The trace elements chemistry of Bartlett Pond, a small shallow wetland pond in Laredo, Southern Texas, was sampled to evaluate the dynamics of trace elements impacts on water quality and ecosystems ecology of the pond. Two types of fish (bass and tilapia) were also sampled to see the trace element accumulation in different parts of their body. The concentrations of trace elements in water samples were found in the following order: Fe ≫Sb > Pb > As ≫Co > Tl > Cr > Cd within Bartlett Pond. Overall, the water quality of the pond is unacceptable for drinking and any other purposes as trace element concentrations (e.g. As, Cd, Co, Cr, Pb, Fe, Sb and Tl) are exceedingly higher (several fold) than the WHO and US EPA guidelines. Predictive and correlation analysis shows that most trace elements exhibit a strong positive correlation among them indicating the same anthropogenic sources and biogeochemical processes regulate these trace elements within the pond. Distributions of the trace elements in water exhibit different shapes mostly as positively skewed distribution for As, Cd, Co, Cr, and Tl, symmetrical distribution for Fe and almost symmetrical distribution for Pb and Sb. Concentrations of As, Co and Tl accumulated much higher in different parts of the Bass than Tilapia fish. The concentrations of As, Tl, Co, and Sb appeared significantly higher in different parts of the body of both Bass and Tilapia than the maximum SRM certified values. Accumulation of these contaminants in fish tissues pose increased health risks to humans who consume these contaminated fish although fishing is prohibited. Anthropogenic activities in the region primarily degrade the whole pond ecosystem ecology of the Bartlett Pond and waters of this pond to be not recommended for any use. These findings may be useful for the scientific community and concerned authorities to improve understanding about these precious natural resources and conservation of the ecosystem ecology.

Embryoprotein TWIST distribution in breast cancer cells MDA-MB-231 treated with 5-Fluorouracil and malnutrition

引用

Journal of Biomedical Science and Engineering 2011年第12期4卷 750-754页

作者： Jesica Escobar-Cabrera Angelina Rodríguez-Torres Laura berumen-Segura Guadalupe García Alcocer 不详

TWIST is a transcription factor that belongs to the family of helix-loop-helix proteins involved in metastasis with essential role regulating cell movement during early development, as well as in the tumor progression and metastasis of many cancers including breast cancer. It will be interesting to study the relation among cancer chemotherapy, malnutrition and the transcription factors like TWIST in order to explore the risk to metastasis. We used breast cancer line MDA-MB-231. Cell cultures were treated with 5-Fluorouracil (5-Fu), as well as changes in serum and nonessentials amino acid (NEAA), to explore the cell viability and the cellular distribution of TWIST by immunocytochemistry. Our results indicate that cell viability decreased significantly with 5-Fu treatment whereas no changes were observed in malnutrition treatment. On the other hand, TWIST protein significantly increased its distribution in cytoplasm of treated groups with malnutrition as well as in those treated with 5-Fu compared with the control. These results suggest that TWIST translocation was modified by the treatments and further studies are necessary to suggest that TWIST could be a tag protein to avoid metastasis.

Natural Science 2011年第4期3卷 319-322页

作者： R. A. Silva-Molina M. E. alvarez-Ramos E. OrrantiA Borunda J. Parra-berumen E. Gallegos-Loya E. Torres-Moye D. Lardizabal A. Duarte-Moller 不详

This work shows an optical and structural study of glycine sodium nitrate crystals. This study was supported with the respective X ray diffracttion and Second-Harmonic Generation signal detection by using a little variant to the Kurtz- Perry method. The goal of this work is to obtain the right pH that modifies the charge of glycine sodium nitrate system in order to obtain the best second harmonic emission. Furthermore with the change on the charge on the aminoacid, it is observed how it modifies the optical properties in the glycine sodium nitrate complex.

The genetic microarrays give to researchers a huge amount of data of many diseases represented by intensities of gene expression. In genomic medicine gene expression analysis is guided to find strategies for prevention and treatment of diseases with high rate of mortality like the different cancers. So, genomic medicine requires the use of complex information technology. The purpose of our paper is to present a multi-agent system developed in order to improve gene expression analysis with the automation of tasks about identification of genes involved in a cancer, and classification of tumors according to molecular biology. Agents that integrate the system, carry out reading files of intensity data of genes from microarrays, pre-processing of this information, and with machine learning methods make groups of genes involved in the process of a disease as well as the classification of samples that could propose new subtypes of tumors difficult to identify based on their morphology. Our results we prove that the multi-agent system requires a minimal intervention of user, and the agents generate knowledge that reduce the time and complexity of the work of prevention and diagnosis, and thus allow a more effective treatment of tumors.

Effects of Estradiol on 5-HTsA and 5-HT2c Receptor Immunolabeling in Rat Hippocampus

Steroid hormones participate in the modulation of serotonergic transmission, including the regulation of synthetic and metabolic enzyme production, as well as receptor and transporter activity. The changes of 5-HT5A and 5-HT2c immunolabeling induced by steroids in the hippocampus ofovariectomized rats were studied in this work. Densitometric analysis in rat hippocampi were carried out for adjacent brain coronal immunolabeled sections after treatment with subcutaneous injections of vehicle, estradiol, progesterone or the combination of both steroids in ovariectomized rats. Exposure to estradiol and the combination of estradiol and progesterone significantly reduced the 5-HT5A-like immunosignal in the CA 1 region while progesterone did not induce changes. On the other hand, exposure to the combination of estradiol and progesterone or estradiol alone increased the 5-HT2c immunosignal in the same region. These results indicate that estradiol is involved in the discrete regulation of serotonin receptors 5-HT5A and 5-HT2c in rat hippocampus.
