Prostate cancer is a big threat to male for its poor prognosis and high mortality rate. Natural compounds are important resources of many anticancer drugs. Pomegranate is a kind of antioxidant-rich fruit and its peel and seed has potential anticancer activities. In this study, we aimed to investigate the effects of pomegranate peel extract (PoPx) on the apoptosis and metastasis of prostate cancer cells and the related mechanism. We found that PoPx showed growth inhibition on prostate cancer cells. Nuclei morphological and flow cytometer (FCM) analysis indicated that PoPx could induce prostate cancer apoptosis...

In the post-genomic era, there is an increasing and urgent need for managing and visualizing big data. Data complexity and size will turn information growth into knowledge growth only if presented in a comprehensive and user-friendly way. In such a context, the information technology community collaborates in a multidisciplinary manner with other scientific fields searching for and/or developing tools and services for data management and visualization. We have previously developed DruGeVar, a comprehensive database that triangulates drugs with genes and pharmacogenomic biomarkers to serve clinical pharmacogenomics...

Humans are exposed to pyrrolizidine alkaloids (PA) through different sources, mainly from contaminated foodstuff. Teas and herbal infusions (T&HI) can be contaminated by PA producing weed. PA can possess toxic, mutagenic, genotoxic, and carcinogenic properties. Thus, possible health risks for the general population are under debate. There is a strong safety record for T&HI and additionally epidemiological evidence for the preventive effects of regular tea consumption on cardiovascular events and certain types of cancer...

Nanoparticles for cancer therapy Nanoparticles carry a big promise in oncology, for diagnosis/imaging, therapy, or both (theragnostics). As common in medical history, there is a huge gap between the exciting experimental possibilities and data and clinical studies making use of it. Of the cell-containing nanoparticles, only one formulation using gene-directed enzyme prodrug therapy (GDEPT) with CYP2B1 and ifosfamide was used in early clinical studies. Of the cell-free nanoparticles, some drug-releasing (doxorubicin) ones are in clinical use for trans-arterial chemo-embolization (TACE) in liver tumors and metastasis...

: Reconstruction of full-thickness lower eyelid defects tends to be a devastating procedure, especially when big amount of tissue has to be removed because of oncological reasons. The applied techniques are mostly difficult to execute and multistaged, often require extensive dissection, and result in scarring and facial disfigurement.The aim of the present study is to demonstrate the authors' experience in single-staged reconstructions of full-thickness defects of the lower eyelid with local tissue only. MATERIAL AND METHODS: A retrospective analysis was conducted identifying patients with postexcisional defects after skin cancer occurring in the lower eyelid, reconstructed in 1 stage...

The topic of precision medicine is increasingly more prevalent in the general medical literature with oncology research leading the way. Many factors, such as, availability of targeted drugs, advances in laboratory science, and improved information systems, converged to make precision medicine research possible on a large scale at the National Cancer Institute. The resultant big data will spur new kinds of research in the decades to come, but until then, all clinicians are challenged to make sense of an overabundance of information when managing individual patients...

Ovarian cancer is the most lethal disease among all gynecological malignancies. Interval cytoreductive surgery and cisplatin‑based chemotherapy are the recommended therapeutic strategies. However, acquired resistance to cisplatin remains a big challenge for the overall survival and prognosis in ovarian cancer. Complicated molecular mechanisms are involved in the process. At present, increasing evidence indicates that autophagy plays an important role in the prosurvival and resistance against chemotherapy...

OBJECTIVES: Thyroidectomy is the commonest and most rapidly-growing operation which places normally-functioning laryngeal nerves at risk of injury. Laryngeal palsy is a major risk-factor for dysphonia, dysphagia, and less commonly, airway obstruction. We investigated the association between post-thyroidectomy vocal palsy and long-term risks of pneumonia and laryngeal failure. DESIGN: An N=near-all analysis of the English administrative dataset using a previously-validated informatics algorithm to identify young and otherwise low-risk patients undergoing thyroidectomy for benign disease...

Identifying the prognostic genes in cancer is essential not only for the treatment of cancer patients, but also for drug discovery. However, it's still a big challenge to select the prognostic genes that can distinguish the risk of cancer patients across various data sets because of tumor heterogeneity. In this situation, the selected genes whose expression levels are statistically related to prognostic risks may be passengers. In this paper, based on gene expression data and prognostic data of ovarian cancer patients, we used conditional mutual information to construct gene dependency network in which the nodes (genes) with more out-degrees have more chances to be the modulators of cancer prognosis...

Routine use of regional anesthesia for patients having surgery is supported by general safety and proven effectiveness as a targeted modality in the prevention and treatment of acute pain. Recently, perioperative physicians have become much more interested in improving long-term outcomes after surgery rather than focusing on the well-established short-term benefits of regional anesthesia. This interest has raised important questions regarding the potential influence of regional anesthesia on morbidity and mortality, persistent pain and cancer prognosis...

The National Cancer Institute Genomic Data Commons (GDC) is an information system to store, analyze and share genomic and clinical data from patients with cancer. The recent high-throughput sequencing of cancer genomes and transcriptomes has produced a "big data" problem that precludes many cancer biologists and oncologists from gleaning knowledge from these data regarding the nature of the malignant process and the relationship between tumor genomic profiles and treatment response. The GDC aims to democratize access to cancer genomic data and to foster the sharing of these data to promote precision medicine approaches to the diagnosis and treatment of cancer...

PURPOSE: Lymph node density(LND) has been shown to be a better prognosticator than conventional nodal classification to predict prognosis for squamous cell carcinoma(SCC) of the oral cavity. However, studies focusing on subsites of oral cancer are meager. The role of LND for buccal SCC was evaluated in this study. METHODS: A total of 39 patients with buccal SCC primarily treated surgically with neck dissection were identified. LND was defined as the number of positive nodes over the number of nodal yield...
