In this study, we investigated the hypothesis that regulatory T cells (T(reg)) are involved in immunomodulatory effects of statins on rheumatoid arthritis (RA) patients. The 12-week study cohort consisted 55 RA patients and 42 control subjects allocated to either a group treated with atorvastatin (AT) (20 mg/day) or non-AT group. T(reg) numbers, suppressive function, serum inflammatory markers, disease activity were evaluated before after therapy. Furthermore, AT frequency function...
Background A wide range of specificity values for the differentiation benign and malignant soft‐tissue tumors show limitations conventional MRI features. The data obtained by quantitative analysis diffusion‐weighted image (DWI) dynamic contrast‐enhanced (DCE) MRIs would provide more objective results, especially in terms cellularity perfusion. Purpose To evaluate diagnostic efficacies DWI DCE tumors. Study Type Retrospective. Subjects In all, 136 patients (68 females, 68 males; age 18–86...
To evaluate the clinical efficacy of ultrafast dynamic contrast-enhanced (DCE)-MRI using a compressed sensing (CS) technique for differentiating benign and malignant soft-tissue tumors (STTs) to factors related grading STTs. A total 165 patients (96 male; mean age, 61 years), comprising 111 with STTs 54 according 2020 WHO classification, underwent DCE-MRI CS between June 2018 2023. The clinical, qualitative, quantitative parameters associated conventional MRI were also obtained. During...
To generate synthetic spine magnetic resonance (MR) images from computed tomography (CT) using generative adversarial networks (GANs), as well to determine the similarities between synthesized and real MR images.GANs were trained transform CT image slices into T2 weighted (MRT2) axial by combining loss voxel-wise loss. Experiments performed 280 pairs of lumbar scans MRT2 images. The then 15 other scans. evaluate whether realistic, two radiologists, surgeons, residents blindly classified Two...

OBJECTIVE. The clumpy artifact has a high misdiagnosis rate, but the not been well studied. aims of this study were to evaluate frequency and location artifacts, rate artifacts as gout, effects raising minimum attenuation value using selective photon shield in dual-energy CT (DECT). MATERIALS AND METHODS. Forty patients without gout who underwent foot ankle DECT enrolled study. Images both sets randomly assigned 130 HU or 150 HU. Three radiologists independently checked all images for...
Background and Objectives: Although reducing the radiation dose level is important during diagnostic computed tomography (CT) applications, effective image quality enhancement strategies are crucial to compensate for degradation that caused by a reduction. We performed this prospective study quantify emphysema on ultra-low-dose CT images were reconstructed using deep learning-based reconstruction (DLIR) algorithms, compared evaluated accuracies of DLIR algorithms versus standard-dose CT....
A malignant melanotic nerve sheath tumor (MMNST), previously known as a schwannoma, is rare variant of peripheral composed Schwann cells with differentiation. Only few reports spinal MMNST have been reported.In the first case, 58-year-old woman presented history low back pain and paresthesia. Magnetic resonance imaging (MRI) computed tomography (CT) lumbar spine revealed an intradural extramedullary mass lesion amorphous linear calcification. Complete resection was performed histological...
To determine the diagnostic availability of dynamic contrast-enhanced (DCE) and diffusion-weighted (DW) MR images for evaluating residual tumours at short-term follow-up after unplanned excision malignant soft-tissue tumours.From January 2013 to September 2014, 38 patients underwent first MRI, including DCE DW imaging (DWI), within 3 months tumour excision. The presence or absence definite nodule formation, focal fluid/haematoma collection, oedema fascial thickening around beds were...
B10 cells are generally considered to inhibit the kidney injury in systemic lupus erythematosus (SLE) mouse models, but recently this function of was denied by lineage-specific deletion IL-10 from B cells. Thus, study aimed determine whether and how play a protective role nephritis (LN). LN non-LN SLE patients without receiving any treatments were recruited, percentages circulating cell determined. Furthermore, purified transferred into MRL/lpr mice, exact effects on progression...
The published antibodies (Abs) against CD22 on B cells including Epratuzumab could inhibit cell activation mainly through binding to C2-set Ig domain of CD22, but they are rarely reported modulate the pathogenic CD4+ T function in systemic lupus erythematosus (SLE). Recently, it was proved that extracellular amino-terminal V-set might mediate interaction and cells, for now exact effect this biology have not been identified. Thus, study, we screened out a peptide termed B2285 from domain,...
The purpose of this study was to evaluate the correlation between dilatation spinal epidural venous plexus (SEVP) and amount fat (EF).Between January 2007 2012, 116 patients with prominent EF control subjects without were included in study. On lumbar MR images, we graded counted number vertebrae determine longitudinal extent EF. We evaluated classified SEVP degree central canal stenosis.SEVP significantly differed group (p-value < 0.0001). Dilatation anterior veins seen all SEVP. In EF, 80...
Most soft tissue tumors show high signal on T2weighted images (T2WIs). Some with the same histologic diagnoses showed different MR appearances in that some had a long T2 while others short (1). Abundant collagen and marked hypocellularity or acellularity soft-tissue tumor hemosiderinladen masses result decreased T2WI (1, 2). Lesions intensity (SI) both T1and T2WIs might represent densely mineralized lesions. And also thrombus, phlebolith, hemorrhage fast blood flow can low T2WI. We defined...
Pathologic fracture is a term used to describe occurring in weakened bone after trivial injury (1, 2). Although there are many causes of weakening, such as, tumors, infections, and some inherited disorders, pathologic fractures usually associated with tumors. The differentiation between malignant benign may be difficult, particularly elderly patients, who commonly suffer from osteoporotic tumors that locally aggressive (3). Moreover, extensive edema hematoma around the site makes it...
