Article Synopsis
  • A 60-year-old woman was diagnosed with advanced small bowel neuroendocrine tumor (NET G3) that had spread to the liver and was showing aggressive metabolic activity.
  • After initial treatment with chemotherapy, her disease progressed, leading to the use of targeted therapy called PRRT, combining 177Lu-DOTA-octreotate and 225Ac-DOTA-octreotate, which stabilized her condition.
  • A novel treatment with 225Ac-DOTA-LM3, a somatostatin receptor antagonist, resulted in an improved treatment response, marking the first documented evidence that this approach may be more effective than standard treatments for this type of cancer.

Comprehenders generate expectations about upcoming lexical items in language processing using various types of contextual information. However, a number of studies have shown that argument roles do not impact neural and behavioral prediction measures. Despite these robust findings, some prior studies have suggested that lexical prediction might be sensitive to argument roles in production tasks such as the cloze task or in comprehension tasks when additional time is available for prediction.

Background: An increasing number of HCC develops in the context of metabolic dysfunction-associated steatotic liver disease and its inflammatory form, metabolic dysfunction-associated steatohepatitis, even in the absence of cirrhosis. Chronic metabolic inflammation is the driving force of metabolic dysfunction-associated steatotic liver disease progression and a key factor in hepatocarcinogenesis. Given the prominent role of IL-1 signaling in inflammation and metabolic diseases, we investigated the relevance of the hepatocyte-specific IL-1 receptor type 1 knockout in metabolic dysfunction-associated steatohepatitis-related noncirrhotic HCC.

Understanding Rate and Capacity Limitations in Li-S Batteries Based on Solid-State Sulfur Conversion in Confinement.

ACS Appl Mater Interfaces

December 2024

Department of Information Technology and Electrical Engineering, ETH Zürich, Gloriastrasse 35, 8092 Zürich, Switzerland.

Li-S batteries with an improved cycle life of over 1000 cycles have been achieved using cathodes of sulfur-infiltrated nanoporous carbon with carbonate-based electrolytes. In these cells, a protective cathode-electrolyte interphase (CEI) is formed, leading to solid-state conversion of S to LiS in the nanopores. This prevents the dissolution of polysulfides and slows capacity fade.

Changing the reaction pathway of the CaAl oxidation using ball milling.

Dalton Trans

January 2025

Inorganic Solid State Chemistry, Saarland University, Campus C4.1, 66123 Saarbrücken, Germany.

Article Synopsis
  • The study investigates the oxidation of calcium aluminum (CaAl) using elemental oxygen (O) and a different oxidizing agent (HO), noting that the reactions proceed via intermediates before forming products.
  • High-energy ball milling is shown to reduce the crystallite size of CaAl and introduce defects, which alters the reaction pathways compared to more crystalline forms.
  • The research indicates that even brief ball milling (5 minutes) markedly changes the energy patterns of the oxidation reaction, with longer milling times (180 minutes) potentially leading to pyrophoric material.

Article Synopsis
  • Conversions from robot-assisted partial nephrectomy to more invasive surgeries happen in about 1-5% of cases, and this study looks at what could predict these conversions.
  • The research analyzed 2,549 patients operated on by 25 surgeons, finding a 3.5% conversion rate linked to factors like older age, higher BMI, tumor size, and the surgeon’s experience.
  • The study concludes that both patient characteristics and surgical expertise significantly impact the likelihood of conversion, suggesting that better training could enhance outcomes and allow for more kidney-sparing procedures.

The epithelial sodium channel (ENaC) plays a key role in osmoregulation in tetrapod vertebrates and is a candidate receptor for salt taste sensation. There are four ENaC subunits (α, β, γ, δ) which form αβγ- or δβγ ENaCs. While αβγ-ENaC is a 'maintenance protein' controlling sodium and potassium homeostasis, δβγ-ENaC might represent a 'stress protein' monitoring high sodium concentrations.

Sodium-Selective Channelrhodopsins.

Cells

November 2024

Dynamics of Fluids, Experimental Physics, Saarland University, 66123 Saarbrücken, Germany.

Channelrhodopsins (ChRs) are light-gated ion channels originally discovered in algae and are commonly used in neuroscience for controlling the electrical activity of neurons with high precision. Initially-discovered ChRs were non-selective cation channels, allowing the flow of multiple ions, such as Na, K, H, and Ca, leading to membrane depolarization and triggering action potentials in neurons. As the field of optogenetics has evolved, ChRs with more specific ion selectivity were discovered or engineered, offering more precise optogenetic manipulation.
