BACKGROUND: To study the anti-edematous, anti-inflammatory, and neuroprotective effect of etanercept in the model of experimental head injury. METHODS: In this study, 40 male-adult Spraque-Dawley rats, with weight ranging from 250g to 300g, were used. The rats are divided into groups as control; non-penetrating trauma; trauma +NS; post-traumatic normal saline; trauma + D; post-traumatic dexamethasone and trauma + E. All medicines were given into peritoneum. After applying trauma and medicine, rats were decapitated in the 24th hour and the samples were studied histopathologically...

BACKGROUND: Bendamustine, an N-mustard-benzoimidazole hybrid conjugate, was recently approved for the treatment of chronic lymphocytic leukemia. However, the short half-life of bendamustine may limit its clinical applications. OBJECTIVE: The purpose of this study is to design and synthesize compounds with a more favorable pharmacokinetic profile. METHODS: We synthesized a series of hybrid molecules comprising a phenyl N-mustard moiety and benzothiazole or benzimidazole scaffold linked via an ureido linker and evaluated their antitumor activity and plasma stability...

The distinction of thyroid carcinoma from benign thyroid neoplasm, as well as the subtyping of papillary carcinoma (PC) and follicular carcinoma (FC), may be performed histopathologically in the majority of cases. However, in certain cases, it is difficult to histopathologically distinguish between PC and FC, as well as follicular adenoma (FA), FC and the dominant nodule of multinodular goiter (MNG-DN). The present study aimed to determine the roles of the expression levels of the tight junction proteins claudin 1, 4 and 7 in the differential diagnosis of PC, FC, FA, MNG-DN, medullary carcinoma (MC) and anaplastic carcinoma (AC)...

Three series of aza-artemisinin derivatives were synthesized for studies of anticancer activity. The first series of compounds were prepared via copper(I)-catalyzed azide alkyne cycloaddition, so called "click reaction", starting from propargyl derivatives of 11-aza-artemisinin and various azides, whereas the second and third series of compounds were prepared by triazolization reaction starting from enolizable ketones and primary amines connected to artemisinin. In vitro studies of the 23 synthesized artemisinin derivatives unveiled that 9 compounds displayed antiproliferative activity in the low micromolar range, with 5d being the most promising compound showing 50% inhibition of Cem and HeLa cell growth at 0...

BACKGROUND: Thoracic paravertebral block can provide analgesia for unilateral chest surgery and is associated with a low complication rate. Horner syndrome also referred to as oculosympathetic paresis, is a classic neurologic constellation of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis resulting from disruption of the sympathetic pathway supplying the head, eye, and neck. CASE REPORT: We present a patient with an ipsilateral transient Horner syndrome after ultrasound guided single shot of 15mL 0...

Background Arthrosis of the knee is a common problem in Germany that is often treated with arthroplasty. To support the orthopaedic surgeon, person-matched instruments (PMI) are available from several providers. In this study we investigated the clinical and radiological outcome of the use of the PMI Visionaire(™) (Smith&Nephew). Furthermore, we investigated the influence of operative experience of the orthopaedic surgeon on the clinical and radiological results. Time in the operating room (OR) was identified as a parameter for cost effectiveness even during training to become an orthopaedic surgeon...

AIM: High fraction of scattered radiation in cone-beam CT (CBCT) imaging degrades CT number accuracy and visualization of low contrast objects. To suppress scatter in CBCT projections, we developed a focused, two-dimensional antiscatter grid (2DASG) prototype. In this work, we report on the primary and scatter transmission characteristics of the 2DASG prototype aimed for linac mounted, offset detector geometry CBCT systems in radiation therapy, and compared its performance to a conventional one-dimensional ASG (1DASG)...

Root canal therapy (RCT) is a common and successful treatment for irreversible pulpitis due to carious pulp exposure in mature permanent teeth. However, it is often an expensive procedure, may require multiple appointments, and requires a high level of training and clinical skill, specifically in molars. Uninsured patients, low-income patients, and patients with limited access to specialist care often elect for extraction of restorable teeth with irreversible pulpitis. There is a need for an alternative affordable treatment option to preserve their teeth and maintain chewing function...

INTRODUCTION: The present study evaluated the element distribution in completely set calcium-enriched mixture (CEM) cement after application of 35% carbamide peroxide, 40% hydrogen peroxide and sodium perborate as commercial bleaching agents using an energy-dispersive x-ray microanalysis (EDX) system. The surface structure was also observed using the scanning electron microscope (SEM). METHODS AND MATERIALS: Twenty completely set CEM cement samples, measuring 4×4 mm(2), were prepared in the present in vitro study and randomly divided into 4 groups based on the preparation technique as follows: the control group; 35% carbamide peroxide group in contact for 30-60 min for 4 times; 40% hydrogen peroxide group with contact time of 15-20 min for 3 times; and sodium perborate group, where the powder and liquid were mixed and placed on CEM cement surface 4 times...

INTRODUCTION: Cold Knife Conization (CKC) is one of the most effective methods for the treatment of Cervical Intraepithelial Neoplasia (CIN). Some studies showed a relation between preterm birth and the treatment of CIN; on the other hand, other studies do not show such a relationship. AIM: The present study was conducted with the aim to investigate the pregnancy outcomes of Turkish women regarding demographic characteristics, obstetric history, removed tissue, and residual cervical length after CKC and to determine the effect of removed cervical tissue volume and height on preterm birth...

In the present work a novel heterogeneous cation exchange membrane (CEM) composed of poly vinyl chloride (PVC) and 2-acrylamido-2-methylpropane sulfonic acid based hydrogel (AMAH) was prepared. The membranes were fabricated with different fractions of AMAH to optimize the performance in desalination. The hydrogel was characterized by FT-IR to prove the successful synthesis. The membrane properties such as permselectivity, ionic permeability, flux, water content, electrical resistance, morphology, contact angle and dimensional stability were evaluated...

INTRODUCTION: HIV viral envelope proteins are targets for small inhibitor molecules aimed at disrupting the cellular entry process. Potential peptide-class inhibitor molecules (rDNA drugs) have been previously identified, with mixed results, through biomimicry and phage display experimental methods. Here we describe a new approach based on computational fragment discovery. The method has the potential to not only optimize peptide binding affinity but also to rapidly produce alternative inhibitors against mutated strains...

Despite the extensive work on pathological mechanisms and some recent advances in the treatment of different hematological malignancies, leukemia continues to present a significant challenge being frequently considered as incurable disease. Therefore, the development of novel therapeutic agents with high efficacy and low toxicity is urgently needed to improve the overall survival rate of patients. In this comprehensive review article, the current knowledge about the anticancer activities of flavonoids as plant secondary polyphenolic metabolites in the most commonly used human established leukemia cell lines (HL-60, NB4, KG1a, U937, THP-1, K562, Jurkat, CCRF- CEM, MOLT-3, and MOLT-4) is compiled, revealing clear anti-proliferative, pro-apoptotic, cell cycle arresting, and differentiation inducing effects for certain compounds...

BACKGROUND: Immediate or early loading of dental implants becomes a clinically feasible concept. PURPOSE: The aim was to evaluate the effects of different loading protocols (immediate, early, and delayed) on secondary stability and peri-implant bone density of single implants in the posterior maxilla. MATERIALS AND METHODS: Thirty-nine implants (Dentium, South-Korea) were placed in 39 patients. After placement, implant stability values (ISQ) and baseline peri-implant bone density values derived from cone-beam computed tomography were recorded...
