Relationship between styrene exposure and prolactin secretion in human and animal studies: A systematic review

Abstract

Styrene is widely used in industrial applications. Inhalation exposure occurs in the industry. Some studies indicated that serum prolactin concentrations increased after exposure to styrene, while other studies found no change. In this systematic review, the search was done with the keywords styrene and prolactin in the PubMed, Science Direct, Web of Science and Scopus databases, regardless of the publication period. 118 studies were obtained and only seven articles were finally selected according to exclusion and inclusion criteria. The effect of styrene on prolactin secretion was selected in both human and animal studies. The increased response was seen in inhalation exposures. Subcutaneous exposure has no significant effect on prolactin levels. The observed responses were both dose-dependent and gender-dependent. Changes in serum prolactin were more frequent in women compared to exposed men. Dopamine depletion was not observed in all studies, so more tests on laboratory animals are necessary to clarify the possible mechanism.

Assessment of cheese frauds, and relevant detection methods: A systematic review

“…Because each stage of the cheese production process has a function that affects the characteristics of the final product. Mainly the steps include ingredient selection and preparation; natural cheese should be chosen and ground (based on age, pH, taste, and intact casein content), choosing the suitable emulsifying salt, formulation, and calculation of additional components (to achieve the desired moisture, fat, salt, and pH values of the finished product by legal requirements), processing and storing processed cheese (heating and combining during cooking), packaging, chilling, and storing ( Kapoor and Metzger, 2008 , Çelik and Yuksel, 2016 , Sadighara et al, 2022 ).…”
