Justiça restaurativa: a construção de um novo paradigma penal e seus efeitos na vitimização secundária
O presente trabalho possui como objetivo analisar a justiça restaurativa como a possibilidade para construção de um novo paradigma penal, bem como seu conceito e objetivos, as principais diferenças e semelhanças entre o instituto da justiça convencional e justiça restaurativa. Trata-se de uma pesquisa bibliográfica em que a coleta de dados acontecerá mediante acesso a doutrinas, revistas, decretos, legislações e levantamento literário (impresso e/ou digital). O anúncio da falibilidade do sistema carcerário brasileiro, como órgão ressocializador do agente criminoso, não é novidade. Diante deste fato surge entre os criminologistas um novo ideal de justiça que visa a reintegração de vítimas e infratores à sociedade, reduz os efeitos punitivos e marginalizadores do sistema penal atual, considera questões além da punição. Constitui-se, assim, a justiça restaurativa que representa um avanço satisfatório para o direito penal moderno, restaura ofensores, vítimas e sociedade e reduz os efeitos da vitimização secundária
A proposed methodology for the correction of the Leaf Area Index measured with a ceptometer for pinus and eucalyptus forests = Proposta de uma methodologia para a correcao do indice de area foliar medido pelo ceptometro em provoamentos de pinus e eucalyptus
Leaf area index (LAI) is an important parameter controlling many biological and physiological processes associated with vegetation on the Earth's surface, such as photosynthesis, respiration, transpiration,
carbon and nutrient cycle and rainfall interception. LAI can be measured indirectly by sunfleck ceptometers in an easy and non-destructive way but this practical methodology tends to underestimated when measured
by these instruments. Trying to correct this underestimation, some previous studies heave proposed the multiplication of the observed LAI value by a constant correction factor. The assumption of this work is LAI obtained from the allometric equations are not so problematic and can be used as a reference LAI to develop a new methodology to correct the ceptometer one. This new methodology indicates that the bias (the difference between the ceptometer and the reference LAI) is estimated as a function of the basal area per unit ground area and that bias is summed to the measured value. This study has proved that while the measured Pinus LAI needs a correction, there is no need for that correction for the Eucalyptus LAI. However, even for this last specie the proposed methodology gives closer estimations to the real LAI values
Chemical and physical properties of some hazelnut varieties grown in Portugal
Hazelnuts are one of the most appreciated nuts worldwide due to their unique organoleptic
and nutritional characteristics. The present work intended to analyse several physical and chemical
properties of different hazelnut varieties grown in Portugal, namely Tonda de Giffoni, Grada de
Viseu, Segorbe, Longa de Espanha, Butler, Gunslebert, and Negreta. In general, the results revealed
statistically significant differences between the varieties under study. The Gunslebert had more
elongated hazelnuts and with heavier shelled fruits, while the kernels of the Grada de Viseu revealed
to be heavier. Grada de Viseu was harder in the shell, Gunslebert had a harder core, and Segorbe
was more resistant to fracture. Fat was the more representative component for all varieties and in
some cases the values of moisture and water activity were over the recommended amount ( 0.62).
Tonda de Giffoni was the variety with the highest induction time, indicating the highest oxidation
stability. Moreover, discriminant analysis revealed that the variables more important to distinguish
the varieties were protein ( = 0.007) and water activity ( = 0.010). The results of this study help to
better understand the differences between some hazelnut varieties that are cultivated in Portugal,
which gives important hints for all players in the hazelnut sector.This study was supported by the National Funds through the FCT-Foundation for Science and

Can introgression in M-lineage honey bees be detected by abdominal colour patterns?
Honey bee abdominal pigmentation is one of the most recognisable traits and it is often used by
beekeepers as an indicator of M-lineage subspecies purity. However, this approach may negatively impact
population diversity and is futile if there is no association between tergite colour patterns and the genetic
background. To assess whether this trait can be used as a proxy for introgression proportions in M-lineage
subspecies, we genotyped, with highly informative SNP assays, A. m. mellifera and A. m. iberiensis individuals
displaying four different colour phenotypes. The SNP data detected highly introgressed bees exhibiting a black
phenotype and, at the same time, pure or marginally introgressed bees with yellow banding patterns, in both
subspecies. Despite these observations, contrary to A. m. iberiensis , in A. m. mellifera , introgression proportions
revealed to be a significant predictor of abdominal pigmentation. Therefore, abdominal pigmentation could be used
by A. m. mellifera conservationists to guide colony selection when genetic tools are unavailable.KAB was funded by Dr. Tony Ryan research

Conservation of European M-lineage honey bees using abdominal colour as an indicator of subspecies purity has pitfalls
There are 31 honey bee (Apis mellifera) recognized subspecies, which have been grouped into four main
lineages. Two of these lineages occur naturally in Europe: M in western and northern Europe and C in southeastern Europe. In Europe, M-lineage groups only two subspecies, Apis mellifera mellifera and Apis mellifera iberiensis, both being black in colour. C-Lineage groups have instead eight subspecies, including one of the beekeepers-favored and phenotypically distinct, the yellow Apis mellifera ligustica from Italy. M-lineage
honey bees’ distribution has been changing and in some countries, the native bee is being replaced or
hybridised with C-lineage subspecies. Honey bee abdominal pigmentation is one of the most recognisable
traits and it has been used by beekeepers as an indicator of subspecies identity. However, this approach may
negatively impact population diversity and is futile if there is no association between tergite colour patterns
and genetic background. To test this approach, we calculated the introgression level of A. m. mellifera (N=162)
and A. m. iberiensis individuals (N=559) with different colour phenotypes and from a wide geographical range
using informative SNPs. In this study, many A. m. mellifera samples showed high levels of C-lineage
introgression. The individuals collected in Iberia were revealed to be pure. Introgressed A. m. iberiensis
individuals were all from the Azores, where a high frequency of C-lineage mitotypes exists in several islands.
Our results showed that for both subspecies, it is not possible to directly identify introgressed individuals from
observed colour patterns, as we found black honey bees with a considerable amount of introgression and honey bees with yellow banding that were pure or marginally introgressed. With this study, we hope to increase
awareness among stakeholders of the need to use other tools to select honey bees for conservation and breeding purposes.This work was financed by the Native Irish Honeybee Society (NIHBS), Federation of Irish Beekeeping Associations (FIBKA) and FEDER (Fundo Europeu de Desenvolvimento Regional) through the program COMPETE 2020–POCI (Programa Operacional para a Competividade e Internacionalização) and by the Portuguese funds through FCT (Fundação para a Ciência e a Tecnologia) in the framework of the project BeeHappy (POCI-01-0145-FEDER-029871).

Differential metabolic and biological profiles of Lychnophora ericoides mart. (Asteraceae) from different localities in the Brazilian "campos rupestres"
This paper reports HPLC-DAD-MS/MS and HPLC-ECD characterisation of secondary metabolite profiles of Lychnophora ericoides Mart. leaf extracts from different provenances and their cytotoxic and antioxidant properties. Leaf extracts from populations representing seven different locations were evaluated for antioxidant activity by the DPPH radical scavenging system and activity towards cellular growth in three tumor cell lines. The extracts were electrochemically analysed by HPLC-ECD and their main secondary metabolites were identified by HPLC-DAD-MS and HPLC-DAD-MS/MS. An amplified defensive secondary chemistry, together with maximal cytotoxic and antioxidant bioactivities, were found for plants collected at the interface between two types of forest. These findings furnish additional support for the hypothesis that plants occurring at the interface between two forests ecosystems might be stimulated to amplify their own production and storage of defensive secondary metabolites due to the greater number of environmental influences
Bioinformatics analysis of circulating miRNAs related to cancer following spinal cord injury
Patients with spinal cord injury (SCI) have an increased risk of developing esophageal, bladder and hematologic malignancies compared with the normal population. In the present study, we aimed to identify, through in silico analysis, miRNAs and their target genes related to the three most frequent types of cancer in individuals with SCI. In a previous study, we reported a pattern of expression of miRNAs in 17 sedentary SCI males compared with 22 healthy able-bodied males by TaqMan OpenArray. This list of miRNAs deregulated in SCI patients was uploaded to miRWALK2.0 to predict the target genes and pathways of selected miRNAs. We used Cytoscape software to construct the network displaying the miRNAs and their gene targets. Among the down-regulated miRNAs in SCI, 21, 19 and 20 miRNAs were potentially associated with hematological, bladder and esophageal cancer, respectively, and three target genes (TP53, CCND1 and KRAS) were common to all three types of cancer. The three up-regulated miRNAs were potentially targeted by 18, 15 and 10 genes associated with all three types of cancer. Our current bioinformatics analysis suggests the potential influence of several miRNAs on the development of cancer in SCI. In general, these data may provide novel information regarding potential molecular mechanisms involved in the development of cancer among individuals with SCI. Further studies aiming at understanding how miRNAs contribute to the development of the major cancers that affect patients after SCI may help elucidate the role of these molecules in the pathophysiology of the disease.39CAPES - Coordenação de Aperfeiçoamento de Pessoal e Nível SuperiorFAPESP – Fundação de Amparo à Pesquisa Do Estado De São PauloSem informação2017/23563-
Modelo de predição diagnóstica para discinesias induzidas por levodopa na doença de Parkinson
Background: There are currently no methods to predict the development of levodopa-induced dyskinesia (LID), a frequent complication of Parkinson's disease (PD) treatment. Clinical predictors and single nucleotide polymorphisms (SNP) have been associated to LID in PD. Objective: To investigate the association of clinical and genetic variables with LID and to develop a diagnostic prediction model for LID in PD. Methods: We studied 430 PD patients using levodopa. The presence of LID was defined as an MDS-UPDRS Part IV score ≥1 on item 4.1. We tested the association between specific clinical variables and seven SNPs and the development of LID, using logistic regression models. Results: Regarding clinical variables, age of PD onset, disease duration, initial motor symptom and use of dopaminergic agonists were associated to LID. Only CC genotype of ADORA2A rs2298383 SNP was associated to LID after adjustment. We developed two diagnostic prediction models with reasonable accuracy, but we suggest that the clinical prediction model be used. This prediction model has an area under the curve of 0.817 (95% confidence interval [95%CI] 0.77‒0.85) and no significant lack of fit (Hosmer-Lemeshow goodness-of-fit test p=0.61). Conclusion: Predicted probability of LID can be estimated with reasonable accuracy using a diagnostic clinical prediction model which combines age of PD onset, disease duration, initial motor symptom and use of dopaminergic agonists.Introdução: No momento, não há métodos para se predizer o desenvolvimento de discinesias induzidas por levodopa (DIL), uma frequente complicação do tratamento da doença de Parkinson (DP). Preditores clínicos e polimorfismos de nucleotídeo único (SNP) têm sido associados às DIL na DP. Objetivo: Investigar a associação entre variáveis clínicas e genéticas com as DIL e desenvolver um modelo de predição diagnóstica de DIL na DP. Métodos: Foram avaliados 430 pacientes com DP em uso de levodopa. A presença de DIL foi definida como escore ≥1 no item 4.1 da MDS-UPDRS Parte IV. Nós testamos a associação entre variáveis clínicas específicas e sete SNPs com o desenvolvimento de DIL, usando modelos de regressão logística. Resultados: Em relação às variáveis clínicas, idade de início da doença, duração da doença, sintomas motores iniciais e uso de agonistas dopaminérgicos estiveram associados às DIL. Apenas o genótipo CC do SNP rs2298383 no gene ADORA2A esteve associado com DIL após o ajuste. Nós desenvolvemos dois modelos preditivos diagnósticos com acurácia razoável, mas sugerimos o uso do modelo preditivo clínico. Esse modelo de predição tem uma área sob a curva de 0,817 (intervalo de confiança de 95% [IC95%] 0,77‒0,85) e sem perda significativa de ajuste (teste de qualidade de ajuste de Hosmer-Lemeshow p=0,61). Conclusão: A probabilidade prevista de DIL pode ser estimada, com acurácia razoável, por meio do uso de um modelo preditivo diagnóstico clínico, que combina a idade de início da doença, duração da doença, sintomas motores iniciais e uso de agonistas dopaminérgicos
