Background: Two risk factors for severe retinopathy of prematurity (ROP) in extremely preterm infants are thrombocytopenia and low levels of arachidonic acid (AA) and docosahexaenoic acid (DHA). To date, these risk factors have not been linked.
Method: Infants born < 28 weeks gestational age (GA) from 2016 to 2019 were randomized to postnatal enteral AA/DHA supplementation or standard care (controls).

Emotional labor, the act of suppressing or altering one's feelings to enhance another person's well-being, is predominantly performed by women, especially within intimate relationships. Despite its impact on well-being, research on its role in sexuality remains limited. We developed the Women's Sexual Emotional Labor Assessment (WOSELA), a 12-item scale based on themes identified by past qualitative studies.

The increasing global prevalence of myopia presents a significant public health concern, and growing evidence has demonstrated that myopia is a major risk factor for the development of open-angle glaucoma. Therefore, timely detection and management of glaucoma in myopic patients are crucial; however, identifying the structural alterations of glaucoma in the optic nerve head (ONH) and retinal tissues of myopic eyes using standard diagnostic tools such as fundus photography, optical coherence tomography (OCT), and OCT angiography (OCTA) presents challenges. Additionally, myopia-related perimetric defects can be confounded with glaucoma-related defects.

Among childhood cancer survivors, the cumulative incidence rate of differentiated thyroid carcinomas (DTCs) is estimated to be 8-11%. Although the association of DTC with prior radiotherapy is well-studied, the association with chemotherapy remains less understood. Most studies focused on young adults, leaving a knowledge gap on subsequent DTC occurring in childhood and adolescence.

Central-place foragers face high predation risk when repeatedly using routes near their nest, as predators can learn to ambush them there. We investigated the factors influencing the likelihood of desert ant foragers falling into pitfall traps, simulating common predators such as antlions or spiders. We varied the spatial configuration of the pitfall traps, the presence of trapped nestmates and the availability of visual landmarks to study the workers' susceptibility to falling into pits and their foraging success.

The ER-resident proteins VMP1 and TMEM41B share a conserved DedA domain, which confers lipid scramblase activity. Loss of either gene results in embryonic lethality in mice and defects in autophagy and lipid droplet metabolism. To investigate their role in pluripotency and lineage specification, we generated Vmp1 and Tmem41b mutations in mouse embryonic stem cells (ESCs).

Purpose: To evaluate whether there are clinical benefits by preparing dental implant sites using piezosurgery instead of conventional rotary drills in healed bone crests and if initial crestal soft tissue thickness could have an impact on marginal bone loss.
Methods: Twenty-five partially edentulous patients requiring two single implants in molar/premolar areas had each site randomly allocated to either piezosurgery or to conventional rotary drill preparation according to a split-mouth design. Definitive screw-retained metal-ceramic crowns were delivered after 6 months.

Functional genomics with libraries of knockout alleles is limited to non-essential genes and convoluted by the potential accumulation of suppressor mutations in knockout backgrounds, which can lead to erroneous functional annotations. To address these limitations, we constructed genome-wide libraries of conditional alleles based on the auxin-inducible degron (AID) system for inducible degradation of AID-tagged proteins in the budding yeast Saccharomyces cerevisiae. First, we determined that N-terminal tagging is at least twice as likely to inadvertently impair protein function across the proteome.

Background: Although to date the pathogenesis of endometriosis remains largely unexplained, it is known that processes of migration, proliferation and revascularization and thus calcium as a messenger substance play an important role. Consecutively, the present study examines the immunohistochemical expression of the calcium transient receptor potential channels 3 and 6 (TRPC3 and TRPC6) in ectopically located (outside the uterine cavity) endometrial tissue.
Methods: Laparoscopically collected and histomorphologically verified endometriosis tissues from several different intraabdominal locations were examined (n = 20) and immunohistochemical stainings were performed with anti-TRPC3 and anti-TRPC6 antibodies (Alomone Labs, Jerusalem).

Understanding the mechanism of self-assembly driven by non-covalent interactions is crucial for designing supramolecular materials with desired properties. Here we investigate the self-assembly of aromatic peptide amphiphiles, Fmoc-LQG and Fmoc-LQG using a combination of spectroscopic, transmission electron and superresolution optical microscopy techniques. Our results show that Fmoc-LQG leads to concentration-dependent assembly, forming fibrous assemblies at low concentrations and supramolecular droplets via liquid-liquid phase separation (LLPS) at higher concentrations.

Background: The liver-heart axis potentially influences the risk of mortality in patients with heart failure. We aimed to identify the clinical utility of the fibrosis-4 (FIB-4) index in patients with heart failure for predicting mortality in the context of metabolic dysfunction-associated steatotic liver disease (MASLD).
Methods: Patients with heart failure and a subsample of healthy participants were enrolled in the MyoVasc study (NCT04064450) and followed for nine years.

: This study aims to compare the effectiveness of traditional rigid probe trabeculotomy and 360-degree catheter trabeculotomy in treating childhood glaucoma, underlining the necessity of early surgical intervention. This retrospective cohort study, conducted at the University Eye Hospital Mainz, Germany, included 109 patients under 18 years with childhood glaucoma who underwent rigid probe trabeculotomy or 360-degree catheter trabeculotomy between January 2015 and February 2021. A total of 151 eyes from 109 patients were included.

The involvement of the aortic arch in thoracic aortic aneurysms (TAA), or acute aortic dissections (AAD), represents a challenging clinical entity, mandating a meticulous surgical plan, tailored to each individual case. The advent of endovascular techniques and the introduction of modern arch protheses have led to the implementation of the frozen elephant trunk (FET) technique. This one-step hybrid operation consists of a total aortic arch replacement combined with an antegrade delivery of a stent-graft for the descending aorta, which acts as a proximal landing zone facilitating a potential distal endovascular reintervention.

Age-related macular degeneration (AMD) is a multifactorial disorder, and there is growing evidence of immunological involvement in its pathogenesis. To address this, we aimed to identify biomarker candidates related to retinal antigens in patients with neovascular AMD treated with ranibizumab and healthy subjects. This study was designed as a prospective, open, parallel-group, interventional, single-center phase IV trial.

: To evaluate correlations between cardiac magnetic resonance imaging (cMRI) at rest including strain imaging and variables derived from quantitative cardiopulmonary exercise testing using a treadmill in patients with pectus excavatum. : We retrospectively correlated the results of cMRI and cardiopulmonary exercise testing in 17 patients with pectus excavatum, in whom both examinations were performed during their pre-operative clinical evaluation. In addition to cardiac volumetry, we assessed the strain rates of both ventricles using a feature-tracking algorithm of a piece of commercially available post-processing software.

Background/objectives: Anal incontinence is linked to pelvic floor dysfunction. Diagnosis involves assessing both the function and structure of the anorectal unit. Although transperineal ultrasound has gained attention as a less invasive option, its effectiveness as a diagnostic tool for evaluating the relationship between structure and function is still debated.

Magnetic skyrmions, topologically stabilized chiral spin textures in magnetic thin films, have garnered considerable interest due to their efficient manipulation and resulting potential as efficient nanoscale information carriers. One intriguing approach to address the challenge of tuning skyrmion properties involves using chiral molecules. Chiral molecules can locally manipulate magnetic properties by inducing magnetization through spin exchange interactions and by creating spin currents.
