Judul: Analisis morfologi perinereis nuntia (Savigny 1818) spesies kompleks
Abstrak: Perinereis nuntia terdistribusi secara luas hampir di seluruh dunia. Perinereis nuntia dikenal dengan kompleks spesies dengan status taksonomi yang bersifat problematik karena penentuan tingkatan taksonomi berdasarkan morfologi harus memeperhatikan homologi dan konvergensi. Penelitian ini bertujuan untuk mempelajari morfologi cacing P. nuntia dengan analisis morfometrika, sebagai langkah pertama untuk menjelaskan taksonominya. Sampel berasal dari Pulau Pari bagian Selatan dan Timur (Kepulauan Seribu), Pulau Labengki (Sulawesi Tenggara), Sungai Huwei, Shang Shan, Shimen, Daane serta Juoshuei (Taiwan). Data yang diambil adalah data kuantitatif yang berasal dari paragnath, setiger, pigmentasi tubuh, tentakular sirrus, dan antena. Individu mengelompok berdasarkan beberapa perbedaan sifat morfologi ke dalam tiga populasi yang terpisah, yang kongruen dengan letak geografisnya.

Judul: Karakterisasi Morfogenetik Nudibranch dari Beberapa Populasi di Indonesia.
Abstrak: Nudibranch memiliki keanekaragaman spesies yang tinggi dengan karakter morfologi yang kompleks dan menantang untuk diidentifikasi ke dalam tingkat spesies. Penelitian ini bertujuan untuk mengetahui spesies nudibranch dengan menggunakan morfologi dan karakteristik molekuler. Rekonstruksi pohon filogenetik menggunakan metode Neighbor-joining dengan model parameter Kimura-2 dan 1000 nilai bootstrap. Jarak genetik within and between spesies juga diamati. Sebanyak 51 sampel jaringan dan 18 spesimen dikumpulkan dari populasi yang berbeda di Indonesia. Berdasarkan 18 spesimen yang dikumpulkan, total lima spesies diidentifikasi berdasarkan karakter morfologi (Chromodoris magnifica, Phyllidia elegans, Phyllidia varicosa, Phyllidia coelestis, Phyllidiella pustulosa). Hasil barcode DNA menggunakan gen Cytochrome Oxidase I (COI) menunjukkan 18 spesies dari 51 sampel dianalisis. Rekonstruksi pohon filogenetik tersebut menunjukkan 18 clade yang termasuk dalam lima famili termasuk tiga spesies kelompok Phyllidiella (Phyllidiella pustulosa, Phyllidiella nigra, Phyllidiella picta), tiga spesies kelompok Phyllidia (Phyllidia elegans, Phyllidia coelestis, Phyllidia varicosa), empat spesies kelompok Chromodoris (Chromodoris magnifica, Chromodoris annae, Chromodoris quadricolor, Chromodoris striatella), dan masing-masing spesies di kelompok Goniobranchus (Goniobranchus geometricus), Elysia (Elysia cf marginata), Plakobranchus (Plakobranchus papua), Glossodoris (Glossodoris rufomarginata), Nembrotha (Nembrotha cristata), Mexichromis (Mexichromis multituberculata), Dorisprismatica (Dorisprismatica atromar), dan Tritonidae (Tritonia sp 2). Studi ini menunjukkan bahwa barcode DNA dapat digunakan untuk mengidentifikasi nudibranch sampai tingkat spesies, dan mempercepat eksplorasi spesies yang akan menjadi sumber informasi dalam mengelola sumber daya dan menjaga stabilitas ekosistem.

Abstrak: Exercise requires more energy (ATP) than normal activities. Oxygen consumption increases, while lung capacity is limited. It causes anaerobic respiration which produces lactic acid that reduces exercise performance. The purpose of this study was to assess the effects of short-term and long-term drinking of oxygenated water on the exercise performance and oxygen saturation (SpO2), lipid profile (cholesterol, triglycerides, LDL, and HDL) and blood glucose, as well as an influence on liver (AST/ALT). This study included (1) ethical clearance submission, (2) selection of potential respondents, (3) socialization and informed consent, (4) short-term experiment, (5) long-term trials, and (6) data processing. Recruitment of respondents was based on inclusion and exclusion criteria and medical check up. In the socialization, the right way of drinking samples was introduced. In the short-term and after long term experiments, twelve male student volunteers drank oxygenated water (50, 80 and 130 ppm) and normal water, 15 minutes before treadmill (10 Kmh) in Somatokinetika Laboratory of Jakarta State University. SpO2 was measured before and after treadmill, and 0, 5, 10, 15 minutes after drinking. In the long-term, seventeen male student volunteers drank oxygenated water (100 ppm) for 21 days and lipid profile, blood glucose, and AST/ALT were analyzed. Before and after intervention, blood plasma was used to measure the parameters in the Laboratory Clinic of dr Katili. Cholesterol, triglycerides, and blood glucose analysis used enzymatic colorymetry method, while HDL analysis used enzymatic colorymetry and precipitation method. LDL was calculated by Friedewald equation and AST/ALT analysis used kinetic method. Oxygenated water had no effect on SpO2 and exercise performance. Interestingly the average of VO2 max and time to fatigue of those drank oxygenated water were higher than those drank normal water. VO2 max (mL/Kg/menit) increased from 45.87 (normal water) to48.89 (50 ppm), 48.03 (80 ppm), 47.40 (130 ppm), and 48.76 (long-term). Time to fatigue was be reached 10.34 minutes (normal water), 11.18 minutes (50 ppm), 11.27 menit (80 ppm), 130 ppm (10.93 minutes) and 11.60 minutes (long-term). Long-term effects also showed the improvements of cholesterol (168.12 to 114.53 mg/dL), LDL (103.94 to 54.41 mg/dL) and the ratio of cholesterol : HDL, however they were also influenced by diet and intensity of activity. HDL, triglycerides, and blood glucose was not affected by oxygenated water and had no harmful effect on the liver.
