Banking competition and risk-taking when borrowers care about financial prudence : [Version: Mai 2009]

Corporate borrowers care about the overall riskiness of a bank’s operations as their continued access to credit may rely on the bank’s ability to roll over loans or to expand existing credit facilities. As we show, a key implication of this observation is that increasing competition among banks should have an asymmetric impact on banks’ incentives to take on risk: Banks that are already riskier will take on yet more risk, while their safer rivals will become even more prudent. Our results offer new guidance for bank supervision in an increasingly competitive environment and may help to explain existing, ambiguous findings on the relationship between competition and risk-taking in banking. Furthermore, our results stress the beneficial role that competition can have for financial stability as it turns a bank’s "prudence" into an important competitive advantage

Central region morphometry in a child brain; Age and gender differences

Background: Data on central region morphometry of a child brain is  important not only in terms of providing us with information about central region anatomy of the brain but also in terms of the help of this  information for the plans to be applied in neurosurgery.Objective: In the present study, central region morphometry of a child  brain in mid.sagittal MR images was analyzed in age and gender groups.Materials and Methods: Different points determined previously,  commissura posterior (PC) and the distances between cerebral cortex point (VCS) vertical to commissura anterior. commissura posterior line, sulcus centralis (CS), sulcus marginalis (MS), and the angle (α) between   CS-PC-MS were determined and measured together with difference of gender in three different age groups (aged 6.9, 10.13, and 14.17).Results: Central region measures of the brains of boys aged 6.17 are  higher than girls except for MS.PC distance. While VCS.PC, CS.PC, and MS-PC measures display a significant difference in the girls aged 14.17  when compared to the other age groups of 6.9 and 10.13 (P < 0.05), angle α is not significantly different in age and gender groups (P > 0.05). However, while VCS-PC, CS-PC and MS-PC distances show a significant  increase in girls beginning from the age of 14, this increase is limited in boys.Conclusion: Morphometric differences observed in different age groups in boys and girls shall contribute our evaluation of the alterations in brain development in both of genders and shall be useful in preparation of  surgical operation plans to be applied to the central region.Key words: Brain, central region, child, morphometry, magnetic resonance Imagin

Determination of cerebellar volume in children and adolescents with magnetic resonance images

Recent studies show that the cerebellum contributes to higher cognitive functions as well as its role on motor system. It is thought that higher cognitive functions continue to develop during childhood and adolescence; therefore, cerebellum develops significantly during these periods. For that reason, this study was carried out in order to determine cerebellar volumes of 90 healthy individuals (40 males, 50 females) aged between 6 and 17 years according to their gender. The individuals were divided into three age groups of 6&#8211;9, 10&#8211; &#8211;13, and 14&#8211;17 years, and their cerebellar volumes were found by means of stereological methods using their magnetic resonance images. The cerebellar volumes found were compared among the groups without discriminating genders, among groups according to gender, and again according to gender within each age group. The general average cerebellar volume of the age group 10&#8211;13 years was significantly higher than the other two age groups (p < 0.05). When the groups were compared according to gender, there was no important difference between the groups in women (p > 0.05); as for men, cerebellar volume only in the age group 10&#8211;13 years was significantly higher than that in age group 6&#8211;9 (p < 0.05). When cerebellar volume for ages 6&#8211;17 years was compared according to gender (without dividing into age group) there was no significant difference between men and women (p > 0.05). It was seen that the cerebellum develops from childhood to adolescence, and reaches peak levels between the ages 10&#8211;13 years for both genders

Evaluation of the length and angulation of the styloid process in the patient with pre-diagnosis of Eagle syndrome

Clinical symptoms caused by the elongated styloid process (SP) or calcified stylohyoid ligament were first described by W. Eagle and they are now known as Eagle syndrome (ES). Normal length of SP was stated by Eagle as 2.5 cm. The objective of this study was to determine and discuss the length of SP and medial angulation degree with computed tomography (CT), which is an affective modality in the identification of ES, and a comparison with related studies. Three-dimensional (3D) images obtained from the axial CT scans of 22 cases (11 males and 11 females) aged between 24 and 80 years, who referred to Cumhuriyet University Hospital, Department of Radiology for multi slice CT with the pre-diagnosis of ES, were used. Lengths of the SP and medial angulations were measured on the obtained images. Inter- and intra-group comparisons were carried out using Wilcoxan and Mann-Whitney U tests. The mean length of the SP was found as 4.1 &#177; 1.1 cm. When inter- and intra-group lengths of the right and left SP were compared, the difference was not significant (p > 0.05). The mean medial angulation of the SP was found as 67.5 &#177; 5.1°. There was a significant difference found between the right side medial angulation and left side medial angulation in all persons (p < 0.05). Lengths of the right and left SP of the patients with pre-diagnosis of ES were close to each other. However, the right-side angulation was observed to be smaller than the left medial angulation in all the patients. Similarly, right side medial angulation of the females was smaller than the left side medial angulation, but this difference was absent in the males. Eagle syndrome should be kept in mind in patients with a sore throat radiating to the ears with swallowing and an observed non-compliance between the complaints such as feeling a foreign body in the throat and facial pain, and physical examination of those who do not have a response to long-term medical therapy should be performed.

International Society of Human and Animal Mycology (ISHAM)-ITS reference DNA barcoding database - the quality controlled standard tool for routine identification of human and animal pathogenic fungi

Human and animal fungal pathogens are a growing threat worldwide leading to emerging infections and creating new risks for established ones. There is a growing need for a rapid and accurate identification of pathogens to enable early diagnosis and targeted antifungal therapy. Morphological and biochemical identification methods are time-consuming and require trained experts. Alternatively, molecular methods, such as DNA barcoding, a powerful and easy tool for rapid monophasic identification, offer a practical approach for species identification and less demanding in terms of taxonomical expertise. However, its wide-spread use is still limited by a lack of quality-controlled reference databases and the evolving recognition and definition of new fungal species/complexes. An international consortium of medical mycology laboratories was formed aiming to establish a quality controlled ITS database under the umbrella of the ISHAM working group on "DNA barcoding of human and animal pathogenic fungi." A new database, containing 2800 ITS sequences representing 421 fungal species, providing the medical community with a freely accessible tool at http://www.isham.org and http://its.mycologylab.org/ to rapidly and reliably identify most agents of mycoses, was established. The generated sequences included in the new database were used to evaluate the variation and overall utility of the ITS region for the identification of pathogenic fungi at intra-and interspecies level. The average intraspecies variation ranged from 0 to 2.25%. This highlighted selected pathogenic fungal species, such as the dermatophytes and emerging yeast, for which additional molecular methods/genetic markers are required for their reliable identification from clinical and veterinary specimens.This study was supported by an National Health and Medical Research Council of Australia (NH&MRC) grant [#APP1031952] to W Meyer, S Chen, V Robert, and D Ellis; CNPq [350338/2000-0] and FAPERJ [E-26/103.157/2011] grants to RM Zancope-Oliveira; CNPq [308011/2010-4] and FAPESP [2007/08575-1] Fundacao de Amparo Pesquisa do Estado de So Paulo (FAPESP) grants to AL Colombo; PEst-OE/BIA/UI4050/2014 from Fundacao para a Ciencia e Tecnologia (FCT) to C Pais; the Belgian Science Policy Office (Belspo) to BCCM/IHEM; the MEXBOL program of CONACyT-Mexico, [ref. number: 1228961 to ML Taylor and [122481] to C Toriello; the Institut Pasteur and Institut de Veil le Sanitaire to F Dromer and D Garcia-Hermoso; and the grants from the Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq) and the Fundacao de Amparo a Pesquisa do Estado de Goias (FAPEG) to CM de Almeida Soares and JA Parente Rocha.

Geometric analysis of medio-lateral position of patella: A new measuring tool

Background: Evaluation of medio-lateral position of patella is necessary for diagnosis and treatment of patellofemoral diseases. Objective: In the present study, we aimed to evaluate medio-lateral patellar position differences and to define a new practical measuring tool which enables us to analyze relationships of the points at the knee. Materials and Methods: Total of 120 healthy volunteers (60 men and 60 women) were included in our study and both of their knees were measured. In the research, the gender groups and right-left differences were evaluated. In the measurements, a four-lever measuring tool designed for this study was used. The four anatomic points of the knee which are center of patella, epicondylus lateralis, epicondylus medialis and middle point of tuberositas tibiae were used. Results: While patella is 76% lateral in the right knee, it is 90% lateral in the left knee in men. As for woman, while it is 50% lateral in the right-knee, it is 30% lateral in the left-knee. In medio-lateral patellar position, while bilateral asymmetry is 28% in men, it is 50% in women. In measurements of knees of women and men, significant differences were detected both in the right and left knees (P < 0.05 and P < 0.001). Conclusion: The patellofemoral order differences between men and women can explain anatomic reasons of patellofemoral diseases, which are encountered more in women than men

Effect of increasing maximal aerobic exercise on serum gonadal hormones and alpha-fetoprotein in the luteal phase of professional female soccer players

[Purpose] The performance of female athletes during their menstrual period has attracted the attention of researchers for many years. It is known that the menstrual period changes with exercise. Alpha-fetoprotein (AFP) is an oncofetal protein. In this study, the effect of maximal aerobic exercise in the luteal phase on some hormones and AFP in female athletes was researched. [Subjects and Methods] Twelve volunteers and healthy female footballers with normal menstrual cycles volunteered for this study as subjects. All the participants performed a shuttle run test. Blood samples were taken before, after, and one hour after exercise. Serum AFP, estrogen, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) values were measured using an auto analyzer and original kits. Heart rate measurements were performed before and after the exercise. [Results] AFP activity had significantly decreased after 1 h of recovery from the exercise in the female soccer players, and estrogen and LH activity had significantly increased immediately after the exercise. Progesterone activity had significantly decreased immediately after the exercise. FSH values had significantly increased immediately after the exercise. [Conclusion] The results of the present study show there were significant decreases in the values of AFP, which is a cancer parameter, 1 hour after the exercise. This result may be valuable in future physiotherapy studies on the relationship between exercise and cancer
