全谷物热门趋势

古老谷物如今成了厨艺界的宠儿,的确,它们是健康的。近年来,当提到给饮食加点谷物,全麦粉获得了所有的赞誉。但是,今天的超级明星是古老谷物。在小麦成为舞台焦点的很久以前,它们是主要材料。现代的小麦、大米和玉米经过杂交或基因修饰的加工。古老的谷物并没有,它们的种植方法几个世纪以来始终如一。热门趋势或大肆宣传？古老谷物荣登餐饮协会＂2016热门推荐＂食材榜单。

粮谷类粉尘的细胞毒作用

从国内外文献报导及对粮食加工厂工人的职业卫生调查结果都显示了接触高浓度粮谷尘的粮工的上呼吸道,眼、咽、鼻等粘膜有相当比例的阳性症状及慢支、慢咳等患病率增高,与对照组比较,显示小气道功能的肺功能指标均有明显的下降,有部分工人接触谷尘后有谷物热等急性症状发生。

粮谷工血清总IgE水平分析

谷物粉尘是一种混合性有机粉尘,含有多种致敏原。接触谷尘能引起过敏性疾患:如过敏性哮喘、过敏性鼻炎、谷物热等。IgE是Ⅰ型变态反应的重要介质,IgE介导的免疲反应可能与过敏性疾患有关。本文通过对有谷物热史的工人进行血清总IgE水平分析,以了解谷物热与Ⅰ型变态反应的关系。

Antioxidant Capacity and Total Phenol Content of Commonly Consumed Indigenous Foods of Asian Tropical Regions

In order to screen the antioxidant capacity of commonly consumed indigenous foods of tropical region, vegetables, fruits, tea, oil seeds, legumes, spices and cereal were analyzed. Among the vegetables, green chili showed the highest total oxygen radical absorbance capacity （ORACFL） and lipophilic ORAC （L-ORACFL）; whereas, bean showed highest hydrophilic ORAC （H-ORACFL） content. The H-ORACFL of vegetable samples varied between 2.26 to 23.08 ~tmol of Trolox equivalent （TE）/g of fresh weight （FW） and L-ORACFL content widely varied from 0.20 （sweet pumpkin） to 16.95 （green chili）. The range of H-ORACFL values of fruits showed large variation （0.45-178 Ixmol of TE/g FW）. All four different types of tea showed high H-ORACFL （1,295.84-2,709.11 lamol of TE/g）, in contrast to negligible amount of L-ORACFL. In legumes, H-ORACFL content ranged from 16.22 to 140.54; whereas, L-ORACFL ranged from 4.43 to 25.78. Porso millets showed higher L-ORACFL value （19.4） as compared to H-ORACFL （0.8）. In case of spices, L-ORACFL content varied from 29.75 ± 0.00 to 1,575.24 ± 39.63, which is considerably higher as compared to H-ORACFL （61.68 ± 1.71 to 272.82± 1.05） content. Comparatively, spices showed much higher H-ORACFL values as compared to fruits analyzed. In case of selective vegetables, fruits and tea samples, the total phenol content was highly correlated with the H-ORACFL content.

Characterization of Starch Granules Affected by Processing in Some Cereal Foods

To understand how baking processes influence starch quality, twelve samples of cereal foods products have been studied. Damaged starch determined by a-amylase hydrolysis to characterize and quantify the molecular composition of cereal foods starches treated with different conditions during processing that had been physically damaged to different extents, by preparation and processing provide the physicochemical data to understand more fully the effects of mechanical damage on amylase, amylopectin content and differential scanning calorimetric （DSC） for selected cereal foods products. There were significant difference between treatments in term of damaged starch content of cereal foods flours which were 0.64% to 36.40%, while the DSC results for the starches were the gelatinisation onset （To）, peak temperature （Tp） and conclusion temperature （To）, and temperatures of selected food starches ranged from 34.86 ℃ to 75.20 ℃, 54.04 ℃ to 85.94 ℃, and 63.5 ℃ to 95.16 ℃. There were significant differences between all cereal foods starches in term of amylose and its contents ranged from 70.3% to 87% and also there were significant differences between the amylopectin content of cereal foods flours ranged from 13.3% to 29.6%.

REVIEW OF RIGHT VENTRICULAR FAILURE:GENERAL CONSIDERATION

Right ventricular failure(RVF)is a complicated syndrome with multiple etiologies.RVF relates to pulmonary hypertension,left ventricle failure,and congenital heart diseases.The origin of its pathway is based on pathological gene expression and concomitant diseases.Diagnosis of RVF is a serious problem for clinicians,but none of the criteria in current clinical practice provides uncontaminated information on either systolic or diastolic function.Perioperative assessment and bedside monitoring of right ventricle function have to be revised and widely used.Right ventricle function in transplant patients demands different evaluation using biomarkers or/and autopsy.Treatment of RVF has surgical and non-surgical approaches;both are still in development and need further clarification.

Impacts of reforestation on woody species composition,species diversity and community structure in dry-hot valley of the Jinsha River,southwestern China

To understand the impacts of reforestation on woody species composition,species diversity and community structure,seven plantation forests in dryhot valley of the Jinsha River in Southwest China were investigated,with adjacent wastelands,natural shrub grassland and a natural forest as references.Species importance value,species richness,species heterogeneity and Sorenson similarity index between plantations and the natural forest were analyzed.Results indicated that compared to wastelands and natural shrub grassland,reforestation improved species diversity and community structure,and more forest woody species found suitable habitats in plantations.Species diversity in understory of plantations and Sorenson similarity index were significantly negatively correlated with stem density in mature plantations(26-31 years old).Higher species diversity and Sorenson similarity index existed in mature sparse plantations due to lower stem density and more tree species planted initially.In contrast,reference natural forest,with species heterogeneity of 2.28 for shrub layer,showed the highest species diversity.It would take a long time for species composition and diversity to recover through reforestation in a dry-hot valley.Therefore,it was essential to protect remnant natural forests strictly and reforest with suitable management such as lower stem density and increasing genetic diversity of trees planted.
