Chemical effects

Nowadays, there are many factors causing the decrease of male reproductive function such as diet, routine, chemical, ... But some of them have not been paid appropriate attention to, especially the use of paracetamol, which has a significant negative effect on the reproductive process. In this study, we will summarize the results of several studies on the harmful effects of prolonged high-dose use of paracetamol on sperm number, quality, portability and testicular morphology in experimental animals and humans.

This study investigated the in vitro effects of ZnO NP and chemical UV filters commonly used sunscreens on the function of immortalised and primary skin cells. ZnO particulates (30 nm, 80 nm and 200 nm) were compared to the chemical UV filters: butylmethoxydibenzoylmethane (BMDBM) ethylhexylmethoxycinnamate (EHMC), ethylhexylsalicylate (EHS), homomenthylsalicylate (HMS) and 4-methylbenzylidenecamphor (MBC). Human epidermal keratinocytes (NHEK), epidermal melanocytes (NHEM), dermal fibroblasts (NHDF) and the immortalised keratinocyte HaCaT cell line were used in this study.

It was demonstrated that Poly(p-Xylylene) (PPX) could be prepared from α,α’-Bis(Alkoxy or Aryloxy) –p-Xylenes via chemical vapor decomposition (CVD)- method. This is one-step process and there are side products by the CVD-process. This effect depends both on the CVD- condition and the properties of the starting monomer. The structure and thermal behavior of the material were characterized by FTIR, UVvis spectroscopy, elemental analysis, wide-angle X-ray diffraction, DTA and DSC.
