Failure-mode index

Search what already failed

A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.

WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Stride Velocity 95 th Centile Detects Decline in Ambulatory Function Over Shorter Intervals than the 6-Minute Walk Test or North Star Ambulatory Assessment in Duchenne Muscular Dystrophy

Michael Rabbia, Maitea Guridi Ormazabal, Hannah Staunton et al. · 2024 · Journal of Neuromuscular Diseases

Background: Stride Velocity 95th Centile (SV95C) is the first wearable device-derived clinical outcome assessment (COA) to receive European Medicines Agency (EMA) qualification as a primary endpoint in ambulant patients with Duchenne muscular dystrophy (DMD) aged ≥4 years. Objective: To compare SV95C-in its first-ever clinical trial application as a secondary endpoint-with established motor function COAs used in the trial (Four-Stair Climb [4SC] velocity, North Star Ambulatory Assessment [NSAA], and Six-Minute Walk Distance [6MWD]). Methods: SV95C was a secondary endpoint in a subset (n = 47)

The effect of ESG disclosure on firm value in the European context

Atif Mahmood, Asad Mehmood, Simone Terzani et al. · 2025 · Management Decision

Purpose The environmental, social and governance (ESG) topic has recently received increasing attention from scholars due to increasing regulations for firms’ non-financial disclosure with respect to environmental and social issues. For instance, the European Union (EU) recently issued the Corporate Sustainability Reporting Directive (CSRD) in December 2022 and implemented it starting in 2024 in member states. Non-financial disclosure is relevant for various stakeholders and could affect firm value. Therefore, this study aims to examine the effect of ESG disclosure on firm value in the EU cont

Pancreatic cancer: molecular pathogenesis and emerging therapeutic strategies

Enrique Rozengurt, G. Eibl · 2026 · Signal Transduction and Targeted Therapy

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease for which there is no effective treatment. A deep understanding of the mechanisms underlying the molecular pathogenesis, signaling pathways and risk factors leading to PDAC is of paramount importance for identifying novel targets, prognostic markers, preventive strategies, and signature markers for use in specific and personalized therapeutic procedures. Activating somatic mutations in the KRAS oncogene play a critical role in PDAC initiation and maintenance. Here, we highlight the complex interplay between KRAS signaling, the tr

Endometrial Microbiome and Reproductive Receptivity: Diverse Perspectives

Galina Stoyancheva, Nikolina Mihaylova, Maria Gerginova et al. · 2025 · International Journal of Molecular Sciences

The human endometrium, previously considered a sterile environment, is now recognized as a low-biomass but biologically active microbial niche critical to reproductive health. Advances in sequencing technologies, particularly shotgun metagenomics, have provided unprecedented insights into the taxonomic and functional complexity of the endometrial microbiome. While 16S rRNA sequencing has delineated the distinction between Lactobacillus-dominant and non-dominant microbial communities, shotgun metagenomics has revealed additional diversity at the species and strain level, uncovering microbial si

Effects of Changes in the Levels of Damage-Associated Molecular Patterns Following Continuous Veno–Venous Hemofiltration Therapy on Outcomes in Acute Kidney Injury Patients With Sepsis

Jie Wu, Jianan Ren, Qinjie Liu et al. · 2019 · Frontiers in Immunology

Background: Continuous veno–venous hemofiltration (CVVH) could influence immunomodulation by cytokine removal. Damage-associated molecular patterns (DAMPs) are released by injured cells and have roles in sepsis. We investigated if the magnitude of DAMPs removal was associated with mortality in patients with sepsis undergoing CVVH. Methods: We conducted a prospective, observational study on patients acquiring CVVH at department of surgery, Jinling Hospital. Circulating levels of DAMPs (mitochondrial DNA [mtDNA]; nuclear DNA [nDNA]; heat shock protein [HSP]70) and cytokines were measured at the

No significant association of serum klotho concentration with blood pressure and pulse wave velocity in a Chinese population

Wanying Liang, Lihong Wang, Jian‐Hang Wei et al. · 2021 · Scientific Reports

Klotho, an important anti-aging protein, may be related to elevated blood pressure (BP) and arterial stiffness. We aimed to investigate associations between the serum klotho concentration and peripheral/central BP and arterial stiffness based on the carotid-femoral pulse wave velocity (cfPWV) in a Chinese population. We invited all inhabitants aged ≥ 18 years in two Dali communities for participation. The SphygmoCor system was used to record radial arterial waveforms. Aortic waveforms were derived using a generalized transfer function. The central BP was assessed by calibrating the brachial BP

A National and Regional Greenhouse Gas Breakeven Assessment of EVs across North America

Daniel Rasbash, Kevin Joseph Dillman, Jukka Heinonen et al. · 2023 · Sustainability

Electrification is considered key to decarbonizing the transport sector. While electric vehicles (EVs) lack tailpipe emissions, battery and electricity production can lead to significant emissions. This study analysed whether EVs can effectively mitigate GHG emissions in North America, by calculating two GHG breakeven indicators for EVs and comparing them to internal combustion engine vehicles (ICEVs). EV life cycle emissions were compared to those of ICEVs in Canada, Mexico, and the USA. In addition, this study considered potential national electricity grids evolutions and improvements in bat

Abstract Background Age is a well‐established risk factor for thromboembolic events in patients with atrial fibrillation (AF). However, the mechanism underlying the association between age and thromboembolic events in AF remains unknown. Methods The prognostic value of age as a risk factor for thromboembolic events was analyzed using data from the Korean National Health Insurance Service (NHIS). In a large‐scale single‐center registry, cardiac hemodynamic parameters were examined to elucidate the cause of increased risk of thromboembolic events in older patients.

To assess the remineralizing potential of dentin matrix proteins and enamel matrix derivatives (DMPs and EMDs) after application on artificially induced dentin lesions, given the hypothesis that these materials increase the mineral uptake, binding, and mineralization. Forty-eight caries-free human premolars were used. Teeth were cut, polished, and embedded, leaving an open window on the root surface, of which one-third was covered with a flowable composite to preserve the healthy untreated dentin. Then, samples were demineralized in Buskes solution for 33 days. A micro-CT scan prior to treatme
