Published: May 2019

Tsamaroh Nidaa Putri, Priyo Sasmoko explains that accumulator is a combination of several pieces of cells used for altering the chemical energy into electricity energy used in motor vehicles. Accumulators are used continuously will shrink and drop so it needs to be recharged. To know the state of the battery voltage drop experienced the need for a measurement to determine the ability of the accumulator. Design manufacture accumulator discharge monitoring tool consists of a voltage divider circuit to know the big accumulator voltage in percentage form. Used also an ACS712 current sensor to detect the discharge current and LM35 temperature sensor to determine the temperature of the accumulator. The control system used is the Arduino UNO microcontroller and an LCD for displaying the measurement data. Normal voltage ranges accumulator 12,5V - 13,8V. Accumulator with a capacity of 5Ah takes 8 hours to process discharge when using 20 watt lamp load. If the voltage of the first accumulator on the LCD shows the percentage of 0 % then automatically the system will work to discharge for a second accumulator. The duration of use depends on the large accumulator load used. Keyword:Accumulator, ACS712, capacity accumulator, Arduino UNOReferencesAgustin, Leonandi. 2015.

Published: May 2019

Ade Siti Sarah Azhar, Eko Ariyanto in this paper explain that Coffee is one of the most popular drinks ever in the history of human civilization. Roasting is one of the most important processes in processing coffee beans that serves to determine the process of forming flavors and aromas in coffee beans. The average roasting process still uses manual methods, so an automatic coffee roaster machine is needed that can support the home roasting process which is equipped with a round control system. It is expected that the roasting process can be carried out quickly. The use of automatic roasting machines aims to save energy and cost and time efficiency. The round control system in this coffee roaster machine uses PWM (Pulse Width Modulation) to regulate speed on a DC motor by regulating the PWM signal which can be done in analog or by using a microcontroller.By using a motor driver, the motor rotation direction can be controlled. When the DC motor rotates its rotation speed can be detected by an optocoupler which then outputs from the optocoupler will send and process data to the Atmega microcontroller 16. The performance of this control system uses a rotation above 60 Rpm with regulated temperatures above 100 ° C. The performance of this control system gets variations in the results of roasting of coffee beans that are close to the standard of coffee, namely at the rotation of 65 Rpm with a temperature of 130 ° C and the roasting time of 18 minutes with the color of Light Roast coffee beans.

Pengaruh Dexmedetomidine Intravena Terhadap Kadar Superoxide Dismutase 1 (SOD-1) Otak Kelinci Pada Cerebral Ischemic Reperfusion Injury Model
Authors: Tetuko R. A. Nino , Jatmiko Heru Dwi , Arifin Johan 
Published: May 2019

Latar Belakang : Dexmedetomidine adalah agonis α2-adrenergik reseptor (α2-AR) yang selektif dan ampuh, menunjukkan sifat sparing anestesi, analgesia dan sifat simpatolitik, termasuk digunakan sebagai agen pelindung untuk Ischemic Reperfusion Injury (IRI). Superoxide Dismutase 1 (SOD-1) memainkan peran penting dalam menyeimbangkan status oksidasi dan antioksidan, memberikan pertahananpenting terhadap toksisitas superoksida radikal, sehingga dapat melindungi sel dari kerusakan.Ischemia Reperfusion Injury dapat dihasilkan dari berbagai faktor seperti pelepasan radikal oksigen bebas dan berturut-turut oleh peroksidasi lipid, kematian sel oleh apoptosis atau nekrosis, inflamasi sitokin, dan kerusakan vaskularisasi mikro. Spesies oksigen reaktif yang muncul dengan cedera reperfusi merusak struktur selular melalui proses peroksidasi lipid dari membran sel dan hasil metabolit beracun seperti malondialdehyde (MDA).Tujuan : Mengetahui efek dexmedetomidine intravena terhadap kadar Superoxide Dismutase 1 (SOD-1) otak kelinci dengan cerebral ischemic reperfusion injury model.Metode : Penelitian eksperimental Randomize Post Test Only Control Group Design menggunakan 10 ekor kelinci New Zealand. 5 ekor kelinci diberikan perlakuan dengan pemberian dexmedetomidine 0,5 mcg/kgbb/jam dan dilakukan oklusi pada arteri karotis interna (K1). 5 ekor kelinci yang tidak mengalami perlakuan (KK) juga dilakukan oklusi arteri karotis interna dan dilakukan pemeriksaan Superoxide Dismutase 1 (SOD-1) sebagai control.Uji normalitasdengan Saphiro Wilk dilanjutkan uji parametric menggunakanIndependent T-test.Hasil : Kadar rerata SOD-1 pada kelompok kontrol 0,47±0,23 dan nilai P 0,273 (normal) dan kadar rerata SOD-1 pada kelompok perlakuan 1,00±0,29 dan nilai P 0,422 (normal). Uji beda digunakan uji parametric Independent T-test didapatkan nilai p = 0,013. Karena nilai p < 0,05 maka dapat disimpulkan terdapat perbedaan bermakna.Kesimpulan : Dexmedetomidine secara signifikan meningkatkan nilai Superoxide Dismutase 1 (SOD-1) pada kelinci New Zealand yang diberikan perlakuan oklusi pada arteri karotis interna.

Berdasarkan data Pendapatan Nasional Indonesia 2017, sektor pertambangan dan penggalian mempunyai peran penting bagi Indonesia. Sektor ini menyumbangkan 7,57% pada produk domestik bruto Indonesia di tahun 2017 . Salah satu sektor pertambangan yang potensial di Indonesia adalah pertambangan mineral Timah di Pulau Bangka dan Belitung. Namun kegiatan pertambangan ini banyak menimbulkan dampak negatif dari sisi lingkungan. Salah satu upaya awal untuk menanggulangi dampak negatif terhadap lingkungan adalah melakukan identifikasi kawasan pertambangan timah secara spasial. Teknologi yang dapat membantu untuk hal ini salah satunya adalah teknologi penginderaan jauh radar. Penelitian ini menggunakan data satelit radar sentinel-1 yang diluncurkan oleh European Space Agency (ESA). Tujuan penelitian ini adalah pemanfaatan data radar Sentinel-1 untuk identifikasi kawasan pertambangan menggunakan metode Object-Base Image Analysis (OBIA). Data sentinel-1 disegmentasi menggunakan algorithma multiresolution segmentation kemudian di klasifikasi menggunakan algorithma nearest neighbor. Masukan data yang digunakan untuk proses klasifikasi dibuat menjadi dua variasi, yang pertama adalah data standar deviasi, mean, dan brightness pada masing – masing segmen di tiap band, kemudian variasi kedua adalah penambahan data tekstur berupa nilai grey level coocurance matrix (GLCM). Hasil klasifikasi menunjukan bahwa masukan data yang menggunakan data tekstur GLCM mempunyai akurasi lebih tinggi dibandingkan dengan yang tanpa data tekstur GLCM. Secara statisktik Hasil klasifikasi dengan type satu menunjukan bahwa total akurasi nya adalah sebesar 89,0 %, dengan nilai kappa sebesar 0,48 sedangkan untuk type dua menunjukan bahwa total akurasinya adalah 89,3%, dengan kappa sebesar 0,50. Hasil klasifikasi kawasan pertambangan dapat digunakan sebagai masukan awal dalam rangka identifikasi spasial kerusakan lingkungan akibat aktivitas pertambangan.

Meta-analysis: compared with anti-CCP and rheumatoid factor, could anti-MCV be the next biomarker in the rheumatoid arthritis classification criteria?
Authors: Zhu Jia-Ning , Nie Liu-Yan , Lu Xiao-Yong , Wu Hua-Xiang 
Published: May 2019

Abstract

Background
Previous reviews of the diagnosis for rheumatoid arthritis (RA) have not compared anti-mutated citrullinated vimentin (MCV) with anti-cyclic citrullinated peptide (CCP) and rheumatoid factor (RF) in respect of sensitivity, specificity and the area under the curve (AUC) against disease controls for differential diagnosis. This meta-analysis aims to evaluate the value of anti-MCV in the diagnosis for RA, the combined sensitivity of anti-MCV and anti-CCP, and certain clinical characteristics related to the performance of anti-MCV.

Methods
Medline, Embase, Cochrane Library and Web of Science were searched for articles published up to 25 August 2018. A total of 33 studies including 6044 RA patients and 5094 healthy or disease controls achieved inclusive criteria. QUADAS-2 was applied to evaluate the quality of the included studies. The bivariate random effects model was employed in primary data synthesis to evaluate the diagnostic performance.

Results
The sensitivity of anti-MCV, anti-CCP and RF in RA diagnosis against a disease control group was 0.71, 0.71, 0.77, with the specificity of 0.89, 0.95, 0.73, and the AUC of the SROC of 0.89, 0.95, 0.82, respectively. The predesign of the primary study and diagnostic criteria were statistically significant as sources of heterogeneity. Anti-MCV and anti-CCP tests demonstrated a sensitivity of 0.77 when performed in parallel, with a sensitivity of 0.60 when performed in series; whereas, the combination of anti-MCV and RF presented a sensitivity of 0.64 when used in series.

Conclusions
Anti-MCV demonstrates comparable diagnostic value to anti-CCP and RF, thus it can be an effective diagnostic marker for RA and may be written into the next authoritative criteria.

Published: May 2019

Abstract

Background
Wolcott-Rallison syndrome is a rare autosomal recessive disorder characterized by neonatal/early-onset non-autoimmune insulin-dependent diabetes, multiple epiphyseal dysphasia and growth retardation. It is caused by mutations in the gene encoding eukaryotic translation initiation factor 2α kinase 3 (EIF2AK3). We aimed to study the clinical characteristics and frequency of the disease in the Iranian population.

Methods
We recruited 42 patients who referred to the endocrine and metabolism clinic at Mashhad Imam Reza Hospital with neonatal diabetes. Molecular screening of KCNJ11, INS, ABCC8 and EIF2AK3 was performed at the Exeter Molecular Genetics Laboratory, UK. We calculated the frequency of the disease in 124 patients referred from Iran to the Exeter Molecular Genetics Laboratory for genetic screening and compared it to other countries worldwide.

Results
We identified seven patients as having Wolcott-Rallison syndrome. Genetic testing confirmed the clinical diagnosis and indicated five novel mutations. Only two patients developed clinical features of the syndrome by 6 months of age. Of all 124 cases of Iranian neonatal diabetes referred to the Exeter Molecular Genetics Laboratory for genetic screening, 28 patients (22.58%) had a recessive mutation in EIF2AK3.

Conclusions
The results of this study raises awareness of the condition and provides further accurate data on the genetic and clinical presentation of Wolcott-Rallison syndrome in the Iranian population. Our study highlights the importance of genetic testing in patients from consanguineous families with diabetes diagnosed within the first 6 months of life.

Published: May 2019

Abstract

Background
Phenylketonuria (PKU) management practices differ between and within countries. In 2007, the Portuguese Society for Metabolic Disorders (SPDM) approved the Portuguese Consensus (PC) for the nutritional treatment of PKU. The recently published European PKU Guidelines (EPG, 2017) systematically reviewed recent evidence and aimed to harmonise treatment protocols in Europe. The objective of this study was to appraise the EPG acceptance and implementation in Portuguese treatment centres.

Methods
An electronic questionnaire was prepared and the link was sent to 135 SPDM members. It outlined the 10 EPG key recommendations and compared each statement with the consensus recommendations published by SPDM. Responses were recorded and descriptive analyses were performed.

Results
Twenty-five professionals completed the questionnaire, and over half (56%) were nutritionists/dieticians. At least one questionnaire from each of the 10 national treatment centres was returned. In general, responders accepted most of the recommendations. However, only the recommendation about target phenylalanine (Phe) concentrations between 120 and 360 μmol/L for patients <12 years received 100% consensus with a further seven recommendations gaining over 70% consensus. Almost half of the professionals (48%, n = 12) required further discussion about the EPG-safe upper target blood Phe concentration (600 μmol/L) suggested for patients aged ≥12 years. Almost one third (32%, n = 8) failed to agree with the recommendation in the EPG-proposed classification of Phe hydroxylase (PAH) deficiency.

Conclusions
The EPG received overall good acceptance, but there was divided opinion about some recommendations which require further discussion before implementation by the Portuguese treatment centres.
PCOS diagnosis in adolescents: the timeline of a controversy in a systematic review
Authors: Vassalou Helen , Sotiraki Marianthi , Michala Lina 
Published: May 2019

Abstract

Study objective
Polycystic ovary syndrome (PCOS) in adolescence, a disorder of exclusion, has proved to be a timeless diagnostic challenge for the clinician. Since 1990, several attempts to provide clear diagnostic criteria have been published, most of the time leading to inconsistencies. We attempted to elucidate the controversies and convergences of this subject by conducting a systematic review of the literature concerning official guidelines or proposed criteria for the diagnosis of PCOS in adolescent girls.

Design
Based on a term search sequence via electronic databases such as Pubmed, Cochrane, Embase, Scopus and a hands-on review of references and learned societies, all available data were classified and analyzed. Single case reports, original studies with adult population or articles with incomplete diagnostic guidelines were excluded.

Results
Twelve reports dated from 2006 to 2018 fulfilled the inclusion criteria. Seven of them were endorsed or published by learned societies. All suggested a stricter diagnosis than in adulthood. Polycystic ovarian morphology was used as a necessary criterion only in three guidelines, and there was a tendency for a more objective diagnosis of hyperandrogenism, defined either by clinical features or by biochemical hyperandrogenemia, although in one case both were required.

Conclusion
Irregular menstrual cycles, allowing for an interval of at least 2 years postmenarche, and hyperandrogenism, usually reinforced by biochemical confirmation, are the main accepted features for PCOS diagnosis in adolescence. Discrepancies among endocrine and reproductive medicine societies still remain, although recent intensified attempts at reaching a consensus should allow for more universally accepted diagnostic criteria.

AbstractObjectivesTo determine the relationship between the intensity of the intra-amniotic inflammatory response and the gestational age at the time of diagnosis in cases with preterm premature rupture of membranes (PROM) and intra-amniotic infection caused byUreaplasmaspp.MethodsA retrospective cohort study was conducted which included 71 women with preterm PROM and a positive amniotic fluid culture withUreaplasmaspp. Women with mixed intra-amniotic infections were excluded. The study population was classified into three groups according to gestational age: group 1, <26 weeks (extreme preterm PROM, n = 17); group 2, 26.0–33.9 weeks (moderate preterm PROM, n = 39); group 3, 34.0–36.9 weeks (late preterm PROM, n = 15). The intensity of the intra-amniotic and maternal inflammatory response was compared among the three groups. The intensity of the intra-amniotic inflammatory response was assessed by the concentration of amniotic fluid matrix metalloproteinase-8 (MMP-8) and white blood cell (WBC) count. The maternal inflammatory response was assessed by the concentration of C-reactive protein (CRP) and WBC count in maternal blood at the time of amniocentesis.Results(1) The median values of amniotic fluid MMP-8 concentration and WBC count were the highest in the extreme preterm PROM group and the lowest in the late preterm PROM group (P < 0.001 and P = 0.01, respectively); (2) the intensity of the maternal inflammatory response measured by maternal blood WBC count and CRP concentration was not significantly associated with gestational age at the time of diagnosis.ConclusionThe earlier the gestational age at the time of PROM, the higher the intensity of the intra-amniotic inflammatory response in women with preterm PROM and intra-amniotic infection caused byUreaplasmaspp.

AbstractObjectiveTo compare myocardial strain and mechanical dyssynchrony in fetuses with congenital heart disease (CHD) to normal controls using speckle tracking echocardiography (STE).MethodsIn this comparative cross-sectional study 23 fetuses with CHD and 105 normal controls between 19 and 41 weeks of gestation were assessed with STE. The STE sample box was placed over the myocardium of both ventricles. The parameters of interest included the segmental strain of the left (LV-S) and right lateral ventricle wall (RV-S) and the global ventricular strain of both chambers (2C-S). In order to separately assess the LV, we placed the STE sample box over the myocardium of the LV. We calculated the strain of the LV lateral wall (LW-S), the septum (SEPT-S) and the global ventricular strain of the single LV (1C-S). Furthermore, we analyzed the differences in timing of negative peak myocardial strain between the LV and RV (two-chamber dyssynchrony, 2C-DYS) and also within the LV between the lateral wall and the septum (one-chamber dyssynchrony, 1C-DYS).ResultsThe evaluation of strain and mechanical dyssynchrony was feasible in all cases. Compared to normal controls, fetuses with CHD showed lower segmental and global strain values and the extent of 2C-DYS and 1C-DYS was higher than in the healthy control group.ConclusionThe deterioration of myocardial function in CHD can be measured with STE. The assessment of strain and dyssynchrony with STE may be useful for distinguishing fetuses with CHD from healthy fetuses.
