The Effects Of Parenting Modes Of Our Middle Class On The Future Behavior Of Early Adolescents: A Behavioral Analytical Point Of View, Sabi̇ha Keski̇n Jan 2003

The Effects Of Parenting Modes Of Our Middle Class On The Future Behavior Of Early Adolescents: A Behavioral Analytical Point Of View, Sabi̇ha Keski̇n

Turkish Journal of Medical Sciences

Using the statements of 352 14-year-old early adolescents, 183 boys and 154 girls, with no history of conduct disorder, we surveyed the implications of how the behavior modification modes of our middle class will affect the future behavior of the subjects. Severe reprimand (53%), privilege removal (31%) and intense painful stimuli (12%) were the behavior managing modes used by the mother (53%), father (25%) or tutor (12%). The punishing effect (a decrease in the future frequency of the target behavior) of the above worsening conditions was only 8%, whereas the reinforcing effect (an increase in the future frequency of the …

A Novel Method Of Reporting C-Erbb-2 Overexpression; Correlation With Grade But Not With Other Prognostic Parameters In Breast Cancer, Mustafa Samur, Şeyda Karaveli̇, Hakan Bozcuk, Eli̇f Pestereli̇, Mustafa Özdoğan, Mustafa Yildiz, Mehmet Artaç, Burhan Savaş

Turkish Journal of Medical Sciences

Overexpression of erbB-2 protein is a marker of clinically aggressive behavior in breast cancer patients. In general erbB-2 status is reported on a scale from negative to 3+, depending on staining intensity, if more than 10% of the tumor cells are stained. However, the original definition does not take into account the percentage of stained cells in detail, since all samples score in the same way if they are above the cut-off, established at 10%. In this study, we evaluated the erB-B2 overexpression by immunohistochemistry in 169 patients and evaluated any correlation with the other well known prognostic parameters. We …

Determination Of Alkaline Phosphatase Activity In Patients With Different Zinc Metabolic Disorders, Zine Kechrid, Rabah Kenouz Jan 2003

Determination Of Alkaline Phosphatase Activity In Patients With Different Zinc Metabolic Disorders, Zine Kechrid, Rabah Kenouz

Turkish Journal of Medical Sciences

Our purpose was to investigate the effect of different zinc metabolic disorders on alkaline phosphatase activity. Serum zinc, glucose and alkaline phosphatase activity were studied in 32 patients with liver cirrhosis, 30 with chronic renal failure and 42 with insulin-dependent diabetes mellitus (IDDM) compared to 42 healthy volunteers. Serum glucose concentration was significantly higher (P < 0.001) in IDDM and liver cirrhosis patients (P < 0.05) compared to the controls. Serum zinc concentrations tended to be lower in all different diseases but did not reach statistical significance. Alkaline phosphatase activity was higher in IDDM (P < 0.05) and liver cirrhosis patients (P < 0.01) compared with the controls. No positive correlation between serum zinc and alkaline phosphatase activity was recorded in any disease. In conclusion, the investigated diseases did not affect the level of serum zinc; however, there was an alteration in alkaline phosphatase activity in patients suffering from diabetes and liver cirrhosis. Consequently, this may be attributed to the functional disturbance that occurred in these patients. Finally, zinc concentration did not follow alkaline phosphatase activity as indicated by the weak correlation obtained.

Pathophysiological Significance Of Blood Rheology, Oğuz Keri̇m Başkurt Jan 2003

Pathophysiological Significance Of Blood Rheology, Oğuz Keri̇m Başkurt

Turkish Journal of Medical Sciences

Tissue perfusion is determined by both blood vessel geometry and the rheological properties of blood. Blood is a non-Newtonian fluid, its viscosity being dependent on flow conditions. Blood and plasma viscosities, as well as the rheological properties of blood cells (e.g., deformability and aggregation of red blood cells), are influenced by disease processes and extreme physiological conditions. These rheological parameters may in turn affect the blood flow in vessels, and hence tissue perfusion. Unfortunately it is not always possible to determine if a change in rheological parameters is the cause or the result of a disease process. The hemorheology-tissue perfusion …

Isolation And Identification Of Phenolic Acids In Malaysian Honey With Antibacterial Properties, Almahdi Melad Aljadi, Kamaruddin Mohd Yusoff

Turkish Journal of Medical Sciences

In this study the non-peroxide antibacterial factors in Malaysian honey were isolated and identified. The phenolic components were extracted from two different local floral honeys and their effects on the growth of selected pathogens were examined. A solid-phase extraction procedure was applied for the first time to recover honey phenolics. Identification was carried out via high performance liquid chromatography and gas chromatography analysis. Antibacterial activity was determined via the disc-diffusion and broth dilution assays. The phenolic fractions of gelam and coconut honeys showed potent antibacterial activities. Both honeys contain gallic, caffeic, and benzoic acids. However, gelam honey contains additional phenolic …

Effects Of Acute Hypoxia On Body Substrate Utilisation During Progressively Increasing Work Rate Exercise Tests, Oğuz Özçeli̇k, Hali̇l Doğan, Haluk Keleşti̇mur Jan 2003

Effects Of Acute Hypoxia On Body Substrate Utilisation During Progressively Increasing Work Rate Exercise Tests, Oğuz Özçeli̇k, Hali̇l Doğan, Haluk Keleşti̇mur

Turkish Journal of Medical Sciences

Respiratory quotient (RQ) was used to assess the effectiveness of exercise interventions in shifting substrate utilisation. The body's RQ can be estimated non-invasively from the ratio of CO_2 production to O_2 consumption. In the present study, we examined the effects of acute hypoxia on the substrate utilisation of the body and its non-invasive estimation from ventilatory and pulmonary gas exchange variables during exercise. Eight male subjects performed two progressively increasing work rate exercise tests (15 W/min) until the limit of tolerance: in one test they were breathing room air (normoxia) and in the other 12% O_2 (hypoxia). Ventilatory and pulmonary …

Effects Of Ramadan Fasting On Stroke, Selçuk Çomoğlu, Ahmet Temi̇zhan, Emel Peşi̇nci̇, İzzet Tandoğan, Şenay Özbakir

Turkish Journal of Medical Sciences

The effects of fasting on humans have not been adequately investigated. Ramadan fasting is a great opportunity for scientific research due to its peculiar nature. With this in mind, we conducted research on the effects of Ramadan on stroke, which is one of the most common causes of death in adults. Patients hospitalized solely for ischemic stroke and intracerebral hemorrhage were evaluated retrospectively. The ratio of these cases to other patients hospitalized in the neurology department was determined. The in-hospital clinical course and mortality rates of the patients with stroke were evaluated. Within the entire cohort, the most frequently encountered …

Expression Of The Tumour Suppressor Gene P53 In Odontogenic Cysts, Ayla Özveren, Can Tuskan, Mehmet Yaltirik, Beli̇r Atalay, Gülçi̇n Erseven Jan 2003

Expression Of The Tumour Suppressor Gene P53 In Odontogenic Cysts, Ayla Özveren, Can Tuskan, Mehmet Yaltirik, Beli̇r Atalay, Gülçi̇n Erseven

Turkish Journal of Medical Sciences

The protein p53 seems to be related to the suppression of cell proliferation. Positive tissues appear to have a higher proliferative activity than negative tissues. Mutation of the p53 tumour suppressor gene has been demonstrated in a large proportion of human head and neck tumours, although no formal evidence of functional aberration has been shown p53 may have importance during the early stage of malignancy. The aim of this study was to evaluate the role of the p53 tumour suppressor gene in the pathogenesis of odontogenic cysts. Expression of abnormal p53 protein is a widely recognised marker of malignancy. Expression …

Tru-Cut And Fine Needle Aspiration Biopsy Diagnosis Of Lesions Of The Jaws, Namik Kemal Ayhan, Cengi̇zhan Keski̇n, Kerem Dedeoğlu, Mehmet Yaltirik

Turkish Journal of Medical Sciences

Nowadays, modern biopsy techniques such as fine and wide needles are used instead of invasive biopsy techniques for examining malign and benign lesions. This study examines whether wide needle biopsy (Tru-cut) possesses advantages as an alternative method to open biopsy. This study was performed on 40 patients with suspicious intra-jaw lesions. An 18-gauge, three-piece biopsy device was used. All the samples were sent to the tumor pathology unit at the oncology institute for histopathologic and cytopathologic examination. Thirty-seven of the 40 samples were adequate for diagnosis and three inadequate were. When we considered the results of Tru-cut and fine needle …

Turkish Journal of Medical Sciences

The hematopoietic stem cell transplant activity survey of the European Group for Blood and Marrow Transplantation (EBMT) represents a novel modern tool in health care management. Introduced in 1990, it captures annual numbers of hematopoietic stem cell transplantation (HSCT) by indication, donor type and stem cell source from each individual European transplant team. Supplemented by demographical data and economic factors, team density and transplant rates can be calculated and the impact of economics on HSCT rates can be assessed. As documented in the present analysis, a total of 19,668 HSCT were performed in Europe in 2001 by 599 teams in …
