Se purifico hormona luteinizante bovina (bLH) de adenohipófisis congeladas. La extracción se realizó con agua y acetato de amonio-etilnol, seguido de una purificación secuencial por cromatografías en CM-celulosa y DEAE· celulosa, con un rendimiento de 8.

Idiopathic Pulmonary Fibrosis is a chronic lung disease characterized by lung inflammation and progression to fibrosis. Anti-fibrotic efficacy of lutein was studied in mouse model of bleomycin induced pulmonary fibrosis. The mice were orally administrated... see more

Coccomyxa sp. (strain onubensis) is an acidic environment microalga, which was grown under spring outdoor conditions of Huelva province (southwest, Spain). A 6 L pilot tubular photobioreactor was used to determine the influence of the environmental light ... see more

Protection of the fatty acid and lipid components of oocytes that render them susceptible to free radical or other oxidative injury may prevent the damage currently associated with culture. The goal of this study was to establish the influence of several ... see more

As defence against oxidative stress, living systems employ antioxidants that they either produce or take up from the environment. Among these lutein has been shown to be a powerful antioxidant that also functions as a signal molecule. The goal of this stu... see more

Free radicals (FR) are important for a correct development of neonatal organs and tissues. However, newborn and fetus have profoundly impaired antioxidant system. In these subjects, oxidative stress (OS) may be detrimental by activating deleterious cellul... see more

KAROTENOID DARI MAKROALGAE DAN MIKROALGAE: POTENSI KESEHATAN APLIKASI DAN BIOTEKNOLOGI [Carotenoids from Macroalgae and Microalgae: Health Potential, Application and Biotechnology] Helly de Fretes1)*, AB. Susanto2), Budhi Prasetyo1) dan Leenawaty Limantara3) 1) Magister Biologi, Universitas Kristen Satya Wacana, Salatiga 2) Fakultas Perikanan dan Ilmu Kelautan, Universitas Diponegoro, Tembalang, Semarang 3) Ma Chung Research Center for Photosynthetic Pigments, Universitas Ma Chung, Malang   Diterima 13 Desember 2011 / Disetujui 24 Mei 2012 SUMMARY   Algae, both micro and macroalgae, is one of the largest producers of carotenoids. The major composition of carotenoid on algae are ß-carotene, astaxanthin, luthein, zeaxanthin, cryptoxanthin, and fucoxanthin which have important roles for human health. Carotenoids were produced by several microalgae species such as Dunaliella sallina, Haemotococcus pluvialis, Chlorella pyrenoidosa, Spirulina platensis, Nannnochloropsis oculata, and also from some macroalgae species such as Kappaphycus alvarezii, Sargassum sp, and Caulerpa sp. Carotenoids from algae has been proven as a powerful antioxidant and may prevent some degenerative diseases, cardiovascular, and cancer. Carotenoid also has been applied as a natural dye and dietary supplements. Biotechnology has been developed to increase the production of carotenoids from micro- and macroalgae. The large-scale cultivation of microalgae, either in open or closed system are shown to increase carotenoid production. During cultivation, some stress conditions can be specifically manipulated to optimize carotenoid production from microalgae.   Keywords: application, biotechnology, carotenoid, macroalgae, microalgae SUMMARY   Algae, baik mikro maupun makroalgae, merupakan salah satu penghasil karotenoid terbesar. Komposisi karotenoid penting yang dikandung oleh mikroalgae dan makroalgae terdiri dari ß-karoten, astaxantin, lutein, zeaxantin, kriptoxantin, serta fukoxantin.Seluruhnya memiliki peranan bagi kesehatan manusia. Karotenoid-karotenoid tersebut diproduksi oleh beberapa spesies mikroalga yaitu Dunaliella sallina, Haemotococcus pluvialis, Chlorella pyrenoidosa, Anthrospira platensis, serta Nannnochloropsis oculata, dan juga beberapa spesies makroalga seperti Kappaphycus alvarezii, Sargassum sp, dan Caulerpa sp. Karotenoid dari algae telah terbukti sebagai antioksidan yang kuat serta dapat mencegah beberapa penyakit degeneratif, kardiovaskular, dan kanker. Karotenoid juga telah diaplikasikan sebagai pewarna dan suplemen makanan. Bioteknologi telah dikembangkan dalam rangkai peningkatan produksi karotenoid dari mikroalgae dan makroalgae. Selama kultivasi, beberapa kondisi stres dapat dimanipulasi secara khusus untuk mengoptimalkan produksi karotenoid dari mikroalgae.   Kata kunci: aplikasi, bioteknologi, karotenoid, makroalgae, mikroalgae

BACKGROUND: The diagnosis of polycystic ovary syndrome (PCOS) is not an easy procedure, as the signs and symptoms are heterogeneous and of undefined aetiology.AIM: This study is aimed to evaluate serum anti-Mullerian hormone (AMH) level and luteinizing ho... see more

BACKGROUND: Some benign changes of the ovaries like hyper reaction luteinalis sometimes cannot be differentiated from malignant ones without histological examination. In these cases, surgical intervention sometimes cannot be avoided. Hyperreactio luteinal... see more
