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.

The Effects of Adipose-Derived Mesenchymal Stem Cells and Adipose-Derived Mesenchymal Stem Cell-Originating Exosomes on Nerve Allograft Regeneration: An Experimental Study in Rats.

Introduction: Nerve regeneration has been the subject of many studies because of its complex mechanism and functional outcome. Mesenchymal stem cells and exosomes are promising factors in regeneration in many areas. Reconstruction of nerve defects is a controversial issue, and nerve allografts are promising alternatives with many advantages.

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.

Effects of Adipose-Derived Stem Cells and Platelet-Rich Plasma for Prevention of Alopecia and Other Skin Complications of Radiotherapy.

Background: Radiotherapy (RT) involves the use of ionizing radiation in treating malignancies and benign disorders. However, RT damages target and healthy surrounding tissues in a dose-dependent manner. This effectively reduces patient compliance and quality of life, thereby warranting the prevention of RT-induced adverse effects on skin.

Efficacy of Hyaluronic Acid in The Selection of Human Spermatozoa with Intact DNA by The Swim-up Method.

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.

Treatment of Acute Vocal Fold Injury With Platelet-Rich Plasma.

Objectives: 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. The aim of the present study was to evaluate effectiveness of PRP application on scar tissue of acute vocal fold injury.

Intra-articular platelet-rich plasma injection for the treatment of temporomandibular disorders and a comparison with arthrocentesis.

Background: Temporomandibular joint (TMJ) internal derangements are progressive painful conditions and cause joint dysfunction, joint sound, malocclusion, and locking of the mouth. Conservative and invasive techniques can be used for the treatment of TMJ internal derangements. The objective of the present study was to examine the benefit of an intra-articular platelet-rich plasma (PRP) injection and to compare this with arthrocentesis.

Improvement in embryo quality and pregnancy rates by using autologous cumulus body during icsi cycles.

Objective: To determine whether the addition of intact cumulus cell mass (ICM) to both embryo culture (EC) and embryo transfer (ET) improves embryo quality and pregnancy rates.

Material And Methods: A total of 133 infertile couples were included, of which 67 received ICM (study group) and 66 did not (control group). The ICM was obtained from a simple cutting of the cumulus corona oocyte complex (CCOC).

Influence of cumulus cell coculture and cumulusaided embryo transfer on embryonic development and pregnancy rates.

Objective: In this study, we aimed to evaluate the influence of autologous cumulus oocyte complex (COC) coculture on embryonic development and quality, and investigate the implantation and pregnancy rates after cumulus-aided embryo transfer in the ICSI-ET cycles.

Material And Methods: Ninety five consecutive infertile women undergoing their first cycle of IVF teratment were included in the study. The cases were divided into two groups.

Autologous transplantation of arterial cells improves cardiac function in a rabbit model of infarcted myocardium.

Cellular cardiomyoplasty is a promising approach for the treatment of severe heart failure. However, the question which cell line is the best to use is still a matter of debate. In this study, we aimed to evaluate the efficacy of arterial media-intima cell suspension (AMICS) transplantation in rabbit myocardial infarct model.

Improvement in rabbit corneal cell suspension viability after freezing with Gingko Biloba extract.

We investigated whether the addition of Gingko Biloba extract (EGb 761) to rabbit corneal epithelial medium before cell freezing improved cell viability after freezing then thawing. After removal of corneas, they were treated with enzymes and the corneal epithelium was prepared as a single cell suspension in freezing media with or without EGb 761. After freezing for two weeks then thawing, a higher cell viability was found in the cornea cell suspensions which had been frozen pretreated with EGb 761 in the media.

Improvement In Rabbit Corneal Cell Suspension Viability After Freezing With Gingko Biloba Extrakt.

We investigated whether the addition of Gingko Biloba extract (EGb 761) to rabbit corneal epithelial medium before cell freezing improved cell viability after freezing then thawing. After removal of corneas, they were treated with enzymes and the corneal epithelium was prepared as a single cell suspension in freezing media with or without EGb 761.
