Aortic cross-clamping induced ischemia reperfusion (IR) is an important factor in development of postoperative acute cardiac injury following abdominal aortic surgery. We investigated the possible antioxidant/anti-inflammatory effects of fluoxetine (FLX), which used widely as a preoperative anxiolytic, on cardiac injury induced by IR of infrarenal abdominal aorta. FLX was administered to IR (60-min ischemia and 120-min reperfusion) performed rats for 3 days, once daily at 20 mg/kg, i.p. dosage. Results were compared to control and non-FLX treated IR performed rats...

Piezoelectric composite (p-NC) made of a polymeric matrix and piezoelectric nanoparticles with conductive additives is an attractive material for many applications. As the matrix of p-NC is made of viscoelastic materials, both elastic and viscous characteristics of the matrix are expected to contribute to the piezoelectric response of p-NC. However, there is limited understanding of how viscoelasticity influences the piezoelectric performance of p-NC. Here we combined analytical and numerical analyses with experimental studies to investigate effects of viscoelasticity on piezoelectric performance of p-NC...

Cutaneous metastasis is considered as a hazardous condition depending on the mean survival around 9 months, which usually originates from cancers of the breast, lung, ovary, colon, and rarely from the cervix. The crucial prognostic factor of cutaneous metastasis depends on the period between the primary malignancy and cutaneous metastasis. We report two cases of the unusual presentation of squamous cell cancer of the cervix that developed vulvar and umbilical metastasis in the 5(th) month of primary treatment...

INTRODUCTION: Atherosclerosis might diminish the nutrient supply to intervertebral discs (IVD), leading to disc herniation. Therefore, there is interest in determining the possible association between the blood lipid profile and lumbar disc herniation (LDH). We aimed to evaluate the association between blood lipids and LDH in a homogeneous group of patients, controlling for age- and sex-specific effects. MATERIAL AND METHODS: This is a case-control study which consisted of 100 individuals (mean age: 41...

Transvenous pacemaker or implantable cardioverter defibrillator (ICD) implantation procedures are usually performed under local anesthetic, and prilocaine is the most common agent to be used. The data regarding methemoglobinemia after cardiac device implantation are scarce. Thus, presently described is the case of a 47-year-old female patient with arrhythmogenic right ventricular cardiomyopathy/dysplasia who underwent ICD implantation for secondary prophylaxis and developed cyanosis as a result of prilocaine-associated methemoglobinemia...

PURPOSE: To determine the effect of aging on corneal biomechanical parameters measured via ocular response analyzer in a homogenous healthy Caucasian population. METHODS: A total of 2039 Caucasian adults were consecutively recruited and divided into seven groups according to decades of age. The difference in mean corneal hysteresis (CH), mean corneal resistance factor (CRF), mean Goldmann-correlated intraocular pressure (IOPg), and mean corneal-compensated IOP (IOPcc) between decades of age were investigated...

Among nucleic acid based delivery platforms, self-amplifying RNA (saRNA) vectors are of increasing interest for applications such as transient expression of recombinant proteins and vaccination. saRNA is safe and, due to its capability to amplify intracellularly high protein levels, can by produced from even minute amounts of transfected templates. It is an obstacle to full exploitation of this platform, though, that saRNA induces a strong innate host immune response. In transfected cells pattern recognition receptors sense double-stranded RNA intermediates and via activation of protein kinase R (PKR) and interferon signaling initiate host defense measures including a translational shut-down...

Orbital floor fractures of varying sizes commonly occur after orbital injuries and remain a serious challenge. Serious complications of such fractures include enopthalmos, restriction of extraocular movement, and diplopia. There is a dearth of literature that can be applied widely, easily, and successfully in all such situations, and therefore there is no consensus on the treatment protocol of this pathology yet. Autogenous grafts and alloplastic and allogenic materials with a wide variety of advantages and disadvantages have been discussed...

BACKGROUND: Cystinosis is a rare metabolic genetic disorder caused by a mutation in the cystinosin lysosomal cystine transporter (CTNS) gene. The diagnosis of nephropathic cystinosis (NC) is made by observing corneal cystine crystals and/or measuring the cystine content of leukocytes. Analysis by the CTNS gene mutation confirms the diagnosis of cystinosis. But leukocyte cystine level measurement and CTNS gene analysis haven't been widely available and cystine crystals in the cornea may not be apparent in the first months of life...

BACKGROUND: In patients with melanoma, early dissemination via lymphatic and hematogenous routes is frequently seen. Thus, besides clinical follow-up examination and imaging, reliable melanoma-specific serological tumor markers are needed. PATIENTS AND METHODS: We retrospectively compared two serum markers for melanoma, S100 and melanoma-inhibitory activity (MIA), for monitoring of patients with metastatic melanoma under either adjuvant or therapeutic vaccination immunotherapy with dendritic cells (DC)...

BACKGROUND Whether or not there is a relationship between the newly-discovered irisin hormone and bone healing is not yet known. The aim of this study was to investigate what effect irisin hormone has on the bone healing process. MATERIAL AND METHODS The study included 21 adult patients with a diagnosed fracture of the lower extremity (femur or tibia). Informed consent was obtained from all the patients. A total of four venous blood samples were taken from the patients: before fracture stabilization, then postoperatively on days 1, 10, and 60...

Patients with de Winter syndrome, also termed anterior ST-segment elevation myocardial infarction (STEMI)-equivalent, represent 2% of all patients with acute anterior myocardial infarctions admitted to emergency departments (EDs). STEMI-equivalents do not present with classical electrocardiogram (ECG) changes but exhibit a critical stenosis of the left anterior descending (LAD) coronary artery. This is under-recognized by clinicians and is therefore associated with high morbidity and mortality. Here, we report a rare case of a novel, typical, STEMI-equivalent ECG pattern without obvious ST-segment elevation in a 34-year-old female who presented to our ED with substantial chest pain and a large, acute, transmural anterior myocardial infarction caused by acute occlusion of the LAD coronary artery...

INTRODUCTION: Canal wall down (CWD) tympanomastoidectomy is commonly used to treat advanced chronic otitis media or cholesteatoma. The advantages of CWD mastoidectomy are excellent exposure for disease eradication and postoperative control of residual disease; its disadvantages include the accumulation of debris requiring life-long otological maintenance and cleaning, continuous ear drainage, fungal cavity infections, and the occurrence of dizziness and vertigo by changing temperature or pressure...
