Abstract:

A 54-year-old female with pre-existing idiopathic moyamoya disease developed chest pain with acute myocardial infarction. Coronary angiography detected occluded and stenotic lesions in the coronary arteries. Right coronary artery stenosis was treated by balloon angioplasty and stenting. Because of the restenosis, on-pump cardiopulmonary bypass was performed. The operation was uneventful and no perioperative cerebral ischemic episode occurred. The conclusion is that on-pump cardiopulmonary bypass preserving intraoperative hemodynamic parameters at an optimal level is a safe procedure in a patient with moyamoya disease.

Abstract: Objectives: Epididymo-orchitis is a focal form of human brucellosis described in 2-20% of patients with brucellosis.Patients and Methods: In this retrospective study, the records of 190 adult male patients (mean age 27.5 years; range 17 to 71 years) with brucellosis were evaluated. Ten of these cases presented with epididymo-orchitis. Among these cases, epididymitis or epididymo-orchitis were diagnosed on the basis of a typical history of gradual onset of scrotal pain and findings of enlarged tender testes and/or epididymis. Results: The most common symptoms were fever, scrotal pain, and swelling (100%). There were different focal Brucellar involvements other than the epididymo-orchitis in eight patients (80%). All of the patients had unilateral epididymo-orchitis. A testicular abscess was detected in one patient. Combined antibiotic therapy was started and continued for 6-8 weeks. Orchiectomy was required for one patient (10%) and granulomatous orchitis was detected in the resected specimens. Relapse was not observed in any patient. Conclusion: Brucellosis should be considered in the diagnosis of scrotal diseases in endemic areas. Clinical and serological data are sufficient for the diagnosis. Conservative management combined with antibiotic therapy is adequate for managing brucellar epididymo-orchitis.

Abstract: In this study, age determination was done by using the skeletochronology method on Ak ehir, Konya (Turkey), 14 (5♂♂; 9♀♀) Parvilacerta parva specimens. Cross-sections of femurs were examined in total 14 individuals, the lowest number of LAGs was seen in one female and one male individuals as 4, the highest number of LAGs were seen in two female individuals as 8. Average SVL was found 50.8 mm (SD=2.27) in male individuals, and 53.1 mm (SD = 3.27) in females. For all the samples, the age-length equation was calculated as SVL (mm) = 37.82 + (2.47 * age). As a result of Pearson correlation analysis, a significant positive correlation (r=0.93, P 0.01) between age and SVL. Pileus length does not increase constantly with age (r=0.007, P=0.98), while pileus width increases normally together with age (r=0.212, P=0.46).

Abstract: Brucellosis is a zoonotic disease caused by Brucella species that is a gram negative coccobacilli and can cause symptoms such as fever, diaphoresis, arthalgia and myalgia. Although humans become infected by contact with animals or consuming dairy products that are contaminated with Brucella, cases in which humans are infected by vaccination are rarely mentioned in the literature. Here, we present the a case of a 24-year old veterinarian who was diagnosed with brucellosis upon being exposed to Brucella abortus S19 while vaccinating a young cattle and accidentally inoculating the pathogen to the thumb of his left hand. He was admitted to the Kocaeli zel Konak hospital 36 hours after the inoculation with an edema and sensitivity to pressure in the innoculation site, while the other physical examination findings were normal. At this stage theserological tests (Rose Bengal and agglutination) were negative, while the routin biochemical tests were within normal range. In addition, samples collected from the inoculation site didn’t show any bacterial growth. Despite chemoprophylactic treatment with doxycycline, the patient developed fever, diaphoresis, and testicular pain 21 days after the contact. His body temperature was 38.3 OC and the patient complained about pain when the finger was bended during his second visit. Laboratory tests showed the aspartat aminotransferaz (AST) level was 32 U/L, alanin aminotransferaz (ALT) 25 U/L, and CRP 8.94 mg/dL. The serological tests conducted later showed that the RoseBengal and the standard serum agglutination test werepositive at 1/320, while the blood culture was negative.Based on clinical and serological findings, the patientwas diagnosed with brucellosis and treated successfullya combination of doxycycline (200 mg/day) andrifampicin (600 mg/day) for six weeks. The followingexaminations didn’t show any symptoms and no relapsewas noted. Veterinarians are at risk to be infected withBrucella during vaccination, therefore those infectedshould receive prophylactic treatment. However, postexposure prophylactic treatment won’t always preventprogress of the disease and patients need to be followedup closely.

Bulletin of the Chemical Society of Ethiopia , 2011,
Abstract: A new kinetic method has been developed for the measurement of Mn(II) in water samples. The method is based on the catalytic effect of Mn(II) with the oxidation of Celestine blue (CB+) by KIO4 using 1,10-phenantroline (Phen) as an activator. The optimum conditions obtained are pH 4.5, 0.1 M acetate buffer solution, 4.0 x 10-4 M KIO4, 4.5 x 10-5 M CB+, 1.0 x 10-4 M Phen, reaction temperature 40 °C and reaction time of 4.0 min at 640 nm. Under the optimized conditions, the method allowed the measurement of Mn(II) in a range of 0.1-5.0 μg L-1 with a detection limit of 0.023 μg L-1. The recoveries in measuring the standard Mn(II) solutions of 0.5, 2.0 and 4.0 μg L-1 were in the range of 97-103%, and the relative standard deviations (RSDs) were in a range of 3.0-0.8%. The method was applied satisfactorily to the determination of Mn(II) in some environmental water samples. The reliability of method was also verified by determining the manganese content of the certified standard reference river water sample, JAC-0031. Compared with the previously published catalytic-kinetic methods and instrumental methods, the method showed fairly good selectivity and sensitivity, low cost, cheapness, low detection limit and rapidity. It can easily and successfully be applied to the natural water samples. KEY WORDS: Mn(II), Kinetic-spectrophotometry, Catalytic effect, 1,10-Phenantroline, Celestine blue Bull. Chem. Soc.

International Online Journal of Educational Sciences , 2012,
Abstract: The restructured primary education programs have different reflections on Turkish educational system and these reflections continue to be. A reflection of the renewed primary education programs has been noticed in exam for the transition to secondary school. A new exam under the name of Placement Test (SBS) has been applied since 2008. Compared with other tests, significant changes have been made within the scope of the SBS. One of these changes is to give place to the questions including images in SBS Turkish tests. When literature is reviewed, it is seen that there has been no research which analyzes the questions including images in SBS Turkish tests. The purpose of this study is to analyze the rate, diversity and content of the questions including images in SBS Turkish tests according to 6th, 7th and 8th class levels. With this purpose, SBS test booklets were analyzed using document review method which is one of the qualitative research approaches. The rate, diversity and content of the questions including images in SBS Turkish tests in the class level were determined by applying Miles and Huberman’s interactive model, coding and note-taking procedures and they were presented in findings of the research. According to the findings, it has been concluded that there is no standard in the rate by years and it was concentrated on them under specific headings in the range of variety and content. Provided that the results reached and recommendations made are taken into consideration, it is recommended that the images should be used in the new exam for transition to secondary school.
