This study aimed to evaluate the effects of coronary collateral circulation (CCC) in patients who had undergone coronary artery bypass grafting (CABG).

A total of 127 patients who had undergone CABG (2011-2013) were enrolled into this study and follow-up was obtained by phone contact. Patients were categorized into two groups according to preoperative CCC using the Rentrop method. Percutaneous coronary intervention (PCI), recurrent myocardial infarction (MI), stroke, heart failure (HF), and mortality rates were compared between groups. Clinical outcome was defined as combined end point including death, PCI, recurrent MI, stroke, and HF.

Sixty-two of 127 patients had poor CCC and 65 had good CCC. There were no differences in terms of PCI, recurrent MI, and HF between the groups. Stroke (seven of 62 [11.3%] and one of 65 [1.5%], P=0.026) and mortality (19 of 62 [30.6%] and 10 of 65 [15.4%], P=0.033) rates were significantly higher in poor CCC group than in good CCC group. In Kaplan-Meier analysis, survival time was not statistically different between the groups. Presence of poor CCC resulted in a significantly higher combined end point incidence (P=0.011).

Stroke, mortality rates, and combined end point incidence were significantly higher in poor CCC patients than in the good CCC group.

Stroke, mortality rates, and combined end point incidence were significantly higher in poor CCC patients than in the good CCC group.

Dedifferentiated liposarcoma (DDLPS) is a rare malignancy that transitions from an atypical lipomatous tumor to a sarcoma with a variable morphologic appearance. The behavior of this tumor in the retroperitoneum is aggressive, but the behavior of DDLPS in the extremities is less well-defined because it is rare. Few reports have assessed the imaging features and clinical outcomes of primary DDLPS in the extremities.

In patients with primary DDLPS of the extremity, we asked the following questions (1) How frequently do additional primary malignancies occur in patients with DDLPS? (2) What is the rate of overall survival, metastases, and local recurrence in DDLPS? (3) What factors are associated with metastasis-free survival and local recurrence in DDLPS?

We defined DDLPS as a biphasic neoplasm that transitions from an atypical lipomatous tumor (ALT) to a sarcoma of variable morphologic appearance and histologic grades. We retrospectively evaluated the medical records of patients with DDLPS of the extremits size may be associated with a greater propensity for local recurrence.

Patients older than 40 years presenting with osteolytic bone lesions are likely to have a diagnosis of carcinoma, even if they had no prior cancer diagnosis. For patients with no prior cancer diagnosis, there is a well-accepted algorithm to determine a potential primary site. That algorithm, however, leaves approximately 15% of people without a detectable primary tumor site, making treatment decisions extremely difficult. Positron emission tomography (PET) fused with CT, more commonly known as PET/CT, has emerged as an important staging modality for many other malignancies but has been used in a very limited fashion in musculoskeletal oncology.

We asked (1) What is the ability of PET/CT to detect the source of the primary tumor in patients with a skeletal metastasis of unknown primary? (2) How does PET/CT perform in detecting metastases in other sites in patients with a skeletal metastasis of unknown primary?

A retrospective analysis between 2006 and 2016 of the pathology database of a single tertiary cf the 35 patients. Among the 35 patients, there were a total of 176 metastatic sites of disease identified, with 115 identified with the standard diagnostic evaluation (before PET/CT).

Among patients with a skeletal metastasis of unknown primary, PET/CT was unable to identify the primary cancer in 12 of 13 patients. PET/CT confirmed the site of the known primary cancer in all 22 patients. There were 176 total metastatic sites. Of the 115 metastases known before PET/CT, PET/CT failed to identify three of 115 (3% false-negative rate).

PET/CT may not provide any additional benefit over the standard evaluation for identification of the primary cancer in patients with a skeletal metastasis of unknown primary, although it may have efficacy as a screening tool equivalent or superior to the standard diagnostic algorithm for evaluation of the overall metastatic burden in these patients.

Level III, diagnostic study.The sICH score quantifies the likelihood of underlying vascular etiology in patients with intracerebral hemorrhage.The NIH Scale/Score is used to quantify stroke severity.The ICH score grades intracerebral hemorrhage severity and subsequent 30-day mortality based on age and CT findings.The HINTS score identifies potential stroke in patients with acute vestibular syndrome.The ASPECTS determines middle cerebral artery stroke severity using available computed tomography data.

Cancer is one of the leading causes of death in the world. Numerous phytochemicals from plants have shown antineoplastic effects via programmed cell death (apoptosis). The aim of this study was to evaluate the effect of anti-proliferative and apoptosis-inducing activity of Acacia modesta and Opuntia monocantha against HeLa cells.

To estimate anti-proliferative activity of the plants against HeLa cells, ethanol solvent was used for the extraction. For the evaluation of anti-proliferative effects, MTT assay was performed with 100, 200, and 400 µg/mL dose. selleck compound The antioxidant assays including glutathione reductase (GSH), superoxide dismutase (SOD) and catalase were performed. Moreover, enzyme linked immunosorbent assay (ELISA) was performed. Furthermore, immunocytometry P53 and flow cytometry were also carried out to assess the apoptosis in HeLa cell.

MTT assay showed that the groups treated with Opuntia monocantha and Acacia modest have less level of toxicity as compared to untreated groups. Antioxidant assays confirmed that GSH, SPD and, catalase activities were quite decreased in treated groups as compared to untreated groups. Similarly, ELISA and apoptosis p53 have shown more pronounced apoptosis effect in treated groups as compared to untreated groups.

Based on above findings, treatment of HeLa cells with these plant extracts induced apoptosis, restricts proliferation, and enhances the anti-oxidative index in post treated cells.<br />.
