DAU-Net: a novel U-Net with dual attention for retinal vessel segmentation.

In fundus images, precisely segmenting retinal blood vessels is important for diagnosing eye-related conditions, such as diabetic retinopathy and hypertensive retinopathy or other eye-related disorders. In this work, we propose an enhanced U-shaped network with dual-attention, named DAU-Net, divided into encoder and decoder parts. Wherein, we replace the traditional convolutional layers with ConvNeXt Block and SnakeConv Block to strengthen its recognition ability for different forms of blood vessels while lightweight the model.

Topographical and Refractive Outcomes After Corneal Cross-linking in Novice Scleral Lens Users.

Objective: To determine if scleral fittings that occur before corneal cross-linking (CXL) are still successful after the procedure.

Methods: This prospective study included seven patients with keratoconus or post-laser-assisted in situ keratomileusis (LASIK) corneal ectasia who were fitted with scleral lenses then underwent CXL. Four patients (six eyes) had keratoconus and three patients (five eyes) had post-LASIK ectasia.

Visual activity enhances neuronal excitability in thalamic relay neurons.

Amblyopia, a highly prevalent loss of visual acuity, is classically thought to result from cortical plasticity. The dorsal lateral geniculate nucleus (dLGN) has long been held to act as a passive relay for visual information, but recent findings suggest a largely underestimated functional plasticity in the dLGN. However, the cellular mechanisms supporting this plasticity have not yet been explored.

WWC proteins-mediated compensatory mechanism restricts schwannomatosis driven by loss of function.

NF2-related schwannomatosis, previously known as neurofibromatosis type 2, is a genetic disorder characterized by nerve tumors due to gene mutations. Mice with deletion develop schwannomas slowly with low penetrance, hence inconvenient for preclinical studies. Here, we show that NF2, by recruiting E3 ubiquitin ligases β-TrCP1/2, promotes WWC1-3 ubiquitination and degradation.

Methods: A retrospective study was conducted on 29 eyes from 21 patients diagnosed with EE.

Results: The mean age of presentation was 56.

Pupil responds spontaneously to visuospatial regularity.

Beyond the light reflex, the pupil responds to various high-level cognitive processes. Multiple statistical regularities of stimuli have been found to modulate the pupillary response. However, most studies have used auditory or visual temporal sequences as stimuli, and it is unknown whether the pupil size is modulated by statistical regularity in the spatial arrangement of stimuli.

DNA-Dependent Protein Kinase Catalytic Subunit Prevents Ferroptosis in Retinal Pigment Epithelial Cells.

Purpose: The purpose of this study was to investigate the activated core kinases involved in the DNA damage responses (DDR) during ferroptosis of retinal pigment epithelial (RPE) cells in vitro and their regulatory effects on ferroptosis.

Methods: Ferroptosis was induced by erastin in induced RPE (iRPE) cells derived from human umbilical cord mesenchymal stem cells (hUCMSCs), hUCMSCs, and induced pluripotent stem cell-derived RPE (iPSC-RPE) cells. CCK8 was employed to measure the cell viability.

Schlemm's Bidirectional Fluid Wave and Luminal Blood Reflux as Novel Intra-Operative Signs Confirming Optimal Placement of the iStent.

Purpose: Trabecular micro-bypass devices (TBDs) such as the iStent series (Glaukos Corporation, Laguna Hills, CA), are effective in reducing intraocular pressure (IOP). However, precise placement of TBDs is crucial in achieving surgical efficacy, as device malpositioning may lead to suboptimal IOP reduction. We demonstrate two novel intra-operative signs to aid confirmation of accurate iStent placement, without reliance on imaging technologies.

Preliminary efficacy of eye movement desensitization and reprocessing for children aged 1.5-8 years with PTSD: a multiple baseline experimental design ( = 19).

Trauma exposure is common in (pre) school-aged children and around one-fifth of exposed children meet the criteria for post-traumatic stress disorder (PTSD). These symptoms can cause severe impairment to a child's functioning and, if left untreated, have negative long-term consequences. Therefore, there is an urgent need for effective treatment to reduce the acute and long-term effects of trauma.
