Fracture Resistance of Anterior Teeth Restored with Post-retained Ceramic Crown vs Ceramic Endocrowns.

Aim: To compare the fracture resistance of anterior teeth restored with either glass fiber post (GFP) and conventional lithium disilicate (LDS) crowns or endocrowns made of LDS or hybrid ceramics.

Materials And Methods: A total of 21 central incisors with 2-mm ferrule and 1-mm shoulder finish line were applied in this investigation. The teeth were divided into three main groups ( = 7) according to the type of restoration used: PC glass fiber post (GFP) and e-max crown, EE (LDS endocrown), and VE (Vita-Enamic endocrown).

Imaging features of the renal lymphoma: case report and literature review.

Renal affection is common in disseminated non-Hodgkin's lymphoma (NHL) which is known as secondary renal lymphoma (SRL). Primary renal lymphoma (PRL) is an exceedingly uncommon disease, which accounts for less than 1% of all renal masses. Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of NHL in both primary as well as secondary renal lymphomas.

Using Rosemary Essential Oil as a Potential Natural Preservative during Stirred-like Yogurt Making.

The popularity of rosemary has grown as a natural alternative over the synthetic supplements due to its potential health benefits. The rosemary plant has been utilized to preserve food due to its ability to prevent oxidation and microbial contamination. The reason for this study was to determine the phytochemical components and antimicrobial activity of rosemary essential oil (REO) and the effect of REO addition (0.

Congenital High Airway Obstruction Syndrome (CHAOS): No Intervention, No Survival-A Case Report and Literature Review.

Congenital high airway obstruction syndrome (CHAOS) is complete or partial obstruction of the fetal upper airway. CHAOS is a rare and fatal condition if no perinatal intervention is done. Antenatal sonographic imaging has typical findings that can help in an early diagnosis, which is important in deciding elective termination of the pregnancy or successful planning of appropriate perinatal management.

Combined phacoemulsification and viscocanalostomy with Ologen implant versus combined phacoemulsification and viscocanalostomy.

Background: To study the efficacy of the biodegradable collagen implant Ologen® as an adjuvant in phaco-viscocanalostomy in patients with coexisting cataract and primary open angle glaucoma.

Methods: This prospective, interventional, randomized clinical study was done at Alpha Vision Center, Zagazig, Egypt. Patients with coexisting cataract and glaucoma were randomized to receive either phaco-viscocanalostomy (Phacovisco group) (39 eyes) or phaco-viscocanalostomy with Ologen® implant (OloPhacovisco group) (40 eyes).

Effect of Metformin and Sitagliptin on Doxorubicin-Induced Cardiotoxicity in Rats: Impact of Oxidative Stress, Inflammation, and Apoptosis.

Doxorubicin (DOX) is a widely used antineoplastic drug whose efficacy is limited by its cardiotoxicity. The aim of this study was to investigate the possible protective role of the antidiabetic drugs metformin (250 mg/kg dissolved in DW p.o.

CspE is Overproduced by Temperature Downshift in the Acinetobacter johnsonii DBP-3.

The denitrifying bacterium Acinetobacter johnsonii strain DBP-3 which was capable of removing phosphate, nitrate, and ammoniacal salt is psychrotolerant, whereas, the cold shock response mechanisms or the cold shock proteins (Csps) was unclear. In this article, the optimal growth temperature (25 °C) and cold shock temperature (7.5 °C) were determined firstly by an Arrhenius plot of the growth of the strain DBP-3.

Significant hepatic expression of IL-2 and IL-8 in biliary atresia compared with other neonatal cholestatic disorders.

Objectives: Although the exact etiology of biliary atresia (BA) is still elusive, inflammation plays a key role. Release of proinflammatory cytokines from activated immune cells perpetuates the injury and causes biliary destruction. We aimed to study interleukin (IL)-2 and IL-8 expression in liver tissue of BA patients compared with other neonatal cholestatic disorders.

Assessment of the prognostic value of methylation status and expression levels of FHIT, GSTP1 and p16 in non-small cell lung cancer in Egyptian patients.

Background: Methylation of tumor suppressor genes has been investigated in all kinds of cancer. Tumor specific epigenetic alterations can be used as a molecular markers of malignancy, which can lead to better diagnosis, prognosis and therapy. Therefore, the aim of this study was to evaluate the association between gene hypermethylation and expression of fragile histidine triad (FHIT), glutathione S-transferase P1 (GSTP1) and p16 genes and various clinicopathologic characteristics in primary non-small cell lung carcinomas (NSCLC).

Nitro-aspirin is a potential therapy for non alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver injury; however its therapeutic strategy has not been established yet. Nitro-aspirin (NO-aspirin) is a new molecule in which aspirin and a NO-donating group are covalently linked. This study investigated the potential protective effect of NO-aspirin on NAFLD.

Carcinoma of the superior pulmonary sulcus: Results of multidisciplinary treatment.

Background: Superior sulcus tumors are a complex subset of tumors accounting for less than 5% of lung tumors.

Methods: Twenty-three patients admitted between 2001 and 2007 were included in the study,. Computed tomography scan of the chest was considered the primary diagnostic and staging investigation for all patients.

Four-point scleral fixation of posterior chamber intraocular lenses without scleral flaps.

Purpose: To report the visual results and complications of a new technique for scleral fixation of posterior chamber intraocular lenses (IOLs) without scleral flaps.

Methods: Half-thickness 3 mm scleral grooves 1 mm behind the limbus were constructed opposite to each other. The straight needle with a double-armed 10/0 prolene suture was introduced at one end of the scleral groove to exit through the corneal incision then passed through the two holes of the IOL.

Vasodilator mechanism of intermedin/adrenomedullin-2 in anesthetized rats.

We examined whether the vasodepressor effect of intermedin/adrenomedullin-2, a new member of the calcitonin gene-related peptide family, acted via activation of the nitric oxide/L-arginine pathway, the prostanoid pathway, or the opening of K+ channels. Intermedin/adrenomedullin-2 (0.3-30 nmol/kg) dose-dependently decreased mean arterial pressure (ED50 of 2.
