Background: As a combination of curve of Spee and curve of Wilson, the Monson sphere reflects the arrangement of teeth in three-dimensional (3D) space. For occlusal analysis, the Monson sphere can provide an important reference for prosthetic reconstructions or orthodontic treatments.
Objectives: The purpose of this study was to generate and investigate the 3-D Monson sphere through a complete digital workflow with intraoral scanning models and custom software.
A self-assembled tetrahedral cage results from two -symmetry building blocks, namely, homooxacalix[3]arene tricarboxylate and uranyl cation, as demonstrated by X-ray crystallography. In the cage, four metals coordinate at the lower rim with the phenolic and ether oxygen atoms to shape the macrocycle with appropriate dihedral angles for tetrahedron formation, whereas four additional uranyl cations further coordinate at the upper-rim carboxylates to finalize the assembly. Counterions dictate the filling and porosity of the aggregates, whereas potassium induces highly porous structures, and tetrabutylammonium yields compact, densely packed frameworks.

The efficiency of far-infrared irradiation (FIR) between 160 °C and 200 °C on the deglycosylation of bioactive compounds in ginseng leaves was analyzed. FIR treatment significantly increased the total polyphenol content (TPC) and kaempferol production from panasenoside conversion.

In the present study, major organic acids, sugar content, enzyme activities, and the expression of related genes were analyzed during fruit development in two loquat cultivars, 'JieFangZhong' (JFZ) and 'BaiLi' (BL). Our results showed that the sugar content increased during fruit development in the two cultivars; however, the organic acid content dramatically decreased in the later stages of fruit development.

Therefore, a novel hydrophilic food-grade hydroxypropyl methylcellulose (HPMC) polymer was added to soybean to prepare a soybean food composite (SFC), in order to improve the soybean's functionality. The SFC was prepared with soybean (95%) plus HPMC (5%) (/) mixes (HSE), as well as 100% soybean extrudate (SE), at 80 °C and 130 °C by a hot melt extrusion (HME) process.

This retrospective study included 151 patients who underwent unenhanced CT before laparotomy for blunt abdominal trauma between January 2011 and December 2013. According to surgical observations, patients were classified as having BHVI/MI (n = 73) or not (n = 78).

Virtual internal hyperspectrum of body surface which can express and properly mix the information of skin's composition and structure was expected to apply in the human disease quick-diagnosis, but the weak detected signal was easily impacted by ambient light and dark current from the instrument, so square wave modulated by chopper disk was proposed to resolve this issue. First, we built the experiment platform, and selected both laser and bromine tungsten lamp as the light source, then compared the virtual hyperspectrum of non-modulated and modulated light on human arm in the environment with artificial interference, and demodulated the modulated signal by FFT method. The experiment result showed that modulation method could effectively eliminate the impact brought by environmental light and dark current and improve the signal to noise ratio (SNR), suggesting a new approach to detect human's weak optical signals.

Purposed to achieve the detection of changes in tissue structure and composition simultaneously by virtual internal hyper-spectrum of body surface (VIHBS), we designed the VIHBS system containing modulated light, translation stage device for data acquisition and spectrometer. In the present study, pork meat as the experimental subject was equally divided into three pieces. One piece was used for a control study, and the others were separately embedded with red filter and injected into highly scattering intralipid to imitate the changes in tissue structure and composition.

Structural characterization of TAPz has shown that its conformation is fluxional in solution but exhibits a dominant 1,3-alternate configuration in the crystalline solid state, wherein its convergent chelating coordination sites are orthogonal to the 120°-angled bridging sites, thus forming a unique multimodal ligand. Compound TAPz reacting with silver, zinc metal centers, and Cu(x)I(x) cluster centers leads to the construction of diverse coordination network structures in 1-5 including honeycomb, Kagomé, α-quartz, and cavity-involved two-dimensional layers.

By means of various spectroscopic methods, the heteracalixaromatics-C(60) dyads and triads obtained have been shown to form intramolecular self-inclusion complexes rather than oligomers or polymers in solution because of a flexible spacer in between the heteracalixaromatic ring and C(60) moiety. The current study, coupled with previous investigations, would provide the guideline for the construction of supramolecular fullerene motifs based on molecular design of the dyads and triads.
