No Significant Difference - Unless you are a Jumper

Richard Fendler, Craig Ruff, Milind Shrikhande · 2018 · Online Learning

Much of the e-education literature suggests that there is no significant difference in aggregate student learning outcomes between online and face-to-face instruction. In this study, we develop a model that forecasts the grade that individual students would have most likely earned in the alternate class setting. Students for whom the difference between the actual grade received in one class format (for example, online) and the forecasted grade in the other class setting (for example, face-to-face) is one full letter grade or higher are called “jumpers.” Our findings indicate that jumpers are n

Obeticholic Acid and Other Farnesoid-X-Receptor (FXR) Agonists in the Treatment of Liver Disorders

Stefano Fiorucci, Ginevra Urbani, Eleonora Distrutti et al. · 2025 · Pharmaceuticals

The Farnesoid-X-receptor (FXR) is a bile sensor involved in the regulation of bile acid homeostasis, fibrosis, inflammation, and metabolism. Obeticholic acid (OCA), a semisynthetic derivative of chenodeoxycholic acid (CDCA), initially named 6-ethyl-CDCA or INT-747, is the first in a class of FXR ligands that have been approved for clinical use for the treatment of patients with primary biliary cholangitis (PBC) who are unresponsive or intolerant to ursodeoxycholic acid. In this narrative review, we will examine the current status and future perspective of clinical use of OCA. Based on results

Prognostic and predictive role of EGFR pathway alterations in biliary cancer patients treated with chemotherapy and anti-EGFR

Caterina Peraldo‐Neia, Giuliana Cavalloni, Elisabetta Fenocchio et al. · 2018 · PLoS ONE

The association of anti-EGFR to gemcitabine and oxaliplatin (GEMOX) chemotherapy did not improve survival in biliary tract carcinoma (BTC) patients. Multiple mechanisms might be involved in the resistance to anti-EGFR. Here, we explored the mutation profile of EGFR extracellular domain (ECD), of tyrosine kinase domain (TKD), and its amplification status. EGFR mutational status of exons 12, 18-21 was analyzed in 57 tumors by Sanger sequencing. EGFR amplification was evaluated in 37 tumors by Fluorescent In Situ Hybridization (FISH). Kaplan-Meier curves were calculated using the log-rank test. S

Medium-sized protein language models perform well at transfer learning on realistic datasets

Luiz Carlos Vieira, Morgan L. Handojo, Claus O. Wilke · 2025 · Scientific Reports

Protein language models (pLMs) can offer deep insights into evolutionary and structural properties of proteins. While larger models, such as the 15 billion parameter model ESM-2, promise to capture more complex patterns in sequence space, they also present practical challenges due to their high dimensionality and high computational cost. We systematically evaluated the performance of various ESM-style models across multiple biological datasets to assess the impact of model size on transfer learning via feature extraction. Surprisingly, we found that larger models do not necessarily outperform

The influence of income and testosterone on the validity of facial width-to-height ratio as a biomarker for dominance

Emilou Noser, Jessica Schoch, Ulrike Ehlert · 2018 · PLoS ONE

Research has indicated that men's facial width-to-height ratio (fWHR) is part of an evolved system of social dominance, aggression, and power. fWHR has been linked to antisocial behavior, measured by self-reported aggression, but recent studies have failed to replicate this finding. To overcome these inconsistencies, influencing factors such as social status have to be taken into account in order to explain the relationship between fWHR and aggression. In particular, income has been shown to be an important influencing factor in this relationship. Furthermore, previous findings suggested that

Could Alcohol Abuse Drive Intimate Partner Violence Perpetrators’ Psychophysiological Response to Acute Stress?

Sara Vitoria-Estruch, Ángel Romero‐Martínez, Marisol Lila et al. · 2018 · International Journal of Environmental Research and Public Health

Proactively aggressive individuals have been shown to present a different pattern of autonomic nervous system (ANS) dysregulation from that of individuals characterized by reactive violence. Although attempts have been made to classify intimate partner violence (IPV) perpetrators based on ANS reactivity to acute stress, subsequent studies have failed to replicate this classification. Notably, the proposed classification neglected the role of chronic alcohol abuse in ANS dysregulation and the fact that this dysregulation entails an abnormal stress response. The aim of the present study was to a

TREM2 in Neurodegenerative Disorders: Mutation Spectrum, Pathophysiology, and Therapeutic Targeting

Hye-Won Yang, Danyeong Kim, YoungSoon Yang et al. · 2025 · International Journal of Molecular Sciences

TREM2 (triggering receptor expressed on myeloid cells 2) is a membrane-bound receptor primarily expressed on microglia in the central nervous system (CNS). TREM2 plays a crucial role in regulating immune responses, phagocytosis, lipid metabolism, and inflammation. Mutations in the TREM2 gene have been linked to various neurodegenerative diseases, including Alzheimer’s disease (AD), frontotemporal dementia (FTD), Parkinson’s disease (PD), and Nasu–Hakola disease (NHD). These mutations are suggested to impair microglial activation and reduce the ability to clear amyloid aggregates, leading to ex

Searching for the “native” speaker: A preregistered conceptual replication and extension of Reid, Trofimovich, and O’Brien (2019)

Bianca Brown, Botagoz Tusmagambet, Valentino Rahming et al. · 2023 · Applied Psycholinguistics

Abstract This study conceptually replicated and extended Reid, Trofimovich, and O’Brien (2019), who found that native English speakers could be biased positively (or negatively) relative to a control condition in terms of how they rate non-native English speech. Our internet-based study failed to replicate Reid et al. across a wider population sample of “native” speakers ( n = 189). Listeners did not change how they rated non-native English speech after social bias orientations and performed similarly across all five measures of speech and across age and race (Asian, Black, and Caucasian).

Microbial Biofilms as Barriers to Chronic Wound Healing: Diagnostic Challenges and Therapeutic Advances

Yasir Almuhanna · 2025 · Journal of Clinical Medicine

Wound healing is a complex and multistage process that incorporates precise cellular and molecular coordination. The presence of biofilms in chronic wounds adversely affects the wound healing process, as it prolongs the closure of the wound, thus sustaining chronic inflammation. Current data suggest that biofilms are present in almost all chronic wounds, which leads to significant challenges in diagnosis and treatment. Traditional detection methods, such as cultures and light microscopy, often fail to detect biofilms; however, sophisticated molecular and imaging techniques are constrained by t

What Do Cognitive Networks Do? Simulations of Spoken Word Recognition Using the Cognitive Network Science Approach

Michael S. Vitevitch, Gavin J. D. Mullin · 2021 · Brain Sciences

Cognitive network science is an emerging approach that uses the mathematical tools of network science to map the relationships among representations stored in memory to examine how that structure might influence processing. In the present study, we used computer simulations to compare the ability of a well-known model of spoken word recognition, TRACE, to the ability of a cognitive network model with a spreading activation-like process to account for the findings from several previously published behavioral studies of language processing. In all four simulations, the TRACE model failed to retr

When Science Replaces Religion: Science as a Secular Authority Bolsters Moral Sensitivity

Onurcan Yılmaz, Hasan G. Bahçekapılı · 2015 · PLoS ONE

Scientific and religious thinking compete with each other on several levels. For example, activating one generally weakens the other. Since priming religion is known to increase moral behaviour and moral sensitivity, priming science might be expected to have the opposite effect. However, it was recently demonstrated that, on the contrary, science priming increases moral sensitivity as well. The present set of studies sought to replicate this effect and test two explanations for it. Study 1 used a sentence unscrambling task for implicitly priming the concept of science but failed to replicate i

Systemic Activation of TLR3-Dependent TRIF Signaling Confers Host Defense against Gram-Negative Bacteria in the Intestine

Jose Ruiz, Saravana Kanagavelu, Claudia Flores et al. · 2016 · Frontiers in Cellular and Infection Microbiology

Recognition of Gram-negative bacteria by toll-like receptor (TLR)4 induces MyD88 and TRIF mediated responses. We have shown that TRIF-dependent responses play an important role in intestinal defense against Gram-negative enteropathogens. In the current study, we examined underlying mechanisms of how systemic TRIF activation enhances intestinal immune defense against Gram-negative bacteria. First we confirmed that the protective effect of poly I:C against enteric infection of mice with Yersinia enterocolitica was dependent on TLR3-mediated TRIF signaling by using TLR3-deficient mice.

Significant Differences in RNA Structure Destabilization by HIV-1 Gag∆p6 and NCp7 Proteins

Micah J. McCauley, Ioulia Rouzina, Jasmine Li et al. · 2020 · Viruses

Retroviral nucleocapsid (NC) proteins are nucleic acid chaperones that play distinct roles in the viral life cycle. During reverse transcription, HIV-1 NC facilitates the rearrangement of nucleic acid secondary structures, allowing the transactivation response (TAR) RNA hairpin to be transiently destabilized and annealed to a complementary RNA hairpin. In contrast, during viral assembly, NC, as a domain of the group-specific antigen (Gag) polyprotein, binds the genomic RNA and facilitates packaging into new virions. It is not clear how the same protein, alone or as part of Gag, performs such d
