الوصف: Abstract Pinus Pinaster Ait. is a softwood species indigenous of the South West of Europe, broadly spread alongside the Mediterranean Sea and present worldwide. Pinus Pinaster Ait. (ssp. Atlantica) is largely used in industrial applications including construction and buildings in the Southwest of France as it has widely grown across the whole area. However, very often, Pinus Pinaster Ait.-based product design strategies make use of properties of generic softwood species due to the lack of a proper database (or review) on the topic. This review article aims to exhaustively present the consistent scientific literature on Pinus Pinaster Ait. properties focusing on its physical, hygrical, thermal and mechanical properties. Indeed, a vast literature exists, laid out across a wide range of years and countries.

الوصف: A presente dissertação encontra-se inserida na unidade curricular Estágio Curricular do Mestrado Integrado de Ciências Farmacêuticas. Este trabalho encontra-se divido em três partes: a primeira referente ao trabalho de pesquisa bibliográfica, uma revisão da literatura sobre o potencial da espécie Pinus pinaster para aplicação na saúde; a segunda parte diz respeito ao relatório de estágio curricular realizado na farmácia comunitária; e a terceira parte descreve o estágio curricular realizado na farmácia hospitalar. O primeiro capítulo aborda a espécie Pinus pinaster, com grande distribuição em Portugal, sendo a espécie mais representativa do género Pinus, ocupando 22% da área florestada no nosso país. Foi no século XVI o primeiro caso relatado do uso desta espécie para fins medicinais. Atualmente, são vários os estudos onde são evidenciadas as propriedades que lhe são atribuídas, apresentando inúmeras atividades já relatadas a nível antioxidante, antidiabético, hepatoprotetor, antimelanogénico, antitumoral e antimicrobiano. Os autores são unânimes em considerar que tais propriedades se devem aos componentes químicos nela contidos, nomeadamente os compostos fenólicos (flavonóides, ácidos fenólicos, estilbenos, taninos e lignanas) e os terpenos, ambos metabolitos secundários, encontrados nas diferentes partes do pinheiro, com principal destaque para a casca. O segundo capítulo diz respeito ao estágio curricular realizado na farmácia São Cosme, na Covilhã. Aqui, é descrito todo o funcionamento da farmácia comunitária, assim como as tarefas realizadas no decorrer do estágio. O terceiro capítulo aborda o estágio curricular desenvolvido na farmácia hospitalar da Unidade Local de Saúde da Guarda (ULSG). Aqui estão apresentadas todas as áreas de atuação do farmacêutico hospitalar, bem como as suas funções, as quais, foi possível acompanhar.
الوصف (مترجم): The present dissertation is included in the curricular unit named Internship of Integrated Master of Pharmaceutical Sciences. This work is divided into three parts: the first relates to the bibliographic research work, a review of the literature on the potential of the species Pinus pinaster for application in health; the second part concerns the curricular internship report carried out in the community pharmacy; and the third part describes curriculum internships conducted in the hospital pharmacy. This first chapter deals with the species Pinus pinaster, with great distribution in Portugal, being the most representative species of the genus Pinus, occupying 22% of the forested area in our country. It was in the 16th century the first case of the use of this species for medicinal purposes. Currently, there are several studies where the properties that are attributed to it are evidenced, presenting numerous activities, namely antioxidant, antidiabetic, hepatoprotective, anti-melanogenic, antitumoral and antimicrobial. Authors are unanimous in considering that such properties are due to the chemical components contained in it, such as the phenolic compounds (flavonoids, phenolic acids, stilbenes, tannins and lignans) and terpenes, both secondary metabolites, found in the different parts of the pine, with main emphasis on the bark. The second chapter concerns the curricular internship conducted at the pharmacy São Cosme, in Covilhã. A description of the whole functioning of the community pharmacy is made, as well as the tasks that performed during the internship. The third chapter deals with the curricular internship developed in the hospital pharmacy at ULSG. All the areas of operation of the hospital pharmacist are presented, as well as its functions, which was possible to follow.

الوصف: Asian sand dust (ASD), also called China dust or yellow dust, mainly occurs in East Asia during spring and autumn. Because ASD enters the body mainly through the respiratory system, it can cause respiratory disorders or worsen underlying diseases. Because of this, it has become an important health concern that threatens the well-being of humans and animals. In this study, we investigated the effects of 15 and 30 mg/kg of Pycnogenol (PYC15 and 30 groups), a pine bark extract, on ASD-induced pulmonary inflammation in mice. We evaluated the inflammatory cell counts, inflammatory cytokines, and matrix-metalloproteinase (MMP)-9 expression in animal models. PYC administration significantly decreased inflammatory cell infiltration into lung tissue; this was accompanied by a reduction in the levels of proinflammatory mediators including interleukin (IL)-1β (P

الوصف: Stand density management diagrams (SDMDs) are robust decision-support tools available to forest managers under limited information. SDMDs which are based on empirical models at stand level, graphically represent the temporal relationships among stand density, and different stand variables such as quadratic mean diameter, dominant height, and mean tree volume. They are used to define initial planting spacing or thinning interventions, to meet various management objectives. Nowadays, there is a growing interest in mixed-species forests as an option for adaptive forest management, where they are considered a guarantor to safeguarding a wide variety of ecosystem services within the framework of sustainability. But there is still a lack of knowledge and efficient tools and models for mixed stands such as SDMDs. This study aims to develop an SDMD for Pinus sylvestris L. and Pinus pinaster Ait. mixed stands in the Sierra de la Demanda (Spain) using data from the third Spanish National Forest Inventory. Both species are two of the most important conifers in Europe and the western Mediterranean basin. Different variables can be used to develop an SDMD. In this case, quadratic mean diameter, dominant height, total stand volume, number of trees per hectare, and stand density index were used. These equations were fit by simultaneous fitting including a new variable representing the proportion of both species in the mixed stand. The results of the simultaneous fitting showed the new variable representing the proportion of both species was not significant. Based on that, the SDMD was constructed without including mixture degree. This SDMD can be used by forest managers as an efficient tool to plan thinning operations.

الوصف: Land use and land use change can positively or negatively affect carbon and nutrient stocks in ecosystems. This study was carried out to determine the effects of afforestation with black pine and maritime pine species on carbon stocks and soil and litter characteristics. The study was conducted on afforestation areas and adjacent bare lands in Bartın-Ulus county, located in the Western Black Sea Region of Turkey. Three sample plots of 20×20 m were taken from each land use and the diameter at breast height and tree heights in these sample plots were measured Using the diameter and height values and the biomass equations and carbon ratios developed for the relevant tree species, the tree biomass and carbon stock per unit area were calculated. Then, disturbed and undisturbed soil samples and litter samples were taken from 0-10, 10-20 and 20-30 cm depth intervals at three points in each sample plot. The physical and chemical properties of the soil and litter samples were determined in the laboratory and measurements in the sample plots were converted to a unit area. The data were evaluated using independent sample t-tests and analysis of variance. The results showed that afforestation significantly changed N, S, P, Fe, Zn, and Cu concentrations in the soil; and C, S, Mn, and Zn concentrations in black pine and maritime pine forest floor were different. Besides, the ecosystem carbon (C) stocks differed significantly with forest land use type; black pine plantations, maritime pine plantations and bare land accumulated 148 t C ha-1, 89 t C ha-1 and 27 t C ha-1, respectively. Thus, we suggest that priority should be given to black pine in afforestation of the region and in other ecosystems with similar climates. The results of the research can be used in species selection for afforestation studies in terms of reducing the impact of global climate change.

مصطلحات موضوعية: Pinus pinaster, grafting, transcriptomic analysis, drought tolerance, genotype selection, stem, Botany, QK1-989
الوصف: Climate change-induced hazards, such as drought, threaten forest resilience, particularly in vulnerable regions such as the Mediterranean Basin. Maritime pine (Pinus pinaster Aiton), a model species in Western Europe, plays a crucial role in the Mediterranean forest due to its genetic diversity and ecological plasticity. This study characterizes transcriptional profiles of scion and rootstock stems of four P. pinaster graft combinations grown under well-watered conditions. Our grafting scheme combined drought-sensitive and drought-tolerant genotypes for scions (GAL1056: drought-sensitive scion; and Oria6: drought-tolerant scion) and rootstocks (R1S: drought-sensitive rootstock; and R18T: drought-tolerant rootstock). Transcriptomic analysis revealed expression patterns shaped by genotype provenance and graft combination. The accumulation of differentially expressed genes (DEGs) encoding proteins, involved in defense mechanisms and pathogen recognition, was higher in drought-sensitive scion stems and also increased when grafted onto drought-sensitive rootstocks. DEGs involved in drought tolerance mechanisms were identified in drought-tolerant genotypes as well as in drought-sensitive scions grafted onto drought-tolerant rootstocks, suggesting their establishment prior to drought. These mechanisms were associated with ABA metabolism and signaling. They were also involved in the activation of the ROS-scavenging pathways, which included the regulation of flavonoid and terpenoid metabolisms. Our results reveal DEGs potentially associated with the conifer response to drought and point out differences in drought tolerance strategies. These findings suggest genetic trade-offs between pine growth and defense, which could be relevant in selecting more drought-tolerant Pinus pinaster trees.

مصطلحات موضوعية: Climate change, Dendrometer band, Intra-annual radial increment, Logistic model, Pinus pinaster Aiton, Pinus sylvestris L
الوصف: 16 Pág. ; Forest dynamics are undergoing profound alteration due to the fact that climate change is increasing the frequency and severity of abiotic and biotic forest disturbances. Because of the unpredictable nature of the drought periods and the variation in their severity, Mediterranean forests are typically more vulnerable. Mediterranean Pinus pinaster forests are showing decay symptoms linked to climate change. There is clear evidence that promoting mixtures can serve as an effective forest adaptation strategy. In this regard, we sought to better understand the responses of P. pinaster radial growth dynamics to various factors, in both mixed and pure forest stands, and provide valuable insights into P. pinaster dynamics when mixed with P. sylvestris. In this study, we examined the variation of intra-annual cumulative radial increment patterns in response to the climate of P. pinaster between pure and mixed stands with P. sylvestris. Using data from band dendrometers collected over five consecutive climatically distinct years (2016–2020), a nonlinear mixed-effect model approach was used to analyze the differences in intra-annual cumulative radial increment patterns for P. pinaster between years in mixed and pure stands. The intra-annual radial increment pattern of P. pinaster showed significant year-to-year variation and varied with tree size, with greater increment in larger trees. Trees in mixed stands had a higher mean radial increment compared to corresponding ones in pure stands. Increased summer maximum temperatures negatively affected tree cumulative annual increment regardless of composition, but with a lower impact on trees in pure stands. Spring precipitation increased the length of the growing season, while higher spring maximum temperatures triggered an earlier inflection point. Our results highlight the high plasticity of P. pinaster in adapting to varying intra- and inter-annual environmental conditions and competition with other species and suggest that promoting mixtures with P. sylvestris ...

الوصف: 12 páginas, 6 figuras ; Pine resin is a valuable non-wood forest product with an increasing interest in multiple industrial sectors. Resin-tapping activities also provide valuable ecosystem services in timber-oriented and highly productive pine forest of Atlantic regions, where little previous experience in resin-tapping is available. The objectives of this study were to determine the efficiency of different stimulant pastes and its variation with pine species, site conditions, seasonality and frequency of tapping interventions. We conducted parallel experiments using both conventional and micro-tapping techniques in mature pine stands in NW Spain. We tested four stimulants (control and Zeta, Cunningham and Salicylic pastes) and two groove frequencies (every 2 or 3 weeks). All stimulant pastes significantly increased resin yield compared to the control, being resin stimulation highly consistent across years, sites and species. In conventional resin tapping, resin yield was maximized with the Cunningham and Salicylic pastes while in micro-tapping Salicylic was the most outstanding stimulant treatment. According to the rapid decay of resin flow after wounding, total resin yield decreased with more spaced grooves. However, the reduction was low, and the global efficiency of the tapping operations are likely maximized with grooves applied every three weeks, which would allow increasing the number of tapped trees. Micro-tapping techniques were valuable for screening stimulant pastes and anticipating variation among sites in resin production. Altogether, the Salicylic paste is recommended, especially at the beginning of the resin campaign, when the effect of the pastes was maximized, and if tapping is conducted using closed atmospheres and containers. ; This study was supported by the Cooperation Action AC2020-08, founded by the AGACAL, Xunta de Galicia/FEADER, the ACREMA project, founded by the Spanish Government (MAPA/AEI-Agri/FEADER, UE; Grant O00000226e2000043659), and the TAPPINESS project (grant ...

مصطلحات موضوعية: Análisis nutricional de acículas, Análisis nutricional de ramas, Análisis nutricional de rodajas, Análisis químico de suelo, Incremento anual en volumen, Pinus pinaster
الوصف: Se estudiaron las propiedades del suelo y el estado nutricional en seis masas de Pinus pinaster localizadas en la parte centro - occidental de Asturias. Además, se relacionó el estatus nutricional de los suelos y de los árboles con el incremento anual medio en volumen con corteza (IAVC). Los árboles se clasificaron en 10 clases diamétricas de 5 cm de amplitud; de cada una se derribaron y midieron tres individuos dominantes y a continuación se calculó el IAVC. El análisis nutricional se realizó en acículas, ramas de diámetro comprendido entre 2 y 7 cm, de 0.5 a 2 cm, inferior a 0.5 cm y en rodajas extraídas a diferentes alturas del fuste. Las mayores concentraciones de nutrimentos se obtuvieron en las acículas, con deficiencias en el contenido de P, K y una descompensación en la relación N:P, que disminuyó progresivamente en las ramas de menor a mayor diámetro. El IAVC presentó una correlación negativa con el N, contenido de materia orgánica y Ca intercambiable en el suelo y con el Ca foliar. El P, K y Mg en las ramas de menos de 0.5 cm de diámetro tuvo una correlación positiva con el IAVC, al igual que la capacidad de intercambio catiónico efectiva, el contenido de arcilla y el pH. Los resultados indican que otros factores, como el pH del suelo, interfieren en la asimilación del Ca y revelan la importancia de reincorporar al terreno las ramas finas y ramillas, así como incorporar la fertilización en los programas de reforestación.

مصطلحات موضوعية: antimicrobial activity, antioxidant activity, biomass, Box–Behnken experimental design, deep eutectic solvents, green solvents, Pinus pinaster
الوصف: Deep eutectic solvents represent an important alternative in the field of green solvents due to their low volatility, non-toxicity, and low synthesis cost. In the present investigation, we propose the production of enriched polyphenolic extracts from maritime pine forest residues via an ultrasound-assisted approach. A Box–Behnken experimental design with a response surface methodology was used with six variables to be optimized: solid-to-solvent ratio, water percentage, temperature and time of extraction, amplitude, and catalyst concentration. The mixture of levulinic and formic acids achieved the highest extraction yield of polyphenols from pine needle and bark biomass. In addition, the solid-to-solvent ratio was found to be the only influential variable in the extraction (p-value: 0.0000). The optimal conditions were established as: 0.1 g of sample in 10 mL of LA:FA (70:30%, v/v) with 0% water and 0 M H2SO4 heated to 30 °C and extracted during 40 min with an ultrasound amplitude of 80% at 37 kHz. The bioactive properties of polyphenol-enriched extracts have been proven with significant antioxidant (45.90 ± 2.10 and 66.96 ± 2.75 mg Trolox equivalents/g dw) and antimicrobial activities. The possibility to recycle and reuse the solvent was also demonstrated; levulinic acid was successfully recovered from the extracts and reused in novel extractions on pine residues. This research shows an important alternative to obtaining polyphenol-enriched extracts from forest residues that are commonly discarded without any clear application, thus opening an important window toward the valorization of such residues. ; 16 páginas
