J Clin Diagn Res. 2016 Mar;10(3):FC12-5. doi: 10.7860/JCDR/2016/16976.7499. Epub 2016 Mar 01.

INTRODUCTION: One out of four prescriptions in out-patient departments contains a gastro-protective drug (APUD) - PPI/ H2 Blockers/ Antacids/ Ulcer Protective's. These drugs should be prescribed only when there is a justified indication. To assess the prescriptions of gastro-protective...

Shirazi A, Mihandoost E, Mahdavi SR, Mohseni M.
PMID: 25992214
Oncol Rev. 2012 Oct 02;6(2):e16. doi: 10.4081/oncol.2012.e16. eCollection 2012 Oct 02.

Ionizing radiation interacts with biological systems to produce reactive oxygen species and reactive nitrogen species which attack various cellular components. Radio-protectors act as prophylactic agents to shield healthy cells and tissues from the harmful effects of radiation. Past research...

Carotenoids Assist in Cyanobacterial Photosystem II Assembly and Function.

Frontiers in plant science

Zakar T, Laczko-Dobos H, Toth TN, Gombos Z.
PMID: 27014318
Front Plant Sci. 2016 Mar 10;7:295. doi: 10.3389/fpls.2016.00295. eCollection 2016.

Carotenoids (carotenes and xanthophylls) are ubiquitous constituents of living organisms. They are protective agents against oxidative stresses and serve as modulators of membrane microviscosity. As antioxidants they can protect photosynthetic organisms from free radicals like reactive oxygen species that...

Effects of L-arginine pre-treatment in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson's diseases in Balb/c mice.

Iranian journal of neurology

Hami J, Hosseini M, Shahi S, Lotfi N, Talebi A, Afshar M.
PMID: 26885338
Iran J Neurol. 2015 Oct 07;14(4):195-203.

BACKGROUND: Parkinson's disease (PD) is a common neurodegenerative disease resulting from the degeneration of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNc). Increasing evidence demonstrated that mice treated intranasally with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) suffered impairments in motor functions...

Effect of topical application of antioxidants and free radical scavengers on protection of hairless mouse skin exposed to chronic doses of ultraviolet B.

Skin Res Technol. 1998 Nov;4(4):200-4. doi: 10.1111/j.1600-0846.1998.tb00111.x.

BACKGROUND/AIMS: Within the past three decades, there has emerged a greater awareness of the molecular effects of solar rays especially ultraviolet radiation (UV-R), to the extent that the harmful effects of solar radiation are recognized not only by molecular...

Size-controlled synthesis of mesoporous palladium nanoparticles as highly active and stable electrocatalysts.

Chemical communications (Cambridge, England)

Li C, Sato T, Yamauchi Y.
PMID: 25144782
Chem Commun (Camb). 2014 Oct 11;50(79):11753-6. doi: 10.1039/c4cc04955a.

We report a solution phase synthesis of monodispersed mesoporous Pd nanoparticles (MPNs) with narrow particle size distributions. The average particle sizes can be controlled to a range of 25 nm to 42 nm, by utilizing cationic surfactants (as structure-directing...

Reumatismo

Adami S, Viapiana O.
PMID: 12461574
Reumatismo. 2001;53(1):18-25. doi: 10.4081/reumatismo.2001.18.

Osteoarthritis is generally considered a degenerative disorder driven by mechanical alteration of joint cartilage, with the bone changes being reactive to cartilage changes. According to this pathogenetic mechanism the only strategy to prevent osteoarthritis should be based on the...

Efficient transesterification/acylation reactions mediated by N-heterocyclic carbene catalysts.

The Journal of organic chemistry

Grasa GA, Güveli T, Singh R, Nolan SP.
PMID: 12662057
J Org Chem. 2003 Apr 04;68(7):2812-9. doi: 10.1021/jo0267551.

Imidazol-2-ylidenes, a family of N-heterocyclic carbenes (NHC), are efficient catalysts in the transesterification involving numerous esters and alcohols. Low catalyst loadings of aryl- or alkyl-substituted NHC catalysts mediate the acylation of alcohols with enol acetates in short reaction times...

THE OXIDATIVE BURST IN PLANT DISEASE RESISTANCE.

Annual review of plant physiology and plant molecular biology

Lamb C, Dixon RA.
PMID: 15012264
Annu Rev Plant Physiol Plant Mol Biol. 1997 Jun;48:251-275. doi: 10.1146/annurev.arplant.48.1.251.

Rapid generation of superoxide and accumulation of H2O2 is a characteristic early feature of the hypersensitive response following perception of pathogen avirulence signals. Emerging data indicate that the oxidative burst reflects activation of a membrane-bound NADPH oxidase closely resembling...

The etiology of Parkinson's disease (PD) is still unknown. Genetic factors and environmental exposure have been suggested in the etiopathogenesis of the disease. But the cause of dopaminergic cell loss in patients with PD remains unknown. During the last...

Cytoprotection and healing: two unequal brethren.

Inflammopharmacology
