Mitochondria in Retinal Ganglion Cells: Unraveling the Metabolic Nexus and Oxidative Stress.

This review explored the role of mitochondria in retinal ganglion cells (RGCs), which are essential for visual processing. Mitochondrial dysfunction is a key factor in the pathogenesis of various vision-related disorders, including glaucoma, hereditary optic neuropathy, and age-related macular degeneration. This review highlighted the critical role of mitochondria in RGCs, which provide metabolic support, regulate cellular health, and respond to cellular stress while also producing reactive oxygen species (ROS) that can damage cellular components.

A variant associated cone-rod dystrophy with electronegative ERG: A case report and review.

Purpose: Cone-rod dystrophies (CORD) are inherited retinal dystrophies characterized by primary cone degeneration with secondary rod involvement. We report two patients from the same family with a dominant variant in the guanylate cyclase 2D () gene with different phenotypes in the electroretinogram (ERG).

Observations: A 21-year-old lady (Patient 1) was referred due to experiencing blurry vision and color vision impairment.

Cost-Utility Analysis of Bilateral Cochlear Implants for Children With Severe-to-Profound Sensorineural Hearing Loss in Taiwan.

Objectives: Cochlear implants are an option for children with sensorineural hearing loss who do not benefit from hearing aids. Although bilateral cochlear implantation (CI) has been shown to enhance hearing performance and quality of life, its cost-effectiveness remains unclear. This study aimed to evaluate the cost-effectiveness of bilateral CI compared with bimodal hearing for children with sensorineural hearing loss in Taiwan from both the perspectives of patients and Taiwan's National Health Insurance Administration (TNHIA).

Improvement of early miscarriage rates in women with adenomyosis via oxytocin receptor antagonist during frozen embryo transfer-a propensity score-matched study.

Background: Dysfunctional uterine peristalsis seems to play a pivotal role in hindering embryo implantation among women diagnosed with adenomyosis. This research aims to investigate whether administering an oxytocin receptor antagonist during a frozen embryo transfer (FET) cycle using a hormone replacement therapy (HRT) protocol can enhance in vitro fertilization (IVF) outcomes for infertile women affected by adenomyosis.

Methods: Between January 2018 and June 2022, our reproductive center conducted IVF-FET HRT cycles for infertile women diagnosed with adenomyosis.

Intravascular Laser Blood Irradiation (ILIB) Enhances Antioxidant Activity and Energy Metabolism in Aging Ovaries.

Background: Ovarian aging is characterized by the accumulation of free radicals, leading to tissue damage and affecting reproductive health. Intravascular laser irradiation of blood (ILIB, using a low-energy He-Ne laser) is known for its efficacy in treating vascular-related diseases by reducing free radicals and inflammation. However, its impact on ovarian aging remains unexplored.

Validation of the Chinese Version of the Speech, Spatial, and Qualities of Hearing Scale for Parents and Children.

Objectives: To translate and validate the Chinese version of the Speech, Spatial, and Qualities of Hearing Scale (SSQ) for children with hearing impairment (C-SSQ-C) and for their parents (C-SSQ-P).

Design: We translated the SSQ for children into Chinese and verified its readability and comprehensibility. A total of 105 participants with moderate-to-profound hearing loss (HL) and 54 with normal hearing were enrolled in the validation process.

Machine learning-based longitudinal prediction for GJB2-related sensorineural hearing loss.

Background: Recessive GJB2 variants, the most common genetic cause of hearing loss, may contribute to progressive sensorineural hearing loss (SNHL). The aim of this study is to build a realistic predictive model for GJB2-related SNHL using machine learning to enable personalized medical planning for timely intervention.

Method: Patients with SNHL with confirmed biallelic GJB2 variants in a nationwide cohort between 2005 and 2022 were included.

An Antibody-Drug Conjugate for Multiple Myeloma Prepared by Multi-Arm Linkers.

First-line treatment of multiple myeloma, a prevalent blood cancer lacking a cure, using anti-CD38 daratumumab antibody and lenalidomide is often inadequate due to relapse and severe side effects. To enhance drug safety and efficacy, an antibody-drug conjugate, TE-1146, comprising six lenalidomide drug molecules site-specifically conjugated to a reconfigured daratumumab to deliver cytotoxic lenalidomide to tumor cells is developed. TE-1146 is prepared using the HighDAR platform, which employs i) a maleimide-containing "multi-arm linker" to conjugate multiple drug molecules creating a drug bundle, and ii) a designed peptide with a Zn-binding cysteine at the C-termini of a reconfigured daratumumab for site-specific drug bundle conjugation.

The Value of Electroretinography in Identifying Candidate Genes for Inherited Retinal Dystrophies: A Diagnostic Guide.

Inherited retinal dystrophies (IRDs) are a group of heterogeneous diseases caused by genetic mutations that specifically affect the function of the rod, cone, or bipolar cells in the retina. Electroretinography (ERG) is a diagnostic tool that measures the electrical activity of the retina in response to light stimuli, and it can help to determine the function of these cells. A normal ERG response consists of two waves, the a-wave and the b-wave, which reflect the activity of the photoreceptor cells and the bipolar and Muller cells, respectively.

Unraveling the Clinical Relevance of Ferroptosis-Related Genes in Human Ovarian Aging.

Ferroptosis, a recently discovered form of cell death, has been implicated in various diseases. However, the genetic relationship between ferroptosis and ovarian aging has not been thoroughly investigated through informatics analysis. In this study, we conducted bioinformatics analysis using ovarian aging and ferroptosis datasets to identify potential ferroptosis-related genes using R software.

Health Utilities of Bilateral Severe-to-Profound Hearing Loss with Assistive Devices.

Hearing loss is a common sensory disorder in newborns. Early intervention with assistive devices benefits children's auditory and speech performance. This study aimed to measure the health utilities of children with bilateral severe-to-profound hearing impairment with different assistive devices.

Boosting mitochondrial function and metabolism in aging female germ cells with dual ROCK/ROS inhibition.

The decline in oocyte quality with age is an irreversible process that results in low fertility. Reproductive aging causes an increase in oocyte aneuploidy leading to a decrease in embryo quality and an increase in the incidence of miscarriage and congenital defects. Here, we show that the dysfunction associated with aging is not limited to the oocyte, as oocyte granulosa cells also show a range of defects related to mitochondrial activity.

Revisiting Genetic Epidemiology with a Refined Targeted Gene Panel for Hereditary Hearing Impairment in the Taiwanese Population.

Hearing impairment is one of the most common sensory disorders in children, and targeted next-generation sequencing (NGS)-based genetic examinations can assist in its prognostication and management. In 2020, we developed a simplified 30-gene NGS panel from the original 214-gene NGS version based on Taiwanese genetic epidemiology data to increase the accessibility of NGS-based examinations. In this study, we evaluated the diagnostic performance of the 30-gene NGS panel and compared it with that of the original 214-gene NGS panel in patient subgroups with different clinical features.

Additional single dose GnRH agonist during luteal phase support may improve live birth rate in GnRHa-HRT frozen-thawed embryo transfer cycle: a retrospective cohort study.

Background: GnRH agonist (GnRHa) has been reported to have direct effects and functional roles in the endometrium and embryos. Several meta-analyses have shown that GnRHa administration in the luteal phase improved the live birth rate or pregnancy rate in both fresh and frozen embryo transfer (FET) cycles. The aim of this study was to investigate whether luteal GnRHa administration could also improve in vitro fertilization (IVF) outcomes in patients undergoing hormone replacement therapy (HRT) cycles with GnRHa suppression.
