Published: Oct. 20, 2022

Aging is a very complex process that accompanied by degenerative impairment in many of the major functions human body over time. This inevitable influenced hereditary factors, lifestyle, and environmental influences such as xenobiotic pollution, infectious agents, UV radiation, diet-borne toxins, so on. Many external internal signs symptoms are related with aging senescence, including skin dryness wrinkles, atherosclerosis, diabetes, neurodegenerative disorders, cancer, etc. Oxidative stress, consequence imbalance between pro- antioxidants, one main provoking factors causing aging-related damages concerns, due to generation highly reactive byproducts oxygen nitrogen species during metabolism, which result cellular damage apoptosis. Antioxidants can prevent these processes extend healthy longevity ability inhibit formation free radicals or interrupt their propagation, thereby lowering level oxidative stress. review focuses on supporting antioxidant system organism balancing diet through consumption necessary amount natural ingredients, vitamins, minerals, polyunsaturated fatty acids (PUFA), essential amino acids, probiotics, plants’ fibers, nutritional supplements, polyphenols, some phytoextracts, drinking water.

Polyphenols in Metabolic Diseases

Molecules, Journal Year: 2022, Volume and Issue: 27(19), P. 6280 - 6280

Published: Sept. 23, 2022

Polyphenols (PPs) are a large group of phytochemicals containing phenolic rings with two or more hydroxyl groups. They possess powerful antioxidant properties, multiple therapeutic effects, and possible health benefits in vivo vitro, as well reported clinical studies. Considering their free-radical scavenging anti-inflammatory these substances can be used to treat different kinds conditions associated metabolic disorders. Many symptoms syndrome (MtS), including obesity, dyslipidemia, atherosclerosis, elevated blood sugar, accelerating aging, liver intoxication, hypertension, cancer neurodegenerative disorders, substantially relieved by dietary PPs. The present study explores the bioprotective properties underlying mechanisms A detailed understanding natural compounds will open up new opportunities for producing unique PP-rich medicinal plans, ultimately affirming benefits.

The Role of Antioxidants in the Interplay between Oxidative Stress and Senescence

Antioxidants, Journal Year: 2022, Volume and Issue: 11(7), P. 1224 - 1224

Published: June 22, 2022

Cellular senescence is an irreversible state of cell cycle arrest occurring in response to stressful stimuli, such as telomere attrition, DNA damage, reactive oxygen species, and oncogenic proteins. Although beneficial protective several physiological processes, excessive senescent burden has been involved various pathological conditions including aging, tissue dysfunction chronic diseases. Oxidative stress (OS) can drive due a loss balance between pro-oxidant stimuli antioxidant defences. Therefore, the identification characterization compounds capable preventing or counteracting phenotype major interest. However, despite considerable number studies, comprehensive overview main molecules OS-induced still lacking. Here, besides brief description molecular mechanisms implicated OS-mediated we review discuss role enzymes, mitochondria-targeting compounds, vitamins, carotenoids, organosulfur nitrogen non-protein molecules, minerals, flavonoids, non-flavonoids with anti-aging potential, therefore offering insights into innovative lifespan-extending approaches.

Neuroprotective Potentials of Flavonoids: Experimental Studies and Mechanisms of Action

Antioxidants, Journal Year: 2023, Volume and Issue: 12(2), P. 280 - 280

Published: Jan. 27, 2023

Neurological and neurodegenerative diseases, particularly those related to aging, are on the rise, but drug therapies rarely curative. Functional disorders organic degeneration of nervous tissue often have complex causes, in which phenomena oxidative stress, inflammation cytotoxicity intertwined. For these reasons, search for natural substances that can slow down or counteract pathologies has increased rapidly over last two decades. In this paper, studies neuroprotective effects flavonoids (especially most widely used, hesperidin quercetin) animal models depression, neurotoxicity, Alzheimer’s disease (AD) Parkinson’s reviewed. The literature topics amounts a few hundred publications vitro vivo (notably rodents) provides us with very detailed picture action mechanisms targets substances. These include decrease enzymes produce reactive oxygen ferroptosis, inhibition mono-amine oxidases, stimulation Nrf2/ARE system, induction brain-derived neurotrophic factor production and, case AD, prevention amyloid-beta aggregation. neuroinflammatory processes been documented as cytokine formation (mainly TNF-alpha IL-1beta) by microglia astrocytes, modulating number regulatory proteins such Nf-kB NLRP3/inflammasome. Although clinical trials humans still scarce, preclinical allow consider hesperidin, quercetin, other interesting safe dietary molecules be further investigated complementary treatments order prevent diseases moderate their deleterious effects.

Cryopreservation of bioflavonoid-rich plant sources and bioflavonoid-microcapsules: emerging technologies for preserving bioactivity and enhancing nutraceutical applications

Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: Sept. 14, 2023

Bioflavonoids are natural polyphenolic secondary metabolites that medicinal. These compounds possess antitumor, cardioprotective, anti-inflammatory, antimicrobial, antiviral, and anti-psoriasis properties to mention a few. Plant species contain bioflavonoids should be preserved as such. Also, the bioactivity of neutraceutical is compromised following extraction due their sensitivity environmental factors like light, pH, temperature. In other words, bioflavonoids’ shelf-life affected. Scientists noticed have low solubility properties, poor absorption, bioavailability consumption. Researchers came up with methods encapsulate in order circumvent challenges above also mask unpleasant these chemicals may have. Besides, scientists cryopreserve plant bioflavonoids. this review, we discuss cryopreservation bioflavonoid microencapsulation focusing mainly on vitrification, slow freezing, freeze-drying techniques. addition, highlight techniques, medicinal challenges, future perspectives Regardless uniqueness preserve sources bioactivity, there reported. Freeze-drying technology costly. Cryoprotectants damage integrity cells, say least. working very hard overcome challenges. Encapsulating via coaxial electrospray then cryopreserving micro/nanocapsules produced can interesting.
