From the Department of Ophthalmology, Byers Eye Institute, Stanford University (T.R.R., H.H.G., M.J., J.K., D.M.M.), Palo Alto, California, USA. Electronic address:

Purpose: This study compared two imaging grading techniques to assess the utility of longitudinal image-based analysis in retinopathy of prematurity (ROP) screening: (1) time-limited without image comparison (a proxy for bedside indirect ophthalmoscopy, termed sBIO) and time-unlimited with image comparison (for telemedicine grading, termed TELE) screening. We tested two hypotheses: (1) H1: TELE was superior to sBIO for the detection of change (Tempo)-same, better, or worse and (2) H2: granular data of change (e.g.

Department of Medicine, Center of Excellence in Arrhythmia Research (J.M., W.W., B.S., P.W., N.C., R.C., S.P., K.N., A.K.), Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand.

Article Synopsis
  • Brugada syndrome (BrS) is a hereditary cardiac disorder linked to sudden death in young adults, particularly prevalent in Southeast Asia, with certain genetic variants associated with the condition.
  • Researchers conducted genome sequencing on individuals with BrS and matched controls in Thailand to find rare noncoding variants that are more common in BrS patients.
  • A specific rare variant was identified that disrupts a transcription factor binding site, causing reduced gene expression and reduced sodium current in heart cells, contributing to the high prevalence of BrS in the region and identifying at-risk individuals.

Cotton is the most common natural fibre used in textile manufacture, used alone or with other fibres to create a wide range of fashion clothing and household textiles. Most of these textiles are cleaned using detergents and domestic or commercial washing machines using processes that require many chemicals and large quantities of water and energy. Enzymes can reduce this environmental footprint by enabling effective detergency at reduced temperatures, mostly by directly attacking substrates present in the soils.

  • The study explored the use of magnetic resonance elastography (MRE) as a non-invasive way to detect and measure liver fibrosis in a cancer model using Oncopigs.
  • Seven Oncopigs were subjected to alcoholic liver fibrosis induction and underwent MRE imaging along with liver biopsies over three months to assess liver stiffness and fibrosis grading.
  • Although MRE showed potential for detecting liver stiffness, histological analysis from biopsies was more effective in accurately identifying liver fibrosis, highlighting the need for further research in this area.

Background: Deficits in cognition and motivation predict functioning in depressive and psychotic disorders. However, experimental tasks of cognitive motivation are inconsistently correlated with functioning, time-intensive, and not intuitive in clinical practice. We aimed to develop and validate a self-report instrument to assess motivation processes pertinent to engagement with cognitive activities in daily life.

GlycoRNA consists of RNAs modified with secretory N-glycans that are presented on the cell surface. Although previous work supported a covalent linkage between RNA and glycans, the direct chemical nature of the RNA-glycan connection was not described. Here, we develop a sensitive and scalable protocol to detect and characterize native glycoRNAs.

This paper outlines the therapeutic rationale and neurosurgical targeting technique for bilateral, closed-loop, thalamocortical stimulation in Lennox-Gastaut syndrome, a severe form of childhood-onset epilepsy. Thalamic stimulation can be an effective treatment for Lennox-Gastaut syndrome, but complete seizure control is rarely achieved. Outcomes may be improved by stimulating areas beyond the thalamus, including cortex, but the optimal targets are unknown.

Background And Objectives: Clinical heterogeneity of patients with Parkinson disease (PD) is well recognized. PD with REM sleep behavior disorder (RBD) is a more malignant phenotype with faster motor progression and higher nonmotor symptom burden. However, the neural mechanisms underlying this clinical divergence concerning imbalances in neurotransmitter systems remain elusive.

Lysosome-targeting chimeras (LYTACs) are a promising therapeutic modality to drive the degradation of extracellular proteins. However, early versions of LYTAC contain synthetic glycopeptides that cannot be genetically encoded. Here, we present our designs for a fully genetically encodable LYTAC (GELYTAC), making our tool compatible with integration into therapeutic cells for targeted delivery at diseased sites.

Reductions in remnant cholesterol and VLDL cholesterol through inhibition of ANGPTL3 protein synthesis: an analysis from the TRANSLATE-TIMI 70 trial.

Eur J Prev Cardiol

August 2024

Thrombolysis in Myocardial Infarction (TIMI) Study Group, Brigham and Women's Hospital, Harvard Medical School, 7th Floor, 60 Fenwood Road, Boston, MA 02115, USA.

Aims: Remnant cholesterol and very low-density lipoprotein cholesterol (VLDL-C) are increasingly recognized risk factors for atherosclerotic disease with few therapeutic options. Angiopoietin-like 3 (ANGPTL3), a key protein in the metabolism of triglyceride-rich lipoproteins, is a promising target.

Methods And Results: TRANSLATE-TIMI 70 was a double-blind, placebo-controlled randomized trial testing seven dose regimens of vupanorsen, an antisense oligonucleotide against ANGPTL3, in adults with non-HDL-C ≥ 100 mg/dL and triglycerides 150-500 mg/dL.
