Abstract

Intracellular signal transduction occurs through cascades of reactions involving dozens of proteins that transmit signalsfrom the cell surface, through a crowded cellular environment filled with organelles and a filamentous cytoskeleton, to specifictarget. For most characterized signal transduction pathway, the initial signaling event and the end point are well known. In order tofully understand intracellular signal transduction, it is essential to know the intermediate signaling molecules and to understandhow information flows from one to the next. The cytoskeleton , an interconnected assembly of actin (microfilament), intermediatefilament and microtubule networks that extend throughout the entire cell, is involved in intracellular signal transduction.Individual proteins of the cytoskeleton might participate directly in signal transduction by linking two or more signaling proteinand might also provide a macromolecular scaffold, which spatially organizes components of a signal transduction cascade.Diabetes mellitus is an increasingly common disease. Absolute or relative deficiencies of insulin are common in this disease.Insulin has been suggested to play a key regulatory role in the functional organization of actin filaments. The microtubules are alsothe targets of insulin. A chronic insulin deficiency may could lead to impairment in the organization of the cytoskeleton. Thiscould entail a compromised or slower action of some activated enzymes in cells, affect to intracellular signal transduction.

Abstract

 Anemia merupakan faktor prognostik independen untuk pertahanan hidup pasien kanker. Penurunan kapasitas oksigen pada darah dapat menyebabkan terjadinya kondisi hipoksia pada jaringan kanker . Hipoksia pada jaringan kanker dapat mengaktivasi faktor transkripsi hypoxia-inducible factor-1α (HIF-1α) yang kemudian akan mentranskripsi banyak gen lain yang terlibat dalam invasi sel, angiogenesis, metabolisme anaerobik dan siklus sel, seperti gen eritropoietin (Epo) dan vascular endothelial growth  factor  (VEGF). Penelitian  ini menggunakan sampel berupa 120 slide peraparat  jaringan kanker payudara (60 anemi dan 60 non anemi) dengan melakukan pewarnaan secara  imunofluoresen double staining untuk protein HIF1α dengan VEGF dan Epo dengan EpoR. Sampel dibagi menjadi 2 kelompok, yaitu anemi (Hb 5,5-10,7) dan non anemi (Hb 11-14,9). Hasil imunofluoresen di analisis dengan menggunakan Confocal Laser Scanning Microscope untuk mengetahui ekspresi protein target. Hasil dari penelitian menunjukkan bahwa tidak ada perbedaan yang signifikan pada ekspresi   HIF1α pada jaringan kanker penderita kanker payudara yang   anemi dan   non anemi namun sebaliknya ada perbedaan ekspresi VEGF yang signifikan (p=0,013) antara pasien anemi (754,4±316) dan non anemi (555,1±276,9). Pada kelompok sampel anemi dan non anemi ada hubungan negatif antara Hb dan HIF1α   (p=0,000; r=-0,522) dan hubungan positif  antara HIF1α dengan EPO (p=0,000; r= 0,697), antara HIF1α dengan VEGF (p=0,000; r=0,644), antara Epo dan VEGF (p=0,001; r=0,433). Pada pasien kanker anemi dan non anemi telah terjadi kondisi hipoksia pada lingkungan tumornya sehingga menyebabkan ekspresi HIF1α tidak berbeda signifikan namun hubungan HIF1α dengan EPO dan VEGF sangat kuat.  Kata Kunci: Anemi, epo, HIF1α, hipoksia, VEGF

Abstract

ABSTRACT Death  caused  by  cardiovascular  and  cerebrovascular diseases  are  still  the  highest.  Atherosclerosis  due  to hypercholesterolemia is a predispositioning factor of both diseases. Curcumin has an antioxidant character that can inhibit lipid peroxidase to atherogenesis process. The aim of this study was to observe the effect of curcumin in decreasing total cholesterol level, LDL-cholesterol, the number of  F2-isoprostan and foam cell of aorta’s wall of white rats strain wistar after giving atherogenic diet for 10 weeks. There were 6 groups in this study (n=24): atherogenic diet group (group I as positive control), atherogenic diet group + curcumin 50 mg/kg b.w. per day (group II), atherogenic diet group + curcumin 100 mg/kg b.w. per day (group III), atherogenic diet group + curcumin 200 mg/kg b.w. per day (group IV), atherogenic diet group + curcumin 400 mg/kg b.w. per day (group V), normal diet group (group VI as negative control). After 10th, the level of total cholesterol and LDL-cholesterol were measured by spectrofotometri. Staining F2-isoprostan was done with Avidin Biotin Complex imunohystochemistry method, and staining foam cell with HE-oil Red O. The number of  F2-isoprostan and foam cells were counting semi quantitatively using  light microscope. The highest total cholesterol level was found in group I (275,15 ± 10,01; Mean ± SD), the highest LDL-cholesterol level was found in group I (158,15 ± 12,19). Statistically total cholesterol level and LDL-cholesterol level in group I were significantly higher (p ≤ 0,05) than other

Abstract

The separation of X and Y spermatozoa can be conducted by using Percoll Gradient Density Centrifugation(SGDP) method. It is, easy, valid, cheap and applicable method for developing made-insemination. Although it  has often been applied in sexing the spermatozoa, it was reported  that the method had often caused damages on the spermatozoa membranes and resulted in decreasing of the spermatozoa quality. The damages of spermatozoa after SGDP  process were specifically caused by (I) the loss of seminalplasma, (II) the increase of free radicals, and (III) the collision or friction among the spermatozoa. Among the three causal factors above, the third or the physical factor is claimed to be the most important one. It was assumed that the first and the second factors can be overcome if the third one is avoided. The spermatozoa membranes consist of lipids, protein, carbohydrate, and some substances at a low rate. Thegeneral objectives of this research was to identify the influence of the phospholipids PC (Phosphatidylcholin)to spermatozoa in order to avoid the damages of the spermatozoa in the process of SGDP.

Abstract

Latar Belakang. Lupus Eritematosus Sistemik (LES) merupakan penyakit autoimun yang semakin sering dijumpai dengan angka kematian tinggi. Etiopatogenesis penyakit ini belum begitu jelas, meskipun telah ditunjukkan adanya abnormalitas berbagai sel-sel imun termasuk hiper-reaktivitas sel T, sel B, sel dendrit; dan menurunnya fungsi sel T regulator (Treg). Vitamin D memiliki peran dalam pengaturan sistem imun. Penelitian pada ras Kaukasia menunjukkan bahwa kadar vitamin D yang rendah berkaitan dengan timbulnya penyakit autoimun termasuk LES. Peran vitamin D pada sistem imun pasien LES masih banyak kontroversi. Penelitian ini bertujuan untuk mengetahui hubungan kadar vitamin D dengan jumlah sel Treg.Metoda Penelitian. Penelitian ini adalah penelitian kasus-kontrol yang membandingkan jumlah sel Treg pada pasien LES dan kontrol sehat dengan melihat status vitamin D-nya. Kadar vitamin D pasien LES diukur dengan metoda ELISA, jumlah sel Treg (CD4+,CD25+,FoxP3+) ditentukan dengan metoda flowcytometri.Hasil. Kadar vitamin D pada pasien LES lebih rendah daripada kontrol sehat (p=0,000) dan didapatkan korelasi negatif antara status vitamin D dengan persentase sel Treg (koefisien korelasi -0,358 dan p=0,006). Hal ini mungkin merupakan umpan balik positif untuk menanggulangi hiperreaktifitas dari sel T dan sel B.Kesimpulan. Status vitamin D berkorelasi negatif dengan persentase sel Treg.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh terapi suplementasi fitosterol pada profil lemak, kadar apolipoprotein B-48, dan mengetahui jumlah sel busa pada tikus pasca diet atherogenik. Penelitian ini dilakukan menggunakan tikus wistar (34 ekor), umur 6-8 minggu, berat 100-160 g, diperlakukan diet atherogenik selama 8 minggu, dilanjutkan dengan diet standar (n=5), diet standar dengan suplementasi tablet fitosterol 0,1% (n=5), 1% (n=6), dan 2% (n=6) dalam total makanan selama 6 minggu. Tikus diet standar 14 minggu sebagai kontrol negatif (n=5) dan tikus diet atherogenik 14 minggu sebagai kontrol positif (n=6). Profil lemak (Kolesterol Total, Trigliserida dan HDL-Kolesterol) dianalisis dengan kit (Diasys), kadar LDL-kolesterol dihitung dengan rumus friedwall sedangkan kadar non HDL-kolesterol dihitung dengan mengurangi kadar kolesterol total dengan kadar HDL-Kolesterol. Kadar Apo-B-48 dianalisis dengan elektroforesis, elektroelusi, dialisa dan spektrofotometri diuret atau laury. Perhitungan jumlah sel busa aorta dilakukan secara manual pada 20 lapangan pandang pembesaran 1000X setelah pewarnaan dengan Oil Red O dan Hematoxilin-Eosin (HE) dengan 3 kali pengulangan. Hasil suplementasi fitosterol dosis 0,1% memiliki rentang 40-50 mg/kgBB/hari, 421-521 mg/kgBB/hari pada dosis 1% dan 937-1250 mg/kgBB/hari pada dosis 2%. Perbedaan signifikan didapatkan pada kadar kolesterol total, LDL-kolesterol, dan non HDL-kolesterol antara kontrol dengan kelompok suplementasi. Kadar HDL-Kolesterol secara signifikan lebih rendah sedangkan kadar ApoB-48 tidak dapat dikuantifikasi akibat berbagai sebab. Penghitungan sel busa pun berbeda nyata antara kontrol dengan suplementasi. Beradsarkan penelitian ini diketahui bahwa suplementasi fitosterol dalam diet memiliki efek terapetik pada profil lemak (kolesterol total, LDL-kolesterol, dan non HDL kolesterol) sehingga mampu mengurangi jumlah sel busa aorta tikus pasca diet atherogenik. Kata kunci: apolipoprotein B, fitosterol, hiperlipidemia, hitung sel busa, profil lemak.

Abstract

Background: Fatigue is one symptom of Systemic Lupus Erythematosus (SLE), which has an important effect on the quality of life. Fatigue Severity Scale (FSS)is one parameter fatigue symptom in SLE. The purpose of this study was to determine the validity and reliabilitybetween FSS with duration of ilness and disease activity of SLE patients in Indonesia.Methods: FSS performed on 40 patients with SLE. FSS original English version has been converted-translated into Indonesian version by a team of RheumatologyImmunology Medical Faculty of Brawijaya University. Reliability determined by Cronbach’s Alpha values (>0.6). Validity was determined by the value of Corrected Item-Total Correlation which each item was a valid question if below value of Cronbach’s Alpha.Results: The reliability value was determined by Cronbach’s Alpha values (>0.6) in which the SLE patients in this study had a Cronbach’s Alpha value of 0.946. Value of Corrected Item-Total Correlation overall under Cronbach’s Alpha value (range = 0.684-0.859) which indicates that each item was a valid question. There were correlation between the FSS Indonesian version with disease duration (p = 0.000) as well as the value of r = 0.581, with SLEDAI (p = 0.000) with a value of r = 0.833. Conclusion: FSS in Indonesian version has a good reliability and validity and can be used by clinicians andother researchers to assess the condition of fatigue in SLE patients in Indonesia.Keywords: validity, reliability, fatigue, fatigue severity scale, systemic lupus erythematosus
