Iatrogenic Laryngotracheal Stenosis in Children: a Case Report

Laryngotracheal stenosis is one of the important causes of pediatric airway obstruction, and the etiology can be classified as congenital and acquired. With the widespread use of tracheal intubation and tracheotomy in pediatric emergency, iatrogenic laryngotracheal stenosis is gradually replacing trauma and infection as the major cause of acquired laryngotracheal stenosis [1]. Nowadays, open surgery is the first choice for severe laryngotracheal stenosis cases [1,2]. Here, we describe a case of childhood iatrogenic severe laryngotracheal stenosis, and the reflection on the current treatment methods of children with laryngotracheal stenosis.

Case Reports: Hepatic Sclerosing Hemangioma: A Diagnostic Dilemma!

Haemangiomas are the most common benign incidentally detected hepatic lesions with a prevalence of ~20%. Most of them have typical imaging features and are easily diagnosed on triple phase studies. These are capillary, flash and giant hemangioma. Another subset of haemangiomas are Sclerosing hemangiomas or atypical haemangioma; these are sclerosed, thrombosed and/or hyalinised due to which these are heterogenous and show varied appearance making them difficult to diagnose.

Homology Modelled Structure of Glutaredoxin 2 from Chlamydomonas reinhardtii

Different types of Glutaredoxins (GRXs) that play a major role in cellular anti-oxidative reactions have been studied for their structure and function from various organisms. Glutathione (GSH), an anti-oxidant with several medical benefits, binds to GRXs. This work has structurally characterized GRX2 from C. reinhardtii (CrGRX2) using biophysical, molecular modelling, and isothermal titration calorimetry (ITC) techniques. CrGRX2 adopts the classical GRX-Trx fold consisting of five β-strands surrounded by four α-helices that bind to GSH with moderate strength through a cysteine residue. The residues involved in the interaction closely match with those observed for E. coli and human counterparts, indicating that the cellular GSH-GRXs antioxidant system is highly conserved.

Rapid Hydrogenation of Toluene in a One-Pass Reactor at Ambient Temperature and Pressure on a Novel Nanostructured Super-Alloy Catalysts without Containing Noble Metals

Novel Ni-Re super-alloy catalyst system is found for rapid hydrogenation of toluene to methylcyclohexane (MCH) in a one-pass reactor under mild reaction conditions. The novel bimetallic Ni-Re alloy catalysts exhibit the remarkably enhanced activity and stability for hydrogenation of toluene by comparison with monometallic Ni catalyst. The catalytic performance of novel Ni-Re catalyst is compared with that of Pt catalysts for hydrogenation of toluene. The better activity maintenance of the Ni-Re catalysts than the Pt-based catalysts are found. The alloying effect of Ni with Re is identified by XRD and EXAFS measurements.

Ordered Growth of Anodic Aluminum Oxide in Galvanostatic and Galvanostatic-Potentiostatic Modes

The results are presented of obtaining anodic aluminum oxide with an ordered pore arrangement by employing two anodizing modes - galvanostatic mode and combined (galvanostatic + potentiostatic) mode, at high values of the current density and voltage. Use has been made of an oxalate electrolyte and a complex electrolyte comprising oxalic acid and phosphoric acid. Scanning electron microscopy has been used to investigate the surface morphology of the barrier and porous layers and to determine pore sizes and inter-pore distance.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.

Synthesis of BaTiO3 Nanowires via Anodic Aluminum Oxide Template Method Assisted by Vacuum-and-Drop Loading

In this paper, we report on the synthesis of BaTiO3 nanowires via the anodic aluminum oxide template method. To fill in the precursors of BaTiO3 into anodic aluminum oxide templates, the vacuum and drop loading method developed in our previous study was used. Ba(CH3COO)2 (barium acetate) and C12H28O4Ti (tetraisopropyl orthotitanate) were used as Ba and Ti sources, respectively. Anodic aluminum oxide membranes with the through-hole diameter of ~200 nm were used as the template for BaTiO3 nanowires.
