We report a rare case of restrictive strabismus in a pediatric patient who was initially misdiagnosed with Duane retraction syndrome (DRS) because she had large-angle exotropia, restricted adduction, globe retraction, narrowing of the palpebral fissure, and downshoot on attempted adduction. Notably, the parents first observed strabismus at 12 months of age, with photographs taken before 6 months of age revealing no ocular misalignment. Despite the absence of typical inflammatory signs, the temporal discrepancy, characterized by delayed onset inconsistent with congenital DRS, prompted further investigation.

Background: Studies have utilized optical coherence tomography angiography (OCTA) to assess vessel density in the macular and optic disc regions among patients with keratoconus (KC); however, the findings have been incongruent. This study aimed to systematically investigate the retinal macular and optic disc microvascular characteristics in patients with KC compared to healthy controls using OCTA.

Methods: A comprehensive literature search was performed across multiple electronic databases, including PubMed, Embase, Web of Science, and the Cochrane Library, up to April 2025.

Article Synopsis
  • The study uses advanced spatial transcriptomics to analyze gene expression in human bone marrow, focusing on multiple myeloma and its cellular environment.
  • Researchers examined samples from 21 individuals, revealing distinct plasma cell populations and significant variations in the bone marrow microenvironments of newly diagnosed myeloma patients.
  • Findings suggest that rather than a single universal microenvironment, multiple myeloma subpopulations create varied and unique microenvironments that differ between patients and locations within the bone marrow.

Background: Amblyopia is a common developmental disorder with reduced visual acuity and impairment in binocular functions. Patching the fellow eye, as the gold standard therapy in amblyopia, sometimes fails to achieve satisfactory outcomes because of poor adherence or delayed intervention. Recently, dichoptic/binocular digital therapy in amblyopia has been developed, but no evidence-based binocular treatments with superiority are available.

Determination of α-ketoacids is very important for disease diagnosis as well as for quality control of food and pharmaceuticals. In order to determine α-ketoacids by a simple, rapid, and simultaneous method in complex samples, a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) method has been reported herein through the development of an efficient reactive matrix. In this method, a MALDI matrix, 3,4-diaminobenzophenone (DABP), is first used to generate imidazole derivatives through its rapid reaction with α-ketoacids, which enables simple, rapid, sensitive, and selective detection of α-ketoacids by MALDI-TOF MS.

Objective: To explore the expression and function of microRNA-144 (miR-144) in β-thalassemia (β-thal).

Methods: The expression of miR-144 during the differentiation of murine erythroleukemia (MEL) cells and mouse embryonic liver-derived erythroid precursor cells was analyzed by real-time fluorescence quantitative PCR (qRT-PCR); The expression levels of miR-144 in peripheral blood and day-14.5 embryonic hepatocytes of wild-type (WT) and β-thal mice, as well as the expression levels of miR-144 in peripheral blood of β-thal patients, was also measured by qRT-PCR.

Long-term remote sensing precision depends on real-time radiation calibration, challenging the stability and accuracy of spaceborne calibrators in harsh space environments. Miniature fixed points offer a solution for International System of Units traceability of space radiation values. However, traditional in-situ calibration methods face difficulties due to location mismatches between miniature fixed points and radiation surface.

The current limitations in predicting mechanical properties arise from an incomplete understanding of surface-induced size effects in variable-density polymer lattice metastructures. Through large-scale, high-fidelity finite element simulations, we identify a novel variable-density surface law governing the surface intrinsic length at the macroscopic scale. Capitalizing on this surface law discovery, we propose a surface-enhanced computational homogenization framework.

Microcystin-LR (MC-LR), a toxin produced by cyanobacterial blooms, poses a significant threat to aquatic animals and humans. Biochar (BC), known for its high adsorption capacity, is increasingly being utilized to remove hazardous pollutants from aquatic environment. In the present study, we conducted a full factorial experiment to investigate the potential immunotoxicity in male zebrafish (Danio rerio) exposed to environmentally relevant levels of MC-LR (0, 1, 5, 25 μg/L) and rice straw-derived BC (0, 100 μg/L) for 30 d.

Background: Spatial transcriptomics allows gene expression to be measured within complex tissue contexts. Among the array of spatial capture technologies available is 10x Genomics' Visium platform, a popular method which enables transcriptome-wide profiling of tissue sections. Visium offers a range of sample handling and library construction methods which introduces a need for benchmarking to compare data quality and assess how well the technology can recover expected tissue features and biological signatures.

BuZhong YiQi Formula (BZYQF) can alleviate type 2 diabetes mellitus (T2DM). However, its efficacy in managing postprandial hyperglycemia in T2DM needs to be further confirmed, and its underlying mechanism and pharmacodynamic material basis have not been sufficiently investigated. A T2DM rat model was induced to measure postprandial glycemic responses following glucose and starch ingestion.

Asthma is one of the most common respiratory disorders in Canada, however, many Canadians with asthma remain poorly controlled. In most patients, control can be achieved through appropriate therapy, including: inhaled corticosteroids (ICS), combination ICS/long-acting beta-agonists (LABA), "triple therapy" with ICS/LABA/long-acting muscarinic receptor antagonist (LAMA), and biologic therapies. The medical management of severe asthma, in particular, has changed dramatically with the incorporation of biologics in asthma treatment plans.

The concurrent presence of algal blooms and microplastics pollution in natural water bodies poses a novel threat. However, the joint effects of microcystin-LR (MCLR) in combination with polystyrene microplastics (PSMPs) on the thyroid endocrine system of adult fish remains unclear. In our study, male zebrafish (Danio rerio) were exposed to environmentally relevant concentrations of MCLR alone (0, 0.

Contrast media, including iodinated contrast media and gadolinium-based contrast agents, are commonly administered pharmaceuticals with excellent safety profiles. However, a minority of the population may experience a hypersensitivity reaction following intravenous administration. Hypersensitivity reactions can be immediate or delayed, and range from mild, such as urticaria, to severe, including anaphylaxis.

Sialic acids are the terminal units of glycans in glycoproteins or glycolipids. The determination of sialic acids in glycoconjugates is crucial since they regulate essential biological functions and have a significant nutritional value. To achieve a specific and high-throughput in situ determination of sialic acids in glycoconjugates, a laser-desorption/ionization mass spectrometry (LDI-MS)-based strategy is reported by integrating chemoselective labeling and laser-cleavable mass tagging.

Accumulation of free α-globin is a critical factor in the pathogenesis of β-thalassemia. Autophagy plays a crucial role in clearing toxic free α-globin, thereby reducing disease severity. However, the impact of natural mutations in autophagy-related genes (ATGs) on the phenotypic variability of β-thalassemia remains unclear.
