UNLABELLED Changes, destructions and interruptions in middle ear ossicular chain architecture may be caused by infection, trauma, tumors, congenital alterations or prior surgeries. Nonetheless, infectious and inflammatory processes, focal or generalized which affect the middle ear are the most prevalent, causing a great demand for ossiculoplasty. Biosilicato is a new material which can be used ...

Back Cover: The image is a schematic representation of amyloid β1.40 fibrils, in which the important intrastrand contact Phe19–Leu34 modified to alter physical forces governing fibril formation. In this way, information on their influence fibrillation kinetics, morphology, structure, and dynamics as well toxicity can be obtained. article 2200489 by Benedikt Schwarze Daniel Huster reviews work d...

The aim of this research was to determine the chemical composition and insecticidal activity of the essential oils derived from flowering aerial parts of Artemisia giraldii Pamp. and A. subdigitata Mattf. (Family: Asteraceae) against the maize weevil (Sitophilus zeamais Motsch.). Essential oils of aerial parts of A. giraldii and A. subdigitata were obtained from hydrodistillation and investigat...

The aim of this research was to determine the chemical composition and insecticidal activity of the essential oil of Curcuma wenyujin Y.H. Chen et C. Ling rhizomes against the booklouse Liposcelis bostrychophila Badonnel and to isolate any insecticidal constituents from the essential oil. The essential oil of C. wenyujin rhizomes was obtained by hydrodistillation and analyzed by GC-MS. A total ...

Mosquitoes, such as Aedes aegypti and Anopheles gambiae, are important vectors of human diseases. Fluralaner, a recently introduced parasiticide, was evaluated as a mosquitocide in this study. On Ae. aegypti and An. gambiae fourth-instar larvae, fluralaner had 24-h LC50 (lethal concentration for 50% mortality) values of 1.8 ppb and 0.4 ppb, respectively. Following topical application to adult A...

Purpose: To investigate the chemical composition and toxicity of the essential oil of Glycosmis parviflora (Sims) Little aerial parts against root-knot nematode and two grain storage insects (maize weevil and red flour beetle). Methods: Steam distillation of G. parviflora was carried out using Clavenger apparatus in order to extract its volatile oil. Gas chromatography/mass spectrometric (GC/MS...

Human contact with mercury has been ongoing for centuries and was previously considered a legitimate means of treating different cutaneous and systemic conditions. Toxicity from this heavy metal may occur from exposure to elemental, inorganic, and organic forms of mercury. This article outlines the signs and symptoms of mercury poisoning and the different clinical conditions with assorted cutan...

Hair dye ingestion is frequently reported from Africa, the Middle-East, and the Indian subcontinent. The main component of hair dye causing toxicity is Paraphenylenediamine (PPD). This compound causes contact dermatitis in susceptible individuals,but when ingested it has been found to cause angioneurotic edema, rhabdomyolysis and renal failure. We report a case of paraphenylenediamine poisoning.

Polymeric hydrogels are used as wound dressing material since these materials show advantages such as pain relief, exudates absorption, barrier to microorganisms, permeability, and others. This article shows the results obtained in a study aiming to know the biological performance of different polymeric materials to be used in contact with skin: PVP hydrogels and acrylate adhesive. The biocompa...
