Purpose: Forehead flaps are commonly used in oculoplastic surgery to cover defects after tumor excision. Blood perfusion is vital for flap survival. The aim of this study was to monitor the perfusion in forehead flaps and investigate the impact of flap length and thickness. Methods: Nineteen forehead flaps in patients undergoing direct brow lift were studied. Perfusion was monitored using laser sp
Since 1958, cell culture media supplemented with fetal bovine serum is used, despite the well-known concerns about animal welfare, reproducibility, reliability, relevance, and safety. To obliterate these concerns and increase scientific accuracy, we recently published an open access, publicly available paper on a defined medium composition to make it possible for any lab to prepare this medium. Th
Background: Congestion is associated with poor prognosis in cardiac amyloidosis (CA). The cardio-hepatic interaction and the prognostic impact of secondary liver affection by cardiac congestion in CA are poorly understood and require further characterisation. Methods: Participants of the amyloidosis cohort study AmyKoS at the Interdisciplinary Amyloidosis Centre of Northern Bavaria with proven tra
We tested the chondrogenic potential of demineralized allogeneic bone matrix (DABM) in the repair of osteochondral defects. In 42 adult rabbits, a 5-mm2 or 15-mm2 defect was created bilaterally in the intercondylar groove of distal femur. DABM was inserted directly in 37 defects, whereas in 35 it was inserted after previous placement in muscle for 4, 16, or 19 days. Another 12 defects were left em
Purpose: Ultrahypofractionated (UHF) radiation therapy (RT) has become a treatment alternative for patients with localized prostate cancer. In more advanced cases, seminal vesicles (SVs) are routinely included in the target volume. The Scandinavian HYPO-RT-PC trial, which compared 42.7 Gy in 7 fractions (fr) to conventional fractionation (CF), did not include SVs in the clinical target volume. The
The continued increased exposure to chemicals and the increasing prevalence of allergic contact dermatitis makes it important to develop accurate testing methods and strategies to assess chemical sensitizers. The Genomic Allergen Rapid Detection (GARD) assay is an in vitro test method that uses the transcriptional response of a myeloid cell line, MUTZ-3, after exposure to test substances to assess
Sierra Leone has struggled with high rates of adolescent pregnancy for some time and reports have shown an increase in these figures during and following the unprecedented Ebola Virus Disease outbreak from 2014 through 15. As young girls are impregnated, it has long been customary for girls to drop out of school. When schools re-opened after the Ebola crisis, this practice was formalized as the Mi
The study of home has historically been approached by numerous academic disciplines within the social sciences and humanities. However, increased international mobility and forced migration due to conflict in recent years has produced a renewed interest to understand the ways we conceptualize and (re)create home in foreign places. The present research aims to produce a theoretical framework that a
The Andes of Ecuador are known for an outstanding biodiversity but is also a region where the abandonment rate of agricultural land is high, highlighting the need for forest restoration with native species. Here, the germination and growth requirements for propagation of the hummingbird pollinated bush species Salvia corrugata and Macleania rupestris were studied to better understand their suitabi
As the industrial, commercial, and domestic prevalence of Internet of Things networks grows, so does the search for viable solutions to decrease their energy consumption. One common solution is using a low-power proxy that can control the power state of the devices within the network. To evaluate such solutions, either implementations can be made and measured for energy consumption, or energy mode
The Chittagong Hill Tracts (CHT) of Bangladesh was full of natural resources like water, river, forest, agriculture, land. Various agencies like government and non-government (local, national, and international) have undertaken and implemented development programs in the CHT at different times encompassing those natural resources to develop the CHT economy and contribute to the overall economic
The thesis aims to investigate the role of local lead firms in the transformation of smallholders’ technological capabilities towards sustainable agriculture production through the lens of global value chain governance. The technological capabilities that help smallholders adopt and apply sustainable agriculture practices and comply with sustainability standards are related to production, investme
Saccharomyces cerevisiae has emerged as a versatile platform for whole-cell biocatalysis, owing to its intrinsic regeneration of cofactors and amenability to genetic engineering. However, efficient reductive amination of aromatic carbonyls remains challenging due to competing redox pathways and product inhibition by pyruvate. Building on the redox-rewired TMB4133 strain (∆gpd1,2) that accumulates
Strategic University-Industry Collaborations (UICs) are vital for innovation, yet evaluating their multifaceted outcomes presents a significant challenge. This thesis addresses this gap by investigating performance measurement in UICs through an in-depth case study of the long-standing strategic partnership between Tetra Pak and Lund University. By employing a qualitative methodology, incorporatin
This master’s thesis maps and compares local literary networks within UNESCO’s Cities of Literature, with the aim of understanding how such networks are structured, what their functions are and how they are controlled and developed. Drawing on concepts from social network analysis and Bourdieu’s theories of social fields, capital and habitus, the study combines quantitative and qualitative methods
As Climate Change increases the frequency and severity of wildfires in British Columbia, communities at the Wildland Urban Interface face escalating risks. This thesis explores the challenges and opportunities of community engagement in wildfire management in the city of Kamloops, one of the most fire-prone urban areas in British Columbia. Employing a single-case study design, the research is base
Libraries of things, non-for-profit physical spaces where people borrow objects they would otherwise buy, have spread over Europe, the U.S., and Canada and have now emerged in Mexico City, where challenges to sustainability such as increased consumption levels and insufficient waste management abound. Collaborative economy initiatives like libraries of things are exposed as more sustainable altern
