Abstract
OBJECTIVES Increased utilization of computed tomography angiography (CTA) has increased the radiologic diagnosis of penetrating atherosclerotic ulcers (PAUs), which are defined as the ulceration of atherosclerotic plaque through the internal elastic lamina into the aortic media. However, the presentation, treatment indications, and natural history of this disease process remain unclear. METHODS The radiology database at a single university hospital was searched retrospectively for the CTA diagnosis of PAU from January 2003 to June 2009. All scans were interpreted by a cardiovascular radiologist. Information on PAU characteristics and need for surgical repair due to PAU disease was collected. PAU stability or progression was assessed by follow-up CTA, if available. Only PAUs in the aortic arch, descending thoracic aorta, and abdominal aorta were included. RESULTS Three hundred eighty-eight PAUs were diagnosed by CTA interpretation. PAU location was in the aortic arch in 27 (6.8%) cases, the descending thoracic aorta in 243 (61.2%) cases, and the abdominal aorta in 118 (29.7%) cases. Two hundred twenty-four (57.7%) PAUs were isolated (without saccular aneurysm or intramural hematoma); 108 (27.8%) PAUs had associated saccular aneurysms; and 56 (14.4%) PAUs had associated intramural hematoma. Rupture was present in 16 (4.1%) cases. Fifty (12.9%) PAUs underwent repair with thoracic endovascular aortic repair (TEVAR) (n = 30), endovascular aneurysm repair (EVAR) (n = 10), or open surgery (n = 10); primary indications for repair were saccular aneurysm (n = 26), rupture (n = 16), and persistent or recurrent symptoms (n = 8). Even if initially treated conservatively with resolution of pain, symptomatic PAU disease was more likely to require repair than asymptomatic PAU disease (36.2% vs 7.8%, P < .001). Follow-up CTA was available for 87 PAUs, 20 (23.0%) of which demonstrated radiographic disease progression at a mean follow-up of 8.4 ± 10.3 months. Symptomatic PAU disease was more likely to progress than asymptomatic disease (42.9% vs 16.7%, P = .029). CONCLUSIONS For PAUs diagnosed on CTA at a single institution, 4.1% were ruptured and 12.9% underwent repair. Close follow-up imaging appears to be indicated for PAUs, particularly in the case of symptomatic disease, which is more likely to require repair and to undergo radiographic progression.

Abstract
Abstract
Background: Inflammatory breast cancer (IBC) is a highly lethal form of breast cancer which is characterized by skin redness, irritation, swelling, pain, as well as extensive lymph nodes (LN) and hematogenous metastasis. Animal models of IBC are highly desirable for studying its pathology and for designing effective therapies. In this study, we established two new luciferase-and fluorescently-labeled IBC models and tested the efficacy of the novel drug combination nab-paclitaxel and bevacizumab. Methods: Inflammatory SUM149 breast cancer cells were stably transfected with Red Fluorescent Protein (RFP) and Renilla luciferase to establish SUM149-RR, or infected with lentivirus encoding Green Fluorescent Protein (GFP) and Firefly luciferase to establish SUM149- GL. The new cell lines were characterized both in vitro and in vivo. Immunodeficient mice bearing SUM149-RR tumors of 150mm3 in size were treated with saline (control), bevacizumab (4 mg/kg, i.p., twice a week, for 10 weeks), nab-paclitaxel (10 mg/kg, i.v., qdx5), or the combination. Metastasis was analyzed by measuring luciferase activity in the lymph nodes (LN) and lungs.
Results: Luciferase measurements and in vivo imaging showed that both SUM149-RR and-GL clones were highly metastatic to LN, lungs, liver, brain, and spleen. SUM149-RR tumors in control mice displayed ulcerations, edema and redness similar to the clinical disease, while tumors in mice treated with bevacizumab or combination therapy showed no signs of inflammation. Bevacizumab alone decreased tumor growth at later but not early stages of tumor growth, whereas nab-paclitaxel alone inhibited tumor growth by 73%. Combination therapy increased inhibition to 96%, and resulted in 22% (2/9) complete responses. Histologically, tumors from bevacizumab treated groups were more morphologically intact with reduced vascular abnormalities than tumors from control or nab-paclitaxel treated mice. LN and lung metastasis was significantly reduced in all treated groups as compared with control.
Conclusions: The SUM149-RR and SUM149-GL lines are new double-tagged models of human IBC that allow organ visualization and accurate quantification of metastasis. These models can be used to study the biology and treatment of IBC. Combination of nab-paclitaxel with bevacizumab was highly effective against SUM149-RR, suggesting the potential usefulness of this regimen for treatment of IBC patients.

Abstract
Abstract
Background: Triple-negative breast cancers are highly aggressive and resistant to chemotherapy. In this study, we established a new model of triple-negative breast cancer and used it to test the novel combination of nab-paclitaxel with anti-VEGF antibody bevacizumab, which has been effective in treating other metastatic cancer types. Methods: The triple-negative HCC1806 beast cancer cells were stably transfected with dual reporters Red Fluorescent Protein (RFP) and Renilla luciferase to establish the new HCC1806-RR model. Immunodeficient mice bearing orthotopic HCC1806-RR tumors of 150mm3 in size were treated with saline (control), bevacizumab (4 mg/kg. i.p., twice a week, for 10 weeks), nab-paclitaxel (10 mg/kg, i.v., qdx5), or with combination of nab-paclitaxel and bevacizumab. Metastasis was analyzed by measuring luciferase activity in the lymph nodes (LN) and lungs. Results: The HCC1806-RR cells had identical morphology, proliferation rates and sensitivity to nab-paclitaxel as the parental HCC1806 cell line. HCC1806-RR tumors primarily metastasized to LN, with lung being a secondary metastatic site. Combination therapy of nab-paclitaxel and bevacizumab inhibited tumor growth by 100%, as compared to 0% for bevacizumab (P < 0.001) and 90% for nab-paclitaxel (P = 0.024). Importantly, only combination therapy reduced incidence of LN and lung metastases by 50% (P = 0.007) and 87% (P = 0.001). Overall, 50% of the mice in the combination therapy group (n = 10) had complete regressions of both primary tumors and metastases at both regional and distant sites. Conclusions : The HCC1806-RR is a new triple-negative breast model with dual reporters to allow for quantitative assessment of metastatic spread. This model can be used to study the biology and treatment of triple-negative breast cancer. Combination of nab-paclitaxel with bevacizumab was highly effective against HCC 1806-RR tumors, suggesting that this regimen could provide clinical benefits to patients with triple-negative breast cancers.

Abstract
Ebola virus causes irregular outbreaks of severe hemorrhagic fever in equatorial Africa. Case mortality remains high; there is no effective treatment and outbreaks are sporadic and unpredictable. Studies of Ebola virus vaccine platforms in non-human primates have established that the induction of protective immunity is possible and safety and human immunogenicity has been demonstrated in a previous Phase I clinical trial of a 1st generation Ebola DNA vaccine. We now report the safety and immunogenicity of a recombinant adenovirus serotype 5 (rAd5) vaccine encoding the envelope glycoprotein (GP) from the Zaire and Sudan Ebola virus species, in a randomized, placebo-controlled, double-blinded, dose escalation, Phase I human study. Thirty-one healthy adults received vaccine at 2×10(9) (n=12), or 2×10(10) (n=11) viral particles or placebo (n=8) as an intramuscular injection. Antibody responses were assessed by ELISA and neutralizing assays; and T cell responses were assessed by ELISpot and intracellular cytokine staining assays. This recombinant Ebola virus vaccine was safe and subjects developed antigen specific humoral and cellular immune responses.
