Background: Disulfiram is widely used to treat alcohol use disorder. Alcohol per se adversely affects bone health. In the experimental study, disulfiram leads to apoptosis of osteoblast and significant osteopenia in adult rats.

Introduction: Paraspinal muscle atrophy has been implicated in low back pain (LBP) as well as degenerative disc disease, lumbar spinal stenosis, and disc herniation. The objective of the study was to determine the association of paraspinal muscle morphology with functional outcomes in patients undergoing spine surgery in degenerative spine diseases.

Research Question: Can the degree of paraspinal muscle atrophy be a reliable prognostic indicator of post-operative functional outcome in patients undergoing surgery for degenerative lumbar spine disease?

Materials And Methods: Forty-one patients with degenerative lumbar spine disease planned for surgery were included.

Article Synopsis
  • This paper explores using Deep Learning and Visual Question Answering systems to improve the detection of wheat rust, a serious disease affecting wheat crops worldwide.
  • It introduces the WheatRustDL2024 dataset, consisting of nearly 8,000 images of healthy and infected wheat leaves, designed to train models for accurate and quick disease diagnosis.
  • The researchers achieved a high accuracy of 97.69% with a fine-tuned ResNet model and utilized techniques like BLIP to enhance the model’s ability to process images and text, resulting in more relevant diagnostic answers.

Purpose: To compare two fast threshold strategies of visual field assessment: SITA-Fast (SF; Humphrey field analyser) and Elisar-Fast (EF; Advanced vision analyser) in patients with glaucoma.

Methods: In this cross-sectional observational study, of total 192 subjects, 138 subjects [150 eyes, 80 glaucoma subjects (91 eyes) and 58 healthy controls (59 eyes)] were analysed and included. Each subject underwent 24-2 EF and SF in randomized order with a minimum time interval of 1 hour between tests.

Diffusion processes govern fundamental phenomena such as phase transformations, doping, and intercalation in van der Waals (vdW) bonded materials. Here, the diffusion dynamics of W atoms by visualizing the motion of individual atoms at three different vdW interfaces: hexagonal boron nitride (BN)/vacuum, BN/BN, and BN/WSe, by recording scanning transmission electron microscopy movies is quantified. Supported by density functional theory (DFT) calculations, it is inferred that in all cases diffusion is governed by intermittent trapping at electron beam-generated defect sites.
