PURPOSE: Therapy of severe pneumonia is very challenging in view of the current widespread bacterial resistance to many antibiotics especially extended spectrum ß-lactams, carbapenems, and anti-pseudomonal drugs. The current study aimed at assessing antimicrobial sensitivity pattern and optimization of the antibiotic stewardship program applied in a university affiliated pediatric intensive care unit (PICU). SUBJECTS AND METHODS: This prospective cohort study included all patients aged 1 month to 12 years, admitted to the PICU with severe pneumonia episodes indicated for mechanical ventilation, and were followed up and investigated...

PURPOSE: The marginal fit is an essential component for the clinical success of prosthodontic restorations. The aim of this study was to investigate the influence of different abutment finish line widths and crown thicknesses on the marginal fit of zirconia crowns fabricated using either standard or fast sintering protocols. MATERIALS AND METHODS: Six titanium abutments were fabricated for receiving zirconia molar crowns. Crowns were designed virtually and milled from partially sintered zirconia blanks and divided into 12 groups (n = 10/group)...

Heat stress threatens agriculture worldwide. Plants acquire heat stress tolerance through priming, which establishes stress memory during mild or severe transient heat stress. Such induced thermotolerance restructures metabolic networks and helps maintain metabolic homeostasis under heat stress. Here, we used an electrospray ionization mass spectrometry-based platform to explore the composition and dynamics of the metabolome of Arabidopsis thaliana under heat stress and identify metabolites involved in thermopriming...

In this study, physico-chemical properties, fatty acid composition, and tocopherol contents of several walnut kernel oils obtained through cold-press and Soxhlet extractions were investigated. The acidity, peroxide, and unsaponifiable matter of oil samples extracted in the Soxhlet system were found higher. Total phenol contents of the oils obtained in cold press and Soxhlet extraction systems were 121.9 mg GAE/100g (Kaman-2) and 154.6 mg GAE/ 100g (Büyükoba), and between 135.9 mg GAE/100g (Kaman-2) and 163...

OBJECTIVE: To evaluate the role of β-HCG level changes between days 0 and 1 as an early predictor of methotrexate success in cases of tubal ectopic pregnancy. METHODS: A retrospective study included 86 tubal ectopic pregnancies treated with a single-dose methotrexate protocol of 50 mg/m2 of body surface. β-HCG measurements were taken on days 0, 1, 4 and 7 where day 0 is the day of methotrexate injection. Day 0 β-HCG and the percentage change in β-HCG level between days 0 and 1 (HCG index) were calculated and compared between patients who were successfully or unsuccessfully treated...

This study was conducted to investigate the impacts of microwave heating treatments at different powers (0, 180, 360, 540, 720 and 900Watts) on the quality attributes of chia seed oil. Linoleic acid contents of the chia seed oil heated in microwave oven changed between 19.21% (900 W) and 21.17% (control), respectively (p < 0.05). Linolenic acid contents of heated chia seed oils varied between 66.84% (900 W) and 68.71% (control). α-Tocopherol and β-tocopherol contents of the chia oil samples varied between 47...

Background: Hypercoagulability can lead to serious thromboembolic events. The aim of this study was to assess the perioperative coagulation status in liver transplant recipients with a tendency to hypercoagulability. Methods: In a prospective observational study (South African Cochrane Registry 201405000814129), 151 potential liver transplant recipients were screened for thrombophilic factors from October 2014 to June 2017, and 57 potential recipients fulfilled the inclusion criterion of presenting two or more of the following thrombophilic factors: low protein C, low protein S, low anti-thrombin, increased homocystein, increased antiphospholipid IgG/IgM antibodies, increased lupus anticoagulant, and positive Factor V Leiden mutation...

Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) systems are key immune mechanisms helping prokaryotic species fend off RNA and DNA viruses. CRISPR/Cas9 has broad applications in basic research and biotechnology and has been widely used across eukaryotic species for genome engineering and functional analysis of genes. The recently developed CRISPR/Cas13 systems target RNA rather than DNA and thus offer new potential for transcriptome engineering and combatting RNA viruses...

During the 2016/2017 winter season, we isolated 33 highly pathogenic avian influenza viruses (HPAIVs) of H5N6 subtype and three low pathogenic avian influenza viruses (LPAIVs) from debilitated or dead wild birds, duck feces, and environmental water samples collected in the Izumi plain, an overwintering site for migratory birds in Japan. Genetic analyses of the H5N6 HPAIV isolates revealed previously unreported phylogenetic variations in the PB2, PB1, PA, and NS gene segments and allowed us to propose two novel genotypes for the contemporary H5N6 HPAIVs...

Catharanthus roseus is a perennial herb known for the production of important terpenoid indole alkaloids (TIAs) in addition to a variety of phenolic compounds. The goal of the present work was to detect the prolonged effects of MeJA (6 uM) treatment across time (up to 24 days) in order to detect the stepwise response of MeJA-induced genes and pathways in leaves of C. rouses. Prolonged exposure of plants to MeJA (6 uM) treatment for different time points (6, 12 and 24 days) indicated that genes in the indole alkaloid biosynthesis pathway and upstream pathways were triggered earlier (e...

Vardenafil hydrochloride is commonly used for the curing of erectile dysfunction. VAR suffers certain limitations: (i) short elimination half-life (4-5 h), (ii) low aqueous solubility (0.11 mg/mL), (iii) susceptibility to extensive first-pass metabolism and drug efflux transporters (P-glycoprotein), and (iv) limited (15%) oral bioavailability. The current study focused on the development of VAR lipomers as promising modified release systems able to enhance oral bioavailability. VAR-lipomers (lipid-polymer complexes) were successfully developed by a modified precipitation technique employing a lipid (polyglyceryl-6-distearate or glyceryl tristearate) and an amphiphilic polymer (Gantrez®)...

Valproate is a widely used drug against epilepsy and several other neurological disorders although it has deleterious hepatotoxic side effects. The current study was designed to test if agmatine as nitric oxide modulator has protective effects against valproate-induced hepatic injury. Male Swiss albino mice were treated with sodium valproate (SVP) with or without agmatine for 7 days. Serum and liver samples were collected for analysis. Results have revealed that agmatine exerted hepatoprotective effects against SVP-associated hepatic injury...

Background: Plants of the Amaryllidaceae family have been under intense scrutiny for the presence of a couple of alkaloidal secondary metabolites with endued cytotoxic activity, such as pancratistatin ( 1 ), 7-deoxypancratistatin ( 2 ), narciclasine ( 3 ), 7-deoxynarciclasine ( 4 ), trans -dihydronarciclasine ( 5 ), and 7-deoxy- trans -dihydronarciclasine ( 6 ). Nevertheless, preclinical evaluation of these alkaloids has been put on hold because of the limited quantity of materials available from isolation...

Background There is a need for safe, effective treatment for atopic dermatitis (AD) in the Middle East. Objective To propose a practical algorithm for the treatment of AD throughout the Middle East. Methods An international panel of six experts from the Middle East and one from Europe developed the algorithm. The practical treatment guide was based on a review of published guidelines on AD, an evaluation of relevant literature published up to August 2016 and local treatment practices. Results Patients with an acute mild-to-moderate disease flare on sensitive body areas should apply the topical calcineurin inhibitor (TCI), pimecrolimus 1% cream twice daily until clearance...

BACKGROUND: As survival rates for children with acute lymphoblastic leukemia (ALL) improve, awareness of treatment complications becomes important. Osteonecrosis (ON) is a serious disabling complication in treated ALL patients. The aim of the study was to define the frequency of ON identified by magnetic resonance imaging (MRI) and to study the risk factors for ON. PATIENTS AND METHODS: The frequency of ON was evaluated retrospectively in 858 patients with ALL who were diagnosed at Children's Cancer Hospital of Egypt from January 2009 to December 2012...
