Courts under Construction in Angola: What can they do for the Poor?

This paper is about the role that may be envisioned for the courts in Angola with respect to the poor. Looking at the period from 1992 – 2004, it analyses the factors that are necessary for getting social rights litigation successfully through the courts – and what kind of impediments that exist. In spite of rather wide constitutional guarantees of a large number of social, economic and cultural rights, Angola is a highly unequal society where discrimination has been rampant in many spheres of social, political and economic life. Yet, the state has not been challenged with upholding these constitutional guarantees. This paper tries to identify some of the conditions necessary for such cases to be introduced to courts and to be effectively ruled upon by judges. What obstacles would a poor litigant, whose rights had not been respected, be faced with? Would the case be likely to be brought to court – and if it were, would it be favourably received? The paper’s tentative conclusion is that the failure to implement social and economic rights in Angola is not primarily due to constitutional limitations, but rather due to the lack of resources among the poor as well as to lack of human and technical resources within the justice system itself

Genome-wide clonal variability in European pear “Rocha” using high-throughput sequencing

Pears (Pyrus) are one of the most economically important fruits worldwide. The Pyrus genus is characterized by a high degree of genetic variability between species and interspecific hybrids, and several studies have been performed to assess this variability for both cultivated and wild accessions. These studies have mostly been limited by the resolving power of traditional molecular markers, although in the recent past the availability of reference genome sequences or SNP arrays for pear have enhanced the capability of high-resolution genomics studies. These tools can also be applied to better understand the intra-varietal (or clonal) variability in pear. Here we report the first high resolution genomics analysis of a pear clonal population using whole genome sequencing (WGS). Results showed unique signatures for the accumulation of mutations and transposable element insertions in each clone, which are likely related to their history of propagation and cultivation. The nucleotide diversity remained low in the clonal collection with the exception of few genomic windows, suggesting that balancing selection may be occurring. These windows included mainly genes related to plant fertility. Regions with higher mutational load were partially associated with transcription factors, probably reflecting the distinctive phenotypes in the collection. The annotation of variants also revealed the theoretical disruption of relevant genes in pear. Taken together, the results from this study show that pear clones accumulate mutations differently, and that those mutations can play a role on pear phenotypes, meaning that the study of pear clonal populations can be relevant in genetic studies, mainly when comparing with traditional association studies.info:eu-repo/semantics/publishedVersio

Bioinformatic tools in the study of ancient dogs: preliminary results of an Iberian case study

In this study, we attempted to carry out a genomic amplification of ancient DNA from four pre-historic Iberian dogs using the Illumina sequencing method; to assign mtDNA sequences to the major dog haplogroups and to characterize some phenotypic traits of these dogs.This study is being developed within the Woof project - PTDC/HARARQ/29545/2017, supported by national funds by FCT/MCTES and co-supported by Fundo Europeu de Desenvolvimento Regional (FEDER) throughout COMPETE - POCI – Programa Operacional Competividade e Internacionalização (POCI-01-0145 - FEDER- 029545 ), as well as by the post-doctoral grant SFRH/BPD/112653/2015 (AEPires), SFRH/BPD/108236/2015 (CDetry) and IF/00866/2014 (CGinja)info:eu-repo/semantics/publishedVersio

Chemical Profile and Biological Activities of Brassica rapa and Brassica napus Ex Situ Collection from Portugal

This study aimed to analyse the chemical profile and biological activities of 29 accessions of Brassica rapa (turnips) and 9 of Brassica napus (turnips and seeds) collections, maintained ex situ in Portugal. HPLC-HRMS allowed the determination of glucosinolates (GLS) and polyphenolic compounds. The antioxidant and antimicrobial activities were determined by using relevant assays. The chemical profiles showed that glucosamine, gluconasturtiin, and neoglucobrassin were the most abundant GLS in the extracts from the turnip accessions. Minor forms of GLS include gluconapoleiferin, glucobrassicanapin, glucoerucin, glucobrassin, and 4-hydroxyglucobrassin. Both species exhibited strong antioxidant activity, attributed to glucosinolates and phenolic compounds. The methanol extracts of Brassica rapa accessions were assessed against a panel of five Gram-negative bacteria (Enterobacter cloacae, Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica subsp. enterica serovar, and Yersinia enterocolitica) and three Gram-positive bacteria (Bacillus cereus, Listeria monocytogenes, and Staphylococcus aureus). The extracts exhibited activity against S. enterica and S. aureus, and two showed inhibitory activity against E. coli and Y. enterocolitica. This study provides valuable insights into the chemical composition and biological properties of Brassica rapa and Brassica napus collections in Portugal. The selected accessions can constitute potential sources of natural antioxidants and bioactive compounds, which can be used in breeding programs and improving human health and to promote healthy food systems.Work developed within the project was financially supported by PDR2020-7.8.4-FEADER-784- 042736 Conservação e melhoramento de Hortícolas and Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES to CIMO (UIDB/00690/2020), and Centro de Química Estrutural (CQE) is supported by the Fundação para a Ciência e Tecnologia (FCT, Portugal) through Projects UIDB/00100/2020 and UIDP/00100/2020.info:eu-repo/semantics/publishedVersio

Iberian Chalcolithic Canis: a genomic approach to know them better

To our knowledge, for Iberian ancient dogs and wolves, this is the first attempt to successfully apply NGS methods.This study is being developed within the Woof project - PTDC/HISARQ/ 29545/2017 (CIBIO-InBIO), supported by portuguese funds by FCT/MCTES and co-supported by Fundo Europeu de Desenvolvimento Regional (FEDER) throughout COMPETE - POCI – Programa Operacional Competividade e Internacionalização (POCI-01-0145-FEDER-029545), as well as by the postdoctoral grant SFRH/BPD/112653/2015 (AEPires), SFRH/BPD/108236/2015 (CDetry) and IF/00866/2014 (CGinja).info:eu-repo/semantics/publishedVersio

Publisher Copyright: © 2022 by the authors. Licensee MDPI, Basel, Switzerland.Bread wheat (Triticum aestivum) is a major crop worldwide, and it is highly susceptible to heat. In this work, grain production and composition were evaluated in Portuguese T. aestivum germplasm (landraces and commercial varieties), which was subjected to heat after anthesis (grain filling stage). Heat increased the test weight (TW) in Nabão, Grécia and Restauração, indicating an improved flour-yield potential. Mocho de Espiga Branca (MEB) and Transmontano (T94) showed higher thousand-kernel weight (TKW). Gentil Rosso presented increased soluble sugars, which are yeast substrates in the bread-making process. Ardila stood out for its protein increase under heat. Overall SDS was unaffected by higher temperature, but increased in T94, indicating a better dough elasticity for bread-making purposes. Under heat, lipid content was maintained in most genotypes, being endogenous fatty acids (FAs) key players in fresh bread quality. Lipid unsaturation, evaluated through the double bond index (DBI), also remained unaffected in most genotypes, suggesting a lower flour susceptibility to lipoperoxidation. In Grécia, heat promoted a higher abundance of monounsaturated oleic (C18:1) and polyunsaturated linoleic (C18:2) acids, which are essential fatty acids in the human diet. This work highlighted a great variability in most parameters both under control conditions or in response to heat during grain filling. Cluster analysis of traits revealed a lower susceptibility to heat during grain filling in Ardila, Restauração, and Ruivo, in contrast to MEQ, which seems to be more differentially affected at this stage. Characterization and identification of more favorable features under adverse environments may be relevant for agronomic, industrial, or breeding purposes, in view of a better crop adaptation to changing climate and an improved crop sustainability in agricultural systems more prone to heat stress.publishersversionpublishe
