Atributos físicos e químicos de argissolo amarelo sob cultivo orgânico.

A utilização de sistemas orgânicos de produção agrícola tem ganhado destaque no cenário mundial principalmente devido à busca por alimentos de maior qualidade, mas também por outros benefícios como a conservação/melhoria de características físicas, químicas e biológicas do solo, aliada ao menor impacto ambiental. O presente trabalho propõe a avaliar a qualidade física e química de um Argissolo após dois anos de cultivo orgânico de videira de vinho, tendo como referência uma área de pousio. A avaliação se deu através da análise da estabilidade de agregados, dos cálculos dos índices de e de dispersão floculação do solo, da densidade do solo e do teor de carbono orgânico, a partir de amostras coletadas nas linhas e entrelinhas da videira e área de pousio, nas profundidades de 0-0,10, 0,10-0,20; 0,20-0,30 m e 0,30-0,60 m. Observou-se que o sistema influenciou a agregação do solo; o manejo nas linhas com a implantação de coquetéis vegetais possivelmente elevou o conteúdo de matéria orgânica quando comparado à entrelinha e pousio; e foram encontrados maiores teores dos elementos Mg e Ca na área de pousio e na linha de plantio, o mesmo não ocorrendo para K e Na

Exercise twice-a-day potentiates markers of mitochondrial biogenesis in men

Endurance exercise begun with reduced muscle glycogen stores seems to potentiate skeletal muscle protein abundance and gene expression. However, it is unknown whether this greater signaling responses is due to performing two exercise sessions in close proximity-as a first exercise session is necessary to reduce the muscle glycogen stores. In the present study, we manipulated the recovery duration between a first muscle glycogen-depleting exercise and a second exercise session, such that the second exercise session started with reduced muscle glycogen in both approaches but was performed either 2 or 15 hours after the first exercise session (so-called twice-a-day and once-daily approaches, respectively). We found that exercise twice-a-day increased the nuclear abundance of transcription factor EB (TFEB) and nuclear factor of activated T cells (NFAT) and potentiated the transcription of peroxisome proliferator-activated receptor-ɣ coactivator 1-alpha (PGC-1α), peroxisome proliferator-activated receptor-alpha (PPARα), and peroxisome proliferator-activated receptor beta/delta (PPARβ/δ) genes, in comparison with the once-daily exercise. These results suggest that part of the elevated molecular signaling reported with previous train-low approaches might be attributed to performing two exercise sessions in close proximity. The twice-a-day approach might be an effective strategy to induce adaptations related to mitochondrial biogenesis and fat oxidation

Mapeamento pedológico em relevos cársticos a partir da análise morfométrica.

ABSTRACT - The space has elements of physical, biotic and anthropic order that interact and impel other elements of an inferior hierarchy in a successive way which propitiate the formation of emerging properties that feed a system of higher subsequence, configuring what we visually know as landscape. This system possesses its own characteristics in accordance with each area of influence of more predominant elements, where it is possible the determination of patterns and models within a space and temporary scale. This work proposes the modeling of a landscape from geomorphologic variables (an element under geologic and hydrologic influences mainly), based on a digital model of the terrain in a region where the natural process and the anthropic one on the carbonatic rocks are expressive. Due to the drainage shape, the corrosive action on the rocks makes up the main characteristic of the carstic landscape instead of performing the erosive process. The proposed statistical method establishes relationships between morphometric parameters and pedological units

Physical activity for people with dementia: A scoping study

Background: This scoping study aimed to identify how physical activity may benefit people with dementia; how and/or if current service provide these benefits; and what support they need to do so. Methods: Methods included an evidence review using literature; mapping current service provision through a survey; and in-depth interviews with a sample of service providers. Results: The 26 studies included in the review indicated the potential effectiveness of physical activity for people with dementia, including improvements in cognition and mood, behaviour and physical condition. Mechanisms of action and the link with outcomes were poorly defined and implemented. The mapping survey and related interviews showed that service providers were delivering a range of services broadly consistent with the scientific evidence. They tended to take a holistic view of possible benefits, and focused on enjoyment and well-being, more than specific cognitive, physical and behavioural outcomes highlighted in literature. Service providers needed more evidence based information and resources to develop services and realise their potential. Conclusion: Despite potential benefits demonstrated in literature and practice, there is a need for further research to optimise interventions and to consider some neglected issues including delivery at home and in communities; impacts for carers; physical activities through ADLs; and individual needs. Studies are needed which take a more holistic approach to the effects of physical activity, and outcomes should be broader and include mental health and wellbeing

Impact of physical activity on activity of daily living in moderate to severe dementia: a critical review

The objectives of this study were to describe the different modalities of physical activity programs designed for moderate to severe dementia and to identify their impact on functional independence in activities of daily living (ADL). A critical review of randomized controlled trials related to the impact of physical activity programs in moderately to severely demented persons on ADL performance and meta-analysis of the identified studies were performed. Among the 303 identified articles, five responded to the selection criteria. Four out of the five studies demonstrated limited methodological quality. In one high-quality study, physical activity programs significantly delayed deterioration of ADL performance. The program components and ADL assessment tools vary widely across studies. Although the proposed treatments have not proven their efficiency in improving the ADL status of the patients, they were able to limit the decline in ADL functioning. Future research is warranted in order to identify clinically relevant modalities for physical activity programs for people with moderate to severe dementia
