Nowadays, polymer nanofibers have gained attention due to remarkable characteristics such as high porosity and large surface area to volume ratio. Among their fabrication methods, electrospinning technique has been attracted as a simple and reproducible approach. It is a versatile, simple and cost-effective technique for the production of continuous nanofibers with acceptable characteristics su...

BACKGROUND A large number of artificial tears is widely used to treat dry eye symptoms. To test the efficacy of these drugs independent of individual parameters in vitro models are required. As described previously, we employed a reproducible in vitro cell culture system to evaluate the desiccation protection capability of some artificial tears. In THE PRESENT PAPER DATA IS PRESENTED OF ANOTHER...

Invocation of cellular immunity by epitopic peptides remains largely dependent on empirically developed protocols, such as interfusion of aluminum salts or emulsification using terpenoids and surfactants. To explore novel vaccine formulation, epitopic peptide motifs were co-programmed with structural motifs to produce artificial antigens using our "motif-programming" approach. As a proof of con...

a complicated and controversial subject in obstetrics i.e., toxemia of pregnancy is looked upon, both from an anesthesiological and obstetrical point of view. as pre-eclampsia and eclampsia involve immediate treatment and obstetric considerations, the choice between epidural and general anesthesia becomes necessary when cesarean section is contemplated. apart from the pathophysiology of the ves...

background: diminished libido and sexual dysfunction are unusually common among male epileptic patients. the most important etiologic factor may be antiepileptic drugs (aeds)-induced androgen deficiency. we compared reproductive hormone levels among men with epilepsy taking various aeds and normal controls. methods: subjects were 59 male epileptic patients who aged 24 ± 5 years. they had been r...

objective(s): anti-epileptic drugs (aeds) have the potential to affect fetal development throughout pregnancy. considering the broad therapeutic indications of pregabalin (pgb), its potential teratogenic effects and the levels of homocysteine have been studied.   materials and methods: timed-pregnant mice received one of three doses of pgb (20, 40 or 80 mg/kg/day) or the vehicle control during ...

objectives: psychotropic drug use in the elderly with chronic schizophrenia is an important issue in the field of psychiatry. the main goal of this study was to clarify the pattern of such drug use in these patients, in order to consider such therapy plan and focus on its cost attributing measures, for a more reasonable quality of care program. methods: in this descriptive study, participants i...

BACKGROUND Mesenchymal stem cells (MSCs) hold promise for application in adult stem cell-mediated regenerative medicine in bone remodeling and fracture repair. MSCs in vitro can be directed to osteogenic lineage by dexamethasone (DEX); however, the use of DEX is not practical in clinical settings because of adverse side effects such as glucocorticoid-induced osteoporosis. For identifying substa...

Guanine DNA quadruplexes are interesting and important biological objects because they represent potential targets for regulatory drugs. Their use as building blocks for biomaterial applications is also being investigated. This contribution reports the in silico design of artificial building blocks derived from xanthine. Methods of quantum chemistry were used to evaluate the properties of xanth...

Type 1 diabetes mellitus (T1DM) is a chronic life-threatening condition whose incidence in the UK has doubled every 20 years since 1945 (Diabetes UK, 2010). Whilst intensive insulin therapy has been shown to reduce the incidence of long-term vascular complications in T1DM patients, it has also been shown to increase the risk of severe hypoglycaemia by 3-fold. Clinical islet transplantation has ...
