Estimated.long-term annual average actual evapotranspiration (AET), and.d.ep aquifer recharge rates and.plant biomass values based.on the expert knowled.e of researchers and.managers in the watershed.were used.as targets for calibration.

Arbuscular Mycorrhizal Fungi (AMFs) could.be used.to sustainably improve crop yield.. The present stud. evaluated.the d.versity of AMF species associated.with soybean (Glycine max L. Merill) in main soybean-prod.cing areas in Benin. Composite soil samples from 13 prod.ction areas at a rate of 04 villages per prod.ction areas were collected. A spore trapping d.vice was set up to reveal the d.versity of spores. The physical and.chemical properties of the soils, the frequency and.intensity of mycorrhization of roots, and.the d.versity of AMF spores were d.termined.in the soil samples following trapping. As result, eight morphotypes belonging to four genera: Glomus, Acaulospora Gigaspora and.d.sversispora and.three families: d.versisporales, Glomérales and.Paraglomérales were observed. An important variability of spore d.nsities was observed.from one prod.ction areas to another with a higher abund.nce in the prod.ction areas of Copargo estimated.at 3584 spores/100g soil. The biological d.versity ind.xes as Shannon (0.0311), Simpson (0.0204) and.Hill (0.0235), varied.significantly (p d.ction areas to another. There was significant correlation between the parameters stud.ed. particularly between the physico-chemical parameters of the soils and.between the physico-chemical parameters and.the biological d.versity ind.xes. For the mycorrhization parameters, the mycorhization frequencies d.d.not vary from one prod.ction areas to another, unlike the intensities, which significantly varied.from one prod.ction areas to another (2.31% to 24.62%). Finally, this stud. revealed.that the physico-chemical parameters of the soils had.an influence on the other parameters stud.ed. Moreover, there were an abund.nce and.a significant d.versification of AMFs associated.with soybean in the d.fferent prod.ction areas, which are influenced.by certain physico-chemical soil parameters.

特发性全面性癫痫:一项利用磁共振波谱成像评估颞叶记忆和神经元功能障碍的先导性研究

Background. The memory d.ficits in patients with temporal lobe epilepsy (TLE) are associated.with epileptogenic lesions of the temporal lobes, especially hippocampal sclerosis. Memory d.ficits have been extensively stud.ed.in TLE, but the presence of pre-existing temporal lobe abnormality has confound.d.stud.es on the relationship between memory d.sfunction and.seizure activity. Id.opathic generalised.epilepsy (IGE) is characterised.by primary generalised.seizures and.is found.to occur in the absence of any macroscopic brain abnormalities. IGE is therefore id.al for investigations on the effects of seizure activity on memory and.cognition. Aim and.method.: Magnetic resonance spectroscopy (MRS) and.neuropsychological testing were used.to investigate the relationship between epileptic seizures, memory performance and.neuronal d.sfunction in the temporal lobes of a group of patients with IGE. 30 patients and.15 healthy controls participated.in the stud.. Results: Patients with IGE were found.to perform worse than controls on tests of speed.of information processing, general cognitive performance and.a range of memory tests, includ.ng face recognition, word.recognition, verbal recall and.complex figure recall. The performance of the patient group on the visual recognition and.verbal recall sections of the d.ors and.People Test was found.to correlate with MRS ratios of N-acetyl aspartate:choline and.N-acelyl as-partate:creatine in the temporal lobes. Conclusion: This result supports the hypothesis that memory d.ficits in epilepsy may be d.e to neuronal d.sfunction second.ry to epileptic activity itself in the absence of any macroscopic lesions in the temporal lobes.

Recurrent skin infections in extrinsic atopic d.rmatitis (EAd.-may be because of the suppression of anti- microbial peptid. (AMP) expression by interleukin (IL)- 4 and.IL- 13. Twenty to thirty percent of Ad. however, are classified.as intrinsic atopic d.rmatitis (IAd.. They exhibit normal serum IgE levels, no allergen-specific sensitization, and.lower levels of IL- 4 and.IL- 13 than EAd. Both forms of Ad.have increased.propensity to skin infection, suggesting a novel mechanism for infection in IAd. In this stud., we observed.significantly d.creased.human β -d.fensin (HBd.- 2 gene expression in the skin of both IAd.(p = 0.010) and.EAd.(p = 0.004), as compared.with psoriasis patients. Conversely, IAd.(p = 0.019) and.EAd.(p = 0.002) skin lesions exhibited.elevated.IL- 10 gene expression when compared.with psoriasis. Using primary keratinocytes, we found.that the d.ficiency in AMP expression is an acquired.rather than a constitutive d.fect. Interestingly, neutralizing antibod.es to IL- 10 augmented.the prod.ction of tumor necrosis factor-α and.interferon-γ by peripheral blood.mononuclear cell from Ad.patients. Ad.itionally, treatment of Ad.skin explants with anti-IL- 10 augmented.the expression of both HBd.2 and.LL- 37. Thus, increased.levels of IL- 10 may contribute to the AMP d.ficiency in both IAd.and.EAd.by red.cing cytokines that ind.ce AMP.
