Single-molecule derivation of salt dependent base-pair free energies in DNA
(National Academy of Sciences, 2010)
Accurate knowledge of the thermodynamic properties of nucleic acids is crucial to predicting their structure and stability. To date most measurements of base-pair free energies in DNA are obtained in ...
Improving signal/noise resolution in single-molecule experiments using molecular constructs with short handles
(Elsevier, 2011)
We investigate unfolding/folding force kinetics in DNA hairpins exhibiting two and three states with newly designed short dsDNA handles (29 bp) using optical tweezers. We show how the higher stiffness ...
Investigating the thermodynamics of small biosystems with optical tweezers
(Elsevier, 2010)
We present two examples of how single-molecule experimental techniques applied to biological systems can give insight into problems within the scope of equilibrium and nonequilibrium mesoscopic ...
Single-molecule stochastic resonance
(American Physical Society, 2012)
Stochastic resonance (SR) is a well-known phenomenon in dynamical systems. It consists of the amplification and optimization of the response of a system assisted by stochastic (random or probabilistic) ...
Supernumerary fourth molar and dental pathologies in a Chalcolithic individual from the El Mirador Cave site (Sierra de Atapuerca, Burgos, Spain)
(Elsevier, 2015)
We present a middle-aged Chalcolithic male with a supernumerary distomolar in the mandible. The prevalence of supernumerary teeth in present-day populations is low, ranging from 0.1% to 3.4%; most ...
Root canal morphology of Chalcolithic and early bronze age human populations of El Mirador Cave (Sierra de Atapuerca, Spain)
(Wiley, 2014)
This study provides a morphological characterization of the inner anatomy of the root canals of permanent first and second molars in Chalcolithic and early Bronze Age human fossils using cone-beam ...
Study of dental occlusion in ancient human remains: a methodological approach
(Croatian Anthropological Society, 2014)
The anthropological dental and maxillary study in human skeletal remains usually refers to alterations or conditions of the oral cavity. These alterations could have repercussions on life style, dietary ...
Validation of the new graded prognostic assessment scale for brain metastases: a multicenter prospective study
(Springer Nature, 2011)
Background: Prognostic indexes are useful to guide tailored treatment strategies for cancer patients with brain metastasis (BM). We evaluated the new Graded Prognostic Assessment (GPA) scale in a ...
From metropolitan rivers to civic corridors: assessing the evolution of the suburban landscape
(Taylor & Francis, 2019)
The sustainability of metropolitan regions is closely related to the transformation of rivers into civic and ecological corridors. While river rehabilitation in the inner city has been widely reported, ...
Perception assessment of environmental factors related to leisure-time physical activity in an urban stream corridor
(Taylor & Francis, 2020)
Leisure-Time Physical Activity (LTPA) in green environments is influenced by various social and physical environmental factors. A better understanding of how green environment users perceive these factors ...
