Abstract:
Background: The aim of the study was to evaluate radiographic features of systemic sclerosis-associated interstitial lung disease. Patients and methods: 116 patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) from 2010 to 2019 comprised our retrospective study. All patients were subject to high resolution computed tomography (HRCT). ILD patterns were classified into 7 patterns as IIPs and analyzed with pathology. We chose two staging method and two semi-quantitative score methods to evaluate the HRCT performance and analyzed with pulmonary function tests. Results: Ground-glass opacities were the most common presentation on HRCT, followed by interlobular septal thickening, reticular opacities, intralobular interstitial thickening; honeycombing, traction bronchiectasis and nodules can also be observed. The most common pattern of SSc-ILD was nonspecific interstitial pneumonia (NSIP), secondly was UIP. There was no difference in ILD pattern between HRCT and pathology, and revealed a high congruence. The four HRCT evaluating methods presented in this study all had significant relationships with PETs. Conclusion: The most common pattern of SSc-ILD was nonspecific interstitial pneumonia (NSIP). The ILD patterns of HRCT coincide very well with histology, and will replace pathology as the gold standard for diagnosis and evaluation of SSc-ILD.

Abstract:
Like microscopes and thermal cyclers, computers are routinely used in many laboratories. Bioinformatics is a recent scientific discipline that has undergone strong and rapid progression and evolution (Ouzounis, 2012). The use of bioinformatics analyses in biological studies in fields as diverse as metagenomics (Hurwitz et al., 2014) and infectious diseases (Gire et al., 2014) is now accepted and viewed as normal. As mentioned in PLoS computational biology by Hogeweg (2011), the first time the term “bioinformatics” was used was in 1970 in a Dutch article. At the time, bioinformatics referred to “the study of informatic processes in biotic systems.” Since then, bioinformatics has gradually carved out a place for itself in the scientific community with, for example, the creation in 1985 of CABIOS (Computer Applications in the Biosciences), which is now known as Bioinformatics (Oxford, England). However, the main impulse for the emergence of bioinformatics came from the completion of the human genome project at beginning of the new century. However, it also gave rise to a fundamental question. What exactly is bioinformatics? Because of the importance of bioinformatics, this neologism was quickly added to the Oxford English Dictionary (OED), and discussions about the definition of bioinformatics also heated up (Luscombe et al., 2001). According to the OED, bioinformatics is “the branch of science concerned with information and information flow in biological systems, especially the use of computational methods in genetics and genomics.” While this definition is very broad and can be unclear and somewhat open to interpretation, the definition of bioinformatician is even less clear: “An expert in or practitioner of bioinformatics.” Because bioinformatics is carving out an increasingly important place in research and because we have to help students to understand their future role in research, a simple but complex question came to mind: Who qualifies to be a bioinformatician? To attempt to answer this question, let us start with a simple observation. In the past few years, there has been an explosion in bioinformatics tools, some are free and are under a public license (Vincent and Charette, 2014) while others are proprietary and are sometimes distributed by companies (Smith, 2014). In the early years of bioinformatics, the tools were mainly command lines and were less accessible to neophytes. The people developing and using these tools were mainly considered bioinformaticians, that is, people with sufficient skills in informatics and biology to use the tools and analyze the results. However, in fact, bioinformaticians designed these tools for themselves not for biologists, which caused a certain degree of discontent in the scientific community (Kumar and Dudley, 2007). However, powerful and much simpler tools are now available with an easy-to-understand interface, including NCBI Blast (Johnson et al., 2008), Unipro UGENE (Okonechnikov et al., 2012), the web server CONTIGuator (Galardini et al., 2011), the genome viewer Artemis (Rutherford et al., 2000), and many others. These tools have provided biologists with user-friendly bioinformatics tools. Since many biologists now conduct sophisticated bioinformatics analyses, can they be called bioinformaticians? This is not an easy question to answer, in part because of the broad definition of bioinformatics. At the very beginning of his book Perl Programming for Biologists (Jamison, 2003), Curtis D. Jamison differentiates between two conceptual aspects of bioinformatics: computational biology and analytical bioinformatics. Computational biology uses algorithms to mathematically (statistically) analyze biological problems and tries to build a model to infer solutions using a computational approach. On the other hand, analytical bioinformatics uses bioinformatics tools to conduct analyses in a biological context. Consequently, we can reformulate the question posed above in a more accurate way. Can people working in the fields of computational biology or analytical bioinformatics be considered bioinformaticians? We are aware that gray zones exist and will likely always exist, even as the field of bioinformatics evolves. However, it will be easier to provide an answer to our question. As for the definition provided by OED, we propose that bioinformaticians are experts in the field of bioinformatics. They may be users, but this is not enough to consider them as bioinformaticians (i.e., an expert). Bioinformaticians are scientists who develop and conduct research based on a bioinformatics approach, they do not just use the tools to better understand a biological problem. It is a little like saying that driving your car to work does not make you a mechanic. A bioinformatician is a scientist who understands the underlying “mechanics” of bioinformatics or, more realistically, an aspect of bioinformatics (genomics, protein structure predictions, phylogenetic models, etc.). In a more conceptual framework, bioinformaticians can perhaps be seen as the “missing link” required for improving multidisciplinary research. Since they can bridge biological sciences, informatics, and mathematics, fully fledged bioinformaticians can be valuable assets for multidisciplinary studies. For example, more and more bioinformaticians are becoming involved in major multidisciplinary studies such as those on cancer (Hanauer et al., 2007; Valencia and Hidalgo, 2012) as well as in whole-exome sequencing (WES), which is an increasingly important method used in medical studies (Sanders et al., 2012; Wang et al., 2013; Zhu et al., 2015). In fact, we are probably able to separate the bioinformaticians in two categories which are not mutually exclusives: (1) the developers who are working directly on algorithms (conception), the development aspects and the maintenance of tools and (2) the curators who architecturally design and maintain data resources and provide an integration of the curated data. There are great bioinformaticians for example at NCBI (http://www.ncbi.nlm.nih.gov), EMBL (http://www.ebi.ac.uk), and The Comprehensive Antibiotic Resistance Database (CARD) (McArthur et al., 2013), who maintain and curate databases and others who are developing and maintaining the different tools. These databases and others need bioinformaticians who are skilled in both informatics and biology and who can provide a link between the various tools and the data and who can validate the entries in order to maintain a high level of scientific rigor. Consequently, in our opinion a biologist who only uses bioinformatics tools to perform analyses but does not contribute at the conception of such tools or not fits in the curator definition provided above is not a bioinformatician. She or he may use the tools proficiently, but as a user not as a bioinformatician. In fact, a strict user of bioinformatics tools could be an expert in another field, for example a genomicist can uses bioinformatics tools, without being a bioinformatician. But, what about the flip side of the coin: a bioinformatician who focuses on informatics problems? We believe that it is easier for a bioinformatician to become an informatician. However, the term bioinformatics encompasses two concepts: “bio,” which refers to biological sciences, and “informatics,” which refers to computational sciences. Just like a biologist is not a bioinformatician, an informatician is not a bioinformatician. It is important to keep in mind that bioinformatics has to be applied in a biological context. For example, maintaining a biological web server (without a curating aspect) is not a bioinformatics task. Informaticians with networking and programming language (SQL, HTML, Python) skills can do the job. It could be a part of a bioinformatician's job, but it should not be the only part of his or her job, otherwise the bioinformatician becomes an informatician. As bioinformatics gains in importance, it is crucial that the concept of bioinformatician be clearly defined. A clear definition will help universities to adapt their bioinformatics programs to their true needs and to produce real bioinformaticians with the proper skills. This will also help human resources departments to improve the accuracy of job descriptions and avoid the many knotty administrative issues involved in defining tasks, categorizing employees for union purposes and perhaps, most importantly, recognizing and certifying bioinformaticians. Like virus taxonomy, a good definition of a bioinformatician should not be based on a single concept but should be polythetic, this is, real bioinformaticians share a number of common characteristics, but none of which is essential. Many university departments, including ours, now give mandatory bioinformatics courses to students enrolled in biology, biochemistry, and microbiology programs, among others. This is essential in a context where these students will be called on to use bioinformatics tools and the results provided by them during their careers. However, it is also important for students to realize that a 45-h bioinformatics course will not make them experts in the field or qualify them as bioinformaticians. Much more training will be needed to reach that goal. The goal of this paper is thus to contribute to the discussion of how best to define people working in a constantly evolving field like bioinformatics, which in turn is part of the larger discipline of computational science. As for bioinformatics, other sciences such as physics, mathematics, and chemistry will probably also have to evolve and adapt at this emerging and important field.

Abstract:
Area and production of raw jute has decreased, though there is a high demand of raw jute in the country. In order to assess production constraints, a survey was carried out in 2005/06 in Jhapa, Morang and Sunsari districts. The study revealed that unstable or low price of raw jute, unavailability of quality jute seed, limited irrigation water at sowing period, diseases complex (wilt), labor shortage during peak season, weed problem, lack of retting water/retting pond were the main constraints in jute production and processing. The study indicates that the maximum production cost has involved in fiber extraction (16.9%) and weeding (16.33%). Jute productivity ranged from 1788 to 2260 kg per hectare. JRO-524 variety of jute has been widely grown across the region due to its wider adaptability, high yield potential and quality fiber. Jute area has been replaced by sugarcane due to its high yield potential and high profit margin. It is observed that the cost of production of jute is high as compared to other crops in the season. Average cost of production of fiber was estimated to be Rs.1563/quintal. For the promotion of jute cultivation in the eastern Terai, it would be better to provide subsidies on seeds and fertilizer to jute growers as practiced in neighboring countries thereby profit margin becomes high and will encourage growers in producing more raw jute within the country for the fulfillment of raw jute requirement of local jute industries. Cost effective technologies have to be developed in jute production and processing aspects for lowering the production cost and increasing the profit margin. Popular genotypes JRO- 524 which was widely adopted needs to be recommended officially for the general cultivation in this region. Being an eco-friendly crop, promotion is required to adapt climate change effect and maintaining the soil properties in jute growing areas.
