We aimed to compare Gleason score and tumor laterality between transrectal ultrasound-guided biopsy of the prostate （TRUsBX） and radical prostatectomy （RP）. some factors that could cause a discrepancy in results between these two procedures were also evaluated. Among the 318 cases reviewed, 191 cases were selected for inclusion in this comparative study, We divided the patients into two groups using the Gleason score： an intermediate/high-grade group （≥7） and a low-grade group （〈6）. Exploratory analyses were conducted for comparisons between groups. We also performed comparisons between TRUsBX and RP for tumor laterality. TRUsBX overestimated 6% and underestimated 24% cases in comparison with RP for Gleason score, and overestimated 2.6% and underestimated 46% cases compared with RP for tumor laterality. Biopsy specimens were slightly smaller in TRUsBX cases with underestimated tumor laterality （P〈 0.05）, and no relationship between the biopsy specimen size and underestimated Gleason score in TRUsBX was found. Prostatic volume showed no statistical correlation with the likelihood of under or overestimation （P 〉 0.05）. Thus, our study showed that TRUsBX has a high likelihood of underestimating both the Gleason score and tumor laterality in prostate cancer （PCa）. The size of the fragment appears to be an important factor influencing the likelihood of laterality underestimation and Gleason score overestimation via TRUsBX. Due to the high likelihood of underestimation of the Gleason score and tumor laterality by 12-core prostate biopsy, we conclude that this type of biopsy should not be used alone to guide therapy in Pca.

Organisms sense and respond to environmental and developmental signals to drive adaptive responses(Kefauver et al.,2020;Yu et al.,2024).These stimuli can be mainly divided into physical and chemical stimuli,and the physical stimuli include light,temperature,sound,vibration,pressure,stretch,shear stress,osmotic stress,and substrate *** of these physical stimuli trigger physical forces and alter membrane tension,which in turn activates mechanosensitive channels(MsCs)and converts the mechanical cues into biochemical signals.

The effect of abiotic stresses on plant C:N:P homeostasis and their mitigation by silicon

引用

The Crop Journal 2024年第2期12卷 340-353页

作者： Milton Garcia costa Renato de Mello Prado Luiz Fabiano Palaretti Jonas Pereira de souza Júnior Department of Agricultural Production science School of Agricultural and Veterinarian SciencesSão Paulo State UniversityJaboticabalBrazil

In crop plants, various environmental stresses affect the balance of carbon, nitrogen, and phosphorus(C:N:P), leading to biochemical and physiological alterations and reductions in yield. silicon(si) is a beneficial element that alleviates plant stress. Most studies involving silicon have focused on physiological responses, such as improvements in photosynthetic processes, water use efficiency, and antioxidant defense systems. But recent research suggests that stressed plants facing either limited or excessive resources(water, light, nutrients, and toxic elements), strategically employ si to maintain C:N:P homeostasis, thereby minimizing biomass losses. Understanding the role of si in mitigating the impact of abiotic stresses on plants by regulating C:N:P homeostasis holds great potential for advancing sustainable agricultural practices in crop production. This review presents recent advances in characterizing the influence of environmental stresses on C:N:P homeostasis, as well as the role of si in preserving C:N:P equilibrium and attenuating biological damage associated with abiotic stress. It underscores the beneficial effects of si in sustaining C:N:P homeostasis and increasing yield via improved nutritional efficiency and stress mitigation.
