Oxytocin is a neuropeptide produced by magnocellular neurosecretory neurons located primarily in the supraoptic nucleus and paraventricular nucleus of the hypothalamus. The long axons of these neurons project to the neurohypophysis where oxytocin is released into the general circulation in response to the physiological demands. Oxytocin plays critical roles in female reproductive physiology, specifically in uterine contraction during labor and milk ejection while nursing.

Department of Chemistry and Biochemistry, University of Colorado Colorado Springs, 1420 Austin Bluffs Pwky, Colorado Springs, CO, 80918, USA. Electronic address:

Enzyme-mediated lipid oxidation is an important regulatory event in cell signaling, with oxidized lipids being potent signaling molecules that can illicit dramatic changes in cell behavior. For example, peroxidation of an arachidonoyl poly-unsaturated fatty acid by the human enzyme 15-lipoxygenase-2 (15-LOX-2) has been associated with formation of atherosclerotic plaques. Previous work on synthetically oxidized membranes has shown that oxidized lipid tails will change their conformation to facilitate interactions between the peroxide group and the lipid headgroups.

Background: Whereas mechanical thrombectomy (MT) has become standard-of-care treatment for patients with salvageable brain tissue after acute stroke caused by large-vessel occlusions, the results of MT in patients with medium-vessel occlusions (MEVOs), particularly in the posterior cerebral artery (PCA), are not well known.

Methods: Using data from the international Stroke Thrombectomy and Aneurysm Registry (STAR), we assessed presenting characteristics and clinical outcomes for patients who underwent MT for primary occlusions in the P2 PCA segment. As a subanalysis, we compared the PCA MeVO outcomes with STAR's anterior circulation MeVO outcomes, namely middle cerebral artery (MCA) M2 and M3 segments.

Insights into core-mantle differentiation from bulk Earth melt simulations.

Sci Rep

August 2024

School of Electrical Engineering and Computer Science, Department of Geology and Geophysics, Center for Computation and Technology, Louisiana State University, Baton Rouge, LA, 70803, USA.

The earth is thought to have gone through complex physicochemical changes during the accretion and magma ocean stages. To better understand this evolution process at the fundamental level, we investigate the behavior of a bulk earth melt system by simulating the composition FeMgSiO (in wt%) at high pressure. A deep neural network potential trained by first-principles data can enable accurate molecular dynamics simulation of large supercells that greatly enhances sampling for reliable evaluation of elemental partitioning.

We sought to derive an objective measure of psychomotor slowing from speech analytics during a psychiatric interview to avoid potential burden of dedicated neurophysiological testing. Speech latency, which reflects response time between speakers, shows promise from the literature. Speech data was obtained from 274 subjects with a diagnosis of bipolar I depression enrolled in a randomized, doubleblind, 6-week phase 2 clinical trial.

Background: The role of antiplatelet/anticoagulant therapy is well known for its primary and secondary prevention of sequela from cardiovascular disease by decreasing the incidence of acute cerebral, cardiovascular, peripheral vascular, and other thrombo-embolicevents. The overwhelming data show that the risk of thrombotic events is significantly higher than that of bleeding during surgery after antiplatelet drug discontinuation. It has been assumed that discontinuing antiplatelet therapy prior to performing interventional pain management techniques is a common practice, even though doing so may potentially increase the risk of acute cerebral and cardiovascular events.

Article Synopsis
  • The increasing use of interventional techniques in chronic pain patients on anticoagulant and antiplatelet therapy poses challenges in balancing the bleeding risk from these medications and the thrombosis risk from discontinuation.
  • Guidelines have been developed through a literature review and expert consensus to help assess and manage the risks of bleeding and thrombosis during interventional procedures for these patients.
  • These guidelines provide a framework for healthcare professionals to make informed decisions regarding the continuation or temporary suspension of anticoagulant and antiplatelet therapy in the context of interventional pain management.

Dysregulated lipid metabolism in obesity leads to adipose tissue expansion, a major contributor to metabolic dysfunction and chronic disease. Lipid metabolism and fatty acid changes play vital roles in the progression of obesity. In this proof-of-concept study, Raman techniques combined with histochemical imaging methods were utilized to analyze the impact of a high-fat diet (HFD) on different types of adipose tissue in mice, using a small sample size (n = 3 per group).

The objective of the present study was to compare the effectiveness of dietary supplementation of muramidase (MUR) and 2 phytogenic additives on the growth performance, intestinal morphology, bacteria load, and production of short-chain fatty acids (SCFA) of broiler chickens raised under field-like conditions. A total of 6,400 day-old Ross 308 broiler chicks were randomly selected and distributed into 32 floor pens, with 200 chicks (100 males and 100 females)/pen. The treatment groups were an unsupplemented control, and the experimental groups supplemented with MUR at 35,000 LSU(F)/kg of feed, phytogenic 1 (Phyto 1, based on thymol) at 100g/ton feed, or phytogenic 2 (Phyto 2, based on alkaloids) at 60g/ton feed, for a total period of 41 d.

Protein tyrosine kinases (PTKs) function as key molecules in the signaling pathways in addition to their impact as a therapeutic target for the treatment of many human diseases, including cancer. PTKs are characterized by their ability to phosphorylate serine, threonine, or tyrosine residues and can thereby rapidly and reversibly alter the function of their protein substrates in the form of significant changes in protein confirmation and affinity for their interaction with protein partners to drive cellular functions under normal and pathological conditions. PTKs are classified into two groups: one of which represents tyrosine kinases, while the other one includes the members of the serine/threonine kinases.

  • Iron storage proteins, like vertebrate ferritin and its bacterial counterparts (Bfr and Ftn), are spherical proteins that help manage iron by oxidizing it and storing it safely within their structure to prevent harmful redox cycling.
  • Vertebrate ferritins consist of H and L subunits, with only the H subunits containing the active centers for iron oxidation, while recent findings suggest that bacterial ferritins are actually heteropolymers made up of both Bfr and Ftn subunits.
  • The study reports the structure of Acinetobacter baumannii bacterioferritin, the first example of a heteropolymeric ferritin, where Ftn homodimers oxidize iron and Bfr homod

Background: Thermal ablation has recently become a key therapy for the treatment of colorectal liver metastasis (CLM). However, the role of ablation in combination with resection has not yet been firmly established. We hypothesize that in patients with CLM, those who undergo liver resection with ablation (RA) have similar outcomes compared with those who undergo liver resection only.
