(Erysiphaceae, Ascomycota) is an obligate plant pathogenic group causing powdery mildew on diverse angiosperm plants, including economically significant crops. Despite advancements in the taxonomy and phylogeny of species using ribosomal DNA markers (ITS and LSU), several taxonomic issues remain unresolved. Previously, the glyceraldehyde-3-phosphate dehydrogenase () gene, which exhibits higher nucleotide variation, has been proposed as an additional marker for powdery mildew species.

For short periods, even without the presence of red blood cells, hyperbaric oxygen can safely allow plasma to meet the oxygen delivery requirements of a human at rest. By this means, hyperbaric oxygen, in special instances, may be used as a bridge to lessen blood transfusion requirements. Hyperbaric oxygen, applied intermittently, can readily avert oxygen toxicity while meeting the body's oxygen requirements.

Environmentally persistent free radicals (EPFRs) are a recently recognized component of particulate matter that cause respiratory and cardiovascular toxicity. The mechanism of EPFR toxicity appears to be related to their ability to generate reactive oxygen species (ROS), causing oxidative damage. EPFRs were shown to affect P450 function, inducing the expression of some forms through the Ah receptor.

Cardiomyocyte myofilament function in common animal models of heart failure with preserved ejection fraction.

J Mol Cell Cardiol

December 2024

Divison of Cardiology, Johns Hopkins University School of Medicine, 1800 Orleans St, Baltimore, MD 21205, United States of America. Electronic address:

Human cardiomyocytes from very obese patients with heart failure and preserved ejection fraction (HFpEF) have markedly depressed calcium-activated tension and increased resting stiffness. To test if either are recapitulated by obese-HFpEF animal models, tension‑calcium and tension-sarcomere length relations were measured in myocytes from mice on a high fat diet (HFD) with L-NAME, ZSF1 rats, and Göttingen minipigs on HFD + DOCA (MP). Only MP myocytes displayed reduced Ca-activated tension, and none exhibited increased resting stiffness versus respective controls.

Center for Computation & Technology and Department of Environmental Sciences, Louisiana State University, Baton Rouge, LA 70803, USA.

Article Synopsis
  • Dysregulation of lung collagen levels is crucial for understanding lung disease progression, but traditional scoring methods are subjective, inconsistent, and time-consuming due to manual histopathology.
  • A machine learning framework was developed for automated scoring of lung collagen content using a dataset from adult female mice, incorporating features from images and statistical data.
  • The approach achieved an average accuracy of 83% in binary classification and 73% in multi-label classification tasks, demonstrating its effectiveness in predicting lung cancer and quantifying collagen structural alterations.

  • Black-bellied Whistling-Ducks (BBWD) are moving north into areas occupied by Eastern Wood Ducks (WODU), but their nesting habits are still not well understood.
  • To研究 their nesting behavior, researchers utilized advanced technology like passive integrated transponder (PIT) tags and RFID readers on nest boxes, allowing them to track visits and behaviors of both BBWD and WODU during key nesting stages.
  • The study found that while both species visited new and old nest boxes equally, BBWD favored old boxes for nesting significantly more than WODU, challenging previous expectations and highlighting gaps in traditional research methods.

Background: Patients undergoing primary total knee arthroplasty (TKA) who have a history of meniscectomy have worse postoperative functional outcomes, increased rates of early postoperative complications, and higher revision rates. Despite knowing this, to the best of our knowledge, it has not been previously studied whether the timing of meniscectomy before TKA impacts functional outcomes after undergoing TKA. Compared to patients who underwent meniscectomy more than one year before TKA, do patients who have meniscectomy less than one year before TKA have significantly different postoperative outcomes?

Methods: A retrospective cohort study was conducted at an academic medical center.
