Objective: Oxidative stress and a generalized inflammatory state are features of preeclampsia (PE). The objective of this study was to compare the levels of products of inflammatory reaction and oxidative stress markers in patients with PE, and to determine the relationship between oxidative stress and inflammation in PE.
Methods: Plasma concentrations of high-sensitive C-reactive protein (hs-CRP), interleukin (IL)-6, tumor necrosis factor-alpha (TNF-alpha), malondialdehyde (MDA), and 8-isoprostane were measured in 53 women with PE and 20 age- and BMI-matched normotensive women.
Results: The plasma concentrations of hs-CRP, IL-6, TNF-alpha, and 8-isoprostane were significantly higher in women with PE than in those with normotensive pregnancies, and these parameters, except for 8-isoprostane, were markedly elevated in those with severe PE (SPE), rather than mild PE (MPE). Moreover, plasma levels of 8-isoprostane, not MDA, were significantly correlated with the plasma levels of hs-CRP, IL-6, and TNF-alpha in patients with PE.
Conclusions: These findings suggest that oxidative stress and inflammatory reaction are closely associated with PE, and the interactions between them may participate in the pathogenesis of PE.

As a universal language across the bacterial kingdom, the quorum sensing signal autoinducer-2 (AI-2) can coordinate many bacterial group behaviors. However, unknown AI-2 receptors in bacteria may be more than what has been discovered so far, and there are still many unknown functions for this signal waiting to be explored. Here, we have identified a membrane-bound histidine kinase of the pathogenic bacterium , AsrK, as a receptor that specifically detects AI-2 under low boron conditions.

Background: Leukemia may form at any age, from newborns to the elderly, and accounts for considerable mortality worldwide.
Objectives: Nerolidol (NRD) is isolated from the aromatic florae oils and was found to have anticancer activities. However, the role of NRD in antiproliferative and apoptosis actions in acute lymphoblastic leukemia (ALL) is unclear.
Background: Prostaglandin E (PGE) in the rostral ventrolateral medulla (RVLM) has been recognized as a pivotal pressor substance in hypertension, yet understanding of its effects and origins in the RVLM remains largely elusive. This study aimed to elucidate the pivotal enzymes and molecular mechanisms underlying PGE synthesis induced by central Ang II (angiotensin II) and its implications in the heightened oxidative stress and sympathetic outflow in hypertension.
Methods And Results: RVLM microinjections of PGE and Tempol were administered in Wistar-Kyoto rats.

One notable consequence of climate change is an increase in the frequency, scale and severity of heat waves. Heat waves in terrestrial habitats (atmospheric heat waves, AHW) and marine habitats (marine heat waves, MHW) have received considerable attention as environmental forces that impact organisms, populations and whole ecosystems. Only one ecosystem, the intertidal zone, experiences both MHWs and AHWs.

Aims: This study aimed to develop Imatinib Mesylate (IMT)-loaded Poly Lactic-co-Glycolic Acid (PLGA)-D-α-tocopheryl polyethylene glycol succinate (TPGS)- Polyethylene glycol (PEG) hybrid nanoparticles (CSLHNPs) with optimized physicochemical properties for targeted delivery to glioblastoma multiforme.
Background: Glioblastoma multiforme (GBM) is the most destructive type of brain tumor with several complications. Currently, most treatments for drug delivery for this disease face challenges due to the poor blood-brain barrier (BBB) and lack of site-specific delivery.
