Published: March 2021

O mundo está se transformando rapidamente, forçando organizações a adaptarem seus processos para conseguir responder com agilidade a essas mudanças constantes. No cenário de gerenciamento de projetos, novas metodologias estão cada vez mais presentes, trazendo uma abordagem mais ágil e enxuta. Nesse contexto, o gerente de projetos com autoridade formal sobre a equipe está aos poucos dando lugar a um líder que atua mais como um facilitador, removendo obstáculos e promovendo a colaboração e o aprendizado contínuo. Assim, o objetivo deste artigo consiste em comparar as competências consideradas mais importantes para um gestor de projetos que atua predominantemente com metodologias Tradicionais e o líder de projetos que utiliza abordagens Ágeis. Para tal, foi realizada uma survey, utilizando um questionário online, submetido a profissionais que atuam em projetos. As 142 respostas válidas recebidas foram submetidas a análises estatísticas paramétricas por meio de análise de correspondência e de perfis, bem como não paramétricas, utilizando o método de coeficiente de correlação de postos de Kendall. As cinco competências consideradas mais importantes foram as mesmas para os dois grupos, mas ordenadas de maneira distinta. São elas: Integridade e Confiabilidade Pessoal, Comunicação Pessoal, Trabalho em Equipe, Estratégia e Relacionamentos e Engajamento. As análises estatísticas não permitiram concluir categoricamente que existem diferenças na percepção de importância das competências pelos profissionais que trabalham com metodologias Ágeis e Tradicionais, abrindo uma discussão bastante promissora sobre a maneira como essas novas abordagens estão sendo incorporadas pelas organizações e percebidas por seus profissionais.

Aims: The aim of the study was to estimate the prevalence and risk factors of diabetes mellitus among adult population of Albaha region, Saudi Arabia and to identify the diabetic risk clusters among Saudi population using various cluster analysis techniques.
Study Design: Cross-sectional observation and Hierarchal cluster analyses.
Place and Duration of Study: The study was conducted in three different cities of the Albaha region, Saudi Arabia including Albaha, AlAqiq and Baljurashi among Saudi adults 15 years of age or above. The study was carried out from April 2019 to May 2019.
Methodology: The first part of the research was a random cross-sectional observational diabetic risk factors screening using a structured questionnaire among adult volunteers of the Albaha region. The second part constituted a multiple cluster analysis technique performed to identify the diabetic risk factors from 13 regions of Saudi Arabia, clustered into five main regions, using NCSS software.
Results: In the first part, the risk factors identified among non-diabetic participants showed a significant association with the development of diabetes mellitus, particularly physical inactivity (49.12%), hypertension (41.15%), and high body mass index (19.03%). Likewise, in 11.54% of diabetic patients, elevated body mass index (30.51%), hypertension (27.12%) and physical inactivity (55.93%), which could be associated with diabetic complications. In the second part, the three forms of cluster analyses (the agglomerate hierarchical cluster, clustered heat map and K means clustering analysis) identified physical inactivity and high body mass index as key risk factors which are connected to all other risk factors among the total of 213591 volunteers.
Conclusion: Increased prevalence of diabetes and risk of developing diabetes mellitus in the Kingdom require substantial education and training programs to counsel volunteers on all aspects of self-care. Our data provides a robust evidence to establish diabetic counseling through regular diabetes awareness program that can reduce the risk of developing diabetes mellitus.
Facial Reanimation of the Eye Using Neurovascularised Flap of Platysma
Authors: Lim Grace Hui Chin , McLaughlin Kealan , Lim Joanne Hui Yee 
Published: March 2021

Background: Dynamic reanimation is usually required to restore blink function in patients with chronic facial paralysis. In which case, platysma myocutaneous flap (PMF) is a good choice compared to gracilis flap. Platysma is a thin, pliable flap with matching skin colour to the eyelids. Despite this, it is underused.
Aim: To investigate the neurovasculature of platysma in order to find a common “window” containing nerves and blood vessels supply which is present in every individual. This will aid the plastic surgeons to reconstruct the neurovasculature of the flap for grafting onto the eyelids.
Methods: 3 fresh cadaver necks were dissected from 1 males and 2 females, aged 75-88 years old; (n=6 platysmas). 43 squared specimens (measuring 1.5cm x 1.5cm) surrounding any potential neurovascular structures were cut out, processed and analysed under high power microscope to confirm the presence of nerves and blood vessels. We also reviewed literature dated from 1999 to 2011.
Results: From the literature reviewed, the authors concluded that PMF provided excellent functional and aesthetic outcome. In this study, we discovered a “window” flap (ranging from "2.5cm x 3cm‟ to "8cm x 10cm‟) bilaterally on each cadaver. This window is supplied by submental branch of facial artery, drained by facial vein, anterior and external jugular veins, and extensively innervated by cervical branch of facial nerve.
Conclusion: We strongly advocate the use of PMF “window” by plastic surgeons in dynamic eyelids reanimation.

AbstractBackgroundInflammation in chronic active lesions occurs behind a closed blood–brain barrier and cannot be detected with MRI. Activated microglia are highly enriched for iron and can be visualized with quantitative susceptibility mapping (QSM), an MRI technique used to delineate iron.ObjectiveTo characterize the histopathological correlates of different QSM hyperintensity patterns in MS lesions.MethodsMS brain slabs were imaged with MRI and QSM, and processed for histology. Immunolabeled cells were quantified in the lesion rim, center, and adjacent normal‐appearing white matter (NAWM). Iron+ myeloid cell densities at the rims were correlated with susceptibilities. Human‐induced pluripotent stem cell (iPSC)‐derived microglia were used to determine the effect of iron on the production of reactive oxygen species (ROS) and pro‐inflammatory cytokines.ResultsQSM hyperintensity at the lesion perimeter correlated with activated iron+ myeloid cells in the rim and NAWM. Lesions with high punctate or homogenous QSM signal contained no or minimally activated iron− myeloid cells. In vitro, iron accumulation was highest in M1‐polarized human iPSC‐derived microglia, but it did not enhance ROS or cytokine production.ConclusionA high QSM signal outlining the lesion rim but not punctate signal in the center is a biomarker for chronic inflammation in white matter lesions.
Photostrictive Effect: Characterization Techniques, Materials, and Applications
Authors: Chen Chen , Yi Zhiguo 
Published: March 2021

AbstractPhotostrictive effect exhibits a fascinating ability to directly convert light into mechanical strain, which enables a facile and straightforward approach to realize the wireless and remote control of the micro‐electromechanical systems (MEMS). It provides a great potential to upgrade the existing electric‐driven mechanical devices to optomechanical devices by replacing or integrating electrostriction, piezoelectric effect, or magnetostriction. Although this effect can be dated back to the 1960s, it should not be overlooked as a unique photophysical phenomenon. Especially in the passing decade, it has regained widespread attention, triggered by the emerging characterization techniques and new material systems, as well as the booming progress of MEMS. The recent progress of this fast‐growing field is summarized by emphasizing the up‐to‐date characterization techniques and several new material systems. Furthermore, the potential applications of the photostrictive effect are also comprehensively reviewed. It is hoped that this article will promote the development of photostrictive effect, to not only deepen the research on the underlying mechanisms, but also accelerate the exploration of high‐performance photostrictive materials, so as to meet the upcoming challenges faced by light as a major energy source in the foreseeable future.

AbstractVarious materials are utilized as artificial substitutes for bone repair. In this study, a silk fibroin (SF) hydrogel reinforced by short silica nanoparticles (SiNPs)‐distributed‐silk fibroin nanofibers (SiNPs@NFs), which exhibits a superior osteoinductive property, is fabricated for treating bone defects. SF acts as the base part of the composite scaffold to mimic the extracellular matrix (ECM), which is the organic component of a native bone. The distribution of SiNPs clusters within the composite hydrogel partially mimics the distribution of mineral crystals within the ECM. Incorporation of SiNPs@NFs enhances the mechanical properties of the composite hydrogel. In addition, the composite hydrogel provides a biocompatible microenvironment for cell adhesion, proliferation, and osteogenic differentiation in vitro. In vivo studies confirm that the successful repair is achieved with the formation of a large amount of new bone in the large‐sized cranial defects that are treated with the composite hydrogel. In conclusion, the SiNPs@NFs‐reinforced‐hydrogel fabricated in this study has the potential for use in bone tissue engineering.

AbstractSystems for “protein transduction,” intracellular delivery of functional proteins, are needed to address deliverability challenges of protein therapeutics. However, in vivo protein transduction remains challenging because of instability in serum, extracellular protease digestion and rapid excretion from the bloodstream. Here, a magnetically guided in vivo protein transduction using magnetic nanogel chaperone (MC) composed of iron oxide nanoparticles and a polysaccharide nanogel, a protein carrier inspired by “catch and release” mechanisms of molecular chaperones is demonstrated. The MC system enables efficient delivery of anti‐cancer proteins, saporin and RNaseA, into cultured tumor lines and inhibits cell proliferation, mainly via apoptosis. Magnetic in vivo protein transduction via intravenous whole body administration is demonstrated in a fibrosarcoma model. By in vivo optical imaging, MC accumulated in tumor tissues under magnetic field three times more than without irradiation. With subcutaneous injection, saporin is delivered by MC to the cytoplasm in magnetically targeted tissues. In an oral cancer model, MC‐delivered magnetically targeted saporin decreased tumor volume without significant body weight changes and no regrowth of tumor at 3 months after complete regression. Protein transduction with MC shows promise for cancer therapeutics and, potentially, for regenerative medicine and other biomedical applications.

AbstractThe never‐ending struggle against counterfeit demands the constant development of security labels and their fabrication methods. This study demonstrates a novel type of security label based on downconversion photoluminescence from erbium‐doped silicon. For fabrication of these labels, a femtosecond laser is applied to selectively irradiate a double‐layered Er/Si thin film, which is accomplished by Er incorporation into a silicon matrix and silicon‐layer crystallization. The study of laser‐induced heating demonstrates that it creates optically active erbium centers in silicon, providing stable and enhanced photoluminescence at 1530 nm. Such a technique is utilized to create two types of anti‐counterfeiting labels. The first type is realized by the single‐step direct laser writing of luminescent areas and detected by optical microscopy as holes in the film forming the desired image. The second type, with a higher degree of security, is realized by adding other fabrication steps, including the chemical etching of the Er layer and laser writing of additional non‐luminescent holes over an initially recorded image. During laser excitation at 525 nm of luminescent holes of the labels, a photoluminescent picture repeating desired data can be seen. The proposed labels are easily scalable and perspective for labeling of goods, securities, and luxury items.

AbstractLayered 2D semiconductors have been widely exploited in photodetectors due to their excellent electronic and optoelectronic properties. To improve their performance, photogating, photoconductive, photovoltaic, photothermoelectric, and other effects have been used in phototransistors and photodiodes made with 2D semiconductors or hybrid structures. However, it is difficult to achieve the desired high responsivity and linear photoresponse simultaneously in a monopolar conduction channel or a p–n junction. Here, dual‐channel conduction with ambipolar multilayer WSe2 is presented by employing the device concept of dual‐gate phototransistor, where p‐type and n‐type channels are produced in the same semiconductor using opposite dual‐gating. It is possible to tune the photoconductive gain using a vertical electric field, so that the gain is constant with respect to the light intensity—a linear photoresponse, with a high responsivity of ≈2.5 × 104 A W−1. Additionally, the 1/f noise of the device is kept at a low level under the opposite dual‐gating due to the reduction of current and carrier fluctuation, resulting in a high detectivity of ≈2 × 1013 Jones in the linear photoresponse regime. The linear photoresponse and high performance of the dual‐gate WSe2 phototransistor offer the possibility of achieving high‐resolution and quantitative light detection with layered 2D semiconductors.
