Prostate cancer (PCa) is the second leading cause of mortality in men, the present diagnosis method being based on serum prostate-specific antigen (PSA) screening, with low specificity and overestimated values. A combined untargeted and targeted metabolomic study of metabolites from blood serum samples collected from healthy (n=11), hyperplasia (n=39) and prostate cancer (n=83) patients is presented, using the HPLC-(ESI+) QTOF-MS analysis. The profile of blood serum samples provided complementary information obtained from Base Peak Chromatograms and Dissect chromatograms. Based on dissect chromatograms, two different methods of statistical analysis were used, either based on the instrument software with automated alignments with/without normalization (Profile Analysis), or based on manual alignment followed by statistical analysis (Unscrambler10.X software). Both methods used the unsupervised Principal Component Analysis which discriminated between normal, hyperplasia and cancer patients. The second method allowed a better discrimination between groups, by qualitative and quantitative parameters (m/z values versus peak areas) and better possibilities to identify the molecules responsible for such discriminations.Considering the retention time interval (6-17 min), four molecules to be considered as putative biomarkers for hyperplasia or prostate cancer were identified: Prostaglandins E2/G2, Pregnenolone/ethyltestosterone, Lysophosphatidylcholine18:2/0:0, Galactosylceramide (18:1/24:1).By using larger patient cohorts and optimizing the data processing and chemometric analysis, more reliable biomarkers for prostate hyperplasia and cancer can be discovered and quantified. This preliminary study has had promising findings for the implementation and validation of metabolomic targeted analysis in clinical laboratories.
前列腺癌(PCa)是导致男性死亡的第二大原因,目前的诊断方法是基于血清前列腺特异性抗原(PSA)筛查,特异性低且估值过高。采用HPLC-(ESI+) QTOF-MS分析方法,对健康(n=11)、增生(n=39)和前列腺癌(n=83)患者的血清代谢物进行了非靶向和靶向代谢组学研究。血清样品的轮廓提供了从基峰色谱和解剖色谱获得的补充信息。基于层析图,使用了两种不同的统计分析方法,一种是基于仪器软件进行自动校准(带/不带归一化),另一种是基于手动校准然后进行统计分析(Unscrambler10)。X软件)。两种方法都使用无监督主成分分析来区分正常、增生和癌症患者。第二种方法可以通过定性和定量参数(m/z值与峰面积)更好地区分群体,并更好地识别导致这种区分的分子。考虑到保留时间间隔(6-17 min),确定了前列腺增生或前列腺癌的四种可能的生物标志物:前列腺素E2/G2、孕烯醇酮/乙基睾酮、溶血磷脂酰胆碱18:2/0:0、半乳糖神经酰胺(18:1/24:1)。通过使用更大的患者队列,优化数据处理和化学计量学分析,可以发现和量化更可靠的前列腺增生和癌症的生物标志物。这项初步研究为临床实验室中代谢组学靶向分析的实施和验证提供了有希望的发现。

Grasslands have a great importance for humans around the world being the beginning of many of our food products. Since there is a direct connection between soil, plant and climate, scientist became concerned of this interaction and studies were conducted to describe this connection and to improve output in grasslands with best measures possible. The experiment established in Petrova, Maramureș in the autumn of 2012 is used to obtain information on how different types of manure influence the vegetation and the output on permanent grasslands. Since there are other studies in this field, in different areas of Romania and in other countries, results can be compared so that a greater picture can be made on how organic fertilizers influence the quality and quantity of forage.
草原对世界各地的人类来说非常重要,因为它是我们许多食物的起源。由于土壤、植物和气候之间有直接的联系,科学家们开始关注这种相互作用,并进行了研究,以描述这种联系,并尽可能采取最佳措施提高草地的产量。2012年秋季在马拉穆雷涅的佩特洛娃建立的实验用于获取关于不同类型的粪肥如何影响永久草原上的植被和产量的信息。由于在罗马尼亚和其他国家的不同地区也进行了这一领域的其他研究,因此可以比较结果,以便更全面地了解有机肥如何影响牧草的质量和数量。

  Metabolomics is an important “omics” technology, complementary to genomics and proteomics, as parts of systems biology, giving information (qualitative fingerprints and quantitative profiling) as a mirror of cell and extracellular metabolic activity. A cohort of small metabolites are involved in the control and regulation of cellular functions, as intermediates or final products, their presence or levels being useful for the early diagnosis of different pathologies. Bioinformatics tools are mandatory for a future “computational” metabolomics, needed to manage large number of experimentally acquired data obtained from biological samples (plants, animal or human tissues). This review presents updated information about different high-throughput analytical techniques and data acquisition  software (1-2), the pre-processing of data, converted to specific matrices, further processed by specific normalization and alignment  procedures (3), then analysed by statistical univariate and multivariate chemometric and /or statistical techniques (4), identifying biomarkers by comparison with databases (5), and finally elucidating the networks and pathways (6). New software is available for data conversion, pre-processing, alignment algorithms, bucketing, normalization, underlying the challenges and comparisons with international data bases. Finally, the accurate identification of individual molecules as biomarkers, either evaluated by untargeted metabolomics techniques (Principal Component Analysis - PCA), Cluster Analysis - CA) or supervised ones (Partial Least Square Discriminant Analysis (PLS-DA) is presented. The accurate identification of metabolites and their involvement in metabolic networks and pathways became possible by well-established databases (HMDB, LIPID MAPS, KEGG, etc.), to validate all experimental data. Bioinformatics is a sine-qua-non tool, to be used and valorised by untargeted or targeted metabolomics, as an integrated technology in systems biology.     Â

Reproductive Indices of Rainbow Trout (Oncorhynchus mykiss) Females from a Trout Farm 虹鳟(Oncorhynchus mykiss)雌鱼的生殖指数
Andrada Ihuț, V. Mireșan, D. Cocan, C. Răducu, C. Lațiu, D. Pop
Rainbow Trout (Oncorhynchus mykiss) breeding females have been studied from the standpoint of phenotypic characteristics and breeding indices for establishing future protocols of selection and improvement. The relative fecundation (RF) has been determined to a medium value of 335.88 ± 17.723 g and a variability coefficient of 52.77%. The high value of the variability coefficient is due to the fact that this is the first breeding generation of trout nursery and has not been submitted to any selection and improvement activities up to the present. From the breeding performance standpoint, the medium value of the number of eggs (TNE) obtained has been of 8127.44 ± 478.532, the medium egg weight (EW) has been of 0.06 ± 0.001g, the medium diameter of one egg (ED) = 4.16 ± 0.029 mm and the medium volume of one egg (EV) has been of 65.63 ± 1.223 mm3. The following breeding indices have also been calculated: gonadosomatic report (GR), Behning fertilizing coefficient (BFC) and the Williams absolute fecundity indices (WAFI). The outcome results have been the following: GR = 14.82 ± 0.587; BFC = 16.82 ± 0.563; WAFI = 5.77 ± 0.333. The values of the correlations point out the necessity of breeding selection work in order to improve the breeding performances.
对虹鳟鱼(Oncorhynchus mykiss)雌鱼进行了表型特征和育种指标的研究,为今后的选择和改良方案的制定奠定了基础。相对受精率(RF)为335.88±17.723 g,变异系数为52.77%。变异系数的高值是由于这是鳟鱼苗圃的第一代育种,到目前为止还没有进行任何选择和改进活动。从养殖性能上看,获得的中粒蛋数(TNE)为8127.44±478.532,中粒蛋重(EW)为0.06±0.001g,中粒蛋直径(ED)为4.16±0.029 mm,中粒蛋体积(EV)为65.63±1.223 mm3。还计算了以下育种指标:性腺报告(GR)、贝宁受精系数(BFC)和威廉姆斯绝对繁殖力指数(WAFI)。结果:GR = 14.82±0.587;BFC = 16.82±0.563;Wafi = 5.77±0.333。相关系数的取值表明,为了提高育种性能,有必要进行育种选择工作。

Some investigations on incidence and infestation level in Cyprinid postodiplostomosis 鲤科鱼双口后病发病率及危害程度调查
O. Negrea, V. Mireșan, C. Răducu, G. Onaciu, O. Negrea, C. Lațiu, C. Daniel
In our study, we sampled 82 fish specimens as follows: 62 rudd ( Scardinius erythrophthalmus ), 8 roach (Rutilus rutilus) and 12 silver bream (Blicca bjoerkna). The sampling was done in A¢aga Mare Lake, Cluj County. The investigations took into account the incidence and infestation levels of fish with Posthodiplostomum cuticola metacercaria. The study results show an incidence of parasitosis of 80.60% for rudd, 75.00% for roach and 25.05% for silver bream. Regarding the intensity of infestation (low, medium and high), low levels of infestation are predominant (rudd - 72%; roach 83.30%; silver bream - 66.60%). The preferred body area for metacercaria (in descending order) are as follows: for rudd - 90.00% on the body, 86.00 on the fins and caudal peduncle, and 28.80% on the head; for roach - 50.00% on the body, 66.00% on the fins and caudal peduncle, and 33.00% on the head; for silver bream - 100.00% on the body, 33.00% on the fins and caudal peduncle, and 33.00% on the head.Histopathological sections were taken from musculocutaneous tissue extracted from the dorsal area of fish which was parasitized with cystic metacercariae. The central points of metacercaria is surrounded by a connective structure in the form of a capsule, in which melanocyte-like cells are predominant. Intracytoplasmically, they show a brown-blackish granular pigment which masks the cell nucleus. Perifocally, the inflammatory cell infiltrate is discreet with few mononuclear heterophile cells. Â
本研究共采集了82种鱼类标本,分别为:红眼斑鱼(Scardinius erythrophthalmus) 62种,蟑螂(Rutilus Rutilus) 8种,鲷鱼(Blicca bjoerkna) 12种。采样是在克鲁日县的A¢aga Mare湖进行的。调查考虑了鱼类表皮裂口后囊蚴的发病率和感染水平。研究结果表明,陆克虫、蟑螂和银鱼的寄生率分别为80.60%、75.00%和25.05%。在侵染强度方面(低、中、高),低侵染程度占主导地位(陆克文- 72%;罗奇83.30%;银鲷鱼- 66.60%)。囊蚴的体表优先分布区域(由大到小)为:陆龟-体表90.00%,鳍和尾端86.00%,头部28.80%;蟑螂:身体50.00%,鳍和尾肢66.00%,头部33.00%;对于银鱼——身体上有100.00%,鳍和尾鳍上有33.00%,头部有33.00%。从寄生囊性囊蚴的鱼背部提取肌肉皮肤组织,取组织病理切片。囊蚴的中心点被囊状结缔组织包围,其中以黑素细胞样细胞为主。胞浆内可见棕黑色颗粒状色素,掩盖了细胞核。局灶周围,炎性细胞浸润不明显,单核嗜异性细胞较少。一个

Toxicological Tests of Tumolit and Artemisinin Products on Laboratory Mice and Rats Tumolit和青蒿素产品对实验小鼠和大鼠的毒理学试验
C. Oroian, A. Stuparu, V. Gavrila, T. Oroian
This paper presents the experimental results establishing the lethal dose (LD) of the two products considered to have antitumor effect:Tumolit and Artemisinin. For testing, we used an experimental design including two species of gnawers, Swiss mice and Wistar rats. Two experimental groups were used, consisting of 20 Swiss male mice each, as well as two groups of 10 Wistar rats/lot. In interpreting the results of the research and in the development of the experimental protocol, we took into account the toxicity scale after Hodge and Sterner. Initial doses were usedof both products at 200mg / kg / body for each mouse and rat, respectively, administered orallyin single-doses. Between each oral dose, there was one day of rest in order to evaluate possible effects. As mentioned in theProtocol, the dose was increased to500mg dose / kg / body,then to 1000 mg / kg / body, 2000mg / kg / body and then to 5000 mg / kg / body. At this last dose, administration was disrupted in mice. For rats, doses were further increased in three innings to 5000 mg / kg / body, 15,000 mg / kg / body concerned 20,000 mg / kg / body in single oral dose.  The administration was done by gavage in a single dose. There were no toxicity effects reported at any dose level applied, which is why we conclude that the two products are practically non-toxic. Â
本文介绍了两种被认为具有抗肿瘤作用的药物Tumolit和青蒿素的致死剂量(LD)的实验结果。为了进行测试,我们采用了包括两种啮齿动物,瑞士小鼠和Wistar大鼠的实验设计。采用2个实验组,每组瑞士雄性小鼠20只,2组Wistar大鼠10只/批。在解释研究结果和制定实验方案时,我们考虑了霍奇和斯特纳事件后的毒性等级。两种产品的初始剂量分别为每只小鼠和大鼠200mg / kg /体,口服单剂量。在每次口服剂量之间,有一天的休息时间,以评估可能的效果。如议定书所述,剂量增加到500mg剂量/ kg /体,然后增加到1000mg / kg /体,2000mg / kg /体,然后增加到5000mg / kg /体。在最后一次给药时,小鼠的给药中断。对大鼠,三局剂量进一步增加至5000 mg / kg /体,15,000 mg / kg /体,单次口服剂量为20,000 mg / kg /体。Â给药方式为单次灌胃。在任何剂量水平下都没有毒性作用的报告,这就是为什么我们得出结论,这两种产品实际上是无毒的。一个

The Influence of Fodder Additives in Feeds on the Production Performance and Egg Quality of Laying Quails 饲料中饲料添加剂对产蛋鹌鹑生产性能和蛋品质的影响
T. Măldărășanu, A. Șara, M. Bențea
The research has been carried out on 99 laying quails, randomly distributed in 3 groups, each group consisting of 33 birds. Group 1 received the base diet supplemented with organic Selenium (Sel-Plex) 0.04% + BioMos 0.12%; group 2 received the base diet supplemented with organic Selenium (Sel-Plex) 0.04% + Actigen 0.08, while the control group received the base diet, with no fodder additives. The experimental period was 18 weeks (from 5 weeks to 23 weeks of age). Individual weighing of quails was carried out at the beginning, in the middle and the end of the experimental period. During the experiment, a number of indicators were recorded: body mass evolution, mortality rate, laying intensity, mean egg weight, feed consumption/egg, the weight of the main structural components of eggs and their proportion, egg defects, egg chemical composition and the main physical and morphological indicators of egg quality. The combined use of feed additives (Sel-Plex + Bio-Mos and Sel-Plex + Actigen) led to positive results that confirm the positive influence of these additives, when used in the nutrition of laying quails.
试验选用产蛋鹌鹑99只,随机分为3组,每组33只。1组饲喂基础饲粮,在基础饲粮中添加0.04%的有机硒(self - plex) + 0.12%的BioMos;2组饲喂基础饲粮,在基础饲粮中添加0.04%有机硒(self - plex) + 0.08 Actigen;对照组饲喂基础饲粮,不添加饲料添加剂。试验期18周(5 ~ 23周龄)。分别在试验期开始、中期和结束时对鹌鹑进行个体称重。试验期间,记录了体重演变、死亡率、产蛋强度、平均蛋重、采食量/蛋、蛋主要结构成分重量及其比例、蛋缺陷、蛋化学成分及蛋品质的主要物理形态学指标。饲料添加剂(self - plex + Bio-Mos和self - plex + Actigen)的组合使用取得了积极的结果,证实了这些添加剂在产蛋鹌鹑营养中的积极影响。

Different Fertilization Systems in the Petrova Ecosystem, Maramureș County. Note 1: The Evolution of Forage Production 马拉穆鲁奇县佩特洛娃生态系统的不同施肥系统。注1:牧草生产的演变
Doru Criste, G. Mihai, N. Sima, A. Botis, Iulia Medrea, Bogdan Fagadar
Set on a Festuca rubra - Agrostis capillaris (Agrostis tenuis) grassland, at a height of 628 m in the MaramureE™ Depression, the experiment was carried out by means of the randomized blocks method. We performed a bifactorial experiment with factor A as the amendment, and factor B the level of fertilization.As a result of fertilization throughout the study period using different doses in accordance with the experiment protocol, improvements were observed from one year to the next. The yield grew significantly on the fertilized variants compared to the witness lots, as seen in the dry matter content. The best results were obtained in the organic-mineral fertilized variants.Keeping in mind resource preservation, environment protection and biodiversity conservation, a good strategy regarding these ecological and economic concerns is the use of organic fertilizers on permanent grasslands. Concerning yield growth, the most effective method is the use of mineral and organic-mineral fertilization.The paper presents the evolution in time of the annual forage production, while data about the floristic composition will be presented in a future paper.
在MaramureE™坳陷海拔628 m的红羊茅-毛毛Agrostis (Agrostis tenuis)草地上,采用随机分组法进行实验。以因子a为修正剂,因子B为施肥水平,进行了双因子试验。由于在整个研究期间按照实验方案使用不同剂量的施肥,每年都观察到改善。从干物质含量可以看出,与见证批次相比,受精变异的产量显著增加。以有机矿混合施肥的品种效果最好。考虑到资源保护、环境保护和生物多样性保护,对于这些生态和经济问题,一个好的策略是在永久性草地上使用有机肥。就产量增长而言,最有效的方法是使用矿物和有机矿物施肥。本文介绍了牧草年产量的时间演变,而植物区系组成的数据将在以后的文章中介绍。

Characterization of traditionally obtained buffalo cheese. 传统获得的水牛奶酪的特性。
A. Coroian, C. Coroian, V. Mireșan, C. Răducu, Luisa Andronie, D. Cocan, Z. Marchiș, O. Negrea
In the past decades buffalo milk has attracted growing interest in most countries, especially due to its nutrition characteristics. In Romania, buffalo milk and milk products are mainly considered local and traditional resources, and play an important role in enhancing livestock biodiversity. Currently, the overall availability of milk from all dairy animal species, as well as the possibility of obtaining new products must be analysed. Buffalo milk composition is influenced by season. Milk fat level in autumn is 7.95%, and in the summer it is 7.29%. The highest mean values for the cheese were recorded in the spring season, with a fat and protein content of 41.02% and 21.34%, respectively. In autumn, the fat content is at 36.92%, and protein is at 19.81% . Â
在过去的几十年里,水牛奶在大多数国家引起了越来越多的兴趣,特别是由于它的营养特性。在罗马尼亚,水牛奶和奶制品主要被视为当地和传统资源,在提高牲畜生物多样性方面发挥着重要作用。目前,必须对所有奶牛种类的牛奶的总体可用性以及获得新产品的可能性进行分析。水牛奶的成分受季节的影响。秋季和夏季乳脂含量分别为7.95%和7.29%。奶酪的平均值在春季最高,脂肪和蛋白质含量分别为41.02%和21.34%。秋季脂肪含量为36.92%,蛋白质含量为19.81%。一个

Insects as an alternative protein source for animal feeding: a short review about chemical composition. 昆虫作为动物饲料的替代蛋白质来源:化学成分综述。
V. Vrabec, M. Kulma, D. Cocan
Currently, insects are considered as a potential substitute for fishmeal and Currently, insects are considered as a potential substitute for fishmeal and soybean meal in feeding mixtures for farm animals. However, detailed information regarding insects’ nutritional values is available only for some species. We suggested criteria for insect suitability to mass production and found 15 species from 5 orders which meet our requirements: Blattaria: Blaptica dubia, Blatta lateralis, Eublaberus distanti, Coleoptera: Alphitobius diaperinus, Tenebrio molitor, Zophobas morio, Diptera: Hermetia illucens, Musca domestica, Lepidoptera: Antheraea assamensis, Bombyx mori, Galleria mellonela, Samia riciini, Orthoptera: Acheta domestica, Locusta migratoria, Zonocerus variegates. We have collected available information about their nutritional composition and compared it to soybean meal and fishmeal. Protein content was found to be similar to (or slightly higher than in) soybean and fish meals. In terms of protein quality, it was found that insect protein composition is more similar to soybean protein or fishmeal with low protein concentration, than to that of high concentration fishmeal or casein. Due to highest lysine and metionin contents, we recommend Musca domestica and Samia riciini as most suitable protein sources for poultry and pigs feeding
目前,昆虫被认为是鱼粉的潜在替代品andÂ目前,昆虫被认为是农场动物混合饲料中鱼粉和豆粕的潜在替代品。然而,有关昆虫€™营养价值的详细信息仅适用于某些物种。我们提出了适合大规模生产的昆虫标准,并从5目中找到了15种昆虫,分别是:黑盲蝽、侧盲蝽、远盲蝽、鞘翅目:双翅目:黑盲蝽、黄粉虫、狐盲蝽、双翅目:黑盲蝽、家蝇、鳞翅目:阿萨马蝇、家蚕、黑蝇、黑蝇、直翅目:家蝇、迁徙蝗、杂交虫。我们收集了有关其营养成分的现有信息,并将其与豆粕和鱼粉进行了比较。蛋白质含量与豆粕和鱼粉相似(或略高于)。在蛋白质品质方面,发现昆虫的蛋白质组成与低蛋白质浓度的大豆蛋白或鱼粉更接近,而与高浓度的鱼粉或酪蛋白更接近。由于赖氨酸和提宁含量最高,我们推荐家蝇和里氏萨米蝇作为家禽和猪饲料中最合适的蛋白质来源
