Shampoo treatment and hair conditioning have a direct impact on our wellbeing via properties like combability and haptic perception of hair. Therefore, systematic investigations leading to quality improvement of hair care products are of major interest. The aim of our work is a better understanding of complex testing and the correlation with quantitative parameters. The motivation for the development of physical testing methods for hair feel relates to the fact that an ingredient supplier like BASF can only find new, so far not yet toxicologically approved chemistries for hair cosmetics, if an in-vitro method exists.In this work, the effects of different shampoo treatments with conditioning polymers are investigated. The employed physical test method, dry friction measurements and AFM observe friction phenomena on a macroscopic as well as on a nanoscale directly on hair. They are an approach to complement sensoric evaluation with an objective in-vitro method.

Background: Lovastatin, the main lipid-lowering component in red yeast rice, is a golden anti-lipid drug, but its long-term application is continuously challenged by potential skeletal muscle atrophy. Daidzein, an isoflavone derived from soybeans and many Chinese medicines, shows therapeutic potential in treating muscle-related diseases and metabolic disorders. However, whether daidzein can improve lovastatin-induced muscle atrophy and the specific mechanism needs to further study.

Background: Gasdermin D (GSDMD) is a key effector molecule that activates pyroptosis through its N terminal domain (GSDMD-NT). However, the roles of GSDMD in colorectal cancer (CRC) have not been fully explored. The role of the full-length GSDMD (GSDMD-FL) is also not clear.

Infertility is a prevalent problem among 10% of people within their reproductive years. Sometimes, even advanced treatment options like assisted reproduction technology have the potential to result in failed implantation. Because of the expected changes in gene expression during both in vitro and in vivo fertilization processes, these methods of assisting fertility have also been associated with undesirable pregnancy outcomes related to infertility.

Objective: This study aims to investigate the molecular mechanisms by which YWHAG (Tyrosine 3-Monooxygenase/Tryptophan 5-Monooxygenase Activation Protein Gamma) promotes metastasis in bladder cancer. Specifically, it seeks to elucidate the role of YWHAG in driving cancer cell invasion and its potential as a prognostic marker for bladder cancer progression.
Methods: The expression pattern of YWHAG in both primary and metastatic bladder cancer tissues was analyzed using immunohistochemistry (IHC) to determine its correlation with clinical stage and prognosis in bladder cancer patients.
