Parametric analysis of drug distribution during infusions into the brain using an axisymmetric model with backflow

Convection-enhanced delivery as a means to deliver therapeutic drugs directly to the brain has shown limited clinical efficacy, primarily attributed to the phenomena of backflow, in which the infused fluid flows preferentially along theshaft catheter rather than forward into the tissue. We have previously developed a finite element model of backflow that includes both material and geometric nonlin

Embedded 3D Printing in Self-Healing Annealable Composites for Precise Patterning of Functionally Mature Human Neural Constructs

Human in vitro models of neural tissue with tunable microenvironment and defined spatial arrangement are needed to facilitate studies of brain development and disease. Towards this end, embedded printing inside granular gels holds great promise as it allows precise patterning of extremely soft tissue constructs. However, granular printing support formulations are restricted to only a handful of ma

Compensation after umbilical hernia repair : prosthesis and non-prosthesis claims

Based on solid evidence, mesh prosthesis reinforcement has reduced the risk of recurrence after umbilical hernia repair1–4, but less is known about the risk of complications or chronic pain4,5. Patients’ claims after surgery may represent a surrogate for poor outcome6. This study examined mesh prosthesis-related complications leading to economic compensation after elective umbilical hernia repair.

Cerebral Microdialysis-Based Interventions Targeting Delayed Cerebral Ischemia Following Aneurysmal Subarachnoid Hemorrhage

Background: Delayed cerebral ischemia (DCI), a complication of subarachnoid hemorrhage (SAH), is linked to cerebral vasospasm and associated with poor long-term outcome. We implemented a structured cerebral microdialysis (CMD) based protocol using the lactate/pyruvate ratio (LPR) as an indicator of the cerebral energy metabolic status in the neurocritical care decision making, using an LPR ≥ 30 as

Parental decisions to divorce and have additional children among families with children with cerebral palsy : Evidence from Swedish longitudinal and administrative data

This study analyzes the relationship of having a child with the early-onset disability cerebral palsy (CP) and the parental decision to divorce and to have additional children. We use longitudinal matched case-control data from multiple linked Swedish National Population Registers between 2001 and 2015 and perform Cox proportional hazards regressions with interval-censoring. Although we do not fin

An ecofeminist position in critical practice: Challenging corporate truth in the Anthropocene

Drawing on selected discourses of non-essentialist ecofeminism, this article proposes and substantiates an ecofeminist position. This distinct position is shown to bring with it a capacity to challenge widely uncontested, corporate-produced truths regarding the benefits and the legitimacy of certain commercial activities. Three historical cases inform the discussion: the fights led by Rachel Carso

Early history of skin preservation and transplantation; the role of Carl August Ljunggren

During the late 19th and the early 20th century there was an unprecedented development in medical research. Tissue and cell culture rapidly developed into areas with many contributing scientists. The same is true for tissue transplantation. When these achievements are described afterwards in a historical context and a mainline development is constructed, there are researchers whose pioneering work

Being innovative, fun, and green? Hedonic and environmental motivations in the use of green innovations

This paper seeks to determine the decision-making route relating to hedonic and environmental motivation in green innovation adoption and to show how two similar green innovations can motivate consumers differently. It also aims to determine the effect of domain-specific innovativeness (DSI) on emotions and green identity on environmental motivations. The paper focuses on two types of green transp

Reproductive Health in Chronic Kidney Disease : The Implications of Sex and Gender

Chronic kidney disease (CKD) is frequently accompanied by reproductive health challenges in females and males alike. Progression of CKD is associated with escalating impairment of the hypothalamic–pituitary–gonadal axis, which facilitates evolving ovarian, testicular, and sexual dysfunction. Common clinical reproductive health complications in CKD include abnormal menstruation, impaired sexual hea

In situ X-ray reflectivity and GISAXS study of mesoporous silica films grown from sodium silicate solution precursors

An environmentally friendly and inexpensive silica source, sodium silicate solution, was applied to synthesize a free-standing mesoporous silica film at the air/liquid interface, exploiting the co-assembly of cetyltrimethylammonium bromide and polyethylenimine. The effect of the composition of the solution used for the film formation on the mesostructure of the as-synthesized silica films, charact

Polygenic scores, diet quality, and type 2 diabetes risk : An observational study among 35,759 adults from 3 US cohorts

Background Bothgenetic and lifestyle factors contribute to the risk of type 2 diabetes, but the extent to which there is a synergistic effect of the 2 factors is unclear. The aim of this study was to examine the joint associations of genetic risk and diet quality with incident type 2 diabetes. Methods and findings We analyzed data from 35,759 men and women in the United States participating in the

A somatic mutation in moesin drives progression into acute myeloid leukemia

Acute myeloid leukemia (AML) arises when leukemia-initiating cells, defined by a primary genetic lesion, acquire subsequent molecular changes whose cumulative effects bypass tumor suppression. The changes that underlie AML pathogenesis not only provide insights into the biology of transformation but also reveal novel therapeutic opportunities. However, backtracking these events in transformed huma

Observation of a linked-loop quantum state in a topological magnet

Quantum phases can be classified by topological invariants, which take on discrete values capturing global information about the quantum state1–13. Over the past decades, these invariants have come to play a central role in describing matter, providing the foundation for understanding superfluids5, magnets6,7, the quantum Hall effect3,8, topological insulators9,10, Weyl semimetals11–13 and other p
