The separation between the 5′-3′ ends in long RNA molecules is short and nearly constant
(2014-12)"RNA molecules play different roles in coding, decoding and gene expression regulation. Such roles are often associated to the RNA secondary or tertiary structures. The folding dynamics lead to multiple secondary structures ... -
Simple approach for ranking structure determining residues
(2016-06)"Mutating residues has been a common task in order to study structural properties of the protein of interest. Here, we propose and validate a simple method that allows the identification of structural determinants; i.e., ... -
Molecular and biochemical characterization of extracellular tannin acyl hydrolase activity from a Mexican isolate of Aspergillus niger
(2010-12)"Microbial tannase, a hydrolysable tannin-degrading enzyme, is extensively used in manufacture of instant tea, beer, wine, and gallic acid. Aspergillus niger strain, obtained from a Mexican tannery wastewaters rich in ... -
Genotyping of the MTL loci and susceptibility to two antifungal agents of Candida glabrata clinical isolates
(2009-08)"The opportunistic fungal pathogen Candida glabrata is the second most common isolate from bloodstream infections worldwide and is naturally less susceptible to the antifungal drug fluconazole than other Candida species. ... -
Oxidative stress response to menadione and cumene hydroperoxide in the opportunistic fungal pathogen Candida glabrata
(2009-07)"Candida glabrata is an opportunistic fungal pathogen that can cause severe invasive infections and can evade phagocytic cell clearance. We are interested in understanding the virulence of this fungal pathogen, in particular ... -
Dibenzo[1,2,5]thiadiazepines are non-competitive GABAA receptor antagonists
(MDPI, 2013)"A new process for obtaining dibenzo[c,f][1,2,5]thiadiazepines (DBTDs) and their effects on GABAA receptors of guinea pig myenteric neurons are described. Synthesis of DBTD derivatives began with two commercial aromatic ... -
Effect of salt stress, proline, and polyamines on seed germination of Opuntia streptacantha
(2008)"In this study we conducted experiments in order to determine whether polyamines (putrescine, spermidine, and spermine) and proline treatments help to break seed dormancy of Opuntia streptacantha and also if they facilitate ... -
Effects of nitrogen-doped multiwall carbon nanotubes on murine fibroblasts
(2015)"The effect of nitrogen-doped multiwall carbon nanotubes (CNx) on the proliferation of NIH-3T3murine fibroblasts is presented. CNTs were dispersed in distillated water and incubated with mammalian cells in order to evaluate ... -
Proteomic analysis of amaranth (Amaranthus hypochondriacus L.) leaves under drought stress
(2009-04)"Amaranth (Amaranthus hypochondriacus L.) is a plant that produces seed with high protein content, is rich on nutraceutical compounds, and can grow under environmental conditions where most of the basic crops are not able ... -
HR4 gene is induced in the Arabidopsis-Trichoderma atroviride beneficial interaction
(MDPI, 2012)"Plants are constantly exposed to microbes, for this reason they have evolved sophisticated strategies to perceive and identify biotic interactions. Thus, plants have large collections of so-called resistance (R) proteins ... -
Mycobacterium tuberculosis TLR2 agonists LprA, LM and Man-LAM induce notch1 and socs3 transcription
(2011-08)"Mycobacterium tuberculosis employs a number of strategies to subvert host signaling events, leading to its persistence within macrophages. Upon infection, Mycobacterium bovis BCG induce the expression of suppressor of ... -
The Opuntia streptacantha OpsHSP18 gene confers salt and osmotic stress tolerance in Arabidopsis thaliana
(MDPI, 2012)"Abiotic stress limits seed germination, plant growth, flowering and fruit quality, causing economic decrease. Small Heat Shock Proteins (sHSPs) are chaperons with roles in stress tolerance. Herein, we report the functional ... -
A germin-like protein gene (CchGLP) of Capsicum chinense Jacq. is induced during incompatible interactions and displays Mn-superoxide dismutase activity
(MDPI, 2011-10)"A germin-like gene (CchGLP) cloned from geminivirus-resistant pepper (Capsicum chinense Jacq. Line BG-3821) was characterized and the enzymatic activity of the expressed protein analyzed. The predicted protein consists ... -
Changes in angiotensin receptor distribution and in aortic morphology are associated with blood pressure control in aged metabolic syndrome rats
(2016)"The role of the renin-angiotensin system (RAS) in blood pressure regulation in MS during aging is unknown. It participates in metabolic syndrome (MS) and aging regulating vascular tone and remodeling. RAS might participate ... -
Regulación del inicio de la esporulación e histidina cinasas: un análisis comparativo entre bacillus subtilis y el grupo bacillus cereus
(2009-05)"La esporulación, que es una respuesta de quorum sensing, es un proceso de diferenciación celular mediado por moléculas de señalización, señales fisiológicas y ambientales. Se sabe que Bacillus subtilis detecta las señales ... -
HPV genotype distribution and anomalous association of HPV33 to cervical neoplastic lesions in San Luis Potosí, Mexico
(2016-03)" Background: The association of human papillomavirus (HPV) types to neoplastic lesions increase as a function of their oncogenicity and the duration of the infection since lesion severity progresses from low-grade to ... -
