Judul: Diversity and genetic structure of southeast sulawesi  teak populations based on microsat ellite markers
Abstrak: The aim of this research was to study diversity and genetic population structure, dynamical aspect of gene flow through pollens and seeds dispersal and also mating system. This study was carried out at three locations of teak stand populations which indicated human disturbance level using ten markers microsatellite (AGT10, AC44C AC10, AG14, ATC02, AC28, AAG10, and CPIMS). A total of 46 alleles were detected, with six the highest number allele at AAG10 and AG16 loci. The mean value of polymorphic information content (PIC) of the 10 loci ranged from 0.442 to 0.580.

Judul: Genetic structure and variation of five Shorea leprosula natural populations based on microsatellite marker
Abstrak: Shorea leprosula is an economically and ecologically important timber species and one of the most common tropical lowland rain forest tree species in Southeastern Asia. Eleven microsatellites DNA loci were used to investigate the genetic structure and diversity among five natural populations from Sumatera (CS and NS), Peninsular Malaysia (SM) and Borneo (WKa and WKb). Results indicated that expected mean heterozygosity (He) was high (0.721) with values ranging from 0.542 to 0.788, with the highest values found in the populations from west Kalimantan (WKb). Most of the populations showed high and positive fixation indices indicating excess of homozygotes. This implies a high level of inbreeding which may be caused by selfing or/and mating among relatives. A gene diversity analysis showed that 89.9% of the variation was harbored within populations and 11.1% (FST= 0.111) was due to differences among populations. STRUCTURE analysis showed that five natural populations were clustered into two main groups namely: i) Sumatera-Peninsular Malaysia, and ii) Borneo. Mean gene flow (Nm) was high (2.00) indicating extensive gene flow in the past among the natural populations. Three populations (WKb, NS and SM) were identified to be genetically unique and we recommended for further consideration in formulation of genetic conservation strategies.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
