OBJECTIVE Low dose radiation may stimulate the growth and development of animals, increase life span, enhance fertility, and downgrade the incidence of tumor occurrence.The aim of this study was to investigate the antitumor effect and hormesis in an erythrocyte system induced by low-dose radiation. METHODS Kunming strain male mice were subcutaneously implanted with S180 sarcoma cells in the r...

scientific evidence regarding the efficacy and safety of the ldm approach in the treatment of psoriasis vulgaris, and positive preliminary data regarding the oral administration of low dose activated cytokines for vitiligo and atopic dermatitis treatment, support the ldm-based therapeutic approach for many dermatological diseases. ldm suggests the use of low-doses of activated biological molecu...

AIMS Presence of contractile reserve during low-dose dobutamine stress echo (DSE) appears predictive of cardiac resynchronization therapy (CRT) outcome. We hypothesize that changes in left bundle branch block (LBBB)-induced dyssynchronous motion during low-dose DSE could be related to the extent of reverse remodelling. METHODS AND RESULTS Fifty-two patients (69 +/- 2 years, EF: 24 +/- 7%, QRS...

the frequency of chromosomal aberrations was studied in the peripheral blood lymphocytes of 65 radiology technologists crt) working at hospitals chronically exposed to x-rays. although film dosimetry did not show the maximal annual permitted dose in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal aberrations in r t compared to unexposed controls. th...

BACKGROUND Erythropoietin (Epo) is an effective but expensive treatment for anaemia in patients with chronic renal failure. Hyporesponsiveness to Epo, particularly in haemodialysis patients, is most commonly due to a functional iron deficiency, which is difficult to monitor reliably. METHODS Forty-six stable haemodialysis patients, receiving Epo therapy, were commenced on regular low-dose int...

the adaptive response (ar) is a phenomenon by which cells exposure to sublethal doses of dna-damaging agents (non-mutagenic dose of chemical or radiation), known as conditioning treatment (ct), leads to increased resistance to a subsequent exposure to a higher dose of the same or other agents, known as challenge treatment (cr). the adaptive response (ar) induced by radiation in human lymphocyte...

conclusions modern cts with the innovative technology of a built-in tin filter allow for significant reduction of radiation exposure in patients with suspected urolithiasis by optimizing the x - ray spectrum with image quality as high as in standard ct devices results ct examinations of a total of 143 patients were assessed. dlp of force was 56% and 55% lower in comparison to as+ and flash, (74...
