Purpose: To evaluate the serum levels of oxidative stress-related molecules in patients with ocular hypertension (OHT) and primary open-angle glaucoma (POAG) compared with healthy controls.
Methods: Treatment-naive patients with no known systemic diseases and with OHTand POAG diagnosis were recruited for the study. Also, age- and gender-matched healthy volunteers with no ocular and systemic diseases were included as controls.
The purpose of this study is to investigate the clinical and histopathological effectiveness of topical amniotic membrane extract (AME) applied at a clinically relevant dose in an experimental corneal alkaline burn model and to compare the results with amniotic membrane transplantation (AMT) as one of the most frequently used biologically based treatment options. To create an alkaline burn model, NaOH-impregnated filter paper was applied to all rabbits for 30 s. Rabbits were divided into 3 groups: Group 1 (n = 6): AME eye drop; Group 2 (n = 6): AMT; Group 3 (n = 4): control group.

Purpose: This study investigates the superiority of sterile lyophilized amniotic membrane extract (AME) prepared at a clinically correlated dose over amniotic membrane transplantation (AMT) in an experimental corneal wound model.
Methods: AME was prepared from a pool of five amniotic membranes. After homogenizing the membranes, they were lyophilized and sterilized by gamma radiation to obtain sterile, lyophilized AME powder.
Purpose: To examine posterior ocular structures with optical coherence tomography (OCT) in individuals using a phosphodiesterase 5 inhibitor (PDI, tadalafil).
Method: This prospective study included 26 eyes of 26 patients who used 1 tablet of 5-mg tadalafil regularly every day for 1 month due to erectile dysfunction. The routine ophthalmological examinations of the participants were performed at the pre-tadalafil and post-tadalafil first-month visits.
Purpose: The objective of this study is to compare the efficacies of 3 different intrathecal doses (80, 120, and 160 mcg) of morphine in achieving postcesarean delivery analgesia and the severity of the side effects thereof.
Design: A prospective, randomized, double-blind study.
Methods: A total of 150 pregnant women between the ages of 18 and 40, with a gestational week >36, who were planned to have elective cesarean section were included in the study.
Objective: The aim of this study is to show the surgical trend over the past 14 years using the data from five major centers in Turkey with accumulated experience in benign prostatic hyperplasia (BPH) surgery.
Material And Methods: This study included 94,954 patients with low urinary tract symptoms (LUTSs) secondary to BPH. By using electronic databases, we identified 7,163 patients who underwent BPH surgery, including monopolar transurethral prostate resection (M-TURP), bipolar transurethral prostate resection (BTURP), transurethral incision of the prostate (TUIP), open prostatectomy (OP), and holmium laser enucleation of the prostate (HoLEP) from 2006 to 2019.
Aims: We aimed to investigate fertilisation rates, quality of embryo, pregnancy and live birth rates, endocrine, sexual function, psychological status and quality of life of cases diagnosed with Klinefelter syndrome (KS).
Methods: Clinical findings, hormone values and semen analyses in patients with nonmosaic KS (Group 1, n = 121) and those with non-genetic nonobstructive azoospermia (NOA) (Group 2, n = 178) were retrospectively analysed. Sperm retrieval outcomes with microdissection testicular sperm extraction (micro-TESE), fertilisation rates and embryo quality, pregnancy, abortion and live birth rates were compared.
Aims: Erectile dysfunction (ED) is a common condition affected by many factors. We aimed to show the impact of the metabolic syndrome (MeTS) on male sexual function based on visceral adiposity index (VAI).
Methods: Participants who met MeTS criteria (Group 1, n = 96) and did not meet MeTS criteria (Group 2, n = 189) were included in this cross-sectional study.
Errors of folate/homocysteine pathways which are critical for transferring methyl groups have been suggested to affect male fertility. We aimed to evaluate the methylation patterns of the promoter of methylenetetrahydrofolate reductase (MTHFR) gene in infertile males and to investigate the association between MTHFR promoter methylation and success of sperm retrieval. Thirty-five nonobstructive azoospermic and 46 severe oligozoospermic patients constituted the study group and were compared with 49 fertile and/or normozoospermic men.

Aim: To show a possible relationship between ED and VAI levels representing adipose tissue dysfunction and to identify a cutoff value of the VAI for ED.
Methods: This prospective cross-sectional study included 276 participants in 5 groups: non-ED, mild ED, mild-moderate ED, moderate ED, and severe ED.
Objective: To compare the patient's satisfaction and long-term results of 2 penile plication procedures in patients with penile curvature.
Methods: This retrospective study included 387 patients with congenital penile curvature (n = 260) and Peyronie's disease (n = 127) who underwent surgical correction of penile curvature with penile plication procedures. Of the patients, 202 underwent plication of tunica albuginea with the Lue's 16-dot technique, while 185 underwent highly superficial excision of tunica albuginea with the modified Nesbit corporoplasty.
Impacts of a subinguinal microsurgical varicocelectomy on the sperm parameters and fertility rates were investigated in three different ages according to their age at the time of the varicocelectomy: Group 1 was ≤20 years old, Group 2 was 21-30 years old, and Group 3 was ≥31 years old. The patients were also classified both preoperatively and post-operatively according to the total motile sperm count (TMSC) into the following categories: invitro fertilisation, intrauterine insemination and naturally fertile. The proportion of patients who upgraded to a higher TMSC category level was calculated, and natural fertility rates were recorded.

Aims: The primary objective of this experimental, randomized, controlled trial was to test the hypothesis asserting that intrathecal dexketoprofen trometamol would demonstrate an analgesic effect during postoperative period.
Objective: This study aimed to compare the effects of topical and systemic lignocaine on the circulatory response to direct laryngoscopy performed under general anaesthesia.
Methods: Ninety-nine patients over 20 years of age, with a physical status of I-II (classified according to the American Society of Anesthesiologists), were randomly allocated to 3 groups. One group received 5 ml of 0.
Purpose: To compare effects of music, white noise, and ambient (background) noise on patient anxiety and sedation.
Design: Open, parallel, and randomized controlled trial.
Methods: Seventy-five patients aged 18 to 60 years who were scheduled for surgical procedures under spinal anesthesia were randomly assigned to ambient noise (Group O), white noise (Group B), or music groups (Group M).
Background And Objectives: Leigh syndrome (LS) is a rare disease caused by abnormalities of mitochondrial energy generation. The central nervous system is most frequently affected, with psychomotor underdevelopment, seizures, nystagmus, ophthalmoparesis, optic atrophy, ataxia, dystonia, or respiratory failure. Surgical and anesthetic procedures stimulate the tracheal irritability, and could exacerbate risks of aspiration, wheezing, breathing difficulties, gasping, hypoventilation, and apnea.

Free radicals, oxidative stress, and antioxidants have become commonly used terms in modern discussion of disease mechanisms. Accumulation of evidence suggests that toxic oxygen-derived reactive free radicals (superoxide, peroxide and hydroxyl radicals) play a crucial role in etiology of diabetes and its complication. Thus, it was aimed to determine the role of thyroid hormones in reversal of antioxidatant enzyme activities and lipid peroxidation alterations observed in experimentally induced diabetic rat hearts.
