Site-specific cleavage of ribosomal RNA in Escherichia coli-based cell-free protein synthesis systems
(PLoS ONE, 2016)Cell-free protein synthesis, which mimics the biological protein production system, allows rapid expression of proteins without the need to maintain a viable cell. Nevertheless, cellfree protein expression relies on ... -
Morphometry and subpopulation structure of Holstein bull spermatozoa: Variations in ejaculates and cryopreservation straws
(2016)Sperm quality is evaluated for the calculation of sperm dosage in artificial reproductive programs. The most common parameter used is motility, but morphology has a higher potential as a predictor of genetic quality. ... -
Morphometric comparison by the ISAS® CASA-DNAf system of two techniques for the evaluation of DNA fragmentation in human spermatozoa
(Instituto Tecnológico de Costa Rica. Escuela de Agronomía. Sede San Carlos., 2016)DNA fragmentation has been shown to be one of the causes of male infertility, particularly related to repeated abortions, and different methods have been developed to analyze it. In the present study, two commercial kits ... -
Identification of the agr Peptide of Listeria monocytogenes
(Frontiers in Microbiology, 2016)Listeria monocytogenes (Lm) is an important food-borne human pathogen that is able to strive under a wide range of environmental conditions. Its accessory gene regulator (agr) system was shown to impact on biofilm formation ... -
Low back pain among office workers in three Spanish-speaking countries: Findings from the CUPID study
(Instituto Tecnológico de Costa Rica. Escuela de Ingeniería en Seguridad Laboral, 2017)Objectives—To assess differences in the prevalence and incidence of low back pain (LBP) and associated disability among office workers in Costa Rica, Nicaragua and Spain. Methods—Data were collected at baseline (n=947, ... -
Four-channel WDM transmitter with heterogeneously integrated III-V/Si photonics and low power 32 nm CMOS drivers
(Journal of Lightwave Technology, 2016)We experimentally demonstrate a novel four-channel wavelength division multiplexing transmitter operating at 1.3 μm wavelength employing heterogeneously integrated III-V/Si photonic circuit copackaged with low-power ... -
Flexible transmitter employing Silicon-segmented Mach–zehnder modulator with 32-nm CMOS distributed driver
(Journal of Lightwave Technology, 2016)We propose a flexible optical transmitter for shortreach optical interconnects that includes a silicon photonic segmented Mach-Zehnder modulator (MZM) driven by a distributed six-channel 32nm SOI CMOS driver integrated ... -
Holosalud y turismo por mujeres campesinas en Los Santos
(Instituto Tecnológico de Costa Rica, 2016)Holosalud es una iniciativa comunitaria fundada en 1995 como proyecto de la Asociación Proyectos Alternativos –PROAL-, orientado a la integración de mujeres de comunidades campesinas en la zona Los Santos. Su quehacer ... -
Tracking dipeptides at work-uptake and intracellular fate in CHO culture
(AMB Express, 2016)Market demands for monoclonal antibodies (mAbs) are steadily increasing worldwide. As a result, production processes using Chinese hamster ovary cells (CHO) are in the focus of ongoing intensification studies for maximizing ... -
Towards autotrophic tissue engineering: photosynthetic gene therapy for regeneration
(Biomaterials, 2016)The use of artificial tissues in regenerative medicine is limited due to hypoxia. As a strategy to overcome this drawback, we have shown that photosynthetic biomaterials can produce and provide oxygen independently of blood ... -
The release of wastewater contaminants in the Arctic: A case study from Cambridge Bay, Nunavut, Canada
(Scopus, 2016)The treatment of municipal wastewater in the Arctic is challenging due to a variety of financial, operational, climatic and technical issues. To better understand the efficacy of current wastewater treatment in this ... -
Synthesis, properties, and two-dimensional adsorption characteristics of 5-amino[6]hexahelicene
