A series of novel polyimidothioethers (PITEs) and the respective polymer hybrids of titania or zirconia with fantastic thermal stability and optical properties have been successfully prepared. These colorless PITEs with high transparency were synthesized by Michael polyaddition from commercially available dithiol and bismaleimides monomers. The PITE with sulfide and hydroxyl groups (S-OH) and the corresponding hybrid films declare ultra-lowest birefringence value of 0.002 and tunable refractive index (1.65-1...

The generation of subwavelength spots smaller than the Abbe diffraction limit has attracted great interest due to the various applications in many fields, such as high-density optical data storage and particle manipulation. Planar optics that can miniaturize conventional refractive optics have become increasingly attractive. In this work, we first formed a subwavelength bright spot and a three-dimensional optical trap under the illumination of an azimuthally polarized (AP) beam by only a single planar element, a spiral zone plate (SZP)...

E A Barbosa, L F G Dib
A simple refractometer using a reflective diffraction grating immersed in the test liquid is developed and its performance is studied. Due to the dependence of the light wavelength on the refractive index, determining the angle of the diffracted beam provides the refractive index of the liquid. The glass cell containing the test liquid is cylindrical, and the grating plane is parallel to the cylinder symmetry axis. The light beam normally impinges on the cell front wall and reaches the center of the grating so that the diffracted beam leaves the cell without being deviated by refraction...

BACKGROUND: Elderly women are at high risk of coronary heart disease (CHD) and heart failure. High-sensitivity assays allow detection of cardiac troponin I (hsTnI) well below diagnostic cutoffs for acute coronary syndrome. We investigated the association between these levels with future cardiac events in community-based ambulant white women aged over 70 years initially recruited for a 5-year randomized, controlled trial of calcium supplements. METHODS AND RESULTS: This was a prospective study of 1081 elderly women without clinical CHD at baseline (1998) or hsTnI above the diagnostic cutoffs for acute coronary syndrome with 14...

The present study explored the concept of tolerance for child distress in 46 children (ages 5-8), along with their mothers and fathers, who received family-based CBT for OCD. The study sought to describe baseline tolerance, changes in tolerance with treatment, and the predictive impact of tolerance on symptom improvement. Tolerance was rated by clinicians on a single item and the CY-BOCS was used to measure OCD severity. Descriptive results suggested that all participants had some difficulty tolerating the child's distress at baseline while paired t tests indicated large improvements were made over treatment (d = 1...

The present work aims to evaluate the effect of an acid extraction as well as a combined enzymatic-chemical extraction on structural, thermal and antioxidant properties of the sulphated polysaccharide 'ulvan' from the green seaweed Ulva lactuca. Structural characterization by FTIR and NMR spectroscopies showed the typical peaks of ulvan, namely, uronic acids, rhamnose and sulphate. FTIR analysis revealed that the extraction procedures were able to maintain ulvan structure. Despite differences in the extraction procedures, (13)C NMR spectra were globally similar, proving a comparable chemical structure of ulvans...

Reconstruction of an aesthetically acceptable and functional upper lip requires a careful consideration of the transverse and vertical soft tissue, muscle and skin, deficiency. This review focuses on the reconstructive aspects of the upper lip.The functional anatomy of the upper lip is considerably complex and includes paired muscles in addition to the orbicularis, elevators of both the upper lip and commissure. The muscular action of facial expression recruits different sets of these paired muscles. Unlike the aesthetic uniform appearance of the lower lip commissure to commissure, the upper lip aesthetics can be divided into a central, the philtrum unit, and a lateral upper lip unit...

Cerebral malaria (CM) is the most severe manifestation of human malaria yet is still poorly understood. Mouse models have been developed to address the subject. However, their relevance to mimic human pathogenesis is largely debated. Here we study an alternative cerebral malaria model with an experimental Plasmodium berghei Keyberg 173 (K173) infection in Sprague Dawley rats. As in Human, not all infected subjects showed cerebral malaria, with 45% of the rats exhibiting Experimental Cerebral Malaria (ECM) symptoms while the majority (55%) of the remaining rats developed severe anemia and hyperparasitemia (NoECM)...

The inhalation of zinc oxide nanoparticles (nZnO) may induce systemic diseases, damages to the alveolar epithelium and inflammatory response to endothelial cells. In this work the use of an in vitro air-blood barrier (ABB) model provided a tool to elucidate the biological mechanisms underlying the potential effects of inhaled nanoparticles (NPs). The ABB model used is composed of a Transwell co-culture of a lung epithelial cell line (NCI-H441) and an immortalized pulmonary microvascular endothelial cell line (HPMEC-ST1...

BACKGROUND: Traffic-related injuries are the leading fatal injury among children in the US, but no published study compares the different types of traffic-related pediatric injuries to date. Thus, this study aims to examine the10 year trend of traffic-related injury among children at a pediatric hospital and to assess if there were differences in injury mechanism. METHODS: All data were drawn from a Level-1 Pediatric Trauma center in North Texas 2005-2014. Demographic characteristics, length of hospitalization (LOS) and patient type were included...

The image of a simple phase object produced by a round lens with a Foucault or Hilbert phase plate can be determined with Abbe imaging theory and a 2D transform expressed in cylindrical coordinates. The contributions to the image amplitude from a uniform disc object and an azimuthally varying plate can then be distinguished and their phases relative to the incident wave can be compared. It appears that the usual choice of added phase for a Hilbert plate causes the image of a weak disc object to vanish as the plate edge approaches the axis, but a different choice of plate thickness can enable a weak phase object to provide a linear contribution to image intensity...

The extraction of abstract structures from speech (or from gestures in the case of sign languages) has been claimed to be a fundamental mechanism for language acquisition. In the present study we registered the neural responses that are triggered when a violation of an abstract, token-independent rule is detected. We registered ERPs while presenting participants with trisyllabic CVCVCV nonsense words in an oddball paradigm. Standard stimuli followed an ABB rule (where A and B are different syllables). Importantly, to distinguish neural responses triggered by changes in surface information from responses triggered by changes in the underlying abstract structure, we used two types of deviant stimuli...

Importance: The blood supply pattern of the partial-thickness musculomucosal pedicle flaps is different from the traditional Abbe flap. The arterial blood supply and venous drainage are highly reliable during clinical practice. Objective: To describe the reconstruction of the philtrum in the cross-lip flap transfer using nasolabial muscle tension line group reconstruction. Design, Setting, and Participants: From January 1, 2014, through June 31, 2015, a total of 6 patients with upper lip defect were treated with philtrum reconstruction in the same stage of the split cross-lip flap transfer at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China...

Coherent X-ray diffraction imaging at symmetric hhh Bragg reflections was used to resolve the structure of GaAs/In0.15Ga0.85As/GaAs core-shell-shell nanowires grown on a silicon (111) substrate. Diffraction amplitudes in the vicinity of GaAs 111 and GaAs 333 reflections were used to reconstruct the lost phase information. It is demonstrated that the structure of the core-shell-shell nanowire can be identified by means of phase contrast. Interestingly, it is found that both scattered intensity in the (111) plane and the reconstructed scattering phase show an additional threefold symmetry superimposed with the shape function of the investigated hexagonal nanowires...

The limits of conventional light microscopy ("Abbe-Limit") depend critically on the numerical aperture (NA) of the objective lens. Imaging at large working distances or a large field-of-view typically requires low NA objectives, thereby reducing the optical resolution to the multi micrometer range. Based on numerical simulations of the intensity field distribution, we present an illumination concept for a super-resolution microscope which allows a three dimensional (3D) optical resolution around 150 nm for working distances up to the centimeter regime...

We report here the clinical, hematological and molecular data in a 50-year-old patient with β-thalassemia intermedia (β-TI) caused by a homozygous β(+) mutation on the β-globin gene polyadenylation (polyA) signal (AATAAA>AAAAAA). β Haplotype analysis was accomplished by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Haplotype and framework analysis showed that this mutation is associated with the [- - - - + + +] β haplotype and framework 1 (CCGCT) (FW1). This mutation was previously reported in the heterozygous state in association with the codon 9 (+TA) mutation in a β-TI patient originating from Tunisia...

BACKGROUND: Tunic is a cellulosic, integumentary matrix found in tunicates (Subphylum Tunicata or Urochordata). The tunics of some ascidian species and pelagic tunicates, such as salps, are nearly transparent, which is useful in predator avoidance. Transparent materials can be detected visually using light reflected from their surfaces, with the different refractive indices between two media, i.e., tunic and seawater, being the measure of reflectance. A larger difference in refractive indices thus provides a larger measure of reflectance...
