Opis:
Purpose: To examine the relationship between depression and quality of life in elderly patients with glaucoma. Materials and methods: The study was conducted as a descriptive and cross-sectional research. The sample of the work consists of 130 patients aged 60 years and over who were followed up at Mersin University Hospital Ophtalmology Department between 01 October 2016 and 31 March 2017. The data were gathered with Personal Information Form, Geriatric Depression Scale and Modifiye GLAU-QOL 17 Glaucoma Quality of life. Number, percentage, mean, Pearson Correlation, Student`s t test, ANOVA test, Tukey and Games-Howell statistic were used in the evaluation of the data. Results: The mean age of the patients was 67.9±7.27. The mean score of geriatric depression scale of the patients was 15,23±5,52. It was determined that 16,2% of the patiens had possible depression and 62,3% had definite depression. The median Glau–QOL-17 Glaucoma Quality of Life Questionnaire subcale scores of the patients were as follows: daily living (3,58±3,25), driving (3,23±2,53), worry (5,26±3,47), self-assesment (6,4±3,07), psychology (4,08±2,74), feeling oppressed (4,39±2,35) and taking responsibility (3,56±1,86). The mean total score was 34.44±15.29. There was a negative and statistically significant relationship between the age of the patients and the scores of geriatric depression and the scores of age and quality of life. Conclusions: Elderly patients with glaucoma are at a major risk for depression and their quality of life is negatively affected.

Opis:
The depressing properties of sodium polyacrylate (PA-Na) for calcite from scheelite were studied by microflotation experiments, zeta potentials, X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) calculation. Flotation results revealed that the selective depression effect of PA-Na was better than that of sodium silicate (Na2SiO3), and PA-Na can depress calcite more effectively than scheelite. The flotation recovery of scheelite and calcite kept at about 75% and 15% respectively at the pulp pH 9.3~9.6 and PA-Na concentration from 37.5 mg/dm3 to 50 mg/dm3. The zeta potentials of the minerals were significantly altered and the zeta potential of calcite became more negative than scheelite. XPS analysis deduced the occurrence of chemisorption between PA-Na and mineral surfaces, and the chemisorption of PA-Na on calcite was stronger than on scheelite. The results from DFT calculation demonstrated that the absolute value of the adsorption energy in the presence of PA-Na on the surface of calcite {104} was larger than on the surface of scheelite {111}. With the combination of the analysis, it could be concluded that calcite was more easily depressed than scheelite, and this finding remarkably matched with the microflotation experimental results. Furthermore, by using PA-Na as depressant, the flotation separation of scheelite from calcite can be achieved by controlling the flotation pH and PA-Na dosage.

Opis:
Introduction. Every farming method, whether conventional or organic, has been associated with some sort of risky behaviors leading to health issues among farmers. Substantial evidence is not available in the literature to determine whether the magnitudes of health outcomes vary between conventional and organic farmers. The study investigated whether selfreported neurological and mental health symptoms differ between conventional and organic farmers living in Indiana, USA. Materials and method. A self-reported questionnaire survey collected information from 200 conventional and 157 organic farmers of Indiana on demographic characteristics, depression and neurological symptoms. Statistical analyses were conducted to observe the differences in self-reported symptoms by groups of farmers. Results. It was observed that the conventional farmers had significantly higher age-adjusted mean neurological symptom score (p<0.01) than the organic farmers. Regression models revealed positive and significant associations of conventional farming with total (β =1.34; p=0.02), sensory (β =0.83; p=0.001) and behavioural (β =0.09; p=0.03) symptoms after accounting for age, income, education and years in farming. Positive but non-significant associations were also observed in conventional farmers with cognitive and motor symptoms, and with all subscales of depression symptoms in the adjusted models. Conclusion. The findings obtained suggest the importance of a larger study to further explain the difference in mental and neurological health effects in these two categories of farmers.

Opis:
Tenrecs (Tenrecoidea) and golden moles(Chrysochloroidea) are among the most enigmatic mammals alive today. Molecular data strongly support their inclusion in the morphologically diverse clade Afrotheria, and suggest that the two lineages split near the K−T boundary, but the only undoubted fossil representatives of each superfamily are from early Miocene (~20 Ma) deposits in East Africa. A recent analysis of partial mandibles and maxillae of Eochrysochloris, Jawharia, and Widanelfarasia, from the latest Eocene and earliest Oligocene of Egypt, led to the suggestion that the derived “zalambdomorph” molar occlusal pattern (i.e., extreme reduction or loss of upper molar metacones and lower molar talonids) seen in tenrecoids and chrysochloroids evolved independently in the two lineages, and that tenrecoids might be derived from a dilambdomorph group of “insectivoran−grade” placentals that includes forms such as Widanelfarasia. Here I describe the oldest afrosoricid from the Fayum region, ~37 Ma Dilambdogale gheerbranti gen. et sp. nov., and the youngest, ~30 Ma Qatranilestes oligocaenus gen. et sp. nov. Dilambdogale is the most generalized of the Fayum afrosoricids, exhibiting relatively broad and well−developed molar talonids and a dilambdomorph arrangement of the buccal crests on the upper molars, whereas Qatranilestesis the most derived in showing relatively extreme reduction of molar talonids. These occurrences are consistent with a scenario in which features of the zalambdomorph occlusal complex were acquired independently and gradually through the later Paleogene. Phylogenetic analysis places Dilambdogale and Widanelfarasia as sister taxa to the exclusion of crown afrosoricids, but derived features that these taxa share with early Miocene Protenrec hint at the possibility that both taxa might be stem tenrecoids. Late Paleocene Todralestes and Afrodon from Morocco are similarly placed as stem afrosoricids, indicating that African adapisoriculids (including Garatherium) might also be relevant to the origin of the tenrecoid and chrysochloroid clades.

Opis:
Objective. The study was undertaken to evaluate the antidepressant activity of ethanolic extract of Ferula asafoetida oleo gum resins. Materials and Methods. Five groups of rats (180–200g) and mice (20–30g) of both genders, each group comprising six animals, were used (i.e., normal, positive control, standard, FAEE 200mg/kg, and FAEE 400mg/kg treated groups). Forced swimming test (FST), Tail suspension test (TST), Potentiation of Norepinephrine-Induced Toxicity (PNEIT), Haloperidol- Induced Catalepsy (HIC), and Reserpine-Induced Hypothermia (RIH), were used as the validate models of depression in rodents. The study was confirmed by brain monoamines estimation (i.e. Dopamine, Norepinephrine and 5-HT), MAO levels and invivo antioxidant studies (CAT and SOD). Results. FAEE treated animals showed a significant and dose dependent effect on a decrease in immobility time in FST, TST, and decrease in catalepsy time in HIC. FAEE and imipramine (15mg/kg) showed a significant increase in body temperature in RIH, and also showed a potent lethality in PNEIT. FAEE treated animals showed a significant increase in the levels of brain monoamines, in vivo antioxidants, and a significant decrease in MAO levels. Conclusion. Results of present study indicate that FAEE has potent antidepressant-like activity, and this effect may be due to the anti-oxidant property of Ferulic acid and umbelliferone, or may be due to neuroprotective activity of other major phytoconstituents, e.g. flavonoids, phenolic acids and polysulfide compounds. To identify the particular compound responsible for the antidepressant-like activity required further molecular level studies.

Opis:
Na łąkach RZD w Minikowie, położonych w dolinie malowniczego Kanału Bydgoskiego, znajdującego się w wydzielonym obszarze Natura 2000 w bydgoskim regionie PL02, w 2006 r., przeprowadzono pomiary wysokości terenu nad poziomem morza i porównano je z wysokościami z lat 1916 i 1963. W latach 2006–2007 określono dynamikę zmian poziomu wody gruntowej w przekroju poprzecznym całej doliny. Z pomiarów wysokości terenu wynika, że w latach 1916–2006 wyniesienie doliny nad poziomem morza uległo obniżeniu od kilkudziesięciu do ponad 250 cm. Najmniejsze obniżenie stwierdzono na skraju doliny. Wzrastało ono do głównego cieku, tzw. Rowu Pruskiego. Obecnie znaczna część doliny, o szerokości ok. 940 m, znajduje się w depresji w stosunku do wód Kanału Bydgoskiego. Z pomiaru poziomu wody gruntowej w 15 studzienkach usytuowanych w poprzek doliny wynika, że najbardziej uzależniony był on od ilości opadów w sezonie wegetacyjnym, odległości od Rowu Pruskiego, a w minimalnym stopniu - od wód wysiękowych.
In meadows of the Agricultural Experimental Station at Minikowo located in the valley of the picturesque Bydgoszcz Canal, currently within Natura 2000 area, in PL02 Bydgoszcz region, the absolute elevations were measured in 2006 and compared with the elevations recorded in 1916 and 1963. The dynamic of ground water level across the valley was determined in the years 2006–2007. Field measurements showed that between 1916 and 2006 the elevation of the valley above sea level decreased from a few dozen to over 200 cm. The lowest reduction in the height was demonstrated on the valley margin and it increased to the main so-called Prussian Ditch. At present a considerable part of the valley about 940 m wide is in the depression in relation to the water level of the Bydgoszcz Canal. The groundwater table measured in 15 drains located across the valley depended most on the rainfall during the vegetation period and on the distance from the Prussian Ditch. Its dependence on the distance from seepage waters was, however, weak.

Opis:
The study is to investigate the relationship between performance appraisal politics and employee performance in Fire Fighter Services of Canada, Malaysia and Pakistan by considering updated literature review related to research problem. The semi-structured questionnaires were used to collect data from total 445 valid respondents (115 from each country) out of 750 sample size through purposive sampling technique. In this cross-sectional research we employed Partial Least Squares Structural Equation Modeling (PLS-SEM) for the data analysis. The results confirmed that performance appraisal politics has negatively influenced the employees’ performances in all three distinctive economies. Through funnel approach, it was evident that higher politics is evident in Pakistan, which is the least developed country among three. However, the visible traces of performance appraisal politics are evident in Canada too. Moreover, the higher anxiety and depression leads to reduce working efficiency of operational level employees. The current study is the pioneer in examining the relationship between performance appraisal politics and employee performance in the context of contrasting economies; developed and emerging economies. The study framework is significant in empirically testing other public and private sectors to examine the variables of interest. The managerial implications are based on the present findings to improve the quality of performances.
Badanie ma na celu analizę związku między polityką oceny wyników a wynikami pracowników w służbach straży pożarnej w Kanadzie, Malezji i Pakistanie, biorąc pod uwagę zaktualizowany przegląd literatury dotyczący problemu badawczego. Kwestionariusze, częściowo ustrukturyzowane, zostały wykorzystane do zebrania danych z łącznej liczby 445 ważnych respondentów (115 z każdego kraju) z 750 wielkości próby poprzez celową technikę pobierania próbek. W tym przekrojowym badaniu do analizy danych wykorzystano modelowanie równania metodą najmniejszych kwadratów (PLS-SEM). Wyniki potwierdziły, że polityka oceny wyników negatywnie wpłynęła na wyniki pracowników we wszystkich trzech wyróżniających się krajach. Poprzez podejście lejkowe okazało się, że wyższa polityka jest widoczna w Pakistanie, który jest najsłabiej rozwiniętym krajem pośród trzech. Jednak widoczne ślady polityki oceny wyników są również widoczne w Kanadzie. Ponadto wyższy lęk i depresja prowadzi do zmniejszenia wydajności pracy pracowników na poziomie operacyjnym. Obecne badanie jest pionierem w badaniu związku między polityką oceny wyników a wynikami pracowników w kontekście kontrastujących gospodarek; rozwinięte i wschodzące gospodarki. Ramy badania są istotne w empirycznym testowaniu innych sektorów publicznych i prywatnych w celu zbadania zmiennych będących przedmiotem zainteresowania. Implikacje zarządcze opierają się na obecnych ustaleniach w celu poprawy jakości występów.

Opis:
Depression is a mental illness and is considered to be a global threat. It is designated as burden of disease. There is therefore an intense need to improve the therapeutic response of antidepressants. India beholds a wide fraction (Agaricus bisporus and Pleurotus ostreatus ) as a vital source of non-hallucinogenic indole compounds. The amino acids L-tryptophan and 5-hydroxytryptophan (5-HTP) are precursors of serotonin. 5-HTP is a potential antidepressant that can cross the blood-brain barrier (BBB) at a high rate and is converted into serotonin more efficiently. Drug delivery across this blockade remains a challenge due to the stimulation of efflux pump receptors called permeability glycoprotein (P-gp). This work reports a comparative phytochemical assay and profiling of nonhallucinogenic tryptophan metabolites using HPLC from two organic extracts of edible mushrooms. The efficacy of the eluted compounds was authenticated as P-gp inhibitors with in vitro and in silico studies. The following four derivatives were obtained from the methanol and ethanol extracts of the mushrooms: 5-hydroxy-L-tryptophan (5HTR), 5-hydroxy tryptamine (5-HT), L-tryptophan (L-Trp), and tryptamine (TA). In vitro and molecular docking studies targeting P-gp (minimum energy: -64.38 and -83.93 kcal/mol, respectively) substantiated the ability of mushroom-derived metabolites to facilitate drug delivery in the brain. This study verified that mushrooms containing non-hallucinogenic metabolites can act as psychoactive nutraceuticals that are significant for enhancing mental health. The high therapeutic efficacy, these mushrooms can serve as ideal neurological drug leads to fortify treatment for mental illness.

Opis:
Celem artykułu jest wskazanie, że brak współdziałania rodziców, lekarzy, systemu edukacyjnego oraz prawnego może przeważyć szalę okoliczności kryzysowych, przyczyniając się, pośrednio, do incydentów krańcowych, tj. „zabójstw szkolnych” i/lub samobójstw. Za podstawę empiryczną w artykule posłużyła analiza studium przypadku masakry z Columbine High School z 1999 r. Obok niedostatecznego współdziałania otoczenia, które nie rozpoznało poprawnie zaburzeń (psychopatia, depresja) i ewolucji kryzysu psychicznego u sprawców, hipotezy badawcze identyfikują jako zmienne korelacyjne tragedii: lekceważenie zjawiska bullyingu, doświadczanego przez Harrisa i Klebolda przez co najmniej cztery lata w krytycznym etapie życia, tj. między dwunastym a siedemnastym rokiem życia, oraz dysfunkcyjny charakter więzi między nimi. Wskazano na niepożądane skutki incydentu, w postaci zachowań naśladowniczych na świecie, m.in. z powodu gloryfikacji sprawców oraz wiralnego rozprzestrzenia się opisu incydentu w sieci i popkulturze. Sformułowano potencjalne kierunki pogłębionych badań, w tym badań o charakterze ilościowym, nad zjawiskiem bullyingu i cyberbullyingu wśród młodzieży, jak również rekomendacje dla wybranych decydentów.
The objective of the paper is to posit that family care, educational systems, institutions, such as healthcare and law enforcement, when they fail to act in unison, may, in fact, contribute indirectly to a volatile school crisis, which in turn may evolve into disasters, such as school shootings and/or suicide. The 1999 Columbine High School massacre, compiled into a case study, has served as the empirical source for the study. Next to the poorly synchronised family and institutional efforts to correctly diagnose psychopathic traits in one perpetrator and depression in the other, and failure to recognise their acute emotional crisis, two other variables contributing to the Columbine High shooting have been proposed. It is hypothesised that bullying (largely undermined and underestimated) to which Harris and Klebold had been exposed for at least four years, during the milestone 12 to 17 life stage, and the dysfunctional relationship between them, might have been the other massacre driving agents. Several negative repercussions of the Columbine shooting, such as worldwide copycat school shootings, resulting from a cult status of the Columbine murderers as well as their massive presence on the Internet and in pop culture, have been enumerated. Follow-up and further research studies have been proposed, including some quantitative projects, on bullying and cyber bullying among adolescents. Recommendations for decision makers have been listed.
