Alzheimer's disease (AD) is one of the most common types of neurodegenerative diseases which is accompanied by irreversible neuronal damage, learning difficulties, memory impairments, and cognitive disorders. The cholinergic system is destroyed during AD pathogenesis, leading to the major symptoms of the disease. Although in severe stages AD is life threatening, to date no absolute treatment has been found for this illness and some palliative options are available. The aim of this study was to investigate the effect of fullerene (C60) aqueous suspension (FAS) on improving spatial memory in amnesic male Wistar rats (weighing 200 ± 20 g) and to further compare the results with that of donepezil (DNPZL) as a standard drug...

In the present study, we successfully synthesized nanocarriers (NCs) based on Y-shaped miktoarm copolymers, Poly Ethylene Glycol-Lysine-(Poly Caprolactone)2 (PEG-Lys-PCL2 ), which were loaded by baicalein (B) through the nanoprecipitation process to assess their in-vitro and in-vivo properties. We applied various methods and measurements including proton nuclear magnetic resonance (HNMR), dynamic light scattering (DLS), differential scanning calorimetry (DSC), Fourier-transform infrared spectroscopy (FTIR), MTT assay, hemolysis test, lethal dose, real-time PCR, and Morris water maze...

Background: The best method for repairing intertrochanteric fractures is still controversial. The fixation methods include extramedullary (EM) and intramedullary (IM). Studies that compare IM and EM fixations for unstable hip fractures are rare. In this study, our goal was to compare the efficacy of EM and IM fixation in treatment of unstable intertrochanteric fractures. Methods: A total of 113 patients with unstable intertrochanteric were randomized in this cohort study between March 2016 and June 2018 in trauma center of Kashani and Alzahra Hospitals, Isfahan, Iran...

Objectives: Blocking of vascular endothelial growth factor (VEGF) plays a pivotal role in inhibition of metastasis and is a target for development of anti-angiogenic agents. In this study, a peptide-based vaccine was designed and its potential for induction of humoral immune responses, generation of neutralizing antibodies, inhibition of tumor growth and metastasis was determined. Materials and Methods: With online bioinformatics tools, a fragment of the VEGF-A was selected for a peptide-based vaccine...

Objective: The purpose of this study was to investigate effect of plasma-derived exosomes of refractory/relapsed or responsive diffuse large B-cell lymphoma (DLBCL) patients on natural killer (NK) cell functions. Materials and Methods: In this cross-sectional and experimental study, NK cells were purified from responsive patients (n=10) or refractory/relapsed patients (n=12) and healthy donors (n=12). NK cells were treated with plasma-derived exosomes of responsive or refractory/relapsed patients...

Toxoplasma gondii (T. gondii) is prevalent intracellular parasite and a cause of worldwide infection in the human population. An inhibitory effect of this parasite on cancer growth has been demonstrated in cell culture and animal models. To determine whether the anticancer activities of T. gondii are associated with host immune response, in the current study the reactivity of anti- T. gondii antiserum with the surface of cancer cell lines was investigated. Anti- T. gondii antibodies were raised in rabbit and the reaction of this antiserum in comparison with other anti-parasite antisera (anti- T...

Background and Objectives: Endoscopic drainage/debridement of symptomatic walled off necrosis (WON) using lumen-apposing metal stents (LAMS) is both safe and effective. While endoscopic management of WON is the standard approach to treatment, the ideal concomitant medical therapy remains unclear. The purpose of this study was to further elucidate the effect of proton pump inhibitor (PPIs) therapy on the technical and clinical success of endoscopic treatment of WON. Methods: Two hundred and seventy-two patients in 8 centers with WON managed by endoscopic drainage using LAMS were evaluated...

BACKGROUND: The safety profile of bariatric surgery in patients with class I obesity, or body mass index ≥30 and <35 kg/m2 , is a matter of concern among patients and physicians. OBJECTIVE: To assess the safety profile of bariatric surgery in patients with class I obesity. SETTING: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data set. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 to 2016 data sets were queried for class I obesity patients who underwent primary bariatric procedures...

OBJECTIVE: Compare the outcome of spinal deformity correction between Ti-Ti and CrCo-Ti rods for the treatment of spinal Adolescent Idiopathic Scoliosis (AIS) using rods mentioned with all pedicle screws and translation technique. METHOD: 59 patients operated for spinal deformity (Lenke 1 or 2) AIS. The patients were divided into two groups by random allocation using Ti-Ti rods (n = 29) and CrCo-Ti rods (n = 30) and the alone difference among them in the surgical procedure was rod material (Ti-Ti or CrCo-Ti rods) and finally, radiological outcomes were compared preoperatively, postoperatively and at last follow-up for 12 months...

Introduction: Anterior cervical discectomy and fusion (ACDF) surgery is an accepted method for many spinal cord abnormalities. The purpose of this study was to evaluate the outcomes of treating patients with spinal cord lesions at one level or two levels through ACDF with cage-stand-alone (ACDF-CA) and ACDF with cage-with-plate fixation (ACDF-CP) surgery and comparing these results with each other. Methods: In this prospective, cross-sectional, descriptive study, eighty patients undergoing ACDF surgery were enrolled according to the inclusion and exclusion criteria...

PURPOSE: High-energy tibial fractures may cause compartment syndrome, which needs fasciotomy. However, in this procedure, close fractures become an open wound and choosing the best type of fixation for this situation has been a problem. We assumed early open reduction and internal fixation (ORIF) instead of late internal fixation or external fixation, or stage-based approach is a better method. METHODS: We collected fifty-seven medical records from 2012 to 2017 stored in Alzahra and Kashani University Hospital databases...

Background: The purpose of this study is to report outcomes of total hip arthroplasty (THA) in patients under the age of 35 years regarding pain and joint function. Materials and Methods: This preliminary analytic-descriptive study was performed in prospective consecutive series of forty-three patients younger than 35 years old who had undergone unilateral THA during a 36-month period. As the primary outcome, the severity of pain using visual analog scale (VAS) of 1-10, and as the secondary outcomes, joint range of motion (ROM) and the Harris Hip Score (HHS) were assessed in the preoperative visit, 1, 6, and 18 months after operation for each patient...

Background: Comminuted fractures happen frequently due to traumas. Fixation without opening the fracture site, known as minimally invasive plate osteosynthesis (MIPO), has recently become prevalent. This study has been designed to assess the outcomes of this treatment for tibial and femoral comminuted fractures. Methods: A total of 60 patients with comminuted femoral or tibial fractures were operated with MIPO method in this cross-sectional study at Alzahra university hospital in 2015...

Cocamidopropyl betaine (CAPB) is a zwitterionic surfactant that is synthesized using coconut oil and usually supplied in form of an aqueous solution with 25-37% w/w. In this study, a novel method based on UV-visible spectroscopy is developed for an accurate determination of CAPB synthesized from coconut oil. Eriochrome Black T (EBT) as a specific color indicator was added to CAPB and a red shift and color change were observed. This shift leads in increasing wavelength selectivity of the method. The change in the color intensity depends on the concentration of CAPB...

OBJECTIVE: To construct and validate a scoring system for evidence-based selection of bariatric and metabolic surgery procedures according to severity of type 2 diabetes (T2DM). BACKGROUND: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) account for >95% of bariatric procedures in United States in patients with T2DM. To date, there is no validated model to guide procedure selection based on long-term glucose control in patients with T2DM. METHODS: A total of 659 patients with T2DM who underwent RYGB and SG at an academic center in the United States and had a minimum 5-year follow-up (2005-2011) were analyzed to generate the model...
