Non-melanoma skin cancers: physio-pathology and role of lipid delivery systems in new chemotherapeutic treatments.

Non-melanoma carcinoma has high incidence rates and has two most common subtypes: basal cell carcinoma and squamous cell carcinoma. This type of carcinoma is usually not fatal; however, it can destroy sensory organs such as the nose, ears, and lips. The treatment of these injuries using non-invasive methods is thus strongly recommended. Some treatments for non-melanoma carcinoma are already well defined, such as surgery, cryosurgery, curettage and electrode section, and radiotherapy; however, these conventional treatments cause inflammation and scarring. In the non-surgical treatment of non-melanoma carcinoma, the topical administration of chemotherapeutic drugs contributes for an effective treatment with reduced side effects. However, the penetration of anticancer drugs in the deeper layers of the skin is required. Lipid delivery systems (liposomes, solid lipid nanoparticles, nanostructured lipid carriers) have been developed to overcome epidermal barrier of the skin and to allow the drugs to reach tumor cells. These lipid nanoparticles contribute to control the release profile of the loaded chemotherapeutic drugs, maintaining their stability and increasing death of tumor cells. In this review, the characteristics of non-melanoma carcinoma will be discussed, describing the main existing treatments, together with the contribution of lipid delivery systems as an innovative approach to increase the effectiveness of topical therapies for non-melanoma carcinomas.

Current Microscopy Strategies to Image Fungal Vesicles: From the Intracellular Trafficking and Secretion to the Inner Structure of Isolated Vesicles.

Extracellular vesicles (EVs) are nano-sized structures that play important roles in a variety of biological processes among members of the Eukaryota domain. They have been studied since the 1940s and a broader use of different microscopy techniques to image either isolated vesicles or vesicles within the intracellular milieu (trafficking) has been limited by their nanometric size, usually below the resolution limit of most standard light microscopes. The development of genetically encoded fluorescent proteins and fluorescent probes able to switch between "on" and "off" states, as well the improvement in computer-assisted microscopy, photon detector devices, illumination designs, and imaging strategies in the late Twentieth century, boosted the use of light microscopes to provide structural and functional information at the sub-diffraction resolution, taking advantage of a nondestructive analytical probe such light, and opening new possibilities in the study of life at the nanoscale. As well, traditional and novel electron microscopy techniques have been widely used in the characterization of subcellular compartments, either isolated or in situ, providing a comprehensive understanding of their functional role in many cellular processes. Here, we present basic aspects of some of these techniques that have already been applied and their potential application to the study of fungal vesicles.

Commercially Relevant Orthogonal Multi-Component Supramolecular Hydrogels for Programmed Cell Growth.

This study reports the ability of synthetically simple, commercially viable sugar-derived 1,3:2,4-dibenzylidenesorbitol-4',4"-diacylhydrazide (DBS-CONHNH2 ) to support cell growth. Simple mixing and orthogonal self-sorting can formulate heparin, agarose, and heparin-binding micelles into these gels-easily incorporating additional function. Interestingly, the components used in the gel formulation, direct the ability of cells to grow, meaning the chemical programming of these multi-component gels is directly translated to the biological systems in contact with them. This simple approach has potential for future development in regenerative medicine.

Multi-component hybrid hydrogels - understanding the extent of orthogonal assembly and its impact on controlled release.

This paper reports self-assembled multi-component hybrid hydrogels including a range of nanoscale systems and characterizes the extent to which each component maintains its own unique functionality, demonstrating that multi-functionality can be achieved by simply mixing carefully-chosen constituents. Specifically, the individual components are: (i) pH-activated low-molecular-weight gelator (LMWG) 1,3;2,4-dibenzylidenesorbitol-4',4''-dicarboxylic acid (DBS-COOH), (ii) thermally-activated polymer gelator (PG) agarose, (iii) anionic biopolymer heparin, and (iv) cationic self-assembled multivalent (SAMul) micelles capable of binding heparin. The LMWG still self-assembles in the presence of PG agarose, is slightly modified on the nanoscale by heparin, but is totally disrupted by the micelles. However, if the SAMul micelles are bound to heparin, DBS-COOH self-assembly is largely unaffected. The LMWG endows hybrid materials with pH-responsive behavior, while the PG provides mechanical robustness. The rate of heparin release can be controlled through network density and composition, with the LMWG and PG behaving differently in this regard, while the presence of the heparin binder completely inhibits heparin release through complexation. This study demonstrates that a multi-component approach can yield exquisite control over self-assembled materials. We reason that controlling orthogonality in such systems will underpin further development of controlled release systems with biomedical applications.

Effect of buffer at nanoscale molecular recognition interfaces - electrostatic binding of biological polyanions.

We investigate the impact of an over-looked component on molecular recognition in water-buffer. The binding of a cationic dye to biological polyanion heparin is shown by isothermal calorimetry to depend on buffer (Tris-HCl > HEPES > PBS). The heparin binding of self-assembled multivalent (SAMul) cationic micelles is even more buffer dependent. Multivalent electrostatic molecular recognition is buffer dependent as a result of competitive interactions between the cationic binding interface and anions present in the buffer.

Emergence of highly-ordered hierarchical nanoscale aggregates on electrostatic binding of self-assembled multivalent (SAMul) cationic micelles with polyanionic heparin.

We report three surfactants, with cationic N,N-di-(3-aminopropyl)-N-methylamine (DAPMA) head groups and aliphatic chains connected via an amide linkage, and investigate their ability to self-assemble and bind polyanionic heparin - a process of potential clinical importance in coagulation control. Modifying the hydrophobic chain length tunes the self-assembly event, with C16-DAPMA having the lowest critical micelle concentration and also being the optimal heparin binder. Remarkably highly structured hierarchical nanoscale aggregates are formed on binding between the spherical cationic micelles and linear polyanionic heparin. C14-DAPMA and C16-DAPMA yield organized polycrystalline assemblies as observed by transmission electron microscopy (TEM), predicted in solution by mesoscale simulations and characterized by small-angle X-ray scattering (SAXS). This confirms that the micelles remain intact during the hierarchical assembly process and become packed in a face-centered cubic manner. The nanoscale assembly formed by C16-DAPMA showed the highest degree of order. Importantly, these studies indicate the impact of hydrophobic modification on self-assembly and heparin binding, demonstrate remarkably high stability of these self-assembled micelles even when forming strong electrostatic interactions with heparin, and provide structural insights into nanoscale hierarchical electrostatic assemblies.

Quantitative transportation assessment in simulated curved canals after large apical preparations

Aim: To evaluate the ability of rotary (ProTaper Universal [PTU] and ProTaper Next [PTN]), reciprocating (Reciproc [R] and WaveOne [WO]) and adaptive (Twisted File Adaptive [TFA]) systems in maintaining the original canal profile in straight and curved parts after apical preparations up to size 40. Methods: Resin blocks with simulated curved canals were randomly assigned to five groups: PTU, PTN, R, WO and TFA. Images were captured from each block before and after canal preparation (n=10). Assessment of canal transportation was obtained for the straight and curved parts of the canal. ANOVA followed by Tukey's test was used (α = 5%). Results: Transportation values were increased at the curved part (P = .00). For both canal levels, TFA system induced the lowest mean of canal transportation followed by PTN, R, WO and PTU systems. At the straight portion, transportation for R and TFA systems were similar (P > .05), and these values were significantly lower than for WO, PTN and PTU (P = .00). At the curved portion, TFA resulted in less canal transportation, followed by PTN, R, WO and PTU systems (P = .00). Conclusions: TFA system produced less canal transportation than other systems tested during large apical preparations. (AU)

Quantitative transportation assessment in curved canals prepared with an off-centered rectangular design system.

The purpose of this study was to assess the ability of an off-centered rectangular design system [ProTaper Next (PTN)] to maintain the original profile of the root canal anatomy. To this end, ProTaper Universal (PTU), Reciproc (R) and WaveOne (WO) systems were used as reference techniques for comparison. Forty clear resin blocks with simulated curved root canals were randomly assigned to 4 groups (n = 10) according to the instrumentation system used: PTN, PTU, R and WO. Color stereomicroscopic images of each block were taken before and after instrumentation. All image processing and data analysis were performed with an open source program (Fiji v.1.47n). Evaluation of canal transportation was obtained for two independent regions: straight and curved portions. Univariate analysis of variance and Tukey's Honestly Significant Difference test were performed, and a cut-off for significance was set at α = 5%. Instrumentation systems significantly influenced canal transportation (p = 0.000). Overall, R induced significantly lower canal transportation compared with WO, PTN and PTU (p = 0.000). The curved portion displayed superior canal transportation compared to the straight one (p = 0.000). The significance of the difference among instrumentation systems varied according to the canal level evaluated (p = 0.000). In its straight portion, R and WO exhibited significantly lower transportation than PTN; whereas in the curved portion, R produced the lowest deviation. PTU exhibited the highest canal transportation at both levels. It can be concluded that PTN produced less canal transportation than PTU and WO; however, R exhibited better centering ability than PTN.

Electrostatic binding of polyanions using self-assembled multivalent (SAMul) ligand displays - structure-activity effects on DNA/heparin binding.

This paper reports that modifying the ligands in self-assembled multivalent (SAMul) displays has an impact on apparent binding selectivity towards two nanoscale biological polyanions - heparin and DNA. For the nanostructures assayed here, spermidine ligands are optimal for heparin binding but spermine ligands are preferred for DNA. Probing subtle differences in such nanoscale binding interfaces is a significant challenge, and as such, several experimental binding assays - competition assays and isothermal calorimetry - are employed to confirm differences in affinity and provide thermodynamic insights. Given the dynamic nature and hierarchical binding processes involved in SAMul systems, we employed multiscale modelling to propose reasons for the origins of polyanion selectivity differences. The modelling results, when expressed in thermodynamic terms and compared with the experimental data, suggest that DNA is a shape-persistent polyanion, and selectivity originates only from ligand preferences, whereas heparin is more flexible and adaptive, and as such, actively reinforces ligand preferences. As such, this study suggests that inherent differences between polyanions may underpin subtle binding selectivity differences, and that even simple electrostatic interfaces such as these can have a degree of tunability, which has implications for biological control and regulation on the nanoscale.

1,3:2,4-Dibenzylidene-D-sorbitol (DBS) and its derivatives--efficient, versatile and industrially-relevant low-molecular-weight gelators with over 100 years of history and a bright future.

Dibenzylidene-D-sorbitol (DBS) has been a well-known low-molecular-weight gelator of organic solvents for over 100 years. As such, it constitutes a very early example of a supramolecular gel--a research field which has recently developed into one of intense interest. The ability of DBS to self-assemble into sample-spanning networks in numerous solvents is predicated upon its 'butterfly-like' structure, whereby the benzylidene groups constitute the 'wings' and the sorbitol backbone the 'body'--the two parts representing the molecular recognition motifs underpinning its gelation mechanism, with the nature of solvent playing a key role in controlling the precise assembly mode. This gelator has found widespread applications in areas as diverse as personal care products and polymer nucleation/clarification, and has considerable potential in applications such as dental composites, energy technology and liquid crystalline materials. Some derivatives of DBS have also been reported which offer the potential to expand the scope and range of applications of this family of gelators and endow the nansocale network with additional functionality. This review aims to explain current trends in DBS research, and provide insight into how by combining a long history of application, with modern methods of derivatisation and analysis, the future for this family of gelators is bright, with an increasing number of high-tech applications, from environmental remediation to tissue engineering, being within reach.

A avaliação da aprendizagem a distância: um estudo em representações sociais / Evaluation of distance learning: a study in social representations

Este estudo consiste em um relato de pesquisa sobre a avaliação da aprendizagem na modalidade a distância. Optou-se pelo suporte teórico-metodológico da Teoria das representações sociais explicitada por Moscovici (1978, 2003), Jodelet (2011) Abric (2001) e Sá (2002). Tem como objetivo identificar as representações sociais que os alunos de pedagogia a distância de uma universidade mineira estão construindo sobre a avaliação da aprendizagem. Os procedimentos de coleta de dados incluíram a aplicação de um questionário, com questões abertas e outras formuladas de acordo com a escala Likert; a técnica de associação livre de palavras, tratadas pelo software Evoc, que busca identificar nas representações sociais os elementos centrais e periféricos; e a realização de grupos focais. Participaram da pesquisa 212 alunos concluintes do curso de pedagogia a distância dos polos Triângulo (Araxá, Uberaba, Uberlândia); Espírito Santo (Cariacica, Colatina) e Regional Triângulo Mineiro (São Gotardo). De acordo com as análises realizadas, foi possível verificar que o projeto pedagógico do curso prevê uma avaliação processual e formativa. Os dados demonstram também que os alunos estão construindo diferentes representações sobre a avaliação a distância. Possivelmente, essas representações estão ancoradas em sentimento que denota ser a avaliação: “uma atividade de aprendizagem e conhecimento” (53%); “adequada que permite a realização de um curso a distância, porém exige dedicação e persistência” (20%); “complexa, rigorosa, tradicional, classificatória e que não mede conhecimentos” (27%).(AU)

This study consists of a research report on the evaluation of a distance learning course. We chose theoretical and methodological supports of Social Representation Theory explained by Moscovici (1978, 2003), Jodelet (2011), Abric (2001) and Sá (2002). Its objective is to identify the social representations that students of a distance learning course of University of Minas Gerais in Brazil are constructing on their evaluation of learning. The procedures for data collection included the use of a questionnaire with open questions and others formulated according to Likert scale; the technique of free association of words by Evoc software, which tries to identify social representations of central and peripheral elements, and the organization of focus groups. 212 graduating students of the pedagogy distance learning course participated in the research of the School of Education of the Minas Triangle (Araxá, Uberaba, Uberlândia), Espírito Santo (Cariacica, Colac) and Minas Triangle region (São Gotardo). According to the analysis performed, we found that the pedagogical project of the course provides a procedural and formative assessment. The data also show that students are constructing different representations of distance learning. Possibly these representations are anchored in the idea that the evaluation is “an activity of learning and knowledge” (53%), “an adequate activity for a distance course, but it requires dedication and persistence” (20%); “complex, rigorous, traditional, classificatory, but it does not measure knowledge” (27%).(AU)

Empregabilidade e competências: uma análise de universitários sob a ótica de gestores de recursos humanos / Employability and competency: the point of view of human resource managers on undergraduate students

A empregabilidade pode ser compreendida como um conjunto de competências e habilidades necessárias para uma pessoa conquistar e manter um trabalho. A pesquisa objetivou identificar as características mais importantes e as principais dificuldades percebidas para a contratação sob o ponto de vista dos gestores de recursos humanos, bem como as habilidades e competências exigidas atualmente. Participaram 156 empresas do Estado de São Paulo, que responderam a um questionário com dados de identificação e sete questões de múltipla escolha sobre empregabilidade. A coleta ocorreu de forma coletiva em um evento empresarial. Os resultados apontam que a entrevista é a fase de maior dificuldade num processo seletivo e que as maiores limitações para se encontrarem candidatos qualificados profissionalmente são a falta de experiência e a falta de preparo técnico. No âmbito pessoal, a falta de iniciativa e de motivação ou interesse se destacou, e, no âmbito acadêmico, a falta de cursos complementares e de atualização foi o ponto principal. Verificou-se que, para efetivação, as empresas procuram, em alto grau, candidatos que possuam comprometimento ou interesse e responsabilidade(AU)
