Authors: Eroğlu Hüseyin , Karaismailoğlu Mehmet Cengiz , Pinar Süleyman Mesut , Fidan Mehmet
Published: January 2021

This study presents the first in-depth evaluation of the morphological and anatomical characters, as well as their taxonomic importance, of the seeds of 36 taxa in subgenera Muscari, Leopoldia, Pseudomuscari and Botryanthus of the genus Muscari in Turkey, where 24 of the taxa are endemic. The results indicate that the taxa generally differ from each other in terms of seed shape and dimension. Seed dimensions vary between 1.66 mm and 3.21 mm in length, and between 1.12 mm and 2.63 mm in width. The seed surface ornamentation is grouped into nine forms: ruminate, reticulate, reticulate-areolate, reticulate-foveate, alveolate, scalariform, rugose, verrucate and areolate. The most common type is ruminate, while areolate, reticulate-foveate and scalariform ornamentation forms were found to be taxon-specific. Testa structures of the taxa examined consist in general of two different layers: the epidermis and the subepidermis in scleranchymatous or parenchymatous structures. The subepidermis may be absent in some of taxa. The structure and thickness of the epidermis and the subepidermis are very important characteristics that disclose interspecific relations among the examined taxa. We also provide a key for the identification of the studied taxa based on seed features.

Authors: Hee Kyung Kim
Published: January 2021

Background/Objectives: The purpose of this study was to analyse the effect that perceived health condition,

gerotranscendence, and wisdom have on successful aging in elders. Methods/Statistical analysis: This

study is a descriptive survey design using a convenience sampling. The subjects of this study were 94 elders

between 65 years old or above. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson’s

correlation coefficient and multiple regression using the SPSS Win 23.0 program. Findings: Successful

aging of subjects had positive correlation with perceived health condition, gerotranscendence and wisdom.

As a result of conducting the stepwise regression analysis, the explanatory power of above 2 variables was

appeared to be 57.8% including wisdom (?=.713, p<.001) and monthly household income (? =.153, p=.032).

Improvements/Applications: As a plan to achieve the successful aging of the elders through the results of

this study, the government and local governments need to develop a nursing arbitration program for elders

to have wise lives in their daily lives and to make efforts to institutionalize the customized job creation

considering the ages and conditions of the elders so that they can raise monthly household incomes.
Cecília Meireles e a revista Távola Redonda: a busca pelo graal da poesia
Authors: Mendes Karla Renata
Published: January 2021

A revista Távola Redonda circulou em Portugal entre 15 de janeiro de 1950 e julho de 1954, e teve David Mourão-Ferreira como um dos principais nomes à sua frente. Esboçando uma reação ao neorrealismo e ecoando dis­cursos manifestados na antecessora revista Presença, reivindicava uma literatura pautada pela subjetividade e pela expressão individual do au­tor. A publicação estabeleceu, assim, uma clara oposição aos neorrealistas que priorizavam uma poesia comprometida com seu momento histórico e social, ou seja, acima das nuances do “eu”. Nesse contexto e inserido no meio literário português, surge o nome de Cecília Meireles, que integrou esse rol de poetas “acolhidos” com simpatia e, mais do que isso, admiração pelas páginas da Távola. O fascículo número 12, de 29 de fevereiro de 1952, publicou quatro poemas que apareceram com o título de “Poesias inédi­tas”, além de um texto crítico, “Cecília Meireles, acerca da sua poesia”, de autoria de David Mourão-Ferreira. Dessa forma, destacam-se as forças motrizes da publicação e as proximidades que levaram a poeta brasileira a figurar na revista, salientando-se a importância de sua participação no periódico e o diálogo luso-brasileiro ali estabelecido.

Environmental Management and Higher Education: Are they Closely Related?
Authors: Thompson Dorothy , Etim Nsikak-Abasi  A. , Etim NseAbasi
Published: January 2021

An empirical study was conducted to determine the relationship between higher education and environmental management. Through the multi-stage sampling procedure, the representative sample of 180 respondents were selected for the study. Primary data were obtained with the aid of questionnaire. Data were subjected to univariate probit regression analysis. Results revealed a positive relationship between environmental management and higher education. Findings showed that tertiary education was significant at one percent level suggesting that people who have acquired higher education were more likely to adopt and apply environmental management practices and techniques. Findings further revealed that the variable, no formal education, was negative and significant (P<0.05) indicating that persons without formal education were less likely to imbibe environmental management measures. Supportive policies and institutions which provide access to training and information (awareness and media sensitization) that will expand the opportunities of the poor to invest in environmental improvements are required. Policies to promote sound environmental management and protect the environmental assets through higher education would be a rational decision. The poor with low education must be seen first as part of the solution rather than part of the problem.

We report the discovery of two short-period Saturn-mass planets, one transiting the G subgiant TOI-954 (TIC 44792534, V = 10.343, T = 9.78) observed in TESS sectors 4 and 5 and one transiting the G dwarf K2-329 (EPIC 246193072, V = 12.70, K = 10.67) observed in K2 campaigns 12 and 19. We confirm and characterize these two planets with a variety of ground-based archival and follow-up observations, including photometry, reconnaissance spectroscopy, precise radial velocity, and high-resolution imaging. Combining all available data, we find that TOI-954 b has a radius of

and a mass of

M
J and is in a 3.68 day orbit, while K2-329 b has a radius of

and a mass of

M
J and is in a 12.46 day orbit. As TOI-954 b is 30 times more irradiated than K2-329 b but more or less the same size, these two planets provide an opportunity to test whether irradiation leads to inflation of Saturn-mass planets and contribute to future comparative studies that explore Saturn-mass planets at contrasting points in their lifetimes.
A Cosmic Zevatron Based on Cyclotron Auto-resonance
Authors: Salamin Yousef I. , Wen Meng , Keitel Christoph H.
Published: January 2021

A Zevatron is an accelerator scheme envisaged to accelerate particles to ZeV energies (1 ZeV = 1021 eV). Schemes, most notably the internal shock model, have been proposed to explain the acceleration of ultra-high-energy cosmic-ray particles that have been sporadically detected reaching Earth since 1962. Here, the cyclotron auto-resonance acceleration (CARA) mechanism is tailored and used to demonstrate the possible acceleration of particles ejected as a result of violent astrophysical processes such as the merger of a binary system or a supernova explosion. Such events result in emission of highly energetic particles and ultra-intense beamed radiation. In the simultaneous presence of a super-strong magnetic field, the condition for cyclotron auto-resonance may be met. Thus CARA can act like a booster for particles pre-accelerated inside their progenitor by shock waves, possibly among other means. As examples, it is shown that nuclei of hydrogen, helium, and iron-56, may reach ZeV energies by CARA, under which conditions the particles, while gyrating around the lines of an ultra-strong magnetic field, also surf on the waves of a super-intense radiation field. When radiation-reaction is taken into account, it is shown that the ZeV energy gained by a particle can fall off by less than an order of -magnitude if the resonance condition is missed by roughly less than 20%.
Fundamental Properties of Sheared/Guide Field MHD Magnetic Reconnection
Authors: Nitta 新田 Shin-ya 伸也 , Kondoh 近藤 Koji 光志
Published: January 2021

The properties of the sheared/guide field magnetic reconnection (MRX) are investigated with two-dimensional MHD simulation. We simulate the spontaneous evolution from the isothermal current sheet (CS) equilibrium in which distribution of the thermodynamical quantities is symmetric about the CS. The magnetic shear is characterized by two parameters: the shear parameter and the asymmetry parameter. The asymmetry of the Alfvén speed (V
A0x) perpendicular to the X-line along the CS is essential. We focus on the asymptotic self-similarly expanding phase of the evolution. This research is unique for the discussion based on the consistency across the entire MRX system, although the sheared MRX has been studied since the early 1980s. In addition to reconfirmation of the previously reported properties of the sheared MRX, the following new properties are found. (1) The reconnection jet changes to the “core–envelope structure” (a high-density core with a low-density envelope) for the sheared symmetric V
A0x case but the “two-layered structure” (the high-speed, low-density layer and the medium-speed, high-density layer) for the asymmetric V
A0x case. (2) The parameter dependence of the reconnection rate is clarified. The MRX is fastest for the symmetric case and slows as the asymmetry increases for any fixed shear angle. For the symmetric case, the reconnection rate has a monotonically decreasing dependence on the shear angle. (3) In the asymmetric case, the plasmas from both sides of the CS coexist on the same magnetic field lines in the larger V
A0x side plasmoid. This characteristic structure suggests an efficient plasma mixing when the plasmoid breaks.

Published: January 2021

BACKGROUND: Excess mortality is defined as mortality above what would be expected based on the non-crisis mortality rate in the population of interest.
AIM: In this study, we aimed to access weather the coronavirus disease (COVID)-19 pandemic had impact on the in-hospital mortality during the first 6 months of the year and compare it with the data from the previous years.
METHODS: A retroprospective study was conducted at the University Clinic of Nephrology Skopje, Republic of Macedonia. In-hospital mortality rates were calculated for the first half of the year (01.01–30.06) from 2015 until 2020, as monthly number of dead patients divided by the number of non-elective hospitalized patents in the same period. The excess mortality rate (p-score) was calculated as ratio or percentage of excess deaths relative to expected average deaths: (Observed mortality rate–expected average death rate)/expected average death rate *100%.
RESULTS: The expected (average) overall death mortality rate for the period 2015–2019 was 8.9% and for 2020 was 15.3%. The calculated overall excess mortality in 2020 was 72% (pscore 0.72).
CONCLUSION: In this pragmatic study, we have provided clear evidence of high excess mortality at our nephrology clinic during the 1st months of the COVID-19 pandemic. The delayed referral of patients due to the patient and health care system-related factors might partially explain the excess mortality during pandemic crises. Further analysis is needed to estimate unrecognized probable COVID-19 deaths.
Hypoxia Mesenchymal Stem Cells Accelerate Wound Closure Improvement by Controlling α-smooth Muscle actin Expression in the Full-thickness Animal Model
Authors: Hamra Nur Fitriani , Putra Agung , Tjipta Arya , Amalina Nur Dina , Nasihun Taufiqurrachman
Published: January 2021

BACKGROUND: The active myofibroblast producing extracellular matrix deposition regarding wound closure is characterized by alpha-smooth muscle actin (α-SMA) expression. However, the persistence of α-SMA expression due to prolonged inflammation may trigger scar formation. A new strategy to control α-SMA expression in line with wound closure improvement uses hypoxic mesenchymal stem cells (HMSCs) due to their ability to firmly control inflammation for early initiating cell proliferation, including the regulation of α-SMA expression associated with wound closure acceleration. AIM: This study aimed to explore the role of HMSCs in accelerating the optimum wound closure percentages through controlling the α-SMA expression. MATERIALS AND METHODS: Twenty-four full-thickness rats wound model were randomly divided into four groups: Sham (Sh), Control (C) by NaCl administration only, and two treatment groups by HMSCs at doses of 1.5×106 cells (T1) and HMSCs at doses of 3×106 cells (T2). HMSCs were incubated under hypoxic conditions. The α-SMA expression was analyzed under immunohistochemistry staining assay, and the wound closure percentage was analyzed by ImageJ software. RESULTS: This study showed a significant increase in wound closure percentage in all treatment groups that gradually initiated on days 6 and 9 (p < 0.05). In line with the increase of wound closure percentages on day 9, there was also a significant decrease in α-SMA expression in all treatment groups (p < 0.05), indicating the optimum wound healing has preceded. CONCLUSION: HMSCs have a robust ability to accelerated wound closure improvement to the optimum wound healing by controlling α-SMA expression depending on wound healing phases.
Border interceptions of forest insects established in Australia: intercepted invaders travel early and often
Authors: Nahrung Helen F. , Carnegie Angus J.
Published: January 2021

Invasive forest insects continue to accumulate in Australia (and worldwide) and cause significant impacts through costs of prevention, eradication and management, and through productivity losses and environmental and biodiversity decline. We used our recent non-native Australian forest insect species inventory to analyse border interception rates (2003–2016) of established species, and link interception frequencies with biological traits, historical establishment patterns, commodities and countries of origin. The strongest predictor of interception frequency was year of establishment. Polyphagous species were more likely to be intercepted, as were more concealed species, although this latter likely reflects the higher interceptions of bostrichid borers and other wood-boring Coleoptera relative to other taxa. Interceptions occurred more often for species native to Asia; in contrast, interceptions from other regions were more likely to be of species invasive there. While interception frequencies did not provide a good overall indicator of contemporaneous species establishments, wood and bark borers were more closely linked for establishments and interceptions. The first fifty forest insect species to establish comprised 85% of all border interceptions of established species between 2003 and 2016, while the most-recent fifty species represented just 6% of interceptions. We suggest that early-establishing species are among the “super-invaders” that continue to move globally, while more recent invasive species may be exploiting new trade pathways, new commodity associations, or changes in dynamics in their countries of origin.

Y a-t-il eu un féminisme antifasciste dans l’Espagne des années 1930 ?
Authors: Yusta Rodrigo Mercedes
Published: January 2021

L’alliance entre antifascisme et féminisme a été puissamment réactivée ces dernières années face à la montée en Espagne d’un parti d’extrême droite, VOX, qui a fait de l’antiféminisme un de ses signes d’identité. Les féministes actuelles revendiquent à nouveau, comme ce fut le cas lors du passage à la démocratie en 1975, l’héritage des féministes antifascistes des années 1930. Mercedes Yusta Rodrigo met au jour le caractère en réalité complexe et conflictuel des rapports entre antifascisme et féminisme pour ces militantes engagées dans les années qui vont de la Seconde République au début de la dictature de Franco, afin de retracer la généalogie perdue des féministes antifascistes.
Pourquoi les Clash comptent

Published: January 2021

Au-delà du kitsch et de la pompe du marketing, les Clash ont encore quelque chose à nous apprendre sur l’art en tant que site de lutte. Il n’y a pas que les images de leur performance lors du Carnaval Against Nazis, organisé à Londres en avril 1978 par Rock Against Racism et la Anti-Nazi League. Comme l’écrit Alexander Billet, « l’importance des Clash ne réside pas tant dans leur « génie » que dans leur décision de participer en tant qu’artistes à un monde chaotique et sombre […]. Au-delà de la déflagration sonore surproduite par le marketing, les Clash étaient prêts à plonger tête baissée dans la contradiction et à tirer sur ses points de suture jusqu’à ce qu’ils sautent. »

Authors: Siddiqui H. , Khan S.A. , Saher T. , Siddiqui Z.A.
Published: January 2021

The purpose of the present study was to compare the effect of sciatic nerve mobilisation on muscle flexibility among diabetic and non-diabetic sedentary individuals. The study was a pre-post experimental-group design. A sample of 40 sedentary subjects was assigned into two groups; Group A (diabetics: 10 males and 10 females) and Group B (non-diabetics: 10 males and 10 females). Both groups were tested for hamstring and calf flexibility following which sciatic nerve mobilisation was given to the most affected lower limb in terms of reduced hamstring and calf flexibility. Hamstring flexibility was checked by active knee extension test and calf flexibility was checked with the distance-to-wall technique using a tape measure. It was a two-week program in which subjects were given sciatic nerve mobilisation using sliders technique after which flexibility was checked. Three sessions per week were given for two weeks and muscle flexibility of hamstring and calf was measured after the intervention. The present study findings reveal that sciatic nerve mobilisation by sliders technique when given to diabetic and non-diabetic groups of sedentary individuals for two weeks, enhance patient outcomes in both the groups in terms of increase in hamstring and calf flexibility, but results were more significant in non-diabetic individuals as compared to diabetic individuals. In conclusion, sciatic nerve mobilisation resulted in an increase of muscle flexibility of hamstring and calf muscles in both groups.
Characterization of Di-Rhamnolipid Biosurfactant in Recombinant Escherichia coli
Authors: Kusuma Subhan Hadi , Meitha Karlia , Suhandono Sony
Published: January 2021

Surfactants are amphiphilic molecules, which have hydrophilic and hydrophobic groups. Surfactants have an important role in various fields including agriculture, cosmetics, pharmaceuticals, bioremediation, and the petroleum industry especially EOR but because synthetic surfactants are not biodegradable, it is necessary to produce biodegradable surfactants such as rhamnolipid biosurfactants. Rhamnolipid is a glycolipid biosurfactant produced by Pseudomonas aeuruginosa. This species is a pathogen, so it is needed to overcome this problem by cloning the rhamnolipid gene into Escherichia coli for large-scale production. Rhamnolipid biosynthesis includes three main genes, rhlA, rhlB, and rhlC. The rhlAB produces mono-rhamnolipid and rhlABC produces di-rhamnolipid. The construction involved one plasmid pPM RHLABC (di-rhamnolipid) with T7lac promoter. Characterization of surfactants by E24, IFT, and CMC analysis showed that di-rhamnolipid biosurfactant has the best activity (70%, 0.8 mN/m, and 300 mg/L) than chemical surfactant, sodium dodecyl sulfate (46%, 4.7 mN/m, and 2000 mg/L) at pH 7, 25 °C, and 0% salinity. The conclusion from this research shows that the characteristics of di-rhamnolipid are very promising in the utilization of industrial-scale including EOR technology, agriculture, and pharmacy

Hematite is one of the most stable oxide phases and has been used as a rock-art pigment material in the prehistoric era. Hematite in the form of ochre has been widely used in rock art, burial rites, cosmetics, and decorations on pottery surfaces. Hematite has several hues, ranging from red to black. The variety of hues might arise due to the differences in physicochemical properties of hematite such as crystallinity, crystallite size, morphology, and electronic structure. The differences in physicochemical properties in hematite pigments might be originated from the differences in the pretreatment technique used before application. Herein, we have conducted a thorough study to investigate the evolution of the crystal structure of hematite under various temperatures. We aim to determine the temperature needed to change the hematite color and uncover the transformation of crystallographic properties as a function of sintering temperature. The hematite was synthesized using the precipitation method with Fe (NO3)3.6H2O as a precursor and ammonia (NH4OH) solution as a precipitating agent. The study of the hematite structural evolution was carried out by varying the sintering temperatures from 600 to 900 °C and analyzing the products after sintered using X-ray diffraction technique. The results showed that hematite hue was gradually darkened as the sintering temperature increased as a consequence of higher crystallinity and larger crystallite size of hematite crystal. This study confirms that the origin of color changes in hematite is due to the heating treatment of hematite material.

Selenium is one of the heavy metal pollutants in the aquatic environment. Selenite is a form of inorganic selenium, which is very poisonous to living things. Therefore, we need a method that selectively identify selenite to determine its concentration in water. In this study, a square wave stripping voltammetry was used to measure selenite concentration using copper amalgam working electrode. The optimum measurement parameters were obtained at a deposition potential of –450 mV and a deposition time of 800 seconds. This analysis method had good precision with a relative standard deviation (% RSD) of 4.89%. Linear calibration curves are shown in the range 0.03 mM – 0.10 mM with R2 of 0.988 and in the range of 0.10 mM – 0.70 mM with R2 of 0.995 and a detection limit of 9.0 µM. The standard selenite solution was measured with a recovery percentage of 96.67%. The same solution was measured using the HG-AAS method and the recovery percentage was 96.35%. Statistical tests using the t-test showed that the two results did not have a significant difference with a 95% confidence limit. Thus, the voltammetry method using copper amalgam working electrode can be used as an alternative method for determining selenite, as it is cheaper and simpler than the HG-AAS method.

As a flavonoid, rutin has been found to have a wide range of biological functions, such as resisting inflammation and oxidation, and preventing cerebral hemorrhage and hypertension. It has been found to play an important role in osteoporosis and other orthopedic diseases in recent years. MC3T3-E1 cells were randomly divided into a control group, a rutin-1 group (0.01 mmol/L), a rutin-2 group (0.05 mmol/L) and a rutin-3 group (0.1 mmol/L). Osteogenic differentiation of cells was induced by osteogenic induction fluid. The control group was treated with the maximum dose of drug solvent. 2~3 days later, the solvent was replaced with fresh osteogenic induction fluid containing rutin. After a certain period of routine culture, the cells were collected for subsequent experiments. The expression of Runx2 gene in cells in all groups was detected by Real-time PCR; the expression of Runx2 protein was detected by Western blot and immunocytochemistry; the activity of ALP was detected by reagent kit method; osteogenic differentiation was analyzed by alizarin red staining. The results of Real-time PCR showed that, compared with the control group, the treatment of cells with rutin can significantly increase the expression of Runx2 gene (p<0.05); the higher the concentration, the higher the expression of Runx2 gene, and significant differences were found among groups in which different concentrations were used (p<0.05); the results of Western blot and IHC showed that the expression trend of Runx2 protein in each group was consistent with PCR results. In drug treatment groups, the activity of ALP was significantly higher than that in the control group (p<0.05); there were significant differences among groups in which different concentrations were used (p<0.05). The results of alizarin red staining showed that calcified nodules were formed in all groups and that the area of calcified nodules formed in groups treated with rutin was greater than that in the control group; the greater the concentration, the larger the area. Rutin can promote osteoblastic differentiation; and the greater the concentration, the more effective it is.

Background

Influenza has been shown to increase the risk for severe bacterial infection, in the tropics the seasonality of influenza epidemics is less marked, and this may not be the case. Dengue is often followed by prolonged asthenia and some physicians hypothesized increased susceptibility to infections based on anecdotal observations.

Design and methods

Time series of influenza and dengue surveillance were confronted bacterial sepsis admissions to test the hypotheses. Monthly surveillance data on influenza and dengue and aggregated sepsis data in Cayenne hospital were matched between 24/10/2007 and 27/09/2016. An ARIMA (1,0,1) model was used.

Results

The series of the number of monthly cases of sepsis was positively associated with the monthly number of cases of influenza at time t (β=0.001, p=0.0359). Forecasts were imperfectly correlated with sepsis since influenza is not the only risk factor for sepsis. None of the ARIMA models showed a significant link between the dengue series and the sepsis series.

Conclusions

There was thus no link between dengue epidemics and sepsis, but it was estimated that for every 1,000 cases of flu there was one additional case of sepsis. In this tropical setting, influenza was highly seasonal, and improved vaccination coverage could have benefits on sepsis.

Pulmonary Alveolar Microlithiasis (PAM) is a rare autosomal recessive end stage lung condition characterized by widespread alveolar deposition of calcium microliths. It is worth emphasis india has reported 80 cases out of 1022 cases worldwide but there is no report on lung transplant and and anaesthetic management in this category of patient. This report present the anaesthetic challenge in management of first indian patient with the diagnosis of PAM, who underwent bilateral lung transplantation. Bilateral lung transplantation is one of the most challenging surgeries that require the care of a cardiothoracic anesthesiologist. Utilization of extracorporeal circulation has allowed a safer performance of this procedure in patients with severe cardiopulmonary compromise. Intraoperative management is a pivotal part of the patient's care, as it contributes to the patient's overall outcome.

Published: January 2021

Background:

Pediatric patients are at risk for bleeding after cardiac surgery. Administration of antifibrinolytic agents reduces postoperative blood loss.

Objective:

Evaluation of the efficacy of combined administration of tranexamic acid (TXA) and ethamsylate in the reduction of postoperative blood loss in pediatric cardiac surgery.

Methods:

This prospective randomized study included 126 children submitted for cardiac surgery, and they were allocated into three groups: control group (n = 42); TXA group (n = 42):- received only TXA; and combined ethamsylate TXA group (n = 42):- received a combination of TXA and ethamsylate. The main collected data included sternal closure time, the needs for intraoperative transfusion of blood and its products, the total amount of blood loss, and the amount of the whole blood and its products transfused to the patients in the first 24 postoperative hours.

Results:

Blood loss volume in the first 24 postoperative hours was significantly smaller in combined group than the TXA and control groups and was significantly smaller in the TXA group than the control group. The sternal closure time was significantly shorter in the combined group than the other 2 groups and significantly shorter in TXA than the control group. The amount of whole blood transfused to patients in the combined group during surgery and in the first postoperative 24 h was significantly smaller than the other 2 groups and smaller in TXA group than the control group during surgery.

Conclusion:

Combined administration of ethamsylate and TXA in pediatric cardiac surgery was more effective in reducing postoperative blood loss and whole blood transfusion requirements than the administration of TXA alone.
