Effects of experimental diabetes and insulin treatment on rabbit renal morphology: A quantitative and qualitative study
(2001)
Diabetes causes metabolic defects and related vascular alterations such as atherosclerosis. These vascular alterations may also reflect the renal structural degeneration under the influence of diabetes. Therefore, the aim ...
Gypsum/anhydrite: Some engineering problems
(2001)
The engineering properties of gypsum/anhydrite change as a consequence of groundwater, pressure and heat. Gypsum and anhydrite may experience dissolution in the near-surface zone and along the discontinuities, creating ...
Possible Role of K-ras Oncogene in Mutagenic Activity of Ethylnitrosourea on Lymphocyte Hyperproliferation in Rat Colon
(2001)
N-ethyl-N-nitrosourea (ENU) is a potential carcinogenic agent that is commonly used in industry. Therefore the present study aimed to find out the possible effects of this agent on the rat digestive tract especially on the ...
K-Ras mutation in transitional cell carcinoma of urinary bladder
(2001)
In the present study it was aimed to investigate the frequency of K-RAS mutation in the human bladder transitional cell carcinoma. For this purpose, tissue specimens obtained from the patients with bladder tumors. Genomic ...
On the centroid of the prime gamma rings II
(2001)
The aim of this paper is to study the properties of the extended centroid of the prime ?-rings. Main results are the following theorems: (1) Let M be a simple ?-ring with unity. Suppose that for some a ? 0 in M we have ...
?m-statistical convergence
(2001)
In this paper, we define a general sequence space ?m (X) = {x = (xk) : (?m xk) ? X}, (m ? N), where X is any sequence space. We establish some inclusion relations, topological results and we characterize the continuous ...
Possible role of DNA hypomethylation in mutagenic activity of N'-ethyl-N'-nitrosourea (ENU) on subcutaneous rhabdomyosarcoma in rat
(2001)
Purpose: The aim of the study was to find out the possible effects of DNA hypomethylation on N'-ethyl-N'-nitrosourea (ENU) mutagenity. Methods: Rats were injected with 300mg/kg body weight-body weight ENU (i.p.)for 45 weeks ...
Determination of the absorption of Zn by preterm infants, using 70Zn enriched tracer
(2001)
Absorption of zinc by preterm infants from a synthetic milk labelled extrinsically with 70Zn tracer was determined by faecal monitoring. Six male preterm babies with a mean gestational age of 31±2.9 weeks and a mean birth ...
Rapid diagnosis of catheter related sepsis in hemodialysis patients
(2001)
Purpose: To distinguish between infected and non-infected Central Venous Catheters (CVCs) applied to hemodialysis patients without having to wait bacterial cultures, we evaluated the importance of sera C-Reactive Protein ...
Non-linear dynamics in a graded quantum well placed in a GaAlAs p-n junction
(2001)
Theoretical and experimental results concerning the study of a novel wavelength converter amplifier, which can be tuned, with the amplification of an external voltage are presented. The device consists of a Ga1-xAlx As ...
