In this study,four different Mg-Zn-Ca-Mn alloys were produced using gravity die casting *** content was kept constant in all alloys,while Zn and Ca were added in two different *** heat treatment was applied to all cast alloys and a specimen from each homogenized alloy was hot ***,mechanical properties,and corrosion behavior of the homogenized and hot rolled alloys were investigated as *** results were obtained;grain size decreased significantly with increasing Zn content,Zn promoted Ca 2 Mg 6 Zn 3 phase formation,corrosion resistance increased with increasing Zn/Ca atomic ratio,hot rolling resulted in much higher tensile strength but much lower ductility and *** the homogenized and hot rolled alloys,ZXM300-h alloy(hot rolled ZXM300 alloy)with its 146±2.5 MPa yield strength,229±3.7 MPa tensile strength,%1.6±0.1 elongation and 0.029 mm/*** corrosion rate exhibited the best mechanical properties and corrosion resistance to be used as a biodegradable alloy such as fracture bone plate material.

Tests for malingering in ophthalmology

引用

International Journal of Ophthalmology(English edition) 2013年第5期6卷 708-717页

作者： Ali Ihsan incesu Ministry of Health Konya State Hospital of Instruction Eye Clinic

· Simulation can be defined as malingering, or sometimes functional visual loss (FVL). It manifests as either simulating an ophthalmic disease (positive simulation), or denial of ophthalmic disease (negative simulation). Conscious behavior and compensation or indemnity claims are prominent features of simulation. Since some authors suggest that this is a manifestation of underlying psychopathology, even conversion is included in this context. In today’s world, every ophthalmologist can face with simulation of ophthalmic disease or disorder. In case of simulation suspect, the physician’s responsibility is to prove the simulation considering the disease/disorder first, and simulation as an exclusion. In simulation examinations, the physician should be firm and smart to select appropriate test (s) to convince not only the subject, but also the judge in case of indemnity or compensation trials. Almost all ophthalmic sensory and motor functions including visual acuity, visual field, color vision and night vision can be the subject of simulation. Examiner must be skillful in selecting the most appropriate test. Apart from those in the literature, we included all kinds of simulation in ophthalmology. In addition, simulation examination techniques, such as, use of optical coherence tomography, frequency doubling perimetry (FDP), and modified polarization tests were also included. In this review, we made a thorough literature search, and added our experiences to give the readers up -to -date information on malingering or simulation in ophthalmology. ·

Proton magnetic resonance spectroscopy of the anterior cingulate gyrus and caudate nucleus in schizophrenia patients versus healthy controls

引用

Neural Regeneration Research 2011年第6期6卷 467-473页

Proton magnetic resonance spectroscopy （^1 H-MRS） permits the assessment of cerebral neurometabolites, such as N-acetylaspartate, choline, and creatine, in vivo and has been used to study schizophrenia. The present study used ^1H-MRS to compare the spectroscopy change of N-acetylaspartate, creatine, and choline metabolite levels in the anterior cingulate and caudate nucleus of both schizophrenia patients and healthy controls, as well as between the left and right cerebral hemispheres in the schizophrenia patients. Results showed that N-acetylaspartate and creatine metabolite levels in the left anterior cingulate gyrus were significantly lower in the schizophrenia patients than in the healthy controls, indicating hypometabolism. In addition, choline concentration in the left caudate nucleus of schizophrenia patients was significantly lower than in the right caudate nucleus, indicating that it is necessary to study the cerebral lateralization of ^1H-MRS in schizophrenia patients.

Perioperative anesthetic management in pediatric hereditary angioedema;case report

引用

Open Journal of Pediatrics 2012年第4期2卷 294-297页

作者： M.Nuri Deniz Aylin incesu Elvan Erhan Gulden Ugur Ege University Medical Faculty IzmirTurkey

Hereditary angioedema is a rare but life-threatening disease, usually resulting from upper respiratory tract traumas and stress. In this case report, we present the management of a 14-year-old female patient who was diagnosed with hereditary angioedema and scheduled to undergo transurethral resection of bladder (TURB) procedure for bladder tumor. She was on prophylactic danazol treatment and prior to the operation the dose of danazol was increased. On the day of the operation, patient was given C1-IHN concentrate and was sedated. In conclusion, hereditary angioedema is a rare disease in which multidisciplinary and aggressive approach during anesthesia would yield successful results.
