Cilj ovog istraživanja bio je utvrditi ulogu sociodemografskih obilježja, zadovoljstva obitelji i socijalne podrške u problemima u ponašanju djece i mladih. U tu svrhu provedeno je istraživanje na 208 učenika 4-tih razreda osnovne škole prosječne dobi 10,12 godina i 8-ih razreda osnovne škole prosječne dobi 14,14 godina pomoću sljedećih mjernih instrumenata: Skale socijalne podrške, Skale financijske dostupnosti, Skale samoprocjene ponašanja mladih i Skale zadovoljstva obitelji. Rezultati dobiveni istraživanjem vode zaključku da su eksternalizirani problemi u ponašanju češći kod starije djece/mladih koji su ujedno manje zadovoljni obitelji u odnosu na mlađu djecu. U internaliziranim problemima u ponašanju nije zabilježena značajna razlika s obzirom na dob. Razlike s obzirom na spol također nisu zabilježene. Ispitujući korelaciju među internaliziranim problemima ponašanja značajna je povezanost s zadovoljstvom obitelji, financijskom dostupnošću i socijalnom podrškom. Hijerarhijska regresijska analiza pokazuje da zadovoljstvo obitelji i socijalna podrška samostalno objašnjava 31% zajedničke varijance internaliziranih problema u ponašanju kod djece i mladih. Značajni korelati eksternaliziranih problema u ponašanju zadovoljstvo su obitelji i socijalna podrška, a u završnom koraku zadovoljstvo obitelji 18% samostalno doprinosi objašnjenju varijance eksternaliziranih problema u ponašanju kod djece i mladih.
Procjena poljoprivredne pismenosti studenata budućih učitelja primarnog obrazovanja
Authors: Braičić Zdenko
Published: March 2019

U razrednoj se nastavi sadržaji o poljoprivredi uglavnom poučavaju u nastavnom predmetu Priroda i društvo. Kako bi uspješno mogli ostvariti nastavne zadaće, studentima, budućim učiteljima, potrebna je određena baza stručnih znanja o poljoprivredi. Cilj istraživanja bio je procijeniti razinu poljoprivredne pismenosti studenata Učiteljskog fakulteta u Zagrebu te poznavanje sadržaja Prirode i društva o poljoprivredi. Njegova je svrha prepoznati sadržaje o poljoprivredi koje studenti nedovoljno poznaju kako bi se unaprijedili programi pojedinih kolegija i redefinirali ishodi učenja. Utvrđeno je da 38,7% ispitanih studenata ne raspolaže minimalnim znanjima o poljoprivredi, dok njih 22,0% nedovoljno poznaje nastavne sadržaje Prirode i društva o poljoprivredi. U radu se ispituje postojanje razlika u znanju studenata o poljoprivredi i poznavanju nastavnih sadržaja s obzirom na godinu studija, mjesto odrastanja i vrstu završene srednje škole.
Razlikovni kurikulum kao pretpostavka uspješne inkluzije
Authors: Zrilić Smiljana
Published: March 2019

Polazeći od činjenice da obrazovne institucije postaju sjecištima različitih etniciteta, kultura, religija i jezika, da učenici dolaze iz sve različitijih obitelji (jednoroditeljskih, binuklearnih, posvojiteljskih, udomiteljskih), te da su učenici s posebnim potrebama uključeni u redovite odgojno-obrazovne skupine, izazovi budućnosti pojedinca i društva ogledaju se, među ostalim, u ustroju i kvaliteti obrazovnih sustava. Suočena s novim izazovima škola se mijenja u pravcu stvaranja povoljnih uvjeta za razvoj socijalnih, intelektualnih i emocionalnih kapaciteta učenika u skladu s njihovom kronološkom i mentalnom dobi. S tim u svezi neizbježni su zahtjevi na razini metodičke i sadržajne prilagodbe odgojno-obrazovnog procesa, odnosno posebne odgojno-obrazovne podrške različite vrste i razine. Govorimo o prilagođenim, tj. primjerenim programima i modelima učenja uz socijalno kompetentnog učitelja i ostale sudionike uključene u sve segmente odgoja i obrazovanja, izradi i mogućnostima implementacije diferencijalnih programa i razlikovnih kurikuluma. Nove obrazovne potrebe društva i pojedinca iniciraju zahtjev za stvaranjem takvog profila obrazovnih institucija koje predstavljaju stimulativnu sredinu za učenje i razvoj socijalnih odnosa. Mijenjaju se odnosi među ljudima u životnim zajednicama, te otvaraju pitanja dijaloga, suživota, snošljivosti i međusobnog uvažavanja.
Odgoj za dijalog kao preduvjet mira. Kršćanska perspektiva odgoja za dijalog
Authors: Ćavar Klara , Vujica Vikica
Published: March 2019

U članku se govori o ulozi Crkve u odgoju te njenom doprinosu međureligijskom dijalogu odgojem. Prvi dio rada donosi pitanje pristupa Crkve dijalogu, osobito zadnjih pedeset-šezdeset godina. Polazeći od enciklike Pacem in terris pape Ivana XXIII., preko uloge koju je imao Drugi vatikanski koncil u otvaranju Crkve prema svijetu i drugim religijama, pa do današnjeg stava Crkve i uloge koju ima papa Franjo u promicanju mira i dijaloga, autorice predstavljaju opredjeljenje Crkve za dijalog, svjesne da je dijalog – iako se na njemu snažno inzistira – u krizi. Drugi dio rada promišlja pitanje laika i odgoja za dijalog, to jest koju ulogu Crkva daje laicima u odgoju te kako odgajati za dijalog, koji u našem vremenu velikih migracija i globalizacije ima posebnu ulogu. Stoga se govori o dijalogu na „dvije razine“: teološkoj – ili dijalogu stručnjaka – koji ima više podvrsta, te životnom dijalogu – koji se događa u svakodnevici svih ljudi ukoliko su spremni otvoriti se nepoznatom. U ovom drugom tipu dijaloga škola, obrazovanje i odgoj, imaju značajnu ulogu.

S obzirom na to da živimo u društvu znanja, potrebe tržišta rada svaki dan postavljaju nove zahtjeve za kompetencijama. Projektni pristup dizajniranju obrazovanja javlja se kao neminovnost. Kompetencije su ključni faktor i jedan od preduvjeta za uspjeh pojedinca na tržištu rada, koje će u skoroj budućnosti biti još fleksibilnije jer će za 8 godina zahtijevati mnoge nove kompetencije. Sustav obrazovanja mora pripremiti današnjeg učenika za buduće kompetencije temeljene na ZVSSOUP modelu. U ovom radu postavljeni su teorijski elementi dizajniranja i redizajniranja obrazovnih sadržaja po projektnim principima. Efikasan algoritam projektnog modela pretpostavlja projektiranje od finalnog cilja prema početku. Predložen algoritam može zadovoljiti potrebe brzog redefiniranja potrebnih kompetencija za buduće tržište rada, a testirat će se i budućim empirijskim istraživanjem.
Pregled ranoga govorno-jezičnoga razvoja
Authors: Vrsaljko Slavica , Paleka Petra
Published: March 2019

U radu će se dati pregled ranoga govorno-jezičnoga razvoja, od rođenja do 6. godine života, odnosno do polaska u školu. Razvoj govora suptilan je i složen proces te se odvija pod utjecajem različitih čimbenika. Osim toga to je i socijalan fenomen čiji je razvoj moguć isključivo u uvjetima ljudskog okruženja u kojem najveću ulogu ima obitelj. Vrlo je važno znati da dječji razvoj slijedi određene zakonitosti pa je bitno da roditelji to znaju kako bi ih svjesno mogli pratiti te ih poticati. Dijete u prvih pet godina života nauči da se u razgovoru s drugima mora pridržavati nekih pravila: preispitivati svoje iskaze, govoriti kada je njegov red, uspostavljati očni kontakt. Također, mijenja se način govora s obzirom na sugovornika. To su neki od pokazatelja da je dijete ovladalo pravilima društvenoga jezika. Osim ključnih teorijskim postavki ranoga govorno-jezičnog razvoja, u radu će se staviti naglasak i na usvajanju značenja jezičnih elemenata te osnovnih morfoloških struktura (glagola, imenica, pridjeva).

Authors: Demirozu Zumrut T. , Critsinelis Andre , Cohn William E. , Radovancevic Rajko , Ho Jonathan , Hernandez Ruben , Morgan Jeffrey Adam , Frazier O Howard
Published: March 2019

Background: Advanced age is a relative contraindication for heart transplantation, but no age cutoff has been defined for patients receiving mechanical circulatory support.
Methods: Between November 1, 2003 and November 1, 2012, we implanted the HeartMate II (HMII) left ventricular assist device (LVAD) in 319 patients. One hundred seven patients (89 men, 18 women) were over 60 years old (mean, 66 ± 4 years; range, 61-78 years) and received the HMII as a bridge to transplantation (n = 45) or as destination therapy (n = 62). We evaluated their experience by performing a retrospective analysis.
Results: Seventy-two patients had ischemic cardiomyopathy, and 34 had idiopathic cardiomyopathy. Three patients (2.8%) already had a HeartMate XVE LVAD; 54 (50.5%) were receiving intra-aortic balloon pump support; 52 (48.6%) had undergone a previous cardiac procedure; and 9 (8.4%) had received renal replacement therapy (RRT) (continuous venovenous hemofiltration, hemodialysis, or both) before HMII implantation. The median duration of HMII support was 313 days (range, 1-3339 days). After device implantation, 36 patients (33.6%) had gastrointestinal bleeding, 24 (23%) required RRT, 18 (17.5%) had ventricular arrhythmias, and 24 (22.4%) had LVAD-related infections, and 9 (8.4%) had right ventricular failure requiring mechanical support, and 28 (26.2%) had neurologic complications. The actual survival rate was 69% at 6 months, 63% at 1 year, and 54% at 2 years. Eighty-one patients died; 9 are still receiving HMII support; and 17 are alive after heart transplantation.
Conclusions: Older patients can benefit from LVAD therapy, and advanced age should not preclude LVAD implantation.

Published: March 2019

In the past two decades, evidence-based reform in education has been gaining momentum worldwide. China is no exception.  Though many Chinese scholars have acknowledged the importance of evidence-based reform in education, some remain skeptical.  In this paper, we address the three major concerns about evidence-based reform in education and offer some clarifications on the issues raised by critics.
A proof-theoretic approach to scope ambiguity in compositional vector space models
Authors: Wijnholds Gijs
Published: March 2019

We investigate the extent to which compositional vector space models can be used to account for scope ambiguity in quantified sentences (of the form Every man loves some woman). Such sentences introduce one reading for each quantifier. We combine a polarised focussed sequent calculus for the non-associative Lambek Calculus NL as described in Moortgat and Moot (2011) with a non-compositional ap- proach to quantifier scope in vector space semantics introduced by Hedges and Sadrzadeh (2016) and (Sadrzadeh 2016). In particular, we obtain an automatic and compositional procedure for obtaining quantifier scope ambiguity in vector space models of meaning.
A Note on movement in logical grammar
Authors: Morrill Glyn
Published: March 2019

In this article we make remarks on overt and covert movement inlogical grammar. With respect to the latter (e.g. quantification) weobserve how a treatment in terms of displacement calculus interactswith normal modalities for intensionality to allow a coding in logicalgrammar of the distinction between weak and strong quantifiers(i.e. those that may or may not not scope nonlocally such as'a' and 'every' respectively). With respect to overt movement (e.g.relativisation) we observe how displacement calculus supportsa coding of a filler-gap dependency similar to that employed in lambdagrammars, but we argue that this general approach does not extend toparasitic gaps, for which we propose exponentials.

Published: March 2019

RESUMO Dentre as plantas daninhas com comprovada resistência ao glyphosate, destaca-se o capim-amargoso (Digitaria insularis). O objetivo deste trabalho foi demonstrar que a susceptibilidade de diferentes populações de D. insularis ao glyphosate é consequência do histórico de controle químico adotado nas áreas agrícolas. Sete populações de capim-amargoso, provenientes da região produtora de grãos, no sudeste de Goiás (três de Silvânia, duas de Gameleira de Goiás, uma de Pires do Rio e uma de Orizona), foram analisadas por meio da curva dose-resposta. Estudaram-se a susceptibilidade diferencial e a capacidade de rebrota das populações submetidas a diferentes doses de glyphosate (0; 0,11; 0,21; 0,42; 0,84; 1,68; 3,36; 6,72; 13,44 e 26,88 kg ha-1 i.a.). Além disso, elaborou-se um dendrograma de susceptibilidade ao herbicida, por meio da análise de agrupamento hierárquico UPGMA. As populações de capim-amargoso, manejadas há cinco anos com glyphosate associado a herbicidas inibidores da ACCase, são susceptíveis ao glyphosate; quando manejadas de forma intensiva, unicamente com glyphosate, apresentaram-se menos susceptíveis. O mesmo resultado foi observado com a análise de agrupamento, que indicou a formação de dois grupos, o primeiro composto por populações oriundas de Silvânia, Orizona, Pires do Rio, Gameleira de Goiás, consideradas susceptíveis ao glyphosate e, o segundo grupo, composto por populações oriundas de Gameleira de Goiás e Silvânia, as menos susceptíveis. As populações de capim-amargoso menos sensíveis apresentam maior capacidade de rebrota da parte aérea, após tratadas com doses elevadas de glyphosate.

Published: March 2019

ABSTRACT This study had the aim of evaluating 15 agronomic characters of 23 banana genotypes of the Cavendish, Prata, Prata-Anã, Pacovan, Mysore and Maçã groups, in three production cycles, in the climatic conditions of the central region of Goiás state, Brazil, identifying superior cultivars. The treatments were arranged in a completely randomized design, with replicates varying from 3 to 18 clones according to the availability of seedlings. Because of the unbalanced data, the components of variance were estimated using the mixed model methodology. In order to identify the superior genotypes, the predicted mean genotypic values were taken into account. The FHIA-02 (Cavendish group), PA42-44 (Prata Anã group) and FHIA-18 (Prata Anã group) genotypes presented the highest flowering precocity. The Bucanero, FHIA-17 (Cavendish group) and Grande Naine genotypes were the most productive. The Grande Naine, FHIA-17 and FHIA-02 genotypes presented the lowest sizes, and the FHIA-17, Bucanero and PV79-34 (Hybrid Pacovan) genotypes the largest pseudo stems circumferences. The genotypes with the lowest mortality rates were the Pacovan, Garantida (group Prata) and Calipso. Based on the multi-trait selection index, it was concluded that the FHIA-17, Grande Naine, Bucanero, and FHIA-02 genotypes were the most promising cultivars for production in the central region of Goiás due to their agronomic characters and high yield.
Centesimal composition and antioxidant compounds of two fruits from the Cerrado (Brazilian Savannah)
Authors: Lima Maria Carolina de , Portari Guilherme Vannucchi
Published: March 2019

ABSTRACT This study presents data on the centesimal composition and antioxidant compounds content of two Brazilian Cerrado fruits: Bromelia balansae Mez (gravata) and Inga laurina (Sw) Willd (inga). The centesimal composition followed the methodology recommended by the Adolfo Lutz Institute, except for lipids in which the method proposed by Bligh and Dyer was used. The dosage of vitamin C was performed by the spectrophotometric method and the Folin-Ciocalteu method was used for the phenolic compounds. In relation to the centesimal composition, both fruits presented high moisture content. Regarding proteins and lipids, the values found in the experiment were low, as well as the ashes in Inga laurina (Sw) Willd. Bromelia balansae Mez presented a considerable amount of ashes, on the carbohydrates both fruits are approximate the content found in fruits such as apple (15.2%). As for the antioxidant compounds, the fruits stood out when compared with others of this same biome, especially the phenolics. The selected fruits present considerable phenolic contents. Regarding the nutritional composition, both fruits presented low protein, lipids and caloric content, and the ashes, moisture, and carbohydrates were the most important when compared to other fruits of the same biome. The presence of phenolics and vitamin C make this fruit a promising source of antioxidant compounds whose cultivation should be stimulated.

Published: March 2019

ABSTRACT The aim of this study was to evaluate the use of Maldi-Tof MS biosensor in microbial assessment of Brazilian kefir grains. Maldi-Tof MS is a new methodology for the rapid diagnosis of microorganisms. A total of 358 microorganisms were isolated, 31 were yeasts and 327 were bacteria (divided into lactic and acetic bacteria). Microbial colonies were grown in Luria-Bertani agar medium and incubated at 35 °C for 18h and used in the identification of species by Maldi-Tof MS. The microbial population identified in Brazilian kefir grains was Lactobacillus paracasei, Saccharomyces cerevisiae, Lactobacillus plantarum, Acetobacter pasteurianus, and Acetobacter syzygii. This study demonstrated a rapid and accurate identification of the Brazilian kefir grains microorganisms using the Maldi-Tof MS biosensor. In conclusion, the Maldi-Tof MS technology can facilitate the microbiological control in a fermentation process using kefir grains as starter cultures.
Dificultades de acceso al aborto en contextos de interrupción legal del embarazo: narrativa de estudiantes de bachillerato en una comunidad campesina de México
Authors: Hernández-Rosete Daniel , Estrada-Hipólito Rocío
Published: March 2019

Resumen: En este trabajo se analizan las creencias y prácticas entre jóvenes estudiantes de bachillerato que buscan o consideran la posibilidad de interrumpir un embarazo. Se eligieron estudiantes de una escuela pública situada en un una comunidad rural y campesina de la Ciudad de México, México. Es un estudio etnográfico de corte constructivista, basado en entrevistas en profundidad a 15 mujeres de entre 18 y 24 años de edad, con vida sexual activa. Las entrevistas fueron grabadas con autorización y bajo el consentimiento informado de los participantes. Los hallazgos indican que persisten estigmas sociales que afectan la dignidad de las mujeres que eligen abortar. Sin embargo, las ideologías católicas no parecen ser persuasivas para que las informantes decidan continuar con un embarazo que no desean. En todo caso, la falta de confidencia en las clínicas puede llevar a las jóvenes a optar por espacios clandestinos o a la automedicación, generalmente basada en herbolaria y pastillas abortivas. Llama la atención que las informantes reconocieron que no usaban preservativos y que eventualmente emplean anticonceptivos orales. Los sistemas de salud públicos en la comunidad no siempre garantizan la confidencialidad para interrumpir legalmente un embarazo, por eso no son contemplados por las jóvenes entrevistadas como la primera opción para suspender la gestación. Por otro lado, es muy necesaria la consolidación de proyectos educativos en sexualidad que permitan a las jóvenes evitar embarazos que no desean y puedan ejercer plenamente sus derechos sexuales y reproductivos. Además, es importante incluir acciones relativas a la sensibilización y capacitación de profesionales de las instituciones de enseñanza.

Abstract: This study aims to describe the prevalence of sleep disturbances and daytime fatigue and their association with socio-demographic and behavioral factors. Data from the Brazilian National Health Survey conducted in 2013 with 60,202 adults (≥ 18 years old) were used. The outcomes evaluated were self-reported sleep disturbances and daytime fatigue in the last two weeks. Sleep disturbance was defined as the presence of difficulty to fall asleep, frequently waking up during the night or sleeping more than usual; daytime fatigue was defined as the presence of not feeling rested and motivated during the day, feeling tired and lacking energy. Sociodemographic, lifestyle and chronic health aspects were explored as exposures for both outcomes. Prevalence of sleep disturbances and daytime fatigue were 14.9% (14.4-15.4) and 11.9% (11.4-12.3), respectively. Both outcomes were more common in women, older people, people with no formal education, smokers and among physically inactive individuals. The association with education was inverse (the highest the level of education the lower the prevalence ratio - PR - of sleep disturbances and daytime fatigue; adjusted p-value for trend < 0.001). Prevalence of sleep disturbances combined with daytime fatigue was 6.7% (6.4-7.1) and was about 6 times higher among those with three or more chronic health disturbances (PR = 6.2; 95%CI: 5.3-7.2). Strategies to decrease the prevalence of sleep disturbances and daytime fatigue should be encouraged and focused on chronically ill individuals that share other modifiable risk factors.

Resumo: Avaliar os efeitos da idade, período e coorte de nascimento (APC) na evolução temporal da mortalidade por câncer do ovário no Brasil e suas grandes regiões, entre o período de 1980 a 2014. Estudo ecológico de tendência temporal em que foram utilizados modelos APC com uma abordagem bayesiana e o método determinístico INLA (Integrated Nested Laplace Approximations) na inferência dos parâmetros. Os dados de mortalidade e os dados populacionais foram obtidos junto ao Departamento de Informática do Sistema Único de Saúde. As taxas de mortalidade por câncer do ovário, segundo região geográfica, foram padronizadas pelo método direito, após correção dos óbitos para causas maldefinidas e diagnóstico incompleto de câncer. No período de estudo, o Brasil apresentou 4,91 óbitos por câncer do ovário por 100 mil mulheres, as regiões Sul (5,66) e Sudeste (5,70) apresentaram as maiores taxas por 100 mil mulheres, e a Região Norte a menor (3,13/100 mil mulheres). Houve aumento progressivo da mortalidade com o avançar da idade em todas as regiões. O modelo APC multivariado de melhor ajuste evidenciou risco positivo de morte no Centro-oeste e Nordeste entre 2010-2014 e, a partir do período de 1995-1999, na Região Sul. Observou-se, ainda, risco positivo e significativo de morte para as coortes mais antigas no Sul e Sudeste, e risco reduzido para as coortes mais jovens. O inverso foi observado nas regiões Norte e Nordeste. Evidenciou-se um padrão heterogêneo na evolução temporal da mortalidade por câncer do ovário nas regiões geográficas brasileiras, o que pode estar relacionado aos distintos processos de transição demográfica e epidemiológica vivenciados por estas regiões.

Published: March 2019

Abstract The use of two-implant overdentures improves mastication of edentulous elderly patients. However, little is known about the effects of single-implant overdentures (SIO) on oral perception and masticatory function in such elders. This study compared the effects of conventional complete dentures (CD) and SIO on the oral sensorimotor ability (OSA), masticatory function, and nutritional intake of elderly people with residual alveolar mandibular height classified as Class III or IV according to the American College of Prosthodontics. Twelve elders first received new conventional CD, which were later converted to SIO. All variables were evaluated after use of each prosthesis for 2 months. To evaluate OSA, elders closed their eyes and orally identified test pieces prepared from raw carrots. A kinesiographic device was used to measure chewing movements during mastication of a test material (Optocal). Masticatory performance (MP) was determined with the sieving method, and a 3-day food diary verified nutrient intake based on a standard Brazilian Food Composition Table. Data were analyzed using the Wilcoxon signed rank test and Student’s paired t test (P < 0.05). OSA results did not differ according to prosthesis type. However, opening and closing velocities during chewing and MP increased after SIO insertion (P < 0.05). Although no difference was observed in the intake of most nutrients, sodium ingestion decreased after SIO insertion (P < 0.05). SIO use had no effect on OSA, but significantly improved mastication and sodium intake of elders with decreased residual ridges height (Brazilian Registry of Clinical Trials #RBR-3kgttj).

Published: March 2019

Abstract The purpose of this study was to evaluate the inflammatory process following direct pulp capping during pregnancy. This experimental study involved 48 maxillary first molars of female Wistar rats. The procedures were performed in pregnant and non-pregnant animals (n =20 each). Direct pulp capping with mineral trioxide aggregate (MTA) and restoration with a light-cured resin composite was performed in half of exposed pulp specimens. In the other half of specimens, light-cured composite was placed directly on the exposed pulp. In the control groups (n=4 each), no intervention was performed. Animals were euthanized at 3 and 7 days. All sections (three per slide) were viewed under an optical microscope. One previously calibrated pathologist performed descriptive analysis and assigned scores for inflammatory response and tissue organization adjacent to the pulp exposure. The Kappa value for intra-examiner variability was 0.91. At 3 days, in animals treated with MTA, inflammatory infiltrate was absent in non-pregnant animals while mild inflammatory infiltrate was observed in some pregnant animals. The inflammatory response ranged from mild to severe in both groups treated with composite alone. At 7 days, the inflammatory response was more intense in pregnant than in non-pregnant animals treated with MTA; while this difference were not evident in animals treated with composite alone. In conclusion, pregnancy may not influence the inflammatory process following direct pulp capping with light-cured resin composite, which was always harmful to the pulp; while the tissue response after the direct pulp with MTA were more favorable in non-pregnant animals.

Abstract The aim of this study was to evaluate the effect of a lower dose of parathyroid hormone- PTH (1-34) on osteogenic potential of bone healing around titanium implants inserted into the tibia of rats. A blind parallel study was conducted in 45 adult male Wistar rats. Each rat received one titanium implant (4.5 x 2.2 mm) and was randomly assigned to receive subcutaneous injections, three times/week for 30 days, of the following treatments: group 1 - 40 µg/kg of PTH (1-34) (n=15); group 2 - 2 µg/kg of PTH (1-34) (n=15) and; group 3 - only the vehicle required for hormone dissolution (n=15). Thirty days after surgery, the animals were sacrificed and specimens containing the implant and the surrounding bone were removed and processed for non-decalcified sections. The sections were evaluated according to the following histometric parameters: proportion of mineralized tissue (PMT) adjacent to the implant threads (500 µm band); bone filling within the limits of the threads (BF) and; bone-to-implant contact (BIC). For the cortical region, both hormone dosages (groups 1 and 2) promoted better results, for all parameters, when compared to control group (p<0.05). Similar results were observed for the BF parameter in the cancellous region (p=0.0394). Therefore, systemic administration of PTH (1-34) stimulates bone formation around titanium implants, even at low doses.

Abstract This study evaluated gloss and color changes of esthetic restorative materials subjected to different acidic beverages. Specimens of resin composites (Z350XT (Z350), IPS Empress Direct (ED), Charisma Diamond (CD)) were prepared and the initial surface gloss and color (ΔE) were measured (n=10). Then, the specimens were immersed in 4 mL of each of the different beverages (cranberry juice; Coca-Cola; coffee or artificial saliva) during 15 min, 3x/day for 14 days and new gloss and color readings were obtained. Color change was evaluated with the ΔE formula and gloss change values were obtained by the formula: (final gloss - initial gloss). Data was submitted to two-way ANOVA followed by Tukey’s post hoc test (a=0.05). CD showed the lowest color change among resin composites. The highest ΔE values were obtained after immersion in coffee and cranberry juice. Coffee promoted the highest gloss change (worst gloss retention), followed by cranberry juice, Coca-cola and artificial saliva (p<0.05). The type of beverage significantly influenced the gloss of resin composites. Coca-cola reduced gloss of the three resin composites in a similar manner. Coffee affected the ED gloss more than that of Z350 and CD, while cranberry juice affected Z350 more than ED and CD. Saliva had a more pronounced effect on the gloss retention of CD than ED. The beverages used in this study influenced the optical surface properties of the composites studied.

Abstract The aim of this study was to evaluate different conditioning protocols and sonic/ultrasonic application of an infiltrant resin (IR) in artificial white spot lesions (AWSL). the V/L surfaces of 48 molars were induced to an AWSL and divided in 6 groups, according to the conditioning protocols and application technique: 15% hydrochloric acid (HA) + manual application of the IR; HA + 37% phosphoric acid (PA) + manual application of the IR; HA + ultrasonic application (U) of the IR; HA + sonic application (S) of the IR; PA+HA+S; and PA+HA+U. For the Penetration Depth (PD), the crowns were etched with HA for 120s. The IR Icon® (DMG) was applied according to the manufacturer`s instructions. The crowns were dye penetrated (0.1% red fluorophore rhodamine B isothiocyanate for 12h) and bleached with 30% hydrogen peroxide for 12 h. The discs were immersed in a 50% ethanol solution, containing 100 µM of sodium fluorescein. The PD (in µm) was measured using confocal laser scanning microscopy (20x). The bond strength (BS) was performed by michoshear test (0.5 mm/min). Data were submitted to 2-way ANOVA and Tukey (α=0.05). For BS, the interaction was not significant (p>0.05). For PD, the main factors were significant (application - p<0.001; conditioning technique - p=0.003). The ultrasonic application showed the highest PD values. PA+HA presented higher results than HA. The sonic/ultrasonic applications and the use of phosphoric acid prior to hydrochloric acid improved PD of the infiltrant resin. Conditioning protocols or application techniques did not influence BS values.

Abstract This study aimed to assess the effects of low molecular weight heparin (LMWH) on alveolar bone loss (ABL), blood count, and counting of megakaryocytes and adipocytes in male Wistar rats. Forty male 60-day Wistar rats were randomly divided into four groups: Control (C), Periodontal Disease (PD), Heparin (Hp) and Heparin + Periodontal Disease (Hp+PD). LMWH was applied for 60 days at doses of 1 ml/kg/day. Blood samples were collected at baseline, 30 and 60. On day-49, PD and Hp+PD groups were subjected to ligature-induced periodontitis around second upper right molar. The left side was assessed as spontaneous alveolar bone loss. Mean ABL in the side with ligature showed significantly different between C (0.35±0.07 mm) and Hp+DP (0.49±0.09 mm) groups (p<0.001), between PD (0.55±0.11 mm) and Hp (0.32±0.06 mm) groups (p<0.001) and between Hp and Hp+DP groups (p<0.001). No significant differences were found among groups for ABL in the side without ligature. Animal weight, food intake, and water consumption showed no statistically significant difference among groups. Megakaryocytes and adipocytes were counted using optical microscopy and no statistically significant differences were found. Within-groups, there were an increase and a decrease, respectively, in the counting of lymphocytes (p=0.005 for C and p=0.009 for Hp+PD groups only) and leukocytes (p=0.003 for C, p=0.001 for PD, p=0.002 for Hp, and p<0.001 for Hp+PD groups). There was no decrease in the number of platelets in the three collection periods. LMWH was not able to affect ABL, but it may change the blood counting, especially increasing lymphocytes.

Abstract This study discusses a method to determine the root canal anatomic dimension by using e-Vol DX software. The methodology consists in initially establishes the correct positions which will be measured, define the point on the edge of the anatomical structure, and next adjust the intermediate position in the grayscale of CBCT image. Afterward, thin sections (0.10 mm) are obtained from 3D reconstructed slices in the filter for the measurements, in order to determine the edge of the anatomical surface in the axial plane. A replication of positions in 3D mode is done in multiplanar reconstruction (MPR) of CBCT images, where the correct position is established with the aid of a positioning guide. The 3D density is adjusted so that it is in the same dimension as the 2D image, and a dimension calibration occurs to the point where there is a coincidence between 3D and 2D. This calibration is done only at the beginning of the measurement. Next, the intermediate position of the division between the grayscale is verified in the CBCT scan. Once one side has been completed, it is moved to the other side and follows the same guidelines described above. When setting the position of the courses in the other margin, being that 2D mode is used as reference. Thus, one obtains the required measure, being checked in the two points. The creation of this filter in the e-Vol DX software for measurement, and its appropriate management, allows more effective applications when it is desired to obtain diameters of anatomical structures.

ABSTRACT: Blackberry is part of the small-fruit group and the blackberry cultivation area is expanding as an important option for small farmers using the agroecological production system. Mites are prominent among the world’s major crop pests, as they can affect plants from growth to fruiting. The objective of this study was to evaluate the occurrence of phytophagous and predatory mites in different blackberry genotypes in the municipality of Pelotas, RS, Brazil. This study was carried out in the period Nov. 2015 - Oct. 2016, totaling 14 samples. A total of 11,158 mites were collected [phytophagous (5940) and predatory (323) mites, and those with varied feeding habits (4895)], which were distributed in 8 families. The species Neotetranychus asper (Feres & Flechtmann, 2000), Diptacus rubuscolum (Trinidad, Duarte & Navia, 2018), and Acalitus orthomerus (Keifer, 1951) had highest occurrence. According to the faunistic classification, the N. asper phytophagous species is predominant in genotypes 128 and 178; whereas, D. rubuscolum is predominant in genotype 132. Monitoring of these genotypes is recommended to detect possible damage to the crop.

ABSTRACT: The aim of the present study was to explore the association between milk protein content and casein micelle size and to examine the effects of casein micelle size on enzymatic curd strength and dry matter curd yield using reduced laboratory-scale cheese production. In this research, 140 bulk tank milk samples were collected at dairy farms. The traits were analyzed using two linear models, including only fixed effects. Smaller micelles were associated with higher κ-casein and lower αs-casein contents. The casein micellar size (in the absence of the αs-casein and κ-casein effects) did not affect the enzymatic curd strength; however, smaller casein micelles combined with higher fat, lactose, casein and κ-casein contents exhibited a favorable effect on the dry matter curd yield. Overall, results of the present study provide new insights into the importance of casein micelle size for optimizing cheese production.

ABSTRACT: This study aimed to comprehend rural tourism marketing through the visitors’ eyes and discuss its sustainability. What makes rural tourism marketing more sophisticated and complex is that it is a service marketing, associated with agricultural activities, natural conditions and rural areas, and the main providers have no experience in rural tourism or service marketing. The study investigated perception of visitors in a small village, Kuyucak, in the Southwest part of Turkey, where rural tourism based on lavender production has recently developed. Results of the analysis of 175 questionnaires completed by visitors online showed that more than half of the respondents had heard and got information about the village via social media. Although, the main purpose of their visit was stated as nature/rural experience and recreation/holiday, the primary motivation of the majority was taking and sharing photos via social media tools. Appearance of lavender and previous social media sharing are very important determinants in the decision-making and expectations of visitors. Results of the factor analysis showed that two components composed of the variables regarding pre-visit perception and the physical conditions of the village together explain sixty-five per cent of the overall satisfaction. The most important component in decision making of visitors was found their perception before visiting, which means that what they expected to see was more important than what they actually saw, which was represented by visitors’ satisfaction. Making visitors experience their pre-visit perception will contribute to the sustainability of rural tourism activities benefiting the area.

ABSTRACT: The present study aimed to describe and characterize a nosocomial outbreak caused by a multidrug resistant Salmonella Typhimurium in hospitalized calves at a veterinary medical teaching hospital from Brazil. Sixty-three (96.9%) calves showed lethargy, hyperthermia and profuse diarrhea and despite treatment, 26 (41.2%) animals died. Five animals were necropsied and stool samples of six calves were collected. The isolated strains were subjected to antimicrobial susceptibility test by disc-difusion method and were fingerprinted by ERIC-PCR. Macroscopic lesions suggestive of salmonellosis, such as fibrinonecrotic enteritis and hepatosplenomegaly were observed. Salmonellosis was confirmed by isolation of S. Typhimurium from stool samples and organs from seven affected animals. Six out of seven isolates of S. Typhimurium, exhibited 100% of similarity at ERIC-PCR, suggesting occurrence of nosocomial transmission of S. Typhimurium among the hospitalized calves. All but one S. Typhimurium isolated were resistant to marbofloxacin, enrofloxacin, florfenicol, oxytetracycline and trimethoprim/sulfamethoxazole, antimicrobial agents largely used for humans and animal treatment. This is the first study of a nosocomial outbreak of multidrug resistant S. Typhimurium in a veterinary hospital in Brazil and highlighted the need for preventive measures to reduce the risks for inpatients and humans in contact with animals.

Published: March 2019

ABSTRACT: The aim of the present study was to assess the occurrence of aflatoxins (AFs) and fumonisins (FBs) in feed ingredients (corn and soybean meal) and finishing feed in a broiler operation system, as well was to evaluate their effect on the productivity of 20 batches of broilers produced and the histology status of broilers’ liver after slaughter. Corn samples presented the highest frequencies of AFs and FBs, at mean levels of 29.1 and 2,100µg/kg, respectively. Soybean samples presented mean levels of 1.5 and 70µg/kg for AFs and FBs, respectively. Batches of broilers receiving feed containing FB levels higher than 1,000µg/kg had lower weight gain and higher mortality rates, while those fed rations with AFs equal or above the limit of quantification (LOQ) of the analytical method presented higher scores of histological changes in the liver. A dilution effect was observed for AFs and FBs from ingredients, especially corn, to feed during manufacture, whilst not enough to prevent losses in productivity. Results of this trial highlighted the need for strict control of mycotoxins in corn intended for broilers.
Reproduction and growth in a Neotropical arboreal mouse: Oecomys rutilus (Sigmodontinae: Cricetidae) in French Guiana
Authors: Catzeflis François
Published: March 2019

Abstract: Postnatal growth and development of the small Neotropical mouse Oecomys rutilus (Sigmodontinae: Cricetidae) were investigated from birth to day 143, in the laboratory. Morphometric measurements at age of 3 days, of both sexes combined, revealed body weight to be 3.4 ± 0.3 g, mean tail length as 27.4 ± 1.1 mm, and mean hind foot length as 9.3 ± 0.7 mm. Body weight was found to increase steadily until at least 69 days, whereas the instantaneous growth rates of other measurements declined earlier: the daily growth of hind foot length declined to a minimum at age of 24 days, and the growth of tail and of ear declined by the age of 33 days. Average litter size for 12 captive births was 2.5, ranging from 2 to 3. The preserved eye crystalline lens was weighted in 23 captive-born animals of known age, allowing a rough estimate of the age of reproduction in wild-caught animals. Based on the inferred relation between eye-lens weight and age, the youngest reproductive (pregnant) wild-caught females had an estimated age of 90 and 95 days.

Abstract The treatment options for aberrant right subclavian artery vary depending on the presence of Kommerell’s diverticulum. Because there is a tendency not to report mortalities of these rare cases in the literature, it is hard to reach a conclusion on treatments from the limited data on post-interventional results in these patients. We report our experience with a 67-year old patient with an aberrant right subclavian aneurysm with Kommerell’s diverticulum, diagnosed by chance.

ABSTRACT Tuberculosis continues to be a major public health problem worldwide. The aim of the present study was to evaluate the accuracy of the Xpert MTB/RIF rapid molecular test for tuberculosis, using pulmonary samples obtained from patients treated at the Júlia Kubitschek Hospital, which is operated by the Hospital Foundation of the State of Minas Gerais, in the city of Belo Horizonte, Brazil. This was a retrospective study comparing the Xpert MTB/RIF test results with those of standard culture for Mycobacterium tuberculosis and phenotypic susceptibility tests. Although the Xpert MTB/RIF test showed high accuracy for the detection of M. tuberculosis and its resistance to rifampin, attention must be given to the clinical status of the patient, in relation to the test results, as well as to the limitations of molecular tests.
