Authors: Prathitasari Rahma Anindya , Isbagio Harry
Published: October 2018

Background Rheumatoid arhtirtis (RA) is a chronic autoimmune disease that mainly attacks joints. It may causes joint deformities which leads to lower quality of life of RA patients. RA is treated with metothrexate (MTX) which inhibiting disease progression. MTX is known for its hepatotoxicity side effect, which is described by an elevation of aspartate aminotransferaseÂ (AST) and/or alanine aminotransferase (ALT) beyond the upper normal limit. Factors that may enhance hepatotoxicity are gender, age, cummulative dose of MTX, and duration therapy of MTX. Prevalence of hepatotoxicity caused by MTX therapy in RA patients in Indonesia is still unknown. The objective of this research is to know the proportion of hepatotoxicity and its associations with the factors that may enhance hepatotoxicity caused by MTX therapy in RA patients in RSCM.Method Data about gender, age, cummulative dose and duration therapy of MTX are obtained from 115 RA patients' medical records.Result Proportion of hepatotoxicity in RA patients treated with MTX in RSCM is 42.60%. Gender, age, cummulative dose and duration therapy of MTX do not significantly enhance hepatotoxicity (p>0.05).Conclusion In conclusion gender, age, cummulative dose and duration therapy of MTX do not have association with hepatotoxicity in RA patients treated with MTX.Â Keywords: Rheumatoid Arthritis, Methotrexate, Hepatotoxicity

Salmonella as a causative agent in septic bursitis is considered rare. We report a case of 56 years old male with history of renal transplantation and using mycophenolate mofetil, cyclosporine and methylprednisolone as maintenance, admitted due to 3-week-fever associated with tenderness and swelling on left shoulder. Upon investigation, a diagnosis of septic bursitis was established. Salmonella enteritidis as the definitive causative agent was revealed. He was treated with meropenem 1g IV three times daily and levofloxacin 500 mg IV once a day for 3 weeks, followed by oral ciprofloxacin 500 mg twice a day for 2 weeks and oral metronidazole 500 mg three times a day for 1 week with a total duration of 5 weeks of antibiotics. On the subsequent follow up there was no recurrence episode of fever and the swelling of the left shoulder subsided, no tenderness noted and the patient has no limitation of range of movement. Since immunocompromised state complicates the management, the duration of therapy may twice longer than the typical management of septic bursitis. Salmonella as etiologic agent should be considered as differential in immunocompromised patient with septic bursitis.Keywords: Immunocompromised state, septic bursitis, deep bursae, Salmonella, duration of therapy.

It is considered the possibility of optimizing the use of the power capabilities of the cube-sat platform included in the "distributed satellite" to improve the performance of its payload. To optimize the use of energy capabilities, it was proposed to disconnect the onboard equipment of the command-and-telemetric radio link in the mode of regular operation of cube-sat in the "distributed satellite". To measure the current navigation parameters of cube-satellite in the conditions of group flight in the "distributed satellite" it is proposed to use the coordinates of the cube-satellite in the satellite coordinate system of the "distributed satellite" root satellite and the relative cube-relative velocity vector relative to the root satellite as the initial data. It is proposed to use a technique based on measurements of the distances between satellites in a "distributed satellite" and the projections of the vector of relative velocity for these distances to determine the coordinates of cube-sat in the satellite coordinate system. The features of the WiMAX broadband access protocol IEEE 802.16 protocols are examined to determine whether it is possible to perform mutual position measurements of satellites as part of a "distributed satellite" in one channel with information transmission. It pointed that the use of built-in means of measuring the range and access of mobile stations to the mobile WiMAX network makes it possible to perform measurements of the distance from the root satellite to the final satellite - cube-sat in the "distributed satellite". To perform the operations of measuring distances between the final satellites in the "distributed satellite", it is proposed to use the "competitive access zone" of the uplink sub-frame in the WiMAX network. A procedure for measuring the range between terminal satellites is proposed, based on measuring the propagation time of the distance measurement test signal between the assigned terminal satellites. It proposed a procedure for transmitting a test signal, taking into account the features of multiple access with orthogonal carrier separation (OFDMA). The proposed procedure can be implemented in a variant of the IEEE 802.16 standard network for application in a "distributed satellite"

Las habilidades sociales (HHSS) forman parte del comportamiento adaptativo del individuo. Dado que estas capacidades se desarrollan desde los primeros años de vida a través del aprendizaje social, el objetivo de este trabajo fue comparar las HHSS de niños a los dos meses de asistir al jardín de infantes que previamente habían tenido experiencia en jardines maternales (Grupo CE) con aquellos que no la tuvieron (Grupo SE). Además, se evaluó si había diferencias entre sexos. Se administró la escala de Comportamiento Preescolar y Jardín Infantil (Marrell, 2003; adaptado por Reyna & Brussino, 2009) a maestras de 35 niños de salas de 3 años de un jardín de infantes público. Se halló que los niños del Grupo CE presentaron puntajes significativamente más altos en la escala administrada que los del Grupo SE. Respecto del género, no se hallaron diferencias significativas. Estos resultados sugieren que la experiencia en el jardín maternal favorece el aprendizaje de normas sociales y la práctica de conductas socialmente habilidosas, debido probablemente a mecanismos de aprendizaje social.

Dampak pemanasan global, yaitu berupa kenaikan muka laut dengan kecepatan 2-8 mm/tahun yang tampaknya lambat dan tidak berarti, akan tetapi dalam 100 tahun mendatang kenaikan muka laut tersebut mampu untuk menggenangi kawasan pesisir P. Jawa yang memiliki morfologi pantai yang landai dan bersudut lereng kecil.
Kenaikan muka laut merupakan bencana alam yang lambat dan bisa diprediksi, namun dengan sifat yang demikian justru manusia cenderung lupa segera menanganinya. Oleh karena itu, untuk mengantisipasi kemungkinan terjadinya bencana, serta mengurangi bahkan memperkecil dampak negatif risiko bencana tersebut, perlu memasukan komponen manajemen risiko bencana alam (risk management of natural disaster) di dalam penyusunan tata ruang wilayah (RTRW).

Berdasarkan Peta Geologi Lembar Bali, daerah telitian didominasi oleh endapan volkanik. Dari rekaman seismik pantul dangkal saluran tunggal,runtunan seismik daerah telitian dapat dibagi menjadi 2 ( dua) runtunan yaitu runtunan A (di bawah) dan runtunan B (di bagian atas). Runtunan A diduga sebagai basemen. Berdasarkan sifat reflektornya di duga runtunan ini berupa batuan yang kompak dan keras, dan dapat disebandingkan dengan Formasi Ulakan . Runtunan B dicirikan oleh pola refleksi paralel. Pola refleksi ini biasanya berupa sedimen yang diendapkan pada lingkungan tenang. Kontak antar runtunan A dan B adalah kontak ketidakselarasan kontak "onlap".

Based on geological map of Bali Sheet, the study area is dominated by volcanic products. The shallow, single channel, seismic reflection records show that the seismic sequence can be divided into two sequences those are, sequence A (underneath) and sequence B (above). Sequence A is interpreted as a seismic basement. Based on its reflecting characteristics, this sequence is suggested of the hard and dense rocks, and can be correlated with the Ulakan Formation.

Arus Lintas Indonesia sering disebut dengan Arlindo, merupakan sirkulasi arus dari Samudera Pasifik menuju Samudera Hindia melalui perairan Indonesia. Sepanjang tahun, Arlindo mengalir dari Samudera Pasifik ke Samudera Hindia, akan tetapi terdapat variabilitas transpor volume. Arlindo dalam perjalanannya masuk ke perairan Indonesia, melalui Selat Makassar. Terdapat fluktuasi Arlindo di Selat Lombok yang mencapai puncaknya pada bulan Juli-Agustus 1985, kemudian berkurang pada akhir bulan Oktober 1985 hingga bulan Januari 1986. Demikian pula hasil pengamatan arus di Selat Makasar dari tahun 1996 hingga tahun 1998, terdapat indikasi arah arus ke utara meskipun tidak signifikan. Berdasarkan hasil penelitian para ahli oseanografi dan meteorologi, fluktuasi nilai transpor berhubungan dengan interaksi atmosfir dan laut. Hasil simulasi model numerik menunjukkan adanya fluktuasi nilai transpor volume di sekitar Selat Makassar, dengan penurunan nilai transpor volume ke arah selatan di sekitar Selat Makassar pada saat terjadi musim dingin di benua Asia. Nilai transpor relatif kecil pada hasil penelitian, yaitu ke arah selatan sebesar 0,5 hingga 0,7 Sv pada bulan Mei-Juni 1989 dan 0,3 Sv pada bulan Oktober tahun 1997. Nilai transpor maksimum ke arah selatan terjadi pada bulan November 1988 sebesar 14,5 Sv, dan bulan Juni 1997 sebesar 11,8 Sv. Nilai transpor berfluktuasi sesuai dengan fasa yang terjadi di Samudera Pasifik ekuatorial, yaitu fasa El NiÃ±o atau La NiÃ±a.

Indonesian Through Flow (ITF) is the current circulation of Pacific Ocean water to Indian Ocean through the Indonesian Seas. The ITF flows annualy from Pacific Ocean into Indian Ocean obtains variability in volume transport. During its journey into Indonesia Seas, ITF passes through Makassar Strait, Java Seas, and Lombok Strait. ITF shows fluctuation in Lombok Strait that reaches its peak in July-Agustus 1985, and decreases in late October 1985 to January 1986. Current observation conducted in Makasar Strait between 1996 and 1998, shows a northward current with no significant value. According to recent oceanography and meteorology researches, transport value fluctuation is associated with sea and atmospheric interaction. Numerical model simulation shows fluctuation in volume transport value in Makassar Strait where the volume decreases southward in Makassar Strait during Asian Continental winter. Transport value in Makassar Strait obtained from this research southward are 0,5 to 0,7 Sv in May-June 1989 and 0,3 Sv in October 1997. The research yielded maximum values of southward transport volume occuring in November 1988 is 14,5 Sv, and June 1997 is 11,8 Sv. Fluctuation transport values is in phase with El NiÃ±o or La NiÃ±a occuring in equatorial Pacific.

Water and soil samples were collected from five different industrial areas around Dhaka city namely, (i) Powertex Fashion Ltd., Gazipur (Textile), (ii) Shetu Pesticide Ltd., Savar (Pesticide), (iii) Salma Leather Industry, Hazaribagh (Tannery), (iv) Monno Ceramic Industries, Nayarhat, Dhamrai, (Ceramic) and (v) ACME Laboratories Ltd., Tulivita, Dhamrai (Pharmaceutical) where selected for this study. Two plants species viz. Colocasia esculenta (L.) Schott and Ipomoea aquatica Forssk. commonly growing in the industrial effluent affected areas were selected to observe the rate of heavy metal uptake. Dissolved oxygen (DO) was found below the permissible limit in all the affected areas (lowest 0.88 mg/l in tannery waste affected areas) indicating high amount of organic wastage discharge from tannery. Eight trace metals viz. arsenic, cadmium, nickel, iron, zinc, chromium, copper and lead were analysed for water, soil and plant samples. Arsenic and cadmium exceeded the permissible limit in water sample collected from all affected areas. Tannery waste affected area was found to be the most vulnerable area in respect to arsenic and chromium contamination. On the other hand, the highest amount of arsenic was found in the soil sample collected from pesticide affected area. The rate of heavy metal uptake in Colocasia esculenta (L.) Schott is much higher than Ipomoea aquatica Forssk. More heavy metals were accumulated in edible portion than roots of the plants.
Management of Bakanae disease of rice
Authors: Hossain KS , Mia MAT , Bashar MA
Published: October 2018

Bakanae disease is widely distributed in all rice growing areas of the world. In Bangladesh, it is one of the major diseases of rice. Four methods were tested for management of this disease, of which, roguing proved ineffective in a field investigation. Among the 15 fungicides tested in vitro, all of them were found effective in various degrees against the pathogen of the disease. Best effective 4 were selected for seed treatment and know (50% carbendazim WP) was the most effective followed by folicur (25% Tebuconazole EC), protaf (25% Propiconazole EC) and celest extra (2.5% Fludioxonil and 2.5% Difenoconazole EC). In the field, foliar spray of folicur, knowin and protaf was found ineffective to control bakanae disease. Looking for resistant one, 46 BRRI released varieties, “Purbachi”- a Chinese variety and 40 landraces of BRRI germplasm were tested in vitro against the pathogen. All these varieties and landraces were susceptible to the test pathogen in various degrees. Among the released varieties lower susceptibility were found in BR 23 and BR 11. Whereas, among the varieties and landraces the lowest was found in A23. Therefore, A23 may be suitable for use in the development of varieties resistant to bakanae rice disease.
