64, 95% CI 0.52-0.79; p = 0.001), whereas no significant reduction of all-cause death (HR 0.77, 95% CI 0.44-1.35; p = 0.28) or cardiovascular death (HR 0.64, 95% CI 0.37-1.11; p = 0.09) was observed. CONCLUSIONS In STEMI patients without cardiogenic shock multivessel PCI reduced the risk of death or non-fatal reinfarction compared to culprit vessel-only PCI.The nucleosome is a small unit of chromatin, which is dynamic in eukaryotes. Chromatin conformation and post-translational modifications affect nucleosome dynamics under certain conditions, playing an important role in the epigenetic regulation of transcription, replication and reprogramming. The Snf2 remodeling family is one of the crucial remodeling complexes that tightly regulate chromatin structure and affect nucleosome dynamics. This family alters nucleosome positioning, exchanges histone variants, and assembles and disassembles nucleosomes at certain locations. Moreover, the Snf2 family, in conjunction with other co-factors, regulates gene expression in Saccharomyces cerevisiae. Here we first review recent findings on the Snf2 family remodeling complexes and then use some examples to illustrate the cooperation between different members of Snf2 family, and the cooperation between Snf2 family and other co-factors in gene regulation especially during transcription initiation.INTRODUCTION After transurethral resection of a bladder tumor, patients frequently have a recurrence of the disease, thereby requiring adjuvant therapy. PURPOSE The study aimed to determine the prognostic value of expression levels of p53, Ki-67, and survivin, and to develop a new prognostic model for patients with non-muscle-invasive bladder cancer (NMIBC) after transurethral resection of a bladder tumor. METHODS The study group consisted of 101 patients with primary NMIBC. Univariate followed by multivariate Cox proportional hazard regression analysis was performed to obtain a model including the smallest possible number of descriptive variables with the highest statistical significance and impact on risk. RESULTS The RECINT model (RECurrence In Not Treated) including factors independently associated with cancer recurrence (tumor size [HR 1.148; p = 0.034], intensity of the color reaction for p53 [HR 1.716; p = 0.008], Ki-67 [HR 3.001; p = 0.022], and survivin [HR 1.461; p = 0.021]) adequately stratified recurrence free-survival (R2 = 0.341, p  less then  0.001) in patients with primary NMIBC. Patients with the lowest RECINT score (0-6) had the lowest probability of cancer recurrence (1- and 5-year recurrence of 16%) in comparison with other groups (p  less then  0.001). see more CONCLUSIONS The RECINT model may be useful for stratifying the risk of recurrence in patients with non-muscle-invasive bladder cancer and may allow for identification of those who may benefit the most from adjuvant BCG immunotherapy.INTRODUCTION Adaptations to pathological intrauterine environment might differ in relation to fetal gender. We aimed to study sex-specific differences in placental pathology of pregnancies complicated by small for gestational age (SGA). METHODS The medical records and placental histology reports of all neonates with a birth-weight ≤ 10th percentile, born between 24 and 42 weeks of gestation, during 2010-2018, were reviewed. Composite neonatal outcome was defined as one or more of early following complications neonatal sepsis, blood transfusion, phototherapy, respiratory morbidity, cerebral morbidity, necrotizing enterocolitis, or death. Results were compared between the male and female groups of neonates. Placental lesions were classified into maternal and fetal vascular malperfusion (MVM and FVM) lesions, maternal and fetal inflammatory responses (MIR and FIR), and villitis of unknown etiology (VUE). RESULTS The male SGA group (n = 380) and the female SGA group (n = 363) did not differ in regard to maternal age, BMI, smoking, associated pregnancy complications, gestational age, and mode of delivery. Neonates in the SGA male group had increased birth-weight and increased respiratory morbidity as compared to the female SGA group (p = 0.007, p = 0.005, respectively). There was no between-group differences in the rate of placental lesions. By multivariate logistic regression analysis, male gender (aOR 1.55, 95% CI 1.05-2.30, p = 0.025), FIR (aOR 4.83, 95% CI 1.07-13.66, p = 0.003), and VUE (aOR 1.89, 95% CI 1.03-3.47, p = 0.04), were found to be independently associated with adverse composite neonatal outcome. DISCUSSION Male gender as well as placental FIR and VUE are independently associated with adverse neonatal outcome in SGA neonates.OBJECTIVE Exploration of changes in eye movement at different flight conditions can enrich scholarly understanding of situation awareness (SA) and inform new scanning behavior training techniques for efficient and effective pilot education. BACKGROUND The SA requirements for pilots vary from mission to mission. Eye tracking is often used to analyze various attention allocation and SA acquisition processes at work in different missions. METHODS Pilot eye movements were measured during a climbing task and circling task using a cockpit-based simulator. RESULTS Results of situation awareness rating technique (SART) tests show that there are significant differences between attention processes during climbing versus circling flight tasks. Fixation frequency during climbing is lower than in the circling task. Additionally, saccade frequency and average fixation time in the climbing task are markedly higher than those in the circling task. Wilcoxon test results show that the pilot has a higher fixation count and fixans accompanied by strict attention distribution, which yields high SA level and flight performance when performed properly. APPLICATION This paper summarizes the attention characteristics at different flight phases and various requirements of different tasks according to pilot eye movement tracking results. Similar activities, as routine training, can enhance the efficiency of a novice pilot's attention distribution.
