1. Antioxidant action of alpha lipoic acid on the testis and epididymis of diabetic rats: morphological, sperm and immunohistochemical evaluation
ABSTRACT Introduction Chronic hyperglycemia is caused by diabetes mellitus-committed genital morphophysiology, and oxidative stress is one of the main factors involved in this process. Alpha lipoic acid (ALA) can prevent metabolic and morphological changes in diabetic individuals. Objectives In present study, we evaluated the effects of regular ALA consu

3. Two Novel Donepezil-Lipoic Acid Hybrids: Synthesis, Anticholinesterase and Antioxidant Activities and Theoretical Studies
Alzheimer disease (AD) is a complex disease related to multiple pathogenic mechanisms. A strategy to develop effective drugs is based on the so-called multi-target directed ligands (MTDL) by using hybrid compounds. So, in the present study, we have designed and synthesized two hybrids, containing the indanone-piperidine moiety of donepezil, a drug approved f

4. Hepatoprotective Role of α-Lipoic acid and Thymoquinone in Acetaminophen- Induced Liver Injury: Down-Regulation of COX-2 and flt-1 Expression
ABSTRACT Acetaminophen (APAP) is a widely-used analgesic, while toxic doses of which induce liver injury. Inducible cyclooxygenase-2 (COX-2) is derived prostaglandins which play an anti-inflammatory role in acetaminophen-induced hepatotoxicity. Selective activation of vascular endothelial growth factor (VEGFR1, flt -1) on endothelial cells increased mRNA lev

5. Growth performance, intestinal morphology, and meat quality in relation to alpha-lipoic acid associated with vitamin C and E in broiler chickens under tropical conditions
ABSTRACT This study was conducted to examine the effect of alpha-lipoic acid with vitamin C and E on growth performance, intestinal morphology, and meat quality in broiler chickens under tropical conditions. A total of 288 one-day-old male ROSS 308 chicks (40±0.1 g) were used in a completely randomized design and allotted to one of six dietary treatments to

6. Does alfa lipoic acid prevent liver from methotrexate induced oxidative injury in rats?
PURPOSE: To determine the antioxidant and anti-inflammatory effects of alfa lipoic acid (ALA) on the liver injury induced by methotrexate (MTX) in rats.METHODS:Thirty two rats were randomly assigned into four equal groups; control, ALA, MTX and MTX with ALA groups. Liver injury was performed with a single dose of MTX (20 mg/kg) to groups 3 and 4. The ALA was

7. Therapeutic Options in Idiopathic Burning Mouth Syndrome: Literature Review
Introduction Burning mouth syndrome (BMS) is characterized by a burning sensation in the tongue, palate, lips, or gums of no well-defined etiology. The diagnosis and treatment for primary BMS are controversial. No specific laboratory tests or diagnostic criteria are well established, and the diagnosis is made by excluding all other pos

8. Lipoic acid, but not tempol, preserves vascular compliance and decreases medial calcification in a model of elastocalcinosis
Vascular calcification decreases compliance and increases morbidity. Mechanisms of this process are unclear. The role of oxidative stress and effects of antioxidants have been poorly explored. We investigated effects of the antioxidants lipoic acid (LA) and tempol in a model of atherosclerosis associated with elastocalcinosis. Male New Zealand white rabbits

9. Evaluation of lipoic acid topical application on rats skin wound healing
PURPOSE: To evaluate the effects of lipoic acid (thioctic acid) topical application on wound healing on rats skin, and the consequences of lipoic acid nanoencapsulation on this process. METHODS: The model used was the healing activity on wounds induced by surgical incision on rats skin (n = 44). The parameters analyzed (11 days) were wound healing rate and h

10. Epigallocatechin-3-gallate combined with alpha lipoic acid attenuates high glucose-induced receptor for advanced glycation end products (RAGE) expression in human embryonic kidney cells
Os efeitos antioxidantes de galato de epigalocatequina (EGCG) e ácido alfa lipóico (ALA) foram demonstrados em estudos anteriores. Os efeitos renais da proteção de EGCG e ALA em pacientes com lesão renal ainda estão sob investigação. A finalidade deste estudo é investigar os efeitos anti-inflamatórios e antioxidantes de EGCG e ALA em lesão de cél

11. DETERMINAÇÃO DE ÁCIDO LIPÓICO SOBRE ELETRODO DE GRAFITE PIROLÍTICO MODIFICADO COM FTALOCIANINA DE COBALTO / DETERMINATION OF LIPOIC ACID ON PYROLYTIC GRAPHITE ELECTRODE MODIFIED WITH COBALT PHTHALOCYANINE
Lipoic acid, also known as thioctic acid is a compound organosulfur derived from octanoic acid, which is a saturated fatty acid. It is an antioxidant that has the property of suppressing free radicals in both aqueous and lipid environment, which differs from other antioxidants. Nowadays, various techniques are employed for determining the lipoic acid such as

12. Searching of protein targets for alpha lipoic acid
Ácido alfa lipóico (ALA) é um dos oxidantes mais poderosos e um cofactor em complexos enzimáticos, apesar de seus mecanismos ainda não serem conhecidos. A pesquisa por alvos proteicos de ALA é fundamental para compreender seus processos de sinalização. Uma abordagem bioinformática foi usada a fim de se encontrar alvos hipotéticos para ALA usando o
