Objective: The aim of this study was to compare the diagnostic accuracy of Ga-PSMA-11 PET/CT and multiparametric MRI (mpMRI) in detecting unilateral and bilateral intra-glandular prostate cancer lesions.
Methods: A retrospective analysis was conducted on 73 prostate cancer patients diagnosed via biopsy, all of whom underwent both Ga-PSMA-11 PET/CT and mpMRI prior to surgery. Two independent readers, blinded to each other's results and to pathology findings, evaluated the imaging modalities to make a diagnosis of unilateral (left or right) or bilateral lesions for suspected prostate lesions.

Purpose: Coronectomy is an alternative approach to the complete removal of an impacted mandibular third molar. The present study conducted a systematic review and meta-analysis to compare coronectomy with extraction concerning complications associated with the inferior alveolar nerve injury (IANI).
Methods: This review followed the principles of systematic reviews and meta-analyses.
Prostate-specific membrane antigen (PSMA) is a potential target for the diagnosis and treatment of angiogenesis in clear cell renal cell carcinoma (ccRCC). We aimed to investigate the degree of PSMA signal variability in ccRCC and assess its correlation with neovascularization in the tumor microenvironment. We included 120 patients with suspected renal tumors who underwent [Ga]Ga-PSMA-11 positron emission tomography/computed tomography (PET/CT) scan before surgery in this retrospective study, including 98 ccRCC, 17 non-ccRCC, and 5 benign diseases.

The assessment of consciousness levels and the prediction of wakefulness probabilities are facilitated by F-fluorodeoxyglucose (F-FDG) positron emission tomography (PET). This study aimed to develop a prognostic model for predicting 1-year postinjury outcomes in prolonged disorders of consciousness (DoC) using F-FDG PET alongside clinical behavioral scores.

ZnT8 gene polymorphisms have revealed a relationship between ZnT8 activity and type 2 diabetes (T2D) risk, however, the role of beta-cell ZnT8 is not well understood. A beta cell specific ZnT8 knockout (ZnT8 BKO) mouse model was investigated.

PSMA PET/CT can detect lesions that are not visible on MRI, and the addition of PSMA PET/CT to MRI may improve diagnostic performance. The aim of this study was to incorporate the PRIMARY score or SUVmax derived from [Ga]Ga-PSMA-11 PET/CT into the RC and compare these models with MRI-based RC to assess whether this can further reduce unnecessary biopsies.

After the personalized antigen peptide tumor vaccine, a new nodular lesion, in the upper abdomen, was discovered during 68 Ga-FAPI-04 PET/MRI follow-up. To determine possible pseudoprogression, 68 Ga-FAPI-04 PET/MRI was repeated 39 days later, referring to immune PET response criteria in solid tumors.

Methods: RNA-Seq data, biochemical, and histochemical assays in human and murine OA cartilage as well as primary chondrocytes were utilized to determine lipid dysregulation.
In recent years, researchers have become focused on the relationship between lipids and bone metabolism balance. Moreover, many diseases related to lipid metabolism disorders, such as nonalcoholic fatty liver disease, atherosclerosis, obesity, and menopause, are associated with osteoporotic phenotypes. It has been clinically observed in humans that these lipid metabolism disorders promote changes in osteoporosis-related indicators bone mineral density and bone mass.
