e., 20 L pre-stage perfusion and 80 L production reactor. Moreover, an earlier shift from a growth associated to a production stage associated gene expression pattern was identified for uHSD cultures compared to the reference. Overall, we showed that the described intensification strategy yielded in a higher volumetric productivity and is applicable for existing or already approved molecules in common, commercial fed-batch facilities. This work provides an in-depth molecular understanding of cellular processes that are detrimental during process intensification.In the present study, the production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) by Azotobacter vinelandii was evaluated in shake flasks and bioreactors, utilizing different precursors and oxygen transfer rates (OTRs). In shake flask cultures, the highest PHBV yield from sucrose (0.16 g g-1) and 3-hydroxyvalerate (3HV) fraction in the PHA chain (27.4 mol%) were obtained with valerate (1.0 g L-1). Epigenetics inhibitor In the bioreactor, the cultures were grown under oxygen-limited conditions, and the maximum OTR (OTRmax) was varied by adjusting the agitation rate. In the cultures grown at low OTRmax (4.3 mmol L-1 h-1), the intracellular content of PHBV (73% w w-1) was improved, whereas a maximum 3HV fraction (35 mol %) was obtained when a higher OTRmax (17.2 mmol L-1 h-1, to 600 rpm) was employed. The findings obtained suggest that the PHBV production and the content of 3HV incorporated into the polymer were affected by the OTR. Based on the evidence, it is possible to produce PHBV with a different composition by varying the OTR of the culture; thus, the approach in this study could be used to scale up PHBV production.The formation of the World Federation of Associations of Pediatric Surgery (WOFAPS) was an important unifying force in the emergence of pediatric surgery as a distinct specialty. Beginning with the formation of several national societies in the early '60s, an early, multinational effort was created. This was in large part fostered by the International Pediatric Association (IPA), which lent logistical support from the medical pediatric community to the pediatric surgeons. In 2001, the mission of the Federation was formalized to focus on the development and education of surgeons serving children, in all parts of the world. This was articulated in the famous Kyoto Declaration of Pediatric Surgery "Every infant and child who suffers from an illness or disease has the right to be treated in an environment devoted to their care by a pediatric medical or surgical specialist". This vision was unique at the time and foreshadowed the major increase in advocacy activity which has emerged in recent years. While the mission has evolved with time, the present organization continues to hold true to the guiding principles of the original founders and seeks to improve the quality of "Surgical Care for the child, no matter where they live". Education and collaboration across borders underpins the organization's endeavors.Infertility and endocrine late effects (LE) are common sequelae after pediatric allogeneic hematopoietic stem cell transplantation (HSCT) after myeloablative conditioning. Nevertheless, the individual risk for these LE is not always easy to predict and therefore these issues are of ongoing interest to the clinical research community dealing with HSCT aftercare. This article describes the case of a young woman who received polychemotherapy and total body irradiation (TBI) containing conditioning for HSCT for a relapsed anaplastic large cell lymphoma (ALCL). She developed severe sclerotic chronic graft-versus-host disease (GVHD) with irreversible joint contractures and multiorgan involvement, requiring long-term multimodal immunosuppressive treatment. Subsequently showing a considerable number of LE including hypergonadotropic hypogonadism, she accepted that infertility would be quite likely. Her courageous personal life planning included part-time working and a partnership but not motherhood. This article reports the unexpected and spontaneous pregnancy and the extreme preterm birth of a surprisingly adequately developing child.Soil animals play important roles in ecosystem functioning and stability, but the environmental controls on their communities are not fully understood. In this study, we compiled a dataset of soil animal communities for which the abundance and body mass of multiple soil animal groups were recorded. The mass-abundance scaling relationships were then used to investigate multiple environmental controls on soil animal community composition. The data reveal latitudinal shifts from high abundances of small soil animals at high latitudes to greater relative abundances of large soil animals at low latitudes. A hierarchical linear mixed effects model was applied to reveal the environmental variables shaping these latitudinal trends. The final hierarchical model identified mean annual temperature, soil pH and soil organic carbon content as key environmental controls explaining global mass-abundance scaling relationships in soil animal communities (R2c = 0.828, Ngroup = 117). Such relationships between soil biota with climate and edaphic conditions have been previously identified for soil microbial, but not soil animal, communities at a global scale. More comprehensive global soil community datasets are needed to better understand the generality of these relationships over a broader range of global ecosystems and soil animal groups.Extensive branching creates the complex dendritic arbor of mammalian CNS neurons but capturing the complete process of branch formation with time-lapse recordings has been challenging. Here, we report that application of BMP7 to cultured hippocampal neurons accelerated dendritic growth sufficiently to document branches forming in less than 20 h via frequent time-lapse imaging (10-min intervals). In these recordings, most branches emerged as collateral sprouts from the shaft of a parent branch. Analysis of the recordings showed that filopodia were abundant and formed transiently throughout the length of dendrites but among these, only a small subset occurred at sites where branches later emerged. Conversely, formation of lamellipodia was rare and coincided with sites where collateral branches emerged. This pattern suggests that lamellipodial structures act as an important intermediate form of cytoskeletal remodeling related to a cellular commitment to branch, whereas filopodia appear to be related to events prior to such commitment.
