Background and Aims: Re-vegetation of contaminated and disturbed landscapes can reduce the transport of toxic elements while improving soil fertility. This study evaluated whether the planting of a perennial grass with diazotrophic microbial endophytes and municipal waste compost—alone and in combination—improved phytostabilization of potentially toxic trace elements in dolomite-amended tailings from a historically mined polymetallic mineral deposit.Methods We grew Bouteloua curtipendula seedlings in tailings with hazardous concentrations of As, Cd, Pb, Mn, and Zn. We evaluated how plant growth, organic matter accumulation, and minor and trace element mobilization responded to microbial endophyte and organic amendments.Results Although most of the added endophytes were not uniquely identified, the best plant growth and fertility outcomes were achieved with a combination of amendments: dolomite to reduce acidity, a compost topdressing to accumulate nitrogen in the tailings, and a mixed consortium endophyte seed coating to synergistically increase organic carbon and grass biomass yields. Combining amendments also improved phytostabilization: compost reduced the shoot forage toxicity of B. curtipendula seedlings without reducing phytostabilized contaminant yields in the rhizosphere, while endophyte inoculated grass marginally reduced total and water-extractable concentrations of toxic trace elements through enhanced mobilization.Conclusion The most effective means of reclaiming these acidic, polymetallic tailings is with a simultaneous dolomite, compost, and endophyte seed treatment.

Background Although fertilization and crop rotation practices are commonly used worldwide in agriculture to maximize crop yields, their long-term effect on the structures of soil microorganisms is still poorly understood. This study investigated the long-term impact of fertilization and crop rotation on soil microbial diversity and the microbial community structure in four different locations with three soil types. Since 1996, manure (MF; 330 kg N/ha), sewage sludge (SF; 330 and SF3x; 990 kg N/ha), and NPK (NPK; 330 kg N/ha) fertilizers were periodically applied to the soils classified as chernozem, luvisol and cambisol, which are among the most abundant or fertile soils used for agricultural purposes in the world. In these soils, potato (Solanum tuberosum L.), winter wheat (Triticum aestivum L.), and spring barley (Hordeum vulgare L.) were rotated every three years. Results Soil chemistry, which was significantly associated with location, fertilization, crop rotation, and the interaction of fertilization and location, was the dominant driver of soil microbial communities, both prokaryotic and fungal. A direct effect of long-term crop rotation and fertilization on the structure of their communities was confirmed, although there was no evidence of their influence on microbial diversity. Fungal and bacterial communities responded differently to fertilization treatments; prokaryotic communities were only significantly different from the control soil (CF) in soils treated with MF and SF3x, while fungal communities differed across all treatments. Indicator genera were identified for different treatments. These taxa were either specific for their decomposition activities or fungal plant pathogens. Sequential rotation of the three crops restricted the growth of several of the indicator plant pathogens. Conclusions Long-term fertilization and crop rotation significantly altered microbial community structure in the soil. While fertilization affected soil microorganisms mainly through changes in nutrient profile, crop rotations lead to the attraction and repulsion of specific plant pathogens. Such changes in soil microbial communities need to be considered when planning soil management.

Background and aim of the work: Negative health effects have been associated with the changes in lifestyles in relation with the low income of population. Consequently, in our study we investigated the frequency changes of alcohol and smoke consumption, physical activity, and quality of life in families of Marche Region in Central Italy. Methods: In the period 2016-2017, an anonymous questionnaire has been distributed to junior highschool students of Camerino, Fabriano, and Civitanova Marche of Marche Region. The Manchester Short Assessment of Quality of Life (MANSA), was used to assess subjective quality of life. Results: Data obtained in this research were used to analyze lifestyle changes, specifically those involving alcohol consumption, smoking, and physical activity, and to assess perceived general quality of life. In all categories of population, an increase of frequency in alcohol consumption was observed. On the contrary, for the tobacco smoke we observed a reduction in particular in the parents category. The MANSA mean value was 4.5 with a Standard Deviation of 1.3. Conclusions: As underlighted, also, by results of the MANSA test we can hypothesize a reduction in the family income produces a change of lifestyles. (www.actabiomedica.it)

An understanding of how fertilization influences endophytes is crucial for sustainable agriculture, since the manipulation of the plant microbiome could affect plant fitness and productivity. This study was focused on the response of microbial communities in the soil and tubers to the regular application of manure (MF, 330 kg N/ha), sewage sludge (SF, 330 and SF3x, 990 kg N/ha), and chemical fertilizer (NPK, 330-90-300 kg N-P-K/ha). Unfertilized soil was used as a control (CF), and the experiment was set up at two distinct sites. All fertilization treatments significantly altered the prokaryotic and fungal communities in soil, whereas the influence of fertilization on the community of endophytes differed for each site. At the site with cambisol, prokaryotic and fungal endophytes were significantly shifted by MF and SF3 treatments. At the site with chernozem, neither the prokaryotic nor fungal endophytic communities were significantly associated with fertilization treatments. Fertilization significantly increased the relative abundance of the plant-beneficial bacteria Stenotrophomonas, Sphingomonas and the arbuscular mycorrhizal fungi. In tubers, the relative abundance of Fusarium was lower in MF-treated soil compared to CF. Although fertilization treatments clearly influenced the soil and endophytic community structure, we did not find any indication of human pathogens being transmitted into tubers via organic fertilizers.

The economic crisis in Italy has led to profound changes in resource management not only at the macro level but also for individual families, causing substantial changes in different habits of Italians.The purpose of this research was to conduct a study on changes in family eating habits potentially triggered by the economic crisis was conducted in an area of the Marche Region in central Italy.The research was conducted in the period 2016 - 2017 by administering a specific and anonymous questionnaire.The interviewed people has reduced its food consumption. In particular, analyzing the results for the animal protein food group, there has been a reduction in purchase of beef, and an increase in that of pork. Overall fish consumption has decreased by 44%, with a decrease in the purchase of fresh fish, and an increase in that of canned fish products. Finally, consumers have reduced their purchases of fresh and canned legumes, fresh vegetables, and fresh fruit.The economic crisis seems to have changed the eating habits and food-related lifestyle choices of the subjects studied, especially in the urban area affected by the deeper economic depression. These changes are likely to have permanent social consequences, and deserve to be analyzed also in smaller territories in order to better understand the dynamics of individual choices and the social framework.

Background and aim: In the words of one observer, one of the many effects of the economic downturn has been a “health system shock” marked by reductions in the availability of healthcare resources and increases in the demand for health services. The financial situation influences negatively the low-income family groups, particularly those who normally use the government provided primary prevention services. The goal of this study was to assess the impact of the global recession on the use of medicines and medical investigation recession in different areas of the Marche Region. Methods: An anonymous questionnaire prepared by the National Institute of Statistics, modified and validated by the University of Camerino, has been distributed to junior highschool students of Central Italy to provide a statistically representative sample of families. The questionnaire has been administered in 2016-2017. Results: This article examines the results about healthcare habits, specifically, regarding medicines and medical examinations. Data obtained emphasize a reduction in the use of nonsteroidal anti-inflammatory drugs (NSAIDs). The parents category showed the higher change in medicines use (72.9%). Comparing the data of the Fabriano area with that of the Civitanova Marche area, Fabriano reported a greater reduction in the frequency of taking medicine. Concerning the medical examinations, half of the respondents (62.5%), indicated that they and their family members have regular medical check-up. Conclusions: Respondents who admitted that the economic crisis had reduced their quality of life indicated that the parents were the ones who had experienced the greatest change. This is confirmed by the information on the reduced frequency of medicine use, which affected the parents more than the children, whom they sought to protect and safeguard the most. This reduction was most marked in the Fabriano area. In contrast, in the Civitanova Marche area, with different socioeconomic characteristics, an increase in the use of all the categories of medicines was reported. Concerning visits the situation in the Marche Region appears encouraging. (www.actabiomedica.it)

Introduction The primary consumers of energy drinks were athletes, to combat fatigue, but in reality, thanks to their fast expansion and economic growth, young adults and teenagers represent the new target market. Consumption of energy drinks by both recreational and competitive athletes has increased dramatically in recent years, though they are often unaware of what is being ingested, believing to improve their physical and psychological performance. The literature shows contradictions about the capacity of energy drinks to enhance psychophysical results. In relation to probable adverse effects induced by the irregular consumption of energy drinks, which in several cases are not so clear, we decided to investigate the possible relationship between the intake of energy drinks and the presence of mental and physical stress in young people and athletes. Methods Two experimental sessions, separated at least by 1 week, according to a randomized cross-over design, following this protocol were conducted: in the first session a mental and physical stress was conducted without the consumption of energy drinks, the second after energy drinks consumption. BAI (Beck Anxiety Inventory) and BDI (Beck Depression Inventory II) test have been used to test the mental stress, and a “cycle ergometer test” to test the physical stress. Results BAI and BDI tests results showed that before the consumption of energy drinks, subjects are considered in the range of “minimal level of anxiety”, (10 and 60 percentiles) and do not report a level of depression. After the energy drinks consumption, a “mild level of anxiety” has been recorded, and the BDI showed a case with a pathological profile. The physical test recorded a small increase in the maximum heart rate was verified with the intake of an energetic beverage. Conclusions The stimulating effect of EDs on nervous system and cardiovascular system, must be checked and studied in deeper detail, because it may represent a risk for the health of young athletes., Journal of Preventive Medicine and Hygiene, Vol 59, No 1 (2018): 2018591

The aim of this study was to psychometrically evaluate the shortened version of the Spiritual Well-Being Scale (SWBS) in Czech adolescents. A nationally representative sample of 4217 adolescents participated in the 2014 Health Behaviour in School-aged Children survey. The internal consistency of the SWBS was assessed using Cronbach's alpha (alpha) and Mean Inter-Item Correlation (MIIC) values. The factor structure was evaluated using principal component analyses. After adjustment, our new seven-item version of the scale supports a two-factorial model of the SWBS with satisfactory internal consistency (alpha = 0.814, MIIC = 0.379). This version of the SWBS is suitable for measuring spiritual well-being in a secularising environment.

PURPOSE: To monitor improvements and follow-up of patients with EDs (Eating Disorders), and BED (Binge Eating Disorder) in the Regional Reference Center for the Physiopathology of Nutrition of Teramo, Italy. METHODS: All the access for EDs (diagnosed according to DSM-IV) were recorded at first visit and follow up. The diagnoses and characteristics of patients from the Teramo area, who enjoy easier access to the service were compared to those of patients from other local health authorities. The degree of improvement in BMI between the first and last appointment of patients with AN (anorexia nervosa), and the average time of treatment, were noted. Microsoft Excel was used for data storing and processing. Statistical analysis was performed by the X-Lstat software. RESULTS: Of the 169 patients registered, 90.5% were female. The average age of patients followed by the Centre for eating disorders was 29.3 (60.9% of the cases were in the youth age bracket). In local patients, the AN is corrected with greater success and in less time compared to cases of AN in active mobility. CONCLUSIONS: This study shows that an integrated multidisciplinary outpatient service provides continuity of care and more support to patients coming from the province. The data demonstrate that the ability of the outpatient structure to intercept early cases and offer effective therapeutic itineraries is directly related to its accessibility. These data provide valuable references for a more rational and thoughtful use of available resources and to begin the development of a registry of EDs in Abruzzo’s region in center of Italy.

Summary The objective of the experiment was to verify that HI-6 dimethanesulphonate (HI-6 DMS) is able to penetrate the skin in amounts sufficient to protect against organophosphate poisoning using a rat model. HI-6 2Cl is a major component of Transant, a transdermal patch, used as a protective agent against organophosphate intoxication in the Czech and Slovak armies, although there is little evidence that HI-6 would penetrate the skin in sufficient amounts. HI-6 DMS at a total amount of 127 mg or 635 mg was applied as a buffer solution on the Transant patch which was fixed on the back of the rat. Two, seven or twenty-four hours later, rats were sacrificed and blood samples were collected to determine the levels of HI -6 in plasma by HPLC on reversed phase with isocratic elution and UV/VIS detection. HI-6 was not detectable in plasma samples of animals exposed to 127 mg of HI-6 DMS. The highest levels of HI-6 (20.6 ± 18.8 ng/ml) were found in plasma of animals exposed to 635 mg of HI-6 DMS 2 hours after patch application, whereas after 7 or 24 hours the levels were very low. Based on these results, the ability of HI-6 DMS to penetrate the skin is discussed and some possibilities of improving the transdermal penetration are suggested.

OBJECTIVE: The purpose of this research was to assess the prevalence of addictive drug use among students of University of Camerino (Italy) and to verify aspects related to substance use in this population. METHODS: The survey was carried out in the form of anonymous questionnaires completed by 345 participants. Chi-square test was used for statistic evaluation. RESULTS: Most students have experienced legal addictive substances: 28.0 % of participants smoke cigarettes regularly and 23.2 % of respondents have admitted regular alcohol consumption. In addition, 50.4 % of subjects have already tried an illegal drug; the most used substance was cannabis (46.7 %), followed by cocaine (13.3 %). CONCLUSION: Our results confirmed the increased experimental use of cannabis among young people in Europe and showed a long-term use of drugs, particularly cocaine, among university students. OBJETIVO: O objetivo desta pesquisa foi avaliar o uso de drogas que causam dependência entre os estudantes da Universidade de Camerino, Italia, e verificar os aspectos relacionados ao uso de substâncias psicoativas nesta população. MÉTODOS: A pesquisa foi realizada por meio de um questionário anônimo composto por 345 participantes selecionados aleatoriamente entre os alunos da universidade. O questionário tem sido utilizado, para esse tipo de estudo na República Tcheca, desde 2002. O teste qui-quadrado foi utilizado para a avaliação estatística dos fatores, conforme o uso da substância. RESULTADOS: A maioria dos alunos entrevistados teve alguma experiência com substâncias legais que causam dependência: 28,0% dos participantes fumam cigarros regularmente e 23,2% dos entrevistados admitiram consumo regular de álcool. Além disso, 50,4% dos indivíduos já experimentaram uma droga ilícita; a substância mais experimentada foi cannabis (46,7%), seguida da cocaína (13,3%). Dos estudantes que experimentaram drogas, 19% admitiram o uso da substância no último mês (cannabis 87,5%). CONCLUSÃO: Nossos resultados confirmam o aumento experimental do uso de drogas cannabis entre os jovens na Europa e revelam um longo tempo de uso de drogas, principalmente de cocaína, entre os estudantes universitários.

The rate of chromosome segregation errors that emerge during meiosis I in the mammalian female germ line are known to increase with maternal age, however, little is known about the underlying molecular mechanism. The objective of this study was to analyze meiotic progression of mouse oocytes in relation to maternal age. Using the mouse as a model system, we analyzed the timing of nuclear envelope breakdown and the morphology of the nuclear lamina of oocytes obtained from young (2 months old) and aged females (12 months old). Oocytes obtained from older females display a significantly faster progression through meiosis I compared to the ones obtained from younger females. Furthermore, in oocytes from aged females, lamin A/C structures exhibit rapid phosphorylation and dissociation. Additionally, we also found an increased abundance of MPF components and increased translation of factors controlling translational activity in the oocytes of aged females. In conclusion, the elevated MPF activity observed in aged female oocytes affects precocious meiotic processes that can multifactorially contribute to chromosomal errors in meiosis I.

It has been demonstrated that over-expression of Bmi-1 occurs in a variety of cancers, including several types of leukemia. This gene plays a key role in the self-renewal of stem cells. Leukemic cells lacking Bmi-1 underwent proliferation arrest and showed signs of differentiation and apoptosis. These findings led to the proposal of Bmi-1 as a potential target for therapeutic intervention in cancer. In this study, we investigated the role of Bmi-1 in chronic myeloid leukemia (CML). Using qRT-PCR, we demonstrated a significantly increased level of Bmi-1 transcript in CML cells. Using array analysis, we determined the deregulation of several genes after Bmi-1 silencing. Proapoptotic genes BAD and TRADD, and CASP8, p16-INK4, BRCA2, Notch4 and Wnt-8B were elevated. PLK1, SOD1, E2F-3, two retinoblastoma binding proteins (RBQ1 and RBBP4) and HDGF were reduced after Bmi-1 inhibition. Additionally, we tested the impact of Bmi-1 siRNA on CML cell growth; however, there was no apparent change after Bmi-1 suppression. Despite the fact that Bmi-1 deregulation occurs in CML and its expression is connected to several oncogenic processes, Bmi-1 seems to play a secondary role in CML transformation.

Inhibitors of cholinesterase are important drugs for therapy of Alzheimer's disease and the search for new modifications is extensive, including dual inhibitors or multi-target hybrid compounds. The aim of the present study was a preliminary evaluation of pro-cognitive effects of newly-developed 7-MEOTA-donepezil like hybrids (compounds no. 1 and 2) and N-alkylated tacrine derivatives (compounds no. 3 and 4) using an animal model of pharmacologically-induced cognitive deficit. Male Wistar rats were subjected to tests of learning and memory in a water maze and step-through passive avoidance task. Cognitive impairment was induced by 3-quinuclidinyl benzilate (QNB, 2mgkg(-1)), administered intraperitoneally 1h before training sessions. Cholinesterase inhibitors were administered as a single therapeutic dose following the QNB at 30min at the following dose rates; 1 (25.6mgkg(-1)), 2 (12.3mgkg(-1)), 3 (5.7mgkg(-1)), 4 (5.2mgkg(-1)). The decrease in total path within the 10-swim session (water maze), the preference for target quadrant (water maze) and the entrance latency (passive avoidance) were taken as indicators of learning ability in rats. The effects of novel compounds were compared to that of standards tacrine (5.2mgkg(-1)) and donepezil (2.65mgkg(-1)). QNB significantly impaired spatial navigation as well as fear learning. Generally, the performance of rats was improved when treated with novel inhibitors and this effect reached efficiency of standard donepezil at selected doses. There was a significant improvement in the groups treated with compounds 2 and 3 in all behavioral tasks. The rest of the novel compounds succeed in the passive avoidance test. In summary, the potential of novel inhibitors (especially compounds 2 and 3) was proved and further detailed evaluation of these compounds as potential drugs for Alzheimer's disease treatment is proposed.

To analyze the contribution of the Czech population to the Y-chromosome diversity landscape of Europe and to reconstruct past demographic events, we typed 257 males from five locations for 21 UEPs. Moreover, 141 carriers of the three most common haplogroups were typed for 10 microsatellites and coalescent analyses applied. Sixteen Hg's characterized by derived alleles were identified, the most common being R1a-SRY(10831) and P-DYS257*(xR1a). The pool of haplogroups within I-M170 represented the third most common clade. Overall, the degree of population structure was low. The ages for Hg I-M170, P-DYS257*(xR1a), and R1a-SRY(10831) ap peared to be comparable and compatible with their presence during or soon after the LGM. A signal of population growth beginning in the first millennium B.C. was detected. Its similarity among the three most common Hg's indicated that growth was characteristic for a gene pool that already contained all of them. The Czech population appears to be influenced, to a very moderate extent, by genetic inputs from outside Europe in the post-Neolithic and historical times. Population growth postdated the archaeologically documented introduction of Neolithic technology and the estimated central value coincides with a period of repeated changes driven by the development of metal technologies and the associated social and trade organization.
