A novel putative capsular polysaccharide consisting of D-Glcp and D-Fruf in the molar ratio of 1:1 was isolated as minor constituent from the lipopolysaccharide (LPS) fraction of Pseudomonas (Burkholderia) caryophylli. Its structure was determined, using mainly one- and two-dimensional NMR spectroscopy, as: -->6)-alpha-D-Glcp-(1-->1)-beta-D-Fruf-(2-->.

Importance: Autoantibodies targeting astrocytes, such as those against glial fibrillary acidic protein (GFAP) or aquaporin protein 4, are crucial diagnostic markers for autoimmune astrocytopathy among central nervous system (CNS) autoimmune disorders. However, diagnosis remains challenging for patients lacking specific autoantibodies.
Objective: To characterize a syndrome of unknown meningoencephalomyelitis associated with an astrocytic autoantibody.

Glioblastoma (GBM), the most malignant primary brain tumor in adults, has poor prognosis irrespective of therapeutic advances due to its radio-resistance and infiltrative growth into brain tissue. The present study assessed functions and putative druggability of BRCA1-associated ATM activator 1 (BRAT1) as a crucial factor driving key aspects of GBM, including enhanced DNA damage response and tumor migration. By a stable depletion of BRAT1 in GBM and glioma stem-like (GSC) cell lines, we observed a delay in DNA double-strand break repair and increased sensitivity to radiation treatment, corroborated by in vitro and in vivo studies demonstrating impaired tumor growth and invasion.

Nuclear factor-κB (NF-κB)/p65, a vital signaling molecule in the NF-κB pathway, participates in diverse physiological functions and host-virus interactions. However, the involvement of NF-κB/p65 in fish virus infection remains poorly understood. In this study, we explored the role of the p65 in virus infection and its impact on IL-18 regulation in largemouth bass (Micropterus salmoides).

We systematically reviewed the current evidence assessing blood and CSF mtDNA levels and variant burden in Parkinson's disease (PD), Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS). Multiple sclerosis (MS) was also included as a paradigm of chronic neuroinflammation-driven neurodegeneration.

The utilization of chemical pesticides recovers 30%-40% of food losses. However, their application has also triggered a series of problems, including food safety, environmental pollution, pesticide resistance, and incidents of poisoning. Consequently, green pesticides are increasingly seen as viable alternatives to their chemical counterparts.
