Phthalates are esters of phthalic acid and aliphatic alcohols. It is widely used in everyday life, and can be used as a plasticizer, solvents and additives in many products, from food packaging to items of general use. Plastic materials are widely used in food industry and potentially can be source of phtalates in food. Phtalates can be present in food as a result of contamination of food. Phtalates in food, as a result of contamination of food or migration from packaging can jeopardiye human health. This work provides an overview of the presence of phthalates in food packaging, its migration into food, as well as the negative impact on human health by consuming and inhaling them.

Gluten contains two fractions, which are represented in equal amounts. These are soluble gliadins and insoluble glutenins. Glutenin fraction is responsible for the dough and gluten viscoelastic properties. The dominant type of protein in glutenins are LMW glutenins. The aim of this paper was to examine the influence of solvent type and column temperature on the separation effectiveness of LMW glutenins. Extraction was performed with 50% (v/v) ethanol, 1-propanol and isopropanol to which Tris-HCl (0.05 mol/l, pH=7.5), urea (2 mol/l) and dithioerythritol (1%) were added. Separation of LMW glutenins was performed on HPLC Agilent Techologies 1260 Infinity apparatus. After the extraction with 50% (v/v) ethanol, 1-propanol and isopropanol to which Tris-HCl (0.05 mol/l, pH=7.5), urea (2 mol/l) and dithioerythritol (1%) were added, the highest number of proteins was observed after extraction with 50% (v/v) 1-propanol and at a column temperature of 40°C (Xsr=20, respectively RC=69.56%), and the lowest number at a column temperature of 45°C (Xsr=14.17, respectively RC=66.42%). The obtained results were read at a wavelength of 210 nm. After the extraction of LMW glutenins with 50% (v/v) ethanol, 1-propanol and isopropanol to which Tris-HCl (0.05 mol/l, pH=7.5), urea (2 mol/l) and dithioerythritol (1%) were added and detected at a wavelength of 280 nm, the highest number of proteins was observed after extraction with 50% (v/v) isopropanol and at a column temperature of 50°C (Xsr=24.17, RC=56.47%) and the lowest number of proteins after extraction with 50% (v/v) ethanol and at a column temperature of 50°C (Xsr=12.17, RC=56.45%).
谷蛋白含有两种成分,它们的数量相等。它们是可溶性麦胶蛋白和不溶性麦胶蛋白。谷蛋白部分负责面团和面筋的粘弹性。谷蛋白中主要的蛋白质类型是LMW谷蛋白。考察了溶剂类型和柱温对低分子量谷蛋白分离效果的影响。以50% (v/v)乙醇、1-丙醇和异丙醇为萃取剂,加入三羧酸盐(0.05 mol/l, pH=7.5)、尿素(2 mol/l)和二硫代赤藓糖醇(1%)。采用Agilent technologies 1260 - Infinity高效液相色谱仪对LMW谷蛋白进行分离。以50% (v/v)乙醇、1-丙醇和异丙醇分别加入Tris-HCl (0.05 mol/l, pH=7.5)、尿素(2 mol/l)和二硫赤四醇(1%)进行提取后,50% (v/v) 1-丙醇在40℃柱温下提取的蛋白质数量最多(Xsr=20, RC=69.56%), 45℃柱温下提取的蛋白质数量最少(Xsr=14.17, RC=66.42%)。所得结果在210 nm波长处读取。用50% (v/v)乙醇、1-丙醇和异丙醇分别对LMW谷蛋白进行提取,其中加入Tris-HCl (0.05 mol/l, pH=7.5)、尿素(2 mol/l)和二硫赤四醇(1%),在280 nm波长下检测,50% (v/v)异丙醇在50℃柱温下(Xsr=24.17, RC=56.47%)提取的蛋白数最多,50% (v/v)乙醇在50℃柱温下(Xsr=12.17)提取的蛋白数最少,其中50% (v/v)乙醇在50℃柱温下(Xsr=12.17)提取的蛋白数最少。RC = 56.45%)。

High prevalence of cerebrovascular insults (CVI) and their comorbidity with depression additionally makes difficult not just quality of life, also its serious obstacle to all measurements and attempts of patient’s rehabilitation. The scope of work is to show frequency of depression after CVI ischemic type in whole its specifics in order to age of patients, gender, localization of lesion, as well as on level of physical handicapping. International classification of disease (MKB-10), Hamilton scale of depression (HAM-D-17) and Barthel index scale of disability were used for diagnosis. Statistical analysis was performed in SPSS programme. Among 103 patients with CVI 43 of them (41.7%) were found with consequential depression what was monitored in following six months after CVI. From total number of depressions after CVI in the age of 58 years old 14 (32.6%) were found, and in the age between 59-63 years old there were 17 (39.5%) found. In the later ages that percentage was significantly lower. This result had proved significant connection between age group and depression status (p<0.05): χ² (3, n = 103) = 12.24; p=0.007, Cramer’s V=0.34. Depression appearance after CVI in relation to genders has showed difference. Depression was marked at 16 (25.8%) male and 27 (65.8%) at female patients: χ² (1,n=103)=14.67; p=0.0002;Phi=0.4. Localization of lesion was significant in emergence of depression. In frontal part were found at 21 examinees, in basal ganglia at 16 and rest of localizations were found at 6 examinees: Depressions presence were more found at lesion localizations in left hemisphere, but no statistical importance. There were some correlation between level of physical disability and depression severity.
脑血管损伤(CVI)的高发及其与抑郁症的合并症不仅给患者的生活质量带来了困难,而且严重阻碍了患者康复的所有测量和尝试。工作范围是显示CVI缺血类型后抑郁的发生频率,其整体特征与患者的年龄、性别、病变部位以及身体残疾程度有关。采用国际疾病分类量表(MKB-10)、汉密尔顿抑郁量表(HAM-D-17)和Barthel残疾指数量表进行诊断。采用SPSS软件进行统计分析。在103例CVI患者中,43例(41.7%)在CVI后6个月的监测中发现继发性抑郁。CVI术后出现抑郁的年龄为58岁14例(32.6%),59 ~ 63岁17例(39.5%)。在后来的年龄,这一比例明显降低。年龄与抑郁状态有显著相关(p<0.05): χ 2 (3, n = 103) = 12.24;p=0.007,克莱默氏V=0.34。CVI后抑郁的出现在性别上存在差异。男性患者有16例(25.8%)抑郁,女性患者有27例(65.8%)抑郁:χ 2 (1,n=103)=14.67;p = 0.0002;φ= 0.4。病灶的定位在抑郁症的出现中具有重要意义。21例在额部,16例在基底节区,6例在其余部位。左半球病变部位出现较多的凹陷,但无统计学意义。身体残疾程度与抑郁严重程度之间存在一定的相关性。

Increased levels of cholesterol and blood sugar are public health problems that are increasingly important, because they cause micro and macro complications. In order to prevent this condition, terms of modifying the style of life and eating habits need to be changed. This paper has determinated the way in which the effect of a lifestyle reduces cholesterol and blood sugar levels, with a particular emphasis on the effect that diet and modern lifestyle have on diabetes, that is, on the increase in cholesterol levels. The aim of the paper is to highlight problems that arise from increased levels of cholesterol and blood sugar, but also to present possible solutions to these problems, or to improve the condition of patients. The research was carried out on a sample of 80 respondents from the Republic of Srpska, where the respondents were divided into two groups (experimental group and control group). Respondents from the experimental group had, before and after a 30-day application of a health diet, measured values of cholesterol and blood sugar.

Metabolic syndrome is a set of several different pathological conditions and risk factors that are often the cause of many unwanted cardiac and cerebrovascular occurrences. It is highly represented around the world, especially in countries with excessive and inadequate nutrition, insufficient physical activity of the population and obesity, with a constant growth trend. The work included 1052 patients with HTA of which DM was 309 (29.4%). Out of the total number of 1052 patients with metabolic syndrome there were 675 (64.2%) patients. Observing certain determinants of the metabolic syndrome HTA was present in all observed patients. Low HDL cholesterol values were found in 503 (74.5%) patients and the lowest incidence was hyperglycaemia (252 mg / 37.3%). Implemented pharmacological treatment measures have led, in most patients, the blood pressure to optimal or normal. The effect of pharmacological therapy on glycaemic value in patients with metabolic syndrome led to the normalization of glycaemia in majority of patients. The results achieved have improved the quality of life of patients and motivated them for further treatment.
代谢综合征是几种不同的病理状况和危险因素的集合,通常是许多不希望发生的心脑血管疾病的原因。它在世界各地都有很高的代表性,特别是在营养过剩和营养不足、人口体育活动不足和肥胖的国家,并呈不断增长的趋势。纳入1052例HTA患者,其中DM 309例(29.4%)。在1052例代谢综合征患者中,有675例(64.2%)患者。观察到代谢综合征的某些决定因素HTA存在于所有观察的患者中。503例(74.5%)患者出现低HDL胆固醇值,高血糖发生率最低(252 mg / 37.3%)。实施的药物治疗措施使大多数患者的血压达到最佳或正常水平。药物治疗对代谢综合征患者血糖值的影响导致大多数患者血糖恢复正常。所取得的结果改善了患者的生活质量,并激励他们进一步治疗。

Air quality has been a major concern throughout the world, Nigeria inclusive. The monitoring of air quality involves indoor and outdoor air quality. In this study, our concern was on indoor air quality. The aim of this study was to assess the air quality of residential homes (17), classrooms (3), hospitals (2), offices (5), Shops (2), and laboratories (5) in Akure, Nigeria in terms of formaldehyde (HCHO), total volatile organic compound (TVOC), Particulate matter (PM1.0; PM2.5, and PM10). A Multifunction Air Detector was used for the assessment using the manufacturers’ procedures and the locations were identified using a Mini GPS. The results revealed as follows: HCHO (0.001-0.030 mg/m3), TVOC (0.003-362 mg/m3), PM1.0 (004-014 µg/m3), PM2.5 (006-020 µg/m3), and PM10 (006-022 µg/m3). The results obtained were below the 24 h pollution recommended standards (0.1 mg/m3- HCHO; TVOC; 10-20 μ/m3 PM) of EPA and WHO. Statistically, there were correlations within the pollutants and weather. The Indoor air quality (IAQ) depicted the areas as ‘good,’ and toxicity potential (TP) were below unity. Although the locations looked safe, it is recommended that constant monitoring of the indoors should be ensured and proper ventilation should be provided.
空气质量一直是全世界关注的主要问题,包括尼日利亚。空气质量监测包括室内空气质量和室外空气质量。在这项研究中,我们关注的是室内空气质量。本研究的目的是评估尼日利亚阿库雷的住宅(17)、教室(3)、医院(2)、办公室(5)、商店(2)和实验室(5)的空气质量,包括甲醛(HCHO)、总挥发性有机化合物(TVOC)、颗粒物(PM1.0;PM2.5和PM10)。使用多功能空气探测器根据制造商的程序进行评估,并使用迷你GPS确定位置。结果显示:HCHO (0.001 ~ 0.030 mg/m3)、TVOC (0.003 ~ 362 mg/m3)、PM1.0(004 ~ 014µg/m3)、PM2.5(006 ~ 020µg/m3)、PM10(006 ~ 022µg/m3)。所得结果低于24 h污染推荐标准(0.1 mg/m3- HCHO;TVOC;10 ~ 20 μ/m3 PM)。从统计上看,污染物和天气之间存在相关性。室内空气质量(IAQ)将这些地区描述为“良好”,而毒性潜能(TP)低于1。虽然这些地点看起来很安全,但建议确保对室内进行持续监测,并提供适当的通风。

This paper investigates the impact of accidental release of propane gas in surrounding areas consequences of propane gas leak studying the negative effects on both the environment and individuals. Subject of the research is impact of accidental release of propane gas in in business zone “Ramići-Banja Luka”, Banja Luka. The ALOHA software has been used in this paper to modelling of propane release. The modelling was performed for an accidental release of 4,000 kg propane from unsheltered single storied for one hour. For a typical average atmospheric condition in location, this accidental propane release would cause a red zone of 101 metres (AEGL-3=33,000 ppm), orange zone of 159 metres (AEGL-2=17,000 ppm) and yellow zone of 324 metres (AEGL-1=5,500 ppm) to downwind from the source.

Fish as a food is very acceptable for consumers. Various species of fishes nowdays are everyday on our tables. Fish from north seas are also in high demand from consumers, but it is challeng to keep and transport fish to consumers. Thats why as prevention of spoiling fish before consumation is to keep it on special regime. In our challeng we packaged fish in vaccum and modified atmosphere, and than followed the growth of aerobic bacterias mainly cause of spoilage.
鱼作为食物是很容易被消费者接受的。现在我们的餐桌上每天都有各种各样的鱼。来自北海的鱼也受到消费者的高度需求,但保存和运输鱼给消费者带来了挑战。这就是为什么在食用前要防止鱼变质的原因。在我们的挑战中,我们在真空和改性气氛中包装鱼,然后跟踪好氧细菌的生长,主要是导致腐败的原因。

Aflatoxins as Food Contaminants 黄曲霉毒素作为食物污染物
Pub Date : 2019-07-23 DOI: 10.7251/qol1901033k
Marina Kvaternik, M. Todorovic, M. Nikolic, M. Protić
Mycotoxins are nowadays one of the most known and most frequent chemical food contaminants. Among the listed mycotoxins, aflatoxins are the most important group of mycotoxins in terms of impact on human and animal health. Of the known mycotoxins, aflatoxin B1 is considered the most toxic. The main sources of aflatoxins are cereals, oilseeds, nuts, dried fruit, and spices. The most commonly used screening method for the detection of mycotoxins is the immunoenzyme (ELISA) method. The purpose of this paper is to show the types of foodstuffs and the results of sample analyses of aflatoxin B1 in these foodstuffs carried out at the Institute of Public Health of the Republic of Srpska - Regional Center Doboj in the period from 2011 to 2017, and to propose measures for improvement of supervision in this area, i.e. to recommend certain measures in order to prevent the occurrence of aflatoxins in foodstuffs.
真菌毒素是当今最知名和最常见的化学食品污染物之一。在列出的真菌毒素中,黄曲霉毒素是对人类和动物健康影响最大的一类真菌毒素。在已知的真菌毒素中,黄曲霉毒素B1被认为是毒性最大的。黄曲霉毒素的主要来源是谷物、油籽、坚果、干果和香料。检测真菌毒素最常用的筛选方法是免疫酶(ELISA)法。本文的目的是展示2011年至2017年期间在斯普斯卡共和国公共卫生研究所-多博伊区域中心进行的食品类型和这些食品中黄曲霉毒素B1样本分析的结果,并提出改进该领域监管的措施,即建议采取某些措施以防止食品中黄曲霉毒素的发生。

Athiology of some health disorders and diseases, such as obesity, cardio vascular diseases, diabetes and malignant diseases, can be linked to unbalanced diet started from the earliest days of life. For that reasons, it is very important to adopt proper diet patterns from the earliest days of life. There are few factors influencing choice of food. Food flavoure is one among them. Understanding mechanisms, which later make influence how to accept or reject some food in children, in intrauterine development phase, and after birth period, is of vital significance when we create healthy habbits for children and adult diets.
一些健康失调和疾病的病理学,如肥胖、心血管疾病、糖尿病和恶性疾病,从生命早期就开始与不平衡的饮食有关。因此,从生命早期开始采用适当的饮食模式是非常重要的。影响食物选择的因素很少。食品风味就是其中之一。了解影响儿童、宫内发育阶段和出生后对某些食物的接受或拒绝的机制,对我们培养儿童和成人的健康饮食习惯具有重要意义。
