Immunosuppression commonly disrupts the homeostasis of mutated normal skin, leading to widespread skin dysplasia and field cancerization. However, the immune system's role in maintaining the normal state of mutated tissues remains uncertain. Herein, we demonstrate that T cell immunity to cutaneotropic papillomaviruses promotes the homeostasis of ultraviolet radiation-damaged skin.

Nevertheless, the pattern of failure (locoregional vs. systemic) after PSMA RGS remains unknown.
View Article and Find Full Text PDFBackground: In a subset of patients with oligorecurrent prostate cancer (PCa), salvage surgery with prostate-specific membrane antigen (PSMA) radioguided surgery (PSMA-RGS) seems to be of value.
Objective: To evaluate whether a lower level of postoperative prostate-specific antigen (PSA; <0.1 ng/ml) is predictive of therapy-free survival (TFS) following salvage PSMA-RGS.
Prostate-specific membrane antigen (PSMA)-based positron emission tomography (PET) imaging allows early detection of metastases in patients with biochemical recurrence. Salvage lymphadenectomy became a widely used method of metastasis-directed treatment. Retrospective analyses show that a low prostate-specific antigen (PSA) value and presence of no more than two affected lymph nodes within the pelvis are factors associated with a good outcome.
View Article and Find Full Text PDFBackground: Targeting prostate-specific membrane antigen (PSMA) has been highly successful for imaging and treatment of prostate cancer. However, heterogeneity in immunohistochemistry indicates limitations in the effect of imaging and radionuclide therapy of multifocal disease. Tc-PSMA-I&S is a γ-emitting probe, which can be used for intraoperative lesion detection and postsurgical autoradiography (ARG).

View Article and Find Full Text PDFLymph node metastases (LNMs) are common in intermediate- to high-risk prostate cancer (PC) and may be missed during extended pelvic lymph node dissection (ePLND). Here we report on the use of prostate-specific membrane antigen (PSMA)-radioguided surgery (RGS) during open radical prostatectomy (RP) with ePLND to resect locoregional LNMs identified on preoperative PSMA positron emission tomography (PET). Preoperative PSMA PET showed 78 LNMs in 35 patients undergoing RP with ePLND and RGS between January 2018 and June 2020.

We hypothesize that the use of archived primary tumor material (PRIM) for PD-L1 testing in clinical trials not properly reflecting the metastatic disease status (MET) contributes to this clinical issue.
Objective: To analyze the predictive and prognostic value of PD-L1, spatial immunephenotypes, and major histocompatibility complex class I (MHC-I) determined in patient-matched PRIM/MET.
Background and Objectives: Although urogenital injuries are common in severely injured patients, their diagnosis is often delayed. Predicting genitourinary injuries (GUI), especially in the immediate stages post injury, remains a challenge. This study aims to evaluate and determine positive predictive factors for the presence of GUI in polytrauma patients.

Patients And Methods: Bladder cancer patients with locally advanced (cT3/4) tumor growth or suspected pelvic lymphogenic spread (cN+) were treated with preoperative cisplatin-containing chemotherapy and consolidative cystectomy with pelvic lymphadenectomy. We aimed to identify prognostic factors and describe the patients' oncological outcome.
Background: Loss of MHC I expression is a tumoral escape mechanism, part of the process of immunoediting. MHC expression patterns and their prognostic and predictive value have not been studied in urothelial carcinoma of the bladder (UC) so far.
Objective: To correlate the expression of MHC I and MHC II with prognosis after curative treatment, response to chemotherapy and checkpoint inhibition.
Background: In a subset of patients with recurrent oligometastatic prostate cancer (PCa) salvage surgery with prostate-specific membrane antigen (PSMA)-targeted radioguidance (PSMA-RGS) might be of value.
Objective: To evaluate the oncological outcomes of salvage PSMA-RGS and determine the predictive preoperative factors of improved outcomes.
Design, Setting, And Participants: A cohort study of oligorecurrent PCa patients with biochemical recurrence (BCR) after radical prostatectomy and imaging with PSMA positron emission tomography (PET), treated with PSMA-RGS in two tertiary care centers (2014-2020), was conducted.
F-rhPSMA-7, and its single diastereoisomer form, F-rhPSMA-7.3, are prostate-specific membrane antigen (PSMA)-targeting radiopharmaceuticals. Here, we investigated their accuracy for the assessment of lymph node (LN) metastases validated by histopathology.

A common approach for editing across multiple sites is to design one guide RNA (gRNA) per target; however, this complicates construct assembly and increases the possibility of off-target mutations. In this study, we utilized one gRNA to target MYB186, a known positive trichome regulator, as well as its paralogs MYB138 and MYB38 at a consensus site for mutagenesis in hybrid poplar (Populus tremula × P.

In particular, irregular cytosine DNA base methylation has been implicated in several diseases, yet the methods for detecting these epigenetic marks are limited to lengthy protocols requiring bulky and costly equipment. We demonstrate a simple workflow for detecting methylated CpG dinucleotides in synthetic and genomic DNA samples using methylation-sensitive restriction enzyme digestion followed by loop-mediated isothermal amplification.
