Mining is a strategic sector that must be utilized by the government as well as possible. In accordance with the mandate contained in Article 33 of the 1945 Constitution, the government or the state is obliged to serve every citizen and resident to fulfill their basic needs in the context of public services and improving the welfare of the community. One of the public services that get a bad impression in the community is related to licensing services. At the beginning of 2021, there was a case phenomenon that became a polemic of debate among the community, government and environmental health observers. The phenomenon is that it is easy for the government to issue a mining business permit (IUP) decree to PT Tambang Mas Sangihe (TMS) which substantially violates Law Number 27 of 2007 concerning Management of Coastal Areas and Small Islands as well as having a large potential to cause environmental damage because some of the the area that gets the mining permit is a protected forest which is home to several endemic animals and plants that are threatened with extinction. This study uses normative research methods to determine the legal consequences of the policy. The purpose of this study is to provide several points of consideration to the government in terms of re-evaluating the decree. The results of this study indicate that Decree Number 163.K/MB.04/DJB/2021 has legal consequences for re-evaluation because in addition to violating other laws, the decision has the potential to cause damage to the natural environment in the Sangihe Islands.

Konsep “pengembangan” yang digunakan dalam penelitian ini, menggabungkan pendapat Sammeng (2001), Andrew E. Sikula dalam Sedarmayanti (2009) dan Yoeti (2008). Oleh karena itu konsep “pengembangan” dimaknai sebagai proses perubahan sistem yang dilakukan secara sadar dan terencana menuju kondisi yang lebih baik dalam aspek sumber daya manusia, aspek fisik maupun aspek non fisik lainnya. Sedangkan terkait penyelenggaraan wisata halal di Kota Aceh, digunakan dasar peraturan Wali Kota Banda Aceh Nomor 17 tahun 2016 tentang penyelenggaraan wisata halal. Hasil penelitian menemukan bahwa masih terdapat fasilitas yang kurang memadai, kurangnya jumlah pegawai, serta kurangnya pemahaman dan kesadaran masyarakat dalam pengembangan wisata halal di Kota Banda Aceh. Dari tiga dimensi yang diamati, yaitu dimensi pengembangan obyek dan destinasi wisata, dimensi penyediaan prasarana, serta dimensi pengembangan SDM wisata, kesemuanya menunjukkan kinerja yang belum dapat dinilai baik. Dapat disimpulkan bahwa pengembangan wisata halal di Kota Banda Aceh belum terlaksana dengan baik.

Post-traumatic osteoarthritis (PTOA) is a debilitating disease that is a result of a breakdown of knee joint tissues following traumatic impact. The interplay of how these tissues influence each other has received little attention because of complex interactions. This study was designed to correlate the degeneration of the menisci, cartilage and subchondral bone following an acute traumatic event that resulted in anterior cruciate ligament (ACL) and medial meniscus tears. We used a well-defined impact injury animal model that ruptures the ACL and tears the menisci. Subsequently, the knee joints underwent ACL reconstruction and morphological analyses were performed on the menisci, cartilage and subchondral bone at 1-, 3- and 6-months following injury. The results showed that the morphological scores of the medial and lateral menisci worsened with time, as did the tibial plateau and femoral condyle articular cartilage scores. The medial meniscus was significantly correlated to the medial tibial subchondral bone at 1 month (p = 0.01), and to the medial tibial cartilage at 3 months (p = 0.04). There was only one significant correlation in the lateral hemijoint, i.e., the lateral tibial cartilage to the lateral tibial subchondral bone at 6 months (p = 0.05). These data may suggest that, following trauma, the observed medial meniscal damage should be treated acutely by means other than a full or partial meniscectomy, since that procedure may have been the primary cause of degenerative changes in the underlying cartilage and subchondral bone. In addition to potentially treating meniscal damage differently, improvements could be made in optimizing treatment of acute knee trauma.
High Density Lipoprotein Reduces Blood Pressure and Protects Spontaneously Hypertensive Rats Against Myocardial Ischemia-Reperfusion Injury in an SR-BI Dependent Manner
Authors: Al-Jarallah Aishah , Babiker Fawzi 
Published: March 2022

BackgroundHypertension is a key risk factor in the development of cardiovascular diseases. Elevation in blood pressure alters high density lipoprotein (HDL) function and composition. The exact role of HDL in cardiovascular complications observed in hypertension is however not clearly understood. HDL protected against myocardial ischemia/reperfusion (I/R) injury in normotensive rats. Nonetheless, it's not clear if restoration of HDL function and/or composition protects against myocardial I/R injury in spontaneously hypertensive rats (SHR).ObjectivesIn this study we tested the effect of HDL treatment on I/R injury in Wistar Kyoto rats (WKY) and SHR and investigated the possible underlying mechanism(s).MethodsHDL (900 ng/kg/min) or vehicle were continuously administered to 11-week old WKY and SHR for 1 week (chronic treatment). Blood pressure was measured before and after treatment. Hearts were subjected to I/R injury using a modified Langendorff system. Another set of rats were treated with HDL administered at reperfusion (acute treatment) in the presence or absence of scavenger receptor class B type-I (SR-BI) blocking antibody. Cardiac hemodynamics were computed and cardiac enzyme release and infarct size were measured. Total cholesterol (TC) and HDL-cholesterol (HDL-C) were enzymatically assayed. Markers of autophagy and inflammation were detected by immunoblotting and ELISA, respectively.ResultsHDL treatment did not increase TC or HDL-C levels in SHR or WKY, yet it significantly (P &lt; 0.01) reduced systolic and diastolic blood pressure in SHR. Chronic and acute HDL treatment significantly (P &lt; 0.05) protected WKY and SHR against myocardial I/R injury. Chronic HDL treatment was significantly (P &lt; 0.05) more protective in SHR whereas acute HDL treatment induced significantly (P &lt; 0.05) greater protection in WKY. The extent of HDL induced protection was proportional to the expression levels of cardiac SR-BI and blockage of SR-BI completely abolished HDL mediated protection in SHR. Chronic HDL treatment significantly (P &lt; 0.05) reduced markers of autophagy and inflammation in hypertensive rats.ConclusionsWe demonstrate a novel anti-hypertensive and a cardioprotective effect of HDL against myocardial I/R injury in SHR, the magnitude of which is directly related to the expression levels of cardiac SR-BI. Mechanistically, chronic HDL treatment protected SHR hearts by reducing autophagy and inflammation.

Published: March 2022

The mechanical properties of the slip zone soil play an important role in the evolution of the loess landslides. To further understand these characteristics, a series of ring shear tests was conducted on the slip zone soils obtained from Tianshuigou landslide, to investigate the influence of moisture content, dry density, shear rate and shear method on the mechanical characteristics of slip zone soils. The experimental results showed that: an increase in the moisture content of the slip zone loess causes a significant reduction in the residual strength. Specially, both the residual cohesion and residual internal friction angle show a deceasing tendency with moisture content. The change in the residual cohesion is more sensitive to the variation in moisture content. Additionally, a trend that strength increased with the increasing of dry density was observed, and the influence degree of dry density on the increased strength is more pronounced at low moisture contents. Thirdly, shear strength shows a negative relationship with shear rate when the shear rate ranges from 0.01 mm/min and 1 mm/min. When the shear rate increased up to 10 mm/min, a stepped shear band is developed and the strength increased. In addition, the strain-softening phenomenon was observed in the single-stage shear tests, which was not noticed in the multi-stage shear tests and pre-shear tests. The residual strength obtained in pre-shear test and multi-stage shear test is slightly greater than that in the single-stage shear test. The experimental results herein can provide an important basis for analyzing the evolution mechanism and prevention of loess landslides.

Published: March 2022

High-temperature hydrothermal activity areas in western Sichuan Province, China are ideal objects for studying deep Earth science, extreme ecological environments, and comprehensive geothermal utilization. To understand the geochemical characteristics of rare Earth elements (REEs) in the Chaluo hot springs in western Sichuan Province, the authors analyzed the composition and fractionation of REEs in the hot springs through hydrochemical analysis, REE tests, and North American Shale Composite-normalized REE patterns. Moreover, the composition and complex species of REEs in the geothermal water in the Chaluo area were determined through calculation and simulation analysis using the Visual MINTEQ 3.0 software. The results are as follows. In terms of hydrochemical type, all geothermal water in the Chaluo area is of the Na-HCO3 type. The cations in the geothermal water are mainly controlled by water-rock interactions and evaporation, the anions are determined by water-rock interactions, and the hydrochemical processes are primarily controlled by the dissolution of silicate minerals. The total REE content of the geothermal water in the Chaluo hot springs is 0.306 ± 0.103 ug/L. It is low compared to the Kangding area and is primarily affected by the reductive dissolution of Fe oxides/hydroxides, followed by pH. The geothermal water in the Chaluo area is rich in light rare Earth elements (LREEs) because of the presence of Fe oxides. It shows positive Eu and Ce anomalies due to the combined effects of the dissolution of Eh and Mn oxides and surface water. Furthermore, the positive Eu anomalies are also caused by the water-rock interactions between the Qugasi Formation and deep geothermal water. Similar to alkaline water bodies, the complex species of REEs in the geothermal water mainly include Ln(CO3)2−, LnCO3+, and LnOH2+, which is caused by the stability constants of complexation reactions.

IntroductionOccupational risk factors for interstitial lung disease (ILD) are a remediable aspect of this progressive pulmonary disorder. The association between firefighting and ILD is unknown. Our objective was to assess the characteristics of firefighters with ILD from a large single-center ILD registry.MethodsThe University of Chicago ILD database was reviewed for patients with a history of firefighting. Clinical information was abstracted from the medical record. The prevalence rate ratio of firefighters in the database compared to the baseline prevalence of firefighting in the Chicago metropolitan area was calculated via the Poisson distribution.ResultsNineteen firefighters were identified; all were men. A variety of ILD subtypes were seen across the cohort, including four patients with a diagnosis of connective tissue disease. Patients had mild forced vital capacity (FVC) and moderate diffusing capacity for carbon monoxide (DLCO) decrements on presentation; three patients died and two received lung transplantation over an average follow-up time of 76 months. Firefighters were seen at a greater proportion in the ILD registry than in the general population with a prevalence rate ratio of 3.98.ConclusionsFirefighting was overrepresented in our cohort compared to the general population, suggesting that there may be a causative association between firefighting and the presence of ILD. The wide variety of ILD subtypes observed suggest that all ILD patients should be asked about their occupational history. Further investigation to identify occupational exposures and determine the benefit of remediation is needed.
