Pairwise key distribution among the sensor nodes is an essential problem for providing security in Wireless Sensor Networks (WSNs). The common approach for this problem is random key predistribution, which suffers from resiliency issues in case of node captures by adversaries. In the literature, the resiliency problem is addressed by zone-based deployment(More)
The majority of studies on security in resource limited wireless sensor networks (WSN) focus on finding an efficient balance among energy consumption, computational speed and memory usage. Besides these resources, time is a relatively immature aspect that can be considered in system design and performance evaluations. In a recent study(Castelluccia and(More)
OBJECTIVE To determine possible acute kidney injury with new marker neutrophil gelatinase-associated lipocalin (NGAL) in urine and to show the relationship between changes of this marker and conventional markers in patients undergoing shock wave lithotripsy (SWL). METHODS In patients with kidney stones, serum urea, creatinine, urine microalbumin, and NGAL(More)
OBJECTIVE To evaluate the 2 methods of cytologic screening to detect abnormalities of the cervical epithelium. METHODS This study with 3 groups of women was performed at Selcuk University Meram Medical School between January 2004 and March 2006. In one group (paired sample for specimen collection) women were screened with conventional cytology; in another(More)
We aimed to investigate bladder cancer risk with reference to polymorphic variants of cytochrome p450 (CYP) 1A1, CYP1B1, glutathione S-transferase (GST) M1, and GSTT1 genes in a case control study. Polymorphisms were examined in 114 bladder cancer patients and 114 age and sex-matched cancer-free subjects. Genotypes were determined using allele specific PCR(More)
24 adult patients suffering from Adult periodontitis were assigned to 4 groups: the 1st rinsed for 1 min with 0.2% chlorhexidine gluconate (CHX); the 2nd group were irrigated for 15 s with 0.2% CHX in a pulsed oral irrigator; the 3rd group rinsed for 1 min with saline and the 4th group were irrigated for 15 s with saline. Plaque vitality was measured after(More)
PURPOSE Genital development is affected by pubertal process to a great extent, and puberty is a complex phenomenon that is influenced by multiple factors resulting in individual differences. We studied penile length and its relationship to pubertal stage in boys 13 to 15 years old. MATERIALS AND METHODS Healthy boys who were candidates for military high(More)
The periodontal status of 77 diabetic children and adolescents, and 77 paired, systemically-healthy, sex- and age-matched control subjects, was clinical examined. Fasting blood glucose, fructosamine and glycosylated haemoglobin (HbA1) values were determined. The mean periodontal pocket depths, clinical attachment levels and the parameters to assess diabetes(More)
OBJECTIVE To investigate the relationship between depth of maxillopalatal arch and deviation of posterior septum. METHODS This study is based on paranasal sinus CT (PNSCT) scan in the coronal plane evaluation, and sinus paranasal scans were obtained from the database. One-hundred and fifty PNSCT scans were randomly chosen among the PNSCT scans which(More)
OBJECTIVES Obesity is an important risk factor for the development of colorectal cancer (CRC). Although the impact of bariatric surgery on CRC is conflicting, its impact on precursor lesions is unknown. The aim of this study was to determine whether bariatric surgery before index screening colonoscopy is associated with decreased development of colorectal(More)
