Treatment of Surgical Scars with Fractional Carbon Dioxide (CO) Laser: A Randomized Controlled Trial.

The aim of this study was to compare the long-term effects of fractional carbon dioxide (CO) laser treatment with traditional therapy on surgical scars by analyzing and comparing observational indicators. A randomized controlled trial was conducted on 116 patients who received scar treatment in our hospital, of which 58 patients received fractional CO laser treatment, and 58 patients received injection treatment. The outcome measures comprised the Vancouver Scar Scale (VSS) and the Patient and Observer Scar Assessment Scale (POSAS).

Interspecies interactions mediated by arginine metabolism enhance the stress tolerance of against .

Colorectal cancer (CRC) is a common cancer accompanied by microbiome dysbiosis. Exploration of probiotics against oncogenic microorganisms is promising for CRC treatment. Here, differential microorganisms between CRC and healthy control were analyzed.

A molecular module improves rice grain quality and yield at high temperatures.

Excessive temperatures during grain filling can compromise endosperm starch biosynthesis and decrease grain quality and yield in rice. However, the molecular mechanisms underlying these remain unclear. Here, we show that heat shock protein OsHsp40-1 interacts with and elevates the ATPase activity of OsHsp70-2 in rice.

Molecular dynamics of chemotactic signalling orchestrates dental pulp stem cell fibrosis during aging.

Aging often triggers dental pulp fibrosis, resulting in clinical repercussions such as increased susceptibility to dental infections, compromised tooth vitality, and reduced responsiveness to dental interventions. Despite its prevalence, the precise molecular mechanisms underlying this condition remains unclear. Leveraging single-cell transcriptome analysis from both our own and publicly available datasets, we identified Ccrl2 macrophages as particularly vulnerable during the early stages of aging.

Temporal Dynamics of Moderate-Intensity Transcranial Static Magnetic Stimulation in Young Adults.

Background: Transcranial static magnetic stimulation (tSMS) as a new noninvasive brain stimulation (NIBS) technique is gradually gaining widespread attention. This study aims to investigate the effects of tSMS on the excitability of the somatosensory cortex in healthy adults.

Methods: Forty healthy volunteers were recruited and randomly assigned to either the intervention group (tSMS) or the control group (sham), with 20 participants in each.
