The use of superhydrophobic surfaces(SHSs) is now emerging as an attractive platform for the realization of one-dimensional(1D) nanostructures with potential applications in many nanotechnological and biotechnological *** this purpose, a strict control of the nanostructures size and their spatial arrangement is highly required. However, these parameters may be strongly dependent on the complex evaporation dynamics of the sessile droplet on the SHS. In this work, we investigated the effect of the evaporation dynamics on the size and the spatial arrangement of self-assembled 1D DNA bundles. Our results reveal that different arrangements and bundle size distributions may occur depending on droplet evaporation stage. These results contribute to elucidate the formation mechanism of 1D nanostructures on SHSs.

This systematic review shows the "Status quo" on medical treatment for Peyronie's disease(PD). PD is a connective tissue disorder, characterised by the formation of a fibrotic lesion or plaque in the tunica albuginea, which leads to penile deformity. The aetiology of PD is unknown. Nowadays the most widely accepted hypothesis proposed by Gonzalez-Cadavid et al, is repetitive microvascular injury or trauma to the tunica albuginea. Physicians have proposed several medical alternatives for treatment of this disease with few effective results. Nevertheless, as of today nonsurgical options are currently available, and some of them are able to stabilize or even reduce deformity while improving pain relief and sexual function. A systematic literature search throughout the Medline database was carried out. Thecontrolled vocabulary of the medical subject headings database employs the specific term "penile induratio" for PD. A total of 50 articles on PD were found. Studies were selected based on clinical relevance. The recommended standard of care for PD involves an initial treatment in the acute phase. Several non-operative treatment options have been used. Unfortunately no further substantial, quality evidence on the use of medical therapy currently exits. There is, however, an increasingly enhanced interest in this disorder and basic scientifi c and clinical research will eventually lead to a more effective methodology to study the disease.

The prognostic role of cardiopulmonary exercise test (CPET) in elderly women with chronic heart failure (HF) has not yet been clarified. We assessed the incremental value of CPET variables for risk stratification in female HF patients with preserved or reduced left ventricular ejection fraction (LVEF). We prospectively followed up 131 female HF outpatients aged 72 [interquartile range 62 - 77] years after a symptom limited CPET. 34% had ischemic heart disease and 14% permanent atrial fibrillation, 24% were in NYHA class III. LVEF was 50% [interquartile range 36 - 62], peak oxygen consumption was 11.3 [interquartile range 9.2 - 13.5] ml/kg/min;the slope of the regression line relating ventilation to CO2 output was 33.9 [interquartile range 30.3 - 44.9];40% of patients showed exercise oscillatory breathing during CPET. During a median follow-up of 18 months [interquartile range 8 - 54], overall 39 patients (29.7%) met the combined end-point of cardiovascular mortality or HF admission using a time-to-first event approach. Moderate to severe mitral regurgitation, slope, exercise oscillatory breathing were independently associated to cardiovascular mortality or HF admission. When CPET ventilatory variables were added to clinical and echocardiographic parameters, prediction of the combined point improved significantly (AUC 0.755 (95% CI 0.662 to 0.832) vs 0.634 (95% CI 0.536 to 0.725), p = 0.016). In conclusion, among elderly female HF patients the CPET derived parameters EOB and VE/VCO2 slope emerged as strong prognostic markers, with additive predictive value to clinical and echocardiographic parameters in patients with both reduced and preserved LVEF.

BACKGROUND Contrast-enhanced ultrasound(CEUS)is considered a secondary examination compared to computed tomography(CT)and magnetic resonance imaging(MRI)in the diagnosis of hepatocellular carcinoma(HCC),due to the risk of misdiagnosing intrahepatic cholangiocarcinoma(ICC).The introduction of CEUS Liver Imaging Reporting and Data System(CEUS LI-RADS)might overcome this *** though data from the literature seems promising,its reliability in real-life context has not been well-established *** To test the accuracy of CEUS LI-RADS for correctly diagnosing HCC and ICC in *** CEUS LI-RADS class was retrospectively assigned to 511 nodules identified in 269 patients suffering from liver *** diagnostic standard for all nodules was either biopsy(102 nodules)or CT/MRI(409 nodules).Common diagnostic accuracy indexes such as sensitivity,specificity,positive predictive value(PPV),and negative predictive value(NPV)were assessed for the following associations:CEUS LR-5 and HCC;CEUS LR-4 and 5 merged class and HCC;CEUS LR-M and ICC;and CEUS LR-3 and *** frequency of malignant lesions in CEUS LR-3 subgroups with different CEUS patterns was also ***-rater agreement for CEUS LI-RADS class assignment and for major CEUS pattern identification was *** CEUS LR-5 predicted HCC with a 67.6%sensitivity,97.7%specificity,and 99.3%PPV(Pded benign lesions(only 28.8%of malignancies).In this class,the hypo-hypo pattern showed a much higher rate of malignant lesions(73.3%)than the iso-iso pattern(2.6%).Inter-rater agreement between internal raters for CEUS-LR class assignment was almost perfect(n=511,k=0.94,P<0.001),while the agreement among raters from separate centres was subst
