A 200 km suspected impact crater Kotuykanskaya near Popigai, Siberia, in the light of new gravity aspects from EIGEN 6C4, and other data
Authors: Klokočník Jaroslav , Kostelecký Jan , Bezděk Aleš , Kletetschka Gunther , Staňková Hana
Published: April 2020

We provide arguments in favour of impact origin of a 200 km suspected impact crater Kotuykanskaya near Popigai, Siberia, Russia. We use the gravity aspects (gravity disturbances, the Marussi tensor of the second derivatives of the disturbing geopotential, the gravity invariants and their specific ratio, the strike angles and the virtual deformations), all derived from the combined static gravity field model EIGEN 6C4, with the ground resolution of about 10 km and a precision of about 10 milliGals. We also use the magnetic anomalies from the model EMAG2 and emphasize the evidence of much deeper sources in the suspected area, constraining the impact origin of this structure.

Konservative Therapie bei hochbetagten Patienten mit terminaler Niereninsuffizienz
Authors: Starke Rebecca
Published: April 2020

Aufgrund der veränderten Alters- und Morbiditätsstruktur der Patienten mit terminalem Nierenversagen rückt die maximale konservative Therapie (KT) zunehmend als mögliche Therapieoption neben der Hämodialyse (HD), Peritonealdialyse (PD) und der Transplantation in den Fokus unserer Betrachtung. Besonders das Dialysepersonal macht die Erfahrung, dass oft hochbetagte, multimorbide Patienten von einer Dialysetherapie hinsichtlich Lebensqualität und Lebenszeit nicht profitieren. Hochbetagte Patienten an der Dialyse sind bzgl. der Pflege ein bedeutender Mehraufwand. Immer wieder kommt es daher zu Differenzen des Betreuungsschlüssels, was zum Ergebnis hat, dass eine zufriedenstellende Behandlung dieser aufwendigen Patienten oft kaum zu gewährleisten ist. Die maximale KT ist in vielen Bereichen der Nephrologie unterrepräsentiert und wird noch zu wenig in die Entscheidungsfindung nach einer adäquaten Therapie für den alten Patienten einbezogen. Im Nephrologicum Lausitz ist die konservative Therapie seit 2013 eine integrierte Therapieform der terminalen Niereninsuffizienz. Eine Analyse des Ist-Zustandes im Januar 2019 zeigt, dass ca. 50 % von 42 erfassten Patienten ein Alter von über 90 Jahren aufwiesen. Im Vordergrund der Komorbiditäten stehen Herzerkrankungen (77 %), Diabetes mellitus (57 %) und pAVK (25 %). Mittels der maximalen KT konnte bei 36 von 42 Patienten die Nierenfunktion stabilisiert oder verbessert werden und die Folgesymptome des terminalen Nierenversagens bei ca. 80 % durch entsprechende medikamentöse Therapiemaßnahmen kompensiert werden. Die Betreuung der KT-Patienten durch eine „KT-Schwester“ ist besonders anspruchsvoll und erfordert viel Zeit, Erfahrung und Einfühlungsvermögen. Sie unterscheidet sich in der Arbeit einer normalen Sprechstundenschwester erheblich. Eine große Rolle spielt dabei v. a. die gute Zusammenarbeit zwischen dem Nephrologen, den Angehörigen, Hausärzten und den Pflegediensten. Trotz des pflegerischen Mehraufwandes entschädigt das Mehr an Lebensqualität und die Zufriedenheit der alten, multimorbiden Patienten in erheblichem Maße, da Betreuungsschlüssel und Ergebnis (Lebensqualität der Patienten) in einem zufriedenstellenderen Verhältnis stehen. Mehr als 50 % der Patienten weisen eine Lebenszeit mit konservativer Therapie von über 3 Jahren in überwiegend gutem Ernährungszustand und hoher Patientenzufriedenheit auf – trotz stark reduzierter und eingeschränkter Mobilität sowie Gebrechlichkeit. Die jährliche Mortalitätsrate liegt bei 25–30 % und ist vergleichbar mit der jährlichen Sterberate bei hochbetagten Dialysepatienten. Aufgrund von Erfahrungen im Nephrologicum Lausitz und aus veröffentlichten Studienergebnissen ist die maximale KT eine berechtigte Therapieoption des terminalen Nierenversagens und sollte bei der Entscheidungsfindung zu einer adäquaten Therapie bei hochbetagten, multimorbiden und gebrechlichen Patienten einen höheren Stellenwert als bisher einnehmen.

Effect of Health Education on Women’s Knowledge Level about Pap Smear’s Early Detection of Cervical Cancer Prevention
Authors: Simanullang Rostime Hermayerni , Sitopu Selli Dosrina
Published: April 2020

Cervical cancer is a scary disease for women all over the world. This disease can actually be prevented and identified early. Pap smear is one of the tools of early detection to determine the presence of symptoms of cervical cancer. If women’s knowledge is good about pap smear’s early detection of cervical cancer, it can prevent the disease. The objective of this study was to know the effect of health education in women about pap smear which aids in early detection and prevention of cervical cancer. This was a quasi-experimental one group pretest, conducted without a control group at Murni Teguh Memorial Hospital (MTMH), Medan, North Sumatra from June to July 2018. There were 36 samples selected using purposive sampling. Wilcoxon signed-rank test was used for data analysis. The results of this study showed that there was a difference in the mean value of women's knowledge levels (p = 0. 000) before and after the intervention. The conclusion of this study was that there was a significant effect of health education in terms of an increase in the level of women's knowledge about pap smear’s early detection and prevention of cervical cancer. It is expected that health education about pap smear’s early detection and prevention of cervical cancer will prove to be very important in the future.

Authors: Spencer Elizabeth A , Kinnucan Jami , Wang Julie , Dubinsky Marla C
Published: April 2020

Background

Ustekinumab is approved for Crohn’s disease and Ulcerative colitis with acute infusion reactions reported at a rate of 0.9%–4.5%.

Methods

A retrospective chart review was conducted on inflammatory bowel disease (IBD) patients experiencing an acute infusion reaction to ustekinumab at 2 large institutions.

Results

Acute ustekinumab infusion reactions occurred in 16 patients with Crohn’s disease (CD) and Ulcerative colitis (UC), at a rate of 0.8%–3%. Patients were all naïve to ustekinumab, receiving their initial IV induction. Ninety-three percent subsequently tolerated the injection without issues.

Conclusions

In this large, real-world study of acute infusion reactions to ustekinumab, the rate was similar to that seen in clinical trials—0.8%–3%.
Overlap matrix concentration in optimal Bayesian inference
Authors: Barbier Jean
Published: April 2020

We consider models of Bayesian inference of signals with vectorial components of finite dimensionality. We show that under a proper perturbation, these models are replica symmetric in the sense that the overlap matrix concentrates. The overlap matrix is the order parameter in these models and is directly related to error metrics such as minimum mean-square errors. Our proof is valid in the optimal Bayesian inference setting. This means that it relies on the assumption that the model and all its hyper-parameters are known so that the posterior distribution can be written exactly. Examples of important problems in high-dimensional inference and learning to which our results apply are low-rank tensor factorization, the committee machine neural network with a finite number of hidden neurons in the teacher–student scenario or multi-layer versions of the generalized linear model.

Authors: Phan Khiem Hong , Tran Dzung Tri
Published: April 2020

In this paper, new analytic formulas for one-loop contributing to Higgs decay channel $H \rightarrow Z\gamma$ are presented in terms of hypergeometric functions. The calculations are performed by following the technique for tensor one-loop reduction developed in [A. I. Davydychev, Phys. Lett. B 263 (1991) 107]. For the first time, one-loop form factors for the decay process are shown which are valid at arbitrary space–time dimension $d$.
ORGAN ABSORBED DOSE ESTIMATION REFLECTING SPECIFIC ORGAN MASSES WITH SIMPLE SCALING OF REFERENCE DOSES USING THE ORGAN MASSES
Authors: Manabe Kentaro , Koyama Shuji
Published: April 2020

Estimating organ absorbed doses in consideration of person-specific parameters is important for radiation protection in diagnostic nuclear medicine. This study proposes a straightforward method for estimating the organ dose that reflects a specific organ mass by scaling the reference organ dose using the inverse ratio of the specific organ mass to the reference organ mass. For the administration of radiopharmaceuticals labelled by 99mTc or 123I, the organ doses for the liver, spleen, red marrow and thyroid obtained by the method were compared with those generated by a Monte Carlo simulation. The discrepancies were less than 14% for the liver, spleen and thyroid. Conversely, in some cases, the red marrow discrepancies were greater than 30% due to the wide distribution of red marrow in the trunk and head regions. This study confirms that the method of scaling organ doses can be effective for estimating mass-specific doses for solid organs.
Educational needs and psychoeducation interventions in clozapine users: a narrative review
Authors: Verdoux H. , Quiles C.
Published: April 2020

Objective

Increasing users' knowledge about the expected benefits and risks of clozapine may contribute to the initiation and maintenance of clozapine in persons with treatment‐resistant schizophrenia (TRS). The objective was to identify the educational needs of clozapine users and the interventions aimed at addressing these needs.

Method

We systematically searched multiple electronic databases for articles: (i) exploring educational needs of clozapine users and of their relatives; and (ii) reporting educational interventions aimed at addressing these needs. Data were synthesized narratively.

Results

A total of 30 articles published from 1990 to 2019 in 8 countries fulfilled our inclusion criteria. As most studies on educational needs (n = 18) were carried out in persons already taking clozapine, educational needs of TRS patients who were candidates for clozapine treatment are not well documented. Users’ level of knowledge about clozapine was often poor, especially about adverse effects or interactions with other substances, with a poor retention of information delivered at treatment initiation. Among 12 studies reporting educational interventions in clozapine users, five provided quantitative outcomes. Their findings suggest that structured educational programmes may contribute to promote clozapine initiation and to improve users' knowledge about this drug.

Conclusion

The literature is sparse on structured educational interventions about clozapine, and only one randomized controlled trial was identified. A promising strategy emerging from this review may be staging educational interventions according to the evolving needs of persons with TRS before clozapine use, at initiation and during maintenance treatment.
Home thoughts of abroad: Ohthere’s Voyage in its Anglo‐Saxon context
Authors: Allport Ben
Published: April 2020

The Old English text known as Ohthere’s Voyage is regarded as a key source for Norwegian history. Consequently, the context of its composition and inclusion in the Old English Orosius has often been overlooked. This article demonstrates that the text cannot be separated from the processes that shaped it during its early transmission. Continental geographical traditions of the peoples of the north governed the preconceptions of Ohthere’s audience. Furthermore, the individual who included the account in the Orosius edited the latter text to anticipate it and tailored the sailor’s account to support the West Saxon ideological underpinnings of its new context.

Published: April 2020

Immune responses against enterotoxigenicEscherichia coli(ETEC) were examined in Bangladeshi adults with naturally acquired disease and compared to responses in age-matched Bangladeshi volunteers who had been orally immunized with a vaccine consisting of inactivated ETEC bacteria expressing different colonization factor antigens (CFs) and the B subunit of cholera toxin. B-cell responses in duodenal biopsy samples, feces, intestinal washings, and blood were determined. Because most of the patients included in the study were infected with ETEC expressing CS5, immune responses to this CF were studied most extensively. Vaccinees and patients had comparable B-cell responses against this antigen in the duodenum: the median numbers of antibody-secreting cells (ASC) were 3,300 immunoglobulin A (IgA) ASC/107mononuclear cells (MNC) in the patient group (n= 8) and 1,200 IgA ASC/107MNC in the vaccinees (n= 13) (not a significant difference). Similarly, no statistically significant differences were seen in the levels of duodenal B cells directed against enterotoxin among vaccinees and patients. A comparison of the capacities of the various methods used to assess mucosal immune responses revealed a correlation between numbers of circulating B cells and antibody levels in saponin extracts of duodenal biopsy samples (r= 0.58;n= 13;P= 0.04) after vaccination. However, no correlation was seen between blood IgA ASC and duodenal IgA ASC after two doses of vaccine. Still, a correlation between numbers of CF-specific B cells in blood sampled from patients early during infection and numbers of duodenal B cells collected 1 week later was apparent (r= 0.70;n= 10;P= 0.03).
Effect of MALP-2, a Lipopeptide from
Mycoplasma fermentans
, on Bone Resorption In Vitro

Published: April 2020

Mycoplasmas may be associated with rheumatoid arthritis in various animal hosts. In humans, mycoplasma arthritis has been recorded in association with hypogammaglobulinemia.
Mycoplasma fermentans
is one mycoplasma species considered to be involved in causing arthritis. To clarify which mycoplasmal compounds contribute to the inflammatory, bone-destructive processes in arthritis, we used a well-defined lipopeptide, 2-kDa macrophage-activating lipopeptide (MALP-2) from
M. fermentans
, as an example of a class of macrophage-activating compounds ubiquitous in mycoplasmas, to study its effects on bone resorption. MALP-2 stimulated osteoclast-mediated bone resorption in murine calvaria cultures, with a maximal effect at around 2 nM. Anti-inflammatory drugs inhibited MALP-2-mediated bone resorption by about 30%. This finding suggests that MALP-2 stimulates bone resorption partially by stimulating the formation of prostaglandins. Since interleukin-6 (IL-6) stimulates bone resorption, we investigated IL-6 production in cultured calvaria. MALP-2 stimulated the liberation of IL-6, while no tumor necrosis factor was detectable. Additionally, MALP-2 stimulated low levels of NO in calvaria cultures, an effect which was strongly increased in the presence of gamma interferon, causing an inhibition of bone resorption. MALP-2 stimulated the bone-resorbing activity of osteoclasts isolated from long bones of newborn rats and cultured on dentine slices without affecting their number. In bone marrow cultures, MALP-2 inhibited the formation of osteoclasts. It appears that MALP-2 has two opposing effects: it increases the bone resorption in bone tissue by stimulation of mature osteoclasts but inhibits the formation of new ones.
Role of Nitric Oxide in the Enhancement of Pentylenetetrazole-Induced Seizures Caused byShigella dysenteriae

Published: April 2020

Convulsions and encephalopathy are frequent complications of childhood shigellosis. We studied the role of nitric oxide (NO) inShigella-related seizures in an animal model. Pretreatment of mice withShigella dysenteriae60R sonicate elevated serum NO levels and enhanced the convulsive response to pentylenetetrazole (PTZ), as indicated by a higher mean convulsion score and a higher number of mice responding with seizures. Treatment of the mice withS-methylisothiourea sulfate (SMT), a potent inhibitor of inducible NO synthase (NOS), prevented the elevation of serum NO levels and concomitantly reduced the enhanced response to PTZ. The mean convulsion scores were 0.7, 0.7, 1.3, and 0.8 for mice treated with saline, saline and SMT,S. dysenteriae60R sonicate, andS. dysenteriae60R sonicate with SMT, respectively (P= 0.001 for 60R sonicate versus saline andP= 0.013 for 60R sonicate versus 60R sonicate with SMT). The corresponding seizure rates were 40, 44, 75, and 47% for saline, saline with SMT,S. dysenteriae60R sonicate, andS. dysenteriae60R sonicate with SMT, respectively (P= 0.0004 for 60R sonicate versus saline andP= 0.005 for 60R sonicate versus 60R sonicate with SMT). In contrast, injection ofN-nitro-l-arginine, a selective inhibitor of constitutive NOS, neither abolished the elevation of serum NO nor attenuated the enhancement of seizures. These findings indicate that NO, induced byS. dysenteriae60R sonicate, is involved in enhancing the susceptibility to seizures caused byS. dysenteriae.
Cytokine Control of the Granulomatous Response inSchistosoma mansoni-Infected Baboons: Role of Exposure and Treatment

Published: April 2020

Variations in exposure and treatment may contribute to heterogeneity in immunity and granuloma-induced pathology in human schistosomiasis. To examine this hypothesis, olive baboons were either repeatedly infected withSchistosoma mansonicercariae or received an equivalent dose in a single infection. They were then cured with praziquantel and reinfected with a single exposure. Serial liver biopsies were obtained throughout the course of the experiment, and cytokine responses by peripheral blood mononuclear cells were measured every 2 to 3 weeks. Reinfection after treatment resulted in a twofold-smaller granuloma size at 6 and 9 weeks after infection compared to the size for the same period after primary infection (P< 0.001) but had no effect at 16 or 19 weeks postinfection. The pattern of exposure did not influence granuloma size. During primary infection schistosome-soluble egg antigen (SEA)-induced cytokine production correlated with granulomatous inflammation. Cytokine levels peaked during the acute infection, declined with chronic infection, and became undetectable after treatment. Reinfection after treatment stimulated a two- to three-fold increase in SEA-specific interleukin-4 (IL-4), IL-5, IL-10, IL-2, and transforming growth factor β (TGF-β) production and a marked rise in SEA-specific immunoglobulin E (IgE) and IgG regardless of the type of exposure. Cytokine production was significantly greater in repeatedly exposed animals (P< 0.001). SEA-induced gamma interferon production, however, did not increase with reinfection after treatment. SEA-induced TGF-β was the only cytokine that remained elevated as the infection become chronic and correlated with diminished hepatic granuloma size, implying its participation in down-modulation. These studies demonstrate that baboons partially retain their ability to down-modulate the granulomatous response after treatment.

circKIF4A promotes tumorogenesis of glioma by targeting miR-139-3p to activate Wnt5a signaling
Authors: Huo Long-Wei , Wang Ya-Fei , Bai Xiao-Bin , Zheng Hu-Lin , Wang Mao-De
Published: April 2020

Background

Glioma has the characteristics of high incidence and mortality, and is a common malignant tumor of the central nervous system. Circular RNAs (circRNAs) have been reported to play vital roles in progression of cancer including glioma, and circKIF4A is up-regulated in glioma tissues. However, its role and mechanisms in gliomas are unclear.

Methods

circKIF4A and miR-139-3p were determined by qRT-PCR. Transwell assay, wound-healing assay, cell colony formation and flow cytometry were performed to measure cell invasion, migration, proliferation and apoptosis. Western blotting was used to evaluate Wnt/β-catenin pathway-related protein. Luciferase reporter assays confirmed the relationship among circKIF4A, miR-139-3p and Wnt5a. Sphere formation was performed to measure the ability of glioma-initiating cells (GICs) spheroid formation. A nude mouse xenograft model was established and immunohistochemical staining was used to detect Ki-67 and Wnt5a levels.

Results

circKIF4A and Wnt5a were up-regulated and miR-139-3p was down-regulated in both glioma cells and tissues. circKIF4A promoted Wnt5a expression by sponging miR-139-3p. Knockdown of circKIF4A inhibited the colony formation ability, migration and invasion, and promoted the apoptosis of glioma cells by regulating miR-139-3p. Knockdown of circKIF4A inhibited Wnt/β-catenin signaling pathway and proliferation-related signal via miR-139-3p. Furthermore, knockdown of circKIF4A or overexpression of miR-139 suppressed the ability of sphere formation of GICs and inhibitd Wnt/β-catenin signaling pathway and proliferation-related signal in GICs. Additionally, depletion of circKIF4A decreased the expression level of Wnt5a and Ki-67, inhibited tumorigenesis in xenograft modes.

Conclusion

circKIF4A was overexpressed in glioma, and knockdown of circKIF4A suppressed glioma progression via miR-139-3p/Wnt5a axis. The results indicated that circKIF4A may be a potential target for clinical treatment of glioma.
IncobotulinumtoxinA for the treatment of spasticity in children with cerebral palsy – a retrospective case series focusing on dosing and tolerability
Authors: León-Valenzuela Angel , Palacios Juan Sánchez , del Pino Algarrada Rogelio
Published: April 2020

Background

IncobotulinumtoxinA (Xeomin®) is a botulinum neurotoxin type A with established efficacy in the treatment of upper-limb spasticity in adults. This retrospective case series in a university hospital setting aimed to elucidate the safety and tolerability of incobotulinumtoxinA for treatment of spasticity in children with cerebral palsy.

Methods

Participants received incobotulinumtoxinA injections up to a maximum total dose of 600 U, 24 U/kg body weight. Medical records were reviewed for key demographic information, incobotulinumtoxinA exposure, and adverse effects (AEs).

Results

Sixty-nine children were included (mean age [SD], 8.3 [3.9] years; 44/69 [63.8%] male). One-hundred-and-ninety-one injections were administered, with mean (SD) of 2.8 (1.5) treatment cycles/participant and dosing interval of 6.0 (1.7) months. The number of muscles injected increased from 2.4 (1.2) at cycle 1 to 4.2 (1.9) at cycle 6. The mean (SD) total incobotulinumtoxinA dose increased from 191.7 (126.2) U, (8.5 [5.4] U/kg body weight) at cycle 1 to 368.0 (170.1) U, (9.9 [5.5] U/kg body weight) at cycle 6. Seventy four adverse effects (37.5% of injections) were reported, the most frequent was injection pain (93.2% of AEs). Only three AEs were considered directly treatment-related by injectors: muscle weakness, generalized weakness, and fever.

Conclusions

Our clinical experience indicates that incobotulinumtoxinA is a well-tolerated treatment option for focal spasticity in children with cerebral palsy.

Trial registration

As the study was observational and retrospective, no EudraCT registration number was requested. The internal code assigned to the study in the administrative resolution was: 1143-N-15.

The endophytic fungus, Beauveria bassiana has been found to occur endophytically in hundreds of plant species tissues and has been inoculated for establishment in different plants. It has negative effect on piercing-sucking insects in grapevine plants. Thus, the present study aimed to detect the endophytic fungus, B. bassiana throughout ITS genes analysis in the grapevine plant, Vitis venifera cv. Taify and assess its potential for controlling the grapevine aphid, Aphis illinoisensis Shimer (Hemiptera: Aphididae). The obtained 5 isolates were DNA sequenced for ITS region. Data analysis showed that there were 2 different isolates (accession number: MN900613 for isolate Bb-Taif1 and MN900614 for isolate Bb-Taif2). The values of LC50 were 6.041 × 104, 3.199 × 105 spores/ml while those of LC90 were 6.13 × 106 and 7.474 × 107 spores/ml after 3 days of treatment by Bb-Taif1 and Bb-Taif2, respectively. These values showed that the virulence of Bb-Taif1 isolate was higher in its efficacy than the Bb-Taif2 isolate. Further investigations are needed to evaluate its efficacy on other piercing sucking or chewing insect pests throughout conidia spraying, soil inoculation, and/or root immersion for grapevine plants.

Potato, one of the most important food crops in the world, is susceptible to viruses, which reduce its yield and production efficiency. The resistance of potatoes to viral infection is an essential factor in the preservation of the variety’s productive qualities. In addition, there are several ways of selection for recovering and obtaining the initial seed material that is free from viruses for further reproduction in the seed growing of potatoes. It should be noted that in the literature the issues of medium-late potato varieties resistance to viral diseases in the Forest-Steppe zone of Ukraine are not fully covered, which has become the subject of our research. In our studies we used the material obtained by the method of improving selections, as well as using thermotherapy and apical meristem culture. Over the years of reproduction both meristematic and seed material from improving selections, the virus infestation in plants wasn’t changed significantly, provided that all seed growing events were observed. It has been proven that the yield of super-super-elite of Lybid variety is not significantly changed depending on the method of obtaining the initial material. The variety Gorlitsa has higher yield in the plantations formed by clonal propagation. It has been established that the yield of variety Lybid super-elite varies, but not significantly, depending on the method of obtaining the initial material. The variety Gorlitsa has a higher super-elite yield when using the initial material from clonal propagation in breeding nurseries with use of improved selections. Significant influence on the manifestation of the sign, both in the cultivation of super-super-elites and super-elites, has the weather conditions of the year and the biological characteristics of the variety. In 2017, the highest yield of tubers was obtained at Gorlitsa – 3.74·104 kg ha-1, at Lybid the lower yield was 2.43·104 kg ha-1. In 2018, the highest yield of tubers was formed by Lybid variety – 3.50·104 kg ha-1, and the lowest was byt Gorlitsa variety – 2.56·104 kg ha-1.

To maintain a stable composition of the gastrointestinal tract microflora in farm animals it is necessary to use probiotic agents to ensure the full functioning of the digestive, hormonal, and immune systems of the body. Most modern probiotics include lactic acid bacteria and bifidobacteria, which are the most physiologically valuable components of a healthy organism’s an indigenous microflora. The aim of this study was to provide indication and identification from the milk of healthy cows and gastric tract of healthy pigs and calves of the genus bacteria Lactobacillus, Bifidobacterium, and Lactococcus. The objects of research were cultures of microorganisms isolated from cows milk (82), the gastrointestinal tract of cattle (317), and piglets of different age groups (114). Bacteriological studies were carried out on the basis of the veterinary sanitation and parasitology laboratory of the National Scientific Center "Institute of Experimental and Clinical Veterinary Medicine" (Kharkiv) in accordance with current regulatory documents. According to the research of the gastrointestinal tract of clinically healthy calves and piglets isolated and typified to 317 and 114 cultures of microorganisms, the species composition of the microflora (82 bacterial cultures) of the cisternous and parenchymatous milk of clinically healthy cows was determined. A total of 513 isolates of microorganisms were isolated, including: Enterobacter spp. –2 (0,39%), Staphylococcus spp. – 7 (1,37%), Bacillus spp. – 11 (2,14%), Enterococcus spp. – 33 (6.43%), Lactococcus spp. – 75(14,62%), Bifidоbacterium spp. – 170 (33,14%), and Lactobacillus spp. – 215 (41,91%). In the study of the biological properties of isolated microorganisms Lactobacillus spp. (215) established their species identity: L. brevis – 7 (3.26%), L. delbrueckii – 9 (4,19%), L. acidophilus – 21 (9,77%), L. fermentum – 23 (10,69%), L. casei – 57 (26,51%), and L. plantarum – 98 (45.58%). Cultures of Bifidobacterium spp. (170) belong to B. suis – 2 (1,18%), B. breve – 7 (4,12%), B. lactentis – 15 (8,82%), B. bifidum – 21 (12,35%), B. longum – 22 (12,94%), B. infantis – 25 (14,71%), and B. adolescentis – 78 (45,88%).

Uma escutadeira que conta: a memória como construtora de identidade e potencializadora da escrita em Meus Desacontecimentos, de Eliane Brum
Authors: Da Costa Karine Conte de Mattos
Published: April 2020

O presente artigo tem por objetivo analisar como a autoficção na obra Meus Desacontecimentos, de Eliane Brum, torna-se fundamental na formação e afirmação da identidade da autora como, antes de tudo, escritora. Desta forma, analisa-se o papel tendencioso, precursor e libertário da escrita nas memórias da narradora e a importância disso para lidar com a própria história e superar medos e traumas. Para compreender o papel da recordação dentro do processo identitário, recorre-se aos conceitos já abordados por Paul Ricoeur (2007), Aleida Assmann (2011), Laura Reestrepo (2008), dentre outros. Sendo assim, entende-se que, na obra em análise, a infância é recriada tal qual um palco onde a vida é encenada e seleciona o elenco de influência que deseja reforçar, bem como salienta o protagonismo dado ao ato da escrita dentro do passado e do presente.
Mulheres e literatura: vozes de reconhecimento, transgressão e identidade
Authors: Atienzo Daniela Rebeca Campos , De Godoy Maria Carolina
Published: April 2020

O interesse deste artigo é tratar de vozes de escritoras negras que representam sua condição tanto no plano individual quanto coletivo. Para tanto, a proposta é estudar a poesia da brasileira contemporânea Cristiane Sobral e o poema “Me gritaron Negra”, da peruana Victoria Santa Cruz (1923-2014), a fim de compará-las quanto ao modo de reconhecerem-se negras e às suas afirmações identitárias no campo literário, por meio da representação de múltiplas vozes e as raízes ancestrais. Para a discussão teórica e crítica, centraremos em Deleuze (1977), Bernd (1988), Spivak (1988); e Hall (2005). É importante ressaltar como a identidade é construída a partir do olhar do Outro em debate com o próprio sistema de pensamento, por conseguinte constataremos como as conexões que se estabelecem entre as múltiplas vozes presentes nos poemas reafirmam suas raízes ancestrais e de “identificação” vistas como “um processo em andamento” (HALL, 2006), e não como uma obra acabada e fixa.
Isabel Allende e Marcela Serrano: vozes chilenas na literatura latino-americana
Authors: Zinani Cecil Jeanine Albert
Published: April 2020

Este artigo tem como objetivo examinar elaborações de gênero, como categorias do feminino, no conto “Duas palavras”, de Isabel Allende, e no romance Nossa Senhora da Solidão, de Marcela Serrano. Procedeu-se a uma revisão de conceitos de crítica feminista aplicados aos textos, enfatizando a questão da linguagem como eixo norteador. Verificou-se a pertinência do exame da especificidade da escritura e da leitura como modalidades de permanência da história da comunidade, no caso do conto, e a chave para decifrar o enigma, no caso do romance. Também é importante constatar a relevância dessas atividades, na medida em que operam tanto na constituição da identidade quanto na emancipação do sujeito feminino.
Una noción poética de la patria mexicana: Esther Tapia de Castellanos y la poesía nacionalista del siglo XIX
Authors: Medina Gabriela Sánchez , López Ariadna Alvarado
Published: April 2020

La obra poética de Esther Tapia de Castellanos es pieza clave para la comprensión de dos fenómenos culturales fundamentales en el proceso de construcción del proyecto nacional de los liberales mexicanos; desde la perspectiva del uso político de la literatura, contribuye a la configuración de un/otro sentido de Patria, pues sus poemas proponen imágenes femeninas que dotan de rostro y sentimiento a la idea de nación que procuraba asentarse por aquellos años; desde la representación puramente literaria, su poesía está llena de retratos del deber ser de la mujer mexicana. En la comunión de ambos aspectos la poesía de Esther Tapia es, al mismo tiempo, un ejercicio de aceptación de los roles tradicionalmente impuestos a la mujer y un acto subversivo en contra de éstos, si consideramos que la incursión de las mujeres en el ámbito de la creación literaria rebasa los límites del espacio cerrado e íntimo del hogar y se apropia de los escenarios públicos reservados al varón. En este trabajo proponemos un acercamiento a algunos poemas de Esther Tapia que se publicaron en la prensa del siglo XIX. Tomamos como punto de partida la noción de Patria para analizar, a partir de los mecanismos poéticos empleados, la forma en que se refracta el sujeto femenino en los textos de esta autora.***Uma noção poética da pátria mexicana: Esther Tapia de Castellanos e a poesia nacionalista do século XIX***O trabalho poético de Esther Tapia de Castellanos é fundamental para entender os fenômenos culturais fundamentais no processo de construção do projeto nacional dos liberais mexicanos; do ponto de vista do uso político da literatura, contribuindo para a configuração de outro sentido do país, seus poemas propõem imagens femininas que dançam e sentem a ideia de uma nação que procurou se sentar durante aqueles anos atrás; a partir da representação puramente literária, sua poesia é repleta de retratos do ser da mulher mexicana. Na comunhão de ambos os aspectos, a poesia de Esther Tapia é, ao mesmo tempo, um exercício de aceitação dos papéis tradicionalmente impostos às mulheres e um ato subversivo contra eles, se considerarmos que a incursão das mulheres no campo da a criação literária ultrapassa os limites do espaço íntimo e fechado do lar e se apropria dos cenários públicos reservados aos homens.

A ditadura militar brasileira e os romances As meninas e As horas nuas, de Lygia Fagundes Telles
Authors: Santos João Pedro Rodrigues
Published: April 2020

No presente artigo apresentamos uma reflexão sobre o processo de representação de eventos históricos de censura, barbárie e tortura evidenciados nos romances As meninas e As horas nuas, da escritora brasileira Lygia Fagundes Telles. Nossa pesquisa, que teve como arcabouço teórico os pressupostos de Paul Ricoeur, aponta que a literatura e a história experimentam de forma geral, e em especial nessas obras analisadas, uma intensa simbiose. Em síntese, há história na literatura e há literatura na história. Essa troca mostra-se enriquecedora para ambas as disciplinas. Sobretudo, nos dias de hoje, torna-se cada vez mais necessário (re)lembrar os horrores praticados na ditadura militar brasileira.

La escritura de Clorinda Matto y Laura Riesco: Un siglo de literatura femenina
Authors: Guardia Sara Beatriz
Published: April 2020

La escritura femenina se inició en el Perú durante el período colonial entre los siglos XVII y XVIII, circunscrita a los conventos y conformada por cartas, documentos jurídicos, testimonios, poesía, y una escritura autobiográfica propiciada por los confesores. A finales del siglo XIX surgió un importante movimiento de mujeres que incursionaron en la literatura; seguidas después por la vanguardia literaria y artística de la década del veinte; y de las contemporáneas. Voces que han emergido de una larga lucha que tuvieron que librar las mujeres para imponerse en una sociedad que les negaba el derecho de incursionar en aquello que siempre había sido reservado a los hombres: la literatura. En el presente artículo estudiamos dos novelas escritas con un siglo de diferencia: Aves sin nido de Clorinda Matto de Turner, publicada en 1889, y Ximena de dos caminos, de Laura Riesco, en 1994.***Os escritos de Clorinda Matto e Laura Riesco: Um século de literatura feminina***A escrita feminina começou no Peru durante o período colonial entre os séculos XVII e XVIII, circunscrita a conventos e composta de cartas, documentos legais, testemunhos, poesia e uma escrita autobiográfica propiciada pelos confessores.

Authors: Sunaengsih Cucun , Komariah Aan , Isrokatun Isrokatun , Anggarani Mayang , Silfiani Sindy
Published: April 2020

This research aims at illustrating the implementation of Professional Learning Community (PLC) programs, which later will be used to be the basic data for the preparation of PLC program design that is applicable and easily implemented by the teachers. The low contribution and discontinuity of teachers in the PLC programs in primary schools have impacted on the lack of optimization of the PLC programs as a support for sustained improvement of teacher professionalism. This research employed a descriptive research design with a survey approach involving 52 primary school teachers in Sumerdang Regency. The research results revealed that even though the teachers’ understanding of the PLC program objectives was very high, the teachers’ understanding of the PLC program mechanism was still low. Thus, this resulted in the low level of the implementation of the PLC program in primary schools, both in programs and regulations. Therefore, further research is expected to produce the operational, structured, and applicable PLC programs in order to increase the teachers’ participation in implementing the PLC programs for improving teacher professionalism, and having a real impact on the improvement of the quality of learning in primary schools.
