Investigating the interaction of zno nanoparticles with flagellum and fimbriae in multi-drug resistant uropathogenic bacteria encoding fli and fim genes.

Due to the increasing occurrence of drug resistant urinary tract infections (UTI) among children, there is a need to investigate alternative effective treatment protocols such as nanoparticles. Flagella and fimbriae are primary factors contributing the virulence of urinary tract infecting bacteria. The aim of this study was to assess the antibacterial effects of zinc oxide nanoparticles which have been synthesized using both chemical and green methods on multi-drug resistant (MDR) uropathogenic bacteria encoding fli and fim genes and investigating their binding ability to bacterial appendage proteins.

Assessment of Antimicrobial Activity of Chitosan, ZnO, and Urtica dioica-ZnO NPs Against Staphylococcus aureus Isolated from Diabetic Ulcers.

Staphylococcus aureus (S. aureus) is considered as one of the challenging ulcer infections in diabetic patients especially those who have acquired antibiotic-resistant infections. Nanotechnology products have enormous potential to treat diseases including infectious diseases.

[Management of subjective tinnitus].

MANAGEMENT OF SUBJECTIVE TINNITUS. Subjective tinnitus, which is the perception of a sound in the absence of any actual external or internal acoustic stimulation, is a common symptom affecting about 15% of the population. It should be distinguished from objective tinnitus, which is the perception of a sound produced inside the human body (vascular pulsation or muscular contraction).

Harmful impact of treatment refusal in T3-4M0 endolaryngeal squamous cell carcinoma candidates for total laryngectomy: A STROBE analysis.

Purpose: To evaluate the consequences of treatment refusal in total laryngectomy (TL) candidates with T3-4M0 endolaryngeal squamous cell carcinoma (SCC).

Materials And Methods: A retrospective observational study was conducted in an inception cohort of 576 isolated T3-4M0 endolaryngeal SCC candidates for TL consecutively managed between 1970 and 2019 in a French university teaching hospital. The main endpoint was survival time and cause of death in 2 groups.

Iron oxide nanoparticles coated with polydopamine as a potential nano-photothermal agent for treatment of melanoma cancer: an in vivo study.

Melanoma is a metastatic cancer resistant to a wide range of therapies, including standard chemotherapy and radiation therapy, and cannot be treated with existing treatments owing to its intrinsic drug resistance. In terms of convenience and cheap cost of fabrication, one of the novel treatments is using polydopamine-coated iron oxide nanoparticles (IONs@PDA). Iron oxide nanoparticles (IONs) were synthesized (7.
