Mechanistic evaluation of a traditional herbal decoction in attenuating hepatic fibrosis via Nrf2/GPX4 pathway activation and ferroptosis inhibition.

Background: Hepatic fibrosis, a progressive fibrotic response to chronic liver injury, is characterized by excessive collagen deposition and impaired tissue repair. This pathological process leads to liver dysfunction and potential progression to irreversible cirrhosis or hepatocellular carcinoma. Currently, therapeutic options targeting the underlying mechanisms remain limited.

Epigenetic-based combination therapy and liposomal codelivery overcomes osimertinib-resistant NSCLC via repolarizing tumor-associated macrophages.

Osimertinib (Osi) is widely used as a first-line treatment for non-small cell lung cancer (NSCLC) with EGFR mutations. However, the majority of patients treated with Osi eventually relapse within a year. The mechanisms of Osi resistance remain largely unexplored, and efficient strategies to reverse the resistance are urgently needed.

Identification of circRNAs and circRNA-mRNA network of Epinephelus coioides during Singapore grouper iridovirus infection.

Circular RNA (circRNA), one of the important non-coding RNA molecules with a closed-loop structure, plays a key regulatory role in cell processing. In this study, circRNAs of Epinephelus coioides, an important marine cultured fish in China, were isolated and characterized, and the network of circRNAs and mRNA was explored during Singapore grouper iridovirus (SGIV) infection, one of the most important double stranded DNA virus pathogens of marine fish. 10 g of raw data was obtained by high-throughput sequencing, and 2599 circRNAs were classified.

Self-Enhanced Electrochemiluminescence Imaging System Based on the Accelerated Generation of ROS under Ultrasound.

Electrochemiluminescence (ECL) imaging, as an optical technology, has been developed at full tilt in the field of life science and nanomaterials. However, the relatively low ECL intensity or the high co-reactant concentration needed in the electrochemical reaction blocks its practical application. Here, we developed an ECL imaging system based on the rGO-TiO composite material, where the co-reactant, reactive oxygen species (ROS), is generated in situ under the synergetic effect of of ultrasound (US) and electric irradiation.

Pathogenetic and Therapeutic Role of Gut Microbiome in Immunoglobin A Nephropathy.

Immunoglobulin A nephropathy (IgAN) is a common primary glomerulonephritis, which is mainly characterized by excessive IgA deposition in the glomerular mesangial area. Although exploring the pathogenesis of IgAN and improving the treatment strategies continuously, the exact pathogenesis of IgAN remains unclear and the disease still leads to high mortality. Recently, emerging evidence has demonstrated that dysregulated intestinal mucosal immunity and gut microbiome imbalance may play a combined role in the development and progression of IgAN.

Recent progress of metal nanoclusters in electrochemiluminescence.

Metal nanoclusters (MeNCs), composed of a few to hundreds of metal atoms and appropriate surface ligands, have attracted extensive interest in the electrochemiluminescence (ECL) realm owing to their molecule-like optical, electronic, and physicochemical attributes and are strongly anticipated for discrete energy levels, fascinating electrocatalytic activity, and good biocompatibility. Over the past decade, huge efforts have been devoted to the synthesis, properties, and application research of ECL-related MeNCs, and this field is still a subject of heightened concern. Therefore, this perspective aims to provide a comprehensive overview of the recent advances of MeNCs in the ECL domain, mainly covering the emerged ECL available MeNCs, unique chemical and optical properties, and the general ECL mechanisms.

[Evaluation and analysis of auditory function and its clinical characteristics in low birth weight premature infants.].

Objective: To investigate and analyze dynamic changes of auditory function in premature babies with fetal age of less than 37 weeks who were categorized into different birth weight groups and to detect abnormalities of auditory function in these babies and to describe the early development patterns of auditory function in infancy.

Methods: Total of 252 subjects (504 ears) from neonatal ward, neonatal intensive care unit and auditory clinic in Guangzhou Children Hospital, whose fetal age were less than 37 weeks, were included in our study and received auditory function evaluation from January 2004 to February 2008. To investigate the correlation between birth weight and development and abnormality of auditory function in premature babies, all subjects were divided into four groups according to birth weight: View Article and Find Full Text PDF

[Correlation between chirp auditory brainstem response and behavioral hearing threshold in children].

Objective: To investigate the correlation between thresholds in the chirp-ABR and behavior audiogram in order to find out if it is possible to be used as an clinical application of the chirp-ABR in estimating hearing sensitivity.

Methods: Twenty-two cases with hearing loss or normal hearing were enrolled in the study. The behavior audiogram and the response thresholds of chirp ABR (including chirp ABR, L-chirp ABR and U-chirp ABR) were obtained from 35 ears.

[Audiological characteristics and localization of lesions in children with retrocochlear auditory nerve impairment].

Objective: To explore the clinic characteristics, audiological characteristics and location of lesions in children with retrocochlear auditory nerve impairment which, including auditory neuropathy characterized by severely abnormal results of ABR and normal results of DPOAE.

Methods: Between 2002 and 2006, eighty-six cases (165 ears) with severely abnormal ABR but normal results of DPOAE were enrolled in the study group. The mean patient age was one year and one-month-old, with a range of 8 days to 7 years.

[Hearing evaluation of infants failed in hearing screening].

Objective: To analyze the confusing factors and clinical and audiological characteristics in infants failed in hearing screening.

Methods: Between August 2004 and January 2006, 166 infants (315 ears) with detailed birth record and hearing screening record were reviewed in the study. The age of this series ranged from 2 to 6 months.
