(Elife, 2020)We present an oblique plane microscope (OPM) that uses a bespoke glass-tipped tertiary objective to improve the resolution, field of view, and usability over previous variants. Owing to its high numerical aperture optics, ...
-
(Universitaria, 2016)El análisis del ADN nos permite definir un perfil genético de cada individuo y de poblaciones de individuos y comprender la huella biológica que han dejado nuestros ancestros en el genoma actual. En este contexto, este ...

(Universidad de Chile, 2014)
-
(1983)Chromatinpackung in normalen Spermatozoen und solchen von Männern mit Teratozoospermie Normalgeformte ovale und Teratozoospermie‐Spermatozoen wurden mittels verschiedener Untersuchungstechniken miteinander verglichen ...
-
(Springer, 2016)A comparative study about the electrochemical response of glassy carbon electrode modified with four different carbon nanomaterial (CNM) against dsDNA is reported. The CNM used were oxidized and nonoxidized multiwalled ...
-
(Wiley-Blackwell, 2015)Background: Bacterial genomes are compacted by association with histonelike proteins to form a complex known as bacterial chromatin. The histonelike protein HU is capable of binding and bending the DNA molecule, a function ...
-
(Wiley-VCH Verlag, 2014)Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a major health problem worldwide. In this work, we report the development of palladium and platinum metal complexes with 5-nitrofuryl-containing ...
-
(WILEY-V C H VERLAG GMBH, 2007-07)We studied the reactivity of peroxynitrite and different nucleic acid molecules using DNA electrochemical biosensors. SIN-1 (3-morpholinosydnonimine) has been used for the simultaneous generation of NO- and superoxide, ...
-
(2010)In this study the interaction between new benzimidazole molecules, 2-(2-nitrophenyl)-1H-benzimidazole (NB) and N-benzoyl-2-(2-nitrophenyl)-benzimidazole (BNB), with dsDNA and ssDNA was assessed at pH 7.4. Using differential ...
-
(2011)This work reports the electrochemical response of the complex between dsDNA and PEI formed in solution and at the surface of glassy carbon electrodes (GCE) modified with a dispersion of multi-walled carbon nanotubes in ...
-
(Universidad de Chile, 1997)
-
(Nature, 2020)The matrilineal long-finned pilot whale presents an antitropical distribution and is divided into two subspecies, one in the temperate seas of the Southern Hemisphere and the other restricted to the North Atlantic and ...
-
(Elsevier, 2020)We aimed to study the effect of vanadium(V) exposure on cell viability, nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) and to elucidate if these effects can be reverted by co-exposure to V and manganese (Mn). HepG2 cells ...
-
(2008)Background: Autosomal and Y chromosome short tandem repeats (STRs) and mitochondrial DNA polymorphisms are the most commonly used molecular tools for determination of kinship. Aim: To report a revision of 1,120 kinship ...
-
(Nature, 2020)Knots are remarkable topological features in nature. The presence of knots in crystallographic structures of proteins have stimulated considerable research to determine the kinetic and thermodynamic consequences of threading ...
-
(Springer, 2020)Bisphosphonates are the most commonly prescribed drugs for the treatment of osteoporosis and other bone illnesses. Some of them have also shown antiparasitic activity. In search of improving the pharmacological profile of ...
-
(1997)A model for testing molecular evolution is proposed. Randomness of recurrent mutation is defined based on isotropy and zero convariance among nucleotide sites. Assuming an equal rate of mutation for the bases A, T, G, and ...
-
(2010)Sophisticated molecular genetics techniques allow the typification and posterior comparison of antique haplogroups and mitochondrial DNA sequences from prehistoric groups with contemporary populations. This adds a chronological ...
-
(2006)The synthesis and evaluation as hypoxic selective cytotoxins of new derivatives of 2-amino or 2-hydroxyphenazine 5,10-dioxide are described. The compounds were developed as structural analogs of other bioreductive compounds ...
-
(Nature, 2022)Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong ...
