"ABSTRAK Kanker endometrium merupakan keganasan ginekologi tersering keempat pada wanita. Di seluruh dunia, setiap tahun 142,000 wanita terdiagnosis kanker endometrium dan angka mortalitas sekitar 42,000. Kanker endometrium dibagi menjadi 2 tipe yaitu tipe 1 dan tipe 2 berdasarkan histologi dan karakteristik molecular. Kanker endometrium sekitar 80%-90% adalah tipe 1 yaitu adenokarsinoma endometrioid. Tipe I berhubungan dengan estrogen berlebih, faktor-faktor risiko antara lain obesitas, diabetes mellitus, menopause lambat dan nulliparitas. Insiden tipe 2 sekitar 10-20%, angka mortalitas lebih tinggi pada tipe ini. Faktor risiko pada tipe 2 tidak diketahui dengan pasti, dan tidak bergantung pada estrogen. Kanker endometrium tipe 2 memiliki angka kesintasan yang lebih buruk dibandingkan tipe 1.

Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan dan faktor risiko yaitu obesitas, diabetes mellitus tipe 2 dan status menopause pada kanker endometrium tipe 1 dan tipe II.

Metode: Penelitian desain potong lintang di RSUPN Dr. Cipto Mangunkusumo, pasien yang terdiagnosa kanker endometrium dengan hasil histologi dan ditatalaksana selama juli 2014-desember 2016. Data pasien obesitas, diabetes mellitus tipe 2 dan status menopause dicatat dan dianalisa.

Hasil: Didapatkan total 255 subjek penelitian yang memenuhi kriteria inklusi. Pada kanker endometrium tipe 1 didapatkan Indeks massa tubuh (IMT) overweight yaitu 25,09 kg/m², sedangkan tipe 2 didapatkan berat badan ideal. Faktor risiko diabetes mellitus tipe 2 pada kedua tipe kanker tidak signifikan bermakna, pada analisis multivariat didapatkan tipe 2 lebih banyak didapatkan pada status menopause yang lebih awal.

Kesimpulan: Profil faktor risiko antara tipe 1 dan tipe 2 kanker endometrium hampir serupa pada penelitian ini, dikarenakan karakteristik pasien dan jalur etiologi yang bervariasi. Kanker endometrium tipe 2 lebih banyak terjadi pada usia menopause lebih awal.

Composite materials have evolved into versatile materials that are in high demand in various applications, especially in the defence and military fields. Glass Fiber Reinforced Polymer or GFRP, is one of the most commonly used types of composite materials in the field of composite materials manufacturing. Materials such as GFRP offer great potential in this regard, providing effective protection at a lighter weight compared to traditional materials such as steel. The focus of this research is the use of Finite Element Method simulations for ballistics tests to assess the performance of glass fibre and epoxy matrix composite materials against Type I 38 Special Round Nose bullets with a velocity of 274 m/s and Type II 9 mm Full Metal Jacketed bullets with a velocity of 334 m/s, in accordance with National Institute of Justice standards. The results of this simulation will produce a visual representation in three-dimensional form using Finite Element Analysis software. Based on the results of the simulation, 48 layers of fiberglass/epoxy can absorb the kinetic energy of a Special RN bullet amounting to 165.0 Joules and transmit kinetic energy of 7.8 Joules. 80 layers of fiberglass/epoxy can absorb the kinetic energy of a 9mm FMJ bullet amounting to 216.7 Joules and transmit kinetic energy of 23.7 Joules. The damage occurring to the fiberglass/epoxy is brittle fracture. The deformation observed in the bullets in both simulations shows that the front part of the bullets undergoes deformation into a conical shape."

"Human Immunodeficiency Virus type-I (HIV-1) merupakan penyebab sindroma penurunan sistem imun tubuh yang disebut dengan Acquired Immunodeficiency Syndrome (AIDS). Infeksi HIV-I di dunia dan Indonesia cenderung meningkat. Pemeriksaan yang cepat dan spesifik diperlukan untuk mencegah penyebaran infeksi HIV-I. Berbagai teknik telah dikembangkan untuk deteksi infeksi HIV-I. Pada penelitian ini dikembangkan pemeriksaan RT-PCR HIV-1 Mikrobiologi FKUI (in-house RT-PCR) untuk mendapatkan uji alternatif deteksi HIV-1. Sebanyak 46 plasma dan serum kelompok berperilaku risiko tinggi yang berkunjung ke klinik VCT . RSUP Sanglah Denpasar, telah diperiksa dalam penelitian ini. Serum diperiksa dengan 3 kit rapid test yang berbeda yaitu DetermineTM HIV-1/2 (Abbott), ImmunoCombR HIV 1 & 2 BiSpot (Organics), dan SerodieR HIV-1/2 (Fujirebio Inc.). Plasma diuji dengan pemeriksaan RTPCR generasi I menggunakan primer spesifik terhadap daerah gag dan RT-PCR generasi 2 menggunakan primer spesifik terhadap daerah protease dari genom HIV-1. Hasil rapid test menunjukkan dari 46 sampel, sebanyak 26 serum (56,5%) reaktif dan 20 serum (43,5%) non-reaktif. Tingkat sensitivitas, spesifisitas, nilai duga positif, dan nilai duga negatif RT-PCR generasi 1 secara berturut-turut adalah 80,8%, 95%, 95,5%, dan 79,2%, sedangkan rasio kemungkinan positif dan negatif adalah 16,2, dan 0,2. Pemeriksaan RTPCR generasi 2 menunjukkan tingkat sensitivitas 65,4%, spesifisitas 90%, nilai duga positif 89,5%, nilai duga negatif 66,7%, rasio kemungkinan positif 6,5, dan rasio kemungkinan negatif 0,4. Teknik RT-PCR yang menggunakan primer tersebut dapat mendeteksi HIV pada semua stadium klinis WHO pada kelompok ini. Sensitivitas dan spesifisitas RT-PCR generasi 1 lebih baik daripada RT-PCR generasi 2, tetapi, masih lebih rendah daripada baku emas, Secara keseluruhan, RT-PCR pada penelitian ini belum dapat direkomendasikan sebagai uji altematif baik uji skrining maupun uji konfirmasi dalam mendeteksi infeksi HIV-1.

Human Immunodeficiency Virus type 1 (HIV-1) can cause decrease of immune response which is called Acquired Immunodeficiency Syndrome (AIDS). HIV-l infection in the world and Indonesia tends to increase. Many techniques were developed to detect HIV-1 infection. A specific and rapid diagnosis is needed to prevent transmission of HIV-1 infection. In this study, we performed RT-PCR HIV-1 Microbiology FKUI (in-house RT-PCR) as an alternative test to detect HIV-1. Forty six plasmas and serums from high risk behavior group who visited VCT Clinic Sanglah General Hospital, Denpasar were used in this study. Serums were tested with 3 different rapid test kits i.e. Determine ° IIIV-112 (Abbott), immunoComb HIV I & 2 BiSpot (Orgenics), and Serodia ' HIV-112 (Fujirebio Inc.). Plasmas were tested with I generation RT-PCR which used specific primers to gag region in HIV-1 genome and specific primers to protease region in IIIV-1 genome for 2nd generation RT-PCR. Results of rapid test demonstrated 26 serums (56.5%) were reactive and 20 serums (43.5%) were non-reactive. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 1st generation RT-PCR was 80.8%, 95%, 95.5%, 79.2%, whereas positive likelihood ratio (LR +) and negative likelihood ratio (LR -) was 16.2, and 0.2, respectively. The 2"d generation RT-PCR showed sensitivity, specificity, PPV, NPV, LR (+), and LR (-) was 65.4%, 90%, 89.5%, 66.7%, 6.5, and 0.4, respectively. These in-house RT-PCR could detect HIV-1 in all WHO clinical staging in this group. This study showed that lsi generation RT-PCR gives better results than 2"d generation RT-PCR. But still inferior than rapid test to detect HIV-1 infection. Overall, RT-PCR in this study has not been recommended yet as an alternative test to detect HIV-I infection."

"Latar belakang: Celah bibir dan palatum atau cleft lip and palate (CLP) merupakan kelainan kongenital multifaktorial yang mengakibatkan pasien memiliki defek pada jaringan lunak dan keras di bagian bibir dan palatum. Pasien celah bibir dan palatum umumnya menderita gangguan estetik dan fungsi stomatognatik. Sehingga, untuk mengembalikan fungsinya maka harus dilakukan perawatan rekonstruksi tulang alveolar. Baku emas dalam perawataan ini ialah menggunakan autologous bone grafting. Namun, perawatan ini masih memiliki kekurangan sehingga dikembangkan perawatan yang baru dengan teknik rekayasa jaringan dengan sel punca mesenkim. Salah satu sumber sel punca mesenkim yaitu berasal dari jaringan pulpa gigi yaitu sel punca pulpa gigi permanen atau dental pulp stem cells (DPSCs) dan sel punca pulpa gigi sulung atau stem cells from human deciduous teeth (SHED). Kemampuan osteogenik dari sel punca merupakan salah satu faktor pertimbangan untuk pemakaian sel dalam rekayasa jaringan rekonstruksi tulang. Sementara kemampuan osteogenik dari SHED dan DPSCs CLP belum diketahui.Tujuan: Mengetahui potensi kemampuan dan perbandingan potensi osteogenik dari sel punca gigi permanen dan sulung pasien celah bibir dan palatum dengan melihat ekspresi gen Alkaline phosphatase (ALP) dan Collagen Type I Alpha 1 (COL1A1).Metode: Sampel RNA yang diperoleh dari ekstraksi RNA sel jaringan pulpa gigi sulung dan permanen pasien celah bibir dan palatum diuji dengan Real-Time Polymerase Chain Reaction (RT-PCR) menggunakan primers Alkaline Phosphatase (ALP), Collagen Type-I (COL1A1) dan Glyceraldehyde 3-Phosphate Dehydrogenase (GAPDH) sebagai housekeeping gene.

Background: Cleft lip and palate (CLP) is a multifactorial congenital disorder that results in patients having soft and hard tissue defects in the lips and palate. Patients with cleft lip and palate commonly suffer from aesthetic and stomatognathic function disorders. Therefore, to restore its function, alveolar bone reconstruction treatment must be done. The gold standard in this treatment is to perform autologous bone grafting. However, as autologous bone grafting still has associated shortcomings, new treatments using tissue engineering techniques with mesenchymal stem cells are being developed. One of the mesenchymal stem cells sources that can be used is derived from dental pulp tissue, namely permanent dental pulp stem cells (DPSCs) and primary dental pulp stem cells or stem cells from human deciduous teeth (SHED). Osteogenic ability of the stem cells is one of the factors considered for the use of cells in tissue engineering bone reconstruction. Osteogenic ability of SHED and DPSCs hasn’t been fully explored.

Objective: To determine the potential ability and to compare osteogenic potential of DPSCs and SHED from cleft lip and palate patients by looking at the expression of the Alkaline Phosphatase (ALP) and Collagen Type I Alpha 1 (COL1A1) genes.

Methods: RNA samples obtained from RNA cells extraction in deciduous and permanent dental pulp tissue of patients with cleft lip and palate were tested with Real-Time Polymerase Chain Reaction (RT-PCR) using Alkaline Phosphatase (ALP) primers, Collagen Type I Alpha 1 (COL1A1) primers and Glyceraldehyde 3-Phosphate Dehydrogenase (GAPDH) primers as housekeeping gene.

Results: The relative expression of ALP genes in SHED from CLP patients decreased compared to DPSCs from patients with CLP. As for the expression of the COL1A1 gene, there was no difference in expression between SHED from patients with cleft lip and palate and DPSCs in patients with cleft lip and palate.

Conclusion: SHED and DPSCs CLP has osteogenic abilities."
