Ex-situ conservation of the native orchid Coelogyne rochusseni de Vriese from the Bukit Rimbang and Bukit Baling Wildlife Reserve Areas
Authors: Heriansyah Pebra , Marlina Gusti 
Published: July 2021

The native orchid Coelogyne rochussenii de Vriese is under threat of extinction, so conservation measures need to be taken. In-situ conservation is constrained by time, resources and costs, and the appropriate conservation must be ex-situ. Therefore, This study aims to determine the most effective method for ex-situ conservation, especially basal medium and activated charcoal, in order to determine the fastest germination. The method used in this research was a factorial completely randomized design, consisting of four different basal medium treatments, Knudson C, Vacin and Went, Murashige and Skoog, and Hyponex + Vitamin medium. This treatment was combined with the application of activated charcoal at 4 different levels, with concentrations of 0.1,2.3 g/L-1, the parameters observed were germination day (day), germination percentage (%), and percentage of contamination (%). The results of this study concluded that the conservation of the Native orchid Coelogyne Rochussenii de Vriese using various growing mediums and activated charcoal had a significant effect on the growth of the embryo culture native orchid. Hyponex + Vitamin medium with 3 g/L-1 is able to accelerate germination days to 29.33 days, increase germination percentage to 92.06%, and reduce contamination to 0%.

Authors: Febrianingrum Lasmi , Alim Wahab Syakhirul 
Published: July 2021

This study aims to describe the perception of English teachers about the use of platforms in engaging students during online learning. The participants of this study consist of junior and senior high school teachers in some schools in Madura. Their perceptions were investigated in terms of three aspects: effects of using this learning platform on their perceived motivation, the perceived usefulness, and the perceived ease of use of platforms. The study was conducted in the descriptive method. The data were collected by using a questionnaire and self-structured online interviews. The findings indicated that the teachers perceived that google classroom as the most used LMS and WhatsApp as the most preferred social media since both are user friendly and easy to use. Furthermore, Microsoft PowerPoint or Word and YouTube are the most preferred platform since they are motivating, useful and engaging during English online learning. It was found out that the English teachers are satisfied with the features of the use of these outstanding platforms in their online learning since they provide suitable features for their materials. Moreover, it was found that some teachers choose those platforms since they are more familiar for them to use. Besides, they had been introduced, acquired knowledge and practices on how to use the platform for supporting the learning process. Consequently, it should be training for the teacher about other outstanding learning platforms to be acknowledged and employed in their teaching and learning process.

Published: July 2021

Abstract

OBJECTIVE
To identify differential microRNA (miRNA) expression in dogs with splenic hemangiosarcoma, splenic hematoma, and histologically normal spleens.

ANIMALS
Dogs with splenic hemangiosarcoma (n = 10), splenic hematoma (n = 5), and histologically normal spleens (n = 5).

PROCEDURES
Splenic tissue and serum samples were collected from dogs with splenic masses (ie, hemangiosarcoma or hematoma samples) and healthy control dogs (ie, control samples), and total RNA was extracted. Reverse transcription quantitative real-time PCR was performed with 28 miRNAs associated with hemangiosarcoma, angiosarcoma, or associated genes. Differential expression analysis was performed.

RESULTS
Control tissue and serum samples had similar miRNA expression patterns, and hemangiosarcoma tissue and serum samples did not. Hemangiosarcoma serum samples had higher expression than hemangiosarcoma tissue for 13 miRNAs and lower expression for 1 miRNA. Control tissue and hemangiosarcoma tissue had varying expressions for 12 miRNAs, with 10 more highly expressed in control samples and 2 more highly expressed in hemangiosarcoma samples. Five miRNAs (miR-214-3p, miR-452, miR-494-3p, miR-497-5p, miR-543) had significantly different expression in serum between dogs with splenic masses (ie, hemangiosarcoma or hematoma) and serum of dogs with histologically normal spleens, with higher expression in the serum of dogs with splenic masses for all 5 miRNAs.

CONCLUSIONS AND CLINICAL RELEVANCE
5 circulating miRNAs were identified that distinguished dogs with splenic hemangiosarcoma or hematoma from those with histologically normal spleens. These 5 miRNAs had higher expression in dogs with splenic masses, indicating upregulation of these circulating miRNAs occurs in these splenic disease states. These miRNAs may be useful as a noninvasive screening tool that uses serum to identify dogs with splenic masses.
Los postulados constitucionales respecto al cerramiento del espacio público en Colombia. una mirada desde la jurisprudencia de la Corte Constitucional y el Consejo de Estado de 1991 a 201
Authors: Vargas Angelica , Chávez Ernesto 
Published: July 2021

El presente artículo surge con el objetivo de estudiar y comprender los postulados constitucionales respecto al espacio público, creados de conformidad con la Constitución Política Colombiana de 1991, normativa que impulsó ambiciosas políticas encaminadas a proteger el espacio público en el país, lo que ha promovido que el Estado colombiano deba tomar una posición protectora de este derecho, el cual debe ser comprendido como un derecho colectivo que recoge aspectos políticos, sociales y culturales enmarcados en el fortalecimiento de una nueva cultura ciudadana. Teniendo en cuenta que el Espacio Público es objeto de regulación jurídica en virtud de la acción del Estado en sus diversos niveles, desde las definiciones y prescripciones de carácter legal, hasta las disposiciones, reglamentos y ordenes administrativas. Lo que desemboco en generar cuestionamientos desde las altas esferas de la Corte Constitucional y el Consejo de Estado, instancias jurídicas que decantaron protecciones constitucionales enfocadas en diversos ámbitos, conllevando en todo caso a crear un choque de trenes respecto de la protección estatal frente a la protección del espacio público, causando en todo fin que el Estado deberá proteger los derechos protegidos en la carta magna en la mayor medida posible.

Clinical Characteristics, Cardiac Magnetic Resonance Features, and Outcomes of Patients with Dilated Cardiomyopathy – An Experience from a South Asian Country
Authors: Shams Pirbhat , Sultan Fateh Ali Tipoo 
Published: July 2021

Objectives:
The objectives of the study were to evaluate the clinical presentation, cardiac magnetic resonance (CMR) features, and outcomes of patients with dilated cardiomyopathy (DCM).

Material and Methods:
A retrospective study was conducted at a tertiary care center of Pakistan. All patients who underwent CMR for further evaluation of DCM during the period of 2011–2019 and in whom CMR confirmed the diagnosis of DCM, were included in the study. Patients were followed up in the year 2020 for all-cause mortality and cardiovascular hospitalizations.

Results:
A total of 75 patients were included in the study. The mean age was 38.7 ± 13 with the majority (n = 57, 76%) being male. Dyspnea was the most common presenting symptom (n = 68, 90.7%). The mean left ventricle ejection fraction (LVEF) by CMR was 29.3 ± 12 and mean left ventricle stroke volume (LVSV) was 66.5 ± 31. Late gadolinium enhanced (LGE) was present in 28 (37.3%) patients. Follow-up was available in 61 patients with the mean follow-up duration of 39.7 ± 27 months. Most patients (40, 65.6%) experienced all-cause major adverse cardiovascular events (MACE) during the follow-up and mortality was observed in 10 (16.4%) patients. LVSV by CMR (P = 0.03), LVEF by CMR (P = 0.02), and presence of pericardial effusion (PE) (P = 0.01) were significantly associated with all-cause MACE. On multiregression analysis, SV by CMR was associated with all cause MACE (P = 0.048). The presence of LGE was associated with higher mortality (P = 0.03).

Conclusion:
LVSV, LVEF by CMR, and PE were significantly associated with all-cause MACE. LGE was associated with higher mortality. Our cohort had a relatively younger age of presentation and diagnosis, and a greater mortality on follow-up, when compared with other regions of the world.
Diffuse Infiltrative Non-mass-like Brain Parenchymal Lesions on MRI: Differentiating Lymphomatosis Cerebri from its Mimics
Authors: Patra Anurima , Jasper Anitha , Vanjare Harshad , Chacko Geetha , Susheel Sherin , Sivadasan Ajith , Hephzibah Julie , Mannam Pavithra 
Published: July 2021

Objectives:
Diffuse infiltrative “non-mass-like” parenchymal lesions on MRI brain are a known presentation of an aggressive condition called lymphomatosis cerebri (LC) but are often misdiagnosed due to its non-specific clinical and imaging findings. We aim to identify clues to differentiate lymphomatosis from its less aggressive mimics based on imaging features.

Material and Methods:
MRI brain studies showing diffuse infiltrative “non-mass-like” parenchymal lesions between January 2013 and March 2020 were retrospectively identified and read for lesion location, signal characteristics, and enhancement pattern by two radiologists. Additional findings on MRI spine and whole-body fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) were recorded wherever available. The clinical diagnosis, patient demographics, symptoms, laboratory and histopathology results, treatment details, and follow-up details were also noted.

Results:
Of the 67 patients, 28 (41.7%) were diagnosed with lymphomatosis. The remaining 39 (13.4%) patients were classified as non-lymphomas (infective, vasculitis, and inflammatory conditions). Diffusion restriction on MRI (20/67, P = 0.007) and increased regional activity on FDG PET-CT (12/31, P = 0.017) were the two imaging parameters found to significantly favor lymphomatosis over other conditions, whereas the presence of microhemorrhages on susceptibility-weighted imaging was significantly associated with vasculitis (P = 0.002). Rapid clinical or imaging deterioration on a short trial of steroids (P = 0.00) was the only relevant clinical factor to raise an early alarm of lymphomatosis. Positive serological markers and non-central nervous system systemic diseases were associated with non-lymphomatous diseases.

Conclusion:
LC and its less aggressive mimics can be differentiated on diffusion-weighted imaging-MRI and PET-CT when read in conjunction with rapid progression of clinical features, serological workup, and systemic evaluation.

Authors: Баландин Сергей Витальевич 
Published: July 2021

В статье оценивается флора хребта Басеги по ряду экологических факторов: водному, световому режимам, богатству почв элементами минерального питания. По водному режиму наблюдается преобладание мезофитов - 53,4%. По световому режиму приблизительно равное соотношение светолюбивых (50,1%) и теневыносливых (47,5%) видов. По богатству почв элементами минерального питания явно преобладают мезотрофы - 72,5%. Территорию можно охарактеризовать, как с преобладанием умеренно увлажненных местообитаний, равным соотношением сообществ без выраженного затенения и выраженным затенением нижних ярусов, и умеренным содержанием в почвах элементов минерального питания. Аналогичная ситуация прослеживается и по высотным поясам, кроме горно-лесного пояса, где по световому режиму преобладают теневыносливые виды.
The article assesses the flora of the Basegi Ridge by a number of environmental factors: water, light conditions, and the richness of soil elements with mineral nutrition. The water regime is dominated by mesophytes - 53,4%. According to the light regime, the ratio of light-loving (50,1%) and shade-tolerant (47,5%) species is approximately equal. Soils rich with mineral elements are clearly dominated by mesotrophs - 72,5%. The territory can be characterized as having a predominance of moderately moist habitats, an equal ratio of communities without pronounced shading and pronounced shading of the lower tiers, and a moderate content of mineral nutrition elements in the soils. A similar situation is observed in high-rise belt, except for the mountain-forest belt, where shade-tolerant species predominate in the light regime
