The analysis of cell-free tumor DNA (ctDNA) and proteins in the blood of patients with cancer potentiates a new generation of non-invasive diagnostic approaches. However, confident detection of tumor-originating markers is challenging, especially in the context of brain tumors, where these analytes in plasma are extremely scarce. Here, we apply a sensitive single-molecule technology to profile multiple histone modifications on individual nucleosomes from the plasma of patients with diffuse midline glioma (DMG).

Preslaughter stress induced a negative energy balance of broilers, resulted in an accelerated glycolysis and finally led to an inferior meat quality. The present study aimed to investigate the effects of creatine monohydrate (CMH) supplementation on muscle energy storage, antioxidant capacity, the glycolysis of postmortem muscle and the metabolite profiles in muscle of broilers subjected to preslaughter transport. Two hundred and forty broilers were chosen and randomly allocated into three treatments (group A, group B and group C), comprising 8 replicates (10 broilers each replicate).

The aim of this study was to analyze the association between circulating amino acids and central and peripheral body temperature in subjects with and without fibromyalgia syndrome (FMS). A total of 47 patients with FMS and 59 healthy subjects were included in the study. The concentration of amino acids was determined in serum samples using a fluorimeter coupled with a high-performance liquid chromatography system.

Developing a reliable model to predict AMI occurrence in these patients holds the potential to expedite early diagnosis and intervention. This study is aimed at establishing a circulating amino acid-assisted model, incorporating amino acid profiles alongside clinical variables, to predict AMI risk.

Serine 31 is a phospho-site unique to the histone H3.3 variant; mitotic phospho-Ser31 is restricted to pericentromeric heterochromatin, and disruption of phospho-Ser31 results in chromosome segregation defects and loss of p53-dependant G cell-cycle arrest. Ser31 is proximal to the H3.
