Authors: Mendonça Neto Octavio Ribeiro de , Vieira Almir Martins , Oyadomari José Carlos Tiomatsu
Published: January 2019

A falta de sintonia entre a pesquisa acadêmica e as necessidades dos práticos na área de contabilidade e gestão (rigor-relevance gap) é fato conhecido e que vem sendo discutido na academia. O presente ensaio tem por objetivo contribuir para a discussão do papel dos mestrados profissionais na mitigação deste problema (rigor-relevance gap), ao discutir as principais razões para a falta de alinhamento entre a pesquisa acadêmica e a prática profissional, ou seja, a resistência na incorporação da técnica pela cultura e resistência da academia na aceitação de paradigmas de pesquisas alternativos. Propõe a utilização da pesquisa intervencionista como uma metodologia de pesquisa alternativa a ser utilizada pelos mestrados profissionais na solução de problemas práticos e criação de conhecimento, sugerindo que, para que diminuição do rigor-relevance gap, alguns passos precisam ser dados, o que inclui aperfeiçoamento dos critérios de avaliação da CAPES, além da aceitação, por parte da academia, de paradigmas de pesquisas alternativos e ampliação do espaço para a divulgação da produção dos mestrados profissionais.

Chemokines and their receptors have been proposed to play important roles in tumor progression and metastasis. To investigate their roles in the progression of primary and metastatic malignant liver tumors and their prognosis, we compared expression profiles of CXCL12/CXCR4, CCL20/CCR6, and CCL21/CCR7 in hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM). Immunohistochemistry was used to analyze the expression levels of the chemokine/chemokine receptor pairs in 29 HCC and 11 CRLM specimens and adjacent non-cancerous tissues, and correlations with clinicopathological variables and overall survival were determined. CCL20/CCR6 expression was higher in HCC than in adjacent non-cancerous tissues. High CCR6 expression in HCC was negatively associated with 5-year survival rate and was an independent prognostic factor for overall survival of HCC patients, whereas differences were not observed between CRLM and adjacent tissues. Furthermore, significantly higher expression of CCL21/CCR7 was found in CRLM than in HCC. In summary, the CCL20/CCR6 axis was elevated in HCC but not in CRLM, whereas the CCL21/CCR7 axis was elevated in CRLM but not in HCC.

Published: January 2019

Background:Honey has positive effects on wound healing due to its properties to decrease inflammatory reaction, assist wound debridement, lessen wound odor, help moisturize the wound, promote wound healing and has antibacterial effect. In this research we try to confirm the benefit of using Indonesian local honey by comparing its efficacy with Manuka honey, which is already known yet still costly and not readily available in Indonesia.Methods: Two kinds of honey above were compared for its physical and chemical properties of antibacterial effects and safety, its acidity (pH) using pH meter, osmotic pressure with indirect measurement using hygroscope and hydrogen peroxide concentration using hydrogen peroxide strip test, also for its bacterial contents using standardized microbiological culture.Results: The measurements of the water activity, pH level,production of hydrogen peroxide, also the bacterial content, showed that there is no significant difference between the manuka honey and the local ones.Discussion: Both of the honey pH levels are still within the normal range of honey pH level (3.5-4.5) which still have the antibacterial properties to inhibit bacterial growth. Both of the honey water activity level are still within the normal range of honey water activity level (0.500–0.650) which still have the antibacterial properties to inhibit bacterial growth. Manuka honey has been known as non peroxide honey that didn’t produce any hydrogen peroxide.Conclusion:Indonesian local honey which has been used in this research has a similar physical–chemical characteristic as Manuka honey; making it a very good alternative source of medicinal honey because of its affordability and availability.

Published: January 2019

Background: Prior to the de!nitive closure of wound by skin graft, it is essential for the recipient wound to be prepared adequately. Honey has been shown to exert a valuable effect in wound healing, atributale to its six favorable characteristics. This clinical study is proposed to determine the effectiveness of a specific sample honey (Madu Nusantara®) in accelarating the time of wound bed preparation in chronic traumatic wound.Methods: A randomized non-blinded clinical trial was done on patients with chronic traumatic wound who required wound bed preparation before definitive closure, during a one-year period. A total of 18 patients were included in the study, divided into two interventions. One has wound treated by topical application of honey (HDR), and controls were treated by conventional dressing (CDR). Daily wound treatment and evaluation was done using The Bates-Jensen Wound Assesment Tool until wound-bed was ready to be skin-grafted. The time required until wounds were ready to be grafted was also measured in both groups.Results: The mean time of wound bed preparation in HDR gorup was 12 days (n=11), and 26 days in CDR group(n=7, p 0.0055). The mean Bates-Jensen score of HDR improved from 45.45 before treatment to 23.36, versus 44.00 to 29.00 in CDR subjects.Conclusion: A favorable wound bed is essential prior to skin grafting.Our data shows that topical application of honey is more effective in accelerating the time of wound bed preparation than conventional dressing in patients with chronic traumatic wound.
Building strong health supply chain systems: the visibility and analytics network approach to improving the Nigeria immunisation supply chain
Authors: Ottih Chibuzo , Cussen Kevin , Mustafa Mahmud
Published: January 2019

Background

Health supply chain managers are unable to effectively monitor the performance of the immunisation supply chain in Nigeria. As a result, they are unable to make effective, data-driven decisions. This results in poor vaccine availability at some service delivery points. A lack of reliable data for evidence-based decision making is a significant contributor to this challenge.

Method

The visibility and analytics network (VAN) principles were introduced to enable end-to-end visibility in the immunisation supply chain and logistics (ISCL) system and make more accurate data available to health supply chain managers.

Results

The application of the VAN principles has led to improved data collection, real-time stock visibility and enhanced data analytics framework. This enhanced visibility has promoted a culture of accountability and data-driven decision-making, previously unattainable. Health supply chain managers are now equipped with better skills and tools to promote effective operation of the immunisation supply chain.

Conclusion

The introduction of VAN principles has been an effective approach to improving data visibility and creating incremental improvements in the ISCL in Nigeria.

Authors: Mamytova E.
Published: January 2019

The aim is a prospective analysis of the results of laboratory studies of conservative treatment of 63 patients with traumatic brain injury of moderate severity. Of these, 21 patients (study group), along with the treatment provided by medical standards prescribed drug cerebrolysin. In the control group (42 people), patients received only standard therapy. We evaluated the dynamics of indicators of T-cell immunity. Treatment added with cerebrolysin led to positive changes among the indicators of cellular immunity and partial correction arising after TBI T-cell immunodeficiency due to an increase of the percentage of CD3+ and CD4+ T-cell subpopulations.

High concentrations of interleukin-1b potentiate the development of exudative-necrotic component specific inflammation and destruction of the lung tissue.
Antibacterial Properties of White Cotton/Naturally Brown-Colored Cotton Blended Fabrics
Authors: Wang Jia , Ma Mingbo , Zhou Wenlong
Published: January 2019

Naturally brown-colored cotton (NBCC) fibers have been reported as having excellent antibacterial and antioxidant properties. Generally, NBCC fibers are used in blends with other fibers (e.g., white cotton fiber) to improve yarn qualities and also produce more color shades. The antibacterial properties of NBCC/white cotton blends were investigated as spunlace nonwoven fabrics in this study. Pure NBCC fiber showed antibacterial activity of 91.7% and 86.9% against Staphylococcus aureus and Escherichia coli, respectively. Antibacterial activities of the blends containing greater than 70% brown cotton were very similar to those of NBCC fiber. The effects of scouring, laundering, and sunlight exposure on the antibacterial activity of the NBCC/white cotton blends were reported.
Lead-silver anode behavior for zinc electrowinning in sulfuric acid solution
Authors: Zhang Wei , Haskouri Sanae , Houlachi Georges , Ghali Edward
Published: January 2019

In recent years, a renewed interest in studying the electrochemical corrosion behavior of lead anodes during zinc electrowinning is probably due to the particularly high sulfuric acid concentrations in zinc electrolyte where lead alloy anodes have high cell voltage and high corrosion rate of lead. The high corrosion rate of lead alloy resulted in Pb contamination on zinc deposit. In zinc electrometallurgy, the electrolyte from a zinc-rich ore contains a significant amount of Mn2+. Mn2+ in the zinc electrolyte results in forming an oxide film on lead anodes during electrolysis. Pb-0.7% Ag anode is generally used in the zinc industry. To improve the technical performance and decrease product cost, other anodes, such as Pb-Ca or Pb-Ag-Ca or Pb-Ag-Ti or Pb-Ag-Se alloys were tested. Till now, none of them has succeeded in the substitution of Pb-Ag anodes in the zinc electrowinning. As an alloying element, silver in small quantities is considered because of the benefits that generates on the anode during electrolysis. During zinc electrolysis, lead dissolution into the zinc electrolyte can be harmful to the quality of zinc deposit. However, the lead silver alloy anode can decrease the lead content in the zinc deposit by pre-treated methods such as blasting and preconditioning.
Simulation of cement raw material deposits using plurigaussian technique
Authors: Yünsel Tayfun Yusuf
Published: January 2019

Plurigaussian simulation is a powerful and very effective technique for modelling subsurface rock type domain distribution and in-situ mining reserve analysis. Modelling of subsurface to reveal the rock type distribution plays a key role for raw material extraction planning and plant operations such as extraction, transportation and comminution strategies. Because, the raw material distribution defines the plant operations and final product quality (cement modulus). This study addresses the application of plurigaussian simulation technique to reveal the subsurface rock type distribution of a cement raw material deposit in Turkey. The rock type domains include the limestone, clayey limestone, marl and sandstone which are the basic four rock type classes effecting the cement modulus in the field. The simulation process is carried out using these four rock type data on a determined grid system. A series of tests are made for the validation of the plurigaussian simulation. As a result, the rock type distributions are presented as both 2D-3D graphics and tabulated. The limestone is found as a dominant rock type in the deposit. The marl – a natural clinker - is another widespread raw material in the field and is found interbedded with limestone across the study field. The unwanted sandstone existence exhibited a sparse distribution in reserve body. The results indicated that, the deposit can provide the required raw material for the plant, showing the localised rock type distribution. A detailed raw material extraction planning and scheduling may be made using the results of this study.
Application of the nanoindentation technique for the characterization of varved clay
Authors: Tankiewicz Matylda
Published: January 2019

Nanoindentation is a test carried out in a small scale, during which a rigid indenter (of known hardness and geometry) is pressed into the tested material. The results of the test are the load and unload curves, from which the harerial characterized by high heterogeneity (like soil – composed of grains and particles of different size and mineral composition), the use of multiple nanoindentation on a predefined grid (Grid Indentation Technique) is reasonable. It allows for the determination of the morphology of the material in a selected scale of observation. In the study, nanoindetation tests were performed on samples of varved clay - soil composed of two alternately arranged layers - occurring near the city of Bełchatów in central Poland. Due to the layered structure of the material, the tests were carried out for both layers separately. The outcomes show that there are significant differences in the values of their mechanical properties. Application of the deconvolution technique also allowed for the estimation of the number of components of both layers and their mechanical properties.
Effect of hardening parameters of wood preservatives based on tannin copolymers
Authors: Sommerauer Lukas , Thevenon Marie-France , Petutschnigg Alexander , Tondi Gianluca
Published: January 2019

Amongst polyphenols, tannins belong to the most effective chemical protection systems against biological attack on trees. Tannins are water-soluble and are thus leached out easily when used for wood protection.In situpolymerized tannin-hexamine wood preservatives have better leaching resistance (LR), but they do not resist weathering. In this study, tannin copolymer formulations were prepared with hexamine, formaldehyde, furfural, glyoxal, furfuryl alcohol and maleic anhydride, impregnated in wood, and cured at higher temperatures. The wood samples treated with these formulations were tested for their anti-swelling efficiency (ASE), leaching behavior, mechanical properties, and their resistance against fire, weathering and biological attack. Several tannin-treated specimens showed improved hardness and enhanced leaching and fire resistance. Some formulations also responded well to artificial weathering cycles, but natural weathering cycles deteriorated their performance. Samples treated with maleic anhydride showed improved leachability and high biological resistances, even without the addition of inorganic biocides. These organic and bio-friendly products can be considered as promising alternatives to heavy metal-based wood preservatives.
Antonym adjective pairs and prosodic iconicity: evidence from letter replications in an English blogger corpus
Authors: Fuchs Susanne , Savin Egor , Solt Stephanie , Ebert Cornelia , Krifka Manfred
Published: January 2019

While the general assumption has long been that natural languages exhibit an arbitrary pairing of form and meaning, there is increasing empirical evidence that iconicity in language is not uncommon. One example from spoken language involves iconic prosodic modulation, i.e. the changing of prosodic features such as duration and fundamental frequency to express meanings such as size and speed. In this paper, we use data from an English social media corpus, with 140 million words written by 19,320 bloggers, to investigate a counterpart to iconic prosodic modulation in written language, namely letter replications (e.g.loooong). We examine pairs of gradable adjectives such asshort/long,tiny/hugeandfast/slow, finding a higher frequency of letter replications for adjectives associated with greater size or spatial/temporal extent. We did not find an iconic effect on the number of replicated letters. Our results show evidence for iconic prosody in written language, and further demonstrate that social media databases offer an excellent opportunity to investigate naturalistic written language.
On a conjecture about generalized Q-recurrence
Authors: Alkan Altug
Published: January 2019

Chaotic meta-Fibonacci sequences which are generated by intriguing examples of nonlinear recurrences still keep their mystery although substantial progress has been made in terms of well-behaved solutions of nested recurrences. In this study, a recent generalization of Hofstadter’s famous Q-sequence is studied beyond the known methods of generational approaches in order to propose a generalized conjecture regarding the existence of infinitely many different solutions for all corresponding recurrences of this generalization.
Poeticizing the economy: The Corsican language in a nexus of pride and profit
Authors: Jaffe Alexandra
Published: January 2019

This article explores the carefully managed semiotic complex found in the Corsican village of Pigna with respect to the themes of pride and profit in the valuation of minority languages. This complex includes the careful coordination of color, graphics, the use of the Corsican language, as well as high-tech soundscaping of place through QR codes that tie specific locales to Corsican music and multilingual texts. This display, labeled the “poeticizing of the economy” by a key social actor, is directed both at the many tourists who visit the village as well as Corsican visitors and locals. It is linked to an effort to embed Corsican linguistic and musical heritage in new practices that both create place and integrate tradition and modernity. On the one hand, these practices can be linked to discourses of both “pride” and “profit” (Duchêne and Heller 2012) attested in many minority language contexts. On the other hand, I argue that the Pigna esthetic indexes a shift in the framework for cultural and linguistic revitalization from one that emphasizes a return to past native speaker communicative practice to one that focuses on the collective agency and identity associated with style and stylization and “transactional,” or situated authenticities.

Authors: Bas Erdal , Ozarslan Ramazan , Baleanu Dumitru
Published: January 2019

In this work, we bring a different approach for Sturm-Liouville problems having Bessel and hydrogen atom type and we provide a basis for direct and inverse problems. From this point of view, we find representations of solutions and asymptotic expansions for eigenfunctions. Furthermore, some numerical estimations are given to illustrate the necessity of the Sturm-Liouville difference equations with the potential function for the convenience to the spectral theory. The behavior of eigenfunctions for the Sturm-Liouville problem having Bessel and hydrogen atom potential type is analyzed and compared to each other. And then, comparisons are showed by tables and figures.

These models have valuable applications in mathematical physics. The results of the constructed model, along with some graphical representations provide the basic knowlegde about these models. The derived results have various applications in applied science.
Thermo-convective instability in a rotating ferromagnetic fluid layer with temperature modulation
Authors: Sibanda Precious , Adam Ibrahim Noreldin Osman
Published: January 2019

We study the thermoconvective instability in a rotating ferromagnetic fluid confined between two parallel infinite plates with temperature modulation at the boundaries. We use weakly nonlinear stability theory to analyze the stationary convection in terms of critical Rayleigh numbers. The influence of parameters such as the Taylor number, the ratio of the magnetic force to the buoyancy force and the magnetization on the flow behaviour and structure are investigated. The heat transfer coefficient is analyzed for both the in-phase and the out-of-phase modulations. A truncated Fourier series is used to obtain a set of ordinary differential equations for the time evolution of the amplitude of convection for the ferromagnetic fluid flow. The system of differential equations is solved using a recent multi-domain spectral collocation method that has not been fully tested on such systems before. The solutions sets are presented as sets of trajectories in the phase plane. For some supercritical values of the Rayleigh number, spiralling trajectories that transition to chaotic solutions are obtained. Additional results are presented in terms of streamlines and isotherms for various Rayleigh numbers.
No evidence for airborne transmission of Toxoplasma gondii in a very high prevalence area in Lancaster County
Authors: Wadhawan Abhishek , Hill Dolores E. , Dagdag Aline , Mohyuddin Hira , Donnelly Patrick , Jones Jeffrey L. , Postolache Teodor T.
Published: January 2019

Background: Toxoplasma gondii (T. gondii) has been associated with acute food-borne illness, chronic low-grade inflammation, neuropsychiatric conditions and reactivation of chronic latent infection in immunocompetent hosts. Primary infection with T. gondii in pregnant women can lead to congenital toxoplasmosis. In addition to well-known oral tissue-cyst or oocyst ingestion, we hypothesized that the very high prevalence of T. gondii in certain populations exposed to agricultural dust could be, in part, a consequence of airborne infection with oocysts. Methods: We collected environmental dust samples from an area with a reportedly high T. gondii seroprevalence in the Old Order Amish population, in Lancaster, Pennsylvania. Samples included: a) air filters from air-conditioning units; b) swabs of settled dust; and c) vacuum filters containing airborne field dust. Pools of the swabs and shredded sub-samples of the air filters were fed to pigs, with inoculation into mice of heart tissue from seroconverted pigs. We also investigated the presence of T. gondii DNA using PCR amplification. Results: Only one pig seroconverted. However, bioassay of pig heart tissue further inoculated into mice showed no evidence of T. gondii infection. Consistently, no evidence of T. gondii DNA was revealed in any sample. Conclusions: No evidence of airborne transmission was found in the environmental samples that were examined.
Spirituelle und sakrale Räume
Authors: Kopp Stefan
Published: January 2019

Als spirituelle und sakrale Räume können mit einem anthropologisch erweiterten Raumbegriff neben den neueren Räumen der Stille und Andachtsräumen bzw. den klassischen Kirchen- und Kapellenräumen auch „heilige Räume“ der Spiritualität und der Liturgie bezeichnet werden. Im Kontext von Spiritual Care können sie der Spiritualität kranker Menschen und derer, die sie pflegen, Raum geben sowie als sinnstiftend und heilsam erfahren werden. Dabei geht es um die Frage, was Menschen hilft, eine Offenheit für Transzendenz zu finden und die liebende Zuwendung Gottes zu erfahren.

Unterstützung von Spiritual Care durch räumliche Gestaltung von Gesundheitsbauten
Authors: Brichetti Katharina
Published: January 2019

Die räumliche Gestaltung von Gesundheitsbauten kann spirituelle Bedürfnisse und Spiritual Care behindern oder begünstigen. Patienten, Besucher und Personal erleben beispielsweise den Charakter eines Krankenzimmers als oft durchaus eindringliche Anmutungen und Stimmungen, sogenannte Atmosphären. Solches Erleben ist leiblich-räumlich. Ebenso ist es vieldimensional synästhetisch, integriert alle Sinne sowie Sinne und Geist.

Der Ausdruck „Synästhesie“ wird hier bewusst liberal in einer informellen und tendenziell weiten Bedeutung verstanden. Diese entspricht einer in vielen Kontexten etablierten und nach meinem Dafürhalten sachdienlichen Verwendung, auch wenn die originale sinnesphysiologische Definition dabei gelockert, erweitert und teilweise umgedeutet erscheint.

Der ganze Mensch ist davon betroffen und berührt, wie die Umgebung gestaltet ist, als Patient oft auf besonders intensive Weise. Doch wie lassen sich Räume so gestalten, dass ihre Grundstimmung spirituelle Bedürfnisse und Spiritual Care unterstützt? Inspiration läßt sich aus Erkenntnissen zum Welt-Erleben von Patienten, aus Ansätzen der „Healing Architecture“ und aus der Gestaltung sakraler Bauten und Räume gewinnen.
Spirituelle Räume
Authors: Wüthrich Matthias D.
Published: January 2019

Schwerstkranke, sterbende Menschen verbringen die letzte Phase ihres Lebens oft nicht in ihren vertrauten Wohnräumen, sondern müssen in fremde Räume wechseln. Welchen Einfluss kann Spiritual Care auf das „Raum-Erleben“ bzw. die räumliche Erfahrung dieser Menschen ausüben? Der vorliegende Artikel gibt auf diese Frage keine unmittelbare Antwort. Er leistet aber insofern einen Beitrag zu ihrer Beantwortung, als er raumtheoretisch darüber nachdenkt, wie das „Raum-Erleben“ von schwerstkranken, sterbenden Menschen im Kontext von Spiritual Care angemessen beschrieben und erfahrungsnah erfasst werden kann. Dazu wird das raumtheoretische Konzept eines interpersonalen Raumes entwickelt, der schließlich auch in seiner spirituellen Dimension dargelegt wird.
Analysis for Various Effects of Relaxation Time and Wall Properties on Compressible Maxwellian Peristaltic Slip Flow
Authors: Eldesoky Islam M. , Abumandour Ramzy M. , Abdelwahab Essam T.
Published: January 2019

The present study is related to indicating the several effects of the relaxation time, dynamic behaviour of wall properties and slip conditions at the boundaries on the peristaltic locomotion of viscous non-Newtonian Maxwell fluid flow through a two-dimensional (2D) horizontal flexible sinusoidal wave-shaped channel. An approximated theoretical model is constructed. The solution of the governing equations is developed using the perturbation method. Small amplitude ratio “ratio between amplitude of the wave and half channel width” for the wavy transport is considered for describing the velocity and pressure distributions. Different factors of wall features such as damping force coefficient, wall tension parameter, wall bending coefficient and spring stiffness factor in addition to various flow parameters such as the compressibility factor, Reynolds number, slip coefficient and also the main parameter of interest relaxation time are involved in the mathematical calculations and discussed through graphical representation. Graphs for mean axial velocity, perturbation function and velocity at the wall distributions using the previous coefficients are plotted and then discussed in detail. Results indicate that wall properties, compressibility factor and relaxation time in the presence of peristaltic transport have a significant effect on velocity distributions. The damping factor, wall tension, slip parameter and relaxation time are reducing the mean axial velocity and raising the reversal flow but, the wall elasticity factor enhances the mean axial velocity. Also, the liquid compressibility has a strong effect on the dynamics of the flow.
Melt Elongation Flow Behavior of Low-Density Polyethylene Composites Filled with Nanoscale Zinc Oxide
Authors: Liang Ji Zhao
Published: January 2019

The melt elongation flow properties of low-density polyethylene/nanoscale zinc oxide (nano-ZnO) composites were studied using a Rheotens rheometer (Göttfert Werkstoff-Prüfmaschinen GmbH, Buchen, Germany). The die extrusion rate varied from 9 to 36 mm/s, the temperature ranged from 160°C to 200°C, and the nano-ZnO weight fraction range was from 0.2 to 4 weight percent (wt.%). The results showed that the melt elongation stress increased with the increasing elongation strain rate; the melt elongation viscosity decreased with the increasing temperature, and the temperature dependence obeyed the Arrhenius equation. The melt elongation viscosity of the composites with 0.4–0.8 wt.% nano-ZnO was lower in the whole composite system. Moreover, the melt elongation viscosity increased when the elongation strain rate was lower than 0.3 s−1 and then decreased with the increasing elongation strain rate; the melt elongation viscosity reached a maximum at an elongation strain rate around 0.3 s−1 and presented the stress hardening phenomenon.

Published: January 2019

Objectives: Sexual life may change during pregnancy. Due to negative attitudes toward having sex, unpleasant feeling, and fear of several issues, women might avoid vaginal intercourse during pregnancy. Therefore, the present systematic review aimed to investigate the frequency of vaginal intercourse in pregnancy. Materials and Methods: Comprehensive literature review was conducted to find the relevant articles published (from December 1990 to April 2018) on the issue including observational studies (e.g., cross-sectional and cohort studies) that certainly determined the mean frequency of vaginal sex throughout pregnancy. In this regard, online international databases such as ISI, PubMed, Scopus, Cochrane, and Google Scholar were independently explored and checked by two authors. Duplicate articles were removed by the EndNote X7 Reference Manager. The results were analyzed using RevMan 5.3 software. The P < 0.05 was considered significant. Results: Totally, after excluding the duplicate and irrelevant articles based on having the mean frequency of vaginal intercourse during pregnancy, 13 articles were obtained. The range of vaginal intercourse frequency varied from 6.01 to 21 times every month pre-pregnancy, 3.67-9.87 times monthly in the first trimester, 2.78-7.21 times monthly in the second trimester, and 1.35-5.9 times monthly in the third trimester. Five out of the 13 selected articles reporting the mean and standard deviation were entered the current meta-analysis. The frequency of vaginal intercourse was obtained 7.75 (7.13-8.38) times monthly prior to pregnancy, 4.16 (3.86-4.46) times in the first trimester, 6.37 (5.60-7.14) times monthly in the second trimester, and 1.81 (1.49-2.13) times monthly in the third trimester. Conclusions: Generally, the frequency of vaginal intercourse decreased in the first trimester while increasing in the second trimester. However, a sharp decline was observed between the second and third trimesters of pregnancy.

Objectives: This study aimed to observe the difference in the area of endometriosis lesions and the histopathology of inflammatory cells and granuloma masses in an endometriosis mouse model treated with endometrial cell implants, endometrioma capsules, and adenomyosis tissue. Materials and Methods: This is an experimental study with posttest-only research design which was conducted with the control group. Thirty-two mice (Mus musculus) were injected with 0.2 mL/mice cyclosporin A and then were divided into three groups which were injected with endometrial tissue from the uterine cavity (group A), endometriosis from endometrioma capsule (group B), and endometriosis from adenomyosis (group C). The injection was done slowly into the peritoneal cavity, 0.1 mL each, and followed by intramuscularly Ethinyl estradiol, 0.2 μG/mice. On the 15th days, mice were dissected to observe the peritoneal endometriosis implant and microscopic examination with hematoxylin-eosin (HE) staining to determine the inflammatory cell infiltration and mass granuloma presence. Data were analyzed using SPSS, version 19. Results: The study obtained that the area of implanted endometriosis lesions in group C covered a larger area of endometriosis implants than other groups (P < 0.05). The peritoneal damage in group C was the most severe based on the Klopfleisch method (P < 0.05), with mass granuloma and massive infiltration of inflammatory cells and fibrous connective tissue formation occurring in muscle tissue. Conclusions: The implantation of adenomyosis cell tissue is the best method to develop mice model of endometriosis based on its inflammatory infiltration, the extent of lesion implant, and granuloma mass

Published: January 2019

Objectives: Polycystic ovary syndrome (PCOS) is considered as one of the causes of infertility. Anti-Mullerian hormone (AMH) is 2-3 times higher in patients with the PCOS compared to others. The present study aimed to survey the association between basal AMH levels and ovarian response in infertile PCOS patients. Materials and Methods: In this cross-sectional study, 70 infertile PCOS women were enrolled referring to Milad Infertility Center (Mashhad, Iran) from May 2011 to April 2012. The basal blood level of AMH was evaluated. The patients received 5 mg of letrozole from the fifth cycle day (for 5 days) and then received 150 units of gonal F in the form of the recombinant follicle-stimulating hormone (FSH) on the ninth day of the cycle. Five thousand units of human chorionic gonadotropin (hCG) were prescribed for the patients who had one follicle of ≥ 18mm. Then, they should have had intercourse 36 hours later. After ovulation induction (OI) on the 10th cycle day, the second serum sample of AMH was taken. Results: Changes of AMH did not have a significant relationship with the ovarian response, namely, it was lower in patients with positive ovarian response compared to those without any ovarian response. In addition, the basal level of AMH in patients with a positive response (3.91 ± 2.14) had no significant difference with the secondary AMH (3.27 ± 2.39) after the OI (P = 0.19). Conclusions: Generally, the AMH was not a predictor of ovarian response in PCOS patients and the amount of AMH reduced after the treatment. This effect was maybe related to letrozole and gonadotropin.

Objectives: This study aimed to measure the umbilical cord indices (UCIs) after birth and to determine its relationship with prenatal complications. Materials and Methods: The present analytical cross-sectional study was conducted on all the pregnant women admitted to AlZahra hospital of Rasht. After birth, the umbilical cord was measured in terms of the appearance, number of vascular coils, and umbilical cord length. In addition, the umbilical cord vascular coils index was calculated. Further, maternal and neonatal variables were evaluated. Results: The mean number of umbilical cord coils, umbilical cord length, and the umbilical cord coiling index for 397 umbilical cords were obtained as 16.02 ± 4.48, 51.6 ± 12.0 and 0.31 ± 0.05 cm, respectively. In evaluating the state of the coil, 9.8% were found as hypocoil while the remaining were either hypercoil (10.3%) or normocoil (79.85%). Furthermore, a significant difference was observed between the umbilical cord coiling index, as well as gestational hypertension and abnormal fetal heart rate (HR) (P < 0.05). In the final logistic regression model, the umbilical cord length was recognized as a predictor variable for neonatal complications. Moreover, in multiple analyses regarding the effects of umbilical cord coiling index on neonatal complications by controlling the interferences, variables such as maternal age and parity in addition to the coil length were considered as predictors of neonatal complications. Conclusions: Generally, the abnormal umbilical cord coiling index was associated with pregnancy blood pressure (BP) and abnormal fetus HR. Therefore, diagnosing antenatal umbilical cord coiling index can be helpful in recognition of embryos at risk through a faster treatment process.

Objectives: The antioxidative role of Galega officinalis extract has been reported in several studies. However, this experimental study was designed in order to investigate the impacts of G. officinalis extract against parameters, such as histological, hormonal, and oxidative stress parameters, which were induced by ovarian torsion/detorsion. Materials and Methods: Adult female Wistar rats (n = 28) were randomly divided into 4 groups including sham (G1), ovarian torsion for 3 hours then-after detorsion (G2 or TD), ovarian torsion-detorsion orally received 50 mg/kg extract of G. officinalis (G3 or TDGO), healthy rats orally received 50 mg/kg hydroalcoholic extract of G. officinalis (G4 or GO). Ten days after torsion-detorsion, rats were sacrificed and their ovaries, and their blood levels of hormones including estrogen and testosterone, as well as some oxidative stress markers were assayed. Results: The structure of ovaries in TD groups of the study showed a notable change compared to other groups. The serum levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH), and also estrogen significantly decreased in TD group, while treatment with G. officinalis could prevent from decreasing mentioned parameters. Furthermore, although torsion-detorsion led to increasing the serum level of malondialdehyde (MDA), it was decreased after administration of G. officinalis. Conclusions: Obtained results showed that G. officinalis could be useful in elevating the estrogen level, reducing the oxidative stress marker (i.e. MDA) and ovarian tissue damages induced by torsion-detorsion.

Objectives: The use of herbs which has been increasing worldwide, requires special considerations particularly in pregnant woman. The present study was conducted at Alzahra Teaching hospital (from March 2016 to August 2017) to explore the pattern of herbal use during pregnancy in Guilan province (North of Iran). Materials and Methods: Data were obtained from 836 eligible women, who were interviewed at postnatal ward, and were analyzed. Results: The results of the study showed that 19.6% of the women consumed herbs during pregnancy. The most commonly used herbs included mint, flixweld, and cinnamon; in addition, the most prevalent indications resulted from these herbs consumption were gastrointestinal complications and cold. The rate of herbal consumption in pregnancy was related to education (P=0.001) and resistance (P=0.008); however, no relation was found regarding age (P=0.203), employment (P=0.255), or gravity (P=0.935). Conclusions: Although the findings of this study were preferable to those of some other studies, due to the importance of the issue, it is vital that health care providers to be open to question the herbal use during pregnancy.
Recepción del Qurʾān en la Comunidad LGBTQ Musulmana
Authors: al-Haqq Kugle Scott Siraj
Published: January 2019

El asesinato homofóbico masivo en la discoteca Pulse en Orlando, Florida en el año 2016 demuestra lo urgente que es para los musulmanes y sus aliados una reexaminación crítica de su concepción de los musulmanes queer (es decir, personas musulmanas lesbianas, gais, bisexuales y transgénero). Los musulmanes no pueden fingir que el Islam no tiene nada que ver con la matanza, ya que el asesino habría sido motivado por su comprensión del Islam. Sin embargo, mi investigación demuestra que el Islam no condena inherentemente a las personas LGBT. Aunque haya sido interpretado de ese modo, sus fuentes escritas están abiertas a otras interpretaciones. Este artículo muestra las distintas maneras en las cuales los musulmanes queer reciben el Qurʾān. En entrevistas con miembros de esta comunidad (provenientes de distintos grupos étnicos, nacionales y doctrinarios) sobresale la siguiente reflexión: una religión que no se enfoca en las experiencias vitales de las personas, especialmente de aquellas quienes luchan en contra de la marginalización y la injusticia, no es una religión compasiva. Los musulmanes queer consideran ciertos principios esenciales para interpretar el Qurʾān, tales como una evaluación realista de la vida social, la afirmación de la diversidad profunda de la creación, la protección de la dignidad humana, la fidelidad a la justicia y la insistencia en el cuidado y la compasión como fundamentos del Islam.
Jardines del alma. Hacia una teología comparada de la Alhambra y el Castillo interior
Authors: Carrión María
Published: January 2019

Esta lectura comparada de los conjuntos monumentales de la Alhambra en Granada y el Castillo interior de Teresa de Jesús es una rêverie teológica y literaria que propone entender estos dos textos como jardines del alma, es decir, como espacios donde florece un sentido espiritual y un pensamiento religioso que trasciende toda una serie de fronteras. Estos dos textos son tan distintos que se podría decir que no se prestan a una lectura comparada, mucho menos una con un centro referencial teológico. En suma, se puede entender que esta empresa no sea aconsejable, y que estos dos textos se deban dejar separados motu proprio, como si fueran agua y aceite. Sin subestimar estas diferencias, y sin ánimo de menoscabar las tradiciones religiosas y literarias que los han canonizado por separado, este ensayo contempla la posibilidad de una teología comparada con estos dos textos, la cual plantea una clara relación con lo divino y que entiende lo sublime en la diferencia de estos espacios. Con esta lectura se podrá apreciar un amor sin fronteras por la naturaleza y, sobre todo, por el agua y sus propiedades divinas de abundancia y prodigalidad, que se pueden leer como medio y canal de fe y esperanza. Este es amor protegido por un amplio paisaje de flores, frutas, árboles y demás flora natural y artística dentro y fuera de los palacios nazaríes de la Alhambra y del tratado místico de Teresa de Jesús. Este amor por las maravillas de los jardines, por la belleza más grande, por la bendición del agua, y por Dios-Allāh mueve la teología comparada que motiva a escribir estas páginas.

El algodón es la fibra natural de mayor importancia en el sector textil y representa unos de los productos básicos en la economía de más de 100 países, con un aproximado de 150 países que exportan o importan esta materia prima [7]. Su cultivo se considera como uno de los   más intensivos, puesto que requiere grandes cantidades de agua, pesticidas y fertilizantes, lo que implica que los impactos ambientales sean mayores (Daño a la Salud Humana, Daño a los Ecosistemas y Daño a la disponibilidad de recursos); también se contempla los impactos que se generan en el proceso de la producción de la tela de algodón. Para la minimización de impactos generados en la cadena productiva se hace uso de la aplicación del análisis del ciclo de vida consecuencial al proceso de cuna a puerta, usando el software Umberto NTX LCA y la metodología ReCiPe a partir de información secundaria. Disponibilidad de recursos fue la categoría que mostraba mayores impactos en el proceso (212,14 puntos) y calidad de ecosistema, 127,84 puntos como categoría de menor impacto. Con las mejoras realizadas al proceso se tiene una reducción de 53,01 puntos.
