Impact of Pancreatic Resection on Survival in Locally Advanced Resectable Gastric Cancer

Shih-Chun Chang, Chi-Ming Tang, Puo‐Hsien Le et al. · 2021 · Cancers

Whether gastric adenocarcinoma (GC) patients with adjacent organ invasion (T4b) benefit from aggressive surgery involving pancreatic resection (PR) remains unclear. This study aimed to clarify the impact of PR on survival in patients with locally advanced resectable GC. Between 1995 and 2017, patients with locally advanced GC undergoing radical-intent gastrectomy with and without PR were enrolled and stratified into four groups: group 1 (G1), pT4b without pancreatic resection (PR); group 2 (G2), pT4b with PR; group 3 (G3), positive duodenal margins without Whipple’s operation; and group 4 (G4)

Ilixadencel, a Cell-based Immune Primer, plus Sunitinib Versus Sunitinib Alone in Metastatic Renal Cell Carcinoma: A Randomized Phase 2 Study

Magnus Lindskog, Anna Laurell, Anders Kjellman et al. · 2022 · European Urology Open Science

Background: The prognosis of patients with synchronous metastatic renal cell carcinoma (mRCC) is poor. Whereas single-agent tyrosine kinase inhibition (TKI) is clearly insufficient, the effects can be enhanced by combinations with immune checkpoint inhibitors. Innovative treatment options combining TKI and other immune-stimulating agents could prove beneficial. Objective: To evaluate the clinical effects on metastatic disease when two doses of allogeneic monocyte-derived dendritic cells (ilixadencel) are administrated intratumorally followed by nephrectomy and treatment with sunitinib compared

Ocular Surface Ion Transport and Dry Eye Disease

Ethan S. Lindgren, Onur Çil, A. S. Verkman et al. · 2022 · Current Ophthalmology Reports

Purpose of Review: To review the role of ocular surface epithelial (corneal and conjunctival) ion transporters in the pathogenesis and treatment of dry eye disease (DED). Recent Findings: Currently, anti-inflammatory agents are the mainstay of DED treatment, though there are several agents in development that target ion transport proteins on the ocular surface, acting by pro-secretory or anti-absorptive mechanisms to increase the tear fluid Film volume. Activation or inhibition of selected ion transporters can alter tear fluid osmolality, driving water transport onto the ocular surface via osm

Implications of root morphology and anatomy for water deficit tolerance and recovery of grapevine rootstocks

David García Alonso, Ignacio Buesa, Luis Flor et al. · 2025 · Frontiers in Plant Science

The intensification of drought conditions due to climate change poses a major challenge to sustainable grape production. Rootstocks are essential in supporting grapevine water uptake and drought resilience; however, their physiological responses to water stress are not fully understood. Under the hypothesis that root morphology and anatomy may be key traits in grapevine tolerance to water deficit, this study aimed to investigate these traits across diverse rootstocks under progressive water deficit and recovery phases. Thirteen genotypes, including commercial rootstocks and recently bred RG-se

Regional models do not outperform continental models for invasive species

Catherine S. Jarnevich, Helen R. Sofaer, Pairsa Belamaric et al. · 2022 · NeoBiota

Aim : Species distribution models can guide invasive species prevention and management by characterizing invasion risk across space. However, extrapolation and transferability issues pose challenges for developing useful models for invasive species. Previous work has emphasized the importance of including all available occurrences in model estimation, but managers attuned to local processes may be skeptical of models based on a broad spatial extent if they suspect the captured responses reflect those of other regions where data are more numerous. We asked whether species distribution models fo

New cycle, same old mistakes? Overlapping vs. discrete generations in long-term recurrent selection

Marlee R. Labroo, Jessica Rutkoski · 2022 · BMC Genomics

BACKGROUND: Recurrent selection is a foundational breeding method for quantitative trait improvement. It typically features rapid breeding cycles that can lead to high rates of genetic gain. Usually, generations are discrete in recurrent selection, which means that breeding candidates are evaluated and considered for selection for only one cycle. Alternately, generations can overlap, with breeding candidates considered for selection as parents for multiple cycles. With recurrent genomic selection but not phenotypic selection, candidates can be re-evaluated by using genomic estimated breeding v

Predicting ‘Brainage’ in late childhood to adolescence (6-17yrs) using structural MRI, morphometric similarity, and machine learning

Daniel Griffiths-King, Amanda Wood, Jan Novák · 2023 · Scientific Reports

Brain development is regularly studied using structural MRI. Recently, studies have used a combination of statistical learning and large-scale imaging databases of healthy children to predict an individual's age from structural MRI. This data-driven, predicted 'Brainage' typically differs from the subjects chronological age, with this difference a potential measure of individual difference. Few studies have leveraged higher-order or connectomic representations of structural MRI data for this Brainage approach. We leveraged morphometric similarity as a network-level approach to structural MRI t

Target Size Manipulations Affect Error-Processing Duration and Success Perceptions but not Behavioural Indices of Learning

Nicole T. Ong, Jamie Hawke, Nicola J. Hodges · 2019 · Brain Sciences

We evaluated if and how success perceptions, through target size manipulations, impact processes related to motor learning. This work was based on recent literature suggesting that expectations and self-efficacy exert a direct impact on learning. We measured arousal, kinematics, learner expectancies, motivation, and outcomes in a dart-throwing task. Novices (n = 29) were assigned to either a “Large-target” (horizontal target, 10-cm high) or “Small-target” (2-cm high) group for practice (t = 90), and both groups completed 24-h retention tests.

How to get rid of the belief bias: Boosting analytical thinking via pragmatics

Laura Macchi, Francesco Poli, Laura Caravona et al. · 2019 · Europe’s Journal of Psychology

The previous research attempts to reduce the influence of the belief bias on deductive thinking have often been unsuccessful and, when they succeeded, they failed to replicate. In this paper, we propose a new way to see an old problem. Instead of considering the analytical abilities of the respondent, we focus on the communicative characteristics of the experimental task. By changing the pragmatics into play through a subtle manipulation of the instruction of the syllogism problem, we obtained a strong improvement in the accuracy of the performance in both untrained and trained in logic respon
