RNA-binding proteins (RBPs) contribute to the pathogenesis of proliferative diabetic retinopathy (PDR) by regulating gene expression through alternative splicing events (ASEs). However, the RBPs differentially expressed in PDR and the underlying mechanisms remain unclear. Thus, this study aimed to identify the differentially expressed genes in the neovascular membranes (NVM) and retinas of patients with PDR. The public transcriptome dataset GSE102485 was downloaded from the Gene Expression Omnibus database, and samples of PDR and normal retinas were analyzed...

Alternative splicing (AS) plays a crucial role in regulating gene expression, function, and diversity. However, limited reports exist on the identification and comparison of AS in Eastern and Western pigs. Here, we analyzed 243 transcriptome data from eight tissues, integrating information on transcription factors (TFs), selection signals, splicing factors (SFs), and quantitative trait loci (QTL) to comprehensively study alternative splicing events (ASEs) in pigs. Five ASE types were identified, with Mutually Exclusive Exon (MXE) and Skipped Exon (SE) ASEs being the most prevalent...

BACKGROUND AND AIMS: In response to documented duodenoscope-related infectious outbreaks of multidrug-resistant organisms, the Food and Drug Administration has recommended a transition to duodenoscopes with innovative designs, including duodenoscopes with disposable components or fully disposable duodenoscopes. We aim to characterize the learning curve (LC) for a single-use disposable duodenoscope. METHODS: We performed a retrospective analysis of a prospectively collected database from 31 patients who underwent ERCP by a single, experienced operator using the EXALT Model D® (Boston Scientific, Marlborough) disposable duodenoscope at a single tertiary referral center...

OBJECTIVE: Reactive astrocytes are hallmarks of traumatic spinal cord injury (T-SCI) and are associated with neuropathic pain (NP). Mediating the functional phenotype of reactive astrocytes helps neural repair and ameliorates NP in T-SCI. Here, we aimed to explore the role of tetramethylpyrazine (TMPZ) and astragaloside IV (AGS-IV) in astrocyte polarization and the underlying molecular mechanism in T-SCI. METHODS: Primary cultured astrocytes from mice were treated with LPS or conditioned medium from "M1" polarized microglia (M1-CM), followed by TMPZ and/or AGS-IV administration...

The Elekta Unity MR-linac delivers step-and-shoot intensity modulated radiotherapy plans using a multileaf collimator (MLC) based on the Agility MLC used on conventional Elekta linacs. Currently, details of the physical Unity MLC and the computational model within its treatment planning system (TPS) Monaco are lacking in published literature. Recently, a novel approach to characterize the physical properties of MLCs was introduced using dynamic synchronous and asynchronous sweeping gap (aSG) tests. Our objective was to develop a step-and-shoot version of the dynamic aSG test to characterize the Unity MLC and the computational MLC models in the Monaco and RayStation TPSs...

BACKGROUND: To implement image-guided adaptive radiotherapy (IGART), many studies investigated dose calculations on cone-beam computed tomography (CBCT). A high HU accuracy is crucial for a high dose calculation accuracy and many imaging sites showed satisfactory results. It has been shown that the dose calculation accuracy for lung cancer lags behind. PURPOSE: To examine why the dose calculation accuracy for lung is insufficient, the relative effects of the field-of-view (FOV), breathing motion, and scatter on dose calculation accuracy were studied...

BACKGROUND: Although endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using lumen-apposing metal stents (LAMS) has become one of the treatments of choice for acute cholecystitis (AC) in fragile patients, scant data are available on real-life settings and long-term outcomes. METHODS: We performed a multicenter retrospective study including EUS-guided GBD using LAMS for AC in 19 Italian centers from June 2014 to July 2020. The primary outcomes were technical and clinical success, and the secondary outcomes were the rate of adverse events (AE) and long-term follow-up...

BACKGROUND: In the post-pandemic era, growing apprehension exists regarding the potential sequelae of COVID-19.

INTRODUCTION: Commercial tobacco use was systematically embedded as a valuable commodity through colonisation that continues to be exploited for profit by the Tobacco Industry. There have been significant declines in current smoking prevalence among Aboriginal and Torres Strait Islander peoples 18 years and over, from 55% in 1994 to 43% in 2018-2019. This paper seeks to better understand smoke-free behaviours, and to systematically quantify associations between a range of SDOH and non-smoking/never-smoking among Aboriginal and Torres Strait Islander adults (≥18) living in regional Australia...

Here we evaluated the gill epithelial cell line ASG-10 from Atlantic salmon, as an in vitro model for research on known water quality challenges in aquaculture. Ammonia/ammonium (NH3 /NH4 + ), a recognized challenge in water-intensive recirculating aquaculture systems (RAS), induced lysosomal vacuolization, reduced protein degradation and cell migration of the ASG-10 cells. Aluminium (Aln+ ), another challenge in freshwater aquaculture facilities had only minor effects. Next, we investigated the tolerance for direct water exposure of ASG-10...

Aromatic ammonia lyases (AALs) and tyrosine/phenylalanine ammonia mutases (TAM/PAM) are 3,5-dihydro-5-methylidene-4H-imidazol-4-one- (MIO) dependent enzymes. Usually, the MIO moiety is autocatalytically formed from the tripeptide Ala-Ser-Gly (ASG) and acts as an electrophile during the enzymatic reaction. However, the MIO-forming residues (ASG) have some diversity in this enzyme class. In this work, a systematic investigation on the variety of MIO-forming residues was carried out using in-depth sequence analyses...
