Conformational Isomerism in Drug Action: Does the Free Energy of Binding Induce the Pharmacophoric Conformation of Semi-Rigid Muscarinic Agonists?
1974
The physiological neurotransmitter Acetylcholine has been shown to have great molecular flexibility, and because of this, the possibility of forming numerous energetically different conformations. This property makes the determination of the biologically active conformation extremely complicated. In attempts to solve this problem various research groups have tried two basically different approaches: (1) (1) The determination of the energetically most stable conformation using crystallographic methods (X-ray diffraction studies), nuclear magnetic resonance and quantum-mechanical calculations [1–16]. Same workers hypothesized that the energetically most favourable form was also the biological…
La colaboración científica en el campo de las ciencias de la actividad física y el deporte en España
2010
Este estudio examina la colaboración científica a través de los patrones de coautoría en una muestra de revistas españolas de Ciencias de la Actividad Física y el Deporte (CCAFD). También analiza los principales grupos de investigación y disciplinas del campo multidisciplinar de las CCAFD. Se analizaron la frecuencia y porcentaje de los artículos en colaboración y el número de autores por artículo. Se revisaron las redes de colaboración de los autores más productivos para identificar grupos de investigación y se calculó la densidad para conocer su cohesión. La producción científica fue analizada también por disciplinas. Los artículos en colaboración superan a los artículos de autor único en…
Ethical challenges in care for older patients who resist help
2014
Background: Situations where patients resist necessary help can be professionally and ethically challenging for health professionals, and the risk of paternalism, abuse and coercion are present. Research question: The purpose of this study was to examine ethical challenges in situations where the patient resists healthcare. Research design: The method used was clinical application research. Academic staff and clinical co-researchers collaborated in a hermeneutical process to shed light on situations and create a basis for new action. Participants and research context: Four research groups were established. Each group consisted of six to eight clinical co-researchers, all employees with diff…
The ALHAMBRA survey: tight dependence of the optical mass-to-light ratio on galaxy colour up to z = 1.5
2018
[Aims] Our goal is to characterise the dependence of the optical mass-to-light ratio on galaxy colour up to z = 1.5, expanding the redshift range explored in previous work. [Methods] From the redshifts, stellar masses, and rest-frame luminosities of the ALHAMBRA multi-filter survey, we derive the mass-to-light ratio versus colour relation for quiescent and for star-forming galaxies. The intrinsic relation and its physical dispersion are derived with a Bayesian inference model. [Results] The rest-frame i-band mass-to-light ratio of quiescent and star-forming galaxies presents a tight correlation with the rest-frame (g - i) colour up to z = 1.5. The mass-to-light ratio versus colour relation …

Scientific literature analysis of Judo in Web of Science®
2013
Background & Study Aim: Although judo is a sport with great tradition that is practised worldwide, the state of the art and scientific advances have not been analysed from a bibliometric point of view up to now. The aim of the present article is the status of the scientific production, collaboration, and impact of scientific papers on judo, as well as the most active research groups working on this topic. Material & Methods: Our analysis was based on documents retrieved from the Science Citation Index and Social Science Citation Index. Bibliometric analysis and network construction were performed using Histcite and Bibexcel software. Results: As a result, 383 original papers and scientific …
Oilseed treatment by ultrasounds and microwaves to improve oil yield and quality: An overview.
2016
International audience; Efficiency is a key point to ensure the profitability in the production of vegetable oils from oilseeds. To maximize the recovery yields of seed oils, the traditional process involves mechanical expression followed by subsequent chemical extraction using organic solvents (e.g. hexane). Besides health, environmental, and economic related issues to the use of organic solvents, thermal treatment of seeds during conventional oil extraction process inevitably leads to chemical changes (e.g. changes in macronutrients such as protein denaturation/degradation in the meal, oil oxidation, and changes in minor constituents such as fatty acids, sterols, phenolic compounds and to…
A Study of the Bibliometry and Areas of the Research Groups of Archivos de Bronconeumología (2003–2007)
2010
Introduction Scientific cooperation is essential for the advance of biomedical research. Scientists set up informal groups to work together on common issues, who are the main units in the research funding system. Bibliometric and Social Network Analysis methods allow informal groups in scientific papers to be identified and characterised. The objective of the study is to identify research groups in Archivos de Bronconeumologia between 2003 and 2007 period with the aim of characterizing their scientific collaboration patterns and research areas.
The role of heat shock proteins in neoplastic processes and the research on their importance in the diagnosis and treatment of cancer
2021
Heat shock proteins (HSPs) are chaperones with highly conservative primary structure, necessary in the processes of protein folding to the most energetically advantageous conformation and maintaining their stability. HSPs perform a number of important functions in various cellular processes and are capable of modulating pathophysiological conditions at the cellular and systemic levels. An example is the high level of HSP expression in neoplastic tissues, which disrupts the apoptosis of transformed cells and promotes the processes of proliferation, invasion, and metastasis. In addition, an increasing amount of information is appearing about the participation of HSPs in the formation of multi…
ART Azzurra Robot Team
1999
Azzurra Robot Team is the result of a joint effort of seven Italian research groups from Univ. of Brescia, Univ. of Genoa, Politecnico of Milano, Univ. of Padua, Univ. of Palermo, Univ. of Parma, Univ. of Roma "La Sapienza", and the Consorzio Padova Ricerche which has provided resources and a set up of the soccer field in its Center in Padua. Our goal at Robocup 1998 has been to provide a exible and low-cost experimental team to make experience before undertaking a larger project. Our long term goal is to foster the development of research and education projects on autonomous mobile robots by exploiting the RoboCup challenge.
