objective(s) the role of therapeutic drug monitoring (tdm) in patient care has grown rapidly since its introduction three decades ago. the aim of present study was to evaluate the possible relationship between serum levels and the clinical response of valproic acid (vpa). materials and methods in the present study we evaluated a homogeneous group of adult patients receiving vpa monotherapy. a t...

BACKGROUND/AIM We have previously reported that caffeine can enhance chemotherapy efficacy of bone and soft-tissue sarcoma via cell-cycle perturbation. Valproic acid has histone deacetylase (HDAC) inhibitory activity. The present study aimed to investigate the efficacy of the combination of valproic acid and caffeine on human osteosarcoma cells in vitro and in orthotopic nude-mouse models. MA...

objective(s):the limited homing potential of bone-marrow-derived mesenchymal stem cells (bm-msc) is the key obstacle in msc-based therapy. it is believed that chemokines and chemokine receptor interactions play key roles in cellular processes associated with migration. meanwhile, mscs express a low level of distinct chemokine receptors and they even lose these receptors on their surface after a...

background epilepsy is a chronic neurological disease with the prevalence of around one percent. despite the introductions of several anti-epileptic drugs, around 1/3 of epileptic patients are resistant to the anti-epileptic medications. objectives considering the evidence regarding the anti-oxidant action of vitamin e and its beneficiary effect in the treatment of epilepsy, we investigated the...

The vaporization enthalpy of valproic acid (2-propylpentanoic acid) is reported, and the vapor pressures of a series on aliphatic carboxylic acids are used to evaluate its vapor pressure as a function of temperature. The vaporization enthalpy was derived by correlation-gas chromatography. This resulted in a vaporization enthalpy, ΔHvap(298.15 K) of (74.8 ± 2.4) kJ·mol−1. Vapor pressures from T/...

The studies of cell plasticity and differentiation abilities are important problems in modern cellular biology. The use of histone deacetylase inhibitor - valproic acid is a promising approach to increasing the differentiation efficiency of various cell types. In this paper we investigate the ability of mouse submandibular salivary gland cells to differentiate into the hepatic direction and the...

background: valproic acid (vpa) is an effective antiepileptic drug widely used worldwide. despite several studies indicating the usefulness of intravenous l-carnitine in the treatment of vpa poisoning, this drug is not readily available in iran. the aim of this study was to determine whether supportive care without antidote would result in acceptable outcomes in vpa poisoned patients. materials...

traffic accident has increased in the last decade. one of the most important outcomes of accident is spinal cord injury (sci). so, cell therapy is obtained a greater attention in most fields of medicine because of its potential for incurable diseases through replacing of dead cells. the current study aims to describe the important of locomotor functional and structural connection of the spinal ...

background valproic acid is widely used as an anticonvulsant and mood-stabilizing drug in the treatment of epilepsy. determination of serum valproic acid is required in epilepsy therapy for efficient control of seizures. objectives in the present study, the gas chromatography method was applied to determine serum valproic acid and resulting data were compared with those obtained by high perform...

Valproic acid is widely used in the treatment of many diseases. It has common side effects such as nausea, vomiting, diarrhea, dizziness, tremor, hair loss, thrombocytopenia. can rarely cause eosinophilic pleuropericardial effusion. Case report; a 31-year-old male patient who had been using valproic since childhood due to epilepsy presented with respiratory distress. Eosinophilic effusion was d...
