAI protocols and presynchronization programs showing potential for increased fertility.

Summary: The study aimed to evaluate the factors related to anovulation in postpartum cows, discovering that longer dry periods, lower BCS, and diseases were associated with anovulation, with different sizes of anovular follicles showing varying risk factors.

Summary: The Ovsynch protocol has been proven to increase pregnancy per artificial insemination (P/AI) in lactating dairy cows, compared to cows inseminated after a detected estrus. Implementing timed artificial insemination (TAI) programs has been an important factor in the significant improvement of reproductive performance in lactating dairy cows in the United States over the past 20 years.

Summary: This study aimed to investigate the impact of low-dose hCG on multiple ovulations in lactating dairy cows. The results showed that increased hCG led to larger follicle sizes and higher FSH concentrations, resulting in an increased frequency of double ovulation.

Summary: This study shows that prostaglandin F2alpha (PGF2A) produced by the endometrium and corpus luteum is critical for luteal regression, and can stimulate its own synthesis. Understanding the endocrine profile of PGF2A autoamplification is crucial for understanding the response of the corpus luteum and endometrium to PGF2A.

Summary: The bovine high fecundity allele, Trio, leads to multiple ovulations and slower development of antral follicles. It also results in smaller ovulatory capacity. This study explores the effect of the Trio allele on early folliculogenesis.

Summary: This manuscript reviews the mechanisms that maintain the corpus luteum (CL) during pregnancy in ruminants. It discusses the role of luteinizing hormone (LH) in ovulation and luteinization, as well as the involvement of oxytocin-induced prostaglandin F2 alpha (PGF2A) pulses and decreased progesterone production in maintaining the CL. The study also highlights the importance of embryonic interferon-tau (IFNT) in suppressing uterine secretion of PGF2A and preventing luteolysis during early pregnancy, as well as the potential mechanisms for luteal maintenance in later stages.

Summary: This review summarizes the results of fixed-timed artificial insemination (TAI) fertility studies conducted in the past 27 years, evaluates the impact of synchronization protocols on reproductive performance, and provides perspective on the future of TAI programs in beef cattle. The study found that TAI technology has been successfully utilized in the beef cattle industry, increasing pregnancy rates and leading to earlier calvings.
