A systematic review: ABSTRACT The purposes of this article were to review the literature regarding subjective outcomes, objective functional outcomes, and objective sensation return after sensate and/or insensate free flap reconstruction of the oral cavity and oropharynx. Sensate radial forearm and anterolateral thigh free flaps tend to have better static 2-point discrimination and pressure threshold sensitivity than insensate flaps. There is insufficient evidence to draw conclusions on whether sensate flaps improve functional speech and swallowing outcomes measured by videofluoros... περισσότερα »

One-stage reconstruction of tracheal defects with the medial femoral condyle corticoperiosteal-cutaneous free flap: Abstract Background The demanding anatomic and mechanical requirements make the reconstruction of long tracheal defects challenging. Multiple attempts at replacing tracheal segments are described, including the use of autologous, allogeneic, and synthetic tissues. However, the multilayer structure of the trachea and its function as a conduit for air had generally resulted in the use of nonvascularized tissue and/or multistage procedures.

The pathophysiology of monosymptomatic nocturnal enuresis with special emphasis on the circadian rhythm of renal physiology

Abstract Nocturnal polyuria in monosymptomatic nocturnal enuresis (MNE) has so far mainly been attributed to a disturbed circadian rhythm of renal water handling. Low vasopressin levels overnight correlate with absent maximal concentrating activity, resulting in an increased nocturnal diuresis with low urinary osmolality. Therefore, treatment with desmopressin is a rational choice. Unfortunately, 20 to 60 […]

Characterization of individual molecular adsorption geometries by atomic force microscopy: Cu-TCPP on rutile TiO2 (110)

Functionalized materials consisting of inorganic substrates with organic adsorbates play an increasing role in emerging technologies like molecular electronics or hybrid photovoltaics. For such applications, the adsorption geometry of the molecules under operating conditions, e.g., ambient temperature, is crucial because it influences the electronic properties of the interface, which in turn determine the device performance.

Role of a Carboxyl Group in the Adsorption of Zn Porphyrins on TiO2(011)-2×1 Surface

Adsorption of carboxylic-substituted Zn porphyrin molecules (COOH-ZnTPP) on the (011) surface of rutile TiO2 is examined by scanning tunneling microscopy at room temperature. The molecules are either flat, stabilized by the surface defects, or mobile with their movement limited to a reconstruction row of the substrate. Upon increasing the molecular coverage the molecules form ID […]

Electrospray deposition of organic molecules on bulk insulator surfaces

Large organic molecules are of important interest for organic-based devices such as hybrid photovoltaics or molecular electronics. Knowing their adsorption geometries and electronic structures allows to design and predict macroscopic device properties. Fundamental investigations in ultra-high vacuum (UHV) are thus mandatory to analyze and engineer processes in this prospects. With increasing size, complexity or chemical […]

Permanent reduction of dissipation in nanomechanical Si resonators by chemical surface protection

We report on mechanical dissipation measurements carried out on thin (∼100 nm), single-crystal silicon cantilevers with varying chemical surface termination. We find that the 1-2 nm-thick native oxide layer of silicon contributes about 85% to the friction of the mechanical resonance. We show that the mechanical friction is proportional to the thickness of the oxide […]

Multidimensional Approach to the Development of a Mandarin Chinese–Oriented Sound Test: Purpose Because the Ling six-sound test is based on American English phonemes, it can yield unreliable results when administered to non-English speakers. In this study, we aimed to improve specifically the diagnostic palette for Mandarin Chinese users by developing an adapted version of the Ling six-sound test. Method To determine the set of testing sounds, we performed an exhaustive acoustic and statistical analysis in which we considered not only the general acoustic properties but also the ... περισσότερα »

Interactions of Participant Capacities and Sentence Structures: Purpose We asked whether sentence repetition accuracy could be explained by interactions of participant processing limitations with the structures of the sentences. We also tested a prediction of the procedural deficit hypothesis (Ullman & Pierpont, 2005) that adjuncts are more difficult than arguments for individuals with developmental language impairment (DLI). Method Forty-four young adults participated, 21 with DLI. The sentence repetition task varied sentence length and the use of arguments and adjuncts. We also ... περισσότερα »

pH-Triggered Reversible Multiple Protein-Polymer Conjugation Based on Molecular Recognition

Polymer conjugation for protein-based therapeutics has been developed extensively, but it still suffers from conjugation leading to decrease in protein activity and generates complexes with limited diversity due to general classical systems only incorporating one protein per each complex. Here we introduce a site-specific noncovalent protein-polymer conjugation, which can reduce the heterogeneity of the conjugates […]

Although it is necessary for neural development, recent studies suggest a possible link between excess maternal supplemental FA intake and adverse interferences with single-carbon metabolism and neural development. Insufficient FA early in brain development can lead to failure of the neural tube closure, but the consequences of too much intake have not been fully investigated.
