Introduction: Abdominal angiostrongyliasis is an infrequently diagnosed disease because it is little known and is usually well tolerated. Methods: We carried out a systematic review with PubMed as a search engine for the MedLine database, and we analysed the clinical, epidemiological and analytical parameters of this disease. Results: In total, reports of 27 case have been found, together with a series of 116 patients, which were later augmented up to 194 patients. In the results, we have observed a predominance of male patients, and Costa Rica, Brazil and the United States as the main countries of origin. Typical symptoms include abdominal pain on the right iliac fossa, with leukocytosis and eosinophilia. Discussion: There are some serological diagnostic methods, although lack of standardization leads to most of the diagnoses being reached via pathology. Surgery is the usual treatment approach. Although there are medical options, this is a controversial subject because of the low number of cases published in the literature, which implies an absence of solid studies.

尊重环境并与之融合CKK Jordanki音乐厅位于历史悠久的市中心周围的绿环内,俯瞰着维斯瓦拉河。为了使新建筑在自然环境和建筑环境中显得和谐,在设计体量的方向和高度时需要特别小心。因此,该建筑只占据了场地的一半,另一半则留作公园,并且高度尽可能低,以避免遮挡河上的景观。所达到的视觉效果是一个自然物体,一块卧于缓坡草甸上的天然岩石。

Gebra谷位于中Bransfield盆地的斜坡上，该盆地是一个年轻的、断裂活动强烈的南极洲半岛内的裂谷盆地。盆地后期发生了一系列大规模的滑坡，现在的Gebra谷是所谓“Gebra—Magia滑坡复合体”的一部分。滑坡复合体构成了块体坡移的主体部分，包括两个大型泥石流谷。本文的研究结果是根据多波束测深，高一极高频地震剖面资料得出的。通过对地貌沉积特征以及地震层序分析，对Gebra泥石流谷的沉积演化史作了新的解释。

Coumaric acid can be obtained from basic hydrolysis of coumarin, through a reaction process consisting on opening the lactone ring and cis-trans isomerization. Parameters such as reaction time, temperature, NaOH concentration, solvent and reaction atmosphere, have been thoroughly studied and analyzed, in order to determine the appropriate conditions for the maximum conversion efficiency of coumarin into coumaric acid. Experimental results show that the best conditions are a 1 hour reaction time, at 160℃, with a 20% sodium hydroxide aqueous solution, and in an inert reaction atmosphere.

The pecan nut is considered one of the most important dried fruits in the world by its classification as healthy food. The nutritional balance in the harvest is crucial for its impact on the production, quality and content of bioactive compounds. This research was carried out in the city of Aldama, Chihuahua (Mexico), where doses of mineral and organic fertilization were tested in L25 Taguchi structure with 6 factors and 5 levels by factor: nitrogen (N) 0 - 240 kg·ha-1, phosphate (P2O5) 0 - 120 kg·ha-1, potassium (K2O) 0 - 100 kg·ha-1, calcium (CaO) 0 - 400 kg·ha-1, liquid humus 0 - 3600 L·ha-1 and solid humus 0 - 8000 kg·ha-1. An average yield of 2.2 t·ha-1 was obtained;145 nuts per kilogram, 60% of the edible part of the nut. The total phenolic content was 225.9 mg gallic acid g-1 and the antioxidant capacity was 180.9 mg Trolox g-1. It is concluded that the factor with the greatest impact on yield, quality and antioxidant capacity in pecan nut was nitrogen. It was also found that the combination of mineral and organic fertilization helps to maintain the production and quality ranges of the nut. In turn, these factors contribute to the increase in the phenolic strength and antioxidant capacity. The optimal fertilization dosis to obtain the maximum levels in production of 3.2 t·ha-1;decrease the number of nuts per kilogram to 135, increase the percentage of the edible part of the nut to 61.8%, the increase in the total phenolic content to 318.6 mg of gallic acid g-1 and in the antioxidant capacity with 187.2 mg of Trolox g-1, was 184 kg·ha-1 of N, 107.4 kg·ha-1 of P2O5, 50 kg·ha-1 of K2O y 2777 L·ha-1 of liquid humus. Finally, the mineral fertilization complemented with organic fertilization is considered a good fertilization strategy for pecan trees and its possible benefits to health and the environment.

This paper analyzes the effect of woodlot size and land-use intensity on the species richness of vascular plants, birds, beetles, and ants in Castanea sativa (chestnut) woodlots of the northwestern Iberian Peninsula included in the category “9260 Castanea sativa woodland”, “Annex I, DC 92/43/European Community”. The results show that the surface area of the woodlot did not affect the richness of vascular plants and ants but did affect birds and beetles. The level of abandonment of the woodlot affected only the richness of vascular plants, while the use level had no significant impact on species richness of any of the groups. The degree of maturity of the woodlot, estimated by the tree-trunk circumference, determined only the richness of plants but not that of different groups of animals. In conclusion: 1) Plants and animals responded differently to woodlot size, abandonment, and the degree of maturity of the woodlots;2) Traditional agricultural practices do not negatively affect the biodiversity of the chestnut woodlots of the northwestern Iberian Peninsula or favor plant diversity;and 3) A traditional use of these woodlots may continue to play an important role in maintaining the diversity of plant species in the area.

Extracts of 40 green, black or oolong high quality tea samples from China, Japan or India among others, have been prepared according to the manufacturer instructions and assayed for total polyphenols content using the Folin-Ciocalteu phenol reagent. In addition, the antioxidant activity was assessed by the CUPRAC method and the free-radical scavenging activity was determined using the antioxidant-promoting decay of the stable free-radical DPPH. Caffeine and the most important catechins were identified using RP-HPLC previously validated method. Results from this study suggest that teas, even though they content similar amounts of caffeine, differ considerably in polyphenolic content and therefore in antioxidant and free-radical scavenging activities, depending on the part of the plant used and the process applied to the material for the preparation of the final tea presentation. Correlations among Folin-Ciocalteau’s reactivity of tea samples, the neocuproine reactivity, the DPPH decolourization and the HPLC analysis suggest that the antioxidant activity is due essentially to polyphenolic compounds present in teas, mainly EGCG. The best extraction method of tea powder was the one indicated by dealers. In general, the richest samples belong to green teas and the poorest samples belong to the black teas.
