Challenges With the Intolerance of Biologics in Severe Eosinophilic Asthma: The Risk of Exacerbations Is Time-Dependent With the Rise of Eosinophils.

Patients with severe eosinophilic asthma (SEA) can benefit from biologic therapy but some subjects may present an immune-mediated side effect. These patients will not meet the treatment goals and might have an increased risk of exacerbations. Monitoring these patients by determining blood eosinophil (BE) levels could be one of the tools that may allow a follow-up to prevent a worsening of asthma or exacerbations.

Radiation Chemistry Reveals the Reaction Mechanisms Involved in the Reduction of Vinylene Carbonate in the Solid Electrolyte Interphase of Lithium-Ion Batteries.

A safe and efficient lithium-ion battery requires including an additive in the electrolyte. Among the additives used, vinylene carbonate (VC) is particularly interesting, because it leads to the formation of a stable and protective solid electrolyte interphase (SEI) on the negative electrode. However, the reduction behavior of VC, resulting in polymer formation, is complex, and many questions remain as to the corresponding reaction mechanisms.

Short-Term Changes in Food Spatial Distribution by Zoo Husbandry Practices Increase Agonism and Affect Feeding Behavior in Chilean Flamingos (): A Case Study.

Short-term modifications to animals' enclosures, stemming from zoo husbandry practices, can significantly impact animal behavior and, consequently, their welfare. In this case study, we examined a captive-bred population of 23 adult Chilean flamingos () during a non-breeding season to evaluate whether short-term alterations in the spatial distribution of feeders would affect the birds' feeding and agonistic behaviors. Initially, we developed an ethogram to establish baseline behavioral data.

Synthesis and biological evaluation of 4,7,9-trisubstituted benzoxazepines as antileishmanial agents.

Herein we report a series of antileishmanial analogues derived from 4-[(3,5-dimethyl-4-isoxazolyl)acetyl]-9-[(1-methyl-3-piperidinyl)methoxy]-7-(5-methyl-2-thienyl)-2,3,4,5-tetrahydro-1,4-benzoxazepine (1), which was identified through a previously reported high-throughput phenotypic screen. The analogue series was designed, synthesized, and evaluated for antileishmanial activity to establish pharmacophore elements and preliminary structure-activity relationships as key steps in validating the series for further optimization. This study led to identification of the early lead compound 46, which exhibited sub-micromolar proliferation inhibitory activity against intra-macrophage L.

Preclinical development of SGN-CD47M: Protease-activated antibody technology enables selective tumor targeting of the innate immune checkpoint receptor CD47.

CD47 is a cell surface glycoprotein that is expressed on normal human tissues and has a key role as a marker of self. Tumor cells have coopted CD47 overexpression to evade immune surveillance and thus blockade of CD47 is a highly active area of clinical exploration in oncology. However, clinical development of CD47-targeted agents has been complicated by its robust expression in normal tissues and the toxicities that arise from blocking this inhibitory signal.
