BACKGROUND: Antibacterial restorations can increase the success rate of minimum invasive dentistry especially in young permanent molars with deep carious lesions as an attempt to preserve maximum dental structure and avoid pulp exposure. Further research is warranted to evaluate different antibacterial agents. OBJECTIVES: This study aimed to evaluate the efficacy of adding chlorhexidine gluconate (CHX) or aqueous miswak (Salvadora persica) extract on the clinical performance and in vivo antibacterial activity of conventional anhydrous glass ionomer cement (GIC)...

The impact of post-synthesis processing in reduced graphene oxide materials for supercapacitor electrodes has been analyzed. A comparative study of vacuum, freeze and critical point drying was carried out for hydrothermally reduced graphene oxide demonstrating that the optimization of the specific surface area and preservation of the porous network are critical to maximize its supercapacitance performance. As described below, using a supercritical fluid as the drying medium, unprecedented values of the specific surface area (364 m(2) g(-1)) and supercapacitance (441 F g(-1)) for this class of materials have been achieved...

Delays in the discharge of hospital patients cause a backlog for new admissions from the Emergency Departments (ED), outpatient clinics, and transfers from the Intensive Care Units (ICU). A variety of initiatives have been reported on previously which aim to tackle this problem with variable success. In this quality improvement project, we aimed to increase the proportion of discharged patients who leave the paediatric unit by 12:00 Noon from 7% to 30% by May 2015. A baseline discharge process map was studied to understand the possible causes of the delays...

The MmpL family of proteins translocates complex (glyco)lipids and siderophores across the cell envelope of mycobacteria and closely related Corynebacteriaceae and plays important roles in the biogenesis of the outer membrane of these organisms. Despite their significance in the physiology and virulence of Mycobacterium tuberculosis, and from the perspective of developing novel antituberculosis agents, little is known about their structure and mechanism of translocation. In this study, the essential mycobacterial mycolic acid transporter, MmpL3, and its orthologue in Corynebacterium glutamicum, CmpL1, were investigated as prototypical MmpL proteins to gain insight into the transmembrane topology, tertiary and quaternary structures, and functional regions of this transporter family...

BACKGROUND: Several studies have raised concerns that future demand for blood products may not be met. The ageing of the general population and the fact that a large proportion of blood products is transfused to elderly patients has been identified as an important driver of blood shortages. The aim of this study was to collect, for the first time, nationally representative data regarding blood donors and transfusion recipients in order to predict the future evolution of blood donations and red blood cell (RBC) use in Switzerland between 2014 and 2035...

Currently, the outcomes of conventional chemotherapeutic approaches are unsatisfactory. Clinical application of nanoparticles seems promising. We aim to evaluate the possible antitumor activity of zinc oxide nanoparticles (ZnONPs) as a chemotherapeutic approach in in vitro and in vivo experimental models. An in vitro study was performed on three different cell lines, namely human hepatocellular carcinoma (HEPG2), human prostate cancer (PC3), and none-small cell lung cancer (A549) cell lines. An in vivo study using diethylnitrosamine (DENA)-induced HCC in adult male Wistar rats was conducted to investigate the potential antitumor activity of ZnONPs in HCC and the possible underlying mechanisms...

INTRODUCTION: Lipoid pneumonia is a clinical condition that may be initially asymptomatic or confused with an infectious or malignant lung disease. OBJECTIVES: We report four cases of this pathological condition. METHODS: The first case concerned an 85-year old woman with bilateral confluent pulmonary opacities, ground-glass type. Diagnosis was based on the cytology of the bronchoalveolar lavage (BAL) fluid followed by its ultrastructural examination...

The use of Cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenator (ECMO) in patients suffering from Sickle cell disease (SCD) needs specific precautions. Whereas, no consensual protocols have been established to clarify therapeutic management. CASE REPORT A 7-year-old boy was admitted to the hospital for surgery of advanced endocarditis.  Major dyspnea, hemodynamic distress and fever were noted on physical examination. Biological tests exploring anaemia revealed Haemoglobin (Hb) S levels of 39...

BACKGROUND: Moderate sedation for gastrointestinal endoscopy has traditionally been provided by the endoscopist. Controversy has ensued over safe and efficient sedation practice as endoscopy has increased in numbers and complexity. AIM: To evaluate the safety of ketamine sedation given by non-anesthesiologist during gastrointestinal endoscopy in children. METHODS: A prospective study of 100 paediatric patients with gastrointestinal symptoms who were a candidate for upper or lower gastrointestinal endoscopy in paediatric endoscopy unit at Abo El-Reesh Paediatric Hospital, Cairo University...

Cordia boissieri A. DC. (Boraginaceae) is traditionally used as an herbal remedy for diabetes by Hispanic women in Southwestern USA. A recent investigation showed the significant protective effect of ethyl acetate extract against metabolic syndrome (MS). However, the corresponding active principles responsible for this effect and relations between their structure and biological actions remain unclear. Thus, ethyl acetate extract was subjected to column chromatography, which yielded seven compounds identified on the basis of spectroscopic data as rutin, hesperidin, kaempferol-3-O-β-d-glucopyranoside, rosmarinic acid, β-sitosterol-3-O-β-d-glucopyranoside, quercetin, and kaempferol...

We describe two children with oedematous malnutrition; one admitted to a nutrition unit in Uganda and another to a paediatric department in Denmark. Both children received nutritional therapy and recovered. Although oedematous malnutrition is rarely seen in industrialized countries, the condition has been associated with chronic diseases. It is a life-threatening condition, and the pathogenesis remains unknown. Specialized nutrition products have been developed for low-resource clinics in developing countries, however, no specific protocols or products are available for physicians in Denmark...

Apicomplexan parasites possess a unique cortical cytoskeleton structure composed of intermediate filaments. Its building blocks are provided by a conserved family of proteins named alveolins. The core alveolin structure is made up of tandem repeat sequences, thought to be responsible for the filamentous properties of these proteins. A subset of alveolins also possess conserved motifs composed of three closely spaced cysteine residues situated near the ends of the polypeptides. The roles of these cysteine motifs and their contribution to alveolin function remains poorly understood...

UNLABELLED: We conducted several aviary experiments to investigate the influence of colours in quantity judgments of two species of birds; house crow (Corvus splendens) and common myna (Acridotheres tristis). Different quantity (in seven different food proportions) of mealworms were presented nonsequentially to all birds using artificially coloured red mealworms, for experiment 1, and using artificially coloured green mealworms, for experiment 2. Both red and green coloured mealworms have no significant effect on house crow's quantity judgments (red: ANOVA: F6,30 = 1...

Radio-chemotherapy is a common treatment for locally advanced squamous cell head-and-neck cancers (LA-SCCHN). Cisplatin (100 mg/m(2)) every 3 weeks is very common but associated with considerable toxicity. Therefore, cisplatin programs with lower daily doses were introduced. There is a lack of studies comparing lower-dose programs. In this study, 85 patients receiving radio-chemotherapy with 20 mg/m(2) cisplatin on 5 days every 4 weeks (group A) were retrospectively compared to 85 patients receiving radio-chemotherapy with 30-40 mg/m(2) cisplatin weekly (group B)...
