Authors: Wysocki Hubert
Published: December 2017

In this paper, there has been constructed such a model of a non-classical Bittner operational calculus, in which the derivative is understood as a forward difference Δn{x(k)}:={x(k+n)-x(k)}. Next, considering the operation Δn,b{x(k)}:={x(k+n)-bx(k)}, the presented model has been generalized.
Perspective in optimization of stem cell therapies for heart regeneration
Authors: Gapska Paulina , Kurpisz Maciej
Published: December 2017

There is a variety of mechanisms(s) factor(s) that may influence stem cell therapies for heart regeneration. Among the best candidates for stem cell source are: mesenchymal stem cells (also those isolated from adipose tissue), cardiac cell progenitors (CPC) and descendants of iPSC cells. iPSC/s can be potentially beneficial although their pluripotent induction has been still in question due to: low propagation efficacy, danger of genomic integration/instability, biological risk of current vector system teratoma formation etc. which have been discussed in this review. Optimization protocols are required in order to enhance stem cells resistance to pathological conditions that they may encounter in pathological organ and to increase their retention. Combination between gene transfer and stem cell therapy is now more often used in pre-clinical studies with the prospect of subsequent clinical trials. Complementary substances have been contemplated to support stem cell viability (mainly anti-inflammatory and anti- apoptotic agents), which have been tested in animal models with promising results. Integration of nanotechnology both for efficient stem cell imaging as well as with the aim to provide cell supporting scaffolds seem to be inevitable for further development of cellular therapies. The whole organ (heart) reconstruction as well as biodegradable scaffolds and scaffold-free cell sheets have been also outlined.

Authors: Ćota Josip , Hadžić Azra
Published: December 2017

A two-year experiment (2009-2010) included four potato varieties (Desire, Romano, Bistra and Kis Sora). Experiments were conducted in Butmir (about 500 m/ asl) and Glamoč (approximately 900 m/ asl) region. The aim was to select new varieties for our area of cultivation. Productive characteristics of potato varieties (yield, weight and number of tubers per box) were examined. In the frame of qualitative properties, dry matter content and starch were examined. Trials were performed by randomised block design with four replications, and the results were analysed using the analysis of variance. Higher average yield was achieved by Romano cultivar by 8% compared to Desire and Kis Sora. Dry matter content ranged from 21.80% in Romano to 22.20% in Desiree. Examining varieties should be continued in the upcoming period in order to determine the most favourable conditions for cultivation in the area of Bosnia and Herzegovina.

Authors: Putnik-Delić Marina , Maksimović Ivana , Zeremski Tijana , Marjanović-Jeromela Ana
Published: December 2017

Camelina (Camelina sativa L.) is studied mostly as oil plant that can replace oilseed rape in the extensive agriculture. It is a good source of oil (40% oil in seeds) similar to sunflower, soybeans, canola, castor been and other oil crops. Oil of camelina is rich in essential omega 3 fatty acids. In addition, seed protein content is relatively high. Camelina has modest requirements for agro-ecological conditions and it is highly resistant to pathogens. Those features make camelina suitable for human nutrition and animal feed. Its use is related to sustainable agriculture, bio-diesel industry, cold-pressed oils and the use of so-called marginal land. Examination of its ability to uptake and accumulate heavy metals (HM) is interesting from the standpoint of 1) food safety and 2) potential for phytoremediation. Hence, the aim of this study was to investigate the effect of HM on uptake and accumulation of some essential macro- and micronutrients and unwanted HM. Experiments were done with Camelina sativa L., cultivar Stepski 1. The seeds were exposed to 1 µM Cd or Cu and 10 µM Ni or Zn since the beginning of germination. Plants were grown in water cultures, in semi-controlled conditions of a greenhouse, on ½ strength Hoagland solution to which were added HM in the same concentrations as during germination. Concentrations and distribution of Ca, Mg, P, K, Fe and Mn in roots and shoots were altered in the presence of increased concentration of Cd, Cu, Ni and Zn.
Crop Diversification Affects Biological Pest Control
Authors: Marković Dimitrije
Published: December 2017

Crop monocultures encourage the multiplication and spread of pest insects on massive and uniform crop. Numerous studies have evaluated the impact of plant diversification on pests and beneficial arthropods population dynamics in agricultural ecosystems and provided some evidence that habitat manipulation techniques like intercropping can significantly influence pest control. This paper describes various potential options of habitat management and design that enhance ecological role of biodiversity in agroecosystems. The focus of this review is the application and mechanisms of biodiversity in agricultural systems to enhance pest management.

Published: December 2017

Growing field pea for grain and forage is an integral part of the livestock development strategy, due to its importance as a good source of protein in improving milk and meat production. This is of particular relevance to livestock producers in Central Serbia who experience problems in alfalfa production on acidic soils. As a legume, field pea also plays a valuable role in crop rotations. More recently, field pea has been used as an important crop in organic and sustainable farming systems. Under non-irrigated conditions, grain yield of spring pea cvs. ‘NS-Junior’ and ‘Javor’ was evaluated in 2011 and 2012 on an acidic soil receiving amendment applications. A field trial was established in Čačak (43°54'39.06" N, 20°19'10.21" E, 246 m a.s.l.) on an alluvial soil acid in reaction (pHH2O 4.8). The experimental field was fertilized with 300 kg ha-1 N15P15K15. The treatments used included an unfertilized control and liming at 3t ha-1 and 6t ha-1. The experiment was laid out in a completely randomized block design with four replications. Plot size was 5m2 (1x5m). In both years, the average grain yield of cv. ‘NS-Javor’ was significantly higher than in cv. ‘Junior’. No significant differences were observed between the control and the lime treatments.  Grain yield in both years was significantly below the genetic potential of the cultivars tested, mostly due to deficient rainfall and severe soil and air drought conditions.

Authors: Despotović Aleksandra , Joksimović Miljan , Jovanović Miomir
Published: December 2017

Agricultural production in Montenegro has a long tradition and due to available natural resources it could present a backbone of economic development. Almost the entire agricultural production in Montenegro is con­ducted at family holdings. According to the most recent agricultural census from 2010, the total number of agricultural holdings is 48,847, whereof 48,824 are family agricultural holdings or 99%, whilst only 46 companies perform agricultural activities. Regarding the number of hol­dings, the lowest number is in Tivat, 169, whilst Podgorica has the pri­macy with 7,254 holdings. The paper displays the analysis of socio-demo­graphic and agrarian factors at family agricultural holdings. Demo­graphic picture of Montenegrin agricultural population is unfavorable, since intensive aging process has many negative implications, which could be expected in the future period, too.

Published: December 2017

Savings are essential for protecting and boosting the assets of rural populations. The paper analyses rural households’ saving strategies in eastern Bosnia. It is based on a secondary data and primary information collected by a questionnaire survey carried out in March 2013 with 147 rural households from nine municipalities in eastern Bosnia. The questionnaire focused on saving purposes; access to various saving means, including formal and semi-formal ones; membership in and management of saving/credit groups; and reasons for using formal money deposits (banks). The formal and semiformal sectors are currently not meeting the demand for financial services of all rural households. Survey results showed that 72.8% of respondents prefer keeping their savings as cash at home. Savings are also kept in form of livestock, precious metals and jewellery or invested in buildings. Access of rural households to appropriate saving services is of paramount importance for rural livelihood diversification in Bosnia.

Published: December 2017

This research was aimed at investigating polyphenolic content, antioxidant and anti-neurodegenerative activities of post-distillation waste extracts of Macedonian Salvia amplexicaulis, S. jurisicii and S. ringens, for the first time. Total phenolic and flavonoid contents varied in a broad range (3.92-146.49 mg GAE/g and 7.11-67.51 mg QE/g, respectively), with the highest values obtained for S. amplexicaulis and S. ringens extracts. Certain S. amplexicaulis and S. ringens extracts neutralized more than 80% of DPPH radicals at the highest concentration, while S. amplexicaulis extracts showed up to ≈50% inhibition of β-carotene oxidation in β-carotene/linoleic acid assay. Post-distillation waste extracts inhibited acetylcholinesterase (25.94-38.15%) and tyrosinase (18.84-59.52%), with the strongest inhibition of S. amplexicaulis extracts. The obtained results suggest that post-distillation waste of tested species, especially of S. amplexicaulis, show antioxidant and anti-neurodegenerative activities and could be considered as potential raw material rich in polyphenols.

Analiza performansi primarne poljoprivredne proizvodnje i prehrambene industrije Srbije
Authors: Mihailović Branko , Cvijanović Drago , Paraušić Vesna
Published: December 2017

Poljoprivreda je jedan od stubova ekonomskog razvoja Republike Srbije, a njen značaj za nacionalnu ekonomiju, pored ekonomske ima i socijalnu i ekološku komponentu. Međutim, pored velikog potencijala u sektoru poljoprivredne proizvodnje koji je rezultat povoljnih klimatskih uslova, prirodnih karakteristika zemljišta i raspoloživih vodnih resursa, on nije optimalno iskorišćen. Upravo zbog ovakvog potencijala poljoprivreda u Srbiji ne predstavlja običnu privrednu granu, budući da je u svim opštinskim ili regionalnim strategijama definisana kao jedan od strateških pravaca razvoja. Međutim, uspešno uključivanje u međunarodno tržište ograničava nedovoljan asortiman prehrambenih proizvoda u odnosu na aktuelnu ponudu u razvijenom svetu, pri čemu je zapostavljeno istraživanje za veće iskorišćenje postojećih kapaciteta kroz uvođenja novih linija i proizvoda. Kao ograničavajući faktor ističe se osciliranje kvaliteta tržišnih proizvoda kako zbog nepostojanja standarda tako i zbog nepoštovanja i nedovoljne kontrole postojećih standarda. Takođe, sporo je prilagođavanje tržišnim kriterijumima poslovanja koji se baziraju na uvođenju savremenih sistema menadžmenta i marketinga. Nedovoljna predvidivost u poslovanju prehrambene industrije uslovljena je nepostojanjem dugoročnih ugovornih odnosa između prehrambene industrije i proizvođača sirovina, kao i nepostojanjem tržišne integrisanosti, primarne poljoprivredne proizvodnje i industrije koja za svoj input koristi upravo poljoprivredne proizvode.
Evidencija, procena, kvantifikacija i analiza poslovanja porodičnih poljoprivrednih gazdinstava
Authors: Ceranić Slobodan , Paunović Tamara , Novković Nebojša
Published: December 2017

Kada je u pitanju poljoprivredna proizvodnja Srbije, onda se porodična poljoprivredna gazdinstva mogu smatrati osnovnim subjektom. Svojim nastojanjima da se priključi Evropskoj uniju, Srbija je jasno stavila do znanja da na tom putu agrarni sektor mora da doživi korenite promene. Naime, taj put će biti dosta težak, jer se pred nas postavlja zadatak sprovođenja organizaciono-ekonomskih mera u cilju usklađivanja sa standardima sa EU. Posebno složena situacija je na gazdinstvima u oblasti evidencije i analize poslovanja poljoprivrednih gazdinstava. Ovakva situacija dovodi vlasnike u dosta nepovoljan položaj, jer nisu u stanju da kvantifikuju ulaganja a ni ostvarene rezultate. Situacija se posebno komplikuje kada porodična poljoprivredna gazdinstva zatraže novčana sredstva, po bilo kom osnovu. Tada davaoci sredstava skoro da nemaju nikakvu predstavu o rezultatima poslovanja gazdinstva, njegovoj ekonomskoj moći i perspektivama. Bilo kakav sistem evidencije na porodičnim gazdinstvima ovu situaciju bi poboljšao u značajnoj meri.
Генотипске специфичнсти приноса конзумних кртола кромпира
Authors: Ћота Јoсип , Дардић Миле , Шиљ Милана
Published: December 2017

О значају кромпира као гајеног усјева писано је много. Кромпир представља основу исхране становништва у многим земљама свијета. По истраживањима Међународног центра за кромпир (CIP), ова врста се сматра четвртим најважнијим свјетским гајеним усјевом. Без обзира на дужину периода од када је постао гајени усјев, начин производње, традицију и навику у потрошњи и потрошњу “per capita”, он  данас представља изузетно значајну гајену биљку. У БиХ садне површине под кромпиром варирају и  крећу се од 41000-50000 ha од чега у Републици Српској око 18500-20500 ha и Федерацији БиХ око 22500-26000 ha. Без обзира што је само млади кромпир повртни усјев, а сав остали ратарски усјев,  од укупних обрадивих површина Републике кромпиру припада 7,6%,  а  осталом поврћу 7,8%. Према обиму годишње производње од просјечно 480000 t и варјабилном приносу од 9-12 t/ha, по значају је други гајени усјев у Републици, послије кукуруза, а испред пшенице. Промјенљиви и различити еколошки услови, слаба техничка опремљеност и технолошка (стручна) оспособљеност произвођача представљена просјечно, за европске размјере, ниским приносом, намећу потребу сталног трагања за новим производним рјешењима. Једноставан, а добар покушај јесте нова сорта, односно генотип, али ни она  са сигурношћу не рјешава производни успјех. Ипак је вишегодишње производно тестирање нових сорти високог генетичког потенцијала родности у различитим еколошким (климатским и земљишним) условима преко оствареног приноса  полазна основа избора новог генотипа и његовог увођења у производњу, његове адаптабилности на промјенљиве услове средине и најчешћи  начин ка остварењу производног успјеха узгајивача.  У раду су представљена четворогодишња  истраживања приноса конзумне фракције кртоле кромпира код три  генотипа високог потенцијала родности у еколошки различитим условима, Сарајевско поље (Бутмир) и Гламоч. Резултати истраживања су показали да принос као сложено  својсво  најзначајније варира по годинама, затим, мање по локалитету, а најмање по генотипу.

Published: December 2017

U ovom radu prikazani su rezultati merenja temerature nadzemnog dela biljaka paprike i paradajza primenom termovizijske kamere sa ciljem određivanja uticaja mulč folije na temperaturu biljnog pokrivača. Ogled je postavljen na otvorenom polju na zemljištu tipa karbonatni černozem u Staroj Pazovi (40 km severno od Beograda, Srbija), a merenja temperature  izvedena u periodu maj-septembar 2012. Kod paprike su praćene tri varijante režima navodnjavanja sa i bez mulč folije. Varijanta sa punim navodnjavanjem (F) kada je pokriveno 100 % ETc (evapotranspiracije kulture), varijanta sa redukovanim navodnjavanjem (R) kada je pokriveno 80% ETc i varijanta sa redukovanim navodnjavanjem (S) kada je pokriveno 70% ETc. Kod paradajza su praćene dve varijante režima zalivanja, varijanta sa punim navodnjavanjem, (F) kada je pokriveno 100 % ETc i varijanta sa redukovanim navodnjavanjem (S) kada je pokriveno 50% ETc sa i bez primene mulč folije. Merenja temperature biljaka izvedena su termovizijskom kamerom (FLIR, T335) četiri puta u toku vegetacije paprike i šest puta u toku vegetacije paradajza. Sa svake varijante je uzet uzorak od 15 temperatura na osnovu kojih je merena prosečna temperatura biljaka na svakoj varijanti navodnjavanja. Podaci merenja temperatura nadzemnog dela paprike pokazuju, da je temperatura biljnog pokrivača bila niža na svim varijantama gde je postavljena mulč folija. Biljke paprike na F, R, S varijantama sa mulč folijom bile su hladnije od biljaka na istim varijantama zalivanja bez mulč folije prosečno za 1.45°C, 1.52°C, 1.38°C, respektivno. Kod paradajza razlike su manje u odnosu na papriku. Na F varijanti sa mulč folijom biljke su bile  prosečno za 0.3 °C hladnije od biljaka na F varijanti bez folije. Na varijanti redukovanog zalivanja (S), temperatura biljaka paradajza sa mulč folijom je prosečno za 1°C niža od temperature biljaka bez folije. Rezultati merenja pokazuju da  postoji značajan uticaj mulč folije na temperaturu biljnog pokrivača paprike, a u manjoj meri kod paradajza. Mulč folija umanjuje evaporaciju, biljke imaju na raspolaganju više vode, intenzivnija je transpiracija, pa je zagrevanje biljke manje. Paradajz je biljka gušćeg sklopa kod koje razvijena  biomasa utiče na smanjenje  evaporacije u odnosu na otkriveno zemljište,  pa je uticaj folije manje izražen.

Циљ рада је да укаже на значај салаша за развој туристичке понуде Војводине и то, пре свега, за развој руралног туризма. Салаши представљају аутентичан приказ некадашњег начина живота и рада војвођанских паора. Према историјским подацима подизање салаша на подручју данашње Војводине започело је половином 18.века, највише их је било између Првог и  Другог светског рата. Данас се не зна њихов тачан број, али је евидентно  да их има много мање. Од преосталих салаша многи су претворени у праве туристичке оазе. У циљу афирмације туристичке понуде салашарског, као посебног облика руралног туризма, у раду ће бити представљени аутентични војвођански салаши: Мајкин и Цветни салаш на Палићу, Цвејин код Бегеча, Бабин близу Зрењанина,  као и Дида Хорњаков салаш у околини Сомбора, али и други салаши који су своју понуду  прилагодили савременом туристи.
Mogućnosti za proizvodnju biomase na livadama i pašnjacima kao faktor unapređenja ovčarske proizvodnje u Srbiji
Authors: Arsić Slavica , Jovanović Marijana
Published: December 2017

Proizvodnja kvalitetne sveže stočne hrane predstavlja važnu komponentu u stočarskoj proizvodnji. Kao takva je od strateškog značaja za stvaranje stabilnosti i oporavak stočarstva, naročito u planiniskim područjima Republike Srbije. Na teritoriji naše zemlje učešće livada i pašnjaka u strukturi zasejanih površina je zadovoljavajuće, dok je proizvodnja krmnog bilja zastupljena sa 9,1% površina. Shodno tome, mogućnosti za ishranu ovaca je pozitivan, čime se može smanjiti upotreba koncentrovanih hraniva i poboljšati kvalitet krajnjih proizvoda (mleka, mesa i vune). Radom je istaknuta geografska zastupljenost ovčarske proizvodnje po Regionima i njihovog udela u ukupnoj proizvodnji, kao i procentualna podela proizvodnje na prirodnim livadama i pašnjacima, čime se jasno stavlja na uvid stručne i naučne javnosti trenutno stanje, a daju i preporuke za buduće jačanje ovčarske proizvodnje u Republici Srbiji.

Published: December 2017

Endemična vrsta Telestes metohiensis (gatačka gaovica) naseljava veći broj vodotoka Istočne Hercegovine i sve tekućice u Dabarskom polju. U poslednjim decenijama u značajnoj mjeri su promjenjeni uslovi u većini staništa ove vrste. Vodotoci Dabarskog polja se međusobno razlikuju po kvalitetu životnih uslova, kako sa fizičko-hemijskog tako i sa mikrobiološkog aspekta. Neki vodotoci su aktivni čitave godine, sa manjim ili većim proticajima, dok su neki privremenog karaktera. U radu su predstavljene vrijednosti osnovnih morfometrijskih karakteristika: totalne i standardne dužine, kao i masa i Fultonov koeficijent uhranjenosti kod gaovica iz tri vodotoka Dabarskog polja (Vrijeka, Opačica, Pribitul). Relevantnim statističkim metodama izvršena je obrada dobijenih podataka i komparacija praćenih karakteristika kod jedinki iz različitih vodotoka.

У раду је анализирана ефикасност хемијске заштите засада јабуке примјеном класичног атомизeра са усмјеривачима. Циљ анализе је био да утврди предности апликације баждареним, контролисаним и прецизно подешеним атомизером у односу на класичну заштиту. Под појмом класичне заштите подразумијева се експлоатација атомизера без праћења исправности и подешености основних параметара (проток пумпе, исправност манометра, исправност распрскивача, подешеност количине ваздушне струје вентилатора, исправност мјешача итд.). Предности апликације баждареним атомизером су вишеструке, а огледају се прије свега у уштеди препарата, смањењу утрошка људског и машинског рада, а битан је и еколошки аспекат. Еколошки аспекат се прати у виду губитака пестицидне течности у облику земљишног дрифта. Помоћу водосензитивних плочица мјерени су губици радне течности на земљишту, упоређујући баждарени и небаждарени атомизер. Препоручена норма при испитивању износила је 500 l/ha, међутим приликом мјерења евидентирана је норма од 754 l/ha, тј. увећана за  50,80%. Разлог увећања је неисправан манометар и лоша дистрибуција распрскивача. Након калибрације и подешавања постигнута је норма од 422 l/ha, односно умањена за 55,96%  у односу на затечену. Примјена баждареног и прецизно подешеног атомизера обезбиједила је смањење норме третирања за 15,60% од препоручене, уз добру покривеност круне. Предност примјене калибрисаног и прецизно подешеног атoмизера огледа се у смањењу дрифта, а кроз умањење дрифта и побољшање еколошког ефекта. Резултати истраживања показују да се правилном калибрацијом земљишни дрифт може смањити на минималне количине. Ако се узме у обзир просјечна цијена заштите од 350 KM/ha укључујући цијену пестицида, људски и машински рад, имамо случај да економска анализа третирања јабуке показује да контролисана апликација умањује цијену заштите по једном третирању у просјеку око 55 KM/ha. Пројектовано на цијелу сезону, уштеде при заштити износе око 1100 KM/ha  ако узмемо у обзир да је просјечан број третирања око 20 пута, у зависности од сезоне до сезоне.

Large quantities of biomass result from fruit pruning, which is a re­quired pomotechnical operation. Long-standing practice of destroying and burning the pruning residues is hard to change, although energy and envi­ronmental indicators point to the importance of the proper biomass exploitation. The aim of this study is to show the quantity and energy value of pruning residues from apple production, as well as ways and means of their proper exploitation. In Republicof Serbia, apple is grown at 40,000 ha, with the usual biomass yield (3 t ha-1 pruning residues). Upper heating value of pruning residues for two apple varieties (Idared and Jonagold), with 42.36% moisture, was 18.14 MJ kg-1 average.

Published: December 2017

As natural water supply rarely meets crop water requirements, irrigation has a great role in yield assurance in quantity and quantity. Irrigation could be economically justified if water use efficiency (WUE) is fulfilled. Therefore, the aim of this work was to determine WUE of irrigated and rainfed crops grown in Serbia. The analysis of crop water consumption and obtained yield was based on data collected from various scientific publications. Irrigation effect differed by years, but not strictly due to rainfall amount and occurrence. The yield of some crops strongly depends on available soil moisture such as alfalfa, fodder sorghum, maize and soybean with clear relationship, whereas of some crops such relation cannot be found. It indicates that WUE also depends on some other factors, such as extreme temperatures, frost, hail, nutrient supply and plant health, as well.

Published: December 2017

Given that strawberries are very short-lived and easily perishable, extending their shelf life would be very cost effective. Strawberries of the Arosa cultivar were treated with various concentrations of 1-methyl­cyclopropene (0.050, 0.100, 0.500 ppm) in order to determine the optimal concentration for extending their storage life. Two different treatment conditions were used: treatment for 2 h at 20°C and treatment for 20h at 4°C. Total phenols content, total anthocyanins, total soluble solids, fruit firmness, titratable acidity, pH and weght loss were monitored for 11 days of storage in the cold room at 3oC. The best results were achieved by treatment with 0.1 ppm 1-methylcyclopropene for 2 h at 20°C.

Background

An increasingly large share of diet comes from ultra-processed foods (UPFs), which are assemblages of food substances designed to create durable, convenient and palatable ready-to-eat products. There is increasing evidence that high UPF consumption is indicative of poor diet and is associated with obesity and metabolic disorders. This study sought to examine the relationship between percent of energy intake from ultra-processed foods (PEI-UPF) during pregnancy and maternal gestational weight gain, maternal lipids and glycemia, and neonatal body composition. We also compared the PEI-UPF indicator against the US government’s Healthy Eating Index-2010 (HEI-2010).

Methods

Data were used from a longitudinal study performed in 2013–2014 at the Women’s Health Center and Obstetrics & Gynecology Clinic in St. Louis, MO, USA. Subjects were pregnant women in the normal and obese weight ranges, as well as their newborns (n = 45). PEI-UPF and the Healthy Eating Index-2010 (HEI-2010) were calculated for each subject from a one-month food frequency questionnaire (FFQ). Multiple regression (ANCOVA-like) analysis was used to analyze the relationship between PEI-UPF or HEI-2010 and various clinical outcomes. The ability of these dietary indices to predict clinical outcomes was also compared with the predictive abilities of total energy intake and total fat intake.

Results

An average of 54.4 ± 13.2% of energy intake was derived from UPFs. A 1%-point increase in PEI-UPF was associated with a 1.33 kg increase in gestational weight gain (p = 0.016). Similarly, a 1%-point increase in PEI-UPF was associated with a 0.22 mm increase in thigh skinfold (p = 0.045), 0.14 mm in subscapular skinfold (p = 0.026), and 0.62 percentage points of total body adiposity (p = 0.037) in the neonate.

Discussion

PEI-UPF (percent of energy intake from ultra-processed foods) was associated with and may be a useful predictor of increased gestational weight gain and neonatal body fat. PEI-UPF was a better predictor of all tested outcomes than either total energy or fat intake, and a better predictor of the three infant body fat measures than HEI-2010. UPF consumption should be limited during pregnancy and diet quality should be maximized in order to improve maternal and neonatal health.
TGF‐β transactivates EGFR and facilitates breast cancer migration and invasion through canonical Smad3 and ERK/Sp1 signaling pathways

Published: December 2017

Transforming growth factor‐beta (TGF‐β) functions as a potent proliferation inhibitor and apoptosis inducer in the early stages of breast cancer, yet promotes cancer aggressiveness in the advanced stages. The dual effect of TGF‐β on cancer development is known as TGF‐β paradox, and the remarkable functional conversion of TGF‐β is a pivotal and controversial phenomenon that has been widely investigated for decades. This phenomenon may be attributed to the cross talk between TGF‐β signaling and other pathways, including EGF receptor (EGFR) signaling during cancer progression. However, the underlying mechanism by which TGF‐β shifts its role from a tumor suppressor to a cancer promoter remains elusive. In this study, TGF‐β is positively correlated with EGFR expression in breast cancer tissues, and a functional linkage is observed between TGF‐β signaling and EGFR transactivation in breast cancer cell lines. TGF‐β promotes the migration and invasion abilities of breast cancer cells, along with the increase in EGFR expression. EGFR is also essential for TGF‐β‐induced enhancement of these abilities of breast cancer cells. Canonical Smad3 signaling and ERK/Sp1 signaling pathways mediate TGF‐β‐induced EGFR upregulation. Hence, our study provided insights into a novel mechanism by which TGF‐β supports breast cancer progression.
Influence of Slope‐Scale Snowmelt on Catchment Response Simulated With the Alpine3D Model
Authors: Brauchli Tristan , Trujillo Ernesto , Huwald Hendrik , Lehning Michael
Published: December 2017

Snow and hydrological modeling in alpine environments remains challenging because of the complexity of the processes affecting the mass and energy balance. This study examines the influence of snowmelt on the hydrological response of a high‐alpine catchment of 43.2 km2 in the Swiss Alps during the water year 2014–2015. Based on recent advances in Alpine3D, we examine how snow distributions and liquid water transport within the snowpack influence runoff dynamics. By combining these results with multiscale observations (snow lysimeter, distributed snow depths, and streamflow), we demonstrate the added value of a more realistic snow distribution at the onset of melt season. At the site scale, snowpack runoff is well simulated when the mass balance errors are corrected (R2 = 0.95 versus R2 = 0.61). At the subbasin scale, a more heterogeneous snowpack leads to a more rapid runoff pulse originating in the shallower areas while an extended melting period (by a month) is caused by snowmelt from deeper areas. This is a marked improvement over results obtained using a traditional precipitation interpolation method. Hydrological response is also improved by the more realistic snowpack (NSE of 0.85 versus 0.74), even though calibration processes smoothen out the differences. The added value of a more complex liquid water transport scheme is obvious at the site scale but decreases at larger scales. Our results highlight not only the importance but also the difficulty of getting a realistic snowpack distribution even in a well‐instrumented area and present a model validation from multiscale experimental data sets.
Colossal X‐Ray‐Induced Persistent Photoconductivity in Current‐Perpendicular‐to‐Plane Ferroelectric/Semiconductor Junctions

Persistent photoconductivity (PPC) is an intriguing physical phenomenon, where electric conduction is retained after the termination of electromagnetic radiation, which makes it appealing for applications in a wide range of optoelectronic devices. So far, PPC has been observed in bulk materials and thin‐film structures, where the current flows in the plane, limiting the magnitude of the effect. Here using epitaxial Nb:SrTiO3/Sm0.1Bi0.9FeO3/Pt junctions with a current‐perpendicular‐to‐plane geometry, a colossal X‐ray‐induced PPC (XPPC) is achieved with a magnitude of six orders. This PPC persists for days with negligible decay. Furthermore, the pristine insulating state could be fully recovered by thermal annealing for a few minutes. Based on the electric transport and microstructure analysis, this colossal XPPC effect is attributed to the X‐ray‐induced formation and ionization of oxygen vacancies, which drives nonvolatile modification of atomic configurations and results in the reduction of interfacial Schottky barriers. This mechanism differs from the conventional mechanism of photon‐enhanced carrier density/mobility in the current‐in‐plane structures. With their persistent nature, such ferroelectric/semiconductor heterojunctions open a new route toward X‐ray sensing and imaging applications.

Titanium plates are widely used in clinical settings because of their high bone affinity. However, owing to their high elastic modulus, these plates are not suitable for bone repair since their proximity to the bone surface for prolonged periods can cause stress shielding, leading to bone embrittlement. In contrast, titanium fiber plates prepared by molding titanium fibers into plates by simultaneously applying compression and shear stress at normal room temperature can have an elastic modulus similar to that of bone cortex, and stress shielding will not occur even when the plate lies flush against the bone's surface. Titanium fibers can form a porous structure suitable for cell adhesion and as a bone repair scaffold. A titanium fiber plate is combined with osteoblasts and shown that the titanium fiber plate is better able to facilitate bone tissue repair than the conventional titanium plate when implanted in rat bone defects. Capable of being used in close contact with bone for a long time, and even capable of promoting bone repair, titanium fiber plates have a wide range of applications, and are expected to make great contributions to clinical management of increasing bone diseases, including bone fracture repair and bone regenerative medicine.

Plasmonic dipoles are famous for their strong absorptivity rather than their reflectivity. Here, the as‐yet unknown specular reflection and the Brewster effect of ultrafine plasmonic dipoles, metaparticles, are introduced and exploited as the basis of new design rules for advanced applications. A configuration of “Plasmonic metaparticles on a blackbody” is demonstrated and utilized for the design of a tailored perfect‐colored absorber and for visual detection of environmental dielectrics that is not readily done by extinction plasmonics. Moreover, the Plasmonic Brewster Wavelength (PBW) effect is introduced as a new platform for the naked‐eye and bulk biodetection of analytes. The technique operates based on slight changes of molecular polarizability which is not detectable via conventional plasmon resonance techniques. As a specific highlight, the clinical applicability of the PBW method is demonstrated while addressing the transduction plasmonic techniques' challenge in detection of bulk refractive index changes of the healthy and diseased human serum exosomes. Finally, the sputtering‐based fabrication method used here is simple, inexpensive, and scalable, and does not require the sophisticated patterning approach of lithography or precise alignment of light coupling for the biodetection.
