The purpose of this work was to study the thermal characterization of oils extracted from native seeds and fruits of the Argentina, Uruguayan region. This is important because it＇s necessary to find new applications for food industry. Uruguayan wild cardoon seed, Argentinian wild papaya seeds, Argentinian avocado pulp, Argentinian cherimoya seeds, Argentinian grapeseeds and four commercial brands of chia oils were studied. The thermal behaviors of the oils were analyzed on a differential scanning calorimetry （DsC）, TA Instrument, Q20 model equipped with an intercooler. These oils＇ thermal profiles presented differences, which are related to the compositions of fatty acids and triacylglycerols. The thermogram for the chia oil, with a high content of linolenic acid, presented a very important peak at about -40 ℃; whereas, the papaya oil with an oleic acid content of 74%, showed a peak at about -3 ℃. When comparing the thermal behaviors of these oils to commercial brand oils, it was found that the chia oil is similar to the flaxseed oil, the papaya similar to the olive oil and the avocado similar to the rice bran oil. The avocado oil, in particular, presents high solid content at cold store or winter temperatures, which would make its use in those conditions difficult （for example, a cosmetic cream or gourmet oil）. In conclusion, the thermal behavior of one oil sample as determined by DsC provides valuable information with regards to the possible use of new oils of American origin as replacement of usual commercial others.

Plicopurpura pansa is a cultural resource with economic importance since ink can be extracted from it to dye clothes. This snail inhabits the rocky intertidal zone of Mexican Pacific, is found attached to rocks in crevices and holes. The objective was to analyze the P. pansa population structure in Costa Chica of the state of Guerrero based in density, sex ratio, size and weight, besides to realize observations on mating and recruitment, for which quarterly sampling was made during an annual cycle in three beaches. The density was 4.83 snails/m2. sex ratio ranged from 0.76:1.00 to 1.00: 0.96 (F:M). Average size was 20.91 mm. The best represented sizes in females were from 10.5 to 28.5 mm and in males 13.5 to 28.5 mm. Averaged weight was 1.99 g, females showed a coefficient of variation in weight of 96.53%. Recruitment occurred for the entire year. In December 2006 and september 2007 a larger frequency of recruits was shown. sex ratio showed a 1:1 tendency. snail population was characterized by being small sized and in high densities. Weight variations in females were found related to their reproductive cycle.

We report a 35-year-old female patient with hypertrophic cardiomyopathy, left ventricular noncompaction, and Wolff-Parkinson-White EKG pattern. several other family members present the same clinical condition. We speculate that this phenotype is related to the genotypes PRKAG2 and LAMP2 represented by mutations of the genes encoding AMP-activated protein kinase (PRKAG2) and lysosome associated membrane protein 2 (LAMP2).

1、模仿在语言获得中的作用某些关于儿童语言获得研究者认为,模仿与言语获得没有关系(slobin,1967)。早在六十年代,不少人研究了儿童直接模仿成人句子的效果(Brown,Bellugi,1964;Cazden1965)。他们认为,尽管模仿在儿童语音、新词语的获得和习惯语表达方面起着重要作用,但是,并不能说明模仿在儿童句法获得中起作用。slobin(1967)指出,在某种情况下,儿童能对成人的句子正确地模仿,只是能模仿的这些句子比儿童自发的句子(spontaneous sentences)稍长或稍复杂些。我们认为,这种模仿能加强儿童的句法能力,因此有利于儿童下一阶段句法能力的发展。近些年来,Bloom,Hood和Lightbown(1974)提供了儿童早期言语发展的证据,表明有模仿倾向的儿童似乎是通过模仿来掌握新的语义句法关系以及新的词汇、习语。有模仿倾向的儿童在语气材料和上下文知识的处理中是积极的。这些研究涉及到句法,也涉及到发展方面的作用。

作者： Adrián Poblano norma Ballesteros Carmina Arteaga Blanca Flores Teodoro Flores Laboratory of Clinical Neu-rophysiology National Institute of Rehabilitation Mexico City Mexico Laboratory of Cognitive Neurophysiology National Institute of Rehabilitation Mexico City Mexico

We study hearing in a group of infants with Breast-feeding jaundice (BFJ) by means of Transient-evoked otoacoustic emissions (T-EOE) and Brainstem auditory evoked potentials (BAEP) searching for relationship between bilirubin serum levels and auditory dysfunction. Eleven infants born at-term with BFJ were selected for the study. We studied also 11 control age- and gender matched healthy at-term infants without signs of jaundice. T-EOAE studies were performed between 5-7 days after birth, and 3 months later. BAEP studies were performed once. BFJ group infants exhibited lower amplitudes in T-EOE than infants in the control group. These differences disappear at the 3-month evaluation. In BAEP, we observed a significant latency delay of waves I and V in Breast-feeding jaundice group infants. All infants in both groups demonstrated reproducible wave V response at 30 decibels. No significant correlation values were observed between bilirubin serum levels and T-EOE and BAEP variables. Our data suggest that BFJ can result in transient peripheral and central auditory dysfunction. Dysfunction is reversible after treatment of infants with BFJ.

Changes during Cooking Processes in 6 Varieties of Andean Potatoes (<i>solanum tuberosum</i>ssp. Andinum)

引用

American Journal of Plant sciences 2015年第5期6卷 725-736页

作者： Maria E. Jimenez Analia M. Rossi norma C. sammán Instituto superior de Investigaciones Biológicas (INsIBIO) CONICET-UNT e Instituto de Química Biológica “Dr. Bernabé Bloj” Facultad de Bioquímica Química y Farmacia UNT Chacabuco Tucumán Argentina

The value of the native potato varieties grown in Argentinean northwest lies both in their fundamental role as a source of food for the population and in their potential for the development of new products. The aim of this work was to study the changes produced by two common cooking processes (boiling and frying) on the nutritional, textural and functional characteristics of five Andean potatoes varieties. The cooking process (boiling) does not significantly affect the composition of potatoes, but there are losses of vitamin C;a greater loss was observed when they were boiled shelled. In frying potatoes vitamin C is completely destroyed. Resistant starch values between 0.90 and 4.58 g/100g of potato were found for raw Andean varieties;they decreased during the cooking process (boiled) (0.15 to 0.54 g/100g of potato) and increased again to be stored for 48 h at 4°C (0.73 - 1.88 g/100g of potato). The frying process produced an increment in energy value between 92% and 148% according to variety. Regarding to the fracture strength and hardness, no significant differences were observed between the Andean varieties and the control (spunta) at the initial or final stages, but there were differences during the intermediate stages.

BACKGROUND The high prevalence and persistence of Helicobacter pylori(H. pylori) infection, as well as the diversity of pathologies related to it, suggest that the virulence factors used by this microorganism are varied. Moreover, as its proteome contains 340hypothetical proteins, it is important to investigate them to completely understand the mechanisms of its virulence and survival. We have previously reported that the hypothetical protein HP0953 is overexpressed during the first hours of adhesion to inert surfaces, under stress conditions, suggesting its role in the environmental survival of this bacterium and perhaps as a virulence *** To investigate the expression and localization of HP0953 during adhesion to an inert surface and against gastric(AGs) *** Expression analysis was performed for HP0953 during H. pylori adhesion. HP0953 expression at 0,3, 12, 24, and 48 h was evaluated and compared using the Kruskal-Wallis equality-of-populations rank test. Recombinant protein was produced and used to obtain polyclonal antibodies for immunolocalization. Immunogold technique was performed on bacterial sections during adherence to inert surfaces and AGs cells, which was analyzed by transmission electron microscopy. HP0953 protein sequence was analyzed to predict the presence of a signal peptide and transmembrane helices, both provided by the ExPAsy platform, and using the GLYCOPP platform for glycosylation sites. Different programs, via, I-TAssER, RaptorX, and HHalign-Kbest, were used to perform three-dimensional *** HP0953 exhibited its maximum expression at 12 h of infection in gastric epithelium *** technique revealed HP0953 localization in the cytoplasm and accumulation in some peripheral areas of the bacterial body, with greater expression when it is close to AGs *** analysis revealed the presence of a signal peptide that interacts with the transmembrane region and then allows the release of the protein
