Article Synopsis
  • Plant stomatal phenotype traits enhance crop water efficiency, stress resilience, and yield, but current manual measurement methods are slow and labor-intensive.
  • A new real-time recognition network called SLPA-Net was developed for quick and accurate stomata localization and phenotypic analysis using ellipse fitting to extract data like stomatal apertures.
  • The introduction of ECANet improved the accuracy of locating small stomata, and a new Focal EIoU Loss function addressed imbalances in the data, making SLPA-Net effective in detecting and identifying stomata and related traits compared to traditional methods.

Benzo[]pyrene (B[]P) and 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) are widespread environmental pollutants and can destroy thyroid function. We assessed the biochemical changes in the thyroid tissue of rats exposed to B[]P and BDE-47 using attenuated total reflection Fourier-transform infrared spectroscopy combined with support vector machine(SVM). After B[]P and BDE-47 treatment in rats, the structure of thyroid follicles was destroyed and epithelial cells were necrotic, indicating that B[]P and BDE-47 may lead to changes of the thyroid morphology of the rats.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the ongoing coronavirus disease 2019 (COVID-19) pandemic. Host cell invasion is mediated by the interaction of the viral spike protein (S) with human angiotensin-converting enzyme 2 (ACE2) through the receptor-binding domain (RBD). In this work, bio-layer interferometry (BLI) was used to screen a series of fifty-two peroxides, including aminoperoxides and bridged 1,2,4 - trioxolanes (ozonides), with the aim of identifying small molecules that interfere with the RBD-ACE2 interaction.

Gaining insight into the cell-entry mechanisms of swine acute diarrhea syndrome coronavirus (SADS-CoV) is critical for investigating potential cross-species infections. Here, we demonstrated that pretreatment of host cells with tunicamycin decreased SADS-CoV attachment efficiency, indicating that N-linked glycosylation of host cells was involved in SADS-CoV entry. Common N-linked sugars Neu5Gc and Neu5Ac did not interact with the SADS-CoV S1 protein, suggesting that these molecules were not involved in SADS-CoV entry.

The incidence of rheumatoid arthritis (RA) is increasing with age. DNA fragments is known to accumulate in certain autoimmune diseases, but the mechanistic relationship among ageing, DNA fragments and RA pathogenesis remain unexplored. Here we show that the accumulation of DNA fragments, increasing with age and regulated by the exonuclease TREX1, promotes abnormal activation of the immune system in an adjuvant-induced arthritis (AIA) rat model.

The World Health Organization (WHO) criteria for diagnosis of hematopoietic and lymphoid cancers serve as a useful t-ool for distinguishing between malignant conditions based on phenotypic, morphologic, and/or cytogenetic presentations, but their utility is limited in patients whose diseases contain elements of multiple diagnoses. We present a case of a 59-year-old male with enlargement of muscular and soft tissues of the left hip and an intraconal soft tissue mass surrounding the left optic nerve, who was treated for Burkitt-like lymphoma (BLL). Cytogenetics revealed the absence of an MYC rearrangement involving chromosomes 2, 14, or 22, normally found in Burkitt lymphoma, or the classic telomeric losses and proximal gains observed in BLL.
