Endoplasmic Reticulum Stress in Myometrial Smooth Muscle Cells and Spontaneous Contraction Changes in the Uterus of Dehydroepiandrosterone-induced Polycystic Ovary Syndrome Rats.

Myometrial changes in polycystic ovary syndrome (PCOS) are poorly investigated. Thus, we aimed to investigate endoplasmic reticulum (ER) stress in myometrial smooth muscle cells and changes in spontaneous uterine contraction in PCOS. Twenty-one female Sprague-Dawley rats (21 days old) were divided into control (n = 7), vehicle (n = 7) and PCOS (n = 7) groups.

The effects of topical mafenide acetate application on skin graft survival in bacterial contaminated wounds.

Background: Infection related skin graft loss still remains as a common problem even with the use of systemic antibiotics. Mafenide acetate (Sulfamylon) is a topical antimicrobial agent with a wide spectrum of antimicrobial activity. Since mafenide acetate has the ability to penetrate the burn eschar, it was preferred in the treatment of infected full-thickness skin grafts.

Protective effect of paricalcitol in rat testicular damage induced by subchronic 1800 MHz radiofrequency radiation.

In the present study, the possible protective effects of paricalcitol (P) were investigated in testicular damage because of 1800 MHz radiofrequency radiation (RFR) exposure. Male Sprague Dawley rats 8-10 weeks old (n = 28) were randomly divided into four groups as control (C) (n = 7), RFR (n = 7, 1800 MHz RFR 1 h/day for 30 days), P (n = 7, 0.2 μg/kg paricalcitol, 3 times a week for 30 days), and RFR + P (n = 7, 1800 MHz RFR 1 h/day for 30 days +0.

Perifosine and vitamin D combination induces apoptotic and non-apoptotic cell death in endometrial cancer cells.

Endometrial cancer is the most common cancer of the female reproductive system. Combination treatment with specific agents has been widely used as a targeted therapy for cancer. In this study, we aimed to investigate the anti-proliferative and apoptotic effects of varying concentrations of perifosine and vitamin D on the human endometrial cancer cell line (HEC-1A).

Evaluation of the Rho A/Rho-kinase pathway in the uterus of the rat model of polycystic ovary syndrome.

The aim of this study was to investigate the expression of RhoA/Rho-kinase in the uterus and the effect of Rho-kinase inhibitors on uterine contractions of dehydroepiandrosterone (DHEA) induced polycystic ovary syndrome (PCOS) rats. Forty-four female Sprague-Dawley (21 days old) rats divided into three groups: The control group (n = 14, any procedure was not performed), vehicle group (n = 14, 0.2 ml of sesame oil, subcutaneous injection, 20 days) and PCOS group (n = 16, DHEA 6 mg/100 g in 0.

Effect of low-level 1800 MHz radiofrequency radiation on the rat sciatic nerve and the protective role of paricalcitol.

The nervous system is an important target of radiofrequency (RF) radiation exposure since it is the excitable component that is potentially able to interact with electromagnetic fields. The present study was designed to investigate the effects of 1,800 MHz RF radiation and the protective role of paricalcitol on the rat sciatic nerve. Rats were divided into four groups as control, paricalcitol, RF, and RF + paricalcitol.

GDF9 and BMP15 Expressions and Fine Structure Changes During Folliculogenesis in Polycystic Ovary Syndrome.

Background: Polycystic ovary syndrome is the most frequently seen endocrine disorder in women of reproductive age with a prevalence of about 10%.

Aims: To investigate the efficiency of growth differentiation factor 9 and bone morphogenetic protein 15 during folliculogenesis in a dehydroepiandrosterone-induced mouse Polycystic ovary syndrome model.

Study Design: Animal experimentation.

Effects of ozone therapy on facial nerve regeneration.

Introduction: Ozone may promote moderate oxidative stress, which increases antioxidant endogenous systems. There are a number of antioxidants that have been investigated therapeutically for improving peripheral nerve regeneration. However, no previous studies have reported the effect of ozone therapy on facial nerve regeneration.

Electrophysiological, biochemical and ultrastructural effects of radiotherapy on normal rat sciatic nerve.

Unlabelled: Abstract Purpose: The aim of the present study was to evaluate the electrophysiological, biochemical and ultrastructural changes on the rat sciatic nerve after radiotherapy.

Material And Methods: Thirty male Wistar albino rats were divided into three groups as: Control group (n = 10), Group I: 3 months after radiotherapy (n = 10), and Group II: 6 months after radiotherapy (n = 10). Groups I and II were irradiated with a (60)Co gamma source.

Effectiveness of the biophysical barriers on the peridural fibrosis of a postlaminectomy rat model: an experimental research.

Purpose: Long term results after surgical treatment of disc herniation have shown that epidural and/or peridural fibrosis formed during the healing process after surgical intervention. We conducted this experimental study to evaluation of the effectiveness of the bioresorbable barriers (ADCON-L and Seprafilm(®) Adhesion Barrier) on formation of the peridural fibrosis in rat model performed laminectomy.

Methods: Thirty-two male Wistar albino rats 250-350g body weight were distributed into three groups (CONTROL, AL group received ADCON-L; SAB group received Seprafilm(®) Adhesion Barrier).

Comparison of bony healing and cartilage degeneration following strut grafting and trapdoor procedures in an ovine model.

This experimental study compared bony healing and cartilage degeneration following strut grafting and trapdoor procedures for osteonecrosis of the femoral head in an ovine model. Osteonecrosis and a bony defect were created surgically in 16 hips of 8 Merino sheep, and the index grafting procedures were performed in a second session. Three months after surgery, the hips treated by strut grafting yielded better articular cartilage protection and bony healing compared to the osteonecrosis groups.

Protective effect of trapidil on long-term histologic damage in a rat model of testicular ischemia-reperfusion injury.

Objectives: Trapidil is an antianginal compound with a broad spectrum of pharmacological activities. In recent years, it has been used successfully to decrease ischemia-reperfusion injury in several organ systems. We evaluated the effect of trapidil on the long-term histologic damage in testicular ischemia-reperfusion injury.

The effect of tamoxifen on bladder functions and histology, and the role of estrogen receptor beta in a rat chemical cystitis model.

Aims: The purpose of this study was to investigate the effect of tamoxifen citrate on bladder functions and histology, and also to investigate the role of estrogen receptor beta (ER beta) in a rat chemical cystitis model.

Methods: The study included 37 female Sprague-Dawley rats. Chemical cystitis was induced by intravesical instillation of hydrochloric acid in 32 rats, and the treatment group (n = 15) received daily 0.

[The nitrosative effect of peripheral ischemia-reperfusion on lung and preventive of caffeic acid phenethyl ester].

Ischemia-reperfusion (IR) is characterized by microvascular disfunction and this involves both direct effected organ and remote organ by systemic inflammatory response. These remote effects of IR are most frequently observed in the lung and cardiovascular system. In this study we aim to determine lung damage which induced IR, and endothelial and microvascular disfunction using nitrosative markers.

Inhibition of poly(adenosine diphosphate-ribose) polymerase decreases long-term histologic damage in testicular ischemia-reperfusion injury.

PARP inhibitors have been used successfully to decrease ischemia-reperfusion injury in several organ systems.

Methods: Adult male Wistar rats were divided into four groups of 7 rats each.
