Zingiber officinale, commonly known as ginger, is a species native of tropical Asia. It is grown and used in tropical countries of America, including Mexico, where it is used for the treatment of throat infections. The aim of this study was to determine the chemical composition of essential oil of Z. officinale rhizome and evaluate their antimicrobial activity. The essential oil was obtained by hydrodistillation, and the chemical composition of the oil was determined by GC-MS. To determine the antimicrobial activity diffusion, agar dilution and radial growth inhibition methods were employed. Microbial growth curves were performed on the strains most susceptible. It was identified 28 compounds in the essential oil, the most abundant were eudesmol (8.19%), γ-terpinene (7.88 %), a-curcumene (7.28%), alloaromadendrene (6.56%), zingiberene (6.06 %), α-pinene (5.76 %), δ-cadinene (3.84%), elemol (3.39%), farnesal (3.45%), E-β-farnesene (3.57%), neril acetate (2.8%) and β-myrcene (2.94%). In antimicrobial activity, the essential oil inhibited the growth of 15 bacterial strains, 3 of yeast fungi and 4 of mycelia fungi. The most susceptible strains were S. aureus FES-I (MIC = 0.25 mg/mL) S. epidemidis FES-C (MIC = 0.5 mg/mL), E. faecalis ATCC 14506 (MIC = 1.0 mg/mL), C. tropicalis (CMI = 0.125 mg/mL) and T. mentagrophytes (CF50 = 0.08 mg/mL). In the microbial growth curves the essential oil showed bactericidal effect on S. aureus FES-I and S. marcescens ATCC 14756 from the first hour of exposure of the strains to oil, eliminating 99.9% of CFU in concentrations of 0.5 and 0.75 mg/mL respectively. The results validate the medicinal use of Z. officinale in the treatment of diseases of possible infectious origin.

Background: New normality is uncertain in every sense, specifically in education and for many health disciplines. Being immersed in COVID-19 pandemics brought serious consequences for mental health, and is very important to handle emotions and stress coping strategies to obtain positive outcomes. Objective: To identify the most frequent emotions, as well as the adaptation strategies to the new normality faced by the students of nursing. Methods: Qualitative and phenomenological research, with the participation of 20 students from both genders in the middle term of nursing career at Faculty of Higher Studies Iztacala, National Autonomous University of Mexico, from August to November 2021. Information was collected from a focal group for ten sessions;analysis was according to De Souza Minayo, and there was a signed informed consent letter from participants. Results: Four categories emerged with sub-categories. Category I Maximized emotions. Sub-categories: 1) Frustration, anger, disappointment;2) Personal disappointment, hopelessness, uncertainty;3) Depression. Category II Support elements close to the new normality. Sub-categories: 1) Family communication;2) Education for mental and physical health. Category III Stressing situations that exceeded the student. Sub-category: Disease in lovely ones. Category IV Stress coping strategies. Sub-categories: 1) Friends and relatives that help to get better;2) Family values. Informers pointed out to have maximized emotion, and having no self-control on its negative outcomes occurred;in addition, the situation was not favorable at home with several losses of loved ones, as well as a poor economy that threatened students to give up studies. Conclusion: Emotions facing this new normality are very important and should be attended to, their proper handling will result in a new learning of socio-emotional abilities, stress coping strategies development, better adaptation and informed decisions taken.

Influence of Surfactant and Salt Concentration on the Rheological Properties of Three Different Microstructures of Associative Polyelectrolytes Obtained by Solution Polymerization

引用

Journal of Modern Physics 2014年第14期5卷 1387-1396页

作者： areli I. Velazquez-Garcia Gregorio Cadenas-Pliego Claudia C. Rivera-Vallejo Enrique J. Jiménez-Regalado Centro de Investigación en Química Aplicada (CIQA) Saltillo México

The rheological properties of three different microstructures of hydrophobically modified alkalisoluble polymers (telechelic, multisticker and combined) in the presence of various concentrations of anionic surfactant and salt (NaCl) were investigated. Associative polymers containing both ionic sites and small number of hydrophobic groups were obtained, and their thickening properties in aqueous solutions, were investigated. Solution polymerization was used for obtaining the different polymers. Relationships between hydrophobe, sodium dodecyl sulfate (SDS) and NaCl concentration are proposed. Owing to the competition between attractive hydrophobic interaction and repulsive electrostatic interactions, such hydrophobically modified polymers exhibit various rheological behaviors in aqueous solutions, depending on microstructure of polyelectrolyte, SDS and NaCl concentrations.

Breast cancer is the number one cause of can- cer deaths among Hispanic women in the United States, and in Mexico, it recently became the primary cause of cancer deaths. This malign- nancy represents a poorly understood and un- derstudied disease in Hispanic women. The ELLA Binational Breast Cancer Study was es- tablished in 2006 as a multi-center study to as- sess patterns of breast tumor markers, clinical characteristics, and their risk factors in women of Mexican descent. We describe the design and implementation of the ELLA Study and provide a risk factor comparison between women in the U.S. and those in Mexico based on a sample of 765 patients (364 in the U.S. and 401 in Mexico). Compared to women in Mexico, U.S. women had significantly (p < 0.05) lower parity (3.2 vs. 3.9 mean live births) and breastfeeding rates (57.5% vs. 80.5%), higher use of oral contraceptives (60.7% vs. 50.1%) and hormone replacement therapy (23.3% vs. 7.6%), and higher family history of breast cancer (15.7% vs. 9.0%). Re- sults show that differences in breast cancer risk factor patterns exist between Mexico and U.S. women. We provide lessons learned from the conduct of our study. Binational studies are an important step in understanding disease pat- terns and etiology for women in both countries.
