Background The increased mortality after hospitalization for decompensated heart failure (HF), where diuretics are usually intensified. It is not clear how risk is affected after the intensification outpatient diuretic therapy for HF.
Methods and Results From the national administrative registers, we identified all patients diagnosed with HF Denmark 2001-2016 and received an angiotensin-converting enzyme inhibitors / angiotensin receptor blockers and β-blockers within 120 days. Next follow-up tracked events progressive intensification diuretic and HF hospitalization. Intensification of events defined as a new addition or doubling of the loop diuretics or thiazide diuretics increase the loop. This event is included in the multivariable Cox regression models, calculating the danger of death one year after each year since inclusion.
Patients with intensification events or hospitalizations set risk-adjusted with two control HF nonworsened and 1 year absolute risk of death was calculated using Kaplan-Meier estimates. We included 74 990 patients, their average age was 71 years, and 36% are women. Intensification of events associated with a significantly increased mortality at any time during follow-up. one-year mortality was 18.0% after the intensification, 22.6% after HF hospitalization, and 10.4% for the control fits nicely.
In multivariable Cox models adjusted for age, sex, ischemic heart disease, atrial fibrillation, chronic obstructive pulmonary disease, and diabetes mellitus, the hazard ratio for death of 1 year after the intensification of events was 1.75 (95% CI, 1.66 to 1 , 85), and it was 2.28 (95% CI, 2.16 to 2.41) after HF hospitalization. Conclusion In a nationwide cohort of patients with HF, outpatient intensification events associated with almost 2-fold risk of mortality over the next year. Although HF hospitalization was associated with a higher risk, the need to intensify diuretics in an outpatient setting is a signal to review and intensify its efforts to improve HF outcomes.
One-Year Mortality After Intensification of Outpatient Diuretic Therapy
Perfusion approach an alternative to intensification of Virus-Like Particle Production in HEK293 Culture
Virus-like particles (VLP) has gained interest over the last year as the format of a recombinant vaccine, because they produce a strong immune response and the storage and distribution of present advantages over conventional vaccines. Therefore, VLP vaccine is being considered as a potential candidate for several diseases. One of the requirements for further clinical testing they are scalable and platform development process for the production of cell-based viral particles.
In this work, methods of gene expression extended (EGE), which consists in the replacement of the media that successive combined with retransfections cells, successfully optimized and transferred to the perfusion bioreactor operation. An optimization process using design of experiments (DoE) was conducted to obtain the optimal value for the current retransfection, a certain degree of perfusion cell (CSPR) and the concentration of transfected DNA, increasing 86.7% as previously reported in HEK293 EGE protocol.
Description: Transcription factor that can activate or repress transcription in response to physiological and pathological stimuli. Binds with high affinity to GC-rich motifs and regulates the expression of a large number of genes involved in a variety of processes such as cell growth, apoptosis, differentiation and immune responses. Highly regulated by post-translational modifications (phosphorylations, sumoylation, proteolytic cleavage, glycosylation and acetylation). Binds also the PDGFR-alpha G-box promoter. May have a role in modulating the cellular response to DNA damage. Implicated in chromatin remodeling. Plays a role in the recruitment of SMARCA4/BRG1 on the c-FOS promoter. Plays an essential role in the regulation of FE65 gene expression. [UniProt]
Description: SP1 (transcription factor Sp1), also known as Specificity Protein 1, is a human transcription factor involved in gene expression in the early development of an organism. It belongs to the Sp/KLF family of transcription factors. The protein is 785 amino acids long, with a molecular weight of 81 kDA. By fluorescence in situ hybridization, Matera and Ward (1993) mapped the SP1 gene to 12q13. By in situ hybridization, Gaynor et al. (1993) concluded that 12q13.1 is the most probable location of the SP1 gene. Segmentation in Drosophila is based on a cascade of hierarchical gene interactions initiated by maternally deposited morphogens that define the spatially restricted domains of gap gene expression at blastoderm. The formation of 7 head segments depends on the function of several genes. Wimmer et al. (1993) showed that one of these genes is the Drosophila homolog of the human transcription factor SP1.
Description: The protein encoded by this gene is a zinc finger transcription factor that binds to GC-rich motifs of many promoters. The encoded protein is involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. Post-translational modifications such as phosphorylation, acetylation, glycosylation, and proteolytic processing significantly affect the activity of this protein, which can be an activator or a repressor.

Post-translational modifications such as phosphorylation, acetylation, glycosylation, and proteolytic processing significantly affect the activity of this protein, which can be an activator or a repressor. Three transcript variants encoding different isoforms have been found for this gene.
