Research ArticleOpen accessEvery word in the titleMicroscopic Study of the Lungs of Sprague-Dawley Rats from Various Ages of Postnatal and Aging PeriodsRia Margiana, Isabella Kurnia Liem, Jeanne Adiwinata PawitanPhysiological changes in postnatal and aging lung are associated with a variety of microscopic changes in the lung, especially the alveolar lung tissue, both in the interstitial and epithelial component. Interstitial tissue of the lung will increase in thickness that is supposed to be due to changes in fiber composition, particularly collagen. However, the exact changes are still under debate … …OnLine Journal of Biological Sciences, Vol. 15, Issue 2 · 13 Jun 2015 · 7,312 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigating Effects of Application of Silica Fume to Reduce Asphalt Oxidative AgingNader Abutalib, Elham H. Fini, Sassan Aflaki, Taher M. Abu-LebdehThis paper investigates the feasibility of using silica fume to enhance the rheological properties of asphalt binder. It has been widely reported that asphalt binder oxidation is one of the phenomena that reduces the service life of asphalt pavement by negatively impacting its rheological properties. This in turn can lead to a more brittle pavement which is more prone to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 8,485 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePRODUCTION OF CROSS-REACTIVE AUTOANTIBODY BINDING TO BOVINE SERUM ALBUMIN IN THE D-GALACTOSE-INDUCED AGING MOUSE MODELJi-Hun Park, Tae-Saeng ChoiThe D-galactose (D-gal)-induced animal model, generated by repeated subcutaneous D-gal injections over approximately 6 weeks, has been frequently used for diabetes and aging research. However, little research has investigated the direct correlation between D-gal and autoantibody formation despite several reports on diabetes-and aging-related autoantibodies. The purpose of this study was to determine whether repetitive injection of D-gal can induce autoantibody … …American Journal of Immunology, Vol. 10, Issue 1 · 13 Jan 2014 · 7,039 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCritical Aging Segments of Power Transmission LineH. H. Goh, N. E. Chin, Q. S. Chua et al.Nowadays, blackouts or sags of a conductor are threatening the safety and stable run of the power transmission lines. These phenomena happen due to the environmental conditions which change over the time, such as aging or temperature variations, precipitation and hotspots of power transmission lines as a result of extreme weather conditions. A precipitation condition result loses of heat from … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 9 Dec 2013 · 9,264 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHormetic Interventions in AgingSuresh I.S. RattanSingle or multiple exposure to low doses of potentially harmful agents can have a variety of anti-aging and longevity-extending hormetic effects. These hormetic stressors include irradiation, physical activity, food limitation, heat, hypergravity, dietary components and reactive oxygen species. Molecular mechanisms facilitating the hormetic effects are being elucidated and comprise a cascade of stress response and maintenance and repair pathways. Although … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,831 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLife Extension by Anti-Aging Drugs: Hormetic Explanation?A.M. VaisermanA number of chemicals including antioxidants, vitamins and hormones are widely advertised as anti-aging drugs (geroprotectors). It is usually believed that life-extending capacity of geroprotectors may be attributed to their specific anti-aging mechanisms, even without solid scientific evidence. The analysis of the survival data gathered by both anti-aging and hormetic interventions demonstrates that many essential similarities exist between them. The … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 8,162 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHormetic Triggers for Intervention in Aging, Disease and TraumaJoan Smith SonnebornHormesis refers to the ability of a chemical or physical agent to condition the physiological state of an organism to tolerate stress with low doses of otherwise harmful agents. Evolutionary evidence shows that the survival and longevity of species hinge on their optimal ability to resist stress challenge. Hormesis is a potent strategy to stimulate latent repair processes to tolerate … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,895 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleENHANCING ASPHALT RHEOLOGICAL BEHAVIOR AND AGING SUSCEPTIBILITY USING BIO-CHAR AND NANO-CLAYRenaldo C. Walters, Elham H. Fini, Taher Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of UV rays. UV rays cause asphalt to oxidize faster, which results in deterioration of asphalt rheological characteristics that can lead to pavement distresses. This study investigates the impact of bio-char and nano-clay of asphalt rheological properties. Two nano scale materials were used for this … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 24 Mar 2014 · 10,525 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModulation of Aging in Yeast Saccharomyces cerevisiae by Roselle Petal Extract (Hibiscus sabdariffa L.)Sarima, Rika Indri Astuti, Anja MeryandiniCellular aging drives diseases. Free radicals are called the main cause of cellular aging. Antioxidants can protect the body from free radical attack by reducing its negative effects. An antioxidant source can be obtained from plants, such as roselle (Hibiscus sabdariffa. L). This research was conducted to analyze the ability of roselle petals extract to increase the life span of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 1 · 6 Apr 2019 · 9,646 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSkin Firming, Skin Smoothing, Skin Blemishes Elimination and Anti-aging Effects of Increased Protein Intake in the Form of Voandzeia hypogeal Seed MealUtoh-Nedosa Uchechukwu AnastasiaStudies on the effect of excess calorie intake on the human body showed that it resulted in accumulation of excess body fat; the darkening of the skin colour and the development of a bumpy skin. Problem statement: The present study investigated the effects of increased protein intake on the human skin and on body fat. The skin firming, skin smoothing … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 28 Dec 2011 · 7,908 accessesView PDFCite
