Extraction and Sample Preparation

2015

As everyone knows, the role played by extraction and sample preparation in the analytical sciences cannot be overemphasized. Despite tremendous advances in chromatography, detection, and other aspects of analysis, extraction and sample preparation remain a preanalysis ritual of critical importance. It has been estimated that around 50% to 70% possibly even more of the time and effort that goes into an analytical process comprises extraction and sample preparation. Sample preparation procedure can vary in the degree of selectivity, speed, and convenience, depending on the approach and conditions used, as well as on the geometric configurations of the extraction phase and conditions. Proper d…

Tips on ligand immobilization and kinetic study using surface plasmon resonance.

2016

Surface plasmon resonance (SPR) technique offers a robust label-free approach applicable in various investigations including binding affinity, specificity and kinetics of biological macromolecules (e.g., peptides, proteins and nucleotidase) and small molecules. SPR provides extremely important data on the kinetics and affinity of substances examined, through which bio-specific interaction(s) can be established by the analysis of adsorption of analyte onto the immobilized ligand(s) on a sensor-based analytical system. Due to SPR wide applications in biomedical laboratories, the aim of this editorial is to highlight the importance of SPR in affinity kinetics and ligand immobilization.

Lessons from uncertainty on antifungal treatment in ICU

2017

We read with great interest the Editorial from Moghnieh et al. on the EMPIRICUS trial and antifungal use in intensive care unit (ICU) (1). Authors described nicely the trial and some background evidence on untargeted antifungal treatment in non-neutropenic critically ill patients in ICU (2,3). However, we believe that some points may be further clarified. First, it may be useful to cite the study from Knitsch et al. among those evaluating empiric antifungal treatment in ICU (4). Knitsch et al. enrolled 252 critically ill patients with localized/generalized intra-abdominal infection either of community or of nosocomial origin requiring emergency surgery.

Methodological advances in brain connectivity

2012

Determining how distinct neurons or brain regions are connected and communicate with each other is a crucial point in neuroscience, as it allows to investigate how the functional integration of specialized neural populations enables the emergence of coherent cognitive and behavioral states. The general concept of brain connectivity encompasses different aspects: structural connectivity is related to the description of anatomical pathways and synaptic connections; functional connectivity investigates statistical dependencies between spatially separated brain regions; effective connectivity refers to models aimed at elucidating driver-response relationships. The study of these different modes…

Prevalence and Time Trends in Myopia Among Children and Adolescents.

2020

Background Myopia (near-sightedness) is increasing worldwide, especially in Asia. The aim of this study was to describe trends in the prevalence of myopia in Germany. Methods We analyzed data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS; baseline survey 2003-2006, N = 17 640; wave 2, 2014-2017, N = 15 023). The presence of myopia was determined from a parent questionnaire and validated by the use of a visual aid. The population prevalence of myopia was calculated. Based on the KiGGS wave 2 data, potential risk factors for myopia were identified by means of logistic regression. Results The prevalence of myopia at the age of 0-17 years in Germany…

Reply to "Heparan Sulfate in Baculovirus Binding and Entry of Mammalian Cells"

2014

(1), we investigated the interaction ofbaculovirus and mammalian cell surface heparan sulfate pro-teoglycans (HSPG). The data show that baculovirus requiresHSPG sulfation, particularly N- and 6-O-sulfation, to bind andtransduce mammalian cells. We also show that baculovirus asso-ciates specifically with syndecan-1 (SDC-1) but not with othersyndecans or glypicans.As discussed in the article, HS has previously been shown to beinvolved in glycoprotein 64 (gp64)-mediated baculovirus bindingonto mammalian cells. Heparin and heparinase I and II treatmentof cells have also been shown to prevent the virus binding (2, 3).The role of HS in baculovirus entry was further studied in ourarticle (1). Bindi…
