Microdiversity of Burkholderiales associated with mycorrhizal and nonmycorrhizal roots of Medicago truncatula

2008

The genetic diversity of bacterial communities associated with mycorrhizal and nonmycorrhizal roots of Medicago truncatula was characterized by two approaches. Firstly, phylogenetic analysis was performed on 164 partial 16S rRNA gene-intergenic spacer (IGS) sequences from operational taxonomic units previously shown to be preferentially associated with mycorrhizal roots. These sequences were distributed into three branches corresponding to Comamonadaceae, Oxalobacteraceae and Rubrivivax subgroups. Most sequences were obtained from mycorrhizal roots, indicating the preferential association of the corresponding families with mycorrhizal roots. A second phylogenetic analysis was performed on t…

Summary Objectives Neisseria meningitidis is the major cause of seasonal meningitis epidemics in the African meningitis belt. In the changing context of a reduction in incidence of serogroup A and an increase in incidence of serogroups W and C and of Streptococcus pneumoniae , a better understanding of the determinants driving the disease transmission dynamics remains crucial to improving bacterial meningitis control. Methods The literature was searched to provide a multi-disciplinary overview of the determinants of meningitis transmission dynamics in the African meningitis belt. Results Seasonal hyperendemicity is likely predominantly caused by increased invasion rates, sporadic localized …

Revisiting agricultural modernisation: Interconnected farming practices driving rural development at the farm level

2019

Abstract Rural development related to agriculture can roughly be divided into two trajectories: 1) agri-industrial development or modernisation, and 2) multifunctional or even post-productivist rural development. The role of these trajectories varies in different rural settings, with different emphases on agricultural production and its conduct. At the farm level, the trajectories evolve from existing farming practices and their connections, which enable or disable different kinds of development. However, the connections through which changes in agricultural production practices contribute to different rural development trajectories deserve further scrutiny. This is addressed with the help …

Multimodal interactions

2016

Revue; International audience; Introduction A central sensory characteristic of food is its flavor, which, most of the time, confers to a given food product its identity and typicality, and thus contribute to its liking (Prescott, 2015). Flavor has been defined as a sensory percept induced by food or beverage tasting. This holistic perception is constructed through the functional integration of information transmitted by the chemical senses: olfaction, gustation, and oral and nasal somatosensory inputs (Thomas-Danguin, 2009). Flavor may be influenced by other nonchemical sensory inputs such as texture, sound, or color (Spence, 2013). The functional integration of information transmitted by …

An Avenue to Social Equilibrium

2021

The purpose of the second part of the third part of the book is to show how the theory translates into reality. That is why the most important factors studied in the first and second parts of the book are concluded in this chapter. The first part of the chapter is addressed to examine the personal characteristics and motivation of the social entrepreneur, that is, it is focused on the micro approach. The second part is addressed to analyze the institutional context, that is, it comprehends the macro approach. Based on this, the chapter shows the stages followed by social entrepreneurs to shift the context. The legitimation process is the base of this shift.

Materiales didácticos digitales y coronavirus en tiempos de confinamiento en el contexto español

2020

In this paper, a description and analysis of the main proposals of didactic materials that have been elaborated on COVID-19 (coronavirus) directed to a child and youth public available on the network in the Spanish context was made. In the first part of the paper we reflect on the reasons and needs that have justified the appearance and development of these resources. Subsequently, we present the search process carried out mainly through the Google search engine and the final selection of the materials considered. Next, a descriptive analysis of the materials was carried out using an elaborated ad hoc matrix that integrates 5 dimensions. As a general conclusion, we highlight the diversity o…

Estado de salud en adolescentes de España, México y Chile durante la COVID-19: un estudio transcultural.

2021

espanolLa pandemia provocada por la COVID-19 es una crisis sin precedentes en la historia reciente, cuyas consecuencias han tenido un impacto mundial. Una de las etapas mas vulnerables a los efectos de esta emergencia sanitaria es la adolescencia, pues atraviesan un proceso vital de cambios en diversos aspectos de su vida, y la inestabilidad social y economica se suma como factor de riesgo a su ajuste psicosocial. Los estudios a nivel transcultural han tratado de comparar y comprender las diferencias en la adaptacion de los y las adolescentes a la pandemia en diferentes partes del mundo. El objetivo de este estudio fue analizar el estado de salud actual, en comparacion con el estado de salu…

Preoperative Considerations in Order to Resume Elective Surgery During COVID-19 Pandemic

2020

Abstract The alarming spread of the novel Coronavirus necessitated the cessation of elective therapeutic procedures in most health-care facilities. This strategy has limited the spread of the virus, but with a huge socio-economic impact. For this reason, the resumption of elective surgery in the context of the coronavirus pandemic is a difficult, but necessary process. Addressing this delicate situation requires interdisciplinary collaboration, so as to ensure high quality medical care for all patients, with consideration to protection of the staff involved in the care of the surgical patient.

O-195 The impact of the COVID-19 outbreak on psychological distress due to the cancellation of ART. A systematic review and meta-analysis

2021

Abstract Study question Is there evidence that infertile patients have been more likely to experience distress during the COVID-19 outbreak with the consequent interruption of treatment plans? Summary answer High levels of psychological distress among infertile patients have been found during the COVID-19 pandemic, greater than that reported in the general population. What is known already Preliminary research on the negative consequences of the COVID-19 outbreak on mental health evidenced heightened levels of anxiety, depression and post-traumatic stress in some clinical populations as well as in community samples. However, little is known about the impact of COVID-19 on psychological dist…

Advances in plant materials, food by-products, and algae conversion into biofuels: use of environmentally friendly technologies

2019

Green technologies have emerged as useful tools for the generation of clean fuels with the potential to minimize the effect of human activity on the environment. Currently, these fuels are mainly composed of hydrocarbons obtained from crude oil. Over the past two decades, biomass has gained significant attention as a renewable feedstock for more sustainable biofuel production and has been a great candidate to replace fossil fuels. The principal components of most of the available biomass are cellulose, hemi-cellulose, and lignin. Although the available green technologies for biofuel production are progressing rapidly, productivity and chemical yield from these techniques are still below the…
