The restoration of extensive zygomatic complex defects is a surgical challenge owing to the difficulty of accurately restoring the normal anatomy, symmetry, proper facial projection and facial width. In the present study, an extensive post-traumatic zygomatic bone defect was reconstructed using a custom-made implant that was made with a selective laser melting (SLM) technique. The computer-designed implant had the proper geometry and fit perfectly into the defect without requiring any intraoperative adjustments. A one-year follow-up revealed a stable outcome with no complications.

This study seeks to combine social psychological theories that concentrate on the social-symbolic nature of knowledge theory like the Social Representation Theory (SRT) with a sociological viewpoint that examines group relations and collective identity formation within a specific cultural context. We aim to reach the cultural identity problems by using the concept of cultural identity, as process in a permanent change (Kim Y.Y, 1988, 2007) and the new concept of inter-cultural identity theorized by Y.Y. Kim (2007,1), as a counterpart and extension of cultural identity. We argue that Eastern European culture embedded specific features and common cultural and social bases that differentiated it from other European cultures. Our explanatory argumentation starts from the example of famous Dracula social myth, a myth that is rooted in a model of social representation of minorities in a multi-cultural area.
Visualization of Candidate Division OP3 Cocci in Limonene-Degrading Methanogenic Cultures

Members of candidate division OP3 were detected in 16S rRNA gene clone libraries from methanogenic enrichment cultures that utilized limonene as a carbon and energy source. We developed probes for the visualization of OP3 cells. In situ hybridization experiments with newly designed OP3-specific probes [OP3-565 and Eub-338(VI)] revealed abundant small OP3 cocci attached to larger cells. Syntrophic Deltaproteobacteria, OP3 cells, and methanogens affiliating with Methanoculleus and Methanosaeta formed the limonenedegrading community.

The authors introduced a model of simultaneous switching noise (SSN) coupling between the power/ground plane cavities through cutouts in high-speed and high-density multilayer pack-ages and printed circuit boards (PCBs). Usually, the cutouts are used in multilayer plane structures to isolate the SSN of noisy digital circuits from sensitive analog circuits or to provide multiple voltage levels. The noise-coupling model is expressed in terms of the transfer impedance. The proposed modeling and analysis results are compared with measured data up to 10 GHz to demonstrate the validity of the model. It is demonstrated that the cutout is the major gate for SSN coupling between the plane cavities, and that substantial SSN coupling occurs between the plane cavities through the cutout at the resonant frequencies of the plane cavities. The coupling mechanism and characteristics of the noise coupling, from which a method of suppression of the SSN coupling evaluated was also analyzed and discussed. Proper positioning of the cutout and the devices at each plane cavity achieves significant noise suppression at certain resonant frequencies. The suggested suppression method of the SSN coupling was successfully proved by frequency domain measurement and time domain analysis.

As layout density increases in highly integrated multilayer printed circuit boards (PCBs), the noise that exists in the power distribution network (PDN) is increasingly coupled to the signal traces, and precise modeling to describe the coupling phenomenon becomes necessary. This paper presents a model to describe noise coupling between the power/ground planes and signal traces in multilayer systems. An analytical model for the coupling has been successfully derived, and the coupling mechanism was rigorously analyzed and clarified. Wave equations for a signal trace with power/ground noise were solved by imposing boundary conditions. Measurements in both the frequency and time domains have been conducted to confirm the validity of the proposed model.

Background: MicroRNAs (miRs) are small, non-coding mRNA molecules which regulate cellular processes in tumorigenesis. miRs were discovered in extracellular environment and biological fluids, carrying marks of head and neck squamous cellcarcinoma (HNSCC). They were also identified in abundance in salivary exosomes, in which they are protected by exosomelipid barrier against enzymatic injuries and therefore, the accuracy of exosomal miR-based cancer detection increase. Thissystematic review aimed to reveal and inventorize the most reliable exosomal miRNAs in saliva samples which can be usedas novel biomarkers for early detection of HNSCC. Materials and methods: A systematic literature search, according to PRISMA guideline, was performed on Pubmed andGoogle Academic libraries, based on specific keywords. Original articles published between 2010 and 2021 were selected. The quality of each paper was assessed using the Quality Evaluation Scoring Tool. Results: At the end of selection process, five studies met the inclusion criteria. These studies analyzed twelve salivaryexosomal miRs, presenting different methods of exosome and miR identification for HNSCC detection. A comprehensiveexplanation of the miR pathways of action was drawn and illustrated in this review. Conclusion: Exosomal miRs are promising biomarkers for oral cavity and oropharyngeal cancer detection. miR-10b-5p, miR486-5p, miR-24-3p and miR-200a stand as the most useful ones in saliva sample examination

This paper is dedicated to the study on the external and internal mass transfers of glucose for succinic acid fermentation under substrate and product inhibitions using a bioreactor with stirred bed of immobilized Actinobacillus succinogenes cells. By means of the substrate mass balance for a single particle of biocatalysts, considering the kinetic model adapted for both inhibitory effects, specific mathematical models were developed for describing the profiles of the substrate concentration in the outer and inner regions of biocatalysts and for estimating the substrate mass flows in the liquid boundary layer surrounding the particle and inside the particle. The values of the mass flows were significantly influenced by the internal diffusion velocity and rate of the biochemical reaction of substrate consumption. These cumulated influences led to the appearance of a biological inactive region near the particle center, its magnitude varying from 0 to 5.3% of the overall volume of particles.
