Objectives: The early detection of preterm infants (PI) at risk for intraventricular hemorrhage (IVH) and neurological sequelae still constitutes an unsolved issue. We aimed at validating the role of S100B protein in the early diagnosis and prognosis of IVH in PI by means of cerebral ultrasound (CUS) and magnetic resonance imaging (MRI) today considered standard of care procedures.
Methods: We conducted an observational case-control study in 216 PI of whom 36 with IVH and 180 controls. Standard clinical, laboratory, radiological monitoring procedures and S100B urine measurement were performed at four time-points (first void, 24, 48, 96 h) after birth. Cerebral MRI was performed at 40-42 weeks of corrected gestational age.
Results: Elevated (p<0.001, for all) S100B levels were observed in the IVH group at all monitoring time-point particularly at first void when standard monitoring procedures were still silent or unavailable. S100B measured at first void correlated (p<0.001) with the grade of hemorrhage by means of CUS and with the site and extension of neurological lesion (p<0.001, for all) as assessed by MRI.
Conclusions: The present results showing a correlation among S100B and CUS and MRI offer additional support to the inclusion of the protein in clinical daily management of cases at risk for IVH and adverse neurological outcome. The findings open the way to further investigations in PI aimed at validating new neurobiomarkers by means of S100B.

Enoxaparin sodium (ES), a low molecular weight heparin derivative, has recently been recognized for its diverse biological activities. In particular, the ability of heparin to modulate inflammation has been utilized to enhance the biocompatibility of bone implant materials. In this study, we utilized poly (methyl methacrylate) (PMMA), a drug loading bone implant material, as a matrix and combined this with enoxaparin sodium (ES) to create enoxaparin sodium PMMA cement (ES-PMMA) to investigate the regulatory effects of ES on inflammatory responses in bone tissue from an animal model.

Repetitive head impacts from contact sports are associated with an increased risk of neurodegenerative conditions. While studies have examined acute and chronic outcomes in young and deceased athletes, research on middle-aged former athletes remains limited. We employed multiplex biomarker approaches to examine whether brain injury and systemic inflammatory blood biomarkers are reflective of ≥10 years of participation in contact sports in retired, middle-aged amateur athletes.

Microbiota, which plays a vital role in susceptibility to Clostridioides difficile infection (CDI), synthesizes butyrate. Enteric glia is a component of the enteric nervous system (ENS) and is affected by C. difficile toxins A (TcdA) and B (TcdB).

Protein function is driven by transitions between metastable conformations, many of which are not conserved across homologues, offering opportunities for selective drug design. Accurately modeling both backbone and side chain metastability, and generating structures suitable for rigid docking in high-throughput virtual screening, is thus desirable yet challenging. Here, we present a hierarchical AF2RAVE pipeline that integrates AlphaFold2 with machine learning-based enhanced sampling to systematically explore the free energy landscape and metastability of protein systems, particularly at both backbone and side chain levels.

Introduction: Blood-brain barrier (BBB) disruption is one of the most striking changes triggered by status epilepticus, which deserves specific attention in terms of novel treatment approaches targeting epileptogenesis. Uridine is a pyrimidine nucleoside with neuroprotective, antiepileptic and antiepileptogenic effects; however, its mechanism of action is not fully characterized. In this study, we aimed to investigate the short-term outcomes of uridine treatment on status epilepticus-induced-BBB dysfunction in an animal model.
