Abstract. Yusuf R, Tang UM, Karnila R, Fuadi I, Pato U. 2020. Ecological sustainability of rice farms in Siak District, Riau, Indonesia. Biodiversitas 21: 3797-3804. The research was conducted in Siak District, Riau Province, Indonesia from January to July 2018 in the four subdistricts of rice production centers. The purpose of this study was to identify the ecological conditions of rice farming, analyze the index and ecological sustainability status of lowland rice farming, and analyze the role of each ecological attribute that will have sensitivity to the management of wetland rice in the development of rice farming in the Siak District in the near future. There were 203 sample farmers selected by purposive sampling. Data collection was done by interview and field observation. The sustainability was analyzed using the Rap-Rice method with Multidimensional Scaling (MDS). The results of the Rap-Rice analysis of eight ecological attributes were analyzed; five attributes provided high sensitivity for Sungai Mandau, and three attributes provided high sensitivity for the subdistricts of Bunga Raya, Sabak Auh, and Sungai Apit. Attributes that provided high sensitivity for all subdistricts were attributes of land suitability with land use plans and land conversion rates. The average attributes of ownership of the farm area provided high sensitivity for only three subdistricts (Sabak Auh, Sungai Apit, Sungai Mandau). Based on ecological conditions, analysis of wetland rice farming in Siak District showed a sustainable category for Bunga Raya (56.10%), Sabak Auh (52.80%), and Sungai Mandau (54.90%) and less sustainability for Sungai Apit (48.80%).

Abstract Despite the tremendous progress made in recent years in assembling the human genome, tandemly repeated DNA elements remain poorly characterized. These sequences account for the vast majority of methylated sites in the human genome and their methylated state is necessary for this repetitive DNA to function properly and to maintain genome integrity. Furthermore, recent advances highlight the emerging role of these sequences in regulating the functions of the human genome and its variability during evolution, among individuals, or in disease susceptibility. In addition, a number of inherited rare diseases are directly linked to the alteration of some of these repetitive DNA sequences, either through changes in the organization or size of the tandem repeat arrays or through mutations in genes encoding chromatin modifiers involved in the epigenetic regulation of these elements. Although largely overlooked so far in the functional annotation of the human genome, satellite elements play key roles in its architectural and topological organization. This includes functions as boundary elements delimitating functional domains or assembly of repressive nuclear compartments, with local or distal impact on gene expression. Thus, the consideration of satellite repeats organization and their associated epigenetic landmarks, including DNA methylation (DNAme), will become unavoidable in the near future to fully decipher human phenotypes and associated diseases.

The treatment of ulcerative colitis (UC) has changed over the last decade. It is extremely important to optimize the therapies which are available nowadays and commonly used in daily clinical practice, as well as to stimulate the search for more powerful drugs for the induction and maintenance of sustained and durable remission, thus preventing further complications. Therefore, it is mandatory to identify the patients' prognostic variables associated with an aggressive clinical course and to test the most potent therapies accordingly.To date, the conventional therapeutic approach based on corticosteroids, salicylates (sulfasalazine, 5-aminosalicylic acid) or immunosuppressive agents is commonly used as a first step to induce and to maintain remission. However, in recent years, knowledge of new pathogenetic mechanisms of ulcerative colitis have allowed us to find new therapeutic targets leading to the development of new treatments that directly target proinflammatory mediators, such as TNF-alpha, cytokines, membrane migration agents, cellular therapies.The aim of this review is to provide the most significant data regarding the therapeutic role of drugs in UC and to give an overview of biological and experimental drugs that will become available in the near future. In particular, we will analyse the role of these drugs in the treatment of acute flare and maintenance of UC, as well as its importance in mucosal healing and in treating patients at a high risk of relapse.

Potential Role of Cytokines in Children with Acute Appendicitis and Acute Mesenteric Lymphadenitis Although, AAP and AML have different etiological factors, clinical symptoms are very much similar but treatment tactics in both the disease differ a lot. In case of AML, treatment is more conservative and does not require hospitalization while in case of AAP immediate hospitalization and maybe further surgery can be mandatory. With the identification of group of cytokines serum inflammatory mediators IL-8, IL-10, IL-12[p70], IL-17, TNF-a and MCP-1, it is believed early and proper diagnosis of AAP in the near future. Research of cytokines-serum inflammatory mediators has opened new opportunities for an early detection and differentiation of these two diseases in children.

Background: Captopril is the synthetic dipeptide used as an angiotensin converting enzyme inhibitor. Captopril is used to treat hypertension as well as for the treatment of moderate heart failure. Analytical instrumentation and methodology plays an important role in pharmaceutical analysis. Methods: This review presents some important applications of electrochemical modes used for the analysis of captopril. So far captopril has been analyzed by using different bare and modified working electrodes with a variety of modifiers from organic and inorganic materials to various types of nano particles/materials. Results: This paper presents some of the methods which have been published in the last few years i.e. from 2003 to 2016. This review highlights the role of the analytical instrumentation, particularly electrochemical methods in assessing captopril using various working electrodes. Conclusion: A large number of studies on voltammetry noted by means of various bare and modified electrodes. Among all of the published voltammetric methods, DPV, SWV, CV and miscellaneous modes were trendy techniques used to analyze captopril in pharmaceutical formulations as well as biological samples. Electrodes modified with nanomaterials are promising sensing tools as this showed high sensitivity, good accuracy with precision as well as selectivity. In comparison to chromatographic methods, the main advantages of electrochemical methods are its cheaper instrumentation, lower detection limit and minimal or no sample preparation.

I analyse the role of simultaneity in relativistic rotation by building incrementally on its role in simpler scenarios. Historically, rotation has been analysed in 1 + 1 dimensions; but my stance is that a 2 + 1 -dimensional treatment is necessary. This treatment requires a discussion of what constitutes a frame, how coordinate choices differ from frame choices, and how poor coordinates can be misleading. I determine how precisely we are able to define a meaningful time coordinate on a gravity-free rotating Earth, and discuss complications due to gravity on our real Earth. I end with a critique of several statements made in relativistic precision-timing literature, that I maintain contradict the tenets of relativity. Those statements tend to be made in the context of satellite-based navigation; but they are independent of that technology, and hence are not validated by its success. I suggest that if relativistic precision-timing adheres to such analyses, our civilian timing is likely to suffer in the near future as clocks become ever more precise.

Abstract Background Acute bilateral lower limb weakness is a common problem in children which necessitates a rapid method for diagnosis. MRI is a non-invasive imaging technique that produces high-quality images of the internal structure of the brain and spinal cord. Results MRI was very helpful in reaching rapid and prompt diagnosis in children with acute inability to walk. Acute disseminated encephalomyelitis (ADEM), Guillain–Barré syndrome (GBS), and acute transverse myelitis (ATM) were the most common causes in our study. MRI proved to be of high sensitivity in detecting the lesions and reaching the diagnosis in ADEM and GBS; however, there was no significant relation between the lesions’ size, enhancement pattern, and severity of the disease or prognosis, yet in ATM the site of the lesion and number of cord segment affection were significantly related to the severity of the disease and prognosis. Conclusion MRI is a quick tool to reach the diagnosis of children with acute secondary inability to walk, and to eliminate other differential diagnosis which is essential for proper treatment and rapid full recovery. It is highly sensitive in detecting the lesions, their site and size.

Cardiac amyloidosis is a severely underdiagnosed cause of heart failure with preserved ejection fraction. We report a case of highly probable transthyretin (ATTR) cardiac amyloidosis (ATTR-CA) diagnosed through the assistance of non-invasive multimodality imaging. An 81-year-old man presented with worsening dyspnoea, reduced effort tolerance and limb swelling. Examination and bedside investigations demonstrated congestive cardiac failure. On arrival, N-terminal-pro B-type natriuretic peptide was 2400 ng/L, and high-sensitivity troponin T was 78 mmol/L. Echocardiography showed severe left and right ventricular hypertrophy, and a Doppler study revealed diastolic dysfunction. Cardiac magnetic resonance imaging revealed on non-conventional dark blood sequence an abnormal inversion time for nulling myocardium suggestive of infiltrative disease, including amyloidosis. The patient was referred for nuclear-based studies involving technetium-99m pyrophosphate which demonstrated changes highly diagnostic of ATTR-CA. Early diagnosis of ATTR-CA remains paramount due to the increasing availability of disease-modifying therapies. Current guidelines recognise the role of multimodality imaging in confidently recognising the disease without the need for histological evidence in the appropriate context, providing an alternative means of diagnosis.
