Exploring STEM postsecondary instructors’ accounts of instructional planning and revisions
Authors: Erdmann Robert , Miller Kathryn , Stains Marilyne 
Published: February 2020

Abstract
Background
Local and national initiatives to improve the learning experiences of students enrolled in Science, Technology, Engineering, and Mathematics (STEM) courses have been on-going for a couple of decades with a heightened momentum within the last 10 years. However, recent large-scale studies have demonstrated that transmission of information is still the primary mode of instruction in STEM courses across the undergraduate curriculum. The limited impact of instructional change reform efforts can be partly explained by the one-sided focus of educational research on the development of evidence-based instructional practices and production of evidence demonstrating their impact on student learning. This has been done at the expense of understanding faculty members’ instructional practices and mindsets about teaching and learning that underlie their practices. This study addresses this gap in the literature by characterizing STEM instructors’ instructional intentions and reflections on their teaching performance for a week of instruction. Data was collected through semi-structured interviews with 42 STEM faculty members from one doctorate-granting institution in the USA.

Results
STEM instructors in this study had teacher-centric mindsets with respect to their instructional planning (e.g., content-focused learning goals, lecture is seen as an engagement strategy). We found that these instructors mostly saw formative assessment tools as engagement strategy rather than tools to monitor student learning. Reflections on their level of satisfaction with their week of teaching focused heavily on content coverage and personal feelings and minimally considered student learning. Finally, we found that pedagogical discontent was not a driver of planned course revisions.

Conclusions
This study identifies mismatches between STEM instructors’ teaching mindsets and current approaches to instructional change. STEM instructors in this study paid minimal attention to student learning when considering course-level revisions and many of their reflections were anchored in their personal feelings. However, instructional reform strategies often attempt to convince faculty of a new approach by demonstrating its impact on student learning. The misalignment identified in this study further highlights the need to better characterize STEM instructors’ cognition around teaching so that reform efforts can better meet them where they are.

Abstract
Background
Granular cell tumors (GCT) in the gastrointestinal tract are rare. Herein, we describe a case of a gastric GCT diagnosed preoperatively by endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB) and successfully resected by single-incision laparoscopic surgery (SILS).

Case presentation
A 46-year-old Japanese woman had a tumor located in the angle of the stomach that was approximately 1.5 cm in diameter. Abdominal computed tomography (CT) revealed a submucosal tumor (SMT), which was finally diagnosed as a gastric GCT using EUS-FNAB. The tumor was not identified by CT 1 year and 4 months before diagnosis; therefore, because there was a possibility that the tumor was malignant, we performed surgical wedge resection using SILS. The patient had an uneventful recovery postoperatively and was discharged without complications 3 days after surgery. The tumor was pathologically diagnosed as a benign GCT that remained within the muscular layer. No recurrence or complications have occurred in the first 16 months since the surgery.

Conclusion
Because gastric GCTs are generally benign and are rarely associated with lymph node metastasis, SILS seems to be a safe and feasible surgical approach for treating GCTs.
Multiple level anterior cervical discectomy and fusion versus posterior laminectomy for the management of multilevel cervical spondylotic myelopathy: clinical and radiological outcome
Authors: Ahmed Omar El Farouk , Galal Ahmed 
Published: February 2020

Abstract
Background
Though both anterior and posterior approach are used for the management of multilevel cervical spondylotic myelopathy (CSM), the choice between both approaches remains to be of considerable debate.

Aim of the work
The aim of the study was to evaluate the clinical and radiographic outcomes of patients with multiple level CSM who underwent posterior laminectomy (PL) versus anterior cervical discectomy and fusion (ACDF).

Methods
This is a retrospective comparative study of 30 patients, with multiple level CSM managed by the authors, either by PL (n = 15) or ACDF (n = 15). Clinical outcome was assessed at 1, 3, 6, and 12 months postoperatively using the modified Japanese Orthopedic Association scale (mJOA) while the postoperative radiographic changes represented by the Cobb’s angle variation was recorded at 12 months postoperatively and compared with preoperative values. Also, the incidence of postoperative complications and neurological deterioration was recorded and studied between the two groups. Study duration was for 2 years from December 2014 to December 2016.

Results
Both the ACDF and PL groups showed an improvement in the mJOA score mean value at 1 year after surgery in comparison with the preoperative evaluation data; however, on comparing between both groups at 1 year postoperatively, the median percent of increase in mJOA score was significantly higher in the ACDF group compared with the PL group (33.3% vs 22.2% respectively). On the other hand, the Cobb’s angle percent of change 1 year after surgery showed a median percent of increase of 18.7% in the ACDF group in contrast to a median decrease of − 11.1% in the PL group which was statistically significant. Minimal complications were reported in both groups.

Conclusion
Both PL and ACDF are effective modalities for the surgical management of multilevel CSM showing good clinical outcome; however, when compared with the posterior approach, there was a statistical significant difference favoring ACDF regarding the median percent of increase in mJOA score and the postoperative Cobb’s angle improvement.

ABSTRACT
Aerial organs of plants, being highly prone to local injuries, require tissue restoration to ensure their survival. However, knowledge of the underlying mechanism is sparse. In this study, we mimicked natural injuries in growing leaves and stems to study the reunion between mechanically disconnected tissues. We show that PLETHORA (PLT) and AINTEGUMENTA (ANT) genes, which encode stem cell-promoting factors, are activated and contribute to vascular regeneration in response to these injuries. PLT proteins bind to and activate the CUC2 promoter. PLT proteins and CUC2 regulate the transcription of the local auxin biosynthesis gene YUC4 in a coherent feed-forward loop, and this process is necessary to drive vascular regeneration. In the absence of this PLT-mediated regeneration response, leaf ground tissue cells can neither acquire the early vascular identity marker ATHB8, nor properly polarise auxin transporters to specify new venation paths. The PLT-CUC2 module is required for vascular regeneration, but is dispensable for midvein formation in leaves. We reveal the mechanisms of vascular regeneration in plants and distinguish between the wound-repair ability of the tissue and its formation during normal development.

Published: February 2020

ABSTRACT
Pluripotent stem cells hold great potential for regenerative medicine. Increased replication and division, such is the case during regeneration, concomitantly increases the risk of adverse outcomes through the acquisition of mutations. Seeking for driving mechanisms of such outcomes, we challenged a pluripotent stem cell system during the tightly controlled regeneration process in the planarian Schmidtea mediterranea. Exposure to the genotoxic compound methyl methanesulfonate (MMS) revealed that despite a similar DNA-damaging effect along the anteroposterior axis of intact animals, responses differed between anterior and posterior fragments after amputation. Stem cell proliferation and differentiation proceeded successfully in the amputated heads, leading to regeneration of missing tissues. Stem cells in the amputated tails showed decreased proliferation and differentiation capacity. As a result, tails could not regenerate. Interference with the body-axis-associated component β-catenin-1 increased regenerative success in tail fragments by stimulating proliferation at an early time point. Our results suggest that differences in the Wnt signalling gradient along the body axis modulate stem cell responses to MMS.
eHealth technologies and the know-do gap: exploring the role of knowledge mobilisation
Authors: Asthana Sheena , Sheaff Rod , Jones Ray , Chatterjee Arunangsu 
Published: February 2020

Background: eHealth technologies are widely believed to contribute to improving health and patients’ experience of care and reducing health system costs. While many studies explore barriers to and facilitators of eHealth innovation, we lack understanding of how this knowledge can be translated into workable, practicable and properly resourced knowledge mobilisation (KM) strategies.
Aims and objectives: This paper describes the aims, methods and outputs of a large European Union funded project (eHealth Productivity and Innovation in Cornwall and the Isles of Scilly (EPIC)) to support the development of a sustainable innovation ecosystem in Cornwall and the Isles of Scilly, in order to explore how knowledge mobilisation activities can help bridge the know-do gap in eHealth.
Conclusions: Preparatory knowledge sharing, linkage making and capacity building are necessary preliminaries to co-production, with an emphasis on capturing the uses to which patients, carers and health workers want to put new technologies rather than promoting new technology for its own sake. Financial support can play a key role in supply-side dynamics, although the contextual and organisational barriers to eHealth innovation in England should not be underestimated.

Visceral scalloping in pancreatic ascites: An uncommon manifestation of pancreatitis
Authors: Kumar Antriksh , Rana Atul , Singh Anupam K , Gupta Pankaj , Singh Harjeet , Sharma Vishal 
Published: February 2020

AbstractScalloping of visceral organs like liver and spleen can cause certain peritoneal diseases. It has usually been described with pseudomyxoma peritonei and peritoneal carcinomatosis. Occasionally, it has also been described with certain benign conditions like peritoneal tuberculosis. We describe visceral scalloping in setting of pancreatic diseases. We believe that pancreatic fluid collections exert significant pressure on the visceral organs to result in scalloping of the visceral surfaces.

Published: February 2020

En los últimos años, el distrito de Huánuco ha presentado un crecimiento poblacional de 1.05%, mediante un asentamiento forzoso sobre áreas inestables, incrementando la vulnerabilidad frente a eventos extremos. La forma de la superficie terrestre puede considerarse como resultante de un sistema evolutivo dentro de escalas de tiempo. Por tanto, se analizó por medio del procesamiento digital de imágenes, el volumen de la remoción en masa empleando imágenes de satélite ALOS PALSAR (2006-2019) y Landsat 5 EMT y 8 OLI (1987-2018), para establecer una relación entre la evolución del paisaje y la ocurrencia de deslizamientos por medio de perfiles topográficos.
Finalmente, se logró demostrar la diferencia entre medias de la evolución del deslizamiento de la quebrada Tingoragra en el distrito de Huánuco (2006-2019), según la clasificación de intensidad en función del volumen por deslizamientos (222,129,497 m³) para establecer un análisis del riesgo.
Genotipificación por RAPD-PCR de aislados de Yersinia ruckeri procedentes de truchas arcoíris (Oncorhynchus mykiss) de la sierra del Perú
Authors: Mesías V. Fernando , Serrano-Martínez Enrique , Llanco A. Luis 
Published: February 2020

El objetivo del presente estudio fue identificar genotipos de Y. ruckeri, según su procedencia, mediante RAPD-PCR. Se tomaron muestras asépticas de bazo y riñón de truchas arcoíris (Oncorhynchus mykiss) con signos clínicos de yersiniosis, provenientes de piscigranjas de cuatro departamentos (Junín, Lima, Ancash y Puno) del Perú. Las cepas fueron cultivadas en agar tripticasa de soya a 25 °C por 24 horas y la identificación presuntiva de las colonias sospechosas de corresponder a Y. ruckeri se hizo mediante tinción Gram y pruebas bioquímicas de oxidasa y catalasa. Luego, se confirmó la identidad de Y. ruckeri por PCR. Se obtuvieron 63 aislados de Y. ruckeri y se analizaron mediante RAPD-PCR. El dendograma de diversidad genética agrupó a todos los aislados en un clúster, estrechamente relacionadas con la cepa control Y. ruckeri ATCC 29473 (96% de similitud). También se observó que todos los aislados eran genéticamente idénticos (clones). Se sugiere que las cepas podrían tener un origen común debido a que tuvieron diferentes procedencias geográficas y elevada similitud entre ellos.

Se evaluó el efecto de la adición de metil-β-ciclodextrina cargada de colesterol (CLC) sobre las características microscópicas del semen refrigerado/descongelado de carnero. Se emplearon cuatro carneros Asblack de 1-2 años. Se usaron 30 eyaculados divididos en grupos de tres alícuotas a los que se agregó CLC (0, 1 y 2 mg de CLC/120 millones de espermatozoides, T1, T2 y T3, respectivamente) a 22 °C y fueron incubados por 15 minutos. Las muestras luego fueron refrigeradas y estabilizadas a 5 °C durante 18 horas. El congelamiento del semen se hizo en pajillas usando vapores de nitrógeno por 4 minutos (-120 °C) y luego sumergidas en nitrógeno líquido. No hubo diferencias estadísticas entre las medias de los tratamientos en todas las características del semen refrigerado. Los resultados pos-descongelación demuestran mejoras con el uso de colesterol en la criopreservación de semen de carnero (p<0.5), obteniendo una motilidad de 65.3, 68.7 y 75.37%, vitalidad de 56.6, 60.7 y 66.2% e integridad de membrana de 50.5, 56.4 y 63.7%, para T1, T2 y T3, respectivamente. No hubo diferencia estadística entre tratamientos con respecto a las anormalidades espermáticas.
Tax Payment Trends in Lithuania in 2008–2009
Authors: Anciūtė Aurelija 
Published: February 2020

The article discusses the most important changes in the Lithuanian tax system, which took ef­fect on 1 January 2009. The main focus is on tax pay­ment trends, i.e. what are the patterns of tax revenue stream determined by the legal basis, how the reve­nue stream is influenced by legislative changes, what is the relationship between the country’s economic situation and the main sources of national budget revenue (value added, individual and company income taxes, excise duties).
Changes in the tax system can be divided into several categories: changes in tax rates, abolition of tax exemptions, changes in tax calculation, declara­tion and payment procedures. All of these changes were a challenge to both taxpayers and tax adminis­trators due to an extremely short period between amendments to legislation and the actual moment when they came into force. It should be noted, how­ever, that, although the changes in the tax system provided additional income to the national budget, the contracting economy forced the national govern­ment to reduce the expectations related to the tax revenue stream.
The article also contains a few alternative views on the growth in the black economy, which is often said to be one of the consequences of tax system changes. Moreover, the so-called “Phoenix” syn­drome is discussed.
Economic Preconditions and Consequences of Contraband
Authors: Rimkus Vladas 
Published: February 2020

The phenomenon of perpetually existing con­traband draws attention of both the public and au­thorities. This is part of black economy, while black economy itself is a phenomenon that is neither new nor characteristic of a certain economic system. The nature of black economy is destructive as its existence
contradicts to public order and interests. Black econo­my avoids state taxes; therefore, the State – in order to collect funds required for national needs – is forced to increase taxes imposed on those who do pay them. Hence, since some avoid paying taxes, while others assume a heavier tax burden, this results in unequal economic conditions for legal and illegal business and distorts conditions for fair competition.
The theoretical study of the problem of contra­band is linked to the problem of tax evasion; it reveals stimuli for making a decision not to pay taxes. The decision of each individual to pay or not to pay taxes determines the scope of tax evasion. Adopting a deci­sion not to pay taxes, one faces uncertainty; any indi­vidual knows that tax evasion is illegal and subject to punishment in case this comes to light. Therefore, the economics of crime gives initial knowledge about the process of making such decisions.
The major part of contraband is comprised of goods subject to excise duties – alcohol, tobacco, and fuel. One of the factors influencing contraband is great difference in prices in Lithuania and neighbour­ing countries from which contraband comes. For ex­ample, contraband cigarettes on the domestic market are approximately three times cheaper than those sold legally. The largest part of these contraband goods comes from neighbouring states – the Russian Federation and Belarus.
The main negative consequences of contra­band are as follows: a relative reduction in annual government revenue; a general deterioration in eco­nomic subordination, which reduces the ability of the government to adopt rational solutions and predict their consequences; insufficient accuracy of provision of social assistance since even those who earn large income from illegal activity may receive it; natural and legal persons tend not to observe existing rules, and the failure to observe the rules may become a norm.

Published: February 2020

El objetivo de la presente investigación es analizar la relación entre depresión y calidad de vida en pacientes con enfermedades crónicas de un hospital de Nivel I de Lima Este. Su diseño es no-experimental, de corte transversal y de tipo correlacional. Para este trabajo se utilizó el Cuestionario de Estado de Salud SF36, que contiene ocho dimensiones, y la Escala de Depresión de Hamilton. La muestra estuvo conformada por 61 pacientes con enfermedades crónicas, de ambos sexos, y con edades entre 20 y 80 años. Los resultados indican una relación inversa altamente significativa entre depresión y las ocho dimensiones de calidad de vida, las cuales comprenden: función física (rho= -.331; p<0.01), rol físico (rho= -.407; p<0.01), dolor corporal (rho= -.448; p<0.01), salud general (rho= -.467; p<0.01), rol emocional (rho= -.518; p<0.01), función social (rho= -.537; p<0.01), vitalidad (rho= -.637; p<0.01) y salud mental (rho= -.566; p<0.01). En consecuencia, se confirma que: a mayor nivel de depresión, menor será la calidad de vida en los pacientes con enfermedades crónicas de un hospital de Nivel 1 de Lima Este.
