Published: August 2018

U radu su prikazani rezultati istraživanja preživljenja i rasta nekih vrsta drveća kojima bi se u slučaju potrebe mogla obaviti zamjena topola u nasadima. Pokus je postavljen na području Šumarije Valpovo, u Gospodarskoj jedinici Valpovačke podravske šume, šumski predjel Topolje, odsjek 23a. Taj lokalitet predstavlja tipičan primjer slabog uspijevanja i odumiranja nasada topola, čak i nakon višekratnih popunjavanja sadnicama topole i njege. Pokus je postavljen po shemi slučajno-bloknog rasporeda, sa šest tretiranja u četiri bloka. Tretirani su sljedeći sastojinski oblici: A – hrast lužnjak, B – poljski jasen, C – bagrem, D – hrast lužnjak s običnim grabom, E – divlja trešnja s poljskim jasenom i F – divlja trešnja s običnim grabom. Pokus je postavljen 18. studenog 2009. godine. Preživljenje biljaka je utvrđeno svake godine tijekom petogodišnjeg praćenja pokusa. Tijekom zime 2015. godine izmjerene su visine svih stabala te je određen prostorni položaj živih i odumrlih jedinki po plohicama. S obzirom na preživljenje i visine kao indikatore rasta i razvoja biljaka, najbolje su rezultate pokazali redom obični bagrem, poljski jasen i hrast lužnjak. Najlošije rezultate postigli su divlja trešnja i obični grab. S obzirom na mikroreljef, najbolje preživljenje je pokazao obični bagrem koji podjednako dobro raste u nizi i na gredi. Poljski jasen i hrast lužnjak bolje preživljenje imaju u nizi. Divlja trešnja i obični grab imaju općenito loše preživljenje, neovisno o mikroreljefu. Rezultati istraživanja pokazali su kako je nasade topola u promijenjenim stanišnim prilikama nakon višekratnih ophodnji moguće zamijeniti sa sastojinom koja svojim sastojinskim oblikom odgovara terminalnoj šumskoj zajednici istraživanoga podučja – veza i poljskog jasena s hrastom lužnjakom (Fraxino-Ulmetum laevis Slavnić 1952). Postupku treba prethoditi izrada detaljnog šumskouzgojnog plana, koji bi između ostalog definirao područja niza i greda u određenom odjelu. Nize i vlažne grede treba prepustiti poljskom jasenu koji je pokazao vrlo dobre rezultate u pokusu. Hrast lužnjak je pokazao zavidnu stabilnost i vitalitet, pa ga treba upotrebljavati u smjesi s poljskim jasenom. Obični bagrem preporuča se za najsuše lokalitete s pjeskovitim tlima koja su naglo ostala bez podzemne i poplavne vode, na kojima nema uvjeta za nastavak uzgajanja topola.

In recent decades, higher education (HE) in Chile has experienced a profound changeÂ in addition to a highly significant expansion in the coverage provided. This has givenÂ rise to concern over the relative value of HE. The existence of a constantly changingÂ job market makes both descriptive information and projective information on jobs aÂ key element for the HE system. Therefore, the Ministry of Education is implementing aÂ project known as the "Job observatoryâ€. This will help generate detailed, complete,Â projective and readily accessible information on the supply of graduates and theÂ occupationalÂ demand for HE graduates to aid individuals,organizations and the State inÂ their respective decision making processes. The outcome of the project referred toabove will be a regular publication entitled "Manual on Professional occupationsâ€.

One of the obstacles to development faced by Chile is,undoubtedly, the lowproductivity of labor and the lack of a timely inclusion of new technologies to all theÂ activities conducted in the country. Higher education centers have a dutyto make aÂ contribution in both espects, by preparing technicaland professional cadres, who will beÂ responsible for directing the process of producing goods and services in the country.The educational model implemented by DuocUC is aimed at training studentsfor the world of work through programs designed especially to achieve laborcompetency. For this purpose, it relies on the advice of the Consejos empresarialesÂ (Business Councils), formed by people directly related to activities in which future graduates will work.Â The theoreticalknowledge that these students acquire, together with a practicalapplication of what theyhave learned in laboratories that allowsimulating the reality they will find in the world of work, providesÂ a guarantee of experience in the use of current technologies.

The past decade has been a highly dynamic period for higher education in Chile, asÂ evidenced by the numerous institutions that have emerged in this field, in theirÂ composition, the number of students enrolled and in the changes experienced in theÂ preferences of applicants for different areas of knowledge. The foregoing emphasizesÂ the consolidation of the category called "Universityâ€.The changes experienced by the tertiary education system should, on the onehand, act as a warning to the education authorities, in order to implement specificÂ public policies to stimulate special areas of knowledge and, on the other hand,Â encourage educational centers to re-orient what they are offering in terms ofeducation.

Over and above the natural increases and decreasesÂ that may be observed, the paper tries to show the different dynamic trends developedÂ in the various thematic areas by making comparisons between different influentialÂ variables such as supervision systems, the region where certain education programsÂ are offered, and the type of educational establishment offering the programs.
Liderazgo escolar y conflictos socioeducativos. Un estudio exploratorio en liceos públicos chilenos
Authors: Villalobos Cristóbal , Peña Javiera , Aguirre Elisa , Guerrero Magdalena 
Published: August 2018

The research seeks to study the processes of educational conflict, giving an account of the strategies and frameworks of action implemented by school administrators in public secondary schools in Chile. In order to achieve this, a case study was carried out in eight public high schools, using several qualitative techniques. Three results are obtained. First, the conflicts that involve students as central actors mainly arise from their social, economic and cultural context. In contrast, conflicts involving adults are related to problems of micro-politics (school level) and macro-politics (field of education). The second result is related with the dynamics adopted by conflicts, where it is observed that, in most cases, conflicts tend to transition from cognitive conflicts to affective conflicts, which means that become personalized and viewed as unproductive processes for schools. Finally, and in relation to the strategies thatÂ school leaders use to handle the conflicts, it is verified that these differ depending on the actor involved. When they involve students, there are regulations and action protocols ; whereas when teachers are involved, there are generally no regular channels to proceed, and conflicts tend to be avoided or not recognized.
Noncontrast vestibular schwannoma surveillance imaging including an MR cisternographic sequence: is there a need for postcontrast imaging?
Authors: Buch Karen , Juliano Amy , Stankovic Konstantina M. , Curtin Hugh D. , Cunnane Mary Beth 
Published: August 2018

OBJECTIVEThe purpose of this study was to evaluate the use of a noncontrast MRI protocol that includes a cisternographic sequence (CISS/FIESTA/3D DRIVE) compared to a protocol that includes a gadolinium-enhanced sequence in order to determine whether a noncontrast approach could be utilized to follow vestibular schwannomas.METHODSA total of 251 patients with vestibular schwannomas who underwent MRI of the temporal bones that included both cisternographic sequence and postcontrast T1 imaging between January 2000 and January 2016 for surveillance were included in this retrospective study. The size of the vestibular schwannomas was independently assessed on a noncontrast MR cisternographic sequence and compared to size measurements on a postcontrast sequence. The evaluation of intralesional cystic components (identified as T2 signal hyperintensity) and hemorrhagic components (identified with intrinsic T1 hyperintensity) on noncontrast MR sequences was compared to evaluation on postcontrast MR sequences to determine whether additional information could be derived from the postcontrast sequences. Additionally, any potentially clinically significant, incidentally detected findings on the postcontrast T1 sequences were documented and compared with the detection of these findings on the precontrast images.RESULTSNo significant difference in vestibular schwannoma size was found when comparing measurements made on the images obtained with the MR cisternographic sequence and those made on images obtained with the postcontrast sequence (p = 0.99). Noncontrast MR images were better (detection rate of 87%) than postcontrast images for detection of cystic components. Noncontrast MR images were also better for identifying hemorrhagic components. No additional clinically relevant information regarding the tumors was identified on the postcontrast sequences.CONCLUSIONSBased on the results of this study, a noncontrast MR protocol that includes a cisternographic sequence would be sufficient for the accurate characterization of size and signal characteristics of vestibular schwannomas, obviating the need for gadolinium contrast administration for the routine surveillance of these lesions.

Endocytosis and Transcytosis of Amyloid-β Peptides by Astrocytes: A Possible Mechanism for Amyloid-β Clearance in Alzheimer’s Disease
Authors: Domínguez-Prieto Marta , Velasco Ana , Tabernero Arantxa , Medina José M. 
Published: August 2018

Amyloid-β (Aβ) peptides, Aβ40, Aβ42, and recently Aβ25 - 35, have been directly implicated in the pathogenesis of Alzheimer’s disease (AD). We have previously shown that all three peptides decrease neuronal viability, but Aβ40 also promotes synaptic disassembling. In this work, we have studied the effects of these peptides on astrocytes in primary culture and found that the three Aβ peptides were internalized by astrocytes and significantly decreased astrocyte viability, while increasing ROS production. Aβ peptide internalization is temperature-dependent, a fact that supports the idea that Aβ peptides are actively endocytosed by astrocytes. However, inhibiting caveolae formation by methyl-beta-cyclodextrin or by silencing caveolin-1 with RNA interference did not prevent Aβ endocytosis, which suggests that Aβ peptides do not use caveolae to enter astrocytes. Conversely, inhibition of clathrin-coated vesicle formation by chlorpromazine or by silencing clathrin with RNA interference significantly decreased Aβ internalization and partially reverted the decrease of astrocyte viability caused by the presence of Aβ. These results suggest that Aβ is endocytosed by clathrin-coated vesicles in astrocytes. Aβ-loaded astrocytes, when co-incubated with non-treated astrocytes in separate wells but with the same incubation medium, promoted cell death in non-treated astrocytes; a fact that was associated with the presence of Aβ inside previously unloaded astrocytes. This phenomenon was inhibited by the presence of chlorpromazine in the co-incubation medium. These results suggest that astrocyte may perform Aβ transcytosis, a process that could play a role in the clearance of Aβ peptides from the brain to cerebrospinal fluid.

Published: August 2018

BACKGROUND: 10–30% of hospital stays by older patients are drug-related. The admission phase is important for identifying drug-related problems, but taking an incorrect medication history often leads to medication errors. OBJECTIVES: To enhance medication history recording and identify drug-related problems (DRPs) of older patients admitted to emergency departments (EDs). METHODS: DRPs were identified by pharmacists-led medication reconciliation and review procedures in two EDs in Finland; Helsinki University Hospital (HUS), and Kuopio University Hospital (KUH). One-hundred-and-fifty patients aged ≥65-years, living at home and using ≥6 medicines were studied. RESULTS: 100% of patients (N = 75) in HUS and 99% in KUH (N = 75), had discrepancies in their admission-medication chart recorded by the nurse or physician. Associations between admission-diagnosis and drug-related problems were found in 12 patients (16%) in HUS and 22 patients (29%) in KUH. Of these, high-alert medications (e.g. antithrombotics, cytostatics, opioids) were linked to eight patients (11%) in HUS and six patients (8%) in KUH. Other acute DRPs were identified in 19 patients (25%) in HUS and 54 patients (72%) in KUH. Furthermore, 67 patients (89%) in HUS and all patients in KUH had non-acute DRPs. CONCLUSIONS: Medication reconciliation and review at admission of older ED patients requires improvement in Finland.

Introduction: The search for new compounds with antihypoxic and cardioprotective effects among 3-oxypyridine derivatives is promising.
Research objectives: To study the anti-hypoxic and cardioprotective effects of 3-oxypyridine derivatives.
Materials and methods: The search for compounds with an antihypoxic effect was carried out on blood leukocytes of rats in in vitro. To simulate hypoxia, Oil for Tissue Culture (SAGE) was used, 500 µl of which was applied into wells over a growth medium in order to block gas exchange. The cardioprotective effect of 3-oxypyridine derivatives was studied in the model of coronary-occlusive myocardial infarction (30 minutes of ischemia, 90 minutes of reperfusion). The level of troponin I (Tn I) was determined as a biochemical marker of myocardial damage.
Results and discussion: In the in vitro experiments, when culting white blood cells, the lead compound in the group of 3-oxypyridine derivatives was identified under code LKhT 21–16, which increases the number of viable cells in the presence of hypoxia, surpassing the reference drugs. When confirming the chemical structure of the lead compound, LHT 21–16, a high sensitivity of the NMR spectroscopy method was revealed.
In studying the cardioprotective activity in the model of coronary-occlusive myocardial infarction compound LHT 21–16 exerted a marked cardioprotective effect when reducing the size of the necrotic zone and the level of biochemical marker Tn I.
Conclusions: 3-oxypiridine derivatives have antihypoxic and cardioprotective effects, which shows in a high number of surviving cells in the presence of hypoxia in the in vitro model, a reduced size of the necrotic zone and a reduced level of Tn I in the coronary-occlusive myocardial infarction.
