The most common cause of male infertility is idiopathic oligo-, and or astheno-, and /or teratozoospermia. In such cases, anti-estrogens, antioxidants (vitamins and trace elements) or carnitines are used, but the evidence on their effectiveness is inconsistent; there are currently no published studies exploring their concurrent use. AIM: To investigate the efficacy and safety of the L- and acetyl-L-carnitine complex, vitamins A, E, C, selenium, zinc and other antioxidants ("SpermActin" + "More than vitamins") in combination with clomiphene citrate (CC) in managing male idiopathic infertility in the form of oligo, and/or astheno-, and/or teratozoospermia...

INTRODUCTION: Infertility affects an estimated 15% of couples globally. Male factor infertility accounts for about a half of infertility cases. About 40% of infertile men have varicocele. The aim of this study was to investigate the efficacy and safety of a complex of acetyl-L-carnitine, L-carnitine fumarate and alpha-lipoic acid (SpermActin-forte) (SA) for adjuvant antioxidant therapy after microsurgical varicocelectomy (MVE) in men with varicocele and assess its impact on the level of DNA fragmentation in sperm cells...

RATIONALE: The matrix plays an essential role in defining detection limits and ionization yields of analytes in matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis. Small molecule MALDI-MS analyses commonly suffer from the high background interference generated from matrices. Moreover, the inhomogeneous crystallization of some matrices, such as 2,5-dihydroxybenzoic acid (DHB), is to the detriment of the quality or repeatability of detection. We have found that N-butyl-4-hydroxy-1,8-naphthalimide (BHN) can provide improved performance as a matrix for small molecule analysis...

Neuroinflammation is the inflammation of nervous tissue that can lead to neurodegeneration. Brain-derived neurotrophic factor (BDNF) is a neurotrophin which affects growth, function and survival of neurons, enhances the stabilization of synapses, regulates synaptic function and branching of dendrites and axons. Brain-derived neurotrophic factor is believed to be involved in the pathophysiology of central nervous system (CNS) diseases associated with neuroinflamation. The aim of this study was to investigate new protective and therapeutic effect of acetyl-l-carnitine (ALCAR) in neuroinflammation...

We previously reported the ability of dietary supplementation with acetyl-l-carnitine (ALCAR) to prevent age-related decreases of mitochondrial biogenesis in skeletal muscle and liver of old rats. Here, we investigate the effects of ALCAR supplementation in cerebral hemispheres and cerebellum of old rats by analyzing several parameters linked to mitochondrial biogenesis, mitochondrial dynamics and antioxidant defenses. We measured the level of the coactivators PGC-1α and PGC-1β and of the factors regulating mitochondrial biogenesis, finding an age-related decrease of PGC-1β, whereas PGC-1α level was unvaried...

It has become widely acknowledged that astrocytes play essential roles in maintaining physiological central nervous system (CNS) activities. Astrocytes fulfill their roles partly through the manipulation of their plasma membrane transporter functions, and therefore these transporters have been regarded as promising drug targets for various CNS diseases. A representative example is excitatory amino acid transporter 2 (EAAT2), which works as a critical regulator of excitatory signal transduction through its glutamate uptake activity at the tripartite synapse...

It is well known that acetyl-l-carnitine (ALC) has various neuroprotective effects against neurodegenerative diseases. In addition, it has been reported that ALC facilitates myelination of regenerated axons after peripheral nerve injuries. We previously reported that spontaneous regeneration of the lateral olfactory tract (LOT), the main fiber tract of the central olfactory system, consistently occurred in newborn rats and a majority of these regenerated fibers were unmyelinated in neonatally LOT-transected young adult rats...

Parkinson's disease (PD) is characterized by the degeneration of dopaminergic neurons in the nigrostriatal pathway that leading to progressive motor and nonmotor symptoms. The formation of newborn neurons in the adult hippocampus is affected by many factors such as anxiety, depression and impairment in learning and memory that are commonly observed nonmotor symptoms in PD, indicating the role of adult neurogenesis in PD pathophysiology. Acetyl-l-carnitine (ALCAR), regulate mitochondrial metabolism and has been reported to improve cognitive functions in different neurodegenerative disorders through an unknown mechanism...

Cyclosporine A (CsA) is an immunosuppressive drug commonly used in organ transplant patients to prevent allograft rejections. Ketamine is a pediatric anesthetic that noncompetitively inhibits the calcium-permeable N-methyl-d-aspartic acid receptors. Adverse drug-drug interaction effects between ketamine and CsA have been reported in mammals and humans. However, the mechanism of such drug-drug interaction is unclear. We have previously reported adverse effects of combination drugs, such as verapamil/ketamine and shown the mechanism through intervention by other drugs in zebrafish embryos...

BACKGROUND: Peripheral nerve injuries repair is still among the most challenging and concern-raising tasks in neurosurgery. The effect of an acetyl-L-carnitin-loaded silicone tube as an in-situ delivery system in defects bridging was studied using a rat sciatic nerve regeneration model. METHODS: A 10-mm sciatic nerve defect was bridged using a silicone tube (SIL/ALC) filled with 10 µL acetyl-L-carnitine (100 ng/mL). In the control group (SIL), the tube was filled with the same volume of the phosphate-buffered solution...

A long history of diabetes mellitus and increasing age are associated with the onset of diabetic neuropathy, a painful and highly disabling complication with a prevalence peaking at 50% among elderly diabetic patients. Acetyl-L-carnitine (ALC) is a molecule derived from the acetylation of carnitine in the mitochondria that has an essential role in energy production. It has recently been proposed as a therapy to improve the symptoms of diabetic neuropathy. ALC is widely distributed in mammalian tissues, including the brain, blood-brain barrier, brain neurons, and astrocytes...

L-Carnitine functions to transport long chain fatty acyl-CoAs into the mitochondria for degradation by β-oxidation. Treatment with L-carnitine can ameliorate metabolic imbalances in many inborn errors of metabolism. In recent years there has been considerable interest in the therapeutic potential of L-carnitine and its acetylated derivative acetyl-L-carnitine (ALCAR) for neuroprotection in a number of disorders including hypoxia-ischemia, traumatic brain injury, Alzheimer's disease and in conditions leading to central or peripheral nervous system injury...

BACKGROUND: Neuronal death may be an overlooked and unaddressed component of disability following neonatal nerve injuries, such as obstetric brachial plexus injury. N-acetylcysteine and acetyl-L-carnitine improve survival of neurons after adult nerve injury, but it is unknown whether they improve survival after neonatal injury, when neurons are most susceptible to retrograde neuronal death. The authors' objective was to examine whether N-acetylcysteine or acetyl-L-carnitine treatment improves survival of neonatal motor or sensory neurons in a rat model of neonatal nerve injury...

Injury to sensory afferents may contribute to the peripheral neuropathies that develop after administration of chemotherapeutic agents. Manipulations that increase levels of nicotinamide adenine dinucleotide (NAD) can protect against neuronal injury. This study examined whether nicotinamide riboside (NR), a third form of vitamin B3 and precursor of NAD, diminishes tactile hypersensitivity and place escape-avoidance behaviors in a rodent model of paclitaxel-induced peripheral neuropathy. Female Sprague-Dawley rats received 3 intravenous injections of 6...

Perinatal hypoxia ischemia (HI) is a significant cause of brain injury in surviving infants. Although hypothermia improves outcomes in some infants, additional therapies are needed since about 40% of infants still have a poor outcome. Acetyl-L-carnitine (ALCAR), an acetylated derivative of L-carnitine, protected against early changes in brain metabolites and mitochondrial function after HI on postnatal day (PND) 7 in a rat pup model of near-term HI injury. However, its efficacy in long-term structural and functional outcomes remains unexplored...
