Although women may undergo changes in sexual function during pregnancy, there are limited studies correlating possible sexual function changes to androgen blood levels during the pregnancy.To search for a possible correlation, we performed a cross-sectional observational study to assess sexual function scores and androgen blood levels of women during pregnancy.A total of 589 healthy pregnant women were recruited to the present cross-sectional study. Of these patients, 116 (19.6%), 220 (37.3%), and ...

Heterojunction solar cells composed of hydrogenated amorphous silicon (a-Si:H) and c-Si has been widely studied due to its excellent photovoltaic characteristics. In this study, we studied the structural and optical properties of a-Si:H thin films for heterojunction solar cells by using SEM, TEM and ellipsometry. We found that uniform deposition of a-Si:H thin film on substrate is crucial to reach high solar cell efficiencies.

We consider a competitive facility location problem in which two firms engage in a leader–follower game. Both firms would like to maximize the customer demand that they capture. Given the other player’s decision, each player’s problem is the classical maximal covering location problem. That is, the leader has to solve a bi-level problem in which the second-level problem is NP-hard. To overcome this, we use the greedy add algorithm as an approximation for the follower’s response and formulate a mixed- ...

Objective: We sought to reveal whether the severity of angina pectoris affects sleep quality after elective coronary artery bypass grafting. Material and methods: Patients scheduled to undergo isolated coronary artery bypass grafting were divided into two groups, having a recent myocardial infarction (Group 1, n=22, mean age 59.40±7.79 years) or not having a recent myocardial infarction (Group 2, n=30, mean age 59.73±7.72 years). The assessment included the Canadian Cardiovascular Society Angina Score, ...

There are limited data showing right ventricular preload increase due to high-flow arteriovenous fistulas (AVFs). This cross-sectional study investigated whether high AVF flow had an impact on right ventricular function in patients undergoing hemodialysis. Sixty-four patients aged between 18 and 85 years who were on routine hemodialysis with >2 hemodialysis sessions per week for at least 3 months via an AVF were studied. Patients with inadequate flow fistulas, severe chronic obstructive pulmonary ...

Background: In this retrospective study, we evaluated our surgical outcomes of transscleral intraocular lens (IOL) fixation and introduced a simple, quick, and effective method to fixate and bury the sutures in the sclera to avoid suture exposure. Methods: Eyes were divided into 3 groups according to surgical technique. Half-thickness scleral flaps were prepared, and polypropylene suture ends were cut short in group 1 (12 eyes). Suture ends were left long without flaps in group 2 (47 eyes) and were ...

In 1973, a 10-year-old boy with rheumatic mitral stenosis underwent mitral valve replacement with use of a Starr-Edwards caged-ball valve (SECBV) model 6120. In March 2013, the adult patient presented with severe aortic stenosis and underwent mechanical aortic valve replacement. In June 2014, at age 51 years, he was admitted to our hospital with atrial fibrillation. A transthoracic echocardiogram showed an aortic valve prosthesis with mild regurgitation, left atrial enlargement to dimensions of 4. ...

Osteochondral lesions of the talus present with symptoms of pain and painful motion, affecting the quality of the patient’s daily life. We evaluated the 2-year short-term outcomes of patients whose large osteochondral lesions of the talus were treated with medial malleolar osteotomy and a mosaic graft harvested from the knee on the same side. A total of 32 patients who had cartilage lesions due to osteochondritis dissecans in the medial aspect of the talus underwent mosaicplasty after medial malleolar ...

This paper presents the design and construction of a viable pupillometer system and demonstrates its merits with extensive validation tests.A web camera was modified by removing its infrared filter and mounted on a chin rest. Light emitting diodes (LEDs) operating at infrared and visible spectra were integrated to provide background and light stimulus, respectively. The LEDs were controlled by a microprocessor board. Stimulation was presented using a periodic paradigm with variable period and duty ...

Attention deficit hyperactivity disorder (ADHD) is the most common behavioral disorder of childhood and it has 5% prevalence among children worldwide [1]. In the treatment of ADHD stimulant medications are recommended as the first choice of pharmacotherapy [2]. Methylphenidate-HCl is a sympathomimetic amine derivative pharmacological agent; and it is widely used in the treatment of ADHD. Although there are some articles showing that oral methylphenidate increases the risk of glaucoma [3], to the best ...

The purpose of the present study is to investigate the protective effect of melatonin against early period parotid gland damage, caused by low- and high-dose rate beams in different dose plans, by using experimental rat models. Eighty Sprague Dawley rats were divided into ten randomized groups, each group being different in terms of dose plan and dose rate. Subjects in the control group were given only sodium chloride. Subjects in the melatonin-only group received 10 mg/kg melatonin. The head and ...
