BACKGROUND L-carnitine (LC), and its acetylated form, acetyl L-carnitine (ALC), have immense functional capabilities to regulate the oxidative and metabolic status of the female reproductive system. The vulnerability of this system to free radicals demand for advanced strategies to combat them. For this purpose, the 'quasi vitamins' LC and ALC can be used either individually, or in combination ...

Materials and methods: Semen samples were collected from 20 normal healthy volunteers. Specimens were divided into 2 aliquots (A and B) and each diluted in Ham's F-10 media to a uniform concentration of 20X10/mL. Aliquots A, were further divided and into each L-carnitine or acetyl-L-carnitine were added in concentrations of 0, 10, and 30 μM separately. All aliquots were cryopreserved for 3 days...

The therapeutic effect of stroke is hampered by the lack of neuroprotective drugs against ischemic insults beyond the acute phase. Carnitine plays important roles in mitochondrial metabolism and in modulating the ratio of coenzyme A (CoA)/acyl-CoA. Here, we investigate the neuroprotective effects of l-carnitine (LC) and Acetyl-l-carnitine (ALC) pre-treatment on ischemic insults under the same e...

INTRODUCTION This study was designed to determine the short-term effect of acetyl-l-carnitine (ALC) on symptoms of withdrawal in opiate-dependent subjects and animals and, in particular, on pain, given the efficacy of ALC in other typologies of pain. The study consists of 2 branches: a clinical study and a preclinical one, both with a randomized placebo-controlled design. METHODS Thirty subje...

abstract background: sperm cells extracted from testes (tese) have poor chromatin quality and motility. various substances are used in the laboratory to increase sperm motility and improve the art outcomes; however, there are few research which considered improving both sperm motility and chromatin quality. objective: the aim of this investigation was to evaluate the improvement of the testicul...

This study aimed to explore the effect of Bif. Animalis F1-7 on improvement atherosclerotic inflammation. Arteriosclerosis model ApoE-/- mice were orally administered with for 12 weeks. The probiotic intervention reduced plaque areas in aorta and accumulation macrophages, downregulated expression toll-like receptor 4 (TLR4)/nuclear factor‑κB (NFκB) pathway reduce levels inflam...

This study examines the potential efficacy of acetyl-L-carnitine (ALC) to prevent and treat paclitaxel-induced pain. Rats received four intraperitoneal (i.p.) injections of 2 mg/kg paclitaxel on alternate days which, following a short delay induced marked mechanical hypersensitivity. Daily administration of ALC (50 mg/kg and 100 mg/kg; p.o.; concurrently with paclitaxel and for 14 days afterwar...

Objective(s) This study aimed to examine whether acetyl-L-carnitine (ALC) was able to reduce cardiac arrhythmias and infarct size in the ischemic-reperfused isolated rat heart. Materials and Methods The isolated hearts were mounted on a Langendorff apparatus then perfused by a modified Krebs-Henseleit solution during 30 min regional ischemia and 120 min reperfusion (control) or by enriched Kreb...

introduction: in the present study, potential differences between the effects of l-carnitine (lc) and acetyl-lcarnitine (alc) on ischemia/reperfusion (i/r)-induced myocardial infarction size were investigated. methods: male wistar rats were randomly divided into five groups and then anesthetized by sodium pentobarbital. hearts of the animals were removed and quickly mounted on a langendorff app...
