Launaea acanthodes is extensively used in the semiarid region of Iran for treatment of seizure. However, the underlying mechanism has not been studied well. In our previous study we showed that Launaea acanthodes extract could effectively stimulate GABA release from PC12 cell culture. The critical role of astrocytes in epileptic brain in regulation of neurotransmitter balance in central nervous system encouraged us to investigate the effect of Launaea acanthodes extract on GABA and glutamate release from astrocytes...

PURPOSE: To customize clinical practice guidelines (CPGs) for management of diabetic retinopathy (DR) in the Iranian population. METHODS: Three DR CPGs (The Royal College of Ophthalmologists 2013, American Academy of Ophthalmology [Preferred Practice Pattern 2012], and Australian Diabetes Society 2008) were selected from the literature using the AGREE tool. Clinical questions were designed and summarized into four tables by the customization team. The components of the clinical questions along with pertinent recommendations extracted from the above-mentioned CPGs; details of the supporting articles and their levels of evidence; clinical recommendations considering clinical benefits, cost and side effects; and revised recommendations based on customization capability (applicability, acceptability, external validity) were recorded in 4 tables, respectively...

Due to widespread exposure of human being to various sources of static magnetic fields (SMF), their effect on the spatial and temporal status of structure, arrangement, and polymerization of tubulin was studied at the molecular level. The intrinsic fluorescence intensity of tubulin was increased by SMF, indicating the repositioning of tryptophan and tyrosine residues. Circular Dichroism spectroscopy revealed variations in the ratios of alpha helix, beta, and random coil structures of tubulin as a result of exposure to SMF at 100, 200, and 300 mT...

In many neurodegenerative diseases, formation of protein fibrillar aggregates has been observed as a major pathological change. Neurofibrillary tangles, mainly composed of fibrils formed by the microtubule-associated protein; Tau, are a hallmark of a group of neurodegenerative diseases such as Alzheimer's disease. Tau belongs to the class of natively unfolded proteins and partially folds into an ordered β-structure during aggregation. Polyanionic cofactors such as heparin are commonly used as inducer of Tau aggregation in vitro...

BACKGROUND: Sporadic Alzheimer's Disease (SAD) is caused by genetic risk factors, aging and oxidative stresses. The herbal extract of Rosa canina (R. canina), Tanacetum vulgare (T. vulgare) and Urtica dioica (U. dioica) has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. In this study, the neuroprotective effects of this herbal extract in the rat model of SAD was investigated. METHODS: The rats were divided into control, sham, model, herbal extract -treated and ethanol-treated groups...

In acute myeloid leukemia (AML), despite the acceptance of standard intensive chemotherapy as an optimal induction regimen for all age groups, in the elderly patients, the best treatment should meet the challenge of multiple factors like age, comorbidities, and cytogenetics, making them ineligible for standard induction chemotherapy. Using the current low-intensity therapies like decitabine, azacitidine, and low-dose cytarabine as a single arm, outcomes for these patients remain poor. As a histone deacetylase inhibitor valproic acid (VPA) exhibit anticancer activity by triggering apoptosis, the mechanism of which is not yet completely clarified...

Focal choroidal excavation (FCE) was first reported as a choroidal posteriorly excavated zone without any scleral change. Choroidal excavation also divided into conforming and nonconforming type. Numerous reports demonstrated association between FCE and other disease such as choroidal neovascularization and central serous choroidoretinopathy. Here, we report a rare case of FCE in a patient with Best disease. The patient was diagnosed by spectoral domain optical coherence tomography (SD-OCT). To the best of our knowledge, our patient is the second report of choroidal excavation in Best vitelliform macular dystrophy...

Millions of patients are either slowly losing their vision or are already blind due to retinal degenerative diseases such as retinitis pigmentosa (RP) and age-related macular degeneration (AMD) or because of accidents or injuries. Employment of artificial means to treat extreme vision impairment has come closer to reality during the past few decades. Currently, many research groups work towards effective solutions to restore a rudimentary sense of vision to the blind. Aside from the efforts being put on replacing damaged parts of the retina by engineered living tissues or microfabricated photoreceptor arrays, implantable electronic microsystems, referred to as visual prostheses, are also sought as promising solutions to restore vision...

PURPOSE: To compare the outcomes of photodynamic therapy (PDT) combined with intravitreal bevacizumab (IVB) with versus without intravitreal triamcinolone (IVT) in neovascular age-related macular degeneration (AMD). METHODS: Eighty-four eyes with active CNV secondary to AMD with no prior treatment were enrolled and followed for 1-year. Eligible eyes were randomly assigned to either PDT/IVB or PDT/IVB/IVT. The main outcome measure was change in best-corrected visual acuity (BCVA)...

BACKGROUND: Scanning with technetium-99m methoxyisobutylisonitrile (Tc-MIBI) is recommended for evaluating thyroid nodule metabolism. In addition, it may help differentiate between benign and malignant nodules; however, the efficacy of this technique has not been fully elucidated. Therefore, it is not currently performed for routine clinical application. This prospective study was conducted to investigate the clinical significance of Tc-MIBI scintigraphy in the assessment of patients with cold thyroid nodules...

PURPOSE: To compare the short-term outcomes of intravitreal bevacizumab (IVB) with the combination of IVB and intravitreal triamcinolone acetonide (IVB/IVT) for treatment of neovascular age-related macular degeneration (AMD). METHODS: This randomized clinical trial was performed on 92 eyes of 90 patients with subfoveal and juxtafoveal choroidal neovascularization (CNV) secondary to AMD. The eyes were randomly assigned to receive IVB 1.25 mg alone (53 eyes) or in combination with IVT 2 mg (39 eyes)...

Objective  To determine the geographical distribution of Leishmania species causing cutaneous leishmaniasis (CL) and to study the genetic heterogeneity of Leishmania major isolates from different endemic areas of Iran. Methods  A total of 341 isolates from lesions of patients living in 11 provinces of Iran were grown in culture medium and inoculated to BALB/c mice to detect possible visceralisation. The species were identified by isoenzyme analysis using a battery of six enzymes and kinetoplast (k) DNA-PCR technique...

Although the pathological relationship between parathyroid and thyroid diseases is common, an association between parathyroid adenoma and thyroid cancer is rare. Concomitant thyroid cancer in patients with primary hyperparathyroidism (pHPT) has been reported at varying frequencies. WE present here a 23-year-old man who had papillary thyroid carcinoma in the right thyroid lobe and a parathyroid adenoma in the left thyroid lobe, which were confirmed surgically.

Arsenical compounds exhibit a differential toxicity to cancer cells. Microtubules are a primary target of a number of anticancer drugs, such as arsenical compounds. The interaction of 1-NAA (1-naphthylarsonic acid) has been investigated on microtubule polymerization under in vitro and cellular conditions. Microtubules were extracted from sheep brain. Transmission electron microscopy was used to show microtubule structure in the presence of 1-NAA. Computational docking method was applied for the discovery of ligand-binding sites on the microtubular proteins...

PURPOSE: To determine whether combined intravitreal bevacizumab (IVB) and triamcinolone (IVT) is more effective than IVB alone in neovascular age-related macular degeneration. METHODS: This was a prospective, randomized clinical trial performed at two centers. Eligible eyes were assigned randomly to one of the two study arms. In the IVB group, 3 consecutive injections of 1.25 mg of bevacizumab were given 6 weeks apart, while in the IVB/IVT group, the first of the triple IVB injections was combined with 2 mg of IVB...
