The goal of the work described here was to assess the performance of Doppler ultrasound (US) of the superior mesenteric artery (SMA) and celiac trunk (CT) in the evaluation of tumor response in female mice with ovarian peritoneal carcinomatosis treated either with bevacizumab or with carboplatin. Compared with untreated mice, carboplatin-treated mice had a lower weight (23.3 ± 2.0 vs. 27.9 ± 2.9 g, p less then 0.001), peritoneal carcinomatosis index (PCI, 11 ± 3 vs. 28 ± 6, p less then 0.001), Ki67-positive staining surfaces (p less then 0.001), vascular density (p less then 0.001), mean blood flow velocity (mBFVel) in the SMA (7.0 ± 1.4 vs. 10.9 ± 1.8 cm/s, p less then 0.001) and CT (8.0 ± 1.8 vs. 14.3 ± 4.6 cm/s, p less then 0.001) and no ascites. Weight and mBFVel were similar in bevacizumab-treated and untreated mice. The mBFVels in the SMA and CT correlated with the PCI used as an estimation of the tumor burden, R = 0.70 (p less then 0.0001) and R = 0.65 (p less then 0.0001), respectively. Doppler US allows non-invasive assessment of the effects of anticancer therapy in ovarian peritoneal carcinomatosis-induced mice.

A synthetic bone morphogenetic protein (BMP)-2-derived peptide has been discovered to promote bone regeneration. The present study investigated the potential of the BMP-2 peptide combined with hydroxyapatite (HAp)/β-tricalcium phosphate (TCP)/collagen (Col) composite in repairing a peri-implant critical size defect.

Twenty-four saddle-type alveolar defects (10mm mesiodistally and 4mm apicocoronally) were surgically prepared in edentulous ridges in four male beagle dogs. Following implant placement, the defects with vertically exposed implant fixtures received (a) HAp/TCP/Col composite, (b) HAp/TCP/Col+4mg/mL BMP-2 peptide, (c) HAp/TCP/Col+20mg/mL BMP-2 peptide, or (d) HAp/TCP/Col+0.2mg/mL recombinant human BMP-2 (rhBMP-2). Bone regeneration and mineralization were assessed using radiography, micro-computed tomography (micro-CT), fluorescence labeling, and histologic analyses after healing for 4 or 8 weeks. Implant stability was measured using resonance frequency analysis.

The 20mg/mL BMP-2 peptide groups demonstrated a distinguishable advantage in bone regeneration potential over the control groups, as observed on radiographic imaging and histologic examination, although no significant difference was found in implant stability and histomorphometric analysis of mineralization levels. However, the performance of the 20mg/mL BMP-2 peptide groups were inferior to that of the 0.2mg/mL rhBMP-2 groups.

The BMP-2 peptide may accelerate peri-implant bone regeneration. The BMP-2 peptide at 20mg/mL still cannot complete bone repair of peri-implant critical size defect. The BMP-2 peptide at 20mg/mL has similar osteoinductive performance to the rhBMP-2 at 0.02mg/mL.

In this study, the presence and clinical relevance of non-HLA autoantibodies using a recently developed multiplex Luminex-based assay were investigated. Patients with a kidney allograft biopsy at least 6 months after transplantation with a diagnosis of c-aABMR (n = 36) or no rejection (n = 21) were included. Pre-transplantation sera and sera at time of biopsy were tested for the presence of 14 relevant autoantibodies. A significantly higher signal for autoantibodies against Rho GDP-dissociation inhibitor 2 (ARHGDIB) was detected in recipients with c-aABMR as compared to recipients with no rejection. However, ARHGDIB autoantibodies did not associate with graft survival. Levels of autoantibodies against angiotensin II type 1-receptor (AT1R) and peroxisomal trans-2-enoyl-CoA reductase (PECR) were increased in recipients with interstitial fibrosis in their kidney biopsy. Only the signal for AT1R autoantibody showed a linear relationship with the degree of interstitial fibrosis and was associated with graft survival. In conclusion, anti-ARHGDIB autoantibodies are increased when c-aABMR is diagnosed but are not associated with graft survival, while higher levels of AT1R autoantibody are specifically associated with the presence of interstitial fibrosis and graft survival.

To validate the revised 2018 International Federation of Gynecologic and Obstetrics (FIGO) staging system in patients who underwent diagnostic magnetic resonance imaging (MRI) and radiotherapy (RT) for locally advanced cervix cancer.

We analyzed 677 patients who were diagnosed with pelvic MRI and treated with definitive (chemo-)RT for locally advanced cervix cancer (stage IB2/IIA2-IVA or N+) between 1992 and 2018. Patients were classified according to 2009 and 2018 FIGO staging, and survival outcomes were compared. We developed a nomogram to improve prediction of progression-free survival (PFS).

Pelvic and paraaortic lymph nodes were positive in 331 (48.9%) and 78 (11.5%) patients, respectively. Degrasyn At a median follow-up of 77.9 months, the 5-year PFS was 83.5%, 65.2%, 71.0%, 60.6%, 37.6% and 38.9% for IB, IIA, IIB, IIIA, IIIB and IVA according to FIGO 2009 and 88.9%, 60.0%, 73.8%, 66.7%, 36.3%, 68.9%, 43.6%, and 38.9% for IB, IIA, IIB, IIIA, IIIB, IIIC1, IIIC2, and IVA according to FIGO 2018, respectively. Survival of stage IIIC cervix cancer depended on the local extent of the tumor the 5-year PFS of T1, T2, and T3 stages were 80.3%, 73.9%, and 45.5% for IIIC1 and 100%, 44.9%, and 23.4% for IIIC2. Histology, tumor size, node metastasis, FIGO 2009, and treatment modality were independent prognostic factors in the Cox regression analysis, and the nomogram incorporating these factors outperformed FIGO 2009 and FIGO 2018 (AUC 0.718 vs. 0.616 vs. 0.594).

FIGO 2018 revision was associated with heterogenous outcomes among stage III cervix cancer patients. Our nomogram can assist the FIGO system in predicting PFS after definitive RT.
