Abstract

Tujuan dari penelitian ini adalah memperoleh informasi infeksi dan sifat-sifat biologis virus Newcastle disease (ND) pada ayam ras maupunayam buras. Sejumlah 529 sampel usap kloaka dikoleksi dari pasar-pasar tradisional dan peternakan rakyat di daerah Bogor dan Tangerang. Sebanyak 20 sampel terdeteksi positif melalui real time reverse transcription-polymerase chain reaction (RRT-PCR) sedangkan dengan isolasi virus terdeteksi positif sebanyak 11 sampel. Selanjutnya empat isolat representasi lokasi dipilih untuk karakterisasi patogenisitas dengan metode mean death time (MDT) pada telur ayam berembrio (TAB) specific pathogen free (SPF), dan karakterisasi antigenisitas menggunakan metode haemagglutination inhibition (HI) dan virus netralisasi (VN) untuk melihat keragaman antar isolat virus. Uji MDT memperlihatkan dua isolat(kode isolat II dan XIII) adalah mesogenik, satu isolat (kode isolate VIII) termasuk lentogenik, dan satu isolat (kode isolat TW) bersifat velogenic. Tiga dari empat isolat menunjukkan hubungan antigenik dengan virus ND strain Komarov dan G7 (genotipe 7) tetapi tidak dengan strain referensi Lasota, sementara isolat velogenic (kode TW) yang berasal dari ayam kampung menunjukkan reaksi silang tinggi dengan antiserum terhadap tiga strain referensi di atas. Sampel-sampel yang diambil di lapang baik itu berasal dari pasar dan peternakan rakyat meskipun secara klinis tidak memperlihatkan gejala sakit dapat diisolasi virus ND dengan karakteristik yang beragam.

Abstract

Penelitian ini bertujuan mengetahui respons antibodi dalam serum ayam petelur terhadap ekskretori/sekretori, dan ditantang dengan telur infektif Ascaridia galli (A. galli) Sebanyak 12 ekor ayam dibagi dalam empat kelompok. Kelompok pertama adalah ayam yang tidak diimunisasi dan tidak diinfeksi (kontrol), kelompok kedua adalah ayam yang diimunisasi dengan dosis 260 g ekskretori/sekretori larva A. galli, kelompok ketiga adalah ayam yang diinfeksi dengan dosis 1000 telur infektif A. galli, dan kelompok keempat adalah ayam yang diimunisasi dengan dosis 260 g ekskretori/sekretori dan satu minggu kemudian ditantang dengan dosis 1000 telur infektif A. galli. Respons antibodi pada masing-masing kelompok dianalisis dengan uji enzymelinkedimmunosorbantassay (ELISA) setiap satu minggu selama 10 minggu pascainfeksi. Hasil penelitian menunjukkan bahwa imunisasi dan atau infeksi dapat memicu peningkatan titer antibodi serum secara signifikan (P0,05) selama 10 minggu pascainfeksi. Titer tertinggi adalah 2,631,20 OD (optical density) dicapai pada minggu ke-3 pascainfeksi dan titer terendah adalah 1,510,48 OD pada minggu ke-0. Ekskretori/sekretori dapat memicu respons antibodi serum ayam petelur terhadap A. galli.

Abstract

This study aimed to investigate the mechanism of rice bran oil on altering lipid absorption and blood lipid level in normal rat. Male Sprague Dawley rat age 3 months old, weighted 250–300 g were grouped into three groups: control (aquabidest 1 ml), orlistat (2.16 mg / 200 g body weight), and rice bran oil (1.04 mg γ-oryzanol / 200 g body weight). The intervention was given through oral gavage, daily for 28 days. Indicators observed were growth performance, total cholesterol and serum triglyceride levels, lipid levels in feces, and accumulation of intra-abdominal fat. The results showed that the treatment did not significantly affect body weight gain. Fecal lipid levels of orlistat, rice bran oil and control group respectively were 0.19g; 0.17g and 0.13 g (p<0.05), while the percentage of indigestible lipids for orlistat, control and rice bran oil group were 26%, 17% and 13% respectively (p<0.05). Total cholesterol and serum triglyceride levels in rice bran oil group were significantly lower than controls. Rice bran oil did not significantly affect the percentage of total intra-abdominal fat and the weight of the heart and kidney (p>0.05). The intervention of rice bran oil was shown to reduce blood cholesterol and triglyceride levels in normal mice and did not accumulate intra-abdominal fat. The results suggest that rice bran oil might have an effect on blood lipid regulation but not by preventing lipid absorption.

Abstract

Epidermal growth factor receptor variant III (EGFRvIII) is a mutant of EGFR lacking 267 amino acids (exon-2 through 7) within its extracellular domain, resulting in the formation of a new epitope as a tumor specific target. EGFRvIII is commonly found in GBM, breast, ovarian, prostate, and lung carcinomas. Antibodies or part of antibodies (e.g. single chain variable fragment or scFv) with specific activity against this receptor have been developed. These antibodies are internalized into the cell after receptor binding. Ribonucleases can be cytotoxic due to their inherent ability to degrade RNA, therefore causing cell death via inhibition of protein synthesis. The aim of this research is to construct, clone and express an immunotoxin-based conjugate combining an anti-EGFRvIII scFv with a HPRmut (human pancreatic ribonuclease mutant variant) in Pichia pastoris. The anti-EGFRvIII scFv gene was cloned into yeast expression vector pPICZαA and fused with EGFP gene as a marker. The HPRmut gene was subsequently cloned at the C-terminal of the scFv::EGFP fusion, resulting in the scFv::EGFP::HPR fusion construct. The fusion construct was successfully obtained and nucleotide sequence of plasmid was verified. This construct was used to transform P. pastoris SMD 1168H. The gene fusion was successfully transformed and expressed in P. pastoris with a transformation efficiency of 102 cfu/μg DNA. The transformed yeasts were screened on agar media containing up to 1000 μg/ml zeocin. Yeast transformants showed green fluorescent due to the expression of EGFP gene. The recombinant proteins have been expressed and secreted from P. pastoris as showed by immunoblotting and SDS-PAGE analyses, then purified by affinity chromatography method. The selected yeast transformant produced at least 15.85 mg of purified protein per liter of yeast culture.
