Clinical characteristics and ultrasound biomicroscopic evaluation of anterior segment dysgenesis: a retrospective cross-sectional study.

Background: Anterior segment dysgenesis (ASD) encompasses a range of congenital disorders affecting the development of the eye's anterior segment, often leading to significant visual impairment and glaucoma. Although numerous studies have focused on the genetic basis of ASD, few have comprehensively compared the clinical features across ASD subtypes. This study aims to address this gap by describing and comparing the clinical characteristics and ultrasound biomicroscopy (UBM) imaging features of various ASD subtypes in a Chinese tertiary medical center.

Triangular flaps combined with full-thickness skin graft for repairing concha-type microtia.

Background: Microtia is a common congenital craniofacial malformation, with concha-type microtia presenting unique challenges due to the relatively large residual auricle tissue and flexible surgical methods.

Method: Thirty-five patients with unilateral concha-type microtia were enrolled in this study from January 2023 to June 2024.

Proteome-Wide Analysis of Antibody Responses in Asymptomatic Omicron BA.2-Infected Individuals at the Amino Acid Resolution.

Humoral immunity plays a critical role in clearing SARS-CoV-2 during viral invasion. However, the proteome-wide characteristics of antibody responses in individuals infected with Omicron variant, both asymptomatic and symptomatic, remain poorly understood. We profiled the serum antibodies from 108 individuals, including healthy controls and those infected with Omicron BA.

Comparative Analysis of Two Soybean Cultivars Revealed Tolerance Mechanisms Underlying Soybean Adaptation to Flooding.

Flooding stress poses a significant challenge to soybean cultivation, impacting plant growth, development, and ultimately yield. In this study, we investigated the responses of two distinct soybean cultivars: flooding-tolerant Nanxiadou 38 (ND38) and flooding-sensitive Nanxiadou 45 (ND45). To achieve this, healthy seedlings were cultivated with the water surface consistently maintained at 5 cm above the soil surface.

HLA is a potent immunoinflammatory target in asymptomatic Alzheimer's disease.

Alzheimer's disease (AD) is a common neurodegenerative disease, neuroinflammation is an early pathological feature of AD. However, the alteration of the immune microenvironment in asymptomatic AD was not fully explained. In this study, we aimed to utilize the transcriptome data of AD patients in public databases to reveal the change of immune microenvironment in asymptomatic AD and screen the potential drug targets.

PP2 gene family in Phyllostachys edulis: identification, characterization, and expression profiles.

Background: Phloem protein 2 (PP2), a dimeric lectin, is known for its involvement in plant responses to biotic and abiotic stresses. However, research on PP2 proteins in Moso bamboo is lacking.

Results: In this study, comprehensive genome-wide analysis of the PP2-like gene family was conducted in Moso bamboo (Phyllostachys edulis), which has a significant economic and ecological value.

Butterfly-Inspired Multiple Cross-Linked Dopamine-Metal-Phenol Bioprosthetic Valves with Enhanced Endothelialization and Anticalcification.

Valve replacement is the most effective means of treating heart valve diseases, and transcatheter heart valve replacement (THVR) is the hottest field at present. However, the durability of the commercial bioprosthetic valves has always been the limiting factor restricting the development of interventional valve technology. The chronic inflammatory reaction, calcification, and difficulty in endothelialization after the implantation of a glutaraldehyde cross-linked porcine aortic valve or bovine pericardium often led to valve degeneration.

The Circulating Proteome─Technological Developments, Current Challenges, and Future Trends.

Recent improvements in proteomics technologies have fundamentally altered our capacities to characterize human biology. There is an ever-growing interest in using these novel methods for studying the circulating proteome, as blood offers an accessible window into human health. However, every methodological innovation and analytical progress calls for reassessing our existing approaches and routines to ensure that the new data will add value to the greater biomedical research community and avoid previous errors.

Conjugated Polymer-Based Photo-Crosslinker for Efficient Photo-Patterning of Polymer Semiconductors.

Photo-patterning of polymer semiconductors using photo-crosslinkers has shown potential for organic circuit fabrication via solution processing techniques. However, the performance of patterning, including resolution (R), UV light exposure dose, sensitivity (S), and contrast (γ), remains unsatisfactory. In this study, a novel conjugated polymer based photo-crosslinker (PN3, Figure 1a) is reported for the first time, which entails phenyl-substituted azide groups in its side chains.

Combination of contact ultrasound and infrared radiation for improving the quality and flavor of air-dried beef during hot air drying.

Air-dried beef, a traditional dry fermented meat product in China, whose quality is largely influenced by processing conditions. In this study, contact ultrasound (CU) and infrared radiation (IR) were employed to enhance hot air drying (HAD), with an investigation into the mechanisms underlying improvements in quality and flavor. Samples subjected to CU and IR treatments during HAD (CU-IRD) demonstrated superior color (L* = 42.

Single-stage reconstruction of severe question mark ear with the absence of large portions of the lobule using affected cartilage graft and 3 flaps.

Background: Question mark ear (QME) is a congenital abnormality characterized by a prominent curve within the helix that resembles a question mark. Several surgical reconstruction techniques have been proposed to treat this deformity. In this study, we aimed to evaluate the cosmetic outcomes of a new cartilage and postauricular flap surgical reconstruction technique for patients diagnosed with severe QME.

Auricular growth potential of patients with concha-type microtia after auricular cartilage stretching surgery: A prospective study.

Backgrounds: For patients with concha-type microtia, surgical intervention and the degree of deformity may affect the growth rate of the auricular cartilage, which is different at different ages. This study aimed to explore the auricular growth potential of patients with concha-type microtia at different ages after auricular cartilage stretching surgery.

Methods: A total of 66 patients with unilateral grade II and III concha-type microtia were involved in this prospective cohort study.

Impaired microglial glycolysis promotes inflammatory responses after intracerebral haemorrhage via HK2-dependent mitochondrial dysfunction.

Introduction: Intracerebral haemorrhage (ICH) is a devastating disease that leads to severe neurological deficits. Microglia are the first line of defence in the brain and play a crucial role in neurological recovery after ICH, whose activities are primarily driven by glucose metabolism. However, little is known regarding the status of glucose metabolism in microglia and its interactions with inflammatory responses after ICH.

Effects of contact ultrasound coupled with infrared radiation on drying kinetics, water migration and physical properties of beef during hot air drying.

Drying, as a critical step in the production of air-dried beef, has a direct impact on the quality of the final product.
