Three-dimensional spatial localization and volume estimation of prostate tumors using F-PSMA-1007 PET/CT versus multiparametric MRI.

Purpose: Fluorine-18 prostate-specific membrane antigen-1007 positron emission tomography/computed tomography (F-PSMA-1007 PET/CT) has been shown to be superior to multiparametric magnetic resonance imaging (MRI) for the locoregional staging of intermediate-risk and high-risk prostate tumors. This study aims to evaluate whether it is also superior in estimating tumor parameters, such as three-dimensional spatial localization and volume.

Methods: 134 participants underwent F-PSMA-1007 PET/CT and MRI prior to radical prostatectomy as part of the validating paired-cohort Next Generation Trial (NCT05141760).

Large-scale CRISPR/Cas9 deletions within the WFDC gene cluster uncover gene functionality and critical roles in mammalian reproduction.

Despite 96 million years of evolution separating humans and rodents, 11 closely related reproductive tract-specific genes in humans-, , , , , , , , , , and -and the 13 reproductive tract-specific orthologous genes in mice, form highly conserved syntenic gene clusters indicative of conserved, combined critical functions. Further, despite significant progress toward a nonhormonal male contraceptive targeting the protein encoded by one of these genes, epididymal peptidase inhibitor (EPPIN), and associations found between mutations in and an increased risk of male infertility, neither EPPIN nor any closely related whey acidic protein four-disulfide core (WFDC) gene have been explored functionally. To clarify the involvement of WFDC genes in male fertility, we strategically used CRISPR/Cas9 to generate mice lacking 13, 10, 5, or 4 genes within the cluster and demonstrated that males with deletions of 13, 10, or 4 genes (Wfdc6a, Eppin, Wfdc8, and Wfdc6a) were sterile due to an arrest in spermatogenesis, preventing formation beyond round spermatids.

cf. (dinoflagellate): identification and response to nickel and iron stress revealed through chlorophyll .

Metal toxicity in marine ecosystems is a growing issue owing to terrestrial runoff and anthropogenic pollution. cf. , a newly isolated dinoflagellate from New Caledonia, was cultivated in photobioreactors operating continuously with high concentrations of nickel (1.

Is there a minimum percentage of sarcomatoid component required to affect outcomes of localised renal cell carcinoma?

Objective: To evaluate and compare the outcomes of patients with localised renal cell carcinoma (RCC) with and without sarcomatoid features and the impact of this on cancer recurrence and survival.

Material And Methods: The Canadian Kidney Cancer information system database was used to identify patients diagnosed with localised RCC between January 2011 and December 2022. Patients with pT1-T3, n Nx-N0N1, M0 stage and documented sarcomatoid status were included.

Residual Strain Development in Rapid Frontally Curing Polymers.

Frontal polymerization (FP) has emerged as a rapid and energy-efficient process for fabricating thermoset polymers and composites. In this process, a self-propagating reaction front cures the polymer rapidly by the exothermic heat of polymerization reaction instead of an external heat source. Design for FP-based manufacturing in commercial applications requires more comprehensive characterization and prediction of material evolution and residual deformation throughout the process.
