Understanding vitamin B12 and folate deficiency
Authors: Perry Margaret 
Published: February 2020

Vitamin B12 and folate deficiencies are common and have a big impact on sufferers' lives. Margaret Perry provides an overview of the causes of, and treatments for, these conditions Vitamin B12 and folate are essential for a number of physiological functions in the body. Deficiency of vitamin B12 is relatively common and prevalence increases with age. Folate deficiency is less common, but still clinically significant. Diagnosis can often be problematic as many of the symptoms patients present with are shared with other conditions and can easily be attributed to other causes. Mild deficiency of B12 may cause no symptoms until it has progressed to be more severe. Interpretation of B12 levels is extremely difficult as there is no clinically normal level. Diagnosis can be easily overlooked, but correct treatment has the ability to transform sufferer's lives in terms of improving energy levels and preventing further complications.

Abstract. Yudaputra A. 2020. Modelling potential current distribution and future dispersal of an invasive species Calliandra calothyrsus in Bali Island, Indonesia. Biodiversitas 21: 674-682. Calliandra calothyrsus Meisn. is relatively well-adapted in abandoned areas, degraded lands, and poor nutrient soils. It tends to reproduce rapidly and be invasive in certain landscapes as it often dominates the vegetation. This study aimed to understand the potential current distribution and the population dispersal of C. calothyrsus across Bali Island using Random Forest (RF) and Maximum Entropy (MaxEnt) models. Thirteen environmental variables, including several climatic variables, topography, soil characteristics were used as predictors. The occurrence records of C. calothyrsus were obtained from direct field survey in which square plots 10 x 10 m were used to collect the population structure data. The Rangeshifter software was used to understand the population dynamic and dispersal pattern. The results showed that the two models (RF and MaxEnt) have the AUC>0.9 which means those models are excellent in predicting the potential current distribution of C. calothyrsus. Furthermore, the RF model has the TSS and Kappa value of >0.90 which means it has almost perfect agreement between the prediction and the real observation. On the other hand, the TSS and Kappa value of MaxEnt were >0.70 indicating it has a substantial agreement. The population structure in the field showed that the number of juvenile individuals dominated all plots compared to seedlings and mature individuals. The simulation analysis showed that the population tends to have bigger population in the next 50 years by dispersing throughout neighbor cells or areas in which the origin occurrence points were recorded.

Abstract. Nelly N, Khairul U, Putri AY, Hamid H, Syahrawati MY. 2020. Isolation and selection of maize plants rhizobacteria with the potential of entomopathogens against Spodoptera litura F (Lepidoptera: Noctuidae). Biodiversitas 21: 753-758. Spodoptera litura is a polyphagous pest that can be controlled with entomopathogen. Furthermore, Rhizobacteria derived from the rhizosphere of corn plants are expected to control this pest. This research, therefore, was conducted to obtain the entomopathogenic rhizobacteria to control S. litura derived from the rhizosphere of corn plants. Data sampling was carried out at corn plantations in West Pasaman Regency, while Isolation, selection, and testing of S. litura were conducted at the Biological Control Laboratory of the Plant Protection Department, Faculty of Agriculture, Andalas University. The method uses serial glowing techniques cultured on Nutrient Agar (NA) media, with the selected isolates tested for their ability as an entomopathogen against S. litura. The feed dip method given to S. litura larvae was used to test for rhizobacteria virulence determination with entomopathogen, used to observe the larvae mortality rate, percentage of pupae, and adult formed. Furthermore, observation of morphological and physiological characters was conducted on entomopathogenic rhizobacteria, with hypersensitive testing conducted on Mirabilis jalapa plants. The results of rhizobacterial isolation from corn rhizosphere obtained 12 entomopathogenic isolates. Deadly larvae of S. litura 51-91.11%, 0.00-8.89% pupae, and 0.00- 6.67% adult were formed. The gram test results obtained approximately 8;4 positive (+) and four negative isolates (-), respectively. Hypersensitivity test results found that one of 12 isolates caused necrotic reactions in Mirabilis jalapa. Therefore, a total of 11 rhizobacteria isolates are entomopathogenic and safe to be used as S. litura biological control agents.

Abstract
Acute kidney damage associated with pregnancy occurs in 1/20.000 pregnancies. In developing countries, the main cause of the development of acute kidney damage is septic abortion, and preeclampsia in the developed countries of the world. Preeclampsia is defined as newly developed hypertension, proteinuria and swelling in pregnant women after the 20th week of gestation. It occurs due to disorders in the development of placenta and systemic disorders of the function of the endothelium of the mother. It is treated with methyldopa, magnesium sulfate and timely delivery. Urgent delivery is indicated if the age of gestation is ≥ 34 weeks. HELLP syndrome is a difficult form of preeclampsia. Its main characteristics are decreased platelet count, microangiopathic hemolysis anemia, increased concentration of aminotransferase in the serum and acute kidney damage. Severe HELLP syndrome is treated with emergency delivery, antihypertensives, magnesium sulfate, and in some cases plasmapheresis and hemodialysis. Acute fatty liver in pregnancy occurs because of decreased activity of the LCHAD enzyme of the fetus. Due to the reduced beta oxidation of fatty acids in the hepatocytes of the fetus, long chain fatty acids that cause damage to the mother’s hepatocytes are released. Swansea criteria are used for diagnosis, and the difficult form of the disease is treated with plasmapheresis and extracorporeal liver support. Atypical HUS is due to a reduced protein activity that regulates the activity of the alternative pathway of the complement system. Its main features are thrombocytopenia, microangiopathic hemolytic anemia and acute kidney damage. It is treated with plasmapheresis, and in case of resistance with eculizumab. Thrombotic thrombocytopenic purpura is due to decreased activity of the ADAMTS13 enzyme. It is characterized by thrombocytopenia, microangiopathic hemolytic anemia, high temperature, nervous system disorders and acute kidney damage. It is treated with plasmapheresis, and severe form of disease with corticosteroids and azathioprine. Early detection and timely treatment of acute kidney damage provides a good outcome for the mother and fetus.

Published: February 2020

AbstractBehl’s method is one of the iterative methods to solve a nonlinear equation that converges cubically. In this paper, we modified the iterative method with real parameter β using second Taylor’s series expansion and reduce the second derivative of the proposed method using the equality of Chun-Kim and Newton Steffensen. The result showed that the proposed method has a fourth-order convergence for b = 0 and involves three evaluation functions per iteration with the efficiency index equal to 41/3 = 1.5874. Numerical simulation is presented for several functions to demonstrate the performance of the new method. The final results show that the proposed method has better performance as compared to some other iterative methods.Keywords: efficiency index; third-order iterative method; Chun-Kim’s method; Newton-Steffensen’s method; nonlinear equation.

Studi Literatur Radiolisis Air Ringan dan Pengukuran Laju Dosis Bahan Bakar Terhadap Jarak Sumber Radiasi Pada Kolam Penyimpanan Bahan Bakar Bekas (ISSF). . Elemen bahan bakar bekas masih mengandung sejumlah uranium diperkaya dengan paparan radiasi yang sangat tinggi, sehingga digunakan air sebagai media penyimpanan bahan bakar bekas pada kolam ISSF agar paparan radiasi bahan bakar tidak keluar ke lingkungan.Paparan radiasi dalam air dapat menyebabkan adanya pembentukan oksidator yang dapat menyebabkan korosi pada material bahan ISSF. Laju dosis dapat terukur dalam suatu sumber radiasi terhadap besarnya penahan radiasi. Laju dosis ini digunakkan sebagai input parameter untuk reaksi radiolysis sehingga konsentrasi pembentukan oksidator dalam air dapat diprediksi. Hubungan antara laju dosis teradap jarak sumber radiasi (tebal penahan) menjadi penting untuk penerapan proteksi radiasi. Metode untuk mengukur laju dosis pada kolam ISSF dilakukan pada rak bahan bakar bekas serta uji cicip pada sebuah kelongsong bahan bakar bekas. Laju dosis diukur dengan detector radiagem dengan kabel yang terbungkus plastik. Data hasil percobaan didapatkan bahwa hubungan antara laju dosis radiasi terhadap sumber radiasi yaitu semakin besar jarak detektor terhadap sumber radiasi semakin kecil laju dosis yang terukur dan bersifat eksponensial.Kata Kunci : Kolam ISSF, radiasi, radiolysis air, laju dosis, detector

ANALISIS KRITIKALITAS TINGGI TERAS AKTIF HTGR-10MWth DENGAN VARIASI PENGAYAAN PADA KERNEL URANIUM OKSIDA. HTGR-10MWth merupakan salah satu bentuk dari reaktor HTGR tipe pebble bed. Reaktor jenis ini memiliki reaktivitas negatif sebagai fungsi keselamatan melekatnya. Dalam fisika reaktor, parameter kritikalitas merupakan faktor penting untuk mengetahui kondisi kekritisan reaktor, yang menjadi penentu apakah reaktor dapat beroperasi atau tidak. Kritikalitas pada teras aktif suatu reaktor sangat dipengaruhi oleh ketinggian teras aktif, tingkat pengayaan bahan bakar, geometri teras reaktor dan parameter lainnya. Tujuan dari penelitian ini adalah untuk mendapatkan parameter neutronik yang sesuai agar reaktor dapat beroperasi secara optimal. Metodologi yang dilakukan adalah dengan melakukan pemodelan kernel berlapis TRISO dengan model berbentuk kisi-kisi SC (simple cubic), dan pemodelan geometri reaktor. Bahan bakar dan moderator pebble pada teras reaktor dimodelkan dalam bentuk kisi BCC (body-centered cubic) dengan rasio perbandingan pebble bahan bakar dan pebble moderator sebesar 57:43. Paket program MCNP6 digunakan dalam analisis ini. Dari hasil perhitungan, didapat bahwa tinggi teras aktif kritis awal untuk pengayaan 17 % adalah 125 cm, pengayaan 14 % setinggi 141 cm, pengayaan 12 % adalah 161 cm dan pengayaan 10 % adalah 196,1 cm. Sementara, tinggi teras aktif penuh untuk pengayaan 8 % melebihi batas tinggi teras yang tersedia.

Abstract
The positive health effects of yoga have led physical therapists (PTs) to integrate elements of the discipline into their treatments in some settings. Formal PT education includes limited, if any, training in yoga, and there is no system in place to provide education on safely implementing therapeutic yoga (TY) as an adjunctive treatment approach. The purposes of this study were to: (1) assess the readiness of PTs (those who do not currently prescribe TY to patients) to integrate TY into treatment, and (2) determine the feasibility of a 5-week online TY training to improve the readiness of PTs to utilize TY in their practices. Licensed PTs (n = 103) were recruited nationally through social media and email. Eligible and consented PTs registered for a 5-week online TY training course. PTs’ perceptions of TY and the role of safety and confidence in prescribing TY to patients were measured at baseline and postintervention. Feasibility outcomes were measured after completion of the course. Benchmarks included: (1) &gt; 70% of PTs would find the course acceptable; (2) &gt; 60% would finish the course; and (3) there would be significant improvements in PTs’ perceptions of TY. A total of 95 eligible PTs consented and registered for the course, with 60 (63.1%) completing the intervention. Prior to the training, most PTs felt they were not ready (n = 19/60, 31.7%) or somewhat ready (n = 25/60, 41.7%) to integrate TY. More than half thought the online training was acceptable (n = 50/60, 83.3%) and finished the course (n = 60/95, 63.1%). There were significant improvements in personal readiness and confidence to safely prescribe TY, current understanding/knowledge of TY, and feeling adequately trained to use some form of TY with patients. A 5-week online TY training course is feasible to deliver for improving PTs’ readiness to prescribe TY. Future studies are proposed to test the effectiveness of TY training and education with PTs.
