The present study is conducted with the purpose of determining the chemical characteristics of groundwater that supplies 16 wells in the state of Coahuila, which are used for different human activities. Sampling was conducted in January 2011. For 56% of the fifteen wells tested, analysis did not detect the presence of aluminum;however, wells 2, 3, 6, 8 and 13 had concentrations above the permissible limit established by the Mexican standard NOM-127-SSA1-1994. For cadmium, only the well 3 was above the Norm. Meanwhile, iron was above the permissible limit in eight wells (2, 4, 5, 6, 9, 12, 13 and 15). Lead exceeded the limit in wells 6, 7, 9, 10, 11 and 12. In general, for the rest of the parameters listed in the Norm, values were below allowable limits. By using Piper diagrams, it was observed that in general, the waters tested showed characteristic calcium bicarbonate. By establishing a matrix of correlations between chemical parameters, it was observed that the highest significant correlations occurred among carbonate hardness, calcium, lead and total alkalinity, with r2 values greater than 0.82. Also, high correlations were found between some metal species, suggesting a common origin. The allowed Principal Component Analysis and Cluster Analysis establish the associations between all analyzed physicochemical parameters, and they also determine the wells with similar characteristics.

Pernicious anemia: New insights from a gastroenterological point of view

引用

World Journal of Gastroenterology 2009年第41期15卷 5121-5128页

作者： edith Lahner Bruno Annibale Department of Digestive and Liver Disease University Sapienza 2nd Medical School Ospedale Sant'Andrea Via di Grottarossa 1035 00189 Roma Italy

Pernicious anemia （PA） is a macrocytic anemia that is caused by vitamin B12 deficiency, as a result of intrinsic factor deficiency. PA is associated with atrophic body gastritis （ABG）, whose diagnosis is based on histological confirmation of gastric body atrophy. Serological markers that suggest oxyntic mucosa damage are increased fasting gastrin and decreased pepsinogen I. Without performing Schilling＇s test, intrinsic factor deficiency may not be proven, and intrinsic factor and parietal cell antibodies are use- ful surrogate markers of PA, with 73% sensitivity and 100% specificity. PA is mainly considered a disease of the elderly, but younger patients represent about 15% of patients. PA patients may seek medical advice due to symptoms related to anemia, such as weak-ness and asthenia. Less commonly, the disease is suspected to be caused by dyspepsia. PA is frequently associated with autoimmune thyroid disease （40%） and other autoimmune disorders, such as diabetes mellitus （10%）, as part of the autoimmune polyen-docrine syndrome. PA is the end-stage of ABG. Long- standing Helicobacter pylori infection probably plays a role in many patients with PA, in whom the active infectious process has been gradually replaced by an autoimmune disease that terminates in a burned-out infection and the irreversible destruction of the gastric body mucosa. Human leucocyte antigen-DR genotypes suggest a role for genetic susceptibility in PA. PA patients should be managed by cobalamin replacement treatment and monitoring for onset of iron deficiency. Moreover, they should be advised about possible gastrointestinal long-term consequences, such as gastric cancer and carcinoids.

The evolution of sexual imprinting in socially monogamous populations

Current Zoology 2015年第6期61卷 1043-1061页

作者： edith INVERNIZZI R. Tucker GILMAN Faculty of Life Sciences University of Manchester C. 1249a Michael Smith Building Dover Street Manchester M 13 9PL UK

Sexual imprinting is a common mechanism of mate preference learning. It is thought to influence how traits evolve and in some cases to promote speciation. Recently there has been increasing interest in how sexual imprinting itself evolves. Theoretical work on polygynous mating systems predicts that females will evolve paternal imprinting, which means they learn to prefer phenotypes expressed by their fathers. In nature however, females of some species learn to prefer phenotypes expressed by their mothers instead. We used a dynamical systems model and tools from adaptive dynamics to study how sexual imprinting evolves in species with socially monogamous mating systems. We considered cases in which the target trait for imprinting is un- der viability selection but is not a reliable signal of paternal investment. Thus, the target trait signals the genetic benefits rather than the parental care benefits of mate choice. When mating is socially monogamous and there is some extra-pair patemity, we show that maternal imprinting can be favored over paternal imprinting. Counterintuitively, females often become choosier when selecting social partners in systems where extra-pair mating is more frequent. That is, females may be more selective when choosing social partners that will sire a smaller percentage of their offspring. Our results offer new testable hypotheses, and ad- vance our understanding of the mechanisms that drive the evolution of mate choice strategies in nature .

Protein-Repairing Methionine Sulfoxide Reductases in Photosynthetic Organisms： Gene Organization, Reduction Mechanisms, and Physiological Roles

引用

Molecular Plant 2009年第2期2卷 202-217页

作者： Lionel Tarrago edith Laugier Pascal Rey CEA DSV IBEB Laboratoire d'Ecophysiologie Moleculaire des Plantes B~timent 161 SBVME CEA-Cadarache 13108 Saint-Paul-lez-Durance Cedex France

Methionine oxidation to methionine sulfoxide （MetSO） is reversed by two types of methionine sulfoxide reducrases （MSRs）, A and B, specific to the S- and R-diastereomers of MetSO, respectively. MSR genes are found in most organisms from bacteria to human. In the current review, we first compare the organization of the MSR gene families in photosynthetic organisms from cyanobacteria to higher plants. The analysis reveals that MSRs constitute complex families in higher plants, bryophytes, and algae compared to cyanobacteria and all non-photosynthetic organisms. We also perform a classification, based on gene number and structure, position of redox-active cysteines and predicted sub-cellular localization. The various catalytic mechanisms and potential physiological electron donors involved in the regeneration of MSR activity are then de- scribed. Data available from higher plants reveal that MSRs fulfill an essential physiological function during environmental constraints through a role in protein repair and in protection against oxidative damage. Taking into consideration the ex- pression patterns of MSR genes in plants and the known roles of these genes in non-photosynthetic cells, other functions of MSRs are discussed during specific developmental stages and ageing in photosynthetic organisms.

Risk for gastric neoplasias in patients with chronic atrophic gastritis:A critical reappraisal

引用

World Journal of Gastroenterology 2012年第12期18卷 1279-1285页

作者： Lucy Vannella edith Lahner Bruno Annibale Dipartimento Medico-Chirurgico di Scienze Cliniche Tecnobiomediche e Medicina TraslazionaleSant'Andrea HospitalSchool of MedicineUniversity Sapienza

Chronic atrophic gastritis （CAG） is an inflammatory condition characterized by the loss of gastric glandular structures which are replaced by connective tissue （non-metaplastic atrophy） or by glandular structures inappropriate for location （metaplastic atrophy）. Epidemiological data suggest that CAG is associated with two different types of tumors： Intestinal-type gastric cancer （GC） and type I gastric carcinoid （T I GC）. The pathophysiological mechanisms which lead to the development of these gastric tumors are different, It is accepted that a multistep process initiating from Helico- bacterpylori-related chronic inflammation of the gastric mucosa progresses to CAG, intestinal metaplasia, dysplasia and, finally, leads to the development of GC. The T I GC is a gastrin-dependent tumor and the chronic elevation of gastrin, which is associated with CAG, stimulates the growth of enterochromaffin-like cells with their hyperplasia leading to the development of T I GC. Thus, several events occur in the gastric mucosa before the development of intestinatype GC and/ or T I GC and these take several years. Knowledge ofCAG incidence from superficial gastritis, its prevalence in different clinical settings and possible risk factors as- sociated with the progression of this condition to gastric neoplasias are important issues. This editorial intends to provide a brief review of the main studies regarding incidence and prevalence of CAG and risk factors for the development of gastric neoplasias.
