Investor Protection, Stock Liquidity, and Capital Structure
Authors: Pham Chuong Hong , Le Hoang Duc , Dang Hung Quoc , Bui Uyen Tu
Published: July 2020

This paper investigates empirically the impact of stock liquidity and investor protection on corporate capital structure. We predict that stock liquidity has a significantly negative impact on firm leverage and this negative impact is stronger in a country where the investor protection is strong. The sample consists of 2,203 firms listed in the UK, Germany, France, and Italy over the period from 2009 to 2018. Using a firm fixed effects model, we find evidence supporting our prediction. Our results are robust when we use a random effects model model, or when we employ an alternative measure of investor protection. Additionally, we find that an exogenous event that reduced the investor protection could dampen the negative impact of stock liquidity on firm leverage. Our paper suggests that future studies should consider the effects of factors related to the level of investor protection when investigating the relationship between stock liquidity and firm characteristics, such as firms’ default risk.

Published: July 2020

We examine the effect of social media advertising on the operating, financing and investing level of cash flow based on listed banks in emerging economies in Africa. We employ control variables such as board size and financial leverage to control other factors not captured in our model. Results obtained reveal that social media costs aid all levels of cash flow in Ghana and South-Africa. Social media costs in Botswana have a significant impact with operating and financing cash flow and an insignificant effect with investing cash flow. The results obtained from Kenya revealed a significant relationship between the independent variable and the financing and investing cash flow while an insignificant relationship was statistically obtained when social media cost was regressed against the operating level of cash flow. The Tanzanian results reveal a significant impact with the financing and investing level of cash flow but an insignificant value was obtained from the operating level of cash flow. The Nigerian results yielded an insignificant value, from the operating and financing level of cash flow, while investing cash flow generated a significant relationship.

Authors: Fakhrou Abdulnaser A. , Ghareeb Sara A.
Published: July 2020

The present study aimed to explore the anxiety level of the children with autism in Qatar. It aimed to explore whether there is any statistically significant difference between the anxiety levels of the autistic children which can be attributed to (gender, school stage, school type or family type). The researchers adopted a descriptive analytical approach. The sample consists from 250 female and male children with autism. Those children were selected from public and private schools in Qatar. The scale of the present study was developed based on the anxiety scale for children with autism spectrum disorder (ASC-ASD). The latter scale was developed by Rodgers et al. (2016). It consists from 24 items. It collects demographic data about (gender, school stage, school type and family type). The researchers concluded that the anxiety level of the children with autism in Qatar is low. They concluded that there isn’t any statistically significant difference between the anxiety levels of the children with autism which can be attributed to (gender or school stage). They concluded that there are statistically significant differences between the anxiety levels of the children with autism which can be attributed to (the school type or family type). The latter differences are for the favor of the children in private schools. They are for the favor of the children who live in families in which one parent or both parents passed away. The researchers recommend integrating the children with autism into society through engaging those children in extra-curricular activities.
Microvascular nose reconstruction after extended tumor resection.
Authors: Krakowczyk Łukasz
Published: July 2020

Introduction: The nose is the central and probably the most important anatomical region of the face. Reconstructive surgery after tumor resection in this anatomical region requires from the surgeon knowledge of the anatomy, due to the three-dimensional shape and variety of tissues.
Materials and methods: In the years 2010-2019, 48 patients were treated in the Oncological and Reconstructive Surgery Clinic for extended nasal tumors , who required the use of free microvascular flaps after resection for functional and aesthetic supply of anatomical structures of the nose.
Results: In 48 patients, a total of 92 free microvascular flap were used for nasal reconstruction including: radial forearm free flap in 24 patients, radial forearm free flap with radial bone in 14 patients, auricle free flap in 16 patients, radial forearm free flap in combination with auricle free flap in 7 patients, double auricle free flap in 6 patients, radial forearm free flap in combination with double auricle free flap in 4 patients. Total necrosis of the free flap was noted in 4 cases, partial in 6 patients.
Conclusions: Presented surgical techniques using the microvascular free flaps constitute a recognized method of treatment in the world and should be used in everyday surgeon practice.
Discussion: In the reconstructive nose surgery after extended tumor resections due to cancer, there are no uniform treatment standards and algorithms . The surgeon is often dependent on his knowledge, skills and creative thinking . Presented results in this article allows to obtain optimal functional and aesthetic effects.
Long-term results of a hearing test in patients
operated for chronic otitis media
Authors: Boroń Aleksandra , Składzień Jacek
Published: July 2020

 Introduction: Chronic otitis media is characterized by tympanic membrane perforation and conductive hearing loss. In the active form of this disease, there will also be periodic or permanent otorrhea. With a number of surgical techniques available depending on intraoperative findings, otosurgery is the treatment of choice in such cases, the extent of which depends on the type and extent of the pathological changes.
Material and Method: We carried out an analysis of 79 patients with chronic otitis media undergoing surgery at the Department of Otolaryngology, Jagiellonian University Medical College in Kraków between 2005 and 2014. Total audiometry was used as a part of hearing assessment, before the surgery, 6 months after the surgery and in the distant 10-year observation period. In addition, each patient completed the questionnaire and was examined by an otolaryngologist.
 Results: The analysis included 79 patients operated on due to chronic otitis media. The mean bone conduction (for frequencies 500,1000 and 2000 Hz) before surgery was 31.8 dB, it did not differ significantly (p = 0.355) after 6 months after surgery (32.8 dB), while it significantly increased (p < 0.001) in a distant 10-year control of 43.4 dB. The mean air conduction (for frequencies 500, 1000 and 2000 Hz) before the procedure was 57.6 dB, it significantly improved in the early control by 50.5 dB, at p < 0.001. In long-term follow-up it increased again to 61.3 dB and was significantly different from the early postoperative period (p < 0.001). The mean air-bone gap for frequencies 500, 1000 and 2000 Hz before surgery was on average 26.4 dB, it was significantly (p < 0.001) reduced in the postoperative period by 17.6 dB. The level of air-bone gap remained at a similar level in distant control.
Conclusions: (1) A completely preserved ossicular chain in the absence of active chronic otitis media is the best prognosis for stable hearing improvement over the years with normal inner ear function; (2) Reoperation worsens the long-term results of a hearing test compared to the first operation.
Synchronous rectal prolapse and midgut volvulus
presenting as complete small bowel gangrene
Authors: Agarwal Nitin , Kumar Peeyush , Gupta Nikhil
Published: July 2020

Introduction: Adult midgut malrotation is very rare. The presentation in adults is mostly subtle; the diagnosis is often made on imaging.
Case report: A 32-year-old man presented with a 3-day history of an irreducible painful mass protruding per rectum, followed by abdominal pain and constipation. The patient was febrile and toxic, with marked signs of peritonitis and complete fullthickness irreducible rectal prolapse. Abdominal radiographs showed multiple air-fluid levels. A diagnosis of irreducible rectal prolapse with intestinal obstruction was made. Laparotomy revealed complete small bowel gangrene, abnormal rotation of the small bowel 180° around the mesenteric root, hypermobile duodenojejunal flexure and ileocaecal junction and an abnormally mobile caecum lying in the central abdomen. Abnormal mobility of the sigmoid colon with a large mesocolon, and a large irreducible rectosigmoid intussusception, was also noted. Our patient is probably the first case in literature, which may prompt awareness of simultaneously-occurring disorders of fixation, and preventive steps.

Published: July 2020

The aim is to assess the relationship of Anterior Ethmoid Artery with the Upper Attachment of the Uncinate Process and their relation with the Lateral Lamella of the Cribriform Plate in multiplanar reconstructions (i.e. coronal, axial and sagittal) of Computed Tomography. We measured the depth of the olfactory fossa, the length of the LLCP and determined the most superior attachment of the uncinate process, which designates boundaries of the frontal recess anteriorly, laterally and medially [20,22]. Methods: All CT examinations were performed using the 320-detector Aquilion ONE CT Scanner (Canon Medical Systems, Otawara, Japan). Axial, coronal,sagittal reconstructions were performed by using dedicated workstation software (Vitrea Enterprice Siute, Version 6.7; Vital Images, Minnetonka USA). The Statistica 13 software was used for the analysis, results were considered statistically significant at the level of p<0,05. Results: The most frequent types of Uncinate Process according to Landsberg- Friedman criteria in group of mens are: type I-30,77%,type II-30,77%, type III-26,92%, type VI-7,69%, type V-3,85%, type IV-0% respectively. In women's group: type III-44,12%,type II-32,35%, type I-8,82%,type V-8,82%, type IV-5,88%, type VI-0%. The median LLCP length in the anterior-posterior dimension measures 13 mm i. e. Yenigun type II on the both sides. The median value of depth in the superior-inferior dimension of the LLCP in the ethmoid roof is 5 mm i.e. Keros type II on both sides. The mean distance between Anterior Ethmoid Artery and Upper Attachment of the Uncinate Process measures approximately 9,73 mm and 9,16 mm on the right and left side respectively. Conclusions: The assessment of the AEA, UAUP and configuration of the anterior skull base on CT multiplanar reconstructions contribute to optimazing the results of frontal sinus surgery.
An unusual case of a tuberculous granuloma of the liver
presenting thirteen years after intravesical BCG
– therapy for bladder cancer
Authors: Szczęsny Wojciech , Szylberg Łukasz , Słupski Maciej , Marszałek Andrzej , Szmytkowski Jakub
Published: July 2020

The authors present the case of a female patient with a tumor of segment VII of the liver, which was postoperatively identified as a tuberculous granuloma. The patient was admitted for elective surgery for a liver tumor, which had been diagnosed a few months before. Computed tomography and nuclear magnetic resonance were performed, based on which focal nodular hyperplasia was suspected. Thirteen years prior to admission the patient had undergone a transurethral resection of superficial bladder carcinoma, followed by adjuvant intravesical Bacillus Calmette-Guérin (BCG-therapy). Upon surgery, segment VII of the liver was resected; postoperative course was uneventful. After the identification of granuloma, the patient was referred to a phthysiatric clinic for further diagnostics and treatment. The authors have deemed this case worthy of reporting primarily due to the exceptionally long period between the completion of BCG therapy and the onset of hepatic tumor.

Tradition und Fortschreibung bei Ibn Rušd
Authors: Kurnaz Serdar
Published: July 2020

This study portrays the unique philosophical approach of Ibn Rushd to systematising Islamic law flexibly in order to solve the problems Muslims experience in daily life. His approach allows for a new perspective in the discourse on how to update Islamic law for contemporary times and how norms are qualified as being Islamic.
Taking the prohibition of usury as an example, this study scrutinises Ibn Rushd’s approach and compares it with others from Muslim legal scholarship. For this purpose, the introduction and the chapter on usury in his juristic work Bidāyat al-mujtahid have been translated and commented on, with his approach analysed and the sources that he consulted identified.
Die Durchsetzung kapitalmarktrechtlicher Vorschriften mittels Privatrechts
Authors: Schwarzer Eva-Maria
Published: July 2020

Das Werk untersucht den Beitrag des Privatrechts zur Durchsetzung kapitalmarktrechtlicher Vorschriften.

Das deutsche Kapitalmarktrecht setzt hinsichtlich der Durchsetzung der kapitalmarktrechtlichen Verhaltenspflichten bislang in erster Linie auf das öffentlich rechtliche Aufsichtsrecht sowie das Strafrecht. Das alternative Steuerungs- und Sanktionsinstrument „Privatrecht“ rückt in der EU erst seit einigen Jahren in den Mittelpunkt der wissenschaftlichen Betrachtung.

Das Werk analysiert, ob das Privatrecht de lege lata bereits einen Beitrag zur Durchsetzung der Verhaltensvorschriften des Sekundärmarktes leistet und ob de lege ferenda privatrechtliche Regelungen erwogen werden sollten oder gar erlassen werden müssen.
Einstandspflichten und gestörte Gesamtschuld in der Vorstandshaftung
Authors: Groh Jakob
Published: July 2020

Die Haftung von Vorstandsmitgliedern ist meist kein Solokonzert, sondern ein Ensemble mit Mitgliedern des Aufsichtsrats und Arbeitnehmer/-innen der Aktiengesellschaft. Die Arbeit untersucht, wie dieses Zusammenspiel stimmig zu arrangieren ist und wirft dabei bislang kaum diskutierte Fragen einer gemeinsamen Haftung auf: In welchem Haftungsverhältnis stehen die Beteiligten? Wie korrelieren die gesamtschuldnerische Organhaftung und ein möglicher Mitverschuldenseinwand? Zu wessen Lasten gehen Störungen aufgrund des Arbeitnehmerhaftungsprivilegs? Bei der Suche nach dogmatisch stimmigen Antworten stellt sich der Autor nicht selten gegen die herrschende Meinung und versucht dabei, auch die Bedürfnisse der Praxis nicht aus den Augen zu verlieren.

The author analyses 1075 articles from eleven daily newspapers, traces the journalists’ processes of weighing up different interests by means of qualitative guided interviews and poses the fundamental question of the ethical standards of journalistic activities.

Through this book, Heike Haarhoff, who holds a doctorate in media studies and has been a newspaper editor for many years, closes a gap in the field of journalism research.
Multiple-Image Fusion Encryption (MIFE) Using Discrete Cosine Transformation (DCT) and Pseudo Random Number Generators
Authors: Mariel Heucheun Yepdia Lee , Tiedeu Alain , Lachiri Zied
Published: July 2020

This chapter proposes a new multiple-image encryption algorithm based on spectral fusion of watermarked images and new chaotic generators. Logistic-May (LM), May-Gaussian (MG), and Gaussian-Gompertz (GG) were used as chaotic generators for their good properties in order to correct the flaws of 1D chaotic maps (Logistic, May, Gaussian, Gompertz) when used individually. Firstly, the discrete cosine transformation (DCT) and the low-pass filter of appropriate sizes are used to combine the target watermarked images in the spectral domain in two different multiplex images. Secondly, each of the two images is concatenated into blocks of small size, which are mixed by changing their position following the order generated by a chaotic sequence from the Logistic-May system (LM). Finally, the fusion of both scrambled images is achieved by a nonlinear mathematical expression based on Cramer’s rule to obtain two hybrid encrypted images. Then, after the decryption step, the hidden message can be retrieved from the watermarked image without any loss. The security analysis and experimental simulations confirmed that the proposed algorithm has a good encryption performance; it can encrypt a large number of images combined with text, of different types while maintaining a reduced Mean Square Error (MSE) after decryption.
Respiratory Health Risks from Exposure to Dust from Soybean and Its Products
Authors: J. Mason Howard
Published: July 2020

Soybean and its processed forms have become an increasingly important part of agriculture, where they are widely used as an animal feedstuff and in an extensive range of human food products. This entails transportation from producer countries, largely the USA and South America, to importer destinations such as the EU and China. Soya is recognised as a dietary allergen, containing a number of identified allergenic proteins. Inhaled soya dust generated by occupational activities also causes respiratory health problems. Reports of “asthma epidemics” in harbour cities identified ill health in the community but were related to occupational activities of unloading/loading bulk soya without appropriate dust control measures. Inhaled allergens in already-sensitised individuals can cause a range of allergic symptoms in the eyes, nose, and respiratory tract, including occupational asthma (OA). Soybean dust can also cause health problems related to lung irritancy. Endotoxin and fungal contamination associated with soya are also potential respiratory hazards. This chapter reviews published data on ill health and symptoms from airborne exposure to allergens in dust from soybean and derivative products and the levels of exposure to dust and major allergens from a range of occupational activities. Other potential health hazards associated with soybean, such as endotoxin and fungal contamination, are also highlighted.

Nanocomposite Materials
Authors: Sen Mousumi
Published: July 2020

Nanocomposites are the heterogeneous/hybrid materials that are produced by the mixtures of polymers with inorganic solids (clays to oxides) at the nanometric scale. Their structures are found to be more complicated than that of microcomposites. They are highly influenced by the structure, composition, interfacial interactions, and components of individual property. Most popularly, nanocomposites are prepared by the process within in situ growth and polymerization of biopolymer and inorganic matrix. With the rapid estimated demand of these striking potentially advanced materials, make them very much useful in various industries ranging from small scale to large to very large manufacturing units. With a great deal to mankind with environmental friendly, these offer advanced technologies in addition to the enhanced business opportunities to several industrial sectors like automobile, construction, electronics and electrical, food packaging, and technology transfer.
Nevus Lipomatosus Cutaneous Superficialis: A Case Report and Literature Review
Authors: Yeak Raymond Dieu Kiat , Yap Yee Yee , Nasir Nizlan M.
Published: July 2020

Introduction: Nevus lipomatosus cutaneous superficialis (NLCS) is uncommon and can be encountered in various medical specialties. In this study, we report a rare case of solitary pedunculated nevus lipomatosus cutaneous superficialis in a middle-aged female patient and highlight its clinical and histopathological features. Case Presentation: A 43-year-old Malaysian female patient presented to our center with a 2-cm long and 1-cm wide solitary, flesh-colored nodule over the anterolateral aspect of her thigh. Excisional biopsy was performed, and the histopathology report showed NLCS. There are three types of NLCS, namely the solitary, multiple, and generalized forms. The etiology of NLCS is usually idiopathic, with no gender or familial preponderance. NLCS is usually misdiagnosed and should be differentiated from nevus sebaceous, connective tissue nevus, neurofibroma, lymphangioma, hemangioma, and focal dermal hypoplasia (also known as Goltz syndrome). Conclusions: In conclusion, NLCS is rare and benign condition, which should be differentiated from other malignant skin conditions as it is commonly misdiagnosed. Therefore, physicians and surgeons should be aware of its clinical and histopathological features.

Nuvem : Plataforma : Extração
Authors: Neto Moysés Pinto
Published: July 2020

O presente texto traça um esboço de mapeamento cognitivo ou análise de conjuntura, inspirado nas estratégias de Fredric Jameson e Lawrence Grossberg, respectivamente, acerca da condição contemporânea quanto à emergência do “nevoeiro”. O papel central das plataformas digitais − em especial pela tecnologia das nuvens − gera um ambiente em que há aparente transparência, mas código-fonte e algoritmo permanecem ocultos. Tem-se, assim, uma sensação de penumbra, nevoeiro ou trevas descritas por autores como James Bridle, Guilherme Wisnik, Benjamin Loveluck, entre outros. A partir desse cenário, pensa-se a operação translúcida levada a cabo pelas plataformas, baseado em Nick Srnicek, Shoshana Zuboff e Jaron Lanier, como uma forma sutil de extrativismo de dados, aproximando-a dos estudos sobre o Capitaloceno, de Jason Moore. Finalmente, propõe-se que o fenômeno bummer, mal-estar relacionado à captura de dados pelas plataformas, está ligado à extração da própria identidade como matéria-prima, nomeando o extrativismo identitário e tomando como sua face material o mal-estar no corpo.Palavras-chave: Computação em nuvem.

Published: July 2020

O Contorno Norte de Maringá (PR) é uma obra de intervenção urbana, realizada com recursos do Programa de Aceleração do Crescimento, PAC. Devido à localização da obra ser na divisa entre as cidades de Maringá e Sarandi, buscamos, neste estudo, compreender quais foram as influências dessa configuração na dinâmica dos espaços ocupados no eixo conurbado dos municípios. A análise dos dados obtidos permitiu avaliar que o Contorno Norte facilitou o movimento dos negócios, a viabilização da entrada e saída de caminhões, bem como a agilidade nas entregas. Ambos os municípios se beneficiaram da obra, em relação ao favorecimento de novos empreendimentos, embora haja relatos de trânsito intenso na divisa entre Maringá e Sarandi. O fluxo de veículos na Avenida Colombo apresentou melhora após a finalização do Contorno, apesar de terem sido constatadas reclamações quanto à localização da obra, posicionada na entrada/saída de duas cidades e em grande parte do entroncamento do Contorno Sul, o que torna confuso o acesso às empresas localizadas na Avenida Colombo e favorece a ocorrência de acidentes de trânsito. Concluiu-se que a obra não fomenta impactos negativos para os empreendimentos e permitiu maior integração, não somente entre as cidades em questão, mas à região.Palavras-chave: Conurbação.

Impact of cytomixis on the microspogenesis and formation of unreduced pollen grains in monocots
Authors: Kravets E. A. , Plohovskaya S. H. , Horyunova I. I. , Emets A. I. , Blume Ya. B.
Published: July 2020

Aim. Despite significant progress in the investigation of cytomixis its functional role and effect on the course of meiosis as well as mechanisms of 2n pollen grains formation is still not completely clear. We have studied the destination of cytomictic chromatin as well the mechanisms of unreduced microspores formation in species of monocots with spontaneous cytomixis. Methods. Light and fluorescent microscopy. Results. The cytomictic chromatin forms additional meiotic chromosomes in the recipient microsporocytes. Many of these meiotic chromosomes undergo rearrangement and fragmentation but retain their bivalent organization. Conclusions. Cytogenetic anomalies of microsporogenesis caused by activation of cytomixis in prophase may reflect meiosis stabilization mechanisms by assimilation and adaptation or diminution and reutilization of the introduced DNA. The main mechanism of polyploidization of microsporocytes and pollen grains in studied monocots is the restitution of the first meiotic division via the formation of a meta-anaphase 1 block.Keywords: cytomixis, microsporogenesis, additional (recipient) chromosomes, meta-anaphase 1 block, Lilium croceum Chaix., Allium cepa L., Allium fistulosum L.

Authors: Antonenko S. V. , Kravchuk I. V. , Gurianov D. S. , Telegeev G. D.
Published: July 2020

Aim. Impact of domains of Bcr in oncogenic effect associated with Bcr-Abl remains unclear. Investigation of protein-protein interactions can be one of the effective ways to reveal those molecular events that alter normal cellular processes and cause malignant transformation. Previous research showed that USP1, Cortactin and Hsp27 may interact with PH domain. To confirm interactions and to study their biological consequences, genetic constructs for expression and microscopy should be created. Methods. Various standard molecular cloning techniques and expression in E. coli strain Rosetta. Results. Several DNA constructs have been created (pBluescriptSKII(+)+USP1, pFastFT-N1-CTTN, pMediumFT-N1-CTTN, pSlowFT-N1- CTTN and pET42a-hsp27). Effective bacterial expression of Hsp27 has been performed. Conclusions. All DNA constructs can be effective instruments to study biological role of interactions between PH domain of Bcr and USP1, Cortactin, Hsp27.Keywords: PH domain, Bcr-Abl, USP1, Cortactin, Hsp27.

Also, the use of different wavelength combinations can influence plants grows and development. The aim of the present work was to study the monochrome blue LED lighting effect on the morphologic characteristics of some medical plants during in vitro cultivation. Methods. Digitalis pur-purea L., Aerva lanata L. Juss. ex Schult. and Cathranthus roseus G. Don in vitro cultivated plants were used for monochrome blue LED lighting effect estimation. Spectrometric methods of photosynthetic pigments and flavonoid content estimation were used. Results. In vitro plants grows with 440–460 nm LED lighting causes adaptive morpho-physiological changes with pigments and flavonoids content decrease. An increase in shoots formation, plant grows deceleration and interstices shortening were also found. Conclusions. Obtained results suggest insufficiency of mono-chrome LED lighting and the need of optimal spectral composition determination for successful plants cultivation. Keywords: LED lighting, Digitalis purpurea L., Aerva lanata L. Juss. ex Schult., Cathranthus roseus G. Don, morpho-physiological changes.

Aim. The aim was to estimate the efficiency of cell-containing and non-cellular dermal coverages in animal model in vivo. Methods. We carried out the application of gel wound coverages with three different cell lines and cultural medium conditioned by these cells on the third degree burns of ICR line mice. In the control group animals were treated with fresh medium-containing gel. Photo fixation of burn wound status was carried out once a day. The results were estimated by ANOVA approach. Results. There was a statistically significant difference of burn wounds development and healing within three experimental groups treated with cell suspensions of different lines. Cell-free gels with media conditioned by these cells were shown to be effective as well. Conclusions. It has been shown the dependence of wound healing properties of coatings containing cells from the origin of these cells. The effectiveness of these coverages is supposed to be intermediated by biologically active substances secreted by the cells.Keywords: burn wound, dermal equivalent, stem cells, skin equivalent, skin substitute, tissue engineering.

Aim. We have researched probabilistic relations between genome size and two adaptability indices in eleven genotypes revealed in seeds germ of Deschampsia antarctica E. Desv. which has different genome size under standardized cultivation condition in vitro. Methods. We have used biochemical method for determination of flavonoid contents in plant leaves and flow cytometry analysis for determination of genome size in plant leaves. Results. Eleven genotypes of Deschampsia antarctica with different genome size have been researched by three data rows. Probabilistic scheme have been created and analyzed for all researched genotypes. Conclusions. The Deschampsia antarctica genome size or karyotype changes have been shown to have effect on its probabilistic relations with flavonoids content and leaf length. Mechanisms of such relations is required a detailed research. Keywords: Deschampsia antarctica, genome size, leaf length, flavonoids.
Novel tools for the prediction of promoters in plants and bacteria
Authors: Shahmuradov I. A.
Published: July 2020

Aim. The computational search for promoters remains an attractive problem in bioinformatics. Despite the attention it has received for many years, the problem has not been addressed satisfactorily. These studies were aimed to develop novel computer tools for prediction of promoters (transcription start sites, TSSs) in plants and bacteria. Results. Two novel tools for prediction of RNA polymerase II promoters in plants (TSSPlant) and bacteria (bTSSfinder) have been developed. TSSPlant achieves significantly higher accuracy compared to the next best promoter prediction program for both TATA and TATA-less promoters; it is available to download as a standalone program at http://www.cbrc.kaust.edu.sa/download/. bTSSfinder predicts promoters for five classes of σ factors in Cyanobacteria (σA, σC, σH, σG and σF) and for five classes of sigma factors in E. coli (σ70, σ38, σ32, σ28 and σ24). Comparing to currently available tools, bTSSfinder achieves highest accuracy. bTSSfinder is available standalone and online at http://www.cbrc.kaust.edu.sa/btssfinder. Conclusions. To date, TSSPlant and bTSSfinder are most accurate promoter predictors in plants and bacteria, respectively.

Keywords: transcription, RNA polymerase, promoter, TSS, promoter prediction.

A Case of unexpected Fatal Hemoperitoneum in Non-severe Acute Pancreatitis
Authors: Choi Seong Jin , Yoon Eileen L. , Lee Jong Ho , Kim Kye Yeon , Choi Soo In , Choi Won-choong
Published: July 2020

Acute pancreatitis (AP) severity is determined by associated organ failure (OF). However, enzymatic erosion of peripancreatic vessels can lead to life-threatening hemoperitoneum in clinically non-severe AP without OF. We herein report a case of unexpected hemoperitoneum which developed in a patient with clinically resolving AP without OF. A 36-year-old woman with alcohol use disorder presented with resolving epigastric pain and sustained abdominal distension of 2 weeks’ duration. Ranson’s score on admission was 1 and Computed tomography (CT) revealed non-necrotic AP with peripancreatic fluid collection. She showed sudden hypotension with an abrupt decrease in serum hemoglobin within 24 hours after admission. She was suspected to have an acute hemoperitoneum associated with venous bleeding from AP based on repeated CT. Venous bleeding from the splenic branch was ligated during surgery. The possibility of bleeding at the pancreatic bed should be considered even if the pancreatitis is not severe.
Klebsiella pneumoniae-induced Liver Abscess Complicated with Septic Pulmonary Embolism in a Non-diabetic Adult
Authors: Lim Byung Hun , Lee Song-I
Published: July 2020

A 72-year-old non-diabetic man was admitted to the intensive care unit because of liver abscess, cholecystitis, and septic shock. He underwent percutaneous catheter drainage and received intravenous antibiotics. Shock was improved, and the patient’s fever subsided. Klebsiella pneumoniae was isolated in blood and bile cultures. However, he suddenly developed dyspnea and oxygen desaturation. Chest computed tomography scan revealed multifocal ground-glass opacities with consolidation with peripheral preponderance. Appropriate antibiotic therapy was provided for 2 weeks. The patient recovered fully, and cholecystectomy was then performed. Herein, we report a case of K. pneumoniae-induced liver abscess complicated with septic pulmonary embolism in a non-diabetic patient.
