Short histological kaleidoscope - recent findings in histology. Part IV.

The paper provides an overview of the current understanding of different cells and structures' biology [e.g., blood-retinal barrier, Bruch membrane, Clara (club) cells, brush cells and tuft cells, Merkel cells, Hofbauer cells, cytokeratins], including their origin, structure, function, and role in disease pathogenesis, and of the latest findings in the medical literature concerning the paracortex of the lymph nodes.

The effects of radiofrequency electromagnetic radiation emitted by mobile phones on rat parotid gland histology - an experimental study.

Objective: The advancement of telecommunication technology and devices promptly transformed mobile phones into indispensable objects in our day-to-day lives, but their biological effects remain unclear. Therefore, this study aimed to investigate the potential histopathological changes induced by mobile phone radiation in the parotid gland and the nearby tissues.

Materials And Methods: Thirty female Rattus Norvegicus rats were divided into three groups: group 1 (exposed for 30 days), group 2 (exposed for 60 days), and control group (non-exposed).

antimicrobial activity of silver nanoparticles against selected Gram-negative and Gram-positive pathogens.

Background And Aim: Infections caused by pathogenic bacteria increase patient morbidity and mortality and significantly raise treatment costs. The use of silver nanoparticles as an alternative treatment for and indicates their antibacterial effect and prompts medical research to consider the next generation of antibacterial drugs that could change antibiotic therapy. By combining silver nanoparticles with different classes of antibiotics, the antibacterial effect is evidenced by increased values of the inhibition zone compared to the values obtained for some antibiotics commonly used in the treatment of bacterial infections.

In vitro photothermal therapy of pancreatic cancer mediated by immunoglobulin G-functionalized silver nanoparticles.

Pancreatic cancer is one of the most aggressive forms of cancer, and treatment options are limited. One therapeutic approach is to use nanoparticles to deliver the active agent directly to pancreatic cancer cells. Nanoparticles can be designed to specifically target cancer cells, minimizing damage to healthy tissues.
