Background Non-syndromic craniosynostosis causes craniofacial asymmetry and may persist after cranioplasty. These postoperative asymmetries are primarily depressions. In some cases, patients may be subjected to pranks and harassment by their peers, affecting their psychosocial development. We propose lipoinjection enriched with adipose stem cells (ASCs) to treat the sequelae of craniosynostosis in the fronto-orbital and temporal complex in cranioplasty patients, with the goal of improving the appearance of the upper third of the face. Methods Twelve children (four boys and eight girls) between 4 and 8 years of age (mean age, 6 years) in the postoperative period after treatment for plagiocephaly, brachycephaly, and trigonocephaly were included, with a follow-up period of 1 to 18 months. Fat tissue was obtained from the lower abdomen, and ASCs were isolated using the Yoshimura technique. Lipoinjection was performed using several mini-approaches to ensure adequate distribution. Results Two different scales were used to evaluate the aesthetic outcomes. At 6 months, three plastic surgeons independent of the study classified the results using a Likert scale. The patients' parents categorized the results using a visual analog scale at 6, 9, and 18 months. R esults were favorable on both scales, as the patients' facial appearance improved and they reported increased happiness and self-esteem due to their remodeled facial appearance. Conclusions We suggest that lipoinjection enriched with ASCs is a good alternative for correcting asymmetry of the fronto-orbital and temporal contour in patients with sequelae of craniosynostosis. This treatment will help boost patients' self-esteem starting at an early age.
Lipoinjection with Adipose Stem Cells for Nasal Modeling: Rhino Cell, a Highly Versatile Alternative
Castro-Govea Yanko,Garcia Garza Jorge Alberto,Vazquez Lara Sergio Eduardo,Gonzalez Cantu Cynthia Minerva,Chacon Moreno Hernan Jesus,Cervantes Kardash Victor Hugo 대한성형외과학회 2023 Archives of Plastic Surgery Vol.50 No.4
It is undeniable that a significant number of patients who want to improve their facial appearance is increasingly interested in nonsurgical procedures. Without a doubt, the use of autologous fat could not be left out as a magnificent alternative for nasal modeling simply because of four influential factors: ease of collection, compatibility, the temporality of the results, and safety. This work describes an innovative alternative technique for nasal modeling using micrografts enriched with adipose-derived mesenchymal stem cells (ASCs). With this technique, fat was collected and divided into two samples, nanofat and microfat. Nanofat was used to isolate the ASCs; microfat was enriched with ASCs and used for nasal modeling. Lipoinjection was performed in a supraperiosteal plane on the nasal dorsum. Through a retrolabial access, the nasal tip and base of the columella were lipoinjected. We consider that nonsurgical nasal modeling using micrografts enriched with ASCs can be an attractive and innovative alternative. This technique will never be a substitute for surgical rhinoplasty. It can be performed in a minor procedure area with rapid recovery and return to the patient’s daily activities the next day. If necessary, the procedure can be repeated.

The 17–4 Precipitation Hardening Stainless Steel (PH SS) manufactured by Selective Laser Melting (SLM) has wide applicationperspectives, but they are limited due to defects and anisotropy. The selection of the appropriate process variablesplays a fundamental part in the microstructure and in the determination of the final mechanical and corrosion properties. The main purpose of this study is to analyze the corrosion behavior, hardness and microstructure of 17–4 PH SS manufacturedby SLM in comparison to the commercial counterparts. The anisotropic behavior was investigated by analyzing themicrostructure–hardness and corrosion interrelationship, both in the surface of the construction platform and in the growthdirection of the element. The corrosion behavior of the SLM 17–4PH SS in its natural state was investigated in relation tothat of the 17–4 PH SS heat treated in a 0.1 M NaCl + 0.5 M H2SO4solution, using three electrochemical techniques. Theresults confirmed that the corrosion resistance of SLM 17–4 PH SS was considerably better than that of the forging, evenafter 60 days of immersion in the test solution. This was attributed to the absence of important manufacturing defects, tothe fine microstructure with an important amount of austenite produced by SLM, and to a small amount of non-metallicinclusions precipitated as a result of the fast cooling and the high speed of solidification associated with the SLM process.

Acceptance and the probiotic viability of aninnovative non-dairy frozen açaí (Euterpe oleracea, Mart.)dessert supplemented and not supplemented with inulinduring a shelf-life of 84 days at −18oC were investigated. Desserts containing and not containing probiotic Lactobacillusacidophilus La-5 and Bifidobacterium animalis Bb-12 andinulin were produced, resulting in 4 mixes of frozen açaí:control (M1), pro (M2), pre (M3), and synbiotic (M4). Sensory acceptability scores and probiotic counts wereobtained during 84 days of storage. Inulin, a key factor forproduct approval, significantly (p<0.05) increased overallproduct acceptance of both M3 and M4, compared withM1. La-5 viability was above 7 log CFU/g for both pro andsynbiotic desserts. Bb-12 counts were above 6 log CFU/gonly for M4. All frozen açaí desserts were suitable forprobiotic delivery and were accepted by consumers. Addition of inulin is recommended both for increasingacceptance and for the synbiotic potential.

Purpose: Turner syndrome is defined as total or partial loss of the second sex chromosome in a phenotypically female patient. Due to the possibility of hidden mosaicism of fragments of the Y chromosome and development of gonadoblastoma, we evaluated the presence of such fragments in 2 tissues with different embryonic origins, peripheral blood lymphocytes (mesoderm), and oral mucosal cells (ectoderm) using multiplex polymerase chain reaction.Methods: DNA samples were collected from 109 patients, and primers for the SRY, TSPY, and AMELX genes were used.Results: We found 14 patients (12.8%) with positive molecular markers for the Y chromosome. The study of tissues of different embryological origin showed the same degree of agreement, sensitivity, and specificity.Conclusion: Oral mucosa cells have a simpler method of collection that is less invasive and requires less time for DNA extraction at a lower cost.
Stabilizing Control of an Unmanned Surface Vehicle Pushing a Floating Load
Rafael Vida Castro Rosario,José Paulo V. S. Cunha,Paula B. Garcia-Rosa 제어·로봇·시스템학회 2020 International Journal of Control, Automation, and Vol.18 No.12
In this paper, the automatic control of a single unmanned surface vehicle (USV) pushing a floating load is developed and theoretically analyzed. This represents a challenging control problem, since the manipulated load is underactuated and its open-loop dynamics is inherently unstable. Thus, a stabilizing controller must be designed. To this end, a scheme that combines partial feedback linearization with local linearization of the remaining nonlinear terms is proposed. Such scheme simplifies the design of a variable structure controller, that has robustness characteristics to parametric uncertainties and matched disturbances. The proposed closed-loop control system has local stability properties. Small-scale experimental results in calm waters, and simulation results, illustrate the performance of the proposed control system.
An approach to solving the forward kinematics of the 5-RPUR (3T2R) parallel manipulator
Jaime Gallardo-Alvarado,Mario A. Garcia-Murillo,Luis D. Aguilera-Camacho,Luis A. Alcaraz-Caracheo,X. Yamile Sandoval-Castro 대한기계학회 2023 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.37 No.3
This work is devoted to simplifying the formulation and solution of the closure equations associated with the forward kinematic problem (FKP) of the 5-RPUR parallel manipulator, a limited-DOF robot able to perform 3T2R motion. The analysis yields a set of eighteen nonlinear equations that are solved numerically through a combination of the homotopy continuation method and the usual Newton-Raphson technique. Unlike existing methods, the proposed approach is easy to follow and can be easily translated into computer codes. Numerical examples are provided with the aim to illustrate the potential and correctness of the proposed method.

Guided with the principles of Lesson Study and Productive Pedagogies as applied to microteaching, this paper discusses the results and conclusions of a series of activities done by some graduate students of De La Salle University, Philippines in an attempt to test the applicability of the lesson ? Sequence and Patterns ? to introduce variables to seventh graders. The post-lesson discussion and a posteriori analysis proved the lesson to be a practical means to address the issue as it was able to put forward discourses and elaborations on possible students` understanding of variables generated through attempts to describe patterns occurring in sequences presented.
