"No one wants to get old or show the signs of age. In fact, for centuries many have searched for, and often promised, the fountain of youth. So what makes The Anti-Aging Zone different?
In this new, breakthrough book. Dr. Sears goes beyond looking at food as simply a source of calories and explains the incredibly powerful biological effects it has on your hormones. From this unique perspective, food is more than a source of sustenance; it becomes the most powerful drug known to man. More important, it is the only drug proven to reverse the aging process. In addition to unraveling the mysteries of your hormones and their role in aging, Dr. Sears reveals the essential dietary information you need to start your own age-reversal journey. Using his simple and easy-to-follow program, you will be able to live longer and live better beginning with your very next meal.
As Dr. Sears explains, the aging process isn't caused as much by the depletion or lack of hormones as we get older, but rather by their impaired ability to communicate with each other. Little-known "super-hormones" called eicosanoids can reestablish the critical communications links between your hormones, which is the key to age reversal. The brilliance of this anti-aging approach is that these exceptionally powerful super-hormones can be altered by the foods you eat, and, in particular, by the Zone Diet.
Your body is a vast, complex biological Internet whose hormonal communication can be orchestrated with great precision by the Zone Diet. Hormones from melatonin to serotonin, from estrogen to testosterone, from cortisol to DHEA, can all be controlled if you are willing to treat food with the same respect as you would any prescription drug. Ultimately, hormonal miscommunication is the underlying cause of many conditions associated with "getting older" such as insomnia, wrinkles, dry and dull skin, waning sex drive, depression, chronic pain, obesity, diabetes, heart disease, and cancer. Using The Anti-Aging Zone as your guide, you can look and feel better that you ever imagined.
Millions of people like you are now facing the hard realities involved with getting older. Dr. Sears separates the hormonal hype from reality and gives you the necessary tools to add years to your life and improve your appearance. The Anti-Aging Zone is your passport to a longer and better life."

"Asiatikosida adalah konstituen utama yang diisolasi dari Centella asiatica (L.) dan merupakan salah satu zat aktif yang banyak digunakan untuk mencegah penuaan kulit. Namun, asiatikosida memiliki masalah ketidakstabilan karena mudah teroksidasi dan terdegradasi. Hal ini dapat mempengaruhi stabilitas asiatikosida dalam sediaan kosmetik. Penelitian ini bertujuan untuk mendapatkan mikroemulsi asiatikosida sebagai sistem pembawa yang dapat meningkatkan stabilitas asiatikosida dan memfasilitasinya sebagai sediaan kosmetik. Pada penelitian ini, optimasi mikroemulsi asiatikosida dilakukan dengan memformulasikan mikroemulsi menggunakan isopropil miristat (sebagai fase minyak) dengan konsentrasi surfaktan (Tween 80) yang berbeda, yaitu F1 = 20%, F2 = 25%, dan F3 = 30%. Mikroemulsi dibuat dengan menggunakan metode titrasi fase. Ketiga formula yang diproduksi dievaluasi dalam hal organoleptik, distribusi ukuran partikel, pH, bobot jenis, viskositas, rheologi dan tegangan permukaan, cycling test, sentrifugasi, uji stabilitas 6 minggu pada 5±3°C dan 30±2°C, serta uji penetapan kadar selama 5 minggu penyimpanan. Mikroemulsi jernih dihasilkan dari F2 dan F3, sedangkan F1 tampak keruh dan terjadi pemisahan fase. Uji penetapan kadar menunjukkan bahwa kadar asiatikosida selama 5 minggu dalam formula F1, F2 dan F3 berturut-turut adalah 65,25 ± 13,73%; 42,62 ± 15,72% dan 68,50 ± 5,94%. Dapat disimpulkan bahwa mikroemulsi yang mengandung asiatikosida yaitu F2 dan F3 memenuhi persyaratan dan stabil secara fisik selama penyimpanan 6 minggu. Namun, belum dapat meningkatkan stabilitas kimia asiatikosida selama penyimpanan 5 minggu.

Asiaticoside is the main constituent isolated from Centella asiatica (L.), and is one of the active substances widely used to prevent skin aging. However, asiaticoside has instability problems because it is easily oxidized and degraded. This can affect the stability of asiaticoside in cosmetic preparations. The aim of this study was to obtain an asiaticoside-containing microemulsion as a carrier system that could increase the stability of asiaticoside and facilitate it as a cosmetic preparation. In this study, optimization of the asiaticoside-contiaining microemulsion was carried out by formulating the microemulsion using isopropyl myristate (as an oil phase) with different surfactant (Tween 80) concentrations, namely F1 = 20%, F2 = 25%, and F3 = 30%. The microemulsion was prepared by using the phase titration method. The three formulations manufactured were evaluated in terms of their organoleptic, particle size distribution, pH, mass density, viscosity, rheology and surface tension. Moreover, a cycling test, centrifugation method, 6-week stability test at 5±3°C and 30±2°C, and drug content assay during 5-week of storage were also conducted. Clear microemulsions were produced from F2 and F3, while F1 looked cloudy and phase separation occurred. The assay results showed that the asiaticoside levels for 5 weeks in F1, F2 and F3 were 65.25 ± 13.73%; 42.62 ± 15.72% and 68.50 ± 5.94%, respectively. It can be concluded that the asiaticoside microemulsions F2 and F3, meet the requirements and were physically stable during 6 weeks of storage. However, it has not been able to increase the chemical stability of asiaticoside during 5 weeks of storage.  "

"Penuaan adalah salah satu faktor resiko signifikan untuk sejumlah penyakit tidak menular degeneratif dan sering bermanifestasi sebagai penyakit kardiovaskular, kognitif dan metabolik. Studi terbaru telah mengidentifikasi peroxisome proliferator-activated receptor γ co-activator α (PGC-1α) sebagai pengatur utama fungsi mitokondria, yang sering dihubungkan dengan teori penuaan. Karena keterlibatannya dalam metabolisme energy, kegagalan energy akibat puasa mungkin dapat merangsang ekspresi PGC-1α, khususnya pada organ yang aktif secara metabolic seperti hati dan jantung. Penelitian ini bertujuan untuk menyelidiki manfaat anti-penuaan dari puasa dengan cara menganalisis ekspresi PGC-1α dalam sel hati kelinci yang dipuasakan. Tiga kelompok kelinci yang telah (1) diberi makan secara ad libitum; (2) dipuasakan selama 16 jam (puasa intermiten); (3) dipuasakan selama 40 jam (puasa berkepanjangan). RNA diekstraksi dari jaringan hati kelinci dari masing-masing kelompok. qRT-PCR dilakukan untuk mencari ekspresi relative gen PGC-1α sebagai biomarker anti-penuaan. Terdapat peningkatan signifikan ekspresi relative PGC-1α pada hati kelinci yang dipuasakan dibanding kelinci yang diberi makan ad libitum. Penelitian lebih lanjut yang melibatkan pemantauan kelinci diperlukan untuk mengamati sifat anti-penuaan pada kelinci yang telah dipuasakan dibandingkan kontrol untuk menyimpulkan sebesar apa efek puasa terhadap penundaan penuaan.

Ageing is a significant risk factor for various of non-communicable diseases, often manifesting as cardiovascular, cognitive and metabolic degenerative diseases. Recent studies have identified peroxisome proliferator-activated receptor γ co-activator α (PGC-1α) as a major regulator of mitochondrial function, a common feature in the many theories of ageing. Due to its involvement in energy metabolism, it is theorised that energetic failures due to fasting may be able to stimulate the expression of PGC-1α. This research aims to investigate anti-ageing benefits of fasting by analysing the expression of PGC-1α in liver cells of fasted rabbits compared to rabbits fed ad libitum. Three groups of rabbits were (1) fed ad libitum; (2) subjected to intermittent (16-hour) fast; and (3) subjected to prolonged (40-hour) fast. RNA was extracted from the liver tissues of the rabbits. The relative expression of PGC-1α mRNA as a biomarker of anti-ageing was analysed by qRT-PCR. There was a significant increase in relative expression of PGC-1α in fasted rabbits than those fed ad libitum. Further research involving the monitoring of the rabbits is needed to observe for anti-ageing traits in fasted rabbits as opposed to the control to conclude the extent of the effect of fasting on delaying ageing."
