Constructed wetlands(CwW)are well known nature-based systems for water *** study evaluated the efficiency and effectiveness of seven domestic wastewater treatment systems based on horizontal flow CWs in Jarabacoa,the Dominican *** results showed that the CWs were efficient in reducing the degree of contamination of wastewater to levels below the Dominican wastewater discharge standards for parameters such as the 5-day biochemical oxygen demand(BOD5)and chemical oxygen demand,but not for the removal of phosphorus and fecal *** addition,a horizontal flow subsurface wetland in the peri-urban area El Dorado was evaluated in terms of the performance of wastewater treatment in tropical climatic *** concentrations of heavy metals,such as zinc,copper,chromium,and iron,were found to decrease in the effluent of the wetland,and the concentrations for nickel and manganese tended to *** levels of heavy metals in the effluent were lower than the limit values of the Dominican wastewater discharge *** construction cost of these facilities was around 200 USD per population equivalent,similar to the cost in other countries in the same *** study suggested some solutions to the improved performance of CWs:selection of a microbial flora that guarantees the reduction of nitrates and nitrites to molecular nitrogen,use of endemic plants that bioaccumulate heavy metals,combination of constructed wetlands with filtration on activated carbon,and inclusion of water purification processes that allow to evaluate the reuse of treated water.

波斯胡桃(Juglans regia L.)是用于装饰工业的一种森林物种,需要适当的管理才能生产出经济效益好的高质量原木。由于种间关联和管理水平可以提高林分生产力,因此本研究的创新之处在于评估波斯胡桃在不同混合种植中以及在适度的管理强度的纯人工林中的表现。在两种截然不同的管理方案下种植纯林和混交林后,连续7年每年对波斯胡桃的生长、直度和存活率进行测定。在第7年时,记录所有人工林中病害情况。在每种管理强度下,除纯林外,检验三种混交林:仅与主要森林物种混交、主要森林物种和黑桤木(Alnus glutinosa L.,伴生种)混交,以及主要物种和灌木俄罗斯橄榄(Elaeagnus angustifolia L.,保育种)混交。利用重复生长数据对人工林类型与管理方案之间的交互作用进行检验。研究发现人工林类型与管理方案的交互作用显著,表明在管理水平高和低的条件下,人工林效应存在不同的机制。与纯林相比,在低管理水平下,有保育灌木混交的波斯胡桃的树高增加了78%、直径生长增加了53%。同样,在管理强度不高的情况下,与灌木混交有更多的健康益处(胡桃枯萎病的发生率低于单一栽培)和更好的直度。在高管理强度下(灌溉、施肥、抚育和频繁修剪),与俄罗斯橄榄混交时这些有益效应消失。因此,波斯胡桃种植园的具体选址设计取决于可预见的管理强度。

Effect of Ultraviolet Radiation on Hsp70 Protein Expression in HaCaT Cells

引用

World Journal of Nuclear Science and Technology 2024年第1期14卷 59-71页

作者： Sergio Hugo Sánchez Rodríguez Jesús Rodríguez vergil Manuel Venancio Muñoz Juárez Kevin Said Ramírez Dávila Luis Martín garcía Ortiz Germán Flores Cortés Luz Elena Vidales Rodríguez Jesús Adrián López David Alejandro garcía López Laboratorio de Biología Celular y Neurobiología Unidad Académica de Ciencias Biológicas Universidad Autónoma de Zacatecas Zacatecas México Laboatorio de Bacterias y Hongos Filamentosos Unidad Académica de Ciencias Biológicas Universidad Autónoma de Zacatecas Zacatecas México Laboratorio de MicroRNAs Unidad Académica de Ciencias Biológicas Universidad Autónoma de Zacatecas Zacatecas México

Ultraviolet radiation by its wavelength is divided into: UVA, UVB and UVC. Only UVA and UVB manage to penetrate the ozone layer, but due to anthropological activities, all of them are capable of interacting with humans to a greater or lesser extent, and can generate adverse effects such as cellular stress when interacting with intra-and extracellular biomolecules. The skin is the first organ in contact with UV radiation, and the stress it generates can be analyzed by the expression of a bioindicator of cellular damage such as Hsp70. Therefore, the objective of the project was: to determine the effect of UVA, UVB and UVC radiation on HaCaT epithelial cells, by analyzing the expression of Hsp70. Materials and methods: HaCaT cells were cultured in vitro, which were irradiated with UVA, UVB and UVC light at different doses, to subsequently determine the degree of Hsp70 expression by Immunodetection by PAGE-SDS and Western Blot. Results: Basal expression of Hsp70 was observed in no irradiated HaCaT cells. When HaCaT cells were irradiated with UVA, UVB, UVC, an increase in this Hsp70 protein was observed. With UVA, a higher degree of expression was observed at a time of 30 minutes of irradiation. With UVB the highest expression shifted to a time of 20 minutes. With UVC, overexpression was observed after 10 minutes. Conclusion: UV radiation generates cellular stress on HaCaT cells, evaluated by the stress bioindicator Hsp70. According to the wavelength of UV radiation, those that have a shorter wavelength have a greater potential for cellular damage, such as UVC.

Groundwater Quality and Its Impact on Health: A Preliminary Evaluation of Dental Fluorosis in Julimes, Chihuahua, Mexico

引用

Journal of Water Resource and Protection 2020年第7期12卷 545-557页

作者： Aida verónica Ontiveros-Terrazas Alejandro Villalobos-Aragón Vanessa verónica Espejel-garcía Daphne Espejel-garcía Facultad de Ingeniería Universidad Autónoma de Chihuahua Chihuahua México

Medical Geology can be defined as the branch of geology dealing with the relationship between natural geological aspects and health in organisms (humans and animals), trying to determine the influence of ordinary environmental factors on the geographical distribution of health issues. The main goals of this research were: 1) to evaluate the severity of dental fluorosis (DF) and fluoride concentration in groundwater, used for human consumption, as an indicator of overexposure to fluorides, 2) to estimate the Community Fluorosis Index (CFI) in the Julimes municipality in Chihuahua, Mexico. Nine water samples were collected in four locations in the Julimes area: Hacienda Humboldt, La Regina, Colonia San Jose, and Julimes. Samples were collected and stored in accordance with the Mexican standard (NOM-014-SSA1-1993). All the samples exceeded the maximum permissible limit established in the modified Mexican standard (NOM-127-SSA1-1994) of 1.5 mgL-1 for fluoride in water for human consumption. Average concentrations of 2.74 mgL-1 were found in Colonia San Jose, 2.19 mgL-1 in La Regina, 2.17 mgL-1 in Julimes and 2.06 mgL-1 in Hacienda Humboldt. Dental Fluorosis diagnosis was evaluated using the Dean Index and the CFI applied to residents. A total of 100 inhabitants were examined, with interviews and oral examinations also carried out. Dental Fluorosis prevalence was 92% overall for the municipality, while for Colonia San Jose was of 100%, of 88.89% for Hacienda Humboldt, 88.24% for Julimes and 96% for La Regina. Dental Fluorosis’ severity for the Julimes municipality was distributed as follows: 2% normal, 6% questionable, 8% very mild, 13% mild, 19% moderate, and 52% severe. An average CFI was found for the four localities of 3.02 points, with a very notable impact on public health.
