Lithium-ion batteries (LIBs) have broad application prospects in many fields because of their high energy density. However, the poor heat resistance of polyolefin membranes and uneven lithium deposition result in battery failure and even infamous thermal runaway behavior. To improve the intrinsic safety of batteries, fire-retardant, thermally conductive, electrospinning strategies are employed to acquire a functional polyacrylonitrile (PAN) nanofiber separator (PAN@FBN/TPP) containing modified boron nitride (FBN) and triphenyl phosphate (TPP).

Traumatic brain injury (TBI) induces neurogenerative disorders affecting severely daily human activities and early diagnosis is a critical requirement for prevention and cure. Here, we induced TBI formation in the Zebra fish, a model organism, by both mechanical (ultrasonic cleaner generated convulsive shock, UGCS) and chemical (pentylenetetrazol, PTZ) methods. The TBI induced cellular and neuronal changes are monitored by measuring the activities of the indicator biomarkers viz.

B cells present in human cutaneous melanoma have been associated with protective or detrimental effects on disease progression according to their phenotype. By using the RET model of spontaneous melanoma and adoptive transfer of B16 melanoma cells, we show that immature and follicular B2 (B2-FO) cells exert a protective effect on melanoma progression by promoting the generation of effector memory T cells and limiting the recruitment of polymorphonuclear myeloid-derived suppressor cells. Unfortunately, this beneficial effect progressively wanes as a consequence of enhanced expression of the IL4-induced gene 1 (IL4I1) enzyme by immature B cells and B2-FO cells.

Article Synopsis
  • COVID-19 emerged in December 2019 in China and significantly impacted healthcare workers worldwide, particularly in Sub-Saharan Africa where understanding of vaccine responses is limited.
  • A study in Côte d'Ivoire assessed IgG antibody responses to the SARS-CoV-2 vaccine among 77 healthcare workers, revealing that all participants developed antibodies with 88.3% exhibiting strong responses.
  • Factors such as gender and previous COVID-19 infection history influenced IgG levels, while vaccine type and dosage did not affect the titer outcomes.

Respiratory manifestations related to the intake of non-steroidal anti-inflammatory drugs (NSAIDs) during the treatment of the painful vaso-occlusive crisis of sickle cell disease are either a type I hypersensitivity mechanism of the Gell and Coombs classification, or a pharmacological mechanism of NSAIDs. The use of NSAIDs is essential in the Abidjan school because of the absence of therapeutic alternatives in the management of the inflammatory crisis of this disease. The induction of tolerance to NSAIDs initiated by the authors has had clear clinical success.
