    • A versatile oblique plane microscope for large-scale and high-resolution imaging of subcellular dynamics 
      Sapoznik, Etai; Chang, Bo-Jui; Huh, Jaewon; Ju, Robert J.; Azarova, Evgenia; Pohlkamp, Theresa; Welf, Erik S.; Broadbent, David; Carisey, Alexandre F.; Stehbens, Samantha J.; Lee, Kyung-Min; Marín Valdés, Arnaldo; Hanker, Ariella B.; Schmidt, Jens C.; Arteaga, Carlos L.; Bin, Yang; Kobayashi, Yoshihiko; Tata, Purushothama Rao; Kruithoff, Rory; Doubrovinski, Konstantin; Shepherd, Douglas P.; Millett Sikking, Alfred; York, Andrew G.; Dean, Kevin M.; Fiolka, Reto P. (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, ...
    • Chromatin Packing in Normal and Teratozoospermic Human Ejaculated Spermatozoa 
      BUSTOS‐OBREGON,; LEIVA, (1983)
      Chromatinpackung in normalen Spermatozoen und solchen von Männern mit Teratozoospermie Normalgeformte ovale und Teratozoospermie‐Spermatozoen wurden mittels verschiedener Untersuchungstechniken miteinander verglichen ...
    • The DNA-Binding Protein HU has a Regulatory Role in the Acid Stress Response Mechanism in Helicobacter pylori 
      Almarza, Oscar; Núñez, Daniel; Toledo Araya, Héctor (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 ...
    • Kinship determination using DNA markers Estudios de parentesco mediante marcadores del ADN: Experiencia en ... 
      Jorquera González, Hugo; Acuña P, Mónica; Cifuentes L, Lucía (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 ...
    • Non random DNA evolution 
      Valenzuela, Carlos Y. (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 ...
    • Origins of changos. Mitochondrial DNA analysis suggests Chinchorro culture fishermen ancestry Origen de los ... 
      Rothhammer Engel, Francisco; Moraga, Mauricio; Santoro, Calogero M.; Arriaza, Bernardo T. (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 ...
    • Phenazine 5,10-dioxide derivatives as hypoxic selective cytotoxins: Part II. Structure-activity relationship ... 
      Cerecetto, Hugo; González, M.; Lavaggi, M. L.; Aravena, M. A.; Rigol, C.; Olea Azar, Claudio; Azqueta, A.; López de Ceráin, Adela; Monge, A.; Bruno, A. M. (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 ...
    • Role of Human Papillomavirus in Penile Carcinomas Worldwide
