MNase stratification reveals heterogeneous 5hmC in naive B cells.

DNA demethylation is essential for gene activation and is primarily mediated by the Ten-Eleven-Translocation (TET) dioxygenase family. TET initiates the demethylation by oxidizing 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), a chemically stable derivative that is not only an intermediate in demethylation but also an epigenetic mark. 5hmC is enriched at active gene bodies, promoters, and enhancers that exist at accessible chromatin.

SALSA: a novel flow cytometry assay to detect ascorbate at the single-cell level.

Ascorbate (AA) is an essential antioxidant and enzymatic cofactor with emerging roles in epigenetic regulation, redox biology, and immune function. However, single-cell quantification of intracellular AA has remained technically challenging. Here, we present SALSA (Single-cell Ascorbate Level Sensing Assay), a novel flow cytometry-based method that enables sensitive, specific detection of intracellular AA at the single-cell level.

Phase 2 Assessment of a New Functional Pain Scale by Comparing It to Traditional Pain Scales.

Background Assessment of pain has always been subjective and is commonly assessed using a numeric pain scale (NPS) or Wong-Baker faces scale. The pain intensity score is not standardized and relies on individuals' past experiences. The disadvantage of using such pain assessment scales and treating the numbers can lead to overdosing on analgesics leading to unwanted side effects.

Pectointercostal fascial plane block for rescue pain management of traumatic sternal fracture following inadequate thoracic epidural block: a case report.

Adequate pain control after multisystem trauma including the chest wall is essential for improved patient outcomes, especially with sternum and rib fractures. The thoracic epidural is considered the gold standard in pain management of thoracic injury; however, failure or patchy epidural is not uncommon. Pectointercostal fascial plane block (PIFB) is regularly used in cardiac surgery to provide analgesia to the anterior chest wall; however, there are few reports of PIFB being used as a primary block for the management of thoracic injuries.

Micro but mighty-Micronutrients in the epigenetic regulation of adaptive immune responses.

Micronutrients are essential small molecules required by organisms in minute quantity for survival. For instance, vitamins and minerals, the two major categories of micronutrients, are central for biological processes such as metabolism, cell replication, differentiation, and immune response. Studies estimated that around two billion humans worldwide suffer from micronutrient deficiencies, also known as "hidden hunger," linked to weakened immune responses.
