ABSTRACTSecondary iron overload in thalassemia major occurs due to ineffective erythropoiesis and periodic transfusions. The excess of iron exceed transferrin so there are many non transferrin bound iron NTBI that induce tissue damaging free radical ion. Accumulation of iron in intestine can lead to changes in the function, organ damage, lack of amino acid availability. Iron overload can be reduced by iron chelation. Transferrin is the body 39 s natural chelator comprising of dominant amino acid alanine, leucine, glycine, aspartic acid. Research found that transferrin were lower in iron overload patients. This study aims to acquire the changes of iron status, amino acid profile, and correlation between iron overload and amino acid profile. Studied parameter were serum iron, unsaturated iron binding capacity UIBC , total iron binding capacity TIBC , ferritin, transferrin saturation, transferrin index, alanine, leucine, glycine, aspartic acid.

Significant amino acid profile changes decreased of alanine and leucine, and glycin increased after 1 month chelation. There rsquo s significant correlation between transferrin index and alanine pre transfusion. There rsquo s significant correlation between transferrin index and alanine, glycine after 3 month chelation. "

"Ruang Lingkup dan Cara Penelitian: Adenosin Trifosfat (ATP) sintase berfungsi sebagai tempat sintesis ATP dari ADP dan Pi dengan menggunakan energi gradien proton. Kompleks ATP sintase marupakan satu dari enzim penting yang sangat diperlukan untuk metabolisme sel secara umum. Enzim ini terdiri dari dua bagian, yaitu bagian yang mengandung situs katalitik (F1) dan bagian proton channel (F0). Subunit β dari F1 merupakan salah satu subunit kunci karena memiliki situs aktif atau situs katalitik bagi ATP dan merupakan protein yang highly conserved memiliki 70 % homologi antara manusia dengan E. coli, yang memberikan indikasi akan pentingnya bagian tersebut. Saat ini telah diketahui secara lengkap dua sekuens gen ATP sintase subunit β yaitu dari Ohta S. et al.(1988) dan Neckelmann et. al. (1989) yang menunjukkan adanya variasi polimorfik. Karena perbedaan sekuens dapat mempengaruhi ekspresi dan fungsi protein ATP sintase subunit β dalam metabolisme energi mitokondia, dan mungkin berasosiasi dengan keadaan patologis tertentu, maka dalam penelitian ini dilakukan studi untuk mencari bukti adanya variasi polimorfik ATP sintase subunit β dengan memanfaatkan keragaman etnik di Indonesia. Sekuens DNA dari gen ATP sintase subunit β ditentukan dengan menentukan disain primer dan mengamplifikasi daerah penyandi asam amino (ekson 1 sampai dengan ekson 10) dari gen tersebut. Penapisan varian polimorfik dilakukan dengan metode PCR-RFLP. Hasil dan Kesimpulan: Hasil sekuens DNA pada dua individu populasi Indonesia ternyata serupa dengan sekuens Neckelmann dan memiliki banyak perbedaan dengan sekuens Ohta. Dari hasil metoda PCR-RFLP serta analisis hasil sekuensing ini ditemukan adanya delapan artefak sekuens pada daerah penyandi asam amino pada sekuens gen ATP sintase subunit β hasil publikasi Ohta S. et al. Oleh karena itu sekuens gen ATP sintase subunit β hasil publikasi Ohta S. et. al. tidak dapat digunakan sebagai sekuens referensi. Dengan menggunakan sekuens referensi baru ditemukan adanya polimorfisme pada sekuens gen ATP sintase subunit β pada etnik Jawa dengan frekuensi 20 % dan frekuensi alel 10%. Varian polimorfik baru yang ditemukan, mengakibatkan perubahan asam amino dari prolin menjadi leusin (P12L). Perubahan asam amino P12L dari ATP sintase subunit β ini terletak pada daerah presekuens sehingga tidak berpengaruh terhadap struktur maupun fungsi dari ATP sintase subunit β akan tetapi mungkin berpengaruh pada efektivitas penghantaran protein subunit β ke membran dalam mitokondria. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa: (1) Sekuens Ohta tidak dapat digunakan sebagai sekuens referens karena mengandung sejumuah artefak. (2) Konservasi gen ATP sintase subunit β tinggi karena sebagian besar populasi Indonesia termasuk Papua sama dengan populasi Kaukasia dan Jepang. (3) Ditemukan polimorfisme baru pada sekuens gen ATP sintase subunit β (P12L) pada populasi etnik Indonesia dengan: (a) alel frekuensi polimorfisme pada populasi Jawa sebesar 10%, (b) terdapat perubahan asam amino yang non konservatif, (c) P12L terdapat pada daerah presekuens yang unik untuk manusia. (4) Ada empat kumparan heliks yang memperlihatkan adanya gambaran amfipatik."

"Rhizopus oryzae is known to produce lactic acid, protease and lipase, make it potential as a starter in cheese production. However, R oryzae aplication in the unripened cheese production has not been elucidated. In this research, microbiology and nutritional status of unripened cheese fermented by R. oryzae was analysed and compared to that of the cheese made by rennet as a control. Total Plate Count of bacteria in unripened cheese fermented by R. Oryzae was 8.1 x 10 cfuml in PCA medium and 3.7 x 10 cfu/ml in MRSA. Total Count of fungi group was conducted using PDA, resulting in 1.2 x 10 cfu/ml. Dominant microflora were identified as Eterococcus faecalis and Bacillus subtilis in MRSA and Aspergillus sp. in PDA. HPLC analysis of the unripened cheese fermented by R. oryzae showed that it had higher essential amino acid content than the control. The essential amino acid found were Threonine (1,15 ppm), L-Methionine (0,47 ppm), L-Valine + L-Tryptophan (0,70 ppm), L-Phenylalanine (0,66 ppm), L-Isoleucine (0,48 ppm), L-Leucine (1,28 ppm), and L-Lycine (1,64 ppm)."

"ABSTRACTThe bacterial blight (BB) disease severity on two rice genotypes i.e.; BP 4110-2d-33 (backcross between Ciherang x Angke; containing Xa-4, xa-5) and BP 3688e-23 (sister lines derived from cingri/memberamo//widas///IRBB 8; containing xa-8) were lower compare with TN-1 (containing Xa-14). The total amino acid content in cultivar?s TN-1 was accounted for about one third to about a half of total amino acid than those of other rice genotypes where the totalamino acid was ranging from 1.95% to 4.22%. In BP 3688e-23, and BP 3688e-22 genotypes more amino acid levelswere decline although these advance lines showing xa-8background. BB resistant gene carried by BP 4110-2d-33 andBP 3688e-23 were stable, whilst BP 3688e-22 was less effective to inhibit BB disease severity. Overall, amino acidswere not found to be related to the level of BB resistance; where correlation between amino acid content and BBdisease severity is not significant. The slower growth of Xoo on rice genotypes BP 4110-2d-33 and BP 3688e-23 mayprobably due to other than nutritional factors. The degree of resistance in rice genotypes infected by races of pathogen;as well as the resistance gene possessed by genotype BP 3688e-23 need to be further determined. "

"During exercise, levels of several hormones are acutely increased in the blood. We previously reported that pre-exercise ingestion of a specific combination of amino acids (arginine, alanine, and phenylalanine; A-mix) increases fat mobilization and ketone body synthesis by increasing secretion of adrenalin and glucagon in healthy active young men. Herein, we sought to determine whether this acute hormone response could be induced upon administration of A-mix combined with exercise in patients with obesity during periods of low-intensity exercise. We performed a randomized crossover study of eleven middle-aged men with obesity without regular exercise habits, administered either A-mix (3 g/dose) or a placebo (3 g of dextrin/dose). Thirty minutes after ingestion, each subject subsequently performed workload tests on a cycle ergometer at 40% of peak oxygen consumption for 1 h. Following oral intake of A-mix, the concentration of plasma ketone bodies was significantly increased during exercise. This was accompanied by a significant increase in the area under the concentration-time curve for glucagon. Taken together, these results indicate that pre-exercise ingestion of the A-mix supplement significantly accelerated hepatic ketone body synthesis via stimulation of glucagon secretion during exercise in men with obesity."
