Quantitative Estimation of Iron and Fat Content in Prostate Cancer by Multiparametric MRI and Its Application in Optimizing D'Amico Score.

Background: The risk of biochemical recurrence (BCR) in prostate cancer (PCa) is typically assessed using D'Amico score. However, iron and fat content in PCa are closely related to tumor cell proliferation and the risk of BCR may be estimated using multiparametric MRI (mpMRI).

Purpose: To noninvasively estimate fat and iron content in PCa and to evaluate their utility in enhancing D'Amico scores for predicting BCR in PCa patients.

Application of proton density fat fraction imaging in risk stratification of prostate cancer.

Background: Prostate cancer (PCa) as one of the most prevalent malignancies in men. We introduced a non-invasive quantitative measurement of intraprostatic fat content based on magnetic resonance proton density fat fraction (PDFF) imaging. The study aims to determine the fat fraction (FF) of PCa using proton density magnetic resonance imaging (MRI), gather clinical and routine MRI characteristics, and identify risk factors for high-risk PCa through multifactorial logistic regression.

Complex causal association between genetically predicted 731 immunocyte phenotype and osteonecrosis: a bidirectional two-sample Mendelian randomization analysis.

Purpose: Previous studies have explored the role of immune cells on osteonecrosis. This Mendelian randomization (MR) study further assessed 731 immunocyte phenotypes on osteonecrosis, whether a causal relationship exists, and provides some evidence of causality.

Methods: The 731 immunocyte phenotypes and osteonecrosis data used in this study were obtained from their respective genome-wide association studies (GWAS).

Evaluations of the diagnostic performance of ZOOMit diffusion-weighted imaging and conventional diffusion-weighted imaging for breast lesions.

Background: Diffusion-weighted imaging (DWI) is valuable in the screening, diagnosis, and grading of breast lesions. However, conventional DWI (C-DWI) is prone to chemical shift and distortion. ZOOMit DWI (Z-DWI), as an advanced magnetic resonance imaging (MRI) technique, applies two spatially selective parallel excitation pulses to focus sampling in the hope of obtaining more valuable information.

Value of contrast-enhanced magnetic resonance imaging-T2WI-based radiomic features in distinguishing lung adenocarcinoma from lung squamous cell carcinoma with solid components >8 mm.

Background: Radiomics is one of the research frontiers in the field of imaging and has excellent diagnostic performance. However, there is a lack of magnetic resonance imaging (MRI)-based omics studies on identifying pathological subtypes of lung cancer. Here we explored the value of the contrast-enhanced MRI-T2-weighted imaging (T2WI)-based radiomic analysis in distinguishing adenocarcinoma (Ade) from squamous cell carcinoma (Squ) with solid components >8 mm.

Three-dimensional reconstruction with dual-source computed tomography for evaluating graft deformation and bone tunnel position following reconstruction of the anterior cruciate ligament.

Objective: Considering the limitations of MRI and X-ray and few studies on the use of dual-source computed tomography (DSCT) in anterior cruciate ligament (ACL) reconstruction are limited, this study explored the clinical application of DSCT for three-dimensional reconstruction of graft deformation and bone tunnel position images following ACL reconstruction.

Methods: The data of 123 patients who underwent single-bundle ACL reconstruction under arthroscopy from January 2017 to October 2021 were retrieved. Two weeks after surgery, DSCT was used to assess graft deformation and tunnel widening.

Distinguishing T1-2 and T3a tumors of rectal cancer with texture analysis and functional MRI parameters.

PURPOSE We aimed to investigate whether the texture analysis and functional magnetic resonance imaging (fMRI) could differentiate rectal cancer pathological stages T1-2 (pT1-2) and T3a (pT3a). METHODS Eighty-two rectal adenocarcinoma patients at stage pT1-2 and pT3a received T2 and fMRI examination before surgery. The latter included apparent diffusion coefficient (ADC) sequence, dynamic contrast enhancement (DCE) MRI, and intravoxel incoherent motion (IVIM) diffusion weighted imaging.

, a Novel Allele of , Affects the Mechanical Properties of Rice Plants.

Lodging resistance of rice ( L.) has always been a hot issue in agricultural production. A brittle stem mutant, , was identified by screening an EMS (Ethylmethane sulfonate) mutant library established in our laboratory.

The effects of cognitive load and encoding modality on prospective memory.

Successful execution of an intention as planned is necessary for people's normal life. However, people sometimes even forget intentions that they consider as very important. Hence, the issues that whether prospective memory performance can be improved under high cognitive load tasks are worth discussing.

Native T1-mapping and diffusion-weighted imaging (DWI) can be used to identify lung cancer pathological types and their correlation with Ki-67 expression.

Background: This study aimed to explore the value of native T1-mapping and diffusion-weighted imaging (DWI) in differentiating the pathological types and degree of tumor differentiation of lung cancer and their correlation with Ki-67 protein expression.

Methods: A total of 78 consecutive lung cancer patients who received chest magnetic resonance imaging (MRI) scans between May 2020 and June 2021 were enrolled in this study. Two radiologists independently analyzed the apparent diffusion coefficient (ADC) and T1 values for each lesion.

A correlative study of iron metabolism based on q-Dixon MRI in benign prostatic hyperplasia and prostate cancer.

Clinical staging, Gleason score, and prostate-specific antigen (PSA) have been accepted as factors for evaluating the prognosis of prostate cancer (PCa). With the in-depth study of iron metabolism and the development of multiparametric magnetic resonance imaging technology, we used q-Dixon magnetic resonance imaging (MRI) to measure the iron content of the PCa patients' lesions, and used enzyme-linked immunosorbent assay (ELISA) to measure the iron metabolism indicators in the patients' serum samples, combined with the patients' postoperative clinical data for analysis. We found that the serum indexes were correlated with the T2 star values, International Society of Urological Pathology (ISUP) grade, and pathological classification in PCa patients (all P < 0.

Translating words into actions in working memory: The role of spatial-motoric coding.

Research from a working memory perspective on the encoding and temporary maintenance of sequential instructions has established a consistent advantage for enacted over verbal recall. This is thought to reflect action planning for anticipated movements at the response phase. We describe five experiments investigating this, comparing verbal and enacted recall of a series of action-object pairings under different potentially disruptive concurrent task conditions, all requiring repetitive movements.

Teacher's Emotional Support and Math Performance: The Chain Mediating Effect of Academic Self-Efficacy and Math Behavioral Engagement.

Positive teacher-student interaction can exert a positive influence on student engagement and math performance. As an important part of teacher-student interaction, emotional support of a teacher plays an indispensable role in the math performance of junior middle school and elementary school students. This study aimed to explore the effects of teacher's emotional support on math performance, and examine the mediating role of academic self-efficacy and math behavioral engagement.

Memory for actions in Chinese children with developmental dyslexia.

Around 5-10% of school children in China suffer from reading disabilities. Previous studies have shown that children with developmental dyslexia have deficits in encoding and retrieval information. Moreover, many studies have provided evidence that performing actions can promote the encoding and retrieval of memory compared to verbal tasks.

The output monitoring of performed actions: What can we learn from "recall-recognition" performance?

Memories of simple action phrases are retained better following subject-performed tasks (SPT) than verbal tasks (VT), and this superior memory performance of SPT over VT is referred to as the SPT effect. Although research has been conducted on the SPT effect for more than 30 years, how well participants recognize whether they recalled the items successfully and the relationship between item-specific processing encoding and automatic retrieval have not been addressed. The present study used a 2 (instruction: with or without pleasantness rating) × 2 (type of encoding: SPT or VT) between-subject design and applied a "recall-recognition" paradigm to explore the above issues.

The Role of Item-Specific Information for the Retrieval Awareness of Performed Actions.

Research on action memory has been pursued for more than 30 years, but it is still unclear what drives the recollection process of performed actions. In this study, we used the paradigm and designed two experiments to examine the relation between item-specific processing and retrieval awareness of subject-performed tasks (SPT). The results showed that SPT allows responses in judgments more easily; that is, SPT can enhance the frequency of recalling re-collective experience.

Directed forgetting of negative performed actions is difficult: A behavioural study.

Strong evidence suggests that both performing actions and emotional stimuli can enhance memory by capturing attention. However, the synergetic effect of the two factors on directed forgetting has not been assessed. In this study, we used an item-method directed forgetting paradigm to examine the forgetting of emotional materials depending on whether actions were performed.
