PURPOSE To determine the analgesic efficacy of percutaneous vertebroplasty in treating osteoblastic and mixed spinal metastases. MATERIALS AND METHODS Fifty-two patients underwent 59 vertebroplasty procedures for 103 painful vertebral metastases, among which 53 were pure osteoblastic and 50 were mixed (blastic and lytic). Analgesic efficacy was classified as "excellent," "good," "fair," and "...
In the current study, we evaluated various robust statistical methods for comparing two independent groups. Two scenarios for simulation were generated: one of equality and another of population mean differences. In each of the scenarios, 33 experimental conditions were used as a function of sample size, standard deviation and asymmetry. For each condition, 5000 replications per group were gene...
background: improvement of attitudes toward breast cancer positively affects the screening behaviors of women. imagery has been shown to have a positive impact on the screening behaviors of women. aim: this study aimed to investigate the effects of breast cancer screening training based on the systematic comprehensive health education and promotion (shep) model on the attitudes and breast self-...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
Klíčová slova oligoklonální pásy – mozkomíšní mok – IgG index – roztroušená skleróza Abstract Objective: The aim of this study was to assess the correlation between IgG index values and the number of the oligoclonal IgG bands (OCB) in the cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS). Material and Methods: The set of 150 patients consisted of 41 males and 109 females (aged ...
BRCA1 mutation carriers face a high lifetime risk of developing breast cancer. Physical activity induces broad transcriptional changes, and multiple studies have documented its beneficial effects across cancers. Because haploinsufficiency predisposes to breast cancer in these women, factors that increase BRCA1 levels may mitigate the effect of the mutation. Whether physical activity modulates B...
AIMS The aim of this study was to assess the correlation between IgG index values and the number of the oligoclonal IgG bands (OCB) in the cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS). MATERIAL AND METHODS The set of 150 patients consisted of 41 males and 109 females (aged 18-68, mean 36.6 +/- 10.1 years). The CSF collected by a lumbar puncture was examined evaluating in...
The physics of the strong interactions always has been tightly connected to the study of nucleons at shorter and shorter distances. The measurement of the anomalous magnetic moments of the proton and neutron in 1933 and 1939 made clear that nucleons are no elementary particles. During the 1950ies the Hofstadter experiments revealed the charge distributions inside nucleons at scales Q ≃ 0.5 ·M N...
