Filling a real knowledge gap, this handbook and ready reference is both modern and forward-looking in its emphasis on the "bench to bedside" translational approach to drug development. Clearly structured into three major parts, the book stakes out the boundaries of peptide drug development in the preclinical as well as clinical stages. The first part provides a general background and focuses on the characteristic strengths and weaknesses of peptide drugs. The second section contains five cases studies of peptides from diverse therapeutic fields, and the lessons to be learned from them, while the final part looks at new targets and opportunities, discussing several drug targets and diseases for which peptide drugs are currently being developed.

By covering the full spectrum of topics relevant to peptidic drugs, this timely handbook serves as an introductory reference for both drug developers and biomedical researchers interested in pharmaceutically active peptides, presenting both the advantages and challenges associated with this molecular class. The first part discusses current approaches to developing pharmaceutically active peptides, including case studies of the use of peptidic drugs in cancer and AIDS therapy. The second part surveys strategies for the development and targeting of peptidic drugs. With its integration of biochemical, pharmaceutical and clinical research, this work reveals the full picture of modern peptide drug research in a single volume, making it an invaluable reference for medicinal chemists, biochemists, biotechnologists, and those in the pharmaceutical and biotechnological industries.

Hipertensi merupakan penyakit yang paling sering dijumpai dan merupakan penyebab utama penyakit kardiovaskular di dunia. Hipertensi sebagian besar tanpa gejala tetapi akan merusak organ tubuh diantaranya jantung yang akan mengalami perubahan struktural dan fungsional yaitu LVH (left ventrikel hypertrophy) dan disfungsi diastolik. Disfungsi diastolik saja akan meningkatkan risiko kardiovaskular tidak tergantung pada massa LV dan tekanan darah. Disfungsi diastolik pada hipertensi mungkin terjadi disertai LVH maupun tidak. Beberapa tahun terakhir studi mengenai brain natriuretic peptide (BNP) banyak dilakukan, demikian pula pada disfungsi diastolik sebagai penanda kelainan fungsi ventrikel. Kenaikan kadar BNP mungkin dapat digunakan untuk memperlihatkan proses perubahan fungsi ventrikel sebagai peijalanan penyakit hipertensi. Tujuan penelitian Mengetahui hubungan antara peningkatan kadar BNP dengan derajat disfungsi diastolik pada penderita hipertensi. Hipotesis penelitian dan manfaat penelitian Kenaikan kadar BNP berhubungan dengan derajat disfungsi diastolik pada pasien hipertensi. Pemeriksaan BNP diduga dapat digunakan sebagai alat deteksi dini efek hipertensi pada jantung. Metodologi Penelitian dilakukan pads penderita hipertensi di PINHK selama kurun waktu April std Oktober 2006 (40 pasien, 24 pria, dan 16 wanita). Pasien yang memenuhi }criteria inklusi dan eksklusi dilakukan pemeriksaan ekokardiografi dan diukur EDD, ESD, IVSD,IVSS,massa LV, fraksi ejeksi, rasio EIA, DT, IVRT, rasio e'la',rasioEle', dan doppler vena pulmonal menggunakan alat ekokardiografi dari Vivid -Philips. Pasien dibagi menjadi kelompok dengan fungsi diastolik normal (DDO), disfungsi diastolik tahap I (DDI), psedonormal (DD2) dan restriktif (DD3). Seluruh pasien dilakukan pemeriksaan BNP dengan menggunakan Abbott AxSYM BNP assay pada hari yang sarna dengan ekokardiografi. Uji korelasi dilakukan dengan Pearson test. Hasil Didapatkan kadar BNP masing-masing kelompok tidak berbeda bermakna (DD0=39,77+45,95 pg/ml;DD1=39,35±36,51 pglml;DD2=45,15+_3,65 pg/rnl;p=0,79). Tidak terdapat korelasi kadar BNP dengan rasio E/A (r=0,13;p=0,44) dan indeks massa LV (r=0,005;p=O,97). Terdapat korelasi positif BNP dengan nilai Ele' (r=0,524;p=O,O1). Kesimpulan Tidak terdapat korelasi BNP dengan disfungsi diastolik pada pasien hipertensi asimtomatik. Nilai BNP berkorelasi dengan nilai Ele' yang menunjukkan nilai tekanan pengisian ventrikel kin.

Background Hypertension is the most common disease entity encountered in clinical practice. It is still the main cause of cardiovascular event in the world. Hypertension is mostly seen in the clinic as asympomatic. But during time it may impact heart, as one of target organ, which may shown left ventricle hypertrophy as well as diastolic dusf unction. Even diastolic dysfunction could impact in increasing cardiovascular event in the future. Diastolic dysfunction maybe associated with hypertrophy or it may be precedes hypertrophy. Recently studies regarding brain natriuretic peptide in diastolic dysfunction has been conducted as a marker for ventricle dysfunction. BNP may be use to express the process of ventricle dysfunction in hypertension. Aim of the study To see the correlation of increasing level of BNP with degree of diastolic dysfunction in hypertensive patient. Hypotesis and benefit of the study !increasing level of BNP correlate with degree of diastolic dysfunction in hypertensive patient. Thus BNP may be beneficial as tool for early detection of hypertension impact to heart. Methodology Study was conducted to outpatient with hypertension in PJNHK during April-October 2006 (40 pts, 24 male, 16 female). All patients was done echocardiography exam to see the diastolic dysfunction and ventricular dimension. All patients was classified as normal diastolic function (DDO), diastolic dysfunction grade I (DM), pseudonormal (DD2) and restrictive filling pattern (DD3) accordingly. BNP measurement was done at the same time echo was done using Abbot AxSYM assay.Pearson test was done for correlation test. Result There was no difference among the group for diastolic dysfunction (DDO= 39,77±45,95 pg/ml,DD1=39,35±36,51 pg/ml; DD2=45,15±3, 65 pg/ml;p0, 79). No correlation of BNP with E/A ratio ((r=0,13;p=0,44) and LV mass index (r=0,005;p=0,97). BNP value correlate well with E/e ' ratio representing LV filling pressure ((r=0, 524;p =0, 01). Conclusion BNP level not correlate well with diastolic dysfunction in this group of aymptornatic hypertensive patients. BNP value correlate with E/e' which shown a LV filling pressure.

Protein PD-1 biasanya diekspresikan berlebihan pada pasien kanker dan menghambat sistem imun. Antibodi monoklonal dari PD-1 dapat digunakan untuk menghambat jaras tersebut. Namun, urutan nukelotida dari epitop dengan afinitas yang kuat masih belum diketahui. Oleh karena itu, plasmid yang mengandung epitop kecil dari PD-1 dibuat untuk proses epitope mapping. Tujuan penelitian ini adalah untuk mendapatkan plasmid yang mengandung daerah N-terminal dari gen PD-1. DNA insert sintetik dibuat dari metode PCR dan dipurifikasi. Kedua DNA insert dan plasmid pQE80L didigesti dengan enzim restriksi BamH1 dan HindIII, dipurifikasi dan diligasi. Plasmid tersebut dimasukkan kedalam sel kompeten TOP10 dengan transformasi heat shock. Koloni positif diseleksi menggunakan metode PCR koloni dan verifikasi dengan menggunakan digesti dan sanger sequencing. Produk PCR dari EP1PD1 didapat dengan menggunakan suhu annealing sebesar 57ºC dan berhasil diligasi ke plasmid pQE80L and ditransformasikan. Hasil dari sequencing menunjukan urutan yang sama namun terdapat insersi diawal. Beberapa modifikasi perlu dilakukan untuk mengekspresi protein EP1PD1. Konklusi dari penelitian ini adalah plasmid yang mengandung epitop 1 PD-1 berhasil diperoleh dengan insersi. ......PD-1 protein tends to be overexpressed in cancer patient and inhibits immune system. Monoclonal antibody of PD-1 can be used to inhibit this pathway. However, the sequence of epitope with strong affinity is currently unknown. Thus, plasmid containing small epitope of PD-1 was made for PD-1 epitope mapping process. The objective of this research is to obtain plasmid containing N-terminal region of PD-1 gene. Synthetic insert DNA was made using PCR method and purified. Both insert DNA and pQE80L plasmid were digested using BamH1 and HindIII enzyme, purified and ligated. It was then inserted into TOP10 competent cell using heat shock transformation method. Positive colonies are selected using PCR colony and verified using digestion and Sanger sequencing. PCR product of EP1PD1 are obtained using annealing temperature of 57ºC and able to be ligated to pQE80L plasmid and transformed. Sequencing result shows EP1PD1 result with insertion in the beginning. Modifications are required to express EP1PD1 protein. In conclusion, the plasmid containing Epitope 1 of PD-1 are able to be obtained with insertion.
