Deep graph embedding for prioritizing synergistic anticancer drug combinations
In this study, we proposed a Graph Convolutional Network (GCN) model to predict synergistic drug combinations in particular cancer cell lines. Specifically, the GCN method used a convolutional neural network model to do heterogeneous graph embedding, and thus solved a link prediction task. The graph in this study was a multimodal graph, which was constructed by integrating the drug-drug combination, drug-protein interaction, and protein–protein interaction networks. We found that the GCN model was able to correctly predict cell line-specific synergistic drug combinations from a large heterogonous network. The majority (30) of the 39 cell line-specific models show an area under the receiver operational characteristic curve (AUC) larger than 0.80, resulting in a mean AUC of 0.84. Moreover, we conducted an in-depth literature survey to investigate the top predicted drug combinations in specific cancer cell lines and found that many of them have been found to show synergistic antitumor activity against the same or other cancers in vitro or in vivo. Taken together, the results indicate that our study provides a promising way to better predict and optimize synergistic drug pairs in silico.Graphical abstract

Authors: Ahmadianpour MV, Mowla J, Sotoodehnejadnematalahi F, Raheb J Abstract Studies on the blood of patients with prostate cancer using Dynamic Light Scattering (DLS) and corona protein size changes have shown that this test is highly specific and sensitive, but this method has not been studied in Iran, and therefore this study intends to perform this procedure using gold nanoparticles in prostate cancer detection. Blood samples of 60 male subjects aged 40-90 years were collected from 20 healthy, 20 benign and 20 prostate cancer patients. Optical scattering changes were measured by the level of gold nanoparticle...
Conclusion: After the third relapse of HGSC, cytotoxic chemotherapy did not prolong survival but was associated with substantially increased healthcare costs. PMID: 32223298 [PubMed - as supplied by publisher]
CONCLUSION: Our results showed increased percentages of regulatory T cells in pediatric ALL patients despite chemotherapy, which might be compromising the anti-leukemic cellular immune response. PMID: 32224544 [PubMed - in process]
CONCLUSION: These results suggested that rHP-NAP possesses the potential for use as an adjuvant of dendritic cell-based vaccine in anti-melanoma treatment. PMID: 32224538 [PubMed - in process]

We present a case of a 79 year old patient with a medical history of unilateral nerve-sparing radical prostatectomy due to a pT3aN0 (Gleason score 7) prostate carcinoma. Because of slightly elevated prostate specific antigen (PSA) level (0.35ng/dL), a fluorine-18-prostate specific membrane antigen (18F-PSMA)-1007 positron emission tomography/computed tomography (PET/CT) scan was performed, showing no signs of malignant recurrence. However, a moderately PSMA-avid nodular lesion was observed in the left occipital region with homogeneous contrast enhancement, suggestive for a meningioma, which was confirmed on magnetic resona...
