Research ArticleOpen accessPhrase in the titleGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,409 accessesView PDF Cite

Research ArticleOpen accessPhrase 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 PDF Cite

Research ArticleOpen accessEvery word in the titleEffects of Oak Chip Treatments on Quality of Dry White Wines During AgingRongbin Li, Xiaofang Liang, Chunhua Song et al.The objective of the research was to evaluate the effect of different oak chip treatments on quality of Longyan dry white wine during aging. Phenolic substances, antioxidant activity and Cu2+ reduction force were measured. The results showed that wines treated with French oak chips (6 g/L) had significantly higher contents of total phenols (0.083 mg/mL) and flavonoids (0.063 mg/mL), also … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 26 Feb 2020 · 7,235 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleHardening Effects of In-Situ Aging for a Laser Welded Maraging SteelMilton Sergio Fernandes de Lima, Rafael Humberto de Mota Siqueira, Sheila Medeiros de Carvalho, Antonio Jorge AbdallaMaraging steels are ultra-high strength alloys which have been successfully laser welded to obtain structural components. For most of the applications these steels are in an aged state to attain tensile strength up to 1.5 GPa, although welding induces local softening due to dissolution of precipitates. This paper aims to investigate the effect of in-situ aging of the maraging steel … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 12 Nov 2019 · 7,210 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessEvery word in the titlePassage Effect on Aging of Human Umbilical Cord Derived Mesenchymal Stem CellDian Mediana, Isabella Kurnia Liem, Jeanne Adiwinata Pawitan, Noviyanti GoeiTo be used in regenerative medicine, cells should be checked for various conditions, including cell aging. This study aimed to learn senescent profile and its relation to cell viability, proliferation and cell size in various passages, which were done in α-MEM-10% PRP medium, until senescence-associated β-galactosidase (SA-β-Gal) positive cells were found. Stem cells were isolated from umbilical cord tissue by … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 31 Jul 2015 · 8,039 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPurification, Structural Characterization and Anti-Aging and Stress Activities of Cordyceps Mycelium Polysaccharides from Paecilomyces HepialiXiaokang Hu, Huixiu Ma, Guicai Chen et al.This study identified and characterized the bioactive polysaccharide components from Cordyceps mycelium powder (CMP) derived from Paecilomyces hepiali, evaluating their anti-aging and stress-protective activities. Initial screening using Drosophila melanogaster revealed that crude Cordyceps polysaccharides (CCP) exhibited comparable effects to CMP and Cordyceps aqueous extracts (CAE) on natural lifespan and UV stress resistance, suggesting CCP as the primary bioactive component. CCP … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,698 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEpigenetic Regulation of Extracellular Matrix Remodeling in Skin Aging: Mechanisms and InteractionsJiguang Yang, Yusong Shi, Xiaoqing YanSkin aging results from complex interactions between genetic factors, environmental stressors, and epigenetic modifications that regulate extracellular matrix (ECM) remodeling. Accumulation of senescent cells impairs tissue regeneration through mechanisms including telomere shortening, reactive oxygen species accumulation, and ultraviolet (UV) radiation exposure. While epigenetic pathways regulate skin homeostasis, regeneration, and senescence, the specific epigenetic changes occurring during UV exposure, chronological aging, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,458 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Antioxidant Effects of Essential Oil Blends and Individual Oils Using the DPPH Radical-Scavenging AssaySunghun Jang, Jae Kyung KimOxidative stress is recognized as a major contributor to conditions such as cancer, aging, and inflammation. Consequently, there is a growing interest in the use of natural antioxidants, particularly essential oils, owing to their safety benefits and potent antioxidant properties. The aim of this study was to evaluate the antioxidant effects of four essential oil blends (Refresh, Zest, Revitalizing, and … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 5 Jan 2026 · 2,648 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeparation, Purification and Anti-aging Activity of Tobacco PolysaccharidesMengyue Huang, Jingwu Song, Shuaishuai Chang et al.To separate tobacco polysaccharides and investigate their antioxidant and anti-aging properties, crude tobacco polysaccharides were extracted from raw tobacco using hot water, followed by purification through DEAE-52 cellulose column chromatography.
