It is defined as a man's attitude towards his work. The objective of this study was to analyze the theoretical construction of job satisfaction that has been developed by the workers of the creative industries who live in Mexico City. The qualitative method of the informed … …Journal of Social Sciences, Vol. 17, Issue 1 · 6 Feb 2021 · 7,649 accessesView PDF Cite

Research ArticleOpen accessIn the author namesImproved SDA Production in High Lipid Accumulating Strain of Mucor circinelloides WJ11 by Genetic ModificationJunhuan Yang, Md. Ahsanul Kabir Khan, Sergio López-García et al.Stearidonic Acid (SDA; 18:4, n-3) is a ω-3 polyunsaturated fatty acid which is nutritionally important and has pharmaceutical applications. Hence, scientists are trying to construct SDA producing oleaginous microorganisms by genetic modification. Two enzymes, Delta-6 Desaturase (D6D) and ω-3 desaturase catalyze the reactions to produce SDA from Linoleic Acid (LA; 18:2, n-6). But the key enzyme, ω-3 desaturase converts LA … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 23 Mar 2020 · 8,240 accessesView PDF Cite

Research ArticleOpen accessIn the author namesGenetic Diversity and Drug Resistance of Mycobacterium tuberculosis Complex Isolates and Nontuberculous Mycobacteria Identification from Presumptive Tuberculosis Cases in Oaxaca, MexicoNakamura-Lopez Yuko, Valencia-Carmona Oscar Daniel, Martinez-Cruz Perla Monica et al.Tuberculosis (TB) is a re-emerging health problem worldwide. In Mexico, information about genetic diversity and drug resistance of Mycobacterium Tuberculosis complex (MTBc) is limited. Samples from 463 Presumptive TB cases were tested for TB by smear, culture and PCR, from which 19.2% were identify as MTBc and 16% as nontuberculous mycobacteria. MTBc isolates were characterized by Large Sequence Polymorphisms (LSPs), … …American Journal of Infectious Diseases, Vol. 16, Issue 1 · 9 Feb 2020 · 7,159 accessesView PDF Cite

Research ArticleOpen accessIn the author namesWeissella cibaria Fungistatic Activity against Fusarium spp. affecting Yellow PitahayaLeidy Johana Valencia-Hernández, Karina López-López, Liliana Serna-CockFungistatic activity of a Lactic-Acid Bacteria (LAB) was assessed in vitro while isolated from its rumen fluid, against Fusarium oxysporum and Fusarium fujikoroi, basal-rot related species in yellow pitahaya. Fed batch was used to reproduce said LAB. Fungistatic activity kinetic tests were performed on the ferment (S1) and on two of the fractions obtained through centrifugation, supernatant (S2) and biomass … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 10 Dec 2016 · 7,978 accessesView PDF Cite

Research ArticleOpen accessIn the author namesStructural Consequences of the Polymorphism Q223R in the Human Leptin Receptor: A Molecular Dynamics StudyJonathan P. Carrillo-Vázquez, Brenda Chimal-Vega, Beatriz Zamora-López et al.Leptin Receptor (LEPR) is a component of a signaling pathway related to appetite and energy expenditure. Single Nucleotide Polymorphisms (SNP) of Leptin receptor gene (lepr) have been proposed as possible modulator of adipose tissue and body weight. The main phenomenological consequence reported of these SNPs is the modulation of the LEP-LEPR interaction promoting the weight gain. Particularly, Q223R polymorphism has … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 23 Sep 2013 · 7,835 accessesView PDF Cite

Research ArticleOpen accessIn the author namesIdentification of Pharmacological Targets Combining Docking and Molecular Dynamics SimulationsIlizaliturri-Flores Ian, Rosas-Trigueros Jorge Luis, Carrillo-Vazquez Jonathan Pablo et al.Studies that include both experimental data and computational simulations (in silico) have increased in number because the techniques are complementary. In silico methodologies are currently an essential component of drug design; moreover, identification and optimization of the best ligand based on the structures of biomolecules are common scientific challenges. Geometric structural properties of biomolecules explain their behavior and interactions and … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 21 Mar 2013 · 8,128 accessesView PDF Cite

Research ArticleOpen accessIn the author namesG-2548A Leptin Promoter and Q223R Leptin Receptor Polymorphisms in Obese Mexican SubjectsP. Carrillo-Vazquez Jonathan, Lopez-Alcantar Jeronimo, Chimal-Vega Brenda et al.Leptin interaction with its receptor in the hypothalamus stimulates a specific signaling cascade that results in the synthesis of anorexigenic and orexigenic peptides in order to regulate food intake and energy expenditure. Many polymorphisms in leptin (lep) and leptin receptor (lepr) genes have been associated with body weight. In particular, G-2548A in the lep promoter and Q223R in lepr variants … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 12 Feb 2013 · 8,641 accessesView PDF Cite

Research ArticleOpen accessIn the author namesOsmolarity of Coconut Water (Cocos nucifera) Based Diluents and their Effect Over Viability of Frozen Boar SemenBottini Luzardo, M. Centurion Castro, F. Alfaro Gamboa et al.Problem statement: Boar sperm cells are sensitive to the freezing process, which compromises viability of frozen-thawed sperm. In a constant search for minimizing or suppressing sperm cell damage caused by the temperature and osmolarity changes during the freezing process, crioprotective and antioxidant substances have been added to the freezing media, such as coconut water, in order to increase the viability … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,115 accessesView PDF Cite

Research NotesOpen accessIn the author namesOvarian Follicular Dynamics in Caqueteño Creole Cattle Breed at the Colombian Amazon PiedmontLópez-Rojas Robinson, Celis-Parra Gustavo, Tovar-Claros Gilberto et al.Caqueteño creole cattle breed is part of the eight Colombian creole cattle breeds. These breeds are characterized by having great adaptive potential to the environmental conditions in which they are found and allowing them greater productive efficiency. Caqueteño creole cattle is a breed in danger of extinction according to parameters referenced by FAO, since it is a population of cattle … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 3 May 2019 · 8,508 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDouble Working Day in Female Higher Education Teachers in Mexico CityMaría del Carmen López GarcíaNowadays, women are fully integrated to all the productive sectors of life.
