The quantitative modeling of gene transcription and translation requires a treatment of two key features: stochastic fluctuations due to the limited copy numbers of key molecules (genes, RNA polymerases, ribosomes), and delayed output due to the time required for biopolymer synthesis. Recently proposed algorithms allow for efficient simulations of such(More)
OBJECTIVE Experimental data demonstrate that inflammation plays an important role in the initiation, progression, and complications of atherosclerosis. Statins were shown to downregulate inflammatory cytokines.We conducted this study to investigate the effects of fluvastatin therapy on plasma interleukin-18 (IL-18) and interleukin-10 (IL-10) concentration(More)
BACKGROUND Spine fractures are common. The treatment of traumatic fractures of the thoracic and lumbar spine remains controversial but surgery involving pedicle screw fixation has become a popular option. OBJECTIVES To assess the effects (benefits and harms) of pedicle screw fixation for traumatic fractures of the thoracic and lumbar spine. SEARCH(More)
We study a stochastic model of transcription kinetics in order to characterize the distributions of transcriptional delay and of elongation rates. Transcriptional delay is the time which elapses between the binding of RNA polymerase to a promoter sequence and its dissociation from the DNA template strand with consequent release of the transcript.(More)
The mammalian constitutive photomorphogenesis 9 (COP9) signalosome (CSN), a protein complex involved in embryonic development, is implicated in cell cycle regulation and the DNA damage response. Its role in tumor development, however, remains unclear. Here, we have shown that the COP9 subunit 6 (CSN6) gene is amplified in human breast cancer specimens, and(More)
BACKGROUND Exposure to polycyclic aromatic hydrocarbons (PAHs) is associated with reduced heart rate variability (HRV), a strong predictor of cardiovascular diseases, but the mechanism is not well understood. OBJECTIVES We hypothesized that PAHs might induce systemic inflammation and stress response, contributing to altered cardiac autonomic function. (More)
Pathogenesis-related proteins (PR), including beta-1,3-glucanases may provide the first line of defense against fungal pathogens. Many PR proteins are activated by salicylic acid (SA), which acts as an endogenous signal. We have previously isolated seven members of the beta-1,3-glucanase gene family in barley (Hordeum vulgare). In this paper, we(More)
Spontaneous abortion is the most common complication of pregnancy. Immune activation and the subsequent inflammation-induced tissue injury are often observed at the maternal-fetal interface as the final pathological assault in recurrent spontaneous abortion. However, the precise mechanisms responsible for spontaneous abortion involving inflammation are not(More)
Polymeric synthetic mimics of antimicrobial peptides (SMAMPs) have recently demonstrated similar antimicrobial activity as natural antimicrobial peptides (AMPs) from innate immunity. This is surprising, since polymeric SMAMPs are heterogeneous in terms of chemical structure (random sequence) and conformation (random coil), in contrast to defined amino acid(More)
BACKGROUND After total sacrectomy, it is mandatory to reconstruct the continuity between the lumbar spine and the pelvis. Only few biomechanical analyses exist which compare different reconstructions. Therefore, the aim of this study was to compare the lumbo-pelvic motion and the relative risk of implant breakage for four different reconstructions after(More)
