ABSTRACT: The growth of Pteridophyta in the Permai Gisting Forest Area, Gisting Sub-District Tanggamus Regency was strongly influenced by biotic and abiotic factors. Biotic factors include all the life of living things on earth both individuals, populations and communities which include a large number of Pteridophyta hosts, while abiotic factors include all non-living factors of an environmental condition such as sunlight, temperature, water, and soil, height. These abiotic factors not only provide important energy and material, but also had a role in determining plants and animals that which are able to be in a certain place according to their habitat. The method used in this study is a qualitative study. This article was reviewed by citing references from various sources including journals, books, Gisting Permai archive documents, and the internet. The data collection was obtained by using as many references as possible related to biotic and abiotic factors for fern growth.

Published: March 2021

Abstract
The article presented describes a new design of measuring chains in laboratory test equipment, which are used for testing the hydrostatic transducers and hydraulic fluids. Laboratory test equipment allows simultaneous observation of parameters of hydrostatic transducers and hydraulic fluids by simulating the operating conditions under laboratory conditions, what can significantly reduce the testing time and economic costs. The new design functionality was verified via measurement of the basic parameters of hydrostatic transducers and changing the load of hydraulic fluids. Based on the results measured, the flow efficiency of tested hydrostatic transducer UD-25R was calculated and compared with the transducer parameters specified by the manufacturer using different types of operating hydraulic fluids. Verification measurements of the unloaded hydrostatic transducer were performed at various rotation speeds: Q
250 = 5.694 dm3·rpm at speed of n
1 = 250 rpm; Q
500 = 12.286 dm3·rpm at speed of n
2 = 500 rpm; Q
750 = 18.747 dm3·rpm at speed of n
3 = 750 rpm. Based on the hydrostatic transducer flow rate, the UD-25R transducer flow efficiency was determined: at n
1 = 250 rpm, the flow efficiency was η250 = 0.8946; at n
2 = 500 rpm, the efficiency was η500 = 0.9651; at n
3 = 750 rpm, the flow efficiency was η750 = 0.9812.

Published: March 2021

Tuberculosis is an infectious disease which has affected millions of people around the world. Ten million new TB cases were identified globally in 2018, with an estimated 1.2 million deaths. Lung function impairment often occurs due to the destruction of the lung parenchyma. This causes ventilatory abnormalities, often of obstructive type. Radiological lesions are also a common consequence of pulmonary tuberculosis. This study aims to analyse the various clinical features and assess the spirometric and radiological findings in post TB patients. This is a prospective observational study. All patients visiting the Chest Medicine OPD of Saveetha Medical College and Hospital who had a history of treated pulmonary tuberculosis and were above 18 years of age were included in this study. Patients who had no signs of active Tuberculosis underwent spirometry, and a chest x-ray was taken. Clinical presentation, spirometric parameters and radiological lesion were analysed. Among the 76 patients included in this study, 73.7% were male with most patients aged between 51 to 60 years. 64.5% of the study population were smokers. Dyspnoea (94.73%) was found to be the most common presenting complaint. Obstructive pattern (49%) was found to be the most common type of spirometric pattern with 68.42% having small airway disease. Based on the Wilcox classification, Degree II (47.37%) was the most common extent of the radiological lesion. It was found that there is a statistically significant difference between smokers and non-smokers in post-bronchodilator FEV1 (p=0.037) and FEF25-75 values (p=0.010). This study reveals the presence of post tuberculosis lung impairment in the population with varying presentations and severity. Hence, further studies and interventions are required to improve the quality of life of post tuberculosis patients.

Native American and land-grant collection praxis since NAGPRA
Authors: Pappas Alisa M. , Buchanan Sarah A. 
Published: March 2021

Since the granting of Native American materials – excavated in archaeological projects sponsored by federal and state governments across the United States in the 20th century – to public repositories, museum professionals have sought to manage such collections with care. At the University of Missouri, students responding to the local mandate of NAGPRA advocated a public investigation into the issue of Native American collections repatriation in the early 1990s. Their activism in part transformed campus praxis in three ways, effecting ethical shared decision-making, appropriate public access, and policy-level leadership. This paper examines the primary sources generated by students, faculty, and local and national journalists to broadly comprehend how community members continue to address Native collections management and access in a public land-grant university setting.

BACKGROUND: There are few studies to compare antibody response against anti-spike (S) and anti- nucleoprotein (N) SARS-CoV-2. OBJECTIVE: The aim of this study was to evaluate the IgG antibody production against S and N antigens of the virus and their correlation with the time and severity of the disease. METHODS: The IgG antibodies against S and N antigens of SARS-CoV-2 in serum specimens of 72 symptomatic patients who tested real-time reverse transcription polymerase chain reaction positive for SARS-CoV-2 were detected using the ELISA technique. Different antibody response was compared and the correlation with the time from disease onset and the severity was evaluated. RESULTS: Forty-eight of 72 (67%) patients tested positive for anti-SARS-CoV-2 antibodies, while 24 (33%) did not have detectable antibodies. Comparison of antibody levels for N and S antibodies showed that they correlate with each other well (r= 0.81; P< 0.001). However, sensitivity of anti-S SARS-CoV-2 IgG and anti-N SARS-CoV-2 IgG was 30% and 60%, during the first 7 days after symptom onset (r= 0.53; P= 0.111), but increased to 73% and 68% at more than 1-week post symptom onset (r= 0.89, P= 0.111), respectively. Cases with positive IgG response showed a decreased CD8+ T cells percentage compared to the negative IgG groups (26 ± 14 vs. 58 ± 32, p= 0.066 in anti-N IgG group and 28 ± 15 vs. 60 ± 45, p= 0.004 in anti-S IgG group, respectively). CONCLUSION: Nearly one-third of the confirmed COVID-19 patients had negative serology results. Lower percent positivity at early time points after symptom onset (less than 1 week) was seen using anti-S SARS-COV-2 IgG kit compare to the anti-N SARS-CoV-2 IgG; therefore, clinicians should interpret negative serology results of especially anti-S SARS-CoV-2 IgG with caution.
Targeted Therapies for Metabolic Myopathies Related to Glycogen Storage and Lipid Metabolism: a Systematic Review and Steps Towards a ‘Treatabolome’

Published: March 2021

Background: Metabolic myopathies are a heterogenous group of muscle diseases typically characterized by exercise intolerance, myalgia and progressive muscle weakness. Effective treatments for some of these diseases are available, but while our understanding of the pathogenesis of metabolic myopathies related to glycogen storage, lipid metabolism and β-oxidation is well established, evidence linking treatments with the precise causative genetic defect is lacking. Objective: The objective of this study was to collate all published evidence on pharmacological therapies for the aforementioned metabolic myopathies and link this to the genetic mutation in a format amenable to databasing for further computational use in line with the principles of the “treatabolome” project. Methods: A systematic literature review was conducted to retrieve all levels of evidence examining the therapeutic efficacy of pharmacological treatments on metabolic myopathies related to glycogen storage and lipid metabolism. A key inclusion criterion was the availability of the genetic variant of the treated patients in order to link treatment outcome with the genetic defect. Results: Of the 1,085 articles initially identified, 268 full-text articles were assessed for eligibility, of which 87 were carried over into the final data extraction. The most studied metabolic myopathies were Pompe disease (45 articles), multiple acyl-CoA dehydrogenase deficiency related to mutations in the ETFDH gene (15 articles) and systemic primary carnitine deficiency (8 articles). The most studied therapeutic management strategies for these diseases were enzyme replacement therapy, riboflavin, and carnitine supplementation, respectively. Conclusions: This systematic review provides evidence for treatments of metabolic myopathies linked with the genetic defect in a computationally accessible format suitable for databasing in the treatabolome system, which will enable clinicians to acquire evidence on appropriate therapeutic options for their patient at the time of diagnosis.

BACKGROUND: There is a paucity of knowledge regarding neuroendocrine neoplasms (NEN) in patients with HIV infection. OBJECTIVE: To explore the incidence, characteristics and treatment outcomes of NEN in HIV-positive individuals. METHODS: This is a single-center, descriptive cohort study. Patients with HIV and biopsy-confirmed NEN were identified from our data registry. Data were collected retrospectively from medical records. Progression-free and overall survival (OS) were estimated using the Kaplan-Meier method. RESULTS: Nineteen HIV-positive patients with neuroendocrine tumors (NET) ( n = 14), neuroendocrine carcinomas (NEC) ( n = 2) or Merkel cell carcinoma (MCC) ( n = 3) were included (median age at NEN diagnosis, 53 years). In 15 (79%) patients, HIV diagnosis preceded NEN diagnosis by a median of 11 years and 14 were receiving antiretroviral therapy (ART). Of those with data available, 75% had a viral load < 50 copies/ml and mean CD4 771 cells/mm3. The median OS in the NEC/MCC cohort was 8 months (range 5–29). The median OS in the NET cohort was not reached but based on the 25th centile, 75% of patients are expected to survive for at least 57 months. Treatment outcomes will be described. CONCLUSIONS: Within the limits of a small descriptive cohort study, we found no evidence in the era of ART that patients with HIV and NEN are diagnosed at a younger age, nor have a poorer prognosis compared with the wider NEN population. Thus, they should receive maximal NEN therapies to support best outcomes.

La creación de valor en las empresas es un concepto relativamente novedoso en el entorno económico y microempresarial del país, la mayoría de pymes utilizan indicadores tradicionales para medir el grado de liquidez, eficiencia, rentabilidad y endeudamiento; sin embargo los mismos presentan grandes limitaciones ante nuevos escenarios relacionados con posibles fusiones, integraciones estratégicas, compra venta, entre otros; incluso ante la posibilidad de ampliación de capital proveniente de fuentes internas y externas. La presente investigación tiene como finalidad establecer el grado de relación de que existe entre la Evaluación financiera con la generación de Valor Económico Agregado (EVA); tomando como caso de estudio la fábrica de embutidos la Ibérica de la ciudad de Riobamba. Se parte de la premisa de que este indicador financiero puede calcularse para todo tipo de empresas, y su característica es que integra todos los costos y gastos incurridos en las empresas durante un periodo, incluido el costos de capital que generalmente no es considerado en la evaluación financiera tradicional al momento de establecer la situación económica y financiera de la empresa. El tópico es de relevancia actual, e invita a la aplicación por parte de los empresarios y administradores financieros de nuevos enfoques en la toma de decisiones. La investigación es de carácter descriptiva y provino de la organización, análisis e interpretación cuantitativa de los estados financieros y de la recopilación de información cualitativa proporcionada por el personal administrativo y financiero de la empresa. Los resultados demuestran una correlación altamente positiva entre el EVA y la Gestión Financiera. Se concluye en la necesidad de aplicación de estrategias financieras que permitan mayor creación de valor agregado o riqueza para sus propietarios de forma sustentable en el corto y largo plazo.
