Background: Ampullary adenocarcinoma (AAC) typically presents at an early stage due to biliary obstruction and therefore might be specifically suitable for minimally invasive pancreatoduodenectomy (MIPD). However, studies assessing MIPD specifically for AAC, including the robotic and laparoscopic approach, are limited. The aim of this study is to compare short- and long-term oncological resection and perioperative outcomes of robotic (RPD), laparoscopic (LPD) and open pancreatoduodenectomy (OPD) performed specifically for AAC.

More work is needed to establish the validity of the Alternative Model of Personality Disorders (AMPD) in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Acceptance of the AMPD as the primary model of personality disorder requires identifying neurocognitive validators of AMPD-defined personality functioning and demonstrating superiority of the AMPD over the traditional categorical model of personality disorder. It is also important to establish the utility of the AMPD in a developmental context given evidence that personality disorder emerges in adolescence.

Deoxyhypusine synthase (DHPS) is an enzyme encoded by the DHPS gene, with high expression in various cancers, including ovarian cancer (OC). DHPS regulates the translation initiation factor EIF5A, and EIF5A2 knockout inhibits OC tumor growth and metastasis by blocking the epithelial-to-mesenchymal transition (EMT) and the TGFβ pathway. In this study, we show that DHPS is amplified in OC patients, and its elevated expression correlates with poor survival.

Mars Sample Return (MSR) has been the highest flagship mission priority in the last two Planetary Decadal Surveys of the National Academies of Science, Engineering, and Medicine (hereafter, "the National Academies") and was the highest priority flagship for Mars in the Decadal Survey that preceded them. This inspirational and challenging campaign, like the Apollo program's returned lunar samples, will potentially revolutionize our understanding of Mars and help inform how other planets are explored. MSR's technological advances will keep the NASA and European Space Agency at the forefront of planetary exploration, and data on returned samples will fill knowledge gaps for future human exploration.

Learning predictive signatures of HLA type from T-cell repertoires.

PLoS Comput Biol

January 2025

Laboratoire de physique de l'École Normale Supérieure, CNRS, PSL University, Sorbonne Université, and Université de Paris, Paris, France.

T cells recognize a wide range of pathogens using surface receptors that interact directly with peptides presented on major histocompatibility complexes (MHC) encoded by the HLA loci in humans. Understanding the association between T cell receptors (TCR) and HLA alleles is an important step towards predicting TCR-antigen specificity from sequences. Here we analyze the TCR alpha and beta repertoires of large cohorts of HLA-typed donors to systematically infer such associations, by looking for overrepresentation of TCRs in individuals with a common allele.

Article Synopsis
  • High-dose methotrexate (MTX) can lead to serious complications like acute kidney injury (AKI), neutropenia, and liver damage, but glucarpidase, an enzyme that breaks down MTX, shows potential benefits.
  • In a study of 708 patients with MTX-AKI across 28 cancer centers, those receiving glucarpidase had a significantly higher chance of kidney recovery and faster recovery times compared to those who did not receive the treatment.
  • Additionally, glucarpidase treatment was associated with lower rates of severe neutropenia and liver enzyme elevation, but there was no notable difference in mortality rates between the two groups.

Sub-5 Ångstrom Porosity Tuning in Calixarene-Derived Porous Liquids via Supramolecular Complexation Construction.

Angew Chem Int Ed Engl

January 2025

Oak Ridge National Laboratory, Chemical Sciences Division, UNITED STATES OF AMERICA.

Precise sub-Ångstrom-level porosity engineering, which is appealing in gas separations, has been demonstrated in solid carbon, polymer, and framework materials but rarely achieved in the liquid phase. In this work, a gas molecular sieving effect in the liquid phase at sub-5 Ångstrom scale is created via sophisticated porosity tuning in calixarene-derived porous liquids (PLs). Type II PLs are constructed via supramolecular complexation between the sodium salts of calixarene derivatives and crown ether solvents.
