Introduction Magnetic resonance angiography (MRA) with the differential subsampling with cartesian ordering (DISCO) imaging technique is rarely used in anterolateral thigh (ALT) flap. In our series, MRA DISCO imaging technique is used as a tool to customize ALT flaps. The aim of this study was to report the accuracy of cutaneous perforators identif...

Background This study aimed to report the outcomes of mimical reconstruction and aesthetic repair of the nail. Methods When the pigmented bands were more than 1/2 the width of the whole nail, mimical reconstruction of the nail was performed, with a lateral toe pulp island flap covering the wound via the subcutaneous channel. If the pigmented bands...

Background: Previous studies have shown about 25% - 33% of cutaneous melanomas result from melanocytic nevi. Currently, there are no consensus on treatment of the subungual melanocytic nevi with the pigmented band width > 3mm. However, some options change post-operative nail appearance and cannot obtain a well aesthetic outcome. The purpose of this...

Background Equinus of the ankle is a common deformity in spastic cerebral palsy. Achilles tendon lengthening is one of the effective options for the treatment of equinus deformity. Methods In the study, a new stair-shaped Achilles tendon lengthening (ATL) procedure that preserves of the tendon continuity was performed in 28 tendons with equinus de...

In this paper, extremely low frequency band gaps of beam-like inertial amplification metamaterials are investigated based on local resonance theory. Inertial amplification mechanism is proposed to obtain extremely low frequency band gaps by altering geometry parameters of the beam-like structures rather than modulating material properties, which al...

Objective: To investigate and compare the advantages of surgical treatment of ingrown toenail with the traditional Winograd method. Methods: From Aug.2013 to Jun.2015,77 cases (89 toes) with 15-58 years were involved in the study.37 cases (42 toes) were treated with Winograd method and other 40 cases (47 toes) were treated with a method using la...

This paper studies a novel kind of low-frequency broadband acoustic metamaterials with small size based on the mechanisms of negative mass density and multi-cavity coupling. The structure consists of a closed resonant cavity and an open resonant cavity, which can be equivalent to a homogeneous medium with effective negative mass density in a certai...

The influences of fuel dilution, inlet velocity, and gravity on the shape and structure of laminar coflow CH4–air diffusion flames were investigated computationally and experimentally. A series of nitrogen-diluted flames measured in the Structure and Liftoff in Combustion Experiment (SLICE) on board the International Space Station was assessed nume...

Fiber optic terminals and methods for establishing optical connections are disclosed. In one embodiment, a fiber optic terminal is provided that includes a base defining an interior chamber. The fiber optic terminal includes a terminal cover configured to close onto the base. A plurality of fiber routing guides are disposed in the base defining an...

In this study, the influences of gravity and fuel dilution on the structure, stabilization, and sooting tendency of laminar coflow methane-air diffusion flames were investigated both computationally and experimentally. A series of nitrogen-diluted flames measured in the Structure and Liftoff in Combustion Experiment (SLICE) was assessed numerically...

Freshly harvested loquat fruit were pretreated with 50 nl/L 1-methylcyclopropene (1-MCP) for 24 h at 20°C and then stored at 1°C for 35 days to investigate the effect of 1-MCP on fruit nutritive and functional properties. The results show that 1-MCP-treated fruit exhibit a lower incidence of decay and higher levels of total soluble solids, total ti...

In this study, computational and experimental investigations were performed to assess the influence of pressure on flame properties. Coflow methane flames with two levels of nitrogen dilution (35% and 50% nitrogen) were investigated with pressure ranging from 1.0 to 1.5 atm. Computationally, a damped modified Newton's method was used to solve the s...

The luminescent properties of Sr3V2−xPxO8 (0 ⩽ x ⩽ 2), Eu3+ doped Sr2.7Eu0.2V2−yPyO8 (0 ⩽ y ⩽ 2) and Sr3−3zEu2zV0.8P1.2O8 (0 < z ⩽ 0.3) have been investigated. For the Sr3V2−xPxO8 (0 ⩽ x ⩽ 2) samples, the VO43- activation and emission intensity reaches the strongest as x = 1.6. For the Sr2.7Eu0.2V2−yPyO8 (0 ⩽ y ⩽ 2) samples, an appropriate amount o...

The optical spectra have been investigated for a prototypical double exchange ferromagnetic La0.67Ca0.33MnO3 with Mn substituted by V above the paramagnetic–magnetic transition temperature TC. The excitation spectra under the probe wavelength of λem = 473 nm for all samples exhibit two activation bands around 360 and 294 nm, involving an electron t...

The V doped La0.67Ca0.33Mn1−xVxO3 (0 ≤ x ≤ 0.08) samples have been investigated by measuring the resistivity, magnetization, thermoelectric power and thermal conductivity. The V doping lowers the metal–insulator and magnetic transition temperature and enhances the thermoelectric power. The evolution of thermal conductivity with temperature exhibits...

The study was conducted to investigate the effects of heat treatment on flesh leatheriness of cold-stored loquat fruits and the possible mechanisms. Freshly harvested loquat fruits were pre-treated with hot air at 38°C for five hours and then stored at (1±1)°C for 35 days. Fruits firmness, extractable juice rate, the activities of phenylalanine amm...

We studied the cell kinetics of the murine mammary carcinoma MCa-K using iododeoxyuridine (IdUrd) and chlorodeoxyuridine (CldUrd) given at different times as independently detectable labels of S phase cells. The presence of IdUrd and CldUrd, and the amount of DNA were measured by three-colour flow cytometry making it possible to define three subpop...

Solid tumors contain populations of proliferating (P) and quiescent (Q) cells. Shifting between these populations occurs continuously and cells are recruited from quiescence to proliferate (Q-->P) as a result of exogenously applied or endogenous cell depleting stimuli. Direct measurements of the proliferation kinetics of these Q-->P cells in solid...

Abnormal synthesis, secretion, and extracellular matrix incorporation of fibrillin is observed in the majority of fibroblast cell strains obtained from individuals with the Marfan syndrome (>85%). These fibrillin protein abnormalities are due to mutations in the FBN1 gene. We have screened fibroblast cell strains from patients with thoracic aortic...

Dermal fibroblasts from a 13-year-old boy with skeletal features of the Marfan syndrome were used to study fibrillin synthesis and processing. Synthesis and secretion of profibrillin was normal but only half of the secreted profibrillin was converted to fibrillin, an extracellular proteolytic processing that removes a 20 kDa fragment from the prote...

A computer-based Quantitative Basin Analysis System (QBAS) has been developed for the study of sedimentary basins. The QBAS consists of three major components: database, data processing, and modeling.
