"With rapidly rising life expectancies and a general lack of understanding about the aging process, the need to treat geriatric diseases is becoming an ever more significant private and public health issue. In Aging Methods and Protocols, Yvonne and Christopher Barnett and a team of recognized international experts detail key biochemical, analytical, and molecular techniques for the investigation of aging at the cellular, tissue, organ, and whole system levels. These cutting-edge methods address a wide range of research needs, from uncovering the factors associated with cell senescence and death, to exploring alterations in the body's ability both to metabolize xenobiotics, and to defend itself against biomolecular damage. State-of-the-art protocols also measure the morphological, functional, and molecular changes that accumulate within mitochrondria over time, and permit the genetic and functional characteristics of the immune system to be determined. Two important case studies examine the role of dietary restriction on life span extension and the use of transgenic animals in the molecular analysis of aging. Wide ranging and highly practical, Aging Methods and Protocols provides today's molecular gerontologists, pharmacologists, and clinical investigators with a gold-standard collection of readily reproducible techniques for identifying those key cellular and molecular processes that might one day make it possible to regulate the aging process"

"Paparan sinar UV yang berlebihan merupakan salah satu faktor ekstrinsik penyebab terjadinya penuaan dini, yaitu akibat terbentuknya radikal bebas dan Reactive Oxygen Species (ROS). Rubus fraxinifolius Poir. terutama pada bagian daunnya terbukti secara in vitro memiliki sifat antipenuaan dengan cara mencegah aktivitas enzim elastase. Tujuan dari penelitian ini adalah menganalisis kadar total fenol, kadar total flavonoid, aktivitas antioksidan DPPH (1,1-difenil-2-pikrilhidrazil), FRAP (Ferri Reducing Antioxidant Power) dan ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) serta aktivitas penghambatan elastase dari ekstrak (hasil optimasi jenis daun dan optimasi metode ekstraksi) dan fraksi daun Rubus fraxinifolius, selanjutnya fraksi ter-aktif diformulasikan dalam sediaan gel. Penelitian diawali dengan optimasi jenis daun terlebih dahulu dengan cara ekstraksi terhadap daun tua dan daun muda secara Soxhlet, dan dievaluasi aktivitas antioksidan dan aktivitas penghambatan elastase. Selanjutnya dilakukan optimasi metode ekstraksi secara Soxhlet, Microwave Assisted Extraction (MAE) dan Ultrasound Assisted Extraction (UAE) kemudian dievaluasi aktivitas antioksidan dan aktivitas penghambatan elastase. Ekstrak teraktif selanjutnya dilakukan fraksinasi dengan n-heksana, etil asetat, dan aquadest. Fraksi teraktif dilakukan pengujian antioksidan dan aktivitas penghambatan elastase, kemudian diidentifikasi menggunakan LC-MSMS. Berdasarkan hasil optimasi jenis daun, ekstrak daun tua memiliki kinerja yang lebih baik dibandingkan dari daun muda dalam hal aktivitas antioksidan dan aktivitas penghambatan enzim elastase. Sedangkan hasil optimasi metode ekstraksi, UAE memberikan hasil terbaik untuk selanjutnya difraksinasi dan fraksi aquadest memberikan hasil terbaik aktivitas antioksidan dan aktivitas penghambatan enzim elastase. Formulasi gel fraksi aquadest dari metode ekstraksi secara UAE menunjukkan pada formula 1 dengan konsentrasi fraksi daun Rubus 3% memberikan hasil yang lebih baik dan stabil selama masa penyimpanan 12 minggu.

Excessive exposure to UV light is one of the extrinsic factors that causes premature aging, which is due to the formation of free radicals and Reactive Oxygen Species (ROS). Rubus fraxinifolius Poir. especially in the leaves have antiaging in vitro properties by preventing the activity of elastase enzyme. The purpose of this study was to analyze total phenol levels, total flavonoid levels, antioxidant activity of DPPH (1,1-diphenyl-2-pikrilhidrazyl), FRAP (Ferri Reducing Antioxidant Power) and ABTS (2,2'-azino-bis(3- ethylbenzothiazoline-6-sulfonic acid) also elastase inhibitory activity of the extract (from optimizing leaf types and optimizing extraction methods) and Rubus fraxinifolius leaf fractions, then the most active fractions are formulated in Gel preparations. The research begins with optimizing leaf types first, by extraction old leaves and young leaves used Soxhlet method, and evaluated their antioxidant activity and elastase inhibition activity. Furthermore, optimization of extraction methods (Soxhlet, Microwave Assisted Extraction/ MAE and Ultrasound Assisted Extraction/ UAE) was carried out and then evaluated antioxidant activity and elastase inhibitory activity. Active extract then fractionated with n-hexane, ethyl acetate, and aquadest. The most active fraction was tested for antioxidant and elastase inhibitory activity, then identified using LC-MSMS. Based on the optimization of leaf types, old leaf extract has better performance than young leaves in terms of antioxidant activity and elastase enzyme inhibitory activity. While the optimization results of extraction method UAE gave the best results. Fractionation process gave aquadest fraction the best results for antioxidant activity and elastase enzyme inhibitory activity. The gel formulation of the aquadest fraction from the UAE extraction method showed that formula 1 with a concentration of 3% Rubus leaf fraction gave better and more stable results during a storage period of 12 weeks."

"The Handbook of the Psychology of Aging has become the definitive reference source for information on the psychology of adult development and aging. It provides comprehensive reviews of research on biological and social influences on behavior and age-related changes in psychological function. The seventh edition of the Handbook will contain all new material and include an entirely new section devoted to what neuroscience has discovered on cognitive aging. Contains all the main areas of psychological gerontological research in one volume Entire section on neuroscience and aging Begins with a section on theory and methods Edited by one of the father of gerontology (Schaie) and contributors represent top scholars in gerontology"

"It provides a foundation for understanding and reflecting on key demographic and social trends, together with related theoretical and policy frameworks that are important in explaining changes and designing informed responses. With particular reference to countries that have the oldest or largest aged populations, the book presents a synthesis of research on population aging, new analyses of trends and a discussion of the major social policy strategies. Key topics include the new demography of aging, population health, family change, the third age, international policy concepts and strategies, and comparisons of countries."
