Abstract Background: Osteoarthritis (OA) is the most common joint disorder globally and a major cause of disabiltiy with the knee joint responsible for 80% of the disease burden. Progressive degenerative changes in cartilage tissue result in deterioration and loss of articular cartilage. Cartilage has poor capacity of healing and the detection of degeneration usually occurs at a stage of progressi

We introduce rigorous theory for deriving first and second order backpropagation methods for Deep Neural Networks (DNN) whilst satisfying existing theory in DNN optimization. We begin by formally defining a neural network with its respective components and state the first and second order chain rule with respect to its partial derivatives. The partial derivatives in the chain rule formula are rela

The capacity to learn and reproduce vocal sounds has evolved in phylogenetically distant tetrapod lineages. Vocal learners in all these lineages express similar neural circuitry and genetic factors when perceiving, processing, and reproducing vocalization, suggesting that brain pathways for vocal learning evolved within strong constraints from a common ancestor, potentially fish. We hypothesize th

The use of Islamic symbols in metal music has, until now, been a rare phenomenon. A few years ago, some black metal-bands in Istanbul started using Islamic symbols in both their artwork and lyrics, often in an anti-Islamic fashion. Although research on metal music is well established, little has been done on the relationship between black metal and Islam. This thesis explores the relationship betw

Predicting live birth after the first IVF/ICSI treatment is challenging, as many factors may interact to affect IVF/ICSI outcomes. Adenomyosis is one factor that impacts live birth rates. Machine learning algorithms have been shown valuable for detecting complex dependencies and predicting outcomes in different clinical settings. We aimed to develop a prediction model for live birth after IVF/ICSI

Following the line of the former Iron Curtain, the European Green Belt links protected areas across 24 countries, and restores key wildlife populations, wetlands and rural livelihoods. Its success proves that rewilding-grounded nature-based solutions can transform war-scarred frontiers into biodiversity-rich, climate-resilient lifelines, and challenges policymakers to replicate such mega-corridors

A key step in lipolytic activation of adipocytes is the translocation of hormone-sensitive lipase (HSL) from the cytosol to the surface of the lipid storage droplet. Adipocytes from perilipin-null animals have an elevated basal rate of lipolysis compared with adipocytes from Wild-type mice, but fail to respond maximally to lipolytic stimuli. This defect is downstream of the p-adrenergic receptor-a

The kinin B1 receptor (B1R) is a G protein-coupled receptor with pro-inflammatory activity that is latent in healthy tissues but induced by tissue insult. Here, we investigated if B1R homo-oligomerization is a possible mechanism regulating the presentation of this receptor at the level of maturation and trafficking to the cell surface. To this end, we used HEK293 cells stably expressing N-terminal

The aggregating proteoglycans (aggrecan, versican, neurocan, and brevican) are important components of many extracellular matrices. Their N-terminal globular domain binds to hyaluronan, but the function of their C-terminal region containing a C-type lectin domain is less clear. We now report that a 90-kDa protein copurifies with recombinant lectin domains from aggrecan and versican, but not from t

The actinomycete Corynebacterium glutamicum grows as rod-shaped cells by zonal peptidoglycan synthesis at the cell poles. In this bacterium, experimental depletion of the polar DivIVACG protein resulted in the inhibition of polar growth; consequently, these cells exhibited a coccoid morphology. This result demonstrated that DivIVA is required for cell elongation and the acquisition of a rod shape.

Purpose: The purpose of this paper is to shed light on which role authenticity plays in mobile dating apps, an environment where users can present themselves only with a limited amount of information. By investigating how users create their profiles and evaluate others, the existing knowledge on authenticity and self-presentation can be advanced. Methodology: The research applied a relativist and

A review of the current evidence for internal fixation versus hemiarthroplasty versus primary total hip arthroplasty for displaced femoral neck fractures was undertaken. At the meta-analysis level no difference in postoperative pain, function, or quality of life can yet be demonstrated. A significant difference in mortality has also not been found, but a trend towards higher mortality after primar
