This interesting effect of nanotexture on translocation behavior of tumor cells is important for the early detection of cancer.PAX2 is an essential transcription factor for development. Aberrant PAX2 expression in adult tissues is associated with carcinogenesis and experimental evidence shows that PAX2 generally exhibits oncogenic properties. Although PAX2 is not expressed in normal ovaries, it is highly expressed in low malignant potential and low-grade epithelial ovarian tumors, suggesting that PAX2 induction in ovarian surface epithelium (OSE) may contribute to transformation. Herein, we provide evidence that expression of PAX2 in normal murine OSE cells (mOSE) enhances their proliferation and survival and, with loss of p53, induces tumorigenicity. PAX2 expression in murine ovarian cancer cells enhanced or inhibited tumorigenicity, depending on the model system. In RM cells (mOSE transformed by K-RAS and c-MYC), PAX2 expression inhibited p53 and induced pERK1/2 and COX2, resulting in enhanced angiogenesis and decreased apoptosis of tumors arising from these cells. However, in a murine model of high-grade serous ovarian cancer (STOSE), PAX2 expression improved animal survival by reducing proliferation and metastasis, which correlated with increased Htra1 and decreased COX2. Thus, PAX2 may not be a classical oncogene or tumor suppressor but instead can act in either role by differential regulation of COX2 and/or HTRA1.In 1964, the landmark paper of Marden, Smith, and McDonald established that multiple minor anomalies in newborn infants are associated with an increased risk for major malformations. There were until now no comparable studies in stillbirths. The Wisconsin Stillbirth Service Program (WiSSP) has data regarding nearly 3,000 stillbirths and second trimester losses that have been analyzed for major anomalies and cause of death. One dysmorphologist retrospectively reviewed all 2,397 with usable photographs. Minor anomalies were identified in 1,413 (59%) with 575 of these (41%) having at least one major anomaly. Probability of a major anomaly increased from 7% with no minor anomalies to 15%, 36%, 67%, and 89% with 1, 2, 3, and >33 minor anomalies, respectively. Frequency of minor anomalies was less with lower resolution photographs, but did not show significant differences with maceration or gestational age. The most frequent minor anomalies were infraorbital creases/folds, lowset/posteriorly angulated ears, nuchal edema, flat face, equinovarus foot, camptodactyly, upslanted palpebral fissures, ear antihelix abnormalities (combined), micrognathia/retrognathia, and single transverse palmar crease. Except for infraorbital creases/folds each of these minor anomalies was strongly correlated with major anomalies (P  less then  0.0001). Infraorbital folds were the only anomaly which increased with placental cause of death, and reanalysis with placental causes excluded showed the expected relationship to major anomalies, suggesting that infraorbital folds may be markers for oligohydramnios due to various causes including placental hypoperfusion. Minor anomalies correlate with presence of major anomalies in stillborn fetuses, regardless of gestational age and maceration, and can provide information to guide decisions regarding laboratory testing and other evaluations.Young's moduli of selected amino acid molecular crystals were studied both experimentally and computationally using nanoindentation and dispersion-corrected density functional theory. The Young modulus is found to be strongly facet-dependent, with some facets exhibiting exceptionally high values (as large as 44 GPa). The magnitude of Young's modulus is strongly correlated with the relative orientation between the underlying hydrogen-bonding network and the measured facet. Furthermore, we show computationally that the Young modulus can be as large as 70-90 GPa if facets perpendicular to the primary direction of the hydrogen-bonding network can be stabilized. This value is remarkably high for a molecular solid and suggests the design of hydrogen-bond networks as a route for rational design of ultra-stiff molecular solids.
Since epidemiologic studies suggest that tobacco smoke toxins, e.g. the nicotine-derived nitrosamine ketone (NNK) tobacco-specific nitrosamine, can be a co-factor in alcohol-related brain disease (ARBD), we examined the independent and additive effects of alcohol and NNK exposures on spatial learning/memory, and brain insulin/IGF signaling, neuronal function and oxidative stress.

Adolescent Long Evans rats were fed liquid diets containing 0 or 26% caloric ethanol for 8 weeks. During weeks 3-8, rats were treated with i.p. Sodium acrylate mw NNK (2 mg/kg, 3×/week) or saline. In weeks 7-8, ethanol groups were binge-administered ethanol (2 g/kg; 3×/week). In week 8, at 12 weeks of age, rats were subjected to Morris Water Maze tests. Temporal lobes were used to assess molecular indices of insulin/IGF resistance, oxidative stress and neuronal function.

Ethanol and NNK impaired spatial learning, and NNK ± ethanol impaired memory. Linear trend analysis demonstrated worsening performance from control to ethanol, to NNK, and then esulin/IGF signaling through neuronal growth, survival and plasticity pathways, increase cellular injury and oxidative stress and reduce expression of critical proteins needed for neuronal function.
Epidemiologic studies have demonstrated high rates of smoking among alcoholics, and neuroimaging studies have detected white matter atrophy and degeneration in both smokers and individuals with alcohol-related brain disease (ARBD). These findings suggest that tobacco smoke exposure may be a co-factor in ARBD. The present study examines the differential and additive effects of tobacco-specific nitrosamine (NNK) and ethanol exposures on the structural and functional integrity of white matter in an experimental model.

Adolescent Long Evans rats were fed liquid diets containing 0 or 26% ethanol for 8 weeks. In weeks 3-8, rats were treated with nicotine-derived nitrosamine ketone (NNK) (2 mg/kg, 3×/week) or saline by i.p. injection. In weeks 7-8, the ethanol group was binge-administered ethanol (2 g/kg; 3×/week).

Ethanol, NNK and ethanol + NNK caused striking degenerative abnormalities in white matter myelin and axons, with accompanying reductions in myelin-associated glycoprotein expression. Quantitative RT-PCR targeted array and heatmap analyses demonstrated that ethanol modestly increased, whereas ethanol + NNK sharply increased expression of immature and mature oligodendroglial genes, and that NNK increased immature but inhibited mature oligodendroglial genes. In addition, NNK modulated expression of neuroglial genes in favor of growth cone collapse and synaptic disconnection. Ethanol- and NNK-associated increases in FOXO1, FOXO4 and NKX2-2 transcription factor gene expression could reflect compensatory responses to brain insulin resistance in this model.

Alcohol and tobacco exposures promote ARBD by impairing myelin synthesis, maturation and integrity via distinct but overlapping mechanisms. Public health measures to reduce ARBD should target both alcohol and tobacco abuses.

Management of the pharyngeal pouch has evolved enormously since the first description by Ludlow in 1764 and the first case series by Zenker and Von Ziemssen in 1877. With the introduction of antibiotics, and the advancement of surgical technique with the advent of endoscopic surgery and lasers, current management is vastly different to that in the nineteenth century.

This paper traces the history of pharyngeal pouch management, and discusses the various treatment options and opinions recorded during the nineteenth and twentieth centuries, comparing these with techniques popular today.

Pharyngeal pouch surgery has been associated with significant morbidity, both because of the elderly age of patients typically affected by the condition and because of the surgery itself and potential post-operative complications encountered. The historical development of pharyngeal pouch management and the understanding of pharyngeal pouch pathophysiology are discussed.

Electrocardiographic (ECG) abnormalities are seen in 70%-80% of patients with acute pulmonary embolism (APE). Rarely, APE presents with ST-segment elevation (STE) in leads V1-V4, mimicking ST-segment elevation myocardial infarction (STEMI). Herein, we describe a case of APE presenting with STE in V1-V3, along with a comprehensive review of the literature.

We reviewed Pubmed/Medline indexed articles from 1950 to 2014 reporting cases of APE presenting with STE in V1-V3 or V4 (V1-V3/V4). Cases were analyzed with specific reference to patient demographics, clinical, laboratory, and radiological data, treatment, and outcome.

A total of 12 cases were identified comprising seven males and five females aged between 31 and 64 years. Five cases met the American College of Cardiology/American Heart Association criteria for massive APE due to sustained hemodynamic instability or requirement for inotropic support, and seven met criteria for submassive PE due to right ventricular (RV) dysfunction or elevated troponinuted tomography pulmonary angiogram is warranted for earlier diagnosis of suspected APE, which allow for immediate-rather than delayed-initiation of therapeutic anticoagulant therapy if the diagnosis is confirmed and may avert the need for coronary angiography.
STE in leads V1-V3/V4 in cases with APE identifies a subset of patients who are an intermediate to high risk category. In cases presenting with right precordial lead STE and clinical features that are more suggestive of APE rather than STEMI, a computed tomography pulmonary angiogram is warranted for earlier diagnosis of suspected APE, which allow for immediate-rather than delayed-initiation of therapeutic anticoagulant therapy if the diagnosis is confirmed and may avert the need for coronary angiography.
In previous guidelines, intra-aortic balloon pump (IABP) use was strongly recommended in the treatment of cardiogenic shock in the context of acute myocardial infarction. The recent IABP-SHOCK II trial demonstrated no benefit in short- and medium-term mortality with the use of IABP. It was our objective to evaluate in a real life nationwide population of patients with acute myocardial infarction the impact of IABP in short- and medium-term mortality.

We included patients admitted with acute myocardial infarction in Killip class IV in the first 24 hours, all submitted to urgent coronary angiography. Our study objective was the occurrence of hospital and six-month all-cause mortality.

From the 33,300 patients included in the registry, 4.2% presented with Killip class IV in the first 24 hours and 646 (43.6%) were submitted to urgent coronary angiography. IABP was implanted in 19.8% of these patients. The IABP group was younger, had higher admission heart rate, more multivessel disease and more left main disease.
