A standard proposal for biological resources centres
Purpose The purpose of this paper is to contribute to develop a standard providing requirements for managing the quality and competence of the biological resource centres (BRC). Design/methodology/approach The methodology for the standard setting was based on the principles of credibility, transparency, alignment and consistency. A justification study was performed to establish its objectives and scope, avoid overlap and prevent the risks in implementation. International documents providing rules for standard development were taken into consideration. Requirements were assembled from several standards and participation of interested parties was promoted. Findings No relevant international document exists covering fundamental issues for BRC operation. It is possible to develop a consistent and aligned standard, under a credible and transparent process that fits BRC purposes. Practical implications This standard will strengthen the BRC technical competence increasing its capability to provide authenticated high-quality biological materials a crucial factor for biotechnological developments in the fields of health, agriculture and environment. It will serve as a basis for the BRC compliance assessment and the launch pad for establishing the global BRC network.The research leading to these results has received funding from the European Union’s Seventh Framework Programme (FP7/2007-2013) under Grant Agreement No. 312251 (MIRRI project)
Matrix-assisted laser desorption/ionization time-of-flight intact cell mass spectrometry to detect emerging pathogenic Candida species
Matrix-assisted laser desorption/ionization time-of-flight intact cell mass spectrometry (MALDI-TOF-ICMS) was used to differentiate pathogenic Candida species, difficult to identify by traditional methods such as growth and biochemical reactions. Results showed that species complexes like C. parapsilosis, C. orthopsilosis, and C. metapsilsosis, and very closely related species like C. glabrata and C. bracarensis, and C. albicans and C. dubliniensis could be clearly separated. MALDI-TOF-ICMS stands out as a promising tool for the rapid detection of emerging pathogens.Research leading to these results received funding from the European Community's Seventh Framework Program (FP7 2007-2013), Research Infrastructures Action, under grant agreement no.

Avaliação térmica provocada pela furação no tecido ósseo
Este trabalho tem como objetivo avaliar o efeito da temperatura no osso devido ao aquecimento provocado
pelo processo de furação. Foram realizadas visitas a duas clínicas para acompanhamento da técnica de
implantologia dentária e recolhidas imagens termográficas para a leitura da temperatura gerada na broca após o
processo de furação. Na colocação de implantes dentários por exemplo, as variáveis que interferem no processo
de furação do osso são: a velocidade, o material, o diâmetro, o comprimento e a geometria da ponta da broca.
Com este trabalho pretende-se verificar, experimental e numericamente, as variáveis que interferem no aquecimento
da estrutura óssea. Para isso, são utilizados materiais compósitos com características similares ao osso
cortical e trabecular. A metodologia apresentada revela-se útil e diferenciadora de outros trabalhos, pois são utilizados
materiais com características similares aos materiais in vivo. Os métodos experimentais utilizados em
laboratório são baseados nas técnicas de termografia e termopares durante a furação dos diferentes materiais.
Paralelamente, são utilizados modelos teóricos numéricos, com o recurso à técnica de elementos finitos, para a
discussão de resultados. Após a elaboração do trabalho conclui-se que a temperatura na broca é superior à temperatura
no osso e aumenta consoante a estrutura do material, isto é, se o material possuir cavidades na sua estrutura
a temperatura na broca não é tão elevada como no material compacto
How to deal with multiple quality management systems
International standards and best practice documents, play a crucial role in culture collections
(CC) by establishing provisions (such as recommendations, rules and specifications) for
various aspects of CC operation. Some key elements for which standards are of utmost
importance are: quality assurance, as they provide the framework for standardised processes
and protocols conducting to consistent and reliable results as well as compatibility across
culture collections; validity and traceability of results, ensuring they are accurate, reliable,
and comparable providing confidence to all interested parties; competence assurance;
designing mechanisms for ongoing monitoring, managing safety, security, and risk.
Adherence to different standards increases the CC robustness and may expand the range of
services. Also enhances market force because users/clients are loyal to organizations that
are competent and supply high-quality biological material. Different standards may be
implemented in culture collections, according to the CCs goals. The challenge of
implementing multiple standards requires strategies to provide a unified framework an
integrated management system - to address the requirements of each standard while
ensuring consistency and efficiency in operation. It requires accurate planning and
coordination. The implementation may include several stages such as conducting a gap
analysis, outlining tasks, timelines, responsibilities, and resources, providing training, building
awareness, establishing a cross-functional team, monitoring the progress towards the
objectives, and performing the review of the integrated system. Implementation of several
standards is a challenge requiring careful planning although, the resulting integrated
management system provides the culture collections with a comprehensive quality system,
contributing to the overall reliability, accuracy, and credibility of the CC operation.This research had the partial financial support of the European Union’s Horizon 2020 research and innovation programme under grant agreement nº 871129 - IS_MIRRI21 Project and of “MIRRI-PT (Polo Norte)” project (PINFRA04/84445/2020) funded by the ERDF under the scope of Norte2020 Programa Operacional Regional do Norteinfo:eu-repo/semantics/publishedVersio
Total and labile organic carbon content in agroecological system.
In an intercropping lettuce-carrot system submitted to crescent dosages of organic compost (0; 12; 24; 48 Mg ha-1) were monitored carbon from soil microbial biomass (MBC), labile carbon in fumigated soil (LCF), in non-fumigated soil (LCNF), in autoclaved soil (LCA) and total organic carbon (TOC) at 0-10 cm of depth. Pasture and forest areas surrounding the experiment were used as reference. Five samples from soil were evaluated at 8 days before the beginning of the experiment, 0; 6; 60 and 114 days after manuring (dam). LCF was the attribute that presented the most consistent correlation with TOC that is usually utilized to detect changes in soil organic matter. Increasing dosages of organic compost caused the increase of MBC, LCF, LCNF, LCA and TOC. From 60 days after planting and forward, MBC and LCF presented decrease of their levels according to the quality of organic compost. Pasture and forest soils behave as contrasts, holding lower and higher content of carbon of soil, respectively
