Objective: In 2014, enrolled 20 patients who applied to the Unit of Assisted Reproduction Techniques, Konya Necmettin Erbakan University. Based on the presence of hyaluronic acid (HA) in the oocyte-cumulus cell complex, sperm attached to HA in vivo were modeled in vitro. Available healthy sperm obtained in the swim-up procedure using HA were investigated.
Materials And Methods: This observational cohort study, a routine analysis was conducted on the ejaculation samples obtained from 20 patients. We divided each sample into two groups and the swim-up method was applied. Human serum albumin (HSA, 0.5%) was added to samples from the first group. HA (10%) was added to samples from the second group. We determined the floating linear and non-linear sperm concentrations of both groups annexin V was used to determine the rate of apoptosis of these sperm.
Results: Following swim-up, linear and non-linear sperm concentrations were higher in the group that contained HA compared to the group with HSA. However, there was a significantly higher apoptosis rate in the HSA group compared to the HA group.
Conclusion: The addition of HA to the medium in the swim-up procedure positively affected sperm parameters. Thus, healthier sperm cells were obtained without DNA damage and with high motility.

Extracellular vesicles (EVs) emerged as critical contributors to the pathogenesis of vascular endothelial barrier dysfunction during the inflammatory response to infection. However, the contribution of circulating EVs to modifying endothelial function during dengue virus infection remains unclear. In this study, we showed that severe dengue patients' plasma-derived EV (SD-EV) were found to carry elevated levels of different protein cargos, e.

Intricate crosstalk among various lung cell types is crucial for orchestrating diverse physiological processes. Traditional two-dimensional and recent three-dimensional (3D) assay platforms fail to precisely replicate these complex communications. Many lung models do not effectively reflect the multicellular complexity of lung tissue.

Background: Myoepithelial carcinoma is a very rare yet aggressive tumor in children. Surgical intervention and local radiotherapy often lead to post-therapy complications, affecting both the aesthetic and functional quality of life in survivors. Hyaluronic acid (HA) dermal fillers offer a minimally invasive option to improve the appearance and quality of life for these patients once they are declared tumor-free.

Amniotic epithelial stem cells (AEC) hold potential for tissue regeneration, especially through their conditioned medium (AEC-CM) due to their immunomodulatory and regenerative effects. Nevertheless, advanced drug delivery systems such as hydrogels are needed to enable clinical applications. Herein, an gellable hyaluronic acid and polyethylene glycol-based iEDDA-cross-linked hydrogel was developed for the encapsulation and controlled release of AEC-CM.
