In this study, we intend to find the laminate condition for improvement of the chemical resistance of the aluminum pouch film widely used as the coating material of the secondary battery. Here, we investigated the properties including the initial adhesive strength and electrolyte resistance between the metal film layer aluminum and the sealant layer cast polypropylene (CPP) film. As for the laminating condition, we changed the temperature and line speed and maintained the identical pressure conditions. A roll-to-roll dry laminate coating system was used in surface treatment agent coating, adhesive coating, and film laminate...

We pioneer a versatile surface modification strategy based on mussel inspired oxidative catecholamine polymerization for the design of nitroxide containing thin polymer films. A 3,4-dihydroxy-L-phenylalanine (L-DOPA) monomer equipped with a 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) derived oxidation-labile hydroxylamine functional group is employed as a universal coating agent to generate polymer scaffolds with persistent radical character. Various types of materials including silicon, titanium, ceramic alumina and inert poly(tetrafluoroethylene) (PTFE) were successfully coated with poly(DOPA-TEMPO) thin films in a one-step dip-coating procedure under aerobic, slightly alkaline (pH 8...

Ornithine Decarboxylase (ODC) is an enzyme that initiates polyamine synthesis in human. Polyamines play key roles in cell-cell adhesion, cell motility and Cell cycle regulation. Higher synthesis of polyamines also occurs in rapidly proliferating cancer cells are mediated by ODC. As per earlier studies, Di-Flouro Methyl Orninthine (DFMO) is a proven efficient inhibitor ODC targeting the catalytic activity, however, its usage is limited due to side effects. Targeting ODC is considered as a potential therapeutic modality in the treatment of cancer...

Current implant materials have widespread clinical applications together with some disadvantages, the majority of which are easily to induce infection and hardly to exhibit biocompatibility. To efficiently improve their properties, the development of interface multifunctional modification in a simple, universal and environment benign approach becomes a critical challenge and appeals numerous attention of scientists. In this study, a lysozyme-polyphosphate composite coating was fabricated for titanium(Ti)-based biomaterial in order to obtain multifunctional surface...

BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard surgical treatment for benign gallbladder disease. Nevertheless, conversion to open cholecystectomy (OC) is needed in some cases. The aim of this study is to calculate our institutional conversion rate and to identify the variables that are implicated in increasing the risk of conversion (LC-OC). MATERIALS AND METHODS: We carried out a retrospective study of all cases of LC performed at the American University of Beirut Medical Center between 2000 and 2015...

The relationship between wear resistance and filler size or filler loading was clarified for the universal resin composite; however, their relationship in flowable resin composites has not been clarified. The purpose of this study was to investigate the effect of filler size and filler loading on wear of experimental flowable resin composites by using a cyclic loading device. Nine experimental flowable resin composites consisting of three different sizes (70, 200 and 400 nm) and loading (50, 55 and 60 wt%) of filler were prepared...

OBJECTIVES: Universal adhesives have been recently introduced for use as self-etch or etch-and-rinse adhesives depending on the dental substrate and clinical condition. However, their bonding effectiveness to laser-irradiated dentin is still not well known. Therefore, the aim of this study was to compare the shear bond strength (SBS) of two universal adhesives (Single Bond Universal, Nova Compo-B Plus) applied following laser-etching with SBS of the same adhesives applied in self-etch and acid-etch modes, respectively...

Professor Zofia Umiastowska Sawicka laid the foundations for modern pediatric surgery in Poland, first in Bialystok, and subsequently in Kielce. She was a student of Prof. Jan Kossakowski from Warsaw Medical University to be counted among his most talented and skilled disciples. Professor Umiastowska became the head of the first Department of Pediatric Surgery in Bialystok, which was later incorporated into the Medical Academy of Bialystok. In 1977 she moved to Kielce to run the Department of Pediatric Surgery until her retirement in 1991...

The purpose of this study was to investigate the expression of intercellular adhesion molecule-1 (ICAM-1) in umbilical vascular of pregnant women with gestational diabetes mellitus (GDM) and the clinical significance. A total of 103 pregnant women with GDM were selected in the First Hospital of Lanzhou University and the Second Affiliated Hospital of Xi'an Jiaotong University from January 2016 to December 2016 as GDM group. At the same time, 106 normal pregnant women were selected as control group. i) General information of the two groups of pregnant women including age, gestational age, gravida, parity, BMI, systolic blood pressure and diastolic blood pressure were compared; ii) the laboratory indicators of the two groups of pregnant women including fasting blood glucose, glycosylated hemoglobin (HbA1c), umbilical cord arterial pH, partial pressure of oxygen (pO2) and carbon dioxide (pCO2) in umbilical artery were compared; iii) expression of ICAM-1 in umbilical vascular was detected by immunohistochemistry; iv) expression levels of ICAM-1 in umbilical vascular of the two groups of patients were compared...

INTRODUCTION: After root canal treatment, the dentin-sealer interface undergoes degradation, allowing for interfacial microbial biofilm proliferation and treatment failure. Saliva and cariogenic bacteria showed esteraselike activities (ie, cholesterol esterase [CE]-like and/or pseudocholinesterase [PCE]-like) that degrade methacrylate-based resin materials and/or the restoration-tooth interface, increasing microbial interfacial proliferation. Enterococcus faecalis is a gram-positive bacterium that is commonly detected in persistent endodontic infections...

OBJECTIVE: Ischemia-reperfusion (I/R) injury is a major clinical problem linked to vascular surgery. Currently, no drugs to prevent or to treat I/R injury are approved for clinical use. C1 inhibitor (C1 INH) is known to reduce activation of the plasma cascade systems that are involved in the pathophysiologic process of I/R injury. The aim of this study was therefore to investigate the effect of C1 INH on complement deposition and endothelial cell activation in a rat model of hind limb I/R injury...

Water flux and durability are the two critical parameters that closely associated with the practical application of membrane distillation (MD). Herein, we report a facile approach to fabricate superhydrophobic polyimide nanofibrous membranes (PI NFMs) with hierarchical structures, interconnected pores and high porosity, which was derived from the electrospinning, dual-bioinspired design and fluorination processes. Bio-inspired adhesive based on polydopamine/polyethyleneimine (PDA/PEI) composite was firstly linked onto membrane substrates, and then assembled lotus leaf hierarchical structure by binding the negatively charged silica nanoparticles (SiO2 NPs) via electrostatic attraction...

OBJECTIVES: The aim of this study was to test long-term microtensile bond strength (µTBS) of 2 universal adhesives applied to dentin following "total-etch" (TE) or "self-etch" (SE) protocols and aged by direct or indirect water exposure using simulated pulpal pressure. MATERIALS AND METHODS: Single Bond Universal (SBU, 3M ESPE) or Ipera Bond (IP, Itena) were applied to mid-coronal dentin ("flat dentin") or Class I cavity ("cavity dentin") following TE or SE protocols in 112 extracted human third molars...

This study evaluated the simulated localized wear of resin luting cements for universal adhesive systems using different curing modes. Five resin luting cements for universal adhesive systems were evaluated and subsequently subjected to wear challenge in a Leinfelder-Suzuki wear simulation device. Overall, 20 specimens from each resin luting cement were photo-cured for 40 s (dual-cure group), and 20 specimens of each material were not photo-cured (chemical-cure group). Simulated localized wear was generated using a stainless steel ball-bearing antagonist in water slurry of polymethylmethacrylate beads...
