Resumen

In ultrasonography, ultrasound contrast agents (UCAs) that possess high acoustic impedance mismatch with the bulk medium are frequently employed to highlight the borders between tissues by enhanced ultrasound scattering in a clinic. Typically, the most common UCA, microbubble, is generally close in size to a red blood cell (<∼10 μm). These microscale UCAs cannot be directly entrapped into the target cells but generate several orders of magnitude stronger echo signals than the nanoscale ones. And their large containment and high ultrasound responsiveness also greatly facilitate to perform co

Resumen

The important uropathogenProteus mirabilisencodes a record number of chaperone/usher-pathway adhesive fimbriae. Such fimbriae, which are used for adhesion to cell surfaces/tissues and for biofilm formation, are typically important virulence factors in bacterial pathogenesis. Here, the structures of the receptor-binding domains of the tip-located two-domain adhesins UcaD (1.5 Å resolution) and AtfE (1.58 Å resolution) from twoP. mirabilisfimbriae (UCA/NAF and ATF) are presented. The structures of UcaD and AtfE are both similar to the F17G type of tip-located fimbrial receptor-binding domains, a

Resumen

The misalignment in the orbital angular momentum- (OAM-) based system would distort the radiation patterns of twisted beams carrying OAM, consequently making the OAM-based communication infeasible. To tackle the misalignment problem, a radio OAM steering technique based on a uniform circular array (UCA) is illustrated. Subsequently, simulations are conducted to explore the influence of the OAM steering on the OAM mode quality and transmission performance. Furthermore, UCAs working at Ka-band with formulated feeding networks are designed and fabricated to analyze the performance of the OAM stee

Resumen

The application of orthotopic liver transplantation (OLT) for patients with hepatocellular cancer (HCC) necessitates highly selective criteria to maximize survival and to optimize allocation of a scarce resource. The objective of this study was to compare the outcomes of OLT for HCC in patients transplanted under Milan and UCSF criteria. The United Network of Organ Sharing (UNOS) database was queried for patients who had undergone OLT for HCC from 2002 to 2007, and 1,972 patients (Milan criteria,n=1,913; UCSF criteria,n=59) were identified. Patients were stratified by pretransplant criteria (M

Resumen

Background/Aims: Urothelial carcinoma-associated 1 (UCA1) is a recently identified long non coding RNA (lncRNA). However, few studies have explored its role in cardiomyocytes after focal cardiac ischemia reperfusion injury (CIR). Methods: Rat CIR models were established using ligation of the Lower Anterior Descending artery (LAD). Cell apoptosis and reactive oxygen species (ROS) production in cardiac tissues were explored using immunohistochemistry and DHE staining. lncRNA expression patterns were detected using microarray and validated by qPCR. Cell viability and apoptosis were examined using

Abstract OBJECTIVE: Guglielmi detachable coils (GDCs) increasingly are being used to treat unruptured cerebral aneurysms (UCAs). We systematically reviewed the literature to assess the case-fatality and permanent morbidity rates of GDC embolization of UCAs and the postembolization bleeding rate. METHODS: Through a MEDLINE search of the English, Italian, and French literature from January 1990 through December 2002, we retrieved studies on GDC embolization of aneurysms and extracted data on UCAs. Inclusion criteria were: 1) attempted GDC embolization of at least five consecutive patients with U

Resumen

Activators of the CFTR Cl- channel may be useful for therapy of cystic fibrosis. Short-circuit current ( Isc) measurements were done on human bronchial epithelial cells to characterize the best flavone and benzimidazolone CFTR activators identified by lead-based combinatorial synthesis and high-throughput screening. The 7,8-benzoflavone UCcf-029 was a potent activator of Cl- transport, with activating potency (<1 μM) being much better than other flavones, such as apigenin. The benzimidazolone UCcf-853 gave similar Isc but with lower potency (5–20 μM). In combination, the effect induced by m

Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs/miRs) are noncoding RNAs that function as regulators of tumor suppressors and oncogenes. The aim of the present study was to investigate the potential mechanism associated with the involvement of urothelial cancer associated 1 (UCA1) in melanoma. Reverse transcription-quantitative polymerase chain reaction and western blot analysis were performed in order to determine the expression levels of UCA1, miR-143, miR-216b, and hexokinase 2 (HK2) in the melanoma and control groups, as well as the influence of UCA1, miR-143, and miR-216b on the expre

Resumen

Long noncoding RNA urothelial carcinoma-associated 1 (lncRNA UCA1) has gained more attention in recent years due to its oncogenic roles in various cancers. MicroRNA-144 (miR-144) participates in the regulation of the growth of many cancer cells. This study investigated the interaction between lncRNA UCA1 and miR-144 in lung cancer cells. The potential downstream protein of miR-144 was also assessed. Our results found that lncRNA UCA1 was highly expressed in human lung cancer A549, H517, H4006, H1299, and H1650 cells compared to normal embryonic lung WI-38 and HEL-1 cells. Knockdown of lncRNA U

Resumen

Path-planning for uninhabited combat air vehicles (UCAV) is a typically complicated global optimization problem. It seeks a superior flight path in a complex battlefield environment, taking into various constraints. Many swarm intelligence (SI) algorithms have recently gained remarkable attention due to their capability to address complex optimization problems. However, different SI algorithms present various performances for UCAV path-planning since each algorithm has its own strengths and weaknesses. Therefore, this study provides an overview of different SI algorithms for UCAV path-planning

Resumen

ABSTRACTUnmanned Combat Aerial Vehicles (UCAVs) are believed by many to be the future of aerial strike/reconnaissance capability. This belief led to the design of the UCAV 1303 by Boeing Phantom Works and the US Airforce Lab in the late 1990s. Because UCAV 1303 is expected to take on a wide range of mission roles that are risky for human pilots, it needs to be highly adaptable. Geometric morphing can provide such adaptability and allow the UCAV 1303 to optimise its physical feature mid-flight to increase the lift-to-drag ratio, manoeuvrability, cruise distance, flight control, etc. This capabi

We evaluated the usefulness of various parameters in predicting the prognosis of ulcerative colitis. The records of 73 patients with ulcerative colitis were examined retrospectively. Patients were divided into two groups according to whether they had received only 5-aminosalicylic acid (5-ASA; n = 26) or glucocorticoids and/or azathioprine with or without 5-ASA ( n = 47). The disease extent, endoscopic activity and ulcerative colitis activity index (UCAI) before therapy were recorded, together with the disease outcome.

Resumen

Three-dimension path planning for uninhabited combat air vehicle (UCAV) is a complicated high-dimension optimization problem, which primarily centralizes on optimizing the flight route considering the different kinds of constrains under complicated battle field environments. A new hybrid metaheuristic differential evolution (DE) and cuckoo search (CS) algorithm is proposed to solve the UCAV three-dimension path planning problem. DE is applied to optimize the process of selecting cuckoos of the improved CS model during the process of cuckoo updating in nest. The cuckoos can act as an agent in s
