Investigation of the Effect of Hafnium Chloride on Sperm Viability and Motility in Normospermic Cases: An In Vitro Study.

Introduction: Hafnium alloys are employed in medical applications due to their biocompatibility and high corrosion resistance. These alloys have demonstrated osteogenic and antimicrobial activities in surgical implants and have been utilized in the treatment of sarcoma. Additionally, a sensor based on hafnium nanoparticles has been reported for the detection of coronavirus disease 2019.

Brain-Derived Neurotrophic Factor Levels in Mesenchymal Stem Cell Culture Fluid Under Different Culture Conditions.

Objective: Mesenchymal stem cells are used in various fields, such as cellular therapy, regeneration, or tissue engineering. It has been shown that they exhibit many protective factors and also work as a modulating chief within the region in which they are administered. There are studies on both the therapeutic and neuroprotective effects of brain-derived neurotrophic factor.

Histopathological Evaluation of Platelet-Rich Plasma Effect in Acute Tympanic Membrane Perforation.

Unlabelled: Platelet-rich plasma (PRP) is a reliable and has low side-effect profile and has beneficial effects on wound healing. Its investigatory effects on wound-healing process were shown on various tissues. This study aims to investigate PRP's local application effects to perforated rat TM in terms of healing and histopatological outcomes.

The Role of Stem Cells Derived From the Mesenchyme of the Umbilical Cord in Reducing Immunosuppressive Drug Doses Used in Allogenic Transplantations.

Background: This study evaluated the potential of Wharton's jelly mesenchymal stem cells with high tolerogenic properties in reducing immunosuppressive dosage and related adverse effects.

Methods: A 4- to 6-week-old, 30-40 g weight, male inbred CD57BL/6 mice were used as skin allograft donors, whereas Balb/c mice with similar characteristics were used as recipients. Wharton's jelly stem cells were obtained from a commercial kit sourced from human umbilical cord.

Validity and Reliability of the Turkish Version of the Pediatric Assessment Scale for Severe Feeding Problems.

Objective: The purpose of this study was to translate the Pediatric assessment scale for severe feeding Problems (PASSFP) into Turkish and investigate its validity and reliability.

Methods: The study included Turkish translation of the PASSFP, and investigating its reliability and criterion validity in relation with Children's eating behavior questionnaire (CEBQ).

Results: Cronbach Alpha reliability of T-PASSFP was 0.
