PI-RADS v2.1 evaluation of prostate "nodule in nodule" variants: clinical, imaging, and pathological features.

Objectives: To analyze the correlation among the imaging features of prostate "nodule in nodule," clinical prostate indices, and pathology results.

Methods: We retrospectively analyzed the prostate images from 47 male patients who underwent MRI scans and pathological biopsy from January 2022 to July 2023. Two radiologists (R1/R2) evaluated the morphology and signal intensity of the "nodule in nodule" in a double-blind manner and calculated the PI-RADS v2.

Polysaccharide Peptide-Induced Virus Resistance Depends on Ca Influx by Increasing the Salicylic Acid Content and Upregulating the Leucine-Rich Repeat Gene in Arabidopsis thaliana.

Plant viral diseases cause severe economic losses in agricultural production. The development of biosource-derived antiviral agents provides an alternative strategy to efficiently control plant viral diseases. We previously reported that the exogenous application of polysaccharide peptide (PSP) exerts significant inhibitive effects on Tobacco mosaic virus infection in Nicotiana tabacum.

Advances and prospects in biogenic substances against plant virus: A review.

Plant virus diseases, known as 'plant cancer', are the second largest plant diseases after plant fungal diseases, which have caused great damage to agricultural industry. Since now, the most direct and effective method for controlling viruses is chemotherapeutics, except for screening of anti-disease species. As the occurrence and harm of plant diseases intensify, production and consumption of pesticides have increased year by year, and greatly contributed to the fertility of agriculture, but also brought a series of problems, such as the increase of drug resistance of plant pathogens and the excessive pesticide residues.
