Dietary interventions have proven to be the most robust and consistent means of ameliorating the diseases and dysfunctions of aging. A large literature includes both quantitative (caloric restriction [CR]) and qualitative (micronutrients, antioxidants, etc.) alterations of nutrient and caloric...

Fruit polyphenolics and brain aging: nutritional interventions targeting age‐related neuronal and behavioral deficits

Stem education interventions

GSID: yFSpNLBLl58J
RL Galli, B Shukitt‐Hale, KA Youdim… - Annals of the New …, 2002 - Wiley Online Library

Nutritional interventions, in this case, increasing dietary intake of fruits and vegetables, can retard and even reverse age‐related declines in brain function and in cognitive and motor performance in rats. Our lab has shown that as Fischer 344 rats...

The main objective of this investigation was to evaluate fruits of C. chinense accessions for their concentration of β-carotene, ascorbic acid, and phenols for use as parents in breeding for these phytochemicals. Mature fruits of 63 accessions of C....

The role of oxidative stress in menopause.

Journal of mid-life health

Doshi SB, Agarwal A.
PMID: 24672185
J Midlife Health. 2013 Jul;4(3):140-6. doi: 10.4103/0976-7800.118990.

This review will discuss the concept of reproductive aging, which includes the definition of menopause, its symptoms, and predisposing conditions. It will elaborate upon the contributory factors implicated in the pathogenesis of menopause, focusing most prominently on oxidative stress....

Multi-faceted reactivity of alkyltellurophenols towards peroxyl radicals: catalytic antioxidant versus thiol-depletion effect.

Chemistry (Weinheim an der Bergstrasse, Germany)

Amorati R, Valgimigli L, Dinér P, Bakhtiari K, Saeedi M, Engman L.
PMID: 23576474
Chemistry. 2013 Jun 03;19(23):7510-22. doi: 10.1002/chem.201300451. Epub 2013 Apr 10.

Hydroxyaryl alkyl tellurides are effective antioxidants both in organic solution and aqueous biphasic systems. They react by an unconventional mechanism with ROO(·) radicals with rate constants as high as 10(7)  M(-1)  s(-1) at 303 K, outperforming common phenols. The...

Green algae in alpine biological soil crust communities: acclimation strategies against ultraviolet radiation and dehydration.

Biodiversity and conservation

Karsten U, Holzinger A.
PMID: 24954980
Biodivers Conserv. 2014;23:1845-1858. doi: 10.1007/s10531-014-0653-2. Epub 2014 Mar 02.

Green algae are major components of biological soil crusts in alpine habitats. Together with cyanobacteria, fungi and lichens, green algae form a pioneer community important for the organisms that will succeed them. In their high altitudinal habitat these algae...

Mitochondria, endothelial cell function, and vascular diseases.

Frontiers in physiology

Tang X, Luo YX, Chen HZ, Liu DP.
PMID: 24834056
Front Physiol. 2014 May 06;5:175. doi: 10.3389/fphys.2014.00175. eCollection 2014.

Mitochondria are perhaps the most sophisticated and dynamic responsive sensing systems in eukaryotic cells. The role of mitochondria goes beyond their capacity to create molecular fuel and includes the generation of reactive oxygen species, the regulation of calcium, and...

The effect of almond consumption on elements of endurance exercise performance in trained athletes.

Journal of the International Society of Sports Nutrition

Yi M, Fu J, Zhou L, Gao H, Fan C, Shao J, Xu B, Wang Q, Li J, Huang G, Lapsley K, Blumberg JB, Chen CY.

BACKGROUND: Almonds are a healthy tree nut food with high nutrient density. Their consumption has been shown to ameliorate oxidative stress, inflammation, etc. The objective of the study was to examine the effect of almonds on elements of endurance...

Phytochemicals: Extraction, Isolation, and Identification of Bioactive Compounds from Plant Extracts.

Plants (Basel, Switzerland)

Altemimi A, Lakhssassi N, Baharlouei A, Watson DG, Lightfoot DA.
PMID: 28937585
Plants (Basel). 2017 Sep 22;6(4). doi: 10.3390/plants6040042.

There are concerns about using synthetic phenolic antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) as food additives because of the reported negative effects on human health. Thus, a replacement of these synthetics by antioxidant extractions from...
