Phthalates are ubiquitous environmental pollutants known for their endocrine-disrupting properties, particularly during critical periods such as pregnancy and early childhood. Phthalates alter lipid metabolism, but the role of prenatal exposure on the offspring lipidome is less understood. In particular, we focused on long chain acylcarnitines - intermediates of fatty acid oxidation that serve as potential biomarkers of mitochondrial function and energy metabolism.

Background: Degenerative spine disease (DSD) encompasses a range of conditions with increasing prevalence and a significant burden of disease. Patients with DSD are often referred to a neurosurgery clinic with lengthy waiting times from referral to consultation. The reported proportion of referred patients who undergo spinal surgery varies from 20.

Cyclic poly(2-methyl-2-oxazine) (-PMOZI) brush shells on Au nanoparticles (NPs) exhibit enhanced stealth properties toward serum and different cell lines compared to their linear PMOZI (-PMOZI) counterparts. While selectively recruiting immunoglobulins, -PMOZI shells reduce overall human serum (HS) protein binding and alter the processing of complement factor 3 (C3) compared to chemically identical linear shells. Polymer cyclization significantly decreases NP uptake by nonphagocytic cells and macrophages in both complement-deficient fetal bovine serum (FBS) and complement-expressing HS, indicating ineffective functional opsonization.

The aim of the present study was to investigate the role of ovarian hormones on dopaminergic regulation of prepulse inhibition (PPI), a measure of sensorimotor gating deficient in schizophrenia and other psychiatric illnesses. Either in adulthood (11 weeks of age) or adolescence (5 weeks of age), female mice underwent ovariectomy (OVX) and were implanted with 17β-estradiol, progesterone, or a combination of these hormones. All mice were tested in adulthood for the acute effect of the dopamine receptor agonist, apomorphine, on PPI.

Nanoparticle radioenhancement offers a promising strategy for augmenting radiotherapy by locally increasing radiation damage to tumor tissue. While past research has predominantly focused on nanomaterials with high atomic numbers, such as Au and HfO, recent work has revealed that their radioenhancement efficacy decreases considerably when using clinically relevant megavoltage X-rays as opposed to the orthovoltage X-rays typically employed in research settings. Here, radiocatalytically active Ti-based nanomaterials for clinical X-ray therapy settings are designed.
