introduction: correct interpretation of kidney images requires the knowledge of its normal size. this study aimed to establish normal values for kidney length and parenchymal thickness and identify the potential related factors in a group of iranian adults. methods: renal dimensions, including length and parenchymal thickness were measured by sonography in 103 individuals with no renal disease....

Allometric growth pattern and body shape changes of the Green terror (Andinoacara rivulatus)(Cichlidae) were studied using landmark-based geometric morphometric (GM) and traditional methods, from hatching up to 1266 Hours Post Hatching (HPH) under culture conditions. The left side of specimens were photographed using digital camera and morphometric characters, including total length, head lengt...

We study the effects of scattering lengths on Lévy walks in quenched, one-dimensional random and fractal quasilattices, with scatterers spaced according to a long-tailed distribution. By analyzing the scaling properties of the random-walk probability distribution, we show that the effect of the varying scattering length can be reabsorbed in the multiplicative coefficient of the scaling length. ...

Introduction: The human stature forms part of his or her biological profile. It becomes more important during personal identification in case of mass disasters and in search of missing persons. We measured various parameters of the dried tibia, then by applying linear regression we formulated maximum tibia length which can be conveniently used for arriving at human stature. Methods: The obtain...

background & aim: dbs (deep brain stimulation) is a new and successful technique in treatment of symptoms of parkinsonism especially after drug resistance. research in this field is mostly designed for evolution of this technique. the present study aimed at evaluating the relationship between the angle formed in midsagittal and stn (sub-thalamic nucleus) axis line and recording length in the fi...

PURPOSE To evaluate whether oral fluid intake has an effect on renal length as determined with sonography. METHODS We studied 524 adult patients who were referred to our ultrasound unit with complaints other than urinary tract symptoms. The mean age of the patients was 44 years (range 17-76). All of the measurements were performed with the patient in the prone position. The renal length of ea...

background: long-term tunneled catheters are used for the hemodialysis or chemotherapy in many patients. proper placement of the catheter tip could reduce early and late catheter related complications. aim of the present study was to evaluate a new formula for proper placement of tunneled hemodialysis or infusion port device by using an external anatomic landmark. materials and methods: a total...

background and aims. various methods are used to measure the size and form of the teeth, including the golden proportion, and the width-to-length ratio of central teeth, referred to as the golden standard. the aim of this study was to evaluate the occurrence of golden standard values and golden proportion in the anterior teeth. materials and methods. photographs of 100 dentistry students (50 ma...

To better understand postural and movement disabilities, the pattern of total body muscle fat infiltration was analyzed in a large group of patients with facioscapulohumeral muscular dystrophy. Additionally, we studied whether residual D4Z4 repeat array length adjusted for age and gender could predict the degree of muscle involvement. Total body computed tomography scans of 70 patients were use...
