Writing Disability | Disabling Writing: E.T. Russian and the Fragmentation of Texts and Textures
Authors: Tarapata Olga
Published: March 2019

This paper focuses on the US-American queer disability artist E.T. Russian and the question of how the experience of disability can be translated into artistic experience and practice. Russian’s The Ring of Fire Anthology (2014) draws attention to the insufficiency of words and language and deploys a form of literary collage that presents an empowering testimony to her life as an amputee. While the author’s account of the pitfalls entailed in prosthetics as well as gender and class struggles is captivating in itself, the force of her work resides elsewhere: the reader cannot escape the ecstasy of fragmentation and intertextuality provoked by the arrangement, or derangement, of image and text. It is Russian’s palimpsest of essays, comics, interviews, dictionary entries, erotica, lonely hearts ads, poems, and technical drawings that offers an entryway into the multiplicity and fluidity of disability experience.
Deafness and Ethnic Identity: The Idea of a Deaf State and its Resonances with American Exceptionalism and Frontier Ideology
Authors: Rana Marion
Published: March 2019

This article focuses on the nineteenth century as a pivotal time for the development of a Deaf identity in the United States and examines the way John Jacob Flournoy’s idea of a “Deaf-Mute Commonwealth” touches upon core themes of American culture studies and history. In employing pivotal democratic ideas such as egalitarianism, liberty, and self-representation as well as elements of manifest destiny such as exceptionalism and the frontier ideology in order to raise support for a Deaf State, the creation and perpetuation of a Deaf identity bears strong similarities to the processes of American nation-building. This article will show how the endeavor to found a Deaf state was indicative of the separationist and secessionist movements in the United States at that time, and remains relevant to Deaf group identity today.
Whose Spirit is Eager? The Referent of Πνεῦμα in Mark 14,38 and the Intended Comparison
Authors: Bennema Cornelis
Published: March 2019

Scholarship is divided on the referent of πνεῦμα in Mark 14,38. Most scholars (mainly English and French) favour an anthropological referent while a minority (some English and most German scholars) supports a divine referent. This study proposes that 14,38 refers to the divine spirit and that, in the broader context of Mark 13, the intended comparison is not of an inner human struggle but the contrast between two kinds of human existence. Members of the Jesus group can rely on divine assistance in testing situations while non-members have no access to this divine resource.
Laboratory Characterization of Asphalt Binders Containing a Chemical-Based Warm Mix Asphalt Additive
Authors: Rani Shivani , Ghabchi Rouzbeh , Ali Syed Ashik , Zaman Musharraf
Published: March 2019

Different technologies, namely foamed asphalt, synthetic waxes, zeolites, and chemical additives, are used to produce warm mix asphalt (WMA). This study was undertaken to evaluate the effect of using different amounts of an amine-based chemical WMA additive on the rheology, performance grade (PG), and moisture-induced damage potential of an asphalt binder (PG 58-28). Superpave specifications were used to evaluate the rheological properties and PG of the asphalt binder. Also, a mechanistic approach-based on the surface free energy (SFE) method was used to evaluate the moisture-induced damage potential of the asphalt binder combined with commonly used aggregates in an asphalt mix. It was found that the dynamic viscosity of the asphalt binder was not significantly affected after blending it with the WMA additive. It was also observed that the Superpave high-temperature PG and the rutting factor did not reduce by an increase in the WMA additive content. However, the continuous low-temperature PG of the asphalt binder decreased with an increase in the amount of WMA additive. Furthermore, it was found that the fatigue resistance increased after blending the binder with the WMA additive. The SFE results of the asphalt binder revealed that the WMA additive used in this study reduced the moisture-induced damage potential of the asphalt mixes. However, the extent of this improvement was found to largely depend on the aggregate type. The outcomes of this study are expected to help better understand the influence of amine-based chemical WMA additives on rheological and long-term performance of asphalt mix.

Visual History: The Past in Pictures
Authors: Bleichmar Daniela , Schwartz Vanessa R.
Published: March 2019

This essay defines the category of “visual history” and introduces its operations across the essays included in this special issue. It proposes that such narratives accelerated time in cultures where it became increasingly common to traverse spatial distances. In this way, visual histories are not simply guides to the times, but guides to time itself.
The Medium Is the Messagerie
Authors: Doyle Allan
Published: March 2019

This paper analyzes the contributions of Théodore Géricault to the second volume of Baron Isidore Taylor, Charles Nodier, and Alphonse de Cailleux’s Voyages pittoresques: Normandie (1820; 1825) within the context of French Restoration historiography. It argues that Géricault’s prints are allegorical commentaries on the production of visual history during this period as much as they are examples of it.
Eyewitnessed Historia and the Renaissance Media Revolution: Visual Histories of the Council of Trent
Authors: Levy Evonne
Published: March 2019

This essay examines the collision of Renaissance narrative or historia in the visual arts and the eyewitnessed event and the pressure put on that convergence by the dissemination of the latter in the new print media. The example discussed here is the Council of Trent, a storyless but signal event that conformed with difficulty to an ideal “historia,” and one that was often depicted after eyewitnessed scenes of the event had already been disseminated in engravings. The veracity of the scene captured in a print created new chains of media: prints led to paintings, and to more prints, and images led to written history, rather than vice versa.

Published: March 2019

El objetivo de este estudio fue comprender los modelos de Educación para la Salud en programas de Salud Sexual y Reproductiva (SSR) para jóvenes en Medellín 2004-2010. Se desarrolló a través de metodología cualitativa con teoría fundamentada, realizando entrevistas en profundidad a 8 jóvenes y 12 operadores técnicos (16 entrevistas en la primera fase y 4 en la segunda), las cuales fueron codificadas para extraer las categorías de las cuales emergen los resultados. Se estableció que en los modelos de educación presentes en los programas no se tuvieron en cuenta las necesidades de los jóvenes para su formación en SSR. Existe un amplio desarrollo en políticas públicas de juventud, pero los programas de SSR dirigidos a jóvenes siguen teniendo como único sustento las políticas públicas de salud, por esto se deben tener en cuenta las necesidades de los jóvenes para garantizar más éxito en la ejecución.
Muy bonito todo. Investigar imágenes y objetos contemporáneos desde la cultura mediática y la cultura popular
Authors: Salazar Edward
Published: March 2019

El diseño es objeto de investigación para las ciencias sociales, al tiempo que los métodos de esta se alimentan de la producción del diseño. Esta relación objetos-sujetos de estudio se ha intensificado con el desarrollo de ambas disciplinas, aunque la relación no ha sido igualmente evidente para ambos campos. Las ciencias sociales y las humanidades la han explorado más desde los estudios visuales y de la cultura material, mientras que solo en algunos casos el diseño ha apelado a las ciencias soåciales para las indagaciones previas a la creación de una pieza. Para ver las maneras en las que el diseño y la investigación se cruzan, este artículo aborda tanto la creación como el análisis de la cultura material y visual, utilizando como casos de estudio procesos investigativos sobre la moda, lo masivo y la cultura popular. Concluye con una reflexión sobre los aprendizajes teóricos y conceptuales que se pueden sacar desde la investigación, apuntando al concepto de lo bonito como una manera de trabajar metodológicamente.
OCT-guided Percutaneous Coronary Intervention in Bifurcation Lesions
Authors: Longobardo Luca , Mattesini Alessio , Valente Serafina , Di Mario Carlo ,   Department of Clinical and Experimental Medicine, University of Messina, Messina, Italy
Published: March 2019

Coronary artery bifurcation lesions remain challenging despite significant advancements in stent technology and development of specific bifurcation stenting approaches. Optical coherence tomography (OCT) is the intracoronary imaging technique with the highest resolution and can generate automatically contoured lumen areas across the variable geometry of bifurcation lesions. Knowledge of plaque severity and composition facilitates planning of the best strategy for percutaneous coronary intervention (PCI) and stenting. In particular, the provisional stent strategy preferred in this context can be modified when there is high risk of side-branch compromise at the ostium after main vessel stenting. OCT is unique because it allows the identification of the site of guide wire crossing, an important determinant of the final result. OCT can also be used to assess the procedural success of new dedicated bifurcation stent technologies and for the evaluation at follow-up of potential predictors of stent thrombosis, including stent malapposition, stent under-expansion and stent-edge dissection. Finally, the development of 3D OCT allows a better evaluation of coronary anatomy – particularly of side branch ostium that is difficult to visualise by 2D OCT – further improving the value of this technique in guiding PCI in these patients.

Large-bore Vascular Closure: New Devices and Techniques
Authors: van Wiechen Maarten P , Ligthart Jurgen M , Van Mieghem Nicolas M
Published: March 2019

Endovascular aneurysm repair, transcatheter aortic valve implantation and percutaneous mechanical circulatory support systems have become valuable alternatives to conventional surgery and even preferred strategies for a wide array of clinical entities. Their adoption in everyday practice is growing. These procedures require large-bore access into the femoral artery. Their use is thus associated with clinically significant vascular bleeding complications. Meticulous access site management is crucial for safe implementation of large-bore technologies and includes accurate puncture technique and reliable percutaneous closure devices. This article reviews different strategies for obtaining femoral access and contemporary percutaneous closure technologies.
Espacios urbanos para el desarrollo de los oficios en la América hispana: el caso de la Audiencia de Quito
Authors: Paniagua Pérez Jesús
Published: March 2019

Este artículo tiene el objetivo estudiar los espacios de localización del ejercicio de los oficios mecánicos en cuatro ciudades de la Audiencia de Quito —Quito, Cuenca, Guayaquil y Riobamba— durante el período de dominación española, entendiéndolas como una manifestación del espacio social. Para ello se han consultado diferentes archivos en Ecuador y España, así como una abundante bibliografía, especialmente la producida en Ecuador. Adicionalmente, se revisaron y construyeron mapas y planos, como documentos gráficos que complementaron la investigación. La lectura de las diversas fuentes llevó a unas conclusiones que indican que a pesar de los intentos gubernamentales por reubicar los oficios en un determinado espectro del espacio social, no se obtuvieron los resultados esperados y, por el contrario, se produjo una tendencia a la desconcentración de los mismos. Sin embargo, también se concluyó que con cierta frecuencia hubo condiciones no relacionadas con las disposiciones de las autoridades que obligaron a una cierta concentración de los grupos de artesanos, como la existencia de agua y diferentes materiales, la conservación del medio o las necesidades de la clientela.
Nanban Art and its Globality: A Case Study of the New Spanish Mural The Great Martyrdom of Japan in 1597
Authors: Arimura Rie
Published: March 2019

Traditionally, nanban art has been seen as a simple product of exchanges between Japan, Portugal and Spain. The historiography tends to solely focus on artistic contributions of the Society of Jesus due to the foundation of a painting school in Japan. Thereby, the relevance of the Indo-Portuguese route in the cross-cultural history has been emphasized. However, the research advances of the last decades identify that nanban works consist of artistic inheritances from diverse regions of the world which were connected through the Portuguese and Spanish transoceanic routes. Similarly, Japanese nanban art influenced the artistic productions on the other side of the world. In summary, nanban art cannot be understood without taking into account its global implications. This paper clarifies the changes in epistemological understanding of nanban art, and its redefinitions through a historiographical review. This work also shows the important role of Spanish America in the artistic exchange mechanisms; these interactions occurred reciprocally. Therefore, the New World was one of the regions where Japanese art significantly influenced local productions. To exemplify this phenomenon, we address the influence of nanban art on the mural painting The great martyrdom of Japan in 1597 in Cuernavaca, Morelos, Mexico.
Adatok Hekler Antal pályakezdéséhez levelek Hampel Józsefhez, legifj. Szász Károlyhoz és Koronghi Lippich Elekhez (1904–1909)
Authors: Mikó Árpád
Published: March 2019

Antal Hekler (1882-1940) was one of the central figures of Hungarian classical archaeology and art historiography in the first half of the 20th century. He began his career at the Hungarian National Museum and continued at the Museum of Fine Arts (where he laid the foundation for the Antique Collection), he organized the short-lived Hungarian Scientific Institute in Constantinople (1916-1918) and from 1918 until his death he headed the Art History Department at the Pázmány Péter University. The work of his pupils determined 20th century Hungarian art historiography.

The presented letters shed light on the start of Hekler’s career. After graduation in law, he changed professions. Upon his personal encounter with the art of classical antiquity he began studying classical archaeology; he was encouraged to do so by his family and friends, too. He enrolled at the university of Munich where he became one of Adolf Furtwängler’s favourite students. He obtained his doctoral degree under his supervision in 1907. During his studies he pursued correspondence with his patron in Budapest, József Hampel (curator of the Old Collection in the National Museum), informing him of the academic life in Munich, his researches, travels, forming scholarly contacts all over Europe. In Munich, then Paris, London, Italy he met the leading researchers, curators of leading museums. He did not only publish his research finding in German at that time, but the Archaeologiai Értesítő in Budapest edited by Hampel also carried writings by him. Back home Hampel took him on in the National Museum. (He participated in the excavations in Dunapentele [the ancient Intercisa] where he also wrote letters.) In addition to letters addressed to Hampel, some others written in Munich add information about the beginnings of Hekler’s career.

Clinical Activity of Nivolumab for Human Papilloma Virus-Related Juvenile-Onset Recurrent Respiratory Papillomatosis
Authors: Creelan Ben C. , Ahmad M. Usman , Kaszuba Frank J. , Khalil Farah K. , Welsh Allison W. , Ozdemirli Metin , Grant Nazaneen N. , Subramaniam Deepa S.
Published: March 2019

Background

Juvenile-onset recurrent respiratory papillomatosis (JO-RRP) is a human papilloma virus-mediated progressive benign neoplasm that affects children and young adults. Primary management consists of regular surgical debulking to maintain airway patency and vocal function. Like condyloma acuminata, JO-RRP is associated with immune dysregulation, and T cells isolated from papillomas express an anergic phenotype. Therefore, we hypothesized that programmed death protein 1 axis inhibition could stabilize tumor growth.

Materials and Methods

We treated two patients with refractory JO-RRP using nivolumab, with the primary objective of assessing clinical activity. We explored baseline papilloma features using immunohistochemistry and comprehensive genomic profiling.

Results

Both patients experienced symptomatic improvement, and interval laryngoscopies revealed a reduction in papillomatosis burden. One patient has not required subsequent surgical debridement for almost 2 years. On pathologic examination of pretreatment papillomas from both cases, infiltrating T cells were evident in the papilloma stroma, and papilloma programmed death ligand 1 expression was absent. Papilloma mutational load ranged between three and six mutations per megabase for each case. From on-treatment biopsy tissue, a higher amount of intraepithelial T cells and programmed death ligand 1 expression were detected in the papilloma.

Conclusion

Nivolumab appears to have promising activity in JO-RRP, and further clinical investigation with more patients in clinical trials is warranted.
Increased Mortality with Repeat Lumpectomy Alone After Ipsilateral Breast Tumor Recurrence
Authors: Su Yonghui , Guo Rong , Xue Jingyan , Chi Yayun , Chi Weiru , Wang Jia , Yang Benglong , Wu Jiong
Published: March 2019

Background

The benefit of repeat lumpectomy for ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery is currently inconclusive.

Materials and Methods

Patients with IBTR with definitive surgery were identified in the Surveillance, Epidemiology, and End Results registry between 1973 and 2013. The effect of different IBTR surgeries on overall and cancer-specific mortality was assessed using risk-adjusted Cox proportional hazard regression modeling and stratified propensity score-matching analysis (PSMA).

Results

Of the 5,098 patients with IBTR, 4,048 (79.4%) women underwent mastectomy and 1,050 (20.1%) underwent repeat lumpectomy. In multivariable Cox regression analysis, repeat lumpectomy was associated with increased overall mortality (hazard ratio for death [HR], 1.522; 95% confidence interval [CI], 1.317–1.759; p < .001) and cancer-specific mortality (HR, 1.666; 95% CI, 1.319–2.105; p < .001). Similar HRs were derived from the PSMA cohort. However, we found no significant difference in overall mortality for women who underwent repeat lumpectomy followed by radiation therapy (RT) compared with that for those who underwent mastectomy. Moreover, patients with IBTR with small tumors (≤1 cm) who underwent repeat lumpectomy with RT rather than without had similar overall and cancer-specific survival rates to those who underwent mastectomy.

Conclusion

Our investigation suggests that compared with mastectomy, repeat lumpectomy for IBTR is associated with higher overall and cancer-specific mortality under real-world observational conditions. Furthermore, repeat lumpectomy with RT is equivalent to mastectomy with respect to overall mortality and may influence treatment decision making for patients with small IBTR.

Implications for Practice

Although mastectomy has been regarded as the standard treatment for ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery, many patients diagnosed with small and early-detected recurrent tumor might be technically suitable for a less invasive surgical procedure. However, different studies have drawn inconsistent conclusions. The present study is a population-based analysis, which demonstrated the overall unfavorable impact of repeat lumpectomy over mastectomy on survival outcomes for patients with IBTR. However, patients with small IBTR (≤1 cm) that can tolerate radiation therapy may be the optimal candidates for repeat lumpectomy.

Servikal omurganın yapısal ve işlevsel bütünlüğünü travma, dejenerasyon, tümöral ve infeksiyöz hastalıklar bozabilirler. İnstabilite ayrıca, çeşitli nedenlerle yapılan cerrahi girişimlerden sonra da iyatrojenik olarak da görülebilir. Servikal instabilite hafif nörolojik kusurlardan, ağır nörolojik defisitlere hatta ölüme neden olabilecek ciddi bir durumdur. Tedavisi nöral ve vasküler yapıların dekompresyonunu, normal anatomik dizilimin tekrar sağlanmasını ve rijid bir fiksasyonu gerektirir. Uzun süre immobilizasyon, traksiyon ve eksternal fiksatörler gibi ortez kullanımı şeklindeki konservatif tedaviler, bazı olgularda uygulanıyor olsa da gelişen cerrahi ve enstrumantasyon sistemleri günümüzde cerrahi ile sağlanan internal fiksasyonu öne çıkarmıştır. Pedikül vidaları ile son derece güçlü stabilizasyon sağlanır bu nedenle torakolomber omurgada en sık kullanılan enstruman olan pedikül vidalarının son yıllarda servikal bölgede de kullanımına başlanmıştır. İnce pedikül yapısı ve vertebral arterin yakın komşuluğu servikal bölgede pedikül vidalarının kullanımını zorlaştıran faktörlerdir. Komplikasyonsuz bir cerrahi için bölge anatomisinin son derece iyi bilinmesi, vida giriş noktalarının, açılarının, vida genişlik ve derinliklerinin ölçülere uygun şekilde seçilmesi şarttır. Ölçümlerimizde pedikül kalınlıklarının kranio-kaudal yönde arttığını, 3.5 mm vida kalınlığının genel olarak uygun olduğu, pedikül yüksekliklerinin pedikül kalınlıklarından fazla olduğunu gördük. Pedikül transvers açılarını 30-45º arasında ölçtük. Ölçümler hem kişiye hem de ölçülen seviyeye göre farklılıklar göstermektedir. Bu durum, cerrahi öncesi radyolojik yöntemlerle yapılacak bir planlamanın pedikül vidalamasındaki önemini gösterir.

Preparation of human Red Blood Cells for Scanning Electron Microscopy imaging v1
Authors: Anne Balanant Marie
Published: March 2019

SEM imaging can be used to quantify RBC shape. RBCs are sampled from fresh blood samples or from packed RBC units during storage. RBCs are resuspended into PBS to make up 500 μL of solution at 5% haematocrit. RBCs are then fixed by progressively adding a concentrated 2% glutaraldehyde solution in the cell suspension. The cells are incubated for 30 min at RT and in the dark, before being centrifuged and washed in PBS. This fixation protocol was established in order to limit RBC shape changes due to the presence of glutaraldehyde. After fixation, a RBC suspension at 2.5% haematocrit is adhered to coverslips coated with poly-D-lysine. A second fixation step is realised on the adhered RBCs by incubating the coverslips in osmium tetroxide in cacodylate buffer (1%) for one hour. The coverslips are then dried by incubating them in an ascending series of ethanol, then by incubating them with hexamethyldisilizane (HMDS) for 30 min. The HMDS incubation step is repeated twice before the coverslips are dried in open air. Finally, the coverslips are gold coated and imaged with a Zeiss Sigma FESEM.
Modeling of сoncepts of the New Testament by means of morphology and syntax
Authors: Shevchenko Larysa
Published: March 2019

The problem of studying text concepts takes an important place among other types of conceptual studies. The usage of the term "concept" in the study of texts is caused by the need for it for the analysis of text-based principles of the work, identification of author's conceptual priorities, leading themes and ideas, deep text meanings etc. The organization of text's conceptual associations based on mutually related and interrelated elements goes beyond the lexical-semantic sphere. The conceptosphere of the New Testament is represented not only by lexical means, although they are the main building material for its creation. Morphological and syntactic means have a significant place among the concept-forming elements of the text of the New Testament. The study was conducted through the context-based generalization of the representation units of the most significant concepts of the New Testament: "Jesus Christ", "God", "Lord", "Father", "Faith", "Law", "Sin", "Salvation", "Grace", "Kingdom of Heaven", "Gospel", "Victim". Author had used method of field analysis, which is based on the analysis of the means providing the content order and connectivity of conceptual entities. The basis of systematization in conceptual fields is the linkage of key words – representatives of the morphology and syntax concepts and means. They acquire concept-forming properties when they are used in contexts for the formation of a certain conceptual feature and when they are repeatedly used in the text. The analysis of the verbalizers of the concepts, their connections and interaction in the studied work allows to make conclusions about the basic principles and regularities of the conceptualization of reality in the text of the New Testament. This study of its conceptosphere has demonstrated that the elements of its modeling have a significant representation in the spheres of morphology and syntax. The completeness of the reconstruction of an interpretive picture of its verbalization can be ensured by a comprehensive analysis of their conceptual-forming capabilities.

The article is devoted to religious discourse, which is the most specific and complex manifestation of communication units, in which linguistic laws operate according to semantic significance and pragmatically reflect unconventional correlations between morphological and syntactic grammatical categories; critical evaluation of linguopragmatic discursive theoretical studies was carried out; the questions of the modal correlation of reality and assertion in linguistics are covered; imperative as a grammatical category of the verb hasn’t only a predicative character, but also a modal which in religious discourse is represented by an opposite vector of functioning, in comparison with the classical modal split according to the types of relation to reality and modal values ​​through the prism of the category of “speaker's sight”; it is emphasized that the pragmatism of the referencing mechanism in combination with the logical-philosophical approach to understanding the imperative shades of modality are the main means of their functional-semantic analysis and definition in religious discourse; it’s noted that in religious discourse modality is based on the own plot structure of the institution, which is expressed through the pragmatic goal and it’s imperative realization, which ideally creates God and passes through the preacher to the addressee; modal shades of the ordering method in the religious environment are defined; imperative modal shades are differentiated according to the logical and intuitive perception of the religious texts of the researcher due to the force of evading the desired action by the addressee; the religious taxonomy of the imperative based on the principle of physical dispersion of light on the 7 basic spectra is created (order, prohibition, prompt, request, exhort, caveat, prevent, advice, wishes), the combination of which is formed by the strongest core imperative – an order (the least desirable for the fulfillment of the imperative action in greetings , and the biggest one - in prohibition); the absence of the notion of “order” in religious discourse is substantiated; peripheral imperative spectra provided a conceptual essence.
The Generalized Poynting Theorem for the General Field and Solution of the 4/3 Problem
Authors: Fedosin Sergey G.
Published: March 2019

The generalized Poynting theorem is applied to the equilibrium system of particles, both inside and outside the system. The particles are bound to each other by means of the electromagnetic and gravitational fields, acceleration field and pressure field. As a result, the correlation is found between the acceleration field coefficient, the pressure field coefficient, the gravitational constant and the vacuum permittivity. This correlation also depends on the ratio of the charge density to the mass density of the particles inside the sphere. Due to the correlation between the given field coefficients the 4/3 problem is solved and the expression for the relativistic energy of the system is refined.

AbstractThe effects of the application of the graft copolymers (Hydrolyzed starch-g-polyacrylonitrile (HSPAN) and Hydrolyzed starch-g-polyacrylic acid (HSPAA)) on the nitrogen (N) and phosphorus (P) retention capacity of soil was evaluated in this study. Soil nutrient (N and P) retention capacity tests was carried out at three graft copolymers application rates (3.0, 6.0, and 9.0g/kg soil) against a blank soil sample to which graft copolymers was not applied. Diammonium phosphate (DAP) at 0, 100, and 200mg in aqueous solution/kg soil were applied in triplicates. The soil samples were mixed thoroughly and allowed to air-dry. The residual N and P contents of the soil samples were determined and reported as the amounts of nutrients retained as a function of the graft copolymer and DAP application rates. The result of this study has clearly demonstrated the potential of the graft copolymers to alleviate problems related to nutrient loss from the soil media. Leaching of nutrients (N and P) in soil has been found to be reduced to minimal (0.46%N, and 1.13%P) with the application of hydrolyzed graft copolymer and the nutrients are thus available to plant for growth by suction pressure difference.

In this study, TiO2 nanotubes (TNTs) were synthesized via a hydrothermal process and characterized by high-resolution transmission electron microscopy (HR-TEM) images, selected area electron diffraction (SAED) pattern, and photoluminescence (PL) analysis. The NO removal photocatalytic activity of the hydrothermally synthesizedTNTs was surveyed systematically. The hydrothermally synthesizedTNTs have shown an efficient NO photodegradation which is approximately 4 times higher than that of P25 and an excellent photostability under visible light after 5 cycles. Furthermore, reactive radicals mainly involved in the photocatalytic reaction were identified by electron spin resonance (ESR) study, leading to a better understanding of the photocatalytic mechanism of the hydrothermally synthesized TNTs.

Published: March 2019

Background: 2-5% of the pregnancies are complicated by antepartum haemorrhage. About one third of them are due to placenta previa thus contributing to a significant amount of maternal and perinatal morbidity and mortality. In the present times with liberally increasing caesarean section rates, there is a changing trend in the incidence and complications of placenta previa. The objective of this study was to evaluate the obstetrical characteristics and maternal and perinatal outcome of cases of placenta previa.Methods: This was a prospective observational study conducted in the Department of Obstetrics and Gynaecology of JSS Medical College and Hospital, Mysore during the period January 2017 to June 2018.Results: Out of total 13,150 deliveries during this period, placenta previa was observed in 131 cases with an incidence of 1%. Majority belonged to the age group 25-29 years (48.8%). 66% of the cases presented with painless vaginal bleeding as their chief complaint. The major risk factor was previous caesarean delivery seen in 29.8% cases followed by history of abortion in 18.3%. 67% cases had major degree placenta previa. Remaining 33% cases had minor degree. One case was complicated by placenta accrete. Peripartum hysterectomy was performed in 3.1%. Preterm deliveries amounted to 29.8%. Maternal and perinatal mortality were 0.76% and 3.05% respectively. 10.7% cases had Postpartum haemorrhage and 3.8% required ICU admission. 25% neonates required NICU admissions and 10% had RDS.Conclusions: Placenta previa is a prime contributor to substantial maternal and perinatal morbidity and mortality. Early referral to tertiary care centres, anticipation of clinical complications and appropriate measures can avoid grave consequences. Such cases must always be managed at a higher centre with good NICU services and round the clock operation theatre and blood bank facility.

Background: The aim of the study was to evaluate average age of menarche, the pattern and types of menstrual disorders and their relation with BMI, dietary habits, physical exercise and stress.Methods: A cross sectional prospective study was conducted on female medical students during the academic year 2018-2019 at Mallareddy medical college for women, Suraram, Hyderabad, India. The various life style factors including BMI, junk food consumption and physical exercise were factored. Prevalence of each different menstrual abnormality were identified and analyzed by Chi-squire test and p value <0.005 was considered as statistically significant.Results: Study included 255 medical students who had attained menarche without known medical problems. Mean age of menarche was 12.81years. The most frequent menstrual disorders were premenstrual syndrome 192 (75 %), dysmenorrhoea 146 (57 %), and irregular cycle 97(38%). Statistically significant association of Body mass index (BMI) related to premenstrual syndrome (PMS) and dysmenorrhoea was reported (both p<0.05). Similarly, statistically significant association of lack of physical activity had greater risk of premenstrual syndrome and dysmenorrhoea (both p<0.0001). Unhealthy dietary patterns had statistically significant higher risk for dysmenorrhoea (p<0.0001).Conclusions: In conclusion premenstrual symptoms, dysmenorrhoea and menstrual irregularities were more prevalent. Majority of symptoms were stress, pain abdomen, irritability, mood swings. Comprehensive education programs on lifestyle modifications like regular physical activities, promoting healthy eating habits should be emphasised to prevent menstrual abnormalities of young students as early as at school level.

Background: Continuous fetal heart monitoring in all pregnant women in labour has gained prominence in obstetric practice in the recent years. The aim of this study was to emphasize on the role of admission cardiotocography (CTG) in labour as a predictor of foetal outcome in high risk pregnancies.Methods: This was a prospective observational study done on 340 high risk patients admitted in labour with a period of gestation of ≥37 weeks. An admission CTG which consists of a 20-minute recording of FHR and uterine contractions was taken and the foetal outcome was correlated with it. The non-parametric Chi-square test was used for statistical calculations and a p valve of <0.05 was considered to designate statistical significance.Results: The admission CTG was reactive in 69.4% of all patients, equivocal in 22.2% and pathological in 8.4% of the 340 recruited patients. A total of 37.5% of the patients were post-dated followed by 20.6% of pregnancy incuded hypertensive patients. The neonatal outcomes in terms of fetal distress, meconium stained liquor, NICU admission were considerably higher in pathological test. The specificity of the test was 53.3%, and the negative predictive was    86.49%.Conclusions: Admission CTG is a simple, useful screening test and serves as a non-invasive tool in forecasting the adverse foetal outcomes in high risk pregnancies.

Background: The objective is to compare the efficacy of vaginal Misoprostol versus transcervical Foley’s catheter and vaginal Misoprostol.Methods: A prospective study analyzing the comparative efficacy of intravaginal instillation of Misoprostol in two groups (tablet Misoprostol 50mg alone and combination of intracervical Foley’s catheter and tablet Misoprostol 50mg) carried out in the labour room on 300 subjects (150 subjects in each group), from May 2013 to November 2015.Results: The common gestational age at the time of induction was 36-40 weeks and the most common indication was premature rupture of membrane. In both the groups, most of the cases delivered within 12 hours. present results show that statistically significant number of cases delivered vaginally within 12 hours with the group using Misoprostol plus Foley’s catheter as compared to the group using Misoprostol alone. Cesarean section rate was 12.67% in Misoprostol group and 10.67% in Misoprostol plus Foley’s catheter group. Incidence of failure of induction was similar in both the groups. The incidence of babies with Apgar score less than 8/10 at 5 minutes and incidence of early neonatal death were similar in both the groups.Conclusions: Addition of intracervical Foley’s catheter to vaginal Misoprostol for induction of labor in subjects with unfavorable cervices reduces the Induction-Delivery interval without added side effects or complications to the mother and fetus.
