Báez, Jessica Martínez, Mauricio Báez, Edwar FuentesAbstractSome minor constituents of honey samples were determined through a fluorometric-chemical characterization method and related multifactorially with their antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa and with their geographical origin. Rotated principal component analysis identified five significant components in honey: three related to antibacterial activity a...

To solve above issues, a bioactive coating consisted of gelatin (Gel) and chitosan-graft-polyaniline (Chi-PANI) was fabricated with layer-by-layer (LBL) assembly technique on titanium dioxide nanotubes (TNT) substrates. Scanning electron microscopy (SEM), water contact angle (WCA) measurement X-ray photoelectron spectroscopy (XPS) and at...

ConclusionsClHO at medium-low concentrations (300 or 500 mg/L) is a good antiseptic that can be used on wounds and mucous membranes for 5-10 minutes. Lower concentrations of ClHO, as well as of the other antiseptics studied, were less effective or more altered by the biofilm. ClHO at a concentration of 1500 mg/L is very effective in presence or absence of biofilm that can be used on healthy skin for 5 minutes.

Publication date: Available online 23 January 2020Source: Nanomedicine: Nanotechnology, Biology and MedicineAuthor(s): Bing Yu, Zhongxia Wang, Layla Almutairi, Songping Huang, Min-Ho KimAbstractIron oxide nanoparticles (IONPs) have been increasingly used in various biomedical applications in preclinical and clinical settings. Although the interactions of IONPs with macrophages have been well-reported in the context of nanoparticle toxicity, harnessing the capacity of IONPs in reprograming macrophages towards bactericidal activity has not been explored. Here, using an in vitro culture model of macrophages and an in vivo mou...

Herein, three-dimensional (3D) mesoporous bioactive glass (MBG) nanofibrous scaffolds doped with copper (Cu) were synthesized via a one-pot template-assisted sol-gel method followed by calcination. The morphology, structure, pore structure, in vitro bioactivity, cell biocompatibility, and an...

The relationship between the timing of antibiotics and mortality among septic shock patients has not been examined among patients specifically with Staphylococcus aureus bacteremia. The results of this study further support the importance of prompt appropriate antibiotic administration for patients with septic shock. Physicians should consider acting quickly to administer antibiotics with S. aureus coverage to any patient suspected of having septic shock.

"Clinical Aspects of Chronic Granulomatous Disease in Upper Egypt". Immunol Invest. 2020 Jan 22;:1-13 Authors: El-Mokhtar MA, Salama EH, Fahmy EM, Mohamed ME Abstract Chronic granulomatous disease (CGD) is a rare inherited primary immunodeficiency disorder that affects phagocytes and is characterized by a marked increased susceptibility to severe bacterial and fungal infections. We aimed to describe the clinical presentations of pediatric patients with CGD in Upper Egypt and to identify the defective component of NADPH oxidase. Pediatric patients diagnosed with CGD within one year from Januar...
